Abstract

The invention discloses an electric coupler for reconnecting motor train units. The electric coupler is characterized in that support assemblies and rotary shafts are respectively arranged on two sides of a shell, the support assemblies are structurally identical to each other, two protecting cover assemblies are respectively mounted on the two sides of the shell and are respectively in running fit with the support assemblies and the rotary shafts, an insulator is mounted at the bottom of the shell, a plurality of contact element mounting holes are formed in the insulator, contact elements are mounted in the contact element mounting holes, a middle cover is mounted on the surface of the insulator, a rubber sealing ring is arranged at the edge of the insulator, a groove is formed in each support assembly, an upper roller is mounted at the upper edge of each groove, a lower roller is mounted at the lower edge of each groove, hinge pins are mounted on the protecting cover assemblies, coil springs and handles are arranged on the hinge pins, the handles are in running fit with the lower rollers, rotary mounting holes which are used for being matched with the rotary shafts are formed in the handles, and barriers are arranged on the coil springs and are in running fit with the upper rollers. The electric coupler has the advantage that the insertion reliability and the transmission reliability are effectively compatible with each other.

Description

technical field [0001] The invention relates to the technical field of multi-train reconnection of multiple trains, in particular to an electric coupler used for reconnection of multiple trains. Background technique [0002] When two EMUs are reconnected, there are a lot of electrical signals between the two trains to ensure that they are connected to each other, so that the signals of the two trains are unified, and electric couplers are needed. The previous electric coupler had a single contact type, using only full-contact connectors or full-pinhole contacts. Full-contact connectors have a wide range of adaptation and high reliability of mating, but the reliability of signal transmission is relatively low. The reliability of signal transmission of full-pinhole contacts is high, but due to high precision requirements for pinhole mating, Therefore, its mating reliability is relatively low. Therefore, the number of signal cores of the electric coupler of the EMU in the pas...
