Novel terminal strip with visual wiring state

Abstract

The invention relates to the technical field of power equipment, and particularly discloses a novel terminal strip capable of visualizing a wiring state. The novel terminal strip comprises a plastic part, wherein the interior of the plastic part is provided with an accommodating cavity, the top of the plastic part is provided with a glue passing port communicating with the accommodating cavity, and the side surface of the plastic part is provided with a wire inserting hole communicating with the accommodating cavity and used for insertion of a wire; a metal frame which is arranged in the accommodating cavity, wherein a penetrating groove is formed in the middle of the metal frame; a metal short-circuit sheet which is fixedly connected with the plastic part, wherein the end part of the metal short-circuit sheet penetrates through the through groove and is slidably connected with the metal frame along the through groove; a tightening bolt which sequentially penetrates through the plasticpart and the top of the metal frame and is in threaded connection with the metal frame to drive the metal frame to slide up and down along the cavity wall of the accommodating cavity; an insulating block which is positioned in the accommodating cavity and is positioned under the glue passing port; and an insulating connecting rod, wherein two ends of the insulating connecting rod are fixedly connected with the insulating block and the metal frame respectively. According to the invention, the wiring quality of operation and maintenance personnel can be improved and the situation that a tightening bolt is too loose or too tight can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a novel terminal block with visualized wiring state. Background technique [0002] The terminal block is a conductive part used to realize mutual conduction between wires. The function of the terminal block is to connect the lines of the two electronic devices to transmit signals (current and voltage). With the terminal block, the wiring is beautiful and the maintenance is convenient. The connection between the long-distance lines is mainly reliable, and the construction and maintenance are convenient. [0003] A conventional terminal block generally includes a plastic part provided with several wire insertion holes, conductive metal located in the insertion holes, and tightening bolts protruding into the wire insertion holes for cooperating with the conductive metal to clamp the wires. [0004] Traditional terminal blocks cannot tell whether the tightening bolts hav...

AI Technical Summary

Problems solved by technology

[0004] The traditional terminal block cannot visually know whether the tightening bolts have been tightened. It is basically based on the feel, which is easy to cause over-tightening or over-loosening.
