Background technology
In order to meet the needs of the high-current low-voltage transmission line in industry, civil engineering construction, the bus duct mains system is all adopted in the power distribution design, continuing to increase along with the electric line capacity in recent years, the bus duct mains system is widely applied in engineering, the structural design of bus duct product is also from the air-insulated type to the dense insulation type, from the outer cover of steel plate to the aluminum alloy casing, realization progressively update; Bus groove case of the present utility model is applicable dense insulation type bus duct mainly, in prior art, dense insulation type bus duct generally has upper cover plate, lower cover and two side plate formations and forms the spatial accommodation of putting bus bar, the gross thickness correspondence of the bus bar that forms due to bus bar or bus bar close-packed arrays unique bus duct, therefore, in the situation that often need to adjust bus bar, also often need to change more applicable concentration bus duct, make the applicability of bus duct more single, also make staff's installation procedure loaded down with trivial details many.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of housing of concentration bus duct simple in structure, applied widely is provided.
for achieving the above object, the utility model adopts compact bus groove case, comprise the first main casing and the second main casing, the wherein opening-like state of side of described the first main casing and the second main casing, and the corresponding setting of described opening, and then be formed for putting the cavity that holds of bus bar between the first main casing and the second main casing, described the first main casing has the first longitudinal side wall and respectively from first crossbeam and the second cross beam of the horizontal expansion of two ends up and down of described the first longitudinal side wall, offer the first lateral insert on the side end face of described first crossbeam end, this first lateral insert has several anti-skidding sawtooth on corresponding two sides in a longitudinal direction, the lozenges that described anti-skidding sawtooth has is towards opening one side of the first lateral insert, offer the second lateral insert on the side end face of described second cross beam end, described the second main casing has the second longitudinal side wall and respectively from the 3rd crossbeam and the 4th crossbeam of the horizontal expansion of two ends up and down of described the second longitudinal side wall, laterally be extended with guide plate on the side end face of described the 4th beam-ends, this guide plate forms horizontal sliding with described the second lateral insert and coordinates, laterally extend and be provided with horizontal plate on the side end face of described the 3rd beam-ends, the centre position of this horizontal plate offers fluting, and described horizontal plate is by forming upper horizontal plate and lower horizontal plate cutting apart of this fluting, has respectively at least one anticreep sawtooth on the upper surface of described horizontal plate and the lower surface of lower horizontal plate, described the first main casing and the second main casing be the location of the laterally steering in the second lateral insert by guide plate, and makes the anti-skidding sawtooth in described anticreep sawtooth and described the first lateral insert form horizontal clamping.
Concrete, be respectively arranged with several heat sink strips on the lateral surface of described the first longitudinal side wall and the second longitudinal side wall.
the utility model is by the above-mentioned improvement to prior art, reached the beneficial effect of following three aspects:: 1, offer the second lateral insert on second cross beam due to the first main casing, and be provided with on the 4th crossbeam of the second main casing with described the second lateral insert and form the guide plate that horizontal sliding coordinates, therefore, when the second lateral insert is advanced in the guide plate slippage, the first lateral insert of first crossbeam corresponding with the horizontal plate position in a lateral direction on the 3rd crossbeam and by the form of interting make in the first lateral insert anti-skidding sawtooth respectively with upper horizontal plate and lower horizontal plate on the anticreep sawtooth form clamping, therefore, apparent, this bus groove case can be regulated in the stroke distances scope of guide plate and the second lateral insert, the expansion that the scope of application is obvious, and because fluting has been offered in the centre position at horizontal plate, make horizontal plate and lower horizontal plate in the two-sided clamping of realization and the second lateral insert, effectively guaranteed the reliability of this clamping effect, 2, because the shell structure with prior art median generatrix groove is improved to two main shell structures that connect by the form that upper cover plate, lower cover and two of left and right side plate form, and then avoided greatly affecting the dissatisfactory defect of bus duct radiating effect because of the existence of the fit-up gap of upper cover plate and lower cover and side plate, therefore, the apparent area of dissipation that increases main casing, improved radiating effect, 3, because only having two main casing docking, bus groove case of the present utility model forms, except not having the fit-up gap between cover plate and side plate, also obviously cancellation the use of upper cover plate and lower cover, and reduced the cost payout of upper cover plate and lower cover, not only simple in structure, and effectively reduce production cost.
