Abstract
A strain relief connection between a housing and an electric conductor assembly. The housing is formed of two plastic housing parts (2,20) which meet with each other over a contact surface (47). The electric conductor assembly (42) includes stranded conductors (43) extending through individual plastic jackets (45) which are surrounded by a common insulating sheath (46). The electric conductor assembly (42) passes from the exterior of the housing to the interior thereof, with portions of the plastic jackets (45) arranged over and contacting the contact surface (47) between the two housing parts (2,20) and with the two housing parts (2,20) being heat sealed together with the plastic jackets (45) at the contact surface (47). One (20) of the two housing parts has a collar-shaped attachment (48) inclined with respect to the contact surface (47) in the vicinity of the electric conductor assembly (42) and partially overlapping the sheath (46) and pressing the sheath (46) against the other (2) of the two housing parts. The strain relief connection is especially useful in conjunction with the housing and electric conductor assembly of an electromagnetic valve.
