  • Patent number: 5207595
    Abstract: A terminal cover removably mountable on a watthour meter socket adapter includes an arm having an outwardly extending flange which is disposed in proximity with a sealing ring when the sealing ring is disposed about the mating mounting flange of a watthour meter and the rim of the socket adapter to lockingly mount the terminal cover on the socket adapter via the lock device carried by the sealing ring. In one embodiment, the flange on the arm has a predetermined length to engage a notch in the sealing ring to prevent rotation of the sealing ring. In another embodiment, the length of the flange on the arm is selected such that the flange lies between the sealing ring and the socket adapter housing to lockingly retain the terminal cover on the socket adapter housing when the sealing ring is locked about the mounting flange of the watthour meter and the rim of the socket adapter.

  • Patent number: 4977482
    Abstract: A watthour meter socket adapter includes a housing with electrical contacts which receive the terminals of a watthour meter and terminals which are insertable into the contacts of an electrical watthour meter socket. First and second seal connectors sealingly connect the adapter housing to the socket and a watthour meter to the adapter housing to control access to the socket, adapter and watthour meter. The interface connection includes an electrical connector mounted in an enclosure and connected to the contacts in the adapter housing to provide electrical power to an external interface. A third seal is connected and attached to the enclosure to control access to the electrical connections housed therein. In one embodiment, the enclosure is separate from and mounted on the adapter housing. In another embodiment, the enclosure is in the form of a sleeve mounted internally within the adapter housing with an open end allowing connection to an external electrical device.

  • Patent number: 4934747
    Abstract: A sealing ring for an electric meter socket has first and second spaced ends. A tongue with a plurality of linearly spaced apertures extends linearly outward from the first end of the sealing ring. A housing is mounted on the second end of the sealing ring and includes a passage for receiving the tongue therethrough. A threaded fastener is mounted in the housing and engages successive apertures in the tongue to advance and retract the tongue through the housing to connect and disconnect the sealing ring about the electric meter socket. At least one and preferably two seal tabs extend outward from the second end of the band and engage the apertures in the tongue. A seal member is emplaceable through the seal tabs to indicate a sealed mounting on the sealing ring on the electric meter socket.

  • Patent number: 4622753
    Abstract: A repair kit for an electric meter socket, which includes a set of jaw contacts mounted on a support plate, with means for mounting said plate in a desired spaced relation to the back of the meter box so that the blade contacts of the meter will be inserted into the jaw contacts for a suitable depth when assembled, and a template for temporarily mounting into the meter aperture in the meter box cover, said template having a series of guide holes for receiving a punch for marking the position for plate mounting holes in the back of the meter box, and means for orienting said template so that said holes will be in a position such as to allow the meter to be in a desired orientation after assembly.
