Electric connection plug bush structure and electric connection device

Abstract

The invention relates to an electric connection plug bush structure and an electric connection device. The electric connection plug bush structure comprises a conductive main elastic body (2), plug-in gaps are formed in the main elastic body (2), and plug pins (4) of a plug can be inserted in the plug-in gaps in a connected mode. The electric connection plug bush structure further comprises a shell (1) and an auxiliary elastic body (3), a hollow cavity is formed in the shell (1), at least parts of structures of the main elastic body (2) and the auxiliary elastic body (3) are arranged in the hollow cavity of the shell (1), and the auxiliary elastic body (3) can abut against the main elastic body (2) in the direction pointing to the plug-in gaps. By means of the electric connection plug bush structure, the shell and the auxiliary elastic body are arranged for increasing clamping force applied by the main elastic body of the electric connection plug bush structure to the plug pins, the contact areas between the main elastic body and the plug pins are further increased, the contact resistance is reduced, the electrical connection between the main elastic body and the plug pins is more reliable and safer, and the service life of the electrical connection is prolonged.

Description

technical field [0001] The invention relates to an electrical connection device, in particular to an electrical connection socket structure and the electrical connection device. Background technique [0002] The principle of the existing power socket is to use the shrapnel of the socket to clamp the pin of the plug to complete the process of power transfer. Among them, the clamping form and clamping force of the socket in the power socket are the main factors affecting the service life and reliability of the power socket. [0003] The existing socket structure mainly depends on the bolt inserted into the socket, and then relies on the resilience of the socket itself to clamp the bolt. The clamping form is Figure 1A , 1B The point shown touches A, or Figure 2A , 2B The wire shown touches B. Since these two clamping forms are faced with the problem of high contact resistance caused by the insufficient resilience of the socket itself and the small contact area, it is easy...

AI Technical Summary

Problems solved by technology

Both of these two clamping forms face the problem of large contact resistance due to insufficient resilience of the socket itself and small contact area, so it is easy to cause heat when it is powered on, which affects the stability and reliability of the electrical connection. sex, and even a fire hazard

At the same time, the ignition at the moment of contact between the plug and the socket and the arcing at the moment of disconnection will also affect the electrical life of the electrical connection, affecting personal and property safety

[0004] For this problem, there is currently a design that increases the clamping force of the socket, so that the increase in the clamping force makes it difficult to insert and pull out the plug, and frequent insertion and extraction of the plug will also cause excessive wear of the socket, resulting in a decrease in the elasticity of the shrapnel itself. Small or even disappear, and then form poor contact and other problems that affect the stability and reliability of electrical connections
