The motion control system further comprises a scalable motion controller connected to the motion unit wherein the scalable motion controller receives signals from the encoder and outputs signals to the amplifier. The scalable motion controller comprises a plurality of dip sockets arranged for inserting and removing one or more motion control processors and a connector interface comprising a plurality of male and female connectors arranged for stacking a plurality of motion controllers.

Abstract: The invention provides a method of forming an electrical contact device and a pre-assembly for producing the electrical contact device. The electrical contact device is formed by providing a conducting frame and an insulating frame which is added to predetermined portions of the conducting frame to form the pre-assembly. A plurality of fine pitch electrical leads are disposed in parallel spaced apart relation and connected to each other by connecting strips. An insulating material is applied to the conducting frame to form the insulating frame. The insulating frame encapsulates portions of the electrical leads which extend from opposite sides of the center of the insulating frame retaining, therefore, the electrical leads in position and electrically isolated from one another. Portions of the conducting frame are then removed from the pre-assembly to obtain the electrical device.

Abstract: A computer chassis includes a metal chassis base portion and a metal chassis top portion. A pivotal connection is provided between the top portion and the base portion for movement of the top portion between an open position and a closed position with the base portion. A tongue and groove edge connection extends between the top portion and the base portion. An adhesive free gasket is mounted in the groove for sealing engagement with the tongue.

Abstract: An electrical connector is shown for stacking a plurality of printed circuit boards one above the other, where some of the terminals extending from the lower portion of the housing include both printed circuit board contacts as well as mating contacts for the next adjacent connector. The connector housing includes integral stand-offs for maintaining the parallel nature of the stacked boards, as well as a precise spacing between the boards. The connector housings can include stand-off members which are frangible and can be used to maintain the parallel nature of the boards when other connector housings of a similar height are not used.

Abstract: An extender or cover is provided for fitting over partition walls between adjacent sets of terminal points or connectors on an electrical terminal block. When installed, the extender serves as a mechanical barrier against inadvertent connection of terminals of different electrical polarity or potential. The extender also serves as a visible cautionary indicator, alerting the service crew to be aware of the risk of misconnection.

Abstract: An electrical connector assembly is disclosed to include at least a pair of connector housings having complementary interengaging locking devices for interlocking the connector housings with the centerlines at a first spacing. Frangible webs interconnect the connector housings with their centerlines at a second spacing. Therefore, the connector housings can be used in conjunction with each other at the second spacing, and the frangible webs can be broken to allow interlocking of the connector housings for use in conjunction with each other at the first spacing.

Abstract: Electrical connectors each having one row of electrical terminals, are joined together in end to end relationship by slugs formed integrally with end walls of the connectors. Lead receiving portions of the terminals of both of the connectors are loaded with electrical leads, which extend therefrom in the same direction. The slugs are then removed so as to separate the connectors. Dovetail cross section ribs on a side wall of one connector are then slid into complementary grooves in a side wall of the other connector so as to couple the connectors together in back to back relationship, with the leads projecting from opposite sides of the composite two row connector so provided. The invention enables the leads to be loaded into the connectors by means of a lead loading apparatus which is capable of loading electrical connectors only from one side thereof.

Abstract: A modular electrical connector including an elongate housing defining at least two laterally spaced, generally parallel rows of equally spaced contact supporting cavities. The cavities in each row are in longitudinal positions offset relative to the longitudinal positions of corresponding ones of the cavities in the opposite row. Equal numbers of cavities are provided in each row, and the break-away walls are located for separating the cavities into modules of varying numbers of sets of cavities with one cavity in each set being from each row. The break-away walls are located between adjacent cavities in each row, and rigid supporting walls extend laterally between each opposing cavity of each set. The cavities have common mating ends and conductor terminating ends, with the conductor terminating ends of all the cavities having access slots on one side of the connector for receiving conductors therethrough for termination to appropriate insulation displacement contacts supported in the cavities.

Abstract: An electrical connector including an insulator and a number of contacts for mounting on a substrate such as a printed circuit board. As disclosed, the electrical connector includes an elongated insulator block carrying contacts in the form of pins, an end of each of which is received in a printed circuit board aperture to be soldered to the printed circuit board. The elongated insulator block further includes a series of holes, each intermediate an adjacent pair of contacts of the connector, precisely located relative to the contact locations, to facilitate positioning the connector for insertion of the pins into a printed circuit board. The insulator block is notched adjacent each of the holes to facilitate breaking the connector to a desired length, and hence containing a desired number of contacts. The insulator block further has generally semi-cylindrical indentations at each of its ends.
