Description
Technical field
The utility model provides a kind of conducting rod of vacuum interrupter, belongs to conducting rod field.
Background technology
Connection between the conducting rod of current vacuum interrupter and contact combinations, generally adopts nature contact to connect, or the structure of being made of one; In Nature Link technique, cup, support, contact will be combined and will first weld, then with conducting rod connecting welding, production efficiency is low, and energy consumption is high; The structure be made of one, complex structure, stock utilization is low.
Utility model content
The utility model object is the conducting rod providing a kind of vacuum interrupter, effectively improves the production capacity of equipment, reduces energy consumption, shortens the production cycle, improve production efficiency.
The conducting rod of vacuum interrupter described in the utility model, comprise conducting rod and contact combinations, contact combinations comprises contact, cup and support, conducting rod is provided with projection, projection is provided with hole, the inwall in hole is provided with screw thread, cup is provided with hole A, the size of hole A adapts with protruding size, on support, the position of corresponding aperture is provided with hole B, on contact, the position of corresponding aperture is provided with hole C, be provided with stud, stud is through hole A, hole B and hole C, and with the threaded engagement in hole, stud is provided with through hole, contact, cup, between support and conducting rod, touching position is provided with welding material.
The conducting rod of described vacuum interrupter, the projection of conducting rod and the hole A shape of cup adapt, make projection just can in access aperture A, can for play fixing effect between conducting rod and cup, together with conducting rod to be directly connected to contact combinations by stud by the utility model, and between the part contacted with each other, put welding material in advance, make conducting rod and the disposable welding fabrication of contact combinations, effectively improve the production capacity of equipment, reduce energy consumption, shorten the production cycle, improve production efficiency, and use hollow screw, avoid gas not divisible.
The conducting rod of described vacuum interrupter, stud is countersunk head stud, and hole B is truncated cone-shaped, and adapts with the countersunk shape of countersunk head stud.The counter sink portion of stud can be hidden in the B of hole completely, avoid it and expose and cause contact surface out-of-flatness.
The conducting rod of described vacuum interrupter, the hole on conducting rod is positioned at conducting rod center.Hole is positioned at center, makes the utility model each several part stress equalization, also makes structure more stable.
The utility model compared with prior art beneficial effect is:
The conducting rod of described vacuum interrupter, the projection of conducting rod and the hole A shape of cup adapt, make projection just can in access aperture A, can for play fixing effect between conducting rod and cup, together with conducting rod to be directly connected to contact combinations by stud by the utility model, and between the part contacted with each other, put welding material in advance, make conducting rod and the disposable welding fabrication of contact combinations, effectively improve the production capacity of equipment, reduce energy consumption, shorten the production cycle, improve production efficiency, and use hollow screw, avoid gas not divisible.
Described stud, makes the counter sink portion of stud be hidden in completely in the B of hole, avoids it and exposes and cause contact surface out-of-flatness.
Described hole, hole is positioned at center, makes the utility model each several part stress equalization, also makes structure more stable.
