Abstract

A wall phone adapter is provided which accommodates a variety of removable filter modular units for interconnection between incoming telephone lines connected to a wall mounting plate and subscriber'"'"'s network termination equipment. The wall phone adapter includes a cover housing for receiving snappingly a removable filter modular unit. The removable filter modular unit has an impedance blocking filter circuit mounted thereon. The wall phone adapter further includes upper and lower slidable latches so as to facilitate connections to studs formed on the wall mounting plate which has either a standard studs-spacing or a closer studs-spacing.

Claims

1. A wall phone adapter for interconnection between a wall jack mounted on a wall mounting plate and a wall telephone set, comprising:

a cover housing formed of a front wall member, a top wall member, a bottom wall member and confronting sidewall members;

said top wall member, said bottom wall member, and said confronting sidewall members being formed integrally with said front wall member and extending rearwardly therefrom so as to define a cavity for receiving snappingly a removable filter modular unit;

said removable filter modular unit having an impedance blocking filter circuit mounted therein;

a filtered modular adapter telephone jack mounted in a central portion of said front wall member of said cover housing for receiving a first modular plug connected to a telephone set;

a first filter modular line jack formed on one side of said removable filter modular unit;

a second filter modular phone jack formed on another side of said removable filter modular unit for receiving a second modular plug connected to an answering machine or Fax machine;

a third filter DSL pass-through jack formed also on said another side of said removable filter modular unit for receiving a third modular plug connected to DSL or HPN equipment devices;

a movable line cord having a modular phone plug connected to its one end for insertion into a wall phone jack on a wall phone mounting plate and having a modular filter input plug connected to its other end for insertion into said first filter modular line jack; and

electrical wiring connections operatively coupled between said filter input plug and said adapter telephone jack.

2. A wall phone adapter as claimed in claim 1, further comprising a short pigtail cord being stored in said cover housing, said pigtail cord having a first end connected to a modular plug and having a second end connected to a modular plug.

3. A wall phone adapter as claimed in claim 2, wherein said modular filter unit is removed from said cavity and is usable as an in-line filter by connecting the modular plug on the first end of said pigtail cord into the line jack of said modular filter unit and connecting the modular plug on the second end of said pigtail cord into a wall phone jack connected to incoming telephone lines.

4. A wall phone adapter as claimed in claim 1, wherein said modular filter unit houses either single, dual or triple input impedance blocking filter circuits.

5. A wall phone adapter as claimed in claim 1, further comprising slidable latch means for engaging and locking with studs formed on the wall mounting plate, said slidable latch means being adapted to accommodate both studs with a standard spacing and studs with a closer spacing.

6. A wall phone adapter as claimed in claim 5, wherein said slidable latch means includes an upper slidable latch and a lower slidable latch, each being provided with latching hooks for locking engagement with said respective top and bottom wall members of said cover housing.

7. A wall phone adapter as claimed in claim 6, wherein said lower slidable latch is provided with a first arcuate-shaped slot with bumps for locking engagement with studs of the standard spacing and a second arcuate-shaped slot with bumps for locking engagement with the studs of the closer spacing.

8. A wall phone adapter as claimed in claim 1, wherein a small window opening is formed in the front wall member for allowing visual indication of model number printed on said filter modular unit.

9. A wall phone adapter as claimed in claim 1, wherein said filter modular unit is comprised of a top cover plate, a PCB assembly, and a bottom plate.

10. A wall phone adapter as claimed in claim 9, wherein said top plate is formed with a plurality of retaining posts which mate with retaining holes formed in said bottom plates so as to sandwich the PCB assembly therebetween.

11. A wall phone adapter for interconnection between a wall jack mounted on a wall mounting plate and a telephone set, comprising:

cover housing means;

removable filter modular means disposed within said cover housing means for mounting an impedance blocking filter circuit;

adapter telephone jack means for connection to a telephone set;

filter input means formed on said removable filter modular unit;

filter output means formed on said removable filter modular means for connection to an answering machine and DSL equipment;

movable line cord means for connection between a modular jack connected to incoming telephone line and said filter input means; and

electrical wiring connection means operatively coupled between said filter input means and said adapter telephone jack means.

12. A wall phone adapter as claimed in claim 11, wherein said filter modular means houses either single, dual or triple input impedance blocking filter circuits.

13. A wall phone adapter as claimed in claim 12, wherein a small window opening is formed in said cover housing means for allowing visual indication of model number printed on said filter modular means.

14. A wall phone adapter as claimed in claim 11, wherein said filter modular means is comprised of a top cover plate, a PCB assembly, and a bottom plate.

15. A wall phone adapter as claimed in claim 14, wherein said top plate is formed with a plurality of retaining posts which mate with retaining holes formed in said bottom plates so as to sandwich the PCB assembly therebetween.

16. A wall phone adapter for interconnection between a wall jack mounted on a wall mounting plate and a telephone set, comprising:

cover housing means;

removable filter modular means disposed within said cover housing means for mounting an impedance blocking filter circuit;

adapter telephone jack means for connection to a telephone set;

filter input means formed on said removable filter modular unit;

filter output means formed on said removable filter modular means for connection to an answering machine and DSL equipment;

movable line cord means for connection between a modular jack connected to incoming telephone line and said filter input means;

electrical wiring connection means operatively coupled between said filter input means and said adapter telephone jack means; and

slidable latch means for engaging and locking with studs formed on the wall mounting plate so as to accommodate both studs with a standard spacing and studs with a closer spacing.

17. A wall phone adapter as claimed in claim 16, wherein said slidable latch means includes an upper slidable latch and a lower slidable latch, each being provided with latching hooks for locking engagement with said cover housing means.

18. A wall phone adapter as claimed in claim 17, wherein said lower slidable latch is provided with a first arcuate-shaped slot with bumps for locking engagement with studs of the standard spacing and a second arcuate-shaped slot with bumps for locking engagement with the studs of the closer spacing.

19. A wall phone adapter as claimed in claim 16, wherein said filter modular means is comprised of a top cover plate, a PCB assembly, and a bottom plate.

20. A wall phone adapter as claimed in claim 19, wherein said top plate is formed with a plurality of retaining posts which mate with retaining holes formed in said bottom plates so as to sandwich the PCB assembly therebetween.
