Short-circuit connector

Abstract

The invention belongs to the technical field of test plugs, and particularly discloses a short-circuit connector. The short-circuit connector comprises a connecting part, a plug-in and at least two fixing structures, wherein the connecting part is provided with a connecting port and a plurality of positioning grooves, and the connecting port is connected with a connector; a bent structure is annularly arranged on the inner wall of the connecting port, the connecting port and the bent structure jointly define a first waterproof groove, and a second waterproof groove is formed in the bottom of the first waterproof groove; and the connector is provided with a first plug-in matched with the first waterproof groove, the first plug-in is provided with a second inserting piece in a protruding mode, the first plug-in is inserted into the first waterproof groove, and the second plug-in is inserted into the second waterproof groove. A short-circuit terminal comprises insulating columns and contact pins which are connected, wherein the insulating columns are detachably inserted into the corresponding positioning grooves, and the contact pins can be inserted into a terminal box. The fixing structures are detachably installed on the connecting part, and the at least two fixing structures are oppositely arranged and abut against the corresponding insulating columns. Thus, the positioning precision and stability of the short-circuit terminal are improved, so the short-circuit connector has a good waterproof sealing effect.

Description

technical field [0001] The invention relates to the technical field of test plugs, in particular to a short-circuit connector. Background technique [0002] In the process of power production and testing, it is necessary to use short-circuit connectors to reliably short-circuit the circuit to ensure the safety of electrical equipment and personnel. [0003] The short-circuit terminals in the common short-circuit connectors are screwed and installed on the short-circuit connectors, and the stability and positioning accuracy are relatively poor. When the short-circuit terminal is plugged into the port of the external short-circuit box, when the short-circuit terminal and the short-circuit box collide or are affected by external forces, it is easy to rotate and move along its axial direction, and the positioning accuracy is poor, resulting in multiple short circuits. The length of the terminals protruding from the shorting connector is inconsistent, so that some of the shortin...

AI Technical Summary

Problems solved by technology

[0003] The short-circuit terminal in the common short-circuit connector is threaded and installed on the short-circuit connector, and the stability and positioning accuracy are poor

When the short-circuit terminal is plugged into the port of the external short-circuit box, when the short-circuit terminal and the short-circuit box collide or are affected by external forces, it is easy to rotate and move along its axial direction, and the positioning accuracy is poor, resulting in multiple short circuits. The length of the terminals protruding from the shorting connector is inconsistent, so that some of the shorting terminals and the shorting box have a virtual connection

At the same time, after the shorting terminal installed with the limited structure rotates, it does not match the port of the terminal box, which makes installation difficult and requires adjustment, which is time-consuming and laborious

[0004] Secondly, traditional shorting connectors generally do not have a waterproof and sealed structure, and cannot be used in environments requiring high protection levels, which limits their scope of application and reduces the safety performance of shorting connectors
