Description

Technical Field

[0001] The utility model relates to the technical field of power transmission, in particular to a cable. Background Art

[0002] In the existing quick power connection structure, the power connection is achieved by conductive needles piercing into the cable to contact the conductive bodies inside the cable. Since power consumption requires a loop, at least two conductive needles are needed to connect with the conductive bodies in two cables. In the prior art, the two cables are arranged side by side, and the corresponding two conductive needles are also arranged side by side, some are arranged vertically. No matter which arrangement method the two conductive needles adopt, the direction of piercing into the cable is fixed to ensure reliable piercing into the cable to contact the conductive body. In the actual use scenario, since the cable layout is fixed, the posture of the cable is fixed. Thus, the direction of the conductive needle piercing into the cable can only be unchanged. Since some electrical facilities (such as point light sources) are combined with the conductive needles, the positional relationship between the electrical facilities and the conductive needles is fixed. After the conductive needles are connected to the power, the positions of the electrical facilities will be fixed. However, in some occasions, the positions of the electrical facilities need to adapt to the usage requirements (such as the irradiation direction of the light source). Therefore, the existing quick power connection structure cannot meet the requirements. In addition, the existing cables are flexible and cannot maintain the stability of the shape. Even if some cables are compounded on some components that can be bent and deformed and can maintain the stability of the deformed shape, restricted by the side-by-side arrangement of the two cables, their deformation is also restricted and cannot be deformed arbitrarily. Summary of the Invention

[0003] The invention object of the utility model is to provide a cable that can overcome one or more of the above-mentioned disadvantages and can be connected to power in any direction around the cable axis.

[0004] The present invention is implemented as follows: It includes an insulator and two or more layers of conductive body layers with the cable axis as the axis arranged inside the insulator. The conductive body layers are separated by the insulator. The insulator is made of a material that will not deform when the conductive needle pierces to form a perforation.

[0005] For a general cable with two or more layers of conductive body layers, such as a cable with a shielding layer, due to the properties of the insulating material used, either the conductive needle is difficult to pierce, or even if the conductive needle pierces, the form of the insulating material will change greatly. In this way, the conductive needle cannot accurately pierce to reach the target conductive body layer, thus affecting the reliability of power connection. Since the shielding layer in the prior art only plays a shielding role and will not be used as a conductive body layer, it will not affect its use efficiency, but it cannot be used in the power transmission and connection occasions with loop performance.

[0006] The insulator uses a material that does not deform when a conductive needle pierces through it to form a perforation, such as an insulating silicone material. The conductive needle can smoothly pierce through the insulating layer, and after piercing, the shape of the insulating layer will not change (for example, it will not become flattened under the drive of the conductive needle), ensuring that under the positioning of the insulating layer by the conductive needle, it can accurately reach the conductive layer and reliably connect to the conductive layer.

[0007] Preferably, a core strip is provided at the axis of the cable. The performance of the core strip is such that after being bent, it can maintain its shape without change.

[0008] Preferably, the material of the core strip is a material with memory properties. For a core strip made of such a material, after being bent, it can maintain the stability of the shape under the condition of unchanged external environmental conditions. When the external environmental conditions change (such as heating), it will return to its original physical state (such as restoring the vertical state again); or, the material of the core strip is an elastic material. For a core strip made of such a material, after being bent, as long as a positioning structure is used for positioning at key nodes, it can maintain the stability of the shape. Once the positioning of the positioning structure is removed, the core strip can restore its original physical form (such as the vertical state).

[0009] During use, first lay out the cable of the present invention according to the design requirements, and perform bending according to the design requirements. Then, extrude the component to make the power-taking conductive needle pierce into the cable. Each conductive needle sequentially pierces into the corresponding conductive layer of the cable and connects to the corresponding conductive layer to take electricity, so that the obtained electric energy is transmitted from the cable through the conductive needle to the corresponding electrical facilities (such as a light source arranged on the extrusion component, or an electrical facility connected to the conductive needle through a wire). The body of the conductive needle is wrapped with an insulator. In this way, while the body of the conductive needle cannot be in contact with the penetrated conductive layer to take electricity, the end connection can be connected to the target conductive layer; since the extrusion component can be connected to the cable around various parts of the cable, the positional relationship between the electrical facility fixedly connected to the extrusion component and the position of the conductive needle can be changed arbitrarily according to requirements, thus effectively enriching the decorative effect.

[0010] Preferably, the cross-section of the core strip is circular.

[0011] By using a core strip with a circular cross-section, the cable can be bent in any direction, thus enriching the bending shape of the cable. Using a core strip with a circular cross-section that can maintain its shape unchanged after bending ensures the smooth completion of the bending shape.

[0012] Compared with the prior art, the present invention has the advantages of being able to take electricity in any direction around the axis of the cable and being easy to perform bending during cable laying. Description of the Drawings

[0017] Now, with reference to the drawings and embodiments, the quick power connection structure of the present invention will be further described in detail:

[0018] Embodiment 1: As Figure 1 、 2 shown, the cable of the present utility model is realized as follows. It includes an insulator 1 and two or more layers (two layers in the embodiment, and of course, it can also be four layers, where two layers are for power transmission and the other two layers are for transmitting control electrical signals) of conductor layers 2 arranged with the cable axis as the axis inside the insulator 1. The conductor layers 2 are separated by the insulator 1. The insulator 1 is made of a material that does not deform while the conductive needle 4 pierces to form a perforation.

[0019] Preferably, a core strip 3 is arranged at the cable axis. The performance of the core strip 3 is such that after being bent, it can maintain its shape without change.

[0020] Preferably, the material of the core strip 3 is a material with memory performance; or, the material of the core strip 3 is an elastic material.

[0021] Preferably, the cross-section of the core strip 3 is circular.

[0022] Preferably, the conductor layer 2 is a woven fabric conductor layer woven with wires. Using a woven fabric conductor layer not only facilitates the conductive needle 4 to pass through between the wires of the woven fabric, reducing the damage to the conductor layer 2 caused when the conductive needle 4 passes through, but also improves the anti-bending performance of the conductor layer 2.

[0023] Preferably, the insulator 1 is insulating silica gel or an insulating woven fabric.

[0024] Embodiment 2, as Figure 3As shown, this embodiment is based on the embodiment 1, and the innermost conductor layer 2 is wrapped on the outer surface of the core strip 3. In this way, it is convenient to manufacture and reduce the manufacturing cost. In this way, the core strip 3 wrapped with the conductor layer 2 can constitute one of the conductor layers 2, and at the same time reduce the cost of the core strip 3 as the conductor layer, because the material that can ensure the shape stability after plasticization, the amount of the core strip 3 is very large, and the common conductive copper wire and aluminum wire have the property of ensuring the shape stability after plasticization, but due to the large amount, the material cost is high. If other plastic materials with the same performance are used, they are often poor conductors. The above structure solves this problem.

[0025] When in use, the cable of the utility model is first laid out according to the design requirements, and then the extruding component 5 allows the conductive needle 4 for collecting electricity to penetrate into the cable, and each conductive needle 4 penetrates into the corresponding conductor layer 2 of the cable in turn, and is connected to the corresponding conductor layer 2 for electricity, so that the obtained electric energy is transmitted from the cable to the corresponding power-using facility (such as a light source arranged on the extruding component, or a power-using facility connected to the conductive needle through a wire) through the conductive needle 4. The body of the conductive needle 4 is wrapped with an insulator, so that the body of the conductive needle 4 cannot contact and connect with the conductor layer 2 passed through, while the end connection point can be connected with the target conductor layer 2; because the extruding component 5 can be connected to the cable at various places around the cable, the position of the power-using facility fixedly connected to the extruding component 5 and the position relationship of the conductive needle 4 can be changed at will according to requirements, thereby effectively enriching the decorative effect.
