Description
Technical field
The utility model is related to a kind of cable accessory, and in particular to one kind is applied to power cable terminal or middle connection
Elastic heat-shrink cable accessory.
Background technology
When cable is run, when current capacity is excessive, causes the core inside cable to generate heat, make cable insulation and pyrocondensation
The temperature of insulation tube is inconsistent so that cable insulation expanded by heating is larger, and pyrocondensation insulation tube thermal expansion is small so that pyrocondensation is insulated
Pipe produces permanent mechanical expansion.When cable current load becomes it is small when, cable insulation retraction, because of pyrocondensation insulation tube at normal temperatures not
Shrink, cause to produce gap between cable and heat-shrink cable accessory, cause cable local discharge excessive, especially in the cable between
Connection and terminal connect stress concentration controlling position, long-play for a period of time after, be easily caused cable upper stress collection
In position it is breakdown.
Utility model content
The purpose of this utility model is to provide a kind of elasticity for avoiding producing gap between cable and heat-shrink cable accessory
Heat-shrink cable accessory.
To achieve these goals, the technical solution adopted in the utility model is：
A deformation tube is set in a kind of heat-shrink cable accessory, including pyrocondensation insulation tube body, the pyrocondensation insulation tube body
Body, the deformation body is taper thick between the detail of two ends, and deformation body is made up of elastomeric material, the deformation tube internal body portion
It is furnished with multiple hollow deformation chambers, the inwall of one end of the deformation body and is embedded with plastics reed pipe, the one of the plastics reed pipe
Side is set in a fluting, deformation tube body and is embedded a ring-shaped clip, and ring-shaped clip correspondence plastics reed pipe is set.
By using above-mentioned technical proposal, a deformation body that can be deformed upon is set in pyrocondensation insulation tube body, when
During the deformation that cable insulation expands with heat and contract with cold, recoverable deformation can also occur accordingly for deformation tube body, it is to avoid cable with
The possibility in gap is produced between heat-shrink cable accessory, and sets deformation chamber, plastics reed pipe, ring-shaped clip that there is deformation body
Good elastic restoring force and stable clamping force.Wherein, the elastic force for being provided for enhancing deformation body itself of deformation chamber；
Plastics reed pipe is not susceptible to deformation as middleware, reduces the generation in gap；Ring-shaped clip is used to strengthen tightening for deformation body
Power.
The utility model is further arranged to, and some through holes are distributed with the tube wall of the plastics reed pipe.By using
The technical scheme, for the elastic deformation power of reinforced plastics reed pipe,.
The utility model is further arranged to, and the plastics reed pipe is that one end is big, the small taper of the other end.
The utility model is further arranged to, and the larger end of the ring-shaped clip and plastics reed pipe is correspondingly arranged.
The utility model is further arranged to, and the ring-shaped clip is tool becket jaggy.
The utility model is further arranged to, and the deformation chamber is set close to the larger end of plastics reed pipe.
By using above-mentioned technical proposal, plastics reed pipe, ring-shaped clip, deformation chamber all concentrated settings in deformation body
One end, making one end of deformation body has stronger elastic deformation ability and binding force, and other end elastic deformation ability and beam
Clamp force is relatively poor, so that the stress at deformation body two ends can have differences, the other end therein can share ring-shaped clip institute
Power at end, the service life for extending deformation body.
Brief description of the drawings

Fig. 2 is the structural representation of the utility model plastics reed pipe；
Fig. 3 is the structural representation of the utility model ring-shaped clip.
Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
The utility model is illustrated below with reference to Fig. 1 to Fig. 3.
A deformation is set in a kind of heat-shrink cable accessory, including pyrocondensation insulation tube body 1, the pyrocondensation insulation tube body 1
Body 2, the deformation body 2 is taper thick between the detail of two ends, and deformation body 2 is made up of elastomeric material, the deformation body 2
Inside is distributed with multiple hollow deformation chambers 3, the inwall of one end of the deformation body 2 and is embedded with plastics reed pipe 4, deformation tube
Groove of the body 2 provided with placement plastics reed pipe 4, the side of the plastics reed pipe 4, which is set, is embedded an annular in a fluting 5, deformation body 2
Clip 6, the corresponding plastics reed pipe 4 of the ring-shaped clip 6 is set.
By using above-mentioned technical proposal, being insulated in pyrocondensation, tube body 1 is interior to set a deformation body 2 that can be deformed upon,
When the deformation that cable insulation expands with heat and contract with cold, accordingly recoverable deformation can also occur for deformation body 2, it is to avoid cable
The possibility in gap is produced between heat-shrink cable accessory, and sets deformation chamber 3, plastics reed pipe 4, ring-shaped clip 6 to make deformation tube
Body 2 has good elastic restoring force and stable clamping force.Wherein, deformation chamber 3 is provided for enhancing deformation body 2 itself
Elastic force；Plastics reed pipe 4 is not susceptible to deformation as middleware, reduces the generation in gap；Ring-shaped clip 6 is used to strengthen shape
Become the binding force of body 2.
Some through holes 7 are distributed with the tube wall of plastics reed pipe 4.By using the technical scheme, for reinforced plastics reed pipe 4
Elastic deformation power.
Plastics reed pipe 4 is that one end is big, and the small taper of the other end, the ring-shaped clip 6 is corresponding with the larger end of plastics reed pipe 4
Set, the ring-shaped clip 6 is the becket with breach 8, the deformation chamber 3 is set close to the larger end of plastics reed pipe 4.
By using above-mentioned technical proposal, plastics reed pipe 4, ring-shaped clip 6, all concentrated settings of deformation chamber 3 in deformation tube
One end of body 2, making one end of deformation body 2 has stronger elastic deformation ability and binding force, and other end elastic energy of deformation
