Description
Technical field
The invention belongs to field of cable technology, particularly relate to a kind of cable enhancement mode drawing head.
Background technology
At present, along with all trades and professions are increasing to the demand of mechanics of communication, diameter and the weight of cable are also gradually increased,
Carrying the work that cable becomes the heaviest in work progress, therefore, people have invented the machinery of various carrying cable,
And the most general practice is that end separates core, then it is fixed by fixing device, then draws.
And the cable drawing head of original connection uses standard component lifting bolt to make pull rope, cable conductor is adopted and is screwed,
Owing to when screw is fixed, pressure area is limited, tenacity is largely restricted by standard component lifting bolt, and do so is also
Easily cause conductor to pull.Need to design a kind of new drawing head to solve described problem, as pull rope coupling part with
Drawing head main body uses Integral design, and conductor is connected by special conductor pressure pipe and tightly suppresses conductor, makes conductor can not pass through to be subject to
Power cover plate.Such design feature is that intensity is good, installs fairly simple, it is also possible to recycling.
Summary of the invention
The technical problem to be solved is to provide a kind of cable enhancement mode drawing head, is provided that bonding strength.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of cable enhancement mode drawing head, including traction
Head main body, stress cover plate, conductor pressure pipe, heat-shrinkable T bush, installing hole, suspension ring hole, described center, drawing head main body one end
Projection, high spot has a suspension ring hole, has outside an inner chamber, and the drawing head main body other end inside the drawing head main body other end
It is enclosed within one end of heat-shrinkable T bush, stress cover plate is installed in drawing head body lumen, stress cover plate uniformly has some installations
Hole, is inserted with conductor cable core in installing hole, conductor cable core stretches out the end of stress cover plate to be fixed with conductor pressure pipe, conductor pressure pipe
One end is disposed with one section of wall thickness thick section, and the described gap between stress cover plate, heat-shrinkable T bush and cable is filled with Colophonium,
The end face edge of described stress cover plate is disposed with a circle step, and described cable extend into inside step.
By screw thread, stress cover plate is installed in described drawing head body lumen.
It is coated with cable outside described conductor cable core, outside cable, is coated with the heat-shrinkable T bush other end.
Described installing hole has three, and installing hole is along radian distributions such as stress cover plate circumferences.
The diameter of described conductor pressure pipe is more than the diameter of installing hole.
Beneficial effect
Intensity of the present invention is good, installs simple, it is also possible to recycling.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, art technology
The present invention can be made various changes or modifications by personnel, and these equivalent form of values fall within the application appended claims equally and limited
Fixed scope.
Embodiment 1
As shown in Fig. 2～Fig. 5, a kind of cable enhancement mode drawing head, including drawing head main body 1, stress cover plate 2, conductor pressure
Pipe 3, heat-shrinkable T bush 4, installing hole 7, suspension ring hole 8, described drawing head main body 1 one end central protuberance, high spot has
, there is an inner chamber in one suspension ring hole 8, is cased with heat-shrinkable T bush outside drawing head main body 1 other end inside drawing head main body 1 other end
4 one end, in drawing head main body 1, intracavity is provided with stress cover plate 2, and stress cover plate 2 uniformly has some installing holes 7, peace
Dress is inserted with conductor cable core 6 in hole 7, and conductor cable core 6 stretches out stress cover plate 2 end to be fixed with conductor pressure pipe 3, conductor pressure pipe 3
One end be disposed with one section of wall thickness thick section, gap between described stress cover plate 2, heat-shrinkable T bush 4 and cable 5 is filled
Having Colophonium, the end face edge of described stress cover plate 2 to be disposed with a circle step, described cable 5 extend into inside step.
In described drawing head main body 1, intracavity is provided with stress cover plate 2 by screw thread.
Described conductor cable core 6 is outside is coated with cable 5, is coated with heat-shrinkable T bush 4 other end outside cable 5.
During use, cable conductor is stripped out enough length, after conductor cable core 6 passes the hole of stress cover plate 2, at conductor cable core
Overlap upper conductor pressure pipe 3 on 6, and with dedicated hydraulic pincers, conductor pressure pipe 3 is pressed on conductor cable core 6, be allowed to be tightly combined jail
Gu.Then drawing head main body 1 is spun on stress cover plate 2.Carry out encapsulation process again, complete drawing head and install.Cable applies
If time, cable pulling rope penetrates pull rope coupling part, i.e. suspension ring hole 8 being connected firmly, and pulling traction rope just can draw
Cable.
