Abstract

A connection system for allowing access to a primary power signal flowing through a utility meter. The connection system comprises a collar assembly, an adapter assembly, and adapter electronics. The collar assembly comprises a collar housing adapted to engage the wall box and the meter assembly, a plurality of main terminals, a plurality of secondary terminals. The adapter assembly comprises an adapter housing and a plurality of adapter contacts. The adapter housing is sized and dimensioned to be arranged in an engaged position relative to the collar housing. The adapter contacts engage the secondary contacts when the adapter housing is in the engaged position. The adapter electronics are contained within the adapter housing and are electrically connected to the adapter contacts.

Claims

a collar assembly comprising

a collar housing adapted to engage the wall box and the meter assembly,

a plurality of main terminals supported by the collar housing such some of the main terminals engage the box terminals and some of the main terminals engage the meter prongs to allow the primary power signal to flow between the box terminals and the meter prongs, and

a plurality of secondary terminals supported by the collar housing, where the secondary terminals are each electrically connected to at least one of the main terminals such that the primary power signal is present at the secondary terminals;

an adapter housing sized and dimensioned to be arranged in an engaged position relative to the collar housing,

a plurality of adapter contacts, where the adapter contacts engage the secondary contacts when the adapter housing is in the engaged position, and

a lock projection extending from the adapter housing;

a lock ring for selectively securing the meter assembly onto the collar assembly, where the lock projection is arranged such that the lock ring inhibits movement of the adapter housing out of the engaged position; and

adapter electronics contained within the adapter housing, where the adapter electronics are electrically connected to the adapter contacts.

2. A connection system as recited in claim 1, in which:

the collar assembly defines an adapter opening; and

the adapter housing extends at least partly through the adapter opening in the collar housing when the adapter housing is in the engaged position.

3. A connection system as recited in claim 1, further comprising means for inhibiting unauthorized removal of the adapter assembly from the engaged position.

4. A connection system as recited in claim 1, further comprising a lock ring for locking the meter assembly onto the collar assembly to inhibit tampering with the meter assembly.

5. A connection system as recited in claim 4, in which a lock projection extends from the adapter housing, where the lock projection engages the lock ring to inhibit tampering with the adapter housing.

6. A connection system as recited in claim 1, further comprising a guide system for guiding the adapter housing into the engaged position.

7. A connection system as recited in claim 6, in which the guide system comprises an alignment projection formed on one of the collar housing and the adapter housing and an alignment groove formed on the other of the collar housing and the adapter housing.

8. A connection system as recited in claim 1, further comprising an adapter cable electrically connected between the adapter electronics and a remote module.

9. A connection system as recited in claim 1, in which the adapter electronics generates a modified signal based on the primary power signal.

10. A connection system as recited in claim 9, in which:

the primary power signal is an alternating current signal; and

the modified signal is a direct current signal.

11. A connection systems as recited in claim 9, in which the modified signal is an uninterrupted power signal.

12. A connection system as recited in claim 1, in which the adapter electronics alter the flow of the primary power signal between the box terminals and the meter prongs when the primary power signal is not within predetermined parameters.

13. A connection system as recited in claim 12, in which the adapter electronics take the form of a surge protector.

14. A connection system as recited in claim 1, in which an access opening is formed in the adapter housing, where access to the access opening is obstructed by the wall box when the adapter housing is in the engaged position.

15. A connection system as recited in claim 14, in which the adapter assembly further comprises:

a cover member for covering the access opening; and

at least one screw for securing the cover member to the adapter housing, where the at least one screw is substantially inaccessible when the adapter housing is in the engaged position.

16. A method of accessing a primary power signal flowing through a utility meter having a wall box defining box terminals and a meter assembly defining meter prongs adapted to engage the box terminals, the method comprising the steps of:

providing a collar housing adapted to engage the wall box and the meter assembly;

supporting a plurality of main terminals on the collar housing;

supporting a plurality of secondary terminals on the collar housing;

electrically connecting each of the secondary terminals to at least one of the main terminals such that the primary power signal is present at the secondary terminals;

arranging the collar housing between the wall box and the meter assembly such that such some of the main terminals engage the box terminals and some of the main terminals engage the meter prongs to allow the primary power signal to flow between the box terminals and the meter prongs;

providing an adapter housing;

mounting a plurality of adapter contacts on the adapter housing;

containing adapter electronics within the adapter housing;

electrically connecting the adapter electronics to the adapter contacts; and

placing adapter housing in an engaged position relative to the collar housing such that

the adapter contacts engage the secondary contacts, and

the primary power signal is applied to the adapter electronics.

17. A connection system for allowing access to a primary power signal flowing through a utility meter having a wall box defining box terminals and a meter assembly defining meter prongs adapted to engage the box terminals, the connection system comprising:

a collar assembly comprising

a collar housing defining an adapter opening, where the collar housing is adapted to engage the wall box and the meter assembly,

a plurality of main terminals supported by the collar housing such some of the main terminals engage the box terminals and some of the main terminals engage the meter prongs to allow the primary power signal to flow between the box terminals and the meter prongs, and

a plurality of secondary terminals supported by the collar housing, where the secondary terminals are each electrically connected to at least one of the main terminals such that the primary power signal is present at the secondary terminals;

an adapter assembly comprising

an adapter housing sized and dimensioned to be inserted at least partially through the adapter opening in an engaged position relative to the collar housing,

a plurality of adapter contacts, where the adapter contacts engage the secondary contacts when the adapter housing is in the engaged position;

a lock projection extending from the adapter housing;

a lock ring for selectively securing the meter assembly onto the collar assembly, where the lock projection is arranged such that the lock ring inhibits movement of the adapter housing out of the engaged position; and
