Description
Technical field:
The utility model relates to electrical equipment, specifically a kind of explosion-proof electrical source 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 another 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, explosion-proof electrical source switch that safety is good are provided.
The utility model can reach by following measure:
A kind of explosion-proof electrical source switch, be provided with panel, back side of panel is provided with terminal box, and terminal box is provided with binding post, the front that it is characterized in that panel is provided with movably magnetic patch, be provided with division board in the terminal box, the one side of division board is provided with iron block, and another side is provided with two conductive contacts, conductive contact is connected with binding post through lead respectively, division board is provided with through hole, and connecting rod passes through hole one end and is connected with magnetic piece, and the other end is connected with conducting strip.
The utility model is inhaled mutually with magnetic piece under the effect of iron block, two conductive contacts are in released state, be that switch is in closed condition, when the movably magnetic patch on the panel is in magnetic piece at once on panel, movably the magnetic patch suction that attracts magnetic piece to overcome fixed and iron block moves to panel, contact with two conductive contacts by the connecting rod conducting strip, 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.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
A kind of explosion-proof electrical source switch, be provided with panel 1, the front of panel 1 is provided with movably magnetic patch 2, panel 1 back side is provided with terminal box 3, terminal box 3 is provided with binding post 4, be provided with division board 5 in the terminal box 3, the one side of division board 5 is provided with iron block 6, another side is provided with two conductive contacts 7, conductive contact 7 is connected with binding post 4 through lead respectively, division board 5 is provided with through hole, connecting rod 8 passes through hole one end and is connected with magnetic piece 9, the other end is connected with conducting strip 10, the utility model is inhaled mutually with magnetic piece under the effect of iron block, two conductive contacts are in released state, be that switch is in closed condition, when the movably magnetic patch on the panel is in magnetic piece at once on panel, movably the magnetic patch suction that attracts magnetic piece to overcome fixed and iron block moves to panel, contact with two conductive contacts by the connecting rod conducting strip, be that switch is in open mode, because panel is a closure panel, conducting strip and conductive contact contact area are big, 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.
