In order to realize above-mentioned technical purpose, the utility model devises a kind of circuit breaker static contact mounting structure, and it includes
Pedestal and static contact, it is characterised in that：Magnetic inductive block is in pedestal, and the contact end of static contact is on magnetic inductive block, magnetic inductive block branch
The contact end of static contact is supportted, base is mounted in the back side of the pedestal, the contact end of the base support magnetic inductive block and static contact, institute
The installation end of static contact is stated outside the pedestal back side.
Further, the magnetic inductive block is in the groove of pedestal.
Preferably, the magnetic inductive block is U-shaped.
Further, the static contact includes contact end and installation end, and installation end is installed on outside the pedestal back side, described quiet
The contact end of contact stretches into base interior on magnetic inductive block from the installation via on pedestal, and the base is provided with boss from peace
Dress via, which is stretched into pedestal, to be propped up magnetic inductive block magnetic inductive block is played a supportive role, and the boss also support the contact end of static contact.
Preferably, the base screwed lock is outside the pedestal back side.
Preferably, the installation end screwed lock is outside the pedestal back side.
Beneficial effect
Contact of breaker is arranged on the pedestal back side by the circuit breaker static contact mounting structure that the utility model provides design
Outside, be advantageous to the installation and dismounting of static contact during breaker maintenance, it is not necessary to dismantle whole breaker from installation wall
Get off to be changed, directly disassembled from the breaker back side by static contact, while utilize magnetic inductive block support static contact, profit
Magnetic inductive block and static contact are supported with base, further improves the stability of circuit breaker static contact, avoids the contact of traditional static contact
Hold following hanging, static contact and moving contact produce fatigue after touching certain amount, and static contact can not reset, and reduce breaker point
The security of combined floodgate, the 3rd, it can rapidly promote moving contact and static contact contact production in the contact end increase magnetic inductive block of static contact
The quick blow-out of raw electric arc.Whole mounting means reduces the installation difficulty of static contact, has saved production cost, has extended open circuit
The service life of device.

Embodiment
With reference to the accompanying drawings and examples, the utility model is described in further details.
Embodiment 1
As shown in figure 1 and 2, a kind of circuit breaker static contact of the utility model mounting means is realized using conventional static contact
Mounting structure, it includes pedestal 1 and static contact 2, and in pedestal 1, the contact end 201 of the static contact 2 is mounted in be led magnetic inductive block 3
On magnetic patch 3.The magnetic inductive block 3 is U-shaped, and in order to spacing to magnetic inductive block 3, the present embodiment is devised the bottom of the magnetic inductive block 3
Structure in the groove 101 of pedestal 1, magnetic inductive block 3 support the contact end 201 of static contact 2, and base 4 is mounted in the pedestal 1
The back side, the base 4 supports the contact end 201 of magnetic inductive block 3 and static contact 2, and the installation end 202 of the static contact 2 is mounted in base
Outside 1 back side of seat.
Specifically, as shown in Figures 2 and 3, the static contact 2 includes contact end 201 and installation end 202, and installation end 202 is used
Screw one (accompanying drawing is not shown) is locked in outside the back side of pedestal 1, and the contact end 201 of the static contact 2 is from the installation via on pedestal 1
102 stretch into the inside of pedestal 1 on magnetic inductive block 3, and the base 4 is provided with boss 401 and stretched into from installation via 102 in pedestal 1
Prop up magnetic inductive block 3 to play a supportive role to magnetic inductive block 3, the boss 401 also support the contact end 201 of static contact 2.
The base 4 is locked in outside the back side of pedestal 1 with screw two (accompanying drawing is not shown).
During assembling, first static contact 2 is locked in outside the back side of pedestal 1 with screw one, is then again locked in base 4 with screw two
Outside the back side of pedestal 1, base 4 is provided with the head resigning hole of screw one.
As shown in Figure 4, the correspondence of static contact 2 of the moving contact 5 of each pole and each pole, as shown in figure 1 and 2, when need
When being overhauled to breaker, it is not necessary to by breaker integral demounting, it is only necessary to dismantled from the back side by static contact 2 from pedestal
Get off, simultaneously as there is the contact end that magnetic inductive block 3 supports static contact, base 4 limits magnetic inductive block 3, the contact of static contact 2
Elastic fatigue will not occur for end 201, in addition, the increase magnetic inductive block 3 of contact end 201 in static contact 2 can rapidly promote moving contact 5
The quick blow-out of caused electric arc is contacted with static contact 2.Whole mounting means reduces the installation difficulty of static contact, has saved production
Cost, extend the service life of breaker.
