Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a quick electrical connection structure. Background Technology

[0002] Existing quick-connection structures achieve power connection by inserting conductive needles into the cable and making contact with the conductors inside. Since electricity requires a circuit, at least two conductive needles are needed to connect to the conductors in two cable strands. In current technology, the two cable strands are arranged side-by-side, and the two conductive needles are correspondingly arranged side-by-side (or sometimes vertically). Regardless of the arrangement, the direction in which the needles penetrate the cable remains fixed to ensure reliable contact with the conductors. However, in practical applications, the cable layout and orientation are fixed, meaning the direction in which the conductive needles penetrate the cable is also fixed. The existing quick-connection structure cannot meet the requirements of some electrical facilities (such as electric light sources) which are integrated with conductive needles. The position of the electrical facility and the position of the conductive needle are fixed. Thus, after the conductive needle is energized, the position of the electrical facility will remain fixed. However, in some cases, the position of the electrical facility needs to be adapted to the usage requirements (such as the illumination direction of the electric light source). In addition, the existing cables are flexible and cannot maintain the stability of their shape. Even if some cables are combined with some flexible and deformable components that can maintain the stability of the deformed shape, their deformation is constrained by the parallel arrangement of the two cables and cannot be deformed at will. Summary of the Invention

[0003] The purpose of this invention is to provide a quick power connection structure that can overcome one or more of the above-mentioned disadvantages and can connect to the power in any direction around the cable axis.

[0004] This invention is implemented as follows: it includes a cable and a quick-connect component connected to the cable. The cable includes an insulator and two or more layers of conductive material arranged within the insulator with the cable axis as the axis. The conductive material is separated by the insulator. The quick-connect component includes conductive pins in number matching the number of conductive material layers and a pressing component that pushes the conductive pins into the cable. Under the action of the pressing component, several conductive pins sequentially pierce into the cable at different positions. The pressing component has a limiting structure to prevent the conductive pins from continuing to pierce into the cable, and to ensure that the electrical contacts at the ends of the conductive pins piercing the cable are respectively connected to the corresponding conductive material layers. The outer surface of the conductive pin body that passes through the conductive material layer is an insulator, ensuring that the electrical contacts at the ends of the conductive pins contact and connect to the target conductive material layer, while the conductive pin body cannot contact and connect to the conductive material layer it has passed through.

[0005] In use, cables are first laid according to design requirements. Then, the extrusion component causes conductive needles to pierce into the cables. Each conductive needle sequentially pierces into the corresponding conductor on the cable and connects to the corresponding conductor, allowing the acquired electrical energy to be transmitted from the cable to the corresponding electrical facilities (such as light sources installed on the extrusion component, or electrical facilities connected to the conductive needles via wires). The body of the conductive needle is wrapped with an insulator, so that the body of the conductive needle cannot come into contact with the conductive layer it passes through, while the end of the conductive needle can connect to the target conductive layer. Since the extrusion component can be connected to the cable at various points, the position of the electrical facilities fixedly connected to the extrusion component and the position of the conductive needles can be changed at will according to requirements, thus effectively enriching the decorative effect.

[0006] Preferably, a first core strip, which is a steel wire rope, is provided at the cable axis. Using a steel wire rope, the cable can be straightened and fixed between two positioning objects (such as two walls) through a fixing component (such as the technology described in patent application CN202110805507.4). Utilizing the tensile strength and lifting capacity of the steel wire rope, electrical facilities (such as point light sources) can be installed on the straightened cable, thus facilitating the laying of power lines and electrical facilities.

[0007] Preferably, a second core strip is provided at the cable axis. This second core strip has the following properties: after bending, it maintains its shape without change. The material of the second core strip is a material with memory properties. Using this material, the core strip, after bending, can maintain its shape stability while keeping external environmental conditions constant. When external environmental conditions change (such as heating), it will return to its original physical state (e.g., return to a vertical position). Alternatively, the material of the second core strip is an elastic material. Using this material, after bending, as long as a positioning structure is used at key nodes, the shape can maintain stability. Once the positioning structure is removed, the second core strip can return to its original physical shape (e.g., a vertical position).

[0008] Preferably, the cross-section of the second core strip is circular.

[0009] By using a core strip with a circular cross-section, the cable can be bent in any direction, thus enriching the bending design of the cable.

[0010] Preferably, the conductive needle body is cylindrical, and the conductive needle tip with electrical contact is conical. In this way, the conductive needle can penetrate the conductive layer, and when the conductive needle tip with electrical contact reaches the target conductive layer, the conical surface of the conductive needle tip with electrical contact can rest against the conductive layer, ensuring reliable electrical contact.

[0011] Compared with existing technologies, this utility model has the advantages of being able to connect to the power source in any direction around the cable axis and being easy to bend and shape during cable laying. Attached Figure Description

Detailed Implementation

[0018] The quick-connection structure of this utility model will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] Example 1: As Figure 1 , 2 As shown in Figure 3, the quick-connect structure of this utility model is implemented as follows: it includes a cable a and a quick-connect component b connected to the cable a. The cable a includes an insulator 1 and two or more (two layers in the embodiment) conductive bodies 2 arranged inside the insulator 1 with the cable axis as the axis. The conductive bodies 2 are separated by the insulator 1. The quick-connect component b includes conductive pins 3 (flat or cylindrical in shape) whose number matches the number of conductive body 2 layers (two in the embodiment). It also includes a pressing component 4 that pushes the conductive pins 3 into the cable a. The pressing component 4 includes a base 402 with a notch 401 that matches the cable a and can be equipped with electrical facilities (such as an electric light source whose power input terminal is fixed on the base 402 and connected to the conductive pins 3). It also includes a pushing component 403 that pushes the cable a into the notch 401. The two conductive pins 3 are fixed to the bottom surface 404 of the notch 401 and are distributed back and forth along the axial direction of the cable a.

[0020] Preferably, the notch 401 is a concave arc shape that matches the shape of the cable a. Using the concave arc shape of the notch 401, the pusher 403 pushes the cable a towards the notch 401, making the cable a tightly adhere to the bottom surface 404 of the notch 401. Because the notch 401 is a concave arc shape that matches the shape of the cable a, the cable a will not deform. This ensures that the end contact 301 of the conductive needle 3 inserted into the cable a makes good contact with the matching conductor 2, preventing the end contact 301 of the conductive needle 3 inserted into the cable a from either failing to reach the matching conductor 2 or passing through the matching conductor 2 without making contact due to deformation of the cable a.

[0021] Preferably, the upper part of the notch 401 has an external thread 405, the pusher 403 is a nut, the cable crosses the notch 401, the pusher 403 is screwed into the upper part of the notch 401, and the two conductive needles 3 are pushed by the pusher 403 of the extrusion member to move the cable a towards the conductive needle 3 and are sequentially inserted into the cable a at different positions of the cable a. The extrusion member 4 is provided with a limiting structure 5, which is a stop surface at the bottom of the external thread. The pusher 403 stops at the stop surface, so that the extrusion member 4 cannot allow the conductive needles 3 to continue to insert into the cable a, and the end contact points 301 of the several conductive needles 3 inserted into the cable a are respectively connected to the corresponding conductive body 2 layer. The outer surface of the body 302 of the conductive needle 3 that passes through the conductive body 2 layer is an insulator, so that the end contact point 301 of the conductive needle 3 contacts and connects to the target conductive body 2 layer, while the body 302 of the conductive needle 3 cannot contact and connect to the conductive body 2 layer it passes through.

[0022] Of course, there are various types of pushers 403 that push cable a into recess 401, including extrusion members connected to base 402 via a bayonet connection structure; or swing members with one end swinging to base 402 and the other end swinging to base 402 via a bayonet connection structure.

[0023] Preferably, the body 302 of the conductive needle 3 is cylindrical, and the electrical contact point 301 at the end of the conductive needle is conical.

[0024] Preferably, a second core strip 6 is provided at the axis of cable a. The second core strip 6 has the following properties: after bending and shaping, it can maintain its shape without change. The material of the second core strip 6 is a material with memory properties. Using this material, after bending and shaping, the second core strip 6 can maintain the stability of its shape while keeping the external environmental conditions unchanged. When the external environmental conditions change (such as heating), it will cause cable a to return to its original physical state (such as returning to a vertical state). Alternatively, the material of the second core strip 6 is an elastic material. Using this material, after bending and shaping, as long as the positioning structure is used at the key node, the stability of the shape can be maintained. Once the positioning structure is removed, the second core strip 6 can cause cable a to return to its original physical shape (such as a vertical state).

[0025] Preferably, the cross-section of the second core strip 6 is circular.

[0026] Preferably, such as Figure 3 , 4 As shown, the conductive needle 3 passing through the conductive body 2 includes a columnar conductive body 303 with an end contact 301, and an insulator 302 wrapping the body of the columnar conductive body 303.

[0027] Example 2, as Figure 4 As shown, this embodiment is based on embodiment 1, with the innermost conductor 2 wrapped around the outer surface of the second core strip 6. This facilitates manufacturing and reduces manufacturing costs. The second core strip 6, wrapped with the conductor 2, can constitute one layer of the conductor 2, while simultaneously reducing the cost of the second core strip 6 as a conductor. This is because the amount of the second core strip 6 used is very large, as it is a material that can maintain shape stability after molding. Common conductive copper and aluminum wires have the property of maintaining shape stability after molding, but due to the large amount used, the material cost is high. If other plastic materials with the same properties are used, they are often poor conductors. The above structure solves this problem.

[0028] Preferably, the conductor 2 is a braided conductor made of wires. Using a braided conductor not only makes it easier for the conductive needle 3 to pass through the wires of the braid, reducing damage to the conductor 2 when the conductive needle 3 passes through, but also improves the bending resistance of the conductor 2.

[0029] Preferably, the insulator 1 is insulating silicone or insulating braided fabric.

[0030] Example 3: As Figure 5 As shown, this embodiment is based on embodiments 1 and 2, with a first core strip 6 provided at the axis of cable a, and the first core strip 6 is a steel wire rope.
