Description

Technical Field

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

[0002] A vertical connector is a connector that is fixed upright on a circuit board. It consists of a connector socket and a connector plug that mates with the connector socket. Traditional connector socket structures, such as Fig.10 As shown, the front card slot and the side guide slot are both open structures. Now, many PCB boards are usually injected with waterproof glue on the surface to wrap the entire connector socket to achieve waterproofness. When injecting glue in the traditional open structure, the water glue will enter the socket shell, making the product unable to be plugged in and out. In addition: Since the connector is fixed upright on the circuit board for plugging and unplugging, higher requirements are also placed on the connection strength between the connector socket and the PCB board. Since the side of the traditional connector socket is grooved, its strength is greatly reduced, and there is no structure to strengthen the connection between the bottom and the PCB board, which can easily cause the connector socket to loosen during plugging and unplugging. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a vertical connector with good sealing performance and high connection strength.

[0004] In order to solve the above problems, the technical solutions adopted by the utility model include:

[0005] A vertical socket housing, with a bottom plate for supporting a PCB board at the lower end and a plug-in cavity at the upper end, an inner buckle plate at one side of the plug-in cavity, and snap-in grooves at both sides of the inner buckle plate;

[0006] The pin terminal is riveted on the bottom plate of the vertical socket housing, with the upper end placed in the plug-in cavity and the lower end extending out of the bottom plate for connection with the PCB board;

[0007] The plug housing is plugged into the plug-in cavity of the vertical socket housing, and the upper end surface is provided with a buckle connected to the card slot, the front end surface is provided with a pin socket for inserting the pin terminal, and the rear end is provided with a female terminal installation cavity connected to the pin socket.

[0008] The vertical connector is characterized in that a group of glue filling grooves arranged in a grid are provided on the lower end surface of the bottom plate.

[0009] The vertical connector is characterized in that the front ends of the pin terminals on at least two sides are provided with bending portions.

[0010] The vertical connector is characterized in that a reinforcing rib is provided between the middle of the inner buckle plate and the vertical socket housing.

[0011] The vertical connector is characterized in that a positioning groove is provided on the bottom plate of the vertical socket housing away from the inner buckle plate, and a positioning protrusion is provided at the front end of the plug housing to fit with the positioning groove.

[0012] The vertical connector is characterized in that the engaging groove is R-shaped, including a vertical surface, an inclined surface and an arc groove.

[0013] The vertical connector is characterized in that a concave portion and a convex portion are provided in the middle of the pin terminal, and the concave portion and the convex portion are riveted into the bottom plate of the vertical socket housing.

[0014] The vertical connector is characterized in that a flange is provided at the rear end of the plug housing.

[0015] The vertical connector is characterized in that the top of the plug-in cavity of the vertical socket housing is provided with a chamfer.

[0016] The advantages of the vertical connector of the utility model are as follows: 1. The vertical socket housing is connected to the end face of the plug housing by the snap connection groove on the inner buckle plate, so that the vertical socket housing forms a closed structure, which not only prevents water glue from entering the interior, but also greatly improves the strength of the housing; 2. By arranging a plurality of strengthening connection structures (such as glue filling grooves and the bending part of the pin terminal) at the bottom of the vertical socket housing, the vertical socket housing can be more firmly attached to the surface of the PCB board to improve the connection strength.
