ELECTRIC MOTOR WITH WATERTIGHT CONSTRUCTION

摘要

In order to produce a moisture-proof join, which is simple in design and easy to assemble, between the motor housing (1) and the bearing plate (5) with the electrical leads (6, 7) coming out through it, the invention calls for the leads (6, 7) to be moulded in an insulating-material lead-in (2) inserted in an opening at one end of the bearing plate (5) and for a sealing ring (3) to be moulded integrally with the insulating-material lead-in (2). Together with the lead-in (2), the sealing ring (3) is injection moulded on a brush plate (4) so that it can be pre-positioned and, when the motor is assembled, can be inserted between the motor casing (1) and the bearing plate (5) to form a seal. The brush plate (4) is mounted, together with the lead-in (2) and the sealing ring (3) in the bearing plate (5) as a pre-assembled component.
