Description
Technical field
The utility model relates to a kind of contact of primary cut-out.
Background technology
Primary cut-out (or claim high-voltage switch gear) not only can cut off or no-load current in closed high circuit and load current; and when system jam by the effect of relay protection; cut off overload electric current and short circuit current; it has quite perfect arc extinguishing structure and enough cutout abilities, can be divided into: oil circuit breaker (bulk-oil circuit-breaker, oil-minimum breaker), sulfur hexafluoride breaker (SF6 circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.Contact is the core component of the electric switch-on part in primary cut-out, and existing contact is fixing not firm, and easily occur to loosen, useful life is short.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of contact of primary cut-out, and the contact of this primary cut-out is fixed, is less likely to occur to loosen, and improves useful life.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of contact of primary cut-out, comprise head, middle part, step, afterbody, head and integral middle shaping, step is between middle part and afterbody, and the shape of head is platypelloid type, and the shape of the shape at middle part, the shape of step and afterbody is all cylindrical, the diameter at middle part is less than the width of head, the width of head equals the diameter of step, and the diameter of afterbody is greater than the diameter of step, and head is provided with the first through hole and the second through hole.
As further improvement of the utility model, described afterbody is provided with a screwed hole.
As further improvement of the utility model, the mid portion at described middle part is provided with a baffle plate, and the both sides of baffle plate form the first groove and the second groove.
As further improvement of the utility model, the diameter of described first through hole is identical with the diameter of the second through hole.
Beneficial effect: compared with prior art, it has following beneficial effect to the utility model:
The contact of the utility model primary cut-out can not loosen in the course of the work, fixed, improves useful life, ensure that the working effect of primary cut-out.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the contact of primary cut-out.
Fig. 2 is the front view of the contact of primary cut-out.
Fig. 3 is the end view of the contact of primary cut-out.
Embodiment
Consult Fig. 1 ~ 3, a contact for primary cut-out, comprises head 10, middle part 20, step 30, afterbody 40, and described head 10, middle part 20, step 30, afterbody 40 are all formed by the manufacture of Z25 material, Z25 material is a kind of carbon structural steels, avoids producing lamellar tearing during welding.Head 10 is one-body molded with middle part 20, step 30 is between middle part 20 and afterbody 40, the shape of head 10 is platypelloid type, the shape of the middle part shape of 20, the shape of step 30 and afterbody 40 is all cylindrical, the diameter at middle part 20 is less than the width of head 10, the width of head 10 equals the diameter of step 30, and the diameter of afterbody 40 is greater than the diameter of step 30, and head 10 is provided with the first through hole 101 and the second through hole 102.
Afterbody 40 is provided with a screwed hole 401, and the retaining elements such as bolt can pass the first through hole 101, second through hole 102, and screw etc. can be threaded with screwed hole 401, such convenience is located and is fixed, fixed, improve useful life, ensure that the working effect of primary cut-out.
As preferably, the mid portion at middle part 20 is provided with a baffle plate 201, and the both sides of baffle plate 201 form the first groove 2011 and the second groove 2012, so conveniently position and engage.
As preferably, the diameter of the first through hole 101 is identical with the diameter of the second through hole 102, fixing so more firm.
In the primary cut-out course of work, first other elements engage with the first groove, the second groove by contact, are then fixed by the first through hole, the second through hole, screwed hole and other elements.
In sum, the contact of the utility model primary cut-out can not loosen in the course of the work, fixed, improves useful life, ensure that the working effect of primary cut-out.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection range of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
