Assignee:

Ekstrom Industries, Inc. - Farmington Hills MI

International Classification:

H01R 33/945

US Classification:

439517, 439146, 439508

Abstract:

A watthour meter socket adapter has housing formed of snap together rear and front housings. The front housing surrounds but allows access to jaw contacts and terminals mounted in the rear housing by a watthour meter and electric power conductors. An aperture in the front housing engages a socket adapter mounting fastener extendible through the aperture to attach the socket adapter to a mounting surface. The fastener and aperture resist separation of the front housing from the rear housing when a watthour meter is removed from the socket adapter. A clip extends from the front housing through an aperture in a terminal cover attachable to the front housing and receives a seal lock member. Another clip on the front housing extends through the terminal cover and is engaged by an expandable ring lock clip. A meter surge guard is removably mountable to the rear housing and exteriorly of the front housing.

B23P 11/00

US Classification:

70 52, 29428

Abstract:

A lock apparatus includes a lock body which is slidably mountable over the legs of the shackle. At least one push nut is mounted within a recess carried in the lock body to allow easy insertion of the legs of the shackle through the bores in the lock sections and the at least one push nut, but exerts a substantial force resisting separation of the lock body from the shackle in an opposite direction. The lock body is formed of a unitary one-piece body, or a pair of identical lock sections which are reoriented with respect to each other and inter-engaged to form bores at one edge which receive the legs of the shackle. A method of installing the lock apparatus includes mounting at least one push nut in a lock body and then inserting the legs of the shackle through bores in the lock body and the at least one push nut.

International Classification:

E05C 1918

US Classification:

29225667

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.

International Classification:

H02B 100

US Classification:

361366

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.

International Classification:

H02B 100

US Classification:

439517

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. In another embodiment, the terminal cover includes an outwardly extending filler portion which has an arcuate wall formed at an outer end. An annular flange and peripheral rim on the end of the arcuate wall forms a continuous extension of the annular flange and the rim on the side wall of the socket adapter housing.
