Abstract
The utility model provides a wiring board mechanism for an alternating-current contactor, mainly for solving the problem that the conventional wiring board for the alternating-current contactor is easy to get loose, or complex in operation. The wiring board mechanism is characterized in that, a clamping groove which is symmetrical in left-right direction is arranged at a central part of a wiring board, a base is internally provided with a U-shaped arc ignition piece having a straight slot on the bottom, clamping plates adapted to the clamping groove are arranged on two sides of the straight slot, and the wiring board is in snap connection with the U-shaped arc ignition piece. The wiring board mechanism provided by the utility model is advantageous in that, the wiring board is fixed with the U-shaped arc ignition piece by snap connection, so that the wiring board is securely fastened and is not easy to get loose after assembly, and the operation is simple.
Description
Technical field
The utility model relates to a kind of mechanism of A.C. contactor, is specifically related to a kind of terminal block mechanism of A.C. contactor.
Background technology
A.C. contactor is to be widely used as cut-offfing and control circuit of electric power.It utilizes main contacts to open and close circuit, carries out control command with auxiliary contact.A.C. contactor mainly contains four parts and forms: 1) electromagnetic system comprises sucking coil, moving iron core and static iron core; (2) contact system comprises that three groups of main contacts and one to two group are often opened, normally closed auxiliary contact, the interlock mutually that connects together of it and moving iron core; (3) arc-control device, the general bigger A.C. contactor of capacity all is provided with arc-control device, so that rapid breaking arc avoids burning out main contact; (4) insulation crust and annex, various springs, transmission mechanism, short-circuited conducting sleeve, binding post etc.When coil electricity, static iron core produces electromagnetic attraction, will move the iron core adhesive, because contact system links with moving iron core, therefore moving iron core drives three movable contact springs and moves simultaneously, the closing of contact, thus connect power supply.When coil blackout, suction disappears, and moving iron core interlock part relies on the reaction force of spring and separates, and main contact is disconnected, and cuts off the electricity supply.A.C. contactor is connected with external circuit by terminal block mechanism, and the assembling of the pressured boss processed of terminal block and the body reaches to combine closely and fixes, but this kind scheme often in use for some time, can be owing to the wearing and tearing of terminal block boss become flexible, perhaps use screw link plate, but complicated operation, operation is many and increase cost.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of terminal block mechanism of A.C. contactor, has solved mainly that the terminal block of existing A.C. contactor is easy to wear to be become flexible, or the problem of complicated operation.
The technical scheme that the utility model adopts: a kind of terminal block mechanism of A.C. contactor, comprise pedestal, terminal block, be provided with the electric arc hole in the described pedestal, described terminal block is installed in the pedestal, described terminal block one end is provided with fixed contact, the other end is provided with binding post, described fixed contact passes the electric arc hole, described terminal block middle part is provided with symmetrical draw-in groove, be provided with U-shaped striking part in the described pedestal, described U-shaped striking part bottom has a groove, and described groove both sides are provided with the clamp adaptive with draw-in groove, described terminal block and the clamping of U-shaped striking part, described terminal block centre position is provided with two compacting boss, and there is the slot that matches with the compacting boss below, described electric arc hole, and described compacting boss and slot are combined closely.
Position, upper end, described electric arc hole is louvre, shape triangular in shape.
The beneficial effects of the utility model are: adopt such scheme, terminal block is by fixing with the mode of U-shaped striking part clamping, make the terminal block assembling after more fastening being difficult for become flexible, and simple to operate.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Shown in Figure 3 in conjunction with Fig. 2 as Fig. 1, a kind of terminal block mechanism of A.C. contactor, comprise pedestal 1, terminal block 2, be provided with electric arc hole 5 in the described pedestal 1, described terminal block 2 is installed in the pedestal 1, and described terminal block 2 one ends are provided with fixed contact 6, and the other end is provided with binding post 9, described fixed contact 6 passes electric arc hole 5, described terminal block 2 middle parts are provided with symmetrical draw-in groove 7, are provided with U-shaped striking part 4 in the described pedestal 1, and described U-shaped striking part 4 bottoms have a groove 11, described groove 11 both sides are provided with the clamp 10 adaptive with draw-in groove 7, described terminal block 2 and U-shaped striking part 4 clampings, terminal block 2 connects and fixes with U-shaped striking part 4, and this kind fixed form is compared with traditional boss fixed form, more fastening being difficult for becomes flexible, compare with the screw fixed form, simple to operate, efficiency of assembling is higher.
Described terminal block 2 centre positions are provided with two compacting boss 8, and there is the slot 3 that matches with compacting boss 85 belows, described electric arc hole, and described compacting boss 8 is combined closely with slot 3, make terminal block 2 obtain U-shaped striking part 4 and the double fixed of suppressing boss 8.
As shown in Figure 4, position, 5 upper end, described electric arc hole is louvre, shape triangular in shape.The electric arc hole of this kind shape can be imitated the track routes of electric arc and the zone that heat-dissipating space covers effectively, heat is distributed timely, and the heat of inside is difficult for the too high product failure that causes of accumulation when having guaranteed the product action, improves product useful life.
