Detailed description of the invention
(embodiment 1)
The present embodiment is a kind of wedge clamp, sees shown in Fig. 1 to Fig. 8, including base tube 1, stem stem 2, bolt 3 and cleat assembly 4; Base tube 1 includes pressure pipe portion 11 and is positioned at the shrouding portion 12 of one end, pressure pipe portion; The shape in pressure pipe portion is circular, and the inwall in pressure pipe portion is provided with crimping boss 13, and the inwall of crimping boss is provided with arcuate groove 14. Base tube is made into integration, and crimping boss projects radially inwards formation from the inwall in pressure pipe portion, and crimping boss axially penetrates through the inwall in pressure pipe portion along pressure pipe portion.
In the present embodiment, pressure pipe portion is provided with four crimping boss, and these four crimping boss are evenly distributed on the inwall in pressure pipe portion along the circumference in pressure pipe portion.
Each two side crimping boss is provided with two spacing travellers 15 protruded towards center, pressure pipe portion, and spacing traveller is radially arranged along pressure pipe portion.
Shrouding portion 12 is provided with through wires hole 16 and spacing slide opening 17;
In the present embodiment, shrouding portion is provided with a spacing slide opening and four through wires holes; Spacing slide opening is arranged on the center in shrouding portion, and through wires hole is uniformly arranged on the outer circumferential side of spacing hole.
Stem stem be shaped as frustum, the periphery wall of stem stem is axially arranged with along pressure pipe portion four jacking sliding grooves 21, each jacking sliding groove is additionally provided with multiple anticreep chisel teeth 22; The center of stem stem is axially arranged with center screw 23 along pressure pipe portion. The diapire of each jacking sliding groove is as taper electrolysis 211.
Cleat assembly includes four clamps 41; The guiding slide unit 411 that the inwall of each clamp is provided with and jacking sliding groove is adaptive, axially arranged along pressure pipe portion of guiding slide unit; The outer wall of each clamp is provided with arc clip slot 412, and the two side of each clamp is additionally provided with guide chute 413;Each spacing traveller crimping boss is arranged in a corresponding guide chute so that clamp moves along spacing traveller direction; In the present embodiment, each spacing traveller being radially arranged along pressure pipe portion, therefore clamp moves back and forth only along the radial direction in pressure pipe portion.
In the present embodiment, the two side of each clamp being axially respectively arranged at the two ends with a positive stop lug boss 417, these two positive stop lug boss clampings form described guide chute 413.
In the present embodiment, each guiding slide unit has the taper stress surface adaptive with stem stem jacking sliding groove bottom wall, and this taper stress surface substantially also serves as the inwall 414 of clamp; When the guiding slide unit of each clamp is arranged in stem stem jacking sliding groove, the outer wall 415 of clamp is parallel with the inwall 131 of a corresponding crimping boss; A corresponding crimping boss is just arranged by each clamp, and each arc clip slot and a corresponding arcuate groove clamping form a clamp hole 5, and the present embodiment forms four clamp holes altogether; A corresponding clamp hole is also just arranged by each through wires hole in shrouding portion.
Stem stem is under the spacing mating reaction of the guiding slide unit of its jacking sliding groove and clamp, it is impossible to rotate in pressure pipe portion, only along moving axially of pressure pipe portion.
Each conical outer wall of guiding slide unit namely the inwall 414 of clamp are provided with multiple anticreep tooth 416, and each anticreep tooth engages for the anticreep chisel teeth with stem stem, anti-skidding anti-retrogression.
Swivel bolt pulls stem stem to move towards the direction close to shrouding portion; Stem stem pushes the guiding slide unit of each clamp by the taper electrolysis in jacking sliding groove, and then promotes each clamp to make its being moved radially outward along pressure pipe portion, thus clamping is arranged in the electric power cable in clamp hole.
The present embodiment, in order to connect electricity from insulating power cable or promote chuck strength, is also provided with multiple puncture 6 in each arc clip slot and arcuate groove; Specifically, the radially protruding along base tube is respectively punctured. The existence punctured, it is possible to without insulating power cable is carried out peeling process, can effectively connect electricity. In concrete practice, if what to clamp is bare wire, then can be not provided with puncturing.
In the present embodiment, each paw is the integral piece made by casting forming, and each puncture is made when casting forming; In concrete practice, puncture may be used without alternate manner and makes; In each arc clip slot and arcuate groove, be such as provided with multiple installation draw-in groove, then install in draw-in groove be inlaid in corresponding one by the die-cut puncture sheet made; Puncturing sheet include installation portion and sting blade, installation portion is inlaid in installation draw-in groove, and thorn blade then exposes installation draw-in groove and forms puncture. The benefit of this structure is to puncture sheet the material different with paw can be adopted to make, and especially selects and treats that same material used by clamp cable is made, being conducive to obtaining preferably electric property. In concrete practice, it is also possible to adopt in the mode being threaded in each arc clip slot and arcuate groove, also can improving clamping sigma compactness energy.
The present embodiment has following Advantageous Effects: (1) operation is comparatively laborsaving, has good anti-loosening effect; .
(embodiment 2)
The present embodiment and embodiment 1 are essentially identical, are different in that: as shown in Figure 9, and the present embodiment also includes current transformer 7; This current transformer includes toroidal inductive body 71 and intelligent control module 72; In the present embodiment, intelligent control module 72 is made has the ring-type of onesize vestibule with toroidal inductive body, and annular perception sensing body and intelligent control module are arranged side by side combination and form annular, on the overall sheathed outer wall being fixed on base tube of current transformer.In concrete practice, as long as making all clamp holes be arranged in the vestibule of toroidal inductive body, namely have only to so that the vestibule of cable traverse toroidal inductive body.
The present embodiment has four clamp holes, but in concrete practice, it is possible to only or three electric power cables of clamping; When one electric power cable of clamping is that toroidal inductive body may be used for faradic current or voltage signal, now can use as a common curtage transformer; When clamping three electric power cables, toroidal inductive body may be used for sensing zero sequence current signal, finds leak current fault in time, now can use as a zero sequence current mutual inductor.
Intelligent control module can include wireless transmit/receive units, and the current signal that intelligent control module is sensed toroidal inductive body by wireless transmit/receive units sends distance host to, to realize the long-range no worker monitor of precision.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not the restriction to embodiments of the present invention. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive. And the apparent change that these connotations belonging to the present invention are extended out or variation still fall within protection scope of the present invention.
