Tension conductor cable strain clamp
Technical field:
The present invention relates to the electric armour clamp of tension conductor cable connection, specially a kind of tension conductor cable strain clamps.
Background technique:
Strain clamp is for fixing tension conductor cable, is a kind of to lead tension to bear the tension of tension conductor cable
Electric wire cable is hung to the electric armour clamp in strain insulator-string group or shaft tower.
(grip of clamp is not less than tension conductor wire to a type of strain clamp in addition to the whole pulling force for bearing conductor cable
The 95% of the specified tensile strength of cable), also using as electric conductor, therefore this kind of wire clamp is Yi Dan installed, cannot go disassembly again,
Also known as dead wire presss from both sides.
The generation type of the dead wire folder is that the outer circle many places of contact tube are pinched using hydraulic tongs, by the deformation of contact tube
And the lead cable and steel grip of contact tube and its inside are tightly become into an entirety.
But in the high altitude operation of actual installation, it is very inconvenient to carry hydraulic tongs, and operate hydraulic tongs to spend great strength,
Need more people's cooperations that could complete.
Summary of the invention:
In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to propose, a kind of contact area is big, connects
Connect secured and easily operated tension conductor cable strain clamp.
It is able to solve the tension conductor cable strain clamp of above-mentioned technical problem, technical solution includes connector, and institute is not
Same is that the connector includes that conductive taper shrinks set and conductive connection pipe and steel anchor, and the conduction taper contraction is put on out
Equipped with axial shrinkage slot, the front middle part of the conductive connection pipe is straight and rear portion is bent, and conductive connection pipe front end is combined with locking
Swivel nut offers the through-hole coaxial with front middle part tube body on the tube body of conductive connection pipe bending place;Former and later two conductive tapers are received
For contracting set respectively with being located at the front end nozzle of front middle part tube body and in the nozzle of rear end, former and later two conductive tapers shrink set
Small conehead is relatively and a conductive taper is shunk the small conehead covered and is placed in the small conehead of another conductive taper contraction set, leading
Electric taper shrinks the big conehead of set in the running-on closed end for being butted on locking swivel nut outside the nozzle of front end, and rear conduction taper shrinks the big of set
Conehead is butted on the upper and lower limits screw screwed on conductive connection pipe backward;Steel anchor of the front end with position-limiting tube is from conductive connection pipe
Through-hole put in forward and backward conductive taper forward and shrink in set, axially spaced-apart is equipped with bulge loop on the steel anchor;The locking swivel nut
Running-on closed end offers the perforating for allowing tensile cord cable core to enter, and the steel core of tensile cord cable core, which is worn, is located in position-limiting tube
Interior, the loose the end of a thread of tensile cord cable core wraps at least two bulge loops on steel anchor, and the end of a thread between adjacent bulge loop is clamped down on
Tool holder is on steel anchor.
Conventionally, the big conical head end thickness that the conductive taper shrinks set is greater than or equal to conelet head end thickness.
Beneficial effects of the present invention:
1, the connection type that tension conductor cable strain clamp of the present invention is covered using the contraction of jam-packed conduction taper is suppressed, two
The conductive taper of mutual jam-packed shrinks set and is finally shaped to an approximate cylindrical body, in package clamping line head in the same of steel anchor bulge loop
When also increase and the contact area of conductive connection pipe (reduce resistance, high current be connected), therefore the resistance to bracing cable of the structure
Folder is connected firmly and is easily installed, and electric conductivity is enhanced, and is conducive to remote safe transmission electric energy.
2, the configuration of the present invention is simple is easy to make, quick for installation, is connected firmly and (is deformed by elastic physical property), anti-to jolt
It loosens, anti-lightning strike, insulation arc is anti-discharge on fire, and failure of shutting out, the long-life saves the energy.

Specific embodiment:
Technical solution of the present invention is described further with reference to the accompanying drawing:
Tension conductor cable strain clamp (connection for tensile cord cable core 8) of the present invention includes connector, the company
Fitting includes that conductive taper shrinks 1 (offering axial shrinkage slot 1-1's thereon) of set, conductive connection pipe 2 and steel anchor 4, described to lead
The big conical head end thickness that electric taper shrinks set 1 is greater than conelet head end thickness, 2 front middle part of conductive connection pipe is straight and rear portion to
Upper bending (bending part connects conduction wire clamp 7 with screw), the front end sleeve Hole chamfering of conductive connection pipe 2 become groove, and conduction connects
It is combined with locking swivel nut 3 on 2 front end of spool, is offered on the tube body of 2 bending place of conductive connection pipe coaxial with front middle part tube body
Through-hole 9 is combined with upper and lower limits screw 6 on the forward tube body of through-hole 9;It is coaxial respectively that former and later two conductive tapers shrink set 1
At the front end nozzle of front middle part tube body and in the nozzle of rear end, former and later two conductive tapers shrink set 1 small conehead it is opposite and
The small conehead that preceding conduction taper shrinks set 1 is placed in rear conductive taper and shrinks in the small conehead of set 1, and preceding conduction taper shrinks set 1
