The connector 1 according to this embodiment includes a housing 5 that can be fitted into a mating housing 3. It also includes a fitting detection member 7 that is movably assembled to the housing 5 and detects the fitting state of the mating housing 3 and the housing 5 by moving between a temporary locking position and a final locking position. ing.

Further, the moving direction in which the fitting detection member 7 is removed from the housing 5 is the same direction as the removal direction in which the housing 5 is removed from the mating housing 3. Further, a first retaining portion 9 is provided between the housing 5 and the fitting detection member 7 to restrict separation of the fitting detection member 7 from the housing 5.

And, between the housing 5 and the fitting detection member 7, when the fitting detection member 7 is moved in the direction of separating from the housing 5, the rotation of the fitting detection member 7 about the first retaining part 9 as a fulcrum is provided. A regulating section 11 is provided to regulate the.

Further, the restricting portion 11 is provided with a second retaining portion 13 that restricts detachment of the fitting detection member 7 from the housing 5.

Further, the fitting detection member 7 is provided with a detection lock arm 15 that can be elastically deformed and holds the fitting detection member 7 with respect to the housing 5 at a temporary locking position and a final locking position. The first retaining portion 9 is disposed within a range where the detection lock arm 15 is elastically deformed.

Further, the regulating portion 11 includes a convex portion 17 that protrudes from the fitting detection member 7 and a recess 19 that is provided on the housing 5 and engages with the convex portion 17 . Furthermore, the moving direction of the fitting detection member 7 is the same direction as the fitting direction and the separating direction between the mating housing 3 and the housing 5. The convex portion 17 and the concave portion 19 extend along the moving direction of the fitting detection member 7.

As shown in FIGS. 1 to 3, 9, 10, and 15 to 20, the mating housing 3 is made of an insulating material such as synthetic resin. The mating housing 3 is open on one side and is provided with a mating fitting portion 21 into which the housing 5 can fit. A plurality of through holes are formed in the bottom of the mating fitting part 21, and for example, a plurality of mating terminals (not shown) electrically connected to the circuit board are fixed into the through holes by press fitting, etc. A mating terminal is arranged within the mating fitting part 21.

On the opening side of such a mating fitting part 21, a locked part 23 that maintains the fitted state of the mating housing 3 and the housing 5 when the mating housing 3 and the housing 5 are fitted is directed inward. A plurality of (in this case, two) protrusions are provided. In such a mating housing 3, when the mating fitting portion 21 fits into the housing 5, the mating terminal and a terminal (not shown) accommodated in the housing 5 are electrically connected.

As shown in FIGS. 1, 4, 5, and 9 to 22, the housing 5 is made of an insulating material such as synthetic resin. The housing 5 includes a fitting part 25, a lock arm 27, and a detection housing part 29.

The fitting part 25 is formed into a housing shape so that it can be accommodated inside the mating fitting part 21 of the mating housing 3 . Inside this fitting portion 25, terminal accommodating chambers 31 extending along the fitting direction are arranged in multiple rows along the width direction of the housing 5, and in multiple stages along the height direction of the housing 5. It is located. The plurality of terminal storage chambers 31 each accommodate a plurality of terminals (not shown) electrically connected to, for example, a power source, a device, or the like.

A locking lance 33 is provided within the terminal accommodating chamber 31 so as to be elastically deformable. The locking lance 33 prevents the terminal from coming out of the terminal accommodating chamber 31 by engaging with the terminal accommodated in the terminal accommodating chamber 31 . Further, a retainer 35 is disposed in a through hole that communicates the plurality of terminal accommodating chambers 31 with each other. The retainer 35 engages with the terminal accommodated in the terminal accommodation chamber 31, thereby doubly preventing the terminal from coming out from the terminal accommodation chamber 31.

When such a fitting portion 25 is fitted into the mating fitting portion 21 of the mating housing 3, the terminal and the mating terminal are electrically connected. A lock arm 27 is provided on the upper surface of this fitting portion 25 .

The lock arms 27 extend along the length direction of the housing 5, that is, the fitting direction and the disengaging direction, and a plurality of lock arms 27 (four in this case) are arranged along the width direction of the housing 5. Each of the plurality of lock arms 27 has one end on the front side in the fitting direction as a base end formed of a single member continuous with the fitting part 25, and the other end side on the rear side in the fitting direction in the height direction of the housing 5. The free end is arranged to be elastically deformable. The plurality of lock arms 27 are formed of a single member continuous with the interlocking portion 37 extending along the width direction of the housing 5, and the elastic deformation of the plurality of lock arms 27 is interlocked.

In the vicinity of the center of the two lock arms 27 located on the center side among the plurality of lock arms 27, a lock part 39 that can be engaged with the locked part 23 of the mating fitting part 21 is provided on the outside in the width direction of the housing 5. It is projected towards. Furthermore, a housing rib 41 is provided in a portion of the lock portion 39 adjacent to the outside in the width direction of the housing 5 so as to protrude toward the outside in the width direction of the housing 5 . Furthermore, bosses 43 are provided on the free end sides of the two outer lock arms 27 among the plurality of lock arms 27, respectively, so as to protrude outward in the width direction of the housing 5.

In such a plurality of lock arms 27, when the fitting part 25 is inserted into the mating fitting part 21, the locking part 39 and the locked part 23 come into contact, and the locking part 39 gets over the locked part 23. It slides like this. Due to this sliding movement between the locking portion 39 and the locked portion 23, the plurality of locking arms 27 are elastically deformed downward in the housing 5 via the interlocking portion 37.

Then, when the fitting part 25 is housed in the proper position within the mating fitting part 21, the locking part 39 gets over the locked part 23. At this time, the plurality of lock arms 27 are restored upwardly of the housing 5 via the interlocking part 37, and the locking part 39 and the locked part 23 are engaged in the detachment direction. The engagement between the lock portion 39 and the locked portion 23 maintains the fitted state between the mating housing 3 and the housing 5.

The detection housing section 29 includes side walls 45, 45 that are erected upward from the upper surface of the fitting section 25 as a single piece continuous with the fitting section 25, and side walls 45, 45 on the upper end side of the side walls 45, 45. It consists of side walls 45, 45 and a connecting wall 47 formed of one continuous member so as to be connected. The detection accommodating portion 29 accommodates the fitting detection member 7 so as to be movable in the fitting direction and the detachment direction, which are the length directions of the housing 5 .

As shown in FIGS. 1, 6 to 22, the fitting detection member 7 is made of an insulating material such as synthetic resin. This fitting detection member 7 includes a main body 49 and a detection lock arm 15.

The main body 49 has side parts 51, 51 extending in the height direction of the housing 5, and is continuous with the side parts 51, 51 so as to connect the side parts 51, 51 to the upper end sides of the side parts 51, 51. It consists of an operating section 53 formed of a single member. This main body 49 is arranged in the detection housing part 29 such that the side parts 51, 51 can be housed in the detection housing part 29, and the operating part 53 is exposed from the detection housing part 29. Such a main body 49 can be moved in the fitting direction and the detaching direction of the housing 5 by pressing the operating part 53.

An inclined portion 55 that slopes from the bottom to the top in the direction of separation from the housing 5 is provided on the end face of the side portions 51, 51 of the main body 49 in the direction of separation from the housing 5. The inclined portion 55 is arranged to face the boss 43 of the lock arm 27 in a state where the fitting detection member 7 is held in the temporary locking position (see FIG. 10) with respect to the housing 5.

Such an inclined portion 55 slides on the boss 43 when the fitting detection member 7 is moved in the direction of separation from the housing 5 from the temporary locking position. Due to the sliding movement between the inclined portion 55 and the boss 43, the plurality of lock arms 27 are elastically deformed downward via the interlocking portion 37.

Due to this elastic deformation of the lock arm 27, the engagement between the locked portion 23 and the lock portion 39 is released, and the fitting between the mating housing 3 and the housing 5 can be released. By providing the inclined portion 55 on the fit detection member 7 in this manner, the lock arm 27 can be elastically deformed by movement of the fit detection member 7.

Therefore, there is no need to perform an operation to elastically deform the lock arm 27 directly, and the workability of disengaging the mating housing 3 and the housing 5 from each other can be improved. Note that the lock arm 27 is provided with a pressing portion 57 (see FIG. 4) that can directly elastically deform the lock arm 27. The detection lock arm 15 is provided in such a main body 49 as a continuous, elastically deformable member.

The detection lock arms 15 extend along the moving direction of the fitting detection member 7, and a plurality of detection lock arms 15 (two in this case) are arranged along the width direction of the fitting detection member 7. Each of the plurality of detection lock arms 15 has one end on the detachment direction side as a base end formed of a single member continuous with the operating section 53 of the main body 49, and the other end side on the fitting direction side as the fitting detection member 7. The free end is arranged to be elastically deformable in the height direction.

A locking portion 59 that can be engaged with the locking portion 39 of the locking arm 27 is provided at the free end of the detection locking arm 15 . This locking portion 59 is engaged with the locking portion 39 of the lock arm 27 in the detachment direction ( (See Figure 11). Due to the engagement between the locking portion 59 and the locking portion 39, the fitting detection member 7 does not move in the fitting direction of the housing 5, and the fitting detection member 7 can be held at the temporary locking position. .

The engagement between the locking portion 59 and the disengagement direction side of the locking portion 39 is achieved by pressing the operating portion 53 in the fitting direction, with the housing 5 held in the temporary locking position. It is set so that it can be fitted into the mating housing 3.

Here, at the free end of the detection lock arm 15, a locking protrusion 61 and a detection rib 63 are provided at a portion adjacent to the locking portion 59 on the outside in the width direction of the fitting detection member 7.

The locking protrusion 61 is arranged to face the housing rib 41 of the lock arm 27 in the fitting direction (see FIG. 12) when the fitting detection member 7 is placed in the temporary locking position (see FIG. 10). ). This locking protrusion 61 comes into contact with the housing rib 41 when the fitting detection member 7 is about to move in the fitting direction at the temporary locking position of the fitting detection member 7 . The contact between the locking protrusion 61 and the housing rib 41 can prevent the fitting detection member 7 from moving in the fitting direction from the temporary locking position.

The detection rib 63 is disposed facing upwardly in the direction of elastic deformation of the housing rib 41 of the lock arm 27 and the detection lock arm 15 when the fitting detection member 7 is disposed at the temporary locking position (Fig. 12). The detection rib 63 comes into contact with the housing rib 41 when the detection lock arm 15 attempts to elastically deform upward in the temporary locking position of the fitting detection member 7 .

Due to the contact between the detection rib 63 and the housing rib 41, the detection lock arm 15 is prevented from being elastically deformed upward. The engagement with the rib 41 can be maintained. Therefore, the fitting detection member 7 can be stably held in the temporary locking position.

The locking portion 59 adjacent to the locking protrusion 61 and the detection rib 63 is designed to prevent the locking portion 39 from riding on the locked portion 23 while the mating housing 3 and the housing 5 are being fitted together (see FIG. 15). Sometimes, it slides on the locked part 23. The sliding movement between the locking portion 59 and the locked portion 23 causes the detection lock arm 15 to be elastically deformed downward. At this time, the locking portion 59 engages with the locking portion 39 in the detachment direction, and maintains the temporary locking position of the fitting detection member 7 with respect to the housing 5.

Such a locking part 59 is capable of getting over the locking part 39 when the mating housing 3 and the housing 5 are fitted together and the locking part 39 is engaged with the locked part 23 (see FIG. 16). becomes. Therefore, by moving the fitting detection member 7 from the temporary locking position in the fitting direction, the locking part 59 slides on the locking part 39, and the detection lock arm 15 is elastically deformed downward.

When the fitting detection member 7 is placed in the final locking position with respect to the housing 5 (see FIG. 17), the detection lock arm 15 is restored upward, and the locking portion 59 is moved in the fitting direction of the locking portion 39. engaged on the side. This engagement between the locking portion 59 and the locking portion 39 prevents the fitting detection member 7 from moving in the direction in which the housing 5 is removed, and the fitting detection member 7 can be held at the final locking position. Note that the engagement between the locking portion 59 and the locking portion 39 at the main locking position can be released by moving the fitting detection member 7 in the disengagement direction.

Here, the operating portion 53 of the fitting detection member 7 is provided with a stepped portion 65 on the fitting direction side. This stepped portion 65 faces the interlocking portion 37 of the lock arm 27 and the lower side in the direction of elastic deformation of the lock arm 27 when the fitting detection member 7 is placed in the final locking position (see FIG. 17). Placed. Such a stepped portion 65 comes into contact with the interlocking portion 37 when the lock arm 27 attempts to elastically deform downward in the final locking position of the fitting detection member 7 .

Due to the contact between the stepped portion 65 and the interlocking portion 37, the lock arm 27 is not elastically deformed downward, and the engagement between the locked portion 23 and the lock portion 39 is not released. Therefore, in the final locking position of the fitting detection member 7, the fitted state between the mating housing 3 and the housing 5 can be stably maintained.

If the mating housing 3 and the housing 5 are not completely fitted, the fitting detection member 7 will be in a temporary locking position (see FIG. 10) due to the engagement between the locking part 59 and the locking part 39. It is not possible to move from the main locking position to the final locking position (see FIG. 17).

Therefore, if the fitting detection member 7 can be moved from the temporary locking position to the final locking position, it is difficult to detect that the mating housing 3 and the housing 5 are properly fitted. can. On the other hand, if the fitting detection member 7 cannot be moved from the temporary locking position to the final locking position, it is possible to detect that the mating housing 3 and the housing 5 are not properly fitted. .

Such a fitting detection member 7 can release the fitting between the mating housing 3 and the housing 5 by moving it in the disengagement direction from the main locking position (see FIG. 17). In order to release the mating between the mating housing 3 and the housing 5, the operating portion 53 of the fitting detection member 7 is pressed in the detachment direction to move the fitting detection member 7 in the detachment direction.

By this movement of the fitting detection member 7 in the detachment direction, the locking part 59 slides on the locking part 39, the detection lock arm 15 is elastically deformed downward, and the fitting detection member 7 is moved to the main locking position. 19 to the temporary locking position (see FIG. 19). When the fit detection member 7 moves in the detachment direction beyond the temporary locking position, the boss 43 of the lock arm 27 and the inclined portion 55 of the fit detection member 7 slide (see FIG. 20).

This sliding movement between the boss 43 and the inclined portion 55 causes the lock arm 27 to be elastically deformed downward, and the engagement between the locked portion 23 and the lock portion 39 is released. Then, by further moving the fitting detection member 7 in the detachment direction, the housing 5 can be detached from the mating housing 3. At this time, separation of the fitting detection member 7 from the housing 5 is prevented by a first retaining portion 9 provided between the housing 5 and the fitting detection member 7.

The first retaining portion 9 is provided between the housing 5 and the fitting detection member 7, and includes a housing first protrusion 67 and a first detection protrusion 69.

The first housing protrusion 67 is a member that protrudes upward from the upper surface of the fitting part 25 of the housing 5 and is continuous with the fitting part 25, and corresponds to a plurality of (here, two) detection lock arms 15. A plurality of them (two in this case) are placed at each location.

The first detection protrusion 69 is a member that protrudes downward from the lower surface of a plurality of (here, two) detection lock arms 15 of the fitting detection member 7 and is continuous with the detection lock arms 15 . This first detection protrusion 69 is spaced apart from the housing first protrusion 67 with respect to the moving direction of the fit detection member 7 when the fit detection member 7 is placed in the temporary locking position (see FIG. 10). (See Figure 13).

When the fitting detection member 7 moves in the detachment direction with the locked portion 23 and the locking portion 39 disengaged, the first retaining portion 9 is detected to be connected to the housing first protrusion 67. The first protrusion 69 is engaged. This engagement between the housing first protrusion 67 and the first detection protrusion 69 prevents the fitting detection member 7 from separating from the housing 5. Therefore, by pressing the operating portion 53 of the fitting detection member 7 in the detachment direction, the housing 5 can be detached from the mating housing 3.

The first retaining portion 9 is set such that the protrusion heights of the first housing protrusion 67 and the first detection protrusion 69 are located within a range in which the detection lock arm 15 is elastically deformed. By setting the first retaining portion 9 in this manner, it is possible to arrange the first retaining portion 9 within the space where the detection lock arm 15 undergoes elastic deformation, and it is possible to suppress the connector 1 from increasing in size.

Here, in the detection lock arm 15, when the fitting detection member 7 moves in the detachment direction and the first retaining part 9 engages, the locking part 59 slides with the interlocking part 37 of the lock arm 27, and the locking part 59 slides downward. It is elastically deformed towards the side. A first detection protrusion 69 is provided protruding from the lower side of the detection lock arm 15 in the direction of elastic deformation.

When the first detection protrusion 69 engages with the first housing protrusion 67, the engagement distance with the first housing protrusion 67 is increased due to the downward elastic deformation of the detection lock arm 15. Therefore, the resistance against movement of the fitting detection member 7 in the detachment direction can be increased, and the fitting detection member 7 can be stably held in the housing 5.

Such a first retaining portion 9 serves as a fulcrum when the housing 5 is separated from the mating housing 3 by moving the fitting detecting member 7 in the detaching direction, and the fitting detecting member 7 rotates. It may be inclined to do so. When the mating detection member 7 is tilted, the operating force that presses the operating portion 53 in the detachment direction is dispersed in the rotational direction, and sufficient operating force is not transmitted in the detachment direction, resulting in a decrease in detachment workability. Put it away.

Therefore, a regulating portion 11 is provided between the housing 5 and the fitting detecting member 7 to restrict rotation of the fitting detecting member 7 using the first retaining portion 9 as a fulcrum. The regulating portion 11 includes a convex portion 17 and a concave portion 19.

The convex portion 17 is a member that is continuous with the side portions 51 , 51 and protrudes outward from the outer surface of the side portions 51 , 51 of the fit detection member 7 in the width direction of the fit detection member 7 . This convex portion 17 extends along the moving direction of the fitting detection member 7.

The recess 19 extends inside the side walls 45 , 45 of the detection accommodating portion 29 of the housing 5 so as to be able to engage with the protrusion 17 along the moving direction of the fitting detection member 7 . The recess 19 has an open end face in the removal direction of the housing 5, and is provided so as to be able to engage with the protrusion 17 at least up to the final locking position of the fitting detection member 7. Such a recess 19 is engaged with the protrusion 17 when the fitting detection member 7 is disposed in the housing 5.

Such a restricting portion 11 is configured such that when the operating portion 53 of the fitting detection member 7 is pressed in the detachment direction while the first retaining portion 9 is engaged, the convex portion 17 and the concave portion 19 engage with each other. , restricts rotation of the fitting detection member 7 about the first retaining portion 9 as a fulcrum. Therefore, the fitting detection member 7 is not tilted, and the operating force in the detachment direction is not dispersed in the rotation direction. Therefore, the operating force that presses the operating portion 53 of the fitting detection member 7 is transmitted to the housing 5 in the detachment direction via the first retaining portion 9. Therefore, the housing 5 can be stably separated from the mating housing 3 via the fitting detection member 7.

Further, since the convex portion 17 and the recessed portion 19 extend in the moving direction of the fitting detection member 7, the fitting detection member 7 does not rotate relative to the housing 5 when the fitting detection member 7 moves. There is no. Therefore, the operating force for pressing the operating portion 53 of the fitting detection member 7 is not dispersed in the rotational direction, and the fitting detection member 7 can be stably operated in the moving direction.

The restriction portion 11 is provided with a second retaining portion 13 that restricts the fitting detection member 7 from coming off from the housing 5 . The second retaining portion 13 includes a second housing protrusion 71 and a second detection protrusion 73.

The second housing protrusion 71 is a single member that is continuous with the recess 19 and protrudes outward from the bottom of each of the plurality of (two in this case) recesses 19 in the removal direction.

The second detection protrusion 73 is a member that protrudes from the outer surface of each of the plurality of (two in this case) protrusions 17 in the fitting direction toward the outside in the width direction of the fitting detection member 7 and continues with the protrusion 17. It is set up. This second detection protrusion 73 is spaced apart from the housing second protrusion 71 with respect to the moving direction of the fit detection member 7 when the fit detection member 7 is placed in the temporary locking position (see FIG. 10). (See Figure 14).

Such a second retaining portion 13 is detected by the housing second protrusion 71 when the fitting detection member 7 moves in the detachment direction with the locked portion 23 and the locking portion 39 disengaged. The second protrusion 73 is engaged (see FIGS. 21 and 22). Due to this engagement between the second housing protrusion 71 and the second detection protrusion 73, the fitting detection member 7 does not come off from the housing 5. Therefore, by pressing the operating portion 53 of the fitting detection member 7 in the detachment direction, the housing 5 can be detached from the mating housing 3.

In such a connector 1, when the fitting detection member 7 is moved in the direction of separating from the housing 5, a fitting detection is performed between the housing 5 and the fitting detection member 7 using the first retaining portion 9 as a fulcrum. A regulating portion 11 that regulates rotation of the member 7 is provided.

Therefore, when an operating force is applied to the mating detection member 7 in the disengagement direction, the mating detection member 7 does not tilt in the rotational direction using the first retaining portion 9 as a fulcrum, and the operating force for uncoupling is reduced. It is not dispersed in the direction of rotation.

Therefore, in such a connector 1, the operating force applied to the mating detection member 7 for uncoupling the mating housing 3 and the housing 5 can be sufficiently transmitted to the housing 5 in the detachment direction, and the detachment workability is improved. can be improved.

Further, the restricting portion 11 is provided with a second retaining portion 13 that restricts detachment of the fitting detection member 7 from the housing 5. Therefore, the fitting detection member 7 does not separate from the housing 5, and the housing 5 can be stably separated from the mating housing 3 via the fitting detection member 7.

Further, the fitting detection member 7 is provided with a detection lock arm 15 that can be elastically deformed and holds the fitting detection member 7 with respect to the housing 5 at a temporary locking position and a final locking position. The first retaining portion 9 is disposed within a range where the detection lock arm 15 is elastically deformed.

Therefore, the first retaining portion 9 can be disposed within the space where the detection lock arm 15 undergoes elastic deformation, and it is possible to suppress the connector 1 from increasing in size.

Further, the regulating portion 11 includes a convex portion 17 that protrudes from the fitting detection member 7 and a recess 19 that is provided on the housing 5 and engages with the convex portion 17 . Furthermore, the moving direction of the fitting detection member 7 is the same direction as the fitting direction and the separating direction between the mating housing 3 and the housing 5. The convex portion 17 and the concave portion 19 extend along the moving direction of the fitting detection member 7.

Therefore, when the fitting detection member 7 moves, the fitting detection member 7 does not rotate relative to the housing 5. Therefore, the operating force for operating the fit detection member 7 in the movement direction is not dispersed in the rotation direction, and the fit detection member 7 can be stably operated in the movement direction.

Although this embodiment has been described above, this embodiment is not limited to these, and various modifications can be made within the scope of the gist of this embodiment.

For example, although the housing is provided with four lock arms, the present invention is not limited to this, and the number of lock arms may be one, or two or more. Moreover, although two detection lock arms are provided on the fitting detection member, the number of detection lock arms is not limited to this, and the number of detection lock arms may be one, or three or more.

Furthermore, the direction of movement of the mating detection member between the temporary locking position and the final locking position is the same direction as the mating direction and disengagement direction between the mating housing and the housing, but this is not limiting. do not have.

For example, the direction of movement of the fitting detection member between the temporary locking position and the final locking position may be perpendicular to the fitting and disengaging directions of the mating housing and the housing. However, the moving direction in which the fitting detection member is removed from the housing is the same as the removal direction in which the housing is removed from the mating housing.

Further, in the regulating portion, the convex portion is provided on the fitting detection member and the recessed portion is provided on the housing, but the protrusion may be provided on the housing and the recessed portion may be provided on the fitting detection member.
