Abstract
The utility model relates to a cable transition joint, comprising a cable core joining terminal. The utility model is characterized in that the cable core joining terminal is arranged in the transition joint body; a plug is inserted in the cable core joining terminal; the plug is tightly fitted with the transition joint body. Due to the adoption of the removable transition joint for line test, damage to the transition joint caused by repair of 35 kv power cable of light railway, subway and smelting plant after operation for long time is reduced; repair time is saved; various potential safety hazards during repair carried out by the repair personnel can be avoided; defects in the prior art is overcome. The utility model has the advantages of reasonable structure, convenient assembly and disassembly, and safe and reliable use.
Description
Technical field
The utility model relates to a kind of cable connecting arrangement, relates in particular to a kind of transition joint structure of using between cable.
Background technology
At present, domestic and international comparatively advanced transition joint has all just recovered the structure of cable itself.But when install in the line shrinkage or after pyrocondensation transition joint operation a period of time, as need circuit is carried out maintenance, then need to take shrinkage apart or the pyrocondensation transition joint destroys true insulation system.After test is finished, need reinstall new transition joint or annex.
Above-described repair method to cable, need when line maintenance, destroy transition joint or other annex, not only increased cost, also wasted the more repair time, in addition, the maintainer also exists multiple potential safety hazard in maintenance process, therefore, existing this cable transition joint project organization is unreasonable, very inconvenience of installing/dismounting, dangerous, reliably poor in the use.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cable joint, and this cable joint is rational in infrastructure, safe ready during line maintenance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cable intermediate joint, comprise the core splicing ear, this core splicing ear is placed in the transition joint body, corresponding to described core splicing ear place, on described transition joint body, offer the plug holding part, be plugged with plug in this plug holding part, be plugged with plug, this plug and described transition joint body closely cooperate.
The main header casing of described plug is provided with screening cover.
Described core splicing ear is electrically connected by a stud.
Described cable intermediate joint is settled the inside of metal shell, and this metal shell is fixed on the cable bearer.
Also include earth connection, this earth connection is placed on the cable steel armour, and is fixed by constant force spring.
Described transition joint body, constant force spring, and the lateral wall of cable on be coated with heat-shrink tube.
The measuring head that described plug holding part can be ccontaining can be tested cable line.
The beneficial effects of the utility model are: because demountable structure of the present utility model, destroy transition joint or other annex when having reduced the conducting transmission line maintenance, maintenance and recovery power transmission and distribution time have been saved widely, reduced user's production cost, and the multiple potential safety hazard of having avoided the maintainer in maintenance process, to occur, the utility model has remedied the deficiencies in the prior art, make product have project organization rationally, easy installation and removal, characteristics such as safe in utilization, reliable.
Description of drawings
Fig. 1 is the structural representation of a kind of cable intermediate joint of the utility model;
Fig. 2 is a kind of cable intermediate joint of the utility model structural representation in tested when maintenance;
Fig. 3 is that a kind of cable intermediate joint of the utility model is installed on the structural representation in the circuit.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of a kind of cable intermediate joint of the utility model.In metal shell 30, a core splicing ear 102 is extended at the end place of two cables 10 respectively, and this core splicing ear 102 is placed in the transition joint body 302.These two core splicing ears 102 connect by a stud 104, as utilize specification to connect for the stud of M12 carries out the screw thread rotation formula.Earth connection 70 is placed in respectively on the cable steel armour at two ends, and is held the fixing of formula by constant force spring 60 respectively.Described transition joint body 302, constant force spring 60, and the lateral wall of cable 10 on be coated with heat-shrink tube 80, in order to play the effect of insulation and protection.Corresponding to described stud 104, on described transition joint body 302, offer plug holding part 304 respectively, be mounted with plug 40 respectively in this plug holding part 304, this plug 40 can closely cooperate with described transition joint body 302.The top of plug 40 is covered with screening cover 50 respectively.Described transition joint body 302 can adopt the materials such as ethylene propylene diene rubber as excellent electrical properties.Described plug 40 can adopt the materials such as epoxy resin as excellent electrical properties.
Please refer to shown in Figure 2ly, Fig. 2 is a kind of cable intermediate joint of the utility model structural representation in tested when maintenance.When needs are tested, the screening cover 50 and the plug 40 of one end are pulled down respectively, the measuring head of Hi-pot test rod 90 is stretched in the plug holding part 304, and test is connected with core splicing ear 102 places of exposing with high pressure gets final product, finish, pull down Hi-pot test rod 90 when test, plug 40 is installed again, at last, cover screening cover 50, can recover line powering.
Please refer to shown in Figure 3ly, Fig. 3 is installed on structural representation in the pathway for a kind of cable intermediate joint of the utility model.Cable fixed mount 20 is used for fixing cable 10, and cable intermediate joint is settled the inside of metal shell 30, so that cable intermediate joint is protected.This metal shell 30 can be fixed on the inwall of cable trough, can adopt the bolt suspension type to be installed on the cable bearer inwall.
The above case only is the preferable case study on implementation of the utility model; be not to limit practical range of the present utility model with this; so the equivalence that all shapes according to the utility model, structure and principle are done in any electric pressure changes, and all should be covered by in the protection range of the present utility model.
