Description

Waterproof socket connector

technical field

The utility model relates to a socket connector, in particular to a waterproof socket connector.

Background technique

Generally, the socket connector generally includes an insulating body, several conductive terminals fixedly installed in the insulating body, and a metal shell covering the insulating body. Due to the increasingly high requirements of end customers for product quality and performance, the waterproof function of electronic products has gradually been included as one of the important indicators. At present, most of the waterproof technology of electronic products adopts a soft rubber sealing ring with a roughly circular cross-section. On the socket connector, and the product shell compresses the sealing ring to deform it, so that the sealing ring sticks to the socket connector, so as to achieve the purpose of sealing and waterproofing.

However, since the deformation form of the sealing ring is very unstable, it is easy to cause one-sided deviation, so it is difficult to achieve a high waterproof level.

In order to achieve the above purpose, the waterproof socket connector provided by the utility model includes an insulating body, a metal shell covering the insulating body, several conductive terminals held in the insulating body, and a plurality of conductive terminals installed in the insulating body. It is used to buckle the fixing part of the mating plug connector. The insulating body includes a receiving cavity surrounded by a top wall, three side walls and a bottom wall, an opening, and a socket protruding from the side wall opposite to the opening to the receiving cavity. The fixing part includes two positioning pieces and a locking piece. The metal shell has a through accommodating space surrounded by a top board, a bottom board and two side boards for accommodating the insulating body. The waterproof receptacle connector also includes a first metal connection plate and a second metal connection plate with stepped peripheral edges, and the top wall and the bottom wall of the insulating body are respectively provided with first through holes that communicate with the receiving cavity. groove and a second through groove, the periphery of the first through groove is also stepped, and the first metal connection plate and the second metal connection plate are installed in the first through groove and the second through groove respectively Inside, and through the sealing fit of the stepped periphery, the two opposite side walls of the insulating body are respectively provided with grooves. There is a through hole in the middle of each of the locating parts, and a baffle plate is bent and extended outward from one edge of the through hole. The plates are in close contact with the side plates of the metal housing. The top plate of the metal shell is in close contact with the first metal connecting plate, the locking member is fixed on the bottom wall of the insulating body and fits to support the second metal connecting plate, and the metal shell The bottom plate is closely attached to the locking member.

As mentioned above, since the hole in the insulating body of the waterproof socket connector of the present invention is small, and the outer part of the insulating body is tightly fitted with a metal shell, dust and water can be effectively prevented from entering the connector. In addition, since the first metal connecting plate is in concave-convex fit with the through groove of the insulating body, the fit gap can be reduced to prevent water vapor from entering. Furthermore, since the parts that are in contact with the mating plug connector are two metal connecting plates, the friction between the mating plug connector and the insulating body can be reduced, thereby providing a good plugging force.
