Abstract

An electricity meter transponder package includes an electricity meter and a cover for containing the meter. The cover is secured to the meter by a predetermined rotation of the cover with respect to the meter. A first electrical connector-half is fixedly mounted with respect to the meter, that connector-half having terminals electrically connected to the meter. A second electrical connector-half having terminals mateable with the terminals of the first connector-half is fixedly mounted with respect to the cover in a position such that the predetermined rotation of the cover with respect to the meter causes the terminals of the first and second connector-halves to mate to complete electrical connection between their respective terminals. At least one electrical circuit is carried by the cover, which circuit is electrically connected to at least some terminals of the second connector-half. Securing of the cover to the meter results in automatic electrical connection between the meter and the circuit carried by the cover.

Claims

1. An electricity meter transponder package comprising:

an electricity meter assembly including an electricity meter such as a watthour mounted on a meter base and having terminals for connection to a circuit having a variable such as watthours to be measured;

a cover having an open end and an inner recess for receiving the meter assembly, said cover being securable to the meter assembly to protect the meter assembly from environmental factors such as rain, dust and the like, a predetermined relative movement of the cover with respect to the meter assembly being required to secure the cover to the assembly;

a first electrical connector-half fixedly mounted with respect to the meter assembly, said connector-half having terminals electrically connected to the meter assembly;

a second electrical connector-half having terminals mateable with the terminals of the first connector-half, said second connector-half being fixedly mounted with respect to the cover in a position such that the predetermined relative movement of the cover with respect to the meter assembly causes the terminals of the first and second connector-halves to mate to complete electrical connection between their respective terminals; and

at least one electrical circuit carried by the cover, said circuit being electrically connected to at least some terminals of the second connector-half, whereby securing of the cover to the meter assembly results in automatic electrical connection between the meter assembly and the circuit carried by the cover;

said predetermined relative movement required to secure the cover to the meter assembly being a rotation, said second connector-half being carried by the cover as said cover is rotated with respect to the meter assembly so that the corresponding relative motion of the two connector-halves varies from linear motion as the cover is rotated to secure the cover to the meter assembly, the terminals of at least one of the electrical connector-halves being mechanically floating throughout a predetermined range of movement so that variation of the relative movement of the electrical connector-halves from true linear motion as the cover is rotated with respect to the meter assembly is accommodated by floating of said terminals.

2. An electricity meter transponder package comprising:

an electricity meter such as a watthour having a first electrical connector-half fixedly mounted with respect to the meter, said connector-half having terminals electrically connected to the meter, said meter also having terminals for connection to a circuit having a variable such as watthours to be measured;

a cover having an open end and an inner recess for receiving the electricity meter to protect said meter, a predetermined relative rotational movement of the cover with respect to the meter being required to secure the cover to the meter;

a second electrical connector-half having terminals mateable with the terminals of the first connector-half, said second connector-half being fixedly mounted with respect to the cover in a position such that the predetermined relative rotational movement of the cover with respect to the meter causes the terminals of the first and second connector-halves to mate to complete electrical connection between their respective terminals;

the terminals of at least one of the electrical connector-halves being mechanically floating throughout a predetermined range of movement so that variations of the relative rotational movement of the electrical connector halves from true linear motion as the cover is rotated with respect to the meter is accommodated by floating of the terminals; and

at least one electrical circuit carried by the cover, said circuit being electrically connected to at least some terminals of the second connector-half, whereby securing of the cover to the meter results in automatic electrical connection between the meter and the circuit carried by the cover.

3. The electricity meter transponder package as set forth in claim 2 wherein the first connector-half is disposed along the periphery of the meter and the second connector-half is secured to the linear wall of the cover.

4. The electricity meter transponder package as set forth in claim 2 wherein the at least one electrical circuit carried by the cover and electrically connected to at least some of the terminals of the second connector-half is mounted on a pair of circuit boards, said circuit boards being secured to and separated by a plate, said plate being secured to the cover to fix the pair of circuit boards in place with respect to the cover.

5. The electricity meter transponder package as set forth in claim 2 wherein the meter includes a rotating disk operatively connected to the meter assembly to rotate as a function of the variable being measured by the meter assembly, the rotation of the disk representing the variable being measured by the meter, further including sensing means secured to the meter adjacent the disk for sensing rotation of the disk, said sensing means being electrically connected to the first connector-half to supply measurement information to the electrical circuit carried by the cover when the two connector-halves are connected.

6. The electricity meter transponder package as set forth in claim 5 wherein the cover also carries a power supply circuit connected to the second connector-half, power from said power supply circuit being supplied to the sensing means when the two connector-halves are connected.
