## Abstract

A crimp terminal (10) has a connecting portion (12) that is conductively connected to an electrical connection target, a crimp portion (14) that is fixed by crimping to a core (58) of a coated wire (56), and a link (16) extending between the connecting portion (12) and the crimp portion (14). The crimp portion (14) has a placement portion (36) on which the core (58) of the coated wire (56) is placed, and a core crimping portion (38) protruding from opposite edges of the placement portion (36). Extended portions (48) are provided on ends of the core crimping portions (38) toward the link (16) and at least one engaging corner (52) is formed on an upper end surface (50) of each of the extended portions (48).

## Claims

### Claim 1

A crimp terminal having opposite front and rear ends, the crimp terminal comprising:
a connecting portion in proximity to the front end and being configured to be connected conductively to an electrical connection target;
a crimp portion rearward of the connecting portion and having a placement portion for receiving a core of a coated wire, core crimping portions protruding from opposite sides of the placement portion and having upper edges remote from the placement portion, the core crimping portions being configured to be crimped into engagement with the core placed on the placement portion;
a link extending between the connecting portion and the crimp portion; and
extended portions extending forward from the core crimping portions, each of the extended portions having an upper edge extending forward from the respective core crimping portions at a height lower than the upper edge of the respective core crimping portion and a front edge extending up from the link, at least one upward and forward pointing engaging corner being formed between the upper and front edges of each of the extended portions.

### Claim 2 (depends on 1)

The crimp terminal of claim 1, wherein the at least one engaging corner on each of the extended portions comprises a plurality of the engaging corners on each of the extended portions in a stepped manner.

### Claim 3 (depends on 1)

The crimp terminal of claim 1, further comprising a reinforcing ridge formed on the link.

### Claim 4 (depends on 3)

The crimp terminal of claim 3, wherein the connecting portion and the crimp portion are spaced apart in a longitudinal direction, the reinforcing ridge extending in the longitudinal direction.

### Claim 5 (depends on 4)

The crimp terminal of claim 4, wherein the reinforcing ridge is in a central section of the link in a width direction that is perpendicular to the longitudinal direction.

### Claim 6 (depends on 1)

The crimp terminal of claim 1, wherein each of the engaging corners is rounded.

### Claim 7 (depends on 1)

The crimp terminal of claim 1, further comprising a covering body covering at least parts of the crimp portion and the link and engaging the engaging corners.

### Claim 8 (depends on 7)

The crimp terminal of claim 7, wherein the covering body is a heat shrinkable tube.

### Claim 9 (depends on 1)

The crimp terminal of claim 1, wherein the extended portions align respectively with in the core crimping portions in a front to rear direction.

### Claim 10 (depends on 1)

The crimp terminal of claim 1, wherein the connecting portion is substantially planar.

### Claim 11 (depends on 10)

The crimp terminal of claim 10, wherein the connecting portion has a through hole passing through a central portion thereof.

### Claim 12 (depends on 10)

The crimp terminal of claim 10, wherein at least a portion of the think is coplanar with the connecting portion.
