Microneedle type wire connecting device

Abstract

The invention discloses a microneedle type wire connecting device, which comprises an upper shell, a lower shell, a plurality of conductive alloy microneedles and an electric conductor, wherein the upper shell and the lower shell are connected through a fastener; a plurality of wire grooves are formed in the lower shell, to-be-connected wires are placed in the wire grooves, and the lower surface of the upper shell can tightly press the wires; the electric conductor is arranged in the lower shell; the conductive alloy microneedles are vertically arranged, the lower ends of the conductive alloymicroneedles are fixedly connected with the electric conductor, the upper ends of the conductive alloy microneedles extend into the wire grooves, and the conductive alloy microneedles are inserted into the bare conductors of the wires after piercing the insulating layers of the wires. The beneficial effects of the invention are that: the conductive alloy microneedles are made of a high-strength alloy material, are inserted into the bare conductors after penetrating into the insulating layers of the wires, and are in good contact with the bare conductors, thereby guaranteeing the electrical contact area of the conductive alloy microneedles with the main wire and the auxiliary wire, and improving the electrical conduction capability between the main wire and the auxiliary wire.

Description

technical field [0001] The invention relates to wire connection technology, in particular to a microneedle wire connection device. Background technique [0002] In power engineering, especially power line engineering, the connection of two insulated wires or bare wires is very common. When two wires are connected, under the condition of ensuring the electrical safety of the operator, the mechanical tensile strength, electrical conduction capacity and electrical insulation strength between the two wires should meet the requirements. For the convenience of description, the wire to be incorporated is called the main wire, and the wire to be incorporated is called the tutor wire. At present, there are the following three methods for connecting the main and auxiliary wires on site. [0003] The first connection method is: the main wire is the wire that is energized and running, and the auxiliary wire is the wire to be connected to the energized line (the wire that is about to b...

AI Technical Summary

Problems solved by technology

This connection method has the following problems: it is extremely unsafe to operate with electricity at high altitude, it requires a high technical level of the operator, the mechanical tensile strength cannot meet the requirements, and in the "binding method" of the main and auxiliary wires, the electrical The conduction ability is also difficult to meet the requirements, so there are often poor contacts between the main wire and the auxiliary wire, and even oxidation and burning faults at the connection

This connection method is simple, but there are also the following problems: the mechanical tensile strength, conductivity or connection impedance between the main and auxiliary wires are difficult to meet the specified requirements, and the main and auxiliary wires must be bare wires
