Abstract:
A probe for an in-circuit emulator for use in program verification and debugging during development of an equipment using a microcomputer is disclosed. The probe is formed by a flexible printed circuit board on which a plurality of conductive lines and a plurality of solder-connecting elements are provided. The conductive lines and the solder-connecting elements are electrically connected through a plurality of through-holes provided in the flexible printed circuit board. The solder-connecting elements of the probe are solder-connected to conductive lines of a target board to be emulated. The in-circuit emulator does not require a dummy chip, which makes the probe simple in its structure and economical in the fabrication thereof.
Abstract:
A modem located on a PC card. An I/O socket is mounted on one end of the PC card and sideswipe contacts are positioned long e one or more sides. The I/O socket has a plurality of positions including one or more positions which are electrically connected to the modem. A relay is located in the PC card, and has one side connected in common to the modem and the positions on the I/O socket. The other side of the relay is connected to the sideswipe connectors. The control input to the relay is connected to a position of the I/O socket separate from the modem positions. A voltage source is connected to a position in the socket separate from the modem positions and the control signal position. An I/O plug is designed to have one side connected to the telephone network and the other side connected to the I/O socket such that all pins in the plug mate with the corresponding positions in the I/O socket. The I/O plug contains a lead interconnecting and creating a short circuit between the pin in the I/O plug which mates with the position in the I/O socket connected to the control input of the relay and the pin in the I/O plug which mates with the position in the socket connected to the voltage source. This causes the voltage source to appear on the input of the relay when the I/O plug is inserted into the I/O socket.
Abstract:
An electrical connector component assembly terminates discrete conductors of a multiconductor data cable. The component assembly includes an insulative component housing having a mating end for engagement with a mating electrical connection device and a cable receiving end for terminating the multiconductor cable. A plurality of electrical contacts are supported by the component housing. Each of the contacts has a conductor terminating end and a mating connection end. The contacts are supported in the component housing in a pair of horizontally extending, vertically spaced rows with each contact of one row being aligned with a respective contact of the other row. The contacts of one row are directly electrically shunted to the aligned contacts of the other row.
Abstract:
A connecting block is used to connect a single 10 base T cable to two separate devices such as computer terminals or personal computers. The connecting block allows a single cable arranged to transfer signals for a single computer terminal or personal computer to two such devices by separating the signals in the cable into two sets of the four signals required to carry signals to such devices. Advantageously, the building wiring for 10 base T networks can have its capacity essentially doubled without performing any rewiring or adding electronic equipment.

Abstract:
This invention is directed to an electrical connector for sequentially connecting plural contacts provided along the respective mating surfaces of a pair of planar electronic devices, where the devices are joined to or mounted within a pair of pivotally arranged housing members. The connector comprises a first housing mounted to one of the planar devices, such as a mother board, where first housing includes an open end and a closed end, and a second housing mounting the other planar electronic device, such as a daughter board, second housing includes an open end and a closed end, and that the respective closed ends include cooperative means for hingely engaging each other. By this arrangement, as the planar electronic devices are pivotally moved about the cooperative means from a nonparallel position to a parallel position of electrical engagement, the respective plural contacts between the planar electronic devices enter into engagement in a sequentially predetermined order.
Abstract:
A closed type built-up receptacle assembly comprised of at least one receptacle retained inside a hole on a wall by a mounting plate, and a face panel covered on said mounting plate, wherein each receptacle is comprised of a receptacle body supported on a compression spring and held in a casing by a holder, a covering covered on the casing over the receptacle body, and two movable plates controlled by torsional springs to close the opening on the covering and the plug hole on the receptacle body.
Abstract:
A shifting connection device compises a connector and a plurality of conductive spring strips. The connector has a base part with a plurality of sockets and has a supporting board extending out of the base part along the central portion. A plurality of spaced elongated recess positions are provided on the supporting board to be attached by the plurality of conductive spring strips. Each socket in the connector has a wall surface inclining inward near the top of the base part to make the respective outer side of the base part produce an elastic force to press the plurality of conductive spring strips against the plurality of recess sections.
Abstract:
An electrical connector (10) for a detachable power cord (18) that can be selectively locked in place when engaged in a standard appliance power socket (80) of an electrically powered applicance or device that utilizes a detachable power cord, such as a personal computer or a desk-top laser printer, for instance. A securing means (64, 88, 106) is provided to prevent removal of the connector from the appliance power socket, which in turn prevents circumvention of any access-control means that may be operatively associated with the power cord. A controlled-access operating means (30) is provided whereby an authorized user can lock the connector into or unlock the connector from the appliance power socket.
Abstract:
A modular RF apparatus includes an RF portal and an RF expansion module configured to be coupled with the RF portal. The modular RF apparatus is configured to expand the number of outputs of the RF portal by adding the RF expansion module in a manner that minimizes an increase in the spatial footprint of the modular RF apparatus while allowing easy access to all ports of the modular RF apparatus. The RF portal and the RF expansion module are configured to interlock to create an integrated functional block. The modular RF apparatus are configured to permit upgrading of the RF portal by adding the RF expansion module without disrupting existing connections to the RF portal.
Abstract:
A connector includes a connector module and a housing. The connector module includes at least four cable assemblies with a same structure and a housing fastener. The housing includes a first mounting opening, and the housing fastener includes a second mounting opening. One end of each cable assembly of the connector module is inserted into the second mounting opening. The housing fastener of the connector module is inserted into the first mounting opening. The at least four cable assemblies with the same structure are disposed in the connector module. Each component of the cable assembly uses a mold, and different cable assemblies may share the mold.
