Abstract:
An electrical connector includes a positioning member; an insulated main body enclosing the positioning member from above and a plurality of terminals. Each terminal has a contact section embedded within a tongue plate of the insulated main body and an inclined section embedded partially within the positioning member via an insert-molding process. When the inclined section is further bent relative to the contact section, the uniform spacing and alignment among the terminals is maintained precisely due to the insert-molding process of the terminals in the insulated main body and the positioning member.

It is intended to achieve the weight reduction, sliming, and downsizing of bushings, compatibility of types of bushings, and simplification of operating steps. A polymer bushing comprises a conductor draw-out bar (1) having a conductor insertion hole (1a) in the lower end, a hard insulation sleeve (2) installed around the outer periphery of the conductor draw-out bar (1), a polymer clad body (3) installed around the outer periphery of the insulation sleeve (2), and an electric field stress-control layer installed on the interface between the insulation sleeve (2) and the polymer clad body (3). The insulation sleeve (2) comprises a large-diameter insulation sleeve (2a) installed around the outer periphery of the lower region of the conductor draw-out bar (1), and a small-diameter insulation sleeve (2b) installed around the outer periphery of a portion of the conductor draw-out bar (1) excluding the front end. An embedment metal part (4) for electric field mitigation purposes is embedded in a portion of connection between the large-and small-diameter insulation sleeves (2a, 2b). Further, installed at the lower end of the large-diameter insulation sleeve (2a) is a cone-shaped receiving port (5) for receiving the stress cone (13) of a cable terminal (11), the receiving port (5) communicating with the conductor insertion hole (1a) in the conductor draw-out bar (1).

Abstract:
A transmit and receive loop antenna includes a first loop element coupled to an electrical circuit element for generating near fields and far fields and a shunt loop element surrounding the first loop element such that voltages are induced in the shunt loop element by the fields generated by the first loop element. The shunt loop element is constructed from a continuous loop of conductor to maximize current from the voltages induced in the shunt loop element. The current in the shunt loop element generates fields which largely cancel the fields generated by the first loop element in the far field. Thus, the first loop element and the shunt loop element establish a surveillance zone in an area proximate the loop elements. A second loop element, such as a figure-8 loop element may be placed proximate the first loop element and the shunt loop element for receiving electromagnetic energy radiated by a tag circuit which enters the surveillance zone. The tag circuit inside the surveillance zone may be powered by the emitted electromagnetic field of the first loop element and the shunt loop element.
Abstract:
A dual cavity pressure microphone comprising a microphone housing and an oscillating element mounted in or on said housing. The oscillating element including a membrane which is in principle only sensitive to a sound field on one side, the second side forming part of a closed cavity in the microphone housing, said cavity being connected to the ambient atmosphere through a narrow pressure equalizing channel. The microphone comprises an additional cavity representing an additional acoustic capacitance and an additional pressure equalizing channel located in series therewith and representing an additional acoustic resistance, the second capacitance and the second resistane being located in series with the capacitance and resistance, respectively, of the first cavity and the first channel in such a manner, that the pressure equalization of the microphone is also effected through the additional pressure equalizing channel and the additional cavity. According to the invention the additional pressure equalizing channel is dimensioned in such a manner that it substantially only provides a static pressure equalization.
Abstract:
An electrical connector having an internal switch that is opened and closed when the plug and receptacle of the connector assembly are mated and unmated. When a source of electrical power is applied to the internal switch, the electrical connector provides an electrical signal when the electrical contacts of the plug and receptacle are unmated.
Abstract:
A plug has a cover hinged to a base. Terminals are provided with cutting tools which are mounted on the base. Channels in a block support wires with their ends projecting from a face of the block. When the cover and base are brought together about the hinge the cutting tool moves in front of the fact stripping insulation from the ends of the wires and clamping them against the face.
Abstract:
A connector for electrically connecting an electronic device to another device includes an outer shell with a front surface that terminates at a front side of the connector, an inner core at least partially disposed within the outer shell and including a front surface that is recessed within the outer shell, and a plurality of electrical connecting elements at least partially disposed within the inner core and extending from the front surface of the inner core. The plurality of electrical connecting elements includes a first set of electrical connecting elements and a second set of at least one electrical connecting element, and the first set of electrical connecting elements includes five connecting elements that are arranged in a pentagon pattern. The connector facilitates the transmission of audio signals between devices and also additional analog or digital signals or the transmission of a power supply between the devices.
Abstract:
A four-wire ohmmeter connector includes a pair of elongated members spaced apart from each other by an interconnecting web. A pair of elongated contacts are mounted on forwardly projecting portions of each of the elongated members. An insulative housing surrounds the elongated members, contacts and web. The contacts mounted on one of the elongated members are connected through separate wires to a positive probe, and the contacts mounted on the other of the elongated members are connected through separate wires to a negative probe. The elongated members are inserted into respective terminal apertures of a four-wire ohmmeter. A pair of semi-cylindrical conductive sleeves are aligned with each of the apertures, and they make contact with and compress the respective contacts that are inserted into the aperture.
