Card connector

Card connector

This creation provides a card connector, especially the improvement of the card ejection mechanism of the card connector.

With the innovation and progress of the technological age, various electronic products such as computers, mobile phones, digital cameras, digital camcorders, digital recorders, etc. have tended to multi-functional design patterns, and electronic products must remember the data or For static and dynamic audio and video data, there will be a card connector inside, which can be plugged into an electronic card (memory card) for recording and memory. Todays electronic products are developing towards light, thin, short, and small. Therefore, memory cards and card connectors have become smaller and smaller. In order to facilitate the insertion or ejection of memory cards into or out of the card connector slots, they The card connector is equipped with a card ejection device to guide the memory card to insert or eject the card connector. However, because the card ejection device is pushed by the spring, the memory card is pushed out of the card connector with the spring force when the card is ejected. However, due to the excessive elasticity of the spring, the memory card may be ejected from the card connector, causing damage or loss of the memory card; in addition, the electronic card may fly out of the card connector due to the failure of the card connector, causing the electronic card to be damaged Or missing, so an improved electronic card connector is needed.

In order to overcome the aforementioned shortcomings, the creator improved the card ejection mechanism of the card connector. For example, in the Republic of China New Patent Announcement No. M367466, an elastic piece is provided on the side of the card eject mechanism close to the card. The elastic piece abuts against the recess or protrusion of the electronic card. When the electronic card is withdrawn outward, the elastic piece acts on the recess of the electronic card. Or protruding to prevent the electronic card from flying out of the card connector suddenly. However, the force of the spring of the card connector ejecting mechanism is relatively large, and the elastic sheet may be deformed due to the relatively large force of the electronic card, and the electronic card may fly out, that is, the function of preventing the electronic card from flying out cannot be realized.

In summary, it is indeed necessary to provide an improved card connector to ensure that the electronic card will not fly out of the card connector.

The main purpose of this creation is to provide a card connector whose card eject mechanism can prevent electronic cards from flying out of the card connector.

In order to achieve the foregoing objective, this creation adopts the following technical solutions: a card connector, including: a main body, a housing, a terminal, and a card eject mechanism; The space is matched with the electronic card; the main body is provided with a groove on one side of the accommodating space along the front and rear direction, and an abutting block is provided at the rear end of the groove on the side close to the accommodating space; The spring, the slider, the clamping terminal, and the linkage rod. The slider is provided with a heart-shaped groove that cooperates with the linkage rod and the first spring to realize cyclic pressing. One end of the clamping terminal is a holding section that is fixed to the slider, and the other end extends to form an actuator Section, the actuating section includes a card abutting section for holding the electronic card, a sliding section for guiding the insertion of the electronic card, and a contact part that abuts on the abutment block to prevent the deflection of the clamping terminal when the card is flying.

Compared with the prior art, when the card connector of this invention is normally withdrawn from the electronic card, there is a gap between the contact part of the clamping terminal and the abutting block, allowing the clamping terminal to deflect and release the electronic card. When the electronic card is flying, The sliding block moves backward for a relatively large distance, and the contact portion of the clamping terminal abuts against the abutting block, so that the clamping terminal cannot be deflected and the electronic card is prevented from flying out.

The width of the second opening 2205 is smaller than the diameter of the second slot 2202, and the second spring 246 (detailed later) is installed. After entering, prevent it from jumping upwards. The width of the third channel 2203 is smaller than the diameter of the second channel 2202, a front baffle wall 2204 is formed at the junction of the second and third channels 2202 and 2203; the rear end of the second channel 2202 is provided with a first The opening 2206 is for the installation of the second spring 246 (detailed later). A positioning slit 2251 is provided on one surface of the first opening 2206, and the setting sheet 2252 is inserted therein, that is, passing through the common joint of the front blocking wall 2204 and the positioning sheet 2252 The function realizes the positioning of the second spring 246 in the front and rear of the second channel 2202. An abutting block 222 is provided at the rear end of the side of the channel of the main body 2. In a preferred embodiment, the abutting block 222 can be coated with a metal covering sheet 223 on the outside to enhance its strength.

The card ejecting mechanism 24 includes a first spring 241, a sliding block 242, a clamping terminal 243, a linkage rod 244, and a second spring 246. The first spring 241 abuts against the front wall 23 of the main body 2, and the other end abuts against the slider 242. One end of the clamping terminal 243 is a holding section 2431, which is held on the slider 242. The holding section 2431 extends backward to form a substantially U-shaped actuating section 2437. The holding section 2431 and the actuating section 2437 are connected by a connecting section 2432. The actuating section 2437 includes an abutting section 2433, a sliding section 2434, and an abutting section 2436. The card abutment section 2433 is substantially perpendicular to the insertion and removal direction of the card, abuts against the corresponding recessed part of the electronic card, and can hold the electronic card; the sliding connection section 2434 is substantially along the card insertion and removal direction backward from the card abutment section 2433 It extends obliquely and can guide card insertion; the abutment section 2436 extends from the sliding section 2434 to a direction opposite to the accommodating space 10, and the bending corner of the abutment section 2436 and the sliding section 2434 is a contact portion 2435.

The sliding block 242 is slidable along the electronic card insertion and removal direction, and mainly includes a thicker first main body portion 2426 and a thinner second main body portion 2425. The sliding block 242 is provided with a heart-shaped groove 2424. One end of the linkage rod 244 can slide in the heart-shaped groove 2424, and the other end is rotatably received in the main body 2. The push-push operation principle is well known in the industry and will not be repeated here. . The first main body portion 2426 is arranged at the front end, and the second main body portion 2425 is arranged at the rear end of the first main body portion 2426. The first main body portion 2426 can receive and fix the holding section 2431 of the clamping terminal 243, and the second main body portion 2425 is opposite to The first main body portion 2426 is arranged on the upper side. When the slider 242 is installed to the main body 2, a flat space for accommodating the clamping terminals 243 is formed between the second main body portion 2425 and the main body 2 for normal elasticity of the clamping terminals 243 therein. It deflects and prevents the clamping terminal 243 from rotating axially in the card insertion and removal direction. The first main body 2426 extends into the accommodating space 10 to form a card abutment protrusion 2421, which abuts against the card abutment protrusion 2421 when the electronic card is inserted and drives the card ejection mechanism 24 to act. When the electronic card is withdrawn, the card abutment protrusion 2421 pushes The electronic card is withdrawn outwards. The width of the rear end of the second main body portion 2425 is small, and the rear end is provided with a jack block 2423. The width of the jack block 2423 is smaller than the width of the third channel 2203. Road 2202 slides. The second spring 246 is accommodated in the second channel 2202, the diameter of the second spring 246 is greater than the width of the third channel 2203, the width of the third channel 2203 is smaller than the diameter of the second channel 2202, the second spring 246 The front end abuts against the front baffle wall 2204 of the second channel 2202, and the rear end abuts against the positioning piece 2252.

In normal use, when the electronic card is ejected, the force of the first spring 241 on the slider 242 is relatively small, and the slider 242 is abutted by the second spring 246 to avoid further sliding forward. There is a gap between the contact portion 2435 of the terminal 243 and the abutment block 222 of the main body 2, which can allow the clamping terminal 243 to deflect to the other side of the receiving space 10, thereby allowing the operator to pull out the electronic card. When the electronic card is accidentally ejected due to the situation, the momentary force of the first spring 241 on the slider 242 is relatively large, and the slider 242 abuts against the second spring 246 to shorten the second spring 246, that is, the entire card ejecting mechanism 24 moves backward. The moving distance of the end is relatively large. In this case, the contact portion 2435 of the clamping terminal 243 will abut against the abutting block 222 of the body 2, and friction between the two will prevent the clamping terminal 243 from moving to the other side of the receiving space 10. If one side deflects, the card abutting section 2433 of the clamping terminal 243 always abuts against the corresponding recess of the card, preventing the card from flying out, and avoiding the phenomenon of electronic cards flying away.

In this embodiment, the second spring 246 is accommodated in the second channel 2202, the opening width of the upper end of the second channel 2202 is smaller than its diameter, and the second spring 246 is fixed by the front and rear blocking members. In other embodiments, the width of the upper opening of the second channel 2202 may be increased to be greater than or equal to its diameter, and a blocking member may be added above to achieve positioning, and the front and rear directions are integrally formed with the main body 2.

In a preferred embodiment, a second spring 246 and a corresponding component holding the second spring 246 are provided in the second channel 2202. In other embodiments, the second spring 246 and its components can also be removed, and only an abutting block 222 is provided on the side of the rear end of the channel close to the receiving space 10. When the card ejecting mechanism 24 normally ejects the card, the operator's hand will abut the electronic card and then act on the slider 242. There is a gap between the contact portion 2435 and the abutment block 222, and the clamping terminal 243 can be moved away from the receiving space 10 Deflection of the direction. When the electronic card flies out, the slider 242 slides a large distance backwards, the contact portion 2435 of the clamping terminal 243 abuts against the abutting block 222, and the clamping terminal 243 is prevented from deflecting away from the receiving space 10 and still maintains The lock buckle of the electronic card realizes the effect of anti-flying card.
