## Abstract

A terminal fitting to be connected to a mating terminal fitting with a tab (T) includes a rectangular tube (11) composed of a bottom wall (12), two side walls (13) rising from the bottom wall (12) and a ceiling wall (15) facing the bottom wall (12). A resilient contact (21) extends along the bottom wall (12) inside the rectangular tube (11). A protection wall (31, 131) has bending edge (L1) continuous with one of the side walls (13) is before a front end (12A) of the bottom wall (12) and extends from the bending edge (L1) toward the other side wall (13). A clearance for receiving the tab (T) is between the protection wall (31, 131) and the ceiling wall (15). The bending edge (L1) approaches the ceiling wall (15) from a front end (12A) of the bottom wall (12) toward a front end (13A) of the side wall (13).

## Claims

### Claim 1

A terminal fitting to be connected to a mating terminal fitting with a tab, comprising:
a rectangular tube extending in forward and backward directions, the rectangular tube having a bottom wall with a front end, first and second side walls projecting substantially perpendicularly from the bottom wall and portions of the first and second side walls extending forward of the front end of the bottom wall, and a ceiling wall continuous from at least one of the side walls and facing the bottom wall,
a resilient contact piece arranged along the bottom wall inside the rectangular tube; and
at least one protection wall continuous with at least one of the side walls a bending edge provided between the at least one protection wall and the at least one of the side walls, the bending edge extending from the front end of the bottom wall towards a front edge of the side wall and arranged to approach the ceiling wall, the at least one protection wall bent at the bending edge toward the other side wall so that the at least one protection wall is disposed forward of the front end of the bottom wall, and a clearance for allowing the entrance of the tab provided between the protection wall and the ceiling wall.

### Claim 2 (depends on 1)

The terminal fitting of claim 1, wherein the at least one protection wall comprises first and second protection walls provided respectively on the first and second side walls.

### Claim 3 (depends on 2)

The terminal fitting of claim 2, wherein the bending edge is straight and connects the front end of the bottom wall and the front end edge of the side wall.

### Claim 4 (depends on 1)

The terminal fitting of claim 1, wherein the bending edge extends obliquely to the bottom wall.
