Abstract
The invention relates to a rapid and safe bus connecting assembly which comprises two buses connected with each other in a lap joint mode. A U-shaped clamp is connected with the lap joint position of the two buses in a sleeved mode. One or more pressing screws perpendicular to the lap joint face of the buses are connected to one side face of the U-shaped clamp in a rotating mode. The head portion of the pressing screw is inserted into the U-shaped clamp in the state that the head portion of the pressing screw abuts against the two buses and the inner wall of the U-shaped clamp. The U-shaped clamp is connected outside the lap joint portion of the two buses in the sleeved mode, the pressing screw perpendicular to the plane of the buses is then used for extruding the buses to be locked into the U-shaped clamp, and the bus connecting assembly is reliable in connecting mode and easy to detach; an insulating pressing accessory is arranged between the head portion of the pressing screw and the contact face of the buses, electricity leakage is avoided, the pressing screw is prevented from pressing and damaging the buses, and meanwhile the locking force of the pressing screw is evenly distributed on the contact plane of the buses; the U-shaped clamp is an insulator, and therefore the bus connecting assembly is safe and reliable.
Description
Technical field
The present invention relates to a kind of coupling assembling, be specifically related to a kind of bus coupling assembling fast and safely.
Background technology
At present, the double-row horizontal bus of power switchgear normally adopts the coupling assembling being made up of nut, bolt, baffle plate to be connected with double vertical bus, pick out a single bus from vertical bus, after single bus intersects with horizontal bus, on single bus, punch, bolt is connected with nut with the baffle plate leaning against on bus through hole, and bus is fixedly connected with.The deficiency of this connected mode is: mode of (1) on-the-spot punching bothers in the time connecting, and connecting time error, to cause more greatly connecting workload large; (2) punching has injury to busbar surface, and busbar easily deforms, and faying surface laminating degree is bad, and the edge in hole easily gathers the electric current electric current that tapers off to a point, guiding discharge or burn out.The disclosed cross bus coupling assembling of patent 201120068202, its technical characterstic is: comprise bolt, nut, spacing block and baffle plate, the top of spacing block is respectively equipped with baffle plate with transferring, two groups of bus difference cross-distribution are in the cavity of spacing block and overhead gage and lower baffle plate stroke, fix with bolt cross-under overhead gage, spacing block and lower baffle plate again, the defect of this technical scheme is to limit and cross-coupled occasion, can not be used for parallel connected occasion, and this coupling assembling does not possess insulation function, has potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of bus connecting piece fast and safely.
The technical scheme that the present invention takes is:
A kind of bus coupling assembling fast and safely, comprise two buses of mutual overlap joint, described two busbar shiplap joint places are socketed with U-shaped folder, on the side of described U-shaped folder, be connected with an above clamping screw perpendicular to busbar shiplap joint face, described clamping screw head stretches in U-shaped folder and is two buses and U-shaped folder inwall are pushed against to state.
Further, between described clamping screw head and bus, be provided with holddown attachment member, described holddown attachment member is insulator.
Again further, described U-shaped folder is insulator.
Take after above technical scheme, beneficial effect of the present invention is: the outside in the lap-joint of two buses is socketed U-shaped folder, then with the clamping screw perpendicular to bus plane by bus extruding and U-shaped folder internal locking, connected mode is reliable and quick detachable; Between clamping screw head and bus contact-making surface, be provided with insulation holddown attachment member, not only prevent electric leakage but also prevent that hold-down bolt from weighing bus wounded, the coupling mechanism force of hold-down bolt is uniformly distributed in to the contact plane of bus simultaneously; And U-shaped folder is insulator, safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: U-shaped folder 1, the first bus 2, the second buses 3, holddown attachment member 4, clamping screw 5.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described:
As shown in the figure, a kind of bus coupling assembling fast and safely comprises U-shaped folder 1, the first bus 2, the second bus 3, holddown attachment member 4 and clamping screw 5.Described the first bus 2 and the mutual horizontal or vertical overlap joint of the second bus 3, the outside of described lap-joint is socketed with the U-shaped folder 1 of insulation, described clamping screw 5 is rotatably connected in a side of U-shaped folder 1 and stretches in U-shaped folder 1, the axis of clamping screw 5 is vertical with busbar shiplap joint face, and the first bus 2 and the second bus 3 are pushed against the inwall that is locked in U-shaped folder 1 by the head of described clamping screw 5; Between the head of described clamping screw 5 and bus, be provided with the holddown attachment member 4 of insulation.
Claims (3)
1. a bus coupling assembling fast and safely, comprise two buses of mutual overlap joint, it is characterized in that, described two busbar shiplap joint places are socketed with U-shaped folder, on the side of described U-shaped folder, be connected with an above clamping screw perpendicular to busbar shiplap joint face, described clamping screw head stretches in U-shaped folder and is two buses and U-shaped folder inwall are pushed against to state.
2. a kind of bus coupling assembling fast and safely according to claim 1, is characterized in that, between described clamping screw head and bus, be provided with holddown attachment member, described holddown attachment member is insulator.
