Abstract

The utility model discloses a short circuit-proof lamp socket, comprising a lamp shade and a base seat. The inner of the lamp shade is a screw thread lamp opening, and a conductive post is movably arranged in the middle of the base seat. The upper end of the conductive post is connected with a spring, and the insulated wire of the lower end of the conductive post is connected with a wire connecting plate. Because the conductive post which is arranged in the middle of the base seat of the utility model can only move upwards and downwards, the contact between the conductive post and the short circuit-proof lamp socket can be avoided when a lamp bulb is screwed in or screwed out, and the short circuit can not occur, which is safe and durable. Because the side surface of the screw thread lamp opening is not opened, the strength of the short circuit-proof lamp socket is increase. An insulating spacer is arranged in the short circuit-proof lamp socket, which increases the insulating performance. The utility model has the advantages of simple structure and low cost.

Description

Anti-short circuit lamp socket

The utility model relates to a kind of lamp socket, relates to a kind of anti-short circuit lamp socket specifically.

Employed lamp socket in the daily life mostly adopts bow type contact electrode and side that the metal threaded socket of opening is arranged, and the bow type contact electrode of this socket is fixing insecure, is short-circuited easily after the contact electrode is loosening; And this class lamp socket phenomenon of getting an electric shock easily; Because screw thread socket lateral opening is so reduced the intensity of lamp socket itself.

The purpose of this utility model is to provide a kind of and can be short-circuited, good insulation preformance, and safety durable, simple in structure, the anti-short circuit lamp socket that cost is low.

The purpose of this utility model is achieved in that

Lamp socket comprises lampshade and base, is the screw thread socket in the said lampshade, and its structural feature is: said base intermediate active is installed conductive pole, connects spring on this conductive pole, and the insulated conductor of said conductive pole lower end connects terminal block.

In said screw thread socket bottom insulation spacer is installed.

Advantage of the present utility model is:

Because the conductive pole in the middle of the base can only move up and down, can not lateral displacement, so when screwing in or screw out bulb, avoid conductive pole to contact, so promptly can not be short-circuited safety durable with socket; Because of screw thread socket side opening not, so improved the intensity of lamp socket itself; In the socket bottom insulation spacer is installed, has been improved insulation property, increased the contact area of socket and base, prevent that socket is loosening, the intensity of raising itself; The utility model is simple in structure, and cost is low.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, lamp socket comprises lampshade 1 and base 9, in the said lampshade is screw thread socket 2, mounting groove 6 is arranged in the middle of the said base, the movable conductive pole 3 of installing connects spring 4 on the installing hole in the middle of the mounting groove on the conductive pole in mounting groove, and the insulated conductor 7 of conductive pole lower end connects terminal block 8, terminal block is fixed on the connection place of lampshade and lamp base, in said screw thread socket bottom insulation spacer 5 is installed.

Claims

1, a kind of anti-short circuit lamp socket, comprise lampshade (1) and base (9), in the said lampshade is screw thread socket (2), it is characterized in that: said base intermediate active is installed conductive pole (3), connect spring (4) on this conductive pole, the insulated conductor (7) of said conductive pole lower end connects terminal block (8).

2, anti-short circuit lamp socket according to claim 1 is characterized in that: in said screw thread socket bottom insulation spacer (5) is installed.
