Description

Technical Field

[0001] The utility model relates to the related technical field, in particular to a shrapnel for a high-vibration connector. Background Technique

[0002] The electrical connection terminal is a kind of accessory product used to realize electrical connection, which is classified into the category of connectors in the industry, and its main function is to transmit electrical signals or conduct electricity. With the increasing degree of industrial automation and the increasingly strict and precise requirements of industrial control, the usage of electrical connection terminals is gradually increasing. With the development of the electronics industry, the application scope of electrical connection terminals is getting wider and wider, and the types are also increasing. In addition to PCB board terminals, the most widely used ones also include hardware terminals, nut terminals, spring terminals, etc. The hardware materials of electrical connection terminals are: copper, iron, alloy, zinc alloy, aluminum, steel, etc.

[0003] With the rapid development of high-voltage and high-current electrical connectors, most of the torsion spring jacks used in the current industry are spiral cylinders, and both ends are open for free assembly into the jack body. Since the free cylinder is formed by stamping and curling sheet metal and then twisting, the true roundness of the spiral cylinder is poor, and the parallelism of both end faces is poor, resulting in the inability to limit the axial position and achieve good contact and current sharing in the high-speed vibration environment of the vehicle. Therefore, ablation is likely to occur when the vehicle is running at high speed. Once ablation occurs, it will bring great potential safety hazards.

[0004] As disclosed in a new type of jack contact part with the patent number CN102157820B, in order to prevent jitter and poor contact, the length of the plug inserted into the connector head needs to be greater than the length of the torsion spring piece, so that the torsion spring piece can be pressed between the connector head and the connector at a relatively stable position. However, in actual use, the length of the connector head is not necessarily greater than the length of the torsion spring piece. In a high-frequency vibration environment, the contact part is prone to axial movement, resulting in poor contact and difficulty in current sharing, and ablation occurs. To solve the above problems, further improvement is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shrapnel for a high-vibration connector to overcome the deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A shrapnel for a high-vibration connector includes an integrally formed metal tubular body. The metal tubular body includes a pair of positioning rings and a plurality of flow guiding strips. The pair of positioning rings are fixedly arranged at the head and tail ends of the flow guiding strips, and the positioning rings are each provided with a clamping interface.

[0008] Further elaboration, the clamping interface is an L-shaped structure, and the end of the clamping interface also extends vertically outward to one side wall of the positioning ring.

[0009] Further elaboration is as follows. A plurality of diversion bars are arranged around the side wall of the positioning ring, and the ends of the plurality of diversion bars are fixedly connected to the positioning ring.

[0010] Further elaboration is as follows. The clamping interfaces provided on the diversion bars are used for clamping with the male connector and the female socket.

[0011] Further elaboration is as follows. Each of the pair of positioning rings is provided with a clamping interface, and the positioning rings are symmetrically arranged with the middle part of the diversion bar as the axis of symmetry.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model can be clamped to the inner side wall of the female socket. At the same time, when the male connector is inserted into the female socket, the male connector can also be clamped. After the male connector is inserted and rotated, the buckling is completed, and the male connector and the female socket can be tightened through the present utility model; effectively avoiding the axial displacement between the male connector and the female socket, so as to avoid poor contact, and being more suitable for some high-vibration environments, improving the connection reliability of the connection terminals.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality of", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0023] In this embodiment, the clamping interface 3 is an L-shaped structure, and the end of the clamping interface 3 also extends vertically outward from one side wall of the positioning ring 1. In this embodiment, it is used on some male connectors and female seats with clamping pins (pins or protrusions) provided on the side walls. The clamping pins can be clamped to the clamping interface 3 as the male connector or the female seat rotates, so that the male connector and the female seat can be clamped to the clamping interface 3 by the clamping pins and then complete the limiting and tightening.
