The present embodiment is a kind of modified model wedge clamp, sees shown in Fig. 1 to Fig. 8, comprises base tube 1, stem stem 2, bolt 3 and cleat assembly 4; Base tube 1 comprises 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 deep-slotted chip breaker 14.Base tube is made into integration, and crimping boss is radially to projecting inward formation from the inwall in pressure pipe portion, and crimping boss axially runs 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.
The two side of each crimping boss is provided with two spacing travellers 15 protruded towards center, pressure pipe portion, and spacing traveller is arranged along the radial direction in 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 evenly arranged on the outer circumferential side of spacing hole.
The shape of stem stem is frustum, and the periphery wall of stem stem is axially arranged with four jacking sliding grooves 21 along pressure pipe portion, is also provided with multiple anticreep chisel teeth 22 in each jacking sliding groove; 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 comprises four clamps 41; The inwall of each clamp is provided with the guiding slide unit 411 with jacking sliding groove adaptation, and guiding slide unit is arranged along the axis in pressure pipe portion; The outer wall of each clamp is provided with arc clip slot 412, and the two side of each clamp is also provided with guide chute 413; The spacing traveller of each crimping boss is arranged in a corresponding guide chute, and clamp is moved along spacing traveller direction; In the present embodiment, each spacing traveller is arranged along the radial direction in pressure pipe portion, therefore clamp can only move back and forth along the radial direction in pressure pipe portion.
In the present embodiment, the axial two ends on the two side of each clamp are respectively provided with a positive stop lug boss 417, and 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 with stem stem jacking sliding groove bottom wall adaptation, and this taper stress surface is in fact also 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; Each clamp is just arranged a corresponding crimping boss, and each arc clip slot and a corresponding deep-slotted chip breaker clamping form a clamp hole 5, and the present embodiment forms four clamp holes altogether; Each through wires hole in shrouding portion is also just arranged a corresponding clamp hole.
Stem stem, under the spacing mating reaction of the guiding slide unit of its jacking sliding groove and clamp, can not rotate in pressure pipe portion, can only moving axially along pressure pipe portion.
The conical outer wall of each guiding slide unit also namely the inwall 414 of clamp be provided with multiple anticreep tooth 416, each anticreep tooth is used for engaging with the anticreep chisel teeth of 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 and make its radially outward moving 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 deep-slotted chip breaker; Specifically, each puncture is protruded along the radial direction of base tube.The existence of puncture, without the need to carrying out peeling process to insulating power cable, effectively can connect electricity.In concrete practice, if what will clamp is bare wire, then can not puncture be set.
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 also can adopt alternate manner to make; Such as in each arc clip slot and deep-slotted chip breaker, be 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; Puncture sheet comprises installation portion and thorn blade, and installation portion is inlaid in be installed in draw-in groove, and thorn blade then exposes installing card groove and forms puncture.The benefit of this structure is that puncture sheet can adopt the material different with paw to make, and especially selects and treats that clamp cable same material used is made, being conducive to obtaining better electrical gas performance.In concrete practice, can also adopt in the mode arranging screw thread in each arc clip slot and deep-slotted chip breaker, 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 is substantially identical with embodiment 1, and difference is: as shown in Figure 9, and the present embodiment also comprises current transformer 7; This current transformer comprises toroidal inductive body 71 and intelligent control module 72; In the present embodiment, intelligent control module 72 makes the ring-type with toroidal inductive body with onesize vestibule, and annular perception induction body and intelligent control module are arranged side by side and are combined to form annular, and current transformer entirety is sheathed to be fixed on the outer wall of base tube.In concrete practice, as long as make all clamp holes be arranged in the vestibule of toroidal inductive body, also namely only need to make cable pass the vestibule of toroidal inductive body.
The present embodiment has four clamp holes, but in concrete practice, only can clamp one or three electric power cables; When clamping electric power cable is that toroidal inductive body may be used for induced current or voltage signal, now can use as a common curtage instrument transformer; When clamping three electric power cables, toroidal inductive body may be used for responding to zero sequence current signal, Timeliness coverage leak current fault, now can use as a zero sequence current mutual inductor.
Intelligent control module can comprise wireless transmit/receive units, and intelligent control module sends distance host by wireless transmit/receive units to the current signal that toroidal inductive body senses, to realize accurate long-range no worker monitor.
