Description
Technical field
Technical field of cable connection is the utility model is related to, particularly a kind of three core shrinkage stress cast terminals.
Background technology
With taking place frequently for fire incident, people, which are recognized electric wire fire risk, constantly to deepen, and relevant department is to electricity
The requirement of the performances such as line fireproofing and block burn of cable also more and more higher.Because cable fire has, sprawling is fast, it is difficult to put out a fire to save life and property, produces secondary danger
Evil, the features such as recovery time is long, can bring huge loss to the lives and properties of national economy and the people.Therefore people couple
The fire performance of electric wire, security reliability propose harsher service condition.Such as fire prevention, explosion-proof, overload capacity is strong,
Service life is grown, and under Fire Conditions, Fire lift, fire pump need to keep the normal operation in certain time, and cable is burning
Low-smoke low-halogen low toxicity afterwards, or even the particular/special requirements such as smokeless halogen-free is nontoxic.Cable fire-proof measure is to reduce the weight that ignition of cable prolongs combustion
Means are wanted, key is being relied mainly on prevention, and all kinds of fire-resisting cables, fireproof cable are used widely.Conventional cold-shrink cable terminal
Poor heat resistance, meet high temperature and melt, service life is short.
Utility model content
The purpose of this utility model is to provide a kind of three core shrinkage stress tubes for above-mentioned the deficiencies in the prior art
Type terminal.
To achieve these goals, the core shrinkage stress cast terminal of one kind three designed by the utility model, its feature exist
In：Including binding post, seal pipe, cold-shrinkable terminal pipe and insulation tube, cold-shrinkable terminal pipe upper end is connect by seal pipe with described
Line terminals are connected, and cold-shrinkable terminal pipe lower end is connected with insulation tube, and stress cone is provided between cold-shrinkable terminal pipe and insulation tube, should
Power cone has abducent extension area, and extension area insertion cold-shrinkable terminal inside pipe wall, cold-shrinkable terminal pipe outer end is provided with by several
Umbrella annulus is arranged in order the umbrella skirt construction to be formed, and fingerstall is provided with below insulation tube, shielding earth is provided with cold-shrinkable terminal pipe, refers to
Set connects with insulation infratubal port sealing shroud.
It is preferred that umbrella skirt construction is made up of the isometrical umbrella annulus of some rows.
It is preferred that fingerstall has the accommodating chamber that current supply cable is placed, accommodating chamber is filled with filling glue-line.
It is preferred that cold-shrinkable terminal pipe upper and lower ends mouth is equipped with constant force spring.
It is preferred that it is enclosed with PVC tape between cold-shrinkable terminal pipe and seal pipe, between cold-shrinkable terminal pipe and insulation tube.
The core shrinkage stress cast terminal of one kind three that the utility model obtains, has advantages below：Play waterproof, moistureproof close
Envelope acts on.With excellent resistance to weather, acid-proof alkaline, reach the effect for sealing of sharing a common fate, be communication cable, coaxial cable,
The desirable seal product of medium-low voltage power cable.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
The utility model is further illustrated with reference to embodiment and accompanying drawing.
Embodiment：
As shown in figure 1, the core shrinkage stress cast terminal of one kind three that the present embodiment provides, including binding post 1, sealing
Pipe 2, cold-shrinkable terminal pipe 3 and insulation tube 4, the upper end of cold-shrinkable terminal pipe 3 are connected by seal pipe 2 with the binding post 1, shrinkage
The lower end of terminal conduit 3 is connected with insulation tube 4, and stress cone 7 is provided between cold-shrinkable terminal pipe and insulation tube, stress cone 7 have to
The extension area 8 of external expansion, extension area insertion cold-shrinkable terminal inside pipe wall, cold-shrinkable terminal pipe outer end is provided with by several umbrella annulus 9
The umbrella skirt construction to be formed is arranged in order, is mainly set from lower to upper successively along cold-shrinkable terminal pipe, the lower section of insulation tube 4, which is provided with, to be referred to
Set 5, cold-shrinkable terminal pipe 3 is interior to be provided with shielding earth, and fingerstall 5 is socketed with the sealing of the lower port of insulation tube 4.
Umbrella skirt construction is made up of the isometrical umbrella annulus of some rows, greatly improves external insulation electric property.
In order to preferably reinforce and improve product reliability, fingerstall has the accommodating chamber that current supply cable is placed, and accommodating chamber is filled out
Filled with filling glue-line 6.
Cold-shrinkable terminal pipe upper and lower ends mouth is equipped with constant force spring, and constant force spring significantly more efficient can connect to cable 10
To reliability.
PVC tape is enclosed between cold-shrinkable terminal pipe and seal pipe, between cold-shrinkable terminal pipe and insulation tube.
It is described further for the design：Wherein cast terminal employs liquid rubber material manufacture and formed, and not only has
There is excellent electric property, and there is the things such as the long and constant systolic pressure of excellent hydrophobicity, high resiliency, service life
Manage characteristic.
Stress Control part is using stress wimble structure and prefabricated integral with major insulation, efficiently solves cable external shield
Electric stress concentration problem at face, it is ensured that insulation is reliable, safe for operation.
For the utility model person of an ordinary skill in the technical field, the utility model design is not being departed from
Under the premise of, its framework form can be flexible and changeable, simply makes some simple deduction or replace, should all be considered as belonging to by this reality
The scope of patent protection determined with new submitted claims.
