Referring to FIG. 1, a kind of static contact connection component 1, including connecting plate 10, static contact 20, connection bolt and support
Part 30.
The connecting plate 10 is connected with the static contact 20 by the connection bolt (not shown), the support element 30
It is connected in the connection stud base, and with the connection bolt thread.The stability of static contact 20 is kept by support element 30,
Support element 30 with connect bolt thread dismounting easy to connect.
Referring to FIG. 2, the connecting plate 10 includes contact interconnecting piece 11, bending part 12 and conductor successively from left to right
Interconnecting piece 13.Contact interconnecting piece 11, bending part 12 and conductor coupling portion 13 are integrally formed, and contact interconnecting piece 11 is equipped with and quiet
The connecting hole (not shown) that contact 20 connects, conductor coupling portion 13 are equipped with the connecting hole (not shown) connected with external conductor.
The bending part 12 is extended by the endwise side bending of the contact interconnecting piece 11 so that bending part 12
At an angle with contact interconnecting piece 11, and with the continuing to extend of bending part 12 it is partly staggered in the straight line of contact interconnecting piece 11
Extending direction.
The conductor coupling portion 13 is extended by the bending of the bending part 12 end, and the conductor coupling portion 13 is prolonged
It is parallel with the linear extension direction of the contact interconnecting piece 11 to stretch direction.
In the present embodiment, the bending part 12 is equipped with shunting through-hole 121.When electric current is from 121 both sides of shunting through-hole
When flowing through, the electric current flowed through, which is divided into two parts, makes every portion of electrical current reduce, to reduce the Wen Sheng on contact connecting plate 10,
The shunting through-hole 121 can also save material, reduce production cost, increase heat-dissipating space.
It is unsuitable wide to shunt through-hole 121, wide shunting through-hole 121 can cause the cross-sectional area of connecting plate 10 to become smaller, from
And increase unit area by electric current, and then cause connecting plate 10 by super-high-current ablation.Therefore, in the present embodiment, institute
State shunting through-hole 121 be in strip, and it is described shunting through-hole 121 length direction and the bending part 12 extending direction phase
Together.So that the shunting through-hole 121 is that will not reduce the cross-sectional area of connecting plate 10, while the heat dissipation of connecting plate 10 can be increased
Space.
The bending part 12 is extended by the endwise side bending of the contact interconnecting piece 11, i.e. 12 He of bending part
Between contact interconnecting piece 11 in obtuse angle, it between obtuse angle is 90 °~180 °, can arbitrarily select, can play drop low-temperature-rise
Effect.
Wherein preferred, the angle of the bending part 12 and the conductor coupling portion 13 is between 130 °~160 °.130°
Under, bending part 12 excessively roll over outwardly by lateral bending, leads to occupy that horizontal space is excessive, does not meet the requirement of breaker miniaturization.
160 ° or more, the linear extension direction of bending part 12 and contact interconnecting piece 11 is staggered very few, is unfavorable for increasing heat-dissipating space.
It is furthermore preferred that the bending part 12 and the angle of the conductor coupling portion 13 are between 134 °~140 °.This folder
In angular region, the bending part 12 can be under the length range for keeping connecting plate 10, and be maximumlly staggered contact interconnecting piece 11
Linear extension direction, and meet breaker miniaturization space requirement.
On the other side, the contact interconnecting piece 11 is of same size with the conductor coupling portion 13, the contact connection
The length ratio of the width in portion 11 and the bending part 12 is 1：0.5~0.7.The i.e. described conductor coupling portion 13 connects with the contact
The length direction of socket part 11 be staggered 1/3~2/3 degree.To increase heat-dissipating space, and increase each phase end of breaker it
Between phase spacing.
Referring to FIG. 3, the support element 30 includes nut 31 and insulating plug 32；The nut 31 and the connection spiral shell
Bolt is adapted, and the nut 31 is sheathed in the insulating plug 32.Insulating plug 32 plays the role of electrically isolating.The insulating plug
32 are made of insulated heat materials, avoid the heat transfer of breaker other parts to 20 connection component 1 of static contact.
As a further improvement, the insulating plug 32 includes a plug slot 321 and bottom plate 322, the bottom plate 322 is set to institute
321 bottom of a plug slot, the bottom plate 322 with breaker for connecting；The a plug slot 321 is the groove that side wall is undulated structure,
The groove is interference fitted with 31 phase of the nut, to abundant clamping nut 31.
Referring to FIG. 4, the utility model also provides a kind of static contact connection system comprising two groups of stationary contacts as described above
First 20 connection component 1 and one group of linear type contact connection component 2, the linear type contact connection component 2 are located at described in two groups
Between 20 connection component 1 of static contact；The connecting plate of the linear type contact connection component 2 is rectilinear plate, stationary contact described in two groups
The connecting plate 10 of first 20 connection component 1 is bent towards the side far from the linear type contact connection component 2 respectively.
In static contact connection system, pass through 20 connection component 1 of this static contact and common linear type contact connection component 2
Cooperation, can increase the phase spacing of breaker, to increase its insulation distance, avoid the phase fault of breaker.Here
" phase " refers to three-phase symmetrical AC power, the power-supply system being made of three single phase alternating current power supplies.If adjacent contact connects
Distance is too short between socket part 11, and when the electric current of contact interconnecting piece 11 is excessive, electric current can break up air, cause phase fault.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
