## Abstract

A water stopping apparatus for causing a water stopping material to penetrate exposed core wires of a sheathed wire forming a wire harness includes a pair of dies which can abut against each other in a mutually opposed condition, thereby forming a pressurizing space in which an exposed portion of the core wires of the wire harness can be mounted, a filling portion for filling a water stopping material in the pressurizing space in which the exposed portion of the core wires is mounted, and a pressurizing portion for supplying pressurized gas into the pressurizing space to pressurize the same.

## Claims

### Claim 1

A water stopping method of causing a water stopping material to penetrate exposed core wires of a sheathed wire forming a wire harness, the method comprising:
arranging a portion of the wire harness between a pair of dies opposed to each other;
holding the portion of the wire harness between the pair of dies to seal an exposed portion of the core wires arranged within a pressurizing space formed between the dies;
filling the water stopping material in the pressurizing space; and
pressurizing the interior of the pressurizing space.

### Claim 2 (depends on 1)

The water stopping method according to claim 1, wherein after the pressurizing process, the excess water stopping material within the pressurizing space is discharged.

### Claim 3 (depends on 1)

The water stopping method according to claim 1, wherein before the sealing process, a terminal is press-clamped to the exposed portion of the core wires of the sheathed wire.

### Claim 4 (depends on 3)

The water stopping method according to claim 3, wherein in the sealing process, the terminal is arranged within the pressurizing space, and other portion of the terminal than the portion thereof press-clamped to the exposed portion of the core wires is hermetically sealed.

### Claim 5 (depends on 4)

The water stopping method according to claim 4, wherein a sealing material is adhered to the other portion of the terminal than the portion thereof press-clamped to the exposed portion of the core wires to hermetically seal the other portion.

### Claim 6 (depends on 1)

A wire harness wherein with a water stopping method as defined in claim 1, the water stopping of the exposed portion of the core wires to which the terminal is press-clamped is effected by the water stopping material.

### Claim 7

A water stopping apparatus for causing a water stopping material to penetrate exposed core wires of a sheathed wire forming a wire harness, comprising:
a pair of dies which is configured to form a pressurizing space in which an exposed portion of the core wires of the wire harness is mounted when the pair of dies abut against each other in a mutually opposed condition;
a filling portion which fills the water stopping material in the pressurizing space in which the exposed portion of the core wires is mounted; and
a pressurizing portion which supplies pressurized gas into the pressurizing space to pressurize.

### Claim 8 (depends on 7)

The water stopping apparatus according to claim 7, further comprising a discharge portion which discharges the excess water stopping material within the pressurizing space.

### Claim 9 (depends on 7)

The water stopping apparatus according to claim 7, wherein a terminal is press-clamped to the exposed portion of the core wires, and the apparatus further comprises a sealing material which is adhered to other portion of the terminal than the portion thereof press-clamped to the exposed portion of the core wires to hermetically seal the other portion.

### Claim 10 (depends on 7)

The water stopping apparatus according to claim 7, wherein a positioning pin for passing through a fixing hole formed in a terminal press-clamped to the exposed portion of the core wires is formed on one of the pair of dies.
