Description

Technical Field

[0001] The utility model relates to the field of wire harnesses, in particular to an electric wire harness that is easy to bend and easy to connect wires. Background Art

[0002] The commonly used BV wires (i.e., hard wires) and BVR wires (i.e., soft wires) on the market are relatively widely used wire harnesses for distribution boxes / cabinets or building power distribution wiring installations.

[0003] In actual use of the existing BV wires or BVR wires of this kind, the BV wires generally involve bending in PVC pipes. However, due to their hard wire structure, it is quite difficult to bend the wires in the PVC pipes during the operation. When directly passing the BVR wires through the terminal block and connecting them with screws during the wiring stage, the wires will spread to the side, resulting in unreliable wiring. Therefore, in order to ensure the reliability of the BVR wire wiring, generally, after stripping the outer skin of the BVR wire, a copper tube or a wire nose (commonly known as a copper nose) is installed at the position where the outer skin is stripped through a special tool, or after soldering, and then connected to the terminal block. As a result, the existing BV wires or BVR wires will have some situations where they are not easy to bend or the wiring process is cumbersome in actual use. Summary of the Invention

[0004] In view of the above deficiencies, the utility model provides an electric wire harness that is convenient for bending operation and can achieve convenient wiring at the same time.

[0005] In order to achieve the above purposes, the utility model adopts an electric wire harness that is easy to bend and easy to connect wires, which includes an outer skin, an inner conductor, and an inner binding part that is flexible and can be bent and shaped. The inner conductor includes a plurality of conductive wires. The plurality of conductive wires respectively pass through the inside of the inner binding part, and the plurality of conductive wires are in contact with each other and fill the inside of the inner binding part. The outer skin is wrapped outside the inner binding part, and a compact connection is formed between the outer skin, the inner binding part, and the plurality of conductive wires.

[0006] The beneficial effects of the above structure are as follows: By setting the inner conductor of the wire harness to several conductive wires, the conductive wires inside the wire harness, that is, the wire cores, can have a structure that is conveniently bendable. The several conductive wires are respectively passed through the inside of the inner binding part, and the several conductive wires are in contact with each other and fill the internal structure of the inner binding part. This design can ensure that when the inner conductor adopts the structure of several conductive wires, through the action of the inner binding part, the outside of the conductive wires is bound. That is, the entire coiled wire harness is related to the inner binding part, thereby avoiding the situation where when fasteners such as screws and bolts act on the wire cores of the wire harness for wiring, the outside of the several conductive wires is not bound and spreads out, resulting in unreliable wiring. In addition, during the actual use of the wire harness of the present invention, after a part of the outer skin is peeled off, the inner conductor and the inner binding part can be placed together on the electrical product or device that needs to be wired, that is, directly act on the inner binding part through fasteners such as screws and bolts. After fixation, the wiring of the wire harness on the electrical product or device can be completed. At the same time, since the inner binding part adopted is flexible and can be bent and shaped, when the wire harness of the present invention is used for threading in a pipe such as a PVC pipe, its bending can be made convenient. At the same time, during the bending operation in a general environment, compared with the existing BV wire, it will not be too hard to bend, and at the same time, it will not be like the BVR wire, which is too soft and difficult to be shaped after bending. Therefore, the wire harness of the present invention can replace the BV wire and the BVR wire for convenient use.

[0007] The present invention is further configured such that the inner binding part is a soft copper tube; by adopting a soft copper tube for the structure of the inner binding part, the convenience of wiring can be ensured. That is, when fasteners such as metal screws or metal bolts on the electrical product or device come into contact with and press the inner binding part, the wiring of the wire harness and the electrical product or device can be completed, and there will be no situation where when using other non-conductive structures, during the wiring process, the inner binding part needs to be pierced when the electrical product or device is wired. In addition, due to the convenient bending characteristic of the soft copper tube, the wire harness of the present invention can be bent conveniently at any angle.

[0008] The present invention is further configured such that the soft copper tube and the several conductive wires are both made of purple copper; through the above setting, it can be avoided that when the existing wire harness adopts an outer purple copper structure and an inner layer of brass or aluminum for cost savings, the produced wire harness will be too hard, thereby affecting the overall softness and hardness of the wire harness. This also further ensures the convenience of the wire harness of the present invention during the bending process at any angle and the reliability of the design.

[0009] The present utility model is further configured such that the thickness of the inner wall of the inner restraint part varies with the cross-sectional area of the wire harness; the minimum thickness of the inner wall of the inner restraint part ≥ 10 filaments; the cross-sectional areas of the wire harness are 12mm, 1.52mm, 2.52mm, 4 2 mm, 62mm, 10 2 mm or 162mm.

[0010] Through the above settings, manufacturers can use inner restraint parts with different wall thicknesses according to the required specifications of the wire harness, that is, to avoid the inner restraint part cracking during the bending process due to inappropriate wall thickness, or the inappropriate softness or hardness of the wire harness. In addition, for wire harnesses of the same specification, the softness or hardness of the wire harness can also be adjusted by adjusting the wall thickness of the inner restraint part.

[0011] The present utility model is further configured such that the outer surface of the soft copper tube is plated with silver or zinc.

[0012] Through the above settings, the anti-corrosion, oxidation resistance, and chemical stability of the soft copper tube can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 is a schematic structural diagram of the wire harness in a specific embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] As Figure 1 shown, a specific embodiment of the present utility model is an easily bendable and easily connectable wire harness, including an outer skin 1, an inner conductor, and a flexible and bendable and shapeable inner restraint part 2. The inner conductor includes a plurality of conductive wires a, and the plurality of conductive wires a respectively pass through the inside of the inner restraint part 2, and the plurality of conductive wires a are in contact with each other and fill the inside of the inner restraint part 2. The outer skin 1 is wrapped outside the inner restraint part 2, and a tight connection is formed between the outer skin 1, the inner restraint part 2, and the plurality of conductive wires a.

[0015] By setting the inner conductor of the wire harness to several conductive wires a, the conductive wires a inside the wire harness, that is, the wire cores, can be of a structure that is convenient to bend. The design of passing several conductive wires a through the inside of the inner binding part 2 respectively, and making the several conductive wires a contact each other and fill the internal structure of the inner binding part 2 can, when the inner conductor adopts the structure of several conductive wires a, through the action of the inner binding part 2, bind the outside of the conductive wires a. That is, the entire rolled wire harness involves the inner binding part 2, thus avoiding the situation where, during the wiring stage, when fasteners such as screws and bolts act on the wire cores of the wire harness for wiring, the outside of the several conductive wires a is not bound, resulting in dispersion and unreliable wiring. In addition, during the actual use of the wire harness involved in the present utility model, after a part of the outer skin 1 is peeled off, the inner conductor and the inner binding part 2 can be placed together on the electrical product or device that needs to be wired, that is, directly act on the inner binding part 2 through fasteners such as screws and bolts. After fixation, the wiring of the wire harness on the electrical product or device can be completed. At the same time, since the adopted inner binding part 2 is of a flexible and bendable and shapeable structure, when the wire harness involved in the present utility model is used for threading in pipes such as PVC pipes, its bending can be made convenient. At the same time, during the bending operation in a general environment, compared with the existing BV wire, it will not be too hard to bend, and at the same time, it will not be similar to the BVR wire, which is too soft and difficult to shape after bending. Therefore, the wire harness involved in the present utility model can replace the BV wire and the BVR wire for convenient use.

[0016] The above-mentioned inner binding part 2 is a soft copper tube. The soft copper tube and several conductive wires a are both made of purple copper, which is a preferred method. In addition, the outside of the soft copper tube can be plated with silver or zinc according to the use requirements.

[0017] The thickness of the inner wall of the above-mentioned inner binding part 2 changes with the size of the cross-sectional area of the wire harness; the minimum thickness of the inner wall of the inner binding part 2 ≥ 10 silk; the cross-sectional area of the wire harness is 12mm, 1.52mm, 2.52mm, 4 2 mm, 62mm, 10 2 mm or 162mm.
