The quantity of radially-directed spacing hole 12 is identical with the quantity of paw 4, totally six, matrix slip pipe axially on two ends each
Arranging three radially-directed spacing holes, these three radially-directed spacing holes are for adaptive with corresponding a set of paw assembly 3；Each paw
Being positioned in a corresponding radially-directed spacing hole 12, each paw is sliding along matrix under the guide and limit effect of radially-directed spacing hole
The radial direction of pipe 11 reciprocatingly slides；
Being shaped as of plane nut 2 is ring-type, and plane nut sleeve is located on the periphery wall of matrix slip pipe 11, and is positioned at two casing pressures
Between claw assembly 3；
Each paw is provided with pressing plate portion 41, the guide runner portion 43 radially extending formation along matrix slip pipe 11 and being arranged on and leads
Driving threaded portion 44 in slide section；Threaded portion 44 is driven to be arranged on a side of guide runner portion adjacent flat nut；Pressure
The inwall in plate portion is curved, forms an arcuate groove 45, and the arcuate groove of multiple paws encloses formation one clamp hole 5.External cable position
In this clamp hole 5.
The present embodiment, in order to connect electricity on insulating power cable, is also provided with multiple puncture 42, specifically on pressing plate portion inwall
For, puncturing and be arranged on the inwall of each arcuate groove, each puncture is radially inwardly projecting along matrix slip pipe 11.The existence punctured, can
When insulating power cable not being carried out peeling and processing, still can effectively connect electricity.In concrete practice, if to be clamped is naked
Line, then can be not provided with puncturing.
In the present embodiment, each paw is the integral piece made by cast molding, and each puncture is made when cast molding；?
In concrete practice, puncture may be used without alternate manner and makes；On the inwall in pressing plate portion, such as it is provided with multiple installation draw-in groove, then
Installed in draw-in groove be inlaid in corresponding one by the die-cut puncture sheet made, puncture sheet and include installation portion and thorn blade, install
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 can adopt
Make with the material different with paw, especially select and treat that same material used by clamp cable is made, being conducive to obtaining better electrical
Gas performance.
The internal perisporium of plane nut is the smooth inner wall adaptive with matrix slip pipe periphery wall, and the periphery wall of plane nut sets
Having fastening part 21, plane nut two side ends on axial along matrix slip pipe is each provided with a flat thread portion 22, each plane
Threaded portion is provided with archimedean spiral groove, each flat thread portion then with the driving spiral shell of three paws in adjacent a set of paw assembly
Stricture of vagina portion engagement adaptation；The outer-hexagonal shape that the fastening part 21 of the present embodiment midplane nut is provided on plane nut periphery wall is tight
Gu head, it is twisted operation and uses inner hexagon spanner, shfting wrench or fork spanner；In concrete practice, described fastening part just can be adopted
Using other shape, for example with the multiple binding grooves being evenly distributed on plane nut periphery wall, it is twisted operation and uses hook type
Spanner (is commonly called as hook spanner).
In the present embodiment, each radially-directed spacing hole 12 includes rectangle slide opening 121 and anticreep slide opening 122, and rectangle slide opening sets
Putting the edge at matrix slip pipe, form a breach, anticreep slide opening connects with rectangle slide opening, and anticreep slide opening is positioned at rectangle slide opening
Inboard, anticreep slide opening and the combination of rectangle slide opening form T-shaped hole；
The anticreep that each paw guide runner portion 43 is provided with the guide part 431 being positioned in rectangle slide opening, is positioned in anticreep slide opening
Portion 432 and be positioned at the limiting section 433 outside matrix slip pipe, the guide part 431 of each paw, anti-delinking part 432 and limiting section 433 groups
It is I-shaped for closing the cross sectional shape formed；The guide part 431 of each paw and anti-delinking part 432 extend radially through each pressure along matrix slip pipe
Pawl, the inwall in the inwall of guide part 431 of each paw, the inwall of anti-delinking part 432 and pressing plate portion 41 is equipped with multiple puncture；Drive
Dynamic threaded portion is arranged on the side end wall of anti-delinking part adjacent flat nut, and the shape of anti-delinking part and anticreep slide opening are adaptive；Drive
Threaded portion is protruded and is arranged on the side end wall of anti-delinking part adjacent flat nut, so that drive threaded portion to cannot move into anti-
Try to shirk responsibility in hole.
In the present embodiment, the direction of rotation in the flat thread portion of plane nut one side is forward, the plane of another side
The direction of rotation of threaded portion is reverse, and the direction of rotation driving screw thread on each paw is and the flat thread adjacent with this paw
The direction that portion is adaptive.When this structure makes plane nut rotation, by the two of its two side ends flat thread portions, synchronize to drive
Two casing pressure claw assemblies realize clamping or releases cable.
In the present embodiment, transformer 7 is annular voltage transformer；Plane nut periphery wall is provided with a detent, should
Transformer is fixedly installed in detent, and plane nut fastening part is respectively provided with on the periphery wall being positioned at these detent both sides
Twist fastening part for one；This voltage transformer is for inducing relatively low secondary voltage from folded cable, for auxiliary for other
Equipment such as photographic head, temperature sensor, wireless transmit/receive units is helped to provide electric energy.
The present embodiment, when carrying out clamp operation, uses inner hexagon spanner, shfting wrench or fork spanner to twist plane nut；
Plane nut, in reciprocating rotation, drives its flat thread portion reciprocating rotation, and then by engaging the driving screw thread of adaptation
Portion drives and synchronizes to drive two casing pressure claw assemblies, owing to each paw can only edge under the guide and limit effect of radially-directed spacing hole 12
The radial direction matrix slip pipe moves back and forth, so that the move mode of each paw is close to each other or remote towards slip pipe center
From, thus clamp or unclamp the electric power cable being positioned in clamp hole 5.
The present embodiment is by being arranged on cable clamping at the longitudinal center line of high-voltage mutual inductor, and its gravity centre distribution is more closed
Reason, when on the overhead power line of high-altitude, is conducive to alleviating vibration；It addition, the present embodiment is driven by flat thread portion
Paw clamping electric power cable, compares with by traditional bolt assembly clamping electric power cable, particularly excellent in anti-loosening effect,
The reliability of long-term work is effectively ensured.
In the present embodiment, two casing pressure claw assemblies are clamped on same cable, have the effect of dual fail-safe, though the most a set of
In use go wrong, its service behaviour of the most another set of guarantee.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.And these
Belong to obvious change that the connotation of the present invention extended out or variation still falls within protection scope of the present invention.
