Figure 5 is a partial cross-sectional view showing the combination of the insulative housing and the card locking mechanism of the card edge connector of the present invention.

The specific embodiment of the card edge connector of the present invention will be described in detail below with reference to the drawings.

Referring to the first and second figures, the card edge connector 100 of the present invention is used to plug the electronic card 200. The card edge connector 100 includes an insulative housing 1 extending longitudinally, a plurality of conductive terminals 2 received in the insulative housing 1 , and a locking mechanism 3 for locking the electronic card 200 mounted on one end of the insulative housing 1 .

Referring to the second and third figures, the insulative housing 1 includes two side walls 11 and 12 disposed opposite to each other, a slot 13 formed between the two side walls 11, 12 and a longitudinal end of the slot 13 End wall 14. The end wall 14 is provided with a mounting portion 141 for mounting the locking mechanism 3, and the mounting portion 141 is provided with a receiving groove 1411 for receiving the locking mechanism 3. Further, the mounting portion 141 includes a pair of first protrusions 142 protruding outward from the end wall 14 of the insulative housing 1 , and the receiving slots 1411 are formed between the two first protrusions 142 .

As shown in the fourth figure, the card locking mechanism 3 includes a main body portion 31 and a locking portion 32 extending from the main body portion 31 for locking the electronic card 200. The main body portion 31 of the locking mechanism 3 is received in the housing portion 31. The description is placed in the slot 1411. In order to prevent the locking mechanism 3 from being swayed in the up-and-down direction after being attached to the mounting portion 141, the main body portion 31 of the locking mechanism 3 is provided with a clamping portion 33 clamped on the mounting portion 141, wherein the clamping portion The portion 33 is sandwiched by the outer side of the first protruding portion 142. The end of the clamping portion 33 is provided with a hook portion 34. The outer portion of the first protruding portion 142 is provided with a convex portion 1421 for holding the hook portion 34. Preferably, the clamping portion 33 is disposed on opposite sides of the main body portion 31, and the clamping portion 33 is formed by bending downward from the upper end of the body portion 31. In order to prevent the main body portion 31 of the locking mechanism 3 from being swayed in the front and rear and longitudinal directions of the insulating body after being inserted into the receiving groove 1411, the first protruding portion 142 further protrudes with a width and a height greater than the first portion. a second protruding portion 143 of the protruding portion 142, and a limiting portion 1431 for blocking the main body portion 31 and the clamping portion 33 between the portion of the second protruding portion 143 that extends beyond the first protruding portion 142 and the first protruding portion 142, A limiting groove 144 for holding the main body portion 31 and the clamping portion 33 is formed between the end wall 14 and the second protruding portion 143. In order to better limit the sway of the locking mechanism 3 in the front-rear direction, the main body portion 31 protrudes in the longitudinal direction of the insulating body with a thickened portion 35 having a smaller width than the main body portion 31, and the thickness of the thickened portion 35 The second protruding portion 143 has an opposite inner wall 1432, and the outer side of the thickened portion 35 abuts against the inner wall 1432 of the second protruding portion 143 by the locking mechanism. The thickened portion 35 of the third portion achieves a secondary limit in the front-rear direction to better achieve the fixing of the lock mechanism 3.

Referring to the fourth and fifth figures in detail, the clamping portion 33 includes a resilient arm 331 extending upward from the upper end of the main body portion 31, a horizontal arm 332 extending outward from the elastic arm 331, and a horizontal arm 332 The lower extending clamping arm 333 can effectively block the elastic arm 331, the horizontal arm 332 and the clamping arm 333. The elastic arm 331, the horizontal arm 332 and the clamping arm 333 form a first U-shaped structure 334 with an opening downward, and the two elastic arms 331 form an opening U-shaped structure 335 at the upper end of the main body portion 31. The hook portion 34 is located at the end of the clamping arm 333. In order to facilitate the attachment and detachment of the locking mechanism 3, the locking mechanism 3 is replaced, and the locking mechanism 3 further extends from the clamping portion 33 with an operating portion 36 for operating and controlling the clamping portion 33. Specifically, the The operation portion 36 is an operation arm extending upward from the horizontal arm 332, and the operation arm is provided with a plurality of step portions 361 for increasing the frictional force and the touch feeling. The second U-shaped structure 335 with the opening between the two elastic arms 331 is used for giving the two elastic arms 331 a sufficient elastic deformation space when the user presses the operating arm. The operating arm is located above the horizontal arm 332 adjacent the abutment of the horizontal arm 332 and the clamping arm 333, which makes it easier to open the clamping arm 333 outward. The horizontal arm 332 is erected on the upper end of the first protrusion 142 and the upper end of the horizontal arm 332 is opposite to the insulative housing 1 after the lock mechanism 3 is mounted on the accommodating groove 1411 from the top. The upper end is flush.

In the above, the above is only a preferred embodiment of the present invention, and those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the invention.
