Abstract
An insulation barrier and arc-extinguishing type electric appliance switch contact head is disclosed and is used in the high-low voltage power supply and consumption field. A static contact head wire connecting end is mounted at a tail end of a static contact head and is connected with a power source through a lead wire, static contact head insulating bodies are mounted at front ends of the static contact head, a moving contact head wire connecting end is mounted at a tail end of a moving contact head and is connected with a load through a lead wire, and a moving contact head insulating body is mounted at a front end of the moving contact head. When the contact head is closed, the moving contact head is plugged into the static contact head. Before the moving contact head and the static contact head are closed, the moving contact head insulating body and the static contact head insulating bodies are closed, and therefore the moving contact head is isolated from the static contact head in an insulated manner, and electric discharge can be prevented between the moving contact head and the static contact head and electric arcs can be prevented. When the contact head is separated, the moving contact head is drawn out from the static contact head. After the moving contact head is separated from the static contact head, the moving contact head insulating body and the static contact head insulating bodies are closed, and therefore the moving contact head is isolated from the static contact head in an insulated manner, and electric discharge can be prevented between the moving contact head and the static contact head and the electric arcs can be prevented.
Description
Technical field
The utility model provides a kind of and has stopped arc extinguishing formula electric appliance switch contact at high-low pressure for the insulation of using with electrical domain.
Background technology
At present, electric appliance switch contact is very extensive for using with electrical domain at high-low pressure.In order to knock out the appliance switch electric arc that contact produces when conducting or the deenergization, standing in the appliance switch have arc control device or arc-extinguishing medium be housed.The volume of appliance switch but also complex structure, cost of manufacture height have so not only been increased.
Summary of the invention
In order to overcome the big and high deficiency of complex structure cost of manufacture of existing appliance switch volume.The utility model provides a kind of insulation to stop arc extinguishing formula electric appliance switch contact.This insulation stops that arc extinguishing formula electric appliance switch contact adopts insulator to cover the mode of blocking contact and carries out arc extinguishing, and arc quenching effect simple in structure is good and cost of manufacture is cheap.
The technical scheme that its technical problem that solves the utility model adopts is: this insulation stops that arc extinguishing formula electric appliance switch contact mainly contains each several parts such as fixed contact, fixed contact terminals, static contact and insulation body, moving contact, moving contact insulator, moving contact terminals and constitutes.The tail end that the fixed contact terminals are installed in fixed contact is connected with power supply through lead, is equiped with the static contact and insulation body at the front end of fixed contact; The tail end that the moving contact terminals are installed in moving contact is connected with load through lead, is equiped with the moving contact insulator at the front end of moving contact.When contact closure, moving contact inserts to fixed contact, and before moving contact and fixed contact closure, moving contact insulator and static contact and insulation body closure are isolated insulation between moving contact and the fixed contact, stop discharge generation electric arc between moving contact and the fixed contact.When the contact disjunction, moving contact is extracted out from fixed contact, has no progeny at moving contact and fixed contact branch, and moving contact insulator and static contact and insulation body closure are isolated insulation between moving contact and the fixed contact, stop discharge generation electric arc between moving contact and the fixed contact.
The beneficial effects of the utility model are that when contact closure, moving contact inserts to fixed contact, before moving contact and fixed contact closure, moving contact insulator and static contact and insulation body closure are isolated insulation between moving contact and the fixed contact, stop discharge generation electric arc between moving contact and the fixed contact.When the contact disjunction, moving contact is extracted out from fixed contact, has no progeny at moving contact and fixed contact branch, and moving contact insulator and static contact and insulation body closure are isolated insulation between moving contact and the fixed contact, stop discharge generation electric arc between moving contact and fixed contact.

Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is schematic diagram after the contact closure
Fig. 3 is the contact branch schematic diagram of having no progeny
" 1 " fixed contact terminals in Fig. 1, " 2 " fixed contact, " 3 " static contact and insulation body, " 4 " moving contact insulator, " 5 " moving contact, " 6 " moving contact terminals
Embodiment
In Fig. 1, the tail end that fixed contact terminals " 1 " are installed in fixed contact " 2 " is connected with power supply through lead, is equiped with static contact and insulation body " 3 " at the front end of fixed contact " 2 "; The tail end that moving contact terminals " 6 " are installed in moving contact " 5 " is connected with load through lead, is equiped with moving contact insulator " 4 " at the front end of moving contact " 5 ".When contact closure, moving contact " 5 " inserts to fixed contact " 2 ", before moving contact " 5 " and fixed contact " 2 " closure, moving contact insulator " 4 " and static contact and insulation body " 3 " closure, insulation between moving contact " 5 " and the fixed contact " 2 " is isolated, stopped between moving contact " 5 " and the fixed contact " 2 " to produce electric arc.When the contact disjunction, moving contact " 5 " is extracted out from fixed contact " 2 ", have no progeny at moving contact " 5 " and fixed contact " 2 " branch, moving contact insulator " 4 " and static contact and insulation body " 3 " closure, insulation between moving contact " 5 " and the fixed contact " 2 " is isolated, stopped between moving contact and the fixed contact to produce electric arc.
Claims (3)
1. one kind stops arc extinguishing formula electric appliance switch contact at high-low pressure for the insulation of using with electrical domain, is made up of fixed contact, static contact and insulation body, moving contact, moving contact insulator each several part, and it is characterized in that: the static contact and insulation body is installed in the fixed contact front end; The moving contact insulator is installed in the moving contact front end.
2. insulation according to claim 1 stops arc extinguishing formula electric appliance switch contact, it is characterized in that: before moving contact and fixed contact closure, moving contact insulator and static contact and insulation body closure are isolated insulation between moving contact and the fixed contact.
