## CPC

- H01R 13/582: {the cable being clamped between assembled parts of the housing}
- H01R: ELECTRICALLY-CONDUCTIVE CONNECTIONS; STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS

## Abstract

A connector (10) includes a housing (12) having an opening (24) into which a cable (14) is inserted, and a retainer (16) is mounted on the housing (12) from the side of the opening (24). The retainer (16) includes locking lances (44) that face the cable (14) and are resiliently displaceable toward the cable (14) for holding the cable (14). The housing (12) includes cantilevered pressing portions (36). The pressing portions (36) displace the locking lances (44) toward the cable (14) to bring the locking lances (44) into contact with the cable (14) by pressing the locking lances (44) toward the cable (14). The retainer (16) includes displacement preventing portions (72) to prevent displacements of the pressing portions (36) in directions opposite to contacting directions with the locking lances (44) by contacting the pressing portions (36) in the directions toward the cable (14).

## Claims

### Claim 1

A connector (10), comprising:
a housing (12) including an opening (24) into which a wire (14) at least partly is to be inserted; and
a retainer (16) to be mounted on the housing (12) from the opening side, the retainer (16) including at least one locking lance (44) disposed to substantially face the wire (14) and resiliently displaceable substantially toward the wire (14), the retainer (16) holding the wire (14) by the locking lance (44) resiliently contacting the wire (14);
wherein:
the housing (12) includes at least one cantilevered pressing portion (36);
the pressing portion (36) resiliently displaces the locking lance (44) substantially toward the wire (14) to resiliently bring the locking lance (44) into contact with the wire (14) by pressing the locking lance (44) substantially in a direction toward the wire (14); and
the retainer (16) includes at least one displacement preventing portion (72) configured to prevent a displacement of the pressing portion (36) in a direction substantially opposite to a contacting direction with the locking lance (44) by contacting the pressing portion (36) substantially in the direction toward the wire (14).

### Claim 2 (depends on 1)

The connector of claim 1, wherein the locking lance (44) is to be brought into surface contact with the wire (14).

### Claim 3 (depends on 1)

The connector of claim 1, wherein a contact surface of the locking lance (44) with the wire (14) has a curved shape substantially in conformity with an outer peripheral surface (30) of the wire (14).

### Claim 4 (depends on 1)

The connector of claim 1, wherein at least one projection (64) projects on a surface of the locking lance (44) substantially facing the pressing portion (36).

### Claim 5 (depends on 4)

The connector of claim 4, wherein the pressing portion (36) of the housing (12) projects in a direction substantially opposite to a mounting direction of the retainer (16) and resiliently displaces the locking lance (44) toward the wire (14) by pressing an end part of the projection (64) substantially in a projecting direction.

### Claim 6 (depends on 4)

The connector of claim 4, wherein the projection (64) has at least one tapered surface (66) inclined toward the facing surface of the locking lance (44) in the mounting direction of the retainer (16) from the end part of the projection (64) in the projecting direction.

### Claim 7 (depends on 1)

The connector of claim 1, wherein two of the locking lances (44) and two of the displacement preventing portions (72) of the retainer (16) and two of the pressing portions (36) of the housing (12) are provided across the wire (14).

### Claim 8 (depends on 7)

The connector of claim 7, wherein both ends of the displacement preventing portions (72) are coupled by two coupling portions (74).

### Claim 9 (depends on 8)

The connector of claim 8, wherein the coupling portions (74) are provided substantially across the wire (14).

### Claim 10 (depends on 8)

The connector of claim 8, wherein the coupling portions (74) include two projections (76) projecting in directions intersecting resilient displacing directions of the locking lances (44) from surfaces facing the wire (14); and
end parts of the projections (76) are to be brought respectively in contact with the wire (14).
