Description

A kind of dismountable cable intermediate joint

Technical field

It the utility model is related to field of electrical equipment, more particularly to a kind of dismountable cable intermediate joint.

Background technology

When two power cables dock, the conductor of two cables needs with connecting tube pressure existing cable intermediate joint The mode connect connects, while, it is necessary to has this rubber parts of transition joint to encase insulating effect.When transition joint punch through damage When, maintenance procedure is：1 cuts open and peels off transition joint；2 sawed-off connecting tubes；3 one section of cable of excision；4 again stripping make cable； 5 medial heads are inserted in an end cable；6 crimping connecting tubes, make two cable conductor series windings；7 shift transition joint onto two cables Connecting portion

Therefore the rotten expense plenty of time with that must be destroyed during cable maintenance, is cut, circuit can not be fast in street corner among existing cable Quick-recovery is powered.

Utility model content

The technical problems to be solved in the utility model, it is to provide a kind of dismountable cable intermediate joint, solves existing Cable intermediate joint maintenance time length, the problem of not easy to install and consumptive material.

What the utility model was realized in：A kind of dismountable cable intermediate joint, including connecting tube, screw, bolt, The connecting tube is hollow cylinder, and inside also includes screw, the screw to place the cavity of cable on the connection tube wall The outside of UNICOM's cylinder and cavity, the screw is interior to be provided with screw thread, and the bolt is adapted with screw thread.

Further, the length of the bolt is more than the thickness of connection tube wall.

Further, the internal diameter of the connecting tube and the internal diameter of cable are equal.

Preferably, the outside aperture of the screw is more than medial aperture, and the outside aperture is more than the screw head diameter of bolt.

Specifically, the material of the connecting tube is metal.

Preferably, the quantity of the screw is four.

When employing the rubber parts breakdown of the utility model transition joint, it is not necessary to destroy connecting tube and cable, be also not required to Cable is remake, reduces maintenance cost, and greatly save the line maintenance time.

Embodiment

To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation Mode simultaneously coordinates accompanying drawing to be explained in detail.

Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of dismountable cable intermediate joint schematic diagram, including connecting tube 1, screw 2nd, bolt 3, the connecting tube are hollow cylinder, and to place the cavity of cable, described connect also includes screw on tube wall for inside, The outside of screw UNICOM cylinder and cavity, the screw is interior to be provided with screw thread, and the bolt 3 is adapted with screw thread.In Fig. 2 institutes In the specific embodiment shown, when outer insulation is breakdown, insulator, two economize on electricity cable conductor part insertion connections are cut open Guan Zhong, because common fastening means is compressed to cable intermediate joint, connecting tube deformation is set to reach the work for compressing cable With entirely connecting tube can only amputating and change when maintenance, in our embodiment, two economize on electricity cables are inserted in connecting tubes again It is connected, then bolt is inserted and screwed from screw, bolt abuts against cable and produces certain pressure to cable so as to tight Gu cable, bolt need to only be screwed out to come again when maintenance or dismounting, taken over without acute disconnection, reached dismountable The performance of cable intermediate joint, so as to save the material of cable intermediate joint, by such scheme, solve in the prior art Cable connector change waste time and energy, also waste of materials not energy-saving low-carbon the problem of.

In some further embodiments, the length of the bolt is more than the thickness of connection tube wall.In smoothly feelings Under condition, cable does not have a serious deformation, and the internal diameter of the connecting tube is equal with the internal diameter of cable.Therefore the length of bolt, which is equal to, connects The length of adapter wall can also abut against cable, it is necessary to which bolt length is more than the thickness of connection tube wall in the case of some other, So as to there is certain stroke redundancy, the cable deformed can be compressed, such scheme solves the fastening problems of the cable of deformation.

In other preferred embodiments, the outside aperture of the screw is more than medial aperture, and the outside aperture is big In the screw head diameter of bolt.Being arranged to outside by screw has certain size, for accommodating the screw head of locking so that outside bolt The height of dew is preferably hidden bolt, will not blocked when overcoat insulating barrier, by upper not over the outer wall of connecting tube Scheme is stated, has reached the effect for not influenceing rubber parts installation.

In specific embodiment, in order to improve service life of the present utility model, the material of the connecting tube is metal.

In some other preferred embodiment, in order to preferably fasten two economize on electricity cables, screw is on connection tube wall along even The bus distribution of adapter, in preferred embodiment, screw is along bus symmetric arrays, and as shown in Fig. 1, the quantity of screw is four, The left-right situs in figure.

Embodiment of the present utility model is the foregoing is only, not thereby limits scope of patent protection of the present utility model, Every equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or directly or indirectly fortune Used in other related technical areas, similarly it is included in scope of patent protection of the present utility model.
