Abstract
The utility model discloses a circuit breaker busbar. The circuit breaker busbar comprises a connecting plate; a plurality of connecting holes are formed in the connecting plate; the bottom surface of an end portion of the connecting plate is provided with at least two step portions; an end surface corresponding to the end portion of the connecting plate is also provided with at least two step portions; the step surfaces of the step portions are connected with soft copper wires; and the length of soft copper wires connected onto upper-layer step surfaces is larger than the length of soft copper wires connected onto lower-layer step surfaces. One end portion of the circuit breaker busbar is of a stepped structure composed of the at least two step portions, and therefore, more soft copper wires can be welded through a multi-layer welding connection mode under the premise that the width of the busbar is not changed; the soft copper wires are parallelly welded at intervals, and therefore, operation of workers can be facilitated, and frictions between the soft copper wires are small, so that the soft copper wires do not tend to be damaged; and positioning grooves are not needed to be milled and welded on the busbar, and the busbar can be directly manufactured by a mould, and processing cost can be reduced.
Description
Technical field
The utility model relates to a kind of circuit breaker busbar, relates 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.
Utility model content
The purpose of this utility model is to provide a kind of circuit breaker busbar, and 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 utility model 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.
The beneficial effects of the utility model are, 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.
Brief description of the drawings
Fig. 1 is the structural representation of traditional circuit breaker busbar;
Fig. 2 is the perspective view of the circuit breaker busbar that provides of the utility model embodiment 1;

Embodiment
Further illustrate the technical solution of the utility model 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 utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
