Abstract
A robot arm joint, a connector and a robot arm are disclosed. The robot arm joint has a joint body and a joint wire assembly. The joint body includes a fixing end and a transmission end. The joint wire assembly is arranged in the joint body and extends on a preset connection path. The preset connection path includes a straight path. The joint wire assembly includes a torsion section connected to the transmission end and a fixed section connected to the fixing end. When the transmission end rotates, the torsion section is simultaneously driven to twist on the straight path.

A robot arm joint, comprising:
- a joint body, including a fixing end and a transmission end, the fixing end having a fixing end connecting surface, the transmission end having a transmission end connecting surface;
- a motor, fixed in the joint body and configured to output power to the transmission end;
- a fixing end modular contact seat, fixed to the fixing end connecting surface, the fixing end modular contact seat including a plurality of fixing end power contacts and a plurality of fixing end signal contacts;
- the fixing end power contacts and the fixing end signal contacts being exposed on the fixing end connecting surface;
- a transmission end modular contact seat, fixed to the transmission end connecting surface, the transmission end modular contact seat including a plurality of transmission end power contacts and a plurality of transmission end signal contacts;
- the transmission end power contacts and the transmission end signal contacts being exposed on the transmission end connecting surface;
- a joint wire assembly, disposed in the joint body, the joint wire assembly including a plurality of joint wires, the plurality of joint wires extending on a preset connection path, the preset connection path including a straight path, the joint wire assembly including a torsion section and a fixed section, one end of the torsion section being connected to the transmission end modular contact seat, one end of the fixed section being connected to the fixing end modular contact seat;
- wherein when the transmission end rotates, the torsion section is simultaneously driven to twist on the straight path, wherein opposite two ends of the straight path have two retaining members, the torsion section of the joint wire assembly is located between the two retaining members, the fixed section is located between the retaining member away from the transmission end and the fixing end;
- wherein when the transmission end rotates, the fixed section is unable to twist inside the joint body.
