Technical Field

The utility model relates to the technical field of electric wires and cables, in particular to a flat sheathed electric wire easy to separate.

Background

An electric wire is an extremely widely used electric energy or signal transmission device, and is generally composed of several wires or groups of wires. During the use of the electric wire, it is often necessary to branch it: in the application scenario of wiring inside mechanical equipment, the electric wire is used for connecting and communicating the power supply and the electric element. When the connection is performed, the electric wires need to be branched due to different positions of power supplies, electric elements and the like, so that the connection and the use are convenient.

The existing electric wire is composed of an insulating sheath and a plurality of insulating wire cores embedded in the insulating sheath, and is of an integrated structure, namely, the insulating wire cores in the electric wire are all twisted together and are difficult to be used separately. When the branch is needed, the insulation sheath at the outer layer needs to be cut open wholly or partially, which destroys the protection structure of the electric wire and easily affects the protection performance of the electric wire.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

As shown in fig. 1 to 2, a preferred structure of a flat sheathed electric wire of the present invention which is easy to be separated.

As shown in fig. 1, the easily separable flat sheath electric wire includes an outer sheath 10, and at least two insulated cable cores 30 arranged side by side in the outer sheath. The upper surface and the lower surface of the outer sheath 10 are recessed relatively inward corresponding to the position between the two insulated wire cores 30, forming a tearing part 11, and the tearing part 11 is convenient for splitting the outer sheath to separate the two insulated wire cores 30.

In a preferred embodiment, the flat sheathed wire is provided with 2 to 4 insulated wire cores 30. Preferably consisting of 2 juxtaposed insulated wire cores. If the number of the insulated wire cores is large, the whole width of the flat sheath wire is large, the winding, storage, transportation and use of the wire are not facilitated, and the cable with the enlarged surface area is easy to damage by foreign objects when the width is large.

In a preferred embodiment, a metal braid 0 is disposed between the insulated cable core 30 and the outer sheath 10.
