[0018] When the conductive interface needs to be rotated to any angle, the rotating base is rotated, causing the rotating base and the fixed base to rotate relative to each other. This, in turn, causes the fixed PCB board and the rotating PCB board to rotate relative to each other. When the fixed PCB board and the rotating PCB board rotate relative to each other, each contact spring and the two contact slip rings rotate relative to each other. At least one contact spring and one contact slip ring remain in contact and electrically connected, and at least another contact spring and another contact slip ring remain in contact and electrically connected. This ensures that the fixed PCB board and the rotating PCB board maintain electrical connection when they rotate relative to each other, allowing the conductive interface to be rotated to any angle. This improves upon the current conductive interface, which is not easy to achieve arbitrary angle rotation, and where the rotating component can easily affect the wires when the two components rotate relative to each other, leading to interference and wire breakage.

Description
Technical Field
[0001] This application relates to the technical field of electrical rotary connections, and in particular to a conductive interface that can be rotated and adjusted at any angle. Background Technology
[0002] Conductive interfaces are suitable for devices that require stable power or signal transmission between two relatively rotating components, such as robot joints, rotary robotic arms, wind turbine slip ring systems, medical rotating devices, and rotating lamp holders. They are particularly suitable for power and signal transmission between two components of a rotating lamp holder.
[0003] Currently, conductive interfaces are not easy to rotate at any angle. When two relatively rotatable components rotate relative to each other, the rotating component can easily affect the wires, causing interference and potentially leading to wire breakage. Summary of the Invention
[0004] In order to enable the conductive interface to be rotated and adjusted at any angle, this application provides a conductive interface that can be rotated and adjusted at any angle.
[0005] The conductive interface with an adjustable angle that can be rotated arbitrarily provided in this application adopts the following technical solution:
[0006] A conductive interface with adjustable angle by arbitrary rotation includes a fixed base, a rotating base, and a connecting assembly. The rotating base is inserted through the fixed base, and the rotating base and the fixed base can rotate relative to each other. The fixed base is provided with a fixed PCB board, and the rotating base is provided with a rotating PCB board.
[0007] The connection assembly includes at least two contact springs and two contact slip rings. Each contact spring is fixed and electrically connected to a rotating PCB board or a fixed PCB board, and the two contact slip rings are fixed and electrically connected to a fixed PCB board or a rotating PCB board. When the rotating PCB board and the fixed PCB board rotate relative to each other, at least one contact spring abuts against and is electrically connected to one of the contact slip rings, and at least another contact spring abuts against and is electrically connected to the other contact slip ring, so that the fixed PCB board and the rotating PCB board are electrically connected.
[0008] By adopting the above technical solution, when the conductive interface needs to be rotated to any angle, the rotating seat is rotated, causing the rotating seat and the fixed seat to rotate relative to each other, thereby causing the fixed PCB board and the rotating PCB board to rotate relative to each other. When the fixed PCB board and the rotating PCB board rotate relative to each other, each contact spring and the two contact slip rings rotate relative to each other. When each contact spring and the two contact slip rings rotate relative to each other, at least one contact spring and one contact slip ring remain in contact and electrically connected, and at least another contact spring and another contact slip ring remain in contact and electrically connected, so that the fixed PCB board and the rotating PCB board always maintain electrical connection when they rotate relative to each other. This allows the conductive interface to be rotated to any angle, improving the current conductive interface, which is not easy to achieve rotation at any angle. When two relatively rotatable components rotate relative to each other, the rotating components are prone to affecting the wires, causing interference with the wires and leading to wire breakage.
[0009] Optionally, an isolation ring is provided between the fixed PCB board and the rotating PCB board, with at least one of the contact springs located inside the isolation ring and at least another contact spring located outside the isolation ring.
[0010] Optionally, the fixing seat is fixedly provided with a brake pad, and the isolation ring is fixedly provided with at least one fixing post, and each fixing post is fixedly connected to the brake pad.
[0011] Optionally, the isolation ring is fixedly provided with at least two snap-fit blocks, and the fixed PCB board is provided with at least two snap-fit slots, with each snap-fit block passing through and snap-fitting into each snap-fit slot.
[0012] Optionally, the rotating seat is fixedly provided with at least one abutting protrusion, and each abutting protrusion abuts against the side of the fixed PCB board away from the isolation plate.
[0013] Optionally, the fixed PCB board has at least one through-hole, and each of the fixed posts passes through and slides into the through-hole.
[0014] Optionally, the rotating seat has a plurality of adjustment holes, each of which is evenly distributed around the axis of the rotating seat. The fixed seat is slidably fitted with an adjustment block. When the fixed seat and the rotating seat are relatively fixed, the adjustment block passes through any of the adjustment holes. When the adjustment block slides toward the fixed seat until it disengages from each of the adjustment holes, the fixed seat and the rotating seat can rotate relative to each other.
[0015] Optionally, the fixing seat is fixedly provided with a limiting protrusion, and the adjusting block is provided with at least two limiting grooves. When the limiting protrusion passes through and engages with at least one of the limiting grooves, the adjusting block passes through any of the adjusting holes. When the limiting protrusion passes through and engages with at least another limiting groove, the adjusting block disengages from each of the adjusting holes.
[0016] Optionally, the rotating seat includes a seat body and an abutting part, the seat body and the abutting part are fixedly connected, the seat body abuts against one side of the fixed seat facing both sides, and the abutting part abuts against the other side of the fixed seat facing both sides.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] When the conductive interface needs to be rotated to any angle, the rotating base is rotated, causing the rotating base and the fixed base to rotate relative to each other. This, in turn, causes the fixed PCB board and the rotating PCB board to rotate relative to each other. When the fixed PCB board and the rotating PCB board rotate relative to each other, each contact spring and the two contact slip rings rotate relative to each other. At least one contact spring and one contact slip ring remain in contact and electrically connected, and at least another contact spring and another contact slip ring remain in contact and electrically connected. This ensures that the fixed PCB board and the rotating PCB board maintain electrical connection when they rotate relative to each other, allowing the conductive interface to be rotated to any angle. This improves upon the current conductive interface, which is not easy to achieve arbitrary angle rotation, and where the rotating component can easily affect the wires when the two components rotate relative to each other, leading to interference and wire breakage.

[0031] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.
[0032] This application discloses a conductive interface with an adjustable angle that can be rotated arbitrarily. (Refer to...) Figures 1 to 5 A conductive interface with an adjustable angle that can be rotated arbitrarily includes a fixed base 1, a rotating base 2, and a connecting component 3.
[0033] Reference Figure 5 , Figure 6 as well as Figure 7 The fixed seat 1 has a through rotating hole 11 at one end. The rotating seat 2 includes a seat body 21 and an abutment part 22. The seat body 21 and the abutment part 22 are fixedly connected by screws. When the rotating seat 2 is rotatably connected to the fixed seat 1, the seat body 21 passes through and rotates into the rotating hole 11. The seat body 21 abuts against one side of the fixed seat 1 on both sides, and the abutment part 22 abuts against the other side of the fixed seat 1 on both sides, so that the rotating seat 2 and the fixed seat 1 can rotate relative to each other around the axis of the rotating hole 11. In this embodiment, the axis of the rotating hole 11 is set to the vertical direction.
[0034] Reference Figure 5 , Figure 8 as well as Figure 9The fixed base 1 is fixedly equipped with a brake pad 12. When the rotating base 2 rotates relative to the fixed base 1, the brake pad 12 does not easily rotate with the rotating base 2. The fixed base 1 is equipped with an isolation ring 13. Multiple fixing posts 131 are fixedly equipped on one side of the isolation ring 13. Each fixing post 131 is evenly distributed around the axis of the isolation ring 13. Each fixing post 131 is fixedly connected to the brake pad 12 by screws. The fixed base 1 is equipped with a fixed PCB board 14. The fixed PCB board 14 has multiple through sliding holes 141. Each fixing post 131 passes through and slides into each sliding hole. 141. The fixed PCB board 14 has multiple through-hole slots 142. The isolation ring 13 has multiple snap-fit blocks 132 fixedly disposed on the side near the fixed PCB board 14. Each snap-fit block 132 is evenly distributed around the axis of the isolation ring 13. Each snap-fit block 132 passes through and snaps into each snap-fit slot 142. The abutment part 22 has multiple abutment protrusions 221 fixedly disposed on the side near the fixed PCB board 14. Each abutment protrusion 221 is evenly distributed around the axis of the abutment part 22. Each abutment protrusion 221 abuts into the fixed PCB board 14.
[0035] Reference Figure 2 , Figure 5 as well as Figure 7 The rotating base 2 is provided with a rotating PCB board 23. The base body 21 is fixedly provided with a plurality of limiting strips 211. Each limiting strip 211 passes through the rotating PCB board 23 and abuts against the PCB board, so that the rotating PCB board 23 can rotate with the rotating base 2, thereby allowing the rotating PCB board 23 to rotate relative to the fixed PCB board 14. The rotating PCB board 23 and the fixed PCB board 14 are arranged facing each other, and the isolation ring 13 is located between the rotating PCB board 23 and the fixed PCB board 14.
[0036] Reference Figure 2 One end of the base 21 is provided with a connecting thread, which can be used to connect with the lamp holder thread, and can also be used to connect with various screw connectors 24, thereby realizing threaded connection with various lamp holders.
[0037] Reference Figure 7 , Figure 8 as well as Figure 10The base 21 has several adjustment holes 212 on the side near the fixed base 1. The adjustment holes 212 are evenly distributed around the axis of the rotating base 2. The fixed base 1 is slidably fitted with an adjustment block 15 in the vertical direction. When the fixed base 1 and the rotating base 2 are fixed relative to each other, the adjustment block 15 passes through any adjustment hole 212. When the adjustment block 15 slides towards the fixed base 1 until it disengages from each adjustment hole 212, the fixed base 1 and the rotating base 2 can rotate relative to each other. The fixed base 1 is fixedly provided with a limiting protrusion 16. The limiting protrusion 16 is elastic. The adjustment block 15 has two limiting grooves 151. When the limiting protrusion 16 passes through and is engaged with one limiting groove 151, the adjustment block 15 passes through any adjustment hole 212. When the limiting protrusion 16 passes through and is engaged with the other limiting groove 151, the adjustment block 15 disengages from each adjustment hole 212.
[0038] Reference Figure 11 The connecting component 3 includes multiple contact springs 31 and two contact slip rings 32. Each contact spring 31 is fixed and electrically connected to the side of the rotating PCB board 23 near the fixed PCB board 14. Some contact springs 31 are located inside the isolation ring 13 and are designated as first contact springs 31. These first contact springs 31 are evenly distributed circumferentially around the axis of the rotating PCB board 23. The other part of the contact springs 31 are located outside the isolation ring 13 and are designated as second contact springs 31. These second contact springs 31 are also evenly distributed circumferentially around the axis of the rotating PCB board 23. The first and second contact springs 31 are isolated by the isolation ring 13, thus preventing short circuits between them. Both contact slip rings 32 are fixed and electrically connected to the side of the fixed PCB board 14 near the rotating PCB board 23. Yes, the contact slip ring 32 is electroplated onto one side of the rotating PCB board 23 through an electroplating process, thereby achieving a fixed connection between the contact slip ring 32 and the rotating PCB board 23. The two contact slip rings 32 are coaxially arranged, with one contact slip ring 32 located inside the isolation ring 13 as the first contact slip ring 32, and the other contact slip ring 32 located outside the isolation ring 13 as the second contact slider. Each first contact spring 31 and the first contact slip ring 32 abut and are electrically connected, so that when the rotating PCB board 23 drives each first contact spring 31 to rotate, each first contact spring 31 always maintains an electrical connection with the first contact slip ring 32. Each second contact spring 31 and the second contact slip ring 32 abut and are electrically connected, so that when the rotating PCB board 23 drives each second contact spring 31 to rotate, each second contact spring 31 always maintains an electrical connection with the second contact slip ring 32.
[0039] The implementation principle of the conductive interface with arbitrarily adjustable angle according to the embodiments of this application is as follows: When the conductive interface needs to be rotated to any angle, the rotating seat 2 is rotated, so that the rotating seat 2 and the fixed seat 1 rotate relative to each other, thereby causing the fixed PCB board 14 and the rotating PCB board 23 to rotate relative to each other. When the fixed PCB board 14 and the rotating PCB board 23 rotate relative to each other, each contact spring 31 and the two contact slip rings 32 rotate relative to each other. When each contact spring 31 and the two contact slip rings 32 rotate relative to each other, at least one contact spring 31 and one contact slip ring 32 remain in contact and electrically connected, and at least another contact spring 31 and another contact slip ring 32 remain in contact and electrically connected, so that the fixed PCB board 14 and the rotating PCB board 23 always maintain electrical connection when rotating relative to each other, thereby enabling the conductive interface to be rotated to any angle. This improves the current conductive interface, which is not easy to achieve arbitrary angle rotation. When two relatively rotatable components rotate relative to each other, the rotating components are prone to affecting the wires, causing interference from the wires and leading to wire breakage.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
