Problems solved by technology

The lamp holder has the following disadvantages: 1. Since the metal threaded shell is a shell set, the metal material is much, the cost is high, and resources are wasted; 2. After the metal threaded shell and the plastic shell are assembled, they still need to be fixed by riveting process, and there are many processes. Low processing efficiency and high cost

Abstract

The invention discloses a lamp holder and a manufacturing method thereof. The lamp holder comprises an insulator, a spiral electric lead and a conducting cap, wherein the spiral electric lead is fixedly connected to the outside of the insulator and is matched with the insulator to form a conducting external thread which can be screwed with a spiral lamp carrier, and the conducting cap is fixedly connected on the insulator, and is insulated with the spiral electric lead. The manufacturing method of the lamp holder comprises the following steps of: firstly, manufacturing the spiral electric lead; secondly, loading the spiral electric lead into a mould; and thirdly, manufacturing the insulator by injection molding, wherein the injection molding can ensure that the spiral electric lead is fixedly connected with the insulator, and the spiral electric lead is matched with the insulator to form the conducting external thread which can be screwed with the spiral lamp carrier. By adopting metal thread lines to replace metal thread shells in the technical background, the invention has the advantages that the use level of metal is low, the appearance of the lamp holder is simple and attractive, and because the metal thread lines and insulating belts are directly fixed together in injection molding, only less working procedures are needed, and the working efficiency is high.

Description

technical field [0001] The invention relates to a lamp cap. Background technique [0002] The existing lamp holder comprises a plastic shell, a conductive cap and a metal threaded shell. The metal threaded shell is fixed outside the plastic shell, the conductive cap is mounted on the top of the plastic shell, and the conductive cap is insulated from the metal threaded shell. When the lamp cap is screwed on the spiral lamp holder, the metal threaded shell is electrically connected to the first pole of the spiral lamp holder, and the conductive cap is electrically connected to the second pole of the spiral lamp holder. This lamp holder has the following disadvantages: 1. Since the metal threaded shell is a shell set, the metal material is much, the cost is high, and resources are wasted; 2. After the metal threaded shell and the plastic shell are assembled, they still need to be fixed by riveting process, and there are many processes. The processing efficiency is low and the...
