Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a straight pin socket. Background Art

[0002] A connector is an electronic component used to connect wires or cables. It is one of the most common accessory products in the industry and is often used in electrical and electronic equipment. The main function of a connector is to provide a safe and reliable connection point for the transmission of current, signals or data. A connector usually consists of two parts: a plug and a socket, where the plug can be inserted into the socket to form an electrical connection.

[0003] The connector socket includes a socket shell and a pin, and the pin is inserted into the socket shell. When producing a straight pin socket, the socket shell is generally produced by injection molding, and then the pin is inserted into the socket shell. However, the straight pin socket produced in this way has poor air tightness and is difficult to meet the waterproof requirements of the straight pin socket. When facing a humid, water splashing environment, the straight pin socket is difficult to effectively prevent moisture from intruding, thereby affecting the normal operation of the internal pins and circuits, and even causing short circuits, damage and other consequences.

[0004] The above defects need to be solved urgently. Utility Model Content

[0006] The technical solution of the utility model is as follows:

[0007] A straight pin socket comprises a socket body and a plurality of straight pins. The socket body is formed by injection molding on the outside of the straight pins. The socket body comprises a first chamber and a second chamber which are arranged opposite to each other. One end of the straight pin passes through the first chamber and is accommodated in the second chamber. The bottom of the first chamber and the bottom of the second chamber both protrude outward to form a C-angle boss, and the C-angle boss surrounds the straight pins.

[0008] According to the above-mentioned solution of the utility model, the C-angle boss includes a plurality of inclined portions, and the angles formed between the inclined portions and the bottom of the first chamber and the bottom of the second chamber are acute angles.

[0010] According to the above-mentioned solution of the utility model, the barb includes a straight surface and an inclined surface, the straight surface is perpendicular to the central axis of the socket body, and the inclined surface is inclined in the direction of the straight pin away from the first cavity.

[0011] According to the above-mentioned solution of the utility model, a step is provided on the straight pin, and the step is provided on a side of the barb close to the first chamber, and at least a part of the step is provided in the insertion hole.

[0012] According to the above-mentioned solution of the utility model, the step includes an upper step and a lower step, the lower step is arranged in the insertion hole, a part of the upper step is arranged in the insertion hole, and the other part of the upper step is arranged in the chamber.

[0013] According to the above-mentioned solution of the utility model, the width of the lower step is greater than the width of the upper step.
