Description
Technical field
The utility model relates to high-voltage switch field, is specially a kind of switch cubicle disconnecting link assembly.
Background technology
At present, there is following problem when installing and use in switch cubicle disconnecting link assembly:
1, when nut used after mounting by disconnecting link disc spring group assembly, in order to ensure correct closing retention force, need to measure with special tooling the decrement whether disc spring group reaches setting, this process is more time-consuming, and measurement is with eye-observation, cannot ensure the consistency of correctness and different disconnecting link assembly decrement completely.
2, disconnecting link assembly disc spring group and nut expose, and its sharp edge easily causes point discharge, reduce equipment withstand voltage properties.
Utility model content
The purpose of this utility model solves above-mentioned two technical problems, provides a kind of switch cubicle disconnecting link assembly, and this disconnecting link assembly effectively can reduce installation time when the correct closing retention force of guarantee disconnecting link, and can reduce the point discharge of disconnecting link.
The technical scheme realizing above-mentioned purpose is: switch cubicle disconnecting link assembly, comprise movable touch knife, movable touch knife is made up of two blades, the rear end of two blades connects disconnecting link contact by rear bolt, the front end of two blades is connected by front bolt, it is characterized in that: described front bolt is identical with the structure of rear bolt, comprise screw shell, screw rod, disc spring group and bowl-type shielding cap, two blades are crossed after described screw shell is connected with screw flight, the outer end of screw shell and screw rod is respectively arranged with annular boss, screw shell, screw shell between the annular boss of screw rod and the blade of respective side and screw rod have placed disc spring group respectively, the outer end of screw shell and screw rod is also connected to the bowl-type shielding cap that opening is oppositely arranged, screw shell between two blades of described front bolt and screw rod have placed disconnecting link spacer, and described disconnecting link contact is connected on screw shell between two blades of rear bolt and screw rod.
When above-mentioned screw rod and threaded sleeve screw, the disc spring group decrement on screw shell and screw rod reaches set point.
Also be threaded in above-mentioned screw shell holding screw, and the one end being pressed in screw rod and being connected with screw shell is pushed up in one end of holding screw, ensures that screw rod is connected with the reliable of screw shell.
The beneficial effects of the utility model:
1, the utility model, avoids point discharge phenomenon by shielding cap by disc spring group parcel therein.
2, the length that is threaded when the utility model screws with threaded sleeve by controlling screw rod, makes the disc spring group decrement on screw shell and screw rod reach set point, effectively can improve efficiency of assembling, increase economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A portion enlarged drawing in Fig. 2.
Embodiment
As shown in Figure 1, 2, 3, the utility model comprises movable touch knife 1, and movable touch knife 1 is made up of two blades 2, and the rear end of two blades 2 connects disconnecting link contact 4 by rear bolt 3, and the front end of two blades 2 is connected by front bolt 5.
Front bolt 5 is identical with the structure of rear bolt 3, comprise screw shell 6, screw rod 7, disc spring group 8 and bowl-type shielding cap 9, screw shell 6 crosses two blades 2 after being threaded with screw rod 7, screw shell 6 is respectively arranged with annular boss 10 with the outer end of screw rod 7, on screw shell 6 between the annular boss 1 of screw shell 6 and the blade 2 of respective side, and screw rod 7 between the annular boss 1 of screw rod 7 and the blade 2 of respective side has placed disc spring group 8 respectively, screw shell 6 and the outer end of screw rod 7 are also threaded the bowl-type shielding cap 9 that opening is oppositely arranged respectively.
Screw shell between two blades of front bolt 56 and screw rod 7 have placed disconnecting link spacer 11, and the screw shell 6 between two blades 2 that disconnecting link contact 4 is connected to rear bolt 3 is with on screw rod 7.
When screw rod 7 and threaded sleeve 6 screw, disc spring group 8 decrement on screw shell 6 and screw rod 7 reaches set point.
Also be threaded in screw shell 6 holding screw 12, and the one end being pressed in screw rod 7 and being connected with screw shell 6 is pushed up in one end of holding screw 12.
