Penetrating cable clampTechnical field
The present invention relates to electric armour clamp field, be specifically related to a kind of penetrating cable clamp.
Background technology
Insulated cable is the important component part of power system, and in order to realize the fast and safely connection of insulated cable, customary insulation penetrating cable clamp is as Quick connection part.The insulation puncture line clamping of prior art is mainly made up of insulation upper cover, insulation lower cover, arc seal gasket, piercing blade screw rod fastening assembly, wherein, threaded fastener assembly includes running through the screw rod of insulation upper cover and insulation lower cover and being socketed in the nut of screw rod one end, nut is provided with the torque nut of fracture after clamping, insulation upper cover and insulation lower cover form two clamp grooves, and piercing blade is arranged in clamp groove and is wrapped in arc seal gasket.During use, first main line is placed in one in a clamp groove, branch line is placed in another clamp groove, then with instruments such as spanners, torque nut is tightened, when the piercing blade in clamp groove pierces through the insulating barrier of main line and branch line, torque nut Automatic-falling, now completes the electrical connection of main line and branch line.Owing to adopting insulation puncture line clamping need not peel off the insulated hull of electric wire, therefore the application of insulation puncture line clamping is widely.
The penetrating cable clamp of said structure, the size between two clamp grooves is fixed, it is impossible to meet the main line of different spacing and the connection of branch line, additionally, by the restriction of wire clamp overall dimensions, the distance between two clamp grooves is relatively small, it is impossible to meet the master of big span, branch line connects.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of penetrating cable clamp, the master of different spacing, branch line connection can not only be adapted to, and adapt to the master of big span, branch line connection.
nullThe present invention solves the problems referred to above by techniques below means: a kind of penetrating cable clamp，Including base plate、It is vertically set on the rack on base plate、It is socketed in the sleeve outside rack and level implements sleeve and the tooth bar engaged with rack，Described rack and base plate are rotationally connected，Rack top is provided with torque nut，Described tooth bar is two that front and back are arranged，Tooth bar is provided with activity piercing blade away from rack one end，Just activity piercing blade is provided with fixing piercing blade，Described fixing piercing blade is connected with base plate by slide block，Described base plate is provided with chute along tooth bar length direction，Described slide block is connected with slide，Before and after described base plate, both sides are provided with and move towards kidney slot that is consistent and that connect with chute with chute，Described slide block and chute are by sequentially passing through kidney slot、The bolt of chute and slide block is attached locking，Described rack and base plate are undertaken rotating locking by bearing pin.
Further, described base plate is provided with rack support, described tooth bar traverse rack support.
Further, described tooth bar is provided with limited block away from activity piercing blade one end.
Further, described rack support is made up of NULL, and described sleeve is made up of insulant.
Further, described base plate being provided with insulating boot, chute is just being provided with the groove moving towards consistent with chute by described insulating boot top.
Beneficial effects of the present invention: the penetrating cable clamp of the present invention, by forming clamp groove between fixing piercing blade and activity piercing blade, by adjusting slide block position in chute, change the position of two fixing piercing blades, and then change the distance between two clamp grooves, in order to adapt to the master of different spacing, branch line connects, simultaneously, distance adjustable extent between two clamp grooves is relatively large, adapts to the bigger master of span, branch line connection.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.

Detailed description of the invention
nullBelow with reference to accompanying drawing, the present invention is described in detail，As shown in Figure 1-2: a kind of penetrating cable clamp，Including base plate 1、It is vertically set on the rack 2 on base plate、It is socketed in the sleeve 3 outside rack and level implements sleeve and the tooth bar 4 engaged with rack，Described rack and base plate are rotationally connected，Rack top is provided with torque nut 5，Described tooth bar is two that front and back are arranged，Tooth bar is provided with activity piercing blade 6 away from rack one end，Just activity piercing blade is being provided with fixing piercing blade 7，Described fixing piercing blade is connected with base plate by slide block 8，Described base plate is provided with chute 9 along tooth bar length direction，Described slide block is connected with slide，Before and after described base plate, both sides are provided with and move towards kidney slot 10 that is consistent and that connect with chute with chute，Described slide block and chute are by sequentially passing through kidney slot、The bolt 11 of chute and slide block is attached locking，Described rack and base plate are undertaken rotating locking by bearing pin 12.During use, the first step: move slide block according to the span of master, branch line and adjust the distance between two fixing piercing blades, with bolt, slide block and chute are fixed together after adjustment；Second step: respectively master, branch line are placed on activity piercing blade and between the two clamp grooves that fixing piercing blade is formed, moment nut rotation is driven with spanner, rotated by torque nut driven gear bar, rack promotes tooth bar to stretch out and compresses main, branch line, when torque nut ruptures, insulating barrier main, branch line is just pierced, now with bearing pin lock gear bar, prevent rack from rotating, so just complete puncture main, that prop up and connect.The penetrating cable clamp of this structure, by forming clamp groove between fixing piercing blade and activity piercing blade, by adjusting slide block position in chute, change the position of two fixing piercing blades, and then change the distance between two clamp grooves, in order to adapt to the master of different spacing, branch line connects, simultaneously, distance adjustable extent between two clamp grooves is relatively large, adapts to the bigger master of span, branch line connection.
As the further improvement of technique scheme, described base plate being provided with rack support 13, described tooth bar is through rack support, and tooth bar is played firm effect by rack support.
As the further improvement of technique scheme, described tooth bar is provided with limited block 14 away from activity piercing blade one end, it is to avoid tooth bar slips from sleeve.
As the further improvement of technique scheme, described rack support 13 is made up of NULL, and described sleeve 3 is made up of insulant, the rack support that NULL is made, and can completely cut off magnetic loop, saves energy.
Further improvement as technique scheme; described base plate is provided with insulating boot 15; chute is just being provided with the groove 16 moving towards consistent with chute by described insulating boot top, and insulating boot plays insulation protection effect, and the convenient master of groove, branch line enter in clamp groove through insulating boot.
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from objective and the scope of technical solution of the present invention, it all should be encompassed in the middle of scope of the presently claimed invention.
