Abstract: An assembly for forming two bridge connections between two contact members has two bridge conductors and two U-shaped spring clips which hold contact arms at the ends of the bridge conductors against contact members to form two separate electrical connections between the contact members. An insulating housing surrounds the conductors and clips.

Abstract: An electrical terminal or spring terminal for forming an electrical connection between a wire conductor and a current bar includes a spring and a spring retainer, the spring retainer not integral with the spring and not integral with the current bar. Engageable abutment surfaces on the spring retainer and the current bar cooperate to transfer spring force to the current bar.

Abstract: A base element and a surge protection system incorporating the base element are provided. The base element includes a housing having a front portion and a rear portion. Apertures in the rear portion provide access to contacts secured within the housing, and a receiving portion extending from the front portion includes at least one receiving section for receiving a surge protection cartridge. Plug receptacles in the receiving portion are in electrical communication with the contacts to incorporate the surge protection device in a circuit when the surge protection cartridge is inserted. The base element is configured to mount orthogonally to a case such that conductors secured to the contacts extend through the apertures and into an enclosure defined by the case in a substantially linear direction. The system includes a case configured to be attached to a rack mount system and a plurality of base elements secured to the case.

Abstract: A shelf lighting connector assembly provides an electrical connection between a power strip on a wall and a light mounted on the underside of a shelf mounted on the wall.

Abstract: A modular electric power distribution system distributes electric power between a power source and control modules for power consumers or other electronic components.

Abstract: A modular electric power distribution system transmits power between a power source and control modules for power consumers. The system includes a power distribution unit mounted on each module and bridge assemblies which connect adjacent distribution units.

Abstract: A network diagnostic module coupleable to a distributed process control network that controls an industrial process via field devices coupled to the network includes a power block coupleable to the network and configured to power the network diagnostic module with energy received from the network, a communications block coupleable to the network and configured to bi-directionally communicate over the network, and a diagnostics block coupleable to the network and configured to make diagnostic measurements of network and protocol parameters of the network. The network diagnostic module is not itself a field device that detects or controls any process variable of the industrial process, enabling the network diagnostic module to be placed essentially anywhere along the network to permanently monitor the network.

Abstract: A terminal block for mounting on a DIN rail includes a plurality of stacked modules with each module having a contact body and an extender body mounted on the contact body. A circuit board or electronic component is mounted on the contact body and the extender body. Different size extender bodies may be mounted on a common contact body to accommodate mounting different size circuit boards or components on the block.

Abstract: A method for removing an electronic module from a base where the module includes a latch extractor assembly and a stiff shift member with latch arms outside the module body and follower arms inside the module body. An extractor engages the follower arms to move the shift member laterally and move the latch arms out of engagement with the base to free the module for removal from the base.

Abstract: A torque-limited fastener turnable in fastening and loosening directions for one-time use includes a fastener head with a base, a set of lugs extending from the base, and an optional set of ramps extending from the base. The lugs include abutment surfaces facing a fastening tool slot recess that receives a fastening tool. When the fastening tool is turned in the fastening direction it bears against the lug surfaces. The lugs shear off or plastically deform into recesses when the fastening tool applies a limiting fastening torque. The ramps have abutment surfaces facing a loosening tool slot recess that receives a loosening tool. The ramps cam the fastening tool over the ramp abutment surfaces if the fastening tool is in the fastening tool recess and is turned in the fastening direction after the lugs have sheared off or have plastically deformed in response to application of the limiting torque.

Abstract: A wireless field device or an adapter for converting a wired field device to a wireless field device includes a housing, a first connector on the housing, and a removable antenna module that includes an antenna, a second connector coupleable and uncoupleable with the first connector, and a radome that houses the antenna and fits on the second connector. The radome is made of a static dissipative material that dissipates static buildup without sparking when coupling or uncoupling the connectors, enabling the antenna to be removed or replaced while the field wireless field device is located in a hazardous (classified) location.

Abstract: A terminal block is disclosed that integrates a surge protection base, a disconnect and connection points to provide a Kelvin connection in which a surge protection element is in electrical communication with the ground and the connection points for incoming and outgoing wires. The terminal block includes a terminal body having a terminal body housing, a plurality of conductive elements arranged within the terminal body to create a continuous electrical path therethrough and a disconnect switch integral the terminal body, the switch arranged to open the continuous electrical path and expose a terminal. The terminal body is configured to receive a surge protection element and the surge protection element, when received in the terminal body, forms a portion of the continuous electrical path.

Abstract: A connector socket with a body, a circuit board in the body and a header on the board. The contacts of terminals on the header are positioned in desired locations in openings in the body.

Abstract: A method for mounting a latch to a base, the base having an interior cavity for an electronic component, the latch configured to receive a support member for mounting the base to the support member, includes the steps of attaching a release member to the base and holding the release member in a stationary position, placing a latch against the base and forming a connection between the release member and the latch, and moving the release member and latch to a second position where the latch and release member are freely movable between latched and unlatched positions.

Abstract: An electrical connector for a power cable having a lead assembly which forms electrical connections between wires in the cable and contacts to one side of the cable.
