Abstract

The present invention proposes a modified connector for a car battery, which comprises a main body and a safety device assembled together. The main body is a conductor having a C-shaped gripper to be gripped on an electrode of the battery. At least a connection hole having inner threads is installed on the main body. The safety device comprises an insulating lagging, two connection terminals installed at two ends of the lagging, and a safety component assembled between the two connection terminals. The safety device uses one of the two connection terminals and one end of the lagging to screw in the corresponding connection hole of the main body such that all safety devices required for all electric wires along with the main body can be concentrated and fixed on the battery. Thereby the safety components in the safety devices can be checked and replaced very conveniently.

Claims

1. A modified connector for a car battery comprising:

a main body being a conductor and having a gripping part, such that it can be gripped on an electrode of the battery, at least a connection hole being disposed on said main body, an inner hole of smaller diameter and an outer hole of larger diameter being formed in said connection hole, and at least a safety device having an insulation lagging, a first connection terminal and a second connection terminal being respectively installed at two ends of said lagging, a safety component cutting off electric power when loading current is too large being assembled between said two connection terminals, said first connection terminal being assembled in said inner hole, one end of said lagging being assembled in said outer hole, the core line of an electric wire being assembled in said second connection terminal.

2. The modified connector for a car battery of claim 1, wherein said inner hole has a first inner thread and said first connection terminal of said safety device has a corresponding first outer thread to be screwed in said inner hole.

3. The modified connector for a car battery of claim 1, wherein a binding ring is installed in said inner hole and has a plurality of incurved resilient plates, which extend axially and are annularly arranged.

4. The modified connector for a car battery of claim 2, wherein said outer hole has a second inner thread and one end of said safety device has a corresponding second outer thread to be screwed in said outer hole.

5. The modified connector for a car battery of claim 1, wherein said safety component of said safety device can be a safety fuse.

6. The modified connector for a car battery of claim 1, wherein said safety component of said safety device can be a circuit breaker.

7. The modified connector for a car battery of claim 1, wherein said gripping part of said main body is a C-shaped gripper matched with a screw.

8. The modified connector for a car battery of claim 1, wherein said second connection terminal of said safety device has a connection hole for the insertion of the core line of the electric wire, and a tightening screw penetrating to said connection hole is installed perpendicularly to said connection hole.

9. The modified connector for a car battery of claim 4, wherein another end of said lagging of said safety device has a third outer thread such that an insulation end cap having an inner thread can be screwed thereon to cover said second connection terminal.
