Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the above-described subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0015] See Figures 1 to 6 The present invention provides a stepped rotary electrical connector, comprising: The plug 1 includes a plug housing 11 and a first insulator 12. The plug housing 11 is fixed to the outer wall of the first insulator 12, and the tail end of the first insulator 12 is connected to the first cable 15. The front end of the first insulator 12 is provided with a stepped male connector 121, which includes several steps. Each step is provided with a conductive strip 13. The first insulator 12 is also provided with a terminal 14. The conductive strip 13 is connected to the terminal 14 by a thread. Each conductive strip 13 is electrically connected to the core wire of the first cable 15 through the terminal 14. The core wire of the first cable 15 has a variety of different colors. Each conductive strip 13 is connected to a core wire of one color. The conductive strip 13, the terminal 14 and the first insulator 12 are formed into an integral structure by embedding and molding to improve structural strength and increase processing efficiency. The socket 2 includes a socket housing 21, with a second cable 23 connected to the tail end of the socket housing 21. The front end of the socket housing 21 has a stepped socket, which contains several levels of socket contacts 22 of different diameters. Adjacent levels of socket contacts 22 and the socket contacts 22 at the opening of the stepped socket are fixed and isolated from the inner wall of the socket housing 21 by a second insulator 24. Each level of socket contact 22 is soldered to a core wire led out from the second cable 23. The core wires led out from the second cable 23 have various colors, with each level of socket contact 22 corresponding to a different color core wire. The socket contacts 22 are segmented. When the stepped male connector 121 is inserted into the stepped socket, the segmented socket contacts 22 are interference-fitted with the outer diameter of the corresponding conductive strip 13. The socket contacts 22 do not require any closing treatment to meet the contact resistance requirements.

[0016] This invention employs a stepped male connector 121 and stepped socket design, along with stepped conductive strips 13 and socket contacts 22. Each conductive strip 13 and socket contact 22 forms a pathway, and multiple conductive strips 13 and socket contacts 22 create multiple isolated pathways, enabling simultaneous transmission of multiple electrical signals. Due to the isolation provided by the first insulator 12 and the second insulator 24, the electrical signals do not interfere with each other, improving the transmission efficiency and stability of the connector. Furthermore, the simultaneous contact or separation of each conductive strip 13 and socket contact 22 allows the connector to be plugged in and unplugged while energized. Additionally, the connector of this invention features a simple structure and low contact resistance.

[0017] The plug 1 and socket 2 of the present invention adopt a direct insertion connection method. The conductive strip 13 and the socket assembly of the same level have the same core wire color. After the plug 1 and socket 2 are connected in place, the conductive strip 13 and the socket assembly of the same level are connected and conductive to realize signal transmission. The plug 1 and socket 2 can rotate 360°.

[0018] In some embodiments, the tail end of the plug housing 11 is threadedly connected to a tail connector 16, which abuts against the tail end of the first insulator 12, and the first cable 15 passes through the tail connector 16 and connects to the terminal block 14. The outer wall of the tail connector 16 is provided with threads for connecting to external devices, so as to realize the connection between the plug housing 11 and external devices.

[0019] In some embodiments, in the plug 1, a first sealing ring 17 is provided between the plug housing 11 and the first insulator 12 to achieve a seal between the plug housing 11 and the first insulator 12; in the socket 2, a second sealing ring 25 is provided on the inner wall of the second insulator 24 between the socket contact 22 at the stepped socket opening and the inner wall of the socket housing 21. After the plug 1 and the socket 2 are mated, the second sealing ring 25 achieves a seal between the plug 1 and the socket 2. At the same time, a sealing wire 26 is provided at the tail of the socket housing 21 to seal the gap between the socket housing 21 and the second cable 23. Through the provision of the first sealing ring 17, the second sealing ring 25, and the sealing wire 26, the connector of the present invention has a waterproof function.

[0020] In some embodiments, the outer wall of the socket housing 21 is provided with a third sealing ring 27 and a locking pin 28 to achieve the installation positioning and sealing requirements between the socket housing 21 and the device.

[0021] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
