Detailed description of the invention

For technical problem, technical scheme and beneficial effect that the utility model is solved clearer,Below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that hereinDescribed specific embodiment is only in order to explain the utility model, and is not used in restriction the utility model.

In description of the present utility model, it will be appreciated that, term " length ", " width ", " on ", D score,The fingers such as 'fornt', 'back', " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", " outward "The orientation showing or position relationship, for based on orientation shown in the drawings or position relationship, are only for convenience of description originallyUtility model and simplified characterization, instead of device or the element of instruction or hint indication must have specific sidePosition, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model. In this realityWith in novel description, except as otherwise noted, the implication of " multiple " is two or more.

In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, artLanguage " installation ", " setting ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and also canBe to removably connect, or connect integratedly; Can be to be directly connected, also can pass through the indirect phase of intermediaryConnect. For the ordinary skill in the art, can concrete condition understand above-mentioned term in this practicality newlyConcrete meaning in type.

Fig. 1 and Fig. 2 show the structure of the bus duct that the utility model preferred embodiment provides.

Concrete, this bus duct comprises the framework as main body. This framework is cuboid column, framework substantiallyEdge is " ∏ " type perpendicular to the cross section of its length direction.

This framework specifically comprises horizontally disposed top board 7 and from the both sides of top board 7 widths to downward-extension3, two parallel being oppositely arranged of side plate 3 of side plate. On the surface of each side plate 3, all have for fixed insulationThe hook of plate 2. Lay respectively at two hooks on side plate 3 between two side plates 3, i.e. this hookShape body is positioned at framework.

On the top board 7 at framework top, be fixed with ground wire connecting plate 4.

Bottom as two side plates 3 of frame side wall is all fixed with bus rail 5. Two bus rails 5 are mutualBe arranged in parallel. And between two bus rails 5, there is the gap that can insert for the plugboard 9 of jack box 8.For example, for the limbs (finger) of avoiding workmen insert framework inside, under preferable case, two bus rails 5Between centre distance be 10-15mm, more preferably 12-14.

With existing similar, this bus duct has four guide rails 1.

Meanwhile, this bus duct also comprises four insulation boards 2 for fixing four guide rails 1. Concrete as Fig. 3 instituteShow, this insulation board 2 comprises body 21 and extended two fixed claws 22 from body 21.

As shown in Figures 2 and 3, guide rail 1 is firmly connected between two fixed claws 22. Guide rail 1 passes throughAbove-mentioned insulation board 2 is fixed in framework. For realizing the good insulation between guide rail 1 and framework, insulation board 2Adopt insulation material to make, under preferable case, insulation board 2 is glass mat.

Referring to Fig. 1 and Fig. 3, the insulator that is fixed with guide rail 1 is fixed on the side plate 3 of framework, insulation positionIn framework.

In framework, four rectangular distributions of insulator. The fixing guide rail 1 length side along framework on insulatorTo extension.

Meanwhile, in framework, between two insulators of sustained height, there is gap, so that jack box 8Plugboard 9 insert.

In above-mentioned bus duct, guide rail 1 is rectangular distribution in framework, compact conformation. Meanwhile, at the bottom of bus ductPortion has the gap that can insert for the plugboard 9 of jack box 8, when jack box 8 is pegged graft, flexible to operation.

Meanwhile, this bus duct also comprises end cap 6. Conventionally guide rail 1 extends along the length direction of framework, guide rail 1Two ends be all positioned at outside framework, in the end of bus duct, end cap 6 is set, by the cooperation of end cap 6 and framework,Guide rail 1 is encapsulated, avoid exposing of guide rail 1.

As shown in Figure 3, when jack box 8 is pegged graft, plugboard 9 from two bus rails 5 of bus duct bottom itBetween upwards insert, now, plugboard 9 is between four guide rails 1, plugboard 9 both sides all have respectivelyBe positioned at two guide rails 1 on differing heights, operation jack box 8 can conveniently be realized between jack box 8 and guide rail 1Conducting.

Meanwhile, the in the situation that of having ground connection pawl 10 at jack box 8 tops, jack box 8 upwards inserts bus ductTime, ground connection pawl 10 can contact conducting with bus rail 5, at jack box 8 and guide rail 1 not conducting in the situation that,First realize the ground connection between bus rail 5 and jack box 8, greatly improved the security using.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,All any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all shouldWithin being included in protection domain of the present utility model.
