Embodiment Construction

[0013] Such as figure 2 As shown, it is an embodiment of a lamp head of the present invention, which includes a housing 1, and the pin 4 on the housing is a cylindrical cavity protruding outward, with a diameter of 2 mm and a protrusion height of 2.3 mm, which is integral with the housing itself Stamping structure. The shell is a cylindrical cavity with one end open, wherein the diameter of the open end of the shell is larger than that of the sealed end. The sealing end of the shell is composed of an electric contact piece 3 and a black glass insulating part 2, and the shell, the electric contact piece and the black glass insulating part are poured into one body. The thickness of the black glass insulating part is 3mm higher than that of the pin, and the side wall of the black glass insulating part is poured into the cylindrical cavity of the pin to increase the mechanical strength. There are two electrical contact pieces, which are distributed symmetrically with the center...

Abstract

The invention discloses a lamp cap and a manufacturing method thereof. The lamp cap comprises a shell body and a pin connected with the shell body as a whole structure; the pin is a cylindrical cavity with the diameter being 2mm and the protruding height being 2.3mm; black glass is filled in the cylindrical cavity; the shell body and the pin are made of copper, aluminum or steel. The manufacturing method comprises the steps of using a pressing machine to press the material into the shell body; extruding the shell body through an extruder to form a pin structure; placing an electric contact piece; and pouring the black glass to enable the black glass to be filled in the pin. The lamp cap can effectively avoid the loosening and falling-off of the pin, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a lamp holder and a manufacturing method thereof. Background technique [0002] Existing lamp holder structures such as figure 1 As shown, it includes a shell 1, a pin 4, an electrical contact piece 3, and a black glass insulating part 2. The manufacturing method is as follows: 1) stamping out a cylindrical shell; 3) Fix two metal wires in the two holes through special equipment; 4) Place the electrical contacts and pour black glass. Because the two pins of the existing lamp holder are assembled on the lamp housing and fixed by black glass casting, and the thickness of the housing is generally about 0.2mm, it is easy to cause the pins and the housing to loosen during use, and even the pins fall off. This has just formed very big potential safety hazard. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a lamp hol...
