  • Patent number: 4981440
    Abstract: An electric connector includes two complementary connector members, one of which has spring contacts as contact elements and the other has blade contacts as contact elements, wherein the contact elements are mounted in a row or in several parallel rows on base members. The base members are mounted on frame-like enclosing members of housings which extend parallel to the direction of insertion of the contact elements and which serve for the mutual guidance of the housings during the insertion. In the joined state of the connector members, the spring contacts and the corresponding blade contacts can be placed in contact with each other and out of contact from each other by means of contact slide members which are displaceable along the row or rows of contact elements. The connector members can be positively coupled transversely of the direction of insertion by means of locking slide members.
