Description

A connector female jack

technical field

The utility model relates to the field of electrical connection components, in particular to a connector socket.

Background technique

In the connection of electrical equipment, connectors are indispensable. Traditional connectors often have a female head and a male head that is mated with the female head. The sockets of traditional connectors are generally made of copper rods, which is time-consuming and laborious. , the production cost is high and the time is long, especially the female head of the connector, which also involves drilling. For this reason, most of the female heads are processed in the form of plate bending to form a U-shaped section, but the female head of this structure often has the following Disadvantages, poor elasticity, easy to deform, long-term use will cause the female head to lose its elasticity, which will affect the effective contact area between the wood and the male head, cause local current to increase heat, and affect the safety performance of the connector.

Utility model content

Based on the above problems, the purpose of this utility model is to provide a connector female jack that is not easily deformed, has good elasticity, good contact effect, simple structure and smooth insertion.

In view of the above problems, the following technical solution is provided: a female connector socket, including a socket, the outer cylindrical wall at one end of the socket is provided with a welding cup for welding the power cord, and the socket is stamped from a plate It is rolled to form a hollow cylindrical structure in the middle. The diameter of the insert tube is slowly reduced relative to one end of the welding cup to form a close-up, and the diameter of the close-up end is enlarged to form a horn-shaped socket; the socket is provided with a A number of elastic grooves are opened to the rear of the closure, and the elastic grooves are evenly distributed along the radial direction of the insert.

In the above structure, the closure and the elastic groove can make the closure expand outward when the male head is inserted, and tightly contact with the male head to achieve good electrical contact. The horn-shaped socket can guide and position when the male head is inserted. Make the closing opening gradually open along the male head to avoid stagnation. After the elastic groove is set on the insert of the cylindrical structure, an arc-shaped cross section is formed between the elastic groove and the elastic groove. Compared with the U-shaped cross section with one side open, it has Stronger rigidity and elasticity can effectively improve the connection firmness and service life of the connector.

The utility model is further provided that the end of the insertion tube provided with the welding cup is a welding end, the diameter of the welding end is smaller than the diameter of the insertion tube, and the welding cup is set at the end of the welding end.

In the above structure, the diameter of the welding end is smaller than the diameter of the socket, and the step formed by the diameter difference facilitates the axial positioning of the socket when the socket is installed on the connector mounting seat.

The utility model is further provided that the outer cylindrical surface at the junction of the insertion sleeve and the welding end is provided with a positioning surface formed by a small extension toward one end of the mouth, and the positioning surfaces are two and are formed on the outer circular surface of the insertion sleeve. 180°relative setting.

In the above structure, the positioning surface facilitates the radial positioning of the insert when the insert is installed on the connector mounting seat. This positioning can ensure that the orientation of the solder cups is consistent, and it is convenient for welding the wires later.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

Referring to Fig. 1 and Fig. 2, a connector female jack as shown in Fig. 1 and Fig. 2 includes a socket 10, and the outer cylindrical wall at one end of the socket 10 is provided with a welding cup for welding a power cord 21. The insertion sleeve 10 is stamped and rolled from a plate to form a hollow cylindrical structure. The diameter of the insertion sleeve 10 is slowly reduced relative to the end of the welding cup 21 to form a neck 11, and the diameter of the end of the neck 11 is enlarged to form a trumpet shape. Socket port 12 ; the socket port 12 is provided with several elastic grooves 13 along its axial direction to the rear of the closing port 11 , and the elastic grooves 13 are evenly distributed along the radial direction of the socket 10 .

In the above structure, the closing port 11 and the elastic groove 13 can make the closing port 11 expand outward when the male plug is inserted, and tightly contact with the male plug to achieve good electrical contact. The horn-shaped socket 12 guides and positions when the male plug is inserted. At the same time, the closing mouth 11 can be gradually opened along the male head to avoid stagnation. After the elastic groove 13 is provided in the cylindrical socket 10, an arc-shaped cross section is formed between the elastic groove 13 and the elastic groove 13. Compared with The U-shaped section with an opening on one side has stronger rigidity and elasticity, which can effectively improve the connection firmness and service life of the connector.

In this embodiment, the end of the insert 10 provided with the welding cup 21 is the welding end 20 , the diameter of the welding end 20 is smaller than the diameter of the insert 10 , and the welding cup 21 is set at the end of the welding end 20 .

In the above structure, the diameter of the welding end 20 is smaller than that of the insert sleeve 10 , and the step formed by the diameter difference facilitates the axial positioning of the insert sleeve 10 when the insert sleeve 10 is mounted on the connector mounting seat.

In this embodiment, the outer cylindrical surface of the insert sleeve 10 at the junction with the welding end 20 is provided with a positioning surface 14 extending slightly toward one end of the mouth 11, and there are two positioning surfaces 14 on the insert sleeve 10. The outer circular surfaces are set relative to each other at 180°.

In the above structure, the positioning surface 14 is convenient for the radial positioning of the socket 10 when the socket 10 is installed on the connector mounting seat. This positioning can ensure that the direction of the welding cup 21 is consistent, which is convenient for welding wires in the later stage.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. These improvements and modifications should also be regarded as the protection scope of the present utility model.
