## Abstract

It is aimed to provide a connector capable of improving a force for holding a terminal fitting by a locking lance. A connector (10) is provided with a housing (20), a terminal locking portion (50) defining a cavity (70) together with the housing (20), and a terminal fitting (90) to be arranged in the cavity (70). The terminal locking portion (50) includes a locking lance (51) for locking the terminal fitting (90). The locking lance (51) is provided on one side surface of the cavity (70) resiliently deformably in a direction intersecting a width direction of the side surface. The housing (20) and the terminal locking portion (50) are made of mutually different materials.

## Claims

### Claim 1

A connector, comprising:
a housing;
a plurality of terminal locking portions defining a plurality of cavities together with the housing; and
a plurality of terminal fittings arranged in the plurality of cavities, respectively,
wherein each of the plurality of terminal locking portions includes a locking lance configured to lock one of the plurality of terminal fittings,
the locking lance is provided on one side surface of one of the plurality of cavities resiliently deformably in a direction intersecting a width direction of the side surface of the cavity,
the housing and each of the plurality of terminal locking portions are made of mutually different resin materials,
wherein the plurality of terminal locking portions is provided corresponding to the plurality of cavities, and
each of the plurality of terminal locking portions includes a pair of fixing portions that project in opposite directions in a width direction of the locking lance so as to be locked to the housing.

### Claim 2 (depends on 1)

The connector of claim 1, wherein the housing is a primary molded portion made of a primary resin material and each of the plurality of terminal locking portions is a secondary molded portion made of a secondary resin material.

### Claim 3 (depends on 1)

The connector of claim 1, wherein a width of the locking lance is set to be equal to that of the cavity.

### Claim 4 (depends on 1)

The connector of claim 1, wherein each of the plurality of terminal locking portions includes a fixing portion locked to the housing in a direction intersecting the width direction of the locking lance.

### Claim 5 (depends on 4)

The connector of claim 4, wherein a pair of the fixing portions project on both sides in the width direction of the locking lance.

### Claim 6 (depends on 1)

The connector of claim 1, wherein the housing and the plurality of terminal locking portions are integrally formed by two-color molding.

### Claim 7

A connector, comprising:
a housing;
a terminal locking portion defining a cavity together with the housing;
a terminal fitting arranged in the cavity; and
the terminal locking portion including a locking lance configured to lock the terminal fitting,
wherein the locking lance is provided on one side surface of the cavity resiliently deformably in a direction intersecting a width direction of the side surface of the cavity,
the housing and the terminal locking portion are made of mutually different resin materials,
the terminal locking portion includes a fixing portion locked to the housing in a direction intersecting a width direction of the locking lance, and
a pair of the fixing portions project on both sides in the width direction of the locking lance.
