Abstract
The utility model discloses a kind of mineral cable multicore intermediate connector, belong to cable installing area, solve traditional intermediate connector and trouble is installed, the problem connecting defective tightness between weak, the conductor of degree of safety is installed.Mainly comprise internal thread seamless pipe, described internal thread seamless pipe two ends are respectively provided with a gland head end-blocking, are provided with splicing ear in the middle of at least one screw connecting-type in described internal thread seamless pipe.The utility model simple installation, Strength Safety is high, and cable conductor connects closely, and conductive effect is good, and structure is simple, and be easy to manufacture, practical value is high, can be widely used in cable installing area.
Description
Technical field
The utility model relates to a kind of cable connecting arrangement, specifically, particularly relates to a kind of mineral cable multicore intermediate connector.
Background technology
Because mineral insulated cable production length is by the restriction of cable raw material length, or by the impact that different electric loop cable is equipped with in unwrapping wire process, make in cable laying installation process, need to adopt intermediate connector to be connected together by two same size cables, to ensure the needs meeting line length.
Now in practice, no matter the basis brass pipe that adopts, as outer sheath tube, is that single core or multicore inside adopt copper aluminium hydraulic pressed connecting pipe to carry out crimping connection more.China Patent No. CN 102468640A, date of publication on 05 23rd, 2012, the name of innovation and creation is called Special intermediate connector for fireproof cables, this application case makes public for the first time a kind of intermediate connector connected together by cable, although have fire-proof function, the connection that the internal structure of this application case still adopts traditional copper aluminium hydraulic pressed connecting pipe mode to carry out between cable.Traditional this connected mode, install trouble, especially multicore, each needs carries out crimping work, and trouble degree more highlights.In addition, install security intensity also more weak, the connection defective tightness between cable conductor, thus it is poor to show conductive effect, what have even there will be cable obscission.
Summary of the invention
The utility model discloses a kind of mineral cable list core intermediate connector, trouble is installed for solving traditional intermediate connector, the problem connecting defective tightness between weak, the conductor of degree of safety is installed.
The utility model is achieved through the following technical solutions:
A kind of mineral cable multicore intermediate connector, comprise internal thread seamless pipe, described internal thread seamless pipe two ends are respectively provided with a gland head end-blocking, are provided with splicing ear in the middle of at least one screw connecting-type in described internal thread seamless pipe.
In the middle of described screw connecting-type, splicing ear comprises special copper pipe, and any one side of described special copper pipe is provided with some screw holes and corresponding fastened by screw nail.
Any one side in the middle of described screw connecting-type on splicing ear is provided with pry hole.
The material of described internal thread seamless pipe is alloy brass pipe or T2 copper tube.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model simple installation, Strength Safety is high, and cable conductor connects closely, and conductive effect is good;
2. the utility model structure is simple, is easy to manufacture, and practical value is high, can be widely used in cable installing area.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
In figure: 1. internal thread seamless pipe; 2. gland head end-blocking; 3. splicing ear in the middle of screw connecting-type; 4. special copper pipe; 5. fastened by screw nail; 6. spy upon hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of mineral cable multicore intermediate connector, comprise internal thread seamless pipe 1, described internal thread seamless pipe 1 two ends are respectively provided with a gland head end-blocking 2, are provided with splicing ear 3 in the middle of at least one screw connecting-type in described internal thread seamless pipe 1.
In the middle of described screw connecting-type, splicing ear 3 comprises special copper pipe 4, and any one side of described special copper pipe 4 is provided with some screw holes and corresponding fastened by screw nail 5.
Any one side in the middle of described screw connecting-type on splicing ear 3 is provided with pry hole 6.
The material of described internal thread seamless pipe 1 is alloy brass pipe or T2 copper tube.
The quantity of the screw hole on described special copper pipe 4 is 4-10, the utility model for the quantity of screw hole for 6.
Splicing ear 3 in the middle of 2-10 screw connecting-type can be provided with in described internal thread seamless pipe 1.
Described special copper pipe 4 is hexangle type copper pipe.
Embodiment 1: in the middle of the screw connecting-type in internal thread seamless pipe 1, splicing ear 3 quantity is 3, can realize the continued access of three core cables.Turn on fastened by screw nail 5 counterclockwise, as shown in drawings the end of both sides cable is accessed respectively the two ends of splicing ear 3 in the middle of screw connecting-type, more clockwise tighten the screws clench nail 5 fastening both sides cable.Same method operates splicing ear 3 in the middle of remaining two screw connecting-types again.The intermediate ends position being provided with that plane of screw hole is provided with pry hole 6, and whether described pry hole 6 is mainly used to detected temperatures and is connected good with observation wire.The core exposed part of cable adopts the high temperature heat-resistant draw and high pressure water-proof self-adhesion band to carry out security protection.
Embodiment 2: in the middle of the screw connecting-type in internal thread seamless pipe 1, splicing ear 3 quantity is 4, can realize the continued access of four-core cable.Turn on fastened by screw nail 5 counterclockwise, as shown in drawings the end of both sides cable is accessed respectively the two ends of splicing ear 3 in the middle of screw connecting-type, more clockwise tighten the screws clench nail 5 fastening both sides cable.Same method operates splicing ear 3 in the middle of remaining three screw connecting-types again.The intermediate ends position being provided with that plane of screw hole is provided with pry hole 6, and whether described pry hole 6 is mainly used to detected temperatures and is connected good with observation wire.The core exposed part of cable adopts the high temperature heat-resistant draw and high pressure water-proof self-adhesion band to carry out security protection.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
