Abstract

A telephone line to utility meter interface for use in connecting a telephone line pair to a plurality of utility meters, includes a weather sealed and lockable housing with a telephone line cord plug and receptacle and a terminal block disposed therein. The incoming telephone line pair may be isolated from the utility meters for testing, via the insertion of a known operating telephone having a standard telephone plug into the receptacle within the housing which is integrally molded into the terminal block. The terminal block also includes integrally molded test cable retainer. The utility meters may individually be interrogated by the aid of electrical interrogation circuitry activated by a specific electrical signal appearing on the subscriber telephone line.

Claims

1. A utility meter to telephone line interface comprising:

(a) a hollow housing having a closed end and a major open end;

(b) a cover adapted to cooperate with said housing major open end, said cover being hingedly connected to said housing along one edge of said housing major open end;

(c) a first opening in said housing adapted to receive at least one subscriber telephone line pair and one utility meter line pair;

(d) a removable terminal block disposed within said hollow housing, said terminal block having;

(i) an integrally molded telephone receptacle housing provided with a through opening having a first open end and a second open end, said receptacle housing being adapted to receive and removably retain a mating telephone plug having conductive pins disposed on the distal end of a plug-in telephone line cord having at least two terminals in said first open end and a pin carrier block having a plurality of conductor pins disposed in said second open end, said receptacle housing being adapted to hold said conductor pins in electrically conductive contact with said telephone plug conductive pins when said pin carrier block and said telephone plug are mated,

(ii) connection means for electrically connecting at least two of said receptacle conductor pins to at least a pair of telephone station line terminals disposed on the rear surface of said terminal block adapted to receive said at least one subscriber telephone line pair,

(iii) at least two utility line terminals disposed in said terminal block, said utility line terminals being adapted to receive said at least one utility meter line pair,

(iv) first cable connection means having a plurality of line pairs therein, each one of said line pairs being connected to a pair of utility meter terminals, the other distal ends of said line pairs being connected to a pair of utility line terminals disposed on said terminal block, and

(v) second cable connection means having a plurality of line pairs therein, one end of each of said line pairs being connected to respective pairs of utility terminal pairs, the other end of said second cable connection means terminating in a telephone plug so that when said plug is placed in said receptacle said telephone line pairs are continued; and

(e) a lip having an opening therein extending from an edge of said housing major opening; and

(f) a lip having an opening therein extending from said hinged cover that aligns with said lip opening when said hinged cover is in the closed position.

2. A utility meter to telephone line interface according to claim 1 further including locking means adapted to cooperate with the lip openings provided on said cover and said housing major opening.

3. A utility meter to telephone line interface according to claim 1 further including cooperating weather seal means disposed about the edge of said housing opening and the periphery of said cooperating cover for substantially sealing said housing.

4. A utility meter to telephone line interface according to claim 1 wherein said terminal block further includes:

(a) an L-shaped opening adapted to receive a second cable;

(b) protruding portion means disposed proximate one leg of said L-shaped opening for retaining said second cable, and

(c) a pin carrier block opening, said opening being provided with a plurality of channels adapted to receive a portion of said conductor pins.

5. A utility meter to telephone line interface according to claim 2 further including a pin carrier block, said carrier block including:

(a) a plurality of parallel through apertures adapted to receive said conductor pins therein extending from the front face of said pin carrier block to the rear face of said pin carrier block;

(b) a plurality of parallel channels extending from the front face of said pin carrier block to the rear face of said pin carrier block, said channels being adapted to receive said conductor pins, said conductor pins being adapted to extend beyond said front face when inserted into said through apertures from said rear face of said pin carrier block and extend upwardly out of said apertures and into corresponding channels at approximately 90 degrees and are further bent in a downwardly direction at approximately 45 degrees from said front surface.

6. A utility meter to telephone line interface according to claim 5 further including pictorial indicia disposed on said cover to indicate the position for connecting the lines of each type of utility meter.

7. A utility meter to telephone line interface according to claim 1 further comprising:

(a) interrogation circuit means disposed proximate each utility meter connected between said second cable and each said utility meter for permitting each utility meter to be interrogated one at a time, and

(b) means for activating each said interrogation circuit means upon a specific unique electrical signal appearing upon said at least one subscriber telephone line.
