Abstract
The utility model relates to a kind of non-arc contactor major loop syndeton, for solving non-arc contactor mechanical contact and silicon controlled connectivity problem, structurally remain the structures such as the terminal block of existing direct-acting contactor, fixed contact, contact support, contact bridge.Every bar break-make circuit has left and right two terminal blocks, and symmetrical layout is fixed on pedestal, is respectively used to connect input, output line.Terminal block is equipped with fixed contact, or one.On left and right two terminal blocks connecting input, output line, a cushion block is respectively housed, be connected to controllable silicon between two cushion blocks, cushion block and controllable silicon form a portal structures, and controllable silicon and left and right two terminal blocks are connected in parallel simultaneously.This utility model is simple and compact for structure, stable connection, changes contact convenient, does not affect the on-off action of contact bridge, also do not affect the temperature rise in whole loop during work.
Description
Technical field
The utility model belongs to low voltage component, specifically a kind of non-arc contactor major loop syndeton.
Background technology
Contactor is mainly used in AC and DC circuit, and connecting and point deenergizing for remote, is the product had a large capacity and a wide range.Some needs to connect continually and point deenergizing, electric arc will be produced when point deenergizing, electric arc can make the continuous scaling loss in dynamic and static contact, the useful life of product is very restricted, as arc extinguishing is taken effective measures, circuit will be made to be difficult to disjunction, contact melting welding occurs and parts are burnt out, and all will release energy in each breaking course, waste electric energy.Therefore, non-arc contactor is the product dreamed of, be engaged in the scientific research personnel of this industry and Engineering Technician always in constantly exploring, because the difficult point of capturing is a lot, up to the present, also do not have a product to obtain stable application in practice both at home and abroad, in the structure of mechanical contact and controllable silicon parallel connection, it is exactly a difficult point that fixed contact line part is connected with silicon controlled.The structure that the utility model provides can be good at solving this difficult point.
Summary of the invention
The utility model, for solving non-arc contactor mechanical contact and silicon controlled connectivity problem, provides a kind of major loop syndeton simple and compact for structure, easy to maintenance.
Technical scheme
The utility model remains the major loop syndeton of direct-acting contactor, comprise terminal block 8, fixed contact 9, contact support 4, contact bridge 2, every bar break-make circuit has left and right two terminal blocks 8, and symmetrical layout is fixed on pedestal 10, is respectively used to connect input, output line.Fixed contact 9 is screwed on terminal block 8.During work, contact support 4 drives contact bridge 2 to move downward or upward, makes the moving contact 5 at contact bridge 2 two ends contact with the fixed contact 11 on fixed contact 9 or separate, realizes being switched on or switched off of circuit.For solving non-arc contactor mechanical contact and silicon controlled connectivity problem, the utility model is respectively equipped with a cushion block 6 on left and right two terminal blocks 8 connecting input, output line, controllable silicon 1 is connected between two cushion blocks 6, cushion block 6 and controllable silicon 1 form a portal structures, and controllable silicon 1 and left and right two terminal blocks 8 are connected in parallel.
In technique scheme, terminal block 8 and fixed contact 9 also can be one.Cushion block 6 is L shape blockss, can be also U-shaped body, cuboid or cylinder, is screwed on fixed contact 9, terminal block 8 and pedestal 10.
Beneficial effect
The utility model remains the major loop syndeton of direct-acting contactor, and solves non-arc contactor silicon controlled connectivity problem by the portal structures that cushion block 6 and controllable silicon are formed, simple and compact for structure, stable connection; Contact bridge is positioned at portal structures, and during work, contactor carries out on-off action, and portal structures is motionless, and the two does not interfere with each other, and both ensure that and has changed the convenience of contact, in turn ensure that the temperature rise in the connection of fixed contact and whole loop is unaffected.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is the utility model structural front view.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model remains the major loop syndeton of direct-acting contactor, comprise terminal block 8, fixed contact 9, contact support 4, contact bridge 2, every bar break-make circuit has left and right two terminal blocks 8, symmetrical layout is fixed on pedestal 10, is respectively used to connect input, output line.Fixed contact 9 is screwed on terminal block 8.During work, contact support 4 drives contact bridge 2 to move downward or upward, makes the moving contact 5 at contact bridge 2 two ends contact with the fixed contact 11 on fixed contact 9 or separate, realizes being switched on or switched off of circuit.For solving non-arc contactor mechanical contact and silicon controlled connectivity problem, the utility model is respectively equipped with a cushion block 6 on left and right two terminal blocks 8 connecting input, output line, controllable silicon 1 is connected between two cushion blocks 6, cushion block 6 and controllable silicon 1 form a portal structures, and controllable silicon 1 and left and right two terminal blocks 8 are connected in parallel.
In the above-described embodiment, terminal block 8 and fixed contact 9 also can be one.Cushion block 6 is L shape blockss, can be also U-shaped body, cuboid or cylinder, is screwed on fixed contact 9, terminal block 8 and pedestal 10.
