Abstract

A data surge protection module can be added to data and control networks not having such surge protection. The use of quick connect/disconnect connectors allows for the rapid installation and/or replacement of such modules. A built-in ground plate and a braided low impedance conductor offer alternative grounding for the module. The module employs two or more diode steering bridges and uses a diode as a surge suppression element.

Claims

1. A data surge protection module for protecting data communication circuits from transient voltage surges coupled to an enclosure, comprising:

a housing;

a printed circuit board having circuit components for conducting a voltage surge located within said housing;

a rigid ground terminal plate coupled at a first end to said printed circuit board and adapted to be coupled at a second end to a grounding stud on the enclosure; and

a flexible low impedance alternate ground wire coupled at a first (one) end to said printed circuit board and adapted to be coupled at a second (the other) end to a grounding stud on the enclosure, wherein said ground terminal plate and said low impedance ground wire are complementary ground connects, and (whereby) at least (one of) said ground terminal plate or said low impedance ground wire is coupled to said groundling stud on the enclosure to provide a ground for said data surge protection module.

2. A data surge protector module, as defined in claim 1, wherein said low impedance ground wire is a braided wire.

3. A data surge protector module, as defined in claim 1, further comprising:

a first multi-conductor connector coupled to a like number of data input conductors; and

a first multi-pin connector, one first pin for each of said data input conductors, each of said first pins coupled to said printed circuit board whereby the joining of said first multi-conductor connector and said first multi-pin connector connects said data input conductors to said printed circuit board.

4. A data surge protector module, as defined in claim 3, wherein said first multi-pin connector is a quick connect, quick disconnect connector.

5. A data surge protector module, as defined in claim 3, further comprising:

a second multi-conductor connector coupled to a like number of data output conductors; and

a second multi-pin connector, one second pin for each of said data output conductors, each of said second pins coupled to said printed circuit board whereby the joining of said second multi-conductor connector and said second multi-pin connector connects said data output conductors to said printed circuit board and said data input conductors.

6. A data surge protection module, as defined in claim 5, wherein said second multi-pin connector is a quick connect, quick disconnect connector.

7. A data surge protection module, as defined in claim 5, wherein both of said first multi-pin and second multi-pin connectors are quick connect, quick disconnect connectors.

8. A data surge protection module, as defined in claim 3, wherein said number of data input conductors is three.

9. A data surge protector module, as defined in claim 8, wherein said number of data output conductors is three.

10. A data surge protection module, as defined in claim 3, wherein said number of data input conductors is six.

11. A data surge protector module, as defined in claim 10, wherein said number of data output conductors is six.
