Circuit board and contact arrangement for control systems - provides reliable connecting via spring contacts bearing upon underside of board inserted and retained under lugs

摘要

The circuit board (1) is held and secured in the housing trough (6) by means of supports (3, 3a), resilient catches (4, 4a) and lugs (5). When the board (1) is pushed under the lugs (5) its contact surfaces (10) are equally overlapped by those of spring contacts (9). The trough (6) has recesses (7) for removable connector mouldings (8, 8a) on one or more sides, with wire connection terminals (11) in individual chambers of each moulding which are suited to the contact shape. USE/ADVANTAGE - Esp. for electronic modular control systms, secure contacts between board faces and line connectors can be made easily and without screws.
