Abstract
The utility model relates to a switch for electrical appliances. Specifically the utility model is an explosion proof switch, which is provided with a faceplate. The rear face of the faceplate is provided with a terminal box. The terminal box is provided with a binding post. The utility model is characterized in that the front face of the faceplate is provided with a movable magnetic block and the rear face of the faceplate is provided with two conducting contacts. The conducting contacts are connected to the binding post respectively. The terminal box on the side of the conducting contacts is provided with a magnetic conducting strip. The conducting strip is provided with a positioning spring. The faceplate of the utility model is a closed faceplate. The contact area between the conducting strip and the conducting contact is relatively large. No fire or explosion may occur in the exposed part. The utility model has the advantages of simple structure, low cost, long service life, easy operation and high safety.
Description
Technical field:
The utility model relates to electrical equipment, specifically a kind of flame-proof switch.
Background technology:
We know, in the electrified epoch, all be a mass of various electrical equipment in each family, the bound naturally switch of electrical equipment is arranged, existing switch generally adopts lever, it is provided with panel, the back side of panel is provided with junction box body, terminal box is provided with two binding posts, a binding post connects power firestreak, another binding post circuit closer input live wire, binding post is connected with contact in the terminal box respectively, one of them contact is provided with balance pivot, lever is that an electric conducting material is made, knob is provided with retainer spring and driving lever, knob is installed on the terminal box, and driving lever is matched with lever, panel is provided with a knob hole, during use, when knob was in the closed position, a lever and an other contact were separated the electrical equipment no power, when knob is shown in an open position, lever contacts with an other contact, and two binding posts are connected, the electrical equipment energising, to reach the purpose of appliance switch, the panel of this switch must be provided with the knob hole, and the switching surface of terminal box can not seal, when conductive materials such as water enter, to produce the switch explosion phenomenon, the lever of this switch and the contact area of contact are little, occur loose contact when opening switch easily, even sparking may occur, explosion phenomenon, all with the safety of the serious threat person and electrical equipment, also there is complex structure in this switch to above-mentioned phenomenon, the cost height, fragile, deficiencies such as useful life is short.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, with low cost, long service life, flame-proof switch that safety is good are provided.
The utility model can reach by following measure:
A kind of flame-proof switch, be provided with panel, back side of panel is provided with terminal box, terminal box is provided with binding post, the front that it is characterized in that panel is provided with movably magnetic patch, and the back side of panel is provided with two conductive contacts, and conductive contact is connected with binding post respectively, be provided with magnetic conducting strip in the terminal box of conductive contact one side, conducting strip is provided with retainer spring.
Panel front in the utility model can adopt the chute mode to be connected with magnetic patch movably, and magnetic patch is gone up moving about bottom right by chute, to reach opening or closing of switch.
The utility model magnetic conducting strip and two conductive contacts under the effect of retainer spring are in released state, be that switch is in closed condition, movably magnetic patch on panel is in magnetic conducting strip at once, the resistance that magnetic patch attracts magnetic conducting strip to overcome retainer spring moves to panel, conducting strip contacts with conductive contact, be that switch is in open mode, the utility model is because panel is a closure panel, conducting strip and conductive contact contact area are big, sparking can not appear in exposed parts, explosion phenomenon has simple in structure, with low cost, long service life, easy to use, advantages such as safety is good.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model, also is the structural representation of a kind of embodiment.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of flame-proof switch, be provided with panel 1, panel 1 back side is provided with terminal box 2, panel 1 adopts closed the connection with terminal box 2, the front of panel 1 is provided with movably magnetic patch 5, panel 1, movably magnetic patch 5 can adopt chute to be connected, also can be provided with magnetic block on one side of panel, be connected by magnetic, the back side of panel 1 is provided with two conductive contacts 6,7, terminal box 2 is provided with two binding posts 3,4, conductive contact 6,7 respectively with binding post 3,4 are connected, conductive contact 6, be provided with magnetic conducting strip 8 in the terminal box 2 of 7 one sides, conducting strip 8 is provided with retainer spring 9, the other end of retainer spring 9 can be connected with panel 1, also can be connected with terminal box 2, under the effect of retainer spring 9, magnetic conducting strip 8 and two conductive contacts 6,7 are in released state, be that switch is in closed condition, when the movably magnetic patch 5 on the panel is on the panel 1, the resistance that magnetic patch 5 attracts magnetic conducting strip 8 to overcome retainer spring 9 moves to panel, conducting strip 8 and conductive contact 6,7 contact, be that switch is in open mode, the utility model is because panel is a closure panel, conducting strip and conductive contact contact area are big, and sparking can not appear in the part that exposes, the phenomenon of blast has simple in structure, with low cost, long service life, easy to use, advantages such as safety is good.
Claims (2)
1, a kind of flame-proof switch, be provided with panel, back side of panel is provided with terminal box, terminal box is provided with binding post, the front that it is characterized in that panel is provided with movably magnetic patch, and the back side of panel is provided with two conductive contacts, and conductive contact is connected with binding post respectively, be provided with magnetic conducting strip in the terminal box of conductive contact one side, conducting strip is provided with retainer spring.
2, a kind of flame-proof switch according to claim 1 is characterized in that said panel and magnetic patch movably adopt chute to be connected.
