Abstract
The utility model discloses a high -voltage direct -current relay draws forth end, including drawing forth the end, it is fixed mutually with the frame to draw forth the end, it is fixed with the stationary contact to draw forth the end lower extreme, the stationary contact is located the frame inboard, it is equipped with flux sleeve to draw forth the end overcoat, flux sleeve is made by the magnetic conduction material, flux sleeve is located between stationary contact and the frame. The utility model discloses a serve the flux sleeve who sets up the magnetic conduction material and make drawing forth, the heavy current when drawing forth the end, a magnetic conduction section of thick bamboo can produce suction to the movable contact spring, the movable contact spring rebound of being convenient for to the assurance is moved, the stationary contact reliably contacts.
Description
Technical field
This utility model relates to the exit of a kind of HVDC relay.
Background technology
The exit of HVDC relay fixes with stationary contact, movable contact fixes with movable contact spring, and movable contact spring and catch bar fix, relay is operationally, dynamic iron core is affected by magnetic forces with the catch bar being fixed on dynamic iron core to be moved up and down, so that the movable contact being fixed on movable contact spring contacts with stationary contact, separates.And dynamic iron core and catch bar move up, dynamic iron core and catch bar are the least by the active force of magnetic force, and i.e. moving thrust suffered when iron core moves upward from bottom to top can be more and more less.If dynamic iron core arrived too small by magneticaction power, then dynamic iron core and catch bar climb can be caused inadequate so that movable contact cannot contact with stationary contact, or movable contact and stationary contact loose contact.
Summary of the invention
The purpose of this utility model is to provide one, and to be easy to dynamic and static contact reliable, it is simple to the exit of the HVDC relay that exit is fixing with framework.
For achieving the above object, this utility model adopts the following technical scheme that the exit of a kind of HVDC relay, including exit, described exit fixes with framework, described exit lower end is fixed with stationary contact, and described stationary contact is positioned at inside framework, is arranged with flux sleeve outside described exit, described flux sleeve is made up of magnetic conductive material, and described flux sleeve is between stationary contact and framework.
This utility model is by arranging the flux sleeve that magnetic conductive material is made on exit, and when big electric current is by exit, magnetic conductive cylinder can produce suction to movable contact spring, it is simple to movable contact spring moves up, to ensure dynamic and static contact reliable contacts.
As preferably, described exit is formed with external screw thread, and described flux sleeve is formed with the female thread matched with described external screw thread, and described exit is screwed with described flux sleeve.
As preferably, described exit includes upper, middle and lower, described top is positioned at outside framework, the through hole that described framework is formed for the middle part of exit and bottom is passed through, described stationary contact is fixed on the downside of described bottom, described external screw thread forms the bottom with exit, and described flux sleeve is connected fixing so that exit fixes with framework with the lower thread of exit, and described flux sleeve upper surface offsets with described framework.This utility model realizes the fixing of exit and framework by flux sleeve and exit threaded engagement, framework is made to be clamped between exit top and flux sleeve, and the mode that this utility model exit is fixing with framework, fix with framework soldering compared with exit or the desired cost of mode that alternate manner is fixing is lower, it is possible to decrease the production and assembly cost of this utility model relay.
As preferably, flux sleeve is nut structure.
This utility model has to be easy to exit and framework and fixes, reduces the advantage of production and assembly cost, and this utility model also has the advantage that can improve movable contact with stationary contact contact reliability.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the exit of HVDC relay of the present utility model, including exit 1, exit 1 fixes with framework, exit 1 lower end is fixed with stationary contact 2, and framework forms by insulation board 3 with in the bracing frame 4 enclosing structure, and stationary contact 2 is positioned at insulation board 3 and the inner chamber 5 of bracing frame 4 formation, being arranged with flux sleeve 6 outside exit 1, flux sleeve 6 is between stationary contact 2 and insulation board 3.Insulation board 3 is made up of ceramic material, and bracing frame is made up of metal material, and flux sleeve 6 is made up of magnetic conductive material, and flux sleeve 6 is nut structure.
Exit 1 includes top 10, middle part 11 and bottom 12, top 10 is positioned at outside insulation board 3, the through hole that insulation board 3 is formed for the middle part 11 of exit 1 and bottom 12 is passed through, the middle part 11 of exit is positioned at through hole, stationary contact 2 is fixed on the downside of bottom 12, and bottom 12 is formed with external screw thread, flux sleeve 6 is formed with the female thread matched with external screw thread.
Flux sleeve 6 and exit 1 threaded engagement, and make flux sleeve 6 upper surface offset with insulation board 3 lower surface, insulation board 3 can be made to be limited between top 10 and flux sleeve 6, thus complete the fixing of exit 1.
When big electric current passes through, flux sleeve 6 can produce suction to movable contact spring 7, it is simple to movable contact spring 7 moves up, to ensure dynamic shake-up 8 and stationary contact 2 reliable contacts.
