Abstract
The utility model provides a twin-cable joint sealing structure, belonging of the technical field of pumps. The utility model solves the problems that if the sheath of cables is broken, water enters a junction box along core wires of the cables, which causes reduction in insulation resistance of the motor or damage of the motor. The twin-cable joint sealing structure comprises a sealing gasket body. A power cable and a control cable pass through the sealing gasket body. The sealing gasket body is provided with a fixing structure for fixing the sealing gasket body to the junction box. A first seal is arranged between the sealing gasket body and the power cable, and a second seal is arranged between the sealing gasket body and the control cable. The twin-cable joint sealing structure provided by the utility model has many advantages.
