Abstract

An overlay for a wall jack adapted to receive a telephony plug of a specific type. The overlay comprises a housing, as well as a telephony plug and a telephony socket on opposite faces of the housing. The telephony socket is adapted to receive a telephony plug of the specific type, and is equipped with a first physical lock mechanism for keeping the telephony plug of the specific type connected to the telephony socket. Also provided is a high-speed connector integrated to the housing, for connection to a mating connector leading to a digital apparatus, the high-speed connector being equipped with a second physical lock mechanism for keeping the mating connector connected to the high-speed connector. The second lock mechanism is designed to be more resistant to tension-induced disconnect than the first lock mechanism.

Claims

1. An overlay for a wall jack adapted to receive a telephony plug of a specific type, comprising:

a housing having an interior face and an exterior face;

a telephony plug on the interior face of the housing, the telephony plug suitable for insertion into the wall jack;

a telephony socket integrated to the housing and accessible from the exterior face of the housing, the telephony socket being adapted to receive a telephony plug of the specific type, wherein when receiving the telephony plug of the specific type, the telephony socket providing a resistance to tension-induced disconnect of the telephony plug of the specific type;

a high-speed connector integrated to the housing, for connection to a mating connector leading to a digital apparatus, wherein when connected to the mating connector, the high-speed connector providing a resistance to tension-induced disconnect of the mating connector;

the resistance to tension-induced disconnect of the mating connector being greater than the resistance to tension-induced disconnect of the telephony plug of the specific type;

a combiner-splitter unit electrically connected to the telephony plug, to the telephony socket and to the high-speed connector.

2. The overlay defined in claim 1, wherein the combiner-splitter unit is operative to allow telephony-band signals to be exchanged via the telephony socket, to allow out-of-telephony-band signals to be exchanged via the high-speed connector and to allow composite signals comprising the telephony-band signals and the out-of-telephony-band signals to be exchanged via the telephony socket

3. The overlay defined in claim 1, wherein the wall jack is defined in a plate affixed to an architectural structure by a number of fasteners received in respective receiving areas in the architectural structure, wherein said housing comprises a number of receiving areas at least as great as said number of fasteners and configured to receive a respective number of replacement fasteners that affix both said overlay and the plate to the architectural structure when received in the receiving areas of the architectural structure.

4. The overlay defined in claim 3, wherein the fasteners are screws of a first length and wherein the replacement fasteners are screws of a second length greater than the first length.

5. The overlay defined in claim 4, wherein the number of fasteners and replacement fasteners is both two.

6. The overlay defined in claim 1, wherein the telephony plug is an RJ-11 plug and wherein the telephony socket is an RJ-11 socket.

7. The overlay defined in claim 1, wherein the combiner-splitter unit is passive.

8. The overlay defined in claim 1, wherein the combiner-splitter unit is active and is powered by the telephony plug being inserted into the wall jack when the wall jack is energized.

9. The overlay defined in claim 1, wherein said providing a resistance to tension-induced disconnect of the telephony plug of the specific type comprises hooking onto a tang on the telephony plug of the specific type.

10. The overlay defined in claim 9, wherein said providing a resistance to tension-induced disconnect of the mating connector comprises rotatable securing a nut on one of the high-speed connector and the mating connector.

11. The overlay defined in claim 1, the electrical connection between the combiner-splitter unit, the telephony plug, the telephony socket and the high-speed connector providing for equivalent electrical connectivity between (I) insertion of a telephony plug of the specific type into the telephony socket while the telephony plug is inserted into the wall jack and (II) insertion of a telephony plug of the specific type into the wall jack in the absence of said overlay.

12. The overlay defined in claim 2, wherein the wall jack is defined in a plate affixed to an architectural structure by a number of fasteners received in respective receiving areas in the architectural structure, wherein said housing comprises a number of receiving areas at least as great as said number of fasteners and configured to receive a respective number of replacement fasteners that affix both said overlay and the plate to the architectural structure when received in the receiving areas of the architectural structure.

13. The overlay defined in claim 12, wherein the fasteners are screws of a first length and wherein the replacement fasteners are screws of a second length greater than the first length.

14. The overlay defined in claim 13, wherein the number of fasteners and replacement fasteners is both two.

15. The overlay defined in claim 2, wherein the telephony plug is an RJ-11 plug and wherein the telephony socket is an RJ-11 socket.

16. The overlay defined in claim 2, wherein the combiner-splitter unit is passive.

17. The overlay defined in claim 2, wherein the combiner-splitter unit is active and is powered by the telephony plug being inserted into the wall jack when the wall jack is energized.

18. The overlay defined in claim 2, wherein said providing a resistance to tension-induced disconnect of the telephony plug of the specific type comprises hooking onto a tang on the telephony plug of the specific type.

19. The overlay defined in claim 18, wherein said providing a resistance to tension-induced disconnect of the mating connector comprises rotatably securing a nut on one of the high-speed connector and the mating connector.

20. The overlay defined in claim 2, the electrical connection between the combiner-splitter unit, the telephony plug, the telephony socket and the high-speed connector providing for equivalent electrical connectivity between (I) insertion of a telephony plug of the specific type into the telephony socket while the telephony plug is inserted into the wall jack and (II) insertion of a telephony plug of the specific type into the wall jack in the absence of said overlay.
