Description

TECHNICAL AREA

[0001] The present invention relates to a connector. BACKGROUND

[0002] A conventional connector of this type is proposed, as disclosed in JP 2013-055018 A. JP 2013-055018 A discloses a connector comprising a housing and a locking mechanism attached to the housing. JP 2013-055018 A discloses that the locking mechanism is mounted on the housing in a state where it can slide between a temporary locking position and a final locking position. A first locking projection and a second locking projection are formed on the locking mechanism.

[0003] By engaging the first locking projection with a final locking section formed in the housing, the detent is held in a final locked position by the housing when the detent is moved into the final locked position. By engaging the second locking projection with a section formed in the housing to increase the locking force when the detent is moved into the final locked position, it is possible to suppress any play in the detent held by the housing in the final locked position.

[0004] In this way, JP 2013-055018 A discloses that the detent has the first locking projection as a locking section and the second locking projection as a backlash-filling section. This ensures that when the detent is finally locked to the housing, it is held by the housing in a state where backlash is suppressed. SUMMARY OF THE INVENTION

[0005] In this way, in the connector with the locking mechanism held by the housing, the holding force between the locking mechanism and the housing in the final locking state can preferably be ensured more reliably in a state where the play is suppressed.

[0006] One object of the present invention is to provide a connector that can more reliably ensure the holding force between a locking mechanism and a housing, while suppressing any play in the locking mechanism in a final locked state.

[0007] A connector according to one aspect of the present invention comprises: a housing configured such that a cavity in which a connector is housed extends in a first direction;and a locking device which is inserted into the housing from one side in a second direction which intersects the first direction, and which is mounted on the housing in a state in which the locking device can slide between a temporary locking position in which the locking device is temporarily locked to the housing, and a final locking position in which the locking device is finally locked to the housing, wherein the locking device comprises: a base section which allows the connector to be inserted into and removed from the cavity when the locking device is in the temporary locking position, and which engages with the connector housed in the cavity and governs the separation of the connector from the cavity when the locking device is in the final locking position;and a side wall section continuously connected to an end of the base end section in a third direction intersecting the first direction and the second direction, wherein a length of the side wall section in the first direction is longer than a length of the base section in the first direction, the side wall section having a locking section facing the housing in the third direction and locking to the housing when the detent is in the final locking position;and a clearance-filling section projecting outwards in the third direction and abutting the housing when the detent is in the final locking position, wherein the locking section is configured such that at least part of the locking section is located on a part of the side wall section projecting from the base section in the first direction, and when the detent is viewed in the third direction, the clearance-filling section is configured in a position spaced apart from the locking section in the first direction.

[0008] The present invention makes it possible to provide a connector that can more reliably ensure the holding force between a locking mechanism and a housing, while suppressing play in the locking mechanism in a final locked state.

[0009] Various embodiments are described below with reference to the attached drawings.

[0010] A connector according to the present embodiment is described in detail below with reference to the drawings. It should be noted that the dimensions in the drawings are exaggerated for illustrative purposes and may differ from the actual dimensions.

[0011] Furthermore, in the following embodiment, a direction in which a connector is inserted into a housing is defined and explained as the X-direction (first direction: front and back direction). A direction in which a locking device is inserted into the housing (sliding direction of the locking device relative to the housing) is defined and explained as the Z-direction (second direction: up and down direction). Furthermore, a direction that intersects the X-direction (first direction: front and back direction) and the Z-direction (second direction: up and down direction) is defined and explained as the Y-direction (third direction: width direction).

[0012] Furthermore, an upward and downward direction for each element is defined and explained, in a state where the locking mechanism is inserted into the housing by moving the locking mechanism of a connector relative to the housing from bottom to top. When the connector is attached to a mating connector, the side facing the mating connector is defined and explained as the front in both the front and rear directions.

[0013] A connector 1 according to the present embodiment can be used as a connector for a motor vehicle and can be used for the electrical connection between electrical components, such as between a power source and a device or between a device and a machine. The component 1 is electrically connected to an electrical component of the electrical components and is provided with a mating connector (not shown) that is electrically connected to the other electrical component of the electrical components. In the present embodiment, the mating connector is assumed to be a plug and the connector 1 a socket. One or more wires (not shown) that are electrically connected to the electrical components are individually connected to the connector 1 via terminals 6.

[0014] Each connector 6 is formed approximately in the shape of a rod using a conductive material and is connected to a terminal of each wire. Each connector 6 has a connecting section 61, a coupling section 62, and an intermediate section 63.

[0015] The connecting section 61 is a section to which a terminal of the mating connector is externally connected. The shape of the connecting section 61 can be approximately box-shaped, so that the connecting section 61 can be inserted into a tab-shaped connecting section that is arranged at the terminal of the mating connector. At this point, an elastic part with a contact portion that touches the mating connecting section is arranged inside the connecting section 61. Furthermore, a locking section 61a is (see Fig. 1) formed on an outer surface of the connecting section 61, and the locking section 61a can be locked with a locking projection (not shown) of a lance formed in a housing 2, which will be described later. An engagement recess 61b, which engages with a connecting engagement section 41b of a detent 3 described later, is formed at a lower end of the intermediate section 63.

[0016] Furthermore, a wire is coupled to the coupling section 62 of each connector 6. The coupling section 62 can comprise a conductor crimping tool, consisting of a pair of pressure-fastening parts, and a sheath-fastening section, also consisting of a pair of pressure-fastening parts. The conductor crimping tool is crimped to a conductor of the wire by pressing the pair of pressure-fastening parts together. Each connector 6 is electrically connected to the wire by crimping the conductor crimping tool to the conductor of the wire. Meanwhile, the sheath-fastening section is attached to a sheath of the wire by pressing the pair of pressure-fastening parts together. Each connector 6 is attached to the wire by pressing the fitting section against the sheath of the wire.

[0017] The intermediate section 63 is arranged between the connecting section 61 and the coupling section 62 and serves to integrate the connecting section 61 and the coupling section 62.

[0018] In this embodiment, the connector 1 has the connecting pieces 6. Furthermore, the connector 1 has the housing 2 with cavities 25 in which the connecting pieces 6 are housed, and the locking device 3 inserted into the housing 2.

[0019] The housing 2 is formed from an insulating material, such as synthetic resin, and is a housing element that is attached, for example, to a mating connector housing of the connector. As in the present embodiment, if the connector is a female connector, the housing can be referred to as the female housing.

[0020] In the present embodiment, the housing 2 has an upper wall 21, a bottom wall 22 facing the upper wall 21 in a Z-direction (second direction: upward and downward direction), and a pair of side walls 23 connected successively to the ends of the upper wall 21 and the bottom wall 22 in a Y-direction (third direction: width direction). The housing 2 has an approximately rectangular parallelepiped shape and is shaped such that, in a front view (when the housing 2 is viewed along the X-direction), it has an approximately elongated rectangular shape in the Y-direction (third direction: width direction).

[0021] In the present embodiment, the upper wall 21 has a guide projection 211 that is inserted into a guide groove formed in the mating connector, and a locking element 212 that engages with a locking mechanism formed on the mating connector when the connector 1 is attached to the mating connector. Furthermore, the bottom wall 22 also has a guide projection 221 that is inserted into the guide groove formed in the mating connector, and a locking element 222 that engages with the locking mechanism formed on the mating connector when the connector 1 is attached to the mating connector. The side wall 23 also has a guide projection 231 that is inserted into the guide groove formed in the mating connector, and a locking element 232 that engages with the locking mechanism formed on the mating connector when the connector 1 is attached to the mating connector.

[0022] A multitude of cavities 25, which run in an X direction (first direction: front and rear direction), are formed in the housing 2.

[0023] In the present embodiment, three types of cavities 25 are formed in the housing 2. Specifically, the three types of cavities 25, i.e., a first cavity 251, a second cavity 252, and a third cavity 253, are formed in the housing 2. In the present embodiment, the first cavity 251 is a cavity 25 whose cross-section is relatively large when cut in a YZ plane. The second cavity 252 is a cavity 25 whose cross-sectional area when cut in the YZ plane is smaller than the cross-sectional area of ​​the first cavity 251. Furthermore, the third cavity 253 is a cavity 25 whose cross-sectional area when cut in the YZ plane is smaller than the cross-sectional area of ​​the second cavity 252.

[0024] Three types of connectors 6 of different sizes are accommodated individually in the three types of cavities 25.

[0025] Specifically, a first connector 6A of the largest size is inserted into the first cavity 251 from the rear in the X direction (first direction: front and rear direction), and the first connector 6A is housed in the first cavity 251. The first connector 6A can be used, for example, as a connection for a power source.

[0026] Furthermore, a second connector 6B of an intermediate size is inserted into the second cavity 252 from the rear in the X direction (first direction: front and rear), and the second connector 6B is received in the second cavity 252. The second connector 6B can be used, for example, as a grounding connection.

[0027] A third connector 6C, the smallest size, is inserted from the rear in the X direction (first direction: front and rear) into the third cavity 253, and the third connector 6C is housed in the third cavity 253. The third connector 6C can be used, for example, as a signal connector.

[0028] Fig. Figure 1 shows an example where six connectors (first connector 6A, second connector 6B, and third connector 6C) of different sizes but approximately the same shape are used as the three types of connectors. However, other connectors with different sizes and shapes can also be used.

[0029] Furthermore, in the present embodiment, two first cavities 251 are formed on one side of the Y-direction (third direction: width direction) of the housing 2, such that the first cavities 251 are oriented in the Y-direction (third direction: width direction). In addition, a plurality of second cavities 252 and a plurality of third cavities 253 are formed on the other side of the Y-direction (third direction: width direction) of the housing 2. In particular, on the other side of the Y-direction (third direction: width direction) of the housing 2, three rows are formed in the Z-direction (second direction: upward and downward direction), and in each row, a plurality of cavities 25 are arranged side by side in the Y-direction (third direction: width direction).The cavities 25 in the top row are second cavities 252, and six second cavities 252 are formed such that the second cavities 252 are oriented in the Y-direction (third direction: width direction). Furthermore, the cavities 25 in the middle row and the cavities 25 in the bottom row are third cavities 253, and in each row, ten third cavities 253 are formed such that the third cavities 253 are oriented in the Y-direction (third direction: width direction).

[0030] Furthermore, in the present embodiment, the housing 2 has a partition 24, and the partition 24 separates an area in which the first cavities 251 are formed from an area in which the second cavities 252 and the third cavities 253 are formed.

[0031] Furthermore, the housing 2 has an insertion chamber 26 for the locking device, into which the locking device can be inserted, such that the insertion chamber 26 for the locking device is open on one side (underside) in the Z-direction (second direction: upward and downward direction). The locking device can be held by the housing 2 by inserting it through the opening.

[0032] In the present embodiment, as in Fig. 2 and Fig. As shown in Figure 3, the insertion space 26 for the locking mechanism has a first insertion space 261 for the locking mechanism, which is configured to intersect the two first cavities 251 in the Y-direction (third direction: width direction) at a central part in the X-direction (first direction: front and rear direction). Furthermore, the insertion space 26 of the locking mechanism has a second insertion space 262 of the locking mechanism, which is configured to intersect the plurality of second cavities 252 and third cavities 253 in the Y-direction (third direction: width direction) at the central part in the X-direction (first direction: front and rear direction).

[0033] By inserting the locking device 3 into the first insertion chamber 261 of the locking device and finally locking the locking device 3, the first connector 6A, which is housed in the first cavity 251, is doubly locked. That is, the first connector 6A, which is housed in the first cavity 251, is engaged with the engagement section 41b formed on the locking device 3, while it is locked with a lance formed in the first cavity 251. In this way, it is possible to increase the holding force of the first connector 6A by the housing 2, and the first connector 6A, which is housed in the first cavity 251, can be more reliably prevented from falling out of the housing 2.

[0034] In the present embodiment, connector 1 is shown as an example where the locking mechanism is not inserted into the second insertion space 262 of the locking mechanism. However, it is also possible to use a connector 1 where the locking mechanism is inserted into the second insertion space 262.

[0035] Furthermore, in the present embodiment, as in Fig. Figure 3 shows that the first locking insertion chamber 261 has an inner insertion chamber 261a, which has an approximately rectangular shape and is elongated in the Y-direction (third direction: width direction) in plan view. Furthermore, the first locking insertion chamber 261 has a pair of outer insertion chambers 261b, which follow one another on both sides of the inner insertion chamber 261a in the Y-direction (third direction: width direction) and project further on the rear side in the X-direction (first direction: front and rear direction) than the inner insertion chamber 261a. Thus, in the present embodiment, a length W2 of the outer insertion chambers 261b in the X-direction (first direction: front and rear direction) of the first locking insertion chamber 261 is longer than a length W1 of the inner insertion chamber 261a in the X-direction (first direction: front and rear direction).

[0036] When the locking device 3 is inserted into the first locking insertion chamber 261, a base section 4 of the locking device 3 is inserted into the inner insertion chamber 261a, and a pair of side wall sections 5 are inserted into the outer insertion chambers 261b. When the locking device 3 is inserted into the first insertion chamber 261 of the locking device, the ends of the locking device 3 are arranged in the Y-direction (third direction: width direction) between a side wall of the side walls 23 and the partition 24 of the housing 2.

[0037] Furthermore, in the present embodiment, as in Fig. Figure 5 shows wall sections 2611 and a concave section 2612 formed within the first insertion space 261 of the locking device. In particular, a pair of wall sections 2611 is configured such that they are separated from each other in the Y-direction (third direction: width direction). The concave section 2612 is formed between the pair of wall sections 2611. In the present embodiment, each of the two wall sections 2611 has an upper wall section 26111, which is wider in the Y-direction (third direction: width direction), and a lower wall section 26112, which adjoins a lower end of the upper wall section 26111 and has a smaller width in the Y-direction (third direction: width direction) than the upper wall section 26111.Furthermore, the concave section 2612 has an upper concave section 26121, which is narrower in the Y direction (third direction: latitude direction), and a lower concave section 26122, which is successively connected to a lower end of the upper concave section 26121 and has a greater width than the upper concave section 26121 in the Y direction (third direction: latitude direction).

[0038] The locking device 3, which has a shape corresponding to the shape of the first insertion space of the locking device 261, is inserted into the first insertion space of the locking device 261.

[0039] In particular, locking mechanism 3, as shown in the Fig. 6, Fig. 7, Fig. 8 to Fig. Figure 9 shows the base end section 4 and the pair of side wall sections 5, which are successively connected to the ends 4a on both sides of the base end section 4 in the Y direction (third direction: width direction).

[0040] The pair of side wall sections 5 is configured such that a length W4 of the pair of side wall sections 5 in the X-direction (first direction: front and rear direction) is longer than a length W3 of the base section 4 in the X-direction (first direction: front and rear direction). In particular, the two side wall sections 5 are shaped such that they project beyond the base section 4 on the rear side in the X-direction (first direction: front and rear direction).

[0041] In this embodiment, the shapes of the first insertion chamber of the locking device 261 and the locking device 3 (contour shapes in top view) are adjusted such that both ends project in the same direction (rear side in the front and rear directions). If the locking device 3, which points in the opposite direction, is inserted into the first insertion chamber 261 of the locking device, the two sections of the side wall 5 interfere with the bottom wall 22 of the housing 2 and prevent insertion. In this way, accidental insertion of the locking device 3 can be prevented in the present embodiment by adjusting the shapes of the first insertion chamber 261 of the locking device and the locking device 3 (contour shapes in top view) such that both ends project in the same direction (rear side in the front and rear directions).

[0042] Furthermore, in the present embodiment, the locking device 3 is attached to the housing 2 in a state in which the locking device 3 can slide between a temporary locking position, in which the locking device 3 is temporarily locked to the housing 2, and a final locking position, in which the locking device 3 is finally locked to the housing 2.

[0043] In particular, a locking projection 531 is arranged on each of the two side wall sections 5, and a temporary locking projection 241 and a final locking projection 242, which are located above the temporary locking projection 241, are each arranged on an inner wall of one of the side walls 23 and an inner wall of the partition wall 24 of the housing 2.

[0044] The detent 3 is then inserted from below into the first insertion chamber 261 of the detent, and the locking section 531 is locked with the temporary locking projection 241. This holds the detent 3 in a temporary locked state by the housing 2.

[0045] Furthermore, the detent 3, which is held in the temporary locked state by the housing 2, is pushed upwards, and the locking section 531 is locked with the final locking projection 242. As a result, the detent 3 is held in a final locked state by the housing 2.

[0046] Based on the above explanations, the locking device 3 is attached to the housing 2 in a state in which the locking device 3 can slide between the temporary locking position, in which the locking device 3 is temporarily locked to the housing 2, and the final locking position, in which the locking device 3 is finally locked to the housing 2.

[0047] In the present embodiment, as in Fig. 11 and Fig. As shown in Figure 13, the temporary locking projection 241 has a lower inclined surface 2411, inclined inwards and upwards in the Y-direction (third direction: width direction), and a vertical surface 2412, which is successively connected to an upper end of the lower inclined surface 2411. Furthermore, the temporary locking projection 241 has an upper horizontal surface 2413, which is successively connected to an upper end of the vertical surface 2412 and extends horizontally.

[0048] Furthermore, the locking section 531 has a lower horizontal surface 5311 extending outwards in the Y-direction (third direction: width direction) and an upper inclined surface 5312 inclined inwards and upwards in the Y-direction (third direction: width direction). In this embodiment, the locking section 531 is thus configured on each of the side wall sections 5 such that the locking section 531 projects in the Y-direction (third direction: width direction) while facing the housing 2 in the Y-direction (third direction: width direction).

[0049] When the detent 3 is inserted from below into the first insertion chamber 261 of the detent, the locking section 531 passes over the temporary locking projection 241 and moves to an upper surface of the temporary locking projection 241, and the lower horizontal surface 5311 locks with the upper horizontal surface 2413. In this way, the detent 3 is held by the housing 2 (which is mounted in a temporary locking state) in a position in which the detent 3 is prevented from disengaging from the housing 2. At this point, the locking section 531 is housed in a temporary locking recess 243 formed between the temporary locking projection 241 and the final locking projection 242.

[0050] In the present embodiment, the temporary locking recess 243 has a vertical surface 2431 which adjoins the upper horizontal surface 2413, and the final locking projection 242 is formed at an upper end of the vertical surface 2431.

[0051] The final locking projection 242 has a lower inclined surface 2421 adjoining the upper end of the vertical surface 2431 and inclined inwards and upwards in the Y-direction (third direction: latitude direction), and a vertical surface 2422 adjoining an upper end of the lower inclined surface 2421. Furthermore, the final locking projection 242 has an upper inclined surface 2423 adjoining an upper end of the vertical surface 2422 and inclined outwards and upwards in the Y-direction (third direction: latitude direction).

[0052] A final locking recess 244 with a vertical surface 2441 is formed on an upper section of the final locking projection 242.

[0053] Therefore, in the present embodiment, when the detent 3, which is held in the temporary locked state by the housing 2, is pushed upwards, the locking section 531 is guided over the final locking projection 242 and moved to an upper side of the final locking projection 242, and the lower horizontal surface 5311 is locked to the upper inclined surface 2423. This holds the detent 3 in the final locked state by the housing 2. At this point, the locking section 531 is housed in the final locking recess 244, which is formed above the final locking projection 242.

[0054] In the present embodiment, the locking device 3 is held in the final locked position by the housing 2 by the lower horizontal surface 5311 of the locking section 531 engaging with the upper inclined surface 2423 of the final locking projection 242. Therefore, the locking device 3, held in the final locked position by the housing 2, can be pushed relatively easily into the temporary locked position.

[0055] When the locking device 3 is held in the temporary locking state by the housing 2, the lower horizontal surface 5311 of the locking section 531 is locked to the upper horizontal surface 2413 of the temporary locking projection 241. Therefore, in the present embodiment, the locking device 3, held in the temporary locking state by the housing 2, cannot easily detach from the housing 2. Based on the above, the housing 2 and the locking device 3 can be transported while the locking device 3 is held in the temporary locking state by the housing 2.

[0056] Furthermore, in the present embodiment, when the locking mechanism 3 is in the temporary locking position, the base section 4 is configured such that the connector 6 can be inserted into and removed from the cavity 25. When the locking mechanism 3 is in the final locking position, the base section 4 is configured to engage with the connector 6 located in the cavity 25 and regulates the separation of the connector 6 from the cavity 25.

[0057] In particular, the base end section 4 has a lower wall section 41 which is successively connected to the ends 5a on a lower side of the pair of side wall sections 5, and an intermediate wall 42 which is successively connected to a middle part of the lower wall section 41 in the Y direction (third direction: width direction) to project upwards.

[0058] In this embodiment, the base section 4 has the lower wall section 41, and the two side wall sections 5 are successively connected to the ends 41a on both sides of the lower wall section 41 in the Y-direction (third direction: width direction).

[0059] Furthermore, the partition wall 42 has a shape that corresponds to the shape of the concave section 2612 of the first insertion space of the detent 261, and when the detent 3 is in the final locking state, the partition wall 42 is inserted into the concave section 2612 (see Fig. 12) That is, the partition wall 42 has an upper wall section 421 that is narrower in the Y-direction (third direction: width direction), and a lower wall section 422 that connects to a lower end of the upper wall section 421 and has a greater width in the Y-direction (third direction: width direction) than the upper wall section 421. When the locking mechanism 3 is in its final locked position, the upper wall section 421 is inserted into the upper concave section 26121, and the lower wall section 422 is inserted into the lower concave section 26122.

[0060] Furthermore, in the present embodiment, a pair of cavity sections 43 are formed between the side wall sections 5 and the intermediate wall 42, and when the locking mechanism 3 is in the temporary locking state, the cavity sections 43 are in contact with the first cavity 251 (see Fig. 10) When the locking mechanism 3 is in its final locked position, the cavity sections 43 move upwards and are inserted into the wall sections 2611 of the first locking insertion chamber 261. At this point, an upper end of the lower wall section 41 engages with the engagement recess 61b in the first connector 6A, and the movement of the first connector 6A in the X-direction (first direction: front and rear direction) is also regulated by the upper end of the lower wall section 41.

[0061] Therefore, in the present embodiment, the upper end of the lower wall section 41 serves as the engagement section 41b of the connection of the locking device 3.

[0062] Furthermore, in the present embodiment, clearance-filling sections 511 are formed on the side wall sections 5 of the locking device 3. When the locking device 3 is in its final locked position, the clearance-filling sections 511 abut the housing 2, thereby suppressing any play in the locking device 3 in its final locked position.

[0063] In the present embodiment, each clearance-filling section 511 has a lower surface 5111 and an upper surface 5113, which are approximately horizontal and extend in the Y-direction (third direction: width direction), as well as an approximately vertical side surface 5112 for successive connection of the lower surface 5111 and the upper surface 5113. In this way, the clearance-filling sections 511 are formed on the side wall sections 5 such that they project outwards in the Y-direction (third direction). When the locking mechanism 3 is in its final locked position, the side surface 5112 of each clearance-filling section 511 is in surface contact with the vertical surface 2412 of the temporary locking projection 241.

[0064] To enable the locking section 531 to slide over the final locking projection 242 when the detent 3 is moved from the temporary locking position to the final locking position, as in the present embodiment, it is preferred that the side wall sections 5 deform elastically in the Y-direction (third direction: width direction). This makes it easier for the locking section 531 to slide over the final locking projection 242 and improves the sliding capability of the detent 3.

[0065] However, if the play of the detent 3 in the final locked position can be suppressed by the play-filling sections 511 bearing against the housing 2, as is the case in the present embodiment, the side wall sections 5 of the detent 3 may be bent due to the play-filling. In particular, when the detent 3 is pushed into the final locked position, the detent 3 is compressed by the housing 2 in the Y-direction (third direction: width direction), and there is a risk that the side wall sections 5 may be bent due to the compressive force. If the side wall sections 5 are then bent, the overlap tolerance of the lock between the housing 2 and the detent 3 is reduced, and the holding force between the housing 2 and the detent 3 in the final locked position may deteriorate.

[0066] In the present embodiment, the holding force between the locking device 3 and the housing 2 can therefore be ensured more reliably, whereby the play of the locking device 3 in the final locking state is suppressed.

[0067] In particular, the locking section 531 is configured such that at least a part of the locking section 531 is arranged on a part of the side wall section 5 that projects from the base section 4 in the X-direction (first direction). When the detent 3 is considered in the Y-direction (third direction), each clearance-filling section 511 is configured at a position that is spaced apart from the locking section 531 in the X-direction (first direction).

[0068] This means that the locking section 531 is formed on the side wall section 5 such that at least a part of the locking section 531 is present on a part of the side wall section 5 that is wider than the base section 4, with the part projecting beyond the base section 4. Then each clearance-filling section 511 is formed at a position spaced apart from the locking section 531 on the side wall section 5 in the X-direction (first direction).

[0069] In this way, a part on which the locking section 531 is formed outside the side wall section 5 in the Y direction (third direction), and a part on which each clearance-filling section 511 is formed, are completely spaced apart from each other in the X direction (first direction).

[0070] In this way, even if the locking device 3 is compressed by the housing 2 in the Y-direction when the locking device 3 is pushed into its final locking position, it is essentially possible to prevent the compressive force exerted on the locking device 3 from being transmitted to a part of the side wall section 5 in which the locking section 531 is formed. That is, even if the locking device 3 is compressed by the housing 2 in the Y-direction (third direction), it can be prevented that the compressive force exerted on the locking device 3 acts on the part of the side wall section 5 in which the locking section 531 is formed.

[0071] In this embodiment, it is thus possible to substantially prevent the bending deformation of the portion of the side wall section 5 in which the locking section 531 is formed, caused by the compressive force exerted on the detent 3 when the detent 3 is compressed by the housing 2. By substantially preventing the bending deformation of the portion of the side wall section 5 in which the locking section 531 is formed, a reduction in the overlap clearance (contact area) of the locking section 531 with the housing 2 can be prevented. Based on the above considerations, even when the clearance-filling section 511 rests against the housing 2 in the final locked state, it is possible to substantially prevent a reduction in the holding force between the detent 3 and the housing 2, thereby suppressing the play of the detent 3 in the final locked state.

[0072] In the present embodiment, as described above, the locking section 531 on the side wall section 5 is designed such that at least a part of the locking section 531 is present on a part of the side wall section 5 which is wider in the X direction (first direction) than the base section 4, with the part projecting from the base section 4.

[0073] Based on the above explanations, it is possible to suppress the reduction of a length W5 in the X-direction (first direction) of the locking section 531. The locking section 531 is designed in a position where it is influenced as little as possible by the pressure force generated in the detent 3, the pressure force being caused by the contact of the clearance-filling sections 511 of the side wall sections 5 with the housing 2.

[0074] In the present embodiment, the length W5 of the locking section 531 in the X-direction (first direction) is slightly longer than the length W3 of the base section 4 in the X-direction (first direction: front and rear directions). Furthermore, the sum of the length W5 of the locking section 531 in the X-direction (first direction) and a length W6 of the clearance-filling section 511 in the X-direction (first direction) is approximately equal to the length W4 of the side wall section 5 in the X-direction (first direction: front and rear directions).

[0075] In this way, the locking section 531 can be formed in a position where the locking section 531 is affected as little as possible by the pressure force generated in the detent 3 by the impact of the clearance-filling sections 511 of the side wall sections 5 on the housing 2, without reducing the length of the locking section 531 in the X-direction (first direction).

[0076] In this way, the reduction of the overlap clearance (contact area) due to the pressure force generated in the locking mechanism 3 can be suppressed as much as possible, while the overlap clearance (contact area) is relatively increased when the locking section 531 is locked to the housing 2 in the final locking state.

[0077] Therefore, when using the connector 1 according to the above embodiment, it is possible to ensure the holding force between the locking device 3 and the housing 2 more reliably, while suppressing the play of the locking device 3 in the final locking state.

[0078] Furthermore, in the present embodiment, the game filling sections 511 are formed at the ends 5a on one side (underside) in the Z direction (second direction: upward and downward direction) of the side wall sections 5.

[0079] In this way, the clearance-filling section 511 does not rest against the housing 2 when the detent 3 is held in the temporary locking position by the housing 2, and the clearance-filling section 511 rests against the housing 2 when the detent 3 is held in the final locking position by the housing 2. Because of this configuration, the compressive force exerted on the detent 3 by the clearance-filling section 511 resting against the housing 2 is prevented in most positions between the temporary locking position and the final locking position. This further improves the operability of the detent 3 when it is moved from the temporary locking position to the final locking position.

[0080] If the pressure force generated in the detent 3 in the temporary locking position is prevented, the deformation of the detent 3 in the temporary locking state is suppressed, and the reduction of the holding force between the detent 3 and the housing 2 can be prevented. Therefore, when carrying the housing 2, which holds the detent 3 in the temporary locking state, it can be more reliably prevented that the detent 3 disengages from the housing 2.

[0081] Furthermore, in the present embodiment, the clearance section 511 overlaps the base section 4 when the locking mechanism 3 is viewed in the Y-direction (third direction: width direction). In particular, when the locking mechanism 3 is viewed in the Y-direction (third direction: width direction), the entire clearance section 511 overlaps the lower wall section 41.

[0082] In this way, the base section 4 (lower wall section 41) can absorb the compressive force generated in the detent 3, which is caused by the contact of the clearance-filling section 511 with the housing 2 when the detent 3 is pushed into the final locking position. This makes it possible to more reliably suppress the deformation of the side wall sections 5 caused by the compressive force generated in the detent 3 and to more reliably ensure the holding force between the detent 3 and the housing 2 in the final locking state.

[0083] Furthermore, in the present embodiment, each side wall section 5 has a side wall body 51 which connects to the end 4a of the base section 4 in the Y direction (third direction: width direction), and a flexible arm 53 which connects to the side wall body 51 and can be bent and deformed in the Y direction (third direction: width direction).

[0084] In particular, the flexible arm 53 is connected to the side wall body 51 by a connecting wall 52. In the present embodiment, an upper end of the flexible arm 53 is successively connected to an upper end of the side wall body 51 by an upper connecting wall 521, and a lower end of the flexible arm 53 is successively connected to a lower end (end 51a) of the side wall body 51 by a lower connecting wall 522.

[0085] In this way, the flexible arm 53 is held in a doubly supported state by the side wall body 51, and the flexible arm 53 can be bent and deformed independently.

[0086] At this point, when the locking mechanism 3 is viewed in the Y-direction, the flexible arm 53 is continuously connected to the side wall body 51 in a state where at least part of the side wall body 51 is exposed, while at least part of the flexible arm 53 projects from the rear of the base section 4. That is, as in Fig. Figure 8 shows that when the locking mechanism 3 is viewed in the Y direction, part of an outer surface 51b of the side wall body 51 is exposed without being covered by the flexible arm 53.

[0087] The locking section 531 is formed on the flexible arm 53, which can be bent and deformed. In the present embodiment, the locking section 531 is formed on an arm surface 53a of the flexible arm 53, such that the locking section 531 projects outwards in the Y-direction (third direction: width direction). This makes it easier to perform the locking operation of the locking section 531 with the housing 2 or the unlocking operation between the locking section 531 and the housing 2.

[0088] Furthermore, the game filling section 511 is formed on a part of the side wall body 51 that is free from the flexible arm 53.

[0089] In this embodiment, the side wall body 51 is arranged separately from the flexible arm 53, on which the locking section 531 is formed, and the clearance-filling section 511 is formed on the side wall body 51. This makes it possible to increase the stiffness of the side wall body 51 while simultaneously ensuring the flexibility of the flexible arm 53. By increasing the stiffness of the side wall body 51, deformation of the side wall body 51 can be more reliably prevented when the side wall body 51 absorbs the compressive force generated in the locking mechanism 3, which is caused by the clearance-filling sections 511 striking the housing 2.Based on the above explanations, it is possible to prevent the displacement of the flexible arm 53, which is sequentially connected to the side wall body 51, and the flexible arm 53 is not significantly affected by the compressive force resulting from the gap-filling sections 511 coming into contact with the housing 2. In other words, it can be more reliably prevented that the flexible arm 53 bends and deforms inwards in the Y-direction (third direction: width direction), and the overlap clearance (contact area) of the locking section 531 with the housing 2 is reduced. This allows the holding force between the detent 3 and the housing 2 to be more reliably ensured in the final locking state.

[0090] Thus, the holding force between the locking device 3 and the housing 2 in the final locking state can be ensured more reliably, preventing a deterioration in the functionality of the locking device 3 when the locking section 531 is locked to the housing 2 or when the locking between the locking section 531 and the housing 2 is released. [Action / Effect]

[0091] The characteristic configuration of the connector in the above embodiment and the effects achieved thereby are described below.

[0092] The connector 1 shown in the embodiment above has a housing 2 configured such that the cavities 25, in which the connecting pieces 6 are housed, extend in the X-direction (first direction: front and back). Furthermore, the connector 1 has a locking element 3 inserted into the housing 2 from one side (bottom) in the Z-direction (second direction: up and down), which intersects the X-direction (first direction). The locking element 3 is mounted on the housing 2 in a state in which it can slide between a temporary locking position, in which it is temporarily locked to the housing 2, and a final locking position, in which it is permanently locked to the housing 2.

[0093] Furthermore, the locking mechanism 3 has the base section 4. When the locking mechanism 3 is in the temporary locking position, the base section 4 is configured to allow the connector 6 to be inserted into and removed from the cavity 25. When the locking mechanism 3 is in the final locking position, the base section 4 is configured to engage with the connector 6 located in the cavity 25 and regulates the separation of the connector 6 from the cavity 25. The locking mechanism 3 also has the side wall sections 5, which are sequentially connected to the ends 4a of the base section 4 in the Y-direction (third direction: width direction), intersecting the X-direction (first direction) and the Z-direction (second direction).

[0094] The length W4 of the side wall sections 5 in the X direction (first direction) is longer than the length W3 of the base section 4 in the X direction (first direction).

[0095] The side wall section 5 has the locking section 531, which faces the housing 2 in the Y direction (third direction) and is locked to the housing 2 when the detent 3 is in the final locking position. Furthermore, the side wall section 5 has the clearance-filling section 511, which projects outwards in the Y direction (third direction) and rests against the housing 2 when the detent 3 is in the final locking position.

[0096] Furthermore, the locking section 531 is designed such that at least a part of the locking section 531 is arranged on a part of the side wall section 5 that projects from the base section 4 in the X-direction (first direction). When the detent 3 is considered in the Y-direction (third direction), the clearance-filling section 511 is formed at a position that is spaced apart from the locking section 531 in the X-direction (first direction).

[0097] In this way, the locking element 3 of the connector 1 shown in the embodiment above has a side wall section 5 that is wider in plan view than the base section 4 in the X-direction (first direction). The locking section 531 is formed on the side wall section 5 such that at least a part of the locking section 531 is present on a portion of the side wall section 5 that is wider than the base section 4, with this portion projecting from the base section 4. Furthermore, the clearance-filling section 511 is formed at a position spaced apart from the locking section 531 on the side wall section 5 in the X-direction (first direction).

[0098] That is, in the connector 1 shown in the embodiment above, a part in which the locking section 531 is formed outside the side wall section 5 in the Y direction (third direction) and a part in which the clearance filling section 511 is formed are spaced apart from each other in the X direction (first direction).

[0099] In this way, even when the locking device 3 is compressed by the housing 2 in the Y-direction, it is essentially possible to prevent the compressive force exerted on the locking device 3 from being transmitted to a portion of the side wall section 5 in which the locking section 531 is formed when the locking device 3 is pushed into its final locking position. That is, even when the locking device 3 is compressed by the housing 2 in the Y-direction (third direction), it is possible to prevent the compressive force exerted on the locking device 3 from acting on the portion of the side wall section 5 in which the locking section 531 is formed. In this way, it is essentially possible to prevent bending deformation of the portion of the side wall section 5 in which the locking section 531 is formed, caused by the compressive force exerted on the locking device 3 when the locking device 3 is compressed by the housing 2.By substantially preventing the bending deformation of the part of the side wall section 5 in which the locking section 531 is formed, a reduction in the overlap clearance (contact area) of the locking section 531 with the housing 2 can be prevented.

[0100] As a result, even if the play-filling section 511 rests against the housing 2 in the final locking state to suppress play of the detent 3 in the final locking state, it is possible to essentially prevent the reduction of the holding force between the detent 3 and the housing 2.

[0101] Furthermore, in the connector 1 shown in the embodiment above, as described above, the locking section 531 is formed on the side wall section 5, such that at least a part of the locking section 531 is present on a part of the side wall section 5 which is wider in the X direction (first direction) than the base section 4, with the part projecting from the base section 4.

[0102] Based on the above explanations, it is possible to suppress the reduction in the length of the locking section 531 in the X-direction (first direction). The locking section 531 is formed in a position where it is affected as little as possible by the compressive force generated in the detent 3, which is caused by the contact of the clearance-filling section 511 of the side wall section 5 with the housing 2. That is, the locking section 531 can be formed in a position where it is affected as little as possible by the compressive force generated in the detent 3 by the contact of the clearance-filling section 511 of the side wall section 5 with the housing 2, without reducing the length of the locking section 531 in the X-direction (first direction).If the side wall section 5 has the same width as the base section 4, and the locking section 531 and the clearance-filling section 511 are positioned at spaced-apart locations, a reduction in the length of the locking section 531 in the X-direction (first direction) is unavoidable. However, if the side wall section 5 is wider in the X-direction (first direction) than the base section 4, as in the connector 1 shown in the embodiment above, it is possible to increase the length of the locking section 531 in the X-direction (first direction) more than if the side wall section 5 has the same width as the base section 4. This makes it possible to increase the contact area of ​​the locking section 531 with the housing 2.

[0103] In this way, when using the connector 1 according to the embodiment above, it is possible to essentially suppress the reduction of the overlap distance (contact area) due to the pressure force generated in the locking mechanism 3, while the overlap distance (contact area) is relatively increased when the locking section 531 is locked to the housing 2 in the final locking state.

[0104] Therefore, when using the connector 1 according to the above embodiment, it is possible to ensure the holding force between the locking device 3 and the housing 2 more reliably, while suppressing the play of the locking device 3 in the final locking state.

[0105] Furthermore, the game filling section 511 can be formed at the end 5a on one side (underside) in the Z direction (second direction: upward and downward direction) of the side wall section 5.

[0106] In this way, connector 1 can be realized in which, when the locking element 3 is held in the temporary locking position by the housing 2, the clearance-filling section 511 does not contact the housing 2, and when the locking element 3 is held in the final locking position by the housing 2, the clearance-filling section 511 does contact the housing 2. Due to this configuration, the compressive force exerted on the locking element 3, caused by the clearance-filling section 511 contacting the housing 2, can be prevented in most positions from the temporary locking position to the final locking position. This makes it possible to further improve the functionality of the locking element 3 when it is moved from the temporary locking position to the final locking position.

[0107] If the pressure force generated in the detent 3 in the temporary locking position is prevented, the deformation of the detent 3 in the temporary locking state is suppressed, and the reduction of the holding force between the detent 3 and the housing 2 can be prevented. Therefore, when carrying the housing 2, which holds the detent 3 in the temporary locking state, it can be more reliably prevented that the detent 3 disengages from the housing 2.

[0108] Furthermore, when considering the locking mechanism 3 in the Y direction (third direction: width direction), the game filling section 511 can be designed in such a way that it overlaps the base section 4.

[0109] In this way, the base section 4 can absorb the compressive force generated in the detent 3, which is caused by the contact of the clearance-filling section 511 with the housing 2 when the detent 3 is pushed into the final locking position. This allows the deformation of the side wall section 5 caused by the compressive force generated in the detent 3 to be suppressed more reliably, and the holding force between the detent 3 and the housing 2 to be ensured more reliably in the final locked state.

[0110] Furthermore, the side wall section 5 can have the side wall body 51, which is continuously connected to the end 4a of the base end section 4 in the Y direction (third direction: width direction), and the flexible arm 53, which is continuously connected to the side wall body 51 and which can be bent and deformed in the Y direction (third direction: width direction).

[0111] When the locking mechanism 3 is considered in the Y direction (third direction), the side wall body 51 and the flexible arm 53 can be shaped such that at least part of the side wall body 51 is exposed and at least part of the flexible arm 53 extends out of the base section 4 in the X direction (first direction).

[0112] The locking section 531 can be formed on the flexible arm 53, and the clearance-filling section 511 can be formed on a part that is free from the flexible arm 53 on the side wall body 51.

[0113] If the locking section 531 is formed on the flexible arm 53, it is thus possible to more easily perform an operation to lock the locking section 531 with the housing 2 or an operation to release the locking between the locking section 531 and the housing 2.

[0114] If the side wall body 51 is arranged separately from the flexible arm 53, on which the locking section 531 is formed, and the clearance-filling section 511 is formed on the side wall body 51, it is further possible to increase the stiffness of the side wall body 51 while simultaneously ensuring the flexibility of the flexible arm 53. Increasing the stiffness of the side wall body 51 more reliably prevents deformation of the side wall body 51 when it absorbs the compressive force generated in the locking mechanism 3 by the contact of the clearance-filling section 511 with the housing 2. This prevents displacement of the flexible arm 53, which is sequentially connected to the side wall body 51, and ensures that the flexible arm 53 is not significantly affected by the compressive force caused by the contact of the clearance-filling section 511 with the housing 2.In this way, it can be more reliably prevented that the flexible arm 53 bends and deforms inwards in the Y-direction (third direction: width direction), and the overlap clearance (contact area) of the locking section 531 with the housing 2 is reduced. This ensures a more reliable holding force between the detent 3 and the housing 2 in the final locking state.

[0115] Thus, the holding force between the locking device 3 and the housing 2 in the final locking state can be ensured more reliably, preventing a deterioration in the functionality of the locking device 3 when the locking section 531 is locked to the housing 2 or when the locking between the locking section 531 and the housing 2 is released. [Other]

[0116] Although the present embodiment has been described above, the present embodiment is not limited to the above description, and various modifications can be made within the framework of the basic features of the present embodiment.

[0117] The embodiment above shows an example in which the locking section 531 formed on the side wall section 5 (flexible arm 53) serves both as a final locking section and as a temporary locking section. However, it is also possible to arrange a temporary locking section separately from the locking section 531, which serves, for example, as a final locking section. In this case, it is advantageous to arrange the temporary locking section on the side wall section 5 (flexible arm 53).

[0118] Furthermore, the specifications (shape, size, layout, and the like) of the housing, connector, and other details can be modified accordingly.

[0119] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to this embodiment, and the configuration of the parts can be replaced by any configuration with a similar function, as long as it is within the scope of the claims.
