Description
Technical field
The present invention relates to a kind of electric switch namely breaker.
Background technology
, there are following some defects in existing electric switch：First, N poles are not provided with arc initiation device, when switch breaking current
When, because electric arc can not guide to other positions or arc-chutes from moving contact and static contact, cause switch dynamic/static contact scaling loss serious,
Even if or be provided with arc initiation device, but be not provided with arc-chutes, cause electric arc to be stagnated for a long time in arc initiation device, cause product to burn
Phenomenon is ruined or bursts, because general circuit N poles can not disconnect, but above-mentioned switch product, because dynamic/static contact scaling loss effectively causes electricity
Gas short life, causes line broken circuit failure and other harm, can not meet market demands；2nd, L is extremely typically gone out using less
Arc chamber, or using upper and lower asymmetric arc-chutes, partly electric arc cannot introduce arc-chutes caused by striking passage is small, cause
Switch product breaking capacity is low or bursts phenomenon, can not meet the higher and higher requirement of circuit breaking capacity；3rd, L poles, N is extremely moved
Contact is separately fixed at L poles, on the moving contact rack of N poles, then L poles, N poles moving contact rack are arranged on the both sides of lever, lock
It is also disposed on lever with tripping, now organization volume is big, and mechanism kinematic is dumb, breaking speed is slow, L poles, N poles moving contact point
Not Wei Yu middle seat both sides up and down, be arranged on the both sides of lever because of L poles, N poles moving contact rack, mechanism section L poles can not with N poles
Isolation, electric arc and the easy short circuit of gaseous conductor cause product to burst during disjunction high current makes product disjunction fail.And exist and divide
Have no progeny the pressure-resistant risk for puncturing, it is impossible to meet user's use requirement.
The content of the invention

L poles contact operating device includes L poles moving contact, tripping, L poles moving contact rack, latch spring, lock and the first drawing
Spring, wherein L poles moving contact are fixedly installed on moving contact rack, and long through-hole is provided with the moving contact rack of L poles, are set in long through-hole
Bearing pin is equipped with, the two ends of the bearing pin are arranged on the middle seat and upper lid of electric switch, described first extension spring one end is connected to L and extremely moves
On contact supporting, and the top of long through-hole is located at the tie point of L poles moving contact rack, the other end of the first extension spring is fixedly connected
On the miscellaneous part being fixedly connected on middle seat or with middle seat, the tripping is hinged the upper end for being arranged on L poles moving contact rack, jumps
Connected by first connecting rod between button and the handle of electric switch, the lock middle part is movably set in pin by the through hole for setting
On axle, lock top is extended to have can contradict the conflict pin for coordinating limitation tripping to rotate with tripping, and the lock lower section is set
There are promotion pin and resetting pin, wherein promoting pin to be correspondingly arranged with trip gear push rod, the top ends of the resetting pin are provided with bullet
Spring abutment, described latch spring one end is contradicted on spring base, it is characterised in that：The contact operation of N poles is provided with second placing chamber
Device, N poles contact operating device includes N poles moving contact, the second extension spring, connecting shaft and contradicts pin, and the connecting shaft is put
In elongated hole above middle seat, connecting shaft is connected to the top of N poles moving contact and L poles moving contact rack, in the moving contact of the N poles
Portion is provided with arc resistance surface, and the conflict pin is arranged between middle seat and base, and is correspondingly arranged with arc resistance surface, N poles
The arc resistance surface top of moving contact is provided with connecting hole or connection boss, and second extension spring one end is connected to connecting hole or connects convex
On platform, the other end is connected on middle seat or base, and the N poles moving contact lower end is contact.
By using such scheme, the product can also make N poles when L poles contact operating device goes wrong very well
Disconnect, the need for so meeting special occasions, wherein N poles contact operating device includes N poles moving contact, the second extension spring, connection
The plan of establishment of axle and conflict pin, can so realize the excess of stroke function of N poles moving contact by the second extension spring, imitate contact
More preferably, N poles contact operating device is closed between L poles contact operating device closure to fruit in the present embodiment in addition, after disconnection
Disconnect, these actions in the field be also it is conventional, it is described herein we be just not described in detail.
The further setting of the present invention is：L poles arc-control device is included under L poles arc-chutes, L extremely go up run-on tab, L extremely
The ultra-Left flash barrier of run-on tab, L and the ultra-Right flash barriers of L, the nock that enters of the arc extinguishing front edge of board of L poles arc-chutes are arranged on end face
Middle part, arc extinguishing front edge of board is located at the part into nock both sides into being symmetrical arranged, and the ultra-Left flash barriers of L and the ultra-Right dividing plates of L are located at
Enter the left and right sides at nock, on the ultra-Left flash barriers of L and the ultra-Right flash barriers of L near the part entered at nock for left arc face and
Right arc face, the left arc face and right arc face are close to parallel or be arranged in parallel.
By using such scheme, the system striking and arc quenching effect can be made more preferably, be in particular in：The L polar arcs
The arc extinguishing front edge of board of room enters the middle part that nock is arranged on end face, and arc extinguishing front edge of board is located at part into nock both sides into symmetrically setting
Put, can so compare into the gas and electric arc in the arc-chutes of L poles and be evenly distributed in each space in L poles arc-chutes inside, so
Do not result in that partial pressure in arc-chutes is too high and the problem that bursts；2nd, the ultra-Left arc faces of L and the ultra-Right arc faces of L are close to parallel
Or be arranged in parallel, so it is more beneficial for electric arc to introduce L poles arc-chutes, and it is more steady to enter the pressure at nock, makes electric arc
Be conducive to uniform respectively in each space of arc-chutes of L poles.
The present invention is further set：N poles arc-control device, N poles arc-control device bag are additionally provided with second placing chamber
Include N and extremely gone up run-on tab, N and extremely descend run-on tab and N poles arc-chutes, wherein N extremely to go up run-on tab by overhead gage portion, upper striking portion and connect
Line portion is wholely set composition, and N extremely descends run-on tab to be wholely set and constituted by contact part, lower striking portion and lower block plate portion, upper striking portion
Striking road is constituted and lower striking portion between, N poles arc-chutes include arc extinguishing dividing plate and supporting plate, and wherein supporting plate is fixed and set
Put in the both sides of arc extinguishing dividing plate, the front center of arc extinguishing dividing plate is provided with V-arrangement and enters nock, this enters nock alignment striking road and sets.
By using such scheme, we can further protect electric switch not by arc through or blow, main table
The N poles of present electric switch are provided with N poles arc-control device, once the extremely powered generation electric arcs of so N, thus can be by N poles
