Description

  The present invention relates to a connector.

Patent Document 1 discloses a connector including a detection member for detecting whether or not a first housing and a second housing are properly fitted. The detection member is attached to the first housing, and can slide in the front-rear direction between the standby position and the detection position. In the half-fitted state where both housings do not reach the normal fitting, the detection member is restricted from moving from the standby position to the detection position, and when both housings reach the normal fitting state, the detection member is detected from the standby position. Allowed to move to position. Thereby, the fitting state of both housings is detected based on whether or not the detection member can move to the detection position.
JP 2006-253073 A

  In the conventional connector, regardless of whether the detection member is in the standby position or the detection position, the entire detection member is exposed on the outer surface of the first housing, and the detection member is always visually confirmed. Be able to. Therefore, it seems that it is easy to determine the position of the detection member at first glance, but the shape and size of the detection member do not seem to change regardless of whether the detection member is in the standby position or the detection position. It is difficult to instantaneously determine the position of the detection member.

  As a countermeasure against this, a structure in which a cover portion for covering a part of the detection member in the first housing is provided can be considered. According to this structure, the apparent shape and size of the detection member change depending on whether the detection member is at the standby position or the detection position, so that it is expected that the detection member position can be easily determined. .

However, when the connector is downsized, the movement distance of the detection member is reduced accordingly, so that the apparent change in the shape and size of the detection member is slight. Since it is difficult to visually confirm the presence or absence of such a slight change, it can be said that the position of the detection member is still difficult to determine.
The present invention has been completed based on the above circumstances, and an object thereof is to reliably determine that a detection member has reached a detection position.

  As means for achieving the above object, the invention of claim 1 is characterized in that a first housing, a second housing that can be fitted to the first housing, a standby position provided in the first housing, Movement between the detection position ahead of the standby position is possible, and the detection member moves from the standby position to the detection position in the middle of the fitting of the first housing and the second housing. In a connector in which the detection member is allowed to move from the standby position to the detection position when the movement of the first housing and the second housing reaches a proper fitting state. The outer surface of the first housing exposes at least the rear end of the detection member when the detection member is at the standby position, and the detection member is at the detection position. A cover portion that covers at least a part of the detection member is formed, and the cover portion is exposed on an outer surface of the cover portion and can be elastically bent in a direction intersecting a moving direction of the detection member. A flexible detection unit is formed, and the detection member is elastically bent by bringing the flexible detection unit into contact with the detection member in a process in which the detection member moves from the standby position toward the detection position. Is characterized in that an interference part is formed for elastically returning the flexible detection part as it reaches the detection position.

  According to a second aspect of the present invention, the rear end of the detection member is the same as the rear end of the covering portion in the front-rear direction or the rear end when the detection member is in the detection position. It is characterized in that it is arranged at a position ahead of the rear end of the cover.

  According to a third aspect of the present invention, in the one according to the second aspect, the formation region of the cover portion in the width direction is a range that covers the entire width of the detection member. It is characterized in that a notch is formed to expose a part of the detection member in the cover in a state where the detection member is at the detection position.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the cutout portion has a slit-like shape that is cut forward from the rear end of the cover portion, and is paired with an interval in the width direction. It is characterized by the fact that the portion between the pair of cutout portions is the flexible detection portion.

  According to a fifth aspect of the present invention, in the apparatus according to any one of the first to fourth aspects, in the state where the detection member moves to the detection position and the flexible detection section is elastically restored, the interference section is It is characterized in that the movement of the detection member toward the standby position is restricted by locking the flexible detection unit from the front.

It has a feature in that an operation unit that enables the operation is provided.

<Invention of Claim 1>
Whether the detection member is in the standby position or the detection position can be determined based on the longitudinal length of the portion of the detection member exposed from the rear end of the cover. Furthermore, in the process in which the detection member moves forward from the standby position and reaches the detection position, it is possible to visually confirm the operation in which the flexible detection unit elastically returns after being elastically bent once. It is possible to reliably determine that the position has been reached.

<Invention of Claim 2>
In the state where the detection member is in the standby position, at least the rear end portion of the detection member is exposed from the cover portion, but when the detection member moves to the detection position, the rear end portion of the detection member sinks into the cover portion. Since the state is not exposed, the position of the detection member can be determined based on whether or not the rear end of the detection member can be viewed.

<Invention of Claim 3>
In a state where the detection member has moved to the detection position and has entered the cover portion, a part of the detection member can be visually confirmed from the outside of the cover portion through the cutout portion, so that the detection member is not attached to the first housing. Identification can be made.

<Invention of Claim 4>
Since the slit for forming the flexible detecting portion also has a function as a notched portion, the shape of the cover portion is compared with the case where the notched portion is formed separately from the slit for forming the flexible detecting portion. Can be simplified.

<Invention of Claim 5>
Since the flexible detection unit and the interference unit also have a lock function for restricting the movement of the detection member to the standby position side, the shape of the first housing or the detection member is smaller than when a dedicated lock unit is provided. Simplification can be achieved.

<Invention of Claim 6>
Since the operation unit is arranged behind the interference unit, there is no possibility that the interference unit or the flexible detection unit may hinder the operation when a pressing operation is performed on the operation unit from the rear.

A second notch 20 is formed. Both the first cutout 19 and the second cutout 20 are penetrated from the upper surface (outer surface) to the lower surface (inner surface facing the accommodation space 15) of the cover portion 13. The dimensions of the first notch portion 19 and the second notch portion 20 in the front-rear direction are substantially the same as each other, and are approximately 1/3 of the total length of the cover portion 13.

  A region elongated in the front-rear direction between the first notch 19 and the second notch 20 in the cover 13 extends in a cantilevered manner in the back-and-forth direction (the moving direction of the detection member 30). It is the flexible detection part 21 which can be elastically bent to the direction which cross | intersects. The flexible detector 21 is parallel to the moving direction of the detection member 30 in a free state where the flexible detector 21 is not elastically bent. On the lower surface (surface facing the accommodation space 15) of the flexure detection unit 21, a locking projection 22 that protrudes downward from its rear end is formed.

  Moreover, the area | region between a pair of 2nd notch parts 20 of the cover part 13 becomes the collar part 23 of the form extended to the back in the cantilever shape while forming a substantially square shape. The thickness dimension (vertical dimension) of the flange portion 23 is a dimension that combines the plate thickness dimension of the flexure detection section 21 and the protruding dimension of the locking projection 22 and has high rigidity that hardly causes elastic deformation. is doing. In addition, the rear end edge of the flange portion 23 is arranged so as to be flush with the rear end edge of the flexibility detection unit 21.

  A detection member 30 is attached to the first housing 10. The detection member 30 is made of synthetic resin, and has a plate-like main body portion 31 that forms a horizontally-oriented square as a whole, and a pair of left and right symmetrical leg portions 32 formed at the rear end portion of the plate-like main body portion 31. . The leg portion 32 extends downward from the left and right side edges of the plate-like main body portion 31 and has a substantially L shape with its extended end portion (lower end portion) bent inward at a substantially right angle. Yes.

  The detection member 30 slides the plate-shaped main body 31 on the upper surface of the guide protrusion 16 and slides the pair of leg portions 32 on the left and right side surfaces of the guide protrusion 16 to thereby set the standby position (FIG. 2). 4) and a detection position in front of the standby position (see FIGS. 1 and 6), moving in the front-rear direction (a direction parallel to the fitting / removing direction of the housings 10 and 50). (Slide) can be. In a range of movement between the standby position and the detection position of the detection member 30, a state in which at least the front end portion of the detection member 30 is accommodated in the accommodation space 15 and has entered under the cover portion 13 (inside). It becomes.

  The plate-like main body portion 31 is formed with a pair of slit portions that are notched rearward from the front edge thereof, and a portion between the pair of slit portions of the plate-like main body portion 31 is a flexible arm portion 33. Yes. The flexible arm portion 33 can be elastically bent in the vertical direction, and a restriction projection 34 is formed on the front end portion of the flexible arm portion 33 so as to protrude from the lower surface (the surface opposite to the upper surface of the lock arm 17). Yes.

  In the plate-like main body portion 31, an operation portion 35 is formed continuously extending over the entire width of the plate-like main body portion 31 so as to protrude upward in a rib shape along the rear edge. Similarly, the plate-like main body 31 is formed with a pair of left and right symmetrical side walls 36 that protrude upward in a rib shape along both left and right side edges. The formation region of the side wall 36 in the front-rear direction is a range from the substantially center position in the front-rear direction of the plate-like main body 31 to the rear end of the plate-like main body 31, and the rear end of the side wall 36 is the operation part 35. It is connected to the left and right ends. Further, the side wall 36 and the operation unit 35 have the same height dimension.

  A pair of left and right symmetric interference portions 37 are formed on the upper surface of the plate-shaped main body 31 (the surface facing the cover portion 13). The interference portion 37 has a shape protruding inward in the width direction from the inner surface of the side wall 36, and has a protrusion shape protruding in a dome shape from the upper surface of the plate-like main body portion 31 when viewed from the side. The formation position of the interference portion 37 in the front-rear direction is slightly behind the center position of the side wall 36 in the front-rear direction. A recessed portion between the interference portion 37 and the operation portion 35 on the upper surface of the plate-shaped main body portion 31 is a pair of left and right symmetrical locking recesses 38.

  In addition, a pair of left and right symmetrical retaining protrusions 39 are formed on the upper surface of the plate-like main body 31. Similar to the interference portion 37, the retaining projection 39 has a shape that protrudes inward in the width direction from the inner surface of the side wall 36, and has a protrusion shape that protrudes in a dome shape from the upper surface of the plate-like main body portion 31 when viewed from the side. There is no. The formation position of the retaining protrusion 39 in the front-rear direction is ahead of the interference part 37 and corresponds to the front end part of the side wall 36. Further, the recessed portion between the retaining protrusion 39 and the interference portion 37 is a relief recess 40.

  The width dimension of the interference part 37 and the retaining protrusion 39 is substantially the same as the width dimension of the flexible detecting part 21, and the interference part 37 and the retaining protrusion 39 in the state where the detection member 30 is attached to the first housing 10. Are arranged so as to correspond to the flexibility detector 21. Further, the projecting dimension of the interference part 37 from the plate-like main body part 31 and the projecting dimension of the retaining protrusion 39 from the plate-like main body part 31 are the same dimensions, and the height dimension of the side wall 36 and the operation part 35 is the same. Same dimensions.

  As shown in FIGS. 4 to 6, the formation region of the cover portion 13 in the width direction (that is, the distance between the inner surfaces of the left and right side walls 14 and the width dimension of the housing space 15 and the cover portion 13) is detected. The dimension is slightly larger than the width dimension of the member 30 (a dimension corresponding to a clearance for allowing movement of the detection member 30 in the accommodation space 15). In other words, the formation region of the cover portion 13 is a range that covers the detection member 30 over its entire width.

  When both the housings 10 and 50 are detached and the detection member 30 is in the standby position, the rear end portion of the detection member 30 is positioned behind the rear end edge of the cover portion 13 as shown in FIGS. The state in which the rear end portion of the detection member 30 is exposed to the outside in the region behind the cover portion 13, that is, the state in which the detection member 30 is visible from above. In other words, in the detection member 30, the interference portion 37, the locking recess 38, and the operation portion 35 are exposed behind the cover portion 13, and a region in front of the interference portion 37 is below the cover portion 13 (in the accommodation space 15. ).

  Further, in the state where the detection member 30 is in the standby position, although not shown in the figure, the restriction projection 34 of the flexible arm portion 33 is engaged with the front end edge of the lock hole 18 of the lock arm 17 from behind, The forward relative movement of the detection member 30 with respect to the first housing 10 is restricted. Further, as shown in FIG. 2, when the retaining protrusion 39 is locked from the front with respect to the locking protrusion 22 of the cover portion 13, the relative movement of the detection member 30 to the rear with respect to the first housing 10 is restricted. The That is, the detection member 30 is locked so as not to move in the front-rear direction at the standby position.

  When both the housings 10 and 50 are detached and the detection member 30 is in the detection position, the locking protrusion 22 is fitted into the locking recess 38 as shown in FIG. The forward and backward relative movement with respect to the housing 10 is restricted, and the housing 10 is locked so as not to move at the detection position. Further, the restricting projection 34 of the flexible arm portion 33 is positioned in front of the lock arm 17, and as shown in FIGS. 1 and 6, the rear end edge (rear surface of the operation portion 35) of the detection member 30 is in the front-rear direction. , At the same position as the rear edge of the cover 13 (flexibility detector 21 and collar 23). That is, the entire region extending from the front end to the rear end of the detection member 30 in the front-rear direction is in a state of being submerged below the cover portion 13 (in the accommodation space 15).

  The second housing 50 is made of synthetic resin, and is integrally formed with a terminal holding portion 51 and a hood portion 52 that protrudes from the terminal holding portion 51 to the front of the second housing 50 (rightward in FIGS. 1 to 3). The terminal holding portion 51 holds a male terminal fitting 53 and the front end portion thereof is surrounded by the hood portion 52. The upper surface plate constituting the hood portion 52 is formed with a lock projection 54 that protrudes from the upper surface (outer surface).

  When the first housing 10 and the second housing 50 are fitted, the hood portion 52 is placed in the space between the terminal fitting portion 11 and the cylindrical fitting portion 12 with the detection member 30 held at the standby position. To enter. In the fitting process, the lock arm 17 is elastically bent upward by the front end of the lock arm 17 riding on the lock protrusion 54. Since the front end portion of the flexible arm portion 33 of the detection member 30 is in contact with the upper surface of the lock arm 17, the flexible arm portion 33 is also elastically bent upward as the lock arm 17 is elastically bent upward. Be made. However, since the area | region except the flexible arm part 33 in the plate-shaped main-body part 31 is fitted by the guide protrusion 16, it does not displace.

  When the fitting of both the housings 10 and 50 proceeds, a part of the lock protrusion 54 is in a state corresponding to the lock hole 18, and a part of the lock protrusion 54 is locked in the lock hole 18. Under the control projection 34 of 33, it sinks. This state is maintained until both housings 10 and 50 reach a normal fitting state.

  When the housings 10 and 50 are brought into the proper fitting state, the entire lock projection 54 corresponds to the lock hole 18, so that the lock arm 17 is elastically returned downward, and the front edge of the lock hole 18. Is locked to the lock protrusion 54. By this locking action, both the housings 10 and 50 are locked in a state in which separation is restricted. At this time, as shown in FIG. 2, since the restricting protrusion 34 remains on the lock protrusion 54, the flexible arm portion 33 is kept elastically bent upward.

  In this way, when the housings 10 and 50 are properly fitted and the lock arm 17 is elastically restored, the upper surface of the lock arm 17 and the upper surface of the lock protrusion 54 are arranged so as to be lined up and down at substantially the same height. Is done. As a result, the engagement between the restricting protrusion 34 and the lock hole 18 is released, so that the detection member 30 at the standby position is allowed to move to the detection position (forward).

  Thereafter, the rear surface of the operation unit 35 is pushed with a finger to move the detection member 30 to the front detection position. At this time, the restricting protrusion 34 of the flexibility detecting portion 21 slides forward on the upper surface of the lock protrusion 54, then moves onto the upper surface of the front end portion of the lock arm 17, and slides the upper surface of the front end portion of the lock arm 17 forward. Move. Further, immediately after the movement of the detection member 30 is started, the locking protrusion 22 of the flexible detector 21 is released and moves in the recess 40, so that the flexible detector 21 is kept in a free state without being elastically bent. .

  Then, as the detection member 30 moves, the interference portion 37 comes into contact with the locking protrusion 22 and pushes up the locking protrusion 22. As a result, as shown in FIG. 3, the flexure detection unit 21 is elastically bent upward, and only the flexure detection unit 21 of the cover 13 protrudes upward from the flange 23. The state of the elastic deflection of the flexure detection unit 21 can be easily confirmed visually from above (the outer surface side) of the cover unit 13 (first housing 10).

  When the detection member 30 reaches the detection position, the interference portion 37 passes through the locking projection 22, so that the flexible detection portion 21 elastically returns downward, and the locking projection 22 is engaged as shown in FIG. 1. The locking projections 22 and the locking recesses 38 are locked in the front-rear direction by being fitted into the locking recesses 38. By this locking action, the detection member 30 is locked at the detection position. Further, the manner in which the flexure detection unit 21 is elastically returned downward can be easily confirmed by visual observation from the upper side (outer surface side) of the cover part 13 (first housing 10), as in the case of elastic flexure upward. . Since the restricting projection 34 of the flexible arm portion 33 passes through the upper surface of the front end portion of the lock arm 17, the flexible arm portion 33 elastically returns downward.

  As described above, in the present embodiment, the rear end of the detection member 30 is exposed to the outer surface of the first housing 10 when the detection member 30 is in the standby position, and the detection member 30 is in the detection position. A cover portion 13 that covers the entire area of the detection member 30 in the front-rear direction is formed. Further, the cover portion 13 is formed with a flexible detection portion 21 that is exposed on the outer surface of the cover portion 13 and can be elastically bent in the vertical direction intersecting the moving direction of the detection member 30. Further, the detection member 30 is elastically bent by contacting the flexible detection unit 21 in the process of the detection member 30 moving from the standby position toward the detection position, so that the detection member 30 reaches the detection position. Along with this, an interference part 37 for elastically returning the flexure detection part 21 is formed.

  By adopting such a configuration, as to which position of the detection member 30 is in the standby position or the detection position, the detection member 30 is based on the longitudinal length of the portion exposed from the rear end of the cover portion 13. Can be determined. In addition, in the process in which the detection member 30 moves forward from the standby position and reaches the detection position, it is possible to visually confirm the operation in which the flexible detection unit 21 is elastically returned after being elastically bent once. It is possible to reliably determine that 30 has reached the detection position.

  Further, when the detection member 30 is in the standby position, the rear end portion of the detection member 30 is exposed from the cover portion 13, whereas when the detection member 30 moves to the detection position, the rear end portion of the detection member 30 is In the front-rear direction, the rear end of the cover member 13 is disposed at the same position, and the rear end of the detection member 30 enters the cover 13 and is not exposed. Accordingly, the position of the detection member 30 can be determined based on whether or not the rear end portion of the detection member 30 can be visually observed.

  Moreover, the formation area of the cover part 13 in the width direction is a range that covers the detection member 30 over the entire width thereof, and the cover part 13 includes the detection member 30 in the detection position in the cover part 13. A first cutout portion 19 and a second cutout portion 20 that expose a part of the detection member 30 are formed. Therefore, even when the detection member 30 moves to the detection position and enters the cover portion 13, a part of the detection member 30 is visually confirmed from the outside of the cover portion 13 through the first cutout portion 19 and the second cutout portion 20. it can. Thereby, it is possible to distinguish between a state in which the detection member 30 is attached to the first housing 10 and is in the detection position and a state in which the detection member 30 is not attached to the first housing 10.

  Further, the first cutout portion 19 and the second cutout portion 20 have a slit-like form cut out forward from the rear end of the cover portion 13 and are arranged so as to form a pair with an interval in the width direction. A portion between the first cutout portion 19 and the second cutout portion 20 forming the pair is a flexible detection portion 21. Thus, since the slit for forming the flexible detector 21 also has the function as the notches 19 and 20 for visually confirming the presence of the detection member 30 in the cover 13, the flexible detection is performed. The shape of the cover portion 13 can be simplified as compared with the case where a dedicated notch portion for visual confirmation is formed separately from the slit for forming the portion 21.

  Further, in a state where the detection member 30 moves to the detection position and the flexible detection unit 21 is elastically restored, the interference unit 37 is locked from the front with respect to the locking projection 22 of the flexible detection unit 21, thereby detecting The movement of the member 30 to the standby position side is regulated. Thus, since the flexible detection part 21 and the interference part 37 also have a lock function that restricts the movement of the detection member 30 to the standby position side, the first is compared with the case where a dedicated lock means is provided. The shapes of the housing 10 and the detection member 30 can be simplified.

  Further, at the rear end portion of the detection member 30, there are provided an interference portion 37 and an operation portion 35 that is arranged at a position behind the interference portion 37 and enables a pressing operation from the rear. . Thus, in this embodiment, since the operation part 35 was arrange | positioned behind the interference part 37, when pressing operation with respect to the operation part 35 from back is performed, the interference part 37 and the flexible detection part 21 operate | move. There is no risk of hindrance.
