Terminal block for interconnection of DPGS power and communications via meter collar
Technologies are generally described for a pocket junction box system. In an example, a pocket junction box is configured to fit inside a meter collar. The pocket junction box includes a first set of electrical terminals on a rear surface of the pocket junction box for interfacing with wire leads inside the meter collar, and a second set of electrical terminals on a front surface of the pocket junction box for interfacing with field wire leads outside the meter collar. The pocket junction box may further include at least one current transducer and at least one microprocessor for monitoring the power flow through the pocket junction box. A front casing is attached to the front surface of the pocket junction box and connected to the second set of electrical terminals. The front casing may include a communications circuit board for communicating with a meter data management system.
1. A system, comprising:
a pocket junction box that fits inside a meter collar, wherein the pocket junction box includes:
a first set of electrical terminals on a rear surface of the pocket junction box for interfacing with wire leads connected to busbars inside the meter collar,
a second set of electrical terminals on a front surface of the pocket junction box for interfacing with field wire leads outside the meter collar,
at least one current transducer, and
at least one microprocessor for monitoring the output of the at least one current transducer to measure the power flow through the pocket junction box; and
a front casing attached to the front surface of the pocket junction box and connected to the second set of electrical terminals.
2. The system of claim 1 , further comprising:
a rear cover for covering the rear surface of the pocket junction box; and
a front cover for covering a front surface of the front casing.
3. The system of claim 2 , wherein the front cover includes a tamper resistant seal.
4. The system of claim 1 , further comprising a gasket that forms a weatherproof seal between the pocket junction box and the front casing.
5. The system of claim 1 , wherein the second set of electrical terminals includes a data contact terminal.
6. The system of claim 1 , wherein the front casing includes a communications circuit board for communicating with a meter data management system.
7. The system of claim 6 , wherein the communications circuit board can be removed while the system is connected to active electrical voltage and replaced with a second communications circuit board.
8. The system of claim 1 , wherein the front casing includes an externally exposed socket to receive an electrical and/or data plug.
9. A pocket junction box that fits inside a meter collar, comprising:
a first set of electrical terminals on a rear surface of the pocket junction box for interfacing with wire leads connected to busbars inside the meter collar;
a second set of electrical terminals on a front surface of the pocket junction box for interfacing with field wire leads outside the meter collar;
at least one current transducer; and
at least one microprocessor for monitoring the output of the at least one current transducer to measure the power flow through the pocket junction box.
10. The pocket junction box of claim 9 , wherein the second set of electrical terminals includes a data contact terminal.
11. The pocket junction box of claim 10 , wherein the data contact terminal communicates with a meter data management system.
12. A meter collar, comprising:
a pocket junction box positioned inside the meter collar, wherein the pocket junction box includes:
a first set of electrical terminals on a rear surface of the pocket junction box coupled to busbars inside the meter collar,
a second set of electrical terminals on a front surface of the pocket junction box for interfacing with field wire leads outside the meter collar,
at least one current transducer, and
at least one microprocessor for monitoring the output of the at least one current transducer to measure the power flow through the pocket junction box; and
a front casing attached to the front surface of the pocket junction box and connected to the second set of electrical terminals.
13. The meter collar of claim 12 , wherein the second set of electrical terminals includes a data contact terminal.
14. The meter collar of claim 12 , wherein the front casing includes a communications circuit board for communicating with a meter data management system.
15. The meter collar of claim 12 , further comprising:
a rear cover for covering the rear surface of the pocket junction box; and
a front cover for covering a front surface of the front casing.
16. The meter collar of claim 15 , wherein the front cover includes a tamper resistant seal.
17. The meter collar of claim 12 , further comprising a gasket that forms a weatherproof seal between the pocket junction box and the front casing.
