Description

Connector device

[0001] The present disclosure relates to a connector device.

[0002] Patent Document 1 discloses a floating connector including a slide housing to which contacts are attached and a base housing that holds the slide housing so as to be relatively displaceable in both the depth direction and the width direction. This floating connector can absorb misalignment in a two-dimensional direction orthogonal to the fitting direction during the fitting process with a mating connector.

[0003] Japanese Patent Application Laid-Open No. 2005-093424

[0004] When the above floating connector is fitted in a state where the mating connector is tilted, it is difficult to correct the tilt. As a countermeasure, for example, it is conceivable to support the entire floating connector so as to be swingable about an axis intersecting the fitting direction.

[0005] However, when the floating connector is supported so as to be swingable, the floating connector may wait in a tilted posture in the state before fitting due to the weight of the wire harness led out from the slide housing or the elastic restoring force of the wire harness when the wire harness is bent and routed. In this case, when the mating connector tilts in a direction away from the floating connector in a direction intersecting the fitting direction, there is a risk that the fitting may not be possible. In order to enable fitting even when the floating connector and the mating connector are tilted so as to be separated from each other, it is necessary to increase the guiding portion of the mating connector so that the floating connector can be guided inside the mating connector even when they are tilted so as to be separated from each other.

[0006] The connector device of the present disclosure has been completed based on the above circumstances, and aims to enable smooth fitting with a mating connector whose posture is tilted while suppressing an increase in size.

[0007] The connector device of the present disclosure comprises a movable member that can be mated with a mating connector, and a support member that pivotably supports the movable member, wherein the support member has a support hole and a locking portion, and the movable member has a shaft portion mounted so as to be rotatable relative to the support hole, and a locking portion that holds the movable member in a neutral position by engaging with the locking portion, wherein the locking portion is held in a state of being engaged with the locking portion by the elasticity of an elastic retaining piece, and when the movable member receives a pressing force from the mating connector, the elastic retaining piece elastically deforms so as to disengage the locking portion from the locking portion.

[0008] In this disclosure, the neutral position is defined as "a position that a movable member can take within its swingable range, excluding the position in which it is positioned at the end of the swingable range."

[0009] According to this disclosure, it is possible to suppress an increase in size while enabling smooth mating with a mating connector that is tilted.

[0011] [Description of Embodiments of the Disclosure] Embodiments of the Disclosure will be listed and described first. Any combination of the following embodiments, to the extent that they do not cause inconsistencies, is also included as an embodiment for carrying out the invention. The connector device of the Disclosure comprises: (1) a movable member that can be mated with a mating connector, and a support member that pivotably supports the movable member. The support member has a support hole and a locking portion formed therein. The movable member has a shaft portion mounted so as to be rotatable relative to the support hole, and a locking portion that holds the movable member in a neutral position by engaging with the locking portion. The locking portion is held in a state of being engaged with the locking portion by the elasticity of an elastic retaining piece. When the movable member receives a pressing force from the mating connector, the elastic retaining piece elastically deforms so as to disengage the locking portion from the locking portion.

[0012] In this disclosure, the neutral position is defined as "a position that a movable member can take within its swingable range, excluding the position in which it is positioned at the end of the swingable range."

[0013] According to the configuration of this disclosure, the movable member can be held in a neutral position by the locking of the locking portion and the locking portion before mating with the mating connector. By holding the movable member in a neutral position, it is possible to prevent the mating connector and the movable member from tilting their positions in a direction that separates them from each other in a direction intersecting the mating direction. This suppresses the need to enlarge the part required to correct the orientation of the tilted mating connector so that it can be mated with the movable member. When the tilted mating connector presses against the movable member, the elastic retaining piece elastically deforms, causing the locking portion to separate from the locking portion. As a result, the movable member is released from the state in which it was held in a neutral position, and the movable member swings in accordance with the tilt of the mating connector and mates with the mating connector. According to this disclosure, it is possible to enable smooth mating with a tilted mating connector while suppressing an increase in size.

[0014] (2) In (1), it is preferable that the locking portion is formed on the inner circumferential surface of the support hole and the locking portion is formed on the outer circumferential surface of the shaft portion. With this configuration, it is possible to simplify the shapes of the support member and the movable member compared to the case in which the locking portion is placed outside the support hole and the locking portion is placed on a part other than the outer circumferential surface of the shaft portion.

[0015] (3) In (1) or (2), it is preferable that the elastic retaining piece is positioned between the inner circumferential surface of the support hole and the outer circumferential surface of the shaft portion. With this configuration, since the elastic retaining piece is positioned within the opening area of ​​the support hole, it is possible to provide the elastic retaining piece while suppressing an increase in the size of the connector device compared to the case where the elastic retaining piece is positioned outside the support hole.

[0016] (4) In (3), the shaft portion is provided with an elastically deformable elastic retaining piece, and the elastic retaining piece locks onto the opening edge of the support hole in an elastically returned state, thereby holding the shaft portion in a state where it cannot be removed from the support hole, and it is preferable that the elastic retaining piece is integrally formed with the shaft portion. With this configuration, since the elastic retaining piece is integrally formed with the shaft portion, which is a common part with the elastic retaining piece, the material of the support member can be made to have higher rigidity than the shaft portion.

[0017] (5) In (1) or (2), it is preferable that the region of the inner circumferential surface of the support hole that faces the direction perpendicular to the fitting direction between the mating connector and the movable member functions as a stopper that restricts the rotation of the shaft. With this configuration, the swing range of the movable member can be defined by the stopper.

[0018] [Details of Embodiments of the Disclosure] [Example 1] An embodiment 10 of the present disclosure will be described with reference to Figures 1 to 9. The present invention is not limited to these examples and is shown by the claims, including all modifications within the meaning and scope of the equivalents of the claims. In this embodiment 1, the front-to-back direction is defined as the F direction in Figures 1 to 7. The up-and-down direction is defined as the H direction in Figures 1 to 9. The left-to-right direction is defined as the R direction in Figures 1 to 5, 8, and 9.

[0019] The connector device 10 of this embodiment 1 is, for example, a device attached to the chassis of an automobile (not shown). The connector device 10 is a device that is fitted from below to a mating connector 60 attached to the body of an automobile (not shown). On the surface (bottom surface) of the mating connector 60 facing the connector device 10, a guide portion 61 is formed that protrudes toward the connector device 10. When the connector device 10 and the mating connector 60 are fitted with a misalignment in a two-dimensional direction (horizontal direction) perpendicular to the fitting direction, the guide portion 61 slides against the connector device 10, thereby correcting the misalignment in the two-dimensional direction (front-rear direction and left-right direction) between the connector device 10 and the mating connector 60.

[0020] The connector device 10 includes a movable member 11 and a support member 50. The movable member 11 is composed of a housing 12 into which the mating connector 60 is fitted, a holder 20 that holds the housing 12, and a bracket 30 that supports the holder 20. The housing 12 has a terminal holding portion 13 that holds terminal fittings (not shown) and a rectangular tubular fitting portion 14 that extends upward from the terminal holding portion 13. A pair of protruding guide portions 15 are formed on both the left and right outer surfaces of the housing 12.

[0021] The holder 20 has a front wall portion 21 whose thickness direction is oriented in the front-rear direction, and a pair of symmetrical side wall portions 22 that extend cantilevered rearward from both left and right side edges of the front wall portion 21. Guide grooves 23 extending in the front-rear direction are formed on the inner surfaces of the left and right side wall portions 22. The housing 12 is supported so that the guided portion 15 can be accommodated in the guide grooves 23, thereby allowing relative displacement in the horizontal direction (front-rear direction and left-right direction) with respect to the holder 20.

[0022] A first shaft portion 24 is formed on the outer surfaces of the left and right side wall portions 22, with its axis oriented in the left-right direction. The first shaft portion 24 is cylindrical in shape with its axis oriented in the left-right direction. A first locking portion 25 is formed on the upper surface of the first shaft portion 24, with the outer surface of the first shaft portion 24 recessed. A locking projection 26 is formed on the outer surfaces of the left and right side wall portions 22 at a position in front of the first shaft portion 24.

[0023] The bracket 30 is a single component having a plate-shaped base portion 31 with its thickness direction oriented in the front-rear direction, and a pair of plate-shaped arm portions 32 that extend cantilevered backward from both left and right edges of the plate-shaped base portion 31. Both the left and right plate-shaped arm portions 32 have first support holes 33 that penetrate the plate-shaped arm portions 32 in the left-right direction. The first support holes 33 are elongated oval in the vertical direction. A first lock portion 34 that protrudes downward is formed at the upper end of the inner circumferential surface of the first support hole 33.

[0024] A first elastic retaining piece 35 is formed in front of the first support hole 33 on both the left and right plate-shaped arm portions 32. The first elastic retaining piece 35 is thinner than the area of ​​the plate-shaped arm portion 32 on which the first elastic retaining piece 35 is not formed, and is capable of elastic deformation in the left-right direction. The inner surface of the first elastic retaining piece 35 is continuous and flush with the area of ​​the inner surface of the plate-shaped arm portion 32 on which the first elastic retaining piece 35 is not formed. A retaining projection 36 is formed on the inner surface of the first elastic retaining piece 35.

[0025] The holder 20 is attached to the bracket 30 by fitting the first shaft portion 24 into the first support hole 33. During attachment, the pair of plate-shaped arm portions 32 are elastically deformed to expand. With the first shaft portion 24 fitted into the first support hole 33, the holder 20 is moved upward relative to the bracket 30, and the locking projection 26 of the holder 20 is locked onto the retaining projection 36 of the first elastic retaining piece 35 from above. By moving the holder 20 upward, the first locking portion 25 of the first shaft portion 24 fits into the first locking portion 34 of the first support hole 33, and the rotation of the first shaft portion 24 within the first support hole 33 is restricted.

[0026] The holder 20 is held in a first neutral position relative to the bracket 30 by restricting the rotation of the first shaft portion 24 relative to the bracket 30. The first neutral position of the holder 20 is a position that the movable member 11 can take within the swingable range of the movable member 11 centered on the first shaft portion 24, excluding the state in which it is positioned at both ends of the swingable range. For example, the first neutral position may be set to a position in which the movable member 11 is positioned in the middle of the swingable range of the movable member 11 centered on the first shaft portion 24. Alternatively, for example, the first neutral position may be set to a position in which the movable member 11 can be fitted without swinging around the first shaft portion 24, assuming that the mating connector 60 is to be fitted close to the connector device 10 without misalignment or tilting. In other words, the first neutral position may be a position in which the movable member 11 can be fitted with the mating connector 60 without the movable member 11 moving parallel to the front-rear direction which is perpendicular to both the fitting direction (up-down direction) between the mating connector 60 and the connector device 10 and the axial direction (left-right direction) of the first shaft portion 24. For example, the first position holding portion 37 is composed of the first shaft portion 24, the first locking portion 25, the locking projection 26, the first support hole 33, the first locking portion 34, and the first elastic holding piece 35.

[0027] A mounting portion 40 is integrally formed on the front surface of the plate-shaped base portion 31. The mounting portion 40 has a second shaft portion 41, an elastic pressing portion 42, a pair of elastic retaining pieces 43, and a pair of second elastic retaining pieces 44. The second shaft portion 41 is a plate-shaped portion with its thickness direction oriented in the left-right direction. The upper end of the second shaft portion 41 functions as a second locking portion 45. The elastic pressing portion 42 is a portion that extends radially diagonally forward from the rear end of the second shaft portion 41. The pair of elastic retaining pieces 43 are portions that extend cantilevered diagonally backward from the front end of the second shaft portion 41. The elastic retaining pieces 43 are designed to be elastically deformable in the left-right direction. The pair of second elastic retaining pieces 44 are portions that extend cantilevered downward from the lower ends of the left and right outer surfaces of the second shaft portion 41. The second elastic retaining pieces 44 are designed to be elastically deformable in the up-down direction.

[0028] The support member 50 is a panel-shaped member with its thickness direction oriented in the front-rear direction. The support member 50 is fixed to the chassis of an automobile (not shown). The support member 50 has a second support hole 51 formed therein, which penetrates the support member 50 in the front-rear direction. The second support hole 51 is an elongated oval shape in the vertical direction. A second locking portion 52 is formed on the inner circumferential surface of the second support hole 51. For example, the second locking portion 52 is formed in a shape in which the upper end of the inner circumferential surface of the second support hole 51 is recessed upward. The left and right side edges 51S of the inner circumferential edge of the second support hole 51 function as stoppers 53. The left and right side edges 51S correspond to the regions of the inner circumferential surface of the second support hole 51 that face each other in an intersecting direction perpendicular to the fitting direction between the mating connector 60 and the movable member 11. The stoppers 53 define the maximum swing angle of the movable member 11 when the movable member 11 swings left and right relative to the support member 50.

[0029] The bracket 30 is attached to the support member 50 by fitting the second shaft portion 41 into the second support hole 51. During attachment, the attachment portion 40 is passed through the second support hole 51 while elastically deforming the pair of elastic retaining pieces 43. With the attachment portion 40 attached to the second support hole 51, the elastic pressing portion 42 elastically presses the rear surface of the support member 50, and the pair of elastic retaining pieces 43 lock onto the front surface of the support member 50. In addition, the pair of second elastic retaining pieces 44 elastically press the lower end of the inner circumferential surface of the second support hole 51, thereby pressing the bracket 30 upward relative to the support member 50. This pressing action causes the second locking portion 45 of the bracket 30 to fit into the second lock portion 52 of the support member 50, restricting the relative rotation of the bracket 30 with respect to the support member 50.

[0030] The bracket 30 is held in a second neutral position relative to the support member 50 by restricting the rotation of the second shaft portion 41 with respect to the support member 50. The second neutral position of the bracket 30 is a position that the movable member 11 can take within the swingable range of the movable member 11 centered on the second shaft portion 41, excluding the state in which it is positioned at both ends of the swingable range. For example, the second neutral position may be set to a position in which the movable member 11 is positioned in the middle of the swingable range of the movable member 11 centered on the second shaft portion 41. Alternatively, for example, the second neutral position may be set to a position in which the movable member 11 can be fitted without swinging around the second shaft portion 41, assuming that the mating connector 60 is to be fitted close to the connector device 10 without misalignment or tilting. In other words, the second neutral position may be a position in which the movable member 11 can be fitted with the mating connector 60 without the movable member 11 moving in a left-right direction perpendicular to both the fitting direction (up-down direction) between the mating connector 60 and the connector device 10 and the axial direction (front-back direction) of the second shaft portion 41. For example, the second position holding portion 57 is composed of the second shaft portion 41, the second locking portion 45, the second elastic retaining piece 44, the second support hole 51, and the second locking portion 52.

[0031] As shown in Figure 6, in a side view of the connector device 10, when the mating connector 60 approaches the movable member 11 from above in an oblique position, the mating connector 60 interferes with the fitting portion 14 of the housing 12, causing the movable member 11 to change its orientation to match that of the mating connector 60. At this time, in addition to the pressing force in the front-rear direction, a downward pressing force also acts on the housing 12. This downward pressing force causes the locking projection 26 of the holder 20 to disengage from the holding projection 36 while elastically deforming the first elastic holding piece 35 of the bracket 30, and the movable member 11 (housing 12 and holder 20) is displaced downward relative to the bracket 30.

[0032] This relative downward displacement of the movable member 11 causes the first locking portion 25 of the first shaft portion 24 to disengage from the first locking portion 34 of the bracket 30, releasing the movable member 11 from its first neutral position and allowing it to rotate relative to the bracket 30. From this state, as the mating with the mating connector 60 progresses, as shown in Figure 7, the movable member 11 swings with the first shaft portion 24 as a pivot point in accordance with the tilt of the mating connector 60, and the housing 12 mates with the mating connector 60.

[0033] As shown in Figure 8, in a front view of the connector device 10, when the mating connector 60 approaches the movable member 11 from above in an oblique position, the mating connector 60 interferes with the fitting portion 14 of the housing 12, causing the movable member 11 to change its orientation to match that of the mating connector 60. At this time, in addition to the pressing force in the left-right direction, a downward pressing force also acts on the housing 12. Due to this downward pressing force, the bracket 30 is displaced downward relative to the support member 50, while the second elastic retaining piece 44 is elastically deformed.

[0034] The relative downward displacement of the bracket 30 causes the second locking portion 45 of the second shaft portion 41 to separate from the second locking portion 52 of the support member 50, releasing the bracket 30 from its second neutral position and allowing the bracket 30 and the movable member 11 to rotate relative to the support member 50. From this state, as the mating with the mating connector 60 progresses, as shown in Figure 9, the bracket 30 and the movable member 11 swing around the second shaft portion 41 as a pivot point in accordance with the inclination of the mating connector 60, and the housing 12 engages with the mating connector 60. When the second shaft portion 41 comes into contact with the stopper 53 during the swinging of the movable member 11 in the left-right direction, further swinging of the movable member 11 is restricted.

[0035] The connector device 10 of this embodiment 1 includes a movable member 11 that can be mated with a mating connector 60, and a support member 50 that pivotably supports the movable member 11. The support member 50 has a second support hole 51 and a second locking portion 52. The movable member 11 has a second shaft portion 41 and a second locking portion 45. The second shaft portion 41 is mounted so as to be able to rotate relative to the second support hole 51. The second locking portion 45 holds the movable member 11 in a second neutral position by locking with the second locking portion 52. The second locking portion 45 is held in a state of being locked with the second locking portion 52 by the elasticity of the second elastic retaining piece 44. When the movable member 11 receives a pressing force from the mating connector 60, the second elastic retaining piece 44 elastically deforms so as to separate the second locking portion 45 from the second locking portion 52. In this embodiment 1, the second neutral position is defined as "a position that the movable member 11 can take within its swingable range, excluding the state in which it is positioned at the end of the swingable range."

[0036] In the connector device 10 of this embodiment, the movable member 11 can be held in a second neutral position by the locking of the second locking portion 52 and the second locking portion 45 before mating with the mating connector 60. By holding the movable member 11 in the second neutral position, it is possible to prevent the mating connector 60 and the movable member 11 from tilting their positions in a direction that separates them from each other in a direction intersecting the mating direction. This prevents the need to enlarge the part required to correct the orientation of the tilted mating connector 60 so that it can be mated with the movable member 11. When the tilted mating connector 60 presses against the movable member 11, the second elastic retaining piece 44 elastically deforms, causing the second locking portion 45 to disengage from the second locking portion 52. As a result, the movable member 11 is released from the state in which it was held in the second neutral position, and the movable member 11 swings in accordance with the tilt of the mating connector 60 and mates with the mating connector 60. According to the connector device 10 of this embodiment 1, it is possible to suppress an increase in size while enabling smooth mating with the mating connector 60, which is tilted.

[0037] Furthermore, if the neutral position is the position of the movable member 11 that allows the mating operation with the mating connector 60 to be completed without displacement in a two-dimensional direction perpendicular to the mating direction with the mating connector 60, it is easier to avoid a situation where the mating connector 60 and the movable member 11 tilt their positions in a direction that separates them from each other in a direction that intersects the mating direction. Therefore, it is possible to further suppress the enlargement of the part used to correct the orientation of the diagonally positioned mating connector 60 so that it can be mated with the movable member 11. Note that the form in which "the movable member 11 is displaced in a direction intersects the mating direction" includes a form in which the movable member 11 swings relative to the support member 50 in a direction intersects the mating direction, and a form in which the movable member 11 moves parallel to the support member 50 in a two-dimensional direction perpendicular to the mating direction.

[0038] The second locking portion 52 is formed on the inner circumferential surface of the second support hole 51. The second locking portion 45 is formed on the outer circumferential surface of the second shaft portion 41. With this configuration, the shapes of the support member 50 and the movable member 11 can be simplified compared to the case where the second locking portion 52 is placed outside the second support hole 51 and the second locking portion 45 is placed on a part other than the outer circumferential surface of the second shaft portion 41.

[0039] The second elastic retaining piece 44 is positioned between the inner circumferential surface of the second support hole 51 and the outer circumferential surface of the second shaft portion 41. With this configuration, since the second elastic retaining piece 44 is positioned within the opening area of ​​the second support hole 51, it is possible to provide the elastic retaining piece 44 while suppressing an increase in the size of the connector device 10, compared to the case where the second elastic retaining piece 44 is positioned outside the second support hole 51.

[0040] An elastically deformable elastic retaining piece 43 is formed on the second shaft portion 41. The elastic retaining piece 43 locks the second shaft portion 41 in a state where it is not dislodged from the second support hole 51 by being elastically returned to its original position and engaging with the opening edge of the second support hole 51. The second elastic retaining piece 44 is integrally formed with the second shaft portion 41. With this configuration, since the second elastic retaining piece 44 is integrally formed with the second shaft portion 41, which is a common part with the elastic retaining piece 43, the material of the support member 50 can be made to be more rigid than that of the second shaft portion 41.

[0041] Of the inner circumferential surface of the second support hole 51, the left and right pair of side edges 51S, which are regions facing the intersecting direction (left-right direction) perpendicular to the fitting direction (up-down direction) between the mating connector 60 and the movable member 11, function as stoppers 53 that restrict the rotation of the second shaft portion 41. With this configuration, the swing range of the movable member 11 can be defined by the stoppers 53.
