Security protection cable

Technical field

The utility model relates to a kind of cable, particularly relates to a kind of security protection cable.

Background technology

The industries such as relative power, communication, broadcasting and TV, there are the objective circumstances such as starting is late, backward in technique, industry standard imperfection in the cable for security protection industry.When communication apparatus puts on display, for the security protection cable of connecting communication equipment use, the mainly effect such as Signal transmissions, power delivery, warning of common purposes.Security protection cable of the prior art adopts the holding wire of a strand, and the heart yearn of holding wire adopts conventional soft copper or zinc-plated soft copper stranded conductor, and a pair holding wire is coated in plastic sheath.Cause that security protection cable of the prior art is large at load capacity, hot strength is large, ultraviolet is stronger etc. comparatively uses in adverse circumstances, there is larger potential safety hazard, anti-theft protection effect effectively can not be played to the communication apparatus of its connection.In addition, when the security protection cable laying of prior art uses on the ground, easy shift position, and also people's pin steps on and easily causes people to tumble because of rolling.

Utility model content

Based on this, be necessary for problems of the prior art, the anti-ultraviolet property that a kind of load capacity is large, tensile strength is large, degree of flexibility is good, stronger is provided, and be convenient to lay the security protection cable used.

A kind of security protection cable, comprising: oversheath, screen, three insulated wires, wire rope structure and line feeders;

The outer wall of described oversheath is coated with ultraviolet ray-resistant material layer, and the cross section of described oversheath is flat structure, is provided with the isolation strip that the length direction along described oversheath extends in described oversheath;

Described wire rope structure is located in the first passage that described isolation strip and described oversheath surround, three described insulated wires are located in the second channel that described isolation strip and described oversheath surround side by side, the coated three described insulated wires of described screen, described line feeder is located in described second channel.

Wherein in an embodiment, described wire rope structure comprises multiply compound cable wire, and described in multiply, compound cable wire is mutually stranded, and often compound cable wire described in one comprises the steel wire that many diameters are 0.15mm, and many described steel wires are mutually stranded.

Wherein in an embodiment, the number of share of stock of described compound cable wire is seven strands, and the quantity of described steel wire is seven.

Wherein in an embodiment, described line feeder is that some stocks gather aramid fiber.

Wherein in an embodiment, the quantity of described line feeder is four, and four described line feeders respectively one_to_one corresponding are located in four gaps formed between three described insulated wires.

Above-mentioned security protection cable employing cross section is the oversheath of flat structure, substantially reduces the thickness of security protection cable, is convenient to lay use, and not easily shift position, plays anti-skidding effect.The coating of ultraviolet ray-resistant material layer effectively prevents ultraviolet to the damage of oversheath, and isolation strip effectively prevents oversheath from swelling, and plays styling.Wire rope structure and line feeder improve security protection cable load capacity, tensile strength and degree of flexibility.

Accompanying drawing explanation

Fig. 1 is the cross-sectional view of the security protection cable of the utility model one embodiment;

Fig. 2 is the cross-sectional view of wire rope structure shown in Fig. 1.

Embodiment

As shown in Figure 1, it is the cross-sectional view of the security protection cable 10 of the utility model one embodiment.Security protection cable 10 comprises: oversheath 100, screen 200, first insulated wire 310, second insulated wire 320, the 3rd insulated wire 330, wire rope structure 400 and line feeder 500.

In order to effectively prevent ultraviolet to the damage of oversheath 100, extend the useful life of security protection cable 10, the outer wall of oversheath 100 is coated with ultraviolet ray-resistant material layer (not shown).

Laying for the ease of security protection cable 10 uses, prevent shift position, and avoid people to step on easily tumbling because of rolling, the cross section of oversheath 100 is flat structure, the isolation strip 600 that the length direction along oversheath 100 extends is provided with in oversheath 100, in actual production, isolation strip 600 and the one-body molded design of oversheath 100.Wire rope structure 400 is located in the first passage 110 that isolation strip 600 and oversheath 100 surround, and the first insulated wire 310, second insulated wire 320 and the 3rd insulated wire 330 are located in the second channel 120 that isolation strip 600 and oversheath 100 surround side by side.Like this, cross section is that the thickness of the security protection cable 10 of flat structure reduces greatly, is convenient to lay use, and not easily shift position, plays anti-skidding effect.In addition, the setting of isolation strip 600 can avoid the first insulated wire 310, second insulated wire 320 effectively, the 3rd insulated wire 330, with wire rope structure 400, relative movement occurs, and prevents oversheath 100 from swelling, plays styling.

In order to avoid external environment is to the interference of transmission signal in the first insulated wire 310, second insulated wire 320 and the 3rd insulated wire 330, coated first insulated wire 310, second insulated wire 320 of screen 200 and the 3rd insulated wire 330, line feeder 500 is located in second channel 120.In the present embodiment, screen 200 is preferably metal aluminum foil, and line feeder 500 is preferably poly-aramid fiber.The quantity of line feeder 500 is four, and four line feeders 500 respectively one_to_one corresponding are located in four gaps formed between the first insulated wire 310, second insulated wire 320 and the 3rd insulated wire 330.

As shown in Figure 2, it is the cross-sectional view of wire rope structure 400 shown in Fig. 1.In order to improve the load capacity of security protection cable 10, tensile strength and degree of flexibility, wire rope structure 400 comprises multiply compound cable wire 410, multiply compound cable wire 410 is mutually stranded, and often one clad steel rope 410 comprises the steel wire 411 that many diameters are 0.15mm, and many steel wires 411 are mutually stranded.In the present embodiment, the number of share of stock of compound cable wire 410 is seven strands, and the quantity of steel wire 411 is seven.

Above-mentioned security protection cable 10 adopts cross section to be the oversheath 100 of flat structure, substantially reduces the thickness of security protection cable 10, is convenient to lay use, and not easily shift position, plays anti-skidding effect.The coating of ultraviolet ray-resistant material layer effectively prevents ultraviolet to the damage of oversheath 100.Isolation strip 600 effectively prevents oversheath 100 from swelling, and plays styling.Wire rope structure 400 and line feeder 500 improve security protection cable 10 load capacity, tensile strength and degree of flexibility.

Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.

The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
