Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of overhead line, including conductor wire core 1, be coated on 1 outside of conductor wire core by polyvinyl chloride system At insulating layer 11 and be coated on the outside of insulating layer 11 nylon material protective case 12.Polyvinyl chloride insulation function admirable, energy The phenomenon that electric leakage, open circuit occurs in cable is enough effectively reduced.And 12 high mechanical strength of protective case of nylon, fatigue durability and corrosion-resistant Performance is good, can be good at protecting conducting wire.
As shown in Figures 2 and 3, insulating layer 11 winds conductor wire core 1 by an eradication marginal zone 2 and is made.The cross section of insulating tape 2 Be square, in 2 cross section of insulating tape it is shorter on one side on integrally formed with bonding jumper 21, the thickness of bonding jumper 21 is less than insulating tape The half of 2 thickness.The side side of bonding jumper 21 is generally aligned in the same plane with the side side in insulating tape 2 far from conductor wire core 1 It is interior.Overlap joint slot 22 is offered on insulating tape 2 on the side side opposite with the side for being connected with bonding jumper 21, overlap joint slot 22 is transversal The shape in face is identical as the cross-sectional shape of bonding jumper 21, and when insulating layer 11 is wrapped on conductor wire core 1, bonding jumper 21 is embedded In overlap joint slot 22.Tearing port 23 is offered on bonding jumper 21, the axis of conductor wire core 1 is perpendicular to flat where tearing port 23 Face.The oiliness glue-line 24 of waterproof is provided between bonding jumper 21 and overlap joint slot 22.Setting in this way, people can pass through Tearing port 23 easily tears insulating layer 11, while the gap at tearing port 23 is overlapped slot 22 and oiliness glue-line 24 closes, Make also to can be good at being sealed after overhead line is bent repeatedly, water is made to be not easy to penetrate into insulating layer 11 along tearing port 23. When tearing insulating layer 11 along tearing port 23, the plane torn makes to be torn people perpendicular to the axis of conductor wire core 1 11 end face of insulating layer keep smooth, carry out subsequent installation convenient for the overhead line.The side of overlap joint slot 22 is bonded in bonding jumper 21 Face, which protrudes above, is formed with connection strap 25, and connection strap 25 is parallel with insulating tape 2.It is opened on the side that overlap joint slot 22 is bonded bonding jumper 21 Equipped with the cross-sectional shape link slot 26 equal with 25 cross-sectional shape of connection strap, it is wrapped on conductor wire core 1 in insulating layer 11 When, connection strap 25 is embedded in link slot 26.The area being bonded between bonding jumper 21 and overlap joint slot 22 is increased, to increase oil Property glue-line 24 area, make bonding jumper 21 and overlap joint slot 22 between can adhere to it is more firm.
As shown in Figure 2 and Figure 4, it is coated with glue on side side of the insulating tape 2 far from conductor wire core 1, after air drying The harder hardened layer 3 of quality can be become.In people when shearing the overhead line, shown if cutting off in protective case 12(Fig. 1) it arrives When at insulating layer 11, it can be clearly felt that the feel of cutting is different.To prompt operator to cut to insulation Layer 11, cuts with caution when carrying out subsequent cutting.Tread plate is protruding with close to the side of conductor wire core 1 in insulating tape 2 31.When insulating tape 2 is coated with conductor wire core 1, tread plate 31 makes conductor wire core 1 be not easy the Slideslip in insulating layer 11. After insulating tape 2 is wrapped in and forms insulating layer 11 on conductor wire core 1, tightening ring 32 is equipped in 11 outer sheath of insulating layer.Tightening ring Crushing block 33 there are three being formed is protruded on 32 medial surface, the spacing between two adjacent crushing blocks 33 is equal.Tightening ring 32 The phenomenon that insulating layer 11 capable of being tightened, the junction between insulating tape 2 is made to be less prone to loosening.Tear insulating layer 11 when It waits, by mobile tightening ring 32, is located at tightening ring 32 at the position to be torn, tearing port 23 tears insulating layer 11 later, rises To the effect of limit, the phenomenon that being less prone to excessive tearing's insulating layer 11.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
