Description

Technical Field

[0001] The utility model belongs to the field of connectors, and in particular relates to a connector component. Background Art

[0002] The M.2 connector is mainly used to expand and upgrade the performance of the computer. It can be connected to a solid-state drive, Bluetooth module, or WIFI module. As the capacity of the hard drive increases and the transmission speed increases, the heat generated also increases. In order to dissipate heat quickly, a heat sink is usually installed on the solid-state drive, and the heat sink needs to be tightened with screws.

[0003] Chinese patent CN116799542A discloses a card edge connector, which includes an insulating body and a conductive terminal fixed to the insulating body. The insulating body includes a front face and a rear face opposite to each other, a top face between the front face and the rear face, and a slot extending forward through the front face. The conductive terminal includes a contact portion extending into the slot, a retaining portion retained by the insulating body, and a welding foot. The card edge connector further includes a plate and a locking member fixed to the top of the insulating body. The locking member has a threaded hole extending upward. The plate is provided with an opening corresponding to the threaded hole of the locking member. The plate limits the upward movement of the locking member, and the plate is buried in the insulating body. The plate is bent downward from its front edge to form a front plate, and the two ends of the front plate are buried in the insulating body, and the remaining parts are exposed outside the insulating body. The plate is provided with side plates that are bent downward and extended at both ends, and the plate and the side plates are both buried in the insulating body. The side plate extends downward from its bottom edge out of the bottom surface of the insulating body to form a pin. Each side plate is provided with two spaced pins at front and back. The card edge connector comprises a rear plate covering the rear end surface of the insulating body. The rear plate has fixing ears bent inwards from both ends thereof and embedded in the insulating body.

[0004] When the above-mentioned card edge connector is used to install the radiator, one end of the radiator is fixed to the locking piece of the above-mentioned card edge connector by screws, and the other end of the radiator is fixed to the PCB board by studs and then fixed by screws. Since the plate with openings of the above-mentioned card edge connector is buried in the insulating body, and it is necessary to add a locking piece with threaded holes to lock one end of the radiator, the manufacturing process steps are increased, and the manufacturing cost is increased. In addition, the above-mentioned card edge connector only has pins on the side panels on both sides, and the back panel is not provided with pins connected to the PCB board. Therefore, there are problems such as loose connection with the PCB board, insufficient connection strength and poor shielding effect. Therefore, it needs to be improved. Utility Model Content
