Description

TECHNICAL FIELD

[0001] The application relates to a socket connector. BACKGROUND

[0002] In the prior art, such as the patent disclosure scheme CN111864458A, the two side ears of the upper and lower iron shells 24 and 25 are generally welded to the mating circuit board after being directly stacked by a single sheet, and the structure is weak in strength when the connector is installed in the whole machine and abuts against the machine body structure, and is easily deformed to cause product installation shaking. It cannot be effectively and accurately positioned.

[0003] In order to increase the thickness direction structure of the ear, the outer iron shell can be designed as a powder metallurgy structure or a die casting structure, such as the prior art CN118431835A. However, other parts of the outer iron shell except the ear do not need such thick structure, and if the entire outer iron shell is designed as a powder metallurgy structure or a die casting structure, the overall size of the connector will be increased, especially the thickness and width of the entire connector. In addition, the powder metallurgy structure or the die casting structure itself has a higher manufacturing cost than the stamping part.

[0004] Therefore, it is necessary to design a new scheme to solve the above technical problems. CONTENT OF THE UTILITY MODEL
