Abstract
The utility model provides a signal wire of a cable television, and relates to the technical field of the manufacture of cables. The signal wire of the cable television comprises an oxygen-free copper core, wherein a polyurethane foam layer, an aluminum foil shielding layer, a steel wire woven layer and an outer sheath layer are arranged at the outer part of the oxygen-free copper core in sequence from inside to outside, and an adhesive layer is arranged between the oxygen-free copper core and the polyurethane foam layer. According to the signal wire of the cable television, the problems of inconvenience for installation and poor contact caused by relative shrink of the oxygen-free copper core are solved.
Description
Technical field
The utility model relates to a kind of manufacturing technology field of cable.
Background technology
Existing cable TV signal line comprises the oxygen-free copper core, outside said oxygen-free copper core, sets gradually polyurethane foam, foil shielding layer, steel wire braid, external sheath layer from inside to outside; Play takes place in the holding wire of this structure easily between its oxygen-free copper core and the polyurethane foam, when length was apart from unwrapping wire especially really, each outer layer of oxygen-free copper core was stretched, and the oxygen-free copper core shrinks relatively, makes troubles to installation; After being exactly long-time the use in addition, outer polyurethane foam of oxygen-free copper core and external sheath layer expand, and the oxygen-free copper core can cause loose contact by the top from the contact is installed.
Summary of the invention
The utility model provides a kind of cable TV signal line, and purpose is to solve the problem that play takes place between existing holding wire oxygen-free copper core and the polyurethane foam.
The utility model comprises the oxygen-free copper core, outside said oxygen-free copper core, sets gradually polyurethane foam, foil shielding layer, steel wire braid, external sheath layer from inside to outside, between said oxygen-free copper core and polyurethane foam, adhesive-layer is set.
The utility model is provided with adhesive-layer between oxygen-free copper core and polyurethane foam; The low-pressure polyethylene layer has very strong stickiness; It can hold tightly together oxygen-free copper core and polyurethane foam; Make and play can not take place between the two, avoided the inconvenient installation that the relative contraction of oxygen-free copper core brings and the problem of loose contact.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Among the figure, 1, the oxygen-free copper core, 2, polyurethane foam, 3, foil shielding layer, 4, steel wire braid, 5, external sheath layer, 6, adhesive-layer.
Embodiment
As shown in Figure 1; This cable TV signal line; Comprise oxygen-free copper core 1, outside oxygen-free copper core 1, set gradually polyurethane foam 2, foil shielding layer 3, steel wire braid 4, external sheath layer 5 from inside to outside, between oxygen-free copper core 1 and polyurethane foam 2, adhesive-layer 6 is set.
Claims (1)
1. cable TV signal line; Comprise the oxygen-free copper core; Outside said oxygen-free copper core, set gradually polyurethane foam, foil shielding layer, steel wire braid, external sheath layer from inside to outside, it is characterized in that between said oxygen-free copper core and polyurethane foam, adhesive-layer being set.
