Description
Technical field
The utility model relates to the technical fields of electric wire conduit, are a kind of insulating sheaths of low tension cable end.
Background technique
End is the connecting pin of cable and electrical equipment, and when cable dispatches from the factory, both ends are all sealings, but actual
In laying or connection procedure, end will all be splitted, this just destroys its original sealed insulation, if long-term exposure
End in external environment is influenced by adverse circumstances such as wind and rain ice and snow or dragging of drilling team during removal of home,
Biggish external force can be brought to damage to end, cause the insulated hull season cracking of end and lost between copper core viscous
Property, cause anti-insulating properties, the waterproof performance of end seriously to reduce.
Summary of the invention
The utility model provides a kind of insulating sheath of low tension cable end, overcomes the defects of the prior art,
Cable after can effectively solve factory is in use due to destroying its original sealed insulation, in outside environmental elements
Under the influence of, it is be easy to cause the problem of anti-insulating properties of end is with waterproofness reduction, and can further solve drilling team's removal of home
The problem of causing external force to damage end.
The technical solution of the utility model is realized by following measures: a kind of insulating sheath packet of low tension cable end
It includes
Sheath ontology, sheath ontology are connected with sealing sheath ontology upper port in a tubular form, in the upper end of sheath ontology
Diaphragm seal, be at least connected with two mutually independent bifurcated short tubes on the upper surface of diaphragm seal, each bifurcated short tube
Lower end is all connected to the inside of sheath ontology, is set with a core sleeve, sheath ontology in the outside of each bifurcated short tube
All it is cold shrink tube with bifurcated short tube, the first spiral support item of predilation sheath ontology internal diameter is provided in sheath ontology, often
The second spiral support item of predilation bifurcated minor tube inner diameter is both provided in a bifurcated short tube, core sleeve is the pyrocondensation of insulation
Pipe.
The utility model reasonable and compact in structure can be to end and electricity by setting sheath ontology and core casing
Core inside cable forms tight, avoids phase fault phenomenon, effectively enhances the anti-insulating properties and waterproof of end
Property, the sheath is quality, wearability is high, can effectively prevent drilling team's removal of home damage of the external force caused by end.
Detailed description of the invention
Attached drawing 1 is schematic diagram of main cross-sectional structure of the best embodiment of the utility model.
Attached drawing 2 is the A of structure shown in attached drawing 1 to schematic cross-sectional view.
Coding in attached drawing is respectively as follows: 1 for sheath ontology, and 2 be diaphragm seal, and 3 be bifurcated short tube, and 4 be core sleeve, and 5 are
First spiral support item, 6 be the second spiral support item.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: the positional relationship of upper and lower, left and right is the Butut according to Figure of description 1
Direction determines.
The utility model is further described below with reference to examples and drawings:
As shown in attached drawing 1,2, the insulating sheath of the low tension cable end includes sheath ontology 1, sheath ontology 1 in a tubular form,
The upper end of sheath ontology 1 is connected with the diaphragm seal 2 of 1 upper port of sealing sheath ontology, at least one on the upper surface of diaphragm seal 2
There are two mutually independent bifurcated short tube 3, the lower end of each bifurcated short tube 3 is connected to the inside of sheath ontology 1 for body connection,
The outside of each bifurcated short tube 3 is set with a core sleeve 4, and sheath ontology 1 and bifurcated short tube 3 are all cold shrink tube, is protecting
It is provided with the first spiral support item 5 of 1 internal diameter of predilation sheath ontology in set ontology 1, is both provided in each bifurcated short tube 3 pre-
The second spiral support item 6 of 3 internal diameter of bifurcated short tube is expanded, core sleeve 4 is the heat-shrink tube of insulation.
The utility model primarily directed to be low-voltage cable insulated wire, the main function of sheath ontology 1 is covered in cable
On head, seal protection is formed to end, sheath ontology 1 and bifurcated short tube 3 are all cold shrink tube, and material is liquid silastic,
It has good insulating properties, resistance to electric trace, high temperature resistant and resistance to acid and alkali, and has high resiliency and self-constriction, therefore can
There is provided constant lasting radial pressure to end and core, in use will not because of cable bending and to form insulation dead
The setting of angle, the first spiral support item 5 and the second spiral support item 6 can respectively to sheath ontology 1, bifurcated short tube 3 internal diameter
Predilation is formed, is can be convenient by sheath ontology 1,3 sets of bifurcated short tube on end and core in this way, after suit, only
First spiral support item 5 and the second spiral support item 6 need to be extracted out, package effect, the first spiral support article 5 and can be realized
Two spiral support items 6 are conventionally known technology, and straight line, the height of liquid silastic can be gradually become during pull
Elasticity can adapt to the cable of different-diameter, improve the use scope of the utility model, by 1 set of sheath ontology in end
It goes forward, it is also necessary to be filled up its gap using insulation material of filling a vacancy in the crotch of end core, so that sheath ontology 1 is being received
Reach certain compactness and cementability after contracting between the appearance of the section, the main function of bifurcated short tube 3 is in cable
The core in portion is split, and bifurcated short tube 3 is generally four, and the core sleeve 4 for being sleeved on 3 outside of bifurcated short tube then can be right
Four exposed cores form individual seal protection, since core casing is heat-shrink tube, have insulation, ageing-resistant excellent spy
Property, it is at room temperature in glassy state, after being heated, heat-shrink tube will become elastomeric state, be wraps closely about the outside of core, this reality
After novel install, good compactness and cementability can be reached between sheath ontology 1 and end so that end with
Gap between sheath ontology 1, between core sleeve 4 and core is very little, being capable of the weak electricity of effectively pre- rainwater-proof intrusion
Inside cable end, so as to avoid phase fault phenomenon, the anti-insulating properties and waterproofness of end, the sheath quality are effectively enhanced
It is excellent, wearability is high, can effectively prevent drilling team removal of home the external force caused by end damage.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
