Ωcm-104Semi-conductive rubber materials processing in the range of Ω cm is formed, and the thickness of outer semiconducting layer therein 1 is designed as
4.05mm-5.05mm.The main insulating layer 2 is formed as male-tapered structure in the left end of rear loading type separable connector product, removes
Outside the main insulating layer 2 of the male-tapered structure division, the outer surface of the main insulating layer 2 of remainder coated outer semiconducting layer
1, described 1 end of outer semiconducting layer forms first and is fixedly connected portion 11, described first be fixedly connected portion 11 and main insulating layer 2 it
Between form interlocking fixed structure, and first the first grafting mating surface 12 being fixedly connected in portion 11 exposes to main insulating layer 2.It is described
Main insulating layer 2 is internally formed the second die cavity 22 of first die cavity 21 and cylindrical cavity structure of conical cavity structure, in the first type
High voltage shield 4 is set in chamber 21, interior semi-conductive layer 3 is set in the second die cavity 22.Described outer semiconducting layer 1, interior partly lead
Electric layer 3, high voltage shield 4 are linked into an integrated entity with the solidification of main insulating layer 2 respectively, and the right-hand member of the high voltage shield 4 is partly led with interior
Electric layer 3 mutually overlaps, and forms current path.
Above-mentioned rear loading type separable connector during actually coming into operation, high voltage shield therein 4 and interior half
Conductive layer 3 is contacted with high voltage, and its effect is connection conductor and cable of the shielding inside rear loading type separable connector
Gap discharge when being connected with rear loading type separable connector.As maximum field intensity concentrates on the separable company of the rear loading type
Connect inside device so that be connected thereto the electric field intensity at mating surface and be greatly reduced, so that rear loading type separable connector product
Shelf depreciation and industrial frequency withstand voltage grade be all able to correspondingly significantly be lifted, this improves rear loading type separable connector
Safety in utilization, reliability.When the rear loading type separable connector is used cooperatively with front inserting separable connector, may be used also
To extend the cable connection quantity being connected with power equipment, the connection of two or more cable and power equipment is realized.
In order to ensure installation positioning of the rear loading type separable connector with front inserting separable connector when using cooperatively
Accurately, it is reliable, spacing preiection 13 can be formed on outer semiconducting layer 1, the spacing preiection 13 is fixedly connected portion 11 with first
Between form first order ledge structure, also, the shape also and the visible body portion 14 of outer semiconducting layer 1 between of the spacing preiection 13
Into second level ledge structure, as shown in Figure 1 and Figure 2.Further, the first of 1 end of the outer semiconducting layer is fixedly connected portion 11
Interlocking end face can be designed as arc-shaped structure, described first is fixedly connected the transition part between portion 11 and spacing preiection 13
Position, the intermediate location between the spacing preiection 13 and visible body portion 14 also form circular arc transition structure respectively；In described
Second is formed on semi-conductive layer 3 and is fixedly connected portion 31, described second is fixedly connected formation between portion 31 and main insulating layer 2 rabbets admittedly
Fixed structure, and the second interlocking end face for being fixedly connected portion 31 is designed as arc-shaped structure, as shown in figure 1, after to be effectively prevented
Slotting formula separable connector produces corner discharge phenomenon in use, it is to avoid which fails because breakdown.
As shown in figure 1, the first grafting mating surface 12 on the outer semiconducting layer 1 can be designed as cone structure, preferably
Ground, the first grafting mating surface 12 are consistent with the taper design of the male-tapered structure of 2 left end of main insulating layer, so that after this
The inserted terminal mating surface of slotting formula separable connector is formed as smooth cone structure.Using such structure design, one side
The grafting between rear loading type separable connector and front inserting separable connector can be made easier for installation, on the other hand
May insure that rear loading type separable connector and the residual air of front inserting separable connector matching part are discharged completely, with
The matching part that rear loading type separable connector is effectively prevented with front inserting separable connector is produced because there is residual bubble
Raw atmospherical discharges phenomenon, such that it is able to ensure the use of rear loading type separable connector, front inserting separable connector well
It is safe and reliable, be conducive to improving rear loading type separable connector, the service life of front inserting separable connector.In addition, as schemed
Shown in 2, two are formed with the lower body portions of the outer semiconducting layer 1 outwardly and symmetrical connection lug
16, through hole 17 is opened up on connection lug 16, so that the rear loading type separable connector can be by connecting lug 16, through hole 17
To easily form ground state, so that outer semiconducting layer 1 is zero potential, therefore so that the rear loading type separable connector
Surface-discharge will not be produced, safety in utilization, the reliability of rear loading type separable connector is improve.
As shown in figure 3, the first cable auxiliary section 32 and the second cable auxiliary section are formed with described interior semi-conductive layer 3
33, and the maximum outside diameter of the first cable auxiliary section 32 is less than the maximum outside diameter of the second cable auxiliary section 33, adopts
Such structure design, can both strengthen the consolidation reliability between interior semi-conductive layer 3 and main insulating layer 2, while being also beneficial to
Increase creep age distance when rear loading type separable connector is used, prevent from causing rear loading type divide because producing over-discharge phenomenon
From the punch through damage of adapter, to improve the service life of rear loading type separable connector.
For the rear loading type separable connector of 35kV and following electric pressure, although can be in outer semiconducting layer
Arrange spacing preiection 13 to form first order ledge structure on 1, but, after voltage is increased to more than 35kV levels, rear loading type
Separable connector product Jing is often breakdown in this region.For this purpose, the first grafting mating surface 12 on the outer semiconducting layer 1
Length be preferably 5mm-15mm, as shown in Figure 1.If the length of the first grafting mating surface 12 is more than 15mm, on the one hand make
Into the extended length of rear loading type separable connector, cause its cost correspondingly to increase, on the other hand also result in creep age distance not
It is enough, so as to easily produce electric discharge phenomena, and then it is easily caused the punch through damage of rear loading type separable connector.If this first insert
The length of mating surface 12 is connect less than 5mm, is then coordinated with the grafting of front inserting separable connector in rear loading type separable connector
Position easily remains bubble, so as to cause atmospherical discharges phenomenon produce, be also unfavorable for ensure rear loading type separable connector, it is front insert
The safety in utilization of formula separable connector, reliability.By arranging spacing preiection 13 to form first order ledge structure, and outward
After the length of the first grafting mating surface 12 on semi-conductive layer 1 is set to 5mm-15mm, Jing tests, the rear loading type are detachably connectable
The breakdown voltage of device product can be promoted to 117kV/5min, and its shelf depreciation can reach electric discharge under 48kV and be less than 5pC.Therefore,
Safety in utilization, stability and the reliability of rear loading type separable connector product can effectively be lifted.
