Abstract
The utility model discloses a three-core type signal transmission cable comprising three PVC (polyvinyl chloride) insulators, annealed copper wire conductors and PVC jackets, wherein a PVC jacket is respectively arranged at the outside of each PVC insulator, the three PVC jackets are sequentially connected together in the horizontal direction, and an annealed copper wire conductor is wrapped in each PVC insulator; and a basic reinforcement layer is arranged at the outside of the PVC jackets. The three-core type signal transmission cable disclosed by the utility model has the following beneficial effects: the three-core integral structure is arranged to stabilize the circuit and stabilize the signal transmission, and the three-core type signal transmission cable improves the fire resistance of the cable, so that the three-core type signal transmission cable can be widely applied to audio/video input/output systems.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to a kind of three core formula signal-transmitting cables.
Background technology
The cable of the present input/output that is used for sound/video is because it exists many deficiencies due to the structure aspect electric property; These unreasonable structures are mainly reflected in single structure, mechanical and physical performance, fire protecting performance etc., and exist the too high defective of production cost to a certain extent.
The utility model content
To above defective, the three core formula signal-transmitting cables that the utility model provides a kind of three core Contiuum type structures, helps the signal transmission, has good resistance combustion performance are to overcome many deficiencies of existing like product.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of three core formula signal-transmitting cables; Comprise three PVC insulators, annealed copper wire conductor and PVC sheath; Each PVC insulator exterior is respectively equipped with a PVC sheath, and these three PVC sheaths connect on horizontal direction successively, each PVC insulator internal package one annealed copper wire conductor; Said PVC sheath outside is provided with the strengthening of foundation layer.
The beneficial effect of the described three core formula signal-transmitting cables of the utility model is: through three core Contiuum type structures are set, can make circuit firm, guarantee the stable of signal transmission; Improved cable in the performance of burning aspect fire-resistant; Can be widely used in the input/output of sound/video.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said three core formula signal-transmitting cables of the utility model embodiment.
Among the figure:
1, PVC insulator; 2, annealed copper wire conductor; 3, woven shield; 4, PVC sheath; 5, strengthening of foundation layer.
Embodiment
As shown in Figure 1; The described three core formula signal-transmitting cables of the utility model embodiment; Comprise three PVC insulators 1, annealed copper wire conductor 2 and PVC sheath 4; Each PVC insulator 1 outside is respectively equipped with a PVC sheath 4, and these three PVC sheath 4 levels connect and be tangent successively, each PVC insulator 1 internal package one annealed copper wire conductor 2; Said PVC insulator 1 skin is provided with one deck woven shield 3, and said PVC sheath 4 outsides are provided with strengthening of foundation layer 5.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection range of the utility model.
