Bayonet type lamp holder body

Abstract

The invention discloses a bayonet type lamp holder body which comprises a lamp holder shell, a driving board and an electric connecting piece, wherein the driving board is accommodated in the lamp holder shell; the electric connecting piece comprises two electrode contact pins and a connecting seat; the two contact pins are fixed on the connecting seat; one or more positioning columns are arranged on the connecting seat; the driving board is provided with positioning holes corresponding to the positioning columns; during assembling, the positioning columns are inserted into the positioning holes to fix the connecting seat on the driving board; one end of each of the electrode contact pins is welded on the driving board, and the other ends of the two electrode contact pins extend out of the lamp holder shell, and are electrically connected with a socket outside the bayonet type lamp holder body. According to the bayonet type lamp holder body, the electrode contact pins can be kept fixing relative to the driving board during welding because the connecting seat is fixed on the driving board through the positioning columns in advance, and then the driving board can be transmitted to a welding station for automatic welding; the electrode contact pins are not required to be manually welded, so that the bayonet type lamp holder body has the advantage of simplicity in assembly.

Description

technical field [0001] The invention relates to a lamp head body, in particular to a socket type lamp head body. Background technique [0002] At present, the commonly used lamp body structures on the market are mainly screw lamp body and socket lamp body. There are two main types of traditional socket lamp body, one is to use the electrode pin riveted on the bottom of the lamp body to realize the fixed connection of the electrode pin and the lamp shell, and then use the wire to electrically connect the conductive pin to the drive board ; The other is to solder the two electrode pins directly to the driver board respectively. [0003] For example, a Chinese patent with a publication date of February 22, 2013 and a patent application number of 201320081232.5 discloses an LED lamp. The high-power LED lamp is composed of a heat sink, an LED light source, an end cover, pins, an LED lens and an LED drive circuit. The LED light source is installed at one end of the heat sink, an...

Problems solved by technology

[0004] However, due to the technical difficulty of directly welding the two electrode pins to the drive board, and the high rate of welding failures; the electrode pins are riveted to the bottom of the lamp body, and then the conductive pins are electrically connected to the drive board with wires The method of assembly is complicated, the production efficiency is low, and the wires connecting the electrode pins and the driver board are prone to poor contact
