Embodiment

For making the technical solution of the utility model and advantage clearer, by reference to the accompanying drawings the utility model is described in further detail below by embodiment.

General idea of the present utility model is: by tab and supportive body split are arranged, and each tab is carried out independent fixing, make tab adjustable within the specific limits, and can carry out separately installation and maintenance.

Below, in connection with Figure of description specific implementation of the present utility model is elaborated:

In the present embodiment, the bus-bar that provides mainly comprises: supportive body, at least one tab and at least one device for fastening.Wherein supportive body is mainly used in each parts of bus-bar are integrated assembling; In the present embodiment, groove of supportive body, more excellent, can select cross section is U-shaped groove; Because tab and supportive body are the split setting, so must be provided with the breach that at least one is used for placing tab at the supportive body sidewall; Simultaneously, tab is fixed tightly on the supportive body by device for fastening.

Please refer to Fig. 1 and Fig. 4, more excellent, can select this kind supportive body 10 structures, in the present embodiment, except can realizing the removable setting of tab, tab is regulated within the specific limits, at this moment, the set-up mode of supportive body 10 is: be provided with the breach that is used for placing tab of at least one pair of symmetry on supportive body 10 two sides, tab can vertically be placed among two breach of this symmetry.

To please refer to Fig. 2, to settle conveniently in order making, more excellent, tab 20 is chosen as strip; And in order to make tab 20 unlikely landings go out supportive conductors 10, and in certain top/bottom latitude, regulate, can at least one be set at tab 20 sides and move up and down spacing stopper section for pair of tabs, more excellent, as shown in Figure 2, can two projections 201 be set correspondence on the dual-side of tab centre position, the length between these two projections is greater than the opening length of breach on the supportive body, so can play the effect of backstop.

In Fig. 1, on the supportive body, a kind of more excellent set-up mode is: be equidistant setting between the adjacent breach that arranges on its two side.

In the present embodiment, be the corresponding breach that arranges on the supportive body 10 because place the position of tab 20, namely the one side of tab 20 pushes against with device for fastening, and the back side then pushes against with the contact-making surface of its place breach; Perhaps can be convexly equipped with projection in supportive body inside, tab 20 and supportive body 10 are pushed against, tighten up thereby device for fastening is finished.And wherein also have a kind of more excellent set-up mode, please refer to Fig. 1, Fig. 3 and Fig. 4:

In the present embodiment, bus-bar also comprises the conductor 30 that confluxes, the cross section of this conductor 30 that confluxes is L-shaped, it is installed on the described supportive body 10, so the U-shaped open end at supportive body 10 inwardly is provided with at least one pair of relative projection 101,102, accordingly, be provided with the through hole 301 that matches with projection 101 on the side end on the supportive body 10 in the described conductor 30 1 side corners of confluxing, and described supportive body inside is stretched in the another side of the conductor 30 that confluxes, mutually push against with the projection 102 on the end, another side on the described supportive body, thereby tighten up this conductor 30 that confluxes; Accordingly, 20 of tabs can cooperate device for fastening to be pushed against this conductor 30 that confluxes to stretch on that side of supportive body.In the present embodiment, because tab 20 is pushed against on the conductor 30 that confluxes, so corresponding, the breach 103 that is used for placing tab 20 on the supportive body 10 can be set to U-shaped through hole as described in Figure 1.On an end face of the conductor 30 that confluxes, also be provided with the fixing hole 302 for the fixed cable wiring.

In practical operation, easily realize, device for fastening in the present embodiment on the bus-bar can be chosen as screw 401, and accordingly need to be at the supportive body 10 bottoms setting screwed hole 401 suitable with it, screw 401 screws by this screwed hole 104, be crimped on the described tab 20, described tab 20 is fixed tightly on the described supportive body 10; And for tab 20 also can be fixed preferably at correspondence position, more excellent, the setting position of screwed hole 104 arranges corresponding to the position of the symmetric windows 103 of placing tab 20.

And in order to make tightening up of tab 20 more firm and practical, when unclamping screw 401, tab 20 is unlikely to unexpected landing, can an elastic device that match and use with device for fastening be set at bus-bar, more excellent, this elastic device can be for being socketed in the spring on the screw; Also or elastic pressuring plate as shown in Figure 5 50, this elastic pressuring plate is U-shaped, for structure is more firm, but its integrated molding; Accordingly, in supportive body 10 bottoms, the both sides of each screwed hole 104 are provided with a pair of through hole 105 symmetrical centered by screwed hole 104; And the openend two ends 501 of elastic pressuring plate 50 pass with fixing from inside to outside from this through hole 105, and the base plate 502 of elastic pressuring plate 50 then pushes against tab 20, and screw 401 compresses this base plate 502, thereby is fixed to tab 20.And in order to make this elastic device have elasticity, the openings of sizes of elastic pressuring plate 50 is not equal to the length of its base plate, like this when elastic pressuring plate 50 opening two ends 501 are inserted in the through hole 105, elastic pressuring plate 50 produces certain elastic deformation, thereby acquisition elasticity, elastic pressuring plate 50 can independently be pressed on the tab 20, to guarantee reliable crimping and to get loose.

Above content is in conjunction with concrete execution mode further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
