1. Technical Field
The present disclosure relates to a rotatable connector that electrically connects wires together.
2. Description of Related Art
A conventional rotating connector includes a first rotating part, a second rotating part, and a control unit for controlling the second rotating part to rotate relative to the first rotating part. The control unit is electrically connected to the two rotating parts with wires. However, when the second rotating part rotates relative to the first rotating part, the wires can be easily broken if twisted. Thus, the rotating connector is inconvenient in use.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiments of the present disclosure are now described in detail, with reference to the accompanying drawings.

The second rotating member 20 includes a third surface 21 opposing the first rotating member 10 and an opposite fourth surface 22. The third surface 21 forms three latching bodies 23, and the fourth surface 22 forms three second pins 25 thereon. The third surface 23 further mounts three second conducting layers 24 respectively contacting with one of the three second pins 25. The first pins 13 and the second pins 25 are made of electrical conductive material. The latching bodies 23 are shaped to match into the latching grooves 16 of the first rotating member 10. In the embodiment, the latching grooves 16 and the latching bodies 23 are coaxial to each other, and the cross-sections of the latching grooves 16 and the latching bodies 23 are substantially matchstick shaped.
The latching bodies 23 are fit into the latching grooves 16, and thus the second rotating member 20 is rotatably connected to the first rotating member 10. The fixing bodies 14 and the latching bodies 23 cooperatively define three isolated cavities 30. The rotatable connector 1 further includes a number of electrical conductive materials filled in the cavities 30.
When in use, the wires 2 that are respectively fixed to the first pins 13 and second pins 25 can be electrically connected by the electrical conductive materials. When the first rotating member 10 rotates relative to the second rotating member 20, the wires 2 will not be twisted.
While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
