Detailed description of the invention
In order to solve the loaded down with trivial details problem of vacuum arc-extinguishing chamber contact fixing step in prior art, the utility model is carriedSupply a kind of vacuum arc-extinguishing chamber contact, by contact is positioned to rivet welding, thereby contact can once have been weldedConnect, simplified operating procedure, and reduced manufacturing cost. Below in conjunction with accompanying drawing and embodiment, rightThe utility model is further elaborated. Should be appreciated that specific embodiment described herein only usesTo explain the utility model, do not limit the utility model.
The contact riveting method of completing the square that adopts the utility model realizes the fixing of contact, specifically, exactly vacuum is gone outThe mode that the contact of arc chamber assembles by riveted joint, together rivets assembling also by itself and integrated electrode and solder sheetAnd be fixed into as a whole, then with other part composition homogeneous tube, in vacuum drying oven, realize " completely onceEnvelope row " welding procedure. It has abandoned original first parts welding and leak detection completely, then the what is called of homogeneous tube welding" one-step seal-exhaust " technique, all parts, only through a heat treatment process, have not only alleviated " hard significantlyThe deliquescing of state oxygen-free copper " quality problems, and also the uniformity of product improved significantly, and carry significantlyHigh production efficiency and the serviceability of product.
When concrete enforcement, the utility model, aspect the configuration of work die clamper and relevant device, needs stainless steelRiveting blunderbuss and relevant work die clamper.
It should be noted that, existing contact is to be fixedly mounted with technology by contact to realize, assembly processAfter, contact is also in semifixed state, is in completely and adopt contact riveting to join the fixing contact of technologyFixing state, can form the parts that fix, then is assembled into homogeneous tube, directly realizes " completely once envelopeRow " welding procedure. And contact is mounted with technique, is first contact to be assembled on parts, then weldsFixed part, then parts are hunted leak, the parts that do not leak are assembled into homogeneous tube again, finally carry out so-called" one-step seal-exhaust welding " technique. Therefore, adopt vacuum arc-extinguishing chamber contact riveting of the present utility model to join technology,To reduce widely loaded down with trivial details operation, reduce production costs, increase work efficiency. While is due to the anaerobic of hard stateCopper has lacked heat treatment process, keeps mechanical strength more favourable to it, produces the high conformity of product in enormous quantities,Result of the test is very obvious!
When concrete enforcement, the utility model is provided with backstay in the center of two contacts, by described twoIndividual contact carries out rivet welding, and described two contacts and two conducting rod positions are fixed.
, the utility model is realized the one-body molded of contact by contact being positioned to rivet welding.
Wherein, described backstay of the present utility model is cylinder, and those skilled in the art also can certainlyActual needs is set to other shape, as square or rectangular cylinder, etc.
Described conducting rod of the present utility model comprises moving conductive rod 1 and static conductive rod 6, and contact periphery successivelyBe provided with radome 2, shielding cylinder 3 and metallization porcelain shell 4. Described radome 2, described shielding cylinder 3 and described inMetallization porcelain shell 4 is all tightly connected; Described radome 2, described shielding cylinder 3 and described metallization porcelain shell 4Be cylinder.
The utility model also comprises: porcelain shell; Described porcelain valve jacket is contained in shielding cylinder 3 outsides;
The two ends of described porcelain shell be tightly connected respectively moved end cover plate and quiet end casing, described moved end cover plate has logicalHole, the outside of the described moved end cover plate positioning disk that is tightly connected, one end of described fairlead and described positioning disk are closeEnvelope connects, and the other end passes through this through hole.
The inner seal of described moved end cover plate connects one end of bellows; The other end of described bellows connects screenCover cover; Described radome is connected with described moving conductive rod 1 simultaneously; Described bellows-sheathed is contained in described fairleadOutward. Described quiet end casing has through hole, and static conductive rod 6 is through this through hole, and described static conductive rod 6 withThe edge seal of this through hole connects.
