Embodiments for Carrying Out the Invention

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure is [1] A housing, a bus bar partially embedded in the housing to which a mating terminal is connected, a nut holding member attached to the housing, and a nut held by the nut holding member, wherein the bus bar has a terminal connection portion extending outside the housing, the terminal connection portion has a through hole into which a fastening bolt screwed to the nut is inserted, the mating terminal is fastened by the bolt and the nut, and the nut holding member has a restricting portion for restricting rotation of the mating terminal about the axis of the through hole.

[0011] According to this configuration, the restricting portion for restricting rotation of the mating terminal is provided on a nut holding member separate from the housing. Therefore, it is possible to set the position of the restricting portion regardless of the molding constraints of the housing. Thus, it is possible to improve the design freedom of the connector.

[0012] [2] The terminal connection portion has an extending portion extending from the housing along a first direction, and a portion to be fastened extending from the tip of the extending portion in a second direction intersecting the first direction, the portion to be fastened has the through hole, and is fastened to the mating terminal by the bolt and the nut, the housing has an opposing portion opposing the portion to be fastened in a direction along the axis of the through hole, and the nut holding member and the nut are provided between the portion to be fastened and the opposing portion.

[0013] According to this configuration, in a connector in which the terminal connection portion of the bus bar is bent, a restricting portion can be provided on the nut holding member attached between the portion to be fastened of the terminal connection portion and the opposing portion of the housing.

[0014] [3] The restricting portion is provided near the tip in the second direction with respect to the portion to be fastened. According to this configuration, when performing insert molding in which the bus bar is an insert part and the housing is injection molded, a slide mold may be arranged to create a space for arranging a nut between the fastened part of the bus bar and the opposing part of the housing. When the ejection direction of this slide mold is along the second direction, a restricting part extending from the housing cannot be set near the tip of the fastened part in the second direction. Therefore, by setting the restricting part provided on the nut holding member near the tip of the fastened part in the second direction, it becomes possible to set the restricting part at a position where it cannot be provided on the housing.

[0015] [4] The housing has insulating walls provided on both sides of the fastened part in a third direction perpendicular to both the first direction and the second direction. According to this configuration, not only the restricting part of the nut holding member but also the insulating walls of the housing can restrict the rotation of the mating terminal. That is, by providing a plurality of parts that restrict the rotation of the mating terminal, it becomes possible to prepare a plurality of position settings of the mating terminal in the circumferential direction.

[0016] [5] The housing has a base end side restricting part provided near the base end of the fastened part in the second direction. According to this configuration, at least four of the restricting part of the nut holding member, a pair of insulating walls, and the base end side restricting part are provided in the connector as parts that restrict the rotation of the mating terminal. As a result, by providing a plurality of parts that restrict the rotation of the mating terminal, it becomes possible to prepare at least four position settings of the mating terminal in the circumferential direction.

[0017] [6] The restricting part has a columnar shape extending along the axis of the through hole. According to this configuration, it becomes possible to suitably restrict the rotation of the mating terminal by the columnar restricting part.

[0018] [Details of the Embodiment of the Present Disclosure] A specific example of the connector of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be exaggerated or simplified. Also, the dimensional ratios of each part may differ in each drawing. Further, in this specification, "vertical" and "orthogonal" include not only the cases of strict verticality and orthogonality, but also the cases of substantially vertical and orthogonal within the range where the actions and effects in the present embodiment are achieved.

[0019] In addition, in this specification, "opposite" means that surfaces or members are in a front-to-front position with respect to each other, and includes not only the case where they are completely in a front-to-front position, but also the case where they are partially in a front-to-front position. Further, in this specification, "opposite" includes both the case where a member different from the two parts is interposed between the two parts and the case where nothing is interposed between the two parts.

[0020] (Overall configuration of connector 10) As shown in FIG. 1, the connector 10 of the present embodiment includes a housing 11, a bus bar 12, a nut holding member 13, and a nut 14. The housing 11 is made of an insulator such as synthetic resin, for example. One part of the bus bar 12 is embedded in the housing 11.

[0021] The housing 11 is attached to, for example, a device case (not shown). The device-side connection portion 15 provided at one end of the bus bar 12 is electrically connected to the internal components of the device case. The bus bar 12 has a terminal connection portion 16 at the end opposite to the device-side connection portion 15.

[0022] As shown in FIG. 3, the terminal connection portion 16 is connected to the mating terminal 17. The mating terminal 17 is connected to the end portion of an electric wire 18 that is electrically connected to an electric component (not shown). The mating terminal 17 has a connection portion 17a that is connected to the terminal connection portion 16 of the bus bar 12 and a barrel portion 17b to which the end portion of the electric wire 18 is fixed. The connection portion 17a has a bolt fastening hole (not shown) through which a bolt B is inserted. The connection portion 17a is fastened to the terminal connection portion 16 by the bolt B and the nut 14. The barrel portion 17b is connected to the end portion of the electric wire 18 by, for example, crimping. That is, the mating terminal 17 is a round terminal having a barrel portion 17b as a crimping portion and a bolt fastening hole, and is formed by press working from a plate-like material.

[0023] (Configuration of the bus bar 12) As shown in FIGS. 1 and 2, the bus bar 12 is made of a conductive material such as metal. The bus bar 12 is, for example, in a plate shape. The bus bar 12 is formed by press working from a plate-like material, for example.

[0024] Each of the terminal connection portion 16 and the device-side connection portion 15 in the bus bar 12 extends outside the housing 11. That is, the terminal connection portion 16 and the device-side connection portion 15 are not portions embedded inside the housing 11.

[0025] In the drawing, the X direction, the Y direction, and the Z direction indicate three directions that are orthogonal to each other. A plurality of bus bars 12 are arranged in parallel along the X direction, for example. In the bus bar 12, the terminal connection portion 16 extends from the housing 11 to one side in the Y direction, and the device-side connection portion 15 extends from the housing 11 to the other side in the Y direction.

[0026] The terminal connection portion 16 has an extension portion 21 extending along the Y direction from the housing 11, and a fastened portion 22 extending in a direction intersecting the Y direction from the tip of the extension portion 21. That is, the terminal connection portion 16 has a shape that bends from the extension portion 21 to the fastened portion 22. The extension portion 21 has, for example, a plate shape perpendicular to the Z direction. The fastened portion 22 has, for example, a plate shape perpendicular to the Y direction. The fastened portion 22 extends along the Z direction from the tip of the extension portion 21. That is, the angle formed by the extension portion 21 and the fastened portion 22 is approximately a right angle.

[0027] The fastened portion 22 has a through hole 23 through which the bolt B shown in FIG. 3 is inserted. The through hole 23 penetrates the fastened portion 22 along the Y direction. That is, the axis L1 of the through hole 23 is along the Y direction. The shape of the through hole 23 as viewed from the penetrating direction is, for example, circular.

[0028] (Configuration of the housing 11) As shown in FIGS. 2, 4, and 5, the housing 11 has a facing portion 31 facing the fastened portion 22 in the direction along the axis L1. The nut holding member 13 and the nut 14 are provided between the fastened portion 22 and the facing portion 31.

[0029] The housing 11 includes a base portion 32, an insulating wall 33 extending from the base portion 32, and a proximal end side regulating portion 34 extending from the base portion 32. A part of the bus bar 12 is embedded in the base portion 32. The base portion 32 is a portion of the housing 11 that includes the facing portion 31. Note that a plurality of the facing portions 31, a pair of insulating walls 33, and proximal end side regulating portions 34 are provided corresponding to a plurality of bus bars 12, respectively.

[0030] The insulating wall 33 is a wall for ensuring insulation around the terminal connection portion 16. The insulating wall 33 is provided, for example, on both sides in the X direction of each terminal connection portion 16. The insulating wall 33 protrudes, for example, along the Y direction from the base portion 32. The insulating wall 33 has, for example, a plate shape perpendicular to the X direction. That is, as shown in FIG. 3, when viewed from the Y direction, the insulating wall 33 has a shape extending linearly along the Z direction.

[0031] The proximal-end side restricting portion 34 is provided near the proximal end 22a in the Z direction with respect to the fastened portion 22. The proximal end 22a in the Z direction of the fastened portion 22 is the end portion on the side where it is connected to the extending portion 21 in the fastened portion 22. Also, the distal end 22b of the fastened portion 22 is the end portion on the side opposite to the proximal end 22a in the Z direction. The proximal-end side restricting portion 34 faces the proximal end 22a of the fastened portion 22 in the Z direction. In the following description, the direction in which the distal end 22b of the fastened portion 22 faces in the Z direction may be referred to as the downward or lower side, and the opposite direction may be referred to as the upward or upper side.

[0032] The proximal-end side restricting portion 34 has, for example, a columnar shape extending along the Y direction from the base portion 32. The proximal-end side restricting portion 34 faces the proximal end 22a of the fastened portion 22 in the Z direction. The proximal-end side restricting portion 34 restricts the rotation of the mating terminal 17 about the axis L1. As shown in FIG. 3, the proximal-end side restricting portion 34 is provided at a position overlapping the center line L2 between the insulating walls 33 on both sides of the terminal connection portion 16 when viewed from the Y direction. The center line L2 is a straight line extending along the Z direction. Also, the center line L2 intersects the axis L1 of the through hole 23. In the X direction, the distances from the center line L2 to the insulating walls 33 on both sides thereof are equal to each other.

[0033] As shown in FIG. 4, the insulating wall 33 is configured to face the fastened portion 22 and the connection portion 17a of the mating terminal 17 fixed to the fastened portion 22 in the X direction. Also, the proximal-end side restricting portion 34 is configured to face the fastened portion 22 and the connection portion 17a in the Z direction.

[0034] (Configuration of the nut holding member 13) As shown in FIG. 2, the nut holding member 13 is separate from the housing 11. The nut holding member 13 is attached to the housing 11. Note that a plurality of nut holding members 13 are provided corresponding to the plurality of busbars 12 respectively. The nut holding member 13 has a holding portion main body 41 that holds the nut 14, an extension portion 42, a regulating portion 43, and a pair of fixing portions 44.

[0035] The holding portion main body 41 has a nut accommodating portion 41a. The nut 14 is accommodated in the nut accommodating portion 41a. The nut 14 and the nut accommodating portion 41a form a polygon such as a square when viewed from the Y direction. The nut 14 is fixed to the nut accommodating portion 41a by, for example, press-fitting.

[0036] The fixing portions 44 are provided on both sides of the holding portion main body 41 in the X direction respectively. Each fixing portion 44 has a protruding portion 45 that protrudes from the side surface 41b of the holding portion main body 41 in the X direction, an arm portion 46 that extends along the Z direction from the protruding portion 45, and a locking portion 47 provided at the tip of the arm portion 46.

[0037] The nut holding member 13 is assembled to the housing 11 along the Z direction from below. In a state where the nut holding member 13 is assembled to the housing 11, the insulating wall 33 is located between the side surface 41b of the holding portion main body 41 and the arm portion 46. The locking portion 47 is locked to a notch portion 33a formed at the Z-direction end of the insulating wall 33. Thereby, the nut holding member 13 is held so as not to drop off from the housing 11 in the Z direction.

[0038] As shown in FIG. 5, in a state where the nut holding member 13 is assembled to the housing 11, the nut 14 accommodated in the nut accommodating portion 41a is in contact with the back surface of the fastened portion 22. The nut 14 is arranged such that the central axis of the nut 14 coincides with the axis L1 of the through hole 23. Further, for example, the holding portion main body 41 of the nut holding member 13 has a first contact portion 41c that contacts the housing 11 in the Z direction and a second contact portion 41d that contacts the extending portion 21 of the terminal connection portion 16 in the Z direction. Further, the holding portion main body 41 has a hole 41e into which the tip of the bolt B protruding from the nut 14 enters.

[0039] As shown in FIG. 4, a guide portion 31a protruding in the Y direction is provided on the opposing portion 31 of the housing 11. The guide portion 31a extends linearly along the Z direction. A groove 48 into which the guide portion 31a fits is formed linearly along the Z direction on the back surface of the holding portion main body 41. By the engagement between the guide portion 31a and the groove 48, the positioning of the nut holding member 13 with respect to the housing 11 in the X direction is achieved.

[0040] As shown in FIGS. 1, 2, and 5, the extension portion 42 extends downward from the holding portion main body 41. The restricting portion 43 extends from the extension portion 42 along the Y direction to the same side as the terminal connection portion 16. The restricting portion 43 has, for example, a columnar shape extending in the Y direction. The restricting portion 43 is provided near the tip 22b in the Z direction with respect to the fastened portion 22. That is, the restricting portion 43 faces the tip 22b of the fastened portion 22 in the Z direction. Further, the restricting portion 43 is configured to face the connection portion 17a of the mating terminal 17 fixed to the fastened portion 22 in the Z direction.

[0041] As shown in FIG. 3, the restricting portion 43 is provided at a position overlapping the center line L2 between the pair of insulating walls 33 when viewed from the Y direction. That is, the positions of the restricting portion 43, the axis L1 of the through hole 23, and the base end side restricting portion 34 are set on the same straight line.

[0042] As shown in FIG. 4, the tip positions of each of the restricting portion 43 and the pair of insulating walls 33 are set at the same position in the Y direction. Further, the tip position of the base-end side restricting portion 34 is set at the same position in the Y direction as the tip positions of the restricting portion 43 and the insulating walls 33. Further, the restricting portion 43, the insulating walls 33, and the base-end side restricting portion 34 are configured to face the barrel portion 17b of the mating terminal 17 in a state of being connected to the terminal connection portion 16 in the circumferential direction centered on the axis L1. Note that the state where the mating terminal 17 is connected to the terminal connection portion 16 includes three states shown by the two-dot chain line in FIG. 3 in addition to the state shown by the solid line in FIG. 3.

[0043] The operation of this embodiment will be described. With the connection portion 17a of the mating terminal 17 overlapped on the surface of the fastened portion 22 of the bus bar 12, the connection portion 17a and the fastened portion 22 are fastened by screwing the bolt B to the nut 14. Note that FIG. 3 shows a range including two fastened portions 22. The mating terminal 17 is bolt-fastened to one of the fastened portions 22, and the other fastened portion 22 shows the state before the mating terminal 17 is bolt-fastened.

[0044] As the circumferential position setting of the mating terminal 17, for example, as shown in FIG. 3, the barrel portion 17b of the mating terminal 17 is arranged to be drawn out from between the restricting portion 43 and the insulating walls 33. When the bolt B is tightened, the mating terminal 17 rotates in the clockwise direction (the rotation direction of the bolt B). When the mating terminal 17 is in the arrangement shown by the solid line in FIG. 3, the barrel portion 17b rotates in the clockwise direction centered on the axis L1 and contacts the restricting portion 43. That is, the restricting portion 43 restricts the rotation of the mating terminal 17 centered on the axis L1. Note that, as described above, the barrel portion 17b may contact the restricting portion 43 due to the rotation of the mating terminal 17 during bolt fastening, but other modes are also possible. That is, the barrel portion 17b may be brought into contact with the restricting portion 43 in advance to determine the position before the bolt fastening, and the mating terminal 17 may be bolt-fastened in that state.

[0045] In this embodiment, there are four ways to set the circumferential position of the mating terminal 17, as shown by the solid line and the two-dot chain line in FIG. 3. The first is the first position where the barrel portion 17b is drawn out from between the regulating portion 43 and one of the insulating walls 33. The second is the second position where the barrel portion 17b is drawn out from between the regulating portion 43 and the other insulating wall 33. The third is the third position where the barrel portion 17b is drawn out from between the proximal-end regulating portion 34 and one of the insulating walls 33. The fourth is the fourth position where the barrel portion 17b is drawn out from between the proximal-end regulating portion 34 and the other insulating wall 33. No matter which of the first to fourth positions the position of the mating terminal 17 is set to, the barrel portion 17b of the mating terminal 17 contacts any one of the regulating portion 43, the pair of insulating walls 33, and the proximal-end regulating portion 34, whereby the rotation of the mating terminal 17 is regulated.

[0046] Also, the regulating portion 43, the pair of insulating walls 33, and the proximal-end regulating portion 34 function as a rotation regulator for the mating terminal 17 even when removing the bolt B. For example, in the case of the arrangement shown by the solid line in FIG. 3, when removing the bolt B, the mating terminal 17 rotates counterclockwise about the axis L1 and the barrel portion 17b contacts the insulating wall 33. Thereby, the rotation of the mating terminal 17 is regulated, and the workability when removing the bolt B is improved.

[0047] Next, the molding mode of the connector 10 will be described. The housing 11 is made by injection molding (insert molding) with the bus bar 12 as an insert part. In this insert molding, the main drawing direction of the upper mold and the lower mold is the direction along the Y direction. Also, when performing this insert molding, a slide mold is used to create a space for arranging the nut 14 between the fastened part 22 and the opposing part 31. This slide mold is arranged between the fastened part 22 and the opposing part 31, and the drawing direction of this slide mold is the tip 22b side (lower side) in the Z direction. For this reason, a restricting part integrally formed with the housing 11 cannot be set on the tip 22b side in the Z direction of the fastened part 22. In this regard, in the present embodiment, a restricting part 43 arranged on the tip 22b side in the Z direction of the fastened part 22 is provided on a nut holding member 13 that is separate from the housing 11. Therefore, it is possible to set the restricting part 43 at a position that cannot be formed on the housing 11 due to molding constraints.

[0048] The effects of the present embodiment will be described. (1) The nut holding member 13 that is separate from the housing 11 has a restricting part 43 that restricts the rotation of the mating terminal 17 around the axis L1 of the through hole 23. For this reason, regardless of the molding constraints of the housing 11, it is possible to set the position of the restricting part 43. Therefore, it is possible to improve the design freedom of the connector 10.

[0049] (2) The terminal connection portion 16 has an extension portion 21 that extends from the housing 11 along the first direction (the Y direction in this embodiment), and a fastened portion 22 that extends from the tip of the extension portion 21 in a second direction (the Z direction in this embodiment) intersecting the first direction. The fastened portion 22 has a through hole 23. The fastened portion 22 is fastened to the mating terminal 17 by a bolt B and a nut 14. The housing 11 has a facing portion 31 that faces the fastened portion 22 in the direction along the axis L1 of the through hole 23. And the nut holding member 13 and the nut 14 are provided between the fastened portion 22 and the facing portion 31. According to this configuration, in the connector 10 where the terminal connection portion 16 of the bus bar 12 is bent, a restricting portion 43 can be provided on the nut holding member 13 that is attached between the fastened portion 22 and the facing portion 31. Also, since the terminal connection portion 16 is bent from the extension portion 21 to the fastened portion 22, it is possible to improve the degree of freedom in setting the circumferential position of the mating terminal 17 that is bolt-fastened to the fastened portion 22.

[0050] (3) The restricting portion 43 is provided near the tip 22b in the Z direction with respect to the fastened portion 22. According to this configuration, in insert molding in which the housing 11 is injection-molded with the bus bar 12 as an insert, when arranging a slide mold to create a space for arranging the nut 14 between the fastened portion 22 of the bus bar 12 and the facing portion 31 of the housing 11. If the extraction direction of this slide mold is along the Z direction, it is not possible to set the restricting portion 43 extending from the housing 11 on the tip 22b side in the Z direction of the fastened portion 22. On the contrary, according to this embodiment, by setting the restricting portion 43 provided on the nut holding member 13 on the tip 22b side in the Z direction of the fastened portion 22, it becomes possible to set the restricting portion 43 at a position where it cannot be provided on the housing 11.

[0051] (4) The housing 11 has insulating walls 33 provided on both sides of the fastened portion 22 in the third direction (the X direction in this embodiment) that is perpendicular to both the Y direction as the first direction and the Z direction as the second direction. According to this configuration, not only the restricting portion 43 of the nut holding member 13 but also the insulating walls 33 of the housing 11 can restrict the rotation of the mating terminal 17. That is, by providing a plurality of portions that restrict the rotation of the mating terminal 17, it becomes possible to prepare a plurality of position settings of the mating terminal 17 in the circumferential direction. Note that the insulating walls 33 are for ensuring an insulating distance around the terminal connection portion 16.

[0052] (5) The housing 11 has a proximal end side restricting portion 34 provided near the proximal end 22a in the Z direction with respect to the fastened portion 22. According to this configuration, at least four walls, namely, the restricting portion 43 of the nut holding member 13, a pair of insulating walls 33, and the proximal end side restricting portion 34, are provided in the connector 10 as portions that restrict the rotation of the mating terminal 17. Thereby, by providing a plurality of portions that restrict the rotation of the mating terminal 17, it becomes possible to prepare at least four position settings of the mating terminal 17 in the circumferential direction.

[0053] (6) The restricting portion 43 has a columnar shape extending along the axis L1 of the through hole 23. According to this configuration, it becomes possible to preferably restrict the rotation of the mating terminal 17 by the columnar restricting portion 43.

This embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range. · The respective numbers of the restricting portion 43 and the proximal end side restricting portion 34 are not limited to those in the above embodiment, and may be appropriately changed according to the configuration of the connector 10. Also, in the above embodiment, the proximal end side restricting portion 34 may be omitted.
