Be in place of the structure main difference of contact assembly and existing contact assembly: current coil 2 and contact blade 3 it
Between be equipped with welded for realizing contact blade 3 and current coil 2 before pre-fix assembly pre-fix structure, pre-fix structure and include into
Pair the hook groove 22 that is assembled together of hook and L-type pendant 31, hook groove 22 and the interval circumferentially pairs of along contact blade of L-type pendant 31
Two pairs are evenly equipped with, also, hook groove 22 is arranged on the front end face of current coil 2, and L-type pendant 31 is then located at the rear end of contact blade
On face.Hook groove 22 has the translot section that cooperation is hooked with corresponding L-type pendant circumferentially extended along contact blade, and translot section, which has, to be supplied
The notch that L-type pendant 31 enters, L-type pendant 31 include vertical shank 312 and lateral hook portion 311, when assembly, make contact blade 3 with
Current coil 2 moves towards, and keeps the lateral hook portion 311 of L-type component 31 opposite with the notch entered for L-type pendant in hook groove 22
It answers, circumferentially rotates contact blade 3, enter the lateral hook portion of L-type pendant in the translot section of hook groove, realize hook groove and L-type pendant
Hook cooperation.
Also, due to the end face of the translot section slot bottom towards hook groove of the lateral hook portion 311 of all L-type pendants 31 and own
The groove bottom of the translot section of hook groove 22 is the cambered surface on same cylindrical surface, so, is cooperated in L-type pendant and hook groove
When, the end face of the translot section slot bottom towards hook groove 22 of the lateral hook portion 311 of all L-type pendants 31 and the translot of all hook grooves 22
The corresponding contact press of the groove bottom of section cooperates to limit radially to contact blade, the lateral hook portion of all L-type pendants
Groove bottom towards the translot section of the end face and all hook grooves of the translot section slot bottom of hook groove is to divide on above-mentioned hook groove and L-type pendant
It She You not be for corresponding to block press cooperation to carry out the radial positioning face of radial positioning to contact blade radially.
Two slot of front and back in the front and rear sides face of the lateral hook portion 311 of each L-type pendant 31 and the translot section of corresponding hook groove 22
The corresponding contact press cooperation of wall surface is upwards to limit contact blade in antero posterior axis, the front and back of the lateral hook portion of each L-type pendant
Two sides and two trough wall surface of front and back of the translot section of corresponding hook groove are to be respectively provided on above-mentioned hook groove and L-type pendant pair
Block press cooperation is answered to carry out the axial locating surface of axially position to contact blade upwards in antero posterior axis.
In the present embodiment, the tool of current coil 2 is formed between two coil segments 21 there are two coil segment 21 circumferentially
One end of two lower circumferential gaps, the corresponding lower circumferential gap of the direction of two coils is end, and two hook grooves are correspondingly arranged at two coils
End front position at, and the translot section of each hook groove for L-type pendant enter notch the corresponding of two coil segments is set
At terminal position, it is convenient for processing hook groove on current coil in this way.
Also, in the present embodiment, conducting rod is copper material, and contact is CuCr alloy, and the thermal expansion coefficient of conducting rod is big
In the coefficient of expansion of contact.
When assembly, by the corresponding front end for being mounted on current coil 2 of contact blade 3, when contact blade 3 and current coil 2 are opposite
When mobile assembly, contact blade 3 is circumferentially rotated, the lateral hook portion 311 on L-type pendant 31 enters in the translot section of hook groove, forms hook
Cooperation is hung, also, passes through the front and rear sides face of the lateral hook portion 311 of each L-type pendant 31 and the translot section of corresponding hook groove 22
The corresponding contact press cooperation of two trough wall surface of front and back passes through all L-type pendants 31 to limit upwards to contact blade in antero posterior axis
Lateral hook portion 311 the translot section slot bottom towards hook groove 22 end face and all hook grooves 22 translot section groove bottom correspondence connect
Touching press cooperation radially and axially realizes the positioning to contact blade, finally to limit radially to contact blade
That completes current coil and contact blade pre-fixes assembly.
In the case where welding high temperature, since the thermal expansion coefficient of current coil is greater than the thermal expansion coefficient of contact blade, it is arranged in electricity
Solder thawing of the streamline circle between contact blade effectively will be together with current coil and the reliable assemble welding of contact blade.It is welding
In termination process, contact blade is pre-fixed due to realizing, and contact blade will not be made deflection occur during pre-fixing and bring seam
One-step seal-exhaust welding effect is effectively ensured in gap.
In the present embodiment, radial positioning passes through the groove bottom of the end face of the lateral hook portion of L-type pendant and the translot section of hook groove
Cooperation in other embodiments, can also pass through the direction of the vertical shank of L-type pendant to form the radial positioning to contact blade
Corresponding end-faces press block cooperation at the respective side of L-type hook groove and the notch of hook groove is fixed to the radial direction of contact blade to realize
Position.
In the present embodiment, before the front and back sides of lateral hook portion and the translot section of hook groove that axially position passes through L-type pendant
Place's trough wall surface press cooperation is afterwards to form the axially position to contact blade, and in other embodiments, axially position can also pass through
Axially position of the press Planar realization for the other positions that hook groove and L-type pendant are equipped with to contact blade.
In the present embodiment, the coil segment for having current coil is two, lower part tool there are two lower circumferential gap, so hook groove and
L-type pendant is equipped with two pairs, in other embodiments, can also arrange two pairs or more, hook groove can also be arranged in other positions
Place.At this point, hook groove will include the vertical slot section extended along the longitudinal direction, which has enters for corresponding L-type pendant altogether
It is open-ended, also, vertical slot section is connected to the translot section of hook groove so that L-type pendant enters in translot section.It is corresponding, it can incite somebody to action
Hook groove and L-type pendant are arranged two pairs or more, but need to pay attention to circumferentially-spaced uniformly distributed along contact blade.
In the present embodiment, the contact body in contact assembly is current coil, and in other embodiments, contact body can also
Magnetic touching is indulged such as Authorization Notice No. for the vacuum interrupter disclosed in the Chinese utility model patent of CN201622971U to use
Cup-shaped coil on head.
The present invention also provides a kind of embodiment of vacuum interrupter, the structure of the vacuum interrupter in the embodiment with it is existing
The structure of vacuum interrupter in technology is largely identical, includes shell, moving contact component and static contact group is arranged in shell
Part, the difference with vacuum interrupter in the prior art essentially consist in: the dynamic touching in vacuum interrupter provided by the present embodiment
Head assembly and static contact component are all made of the structure of the contact assembly of above-mentioned arc-chutes, and details are not described herein.Certainly, in other realities
It applies in example, is also possible to moving contact component or static contact component uses the structure of above-mentioned contact assembly.
