[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The battery terminal unit of this disclosure is (1) The battery comprises a battery terminal connected to a battery post of the battery, and a base member mounted on the battery terminal, wherein the base member has a base rotation suppression portion that can contact the base contact surface of the battery housing in a direction in which the battery terminal rotates relative to the battery around the axis of the battery post, and a connecting portion for attaching an attachment member that contacts the housing.

[0010] By the base rotation suppression portion of the battery terminal contacting the base contact surface of the battery housing, rotation of the battery terminal relative to the battery is suppressed. When changing the attachment mode of the battery terminal to the battery, the attachment member can be attached to the base member via the connecting portion. Therefore, it is possible to correspond to a plurality of attachment modes, and the versatility of the battery terminal unit can be improved.

[0011] (2) In the battery terminal unit according to (1) above, further comprising the attachment member, the attachment member preferably has an attachment rotation suppression portion that can contact the attachment contact surface of the housing in the direction in which the battery terminal rotates relative to the battery.

[0012] By both the base rotation suppression portion and the attachment rotation suppression portion contacting the housing, the certainty of suppressing rotation of the battery terminal relative to the battery can be enhanced.

[0013] (3) In the battery terminal unit according to (2) above, in a state where the attachment member is attached to the base member, it is preferable that the contact surfaces of each of the attachment rotation suppression portion and the base rotation suppression portion face different directions from each other.

[0014] Since the contact surfaces of each of the attachment rotation suppression portion and the base rotation suppression portion can contact the attachment contact surface and the base contact surface from different directions from each other, when a force in the rotation direction acts on the battery terminal, it is possible to prevent the battery terminal from being displaced relative to the battery.

[0015] (4) In the battery terminal unit according to (2) or (3) above, the connecting portion preferably has a locking hole that opens downward, and the attachment member has a locking portion that is inserted into the locking hole from below with its tip facing upward and is locked.

[0016] Since the attachment member is attached to the base member from below, the attachment member is held stably between the base member and the battery.

[0017] (5) In the battery terminal unit described in any of (1) to (4) above, it is preferable that the connecting portion is provided in multiple locations on different parts of the base member.

[0018] Since various attachment members can be attached to the base member via at least one of the multiple connecting parts, the variations in mounting configurations can be further expanded.

[0019] [Details of the embodiments of this disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples and is intended to be included in the claims, with all modifications in the sense and scope equivalent to the claims.

[0020] <Embodiment 1> As shown in Figure 1, the battery terminal unit 10 of Embodiment 1 includes a battery terminal 20 connected to the battery post 110 of the battery 100, a base member 40 mounted on the battery terminal 20 and in contact with the battery 100, and an intervening member 60 positioned between the battery terminal 20 and the base member 40. In Embodiment 1, as shown in Figures 9, 12, 14, and 16, the battery terminal unit 10 may also be optionally equipped with first to fourth attachment members 80A-80D. In Embodiment 1, multiple types of first to fourth attachment members 80A-80D are provided so that they can be selected as needed. In the following description, the forward and backward directions are defined as forward, right, and upward, respectively, by the reference numerals X, Y, and Z in Figures 1 and 16. The directional references are for convenience only.

[0021] The battery 100 comprises a box-shaped housing 120. The housing 120 has a top surface, a front surface, and a pair of left and right sides. As shown in Figure 1, the housing 120 has a recess 121 in the rightmost and frontmost corner of the rectangle when viewed from above, which is cut out across the front surface, the right side surface, and the top surface. The bottom surface of the recess 121 is part of the top surface of the housing 120. The battery 100 has a battery post 110 that protrudes from the bottom surface of the recess 121. The battery post 110 is cylindrical and tapers in diameter upwards.

[0022] The front surface of the housing 120 is a vertical surface oriented in the left-right and up-down directions, and is configured as a base contact surface 122 that can face and contact the contact surface 45 of the base rotation suppression unit 43, which will be described later. The right side of the housing 120 and the left side of the inner surface of the recess 121 of the housing 120, which faces to the right, are vertical surfaces oriented in the front-back and up-down directions, respectively, and are configured as attachment contact surfaces 123 that can face and contact the contact surface 83 of the attachment rotation suppression unit 81, which will be described later. Both the base contact surface 122 and the attachment contact surface 123 are connected perpendicularly to the bottom surface of the recess 121.

[0023] As shown in Figures 3 and 4, the battery terminal 20 has a terminal body 21 made of conductive metal plate material. The terminal body 21 is formed by punching out the metal plate material and then bending it. The terminal body 21 has a post connection portion 22 and a stud bolt holding portion 23. The post connection portion 22 has an arc-shaped surrounding portion 24 in plan view. As shown in Figure 1, the surrounding portion 24 surrounds the outer circumference of the battery post 110 and is attached to the battery post 110. As shown in Figure 4, the post connection portion 22 has a pair of tightening portions 25 that protrude rearward from both ends in the circumferential direction, which are the rear ends of the surrounding portion 24. Each tightening portion 25 is spaced apart and faces the other in the left-right direction. A bolt 26 is inserted through each tightening portion 25. Of the tightening portions 25, the head 27 of the bolt 26 is placed in one tightening portion 25, and a nut 31 is placed in the other tightening portion 25. As the shaft of the bolt 26 is tightened onto the nut 31, each tightening portion 25 moves closer together in the left-right direction, and the surrounding portion 24 shrinks in diameter. As the surrounding portion 24 shrinks in diameter, the post connection portion 22 is held and connected to the battery post 110 (see Figure 1).

[0024] As shown in Figure 4, the stud bolt holder 23 is positioned in front of the surrounding portion 24. The stud bolt holder 23 is rectangular in plan view, flattened vertically into a rectangular tube shape, and its interior is open in the front-to-back direction. The head (not shown) of the stud bolt 28 is housed inside the stud bolt holder 23. The head of the stud bolt 28 is held inside the stud bolt holder 23. A bolt-through hole 29 is provided in the upper wall of the stud bolt holder 23. The shaft portion 32 of the stud bolt 28 stands upright from the bolt-through hole 29. A fitting or the like connected to the end of an electric wire (not shown) is connected to the shaft portion 32 of the stud bolt 28.

[0025] The base member 40 is made of synthetic resin and, as shown in Figures 5 and 6, has a base base 41, a base mounting portion 42, and a base rotation suppression portion 43. The base base 41, base mounting portion 42, and base rotation suppression portion 43 are all wide plate-like in the left-right direction and are continuous with the same width in the left-right direction. The base mounting portion 42 extends short in the front-rear direction. The base base 41 protrudes upward from the rear end of the base mounting portion 42. The base mounting portion 42 and the base base 41 form an L-shape in side view.

[0026] The base rotation suppression part 43 protrudes downward from the front end of the base mounting part 42. The base mounting part 42 and the base rotation suppression part 43 form an L-shape in side view. The amount of downward protrusion of the base rotation suppression part 43 is greater than the amount of upward protrusion of the base base 41. The upper surface of the base mounting part 42, the front surface of the base base 41, and the front surface of the base rotation suppression part 43 constitute the surface of the base member 40. The surface of this base member 40 is provided with grid-like ribs 44 for reinforcement, strength improvement, etc.

[0027] The lower surface of the base mounting portion 42, the rear surface of the base base portion 41, and the rear surface of the base rotation suppression portion 43 constitute the back surface of the base member 40. As shown in Figure 6, the lower surface of the base mounting portion 42 is a flat surface aligned in the front-rear and left-right directions. The rear surface of the base base portion 41 and the rear surface of the base rotation suppression portion 43 are both vertical surfaces aligned in the up-down and left-right directions. The lower surface of the base mounting portion 42 is positioned facing the bottom surface of the recess 121 of the housing 120 from above (see Figure 1). The rear surface of the base rotation suppression portion 43 is configured as a contact surface 45 that faces the base contact surface 122 of the housing 120 from the front.

[0028] As shown in Figure 1, the base portion 41 is positioned facing the stud bolt holding portion 23 of the battery terminal 20 from the front. The base portion 41 closes the front end opening surface of the stud bolt holding portion 23. As shown in Figures 5 and 6, the base member 40 has a pair of left and right mounting portions 46 that protrude rearward from positions near both ends on the rear surface of the base portion 41. The mounting portions 46 are in the shape of rectangular blocks. Multiple protrusions 47 are provided on the outer surface of each mounting portion 46 so as to extend in the front-rear direction. As shown in Figure 10, each mounting portion 46 is inserted into the stud bolt holding portion 23 from the front. Each protrusion 47 can be crushed by contacting the inner surface of the stud bolt holding portion 23. By press-fitting each mounting portion 46 into the stud bolt holding portion 23 in this way, the base member 40 is held by the terminal body 21 of the battery terminal 20.

[0029] As shown in Figures 5 and 6, the base member 40 has a pair of left and right connecting portions 48 extending rearward from both the left and right ends of the base base 41. Each connecting portion 48 extends in the front-to-back direction and has a gate-shaped cross-section that is elongated in the vertical direction relative to the left-to-right direction. The left and right inner surfaces of each connecting portion 48 and the left and right outer surfaces of each mounting portion 46 face each other in the left-to-right direction. As shown in Figure 1, each connecting portion 48 is positioned along the outer surfaces of the left and right side walls of the stud bolt holding portion 23 of the battery terminal 20. As shown in Figure 10, the left and right side walls of the stud bolt holding portion 23 are sandwiched between each connecting portion 48 and each mounting portion 46.

[0030] Each connecting portion 48 has a locking hole 49 that extends vertically and opens on the lower surface of each connecting portion 48. Each connecting portion 48 has an inner wall portion and an outer wall portion 51 that face each other in the left-right direction via the locking hole 49. The outer wall portion 51 that covers the locking hole 49 from the left and right outer sides is elastically deformable in the left-right direction with the upper end of each connecting portion 48 as a pivot point. As shown in Figure 5, the locking hole 49 opens in a rectangular shape in side view at two locations on the left and right outer surfaces of the outer wall portion 51 that are spaced apart in the front-rear direction. Here, the locking hole 49 opens from the upper part of the outer wall portion 51 to the upper end surface of the connecting portion 48. The lower edge of the opening of the locking hole 49 in the outer wall portion 51 is configured as a locking edge 52 that can be locked onto the locking projection 86 of the first to fourth attachment members 80A-80D, which will be described later, as shown in Figure 10. The locking edge 52 is arranged along the left-right direction and facing upward.

[0031] As shown in Figures 5 and 6, the base member 40 has a pair of left and right base ends 53 that protrude rearward from the rear end of each connecting portion 48. Each base end 53 has a rectangular tubular frame portion 54 that is open in the vertical direction, and claw portions 55 (only one is shown in Figure 5, see Figure 2) that protrude into the interior of the frame portion 54 from the left and right inner surfaces (surfaces facing outward to the left and right).

[0032] The intervening member 60 is made of synthetic resin and has a shape that extends in the left-right direction overall. As shown in Figure 1, the intervening member 60 is sandwiched in the front-rear direction between the post connection portion 22 and the stud bolt holding portion 23 of the battery terminal 20. As shown in Figures 7 and 8, the rear surface of the intervening member 60 is provided with an arc-shaped engaging recess 61 in plan view. As shown in Figure 1, the engaging recess 61 is positioned along the front portion of the outer circumference of the surrounding portion 24 of the post connection portion 22. As shown in Figures 7 and 8, the upper end of the intervening member 60 is composed of a plate-shaped flat portion 62. The engaging recess 61 opens at the rear end of the left-right center portion of the flat portion 62. The intervening member 60 has a pair of left and right elastic lock portions 63 that protrude downward from positions near both left and right ends of the flat portion 62. Each elastic lock portion 63 is plate-shaped and can be elastically deformed in the left-right direction with the connection portion with the flat portion 62 as a fulcrum. As shown in Figure 2, each elastic lock portion 63 is provided with a lock hole 64 that penetrates in the left-right direction. Each elastic locking portion 63 is inserted from below into the frame portion 54 of each base end portion 53. Each claw portion 55 fits into the locking hole 64 of each elastic locking portion 63 and is locked in place. By locking each elastic locking portion 63 to each base end portion 53, the intervening member 60 and the base member 40 are connected to and held together.

[0033] As shown in Figures 7 and 8, a pressing portion 65 is provided on the front surface of the intervening member 60. A weight-reducing portion 66 is provided between the pressing portion 65 and the flat plate portion 62 of the intervening member 60, partially penetrating in the vertical direction. Multiple pressing ribs 67 are provided on the front surface of the pressing portion 65 so as to extend in the vertical direction. Each pressing portion 65 is positioned to cover the rear end opening surface of the stud bolt holding portion 23 from the rear. Each pressing rib 67 can be crushed by contacting the rear end of the upper wall of the stud bolt holding portion 23. With the intervening member 60 held by the base member 40, the engaging recess 61 contacts the post connection portion 22, and each pressing portion 65 contacts the stud bolt holding portion 23 in a pressed state. As shown in Figure 1, the space between the base member 40 and the post connection portion 22 is filled by the intervening member 60.

[0034] Next, a first mounting configuration, which is an example of the use of the battery terminal unit 10, will be described. As shown in Figure 1, in the first mounting configuration, the battery terminal unit 10 is composed of a battery terminal 20, a base member 40, and an intervening member 60, and does not include an attachment member.

[0035] The base member 40 is attached to the battery terminal 20 from the front. Each mounting portion 46 is press-fitted into the post connection portion 22, which prevents the base member 40 from detaching from the battery terminal 20 (see Figure 10). Next, the intervening member 60 is attached to the base member 40 from above. The intervening member 60 is held to the base member 40 by the locking of the claw portions 55 of each base end portion 53 and each elastic lock portion 63, and the base member 40 and the intervening member 60 are held together on the battery terminal 20 (see Figures 2 and 3). This constitutes one form of the battery terminal unit 10.

[0036] Before or after the base member 40 and the intervening member 60 are held on the battery terminal 20, the battery terminal 20 of the battery terminal unit 10 is placed on the bottom surface of the recess 121 in the housing 120 of the battery 100. The surrounding portion 24 of the post connection portion 22 is arranged along the outer circumference of the battery post 110. The heads 27 of the bolts 26 are positioned to the right, which is the opening direction of the recess 121, relative to each tightening portion 25 (see Figure 1).

[0037] In the above state, the bolt 26 rotates and tightens while holding down the nut 31, connecting and fixing the post connection part 22 to the battery post 110. Due to the tightening, a rotational force acts on the battery terminal 20, causing it to rotate horizontally around the battery post 110. Here, the base rotation suppression part 43 of the base member 40 is positioned facing the base contact surface 122 of the housing 120 from the front, which is in the direction of rotation. Therefore, when the battery terminal 20 tries to rotate relative to the battery 100, the contact surface 45 of the base rotation suppression part 43 can come into contact with the base contact surface 122. As a result, the battery terminal 20 is held in a state where it is prevented from rotating relative to the battery 100.

[0038] Next, a second mounting configuration will be described. As shown in Figure 9, the second mounting configuration consists of a battery terminal unit 10 comprising a battery terminal 20, a base member 40, an intervening member 60, and a first attachment member 80A. As shown in Figure 11, the first attachment member 80A of the second mounting configuration has a wall-shaped attachment rotation suppression portion 81 that extends in the front-rear direction. The attachment rotation suppression portion 81 has a rectangular cross-sectional shape that is elongated in the vertical direction relative to the left-right direction. The attachment rotation suppression portion 81 is provided with a plurality of through holes 82. Each through hole 82 extends in the vertical direction and opens on the upper and lower surfaces of the attachment rotation suppression portion 81, respectively. Multiple through holes 82 are arranged in a row in the front-rear and left-right directions. The left side of the attachment rotation suppression portion 81 is configured as a contact surface 83 that faces and can contact the attachment contact surface 123 of the housing 120 of the battery 100. The contact surface 83 of the attachment rotation suppression portion 81 is a vertical surface along the front-rear and vertical directions.

[0039] The first attachment member 80A has a projection 84 that extends to the left from the left side of the attachment rotation suppression part 81. The projection 84 is a rectangular plate in plan view and is connected to the front and upper end of the left side of the attachment rotation suppression part 81. The upper surface of the projection 84 is continuous with the upper surface of the attachment rotation suppression part 81 without any steps. The front end surface of the projection 84 is continuous with the front surface of the attachment rotation suppression part 81 without any steps. The first attachment member 80A also has a plurality (two in this case) of locking parts 85 that project upward from the projection 84. Each locking part 85 is plate-shaped and is connected in pairs to the left end of the projection 84 at a distance from each other in the front-rear direction. A claw-shaped locking projection 86 is provided at the upper end of each locking part 85, projecting to the right.

[0040] The first attachment member 80A is attached to the base member 40 from below. Each locking portion 85 is inserted from below into the locking hole 49 of the right-hand connecting portion 48. During the insertion of each locking portion 85, the outer wall portion 51 of the connecting portion 48 comes into contact with each locking projection 86 and is elastically deformed to the right. When the insertion of each locking portion 85 is complete, the outer wall portion 51 of the connecting portion 48 elastically returns to its original position, and accordingly, each locking projection 86 is positioned to face each locking edge 52 from above (see Figure 10). Each locking projection 86 is positioned so as to be exposed from the locking hole 49 to the right outer surface and upper end surface of the connecting portion 48.

[0041] Each locking projection 86 engages with each locking edge 52, thereby holding the first attachment member 80A in a state where it is restricted from detaching from the base member 40. In particular, the first attachment member 80A is held by being sandwiched vertically between the housing 120 of the battery 100 and the base member 40. The protruding piece 84 is positioned along the bottom surface of the recess 121 of the housing 120. The contact surface 83 of the attachment rotation suppression part 81 is positioned to face the attachment contact surface 123 on the side of the housing 120 so as to be able to contact it from the right.

[0042] In the second mounting configuration, when a rotational force is applied to the battery terminal 20 as it is tightened to the battery post 110, the contact surface 45 of the base rotation suppression unit 43 contacts the base contact surface 122 of the housing 120 from the front, which is in the direction of rotation, and the contact surface 83 of the attachment rotation suppression unit 81 contacts the attachment contact surface 123 of the housing 120 from the right, which is also in the direction of rotation. This prevents the battery terminal 20 from being displaced in the rotational direction relative to the battery 100. In particular, since the respective contact surfaces 45 and 83 of the base rotation suppression unit 43 and the attachment rotation suppression unit 81 face in different directions from each other, and each contact surface 45 and 83 contacts the base contact surface 122 and the attachment contact surface 123 of the housing 120 from different directions from each other, the reliability of suppressing the rotation and displacement of the battery terminal 20 can be increased.

[0043] Next, a third mounting configuration will be described. As shown in Figure 12, the third mounting configuration consists of a battery terminal unit 10 comprising a battery terminal 20, a base member 40, an intervening member 60, and a second attachment member 80B. As shown in Figure 13, the second attachment member 80B of the third mounting configuration has a rectangular bar-shaped attachment rotation suppression portion 81 that extends in the front-rear direction. The attachment rotation suppression portion 81 has a square or rectangular cross-sectional shape when viewed in the front-rear direction. The attachment rotation suppression portion 81 is provided with a plurality of through holes 82. Each through hole 82 extends in the vertical direction and opens on the upper and lower surfaces of the attachment rotation suppression portion 81, respectively. Multiple through holes 82 are arranged in a row in the front-rear direction. The left side of the attachment rotation suppression portion 81 is configured as a contact surface 83 that faces and can contact the attachment contact surface 123 of the housing 120 of the battery 100. The contact surface 83 of the attachment rotation suppression portion 81 is a vertical surface along the front-rear and vertical directions.

[0044] The second attachment member 80B has a projection 84 that extends to the right from the right side of the attachment rotation suppression part 81. The projection 84 is plate-shaped and elongated in the front-rear direction relative to the left-right direction, and is connected to the front and lower end of the right side of the attachment rotation suppression part 81. The lower surface of the projection 84 is continuous with the lower surface of the attachment rotation suppression part 81 without any steps. The front end surface of the projection 84 is continuous with the front surface of the attachment rotation suppression part 81 without any steps. The second attachment member 80B also has a plurality of locking parts 85 that project upward from the projection 84. Each locking part 85 is plate-shaped and is connected in pairs to the right end of the projection 84 at intervals in the front-rear direction. A claw-shaped locking projection 86 is provided at the upper end of each locking part 85, projecting to the left.

[0045] The second attachment member 80B is attached to the base member 40 from below. Each locking portion 85 is inserted from below into the locking hole 49 of the left connecting portion 48. When each locking portion 85 is fully inserted, each locking projection 86 is positioned facing each locking edge 52 from above. By locking each locking projection 86 to each locking edge 52, the second attachment member 80B is held in a state where it is restricted from detaching from the base member 40, and is also held sandwiched between the housing 120 of the battery 100 and the base member 40. The protruding piece 84 and the attachment rotation suppression portion 81 are positioned along the bottom surface of the recess 121 of the housing 120. The contact surface 83 of the attachment rotation suppression portion 81 is positioned to face the attachment contact surface 123 of the recess 121 of the housing 120 so as to be able to contact it from the right.

[0046] When a rotational force is applied to the battery terminal 20 as it is tightened to the battery post 110, the contact surface 45 of the base rotation suppression unit 43 contacts the base contact surface 122 of the housing 120 from the front, which is in the direction of rotation, and the contact surface 83 of the attachment rotation suppression unit 81 contacts the attachment contact surface 123 of the housing 120 from the right, which is also in the direction of rotation. This prevents the battery terminal 20 from being displaced in the rotational direction relative to the battery 100. In particular, since the respective contact surfaces 45 and 83 of the base rotation suppression unit 43 and the attachment rotation suppression unit 81 face in different directions from each other, and each contact surface 45 and 83 contacts the base contact surface 122 and the attachment contact surface 123 of the housing 120 from different directions from each other, the reliability of suppressing the rotation of the battery terminal 20 can be increased. Furthermore, in the third mounting configuration, as shown in Figure 12, the attachment rotation suppression unit 81 is positioned to the side of the entire battery terminal 20 and close to the battery terminal 20, thereby further enhancing the effect of suppressing the rotation of the battery terminal 20.

[0047] Next, a fourth mounting configuration will be described. As shown in Figure 14, the fourth mounting configuration consists of a battery terminal unit 10 comprising a battery terminal 20, a base member 40, an intervening member 60, and a third attachment member 80C. As shown in Figure 15, the third attachment member 80C of the fourth mounting configuration has a left end portion 87 and a right end portion 88 that are positioned opposite each other in the left-right direction, and a covering portion 89 positioned between the left end portion 87 and the right end portion 88. The left end portion 87 has an attachment rotation suppression portion 81, a through hole 82, a contact surface 83, a protruding piece portion 84, a locking portion 85, and a locking projection 86, all of the same shape as the second attachment member 80B of the third mounting configuration. The right end portion 88 has an extension portion 91 that extends in the front-rear direction. The extension portion 91 is plate-shaped, with its plate surface facing left-right. The right end portion 88 also has a protruding piece portion 84 and a plurality of locking portions 85, similar to the left end portion 87. A claw-shaped locking projection 86 is provided at the upper end of each locking portion 85, protruding to the right.

[0048] The cover portion 89 has a pair of left and right legs 92 projecting upward from the left end 87 and the right end 88, respectively, and a top wall portion 93 spanning between the upper ends of each leg portion 92. Each leg portion 92 is plate-shaped and arranged with its plate surface facing left to right. The left leg portion 92 is connected to the left and right inner ends of the rear end of the attachment rotation suppression portion 81. The right leg portion 92 is connected to the rear end of the extension portion 91. The right leg portion 92 and the extension portion 91 are continuous without any steps in the vertical direction. The top wall portion 93 is plate-shaped in the shape of a square or rectangle when viewed from above. The front ends of the top wall portion 93 and each leg portion 92 are positioned at the same location in the front-to-back direction. The rear end of the top wall portion 93 is positioned behind the rear end of each leg portion 92.

[0049] The third attachment member 80C is attached to the base member 40. Each locking portion 85 of the left end 87 is inserted into the locking hole 49 of the left connecting portion 48 from below in a swinging motion. Each locking portion 85 of the right end 88 is inserted into the locking hole 49 of the right connecting portion 48 from below. Here, each locking projection 86 is locked onto the corresponding locking edge 52, thereby holding the third attachment member 80C in a state where it is restricted from detaching from the base member 40. Each projection 84, attachment rotation suppression portion 81, and extension portion 91 are arranged along the bottom surface of the recess 121 of the housing 120. The contact surface 83 of the attachment rotation suppression portion 81 is positioned to face the attachment contact surface 123 of the recess 121 of the housing 120 so as to be able to contact it from the right. When a rotational force is applied to the battery terminal 20, the contact surface 45 of the base rotation suppression part 43 contacts the base contact surface 122 of the housing 120 from the front, and the contact surface 83 of the attachment rotation suppression part 81 contacts the attachment contact surface 123 of the housing 120 from the right. This prevents the battery terminal 20 from being displaced in the rotational direction relative to the battery 100. In particular, in the fourth embodiment, the left and right locking parts 85 are inserted into and locked into the corresponding locking holes 49, so that the third attachment member 80C is stably held on the base member 40. Also in the fourth embodiment, with the third attachment member 80C held on the base member 40, the top wall part 93 is positioned to cover the battery post 110 from above (see Figure 14). The post connection part 22 of the battery terminal 20 is also covered by the top wall part 93. This protects the connection between the battery post 110 and the battery terminal 20 from external elements, preventing short circuits, electric shocks, water damage, and other issues.

[0050] Finally, a fifth mounting configuration will be described. As shown in Figure 16, the fifth mounting configuration consists of a battery terminal unit 10 comprising a battery terminal 20, a base member 40, an intervening member 60, and a fourth attachment member 80D. In the fifth mounting configuration, the arrangement of the recess 121 that accommodates the battery terminal unit 10 differs from that of the first to fourth mounting configurations. The recess 121 in the fifth mounting configuration is a cutout in the left and front corner of the upper square of the housing 120 of the battery 100, extending across the front, left side, and top surfaces. In other words, the recess 121 in the fifth mounting configuration is located at the left end of the housing 120, unlike the recess 121 in the first to fourth mounting configurations which is located at the right end. In the fifth mounting configuration, the attachment contact surface 123 is formed on the left side of the recess 121 of the housing 120. The battery post 110 is erected on the bottom surface of the recess 121, near the right side (the side facing left) of the recess 121. With the battery terminals 20 installed on the bottom surface of the recess 121, the heads 27 of the bolts 26 are positioned relative to each tightening portion 25, facing left, which is the opening direction of the recess 121.

[0051] The fourth attachment member 80D in the fifth mounting configuration has a wall-shaped attachment rotation suppression portion 81 extending in the front-rear direction. The right side of the attachment rotation suppression portion 81 is configured as a contact surface 83 that faces and is in contact with the attachment contact surface 123 of the battery housing 120. The fourth attachment member 80D has a projection portion 84 that extends to the right from the right side of the attachment rotation suppression portion 81. The projection portion 84 is in the shape of a rectangular plate in plan view and is connected to the front and upper end of the right side of the attachment rotation suppression portion 81. The length of the projection portion 84 in the left-right direction is longer than that of the projection portion 84 in the second mounting configuration. The fourth attachment member 80D also has a plurality of locking portions 85 that project upward from the right end of the projection portion 84. Each locking portion 85 has a pair of claw-shaped locking projections 86 that protrude to the right at the upper end of the projection portion 84, spaced apart in the front-rear direction.

[0052] The fourth attachment member 80D is attached to the base member 40 from below. Each locking portion 85 is inserted from below into the locking hole 49 of the left connecting portion 48. Each locking projection 86 is locked to the corresponding locking edge 52, thereby holding the fourth attachment member 80D in a state where it is restricted from detaching from the base member 40. The projection portion 84 is positioned along the bottom surface of the recess 121 of the housing 120. The contact surface 83 of the attachment rotation suppression portion 81 is positioned to face the attachment contact surface 123 of the recess 121 of the housing 120 so as to be able to contact it from the left. When a rotational force is applied to the battery terminal 20, the contact surface 45 of the base rotation suppression portion 43 contacts the base contact surface 122 of the housing 120 from the front, and the contact surface 83 of the attachment rotation suppression portion 81 contacts the attachment contact surface 123 of the housing 120 from the left. This keeps the battery terminal 20 from rotating relative to the battery 100.

[0053] As described above, the battery terminal unit 10 of this embodiment 1 includes a battery terminal 20 connected to the battery post 110 of the battery 100, and a base member 40 attached to the battery terminal 20. The base member 40 has a base rotation suppression portion 43 that can contact the base contact surface 122 of the housing 120 of the battery 100 in the direction in which the battery terminal 20 rotates relative to the battery 100, and a connecting portion 48 for attaching the first attachment members 80A-80D that contact the housing 120.

[0054] The rotation suppression portion 43 of the battery terminal 20 contacts the base contact surface 122 of the housing 120 of the battery 100, thereby suppressing the rotation of the battery terminal 20 relative to the battery 100. When changing the mounting configuration of the battery terminal 20 to the battery 100, the first to fourth attachment members 80A-80D can be attached to the base member 40 via the connecting portion 48. Therefore, it is possible to accommodate various mounting configurations, improving the versatility of mounting the battery terminal unit 10.

[0055] The battery terminal unit 10 includes first to fourth attachment members 80A-80D. The first to fourth attachment members 80A-80D have attachment rotation suppression parts 81 that can contact the attachment contact surface 123 of the housing 120 in the direction in which the battery terminal 20 rotates relative to the battery 100. By having both the base rotation suppression part 43 and the attachment rotation suppression part 81 contact the housing, the reliability of suppressing the rotation of the battery terminal 20 relative to the battery 100 can be increased.

[0056] Furthermore, with the first to fourth attachment members 80A-80D attached to the base member 40, the respective contact surfaces 45 and 83 of the attachment rotation suppression part 81 and the base rotation suppression part 43 face in different directions. This allows the respective contact surfaces 45 and 83 of the attachment rotation suppression part 81 and the base rotation suppression part 43 to contact the attachment contact surface 123 and the base contact surface 122 from different directions. Therefore, when a rotational force is applied to the battery terminal 20, it is possible to prevent the battery terminal 20 from shifting relative to the battery 100.

[0057] Furthermore, the connecting portion 48 has a locking hole 49 that opens downward. The first to fourth attachment members 80A-80D have a locking portion 85 with its tip facing upward, which is inserted into the locking hole 49 from below and locked in place. As a result, the first to fourth attachment members 80A-80D are attached to the base member 40 from below, so that the first to fourth attachment members 80A-80D are held stably between the base member 40 and the battery 100.

[0058] Furthermore, multiple connecting portions 48 are provided at different locations on a single base member 40. This allows various first to fourth attachment members 80A-80D to be attached to the base member 40 via any connecting portion 48, thereby expanding the variations in attachment configurations.
