  • Patent number: 4394602
    Abstract: An enclosed electrical device (42) includes an electrical circuit (50) having elements (48-68) which lie substantially in and along a plane (115). A member (70) is applied to a one side and a member (85) is applied to another side of the circuit (50) for at least partially enclosing the same. Conductors (48) and (49) of circuit (50) are fixedly penetrated, preferably by pins (74) which are fixedly engaged to enclosure members (70) and (85). Such engagement is advantageously provided by making the pins (74) an integral part of member (70), for example by including pins (74) in a premolded member (70). Such engagement is also advantageously provided by making pin-engaging sockets (94) an integral part of member (85), also for example by including the sockets (94) in a premolded member (85). By a preferred friction fit of pins (74) and sockets (94), the enclosure members (70) and (85 ) and circuit elements (48-68) are sufficiently fixed relative to one another to resist forces applied thereto in service.
