Description

Cable convenient to wire

Technical Field

The invention relates to a cable, in particular to a cable convenient to route.

Background

The cable is used as a signal connecting line among various electric appliances, instruments and automatic devices, is mainly used for various functions such as signal transmission and control signal transmission in occasions such as control and monitoring interlocking loops, protection lines and the like, and is widely applied to important economic fields such as various industrial and mining enterprises, transportation and the like. In the cable laying process, sometimes a plurality of cables are laid in the same pipeline. In this case, if the cable line needs to be identified, the cable needs to be cut and the cable line needs to be detected by a dedicated device. Therefore, the conductivity of the cable is easily affected, and the line detection is troublesome.

Disclosure of Invention

The invention aims to provide a convenient wiring cable which is simple in structure and easy to distinguish.

In order to solve the above technical problems, the present invention provides a cable convenient for wiring, which comprises a filling layer, a tearable outer sheath layer and a plurality of inner cores, the inner core comprises three cable conductors, an insulating layer and a coloring identification layer from inside to outside in sequence, the insulating layer comprises a main body, an embedded groove and a protruding part, the main body is coated outside the three cable conductors, the cross section of the main body is square, the embedded groove is arranged in the longitudinal direction of one side of the main body, the protruding part is arranged in the longitudinal direction of the other side of the main body, the coloring identification layer is coated on the outer surface of the insulating layer, the embedded groove of one inner core is matched with the protruding part of the other inner core, a plurality of inner cores are embedded together through the embedded groove and the protruding part to form an inner, the outer jacket layer cladding that can tear is in a plurality of inner core outside, and the filling layer is filled between a plurality of inner core and the outer jacket layer that can tear, and the outer jacket layer that can tear is a spiral winding and can tears the area on the inner core.

In order to protect the cable, the cable is convenient to route, and the protective belt is arranged in the longitudinal direction of the tearable outer jacket layer.

Preferably, the number of the inner core bars is three.

The invention has the beneficial effects that: the arrangement of the tearable outer jacket layer is convenient for wiring the cable, when a cable head needs to be manufactured in wiring, the tearable outer jacket layer can be directly torn, so that the cable head is convenient to manufacture, and meanwhile, the arrangement of the protective belt can prevent the cable from directly tearing the tearable outer jacket layer due to careless external force in the laying process, so that the cable is protected; the coloring identification layer is arranged, so that the cable can be distinguished conveniently when the pipeline is maintained or detected; the setting of bulge and embedded groove on the inner core can be convenient for inlay a plurality of inner core together, forms the inner core strip, and when the wiring, when can tearing overcoat layer tear out, the inner core is not in the disorder of arranging, is convenient for arrange the line.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1-2, the invention provides a conveniently wired cable, which comprises a filling layer 1, a tearable outer sheath layer 2 and a plurality of inner cores 3, wherein each inner core 3 sequentially comprises three cable conductors 301, an insulating layer 302 and a colored identification layer 303 from inside to outside, the insulating layer 302 comprises a main body 3021, an inner embedding groove 3022 and a protrusion 3023, the main body 3021 covers the outer sides of the three cable conductors 301, the cross section of the main body 3021 is square, the longitudinal direction of one side of the main body 3021 is provided with the inner embedding groove 3022, the longitudinal direction of the other side of the main body 3021 is provided with the protrusion 3023, the colored identification layer 303 covers the outer surface of the insulating layer 302, the inner embedding groove 3022 of one inner core 3 is matched with the protrusion 3023 of another inner core 3, the plurality of inner cores 3 are embedded together with the protrusion 3023 to form an inner core bar 4, the tearable outer sheath layer 2 covers the outer sides of the plurality of the inner cores 3, the filling layer 1 is, the tearable jacket layer 2 is a tearable tape spirally wound on the inner core 3.

The cable convenient to route further comprises a protective tape 5, and the protective tape 5 is arranged in the longitudinal direction of the tearable jacket layer 2.

In this embodiment, there are three inner core bars 4.

In this embodiment, the coloring identification layer 303 is provided with a label.

The method can be realized by adopting the electrical double-sided adhesive tape which is simplest and is spirally arranged on the outer side of the cable, or adopting the plastic tearing tape similar to air water or seasoning heads, and the method can be realized, of course, the specific electrical tape in the cable field has the best effect, the strength is also ensured when the tearing action is ensured, and meanwhile, the protective tape 5 is arranged, so that the situation that the tearable outer jacket layer 2 is directly torn due to careless external force in the laying process of the cable can be prevented, and the cable is protected; the simplest embodiment of the protective belt is that the adhesive tape is adopted, which mainly prevents the misoperation of the tearable layer and provides an adhesive force, of course, the cable adhesive tape adopted in the field of cables has better effect, and the arrangement of the coloring identification layer 303 can facilitate the distinguishing of the cables when the pipelines are maintained or detected; the setting of bulge 3023 and embedded groove 3022 on the inner core 3 can be convenient for inlay a plurality of inner core 3 together, forms inner core strip 4, when the wiring, when can tearing overcoat layer 2 and tear, inner core 3 is not in the confusion of arranging, is convenient for arrange the wiring.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
