Embodiment
The auxiliary connecting plate fixed structure of circuit breaker the utility model embodiment provided below in conjunction with accompanying drawing is elaborated.
As shown in Fig. 1,2 and 4, described circuit breaker is assisted the connecting plate fixed structure, comprises pedestal 1, auxiliary connecting plate 2 and stopper 3, wherein,
As shown in Figure 2, described pedestal 1 has the first polarity chamber 11 of being separated and communicating and for the second polarity chamber 12 of connecting plate 4 is installed;
Described stopper 3 is removably mounted in described the first polarity chamber 11, between described stopper 3 and described the first polarity chamber 11, has the container cavity 5 for holding described auxiliary connecting plate 2.
Pass through said structure, because auxiliary connecting plate 2 is not arranged in the polarity chamber of the same side of the same polarity of circuit breaker with connecting plate 4, therefore, after circuit breaker needs plate during wiring, the operator be can be beneficial to and stopper 3 and auxiliary connecting plate 2, the simple and effective binding post of packing into dismantled; Simultaneously, after plate, the binding post of wiring will directly contact with silver-plated connecting plate 4, effectively guarantees that product wiring place temperature rise is unlikely too high.
Below describe two kinds of forms of container cavity 5 in detail; but it will be appreciated that; the form of container cavity 5 is not limited to this; the change that those skilled in the art can be equal to it, replacement or modification; as long as it can realize assisting connecting plate and connecting plate not to be arranged on the same position place; and can realize the function that binding post is fixing, just fall in the protection range of claim of the present utility model, particularly:
Mode one
In this mode one, as shown in Figure 2, have respectively on described the first aspectant two side 111, polarity chamber 11 along its short transverse and extend, but do not extend to the projection 113 of the end face 112 in described the first polarity chamber 11; Described protruding 113 form described container cavity 5 with described end face 112; Accordingly, as shown in Figure 3, on the side 31 coordinated with described two side 111 of described stopper 3, have and described protruding 113 grooves that coordinate 32.
Like this, at first auxiliary connecting plate 2 is inserted in container cavity 5, and its end face with projection 113 is contacted, and then by stopper 3, the cooperation along groove 32 and projection 113 is inserted in the first polarity chamber 111, thereby will assist connecting plate 2 fixed installations.
Certainly, the mutual correspondence that the position of the projection 113 on described the first aspectant two side 111, polarity chamber 11 can be as shown in Figure 2, can be not corresponding and the setting of staggering yet.Accordingly, groove 32 need to coordinate with projection 113.
Further, as shown in Figure 3, be formed with gripping mechanism on described groove 32 and/or described protruding 113, for example be positioned at the inclination protuberance 6 of groove 32 bottoms, with at described groove 32 when described protruding 113 coordinate, the diapire of projection 113 will be clamped on inclination protuberance 6, thereby stopper 3 and pedestal 1 can be tightened, and prevent that stopper 3 from coming off.
In mode one, projection 113 this structure has been avoided the depanning mode of side core-pulling in compression mod or mould of plastics, when greatly reducing die cost, can effectively realize its functional requirement.
Mode two
This mode two is just contrary with mode one, have respectively on described the first 11 two side, polarity chamber 111 along its short transverse and extend, but the groove that does not extend to the end face 112 in described the first polarity chamber 11 (does not show in figure, but those skilled in the art can understand according to this description and accompanying drawing), accordingly, having the excrescence coordinated with described groove on the side 31 coordinated with described two side 111 of described stopper 3 (does not show in figure, but its shape is similar with projection 113), the thickness of this excrescence is greater than the degree of depth of described groove, with when both coordinate, be that excrescence is while being engaged in groove, described excrescence can and make excrescence form described container cavity 5 towards end face and the described end face 112 of described end face 112 higher than described groove.
Like this, at first auxiliary connecting plate 2 is inserted in container cavity 5, make the end contact of the part exceeded from described groove of itself and described excrescence, then by stopper 3, the cooperation along described groove and described excrescence is inserted in the first polarity chamber 111, thereby will assist connecting plate 2 fixed installations.
Certainly, the position of the projection as shown in Figure 2 113 that the position of the described groove on described the first aspectant two side 111, polarity chamber 11 can be described with mode one is mutually corresponding, also can be not corresponding and the setting of staggering.Accordingly, described excrescence need to coordinate with described groove.
Further, on described groove and/or described excrescence, be formed with gripping mechanism, can tighten with stopper when described groove coordinates with described excrescence 3 and pedestal 1, prevent that stopper 3 is left out.
At this, it should be noted that, the gripping mechanism in mode two can be identical with the gripping mechanism in mode one, at this, no longer illustrates.
In addition, as shown in Figures 3 and 4, the lateral wall of described stopper 3 has extension 33, described extension 33 is in described stopper 3 is arranged on described the first polarity chamber 11 time, can seal the opening of described container cavity 5, thereby form complete enclosure space the auxiliary connecting plate 2 of parcel tightly, make auxiliary connecting plate 2 not be exposed to the external world, and prevent that its landing from falling.
Therefore, in two kinds of structures of mode one and mode two, pedestal 1, auxiliary connecting plate 2 and stopper 3 cooperatively interact, and are the external wiring way of circuit breaker, and effective coupling mechanism force is provided.Simultaneously, during wiring, can be beneficial to the operator and dismantle stopper 3 and auxiliary connecting plate 2, the simple and effective binding post of packing into after circuit breaker need to be used plate; Simultaneously, after plate, the binding post of wiring will directly contact with silver-plated connecting plate 4, effectively guarantees that product wiring place temperature rise is unlikely too high.
In addition, the height of described container cavity 5 is identical with the thickness of described auxiliary connecting plate 2, like this, after auxiliary connecting plate 2 is installed, can make its upper surface contact with described end face 112, the end contact of lower surface and described protruding 113 end face or described excrescence, the installation that is more conducive to auxiliary connecting plate 2 is fixed.
In addition, as shown in Figure 2, there is respectively the guiding projection 122 of the described connecting plate 4 of guiding on the aspectant side 121 in described the second polarity chamber 12, thereby can guide location to it when connecting plate 4 is installed, be convenient to its assembling and align.
Obviously, above-described embodiment is only for example clearly is described, is not the restriction to execution mode.Concerning those of ordinary skill in the field, also can make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And among the protection range that the apparent variation of being extended out thus or change are still created in the utility model.
