Referring to the first figure, the card edge connector 100 of the present invention is used for plugging an electronic card (not shown). The card edge connector 100 includes a longitudinally-shaped insulating body 1 extending in the longitudinal direction, a plurality of conductive terminals 2 received in the insulative housing 1 , and a locking mechanism 3 mounted on the end portion 11 provided at one end of the insulative housing 1 .

As shown in the second to fourth embodiments, the insulative housing 1 includes two opposite side walls 12 and a vertically long central slot formed between the two side walls 12 for plugging in an electronic card (not shown). 13. The central slot 13 defines a longitudinal direction, and the end portion 11 is recessed with a mounting slot 111. The latch mechanism 3 includes a main body portion that is fixed in the mounting slot 111 and disposed in a lateral direction perpendicular to the longitudinal direction. And an ear button 32 extending in the longitudinal direction of the main body portion 31. The ear button 32 includes an elastic buckle portion 321 of a lock electronic card (not shown) and a side of the elastic buckle portion 321 for preventing the elastic buckle portion 321 The elastic support portion 322 that is excessively deformed. The mounting groove 111 extends through the upper and lower surfaces of the insulative housing 1. The lateral sides of the mounting slot 111 are provided with a step portion 112 communicating with the mounting slot 111. The main body portion 31 includes a base portion 311 and two ends of the base portion 311. The first buckle arm 312 and the second buckle arm 313 of the side, the step portion 112 erects the first buckle arm 312 and the second buckle arm 313 upward to restrict the downward movement of the main body portion 31. In order to prevent the locking mechanism 3 from being fixed to the end portion 11 and moving upward, the main body portion 31 is provided with a pulling arm 33, and the pulling arm 33 is arranged in a plate shape. Of course, the pulling arm 33 can also be set in other forms. The end portion 11 is provided with an end wall 133 outside the mounting groove 111. The end wall 133 is provided with a stopping portion 1130 for stopping the upward movement of the pulling arm 33. The pulling arm 33 protrudes from the end wall 133. The pulling arm 33 is operated to control the fixing and disengaging between the locking mechanism 3 and the end portion 11.

Specifically, a first protruding portion 14 is respectively disposed on two lateral sides of the mounting groove 111, and the step portion 112 is concavely formed at an upper end of the first protruding portion 14, and the end wall 133 includes two first protruding portions. The lateral width of the longitudinal direction of the portion 14 is greater than the second protrusion 1331 and the third protrusion 1332 of the first protrusion 14 , and the base 311 , the first buckle arm 312 and the second buckle arm 313 are clamped in the lateral direction. The first protruding portion 14 is sandwiched between the first protruding portion 14 and the second protruding portion 1331 and the third protruding portion 1332 in the longitudinal direction, thereby realizing the locking mechanism 3 in the longitudinal and lateral directions. Limits. The triggering arm 33 protrudes from the second latching arm 313 in the longitudinal direction of the third protruding portion 1332. The blocking portion 1130 is a downwardly blocking end of the third protruding portion 1332 that blocks the pulling arm 33. Bump. The ear button 32 extends integrally from the first buckle arm 312 and the base portion 311, and the first buckle arm 312 and the second buckle arm 313 form a compartment 314, and the compartment 314 is configured to provide the The buckle arm 312 and the second buckle arm 313 are elastically deformed. When the ear button 32 or the lever arm 33 is pulled in the lateral direction, the ear button 32 connected to the first buckle arm 312 and the second buckle arm are connected to the second buckle arm. The trigger arm 33 of the 313 can also be elastically deformed, so that the break of the ear button 32 and the pulling arm 33 can be effectively avoided. Further, the pulling arm 33 is provided with a guiding surface for guiding it into the stopping portion 1130, so that the resistance generated by the pulling arm 33 during the fastening of the blocking portion 1130 can be effectively reduced.

The first thickening portion 3111 and the second thickening portion 3112 are respectively protruded from the lateral sides of the base portion 311, and the first thickening portion 3111 and the second thickening portion 3112 are respectively protruded from the lateral sides of the base portion 311. The second thickened portion 3112 is sandwiched between the second protruding portion 1331 and the third protruding portion 1332 in the lateral direction. The first thickening portion 3111 extends upward to the first fastening arm 312, and the ear button 32 extends outwardly from the first thickening portion 3111. The lateral width of the first thickening portion 3111 is smaller than the ear. The buckle 32 and the longitudinal thickness of the first thickening portion 3111 are equal to the second protruding portion 1331, and thus, the second protruding portion 1332 can be clamped between the ear buckle 32 and the main body portion 31 in the longitudinal direction.

The method of attaching and detaching between the lock mechanism 3 and the insulative housing 1 will be described with reference to the fifth figure. The first locking arm 312 and the second fastening arm 313 are erected on the step portion 112. Upper, the pulling arm 33 passes over the stopping portion 1130, and then the pulling arm 33 is released to be engaged into the blocking portion 1130, finally to achieve the mounting of the locking mechanism 3. The dismounting of the locking mechanism 3 firstly presses the pulling arm 33 away from the stopping portion 1130, and then the main body portion 31 is pulled upwards out of the mounting groove 111, thereby finally disassembling the locking mechanism 3.

In view of 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 of the present invention. Therefore, the scope of the present invention should not be limited by the scope of the invention, and all the equivalent equivalents and modifications of the present invention are intended to be included within the scope of the following claims.
