Abstract:
A method and apparatus for carrying a battery of a portable communication device. The battery carrier includes a body, a carrier sealing surface, and a wiper. The carrier sealing surface engages a battery seal while the battery is positioned in the battery carrier. The wiper is positioned on a support surface of a battery receptacle in the body. The wiper is aligned with battery contacts of the battery. The wiper wipes the electrical contacts when the battery is inserted into the battery receptacle.
Abstract:
A method and apparatus for determining the current condition of power contacts and providing an indication to a preventive maintenance system and/or a user of required power contact replacement. The method includes auxiliary contacts providing a low power binary signal to a processor in response to movements of a contact carrier supporting the movable auxiliary contacts and movable power contacts. The low power binary signals, in combination with physical features of the contact carrier and a signal indicating the state of the power contact, provide information to the processor for determining the current condition of the power contacts, and if the current condition exceeds a predetermined limit, notifying the preventive maintenance system and/or the user.
Abstract:
A receptacle connector is provided for a wearable article. The receptacle connector includes a housing having a receptacle configured to receive a complementary plug connector therein. The housing is configured to be mounted to the wearable article. A printed circuit board is held by the housing. The printed circuit board includes mating contacts for mating with the plug connector. The printed circuit board includes mounting contacts that are configured to terminate conductors of a flat cable of the wearable article or an e-textile of the wearable article.
Abstract:
An electrical transmission line repair device including a first conductor clamp, a second conductor clamp and at least one tie rail extending between the first and second conductor clamps in a spaced apart orientation. The first conductor clamp including a lower assembly and an upper assembly. The lower assembly and the upper assembly are slidably engageable with each other so as to define a conductor cavity extending therealong. Clamping fasteners are configured to extend through openings in the upper assembly so as to be threadable toward and away from the conductor contact region of the lower assembly within the conductor cavity.
Abstract:
Methods and systems for monitoring a brush holder assembly and/or detecting wear of a brush in a brush holder assembly are disclosed. One method includes sending data from a plurality of remote monitoring locations to a central control unit, where the data may be evaluated in order to monitor states of brushes at a plurality of remote electrical facilities. For example, multiple images of a marker tracking longitudinal movement of the brush may be acquired. A comparison of the images, for example, a comparative imaging technique, such as pixel-by-pixel comparison, may then be performed in order to evaluate a condition of the brush, such as the wear rate, wear state, or life expectancy of the brush.
Abstract:
A receptacle cleaning assembly for use with electrical connectors includes a receptacle washing fixture having a manifold body with a solution inlet and outlet. A plurality of nozzles, in communication with the solution inlet, are coupled with the manifold body and are arranged in a pattern corresponding to female connector receptacles. An interface seal is coupled with the manifold body. The plurality of nozzles extend through the interface seal, and the interface seal is configured to seal along a face of the connector. At least one solution return passage extends through the interface seal from an exterior of the plurality of nozzles to the solution outlet. An alignment skirt extends from the manifold body, and couples and aligns the connector receptacles with the plurality of nozzles. In another example, the receptacle cleaning assembly includes a receptacle brush fixture including a plurality of reciprocating brushes for use in the female connector receptacles.
Abstract:
A connector (C) in which pin-like terminal fittings (6) project from the back surface of a housing (1) is held in a setting tool (9) including an opening (13). The connector (C) then is conveyed to an operation position together with the setting tool (9). At the operation position, a suction device (16) is located to communicate with the opening (13) from below and a nozzle (21) is located above the opening (13). Cooled dry ice fine particles are blown toward the housing (1) and the terminal fittings (6) from the nozzle (21). Foreign matters with reduced adhering forces by being cooled come off from the adhering surfaces and are sucked and collected by the suction device (16).
Abstract:
A connector includes, in one embodiment, a body assembly configured to be secured to a prepared end of a coaxial cable. The connector has a coupler assembly connected to the body assembly for connecting the body assembly to an interface port. The connector also has a flexible interlock to facilitate repeated assembly and disassembly of the connector.
Abstract:
An apparatus for locking out an elevated bus plug includes an elongated member, a lockout device at a distal end portion of the elongated member and an actuator at a proximal end portion of the elongated member. The lockout device includes a housing, a channel in the housing that is sized and configured to receive a handle of the bus plug and a handle engagement mechanism connected to the housing. The handle engagement mechanism is configured to engage a handle of the bus plug that has been received in the channel responsive to actuation of the actuator.
Abstract:
In one possible implementation, a method is provided for determining contactor health including measuring a differential voltage between a first utility line voltage and a second utility line voltage on a primary side of a contactor and on a secondary side of the contactor. The measuring is performed with both an unloaded current and with a load current. The unloaded and loaded measurements are performed at the primary side and the secondary side, and are made with the contactor closed. It includes determining a difference between a secondary unloaded voltage and a secondary loaded voltage and subtracting a difference between a primary unloaded voltage and a primary loaded voltage to provide a contactor voltage drop. The contactor resistance is determined by dividing the contactor voltage drop by the loaded current.
