Background technology

Bus is the usual means for powering to the load in distribution system.Fixing for bus, the main form that adopts bus clip at present, this bus clip is insulating property (properties), bus can be fixed on reliably to power distribution cabinet etc. needs on fixing position.CN202651729U discloses a kind of vertical bus bracing frame, and it utilizes bolt component that two bus clips are directly tightened, thereby realizes the clamping to bus, but its spacing is indefinite, can only rule of thumb determine, and structure is stable not for the pretightning force of bus; CN202772526U discloses a kind of bus-bar supporting piece, and it has rib, for space distance control and play the effect that improves stability, but coordinates due between rib and screw, and structure is easily damaged, and cannot take into account the requirement of insulating properties and firmness; And the structure of its bus duct stability for the installation of bus is also not high enough.CN202712784U discloses a kind of novel bus fixture, and it utilizes upper and lower two bus clips that bus is surrounded, thereby plays the effect of strengthening firm degree, but its heat dissipation ventilation weak effect.CN203039241U, CN202712695U all disclose a kind of bus clip, the gap of heat radiation in the middle of its upper and lower bus clip has, but there is no rib, clamping for bus can only be by the mode of the nut that tights a bolt, need to dependence experience determine pretightning force equally, and form impact for the structure of bus itself; More importantly, bolt itself is exposed, forms potential safety hazard.

Utility model content

In order to overcome above-mentioned defect, the utility model aims to provide a kind of bus clip, and it can improve the stressing conditions of bus, be convenient to heat radiation, can guarantee firmness and reliability that bus is installed, improve the fail safe of distribution process, and be convenient to tighten fixing, easily install.

The scheme adopting is as follows:

A kind of bus clip, comprise fixture block, lower fixture block, pillar, internal threaded column, wherein, upper fixture block is identical with lower fixture block structure and opposed up and down, internal threaded column is hollow tubular structure and has inner peripheral surface, the two ends up and down place of described inner peripheral surface has internal thread, thereby described pillar has longitudinal hole, to make it be also hollow tube-shape structure, described internal threaded column be inserted through the through hole of described pillar and make internal threaded column and described pillar between have and can prevent that the two from coordinating in relative rotation;

On the upper fixture block medial surface relative with lower fixture block, be relatively provided with bus duct and brace table, bus duct and brace table are arranged alternately, bus duct is used for inserting bus, the central part of brace table be provided with can with described pillar anti-rotation the pillar hole that coordinates, thereby pillar can be arranged on to anti-rotation between fixture block and lower fixture block; Bottom center at pillar hole is provided with the manhole relative with the inner peripheral surface of internal threaded column, screw can pass respectively the screw-internal thread fit at upper fixture block and the described manhole of lower fixture block and the two ends up and down of internal threaded column, thereby upper fixture block, pillar and lower fixture block can be fixed together, and therefore the bus being plugged in bus duct can be fixed.

Valuably, the shape of cross section of the lateral surface of described internal threaded column is the first convex polygon; The shape of cross section of the longitudinal hole of pillar and the lateral surface of described internal threaded column match.

Valuably, have protruding boss in the both ends of the surface of described pillar, the shape of cross section of the lateral surface of this boss is the second convex polygon; The second convex polygon of the shape of described pillar hole and described boss matches, thereby make pillar and brace table have anti-rotation, coordinates.

Valuably, described the first convex polygon is regular hexagon.

Valuably, described the second convex polygon is square.

Valuably, the two ends of internal threaded column are exposed to the through hole of pillar, in the bottom of pillar hole, be provided with internal threaded column expose the internal threaded column hole of two ends form fit.

Valuably, the quantity of pillar is three, and the quantity of bus duct is four.

Valuably, the shape of cross section of the lateral surface of pillar is square.

Valuably, in the bottom of bus duct, be provided with the rectangle projection that can coordinate with the location notch of bus sidepiece.

Valuably, the height of described rectangle projection is less than the degree of depth of described bus duct.

By above-mentioned bus clip, due to the existence of pillar, improved the stressing conditions of bus, and between upper and lower fixture block, there is gap, be convenient to heat radiation, and there is pillar in the outside of threaded post, the effect of isolated threaded post be can play, reliability and fail safe improved; And because internal threaded column, pillar are all coordinating of anti-rotation with upper and lower fixture block, be therefore convenient to tighten fixing, easily install.And bus clip of the present utility model can be changed height pillar lining and interior specification pincette, fixes thereby can convert various buses.
