Description
Technical field:
The present invention relates to a kind of dynamic-contact braided-line cold press of circuit breaker, belong to the electrical equipment manufacturing
Technical field.
Background technology:
The moving contact of breaker pigtail lines is a very important conductive pieces that connects contact and contact busbar in the circuit breaker.At present, welding procedure is all adopted in being connected between moving contact of breaker system busbar and the pigtail lines both at home and abroad usually.This welding procedure causes the branch of circuit breaker, fashionable resistance to increase because welding current is big, conduction time is long, is easy to cause the lead hardening of pigtail lines root, causes circuit breaker to be difficult to branch, to close, thereby the branch, the cooperation that have lost circuit breaker are used; In addition, because in the welding process, the electric current that needs is big, the time is longer, therefore, this welding procedure is the power consumption "big tiger" in the circuit breaker production process always, also is one of high major reason of circuit breaker production cost.For addressing this problem, some external industrially developed country have adopted laser welding moving contact of breaker pigtail lines technology, but its energy consumption issues also never is resolved, and a laser welding apparatus needs more than 100 ten thousand dollars, the height of its production cost, general manufacturing enterprise can't use at all.
Summary of the invention:
The present invention is intended to solve the problem of above-mentioned existence, and a kind of dynamic-contact braided-line cold press of circuit breaker is provided.
Dynamic-contact braided-line cold press of circuit breaker of the present invention is divided into: the parts preliminary treatment of moving contact of breaker pigtail lines and cold extrusion two parts, and the preliminary treatment of moving contact of breaker pigtail lines parts comprises: contact is thrown removed cupric oxide; The processing at contact end stationary fit position; Cold extrusion comprises: the special fixture of design contact pigtail lines; With special fixture pressure being adopted at contact end stationary fit position is that 25～40 tons forcing press vertically is pressed in the busbar groove, from left to right, the sub-line contact of distinguishing of compression moulding is pressed into piecemeal, then, adopt special fixture, suppress from the top down, contact stationary fit position and busbar are tightly squeezed close, seamless; Thereby finished seamless tight connection the between moving contact of breaker system and the pigtail lines.
Dynamic-contact braided-line cold press of circuit breaker one of the present invention need not be a large amount of fund, equipment investment; Two need not consume a large amount of electric energy, and production cost is low; Three production technologies are simple, production efficiency height, reliable product quality, long service life.
In addition, the not hardening of pigtail lines root of adopting dynamic-contact braided-line cold press of circuit breaker of the present invention to produce, contact resistance is little, thermally-stabilised good, pigtail lines and busbar loop resistance have only 9～17 micro-ohms after tested, being better than adopting the laser welding loop resistance abroad is 22 micro-ohm technical performance indexs, has reached the requirement of every technical performance index of circuit breaker defined fully, and can satisfy the needs of mass industrialized production.

Embodiment:
Be elaborated below in conjunction with the execution mode of accompanying drawing to dynamic-contact braided-line cold press of circuit breaker of the present invention:
Dynamic-contact braided-line cold press of circuit breaker is divided into the parts preliminary treatment of moving contact of breaker pigtail lines and cold extrusion two parts; Wherein, the pretreatment portion division technique is:
To scheme (1) contact A end place and throw except that cupric oxide with the fabric disc machine on four sides, and the four sides at contact A end stationary fit position is smooth, no convex-concave, size conforms stationary fit requirement;
Cold-extrusion technology:
A, with the special fixture 2 of designed contact pigtail lines, its width is than figure (2) busbar groove each wide 2mm of both sides; Adopt pressure be 25～40 tons forcing press by contact end stationary fit position vertically being pressed in the busbar groove with special fixture, from left to right, contact is pressed into piecemeal, make that contact stationary fit position and busbar are tightly crowded to be closed;
B, with the special fixture 5 of designed contact pigtail lines, its width is than figure (2) busbar groove each narrow 1mm of both sides, and adopting pressure then is 25～40 tons forcing press, from the top down, contact is pressed into piecemeal, and making becomes gapless connector between contact stationary fit position and the busbar.
The moving contact of breaker pigtail lines that adopts above-mentioned cold-extrusion technology production is delivered to product quality inspection unit to be detected.Show after tested: this pigtail lines and busbar loop resistance have only 9～17 micro-ohms, and being better than adopting the laser welding loop resistance abroad is 22 micro-ohm technical performance indexs, has reached the requirement of every technical performance index of circuit breaker defined fully.
