Abstract

A power distribution outlet with a fuse, having a battery connector, a connecting block, a distributing block, an insulation plate, a fuse, and an insulation housing is disclosed. The battery connector is connected to the electrode of the battery. The connecting block has a wire to electrically connect the battery connector. The distributing block has a plurality of wire inlets for connecting a plurality of power cords. The connecting block and the distributing block are fixed on an insulation plate and insulated to each other thereby. The fuse electrically connects the connecting block and the distributing block, which are enclosed in the insulation housing. The above structure allows multiple power cords to be conducted with the battery at the same time, while the fuse can be easily inspected and replaced to protect the electronic products connected to the power cords, and the structure is easily fabricated.

Claims

1. A power distribution outlet, to connect an electrode of a battery to a plurality of power cords, comprising:

a battery connector, having a clip portion and a plurality of wire inlets, wherein the clip portion is used to connect the electrode of the battery;

a connecting block, having a joining surface, a first electrode portion, a wire inlet, and a wire having one end fixed in the second wire inlet and the other end connected to one of the wire inlets of the battery connector;

a distributing block, having a connecting surface, a second electrode portion and a plurality of wire inlets, wherein the connecting surface is conformal to the joining surface, the second electrode portion is aligned with the first electrode portion, and the wire inlets are used to receive the power cords;

an insulation plate, to fix the connecting block and the distributing block into a single body thereon, so as to insulate the connecting block from the distributing block;

a fuse, having two conductive parts coupled to the connecting block and the connecting block respectively, so as to conduct the connecting block with the distributing block; and

an insulation housing, to enclose the connecting block and the distribution block therein.

2. The power distribution outlet according to claim 1, wherein each of the wire inlets comprises a pressing screw.

3. The power distribution outlet according to claim 1, wherein the joining surface comprises two inwardly inclined planes merged each other from two sides.

4. The power distribution outlet according to claim 1, wherein the joining surface comprises a single plane.

5. The power distribution outlet according to claim 1, wherein the first electrode portion includes a circular hole formed on the joining surface and a conductive splint installed therein, and the second electrode portion includes a slot penetrating through the distributing block and aligned with the circular hole, such that the first and second electrode portions are merged into a single hole allowing the fuse inserted therethrough, and the second electrode portion further comprising a terminal cap, the terminal cap is a conductor, such that the connecting block and the distributing blocks are conducted via the fuse, the terminal cap and the conductive splint.

6. The power distribution outlet according to claim 5, wherein the distribution block further comprises a window aligned over the second electrode portion.

7. The power distribution outlet according to claim 1, wherein the insulation housing comprises a plurality of stop blocks at a bottom edge thereof to snap with the insulation plate, so as to enclose the connecting and distributing blocks therein, the insulation housing further comprises an opening at a position where the fuse is inserted in the distribution block, and an opening at a position wherein the power cords are plugged in.

8. The power distribution outlet according to claim 1, wherein the insulation plate includes a base and a sheet extending upwardly from the base, the sheet is conformal to the joining surface and the distributing surface, such that the connecting block and the distributing block are fixed adjacent to two opposite sides of the sheet on the base.

9. The power distribution outlet according to claim 1, wherein the connecting block and the distributing block are fixed on the base via a plurality of screws.

10. The power distribution outlet according to claim 1, wherein the first and second electrode portions include slots allowing the fuse to plug in, so as to electrically connect the connecting block and the distributing block.

11. The power distribution outlet according to claim 1, wherein the first and second electrode portions include threaded holes allowing the fuse to be threaded in, so as to electrically connect the connecting block and the distributing block.
