Abstract
Electrical lines for two axially located housings are molded into an inelastic carrier and covered at both faces of the carrier. A seal is injection-molded onto the inelastic carrier. In one implementation in which the carrier is disposed between a commutator housing and a gear housing, the inelastic carrier engages a brush holder that is inserted into one housing of the commutator motor. The design enables the electrical lines to pass into the interior of two axially located housings in a simple manner, while guaranteeing a reliable moisture seal between the housings.
