Description

Easy-stripping cable and manufacturing method thereof

The invention relates to an easy-stripping cable and a manufacturing method thereof, and more particularly, to an easy-stripping cable having convenience and capable of saving man-hours and a manufacturing method thereof.

Please refer to FIG. 1 for the operation diagram of the conventional cable 400. The cable 400 is mainly used for controlling installation, connecting equipment, transmitting power, transmitting signals, and the like. A typical cable 400 includes a plurality of wires 410 and a covering layer 420 covering the wires 410. The lead wire 410 includes a core wire 411 made of a conductive metal such as copper, and an insulating layer 412 covering the outside of the core wire 411. The core wire 411 is used as a basic component for power or signal transmission, and the insulation layer 412 is wrapped around the periphery of the core wire 411 to avoid mis-contact between multiple core wires 411. During use, the insulating layer 412 outside the core wire 411 must be removed to expose the core wire 411, and then the core wire 411 is electrically connected to components such as a circuit and a conductive terminal by soldering or the like. In addition, since a general circuit has positive and negative poles or a three-phase power configuration, a plurality of wires 410 are usually connected through a coating layer 420 (such as PVC glue) to form a cable 400 during manufacture.

When the conventional cable 400 is peeled, the covering layer 420 is first cut through the wire stripper 300 and must be cut to a depth of the central axis of the cable before the user can peel the covering layer 420 and take out the wire 410. This arrangement needs to be handled carefully to prevent the wire stripper 300 from damaging the insulation layer 412 of the wire 410 and destroying the insulation arrangement. Furthermore, the cross-section of the conventional cable 400 as shown in FIG. 1 is two circles side by side. Therefore, it is difficult to maintain the perfect roundness when the plastic is extruded, which leads to the ellipse-like deformation of the finished product, which will affect the Convenience when pulling cables after construction. In addition, the cable 400 has a predetermined specification limit. In order to meet the requirements of the cable 400 products below the specifications, such as insulation conditions, some manufacturers will increase the thickness of the coating layer 420 during production, making the finished product higher than the specification limit. However, the increase in the thickness of the coating layer 420 also increases the difficulty of peeling and reduces the overall flexibility of the cable 400, which severely limits the flexibility of the cable 400 when wiring. Therefore, taking into account the shortcomings of the previous technology, how to balance the ease of stripping and use with the flexibility of the cable itself is a problem that the industry is desperate to overcome.

The purpose of the present invention is to solve the problems that conventional cables are not easy to peel and have low flexibility.

To achieve the above object, the present invention provides an easy-stripping cable including a covering portion, a plurality of electrical connection portions, and a plurality of filling portions. The covering portion includes a tubular inner covering layer, an axis defined by the inner covering layer, and an outer covering layer arranged around the inner covering layer. Each of the electrical connection portions includes a conductor, and an insulation layer disposed around the conductor. Each of the insulation layers is adjacent to each other, and is distributed at the opposite end of the inner coating layer based on the axis. Each of the filling parts is distributed in the remaining space in the inner covering layer, and includes a body. Each of the filling systems rests on the side edges of two adjacent insulating layers, and is distributed on the axis as a reference. Opposite ends in the inner coating. Wherein, the easily peelable cable has a fixed state in which each of the electrical connection portions and each of the filling portions are bound through the inner covering layer. When the inner covering layer and the outer covering layer are partially cut, the easily peelable cable has a peeled state that naturally disperses each of the electrical connection portions and each of the filling portions in the corresponding split area.

Further, the conductor includes a plurality of conductive cores, and one of the conductive cores is surrounded by other conductive cores.

Further, the total number of the conductive cores is seven.

Further, the cross-section of the easily peelable cable is perfectly circular.

Further, each of the filling portions includes a support core passing through the body.

Further, each of the electrical connection portions and each of the filling portions are disposed in a twisted wire.

The layers are separated from each other, so that each of the electrical connection portions can be in an automatically interspersed state. Moreover, the user can directly perform a splitting action toward the filling portion without damaging the insulating layer, and can achieve the purpose of easy peeling and protecting the insulating layer.

2. The filling part and the inner covering layer of the present invention are separably provided. Instead of using conventional cables, only the inner covering layer covers all the electrical connection portions. Therefore, under the condition of the same thickness, the easy-stripping cable of the present invention has the same protection capability as the conventional cable, and also has higher flexibility, which is beneficial to construction.

Here are some preferred implementation aspects of the technical features and operation methods of this application, which will be described later in conjunction with the illustrations, and provided for review and reference. Furthermore, the scale of the drawings in the present invention is not necessarily drawn according to actual scale for the convenience of explanation, and the scale in the drawings is not intended to limit the scope of protection claimed by the present invention.

Referring to FIG. 5, the inner covering layer 21 fixes each of the filling portion 30 and each of the electrical connection portions 10 at a specific horizontal position in a cross-section of the easily peelable cable 100.

Each of the electrical connection portions 10 includes a conductor 11 and an insulation layer 12 provided around the conductor 11. Each of the insulation layers 12 is located next to each other, and is distributed in the inner covering layer 21 with the axis 22 as a reference. Inside opposite ends. The conductor 11 includes a plurality of conductive cores 111, and one of the conductive cores 111 is surrounded by other conductive cores 111.

Each of the body 31 is placed against the side edge of two adjacent insulating layers 12 and is aligned with the axis. The cores 22 are distributed at the opposite ends of the inner covering layer 21 with reference, and each of the filling portions 30 includes a support core 32 passing through the body 31. The support core 32 may be cotton or the like. In this embodiment, each of the bodies 31 is extruded from the body 31 along the supporting core 32 through a plastic extruder (not shown). With the above structure, the easily peelable cable 100 has a fixed state in which each of the electrical connection portions 10 and each of the filling portions 30 are bound through the inner covering layer 21. When the inner covering layer 21 and the outer covering layer 23 are partially cut, the easily peelable cable 100 further has a peeling that naturally disperses each of the electrical connection portions 10 and each of the filling portions 30 in the corresponding split area 200. status. In addition, the cross-section of the easy-to-peel cable 100 can be maintained as a perfect circle as shown in FIG. 5. Since the cable of the perfect circle type has the same stress on the outer periphery, it can be used for pulling and wiring operations. It can move more flexibly without being hindered, and the overall flexibility of the easy-stripping cable 100 of the present invention is higher than that of a conventional integrally formed covering material.

Referring to FIG. 6, a cross-sectional view of the easy-strip cable 100 according to another embodiment of the present invention is shown. In this embodiment, the number of the electrical connection portions 10 and the filling portions 30 are three, and the insulation layers 12 of each of the electrical connection portions 10 are placed against each other, and are distributed in the center with the axis 22 as a reference. The opposite ends in the inner covering layer 21; each of the filling portions 30 is distributed in the remaining space in the inner covering layer 21, and each of the bodies 31 rests on the side edges of two adjacent insulating layers 12, It is distributed at the opposite ends of the inner covering layer 21 with the axis 22 as a reference. According to the above configuration, the purpose of easy peeling can also be achieved.

Regarding the use manner of the easy-stripping cable 100 of the present invention, referring to FIG. 2 again, the user can first align the wire stripper 300 at the position of the surface of the covering portion 20 corresponding to the filling portion 30, and pierce toward the filling portion 30 After entering the surface position of the filling portion 30, peeling it back to separate each of the electrical connection portions 10 as shown in FIG. Since there is no electrical connection member in the filling portion 30, the user does not need to worry about whether the cutting of the filling portion 30 will bring about an adverse effect. And because the inner covering layer 21 and the filling portion 30 are only a binding connection, the user only needs to cut a relatively short range (the conventional cable must be cut to the cable axis 22), and each of the electrical connection portions can be cut. 10 Take out and use to achieve easy peeling effect.

Hereinafter, a method for manufacturing the easily peelable cable 100 according to the present invention will be described. The method includes the following steps S1 to S4: S1.
