Through set up with metal reinforcement A looks joint complex metal reinforcement B can effectively strengthen on the one hand the tower intensity prevents tower upper portion fracture, on the other hand can avoid plastic tower and plastic hasp directly to take place the joint contact again to can avoid plastic tower and plastic hasp to take place wearing and tearing, rupture phenomenon, further promote the stability of quality and the life of card edge connector product.

The connection relationship between the metal reinforcement B5 and the tower 11 and the metal reinforcement a4 is further described below. Preferably, a U-shaped positioning wall portion 1120 is formed on the outer side of the upper portion of each of the tower upper portions 112 by thinning;

each metal reinforcing piece B5 has a main body part 50 in a U-shape and two holding arm parts 51 in a vertical bar shape and connected to the outer side of the main body part 50 side by side, the main body part 50 is wrapped outside the U-shaped positioning wall part 1120, and the two holding arm parts 51 are respectively inserted into the upper tower part 112 in a close fit manner; in addition, a locking hole a52 is respectively disposed on the two holding arm portions 51 of each metal reinforcement B5, and the two locking holes a52 can be locked and connected to or separated from the two locking portions 40 on the lock catch 3.

Further, the structure that the main body portion 50 is wrapped outside the U-shaped positioning wall portion 1120 is: a retaining stop 1121 is disposed on each U-shaped positioning wall 1120; each main body portion 50 is composed of a main board and two side boards integrally connected to two opposite sides of the main board, a fastening hole B53 is disposed on the main board of each main body portion 50, and each fastening hole B53 can be sleeved on a corresponding retaining stop 1121.

The two holding arm parts 51 are respectively and integrally connected to a vertical side of the two side plates, which faces away from the main plate, and the two holding arm parts 51 are respectively inserted into the tower upper part 112 in a close-fitting manner in the following structure: a pair of slots 115 for tightly inserting the two holding arms 51 are respectively arranged on each of the upper portions 112 of the towers, and a concave pit is concavely arranged on the inner wall of each of the slots 115; correspondingly, a hook is formed on each of the holding arm portions 51 to engage with the concave recess.

In summary, the metal reinforcing parts a are embedded in the two latches, and the metal reinforcing parts B which are in clamping fit with the metal reinforcing parts a are positioned on the outer sides of the upper parts of the two towers, so that the strength of the latches and the towers can be effectively enhanced, the phenomena of abrasion, breakage and the like of the latches and the towers can be avoided, and the quality stability and the service life of the whole card edge connector product can be greatly improved.

The above description is only a preferred embodiment of the present invention, but not intended to limit the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as within the protective scope of the present invention.
