Multi-pipeline electromagnetic shielding cable for signal transmission

The utility model discloses a multi-pipeline electromagnetic shielding cable for signal transmission. The multi-pipeline electromagnetic shielding cable comprises a cable sleeve, a connector, a butt joint, a locking ring, a linkage plate, a screw rod, an extrusion head and an electromagnetic shielding cushion layer. The beneficial effects of the utility model are that during the connection of the electromagnetic shielding cable, a worker can make the electrode column at one end of the connector and the internal cavity of the butt joint be in limited butt joint, then the linkage plate is rotated to drive the screw rod to be linked, the screw rod drives the extrusion head to be linked, and the cavity with the circular truncated cone-shaped structure in the extrusion head extrudes the locking ring to contract, so that the electromagnetic shielding cable is connected. According to the electromagnetic shielding cable provided by the invention, the locking ring is arranged in the butt joint head, and then the elect
