Abstract: A terminal assembly module is provided that simplifies the transfer of I/O wiring from a pre-existing industrial controller to a replacement industrial controller. The terminal assembly module replaces an I/O module in the pre-existing industrial controller chassis. The I/O module terminal block, with I/O wiring maintained intact, is removed from the discarded I/O module and installed on the terminal assembly module. A multi-conductor cable is then plugged into a cable connector on the front of the terminal assembly module, which electrically connects the I/O module terminals to the conductors of the cable. The cable conductors can then be connected to the I/O modules of the new industrial controller. Thus, the terminal assembly module eliminates the need to disconnect the existing I/O wiring from the I/O module terminal blocks of the pre-existing industrial controller.

Abstract: A modular bus interconnect system suitable for ganging together modules where the electronic signals are bussed to respective contacts on each module. The modules may be releasably or permanently attached to each other. The modules each have a slot for receiving and electrical contacts for making electrical connections to the contact fingers of an edge board connector. Each of the module's electrical contacts has a cantilever portion for making electrical connections to the connector fingers, and, in addition to the cantilever portion, each module has at least two exposed electrical contact portions that are formed on the outside of the housing. When the modules are ganged together these exposed portions are arranged to make electrical connections with each other thereby distributing the signals among all ganged modules.

Abstract: An electrical connector for joining individual, electrically conductive wires, to a printed circuit board. The wires may be individual solid or stranded types. A contact, provided within the connector housing, is arranged with a first end forming an area for attaching the wire and with a second end arranged usually with female contacts for connecting to a header on the printed circuit board. The wires are stripped of any insulation and mechanically attached to a contact in the connector. The wire is placed between a pressure plate and an area of the contact. A screw is rotated forcing the pressure plate and the contact area together physically squeezing the wire so that the wire is securely attached to the contact area to provide a good electrical contact. The second end of the contacts forms a female cantilevered contact arranged to mate with a header of a row of male pins soldered to the printed circuit board.

Abstract: An electrical connection system comprises a first component carrying a pair of male connector elements releasably mated with a pair of female connector elements carried by a second connector component. A shorting clip is associated with the first component for providing an electrical short between the male connector elements. The shorting clip is moved to a non-shorting position when the first component is mated with the second component. An interlock is associated with the system and includes a lock element which is inserted into the connection to prevent separation of the first and second components while the lock element is in position.

Abstract: An electrical connection system comprises a first component carrying a pair of male connector elements releasably mated with a pair of female connector elements carried by a second connector component. A shorting clip is associated with the first component for providing an electrical short between the male connector elements. A safety latch is selectively receivable in a latch position for moving the shorting clip to a non-shorting position when the first component is mated with the second component and a lock element is arranged to be actuated by the safety latch to prevent separation of the first and second components while the safety latch is in the latch position.
