Abstract
The utility model discloses a novel big cross -section strain insulator anchor clamps for wire, including steel anchor, strain insulator aluminum pipe and aluminium bushing pipe, in the strain insulator aluminum pipe was located to crimping pipe I in being provided with in the strain insulator aluminum pipe, aluminium bushing pipe cover, screw thread fixed connection was passed through on the steel anchor in the top of interior crimping pipe I. The utility model discloses a form of layering crimping has that strain insulator reinforce, wire atress are even, the wire is difficult for advantages such as impaired.
Description
Technical field
The utility model is related to a kind of new large-section lead strain insulator fixture, belongs to power cable tools technical field.
Background technology
With the fast development of power industry, Great span, large-section lead use also more and more extensive.But for such
In the case of strain insulator fixture be difficult to meet the requirement of tension force.For this reason, it may be necessary to a kind of new technical scheme is asked solving above-mentioned technology
Topic.
Utility model content
The purpose of this utility model is to provide that a kind of point of three laminations connect, tension is strong, wire uniform force, wire are difficult to receive
The Great span and large-section lead strain insulator fixture of damage.
The technical solution adopted in the utility model is：
A kind of new large-section lead strain insulator fixture, including steel anchor, strain insulator aluminum pipe and aluminium bushing pipe, in the strain insulator aluminum pipe
Interior aluminium hydraulic pressed connecting pipe I is provided with, in strain insulator aluminum pipe, the top of the interior aluminium hydraulic pressed connecting pipe I is threadably secured company to the aluminium liner sleeve
It is connected on steel anchor.
Further, also including interior aluminium hydraulic pressed connecting pipe II, the top of the interior aluminium hydraulic pressed connecting pipe II is provided with crimping notch, the internal pressure
Adapter II is crimped in interior aluminium hydraulic pressed connecting pipe I.
The utility model is in the form of layering crimping, while using two interior aluminium hydraulic pressed connecting pipes, interior aluminium hydraulic pressed connecting pipe I adopts screw thread shape
Formula and steel anchor inner tube connect, by the connecting length for adjusting screw thread, to solve ectonexine steel core due to crimping material and technique
The inconsistent problem of the inside and outside elongation percentage that brings, and then prevent due to discontinuity equalization and cause one layer to extend excessive without complete
The generation of situations such as stress is so as to rupture.
The utility model is additionally provided with interior aluminium hydraulic pressed connecting pipe II in interior aluminium hydraulic pressed connecting pipe I, i.e., by the way of three layers of layering crimping.
During crimping, a part of steel core of wire is crimped in interior aluminium hydraulic pressed connecting pipe II first, then interior aluminium hydraulic pressed connecting pipe II is crimped on into aluminium hydraulic pressed connecting pipe I
It is interior, then part steel core is crimped in aluminium hydraulic pressed connecting pipe I again, and aluminium hydraulic pressed connecting pipe I is crimped on by way of screw thread and crimping combine
In steel anchor, finally remaining steel core is crimped in steel anchor again, has been achieved in that the purpose that three laminations of steel core point connect so that steel core
Uniform force, substantially increases strain insulator force value.At the same time, aluminium bushing pipe is provided with strain insulator aluminum pipe, in the aluminium of crimping lead wire
During layer, the aluminium lamination of wire is placed on in aluminium bushing pipe crimping simultaneously, so can effectively reduce compression ratio, it is ensured that subtract during crimping
Few damage to wire aluminium lamination, while the reduction of compression ratio can make wire and steel core stress and respective its maximum of performance is excellent simultaneously
Gesture, reaches optimal strain insulator effect.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Wherein：1st, steel anchor, 2, aluminium hydraulic pressed connecting pipe II, 3, aluminium hydraulic pressed connecting pipe I, 4, strain insulator aluminum pipe, 5, aluminium bushing pipe, 6, crimping notch.
Specific embodiment
As shown in figure 1, a kind of new large-section lead strain insulator fixture, including steel anchor 1, strain insulator aluminum pipe 4 and aluminium bushing pipe 5,
Interior aluminium hydraulic pressed connecting pipe I 3 is provided with strain insulator aluminum pipe 4, aluminium hydraulic pressed connecting pipe II 2 is crimped with aluminium hydraulic pressed connecting pipe I 3, at the top of interior aluminium hydraulic pressed connecting pipe II 2
The crimping notch 6 for crimping is provided with, aluminium bushing pipe 5 is sheathed in strain insulator aluminum pipe 4, the top of interior aluminium hydraulic pressed connecting pipe I 3 is solid by screw thread
Surely it is connected on steel anchor 1.
