Description

A plastic lamp

technical field

The utility model relates to the technology in the field of lamp caps, in particular to a plastic lamp cap in which an insulator is integrally formed with plastic.

Background technique

As we all know, the lamp cap is used as the connecting part between the bulb and the lamp holder; the traditional lamp cap is composed of a metal casing, a conductive cap, a conductive wire, and a glass insulator that insulates the conductive cap and the metal casing into one body. Poor dimensional consistency leads to large fit deviation, and glass insulator manufacturing requires high-temperature melting, so on the one hand, it needs to waste corresponding energy due to high-temperature heating of the glass, such as electric energy, and on the other hand, it will cause environmental pollution during the melting process, which obviously does not meet the advocacy. The demand for environmental protection; at the same time, glass insulators are also prone to cracks or breakage, resulting in a decrease in insulation performance and potential safety hazards; All insulators are made in combination, which will lead to low efficiency due to complex structure, troublesome installation and cumbersome processing, which is not conducive to production operations.
