Distinct Manipulating Means; E.g., Hot Stick Patents (Class 439/480)
  • Patent number: 10283882
    Abstract: A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a hot-stick. A clamping member cooperates with a frame having an arm, and is selectively biasable by a user to translate the clamping member relative to the frame to clamp a conductor between the clamping member and arm. The lock-out cooperates with the clamping member to prevent the translation of the clamping member unless in the presence of an insulating tool such as a hot-stick.

  • Patent number: 5427538
    Abstract: A device electrically interconnects a high voltage cable to a bushing of a deadfront electrical apparatus or switchgear. The device comprises a feed-through bushing and a separate U-member. The U-member can be installed onto, or removed from, the bushings without having to disconnect the ground. A driver mechanism applies a force to the U-member at a location substantially midway between two parallel legs of the U-member for installing or removing the U-member without cocking of the legs. The U-member carries female contacts which are engageable with male contacts of the bushings.

  • Patent number: 5405271
    Abstract: An assembly tool helps connect an electrical external half-connector to an internal half-connector at an aperture in a ballast case. The tool includes a fulcrum for stabilizing the tool against the case, and tongue for pushing the external half-connector into engagement while clearing the connector wires, to avoid damage. A handle of the tool is used to rotate the tool about the fulcrum. If the connector has a latch to deter pull-out, the tool also preactuates or depresses the latch to eliminate frictional resistance to inserting the latch--and so reduce the required engagement force. Latch depression is simultaneous with the point in the insertion process where the latch hook passes its mating engagement member. The tool dimensions provide a high mechanical advantage to help push the two connector halves together against friction. The tool converts the connector-engaging task from wrist action to a stress-free upper-body movement.

The connector is for location below a pole-mounted transformer and may be opened or closed from the ground with the use of a tool such as a hot stick. The connector includes two switches for releasable electrical connection of the secondary and service leads. Each switch has a rigid immovable member, a movable member and fastener. The movable member may be brought into contact with and fastened in electrical connection with the rigid member for a closed position of the switch. The fastener may be released and the movable member moved out of electrical contact with the rigid member for an open position of the switch. There are two embodiments disclosed. In the disclosed embodiments, the movable member of each switch includes a flexible cable and the connector includes a spacer between the cables to prevent electical connection therebetween when the switches are open.

  • Patent number: 4946394
    Abstract: A connection mechanism for connecting and disconnecting a cable connector to a bushing mounted on an electrical apparatus which is easier to use than cable connectors which require the threading of one electrical contact into another and which require more than one person to operate the connection mechanism. The connection mechanism assists in properly aligning the cable connector and the bushing and securely connects the cable connector to the bushing. Further, this connection mechanism eliminates the problem present in prior connection mechanisms of having to supply significant force in order to break the rubber-to-rubber interface bond which can occur when the connector has been connected to the bushing for a substantial period of time.
