Three-section electric connecting guide wire for electric light source and its manufacturing process

Abstract

The invention relates to a three-section electrical connection guide wire for an electric light source and a manufacturing process thereof. The electrical connection guide wire includes an inner guide wire, a sealing wire, and an outer guide wire. The inner guide wire is welded to one end of the sealing wire, and the sealing wire The other end is welded and connected with the outer guide wire, the inner guide wire and the outer guide wire are formed by twisting at least two conductive metal monofilaments along the central axis, the sealing wire is du magnesium wire, and the conductive metal wire of the inner guide wire is Copper-plated nickel wire, the conductive metal wire of the outer guide wire is copper wire, the inner guide wire of the three-section electrical connection guide wire, the sealing wire, and the outer guide wire are all concentric after welding, and can withstand a pressure of 40‑50N and bend at 90 degrees 3 back and forth without breaking, and the tension remains the same. Compared with the prior art, the welding point of the present invention is strong, and when it is sealed with glass, it is not easy to leak air, and it is not easy to generate air bubbles. When making the core column, there is less material jamming, the production efficiency is improved, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a three-section electric connecting guide wire for an electric light source and a manufacturing process thereof. Background technique [0002] The guide wire for electric light source is the only channel to introduce the electric energy outside the lamp tube into the lamp tube to make the lamp work. It is composed of three different materials, that is, the inner guide wire (the part inside the lamp tube), the outer wire (the part connecting the outside of the glass body with the lamp foot), and the sealing wire (the part sealed with the glass body). The guide wire is an important part of the lamp, and its requirements are: good electrical conductivity, good sealing after sealing with glass, and good stability when the lamp tube is working. Due to the problems of processing materials and manufacturing techniques, the existing guide wires are prone to weak welding points and poor...

AI Technical Summary

Problems solved by technology

Due to the problems of processing materials and manufacturing technology, the existing guide wire is prone to weak welding points and poor electrical conductivity. When the sealing wire and glass are sealed, it is easy to leak air and generate air bubbles. The straightness of the guide wire is not enough. Time and space are easy to jam materials, affecting production efficiency and increasing production costs
