## Abstract

A connector 10 includes a housing 12. A retainer 16 is mounted on the housing 12 from an opening 24 and includes a locking lance 44 facing a cable 14 and resiliently displaceable in one direction toward the cable 14. The locking lance 44 resiliently contacts and holds the cable 14. The locking lance 44 includes a curved portion 60 curved in conformity with an outer surface 30 of the cable 14 and two projections 64 projecting in a direction opposite to the one direction from ends of the curved portion 60. The housing 12 includes a pressing portion 36 to bring the curved portion into surface contact with the outer surface of the cable 14 by pressing the projections 64 in the one direction. A slit 70 is between the projections 64 of the curved portion 60 and extends in an extending direction of the cable 14.

## Claims

### Claim 1

A connector (10), comprising:
a housing (12) including an opening (24) through which a wire (14) is to be inserted; and
a retainer (16) to be mounted on the housing (12), including at least one locking lance (44) disposed to substantially face the wire (14) and resiliently displaceable in one direction toward the wire (14) and configured to hold the wire (14) by the locking lance (44) resiliently contacting the wire (14);
wherein:
the locking lance (44) includes at least one curved portion (60) having a curved shape substantially in conformity with an outer peripheral surface (30) of the wire (14) and at least one projection (64) projecting in a direction opposite to the one direction from the curved portion (60) in a curved direction; and
the housing (12) includes at least one pressing portion (36) configured to resiliently displace the curved portion (60) in the one direction and bring the curved portion (60) into surface contact with the outer peripheral surface (30) of the wire (14) by pressing the pair of projections (60) in the one direction.

### Claim 2 (depends on 1)

The connector of claim 1, wherein the at least one projection comprises two of the projections (64) projecting in a direction opposite to the one direction from both ends of the curved portion (60) in a curved direction.

### Claim 3 (depends on 2)

The connector of claim 2, further comprising a slit (70) between the two projections (64) of the curved portion (60) and extending in an extending direction of the wire (14).

### Claim 4 (depends on 3)

The connector of claim 3, wherein the pressing portion (36) is configured to press the projections (60) in the one direction to resiliently displace the curved portion (60) in the one direction and to bring the curved portion (60) into surface contact with the outer peripheral surface (30) of the wire (14).

### Claim 5 (depends on 1)

The connector of claim 1, wherein the retainer (16) is mounted on the housing (12) from the opening (24).

### Claim 6 (depends on 1)

The connector of claim 1, wherein the pressing portion (36) includes at least one individual pressing portion (38) configured to press the projection (64) in the one direction.

### Claim 7 (depends on 1)

The connector of claim 1, wherein:
the pressing portion (36) projects in a direction opposite to a mounting direction of the retainer (16) and resiliently displaces the curved portion (60) in the one direction by contacting at least one end of the at least one projection (64) in a projecting direction.

### Claim 8 (depends on 7)

The connector of claim 7, wherein the at least one projection (64) has a tapered surface (66) inclined from the end of the at least one projection (64) in the projecting direction toward a surface of the curved portion (60) opposite to a contact surface with the wire (14) in the mounting direction of the retainer (16).

### Claim 9 (depends on 1)

The connector of claim 1, wherein the locking lance (44) and the pressing portion (36) are provided on both sides across the wire (14).

### Claim 10 (depends on 1)

The connector of claim 1, wherein the curved portion (60) comprises at least one sawtooth-like portion (68) having a sawtooth-like cross-section on a portion facing the wire (14).
