Abstract

The invention discloses an assembled rotational conductive module and belongs to the technical field of modular products. The assembled rotational conductive module comprises a structure module, a first PCB, a second PCB and a hinge assembly, wherein a buckle is clamped into a buckle hole in an installation condition; the first PCB and the second PCB sleeve a guide post separately; a first conductive needle is propped against a first conductive channel; a second conductive needle is propped against a second conductive channel; the first PCB is clamped on the surface of the structure module; the second PCB is clamped into a clamping groove; and a wire is connected with an interface of the second PCB. When the structure module of the assembled rotational conductive module and the hinge assembly rotate relatively, the conductive needles can be always propped against the corresponding conductive channels, thereby achieving conductive transmission at an arbitrary angle. The conductive needles and the corresponding conductive channels are connected in a sliding manner, thereby overcoming the problems that an internal wire of a rotating shaft is wound and is easily broken in the prior art. The hinge assembly can rotate back and forth in a hinge plane, and furthermore, the structure module can freely rotate around the guide post, so that the assembled rotational conductive module is great in degree of freedom, and stable conduction can be achieved while multi-angle structure connection is achieved.
