Description

  The present invention relates to a structure of a joint connector housing.

  Conventionally, a joint connector for connecting a plurality of electric wires to each other has been used. Such a joint connector is described in Patent Document 1 and Patent Document 2, for example.

  The joint connector disclosed in Patent Literature 1 and Patent Literature 2 includes a connector housing (female terminal holder) that holds female terminals in a line. This connector housing can be stacked vertically and inserted into a male connector.

  Patent Document 2 discloses a configuration in which, when stacking connector housings, double locking ribs projecting from each connector housing are inserted into the locking holes of adjacent connector housings.

  13 and 14 schematically show the configuration of the connector housing (female housing) 90 of Patent Document 2. FIG. The connector housing 90 is formed with a terminal holding portion 93 into which the female terminal 5 can be inserted. FIG. 13B shows a state where the female terminal 5 is completely inserted into the terminal holding portion 93 (complete insertion). On the other hand, FIG. 13C shows a state (half-insertion) in which the female terminal 5 is inserted into the terminal holding portion 93 incompletely (halfway).

  As described above, the connector housing 90 includes the locking rib (double locking rib) 91 and the locking hole 92. The locking hole 92 is formed to communicate the space inside the terminal holding portion 93 and the outside of the connector housing 90. As described above, the connector housing 90 is configured to be able to be stacked. By laminating the connector housings 90, the locking ribs 91 of the adjacent connector housings 90 enter the terminal holding portion 93 through the locking holes 92. This is shown in FIG.

  FIG. 14A shows a state in which the connector housing 90 is stacked when the female terminal 5 is completely inserted. The locking rib 91 is configured such that its tip does not contact the female terminal 5 in a state of being completely inserted into the terminal holding portion 93 of another adjacent connector housing 90. For this reason, when the female terminal 5 is completely inserted, the locking rib 91 can be advanced to the end, so that the connector housings 90 can be brought into close contact with each other as shown in FIG. it can.

  On the other hand, FIG. 14B shows a state in which the connector housing 90 is stacked when the female terminal 5 is in a half-inserted state. The locking rib 91 is configured such that the tip thereof contacts the female terminal 5 in a state where it is incompletely inserted into the terminal holding portion 93 of another adjacent connector housing 90 (halfway). . Thus, if the front-end | tip of the latching rib 91 contacts the female terminal 5, the said latching rib 91 cannot be advanced further. For this reason, when the female terminal 5 is incompletely inserted (in the case of half insertion), the connector housings 90 cannot be brought into close contact with each other, and as shown in FIG. There is a gap t1 between them.

  Therefore, the locking rib 91 can be used as a means for detecting half insertion of the female terminal 5. In other words, if the connector housings 90 can be brought into close contact with each other when the connector housings 90 are stacked, the assembling operator can determine that the female terminals 5 are completely inserted. On the other hand, when the connector housing 90 is stacked, if the gap t1 is left between the connector housings 90, the assembling operator can determine that any of the female terminals 5 is in a half-inserted state.

JP 2004-1111279 A JP 2005-123109 A

  By the way, the longer the locking rib 91 is in the stacking direction, the larger the gap t1 generated between the connector housings 90 when the female terminal 5 is in the half-inserted state. Therefore, from the viewpoint of facilitating detection of half insertion of the female terminal 5, it is preferable that the locking rib 91 is longer in the stacking direction.

  On the other hand, if the locking rib 91 is made too long, the tip of the locking rib 91 comes into contact with the female terminal 5 in a completely inserted state. In this case, a gap is generated between the connector housings 90 even when the female terminal 5 is completely inserted (the state shown in FIG. 14A). Therefore, the locking rib 91 must be formed short in the stacking direction so that the tip of the locking rib 91 does not contact the fully inserted female terminal 5. For this reason, in the conventional joint connector, the gap t1 cannot be increased.

  As described above, since the gap t1 cannot be increased with the conventional joint connector, there is a problem that it is difficult for the assembly operator to notice that the female terminal 5 is half-inserted. For this reason, the joint connector is assembled while the female terminal 5 is in the half-inserted state, and as a result, there is a possibility that problems such as poor contact occur.

  The present invention has been made in view of the above circumstances, and a main object thereof is to provide a joint connector having a configuration capable of reliably detecting a half-inserted state of a female terminal.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to an aspect of the present invention, there is provided the following configuration of a joint connector including a plurality of stacked housings and a inserted housing that can be inserted in a state where the plurality of stacked housings are stacked in the stacking direction. That is, the stacked housing includes a terminal holding portion into which a terminal is inserted, and a locking rib that protrudes along the stacking direction and enters a terminal holding portion of another adjacent stacked housing. In the state in which the plurality of stacked housings are stacked, the locking rib is configured such that the tip thereof contacts the terminal that is incompletely inserted into the terminal holding portion of the adjacent stacked housing that is adjacent to the stacked housing. Has been. And in the state which laminated | stacked these several laminated | stacked housings, the extension line | wire to the lamination direction of the said latching rib does not interfere with the terminal completely inserted in the said terminal holding | maintenance part of the said other adjacent laminated | stacked housing. It is configured as follows.

  In this way, by configuring the tip of the locking rib to contact the half-inserted (inserted halfway) terminal, there is a gap between the stacked housings when a plurality of stacked housings are stacked. Since this occurs, the half insertion can be detected. Since the extension line of the locking rib is configured not to interfere with the completely inserted terminal, even if the locking rib is set to be long, the tip of the locking rib is connected to the fully inserted terminal. There is no contact. Therefore, the locking rib can be lengthened. By lengthening the locking rib, when the terminal is half-inserted, a large gap is formed between the stacked housings, so that the half-insertion can be easily detected.

  The joint connector is preferably configured as follows. That is, the terminal is formed with a notch in the shape of a projection wheel when viewed from the side. The terminal holding unit holds the terminal such that the side surface of the terminal is orthogonal to the stacking direction. The locking rib is disposed so as to enter inside the notch portion of the terminal that is completely inserted into the terminal holding portion of the other adjacent laminated housing.

  Thus, since it was set as the structure which makes the inside of the said notch part approach the inside of the said notch part with respect to the terminal in which the notch part was formed, even if the said retaining rib was set long, the said latching The tip of the rib does not contact the fully inserted terminal. Therefore, the locking rib can be set longer.

  In the joint connector described above, the length of the locking rib in the stacking direction can be at least half the width of the terminal in the stacking direction.

  In the joint connector, it is preferable that the stacked housing includes a plurality of lock portions that are engaged with adjacent stacked housings when a plurality of stacked housings are stacked with the locking rib interposed therebetween.

  That is, if there is only one lock portion, even if there is a gap between the stacked housings, the lock portion may be able to be engaged with force. In this regard, if the lock portions are provided at a plurality of locations, all the lock portions cannot be engaged when there is a gap between the stacked housings. Thereby, it can be easily detected that a gap is generated between the stacked housings.

  The joint connector is preferably configured as follows. That is, the joint connector includes a cover member that has the locking rib and does not have the terminal holding portion. Each of the stacked housings and the locking ribs of the cover member are provided only on one side in the stacking direction. And the said cover member is arrange | positioned adjacent to the to-be-stacked housing located in the edge of the side in which the said latching rib is not provided among the some to-be-stacked housings laminated | stacked.

  That is, since the locking rib is provided only on one side in the stacking direction, when a plurality of stacked housings are stacked, the terminal holding of the stacked housing located at the end on the side where the locking rib is not provided is performed. The engaging ribs of other adjacent stacked housings are not inserted into the portion. Therefore, as described above, by providing the cover member having the locking rib, the locking rib can be caused to enter the terminal holding portion of the stacked housing located at the end on the side where the locking rib is not provided. .

  The joint connector is preferably configured as follows. That is, the locking rib of each stacked housing is provided only on one side in the stacking direction. The insertion housing is fitted into the locking rib formed on the stacked housing located at the end of the stacked stacked housings on the side where the locking rib is provided. A part. The fitting portion is formed in a groove shape along the insertion direction of the laminated housing.

  By providing the groove-shaped fitting portion along the insertion direction and guiding the locking rib by the fitting portion, a plurality of stacked laminated housings can be smoothly inserted into the insertion housing. . Further, since the locking rib is provided only on one side in the stacking direction of the stacked housing, when the stacked housing is to be inserted, for example, in the opposite direction by 180 degrees, the fitting portion is fitted into the locking rib. Can't match. Accordingly, it is possible to prevent the stacked housing from being inserted in the opposite direction with respect to the inserted housing.

FIG.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a joint connector 1 according to the present embodiment.

  As shown in FIG. 1, a number of electric wires 2 are connected to the joint connector 1. The joint connector 1 includes a male housing (inserted housing) 3 and a female housing (stacked housing) 4.

  As shown in FIG. 2, the male housing 3 is configured so that a female housing 4 can be inserted. A direction in which the female housing 4 is inserted into the male housing 3 (a direction indicated by a thick arrow in FIG. 2) is referred to as an insertion direction.

  As shown in FIG. 2, a female terminal 5 is provided at the end of each electric wire 2. The female housing 4 is formed with a plurality of terminal holding portions 6 into which the female terminals 5 can be inserted in the insertion direction. On the other hand, a male terminal (not shown) that fits into the female terminal 5 is appropriately disposed inside the male housing 3. Then, by inserting the female housing 4 into the male housing 3, the male terminal is fitted to the female terminal 5 held by the female housing 4. Thereby, predetermined electric wires 2 can be electrically connected in a predetermined pattern.

  As shown in FIGS. 2 and 3, the female housing 4 is configured such that a plurality of female housings 4 can be stacked in a direction orthogonal to the insertion direction. A direction in which the female housings 4 are stacked is referred to as a stacking direction. Each female housing 4 has a plurality of terminal holding portions 6 arranged in a direction perpendicular to the stacking direction and the insertion direction. The direction in which the terminal holding portions 6 are arranged in each female housing 4 is referred to as a terminal holding direction. In addition, the female housing 4 of this embodiment has the four terminal holding parts 6 each. Further, the joint connector 1 of the present embodiment is configured to be inserted into the male housing 3 in a state where six female housings 4 are stacked. Therefore, the joint connector of this embodiment can connect a total of 24 wires 2.

  As shown in FIG. 4, the female housing 4 is formed with a lock portion including a lock claw 7 and an engagement portion 8. The lock claw 7 is configured to be engageable with an engaging portion 8 of another female housing 4 adjacent in the stacking direction. By engaging the lock claw 7 of each female housing 4 with the engaging portion 8 of another adjacent female housing 4, the female housings 4 can be fixed in a stacked state (state shown in FIG. 2). In the female housing 4 of this embodiment, four lock claws 7 and four engaging portions 8 are formed. As described above, the female housings 4 can be stably fixed to each other by providing a plurality of lock portions (the lock claws 7 and the engaging portions 8).

  The configuration of the female terminal 5 is illustrated in FIG. As the female terminal 5, a known one that is commercially available can be used. As shown in FIG. 5A, the female terminal 5 includes a crimping portion 11 that is crimped to the conductor 10 included in the electric wire 2. In the female terminal 5, a surface on which the caulking portion 11 presses the conductor 10 is defined as a bottom surface 13 of the female terminal 5. In addition, a surface that rises from the bottom surface 13 in a direction substantially perpendicular to the bottom surface 13 and is substantially parallel to the insertion direction is defined as a side surface 14 of the female terminal 5.

  As shown in FIG. 5 (b), when the female terminal 5 is viewed from the side surface 14, a notch 9 is formed in the projection ring shape of the female terminal 5.

  FIG. 6 shows a cross-sectional view of the female housing 4. As shown in FIG. 6, the terminal holding part 6 is formed as an elongated space formed along the insertion direction. Thereby, the female terminal 5 can be inserted in the terminal holding part 6 along the insertion direction. Each terminal holding part 6 is provided with an engaging part 15 that engages with the inserted female terminal 5 to prevent the female terminal 5 from coming off. In addition, as shown to Fig.6 (a), the engaging part 15 is formed in the inner wall surface (upper wall surface of Fig.6 (a)) of the one terminal holding direction in each terminal holding part 6. As shown in FIG. .

  As shown in FIGS. 6B and 6C, a locking rib 16 is formed on one surface of the female housing 4 in the stacking direction. The locking rib 16 is formed so as to protrude along the stacking direction. On the other hand, a locking hole 17 is formed on the surface of the female housing 4 opposite to the locking rib 16 in the stacking direction. The locking hole 17 is formed so as to communicate the inner side of the terminal holding part 6 and the outer side of the female housing 4. A plurality of locking holes 17 are provided corresponding to each terminal holding portion 6. A plurality of locking ribs 16 are provided corresponding to the respective locking holes 17.

  As shown in FIG. 7, the locking rib 16 is configured to be inserted into a corresponding locking hole 17 of another adjacent female housing 4 when the female housings 4 are stacked. Therefore, in the state where the female housings 4 are stacked, the locking rib 16 of the adjacent female housing 4 enters the terminal holding portion 6 of each female housing 4.

  FIG. 7 shows a state in which the female housing 4 is stacked in a state where the female terminal 5 is not held on the terminal holding portion 6, but this is for easy understanding of the drawing. In the actual assembly work of the joint connector 1, the female housing 4 is stacked in a state where the female terminal 5 is inserted into each terminal holding portion 6 of each female housing 4.

  As shown in FIG. 8, the terminal holding portion 6 of the female housing 4 of the present embodiment is configured to hold the female terminal 5 in a posture in which the side surface 14 of the female terminal 5 is directed in the stacking direction.

  FIG. 9 shows a state (half insertion) in which the female terminal 5 is incompletely inserted into the terminal holding portion 6. As shown in FIG. 9A, the locking hole 17 is configured to be partially blocked by the side surface of the female terminal 5 half inserted when viewed in the stacking direction. Further, the state of the female terminal 5 in the half-inserted state is shown by a cross section of the lowermost female terminal 5 in FIG. As shown in FIG. 11, with respect to the extension line 20 in the stacking direction of the locking rib 16 inserted into the locking hole 17, the female terminal 5 in the half-inserted state (the lowest female terminal 5 in FIG. 11). The side surface 14 of this is configured to interfere.

  With this configuration, when the female housing 4 is stacked with the female terminal 5 half inserted, the tip of the locking rib 16 of the adjacent female housing 4 is positioned as shown in FIG. , Contacts the side surface of the female terminal 5. When the locking rib 16 comes into contact with the female terminal 5, the locking rib 16 cannot enter further, so that a gap t <b> 2 is generated between the female housings 4. Thereby, half insertion of the female terminal 5 can be detected.

  Note that when the tip of the locking rib 16 comes into contact with the female terminal 5, the female terminal 5 pushed by the locking rib 16 may rotate inside the terminal holding portion 6. Therefore, in this embodiment, the holding rib 24 that protrudes in parallel with the locking rib 16 is formed in the female housing 4. As shown in FIG. 11, the holding rib 24 is on one side in the terminal holding direction with respect to the stabilizer 25 (see FIG. 5) of the female terminal 5 in the half-inserted state (lower female terminal 5 in FIG. 11). It is formed in the position which can contact from. Thus, even when the female terminal 5 in the half-inserted state is pressed by the locking rib 16, the female terminal 5 is held by the terminal holding portion 6 by pressing the stabilizer 25 of the female terminal 5 by the pressing rib 24. Can be prevented from rotating inside.

  FIG. 10 shows a state where the female terminal 5 is completely inserted into the terminal holding portion 6. As shown in FIG. 10A, the locking hole 17 is configured not to be blocked by the completely inserted female terminal 5 when viewed in the stacking direction. More specifically, when viewed in the stacking direction, the locking hole 17 is formed so as to be positioned inside the notch 9 of the female terminal 5 that is completely inserted.

  Moreover, the state of the female terminal 5 in the completely inserted state is shown by the cross sections of the first and second female terminals 5 from the top in FIG. As shown in FIG. 11, when the female terminal 5 is completely inserted, the extension line 20 in the stacking direction of the locking rib 16 inserted into the locking hole 17 extends from the female terminal 5 (from the top of FIG. 11). The first and second female terminals 5) are configured not to interfere with each other. The extension line 20 passes through one side of the female terminal 5 in the fully inserted state in the terminal holding direction (the lower side of the female terminal 5 in FIG. 11). Accordingly, when the female housings 4 are stacked with the female terminals 5 fully inserted, the locking ribs 16 of the adjacent female housings 4 can enter the terminal holding portion 6 without contacting the female terminals 5. .

  Therefore, if the female terminal 5 is completely inserted into the terminal holding portion 6, the entire length of the locking rib 16 of the adjacent female housing 4 can enter the terminal holding portion 6. As a result, the female housings 4 can be brought into close contact with each other as shown in FIG.

  As described above, when viewed in the stacking direction, the locking hole 17 is formed so as to be positioned inside the notch 9 of the female terminal 5 that is completely inserted. Therefore, when the female terminal 5 is completely inserted, the locking rib 16 inserted from the locking hole 17 is positioned inside the notch 9 of the female terminal 5. The manner in which the locking rib 16 is located inside the notch 9 of the female terminal 5 is shown in FIGS. 10 (b) and 10 (c).

  Subsequently, a characteristic configuration of the joint connector 1 of the present embodiment will be described in detail.

  In the conventional configuration shown in FIGS. 13 and 14, the locking rib 91 is inserted so as to face the notch 9 formed in the female terminal 5. For this reason, in a state where the locking rib 91 enters the inside of the notch 9 (the state of FIG. 14A), the female terminal 5 exists on the extension line in the stacking direction of the locking rib 91. Yes. For this reason, the locking rib 91 could not be set long. Therefore, conventionally, the length of the locking rib 91 in the stacking direction is less than half the width of the female terminal 5 in the stacking direction.

  In this regard, in the present embodiment, the engaging rib 91 is configured to be inserted into the notch 9 from the side surface 14 side of the notch 9 formed in the female terminal 5 (that is, the present embodiment). In the configuration, the orientation of the female terminal 5 is 90 degrees different from the conventional configuration).

  Since it comprised in this way, in the state (state of FIG.10 (b) and FIG.10 (c)) in which the latching rib 91 entered the inside of the notch part 9, the extension line to the lamination direction of the said latching rib 91 Does not interfere with the female terminal 5. For this reason, even if the locking rib 91 is lengthened, the tip of the locking rib 91 does not contact the female terminal 5 in the fully inserted state. Therefore, the locking rib 91 can be set long. For example, in the present embodiment, as shown in FIG. 10B, the length of the locking rib 16 in the stacking direction is set to be approximately the same as the width of the female terminal 5 in the stacking direction.

  As described above, according to the configuration of the present embodiment, the locking rib 16 can be set longer than in the prior art. As a result, the gap t2 (FIG. 9B) generated between the female housings 4 when the female terminal 5 is half inserted can be made larger than the conventional gap t1 (FIG. 14B). This makes it easy to detect half insertion.

  Further, as described above, the female housing 4 includes the lock portions (the lock claws 7 and the engaging portions 8) that fix the adjacent female housings 4 to each other. When the female terminal 5 is half-inserted, the adjacent female housings 4 cannot be brought into close contact with each other, making it difficult to engage the lock claw 7 and the engaging portion 8. Therefore, when the lock claw 7 and the engaging portion 8 cannot be engaged, the assembling operator can easily determine that the female terminal 5 is half-inserted.

  However, even if the female terminal 5 is half-inserted, it is considered that there are cases where the lock portion can be forcedly engaged. Therefore, in this embodiment, as shown in FIG. 4B, the lock portions (the lock claws 7 and the engagement portions 8) are provided so as to be paired with the locking ribs 16 in the terminal holding direction. That is, when the female terminal 5 is half-inserted, a gap is left between the female housings 4 (the state shown in FIG. 12) even if any of the lock portions can be forcedly engaged. The other locking part cannot be engaged. As described above, when the female terminal 5 is half-inserted, all the lock portions cannot be forcedly engaged, so that the assembling operator can reliably detect half-insertion.

  As described above, the locking rib 16 of this embodiment is provided on one surface of the female housing 4 in the stacking direction. That is, the locking rib 16 is not provided on the other surface of the female housing 4. Therefore, when a plurality of female housings 4 are stacked, the female housing 4 (indicated by reference numeral 4a in FIG. 3) located at the end opposite to the side where the locking ribs 16 are provided is locked. There is no other female housing 4 into which the rib 16 is inserted.

  Therefore, in this embodiment, as shown in FIG. 3, the cover member 21 is disposed adjacent to the female housing 4a. The cover member 21 has a locking rib 16 and a lock claw 7. Note that the cover member 21 does not have a function of holding the female terminal 5. Then, the cover member 21 is stacked together with the female housing 4a and the other female housing 4 (state shown in FIG. 2) and inserted into the male housing 3.

  Thus, by laminating the cover member 21 and the female housing 4a, the locking rib 16 of the cover member 21 is inserted into the locking hole 17 of the female housing 4a. Thereby, the assembly operator can detect half insertion of the female terminal 5 also in the female housing 4a.

  When the plurality of female housings 4 are stacked, the locking ribs 16 of the female housing 4 (indicated by reference numeral 4b in FIGS. 2 and 3) located at the end on the side where the locking ribs 16 are provided are: The other female housing 4 is not inserted. Therefore, as shown in FIG. 2, in the state where the plurality of female housings 4 are stacked, the locking ribs 16 of the female housing 4b protrude in the stacking direction.

  As shown in FIG. 2, the male housing 3 of the present embodiment has a fitting portion 22. The fitting portion 22 is formed so as to be fitted to the locking rib 16 of the female housing 4b when the stacked female housing 4 is inserted into the male housing 3. Specifically, the fitting portion 22 is formed in a groove shape parallel to the insertion direction on the inner wall surface of the male housing 3. Thereby, when inserting the laminated | stacked female housing 4 in the male housing 3 (FIG. 2), the latching rib 16 of the female housing 4b can be guided by the groove-shaped fitting part 22. FIG.

  In addition, as shown in FIG. 2, in the male housing 3, the wall surface 23 facing the wall surface on which the fitting portion 22 is formed is not configured to be fitted to the locking rib 16. Therefore, even if the stacked female housing 4 is to be inserted in the reverse direction (in the wrong direction), the locking rib 16 of the female housing 4 b interferes with the wall surface 23. This prevents the stacked female housing 4 from being inserted in the opposite direction (in the wrong direction) with respect to the male housing 3.

  As described above, the female housing 4 of the present embodiment protrudes along the stacking direction with the terminal holding part 6 into which the female terminal 5 is inserted, and enters the terminal holding part 6 of another adjacent female housing 4. Locking ribs 16 to be used. In a state where the plurality of female housings 4 are stacked, the locking rib 16 is configured such that the tip thereof contacts the female terminals 5 that are incompletely inserted into the terminal holding portions 6 of the other adjacent female housings 4. ing. And in the state which laminated | stacked the several female housing 4, the extension line 20 to the lamination direction of the latching rib 16 does not interfere with the female terminal completely inserted in the terminal holding | maintenance part 6 of the other adjacent female housing 4. FIG. It is configured as follows.

  As described above, the female terminals 5 that are half inserted (inserted halfway) are configured such that the tips of the locking ribs 16 are in contact with each other. Since the gap t2 is generated in the half-insertion, the half-insertion can be detected. And the locking rib 16 can be set long by setting the extension line of the said locking rib 16 so that it may not interfere with the female terminal 5 inserted completely. By lengthening the locking rib 16, when the female terminal 5 is half-inserted, a large gap t2 is opened between the female housings 4, so that the half-insertion can be easily detected.

  Further, in the present embodiment, the female terminal 5 is formed with a notch 9 in a projection ring shape when viewed from the side surface 14 side. The terminal holding part 6 holds the female terminal 5 with the side surface 14 of the female terminal 5 facing in the stacking direction. The locking rib 16 is disposed so as to enter the inside of the notch 9 of the female terminal 5 that is completely inserted into the terminal holding portion 6 of the other adjacent female housing 4.

  Thus, the latching rib 16 can be set long by laminating the female terminals 5 in the side surface direction.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  The shapes of the male housing 3 and the female housing 4 are not limited to those shown in the drawings, and can be changed as appropriate according to the application.

  Although the terminal held in the laminated housing (female housing 4) is a female terminal, it may be a male terminal or a hermaphroditic terminal.
