Abstract

The utility model belongs to the field of low tension terminal appliance switches and specifically relates to a fuse-type disconnecting switch. A moving contact and fixed contact connecting member for the fuse-type disconnecting switch is disposed on the fuse-type disconnecting switch. The fuse-type disconnecting switch comprises an installing base plate, two insulated pillars fixed on the installing base plate, a moving contact and a fixed contact, wherein the moving contact and the fixed contact are arranged on the two insulated pillars respectively, the fixed contact is fixed on one insulated pillar and the moving contact is fixed on the other insulated pillar through a moving contact base; and the moving contact has a structure of double parallel blades. Two ends of the moving contact are connected to the fixed contact and the moving contact base respectively through clamping of U-shaped jump rings. When the disconnecting switch is in the on-state, the U-shaped jump rings enable surface contact to be formed between the moving contact and the fixed contact and between the moving contact and the moving contact base, so that the conduction rate of current is improved, contact resistance is reduced, the life span of the disconnecting switch is prolonged, the replacement rate of equipment is reduced, and reliability of power supply is improved.

Description

A kind of dynamic/static contact connector of fuse type disconnector
Technical field
The utility model belongs to low pressure terminal appliance field of switches, is specifically related to a kind of moving contact of fuse type disconnector and the connector of fixed contact.
Background technology
The advantage such as at present, low voltage fuse type isolating switch is cheap owing to having, stable, easy to maintenance and be applied to widely the outlet of bench type step down side.Existing low voltage fuse type isolating switch generally comprises mounting seat, is arranged on fixed contact and moving contact on mounting seat, and fuse link, is hinged with blade on described moving contact, the other end of blade when switch is closed and fixed contact join; Fixed contact and moving contact are arranged on insulated column respectively.In electric power system, low-pressure fusing disconnecting switch is being controlled the break-make of electric current, has important effect, and the connector between blade and fixed contact is one of important indicator of investigating low-pressure fusing isolation switch function admirable.Existing operating low-pressure fusing disconnecting switch is due to when switch is closed, usually because contact area very little (some contact or line contact), cause contact resistance very high, when working long hours, the face that easily comes in contact is overheated and burn out contact, have certain potential safety hazard, and it is short to have useful life, the problem that maintenance cost is high.
The utility model content
Technical problem to be solved in the utility model is, a kind of dynamic/static contact connector of fuse type disconnector is provided, by the architecture advances to this connector, make it become the face contact, prevent that contact-making surface is overheated and burn out contact, thereby eliminated potential safety hazard, reduced the turnover rate of equipment, improved power supply reliability.
In order to solve the problems of the technologies described above, the dynamic/static contact connector of a kind of fuse type disconnector of the present utility model, be located on fuse type disconnector, this fuse type disconnector comprises a mounting base, is fixed on two insulated columns on mounting base and is arranged at respectively two moving contact and fixed contacts on insulated column, described fixed contact is fixed therein on an insulated column, and described moving contact is fixed on another insulated column by movable contact block; Described moving contact adopts two parallel blade structures; Wherein, the two ends of described moving contact are connected on fixed contact and movable contact block by the clamping of U-shaped jump ring respectively.
Further, screw out the switching manipulation of disconnection and screw-in closure for the ease of two parallel blades of moving contact, U shape jump ring has wedge shape lead angle mouth.
Further, in order better to clamp the conductive contact surfaces of moving contact and fixed contact, the two side of described U-shaped jump ring all has the sandwich serface that concaves.
Further, that end that is connected with fixed contact of described moving contact also is provided with draw ring, carries out deciliter for insulation operation hook rod.Further, described draw ring is circular stainless steel draw ring.
Further, described insulated column is the epoxy resins insulation post, has hydrophobic, self-cleaning, uvioresistant, weatherproof and aging characteristic.
The utility model is by the structure of above-mentioned U shape jump ring, U shape jump ring has wedge shape lead angle mouth, and its U-shaped jump ring two walls all have the sandwich serface that concaves, not only can better clamp the conductive contact surfaces of moving contact and fixed contact and movable contact block, and mechanical deformation does not appear in the moving contact of guaranteeing clamping plate type, even certain distortion occurs, also can guarantee electric conductivity accurately entering under the guiding of the wedge shape lead angle mouth of U shape jump ring under closed position, effect at the sandwich serface of indent.When isolating switch was closed, the U-shaped jump ring made moving contact contact with fixed contact and movable contact block formation face, has improved the on-state rate of electric current, reduces contact resistance, has improved the useful life of isolating switch, has reduced the turnover rate of equipment, has improved power supply reliability.
Description of drawings
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the structural representation of U-shaped jump ring of the present utility model.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As a specific embodiment, as shown in Figure 1, the dynamic/static contact connector of a kind of fuse type disconnector of the present utility model, be located on fuse type disconnector, this fuse type disconnector comprises a mounting base 1, is fixed on two insulated columns 2 on mounting base 1 and is arranged at respectively two moving contact 3 and fixed contacts 4 on insulated column 2, described fixed contact 4 is fixed therein an insulated column 2, and described moving contact 3 is fixed on another insulated column by movable contact block.Insulated column 2 is selected the epoxy resins insulation post, has hydrophobic, self-cleaning, uvioresistant, weatherproof and aging characteristic.
Two parallel blades of described moving contact 3 are connected on fixed contact 4 and movable contact block by 9 clampings of U-shaped jump ring respectively.concrete, two parallel blades for the ease of moving contact 3 screw out the switching manipulation that disconnects and screw in closure, as shown in Figure 2, U shape jump ring 9 has wedge shape lead angle mouth 91, and the two side of its U-shaped jump ring 9 all has the sandwich serface 92 that concaves, not only can better clamp the conductive contact surfaces of moving contact 3 and fixed contact 4 and movable contact block, and mechanical deformation does not appear in the moving contact 3 of guaranteeing clamping plate type, even certain distortion occurs, also can accurately enter closed position under the guiding of the wedge shape lead angle mouth 91 of U shape jump ring 9, guarantee electric conductivity under the effect of the sandwich serface 92 of indent.When isolating switch was closed, U-shaped jump ring 9 made moving contact 3 contact with fixed contact 4 and movable contact block formation face, has improved the on-state rate of electric current, reduces contact resistance, has improved the useful life of isolating switch.
