Description

Technical Field

[0001] This utility model relates to the field of LED lighting connector technology, and in particular to a quick connection structure based on a coaxial audio plug. Background Technology

[0002] With the rapid development of the LED industry, especially full-color LEDs and the DMX512 protocol, multiple LED lights can be efficiently controlled via serial communication. This protocol, through precise lighting control, can create stunning visual effects. Currently, multiple LED lights (or light strips) are typically fixed in a location. These LEDs are usually full-color LEDs, and dynamic lighting effects are achieved by controlling the LED's on / off rhythm and color changes. This is a case of stationary lights or light strips but dynamic lighting. Therefore, those skilled in the art have proposed designing a scheme that can drive the lights themselves to change angles, so that when multiple light arrays are arranged, the movement of the lights and the changes in lighting can be combined to produce more diverse visual lighting effects. For existing technologies, linear displacement or circumferential rotation of the lights is relatively easy to achieve. However, for a servo motor to drive an electrically connected light fixture to rotate 360 ​​degrees, it is necessary to overcome the challenges of electrical connections in the connection structure and the connection of the motor shaft, and to prevent the connecting wires from twisting when the light fixture is rotated. Utility Model Content

[0003] In view of this, this utility model proposes a quick connection structure based on a coaxial audio plug, which enables LED lights to be quickly connected to the motor shaft, and also enables electrical signal connection. When the motor shaft drives the LED lights to rotate, the connecting wires will not be twisted.

[0004] The technical solution disclosed in this utility model is a quick connection structure based on a coaxial audio plug, including a motor shaft, a slip ring socket, a connector, and a coaxial audio plug. The motor shaft is a hollow shaft. The front end of the slip ring socket is a plug interface, and the rear end is provided with a connection terminal. The slip ring socket is tightly fitted into the front end of the motor shaft, and a signal wire is inserted into the motor shaft and connected to the connection terminal.

The coaxial audio plug is disposed in the through hole. When the lower end of the through hole of the connector body is inserted into the front end of the motor shaft, the coaxial audio plug is inserted into the slip ring socket, and the connector body is fixedly connected to the motor shaft.

[0005] Furthermore, one end of the coaxial audio plug is a first 2.5mm male connector, and the other end is a lamp connector for plugging into an LED lamp. The lamp connector is electrically connected to the first 2.5mm male connector.

[0007] Furthermore, a raised edge is provided at the connection between the first 2.5mm male end and the lamp connection end, and a stepped hole is provided at the upper end of the through hole. The raised edge is fastened and embedded in the stepped hole, and the first 2.5mm male end and the through hole are coaxially arranged.

[0008] Furthermore, the front end side wall of the motor shaft is provided with a cut surface, and the inner wall of the through hole of the connecting seat is provided with a straight surface that matches the cut surface.

[0009] Furthermore, a groove is provided circumferentially on the side wall near the front end of the motor shaft.

[0011] The beneficial effects of this utility model are as follows: The quick-connect structure based on a coaxial audio plug, designed and mounted on the motor shaft, uses the front end of the motor shaft as both the fixed end of the connecting base and the electrical connection end with the LED light fixture. A hollow shaft is used to connect the electrical signal wire, which is then connected to a slip ring socket. The coaxial audio plug inside the connecting base is inserted into the slip ring socket. The LED light fixture is fixed on the connecting base. The motor shaft drives the connecting base and the LED light fixture to rotate. The electrical signal wire connected through the slip ring socket will not become twisted as the motor shaft rotates. The LED light fixture is plugged into and fixed in the connecting slot of the connecting base, and then the connecting base is quickly plugged into the front end of the motor shaft through its through-hole, achieving a plug-and-play quick connection. The connecting base and the motor shaft are then locked together.

[0020] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.

[0021] Please refer to Figures 1 to 5 This technical solution provides a quick connection structure based on a coaxial audio plug. This connection structure enables LED lamps to be quickly connected and fixed on the motor shaft 1, allowing the LED lamps to be driven to rotate by the motor. At the same time, electrical signal transmission wires are arranged inside the motor shaft 1 to transmit the power and control signals of the LED lamps.

[0022] The quick-connect structure of this solution includes a motor shaft 1, a slip ring socket 2, a connector, and a coaxial audio plug 4. The motor shaft 1 is a hollow shaft. The front end of the slip ring socket 2 is a plug interface 201, and the rear end is provided with a connection terminal 202. The slip ring socket 2 is tightly fitted into the front end of the motor shaft 1. A signal wire is inserted into the motor shaft 1 and connected to the connection terminal 202. The bottom of the connector 3 is a connector body 301. The connector body 301 has a connection slot 302 for connecting LED lights. The connector body 301 has a through hole 303 that extends to the bottom of the slot 302. The coaxial audio plug 4 is disposed in the through hole 303.

[0023] As a preferred embodiment, one end of the coaxial audio plug 4 is a first 2.5mm male connector 401, and the other end is a lamp connector 402 for plugging into LED lamps. The lamp connector 402 is electrically connected to the first 2.5mm male connector 401.

[0024] As a preferred embodiment of the lamp connector 402, the lamp connector 402 is connected to the LED lamp circuit by a connecting wire; or it is a second 2.5mm male connector, corresponding to the LED lamp equipped with a 2.5mm audio jack; or it is a Micro USB male connector, corresponding to the LED lamp equipped with a Micro USB female connector; or it is a Type-C male connector, corresponding to the LED lamp equipped with a Type-C female connector.

[0028] Furthermore, the connecting slot 302 on the connecting seat 3 is a C-shaped slot with a C-shaped cross-section. Connecting holes are provided on opposite sides of the C-shaped slot for connecting screws or C-shaped fasteners to secure the LED light fixture. In addition, the connecting slot 302 can be designed according to the specific shape of the light fixture.

[0029] This technical solution combines a coaxial audio plug 4 as a quick-connect connector to the slip ring socket 2, which can transmit electrical signals while ensuring that the electrical signal wires inside the motor shaft 1 do not become twisted. The slip ring socket 2 includes an outer rotating part and an inner stationary part (see reference).
