Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with the accompanying drawings and be embodied as
The present invention is described in detail for example.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, not
For limiting the present invention.
Connection sleeve pipe as shown in Figure 1, main inclusion semiconductive outer layer 1, main insulating layer 2 and center conductor 3, therein half
Skin 1 is typically by resistivity in 10 ω cm-104Semi-conductive rubber materials processing in the range of ω cm forms, and is partly leading
Spacing preiection 11 is formed on electric outer layer 1, is fixedly connected portion 12, described spacing preiection 11 mutually consolidates formation with the portion that is fixedly connected 12
T shape ledge structure.Described main insulating layer 2 is to be made by rubber insulation material, described center conductor 3 insertion main insulating layer
2 and be fixedly connected between main insulating layer 2, open up cable connecting orifice 31 respectively at center conductor 3 two ends, described cable connection
Hole 31 generally adopts screwed hole, to facilitate quick connection externally and cable accessory between for the connection sleeve pipe, dismounting.Described partly leads
Electric outer layer 1 ring main insulating layer 2 excircle is arranged, and being fixedly connected on semiconductive outer layer 1 is formed between portion 12 and main insulating layer 2
Interlocking fixed structure, described spacing preiection 11 all 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 spacing preiection 11 outer circumference surface, described connection lug 14 opens up through hole 15, by setting
Put connection lug 14, through hole 15, the ground connection of connection sleeve pipe can be facilitated to use.Generally, if described 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.Connect in lug 14 at several, one of lug 14 that connects is grounded, and it is standby that remaining connects lug 14.
The connection sleeve pipe of the present invention and separable connector use cooperatively, and center conductor 3 therein is connected with power equipment,
To meet through-flow demand.As shown in figure 3, the two ends of described connection sleeve pipe are fixed with the grafting of front slotting type separable connector 4 respectively,
By in connection sleeve pipe setting spacing preiection 11, make the outer circumference surface of connection sleeve pipe form step-like curved surface it can be ensured that
Grafting between connection sleeve pipe and front slotting type separable connector 4 is installed in place.Wherein, spacing on described semiconductive outer layer 1
Intermediate location between raised 11 and the portion that is fixedly connected 12 forms circular arc transition structure, the described interlocking being fixedly connected portion 12
End face is also configured as arc-shaped structure, as shown in figure 1, producing corner discharge when using now to be effectively prevented connection sleeve pipe
As, it is to avoid connection sleeve pipe lost efficacy because breakdown.
As shown in Figure 1, Figure 3, the first grafting mating surface 13 on described 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, described 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 this 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 on the one hand can be made to install
Convenient, on the other hand may insure that connection sleeve pipe is complete with the residual air of front slotting type separable connector 4 matching part
It is discharged, produced because residual bubble occurs with front slotting type separable connector 4 matching part with being effectively prevented connection sleeve pipe
Atmospherical discharges phenomenon it is ensured that connection sleeve pipe using safe and reliable, be conducive to improving the service life of connection sleeve pipe.Preferably,
As shown in figure 1, length l2, l3 being located at the first grafting mating surface 13 of spacing preiection 11 opposite sides is respectively set to 5mm-
15mm.If the length of this first grafting mating surface 13 is more than 15mm, on the one hand cause connection sleeve pipe extended length, lead to its one-tenth
This increase, on the other hand also results in creep age distance not, thus easily producing electric discharge phenomena, and then leads to connection sleeve pipe to be damaged.
If the length of this first grafting mating surface 13 is less than 5mm, in connection sleeve pipe and front slotting type separable connector 4 matching part
Easily residual bubble, thus leading to atmospherical discharges phenomenon to produce, be unfavorable for ensureing connection sleeve pipe using safe and reliable.
In the connection sleeve pipe of the present invention, being fixedly connected on described semiconductive outer layer 1 can between portion 12 and main insulating layer 2
It is adhesively fixed between integral, described center conductor 3 and main insulating layer 2 with being consolidated by vulcanization, not only connect reliable,
And Product processing is easily, implementation cost is low.Wherein, the left and right both ends of the surface of described center conductor 3 are respectively exposed to major insulation
Layer 2.Preferably, the left and right both ends of the surface of described center conductor 3 are respectively relative to main insulating layer 2 length l4, l1 outwardly and divide
Not Wei 1mm-3mm, as shown in Figure 1.After the two ends of connection sleeve pipe are fixing with front slotting type separable connector 4 grafting respectively,
As shown in figure 3, can ensure that the connection between center conductor 3 and cable accessory puts in place, and make center conductor 3 and cable accessory
Between there is enough conductive cross-sectional area, it is to avoid come in contact bad between the two, therefore, in center conductor 3 galvanization,
The connecting portion that just can be effectively prevented between center conductor 3 and cable accessory leads to connection sleeve pipe because local temperature is too high
Heat damage.
The connection sleeve pipe of the present invention in actual moving process, because its maximum field intensity concentrates in this connection sleeve pipe
Portion so that the first grafting mating surface 13, second grafting mating surface 21 etc. connect mating surface at electric field intensity be greatly reduced, thus
The shelf depreciation of connection sleeve pipe product and industrial frequency withstand voltage grade is made all to be able to correspondingly significantly be lifted.After tested, its power frequency is resistance to
Up to 117kv/5min, shelf depreciation value is less than 2pc under 48kv to pressure grade, therefore, it can meet 26/35kv grade well
The testing requirement of cable accessory products.This connection sleeve pipe is used cooperatively with separable connector class cable accessory products, Ke Yiyou
The usage safety performance of effect ground lifting separable connector class cable accessory products, such that it is able to guarantee the stability of electric power distribution
And reliability.In addition, this connection sleeve pipe can be additionally used in the conversion of power equipment and connects it can also be used to separable connector
Extension connects.As shown in Figure 3 it is only necessary to be connected to one using a connection sleeve pipe by inserting type separable connector 4 before two
Rise it is possible to insert type separable connector after replacing, thus improve its usage economy of connection sleeve pipe.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention it is noted that all
Any modification, equivalent and improvement of being made within the spirit and principles in the present invention etc., should be included in the guarantor of the present invention
Within the scope of shield.
