Abstract: An electrical connector includes an outer shell (400) which is profiled to receive a pin housing (450) therein. The pin housing (450) has mounted therein a plurality of pins (622). The interior of the housing shell (400) is sealed by placing a grommet (624) over the end of a wire (626) and placing the terminal (622), the grommet (624) and wire (626) into the rear of the connector shell (400). To prevent the ingress of water into the shell (400), the grommet (624) includes at its exterior end, an elongate collar (624b) which, if the wire is pulled, will compress. This prevents the exterior ribs from pulling away from the aperture allowing the ingress of water.

Abstract: A digital transversal filter includes first and second shift registers. A first digital data signal is applied as an input to the first shift register and a second digital data signal, which is a phase shifted version of the first digital data signal, is applied to the second shift register. First and second clock signals are used to clock the shift registers, and these clock signals correspond in frequency but differ in phase with respect to one another. The outputs of the stages of the first and second delay lines are weighted by respective resistors which are connected to a summing node. The digital data signal has a data clocking rate, the first and second clock signals have a delay line clocking rate, and the data clocking rate is slower than the delay line clocking rate.

Abstract: An electrical connector for connecting a first printed circuit board to a second printed circuit board has terminal contacts which provide a reliable electrical connection. The contact terminals are positioned adjacent to a board receiving recess, and are configured to make an electrical connection with the second printed circuit board when the second printed circuit board is rotated to a second position. Overstress projections provided on the contact terminals cooperate with shoulders of the electrical connector to prevent contact terminals from being deformed as the second printed circuit board is moved relative to the contact terminals. Contact projections are positioned on the contact terminals proximate a resilient contact arm. The contact projections electrically engage the resilient contact arm when the second printed circuit board is in the second position.

Abstract: An alignment and blind mate assist shroud (22) for positioning on a first end (34) of a connector housing (24) has a body section securable to the first end of the connector housing (24). The shroud has a key (75) receivable in a keyway (35) proximate the first end of the connector housing and a keying protrusion (150) adapted to extend beyond the mounting face (48,50) of the connector housing (24) to key the connector assembly (62) to a particular one of several possible assembly receiving locations on the circuit board (154) on which the assembly (62) is mounted. The polarization protrusion (150) cooperates with an aperture (152) in the circuit board (154) on which the connector assembly (62) is adapted to be mounted to assure that the appropriate connector assembly (62) is mounted at the corresponding location on the circuit board. An alignment and blind mate assist shroud (23) without a key or keying protrusion may be secured to the second end (34) of the connector housing (24).
