## Abstract

A clamp for connecting the poles of a battery is disclosed, the clamp being made by shearing and cold-pressing a tinned galvanized brass plate, to reduce environmental pollution with respect to conventional diecast lead alloy clamps.

## Claims

### Claim 1

A battery terminal clamp assembly for storage batteries, said clamp being designed for clamping either a negative pole or a positive pole of said storage battery and being adapted to be used either as a right or a left clamp assembly, said clamp being made in a single piece by shearing and cold-pressing a brass material, said clamp comprising a clamping portion designed for clamping only a copper material of an electric cable to be clamped, said clamping portion having a longitudinal axis substantially coinciding with a longitudinal axis of said clamp assembly, said clamp assembly comprising moreover two cross-wise lugs through each of which is defined a throughgoing hole for receiving therein up to four auxiliary cables.

### Claim 2 (depends on 1)

A clamp assembly according to claim 1, said clamp being made of a tinned brass material.

### Claim 3 (depends on 1)

A clamp assembly according to claim 1, said clamp being made of a tinned galvanized brass material.

### Claim 4 (depends on 1)

A clamp assembly according to claim 1, said clamp being made of 0T67 or 0T70 brass material according to the UNI 4894 Standard.

### Claim 5 (depends on 1)

A clamp assembly according to claim 1, in which said electric cable has a cross-section of substantially 10 to 35 mm.sup.2.

### Claim 6 (depends on 1)

A clamp assembly according to claim 1, in which said clamping portion is so raised as to allow said electric cable to pass through a top portion of said storage battery.
