Since the detection member 4 includes the engagement arm 5 that engages with the engagement protrusion 3 a protruding from the side surface of the lock arm 3, the temporary engagement position always protrudes from the rear end surface of the female housing 2. Forward movement from is restricted. When the two housings 1 and 2 are properly fitted, the release arm 6 provided on the male housing 1 engages with the engagement arm 5 to disengage it from the engagement projection 3a, and the detection member 4 Is allowed to be pushed forward. Thus, the fitting state of the two housings 1 and 2 can be detected based on whether the detection member 4 can be moved or not. By the way, in order to suppress the rattling when the detecting member 4 moves, a pair of guide protrusions 7 are provided to protrude laterally from lower end portions of the left and right side surfaces of the detecting member 4. The guide projection 7 is fitted into a guide groove 9 provided on the side wall 8 of the female housing 2 and slides into the guide groove 9 when the detection member 4 is moved. It is designed to suppress rattling and guide smooth movement.

[0003]

In a state where the detection member 4 is assembled at the temporary locking position, it is exposed to the outside. Therefore, for example, when the female housing 2 is transported in a state where the detection member 4 is attached to the temporary locking position, the guide protrusion 7 is left exposed to the outside while protruding from the side surface of the detection member 4. For this reason, the connectors are likely to be damaged due to collision with other connectors during the transportation. The present invention has been completed based on the above circumstances, and has as its object to surely guide the moving operation of the detecting member.

[0004]

According to a first aspect of the present invention, there is provided a connector housing which can be fitted with a mating connector housing, the side surfaces of the connector housing intersecting with each other. A guide wall formed by bending so as to face the connector housing is connected, and between the guide wall and the connector housing, a detection member movable along the fitting direction of the two connector housings is assembled. One of the two connector housings is elastically displaced in a direction intersecting the fitting direction while the two connector housings are being fitted, and protrudes into the movement path of the detection member, An elastic displacement portion is provided, which elastically returns when the two connector housings are properly fitted and retracts from the movement path. The fitting state of the two connector housings can be detected based on whether or not the detecting member in the middle of the movement interferes with the elastic displacement portion, and a surface of the guide wall facing the connector housing. A guide portion is protruded, and the detecting member is sandwiched between the guide portion and an inner surface of the guide wall facing the guide portion, and the moving operation is guided. Has features.

According to a second aspect of the present invention, in the first aspect, the detecting member is moved on an inner surface of the guide wall facing the guide portion in a state where the two connector housings are properly fitted. When it reaches the final position, a restricting portion that can be engaged to restrict its movement is protruded inward, and an auxiliary member that can guide the moving operation with the detecting member interposed between the restricting portion and the guide portion. It is characterized in that the guide portion is formed continuously with the regulating portion.

According to a third aspect of the present invention, in the first or second aspect, the elastic displacement portion is provided with an elastic displacement portion as the two connector housings are properly fitted. It is characterized in that the lock arm is also used as a lock arm which can be locked to the mating side of the connector housing and hold the two connector housings in the fitted state.

[0007]

<Operation and effect of the invention><Invention of claim 1> When the detection member is sandwiched between the guide wall and the guide portion and slidably contacts, the detection member swings in a direction intersecting the movement direction when moving. The rattling is suppressed, and the movement of the detection member can be smoothly guided. Since the detection member itself is sandwiched and guided, the detection member does not need to protrude the guide protrusion sideways, and since the guide portion is arranged on the inner surface of the guide wall, It is possible to prevent the guide function from being impaired due to interference of foreign matter or the like.

<Invention of Claim 2> When the detecting member is moved after reaching the final position after the two connector housings are properly fitted, the movement is regulated by engaging with the regulating portion. Even if a gap is formed between the detection member and the inner surface of the guide wall due to the provision of the regulating portion on the inner surface of the guide wall facing the guide portion, the detection member is connected to the auxiliary guide portion and the guide continuous with the regulation portion. The wobble is prevented by being moved while being sandwiched between the parts.

<Invention of Claim 3> Since the elastic displacement portion also serves as the lock arm, the structure of the connector can be simplified.

The hood portion 21 of the second housing 20 is externally fitted to the first housing 10 in a state where 0 is kept at the temporary locking position. While the two housings 10 and 20 are being fitted together, the lock arm 23 has its front end connected to the inclined surface 1 of the lock projection 11.
It is elastically deformed upward while sliding on 1A (see FIG. 11). When the two housings 10 and 20 are fitted to the normal depth, the two terminal fittings 17 and 22 are electrically connected and the front end 23A of the lock arm 23 is connected to the lock projection 11.
, The lock arm 23 elastically returns, and as shown in FIG. 7, the front edge of the lock hole 24 of the lock arm 23 locks against the lock surface 11B of the lock protrusion 11 from behind, As a result, the two housings 10 and 20 are locked in the properly fitted state, and the disengagement is regulated. In addition, the front end 10F of the first housing 10 is
, The relative displacement of the housings 10 and 20 in the further fitting direction is restricted. The lock arm 23 that returns elastically does not interfere with the upper plate portion 33A of the detection member 30 that is waiting at the temporary locking position. Further, although the front end of the holding portion 25 of the second housing 20 and the holding arm 36 of the detection member 30 are close to each other, they do not contact each other.
There is no interference.

After the two housings 10 and 20 are properly fitted, the detection member 30 at the temporary locking position is moved forward (toward the final locking position).
When pushed into, the upper plate portion 33A does not pass above the lock arm 23 and the lock protrusion 11 and does not interfere with each other, and is allowed to be moved to the final locking position.

The upper plate portion 33A abuts on the front end portion 23A of the lock arm 23 before reaching the final locking position. At this time, the worker can feel that the two ends of the housing 10 and 20 are in a half-fitted state by feeling the end.

When the detection member 30 is further pushed forward (fully locked position side) from this state, the upper plate 33A of the detection member 30 pushes the lock arm 23 back, so that the second housing 20 is separated from the first housing 10. When the detection member 30 reaches the final locking position, the front end 23A of the lock arm 23 is returned to the front of the lock projection 11 as shown in FIG. At this time, the first terminal fitting 17 and the second terminal fitting 22 are separated from each other to be in a non-contact state. When the upper plate 33A of the detection member 30 abuts on the lock arm 23, the lower plate 33
B of the holding arm 36 also abuts against the tip of the holding portion 25 at the lower end of the second housing 20, and the detection member 30
Since the upper and lower housings are pressed against the housing 20 at two positions, no inclination occurs between the detection member 30 and the second housing 20. Note that the movement of the detection member 30 at this time also includes the guide wall 12 and the guide portions 40 and 4 as described above.
