Description
Technical field
The present invention relates to relay technical fields, more particularly to a kind of high voltage direct current relay with microswitch.
Background technology
Relay, which is usually graded by magnetic circuit part, contact portion, promotion part and lead division, to be formed, wherein magnetic circuit part master
Componental movement is pushed if converting electrical energy into mechanical energy and driving, so that contact portion is contacted, to have the function that ON/OFF.
A kind of high voltage direct current relay with microswitch of the prior art is to use direct-acting magnet line structure, this straight
The catch bar of the promotion part of current relay is mutually fixed with dynamic iron core, and when the coil is energized, dynamic iron core movement drives catch bar
Movement, one end of catch bar are equipped with movable contact spring, and catch bar drives movable contact spring movement so that movable contact spring and are fixed on corresponding position
Stationary contact is in contact, and when the coil is de-energized, catch bar and dynamic iron core reset under the drive of resetting spring so that movable contact spring with it is quiet
Contact is separated, to play the purpose for switching on and off circuit.This high voltage direct current relay also carries microswitch, Fig. 1
For a kind of local structure schematic diagram of high voltage direct current relay with microswitch of the prior art, the high voltage direct current relay packet
Include catch bar 100, movable contact spring 200, sliding set 300 and microswitch 400；Sliding set 300 and movable contact spring 200 are inserted in promotion respectively
In bar 100, a clamp spring 101 is fixed on one end of catch bar 100 with for realizing the limit to sliding set 300, catch bar 100
The other end is then used for connecting dynamic iron core, and catch bar 100 is equipped with reducing step, and contact spring 201 is mounted in the reducing platform of catch bar 100
Between rank and movable contact spring 200, contact spring 201 is by movable contact spring 200 by 300 ejection of sliding set to clamp spring 101, microswitch
400 is in relay and corresponding in the side of sliding set 300, and sliding set 300 is equipped with poke rod 301, poke rod 301 to side
End matched with the swing arm 401 of microswitch 400, when catch bar 100 moves upwards, catch bar 100 passes through contact bullet
Spring 201 drives sliding set 300 to move upwards, and sliding set 300 then compresses the dynamic of microswitch 400 by the end of poke rod 301
Arm 401 makes microswitch 400 be closed.The end of the relay of this structure, poke rod 301 is pushing swing arm 401 up to connect
Always by swing arm 401 to its reaction force (downward for direction) while high-tension circuit, in this way, sliding set 300 is touched with dynamic
It is a degree of crooked that the mode of 200 face of piece contact necessarily causes movable contact spring 200 to generate, if relay longevity of service,
Movable contact spring 200 is crooked will cause relay can not normal reset cause security risk to influence product performance.
Invention content
It is an object of the invention to overcome the deficiency of the prior art, a kind of high voltage direct current relay with microswitch is provided
