Abstract
The utility model discloses a fireproof silicone rubber insulating and shielding flexible wire. A conductor employs a bundle of multiple soft tinning copper wires, and an insulating layer formed by extrusion moulding of ceramic fireproof silicone rubber is arranged outside the conductor, wherein the insulating layer is also a fireproof layer; a shielding layer braided by a soft tinning copper wire is arranged outside the insulating layer, wherein the braiding intensity is greater than 80%, and a multi-strand soft tinning diversion line is arranged in the shielding layer; and an oversheath layer is extruded from the shielding layer. According to the utility model, the conductor and the shielding layer formed by soft tinning wires are employed, thereby effectively preventing the aging and catalytic effects of copper conductors on the insulating layer and the oversheath layer, and ensuring the service life of the insulating layer and the oversheath layer; at the same time, tin coated on the surface of the soft copper wires can effectively prevent self oxidation effects of the soft copper wire conductor and the shielding layer, thereby improving the safety and reliability in the using process.
Description
Technical field
The utility model relates to a kind of shielding flexible cord, relates in particular to a kind of fireproof silicone rubber insulation shielding flexible cord, belongs to technical field of electric wires and cables.
Background technology
The shielding flexible cord is to use conductive fabric, the transmission line that netted braided wire wraps up holding wire.There is the wire of conductor parcel the wire outside shielding conductor, the conductor of parcel is screen, be generally conductive fabric, braiding copper mesh or copper pool (aluminium), screen needs ground connection, external interference signal can be imported the earth by this layer, avoids interference signal and enters the loss that the inner conductor interference reduces signal transmission simultaneously.
The utility model content
It is a kind of simple in structure that the utility model provides, and has good not aging, flexibility, the fireproof silicone rubber insulation shielding flexible cord of long service life.
Scheme of the present utility model is as follows: a kind of fireproof silicone rubber insulation shielding flexible cord, conductor adopt many tin-coated copper soft wire bales to close, and adopt ceramic fireproof silicone rubber extrusion modling insulating barrier outside described conductor, and described insulating barrier and fireprotection layer are same layer; Be provided with the screen of zinc-plated soft copper monofilament braiding outside insulating barrier, count is provided with the soft zinc-plated channelizing line that a multiply bundle closes greater than 80% in the screen; Outside screen, also push one deck external sheath layer.
Described conductor adopts and meets the 5th kind of tinned copper conductor structure among the GB/T3956, and the sectional area of conductor is 0.5～6mm
2, it is 12～16 times that bundle closes pitch.
Described external sheath layer adopts the extrusion modling of ceramic fireproof silicone rubber.
The beneficial effects of the utility model:
1, the utility model adopts conductor and the screen that zinc-plated soft copper monofilament consists of, and can effectively prevent copper conductor to the aging catalytic action of insulating barrier and sheath, to guarantee the useful life of insulating barrier and sheath.Simultaneously, also can effectively prevent the oxidation of soft copper monofilament conductor and shielding itself at the electroplating surfaces with tin of soft copper monofilament, increase the safety and reliability in the use procedure.
2, insulating barrier and fireprotection layer are same layer in the utility model, and take ceramic silicon rubber as material, oversheath adopts the extrusion modling of ceramic silicon rubber, and it has the chemical resistance of wide range.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of fireproof silicone rubber insulation shielding flexible cord, conductor 1 adopts many tin-coated copper soft wire bales to close, and at described conductor 1 outer employing ceramic fireproof silicone rubber extrusion modling insulating barrier 2, described insulating barrier 2 is same layer with fireprotection layer; Be provided with the screen 3 of zinc-plated soft copper monofilament braiding outside insulating barrier 2, count is provided with the soft zinc-plated channelizing line 4 that a multiply bundle closes greater than 80% in the screen 3; Outside screen 3, also push one deck external sheath layer 5.
In the implementation, described conductor 1 adopts and meets the 5th kind of tinned copper conductor structure among the GB/T3956, and the sectional area of conductor is 0.5～6mm
2, it is 12～16 times that bundle closes pitch.Described external sheath layer 5 adopts the extrusion modling of ceramic fireproof silicone rubber.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
