Abstract
The utility model relates to the technical field of signal transmission lines, in particular to a wrapping wire for a fire-fighting communication earphone; the utility model comprises a PVC central line tube, wherein copper wires are wound outside the PVC central line tube, polyester fibers are arranged in the center of the PVC central line tube, and the polyester fibers and the PVC central line tube are coaxially arranged; the utility model discloses a central spool of PVC parcel polyester fibre's mode is being dragged by external force, and the central spool of PVC can be elongated, but wholly can not be broken, guarantees signal transmission's stability, is applicable to fire control communication equipment.
Description
Technical Field
The utility model relates to a signal transmission line technical field refers in particular to a fire control communication earphone is with wrapping wire.
Background
Fire control communication earphone, its use occasion is more special, especially in the scene of a fire, more need guarantee the signal transmission of fire control communication earphone, and signal transmission line is generally longer, and the scene of a fire condition is complicated, drags signal transmission line more easily, if signal transmission line is pulled the time and is easily broken, will probably produce more serious consequence like this, ordinary transmission line pull resistance is not enough, has not satisfied the special requirement of fire control communication.
Therefore, based on the above-mentioned defect of the existing lapping wire for the fire communication earphone, the existing lapping wire for the fire communication earphone needs to be improved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fire control communication earphone is with around package not enough to prior art, this fire control communication earphone has solved the existence of current transmission line with around package: the tensile property is not enough, the requirement of fire-fighting communication can not be met, and the like.
In order to achieve the purpose, the utility model is realized by the following technical scheme: fire control communication earphone is with wrapping line, including PVC center spool, the outside of PVC center spool is around having the copper line, and the center of PVC center spool has polyester fiber, and polyester fiber and PVC center spool are coaxial to be set up.
The center of the PVC central line pipe is provided with a nylon wire, and the nylon wire and polyester fiber are twisted into a folded yarn.
The section of the copper wire is circular.
The copper wire comprises polyester fibers and copper wires, and a plurality of copper wires are wrapped on the polyester fibers to form the copper wire.
When the copper wires are wrapped, each circle of copper wires are contacted with each other.
The beneficial effects of the utility model reside in that: adopt PVC center spool parcel polyester fiber's mode, when being dragged by external force, PVC center spool can be elongated, but wholly can not be broken, guarantees signal transmission's stability, is applicable to fire control communication equipment.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the structure after stretching.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1-2, the utility model discloses fire control communication earphone includes with winding: PVC (Polyvinyl chloride) center line 1, copper wire 2 and polyester fiber 3.
The utility model discloses a PVC center spool 1, PVC center spool 1's the outside is around having copper line 2, and PVC center spool 1's center has polyester fiber 3.
The center of the PVC central line tube 1 of the utility model is provided with a nylon thread, and the nylon thread and the polyester fiber 3 are twisted into a folded yarn.
The utility model discloses a copper line 2's cross-section is circular, follows the removal easily when being stretched.
The utility model discloses a copper line 2 includes polyester fiber 3, copper wire, and many copper wires form copper line 2 around the package on polyester fiber 3, increase copper line 2's pull resistance on the one hand, and on the other hand guarantees that signal transmission is stable.
Of course, the above-mentioned embodiments are only preferred examples of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes or modifications made by the structure, features and principles described in the claims of the present invention should be included in the claims of the present invention.
