Description

A kind of lamp switch

Technical field

The utility model relates to a kind of light switch class, and more particularly, it relates to a kind of device that connects the lamp switch that uses on movable electric wire.

Background technology

At present, the lamp switch of selling on market and using can only could use in less power bracket safely, otherwise damages easily, also can cause short circuit when serious and shortcoming such as cause catching fire.Up to the present, not seeing as yet on market can be for lamp switch safe in utilization in the more high-power scope.

Summary of the invention

The purpose of this utility model is to have overcome deficiency of the prior art, provide a kind of simple in structure, can be for lamp switch safe in utilization in the more high-power scope.

The purpose of this utility model is to be achieved by following technical proposals.

Lamp switch of the present utility model, comprise upper shell and lower house, be provided with rectangular port in the described upper shell, in port, be provided with push button and support plate, be provided with the cavity that has groove in the described push button, in cavity, be placed with conducting strip and spring, be provided with two conductive base pins in the described support plate, in order to contact energized by conducting strip.

Described conductive base pin is that flat-shaped metal forming is made; It is rectangular-shaped that described conductive base pin is that metal is made; It is cylindric that described conductive base pin is that metal is made; Described upper and lower casing preferably respectively is that half ellipticity constitutes.

Lamp switch of the present utility model has following beneficial effect compared with prior art:

1. the use power bracket is big, the life-span is long.

Description of drawings

Fig. 1 is a cutaway view of the present utility model;

Fig. 2 is the upward view of upper shell of the present utility model;

Fig. 3 is the stereogram of push button of the present utility model and conducting strip.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing:

In the drawings, upper shell 1 and lower house 2 respectively are that half ellipticity constitutes, a groove 3 is set on the aspect under one end of upper shell 1 makes lead-out wire usefulness, a rectangular port 4 is set and at less about 2mm wall thickness of reserving simultaneously suitable for reading at interlude, under two ends aspect on median line, leave screw hole 5 usefulness that fixes near port 4.The two ends of lower house 2 are positioned at that the lead wire outlet of a hole and an end is left in screw hole 5 corresponding positions and all the other are ghost.The centre, top that is contained in the push button 6 in the port 4 is protruding side's shape, the bottom is a rectangle, leave the cavity spring 7 of packing in the top, leave the cavity of rectangular recess shape in the bottom, vertically leaving the groove conducting strip 8 of packing into towards the chamber wall in cavity mouth intermediate lateral can up and downly be advisable, and conducting strip 8 is made the plush copper that symmetry is reserved in both sides in the middle of the rectangle for sheet metal.Can or be screwed with glue with support plate 9 below in port 4, support plate 9 is for being provided with the step of plush copper shape in the middle of rectangle one end, above one end of conducting strip 8 is parked on when being used to close power supply, two conductive base pins of making by sheet metal 10 of interlude embedding separated by a distance on the line of symmetry of support plate 9, expose top using for flat strip shaped contacts as conducting strip 8, exposing following is to have screwed hole in the square block of being a bit larger tham screw cap of 90 degree moulding and the screw of packing into is used to connect electric wire, and conductive base pin 10 also available metal is made rectangular-shaped, embedding such as cylindric or be encased on the support plate 9.

Described push button and the most handy thermosetting plastic of support plate are made.Upper and lower casing available heat thermoplastic plastic is made.

The utility model is made and can be used with interior power at 800W with general thermosetting plastic, can make and can use in bigger power bracket with the high thermosetting plastic of heatproof as required.
