Description

[Technical field]

[0001] The invention discloses a card edge connector. [Background technology]

[0002] For related known technologies, please refer to a card edge connector announced in Chinese utility model patent CN204045778U, wherein the card edge connector includes a longitudinal insulating body, a plurality of conductive terminals accommodated in the insulating body, and a locking mechanism installed on one side of the insulating body, wherein the insulating body is provided with a central slot for accommodating an electronic card from the upper end surface, and the locking mechanism includes a base and a lever portion extending upward from both sides of the base, a receiving groove for accommodating the electronic card and a stopping portion located in the receiving groove for locking the electronic card are provided between the two lever portions, a holding portion extends outwardly from the end of the insulating body, and the locking mechanism is installed on the holding portion, the holding portion includes opposite side walls and a clamping space located between the side walls, and the locking mechanism is provided with a ejection portion extending from the base and accommodated in the clamping space for repelling the electronic card. It can be seen that the card locking mechanism has lever parts on both sides of the base, which are used to rotate the card locking mechanism so that the ejection part pushes back the electronic card. However, when the electronic card in use blocks the lever part, it is difficult for the user to apply force to the lever part, and the card locking mechanism cannot release the electronic card.

[0003] Therefore, it is necessary to provide an improved card edge connector to solve the above problems. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to provide a card edge connector to ensure that the top card is stressed and releases the electronic card.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a card edge connector, comprising a longitudinal insulating body, a plurality of conductive terminals accommodated in the insulating body and a top clamp; the insulating body is provided with a slot for inserting an electronic card, the top clamp comprises a top clamp portion, a first pressing portion and a second pressing portion, the second pressing portion is fixed to the top surface of the first pressing portion, and force is applied to the first pressing portion or the second pressing portion, so that the top clamp portion can push out the electronic card.

[0006] Compared with the prior art, the present invention has the following beneficial effects: the top card is provided with a first pressing portion and a second pressing portion, which provides users with a variety of options and increases the pressing area. At the same time, the second pressing portion is arranged on the top surface of the first pressing portion, which saves space on one side of the electronic card to a certain extent.

[0020] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0021] Ginseng Figures 1 to 5 As shown, the present invention discloses a card edge connector 100, comprising a longitudinal insulating body 10, a plurality of conductive terminals 20 received in the insulating body 10, and a top clamp 30. The insulating body 10 is provided with a slot 11 for inserting an electronic card (not shown in the figure), and the top clamp 30 comprises a top clamp portion 31, a first pressing portion 32, and a second pressing portion 33. The second pressing portion 33 is fixed to the top surface of the first pressing portion 32. By applying force to the first pressing portion 32 or the second pressing portion 33, the top clamp portion 31 can be pushed out of the electronic card.

[0022] Ginseng Figures 1 to 3 As shown, the second pressing portion 33 extends through the top surface of the first pressing portion 32 and is inserted into the first pressing portion 32. The second pressing portion 33 includes a main body 330 extending away from the first pressing portion 32, a fixing portion 331 extending from one end of the main body 330, and a second pressing surface 336 extending from the other end. The fixing portion 331 is provided with a buckling portion 332. The first pressing portion 32 is formed with a limiting portion 320 that cooperates with the buckling portion 332. A pair of shoulders 333 are provided above the buckling portion 332. The first pressing portion 32 is formed with a step portion 321 that supports the shoulder 333. The buckling portion 332 includes a pair of elastic arms 334 and a second pressing surface 336 formed on the elastic arms 334. 4, the first pressing portion 32 is provided with a slide groove 322 for accommodating the elastic arm 334 and a retaining wall 323 cooperating with the snap protrusion 335, the limiting portion 320 includes a step portion 321, the slide groove 322 and the retaining wall 323, and when the second pressing portion 33 is inserted into the first pressing portion 32 from top to bottom, a pair of elastic arms 334 slide downward along the slide groove 322 until the shoulder 333 abuts against the step portion 321 and the snap protrusion 335 abuts against the retaining wall 323, at which time the second pressing portion 33 can be firmly fixed to the first pressing portion 32, so that when force is applied to the second pressing portion 33, the second pressing portion 33 will avoid falling off from the first pressing portion 32. The first pressing portion 32 has a first pressing surface 324, and the first pressing surface 324 is provided with a plurality of convex ribs 325 for the user to apply force. In the vertical direction, the projection of the first pressing surface 324 overlaps with the projection of the second pressing surface 336. On the side farthest from the electronic card, the side of the main body 330 can be set to be flush with the side of the first pressing portion 32 or adjacent to the side of the first pressing portion 32. Such a setting can avoid increasing the lateral space away from the electronic card to save space. In addition, the second pressing portion 33 can also be extended and formed integrally with the first pressing portion 32 (not shown in the figure).

[0023] Ginseng Figures 4 to 8 As shown, the top clamp 30 is pivotally connected to one longitudinal end of the insulating body 10. When a force is applied to the first pressing portion 32 or the second pressing portion 33, the top clamp 30 will rotate, and its top clamp portion 31 pushes upward to release the electronic card. The bottom of the top clamp 30 is provided with a stopper 35 extending downward. When the top clamp 30 rotates, the stopper 35 finally abuts against the insulating body 10, which can prevent the top clamp 30 from rotating excessively. From top to bottom, the top clamp 30 includes a first pressing portion 32, a body portion 34, and a top clamp portion 31 extending integrally. The top clamp also includes a second pressing portion 33 fixed to the first pressing portion 32. The stopper 35 can be provided at the bottom of the body portion 34 or the bottom of the top clamp portion 31. In addition, the bottom of the body portion 34 and the bottom of the top clamp portion 31 are both provided with a stopper 35 to realize a double blocking structure, effectively preventing the top clamp 30 from rotating excessively.

[0024] Ginseng Figures 9 and 10 As shown, the card edge connector 100 also includes a shielding member 40 covering the insulating body 10, the shielding member 40 is torn outward with a spring piece 41, the insulating body 10 is provided with a limiting groove 12 matching therewith, the spring piece 41 is stopped on the inner wall surface of the limiting groove 12, and the shielding member is fixed on the insulating body 10.

[0025] In summary, the above are only preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and the contents of the present invention should still fall within the scope of the present invention.
