Description

A kind of for the penetrating cable clamp from power transmission line electricity taking
Technical field
The utility model to relate under a kind of prerequisite not changing transmission line from the lv power cable power taking with insulating sleeve and completes the penetrating cable clamp of powering to equipment.
Background technology
Transmission line needs sometimes some measuring equipments are installed, some measuring equipment needs from power taking transmission line, and general lv power cable all has insulating sleeve, when there is no exposed Gong binding post near the installation site of measuring equipment, way be in the past break cable insulating sleeve and make contact at cut place power supply draw after access device power.Not only there is the possibility of loose contact in this way, and destroys the integrality of cable, also has in order to handling safety needs to cut off the electricity supply to carry out.
The patent No. is that the Chinese utility model patent of ZL200820057939.1 discloses " a kind of insertion wire clip for conductive wire ", this penetrating cable clamp Problems existing is: wire clamp and conductor rely on screw thread to compress, and screw thread be exist loosen possible, therefore there is the possibility of loose contact in this wire clamp, and when being particularly arranged on the overhead transmission line that easily moved by wind, problem is even more serious.
Summary of the invention
Technical problem to be solved in the utility model, just be to provide a kind of for the penetrating cable clamp from power transmission line electricity taking, on the electric power transmission line that can be arranged on all size when not breaking cable insulation jacket and can from power taking cable, and structural design makes thimble can obtain a lasting pressure, thus ensure that the reliable contacts of thimble and cable conductor can not loosen, power taking contact is good.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
For the penetrating cable clamp from power transmission line electricity taking, it is characterized in that comprising:
One plastics C type fixed mount 2, c-shaped, an openend surface is provided with horizontal V-shaped groove, and have the stepped vertical hole and ladder transverse holes that are interconnected bottom V-shaped groove, another openend has the axial threaded hole pointing to V-shaped groove;
One plastics pressing handle 3 is bolt shape, is screwed in the axial threaded hole of described C type fixed mount one end;
One binding post 4, for the ladder square cylinder of conduction, detachably be arranged in the middle of stepped vertical hole bottom described C type fixed mount one openend V-shaped groove and ladder transverse holes, the large end of binding post has perpendicular screwed hole, small end has counterbore and can fix power taking electric wire by line pressing bolt and realize electrical connection;
One puncture handle 1, comprise a plastic housing, be the cylindrical shell with capping, have circular hole at the bottom of cylinder, cylinder bore is non-circular hole; One swivel nut b, for appearance car has the tubular structure having axial manhole in the middle of screw thread, afterbody is the sliding flat cylinder of joining plastic handle not rounded endoporus in cross section, and circular hole at the bottom of cylinder is passed in swivel nut front end from plastic housing; One thimble a is tip elongate cylinder, and afterbody is the sliding flat cylinder of joining plastic handle not rounded endoporus in cross section, and thimble exposes the needle point of certain length through the endoporus of swivel nut from plastic housing; One Compress Spring c, to be arranged in plastic housing between thimble rear end and capping;
Described puncture handle 1 pierces into from the large end in stepped vertical hole of C type fixed mount one end, and the appearance screw thread of swivel nut coordinates with binding post perpendicular screwed hole, and thimble passes C type fixed mount V-shaped groove.
Use procedure:
Use C type fixed mount and pressing handle to realize the fixing of wire clamp and cable, bottom V-arrangement stopper slot cable being placed in C type fixed mount, rotation pressing handle is until cable is compacted; C type fixed mount inside placed binding post, and binding post is connected with power taking electric wire, and has the screwed hole coordinated with the swivel nut of puncture handle.When the handle that punctures rotates because the effect whole handle of screw thread is to the precession of cable direction, retreat when screwing into thimble when thimble touches cable insulation sleeve, spring-compressed.Until the capping boss top in handle cannot retreat to thimble afterbody back center, be rotated further the insulating case that handle thimble penetrates cable and touch wire.
Beneficial effect: core of the present utility model is: be supplied to thimble pressure to cable conductor because spring is in compressive state after thimble contacts with cable conductor, ensure that the loose contact that can not cause thimble and wire because of the swing of cable.Because thimble, swivel nut and binding post are metalwork, namely the voltage of cable conductor be sent on power taking electric wire by these parts, and complete power supply by power taking electric wire access device .
Utilize the utility model can conveniently power taking from the cable with insulating case, fitting operation be easy, allows hot line job, long-play and still can the advantage of reliable contacts when cable flexing.Simultaneously little to cable fault, can by the contraction shutoff puncturing hole of the insulating case self of cable after removing power taking wire clamp.

Embodiment
As shown in Figure 2, of the present utility modelly to comprise for the penetrating cable clamp embodiment from power transmission line electricity taking:
One plastics C type fixed mount 2, c-shaped, an openend surface is provided with horizontal V-shaped groove, and have the stepped vertical hole and ladder transverse holes that are interconnected bottom V-shaped groove, another openend has the axial threaded hole pointing to V-shaped groove;
One plastics pressing handle 3 is bolt shape, is screwed in the axial threaded hole of described C type fixed mount one end;
One binding post 4, for the ladder square cylinder of conduction, detachably be arranged in the middle of stepped vertical hole bottom described C type fixed mount one openend V-shaped groove and ladder transverse holes, the large end of binding post has perpendicular screwed hole, small end has counterbore and can fix power taking electric wire by line pressing bolt and realize electrical connection;
One puncture handle 1, comprise a plastic housing, be the cylindrical shell with capping, have circular hole at the bottom of cylinder, cylinder bore is non-circular hole; One swivel nut b, for appearance car has the tubular structure having axial manhole in the middle of screw thread, afterbody is the sliding flat cylinder of joining plastic handle not rounded endoporus in cross section, and circular hole at the bottom of cylinder is passed in swivel nut front end from plastic housing; One thimble a is tip elongate cylinder, and afterbody is the sliding flat cylinder of joining plastic handle not rounded endoporus in cross section, and thimble exposes the needle point of certain length through the endoporus of swivel nut from plastic housing; One Compress Spring c, to be arranged in plastic housing between thimble rear end and capping;
Puncture handle 1 pierces into from the large end in stepped vertical hole of C type fixed mount one end, and the appearance screw thread of swivel nut coordinates with binding post perpendicular screwed hole, and thimble passes C type fixed mount V-shaped groove.
The on-circular cross-section of the present embodiment is the cylinder of flat, and cut two limits and become a kind of " kidney-shaped " shape, the inner hole of this shape and plastic handle d can prevent thimble a and swivel nut b from freely rotating, and namely when the handle 1 that punctures rotates, thimble a will rotate with swivel nut b together with handle.
Under free state, thimble a and swivel nut b is by spring c push-tight, if firmly press the needle point of thimble a, thimble a will retreat until encounter the boss of handle inner.
