  • Patent number: 5036583
    Abstract: A contact pin - contact bushing unit comprises a contact pin (3), having two spring-mounted, parallel legs (6) bordering an elongated hole formed by punching. The legs are employed for insertion into the opening of a circuit board. The legs (6) terminate in a shoulder (7) which serves to demarcate the insertion path. The contact bushing is formed by a contact spring bushing (2) with several contact springs (8). The contact springs extend roughly from the area of a clamping shoulder (8), which determines the fixture point of one of their ends, at a distance from the bushing axis to the area of the front pin insertion hole (13). In an intermediate area of the contact bushing, the contact springs display the shortest distance from the bushing axis. The shoulder bordering the contact pin insertion path is formed by the indicated clamping shoulder (7) of the contact spring bushing (2).
