Patent number: 5558525Abstract: Automation equipment includes at least one removable interface module containing processor electronics on at least one printed circuit electrically connected to an interconnect printed circuit carried by a support via respective connectors. The printed circuit is accommodated in a casing of the module fixed to the support and electrically connected to a conductive part of the latter by a frame ground connection device which has connecting members fastened to the support and to the module, whereby mutual electrical contact is established between the module and the support. The connection members include a male member and a female member adapted to cooperate plug-and-socket fashion, and the interconnect printed circuit includes an opening through which at least one of the connecting members passes when the module is mounted on the support. This connecting member is insulated from the interconnect printed circuit where it passes through the opening.Type: GrantFiled: April 4, 1995Date of Patent: September 24, 1996Assignee: AEG Schneider AutomationInventor: Pascal Malgouires

Patent number: 5556301Abstract: A connector housing includes a terminal accommodating chamber communicated through a cutout portion with a space or central chamber in which a joint terminal is accommodated. A terminal is provided with a tongue member resiliently contacting with a short circuit terminal through the cutout portion. When the terminal is inserted into the terminal accommodating chamber, the tongue member contacts and electrically communicates with the short circuit terminal through the cutout portion. The lock piece for holding the terminal is provided on a peripheral wall of the terminal accommodating chamber 11 on a side opposite to the side on which the cutout portion is formed. Therefore, a gap is formed in the periphery of the lock piece. When a current of high intensity flows, the outside of the housing is covered with the cap so as to cover the gap, and the thickness is increased for enhancing the insulating property.Type: GrantFiled: November 22, 1994Date of Patent: September 17, 1996Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Masamitsu Chishima, Yutaka Noro
