Technical field
The invention belongs to field of cable technology more particularly to a kind of cable accessories.
Background technology
Cable accessory is connecting cable and electric line and the product of related power distribution equipment, is referred generally to each in cable run
The intermediate connection and terminal connection of kind cable, it constitutes power delivery networks together with cable, and cable accessory is mainly foundation electricity
The characteristic of cable structure can restore the performance of cable and the extension of cable length and the connection of terminal.Existing cable is attached
Part structure is complex, is produced by the way of injection or molding, and large-scale molding machine and injector need to be equipped with, and needs to make
It is produced with complicated mold, reduces production efficiency, production cost is higher.
Invention content
The purpose of the present invention is to provide a kind of cable accessories, it is intended to and it is complex to solve existing cable accessory structure,
Product needs to produce using complicated mold, low production efficiency and the higher problem of production cost.
The invention is realized in this way a kind of cable accessory, includes the connection gold utensil of two wire stylets of accessory main body and connection,
The connection gold utensil is set in the accessory main body, and the accessory main body passes through sequentially connected non-linear stress control from inside to outside
Preparative layer, insulating layer and the three-layer co-extruded extrusion of ground shield layer obtain.
The present invention further technical solution be：The connection gold utensil includes the connection of two wire stylets of shielding case and connection
Pipe, the connecting tube are located inside the shielding case, and the shielding case is located inside the non-linear stress control layer.
The present invention further technical solution be：The accessory main body is prefabricated extrusion type accessory main body.
The present invention further technical solution be：The non-linear stress control layer is non-linear resistance material layer.
The present invention further technical solution be：The insulating layer is the third glue-line of electrically insulating silicone rubber layer or second.
The present invention further technical solution be：The ground shield layer is the third glue of semi-conductive silicone rubber layer or semiconductive second
Layer.
The beneficial effects of the invention are as follows：Cable accessory provided by the invention, by sequentially connected from inside to outside continuous
Two wire stylets of accessory main body obtained from three layers of non-linear stress control layer, insulating layer and ground shield layer co-extrusion and connection
Connection gold utensil be composed, mould structure is simple needed for main body production, improves production efficiency and product qualification rate, saves life
Produce cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of cable accessory provided in an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of accessory main body provided in an embodiment of the present invention.
The names of the parts are as follows in figure：
1- accessory main bodies；2- wire stylets；3- connection gold utensils；11- non-linear stress control layers；12- insulating layers；13- ground shields
Layer；31- connecting tubes；32- shielding cases；The first cable shields of 4-；The second cable shields of 5-；6- cables.
Specific implementation mode
In conjunction with above-mentioned description of the drawings specific embodiments of the present invention.
A kind of cable accessory in the present embodiment includes the connection gold utensil 3 of two wire stylets 2 of accessory main body 1 and connection, described
Accessory main body 1 passes through 13 3 layers of sequentially connected non-linear stress control layer 11 from inside to outside, insulating layer 12 and ground shield layer
Co-extrusion and obtain, the cable accessory by control accessory main body 1 length can meet different voltages grade, different cross section cable produce
The requirement of product.Cable accessory provided by the invention passes through sequentially connected non-linear stress control layer, insulating layer from inside to outside
It is composed with the connection gold utensil of two wire stylets of ground shield layer accessory main body obtained from three-layer co-extruded and connection, main body production
Required mould structure is simple, improves production efficiency and product qualification rate, saves production cost.
The connection gold utensil 3 includes shielding case 32 and connects the connecting tube 31 of two wire stylets 2, and the connecting tube 31 is located at institute
It states inside shielding case 32, connection gold pipe 31 is sleeved on the wire stylet 2 of two connections, after determining the docking in place of two wire stylets 2
It is crimped, the shielding case 32 plays uniform electric field, and the effect of stress concentration, the shielding case 32 is prevented to be located at described non-linear
Inside stress control layer 11.When installing cable accessory, the first cable shield 4 and the second cable shield 5 on two cables 6 are set respectively
Set the both ends inside the non-linear stress control layer 11, first cable shield 4 and second cable shield 5 difference
It combines closely with the cable insulation of two connecting cables 6.
The accessory main body 1 is prefabricated extrusion type accessory main body, and the non-linear stress control layer 11 is nonlinear resistance
Material layer is using material resistivity itself and the characteristic outside applying electric field and change at non-linear relation, to solve cable insulation screen
The problem of covering cut-off part electric field integrated distribution, the non-linear stress control layer 11 can realize that high potential and the continuous of low potential connect
It connects so that accessory structure is simple, easy for installation, is not likely to produce installation deviation；The insulating layer 12 is electrically insulating silicone rubber layer or second
Third glue-line, the ground shield layer 13 are the third glue-line of semi-conductive silicone rubber layer or semiconductive second, further serve as uniform electric field, prevent
The effect of stress concentration.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
