  • Patent number: 5597332
    Abstract: A solder contact made of a stamped piece of sheet metal with a housing with housing walls and with a movably attached contact position bounded by two contact spring arms for contact with the contact pin, whereby the housing exhibits at least one soldering post insertable through a hole in a printed-circuit board and whereby the contact position bounding the contact spring arms with a bow spring arm support are connected to one of the housing walls and the bow spring arm support extends freely in the housing in an arched shape, so that the contact position bounded by the contact spring arms is arranged to be movable in the direction of the plug axis of and/or perpendicular to it.

  • Patent number: 5295873
    Abstract: Double leaf spring contact with external enclosure spring and a cover in the form of skids which cover stop devices on fork spring arms of the double-leaf spring contact. Fork spring arms converge in the shape of a curve to form a contact element for a counter contact, and stop devices that protrude towards the outside and maintain a certain distance between the converging fork spring arms are arranged in the contact area. An external enclosure spring includes a box-shaped spring arm base that rests on the spring arm base of the double leaf spring contact in a positive and stationary manner, and converging enclosure spring fork arms are connected to the lateral side walls of the spring arm base that press against the fork spring arms of the double leaf spring contact from the outside. Skids cover at least the stop devices of the fork spring arms of the double leaf spring contact and are arranged on an external enclosure spring that rests on the double-leaf contact spring.
