CN2049021U - Safe spring inserting type lamp base and lamp holder - Google Patents

Abstract

The utility model discloses safe spring inserting type lamp base and lamp holder, which are a round lamp holder with a spring sheet and a direct-inserting type lamp base which is matched with the lamp holder; the lamp holder is made of metallic material. With the safe spring inserting type lamp base and lamp holder being used, the work of installing an electric bulb by rotating can be avoided. The utility model provides the convenient and safe lamp base and lamp holder.

Description

Safe spring inserting type lamp base and lamp holder

The utility model relates to lamp holder and the socket on a kind of bulb, promptly safe elastic force Socket lamp holder and socket, and it belongs to field of illuminating lamps.

Present illuminating lamp, specification is a lot, have wide range of applications, but mostly the lamp holder of they and lamp socket connection place and socket is spiral and two kinds of bayonet types, complex structure, loading and unloading inconvenience, the safety assurance degree is low.Especially to steep above-mentioned shortcoming more obvious for the high-altitude illuminator lamp.

Shortcoming in view of above-mentioned existence, the purpose of this utility model is to design a kind of safe elastic force Socket lamp holder and socket, civilian incandescent lamp and fluorescent tube all are suitable for, its simple structure, safe and reliable, it is convenient to change, and can be used as corridor, stair, the high-altitude illumination and the household illuminating lamp of public place.

The utility model is to realize like this, basic general lighting usefulness screw socket, bayonet-type bulb and the socket with original technology of the shape of this socket and overall dimension is identical, and it is characterised in that the direct insertion socket that the circle band shell fragment that an elastomeric material is pressed into is arranged at the bottom of insulating joint card.The inwall of the insulator of staying is close in the outside of shell fragment, and when lamp holder inserted, the lamp shell extrusion elastic made its distortion, and is stuck in the socket place securely.Axle at the lower insulator of socket shell helps under the effect, produces enough power and finishes and connect task with shell fragment is common.The shell fragment of this socket is made up of the 4-10 sheet, can be swept away by brass material or Thin Elastic steel disc to form.All there is internal thread the upper insulator of this socket, lower insulator inside.Screw thread by insulating joint is connected, and also has two square holes or oblong aperture in the insulating joint, and elastic electrode joins by square hole and screw A, is used for connecting the positive electricity power supply.This lamp holder be shaped as taper, tapering is 5 °-10 °.

Be example with the incandescent lamp below, the utility model is described in detail.

Accompanying drawing 1 is the cutaway view of safety elastic force plug-in type socket and lamp holder.

Among the figure 1. tungsten filament, 2. lead, 3. foam, 4. insulate scolder, 5. be close to the insulator inwall 6. of staying with the outer wall of shell fragment socket.7. lamp shell is 5 °-10 ° bullet.When bulb inserted, 5. 7. lamp shell pushed the shell fragment with the shell fragment socket.At the socket shell, finish the connection task under the lower insulator booster action 6..8. elastic electrode passes insulating joint , two be separately fixed at little spiral shell 9. with  on, be used for by the positive electricity electric current.10. be the little plain washer that line ball is used with .

Accompanying drawing 2 is schematic diagrames of band shell fragment socket.5. shell fragment is stuck in the step place of insulating joint  lower end.

The formation of galvanic circle is that the live wire and the zero line (positive pole of DC power supply and negative pole) of power supply inserts respectively on two Screws of C.D, and live wire by elastic electrode 8., live wire enters tungsten filament and 1. provides in the A point contact, bulb.In the bulb zero line by B point through lamp shell 7., 5. the shell fragment card get back to zero line D point, the formation loop.Good in order to guarantee the contact of bulb live wire A point, 8. elastic electrode is designed to certain elasticity, made it regulating action preferably.

The elastic force connected structure of the utility model mechanical type. Have feature esy to use, safe and reliable, can be used for the high-altitude illumination of the public places such as corridor, stair, street lamp. Also can be used for the civilian general lightings such as family. As: can save ladder with high-altitude loading bar (applying for a patent simultaneously). Convenient, laborsaving, raise the efficiency.

Claims (4)

1. One kind by tungsten filament 1., lead 2., foam 3., the insulation scolder 4., safe elastic force Socket lamp holder and socket that 6. upper insulator , lower insulator form is characterized in that:

   A: the direct insertion socket that there is a garden shape band shell fragment at socket and the lamp holder place of plugging 5.;

   B: upper insulator , lower insulator 6. inwall all have screw thread;

   C: there is screw thread insulating joint  outside, in two square holes are arranged;

   D: lamp holder is the taper lamp holder.
2. 2. safe elastic force Socket lamp holder as claimed in claim 1 and socket is characterized in that the shell fragment at socket place is made up of the 4-10 sheet.
3. 3. safe elastic force Socket lamp holder as claimed in claim 2 and socket is characterized in that the shell fragment at socket place is made by brass material or Thin Elastic steel disc.
4. 4. safe elastic force Socket lamp holder as claimed in claim 1 and socket, the tapering that it is characterized in that lamp holder are 5 °-10 °.
