Abstract

The utility model discloses novel safe bus-bar clamp. The bus-bar clamp comprises an upper clamp block, a lower clamp block and screw bolts, wherein the upper clamp block and the lower clamp block are connected by the screw bolts; three recessed upper wire clamping grooves are arranged on the lower side of the upper clamp block and each is provided with three upper bus-bar bayonets; three recessed lower wire clamping grooves are arranged on the upper side of the lower clamp block and each is provided with three lower bus-bar bayonets; the three upper wire clamping grooves correspond to the three lower wire clamping grooves, and the three upper bus-bar bayonets correspond to the three lower bus-bar bayonets. According to the utility model, the serious accident that metal bus-bars escape from the wire clamping groove when there is a short-circuit fault is prevented; the safe bus-bar clamp is simple in structure, simple in size and convenient for use; a bolt screw sleeve structure is adopted, and the depth of the bots is adjustable so as to adapt to metal bus-bars of various specifications, so that the bus-bar clamp is convenient for popularization.

Description

A kind of new type of safe Bus line cramp

Technical field

The utility model relates to a kind of power equipment Bus line cramp, relates in particular to a kind of new type of safe Bus line cramp.

Background technology

Bus line cramp of the prior art is not respectively equipped with the groove corresponding with shape of generatrix, what mostly install is simple smooth groove, continuous increase along with electricity consumption current strength, high frequency can occur owing to the effect of electric current and laterally tremble in this Bus line cramp of the prior art when work, thereby cell wall is produced lateral impact forces, laterally vibration, thereby cell wall is produced lateral impact forces, when the metallic bus bar of outermost side when direction swings laterally, can be to the cell wall of outermost side and the outside stretching torsion of position generation on every side thereof, because the cell wall of outermost side is partial to an a corner, few with the connection relationship at position on every side, lack adjacent regions and limit its outside distortion, after this position is subject to outside impulsive force, can produce distortion by a relatively large margin, add the tension of non-metal insulating material, torsional property is poor, easily appear at certain plane of weakness fracture, in case this position fracture, the cell wall of outermost side will be shifted, come off, then the live metal bus of outermost side will lose constraint and jump out groove, and its consequence is hardly imaginable.

Along with in recent years economy, industrial expansion, the continuous increase of electricity consumption current strength, the impulsive force that cell wall need to bear is increasing, and above-mentioned danger is also increasing, and the problems referred to above more and more need to solve.

Summary of the invention

The purpose of this utility model provides a kind of new type of safe Bus line cramp with regard to being in order to address the above problem.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The utility model comprises fixture block, lower fixture block and bolt, be connected by described bolt between described upper fixture block and the described lower fixture block, be provided with the upper cable clamping interface of three indents below the described upper fixture block, be provided with three Up Highway UHW bayonet sockets in each described upper cable clamping interface, be provided with the lower card line groove of three indents above the described lower fixture block, be provided with three Down Highway bayonet sockets in each described lower card line groove, three described upper cable clamping interfaces are corresponding with three described lower card line grooves respectively, and three described Up Highway UHW bayonet sockets are corresponding with three described Down Highway bayonet sockets respectively.

Particularly, described bolt is four, lays respectively between the adjacent described upper cable clamping interface.

The beneficial effects of the utility model are:

The utility model is because the peripheral looping frame structure of whole Bus line cramp, front and back link to each other, integral rigidity strengthens, each position is supported mutually with opposing external force, check and balance to reduce distortion, namely the degree of distortion can be subject to restriction, the constraint of adjacent regions, and the ability that the cell wall of outermost side is withstood shocks strengthens, the degree that this position is subject to deforming when bus impacts reduces the danger reduction of fracture.

Therefore, metallic bus bar was jumped out the abominable accident of cable clamping interface when Bus line cramp of the present utility model can guarantee to avoid short circuit current, and simple in structure, volume is small and exquisite, easy to install and use, owing to adopting the bolt thread tube-in-tube structure, the degree of depth that can adjusting bolt, therefore can be adapted to the metallic bus bar of all size, be convenient to promote.

Description of drawings

Fig. 1 is the structural representation of new type of safe Bus line cramp described in the utility model;

Fig. 2 is that this adapts to the structural representation after novel described new type of safe Bus line cramp is installed bus.

Among the figure: fixture block, the upper fixture block of 2-, 3-bolt, 4-bus, the upper cable clamping interface of 5-, 6-Up Highway UHW bayonet socket, 7-lower card line groove, 8-Down Highway bayonet socket under the 1-.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1: comprise fixture block 2, lower fixture block 1 and bolt 3, be connected by bolt 3 between upper fixture block 2 and the lower fixture block 1, be provided with the upper cable clamping interface 5 of three indents below the upper fixture block 2, be provided with three Up Highway UHW bayonet sockets 6 on each in the cable clamping interface 5, be provided with the lower card line groove 7 of three indents above the lower fixture block 1, be provided with three Down Highway bayonet sockets 8 in each lower card line groove 7, three upper cable clamping interfaces 5 are corresponding with three lower card line grooves 7 respectively, and three Up Highway UHW bayonet sockets 6 are corresponding with three Down Highway bayonet sockets 8 respectively.Bolt 3 is four, lays respectively between the adjacent upper cable clamping interface 5.

As shown in Figure 2: even this structure is in the situation that just in case short circuit current, because the instantaneous increasing of current strength, wherein place's outermost fracture of upper fixture block 2 or lower fixture block 1, this place also still fixedly is linked as with another fixture block by the bolt thread tube-in-tube structure, thereby still can not be shifted, come off, so the bus 4 of metal still can be clamped by this place, prevent that the bus 4 of metal from jumping out between cable clamping interface 5 and the lower card line groove 7.Angle from probability, upper fixture block 2 and lower fixture block 1 both outermost simultaneously probability of fracture are very little even are zero, therefore, the bus 4 of metal was jumped out the abominable accident between cable clamping interface 5 and the lower card line groove 7 when Bus line cramp described in the utility model can guarantee to avoid short circuit current, and simple in structure, and volume is small and exquisite, easy to install and use, owing to adopting the bolt thread tube-in-tube structure, therefore the degree of depth that can adjusting bolt 3 can be adapted to the bus 4 of all size metal.
