The outlet box includes two latch members along the sides which are bow shaped and have grounding surfaces thereon, which latch the outlet box in place to a panel, and simultaneously ground the box to the panel.Type: GrantFiled: February 6, 1990Date of Patent: January 22, 1991Assignee: AMP IncorporatedInventors: Jess B. Ferrill, Randy G. Simmons

Patent number: 4921430Abstract: A connector for electronic parts has a plurality of electronic contacting pieces arranged on a connector body at very narrow spaces and in parallel relation with respect to one another. Each of the electric contacting pieces is provided with an insulation material attached on its outer surface facing an adjacent electric contacting piece, so that the insulation material will act to isolate adjacent electric contacting pieces. The electric contacting pieces are thus planted in the connector body without any other insulating substance than the insulation material disposed between the adjacent electric contacting pieces.Type: GrantFiled: September 13, 1989Date of Patent: May 1, 1990Assignee: Yamaichi Electric Mfg. Co., Ltd.Inventor: Noriyuki Matsuoka

Patent number: 4902235Abstract: A socket for mounting an integrated circuit unit on a printed circuit board comprises a plurality of inserts of a platable electrically insulating material each having an opening and an exterior surface portion. The inserts are mounted in rows in a support body so the openings are accessible from one side of the body and the exterior surface portions are exposed at an opposite side of the body. Electrically conductive layers are provided on the inner surfaces of the insert openings, preferably by electroless plating techniques using the body as a plating mask, to extend to the exterior surface portions of the inserts to be soldered to circuit paths on the printed circuit board at prescribed circuit locations. Contacts are disposed in the insert openings in electrical engagement with the electrically conductive layers therein for resiliently and detachably electrically engaging terminals of integrated circuit units or the like inserted into the openings.Type: GrantFiled: July 20, 1988Date of Patent: February 20, 1990Assignee: Texas Instruments IncorporatedInventor: Takashi Tonooka

Patent number: 4806111Abstract: A connector structure comprising an electrically conductive plate having a plurality of through holes formed therein, an electrically insulated film formed on the inner wall of at least one of the through holes, an electrically conductive film formed on the inner wall of at least one other through hole, and an electrically conductive material of a low melting point provided within the through holes. The low melting point material provided in the through holes whose inner walls are coated with an electrically insulating film is insulated from the electrically conductive plate and such through holes may serve to receive signal propagating pins.Type: GrantFiled: November 3, 1986Date of Patent: February 21, 1989Assignee: Hitachi, Ltd.Inventors: Masaaki Nishi, Moritoshi Yasunaga, Ryotaro Kamikawai

Patent number: 4734045Abstract: A high density connector for connecting multiple circuits between printed circuit boards or the like is formed of inter-engaging mating, first and second connector halves formed of an electrical insulating material with said connector halves including opposed connection faces having uniform width and height undulations forming alternating flattened peaks and valleys of limited width with the peaks and valleys having an electrically conductive coating thereon to form longitudinally spaced transversely offset contacts at the peaks and valleys. The connection faces of the respective connector halves bear mirror image undulations. The center to center distance between longitudinally adjacent contacts is less than the peak to valley distance between those contacts to increase the electrical creapage path between longitudinally adjacent contacts of the mating first and second connector halves.Type: GrantFiled: March 27, 1987Date of Patent: March 29, 1988Assignee: Masterite Industries, Inc.Inventor: John L.
