## Abstract

A connector (10) includes a housing (20) and a connection detecting member (60) that is displaceable between a connection assurance position and a connection assurance release position. The connection detecting member (60) is mountable on the housing (20) and pushed from a pre-assembling position to the connection assurance release position. First arms (74) are on sides of the connection detecting member (60). Two first guide grooves (44) and two second guide grooves (48) are in the side walls (42) of the housing (20) and extend along a sliding direction of the connection detecting member. First claws (76) of the first arms (74) are in the first guide grooves (44) at the connection assurance position and the connection assurance release position, and are in the second guide grooves (48) at the pre-assembling position. The first arms (74) deflect by pushing the connection detecting member (60) to the connection assurance release position.

## Claims

### Claim 1

A connector, comprising:
a housing to be connected to a mating housing; and
a separate connection detecting member to be slidably mounted on the housing for connection assurance of the housing and the mating housing,
wherein:
the connection detecting member is relatively displaceable between a connection assurance position where connection assurance of the housing and the mating housing is made and a connection assurance release position where the connection assurance is released,
the connection detecting member is mountable on the housing by being pushed and displaced from a pre-assembling position before assembling is performed to the connection assurance release position in mounting the connection detecting member on the housing,
flexible arms are provided on both side parts of the connection detecting member,
the housing is provided with two side walls spaced apart in a direction intersecting a sliding direction of the connection detecting member and extending parallel to the sliding direction of the connection detecting member,
two first guide grooves along the sliding direction of the connection detecting member and two second guide grooves parallel to the first guide grooves and disposed above the first guide grooves are provided respectively in the side walls,
tip of the arms are in the first guide grooves at the connection assurance position and the connection assurance release position and the tip of the arms are in the second guide grooves at the pre-assembling position, and
the arms are deflected by pushing the connection detecting member, and the connection detecting member is displaced to the connection assurance release position when the connection detecting member is displaced from the pre-assembling position to the connection assurance release position.

### Claim 2 (depends on 1)

The connector of claim 1, wherein:
the housing is provided with a housing-side contact surface to be brought into contact with the connection detecting member at the connection assurance release position, and
the connection detecting member comes into contact with the housing-side contact surface to be positioned at the connection assurance release position when being displaced from the pre-assembling position to the connection assurance release position.
