Description
Technical field
The present invention relates to bus tie, be specifically related to the four-way bus tie connecting for straight edge line in power distribution cabinet.
Background technology
Busbar arrangement complicated in power distribution cabinet usually needs to take larger space, in order to guarantee bus marshalling in power distribution cabinet, institute takes up space little, for the bus tie that is connected between power distribution cabinet and bus except realizing being connected between bus and power distribution cabinet, also need to guarantee the neat layout of bus on power distribution cabinet so that power distribution cabinet can miniaturization, standardization.The disclosed casing shoe of Chinese patent literature CN201113244Y, described casing shoe is comprised of the first taper bushing, the second taper bushing, left sleeve pipe and right sleeve pipe.Described the first taper bushing and described the second taper bushing are point-blank, the center line of described left sleeve pipe and described right sleeve pipe is in the plane vertical with the center line of described the second taper bushing with described the first taper bushing, the angle of described left sleeve pipe and described right sleeve pipe center line is 70-110 °, and described the first taper bushing, the second taper bushing, left sleeve pipe and right sleeve pipe communicate with each other.During use, two curved buses penetrate connection from left and right sleeve pipe respectively, and the second taper bushing coordinates with the cone bucket on insulation burrel, and the first taper bushing coordinates with shutoff after insulation.Chinese patent literature CN101383489B is the actual use of this kind of casing shoe, this patent documentation discloses a kind of special-shaped bus and aligning method thereof, it comprises insulating barrier, conductive cores and connector, connector is at the two ends of conductive cores, and be integrated with conductive cores, the insulating barrier of the outer wrap of conductive cores is made by silicon rubber, conductive cores is circular arc, the connector at conductive cores two ends is at a distance of 300-600mm, distance between the connector line at conductive cores maximum camber and conductive cores two ends is 100-200mm, first row special-shaped bus is arranged in a side of several binding posts, second row special-shaped bus is arranged in the opposite side of several binding posts, straight edge line is arranged in below or the top of first row special-shaped bus and second row special-shaped bus, the arrangement of this special-shaped bus is divided into two-layer up and down, this kind of arrangement mode is by the radian of special-shaped bus, can make the binding post of solid insulation complete enclosed switch isolation cover and casing shoe junction point-blank, being convenient to except bus other parts Standardizations and minimizing takes up room, can make whole cabinet standardization, miniaturization.
From Chinese patent literature CN101383489B, the binding post of realizing three row's buses is layout point-blank all, casing shoe namely bus connector not only needs to design a set of connection straight edge line, also to design a set of connection special-shaped bus, only have the cooperation of the four kinds of parts of connector by straight edge line, the connector that connects straight edge line, special-shaped bus, connection special-shaped bus to install and could realize, and must design respectively different moulds when producing these four kinds of parts, increased undoubtedly production cost.In addition, for the equal layout point-blank of the binding post of realizing three row's buses, the height that connects the connector of straight edge line must be longer than the height of the connector of special-shaped bus, just can make the setting of straight edge line do not connected the impact of special-shaped bus connector, but such structure has occupied again the space of vertical direction in power distribution cabinet undoubtedly.
Summary of the invention
When technical problem to be solved by this invention is bus tie of the prior art for the connection of bus, the binding post that can not realize separately three row's buses is layout point-blank all, thereby be used in conjunction with and must design the multi-form bus tie of two covers the problem that causes production cost higher, provide a kind of for connecting straight edge line, can make the interior busbar arrangement of power distribution cabinet neat, save the bus tie taking up room.
