[0005] In view of the problems existing in the existing connecting devices for supplying power to electrical equipment, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a connecting device for supplying power to electrical equipment. When the socket and the plug are inserted into the interface, half of the ball enters the limiting groove, and the limiting ring will limit the ball under the drive of the spring, so that half of it is always located in the limiting hole, thereby causing the socket and the plug to be fixedly connected. By screwing the moving ring with the socket, the position of the moving ring can be adjusted, thereby driving the spring to move towards the limiting ring, thereby improving the elasticity of the spring, preventing the elasticity from decreasing after the spring is used for a long time, and being unable to drive the limiting ring to limit the ball, resulting in the loosening or falling off of the socket and the plug.

[0025] The present utility model provides the following technical solution: A connection device for supplying power to an electrical device. During use, it prevents the spring from having a reduced elasticity after a long time of use, being unable to drive the limit ring to limit the ball, resulting in loosening or detachment of the socket and the plug;

[0026] Figures 1-4 Shown is a structural diagram of the first implementation manner of a connection device for supplying power to an electrical device according to the present utility model. Please refer to Figures 1-4, A connecting device for powering an electrical device according to this embodiment, its main body part includes a connector assembly 100, a limiting assembly 200, and a plugging assembly 300;

[0027] The connector assembly 100 includes a socket 110. There is a thread 120 on the outer wall of the socket 110. There is a ball 130 in front of the thread 120. There is an insulating plate 140 in front of the ball 130. There is a connecting column 150 in the inner cavity of the socket 110. There is an insertion opening 160 on the connecting column 150. The bottom of the ball 130 is located in the inner cavity of the limiting hole 320 and is slidably connected to the limiting hole 320. The insulating plate 140 is located on one side of the insulating cover 330 and closes the opening of the insulating cover 330. The socket 110 is used to cooperate with the plug 310 for use to realize the connection between the electrical device and the power supply. The thread 120 is used to realize the screw connection between the moving ring 210 and the outer wall of the socket 110. The ball 130 is used to limit the socket 110 and the plug 310. The insulating plate 140 is used to limit the limiting ring 230 and at the same time close the insulating cover 330. The connecting column 150 is used to open the insertion opening 160. The insertion opening 160 is used to connect with the insertion rod provided on the plug 310;

[0028] The limiting assembly 200 and the plugging assembly 300 are connected to the connector assembly 100. The limiting assembly 200 includes a moving ring 210. One end of the moving ring 210 is connected with a spring 220. The other end of the spring 220 is connected with a limiting ring 230. The moving ring 210 is screwed to the outer wall of the socket 110. The limiting assembly 200 is used to fix the connector assembly 100 and the plug 310 assembly to prevent them from falling off. The moving ring 210 is used to drive and carry the spring 220. The spring 220 is used to drive the limiting ring 230 to reset through its own elasticity. The limiting ring 230 is used to reset the ball 130. When it is necessary to separate the socket 110 from the plug 310, it is necessary to move the limiting ring 230 in the direction of the spring 220 to make the ball 130 in a movable state;

[0029] The plugging assembly 300 includes a plug 310. There are a limiting hole 320 and an insulating cover 330 installed on the plug 310. The plug 310 is plugged into the socket 110. The plugging assembly 300 is used to connect the connector assembly 100 to realize the connection between the electrical device and the power supply. The limiting hole 320 is used to limit the ball 130. The insulating cover 330 is used to cooperate with the insulating plate 140 to close the connection part between the socket 110 and the plug 310;

[0030] Combined Figures 1-4, A connection device for powering an electrical device according to this embodiment has the following specific working principle. When the socket 110 and the plug 310 are inserted into the interface 160, half of the ball 130 enters the limit groove. Driven by the spring 220, the limit ring 230 limits the ball 130 so that it is always half located in the limit hole 320, thus fixing the connection between the socket 110 and the plug 310. By screwing the moving ring 210 with the socket 110, the position of the moving ring 210 can be adjusted, which can drive the spring 220 to move towards the limit ring 230, thereby improving the elasticity of the spring 220 and preventing the elasticity of the spring 220 from decreasing after long-term use, so that the limit ring 230 cannot drive the ball 130 for limiting, resulting in loosening or falling off of the socket 110 and the plug 310.

[0031] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present utility model can be combined with each other in any way.
