Circuit protection block
A protection block and method of use are disclosed. The protection block includes a rectangular housing having a front, a rear, and top, bottom, left, and right sides. The protection block also includes a plurality of sockets arranged in a two-dimensional array in the front of the housing, each of the plurality of sockets associated with two pairs of opposed, normally open contacts. Each of the plurality of sockets is arranged to receive an overvoltage protection plug that separately connects each of the two pairs of contacts. The protection block also includes a plurality of electrical connections in a second discrete region of the block separate from the first discrete region, the plurality of electrical connections electrically connected to the contacts. The protection block also includes a grounding bar associated with one or more of the sockets and positioned for electrical connection to a ground connection of an overvoltage protection plug when inserted into a socket.

(c) a plurality of electrical connections in a second discrete region of the block separate from the first discrete region, the plurality of electrical connections electrically connected to the contacts;
(d) a grounding bar associated with one or more of the sockets and positioned for electrical connection to a ground connection of an overvoltage protection plug when inserted into a socket.
2. The circuit protection block of claim 1 , wherein the sockets are sized to receive at least a portion of a housing of an overvoltage protection plug.
3. The circuit protection block of claim 1 , wherein the plurality of sockets each are arranged to receive an overvoltage protection plug which is useable in a Krone-style connection block.
4. The circuit protection block of claim 1 , wherein each of the contacts connects to a corresponding pin on the rear of the housing.
5. The circuit protection block of claim 4 , wherein each pin is electrically connected to a corresponding signal wire.
6. The circuit protection block of claim 5 , wherein the pins and signal wires are sealed under a plastic coating on the rear of the protection block.
7. The circuit protection block of claim 1 , wherein the housing is at least partially filled with gel.
8. The circuit protection block of claim 7 , wherein the gel at least partially covers the contacts.
9. The circuit protection block of claim 1 , wherein the grounding bar electrically connects to a grounding plate, the grounding plate electrically connected to a ground connection external to the circuit protection block.
10. The circuit protection block of claim 9 , wherein the grounding bar electrically connects to the grounding plate via a solderless press-fit connection.
11. The circuit protection block of claim 1 , wherein one or more of the plurality of sockets has a keyed shape that dictates an orientation for insertion of the overvoltage protection plug.
12. The circuit protection block of claim 11 , wherein the keyed shape includes an angled corner.
13. The circuit protection block of claim 1 , further comprising at least one mounting protrusion formed on a side of the housing.
14. The circuit protection block of claim 1 , wherein the housing includes a base and a cover, the cover including openings exposing the contacts mounted in the base.
15. The circuit protection block of claim 1 , wherein the rectangular housing is approximately 7.9 inches by approximately 5.8 inches in size.
16. The circuit protection block of claim 1 , wherein the electrical connections are on a rear side of the housing.
17. A protection block comprising:
