[0020] The present application is further described in detail below in conjunction with the accompanying drawings.
[0021] In order to more clearly understand the technical solution provided by the embodiments of the present application, a brief introduction is first given to the existing home and store dedicated power connection cables and their usage scenarios.
[0022] The wires inside the power connection cables for home appliances are generally formed by twisting multiple strands of fine conductive wires. When the power connection cables are bent too much and too much and are subjected to multiple bends, the fine conductive wires may break.
[0023] The power cables for household appliances are often bent during use, and the bending occurs frequently and at different locations, which significantly increases the possibility of wire breakage inside the power cables, which increases the resistance of the power cables and increases the loss of electrical energy during transmission.
[0024] In order to solve the above technical problems, refer to Figure 1 and Figure 2 The embodiment of the present application provides an energy-saving power connection line for household appliances, including an insulating jacket 11 and a wire 12 arranged inside the insulating jacket 11, an insulating layer is arranged on the outside of the wire 12, and a flexible limiter 21 is also arranged inside the insulating jacket 11. The shape of the flexible limiter 21 is adjustable, and the flexible limiter 21 has a plurality of protrusions 22. The plurality of protrusions 22 are linearly arranged at equal intervals on the flexible limiter 21, and a gap 23 is provided between two adjacent protrusions 22. The plurality of wires 12 are wrapped around the outside of the flexible limiter 21. When the flexible limiter 21 is bent, the protrusions 22 at the bent portion of the flexible limiter 21 are close to each other. When the protrusions 22 at the bent portion of the flexible limiter 21 contact each other, the protrusions 22 provide a force to each other to prevent the protrusions 22 from getting closer.
[0025] The following is a further description based on specific usage scenarios.
[0026] When in use, the power connection line provided in the embodiment of the present application is used in the same way as the power connection line in the prior art. When the power connection line bends during use, the flexible limiter 21 whose shape is adjustable will also bend. As the bending amplitude of the power connection line increases and the bending angle decreases, the protrusions 22 on the flexible limiter 21 will approach each other, causing the gap 23 between two adjacent protrusions 22 to shrink until the two adjacent protrusions 22 are in contact with each other.
[0027] Since the protrusion 22 is fixed on the flexible limiter 21, when the flexible limiter 21 is bent so that the protrusions 22 of the bent part are close to each other and contact each other, the contact between the protrusions 22 and the protrusions 22 will generate a force to limit the shape and position between the protrusions 22 and the protrusions 22, thereby limiting the bending angle of the flexible limiter 21. The flexible limiter 21 is arranged in the middle of the inner side of the insulating jacket 11, and a plurality of wires 12 are all wrapped around the outer side of the flexible limiter 21, that is, the flexible limiter 21 can limit the bending angle of the wire 12, thereby reducing the probability of the conductive wire inside the wire 12 breaking due to the excessive bending angle of the wire 12, reducing the loss of the power connection line when transmitting current, and improving the energy-saving performance of the power connection line.
[0028] In general, the embodiment of the present application is to set a flexible limiter inside the power connection line that can limit the bending range of the power connection line, thereby limiting the bending angle of the wire, reducing the probability of the conductive wire inside the wire 12 breaking due to excessive bending angle, reducing the loss of the power connection line when transmitting current, and improving the energy-saving performance of the power connection line.
[0029] In some possible implementations of the embodiments of the present application, the protrusions 22 on the flexible limit member 21 have several groups, and the same group of protrusions 22 has several protrusions. Several protrusions 22 in the same group are linearly arranged at equal intervals along the central axis of the flexible limit member 21. Several groups of protrusions 22 are arranged in a circular array on the flexible limit member 21. The coordinated setting of several groups of protrusions 22 enables the power connection line to limit more bending, that is, under the coordinated setting of several groups of protrusions 22, no matter in which direction the power connection line bends, there is always one or more groups of protrusions 22 that can limit the bending angle in that direction, which significantly improves the scope of application of the power connection line.
[0030] In the embodiment of the present application, a protrusion 22 is provided inside the flexible limiting member 21. During specific manufacturing, a curling and bonding method can be adopted to support the ring-shaped flexible limiting member 21 having the protrusion 22 inside.
[0031] In some possible implementations of the embodiments of the present application, the width of the protrusion 22 gradually decreases in the direction from the connection point with the flexible limit member 21 to the end of the protrusion 22, so that when the flexible limit member 21 is bent, the protrusions 22 of the bent part of the flexible limit member 21 are close to each other, and the sides where two adjacent protrusions 22 are close to each other are both inclined surfaces, so that the contact area between the two adjacent protrusions 22 is larger. In this way, as the flexible limit member 21 bends, the contact pressure between the protrusions 22 of the bent part is significantly reduced, thereby improving the bending resistance of the flexible limit member 21 after reaching the bending limit, reducing the probability of the conductive wire inside the wire 12 breaking due to the excessive bending angle, reducing the loss of the power connection line when transmitting current, and improving the energy-saving performance of the power connection line.
[0032] In some possible implementations of the embodiments of the present application, when the cross-section of the flexible limiter 21 is parallel to the end face of the flexible wire limiter, the cross-sectional shape of the flexible limiter 21 is annular, and a plurality of protrusions 22 are located on the inner side of the flexible limiter 21. The protrusions 22 do not interfere with the wire 12 on the outer side of the flexible limiter 21.
[0033] Reference Figure 3As a feasible specific implementation method of the embodiment of the present application, an isolation membrane 31 is provided on the outer side of the flexible limiter 21, and the plurality of wires 12 are closely attached to the isolation membrane 31. The flexible limiter 21 and the plurality of wires 12 can slide relative to the isolation membrane 31. In this way, when the power connection line is bent, the wires 12 and the flexible limiter 21 are bent synchronously. After the isolation membrane 31 is provided, the friction between the flexible limiter 21 and the plurality of wires 12 can be reduced, further reducing the probability of the conductive wire inside the wire 12 breaking, reducing the loss of the power connection line when transmitting current, and improving the energy-saving performance of the power connection line.
[0034] As a feasible specific implementation method of the embodiment of the present application, a plurality of stress ribs 24 are further provided on the outer side of the flexible limiter 21, and a plurality of conductors 12 are separated by the plurality of stress ribs 24. The stress ribs 24 can be integrally formed with the flexible limiter 21. When the flexible limiter 21 is bent, it is pulled by the stress ribs 24. Under the condition of the same force applied to the power connector for bending, the flexible limiter 21 will have a smaller bending angle, thereby improving the bending resistance of the flexible limiter 21 after reaching the bending limit, reducing the probability of the conductive wire inside the conductor 12 breaking due to excessive bending angle, reducing the loss of the power connector when transmitting current, and improving the energy-saving performance of the power connector.
[0035] A plurality of conductors 12 are separated by a plurality of stress ribs 24. From the perspective of the end cross-section of the power connection line, there is a stress rib 24 on both sides of each conductor 12. In this way, when the power connection line is bent, the entanglement between the conductors 12 can be reduced, further reducing the probability of the conductive wire inside the conductor 12 breaking, reducing the loss of the power connection line when transmitting current, and improving the energy-saving performance of the power connection line.
[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
