Description
Technical field
The utility model belongs to low voltage electrical equipment field, relates to a kind of low-voltage cabinet, particularly a kind of syndeton of low-voltage cabinet copper bar.
Background technology
Low-tension switch cabinet is provided with the components and parts such as switch, contactor, frequency converter, soft initiator usually, connects the general wire that adopts and connects, directly wire can be accessed component body into and out of on end or terminal board between the components and parts that current class is less.The components and parts that current class is larger then adopt copper bar to connect, and component body upper and lower end all can draw one section of copper bar, and copper bar upper punch has circular connecting hole, to be connected with other components and parts.Copper bar rushes to standard circular hole separately, the connection that bolt carries out between copper bar can be adopted.
Above-mentioned copper bar is when actual installation, connection between copper bar adopts outer-hexagonal bolt to connect, bimanualness is needed when fastening bolt, one end spanner of screw rod blocks by a hand, and another hand screws up with a wrench nut, operates easy not, and when components and parts installation site is near switch cubicle both sides, because cabinet both sides are all provided with cabinet space bar or limit screen, movable limited space, very inconvenient during bolt on fastening copper bar.
In bus-bar room, main busbar installation site is that front and back are arranged successively, and the space in general bus-bar room is very limited, fastening be positioned at middle copper bar connecting bolt time, fastening very inconvenient.Both taken a large amount of artificial, turn increased on-the-spot installation production cost.When low-tension switch cabinet is installed by wall, be unfavorable for user maintenance, maintenance.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of syndeton of low-voltage cabinet copper bar, under the prerequisite not affecting connection reliability, make the connection of copper bar easier, one hand can complete, solve the activity space deficiency because copper bar position causes, the problem of installation and maintenance difficulty.
To achieve these goals, the technical scheme that the utility model is taked is:
The syndeton of described low-voltage cabinet copper bar, comprise copper bar, connecting bolt and nut, the screw portion of described connecting bolt comprises the square screw rod of close bolt head and is positioned at the circular screw rod of screw rod tail end, described copper bar is provided with the square attaching apertures matched with described square screw rod, and described nut is arranged on described circular screw rod and compresses described copper bar.
Spring washer is provided with between described nut and described copper bar.
Described spring washer one side is fixedly connected with described nut, and another side is evenly distributed with some anti-slop serrations.
Be matched in clearance between described square screw rod and described square attaching apertures.
Described square attaching apertures edge is provided with the flange stretched out towards described nut direction, and after described nut is fastened, described flange encases described circular screw rod side.
Adopt technique scheme, square attaching apertures has coordinated with square screw rod the effect being fixedly connected with bolt, and such operator singlehanded just energy clamp nut, connected mode simply has the reliability not affecting connection.It also avoid the activity space deficiency solved because copper bar position causes, the problem of installation and maintenance difficulty simultaneously.
Spring washer plays and applies pressure to nut, prevents it from vibrating the effect of rocking.
Spring washer is fixed on nut, coordinates anti-slop serrations, can effectively prevent nut from getting loose after tightening, enhance the reliability of syndeton, fail safe.
Square structure adopts matched in clearance just can realize fixing to connecting bolt in fastener cycle, and prevent the effect of screws, the requirement on machining accuracy of square shaped connecting hole also can reduce, and manufactures use all very simple.
Encase circular screw rod, the screw thread on circular screw rod and have very large frictional force between flange by clamp nut extruding flange, can play further and prevent bolt from getting loose, connection is more firmly acted on.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As Figure 1-5, the utility model provides a kind of syndeton of low-voltage cabinet copper bar, comprises copper bar 6, connecting bolt 7 and nut 5.The bolt head 1 of connecting bolt 7 is circular, and screw rod is then divided into two sections, and one section is square screw rod 2 near bolt head 1, and the other end is circular screw rod 3 at screw rod tail end.Copper bar 6 is provided with square attaching apertures 8, and square screw rod 2 inserts square attaching apertures 8 matched in clearance with it.Such connecting bolt 7 is after insertion square attaching apertures 8, and energy is fastening nut 5 directly, need not block with spanner.The length of square screw rod 2 should not be greater than copper bar 6 superpose after gross thickness, otherwise cannot to tight a bolt.If the length of square screw rod 2 is longer than single copper bar 6 thickness, can locate copper bar 6, prevent two copper bars 6 from relatively rotating.
5, nut is arranged on to be established on threaded circular screw rod 3.Nut 5 is fixed with spring washer 4 towards copper bar 6 one side, is evenly provided with some anti-slop serrations at spring washer 4 towards the one side of copper bar 6.Spring washer 4 energy increasing friction force, prevents bolt from loosening because vibration is rocked, improves the reliability of this syndeton, fail safe.For preventing damaging copper bar 6, a plain washer can be added between spring washer 4 and copper bar 6, reducing the pressure that copper bar 6 is subject to.
The flange stretched out towards nut 5 direction can also be stamped out at square attaching apertures 8 edge.After nut 5 is fastened, flange, by nut 5 crimp, encases circular screw rod 3 side.There is very large frictional force between screw thread on circular screw rod 3 and flange, play and prevent bolt from getting loose, connection is more firmly acted on.
This syndeton can make copper bar 6 realize singlehanded clamp nut 5, copper bar 6 is connected more easy.Especially, when user maintenance, maintenance are subject to the restriction of cabinet operating space, effect is more obvious, reduces operation easier, saves cost of labor.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
