Abstract
The utility model discloses a cable. The cable is characterized in that: the inner walls of protective covers are provided with a plurality of annular grooves arranged in a spaced manner in the radial direction of cable cores; the outer surfaces of the protective covers are provided with annular identification rings positionally corresponding to the annular grooves; protection rings made of insulating material are disposed in the annular grooves; and the size of the protection rings is matched with that of the annular grooves. During wiring, the cable can be cut open at the positions of the annular identification rings with a tool, and, since the annular identification rings are corresponding to the annular grooves and the walls of the protective covers are thinner at the positions of the annular grooves, the protective covers can be cut open with less force. The protection rings in the annular grooves can prevent the cable cores from being damaged during cutting, so that the waste of material is prevented, the operation can be performed safely, the cable cutting can be performed rapidly and conveniently and the cabling efficiency is effectively increased.
Description
Technical field
The utility model relates to electric power transportation art, and more particularly, it relates to a kind of cable.
Background technology
The purposes of cable has a lot, and the multiple action such as be mainly used in controlling installation, connection device, transmit electric power is common and indispensable a kind of thing in daily life.
People, in the time of house decoration finishing, usually will lay a large amount of cables, and wiring work is essential.In the time of wiring; people can cut off protective sleeve with pliers; but existing cable protective sleeve is too simple, be to be all close on core, firmly kick the beam and cut not open; the overweight meeting of exerting oneself cuts up core or cut off; the time of having laid cable while so not only having increased wiring, reduce operating efficiency, also cause the waste of material; therefore, be necessary to develop a kind of cable that facilitates wiring, improves wiring efficiency.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of easy-to-connect, efficient cable.
For achieving the above object; the utility model provides following technical scheme: a kind of cable; comprise core; described core is wrapped with the protective sleeve that insulating material is made; described protective sleeve inwall core radial direction is provided with several spaced annular grooves; the described corresponding annular groove of protective sleeve outer surface position is provided with annular identification circle, is provided with the protective ring that insulating material is made in described annular groove, and size and the annular groove of protective ring are suitable.
The utility model is further set to: described protective sleeve has two at least, between two protective sleeves, is provided with connecting portion, and described connecting portion and protective sleeve are structure as a whole.
The utility model is further set to: between described protective sleeve and core, be provided with the screen that semi-conducting material is made.
The utility model is further set to: on described annular identification circle, be printed on producer's mark.
The utility model is further set to: described protective ring is made up of engineering plastics.
By adopting technique scheme; this cable is in the time of wiring; in annular identification, circle place cuts off with instrument, and because annular identification circle is corresponding with annular groove, the wall thickness of annular groove place protective sleeve is thinner; can just can cut off protective sleeve by less power; protective ring in annular groove can prevent that core from being cut up, and has avoided the waste of material, and operation that can be relieved; make trimming work more fast, conveniently, thereby effectively improved the efficiency of wiring.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model cable embodiment;
Fig. 2 is the cutaway view of A-A in Fig. 1.
Reference numeral: 1, core; 2, protective sleeve; 21, annular groove; 22, annular identification circle; 3, protective ring; 4, connecting portion; 5, screen.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model cable embodiment is described further.
A kind of cable; comprise core 1; described core 1 is wrapped with the protective sleeve 2 that insulating material is made; described protective sleeve 2 inwall core 1 radial direction are provided with several spaced annular grooves 21; the described corresponding annular groove of protective sleeve 2 outer surfaces 21 positions are provided with annular identification circle 22; in described annular groove 21, be provided with the protective ring 3 that insulating material is made, the size of protective ring 3 and annular groove 21 are suitable.This cable is in the time of wiring; at annular identification circle, 22 places cut off with instrument; because annular identification circle 22 is corresponding with annular groove 21; the wall thickness of annular groove 21 place's protective sleeves 2 is thinner; can just can cut off protective sleeve 2 by less power; improve the efficiency of trimming; protective ring 3 in annular groove 21 can prevent that core 1 from being cut up; avoid the waste of material; and operation that can be relieved, make trimming work more fast, conveniently, thereby improved the operating efficiency of wiring; just can take down protective ring 3 cutting off after protective sleeve 2, expose core 1 for wiring.Wherein, the distance of adjacent annular groove 21 is 5-20cm; this distance can meet general civilian wiring distance; the degree of depth of annular groove 21 will guarantee that the protective sleeve 2 of the face that is located thereon has enough wall thickness can not torn easily; because protective sleeve 2 wall thickness at annular groove 21 places are thinner; so protective ring 3 can not be made up of electric conducting material, must make with insulating material, to prevent this place's electric leakage.
Described protective sleeve 2 has two at least, between two protective sleeves 2, is provided with connecting portion 4, and described connecting portion 4 is structure as a whole with protective sleeve 2.General cable has zero line and live wire (earth connection in addition having), so protective sleeve 2 is at least established two, for wrapping up respectively zero line and live wire, by connecting portion 4, zero line and live wire is linked together; And at present conventional surpass five class unshielded cables be one group four to twisted-pair feeder, if for surpassing five class unshielded cables, this protective sleeve 2 can be arranged to four; when needed, can be separated with hand, easy to operate; further improve wiring efficiency, improved wiring efficiency.
Between described protective sleeve 2 and core 1, be provided with the screen 5 that semi-conducting material is made.Screen 5 can be avoided, between core 1 and protective sleeve 2, partial discharge occurs, thereby has protected protective sleeve 2, has improved useful life.
On described annular identification circle 22, be printed on producer's mark.Annular identification circle 22 can be indicated the position of the inside ringed groove corresponding with it 21, can stamp producer's mark simultaneously, can be easy to pick out the real producer that cable is produced, and prevents that other people from copying, and increases goodwill degree.
Described protective ring 3 is made up of engineering plastics.Engineering plastics have high strength, high mechanical modulus, low creep, by force wear-resistant, fatigue durability, chemical proofing, anti-electrically, flame resistance, weatherability, dimensional stability be good.Due to physics, the chemical property of its temperature, under bad weather, this protective ring 3 can not produce deformation yet, has guaranteed the normal use of cable, and can also improve the intensity of cable, has strengthened the anti-pressure ability of cable.
