Abstract
The invention discloses a kind of cold-contraction type indoor terminal.Terminal includes hollow insulation tube; hollow insulation tube one end inwall is embedded with stress cone; some full skirts are provided with outside the hollow insulation tube; also include protective case, the body that the protective case is made including elastomeric material, the body is parabola shaped; one end of the body is connected with support member; the other end is connected with spring, and the spring part is socketed on the support member, and the hollow insulation tube other end outside is provided with reinforcing ring.Cold-contraction type indoor terminal simple structure of the invention, by protective case is set so that insulation tube shrink when, slowly shunk, preferably can be close to cable, hermetically-sealed cable reduces the situation of cracking, improves the service life of terminal.
Description
Technical field
The present invention relates to a kind of cold-contraction type indoor terminal, belong to field of cable technology.
Background technology
Chilling shrink type cable accessory is injected in factory using elastomeric material (conventional has silicon rubber and EP rubbers)
Sulfidization molding, then through it is expanding, be lined with plastic spiral supporter composition, during in-site installation, by these predilation parts be enclosed within by
Extract the plastic spiral bar (supporter) of internal support, the elastomeric material pressure on top layer after cable end piece or joint after treatment out
Tightly in cable insulation.Because chilling shrink type cable accessory is at normal temperatures by elastic recovery force, rather than as thermal contraction cable accessory
Fiery heat shrink is used, therefore is commonly called as chilling shrink type cable accessory.
Existing chilling shrink type cable accessory is the stress support by internal support bar before being fitted without, and is in high-tension
In the state of, and because chilling shrink type cable accessory is predilation, may go out in the case where inner bracing strip is deposited for a long time
Stay is scattered or silica gel material fatigue shrinks situation not in place, therefore it cannot be guaranteed that has enough bullets after on cable
Property thrust, so that it cannot be guaranteed that good interfacial characteristics.In this case, more than cold-contraction type cannot be ensured after storage phase
The shrinkage stress of cable accessory, its elastic stress can be increased over time and gradually relaxed, therefore chilling shrink type cable accessory
The storage time limit it is shorter, generally half a year was to 2 years.In addition, existing chilling shrink type cable accessory uses solid silicone production performance
It is required that higher, the general cable shrinkage annex of quality is often cracking, shrink not tight phenomenon.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of cold-contraction type indoor terminal.
The present invention is achieved through the following technical solutions：
A kind of cold-contraction type indoor terminal, including hollow insulation tube, hollow insulation tube one end inwall are embedded with stress cone, it is described in
Some full skirts are provided with outside empty insulation tube, also including protective case, the body that the protective case is made including elastomeric material, described
Body is parabola shaped, and one end of the body is connected with support member, and the other end is connected with spring, and the spring part is socketed in
On the support member, the hollow insulation tube other end outside is provided with reinforcing ring.
A kind of described cold-contraction type indoor terminal, sets fluted on the inwall at the insulation tube two ends.
A kind of described cold-contraction type indoor terminal, the insulation tube includes straight length portion and curved section part, the umbrella
Skirt is located at straight length portion, and the stress cone is located at curved section part.
A kind of described cold-contraction type indoor terminal, the quantity of the full skirt is five.
A kind of described cold-contraction type indoor terminal, the full skirt is provided with protective cover with hollow insulation tube connecting place, described
Protective cover is circular arc.
A kind of described cold-contraction type indoor terminal, one end of the stress cone is arc.
The beneficial effect that the present invention is reached：
Cold-contraction type indoor terminal simple structure of the invention, by protective case is set so that insulation tube shrink when, be slowly to enter
What row shrank, preferably can be close to cable, hermetically-sealed cable reduces the situation of cracking, improves the service life of terminal.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：1st, insulation tube, 11, straight length portion, 12, curved section part, 2, stress cone, 3, full skirt, 4, protective case,
41st, body, 42, support member, 43, spring, 5, reinforcing ring, 6, groove, 7, protective cover.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated, a kind of cold-contraction type indoor terminal of the invention, including hollow insulation tube 1, the hollow insulation tube 1 one
End inwall is embedded with stress cone 2, and some full skirts 3 are provided with outside the hollow insulation tube 1, also including protective case 4, the protective case 4
Including the body 41 that elastomeric material is made, the body is parabola shaped, and one end of the body 41 is connected with support member 42, separately
One end is connected with spring 43, and the part of the spring 43 is socketed on the support member 42, outside the other end of hollow insulation tube 1
Side is provided with reinforcing ring 5.
Further, fluted 6 are set on the inwall at the two ends of the insulation tube 1, the air in extrusion groove 6 is formed
Negative pressure in groove 6, there is provided better seal performance.
Further, the insulation tube 1 includes straight length portion 11 and curved section part 12, and the full skirt 3 is located at straight
Line segment part 11, the stress cone 2 is located at curved section part 12.The quantity of the full skirt 3 is five.The one of the stress cone 2
It is arc to hold, and can effectively reduce stress concentration phenomenon so that Electric Field Distribution is also more uniform, such that it is able to improve the jail of connection
By property.
Further, the full skirt 3 is provided with protective cover 7 with the connecting place of hollow insulation tube 1, and the protective cover 7 is circle
Arc.Prevent from producing ponding in full skirt 3 and the junction of insulation tube 1 by protective cover 7, it is to avoid creepage phenomenon.
When in use, protective case 4 is placed in one end of insulation tube 1, cable to terminal of the invention（It is not shown）Into insulation tube 1
Afterwards, the device of supports insulative pipe 1 is taken out（It is not shown）, now, one end of the supports insulative pipe 1 of protective case 4, compression spring 43 is protected
Sheath 4 takes out from insulation tube 1, and insulation tube 1 shrinks, and hermetically-sealed cable, reinforcing ring 5 can improve the intensity of the end of insulation tube 1, long
Time is using can also keep preferable sealing.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these improve and deform
Also should be regarded as protection scope of the present invention.
