Abstract

A connector (10) includes a retainer (30) made of synthetic resin for mounting in a housing (11) at a partial locking position for permitting the insertion of a terminal fitting (20) into the housing (11) and at a full locking position for retaining the inserted terminal fitting (20). Locks (16, 35) are formed on the housing (11) and the retainer (30) and are engageable to hold the retainer (30) at the partial locking position. A pressure receiving surface (15) is formed on the housing (11) and is configured to restrict a movement of the retainer (30) toward the full locking position by pressing the retainer (30) in directions intersecting a moving direction of the retainer (30) from the partial locking position to the full locking position when the retainer (30) is at the partial locking position.

Claims

1. A connector, comprising:

a housing;

at least one terminal fitting to be inserted into the housing;

a retainer mounted in the housing at a partial locking position for permitting insertion of the terminal fitting into the housing and movable to a full locking position for retaining the terminal fitting in the housing;

locking means formed on the housing and the retainer and engageable with one another for holding the retainer at the partial locking position; and

pressing means formed on the housing and the retainer and pressing against each other in directions intersecting a moving direction of the retainer from the partial locking position to the full locking position when the retainer is at the partial locking position for restricting a movement of the retainer toward the full locking position.

2. The connector of claim 1, wherein the pressing means comprises a full locking projection on the retainer, the full locking projection being configured to engage the housing to hold the retainer at the full locking position.

3. The connector of claim 2, wherein the retainer has a main body with at least one retaining portion for engaging the terminal fitting and retaining the terminal fitting in the housing, a narrow portion projecting from the main body and having a smaller width than the main body in a direction substantially parallel to pressing directions of the pressing means, at least part of the pressing means being formed on the narrow portion.

4. The connector of claim 3, wherein the locking means comprises a first locking structure defined by at least one partial locking recess on the main body of the retainer and at least one locking claw on the housing and a second locking structure defined by a partial locking projection on the narrow portion of the retainer and a locking edge on the housing.

5. The connector of claim 4, wherein the partial locking projection is on a side of the narrow portion of the retainer, and wherein the part of the pressing means formed on the narrow portion is on a side of the narrow portion opposite the locking projection.

6. The connector of claim 1, wherein the housing is made of synthetic resin.

7. The connector of claim 1, wherein the retainer is made of synthetic resin.

8. A connector, comprising:

a housing;

at least one terminal fitting to be inserted into the housing;

a retainer mounted in the housing at a partial locking position for permitting insertion of the terminal fitting into the housing and movable to a full locking position for retaining the terminal fitting in the housing;

at least one locking structure formed on the housing and at least one mating locking structure formed on the retainer, the locking structure and the mating locking structure being engageable with one another along a moving direction of the retainer from the partial locking position to the full locking position for holding the retainer at the partial locking position; and

a projection formed on the retainer and configured for pressing against a surface of the housing in a pressing direction intersecting a moving direction of the retainer from the partial locking position to the full locking position when the retainer is at the partial locking position for restricting a movement of the retainer toward the full locking position.

9. The connector of claim 8, wherein the projection is a full locking projection configured to engage the housing along a moving direction of the retainer from the full locking position to the partial locking position for holding the retainer at the full locking position.

10. The connector of claim 8, wherein the retainer has a main body with at least one retaining portion for engaging the terminal fitting and retaining the terminal fitting in the housing, a narrow portion projecting from the main body and having a smaller width than the main body in a direction substantially parallel to the pressing direction of the projection, the projection being formed on the narrow portion.

11. The connector of claim 10, wherein the at least one locking structure on the housing comprises at least one locking claw and a locking edge, and wherein the at least one mating locking structure comprises at least one partial locking recess on the main body of the retainer that engages the locking claw on the housing when the retainer is at the partial locking position and a partial locking projection on the narrow portion of the retainer that engages locking edge on the housing when the retainer is at the partial locking position.

12. The connector of claim 11, wherein the partial locking projection is on a side of the narrow portion of the retainer and the projection is on a side of the narrow portion opposite the locking projection.
