## Abstract

The evaluation jig includes a pair of female terminals connectable to a pair of male terminals of a charging connector and an electric wire that connects the paired female terminals to each other. The electric wire has a cross-sectional area of 70 mm2 or more and 95 mm2 or less. The electric wire has a length of 2 m or more.

## Claims

### Claim 1

A reference jig comprising:
a pair of reference terminals each having a front end and a rear end opposite to the front end in a first direction, the front ends being connectable to a pair of male terminals of a connector; and
an electric wire that connects the rear ends to each other, the electric wire extending from the rear ends in the first direction away from the front ends,
the electric wire having a cross-sectional area of 95 mm2,
the electric wire having a length of 1 m or more.

### Claim 2 (depends on 1)

The reference jig according to claim 1, wherein the electric wire is made of copper.

### Claim 3 (depends on 1)

The reference jig according to claim 1, wherein:
each of the pair of reference terminals includes:
a cylindrical portion having an outer peripheral surface, and
a flange having a shape projecting from the outer peripheral surface of the cylindrical portion; and
the electric wire is connected to the flange.

### Claim 4 (depends on 1)

The reference jig according to claim 1, wherein the electric wire and the pair of reference terminals form a U shape.
