Description

Technical Field

[0001] This utility model relates to the field of robot joints, and in particular to a small floating quick-connect connector for humanoid robot joints. Background Technology

[0002] Humanoid robots are a cutting-edge and rapidly developing field of technology. Connectors are needed at the joints of humanoid robots. Currently, these connectors are rectangular hard-plug structures, which have several drawbacks: First, the rectangular hard-plug structure has a small floating distance (±1.7mm in the XY direction) and lacks a post-mating centering function, making the product prone to misalignment. Misalignment increases contact resistance and damages the contact components, and long-term use of flat plugs shortens the product's lifespan. Second, the rectangular hard-plug structure results in complex product structures and larger dimensions, making assembly difficult, complex processes, and increasing manual labor time.
