Abstract

A connector includes: a housing having a lock portion; and a fitting assuring component attached to the housing and detecting whether the housing and the counterpart housing being fitted with each other. The fitting assuring component has a hollow portion to house at least part of the lock portion to surround the at least part of the lock portion upon the fitting assuring component being located at the preset attachment position, and the fitting assuring component preventing the lock portion from switching to cancellation of the state of the housing and the counterpart housing being fitted with each other by interfering with an inside wall of the hollow portion.

Claims

1. A connector comprising:

a housing having a lock portion capable of switching between keeping and cancellation of a state of the housing and a counterpart housing being fitted with each other; and

a fitting assuring component attached to the housing and detecting whether the housing and the counterpart housing being fitted with each other by being prevented from interfering with the lock portion and attached at a preset attachment position upon the housing and the counterpart housing being fitted with each other,

the fitting assuring component having a hallow portion to house at least part of the lock portion to surround the at least part of the lock portion upon the fitting assuring component being located at the preset attachment position, and the fitting assuring component preventing the lock portion from switching to cancellation of the state of the housing and the counterpart housing being fitted with each other by interfering with an inside wall of the hollow portion,

2. The connector according to claim 1, wherein

the lock portion is a cantilever-shaped lock arm switching between keeping and cancellation of the state of the housing and the counterpart housing being fitted with each other by deforming in a preset bending direction;

and

the inside wall of the hollow portion having;

one portion facing the lock portion on one side in the bending direction upon the fitting assuring component being in the preset attachment position;

the other portion facing the lock portion on the other side in the bending direction; and

an interference portion between the one portion and the other portion and preventing the lock portion from deforming to cancel the state of the housing and the counterpart housing being fitted with each other.

3. The connector according to claim 1, wherein

the housing having:

a cantilever-shaped lock piece capable of deforming elastically in a direction to separate from the fitting assuring component; and

a lock projection provided in the lock piece and preventing the fitting assuring component from separating from the housing by engaging with the fitting assuring component.
