Hole 31 generally adopts screwed hole, to facilitate quick connection, dismounting of the connection sleeve pipe externally between cable accessory.Described partly leads
The excircle of 1 ring main insulating layer of electric outer layer 2 is arranged, and being fixedly connected between portion 12 and main insulating layer 2 on semiconductive outer layer 1 is formed
Interlocking fixed structure, described spacing preiection 11 exposes to major insulation with the first grafting mating surface 13 in the portion that is fixedly connected 12
Layer 2.Connection lug 14 is also set up on the outer circumference surface of spacing preiection 11, through hole 15 is opened up on the connection lug 14, by setting
Connection lug 14, through hole 15 are put, the ground connection that can facilitate connection sleeve pipe uses.Generally, if the connection lug 14 can be arranged
Dry, the connection lug 14 shown in Fig. 2 is provided with 3, and several connection lug 14 ring spacing preiection, 11 outer circumference surfaces are uniform
Distribution.In several connection lugs 14, one of connection lug 14 is grounded, and remaining connection lug 14 is standby.
Connection sleeve pipe of the present utility model is used cooperatively with separable connector, center conductor therein 3 and power equipment
Connection, to meet through-flow demand.As shown in figure 3, the two ends of the connection sleeve pipe respectively with the grafting of front slotting type separable connector 4
Fixed, by the spacing preiection 11 arranged in connection sleeve pipe, the outer circumference surface for making connection sleeve pipe forms step-like curved surface, can be with
Guarantee that the grafting between connection sleeve pipe and front slotting type separable connector 4 is installed in place.Wherein, on the semiconductive outer layer 1
Intermediate location between spacing preiection 11 and the portion that is fixedly connected 12 forms circular arc transition structure, the described portion 12 that is fixedly connected
Interlocking end face is also configured as arc-shaped structure, as shown in figure 1, producing corner discharge when in use to be effectively prevented connection sleeve pipe
Phenomenon, it is to avoid connection sleeve pipe fails because breakdown.
As shown in Figure 1, Figure 3, the first grafting mating surface 13 on the semiconductive outer layer 1 is designed as cone structure, described
The second grafting mating surface 21 on main insulating layer 2 is also configured as cone structure；Preferably, the first grafting mating surface 13 and
The taper design of two grafting mating surfaces 21 is consistent so that the inserted terminal mating surface of the connection sleeve pipe is formed as smooth conical surface knot
Structure.Using such structure design, the grafting between connection sleeve pipe and front slotting type separable connector 4 can on the one hand installed
It is convenient, on the other hand may insure that connection sleeve pipe is complete with the residual air of the front slotting matching part of type separable connector 4
It is discharged, is produced because there is residual bubble with the front slotting matching part of type separable connector 4 with being effectively prevented connection sleeve pipe
Atmospherical discharges phenomenon, it is ensured that the use of connection sleeve pipe is safe and reliable, is conducive to improving the service life of connection sleeve pipe.Preferably,
As shown in figure 1, length L2, L3 positioned at the first grafting mating surface 13 of the opposite sides of spacing preiection 11 is respectively set to 5mm-
15mm.If the length of the first grafting mating surface 13 be more than 15mm, on the one hand cause connection sleeve pipe extended length, cause its into
