Abstract

The utility model relates to a separate assembled lamp holder, which is composed of a separate holder casing, an earth wire assembly, a live wire assembly and a connection screw, wherein the earth wire assembly and the live wire assembly are arranged in the separate holder casing, an earth wire contact piece is arranged at the bottom of a screw hole, a lamp waist contact piece of a live wire contact piece is arranged on one side wall of the screw hole and the live wire contact piece and the earth wire contact piece are made of elastic metal. Because the lamp holder is designed into a separate type, a metal lamp cap seat ring is replaced by the live wire contact piece, and the earth wire contact piece and the live wire contact piece are separately arranged, the utility model thoroughly eliminates the wire connection short circuit problem of the live wire and the earth wire and also eliminates the mechanical fixed connection structure between a leading wire and the contact piece. The hook-shaped lamp waist contact piece arranged at the upper end of the live wire contact piece can ensure reliable contact between a live wire and an earth wire after a screw lamp bulb is screwed in and can also ensure the stability of the lamp bulb in the lamp holder. The metal dosage of the separate lamp holder is 20 percents of the existing products. The utility model has the advantages of good fabrication technology of each part, easy mass production and convenient installation.

Description

Separate assembling lamp adapter

Technical field:

The utility model relates to a kind of lamp socket, relates in particular to a kind of lamp screw base seat.

Background technology:

At present, the lamp screw base seat of the common use of people, as shown in Figure 1, by bakelite lamp holder shell 5, spiral metal lamp head ring 6 and end contact 7 and two wiring are formed, spiral metal lamp head ring 6 is arranged in the lamp holder shell 5, the bottom of the bottom of spiral metal lamp head ring 6 and bakelite lamp holder shell 5 is riveted into one by metal rivet 8, contact of the same end 7 also is riveted on the bottom of bakelite lamp holder shell 5, a wiring is welded on the spiral metal lamp head ring 6, another root bead is connected on the end contact 7, this lamp socket is an integral type, spiral metal lamp head ring 6 also is an integral type, have breach in its bottom, be convenient to install end contact 7, in

case end contact

7 and 6 short circuits of spiral metal lamp head ring, this integral type lamp socket, the difficulty of processing of spiral metal lamp head ring 6 is bigger, spiral metal lamp head ring 6 used amounts of metal are big, economy is bad, simultaneously when the specification of bulb socket hour, because spiral metal lamp head ring 6 and end contact 7 all are riveted on the bottom of bakelite lamp holder shell 5, both are difficult to be in staggered distribution, and the bending that the left end of end contact 7 can only be made progress makes it to stagger, in case short circuit, but in actual use, after the elasticity of end contact 7 is moved back mistake, be easy to cause end contact 7 to contact and produce short circuit with spiral metal lamp head ring 6, thereby this integral type lamp socket was both uneconomical, and was also unreliable.

Summary of the invention:

Goal of the invention of the present utility model is: a kind of separate assembling lamp adapter is provided, and it can effectively overcome the deficiency that existing product exists, and metal consumption is few, and the processing technology of each part is good, and is safe and reliable.

The utility model is realized the foregoing invention purpose by following technical solution.

Separate assembling lamp adapter described in the utility model, form by split seat shell, ground wire sub-assembly, live wire sub-assembly and attachment screw, split seat shell is combined by upper shell and lower house, be provided with the positioning spigot structure between upper shell and the lower house, ground wire sub-assembly, live wire sub-assembly are arranged in the split seat shell, are integral by the attachment screw fixed combination between upper shell and the lower house; The ground wire sub-assembly is made up of ground wire lead-in wire, ground wire contact, and the ground wire lead-in wire is fixedlyed connected with the ground wire contact, and the ground wire contact is arranged on the place, screwed hole bottom of split seat shell, and the outer end of the lamp tail contact chip on the ground wire contact skips over the center of screwed hole; The live wire sub-assembly is made up of live wire lead-in wire and live wire contact, and live wire goes between and fixedlys connected with the live wire contact, is provided with lamp waist contact chip in the upper end of live wire contact, and lamp waist contact chip is arranged on the sidewall of screwed hole of split seat shell; The material of live wire contact and ground wire contact is the elastic metallic that conducts electricity very well.

On lower house, be provided with screwed hole, screwed hole bottom, live wire contact locating piece, live wire contact installation hole, live wire contact location notch, ground wire contact location notch, positioning strip, connecting hole, live wire outlet, ground wire outlet; Live wire contact installation hole is arranged on the thread segment of screwed hole, live wire contact location notch is arranged between screwed hole bottom and the live wire outlet, ground wire contact location notch is arranged between screwed hole bottom and the ground wire outlet, and the structure of upper shell is corresponding with lower house, locatees by positioning strip between the two.
