Phenolic lampholder

Abstract

The invention relates to a phenolic lampholder. The phenolic lampholder comprises a metal sheath shell, an insulator, an electric conduction cap and an electric conduction wire, a through hole is formed in the top of the metal sheath shell, the insulator is made of phenolic composition in an integrated compression mode and provided with a wire inlet hole penetrating through the insulator, the insulator is fixedly arranged in the through hole in the metal sheath shell, the electric conduction cap is installed at the top of the insulator, and the electric conduction wire is connected to the electric conduction cap and stretches into the metal sheath shell along the wire inlet hole in the insulator. The phenolic composition replaces plastic and glass to serve as the insulator, and the high-temperature-resistant and environment-friendly performance of the phenolic composition is fully used, so that the use safety is improved, and the phenolic lampholder can be widely applied to the field of high-power lighting lamps.

Description

technical field [0001] The invention relates to the technology in the field of lamp holders, in particular to a bakelite lamp holder made of bakelite as an insulator. Background technique [0002] 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 need for environmental protection; at the same time, glass insulators are also prone to cracks or breakage, result...

Problems solved by technology

[0002] 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 need 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; Poor high-temperature performance makes it impossible to be used in some high-power lighting lamps. Therefore, it is difficult for plastics to replace glass materials in the field of high-power lighting lamps. Therefore, how to overcome the problems of high temperature resistance and environmental protection is a topic that needs to be improved urgently in the industry.
