Abstract

A socket adapter for converting a conventional bottom connected watthour meter housing to a socket-type watthour meter housing. The adapter includes a housing having a watthour meter receiving portion including a plurality of electrical contacts which removably receive the blade terminals of a watthour meter. The contacts are connected via electrical conductors to terminals mounted in an integral terminal portion of the housing. A cover member is removably mountable over the terminal portion of the housing to provide access to the terminals. The terminal portion and the cover cooperate to form guide surfaces which direct the building conductors into engagement with the terminals within the adapter. A surge protector in the form of a pair of wires embedded within the peripheral surface of the watthour meter receiving portion of the housing are connectable through a connector mounted on the back wall of the housing to earth ground.

Claims

1. A watthour meter socket adapter for mounting a socket-type watthour meter having a plurality of blade type electrical terminals to a building comprising:

a housing, the housing including;

a watthour meter receiving portion;

a plurality of biased electrical contacts mounted within the watthour meter receiving portion for removably receiving the blade type electrical terminals of a socket-type watthour meter in a snap-in connection;

a terminal portion integrally formed with the watthour meter receiving portion;

a plurality of electrical terminals mounted within the terminal portion;

a plurality of electrical conductors connected between the contacts in the watthour meter receiving portion and the terminals in the terminal portion of the housing; and

guide means formed in the terminal portion of the housing for guiding the electrical wiring conductors of the building into engagement with the terminals in the terminal portion of the housing.

2. The watthour meter socket adapter of claim 1 further including:

surge protection means mounted within the housing and connectable to earth ground.

3. The watthour meter socket adapter of claim 1 wherein the guide means comprises:

dividers disposed between each of the individual terminals in the terminal portion and forming slots therebetween;

the terminals being slidably disposed within the slots between the dividers;

each of the dividers having an outer edge inwardly tapered towards the adajcent slot to provide a surface for guiding the building wiring conductors into engagement with the terminals in the housing.

4. The watthour meter socket adapter of claim 3 further including:

a cover removably disposable into engagement with the terminal portion of the housing;

the cover including;

a plurality of spaced dividers formed with complimentary shaped outer, inwardly tapering edges to cooperate in an engaged manner with the dividers on the terminal portion of the housing to form the slots for urging inward the building conductors into engagement with the terminals in the housing.

5. The watthour meter socket adapter of claim 1 further including:

a cover removably engageable with the terminal portion of the housing;

means for slidably attaching the cover to the housing, the attaching means comprising;

complementary formed slot and flange means formed on the watthour meter receiving portion of the housing and the peripheral edges of the cover for removable insertion of the cover into the housing.

6. The watthour meter socket adapter of claim 5 further including:

a removable top;

key means lockably insertable through a portion of the top and engageable with the underlying cover for releasably locking the top to the cover.

7. A watthour meter socket adapter for mounting a socket-type watthour meter to a building comprising:

a housing, the housing including;

a watthour meter receiving portion;

a plurality of electrical contacts mounted within the watthour meter receiving portion for receiving the terminals of a socket-type watthour meter;

a terminal portion integrally formed with the watthour meter receiving portion;

a plurality of electrical terminals mounted within the terminal portion;

a plurality of electrical conductors connected between the contacts in the watthour meter receiving portion and the terminals in the terminal portion of the housing;

guide means formed in the terminal portion of the housing for guiding the electrical wiring conductors of the building into engagement with the terminals in the terminal portion of the housing; and

surge protection means mounted within the housing and connectable to earth ground for protecting the watthour meter from electrical power surges, the surge protection means comprising a pair of wires embedded within the watthour meter receiving portion of the housing and connectable through the housing to earth ground.

8. The watthour meter socket adapter of claim 7 wherein the wires are mounted in the peripheral edge of the watthour meter receiving portion of the housing.

9. A watthour meter socket adapter for mounting a socket-type watthour meter having a plurality of blade type electrical terminals to a building comprising:

a housing, the housing including;

a watthour meter receiving portion;

a plurality of biased electrical contacts mounted within the watthour meter receiving portion for removably receiving the blade type electrical terminals of a socket-type watthour meter in a snap-in connection;

a terminal portion integrally formed with the watthour meter receiving portion;

a plurality of electrical terminals mounted within the terminal portion;

a plurality of electrical conductors connected between the contacts in the watthour meter receiving portion and the terminals in the terminal portion of the housing; and

guide means formed in the terminal portion of the housing for guiding the electrical wiring conductors of the building into engagement with the terminals in the terminal portion of the housing.
