Description
Technical field
The invention belongs to electrical equipment, and in particular to a kind of rotary AC contactor arc-extinguish chamber fixed structure.
Background technology
Arc-extinguish chamber is the core component of contactor product, and the fixation of rotary contactor arc-extinguishing chamber is than direct-acting contactor
Difficulty is big.Existing rotary contactor arc-extinguishing chamber is after installing, and fixed defective tightness, can rock when manual, and contactor exists
During work, impact vibration is very big, is easy to come off during long-time use, and arc extinguishing energy is lost once the contactor that comes off
Power, may cause accident, therefore it is particularly important that the fixation of arc-extinguish chamber on the contactor.Such as going out for CJ12 rotary AC contactors
Arc cover fixed structure is：The connection of left and right two halves arc-extinguish chamber be two ends respectively with two axis connections, the spindle nose two on top
End is respectively provided with two spring steel wires, i.e. one end of spring steel wire is fixed on spindle nose.Arc-extinguish chamber is inserted in both sides magnetic conduction during assembling
Between plate, the shape of magnetic conductive board has the shape in the middle part of the circular arc and arc-extinguish chamber of two stretchings to cooperate, but is not closely to match somebody with somebody
Close, have a convex hook respectively on the outermost clamping plate of both sides magnetic conductive board, two spring steel wires are hooked in convex hook respectively, and spring steel wire is another
End is lived with the spindle nose shelves of arc-extinguish chamber lower part.The centre of both sides magnetic conductive board is fixed on the both ends of arc blow-out iron core with fastener respectively, leads
The punching of clamping plate lower end has a rectangular v notch v on the outside of magnetic sheet, is inserted on the rectangle boss of plastic feet, by the two sides of boss
Fixation is played in contact surface and gap.Because the contact surface length of side of boss is shorter, and need to leave certain gap, therefore this part
It can teeter when manually.Arc-extinguish chamber is movable in itself, is fixed not plus magnetic conductive board mainly by the fixation that mounts of spring steel wire
Jail, when contactor works, arc-extinguish chamber can wave, and the other end of spring steel wire also has the possibility of slippage.Other AC and DCs connect
The fixed structure of tentaculum arc-extinguish chamber is similar.
The content of the invention
To solve the problems, such as that existing rotary AC contactor arc-extinguish chamber fixes a kind of unstable, structure letter of present invention offer
List, firmly install, be convenient for disassembly and assembly, the rotary AC contactor arc-extinguish chamber fixed structure that shock resistance is good, functional reliability is high.

The arc-extinguish chamber modular construction that magnetic conductive board 2 forms is inserted on the pedestal that base 5, stent 6 and blowout coil iron core 7 form.Latch fitting 3
U-shaped in the form of sheets, its top rivet interlacement are installed on 3 bottom 3a of latch fitting and arc extinguishing in arc-extinguish chamber 1 close to bottom position, spring 4
Cover in the gap between 1 bottom.Latch fitting 3 can be rotated around rivet, and 3 bottom 3a of latch fitting is made under 4 elastic reaction of spring vertically downward,
4 elastic force of spring need to be overcome by being moved with hand when latch fitting 3 is turned out.2 lower end of magnetic conductive board is equipped with downward bar shaped extension 2b and groove
2a.Two 6 back-end locations of stent are equipped with raised triangle convex mouth 6b, and are equipped with downward bar shaped guide groove 6a, its groove width is with leading
The width of 2 bar shaped extension 2b of magnetic sheet is adapted.During installation, arc extinguishing shade assembly is inserted in downwards on base 5,2 lower end of magnetic conductive board
Groove 2a be plugged on 7 both ends of iron core, in bar shaped extension 2b insertion bar shaped guide grooves 6a, latch fitting 3 rotates when crossing convex mouth 6b, to convex
Mouth 6b insertions latch fitting 3U shapes reset when curved interior, and 3 bottom 3a of latch fitting is held in convex mouth 6b bottoms, and whole arc extinguishing shade assembly is pinned.
When taking arc extinguishing shade assembly, 3 bottom 3a of latch fitting is outwards removed, you can extract arc extinguishing shade assembly upwards.
In the above-mentioned technical solutions, two 2 inner side interplanar distances of magnetic conductive board are slightly less than two 6 outside interplanar distances of stent, make to go out
After arc cover component inserted base 5,2 medial surface of magnetic conductive board is close to 6 lateral surface of stent, prevents 1 double swerve of arc-extinguish chamber.Iron core 7
Both ends are fixed with catch 7b, when the groove 2a for 2 lower end of magnetic conductive board is plugged on 7 both ends of iron core, stop that magnetic conductive board 2 outwards struts,
Magnetic conductive board 2 is set to be bonded with stent 6 closely.
Beneficial effect：
The present invention uses arc-extinguish chamber connected structure, simple in construction, easy to disassemble and assemble.The groove 2a of magnetic conductive board lower end, bar shaped extend
Portion 2b and the latch fitting 3 equipped with spring, respectively with 7 both ends of iron core on pedestal, bar shaped guide groove 6a and the close grafting of convex mouth 6b, and
Iron core both ends are equipped with catch, by whole arc extinguishing shade assembly fixation, effectively prevent that arc-extinguish chamber is rocked or come off during operational vibration,
Magnetic conductive board is contacted with blowout coil iron core at the same time closely, ensure that good magnetic conductivity, solve the prior art well not
Foot, effectively increases arc-extinguish chamber functional reliability.
