Chinese utility model patent (publication number: CN 204315268U; Publication date: 2015.01.09) disclose a kind of copper sheath mineral insulation fire-resisting cable, comprise conductor and envelope inorganic ceramic powder insulating barrier, copper sheath, the corrosion-resistant sheath of oxygen barrier of conductor successively.
When using this cable to carry out wiring, normally first the position cutting outside the end conductor of two cables is removed, then be wound around or head and the tail welding by the conductor of two cables head and the tail, then two cables are fixed together by electricity consumption adhesive plaster, electric adhesive plaster also plays insulating effect in the outside of conductor.Significantly, this cable carries out wiring and comparatively bothers, and loses time.
Summary of the invention
In order to solve the problem, the utility model provides a kind of wiring conveniently single-core cable.
The purpose of this utility model realizes by following technical proposal:
Single-core cable, the core comprising metal material and the restrictive coating be coated on outside core, it is characterized in that, the two ends of described core have connecting portion one and the connecting portion two with connecting portion one mating shapes respectively, after described connecting portion one is connected with connecting portion two, the shape of the cross section that described connecting portion one combines with connecting portion two is suitable with the shape of core cross section, described restrictive coating is mutually concordant with the outer end of connecting portion two in the outer end at connecting portion one place, the other end of described restrictive coating is mutually concordant with the root of connecting portion one, between described connecting portion one and connecting portion two, there is fixed structure.
When two cables join end to end, after namely the connecting portion one of first cable is connected with the connecting portion two of second cable, connecting portion one and connecting portion two entangle in the outer end at connecting portion one place by restrictive coating, therefore, this part of restrictive coating serves fixing and insulating effect on connecting portion one and connecting portion two.Owing to having fixed structure between connecting portion one and connecting portion two, after connecting portion one is connected with connecting portion two, both, by stable the linking together of fixed structure, are beneficial to current delivery.
In above-mentioned single-core cable, described connecting portion one has pawl one, described connecting portion two has pawl two, after described connecting portion one is connected with connecting portion two, described pawl one is interlockingly connected with pawl two.Due to connecting portion one and the setting of connecting portion two upper inverted tooth, after connecting portion one is connected with connecting portion two, being interlockingly connected between pawl one and pawl two, make can firmly be connected between connecting portion one with connecting portion two, its wiring more for convenience.
In above-mentioned single-core cable, described connecting portion one and connecting portion two are all in semi-cylindrical, the half-terete planar section of described connecting portion one is inclined-plane and the cross section of connecting portion one becomes large from outside to inside gradually, described pawl one is positioned on the half-terete planar section of connecting portion one, the half-terete planar section of described connecting portion two is inclined-plane and the cross section of connecting portion two becomes large from outside to inside gradually, and described pawl two is positioned on the half-terete planar section of connecting portion two.Above-mentioned connecting portion one and the concrete shape of connecting portion two are set, when wiring, only connecting portion one and connecting portion two need be plugged.In addition, due to connecting portion one and the setting of connecting portion two ramp, make to lean on nearer between connecting portion one and connecting portion two, pawl one therebetween and the connection better effects if of pawl two, make the connection that two cables are more stable.
In above-mentioned single-core cable, have retainer ring in described restrictive coating, described retainer ring is positioned at the outside of connecting portion one.Retainer ring plays fixation to the connection of the two after connecting portion one is connected with connecting portion two.Because general restrictive coating hardness is softer, therefore, retainer ring is set in restrictive coating, position-limiting action is played to connecting portion one and connecting portion two, avoid connecting portion one to be separated with connecting portion two, make cable connection comparatively stable.
This single-core cable, by connecting portion one and the pawl on connecting portion two and ramp structure, adds the effect of restrictive coating internal fixtion ring, and when after two cable connections, connect comparatively firm, its wiring also more for convenience, improves the operating efficiency of wiring, has saved the time.

Embodiment
As shown in Figure 1, this single-core cable comprises the core 1 of metal material and the restrictive coating 2 be coated on outside core 1.
The two ends of core 1 have connecting portion 1 and the connecting portion 24 with connecting portion 1 mating shapes respectively, and after connecting portion 1 is connected with connecting portion 24, the shape of the cross section that connecting portion 1 and connecting portion 24 combine is suitable with the shape of core 1 cross section.Between connecting portion 1 and connecting portion 24, there is fixed structure.
Concrete, as shown in Fig. 3, Fig. 4 and Fig. 1, connecting portion 1 and connecting portion 24 are all in semi-cylindrical, the half-terete planar section of connecting portion 1 is inclined-plane and the cross section of connecting portion 1 becomes large from outside to inside gradually, pawl one 3a is positioned on the half-terete planar section of connecting portion 1, the half-terete planar section of connecting portion 24 is inclined-plane and the cross section of connecting portion 24 becomes large from outside to inside gradually, and pawl two 4a is positioned on the half-terete planar section of connecting portion 24.Connecting portion 1 has pawl one 3a, connecting portion 24 has pawl two 4a, after connecting portion 1 is connected with connecting portion 24, pawl one 3a and pawl two 4a is interlockingly connected.Fixed structure is pawl one 3a and pawl two 4a.
Restrictive coating 2 is mutually concordant with the outer end of connecting portion 24 in the outer end at connecting portion 1 place, and the other end of restrictive coating 2 is mutually concordant with the root of connecting portion 1.Have retainer ring 5 in restrictive coating 2, retainer ring 5 is positioned at the outside of connecting portion 1.The material of retainer ring 5 is steel.
As shown in Figure 2, when two cables join end to end, when namely the connecting portion 1 of first cable is connected with the connecting portion 24 of second cable, in the process, only connecting portion 1 and connecting portion 24 need be plugged.In addition, due to connecting portion 1 and the setting of connecting portion 24 ramp, what connecting portion 1 and connecting portion 24 were leaned on is nearer, and the connection better effects if of pawl one 3a therebetween and pawl two 4a, makes the connection that two cables are stable.
Due to connecting portion 1 and the setting of connecting portion 24 upper inverted tooth, after connecting portion 1 is connected with connecting portion 24, being interlockingly connected between pawl one 3a and pawl two 4a, make can firmly be connected between connecting portion 1 with connecting portion 24, its wiring more for convenience.
Connecting portion 1 and connecting portion 24 entangle in the outer end at connecting portion 1 place by restrictive coating 2, and therefore, this part of restrictive coating 2 serves fixing and insulating effect on connecting portion 1 and connecting portion 24.Retainer ring 5 plays fixation after connecting portion 1 is connected with connecting portion 24.Because general restrictive coating 2 hardness is softer, therefore, retainer ring 5 is set in restrictive coating 2, position-limiting action is played to connecting portion 1 and connecting portion 24, avoid connecting portion 1 to be separated with connecting portion 24, make cable connection comparatively stable.
