Abstract
The invention discloses a breaker busbar. The breaker busbar comprises a connecting plate, wherein a plurality of connecting holes are formed in the connecting plate, at least two step parts are formed on the bottom surface of one end part of the connecting plate, at least two step parts are also formed on the end surface of the end part of the connecting plate correspondingly, a copper flexible wire is connected to the step surface of each step part, and the copper flexible wire connected to the upper step surface is longer than the copper flexible wire connected to the lower step surface. The breaker busbar has the advantages that a step composed of at least two step parts is formed at one end part of the breaker busbar, more copper flexible wires can be welded without changing width of a busbar by adopting a multi-layer welding connecting way, the copper flexible wires are welded in parallel at intervals, so that workers can operate conveniently; a frictional force between the copper flexible wires is small and the copper flexible wires can be hardly damaged, and a milling and welding positioning slot is not formed in the busbar and can be directly drawn by a mould, so that the processing cost is reduced.
Description
Technical field
The present invention relates to a kind of circuit breaker busbar, relate in particular to a kind of busbar for connecting breaker moving contact.
Background technology
Refer to shown in Fig. 1, Fig. 1 is the structural representation of traditional circuit breaker busbar, in traditional HTQII-3200, the busbar of 2000A comprises connecting plate 10, on described connecting plate 10, offer several connecting holes 11, and both sides, an end correspondence of described connecting plate offers 8 groups of location notchs 12 for soldering copper flexible cord, after welding, copper flexible cord has been booked the width of 80 ㎜ connecting plates 10 substantially.But width 80 ㎜ of 3150A busbar but need the welding of 10 groups of copper flexible cords utilize this structure to weld and be certain to exceed 80 ㎜ width, and copper flexible cord is too crowded when welding, causes workman to operate between inconvenience and copper flexible cord frictional force fragile greatly.
Summary of the invention
The object of the present invention is to provide a kind of circuit breaker busbar, it has the many features with reducing processing cost of soldering copper flexible cord radical, to solve the problems referred to above that in prior art, circuit breaker busbar exists.
For reaching this object, the present invention by the following technical solutions:
A kind of circuit breaker busbar, it comprises connecting plate, on described connecting plate, offer several connecting holes, wherein, on the bottom surface of described connecting plate one end, be provided with at least two stage portion, on end face corresponding to this end of described connecting plate, be also provided with at least two stage portion, be connected with copper flexible cord on the step surface of described stage portion, the length that is connected in the copper flexible cord on the step surface of upper strata stage portion is greater than the length of copper flexible cord on the step surface that is connected in lower floor's stage portion.
Especially, on the bottom surface of described connecting plate one end, be provided with upper and lower two stage portion, on the end face corresponding to this end of described connecting plate, be also provided with upper and lower two stage portion.
Especially, described copper flexible cord is connected on corresponding step surface by Resistance Welding.
Especially, described in, top bar portion and the width of portion and highly identical of getting out of a predicament or an embarrassing situation.
Especially, described copper flexible cord parallel interval is fixedly welded on corresponding step surface.
Especially, on the step surface of described upper strata stage portion, on the pad of copper flexible cord and the step surface of described lower floor stage portion, the pad of copper flexible cord is alternately arranged.
Beneficial effect of the present invention is, compared with prior art an end of described circuit breaker busbar adopts the stepped-style being made up of at least two stage portion, the mode being welded to connect by multilayer, has realized under the constant prerequisite of busbar width, can weld the copper flexible cord of more, copper flexible cord parallel interval welding simultaneously, be convenient to workman's operation, the frictional force between copper flexible cord is little not fragile, and busbar has also been removed milling welding location notch from, directly can be drawn out by mould, reduce processing cost.

Embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Refer to shown in Fig. 2 and Fig. 3, in the present embodiment, taking the busbar of 3150A in HTQII-3200 as example, its width is 80 ㎜, need to weld the copper flexible cord of 10 groups 25 squares, connecting plate 20 is drawn together in a kind of circuit breaker bus package, on described connecting plate 20, offer several connecting holes 21, on the bottom surface of described connecting plate 20 1 ends, be provided with the portion of topping bar 22 and the portion 23 of getting out of a predicament or an embarrassing situation, on end face corresponding to this end of described connecting plate 20, be also provided with the portion of topping bar 22 and the portion 23 of getting out of a predicament or an embarrassing situation, described in top bar portion 22 and the width of portion 23 and highly identical of getting out of a predicament or an embarrassing situation.On the portion of topping bar 22 of the bottom surface of described connecting plate 20 and end face and the step surface of the portion 23 of getting out of a predicament or an embarrassing situation, equal parallel interval is by the copper flexible cord 24 of 5 25 squares of electric resistance weldings.
The length that is welded in the copper flexible cord 24 on the step surface of the portion of topping bar 22 is greater than the length of copper flexible cord 24 on the step surface that is welded in the portion of getting out of a predicament or an embarrassing situation 23, described in top bar portion 22 step surface copper flexible cord pad with described in the pad of copper flexible cord on the step surface of portion 23 of getting out of a predicament or an embarrassing situation alternately arrange.
The other end of described copper flexible cord 24 connects moving contact 25.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
