Detailed description of the invention
(embodiment 1)
The present embodiment is that a kind of modified model continues electric armour clamp, as shown in Fig. 1 to Fig. 5, including a base tube 1, Core pipe 2, two casing pressure claw assembly 3 and two plane nuts 4；It is convex that the internal perisporium of base tube is axially arranged with multiple crimping along base tube Platform 11, the inwall of each crimping boss is provided with arcuate groove 111；It is sliding that the internal perisporium of base tube is axially additionally provided with multiple location along base tube Groove 12；Core pipe and base tube are arranged concentrically and are positioned at base tube tube chamber；The periphery wall of core pipe is provided with multiple along core pipe radial convex Going out the support flange 21 extended, each outboard end supporting flange is positioned in a corresponding positioning runner, thus core pipe is supported It is positioned in the tube chamber of base tube；The tube wall of core pipe is provided with the spacing slide opening of multiple radial direction 22, and each radially spacing slide opening is all along core Pipe extend radially through core tube wall；The internal perisporium of core pipe is provided with the annular gear platform 23 of inwardly projecting formation.
Each casing pressure claw assembly includes multiple paw 5, and in the most each casing pressure claw assembly, the quantity of paw can be one to four Selecting as required between individual, the quantity of the most spacing slide opening is then identical with the total quantity of paw, and the present embodiment selects four； Every casing pressure claw assembly and a corresponding plane nut are adaptive；Each paw includes that pressing plate portion 51, inwall from pressing plate portion are to convex Go out the guide runner portion 52 formed and the driving threaded portion 53 being arranged in guide runner portion；Pressing plate portion axially prolongs along base tube Stretching, guide runner portion radially extends along core pipe；The outer wall in each paw pressing plate portion is provided with arc clip slot 511；Each pressing plate portion Between base tube inwall and core tube wall, each guide runner portion inserts on core pipe in a corresponding spacing slide opening of radial direction, respectively Threaded portion is driven to stretch in the tube chamber of core pipe；Each paw under the guide and limit effect of radially spacing slide opening along the footpath of core pipe To reciprocatingly sliding.
In the present embodiment, the radial cross-sectional shape of each radially spacing hole is I-shaped, the radial section shape in each guide runner portion Shape is adaptive with radial direction spacing hole I-shaped；In concrete practice, radially spacing hole and the radial section in guide runner portion Shape also can be selected for other shape, such as circle, rectangle, square, as long as just having radially-directed and limit effect OK.
In the present embodiment, the arcuate groove of a corresponding crimping boss is just arranged by the arc clip slot of each paw, and this paw The arcuate groove clamping of arc clip slot and this crimping boss forms a clamp hole 6, and each clamp hole is for one electric lines of force of clamping Cable.In the present embodiment, the size in each clamp hole can be different, for clamping the cable of different thicknesses.
Two plane nuts all rotate and are arranged in core pipe tube chamber, the both sides of two plane nut separation annular gear platforms；Each set The threaded portion that drives in paw assembly is respectively positioned on the corresponding plane nut side away from annular gear platform；Each plane nut Periphery wall and core inside pipe wall slide adjacent, and the center of each plane nut is provided with fastening part 42；One side of each plane nut Sliding adjacent with annular gear platform, another side is provided with to engage with the driving threaded portion of each paw in corresponding a set of paw assembly and fits The flat thread portion 41 joined；Flat thread portion is annular, and flat thread portion is provided with archimedean spiral groove；Each paw group The thread groove that driving threaded portion is provided with and this archimedean spiral groove is adaptive of part, each driving threaded portion is arranged on place and leads A side to slide section adjacent flat nut.
The present embodiment, in order to connect electricity on insulating power cable, is also provided with multiple puncture in each arcuate groove and each arc clip slot 7；Specifically, respectively puncture along core pipe radially protruding.The existence punctured, can not shell insulating power cable Skin processes, and can effectively connect electricity.In concrete practice, if to be clamped 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 crimping boss and base tube are by casting Shaping the integral piece made, each puncture is made when casting forming；In concrete practice, puncture and may be used without alternate manner Make；In each arcuate groove and each arc clip slot, such as it is provided with multiple installation draw-in groove, then by the die-cut puncture made Sheet is inlaid in corresponding one and installs in draw-in groove, punctures sheet and includes installation portion and thorn blade, and installation portion is inlaid in installation draw-in groove, Thorn blade then exposes installation draw-in groove and forms puncture.The benefit of this structure is to puncture sheet to use the material different with paw Make, especially select and treat that same material used by clamp cable is made, being conducive to obtaining preferable electric property.
The fastening part of the present embodiment midplane nut is interior hexagonal shape fastener hole or interior hexagonal shape binding groove, and it is twisted operation and adopts Use inner hexagon spanner；In concrete practice, described fastening part just can use other shape, the most square or in-line or prunus mume (sieb.) sieb.et zucc. Flower-shape, all can select.
The present embodiment can form four clamp holes, is especially suited as branch connection gold utensil and uses.
In the present embodiment, each plane nut, when reciprocating rotation, drives its flat thread portion reciprocating rotation, so by with In the corresponding a set of paw assembly of driving threaded portion driving that the engagement of this flat thread portion is adaptive, each paw moves, due to each paw Under the guide and limit effect of radially spacing slide opening, the radial direction only along core pipe moves back and forth, so that respectively set paw group In part the move mode of paw be close to each other towards core tube hub or away from, thus unclamp or clamp and be positioned in each clamp hole Electric power cable.
The present embodiment gravity centre distribution is relatively reasonable, when on the overhead power line of high-altitude, is conducive to alleviating vibration；Separately Outward, the present embodiment drives paw clamping electric power cable by flat thread portion, and by traditional bolt assembly clamping electric power Cable is compared, particularly excellent in anti-loosening effect, and the reliability of long-term work is effectively ensured.It addition, this enforcement Example by same cable is used two casing pressure claw assemblies clamp, there is 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.
(embodiment 2)
The present embodiment and embodiment 1 are essentially identical, and difference is: as shown in Figure 6, in the present embodiment outside base tube The most sheathed current transformer 8 that is fixed with on perisporium, the quantity of described crimping boss and paw is all three, therefore the present embodiment Can form three clamp holes, for three phase cables of clamping, now the present embodiment entirety can be as high pressure zero-sequence current Transformer uses, for detecting the existence of leakage current, to find leak current fault in time.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not to this The restriction of the embodiment of 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 this Belong to obvious change that the connotation of the present invention extended out a bit or variation still falls within protection scope of the present invention.
