A hybrid electronic/mechanical scanning array antenna including an outer housing and a cold plate rotatable therein. A waveguide aperture including an array of antenna elements is mounted to a top surface of the cold plate and a multi-layer circuit board is mounted to a bottom surface of the cold plate. A plurality of amplifier modules are mounted to the cold plate, where the circuit board includes a plurality of openings that allow the amplifier modules to be directly mounted to the cold plate, and the cold plate includes a plurality of RF signal channels that allow RF signals from the amplifier modules to travel through the cold plate. The amplifier modules are controlled to provide phase-weighting for electronic signal scanning in an elevation direction and rotation of the cold plate allows signal scanning in an azimuth direction.

A mating pair of low insert ion force contacts comprises a female contact device and a male contact matingly engaged with each other. The female contact device comprises a first arm and a second arm insert molded in a dielectric housing. The first arm and the second arm respectively have a first spring contact portion and a second spring contact portion extending out from a front face of the dielectric housing. The first arm has a tail portion extending out from a rear face of the dielectric housing, and the first arm and the second arm are split with each other. A male contact has a slant head connected to two oppositely protruded snaps which are connected to a slant section coplanar with the slant head. The male contact may be engaged with the female contact device by moving the slant head of the male contact into a space between the first spring contact portion and the second spring contact portion and driving the oppositely protruded snaps to respectively wipe against the first spring contact portion and the second spring contact portion.

An electrical connector assembly comprises an elongate holder defining a recessed planar field. A pair of towers extends upward from transverse ends thereof and is located adjacent to the recessed planar field. Side ribs extend inward from the towers defining retaining grooves between the side ribs and the holder. An elongate housing is assembled to the holder, and includes side tabs fixedly retained in the retaining grooves. The elongate housing defines a cutout such that the recessed planar field is accessible through the cutout. A plurality of terminal is integrally formed with the housing and each terminal includes a body portion retained in the housing. A contact portion extends above the housing, and a contact tail extends into the cutout. A flexible flat cable is inserted into a gap defined between the recessed planar field and the housing, and with conductors thereon aligned with the solder tails.

A stacked connector assembly includes a docking connector and an ultra SCSI connector arranged on the docking connector. A bracket has two spaced legs standing on a circuit board and a top panel mounted to the legs for supporting the ultra SCSI connector thereunder. Resilient barbs are formed on the docking connector and extend upwardly therefrom for snappingly fitting in notches defined in the ultra SCSI connector thereby attaching the docking connector to the ultra SCSI connector. Board locks are mounted to both the ultra SCSI connector and the docking connector and engage with corresponding holes defined in a circuit board for securing the stacked connector assembly to the circuit board.

A centronic connector assembly comprises a lower cover and an upper cover assembled to the lower cover defining a receiving space therebetween. A lower EMI shield and an upper EMI shield are assembled in the receiving space. One of the EMI shields includes a mount on a wall thereof. A centronic connector including a housing having front and rear faces is assembled to the covers. A printed circuit board is assembled to the rear face of the connector at a first end and a second end opposite the first end is securely supported by the mount.

An electrical cable connector assembly includes a connector and a cable. The connector includes a housing enclosing an insulator with contacts fixed thereto. The cable has a number of wires with leads electrically connected to the contacts. A plastic strain relief is fixedly attached to the cable by insert molding, and has two keys engagably received within two grooves defined by the housing. A metal strain relief is formed by stamping a metal sheet to have a hollow body portion and two fitting wings extending from opposite sides thereof. The body portion is crimped to be fixedly connected to the cable near the plastic strain relief. The wings are fittingly received between a stop wall and either a connecting post or sleeve formed on a lower housing member of the housing. Through cooperation between the metal and plastic strain reliefs, a large withdrawal force acting on the cable relative to the connector can be effectively transmitted to the housing to prevent the withdrawal force from affecting the leads of the cable.

A modular jack includes an insulative housing, a cavity defined in the housing, and a plurality of contacts extending into the cavity for connecting with wires extending from a lower portion of a rear face of the housing. A retaining spacer is integrally formed on a middle portion of the rear face of the housing. The spacer defines a plurality of grooves for snugly receiving a corresponding plurality of wires therein, respectively. The provision of the retaining spacer promotes conservation of space on the PCB on a portion thereof adjacent to the rear face of the housing of the modular jack.

An electrical connector comprises a plug, a printed circuit board, and a contact unit mounted on the printed circuit board and comprising a plurality of contacts with an insulative housing formed therearound. The PCB together with the contact unit is slidably received in a slot defined in the plug wherein a snap lock device securely retains the PCB in the plug. A plurality of contact receiving passageways are defined in the plug each having a lip protruding therein from a rear end of the plug. Each lip engages with a tail end of the corresponding contact thereby preventing inadvertent deformation of the contact during assembly with a mating receptacle connector.

A connector assembly includes an insulative unitary housing defining an upper section and a lower section wherein each section defines a plurality of passageways for allowing a corresponding number of contacts extending therethrough for receipt within the mating port thereof. A pair of side walls are provided on two lengthwise opposite ends of the housing wherein the upper portion of each side wall is shorter than the lower portion thereof. The upper portion defines an upper boardlock receiving region and the lower portion defines a lower boardlock receiving region whereby both of the upper boardlock and the lower boardlock have mounting legs extending downward out of the bottom surface of the housing for reaching the PC board on which the connector assembly is mounted and wherein the leg of the lower boardlock is aligned with and in front of that of the upper boardlock in a front-to-end direction. A spacer is positioned in a space defined between such pair of side walls and includes a plurality of apertures for vertical alignment of the contact tails of both the upper section and the lower section.

Connector assembly

An electrical connector assembly includes a receptacle connector disposed in an electrical device and a plug connector connected to an external power supply. A metal shield is formed by stamping a metal sheet and has latching portions outwardly extending from side walls thereof. Engaging arms rearwardly extend from the shield for securely engaging with corresponding apertures defined in a housing of the receptacle connector. Each latching portion defines a square opening therein for receiving a resilient latch of the plug connector. Each latch has a first portion outwardly extending from a mating face of the plug connector, a second portion connected to the first portion and extending toward the mating face, and a third portion connected to the second portion and extending toward the first portion.
