Nanometer type electronic card connector

Nanoelectronic card connector

The present invention relates to the field of connectors for mobile communication devices, and particularly relates to a nano-electronic card having a stable card insertion and card-removing function, and capable of exiting the electronic card without contacting the terminal with the electronic card, thereby effectively avoiding terminal damage. Connector.

Electronic cards are widely used in various electronic products, of which SIM cards are the most widely used electronic cards.

The SIM card is an abbreviation of (Subscriber Identity Module), also known as smart card, user identification card, and the GSM digital mobile phone must be equipped with this card. It stores the information of several mobile phone customers on a computer chip, the encrypted key and the user's phone book and other content, which can be authenticated by the GSM network user identity and encrypt the voice information of the customer's call.

At present, a nano-SIM card has appeared on the market. The nano-SIM card is called a nano-type SIM card, and is also called a fourth-form element integrated circuit board. It is a new generation mobile phone SIM card. It is smaller and thinner than the micro-SIM area being used. The nano-SIM card is aimed at replacing the micro-SIM installed on the mobile phone. Its smaller size will release space for increased memory and larger battery, which helps mobile phone manufacturers produce thinner and lighter products. Therefore, nano - SIM card is the trend of SIM card development.

At present, most of the card-receiving methods in the nano-SIM card connector adopt the Push-Push, the cover or the manual card. In the above manner, when the SIM card is taken, the terminals of the SIM card and the SIM card connector are still at the Direct contact status, if the user removes The angle of the SIM card is incorrect or the power is too large, which may cause damage to other components and affect the service life of the entire SIM card socket. In addition, such operation may easily cause the terminals of the SIM card connector to be improperly squeezed, and for a long time, The terminal of the SIM card connector will be deformed and damaged, and the SIM card will fail to be normally turned on with the SIM card connector.

In view of this, the inventors propose the following technical solutions.

After the card holder 5 carries the electronic card 6 into the card space, the card slot 51 on the side of the card holder 5 forms a stable snap-position relationship with the elastic arm 423. The electronic card 6 and the card holder 5 can be stably positioned in the card space; in addition, when the electronic card 6 and the card holder 5 exit the card space, the card slot 51 and the elastic arm 423 on the side of the card holder 5 are quickly released. The buckle positioning relationship enables the electronic card 6 and the card holder 5 to quickly insert and remove the card space, avoiding the phenomenon of bad card withdrawal, and avoiding damage of the signal terminal 31 or the switch terminal 32.

As shown in FIG. 6 and FIG. 7, the housing 2 is provided with a first stopping portion 201 and a second stopping portion 202 for preventing over-pushing or over-pressing of the push-pull triggering structure 4, and such a structure can effectively protect The entire electronic card connector prevents the electronic card connector from being damaged when the push-pull structure 4 is actuated to improve the life of the creation.

The housing 2 includes: an upper housing 21 and a lower housing 22 that cooperate with each other. The upper housing 21 is formed with a card protrusion and/or a recess for stable assembly on both sides thereof, and the lower housing 22 is formed on both sides thereof. The recesses and/or the cams of the upper housing 21 are matched with the recesses and/or the cams, so that the upper housing 21 and the lower housing 22 are fastened to form a stable assembly, and the periphery of the insulating seat 1 is covered, and the insulating seat is matched. 1 Forming the card space. The upper housing 21 is also formed with pins 212.

The upper housing 21 is provided with a shaft hole 211 for mounting the pivot 412 of the rotating lever 41. The upper housing 21 is provided with a first stopping portion 201 for preventing excessive rotation of the rotating lever 41 corresponding to a position of one end of the rotating lever 41 for resisting the electronic card; the upper housing 21 corresponds to the pushing A second stop portion 202 for preventing the push rod 42 from being pushed over is provided at a position of one end of the rod 42 for fitting with the rotary lever 41.

The first stopping portion 201 is a sliding hole for fitting the sliding portion 413 of the rotating rod 41 and for restricting excessive sliding of the sliding portion 413, wherein the sliding hole has an arc shape. The sliding portion 413 is a slider protruding from the outside of the body 411 , and the slider is engaged in the sliding hole as the first stopping portion 201 .

The second stopping portion 202 formed in the upper casing 21 is a card, and the card and the side wall of the casing 2 form a limiting space for the second engaging portion 425 of the end of the main body 421 of the push rod 42 to pass through.

As shown in FIG. 8-10, when the present invention is used, when the electronic card 6 is not inserted, the left switch terminal 321 and the right switch terminal 322 of the switch terminal 32 are not in contact, and the sliding portion 413 of the rotary lever 41 is One end is exposed and protrudes from the card space.

The electronic card 6 is placed in the card holder 5, and the card holder 5 is pushed into the card space formed between the insulating seat 1 and the housing 2. When the card holder 5 reaches the end of the card space, the rotating rod 41 is first used. One end of the middle sliding portion 413 is in contact with each other, and as the vehicle is continuously pushed, the card holder 5 and the right switch terminal 322 are in contact with each other, and the right switch terminal 322 is pressed against the left switch terminal 321 and is turned on.

At the same time, the rotating lever 41 rotates clockwise to move the push rod 42 in a direction opposite to the direction in which the deck advances. During the rotation of the rotating lever 41, the sliding portion 413 of the rotating lever 41 can only slide in the sliding hole as the first stopping portion 201, so that the sliding portion 413 of the rotating lever 41 can be effectively prevented from excessively rotating, and the present invention can be protected. Parts in the creation. When the sliding portion 413 of the rotating rod 41 slides to the end of the sliding hole, the elastic arm 423 formed on the push rod 42 is engaged in the slot 51 on the side of the card holder 5, so that the electronic card 6 and the card holder 5 are positioned in the In the card space.

As shown in FIG. 11, when the card is retracted, a rod body 7 is provided, and the rod body 7 is passed through the through hole 55 in the card holder 5, so that the rod body 7 and the stopper portion 424 in the push rod 42 interfere with each other. The rod body 7 is pushed in the same direction as the pushing direction of the deck 5, and the push rod 42 is moved in the same direction as the pushing direction of the deck 5, and the card slot 51 and the elastic arm 423 on the side of the card holder 5 are quickly released from the stable buckle. In the positioning relationship, the push rod 42 pushes the rotating rod 41 to rotate the rotating rod 41 counterclockwise, and one end of the sliding portion 413 of the rotating rod 41 pushes the card holder 5, so that the card holder 5 and the electronic card 6 exit the card space. At this time, the right switch terminal 322 of the switch terminal 32 is reset, so that the left switch terminal 321 and the right switch terminal 322 are not in contact. During the pushing of the push rod 42 described above, when the sliding portion 413 of the rotating rod 41 slides to the front end of the sliding hole, the rolled portion 422 of the push rod 42 collides with the card as the second stopping portion 202, so that the push rod 42 Stopping, this effectively prevents the pusher 42 from over-pushing and protects the components in the creation.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and modifications made to the above embodiments in accordance with the technical essence of the present invention are still It belongs to the scope of this creative technical solution.
