It crosses elastic component to connect with moving contact, the conflict column is mobile with moving contact and contradicts with the second static contact.
By using above-mentioned technical proposal, moving contact is overturn along hinged place, will contradict column and the second static contact contradicts, produce
Raw mutual pressure makes to contradict the direction movement of column toward close connector sleeve, and contradicts conflict column and connector sleeve, the heat of generation
It is exported from heat release hole, heat radiation, it is mobile toward the direction far from the second static contact when moving contact, pass through the elastic force of elastic component
Effect will contradict column and separate with connector sleeve, so that heat is exported from the end of connector sleeve, significant increase heat dissipation effect.
The utility model is further arranged to: the conflict column is hemispherical close to one end of the second static contact.
Frictional dissipation can be reduced when contradicting column and the second static contact contradicts by using above-mentioned technical proposal, extended
The service life of column is contradicted, meanwhile, when contradicting column toward close to the movement of the direction of the second static contact, hemispherical surface can be passed through
Guiding function, be convenient for and the second static contact contradict.
The utility model is further arranged to: the moving contact offers slot segmentation along the length direction of itself.
By using above-mentioned technical proposal, the heat dissipation area of moving contact, further improving radiating effect are increased.
The utility model is further arranged to: the slot bottom of the slot segmentation is in arc-shaped.
By using above-mentioned technical proposal, the slot bottom of slot segmentation is avoided stress concentration occur, can adapt to the frequency of moving contact
It is numerous folding and be not susceptible to be broken.
The utility model is further arranged to: offering lead-in chamfered on the side wall of second static contact.
By using above-mentioned technical proposal, by the guiding function of lead-in chamfered, convenient for column and the second static contact will be contradicted
Surface contradict, promoted operational reliability.
The utility model is further arranged to: the conflict column includes the connecting rod being mutually permanently connected and for the
The terminal pad that two static contacts contradict, the connecting rod are threaded with location nut, the location nut and moving contact
Outer wall contradicts.
Pass through the elastic force of elastic component in the moment that conflict column is separated with the second static contact by using above-mentioned technical proposal
Effect contradicts column toward the direction movement far from moving contact, contradicts the outer wall of location nut and moving contact, will contradict column limit,
Conflict column is set to be not easy to deviate from from moving contact.
In conclusion the utility model has the following beneficial effects:
Moving contact contradicts conflict column and the second static contact, then makes to contradict toward close to the movement of the direction of the second static contact
Column is contradicted by the effect of the pressure of the second static contact with connector sleeve, and the heat of generation is exported from heat release hole, meanwhile, slot segmentation into
One step increases the heat dissipation area of moving contact, to achieve the effect that convenient for heat dissipation.
