Description
Technical field
The utility model relates to wire and cable field, in particular to a kind of wire and cable of mine car electric transmission.
Background technique
The wire and cable of mine car electric transmission, when in use, since the cable of dragging is longer, cable can connect with ground
Touching, and mechanical equipment friction of motion on the ground is followed, cause serving and ground friction impaired, therefore such cable or electricity
Line service life is often shorter.
In addition, the structure of cable or electric wire is often fairly simple, at work, a large amount of heat can be generated, these hot meetings
Cause cable or cable service performance to reduce, influences its service performance, therefore the heat dissipation performance for promoting cable is highly desirable.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of wire and cables of mine car electric transmission, can effectively prevent
Serving is worn, and can increase whole heat dissipation performance again, effectively solves deficiency in the prior art.
The utility model is achieved through the following technical solutions: a kind of wire and cable of mine car electric transmission, including electricity
Cable serving is provided with an installation cavity among cable serving, is packed into a core wire, the protective layer outer wall one of core wire in installation cavity
The more than one fixed hub of body injection molding, the outboard end of fixed hub open up an axis hole, are packed into one in axis hole
Spring is supportted, the one buffering axle sleeve of external suit of support spring, the inner end of the buffering axle sleeve opens up a spring eye, supports bullet
It is incorporated in spring eye at the top of spring, an air-breathing sponge is filled in the inside of spring eye, and one end of the support spring is inserted into
Contact support in spring eye and with the bottom surface of air-breathing sponge, support spring postpones buffering axle sleeve punching ejection, the cushion hole
It is provided on cable serving.
The internal diameter of the cushion hole is greater than the outer diameter of buffering axle sleeve as a preferred technical solution,.
The external extension end of the buffering axle sleeve is a spherical as a preferred technical solution,.
The inner end of the buffering axle sleeve is provided with two limit baffles as a preferred technical solution, limits baffle one
End is contacted with cable serving inner wall, and the limit baffle is with respect to equal one guide rod of vertical welding in cable serving one end, face
A pilot hole is opened up on the cable serving of every guide rod, guide rod is inserted in pilot hole.
The air-breathing sponge is memory foam as a preferred technical solution,.
The beneficial effects of the utility model are: the utility model structure is simple, can effectively prevent making because of pulling outer
The situation of tegillum breakage increases the service life of wire and cable, and utilizes built-in air-breathing sponge, when buffering axle sleeve compression,
Hot-air in air-breathing sponge can be squeezed out to outside, reach good heat dissipation effect.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including cable serving 3, it is provided with an installation cavity 12 among cable serving 3, installed
A core wire 1, the more than one fixed hub 11 of protective layer outer wall integrated injection molding of core wire 1, fixed hub are packed into chamber 12
11 outboard end opens up an axis hole, and a support spring 7 is packed into axis hole, and the external of support spring 7 is set with a buffer shaft
Set 2, buffering axle sleeve 2 inner end open up a spring eye, the top of support spring 7 is incorporated in spring eye, spring eye it is interior
An air-breathing sponge 5 is filled in portion, and one end of support spring 7 is inserted into spring eye and contacts support with the bottom surface of air-breathing sponge 5,
Support spring 7 will buffer axle sleeve 2 and eject from cushion hole 8, and cushion hole 8 is provided on cable serving 3.
In the present embodiment, the internal diameter of cushion hole 8 is greater than the outer diameter of buffering axle sleeve, and the inner end of buffering axle sleeve 2 is provided with
Two limit baffles 13, limit 13 one end of baffle are contacted with 3 inner wall of cable serving, and limit baffle 13 is with respect to cable serving 3 one
Equal one guide rod 4 of vertical welding is held, opens up a pilot hole 6, guide rod 4 on the cable serving of every guide rod of face 4
It is inserted in pilot hole 6, when buffering axle sleeve is after compression, limit baffle no longer reseals cushion hole, therefore in the present embodiment,
Limit baffle allows for covering cushion hole and seals, and after limit baffle is opened, that is, may make internal hot-air energy
It is enough to be discharged from cushion hole, realize heat dissipation.
Wherein, the external extension end for buffering axle sleeve 2 is a spherical, and spherical can be effective when with externally face contact
Contact, so that serving will not be directly with ground face contact, when buffering axle sleeve compression, support spring is compression, is now placed in
Memory foam in spring eye can be compressed, and compressive state typically occur in limit baffle separated with cushion hole after, at this time
Cushion hole is conducting, and the hot-air squeezed out at this time can be discharged from cushion hole at once, and after support spring reset, it can
So that memory foam sucks the hot-air inside serving again, extruding next time is waited.
The beneficial effects of the utility model are: the utility model structure is simple, can effectively prevent making because of pulling outer
The situation of tegillum breakage increases the service life of wire and cable, and utilizes built-in air-breathing sponge, when buffering axle sleeve compression,
Hot-air in air-breathing sponge can be squeezed out to outside, reach good heat dissipation effect.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
