Abstract

The invention relates to a liquid-metal high-speed rotation electrical connector. The connector comprises a shell, an output terminal cap, an input terminus cap, an electrical rotor and liquid metal. The output terminal cap and the input terminus cap are arranged on two ends of the shell. The output terminal cap is provided with an output terminal. The input terminus cap is provided with a through hole. The electrical rotor is arranged in the shell. One end of the electrical rotor is provided with an input terminal which passes through the through hole of the input terminus cap. The other end of the electrical rotor, the shell and the output terminal cap form an inner cavity. The liquid metal is arranged in the inner cavity. Compared to the prior art, by using the electrical connector and the method of the invention, the structure is compact, there is no response hysteresis effect, an abrasion amount is small, the structure is simple, processing cost is low, simultaneously magnetofluid sealing is designed, the connector and the method can be applied to extreme environments of dust, underwater and the like, and a response speed, stability, reliability, economical efficiency and a service life of the electrical connector are greatly increased and prolonged.

Description

technical field [0001] The invention relates to a rotary electrical connector, in particular to a liquid metal high-speed rotary electrical connector and a design method thereof. Background technique [0002] A rotary electrical connector is a connector whose input and output ends can rotate around a common axis and can ensure circuit connection. It is usually used in automobile steering devices, deep well drilling rigs, CNC beds and other equipment. In the rotary connector, the most common form is the mechanical structure type, that is, the coaxial arrangement of the fixed outer cylinder and the rotatable body with the inner cylinder, and the ribbon cable is accommodated and wound around these outer cylinders and inner cylinders In the accommodation space divided between the bodies, the rotary circuit connection is realized. Such a rotary connector is used as an electrical connection unit for an airbag inflator and the like mounted on a handle with a limited number of rota...
