RETENTION SPRING AND SUBSTRATE THEREFOR

摘要

The present invention relates to a spring member (1) for retaining an electrical plug and a substrate (100) for a receptacle (201) for an electrical plug. In order to provide a receptacle for electrical plugs, especially 3.5 mm AV-plugs with circular cross-sections, which provides stable and sufficiently high retention forces, a spring member (1) according to the present invention is designed such that it comprises at least two spring sections (12a, 12b) resiliently deflectable with respect to each other and defining between them a volume (3) for receiving at least a section of the electrical plug in an insertion direction (I) of the spring member (1), wherein at least one of the spring sections (12a, 12b) provides a guiding surface (3a, 3b) slanted with respect to the insertion direction (I) for guiding the plug into an end position (F) of the plug within the volume (3) and a latching organ (31) adapted to interact with the plug in the end position (F) in order to prevent withdrawing the plug from the end position (F) against the insertion direction.
