Existing method, differ too big lead for such cross section exactly, like that just adopting directly is wrapped in branch line above the main line, be difficult to the reliability that guarantees that lead continues like this, not that very large lead connects and differ for the cross section, just continue and connect with wire clamp with striding the footpath lead, this wire clamp is made of wire clip body and screw, and wire clip body by up and down two have the gland of perforation formed, screw passes two glands and screws and make gland can be fixed lead, and present wire clamp is a symmetric design, all be provided with the indent of the corresponding arc in a pair of position up and down on two glands, form a pair of clamp groove that supplies lead to pass in the time of pressing up and down between the indent of two glands, because up and down to be formed for compressing the indent of lead all be equally big to two glands, therefore conductor cross-section differ bigger in, the little lead in cross section sliding phenomenon just may occur even folder occur not tightly or situation about can't clip, it is unreliable to install.

Summary of the invention

The purpose of this utility model is, provides a kind of and the footpath lead of striding reliable, easy to use is installed is continued and use wire clamp.

The utility model is achieved by the following scheme: a kind of footpath lead of striding continues and uses wire clamp, comprise upper press cover, lower cover, screw, upper press cover and lower cover all are provided with perforation and a pair of indent, screw passes perforation is compressed upper press cover and lower cover, the indent of two glands forms a pair of clamp groove that supplies lead to pass through, it is characterized in that described upper press cover has at least a pair of size different with indent on the lower cover, form small one and large one two clamp grooves after the pressing.

This is provided with makes the indent size inconsistent, the size of an indent of minimum change just can make the different formation of two clamp groove sizes dissymmetrical structure, the connection of the lead that differs greatly for the cross section, the smaller clamp groove of size passes through for the little lead in cross section, pass through for the bigger lead of section ratio and size is bigger, like this since, lead is not just had big slip at the clamp groove in the process that compresses, it is fine to compress effect, uses easily, and very reliable is installed.

Of the present utility modelly further be set to: described upper press cover be provided with one with the arc jet-bedding relative and parallel with indent to punch position.

This is provided with described and relative to punch position and parallel with indent, be exactly loam cake perforation is provided with in the ability jet-bedding, jet-bedding and indent are in the same way, because original product does not have jet-bedding, therefore loam cake is under outwards oblique after synthetic with the indent partial pressure to the ambient pressure of perforation when screw compresses, outwards the extruding indent is to cause distortion, the effect that influence compresses, and now the arc jet-bedding is arranged on relative to punch position and parallel with indent, it is identical with compaction direction or inside after the pressure of jet-bedding part and indent part synthesizes, so just can not make the indent distortion,, not influence the reliability that compresses even distortion also is the horizontal stretching, extension of indent, strengthened compressing effect, it is very reliable, easy to use that such setting is installed product, need not to do too big adjustment.

Of the present utility modelly further be set to: also have press strip on the described upper press cover, press strip is provided with and through hole and width with the nut diameter identical holddown groove relative to punch position.

This top that is arranged on upper press cover also is provided with a press strip that has holddown groove, because present wire clamp is by screw in compression, screw bolt and nut to be rotated simultaneously in the time of fixing, or set bolt screws nut again, and press strip is provided with a holddown groove that width is identical with the nut diameter now, holddown groove meeting hold-doun nut in the process that compresses, and it is just passable only need to screw nut, use more conveniently, and strengthened the effect that compresses to a certain extent.

Above-mentioned structure is arranged to dissymmetrical structure with two clamp grooves, make and stride the footpath lead and continue and tangible slip can not occur with wire clamp lead when compressing, it is fine to connect effect, be provided with arc jet-bedding and the press strip that has holddown groove simultaneously, jet-bedding has been adjusted pressure direction, and the setting of press strip makes and need not the two ends operation when installing, all settings make stride the footpath lead continue with wire clamp install more reliable, use convenient.
