摘要:
A monitoring device for monitoring the operation of a hand-held pliers-type crimping tool, including a pair of pivotally connected handles for displacing a pair of crimping dies between open and closed crimping positions, a support seat connected with one of the handles for supporting at least one plug terminal between the crimping dies, a transport tool for transporting a plug terminal to a seated position on the support seat, and a counter arrangement on the transport tool for producing a signal that is a function of the number of displacements of the handles from the open position toward the closed position. The transport tool includes a housing, an electronic circuit including a counter mounted in the housing, a transport pin extending from the housing for insertion within one end of a hollow plug terminal, and a signal transmitting pin parallel with the transport pin.

An electrical module includes a rectangular carrier frame adapted for vertical transverse mounting on a horizontal support rail, a housing for mounting an electrical component in an open-top chamber contained in the carrier frame, and a rectangular electrical connector mounted on and extending across the upper end of the carrier frame, thereby to enclose the component and afford electrical connection with upper terminals thereof. The connector is pivotally connected at one end with the carrier frame for displacement between open and closed positions, and a fastener device serves to lock the connector in the closed position to the carrier frame. Alternatively, the ends of the connector are removably fastened to the carrier frame. Lower terminals of the component are connected with lower contacts arranged at the bottom of the chamber for connection with corresponding lower contacts of adjacent modules mounted in stacked relation on the support rail.

A connector apparatus connects the flat electrical conductors of a photovoltaic panel with a plurality of insulated electrical output conductors, respectively. The terminal portions of the flat conductors are bent into electrical engagement with corresponding blade contacts mounted on the photovoltaic panel. A plurality of resilient first electrical contacts are clamped in electrical engagement with the flat conductor bent portions, respectively, and a plurality of second electrical contacts are connected with the output conductors, respectively. An electrical circuit including a plurality of diodes is connected between the first and second electrical contacts. In order to dissipate the heat generated by the diodes, the diodes are mounted on a heat conducting plate that transmits the heat toward the photovoltaic panel. A cover member formed of heat conducting material is adhesively secured to the panel to enclose the connector arrangement, thereby to also transfer the diode-generated heat to the panel.

An electrical connector includes a U-shaped metal clamping frame having vertical base and side walls defining a chamber, a stationary electrical contact mounted in the chamber, and a clamping spring arrangement arranged at least partially within the chamber for biasing toward the electrical contact the bare end of an insulated conductor that is axially inserted downwardly into the chamber. The clamping spring comprises a conductive leaf spring having a clamping leg that is inclined, when in the conductor clamping position, at a first acute angle relative to the insertion axis of the conductor. In one embodiment, the clamping leg is supported by an attachment arrangement including an attachment leg arranged at second acute angle relative to the insertion axis. In another embodiment, the clamping leg is integrally connected with the clamping frame, and with the frame base wall defining the stationary electrical contact.

A plug connector and a method of coding of same is characterized by first and second coding elements that are pre-mountable as a unit on at least one of a pair of plug connector components. The other plug connector component is configured so that when the connector components are initially connected together in an axial direction, one of the coding elements is connected with one of the components and the other coding element is connected with the other component. When the components are separated axially, the respective coding elements are separated so that each are retained on the component with which it was originally connected.

A connector arrangement includes a flat conductor component having a flat engagement portion, a conductive bus bar component having a flat engagement portion, and a conductive contact screw connecting the conductor and bus bar flat engagement portions in contiguous surface-to-surface electrical engagement. The contact screw has a pointed tip and is axially displaceable from a retracted position normal to and spaced from the flat conductor and bus bar engagement portions toward a connected position in which a pointed end of the screw penetrates or extends through openings in the bus bar and flat conductor engagement portions, and into a bore contained in a housing support surface. The housing support surface supports the flat engagement portions in either a horizontal orientation or a slightly inclined orientation relative to the horizontal upper surface of electrical panel component to which the flat conductor is connected and upon which the housing is mounted.

Indicating apparatus for indicating the operating state of a component of an electrical load protection system, including a housing containing a longitudinal chamber, an indicating member mounted for longitudinal displacement in the chamber, a resilient device normally biasing the indicating member toward a first end of the housing, a catch arrangement for retaining the indicating member in a retracted position adjacent the housing second end; and a release device responsive to a trouble voltage pulse for operating the catch arrangement to a released condition, thereby to release the indicating member for displacement toward an indicating position adjacent the housing first end. At least the first end of the housing is transparent, thereby to provide a visual indication when the indicating member is in the indicating position. Switch contacts are operable between open and closed conditions when the indicating member is displaced between the indicating and retracted positions.
摘要:
An insulation stripping tool for flat cables includes a clamping device adapted to be clamped to a flat cable and to provide a linear guide edge for guiding a knife holder to accurately sever the outer insulation sheath of the cable in a transverse direction. Upon removal of the clamping device from the cable, the knife holder is inserted into a chamber contained in the clamping device with the knife edge protruding from the chamber, whereupon a curved side of the flat cable is inserted within first guide grooves contained in the clamping device, and the clamping device is displaced circumferentially of the cable to sever the curved cable side transversely of the cable. The curved cable side is then inserted into a second pair of grooves contained in the clamping device, and the knife holder is displaced longitudinally to sever the insulation sheath longitudinally of the cable.
