It is an existing USB2.0 male connector 90, which is provided with a plastic base 91 and a metal shell 92, which covers the plastic base 91 A socket space 93 is formed between the metal shell 92 and the plastic base 91. Only one side of the plastic base 91 is provided with a row of contacts 94 exposed in the socket space 93. The current standard of the USB Association is the overall height i is 4.5mm, relative to the half-body height j of the socket space 93 is 2.25mm, and the socket space height k is 1.95mm.

At present, the USB2.0 socket is equipped with a row of contacts on the tongue side. In use, the USB2.0 connector needs to be inserted in the correct direction to make the two contacts connect to power; in order to ensure that the USB connector can be inserted Electrically connected, the two have a fool-proof design in the docking. As shown in Figure 1A, when the mark 97 on the side of the handle 96 of the USB2.0 male connector 90 is facing upwards, it is positive, and the contact 94 is facing upwards. , The electrical connection can be inserted when it is inserted in the forward direction, as shown in Figure 1B, when the USB connector is inserted in the reverse direction, it cannot be inserted, so that the electrical connection can be ensured after insertion. The user usually inserts randomly, so the probability of not inserting is 1/2, so it is often inserted twice, which causes inconvenience in use.

Please refer to Figure 2, which is an existing USB2.0 socket 80, which includes a plastic seat 81, a metal shell 83 and a row of terminals 87. The front end of the plastic seat 81 is integrally provided with a horizontally extending tongue 82.

The above and other objectives, advantages and features of this creation will be more apparent from the detailed description of the following preferred embodiments with reference to the drawings.

Please refer to Figures 3, 4, and 5, which is the first embodiment of this creation. It is a USB2.0 socket, which can be connected to the aforementioned USB2.0 male connector 90, which includes a plastic socket 10, a The tongue 20, a metal shell 30 and two rows of first terminals 40, of which:

The tongue 20 is integrally protruding from the front end of the plastic seat 10, and the front end is thinner and the rear end is thicker. The tongue 20 is tapered from the front to the back, so that the tongue is relatively strong and not easy to break.

A connecting groove 31 is formed in the metal shell 30. The metal shell 30 is provided at the front end of the plastic seat 10 and the tongue 20 is wrapped inside. The height of the rear section of the connecting groove 31 is greater than the height of the insertion port, and the front end of the connecting groove 31 is provided with an introduction inclined surface 36.

Each of the two rows of first terminals 40 has four. The first terminal 40 is provided with an elastic arm 41, a fixing portion 42 and a pin 43. The fixing portion 42 is positioned in the plastic seat 10, and the elastic arm 41 faces The connecting groove 31 extends and is provided with a protruding first contact 44 protruding from one side of the tongue 20, and the first contacts 44 of the two rows of first terminals 40 protruding from both sides of the tongue 20 respectively.

The special feature of this creation is that the space between the connecting groove 31 on both sides of the tongue 20 can enable the USB male plug to be inserted and positioned in both directions, and the USB male plug and the connecting groove 31 are inserted into the first terminal 40 at the maximum oblique angle. When contact 44, the distance between the metal shell of the USB male connector and the first contact is greater than 0.05 mm to ensure that no short circuit is caused.

In order to achieve the above-mentioned two-way electrical connection without short circuit, the design of this embodiment adopts the length of the metal shell 30 to be longer than the conventional one, the length of the tongue 20 is shorter than that of the conventional one, and the first contact 44 is retracted and the thickness of the tongue 20 is smaller. The conventional design is thin, and the design dimensions of this embodiment are as follows: the thickness a of the front end of the tongue is about 1mm, the thickness b of the back end of the tongue is about 1.6mm, the height of the connecting groove c is about 5.8mm, and the positioning plane of the connecting groove 31 The horizontal distance d from the insertion end 35 to the first contact 44 of the first terminal 40 is about 6.6mm, and the space height f on both sides of the tongue is about 2.3mm to 2,4mm, that is, the f at the front end of the tongue is (5.8 mm-1mm)/2=2.4mm, which gradually shrinks toward the rear end of the tongue. Since the f of the rear part of the tongue is still larger than 2.3mm, a concave surface 32 is provided.

In this embodiment, since the tongue is thinner than the conventional one, the tongue 20 is designed to be a tapered shape with a thin front and a thick back in order to increase strength.

The following operating instructions can clearly show that regardless of whether the USB2.0 connector 90 is inclined into the connection slot 31 at any angle, the metal shell 92 will never touch the first contact 44 of the first terminal 40. Please refer to Figure 6, when the USB2. 0 When the contact 94 of the male connector 90 is facing upwards from the insertion port and tilted downwards (the three-dimensional view of the USB2.0 male connector 90 being inserted and tilted downwards is shown in Figure 1A), the USB2.0 male connector 90 is connected to the connection slot When 31 is inserted into the connecting slot at the maximum oblique angle to the horizontal position of the first contact 44 of the first terminal 40, the angle x between the USB2.0 male 90 and the connecting slot 31 is about 11.5 degrees, the USB male The socket space 93 is inserted into the tongue piece 20, and the distance e between the metal shell 92 and the first contact point 44 on the tongue piece is still greater than 0.3mm, so it can ensure that no short circuit will be caused; please refer to Fig. 7, when the USB2 When the .0 male connector 90 is interpolated and turned gradually, the distance e is greater than 0.38mm. At this time, the angle x between the USB2.0 male connector 90 and the connection slot 31 is about 6.5 degrees; please refer to Figure 8. When the USB2.0 male connector 90 is inserted into position again, the contact 94 of the USB2.0 male connector 90 is in contact with the first contact 44 of the first terminal under the tongue. At this time, the distance e is greater than 0.48mm, and the half-body height of the USB2.0 male 90 is 2.25mm, which can fit into the space height f (2.3mm to 2.4mm) below the tongue piece 20, although the rear end of the tongue piece 20 is thick, so The height f of the space becomes smaller, but the rear part of the connecting slot 31 is provided with a concave surface 32 to make up, so that the USB2.0 male connector 90 can still be inserted to the innermost position. At this time, the USB2.0 male connector 90 and the bottom surface of the connecting slot 31 The included angle is about 3 degrees, that is, the USB2.0 male head 90 is positioned obliquely in the connecting slot 31.

Please refer to Figure 9, which is the state where the contact 94 of the USB2.0 male connector 90 faces downwards and is inserted in the reverse direction. At this time, the distance e is also greater than 0.48mm, and the half-body height of the USB2.0 male connector 90 is 2.25mm Then, the space height f (2.3mm to 2.4mm) positioned above the tongue piece 20 is fitted.

As can be seen from the above description, when the USB2.0 male connector 90 is inserted into the connecting slot 31 for positioning, the essentials for the metal shell 92 of the USB2.0 male connector 90 not to contact the first contact 44 are the thickness of the front section of the tongue 20 and the first A contact 44 protrudes from the height of the front section of the tongue 20. Since the socket space height k of the USB2.0 male 90 is 1.95mm, and the first contact 44 needs to have a spring height of about 0.3mm, so It is ensured that the metal shell 92 cannot contact the first contact 44, and the thickness of the front section of the tongue 20 cannot be greater than 1.55 mm.

However, because the user does not insert it in a proper horizontal position, if the insertion angle is too large, the metal shell 92 of the USB2.0 male connector 90 will touch the first contact 44 during the insertion process, which will affect the USB2.0 design. The factor of the maximum oblique insertion angle of the male head 90 is the height c of the connecting groove and the horizontal distance d from the insertion end 35 of the positioning plane of the connecting groove 31 to the first contact 44 of the first terminal 40, which is the height of the connecting groove c The smaller and the larger the horizontal distance d, the smaller the maximum bevel angle of the USB2.0 male plug 90 will be inserted, and the larger the distance e will be. This creation is to increase the horizontal distance d to ensure a safe distance e .

In this creation, the thickness of the tongue, the height of the connecting groove c, and the horizontal distance d from the insertion end 35 of the positioning plane of the connecting groove 31 to the first contact 44 of the first terminal 40 are designed with appropriate dimensions and a new structure is proposed. It can be used for two-way plugging and positioning of the USB connector and will not cause a short circuit.

Please refer to FIG. 10, which is the second embodiment of the present creation, which is roughly the same as the first embodiment. The difference is that the insertion end of the positioning plane of the connecting groove 31 of this embodiment to the first contact 44 of the first terminal 40 The horizontal distance is relatively short. When the USB2.0 male 90 and the connecting slot 31 are inserted into the connecting slot at the maximum oblique angle to the horizontal position of the first contact 44 of the first terminal 40, the USB2.0 male 90 is now The included angle x with the connecting groove 31 is about 28 degrees. The metal shell 92 will touch the first contact 44 under the tongue and cause a short circuit. This is an incorrect embodiment, mainly to explain the implementation of the short circuit. .

Please refer to FIG. 11, which is the third embodiment of the present creation. It is roughly the same as the first embodiment. The difference lies in the insertion end of the positioning plane of the connecting groove 31 of this embodiment to the first contact 44 of the first terminal 40 The horizontal distance is short about 3.55mm, the USB2.0 male 90 and the connection slot 31 are inserted into the connection slot at the maximum oblique angle to the horizontal position of the first contact 44 of the first terminal 40, at this time the USB2. The angle x between the male head 90 and the connecting groove 31 is about 24.5 degrees, and the distance e between the metal shell 92 and the first contact 44 on the tongue is still greater than 0.05mm, which is still barely used without causing a short circuit.

Please refer to Figure 12, which is the fourth embodiment of this creation, which is roughly the same as the first embodiment. The difference is that the thickness of the front end of the tongue of this embodiment is increased by about 1.3mm and the height of the connecting groove c is also increased by about 6.15mm. , When the USB2.0 male head 90 and the connecting slot 31 are inserted into the connecting slot at the maximum oblique angle to the horizontal position of the first contact 44 of the first terminal 40, then the USB2.0 male head 90 and the connecting slot 31 The included angle x is about 14.5 degrees, and the distance e between the metal shell 92 and the first contact 44 on the tongue is still greater than 0.05 mm, which is still barely used without causing a short circuit.

Please refer to FIG. 13, which is the fifth embodiment of this creation. It is roughly the same as the first embodiment. The difference is that the length of the metal shell 30 of this embodiment is shortened by 1mm, and the first contact 44 is contracted by 0.3mm, so the connecting groove The horizontal distance d between the insertion end of the positioning plane of 31 and the first contact 44 of the first terminal 40 is 5.9mm. When the first contact 44 of the terminal 40 is in the horizontal position, the angle x between the USB2.0 male 90 and the connecting slot 31 is about 13.5 degrees, and the distance between the metal shell 92 and the first contact 44 on the tongue e is greater than 0.27mm.

Please refer to FIG. 14, which is the sixth embodiment of this creation. It is roughly the same as the first embodiment. The difference is that the length of the metal shell 30 in this embodiment is increased by 0.5mm and the front end of the metal shell 30 is turned out to form an introduction slope 36. Therefore, the horizontal distance d between the insertion end of the positioning plane of the connecting slot 31 and the first contact 44 of the first terminal 40 is 7.1mm. When the first contact 44 of the first terminal 40 is in a horizontal position, the angle x between the USB2.0 male connector 90 and the connecting slot 31 is about 11.2 degrees, and the metal shell 92 is connected to the first contact under the tongue. The distance e between 44 is greater than 0.3mm.

Please refer to FIG. 15, which is the seventh embodiment of this creation. It is roughly the same as the sixth embodiment. The difference is that the length of the metal shell 30 of this embodiment is shortened and the tongue 20 is lengthened. When the connecting groove 31 is inserted into the horizontal position of the first contact 44 of the first terminal 40 at an excessively oblique angle, the tongue 20 is bent due to the force, and the end of the elastic arm of the first terminal 40 does not press against the tongue. 20. Therefore, the first contact 44 under the tongue stays still and hides in the tongue 20, which further prevents the metal shell 92 from contacting the first contact 44 under the tongue.

Please refer to FIG. 16, which is the eighth embodiment of this creation. It is roughly the same as the first embodiment. The difference is that the front section of the elastic arm 41 of the first terminal 40 of this embodiment is folded back to form a protruding tongue 20 on one side. The first contact 44, so that when the USB2.0 male plug is inserted into the electrical connection, the elastic arm 41 of the first terminal 40 can move smoothly in the direction.

Please refer to Figures 17 and 18, which are the ninth embodiment of this creation. It is roughly the same as the first embodiment. The difference is that a plate is provided in front of the first contact 44 of the elastic arm 41 of the first terminal 40 of this embodiment. With a narrow guide slope 45, the first contacts 44 of the first terminals of the two rows correspond up and down, and the guide slopes 45 of the elastic arms 41 of the first terminals 40 of the two rows are staggered to the left and right and all have a pre-compression against the tongue The sheet 20 is designed in this way. The first terminal 40 has better elasticity, and the guide slopes 45 of the first terminals 40 in the two rows are staggered left and right to have a larger spring space. However, the disadvantage is that when the USB2.0 male plug is inserted into the inclined angle The first contact 44 of the first terminal 40 still moves synchronously when the tongue is forced to bend because it is too large, so that the metal shell 92 can easily contact the first contact 44 on one side of the tongue.

Please refer to Figures 19 and 20, which are the tenth embodiment of this creation. It is roughly the same as the first embodiment. The difference is that the tongue 20 of this embodiment is a flat plate of insulating material with good strength, such as a glass fiber board. Four through holes 23 extending in the same direction as the elastic arm 41 of the first terminal 40 are provided with a long and slender through hole 23. Both sides of the tongue are provided with a welding pad 24 behind each through hole 23. There is a notch 25, the plastic seat 10 is provided with an upper seat 15 and a lower seat 12, and a clamping block 13 is provided on both sides of the lower seat 12 respectively.

In assembly, the fixing portion 42 of the first terminal 40 of the two rows is welded to the solder pad 24, the notch 25 of the tongue 20 is clamped to the block 13 of the lower base 12, and then the upper base 15 is fitted to the lower base. On the base 12, finally the metal shell 30 is fitted and fixed to the front end of the plastic base 10.

The fixing portion 42 is positioned in the plastic seat 10, and the elastic arm 41 faces The connecting groove 31 extends and is provided with a protruding first contact 44 protruding from the convex surface 27 of the tongue 20.

The characteristic of this embodiment is that the space between the connecting groove 31 on both sides of the tongue 20 can enable the USB3.0 male connector to be inserted and positioned in both directions, and the USB3.0 male connector and the connecting groove 31 are inserted into the connecting groove at the maximum oblique angle. When the first contact 44 of the first terminal 40 is in a horizontal position, the distance between the metal shell of the USB3.0 male connector and the first contact is greater than 0.05 mm to ensure that no short circuit is caused.

In order to achieve the above two-way electrical connection without short circuit, this embodiment adopts the following design. The thickness of the circuit board in the front section of the tongue is 0.6mm, the thickness a of the front end of the protruding piece 18 of the rear section of the tongue is about 1.0mm, and the back end of the protruding piece The thickness b is about 1.6mm, the height of the connecting groove c is about 5.8mm, the horizontal distance d from the insertion end 35 of the positioning plane of the connecting groove 31 to the first contact 44 of the first terminal 40 is about 6.6mm, the rear section of the tongue The space height f between the two sides is about 2.3mm to 2,4mm, that is, the f at the front end of the posterior segment of the tongue is (5.8mm-1mm)/2=2.4mm, and it gradually shrinks toward the rear end of the tongue. In order to still be larger than 2.3mm, f is provided with a concave surface 32.

The following operating instructions show that the metal shell 92 of the USB3.0 connector will never touch the first contact 44 of the first terminal 40 when the USB3.0 connector is inclined into the connection slot at any angle. Please refer to Figure 24, the USB3.0 connector 99 The size specifications are roughly the same as the aforementioned USB2.0 connector 90. The only difference is that the USB3.0 connector 99 has a row of 5 internal contacts 95 that can be moved. This should be the connector of the USB3.0 male connector 99 When 94 is facing upward and is inserted into the connecting slot at the maximum oblique angle with the connecting slot 31 to the horizontal position of the first contact 44 of the first terminal 40, the included angle x between the USB3.0 male connector 99 and the connecting slot 31 is about 11.5 degrees, the socket space 93 of the USB3.0 male connector 99 is inserted into the tongue piece 20, and the distance e between the metal shell 92 and the first contact point 44 on the tongue piece is still greater than 0.3mm, so it can ensure that no short circuit is caused. ; Please refer to Figure 25, when the USB3.0 male connector 99 is inserted and turned flat, the distance e is greater than 0.38mm. At this time, the angle x between the USB3.0 male connector 99 and the connection slot 31 is approximately 6.5 degrees; please refer to Figure 26, when the USB3.0 male connector 99 is inserted into the position again, the contact 94 of the USB3.0 male connector 99 and the first contact 44 of the first terminal under the rear section of the tongue Contact, the inner contact point 95 is in contact with the second contact point 211 below the front section of the tongue, and the distance e is greater than 0.48mm at this time, and the half-body height of the USB3.0 male connector 99 is 2.25mm and can be tightly positioned on the The height f of the space below the tongue 20 (2.3mm to 2.4mm), although the rear end of the tongue 20 is thicker, so that the space height f becomes smaller, but the rear section of the connecting groove 31 is provided with a concave surface 32 to make up, so the USB3. 0 male head 99 can still be inserted to the innermost position.

In the same way, when the contact 94 of the USB3.0 male connector 99 faces upwards and is inserted into the positioning state, it is also the same, which will not be described in detail again.

It can be seen from the above description that when the USB3.0 male connector 99 is inserted into the connecting slot 31 and positioned, the essential elements for the metal shell 92 of the USB3.0 male connector 99 not to contact the first contact 44 are the thickness of the front end of the rear section of the tongue 20 and The height of the first contact 44 protruding from the rear section of the tongue 20, since the socket space height k of the USB3.0 male connector 90 is 1.95mm, and the first contact 44 has a spring height of approximately 0.3mm, Therefore, in order to ensure that the metal shell 92 cannot contact the first contact 44, the thickness of the front end of the rear section of the tongue 20 cannot be greater than 1.55 mm.

However, because the user does not insert it in a proper horizontal position, if the insertion angle is too large, the metal shell 92 of the USB3.0 male connector 99 will touch the first contact 44 during the insertion process, which will affect the design of the USB3.0 The factor of the maximum oblique insertion angle of the male head 99 is the horizontal distance d from the insertion end 35 of the positioning plane of the connection groove 31 and the first contact 44 of the first terminal 40, namely the height of the connection groove The smaller the c and the larger the horizontal distance d, the smaller the maximum bevel angle of the USB3.0 male connector 99 will be inserted, and the larger the distance e will be.

Please refer to FIG. 27, which is the twelfth embodiment of the present creation. It is roughly the same as the eleventh embodiment. The difference is that the insertion end of the positioning plane of the connecting groove 31 of this embodiment to the first connection of the first terminal 40 The horizontal distance of point 44 is short about 3.6mm, the USB3.0 male header 99 and the connection slot 31 are inserted into the horizontal position of the first contact 44 of the first terminal 40 at the maximum oblique angle, at this time the USB3. The angle x between the 0 male head 99 and the connecting groove 31 is about 24 degrees, and the distance e between the metal shell 92 and the first contact 44 on the tongue is still greater than 0.05 mm, which is still barely used without causing a short circuit.

Please refer to Figure 28, which is the thirteenth embodiment of this creation. It is roughly the same as the eleventh embodiment. The difference is that the thickness of the front end of the posterior segment of the tongue of this embodiment is increased by about 1.3mm and the height of the connecting groove c is also increased by about 6.2mm, when the USB3.0 male header 99 and the connecting slot 31 are inserted into the connecting slot at the maximum oblique angle to the horizontal position of the first contact 44 of the first terminal 40, then the USB3.0 male header 99 and the connecting slot The included angle x of 31 is about 16 degrees, and the distance e between the metal shell 92 and the first contact 44 on the tongue is still greater than 0.05 mm, which is still barely used without causing a short circuit.
