The cold shrinkage forming device comprises a cloth bag and a clamp, wherein the cloth bag is arranged in the clamp. The cold shrinkage forming device for the cable connecting terminal, disclosed by the utility model, can conveniently mount the support strip in the elastic insulator, special tools are not required, and the mounting quality is further ensured. The device has the advantages of high cold shrinkage efficiency, simple structure, economy and practicality, and is suitable for large-range popularization.
Description
Technical field
The utility model relates to a kind of cable connecting terminal shaped device, relates in particular to a kind of shrinkage shaped device of cable connecting terminal.
Background technology
Cable connecting terminal collection waterproof, Stress Control, shield, electrically isolate from one, have good electric property and mechanical performance, can under various harsh environmental conditions, use for a long time.The cable connecting terminal has advantages such as in light weight, easy for installation.The cable connecting terminal is widely used in electric power, petrochemical industry, metallurgy, railway harbour and building every field.Existing cable connecting terminal comprises shrinkage cable termination and two kinds of structures of thermal contraction cable termination.
The shrinkage cable termination have volume little, easy to operate, rapid, need not specific purpose tool, the scope of application is wide and etc. advantage.Compare with the thermal contraction cable termination, the shrinkage cable termination need not used the fire heating.Because shrinkage cable termination head rest elastic compression power, the shrinkage cable termination moves after installing or the crooked hidden danger of quality of throwing off between the annex interior layer of can as the thermal contraction cable termination, not occurring, so range of application is very extensive.
The shrinkage cable termination is to utilize the elastic insulator material, and commonly used have silicon rubber and an ethylene-propylene rubber etc., in factory, injects sulfidization molding, constitutes the parts of various electric cable accessoriess again with the plastic spiral supporter through hole enlargement, lining.During on-the-spot the installation, these predilation spares are enclosed within after treatment cable end piece or joint, extract the plastic spiral bar (being support bar) of inner support out, elastic insulator is pressed on the cable insulation and the cable connecting terminal that constitutes.
But how elastic insulator closely is sleeved on spiral helicine support bar, is the key of shrinkage technology controlling and process always, also is the place that maximum hidden danger of quality occur.The utility model to the cable connecting terminal, provides a kind of shrinkage shaped device just, at utmost eliminates hidden danger of quality.
The utility model content
The utility model provides a kind of shrinkage shaped device of cable connecting terminal just to the deficiency of prior art existence.
For addressing the above problem, the technical scheme that the utility model is taked is following:
A kind of shrinkage shaped device of cable connecting terminal, it is inner to be used for that the support bar shrinkage is installed in the slightly little elastic insulator of internal diameter, and said shrinkage shaped device comprises cloth bag and anchor clamps, and cloth bag is arranged on the inside of anchor clamps.
Further, Installation Stress awl in advance in the said elastic insulator, and stress cone is installed in the side that support bar at first gets into elastic insulator.
The beneficial effect of the utility model is:
The shrinkage shaped device of the described cable connecting terminal of the utility model can be installed in elastic insulator inside with support bar easily, need not to use special tool(s), and has guaranteed installation quality.This device shrinkage efficient is high, simple in structure, economical and practical, suitable for large-scale promotion.
Description of drawings
Fig. 1 is the utility model embodiment one described cable connecting terminal installation forming structural representation;
Fig. 2 is the utility model embodiment two described cable connecting terminal installation forming structural representations.
Embodiment
To combine concrete embodiment that the content of the utility model is described below.
As shown in Figure 1, be the utility model embodiment one described cable connecting terminal installation forming structural representation.The shrinkage shaped device of the described cable connecting terminal of the utility model comprises cloth bag 3 and anchor clamps 4.Cloth bag 3 is arranged on the inside of anchor clamps 4.Elastic insulator 1 is a tubulose, and anchor clamps 4 can clamping elastic insulator 1.Elastic insulator 1 material is generally silicon rubber and ethylene-propylene rubber etc., therefore has certain elasticity.
According to the needs of cable connecting terminal, the external diameter of the support bar 2 of the described cable connecting terminal of the utility model is bigger slightly than the internal diameter of elastic insulator 1.In order support bar 2 to be installed in elastic insulator 1 inside, and compression closely.When using the described shrinkage shaped device of the utility model, at first elastic insulator 1 is clamped on the anchor clamps 4, and cloth bag 3 passes elastic insulator 1.In the cloth bag 3 at one end, spiral helicine support bar 2 is installed.At other end tension cloth bag 3, force cloth bag 3 along A to moving, like this support bar 2 under the drive of cloth bag 3, along B to moving.Like this, when mounted, as long as after being installed in support bar 2 in the elastic insulator 1 a little, can support bar 2 be installed in the elastic insulator 1 through the effect of cloth bag 3.Because the external diameter of support bar 2 is bigger slightly than the internal diameter of elastic insulator 1, therefore, 1 pair of support bar 2 of elastic insulator applies certain compressing force, has so just finally accomplished the moulding of cold-shrink type cable connecting terminal.
As shown in Figure 2, be the utility model embodiment two described cable connecting terminal installation forming structural representations.Embodiment two with the difference of embodiment one is; Installation Stress bores 5 in advance in elastic insulator 1; And stress cone 5 is installed in the side that support bar 2 at first gets into elastic insulator 1, and the shrinkage of so not only being convenient to support bar 2 is installed, and has shared the power that 2 pairs of elastic insulators 1 of support bar apply to a certain extent; Protect elastic insulator 1, improved the shrinkage installation quality.
Above content is the detailed description that combines concrete preferred implementation that the utility model is done, and can not assert that the utility model practical implementation only limits to these explanations.For the utility model person of ordinary skill in the field; Under the prerequisite that does not break away from the utility model design; Can also make some simple deduction or replace, all should be regarded as belonging to the utility model protection scope that the utility model is confirmed by claims of being submitted to.
Claims (2)
1. the shrinkage shaped device of a cable connecting terminal; Be used for support bar (2) shrinkage is installed in the slightly little elastic insulator of internal diameter (1) inside; It is characterized in that said shrinkage shaped device comprises cloth bag (3) and anchor clamps (4), cloth bag (3) is arranged on the inside of anchor clamps (4).
