Embodiment

The short module of bus bar of the present utility model can be installed on DC micro circuit breaker or DC switch, hereinafter, describe with reference to the accompanying drawings the short module of bus bar of the present utility model and with the annexation of miniature circuit breaker and switch.

At the embodiment of this record, being specific embodiment of the present utility model, for design of the present utility model is described, is all explanatory and exemplary, should not be construed as the restriction to the utility model execution mode and the utility model scope.Except the embodiment of this record, those skilled in the art can also adopt apparent other technical scheme based on the application's claims and the disclosed content of specification, and these technical schemes comprise the technical scheme of making any apparent substitutions and modifications adopting the embodiment in this record.

The accompanying drawing of this specification is schematic diagram, and aid illustration design of the present utility model schematically shows shape and the correlation thereof of each several part.Identical reference marker is for part like representation class.

Referring to Fig. 2, it shows the stereogram of the miniature circuit breaker with the short module of bus bar of the present utility model.As shown in the figure, the terminal part that the short module 1 of bus bar of the present utility model is arranged on miniature circuit breaker 2 is as pre-wiring part.In the utility model, adopting " short module " this term is for bus bar common in prior art.The size of common bus bar of the prior art is more much longer than module of the present utility model, thereby adopts " short module " this term in the utility model.

Further, referring to Fig. 3 and 4, wherein, Fig. 3 illustrates the stereogram that the short module 1 of bus bar of the present utility model and miniature circuit breaker 2 separate, and Fig. 4 illustrates the three-dimensional exploded view that the short module 1 of bus bar of the present utility model and miniature circuit breaker 2 separate.As shown in Figure 3, bus bar 12 and 12 ' inserts respectively the binding post of miniature circuit breaker 2, then is anchored on binding post via the short module of bus bar.Referring to Fig. 4, the short module 1 of bus bar is schematically decomposed into module matrix 11 and bus bar 12 and 12 ' again.

As shown in Figure 4, the short module 1 of bus bar comprises module matrix 11 and bus bar 12 and 12 ', and module matrix 11 is made by the macromolecular material that dispels the heat and insulate, for example, be heat radiation plastics, and bus bar 12 and 12 ' is preferably copper bar.In bus bar 12 and 12 ' merge module matrix 11, form as one with module matrix 11.Two bus bars 12 and 12 ' comprise respectively two binding posts.The manufacture of bus bar 12 and 12 ' merge module matrix 11 is preferably injection moulding, makes bus bar 12 and 12 ' in injection molding, imbed module matrix and be combined as a whole with module matrix.In addition, bus bar 12 and 12 ' and module matrix 11 also can shape respectively, then bus bar 12 and 12 ' be sticked in to module matrix 11 and form as one.The utility model wishes that the short module 1 of bus bar can dispel the heat as early as possible, therefore, the manufacture being combined as a whole with module matrix with making bus bar 12 imbed module matrix with 12 ' in injection molding is compared, and bus bar 12 and 12 ' is sticked in to module matrix 11 and the thermal diffusivity of the manufacture that forms as one is less better.

In example prior art as shown in Figure 1, only adopt two wires of tape insulation rubber to carry out pre-wiring, thereby bother manyly in the process of not only installing, and because the heat dispersion of wire is poor, and the length of wire is very limited, thereby temperature rise is larger when the work of wire, this not only makes product have potential safety hazard in when work, and along with the use of product, the insulation property of wire are variation gradually.

Compared with prior art, the short module 1 of the utility model bus bar has adopted bus bar 12 and 12 ' and the modularization fixed structure that forms as one of module matrix 11, bus bar 12 and 12 ' self caloric value are just lower, and because module matrix 11 adopts the macromolecular material manufacture of not only dispelling the heat but also insulating of heat radiation plastics and so on, so the heat dispersion of the short module 1 of bus bar is fine, potential safety hazard while so both having eliminated work, has guaranteed again insulating properties.

As shown in Figure 3, when the short module 1 of bus bar is arranged on the terminal part of miniature circuit breaker 2, that the form sealing is inserted on the terminal part of miniature circuit breaker 2, thereby degree of protection at least can reach national standard (GB 4208-2008/IEC60529:2001) the defined IP20 of the shell protection grade of electric equipment, and there is not Insulation Problems.

Said structure from the short module 1 of the utility model bus bar, because the short module 1 of bus bar has adopted the modularization fixed structure of one, so the mode of connection of the short module 1 median generatrix row's 12 and 12 ' of bus bar terminal is fixed, and the short module 1 of bus bar can have different model corresponding to different terminal connections modes.Like this, miniature circuit breaker 2 or DC switch can select to have the short module 1 of bus bar of the different modes of connection as required, after the mode of connection of terminal of having selected the short module 1 of bus bar, only the terminal of the short module 1 of bus bar need be inserted to the binding post of miniature circuit breaker 2 or DC switch, thereby the operation when miniature circuit breaker 2 or DC switch need expanded application simplifies greatly, or even layman also can short module 1 operate according to selected bus bar.

Above the short module of bus bar of the present utility model and advantage of the present utility model are illustrated.As mentioned above, for the specific features of the short module of bus bar of the present utility model, as the effect of feature that shape, size and position can above-mentioned disclosures, carry out specific design, these designs are all that those skilled in the art can realize.And, each technical characterictic of above-mentioned disclosure that be not limited to disclose with combination further feature, those skilled in the art also can carry out other combination between each technical characterictic according to the object of invention, to realize the object of the utility model, are as the criterion.
