As shown in fig. 1, the present embodiment provides a card edge connector and a snap structure thereof. The card edge connector 1 is used for inserting a memory card 2 (such as a random access memory (DDR 5) and the like), and at least one side of the memory card 2 is provided with a fastening edge 21. The card edge connector includes an insulative housing 10, a plurality of terminals 11 disposed on the insulative housing 10, and a movable latch arm 12 and a latch arm 13.

With continued reference to fig. 1 and 2, the insulative housing 10 has a base 100 disposed along the gold finger portion 20 of the memory card 2, and a first arm 101 and a second arm 102 disposed on opposite sides of the base 100. Preferably, the base 100, the first arm 101 and the second arm 102 form a "U" shaped structure. The base 100 is provided with a slot 100a into which the gold finger 20 of the memory card 2 is inserted, and the terminals 11 are distributed in the slot 100 a. So that the gold finger portion 20 can be electrically connected to each terminal 11 after being inserted into the slot 100 a. Each terminal 11 extends from the slot 100a to the lower part of the base 100, and can be soldered to the conductive portion 30 on the circuit board 3.

Continuously, the movable latch arm 12 is disposed on the first arm 101 of the insulating housing 10 for latching on the latch edge 21 of the memory card 2; and the memory card 2 inserted on the card edge connector 1 can be pushed upwards by pulling by hands, so that the memory card 2 can be pulled up. In addition, the snap spring arm 13 is disposed in the second arm 102 of the insulating housing 10 for being resiliently snapped on the other side of the snap edge 21 of the memory card 2.

Specifically, as shown in fig. 2, 3 and 4, the card edge connector 1 provided in this embodiment mainly uses the latch arm 13 to provide the force and space required for the elastic latch on the other side of the memory card 2, so as to reduce the moving space required for inserting and pulling the memory card 2. The second arm 102 of the insulating body 10 is provided with a slot 102a at a side adjacent to the base 100, the slot 102a is communicated with the inside of the second arm 102, and an assembling hole 102b communicated with the inner space of the second arm 102 is provided below the second arm 102, so that the snap spring arm 13 can be placed in the second arm 102 through the assembling hole 102 b. The latch arm 13 is a latch structure of the card edge connector 1, and is formed by integrally stamping and bending a metal material (such as a metal sheet), and has a fixing portion 130 and an arm portion 131 bent from two sides of the fixing portion 130 and extending upward, and the fixing portion 130 extends downward to form a pin 130a for being fixed on the fixing hole 31 of the circuit board 3.

With continued reference to fig. 3, an insert 102c is disposed in the second arm 102, and when the snap spring arm 13 is placed in the second arm 102, the insert 102c can be sandwiched by the fixing portion 130 and the two arms 131. As shown in fig. 4, the fixing portion 130 may be provided with a supporting edge 130b protruding outward, and the supporting edge is supported against the second arm 102 in the opposite direction of the placing direction of the second arm 102. For example, a stop block 102d is protruded at a corresponding position in the second arm portion 102 to prevent the snap spring arm 13 from exiting the second arm portion 102. In addition, with continued reference to fig. 4, each of the two arm portions 131 extends upward to form an elastic arm 131a, and the two elastic arms 131a correspond to the card slot 102a of the second arm portion 102, so that when the memory card 2 is inserted, the fastening edge 21 on the corresponding side thereof can enter the card slot 102a and be fastened and positioned by the two elastic arms 131 a.

In summary, the card edge connector and the fastening structure thereof provided by the present embodiment can be obtained by the above-mentioned structural components.

Alternatively, as shown in fig. 5, when the memory card 2 is to be inserted into the card edge connector 1, the memory card 2 corresponding to the side fastening edge 21 of the second arm 102 can enter the card slot 102a of the second arm 102 from top to bottom, and the two elastic arms 131a are pushed away by the memory card 2, so as to facilitate the insertion of the memory card 2. Then, as shown in fig. 6, after the memory card 2 is continuously inserted, the two elastic arms 131a can fall into the buckling edge 21 to provide the buckling and positioning effects for the memory card 2; the memory card 2 is locked and positioned by the movable locking arm 12 corresponding to the side locking edge 21 of the first arm 101.

Therefore, by using the card edge connector and the fastening structure thereof provided in this embodiment, only one side of the card edge connector needs to be provided with the movable fastening arm 12, and the other side of the card edge connector needs to be provided with the fastening elastic arm 13, and the elastic arms 131a at the two sides of the fastening elastic arm 13 simultaneously fasten the fastening edge 21 at the side of the memory card 2, so that the elastic deformation or the deformation space required by the two elastic arms 131a can be shared, and the memory card 2 can be plugged and pulled out in a labor-saving manner. More importantly, the snap spring arm 13 has no exposed movable space when the memory card 2 is inserted and pulled out, so that the card edge connector 1 can be applied to occasions with more limited space.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
