Abstract: An electrical interconnect system employs electrical connectors in which both the housing (or support) and the contact(s) thereof are hermaphroditic, i.e., without gender limitations. Therefore, two such connectors may interconnect with each other. Contacts are arranged in a header or other housing or support in which at least two contacts, for example, adjacent contacts, respectively face in opposite directions. Bifurcated and trifurcated contacts have contacting portions respective ones of which face in opposite directions and are supported on parallel cantilever arms.

Abstract: An electrical shunt includes a U-shape contact having a unitary body molded directly in a housing into which pin contacts may be inserted for connection to and via the shunt.

Abstract: An electrical shunt includes a U-shape contact having a unitary body molded directly in a housing into which pin contacts may be inserted for connection to and via the shunt.A method of making an electrical shunt formed of an electrically conductive contact having plural contacting portions for connection with respective external members inserted to connection therewith and an electrically non-conductive housing includes molding electrically non-conductive material directly to at least part of such contact to form such housing, whereby such housing and contact form an integral structure, including forming relatively open chamber areas within the housing for exposure therein of such contacting portions, and forming an opening in such housing for insertion therein of respective external members for electrical connection with respective contacting portions.

Abstract: An electrical connector for connection to plural contacts mounted on a printed circuit board, other support or the like, including plural electrical contacts for engaging and electrically connecting with corresponding ones of such plural contacts, a support structure for supporting the electrical contacts, a resilient latch mechanism for maintaining the electrical connector in position with respect to such plural contacts and such printed circuit board and independently of such plural contacts, a keying mechanism to assure correct contact to contact installation and an anti-rotation mechanism cooperative with such printed circuit board to prevent rotation of the electrical connector relative thereto during installation onto such plural contacts. In a preferred embodiment the plural contacts are connected, e.g. by soldering, to the printed circuit board or to circuits thereon or associated therewith, and the anti-rotation mechanism helps to prevent applying torsion forces to such connections.

Abstract: A face mask cut from a sheet of foamed resin material has slits cut near each end shaped to curve inwardly in a U shape. The ends of the mask conform approximately to the U shape of the slits so that the material between the slits and the ends of the mask forms a pair of U-shaped ear loops. The ear loops are bendable in a one-half turn so that the U shapes extend outwardly away from the central portion of the mask for resiliently looping over the ears of the wearer to hold the mask in place.
