Abstract

A multipurpose wire connection device includes a base plate, a conductive plate, a wire fixation screw, a fireproof box, a support, and a dustpan-shaped housing. The support is disposed on the base plate. The fireproof box includes a rear panel, a bottom panel, two side panels, and an inserted plate. The wire fixation screw is mounted on the conductive plate. The housing is fixed on the bottom plate by a housing fixing screw. The multipurpose wire connection device prevents sparking and red burning of a ground screw when lightning current passes therein, due to corroded contact in long-term exposure to wind and rain. It avoids fire and explosion accidents. It avoids screw corrosion and facilitates ground resistance measurement. The multipurpose wire connection device can also be used for electrical relay, division, and branching. It prevents fire, explosion, rain intrusion, and rust development. It is easy to disassemble.

First claim

What is claimed is:

1. A multipurpose wire connection device comprising:
a base plate, a conductive plate, a wire fixation screw, a fireproof box, a support, and a housing, wherein the base plate includes fixation holes, and support and base plate washers; the base plate has folded peripheries;
wherein the fireproof box includes a piece of back plate, a bottom plate, two side plates, and an inserted plate; the fireproof box is a box with an open top; the back plate includes fixation holes for the fireproof box;
wherein fixation screws are used to affix the fireproof box to the support;
wherein the side plates include receiving grooves for receiving the inserted plate;
wherein the conductive plate includes holes for wire fixation screws and holes for affixing the conductive plate;
wherein the conductive plate includes wire fixation screws, conductive plate fixation screws affixing the conductive plate to a shield plate; and
wherein the housing has a shape of a dustpan, the housing using fixation screws to attach onto the base plate.

2. The multipurpose wire connection device of claim 1 , wherein there is one or more of the wire fixation screw.

3. The multipurpose wire connection device of claim 1 , wherein there is one or more of the fireproof box, conductive plate, and support.

4. A multipurpose wire connection device, comprising:
a base plate attached onto a fixation surface;
a fireproof box affixed onto the base plate; wherein the fireproof box is filled with a fireproof material;
a conductive plate affixed in the fireproof box and buried in the fireproof material, wherein the conductive plate carries a wire fixation screw affixing a conductive wire onto the conductive plate; and
a housing covering the fireproof box.

5. The multipurpose wire connection device of claim 4 , wherein the fireproof box is affixed onto the base plate via a support spacing the fireproof box from the base plate.

6. The multipurpose wire connection device of claim 5 , wherein the conductive wire passes between the base plate and the fireproof box and is bent into the fireproof box.

7. The multipurpose wire connection device of claim 4 , wherein the fireproof box further comprises a shield plate extending from side panels of the fireproof box to provide a fastening surface for affixing the conductive plate thereon.

8. The multipurpose wire connection device of claim 7 , wherein each of the side panels of the fireproof box further comprises a receiving groove for receiving an end panel in forming the fireproof box.

9. The multipurpose wire connection device of claim 4 , wherein the housing prevents rain, dust, or both, from entering the fireproof box.

10. The multipurpose wire connection device of claim 4 , wherein the housing comprises an opening for the conductive wire to enter the multipurpose wire connection device.

11. The multipurpose wire connection device of claim 4 , wherein the conductive plate carries additional wire fixation screws.

12. The multipurpose wire connection device of claim 4 , further comprising additional fireproof boxes, each additional fireproof box having a corresponding conductive plate, for connections with additional conductive wires.

13. The multipurpose wire connection device of claim 4 , wherein the fireproof material is silicon dioxide sand, ordinary sand, earth soil, or a mixture thereof.

14. The multipurpose wire connection device of claim 4 , wherein the conductive plate is made of copper or aluminum.
