JP-A-11-135102

  By the way, in what was described in patent document 1 mentioned above, while a rotation prevention piece is integrally formed in a battery terminal, the length dimension which adapts to the positional relationship of the contact location by the side of a battery, and a battery post, and It has a shape.

  On the other hand, for example, depending on the type of battery, the installation position of the battery post may be changed. Even for the same type of battery, the installation position of the battery terminal relative to the battery according to the external environment of the battery, etc. Is changed, and the contact portion on the battery side with respect to the rotation stopper piece may be changed accordingly. As described above, since the positional relationship between the contact portion on the battery side and the battery post can be variously changed, it is necessary to manufacture various types of battery terminals having different lengths and shapes of the rotation stopper pieces. For this reason, there has been a problem that the cost required for manufacturing the battery terminal and the like is also increased.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to reduce the cost.

  The battery terminal unit according to the present invention includes a post fitting portion connected to a battery post erected on the battery, and a head portion of the stud bolt that is provided integrally with the post fitting portion and accommodates the stud bolt. In a battery terminal unit comprising a battery terminal having a bolt holding portion that is held in an upright state and a rotation restriction member made of a synthetic resin attached to the battery terminal, the rotation restriction member includes the battery terminal A main body that can regulate the mounting angle of the battery terminal with respect to the battery post by contacting the battery while being connected to the battery post, and is provided integrally with the main body and formed on a side surface of the bolt holding portion. The pressure that causes the rotation restricting member to be fixed to the battery terminal by being press-fitted into the opened opening. And an engagement portion that engages with the bolt holding portion and is disposed at a side of the bolt holding portion and is disposed at a position sandwiching the bolt holding portion between the main body portion and the main body portion. And a connecting portion connected to both the engaging portion and the engaging portion.

  In this way, even when conditions such as the positional relationship between the battery-side contact portion and the battery post with respect to the main body portion are different, the above-described conditions for the rotation restricting member that is relatively inexpensive to manufacture compared to the battery terminal If a battery that conforms to the above is prepared, it is possible to use a common product for battery terminals that are relatively expensive to manufacture, and it is possible to respond at low cost as a whole. Moreover, since the rotation restricting member is fixed to the battery terminal by the press-fitting portion that is press-fitted into the opening formed on the side surface of the bolt holding portion of the battery terminal, rattling is unlikely to occur between the two. Therefore, a high rotation restricting function can be exhibited. Furthermore, the engaging part connected to the main body part by the connecting part engages with the bolt holding part at a position sandwiching the bolt holding part between the main body part and the press-fitting direction of the main body part. Since movement in the opposite direction is restricted, the rotation restricting member attached to the battery terminal can be firmly held. Thereby, an even higher rotation restricting function can be exhibited.

The following configuration is preferable as an embodiment of the present invention.
(1) The connecting portion is provided integrally with the main body portion. In this way, if the connecting part is assembled as a separate part from the main body part, the backlash between the main body part and the main body part may occur compared to the case where the backlash can occur with the main body part. Therefore, a higher rotation restricting function can be exhibited.

(2) The connecting portion can be engaged with an attachment member fastened to the stud bolt to restrict movement of the main body portion in a direction opposite to the press-fitting direction. In this way, the attachment member fastened to the stud bolt is engaged with the joint portion, so that the movement in the direction opposite to the press-fitting direction of the main body portion is doubled in combination with the above-described engagement portion. The And since the connection part is integrally provided in the main-body part, it is especially excellent in the rattling suppression function of the rotation control member with respect to a battery terminal. As described above, an even higher rotation restricting function can be exhibited.

(3) The connecting portion is provided with a receiving portion that receives the protruding portion provided on the mounting member, and the protruding portion is engaged with the wall surface of the receiving portion, thereby press-fitting the main body portion. Movement in the direction opposite to the direction is restricted. If it does in this way, the protrusion of the attachment member received by the receiving part of the connection part will be engaged with the wall surface of a receiving part, and it can aim at prevention of the rotation control member with respect to a battery terminal.

(4) The receiving part is formed in a hole shape penetrating the connecting part, and the hole edge has an endless annular shape. In this way, when the receiving part is formed in a hole shape penetrating the connecting part, the edge of the hole is an endless ring. Therefore, compared to the case where the hole edge is an endless ring, the strength of the connecting part Can be kept high. Thereby, a high retaining force can be exhibited.

(5) The mounting angle of the mounting member with respect to the stud bolt is regulated by contacting the protrusion with a wall surface in the press-fitting direction of the receiving portion. If it does in this way, the attachment angle of the attachment member to a stud bolt can be controlled. Further, since the protrusion has both the function of preventing the rotation restricting member from coming off from the battery terminal and the function of preventing the rotation of the mounting member, it is suitable for simplifying the configuration.

(6) The receiving portion is formed in a hole shape penetrating the connecting portion, and the hole edge has an end-ring shape, whereas the bolt holding portion has the protrusion that has entered the receiving portion. The attachment angle of the attachment member with respect to the stud bolt is regulated by contacting the part. If it does in this way, the attachment angle of the attachment member to a stud bolt can be controlled. In addition, since the projecting portion is in direct contact with the bolt holding portion, the mounting member is less likely to rattle with respect to the bolt holding portion, thereby exhibiting a high detent function. Further, since the protrusion has both the function of preventing the rotation restricting member from coming off from the battery terminal and the function of preventing the rotation of the mounting member, it is suitable for simplifying the configuration.

(7) The mounting member is a terminal fitting connected to an external circuit. In this way, the terminal fitting connected to the external circuit can be provided with a retaining function.

(8) The mounting member is a bracket fixed to the electrical component. If it does in this way, the bracket fixed to an electrical component can also have a retaining function.

(9) The connecting portion is configured to extend along the press-fitting direction of the main body portion with respect to the bolt holding portion, and is adjacent to the bolt holding portion in a direction orthogonal to the axial direction of the stud bolt. It is arranged in. In this way, compared with the bolt holding part, the stud bolt can be attached to the stud bolt in the axial direction of the stud bolt, and the stud bolt can be attached to the stud holding part and the wall surface of the battery. A space for installing the connecting portion can be easily secured at a position adjacent to the direction perpendicular to the axial direction.

(10) A pair of the connecting portions are arranged at positions sandwiching the bolt holding portion, and the engaging portions are connected to both connecting portions. In this way, since the bolt holding part is surrounded by the main body part, the pair of connecting parts, and the engaging part, rattling of the rotation restricting member with respect to the battery terminal in all directions orthogonal to the axial direction of the stud bolt. Can be regulated. And since an engaging part is connected with a pair of connecting part, it is excellent also in intensity | strength and can exhibit a higher omission control function.

(11) The engaging portion is separate from the both connecting portions, and is connected by being assembled to the both connecting portions. If it does in this way, compared with the case where an engaging part is integrally provided in one connection part with a hinge, it is excellent in the assembly | attachment workability | operativity with respect to a battery terminal. This is particularly effective when the distance between the post fitting portion and the bolt holding portion is small.

  According to the present invention, cost reduction can be achieved.

  The first rib 51 and the second rib 52 have substantially the same width dimension and are set larger than the third rib 53. The first rib 51 is disposed at a substantially central position in the Y-axis direction of the insertion protrusion 50, while the second rib 52 is spaced a predetermined distance from the Y-axis direction central position of the insertion protrusion 50. A pair is arranged at the position side by side in the Y-axis direction. In other words, the first rib 51 is arranged at a substantially middle position between the pair of second ribs 52 arranged in the Y-axis direction in the insertion protrusion 50, and conversely, both the second ribs 52 are inserted protrusions. In FIG. 50, the first rib 51 is disposed in the Y-axis direction. That is, the 1st rib 51 and the 2nd rib 52 are distribute | arranged to the position (shift position) mutually offset about the Y-axis direction. Specifically, among the first ribs 51 and the second ribs 52, the end portions in the width direction overlap in the Y-axis direction, but the centers in the width direction do not overlap in the Y-axis direction and are shifted from each other. It has become. In addition, it can be said that both the second ribs 52 are arranged at symmetrical positions around the central position in the Y-axis direction in the insertion protrusion 50.

  The first rib 51 and the second rib 52 have substantially the same protruding dimension from the peripheral surface of the insertion protrusion 50. The dimension obtained by adding the projecting dimension of the first rib 51 and the projecting dimension of the second rib 52 is larger than the dimension difference in the Z-axis direction between the insertion projecting part 50 and the divided opening part 32a. More specifically, the protruding dimension of the first rib 51 or the protruding dimension of the second rib 52 alone is larger than the above dimensional difference. Therefore, when the insertion protrusion 50 is inserted into the divided opening 32a, the first rib 51 and the second rib 52 are crushed by the opening edge of the opening 32, thereby obtaining a desired holding force ( FIG. 14).

  The third rib 53 is disposed at a position spaced a predetermined distance downward from the center position in the Z-axis direction on the outer side surface of the insertion protrusion 50. The protruding dimension of the third rib 53 is smaller than the protruding dimension of the first rib 51 and the second rib 52. The retaining protrusion 54 extends from the inner side surface (the surface facing the other insertion protrusion 50) of the peripheral surface of the insertion protrusion 50, that is, from the side surface opposite to the installation surface of the third rib 53. It protrudes inward along the direction (a fourth direction opposite to the third direction). The third rib 53 and the retaining protrusion 54 have substantially the same installation position in the Z-axis direction in the insertion protrusion 50.

  The retaining protrusion 54 has a substantially block shape as a whole, and is formed in a substantially trapezoidal shape as viewed from the front in the X-axis direction, that is, a tapered shape that becomes narrower toward the protruding end side. The width dimension of the protruding proximal end portion of the retaining protrusion 54 is larger than that of the first rib 51 and the second rib 52. The protruding dimension of the retaining protrusion 54 is larger than any of the ribs 51 to 53. The retaining protrusion 54 is disposed at the lower end position on the side surface of the insertion protrusion 50 and is disposed at a position overlapping the lower third rib 53 in the Z-axis direction. The retaining protrusion 54 is disposed at the tip position of the insertion protrusion 50 in the X-axis direction. Further, a taper surface for ensuring a smooth entry into the opening 32 is chamfered and formed on the front end surface (tip surface in the mounting direction) of the retaining protrusion 54 (FIG. 6).

  As shown in FIG. 6, the dimension obtained by adding the projecting dimension (dimension in the Y-axis direction) of the third rib 53 from the side surface of the insertion projecting part 50 and the projecting dimension of the retaining projection 54 is 50 and the dimensional difference in the Y-axis direction between the divided openings 32a. Furthermore, even if the protrusion dimension of the retaining protrusion 54 alone is larger than the above dimension difference. Therefore, when the insertion protrusion 50 is inserted into the divided opening 32a, the third rib 53 and the retaining protrusion 54 are crushed by the opening edge of the opening 32 (FIG. 14). In particular, the retaining protrusion 54 is slightly cut by the rising portion 34a of the bolt rotation restricting piece 34 that constitutes the opening edge of the opening 32, but can be forcibly fitted to enter the back side of the rising portion 34a. (FIG. 15). The rear end face of the retaining protrusion 54 facing away from the mounting direction with respect to the battery terminal 20, that is, the face facing the terminal receiving portion 43 side is with respect to the rising portion 34 a of the bolt rotation restricting piece 34. The locking surface 54a is locked. The locking surface 54a is formed substantially straight along the Y-axis direction and the Z-axis direction.

  As described above, when the rotation restricting member 40 is attached to the battery terminal 20, the rotation restricting member 40 does not rattle in a state where it cannot be removed by the ribs 51 to 53 of the press-fit portion 42 and the retaining protrusion 54, that is, in a so-called fitted-in state. It is supposed to be retained.

  By the way, as shown in FIG.6 and FIG.8, the thinning part 55 is provided in the insertion protrusion 50 which comprises the press-fit part 42 mentioned above. A pair of the lightening portions 55 are provided on the upper surface of the peripheral surface of the insertion protrusion 50, that is, on the installation surface of the first rib 51, and a pair of the lightening portions 55 are arranged at positions sandwiching the first rib 51. Therefore, it can be said that both the lightening portions 55 are arranged at positions offset from the first rib 51 in the Y-axis direction. Both the thinned portions 55 are arranged at positions where the centers thereof are slightly shifted outward in the Y-axis direction with respect to the centers of the second ribs 52. The thinned portion 55 has a vertically long rectangular shape when viewed from the front in the X-axis direction. Further, the lightening portion 55 is formed by leaving the front end portion of the insertion protrusion 50 by a predetermined thickness and is open only upward. The thinned portion 55 makes it difficult for sink marks to occur in the insertion protrusion 50 when the rotation restricting member 40 is molded with resin.

  The width dimension and the depth dimension (height dimension) in the lightening portion 55 are the same as the projection end of the first rib 51 and the first projection 51 when the insertion projection 50 is viewed from the front in the X-axis direction, as shown in FIG. The size is set so as to deviate (do not cross or overlap) the two lines L1 connecting the protruding ends of the two ribs 52. Further, the depth dimension of the lightening portion 55 is defined by a line L2 passing through the protruding ends of the third rib 53 and the retaining protrusion 54 along the Y-axis direction when the insertion protrusion 50 is viewed from the front in the X-axis direction. It is set to a size that will deviate.

  Now, the rotation restricting member 40 according to the present embodiment includes a connecting piece 56 and an engaging component 57 in addition to the above-described press-fit portion 42 as an attachment structure for the battery terminal 20. As shown in FIG. 1, the engaging part 57 can be engaged with the bolt holding part 22 with the bolt holding part 22 sandwiched between the engaging part 57 and the connecting piece 56. It has a function of mechanically relaying and connecting both the composite part 57 and the main body 41. The connecting piece 56 is integrally provided with the main body portion 41 in a manner similar to the press-fitting portion, whereas the engaging component 57 is separated from the main body portion 41, the press-fit portion 42, and the connecting piece 56. Therefore, it is integrated by being assembled to both connecting pieces 56.

  First, the connecting piece 56 will be described in detail. As shown in FIGS. 1 and 6, the connecting piece 56 is in the same direction as the press-fit portion 42 along the X-axis direction from the side position of the terminal receiving portion 43 in the vertical wall 41 a constituting the main body portion 41. The rotation restricting member 40 is attached to the battery terminal 20 in the mounting direction (the press-fitting direction of the main body 41), and is integrally formed with the main body 41. The connecting piece 56 has a cantilever shape, and its length dimension (dimension in the X-axis direction) is set to be larger than the same dimension of the bolt holding portion 22. Therefore, in a state where the main body 41 is attached to the battery terminal 20, the distal end portion of the connecting piece 56 is forward of the bolt holding portion 22, that is, opposite to the main body portion 41 in the X-axis direction with respect to the bolt holding portion 22. (Fig. 13). A holding protrusion 58 constituting a holding structure for holding the engaging component 57 in the attached state is provided at the tip of the connecting piece 56. A pair of connecting pieces 56 is disposed at a position sandwiching both press-fit portions 42 in the vertical wall 41a of the main body 41, and the interval between the connecting pieces 56 is the width dimension of the bolt holding portion 22 (in the Y-axis direction). Dimension). In the following description, among the connecting pieces 56, when the rear side shown in FIG. 6 is the first connecting piece, the front side of the figure is the second connecting piece, and the two connecting pieces are distinguished. Is a subscript A attached to the code of the first connecting piece, and a subscript B added to the code of the second connecting piece.

  56 A of 1st connection pieces are made into the form extended toward the front from the front surface (surface which faced the battery terminal 20 side) in the vertical wall 41a of the main-body part 41. As shown in FIG. The first connecting piece 56A has substantially the same width over the entire length, and the width dimension thereof is set to be relatively larger than that of the second connecting piece 56B. On the inner side surface (the surface facing the second connecting piece 56B) of the distal end portion of the first connecting piece 56A, an engaging part receiving recessed part 59 for receiving the engaging part 57 is formed in a recessed shape so as to open inward. . Of the peripheral edge of the engagement component receiving recess 59, the front edge portion on the tip side is attached by interfering with the engagement component 57 when the engagement component 57 is about to be attached in the opposite direction. It can be regulated. Furthermore, the holding piece 66 of the engagement component 57 to be described later is inserted into the distal end portion of the first connecting piece 56A by penetrating the first connecting piece 56A in the Z-axis direction, that is, the thickness direction (vertical direction). A possible holding piece insertion hole 60 is provided. The holding piece insertion hole 60 has an elongated rectangular shape in plan view along the X-axis direction. Of the inner peripheral surface of the holding piece insertion hole 60, a holding projection 58 that can hold the holding piece 66 is provided on the inner wall surface (side closer to the battery terminal 20) so as to protrude outward. A receiving wall 61 that receives the tip of the holding piece 66 is provided at the lower end of the holding piece insertion hole 60.

  On the other hand, the 2nd connecting piece 56B is made into the form extended toward the front from the outer side surface of the main-body part 41, and is extending slightly diagonally outward with respect to the X-axis direction about the protrusion base end part. Reinforcing ribs 62 for reinforcement are provided on the outer surface of the protruding proximal end portion of the second connecting piece 56B. A holding piece insertion recess 63 into which the holding piece 66 of the engaging component 57 can be inserted is formed in the outer surface at the tip of the second connecting piece 56B so as to open outward. On the outer surface of the holding piece insertion recess 63, a holding protrusion 58 that can hold the holding piece 66 is provided to protrude outward. A receiving wall 61 that receives the holding piece 66 is provided at the lower end of the holding piece insertion recess 63.

  In the state where the main body 41 is attached to the bolt holding part 22, the main body 41 is arranged side by side in the X-axis direction with respect to the bolt holding part 22, whereas the connecting pieces 56 are connected to the bolt holding part 22. Are arranged side by side with respect to the bolt holding portion 22 in the Y-axis direction, that is, in a direction orthogonal to the axial direction (Z-axis direction) of the stud bolt 24 and the battery post 12. In other words, the connecting pieces 56 are arranged at positions that overlap the bolt holding part 22 in the Y-axis direction but do not overlap in the Z-axis direction. The inner side surfaces of the two connecting pieces 56 are in a state of being close to or in contact with the outer side surface of the bolt holding portion 22 (FIG. 13). The inner surface of the first connecting piece 56A is in a state of being close to or in contact with the outer surface of the bolt holding portion 22 over almost the entire area, whereas the inner surface of the second connecting piece 56B is For the purpose of forming a second receiving portion 68B described later, only a part on the base end side is in a state of being in close contact with or in contact with the outer surface of the bolt holding portion 22.

  Next, the engagement component 57 will be described in detail. The engaging component 57 is made of a synthetic resin like the main body portion 41, and as shown in FIGS. 1 and 6 to 10, a base portion 64 disposed between the tip portions of the connecting pieces 56, and a base portion 64. A pair of side plate portions 65 projecting laterally from both side ends of the pair, a pair of holding pieces 66 respectively suspended from the both side plate portions 65, and projecting from the base portion 64 to the bolt holding portion 22 side and to the bolt holding portion 22. It is comprised from the engaging part 67 engaged with it.

  As shown in FIG. 6, the base portion 64 has a substantially block shape that is elongated along the Y-axis direction. The length of the base portion 64 is larger than the distance between the tip portions of the connecting pieces 56 (the engagement component receiving portion). The recess dimension of the recess 59 is increased. A surface of the base portion 64 facing away from the main body portion 41 (a surface facing the post fitting portion 21 side) is cut into a substantially arc shape along the outer shape of the fastening portion 25 of the post fitting portion 21. It is missing. The base portion 64 is fitted into the space between the bolt holding portion 22 and the post fitting portion 21 in a state where the base portion 64 is attached to the distal end portions of the connecting pieces 56 and attached to the battery terminal 20 ( FIG. 13). In addition, a hollow portion is provided on the lower surface of the base portion 64 so as to open. As shown in FIGS. 6 and 8, the both side plate portions 65 are configured to protrude outwardly along the Y-axis direction from the upper end positions on both outer side surfaces of the base portion 64. Make a flat surface.

  As shown in FIGS. 7 and 8, the two holding pieces 66 protrude downward along the Z-axis direction from the lower surfaces of the side plate portions 65, that is, along the attaching direction of the engaging parts 57 with respect to the connecting pieces 56. Cantilevered. Both holding pieces 66 are elastically deformable with the protruding base end as a fulcrum, and are displaced outwardly along the Y-axis direction, that is, the direction orthogonal to the mounting direction along with the elastic deformation. Yes. A groove 66 a that opens upward is formed at the center in the width direction of both holding pieces 66. When the engaging part 57 is attached to both the holding pieces 66, the holding projection 58 can enter the groove 66a, and the holding projection 58 is locked to the lower edge of the groove edge. (FIG. 16). In other words, both holding pieces 66 have a substantially channel shape when viewed from the side, and their tip portions are locked to the holding protrusions 58 (FIG. 12).

  As shown in FIGS. 6 and 9, the engaging portion 67 is provided so as to protrude from the surface of the base portion 64 facing the main body portion 41 side (the surface facing the bolt holding portion 22 side) toward the main body portion 41 side. (FIG. 6). The engaging portion 67 has an elongated plate shape along the Y-axis direction, and its length dimension is substantially equal to the distance between the connecting pieces 56, that is, the width dimension of the bolt holding portion 22. The engaging portion 67 is partially connected to the base portion 64. Specifically, the engaging portion 67 has four positions in total, that is, both end positions in the length direction of the engaging portion 67 and two positions spaced inward from the both end positions by a predetermined dimension. Are connected to the base 64 by a connecting portion 67a. Accordingly, a portion of the engaging portion 67 arranged between the connecting portions 67a is a bridge portion 67b having a bridge shape (both-end supported shape), and each bridge portion 67b is in the X-axis direction, that is, the base portion 64. On the other hand, it can be elastically deformed slightly in the direction of contact and separation. In other words, thinning is interposed between each bridge portion 67b and the base portion 64, thereby increasing the dimensional accuracy of the thickness dimension of each bridge portion 67b during molding. Among the engaging portions 67, the outer surfaces of the pair of bridge portions 67 b located at both ends (the surfaces facing the bolt holding portions 22) are engaged with the end surfaces of the ceiling wall 22 c constituting the bolt holding portions 22. A pair of engaging protrusions 67c are provided. In a state in which the engaging part 57 is assembled to the distal end portions of the connecting pieces 56, a predetermined interval is provided between the main body portion 41 and the engaging portion 67, and the interval is the length dimension of the bolt holding portion 22 (X (Dimension in the axial direction) is substantially equal (FIG. 13).

  The above-described connecting pieces 56 can be engaged with the terminal fitting 70 attached to the bolt holding portion 22 described above. Specifically, each connecting piece 56 is provided with a receiving portion 68 that receives a detent piece 74 protruding downward from the battery mounting portion 72 of the terminal fitting 70, that is, toward the connecting piece 56. When the battery mounting portion 72 in the terminal fitting 70 is stacked on the bolt holding portion 22, the rotation stopper piece 74 is inserted into the reception portion 68 and the rotation prevention piece 74 with respect to the wall surface of the reception portion 68. Is engaged, the main body 41 integrated with the connecting piece 56 is removed from the bolt holding part 22 integrated with the terminal fitting 70, in other words, the direction opposite to the mounting direction (press-fit direction) of the main body 41. The movement to is restricted. In the following, when the first connecting piece 56A is the first receiving portion, the second connecting piece 56B is the second receiving portion, and the two receiving portions 68 are distinguished. Is a subscript A attached to the code of the first receiving part, and a subscript B is added to the code of the second receiving part.

  68 A of 1st receiving parts penetrate the intermediate part (part corresponding to the bolt holding part 22) between the front-end | tip part and a base end part among the 1st connecting pieces 56A in the thickness direction (Z-axis direction). It is formed in a hole shape (FIG. 21). 68 A of 1st receiving parts are made into the shape suitable for the cross-sectional shape of 74 A of 1st anti-rotation pieces, and have comprised the elongate rectangular shape in the X-axis direction (length direction of 1st connecting piece 56A) seeing in a plane. FIG. 22). Accordingly, the hole edge 68Aa of the first receiving portion 68A has a horizontally long frame shape, that is, an endless annular shape. Of the inner peripheral wall surface of the first receiving portion 68A, the wall surface located on the opposite side of the main body portion 41 in the X-axis direction and along the Y-axis direction (a direction orthogonal to the press-fitting direction of the main body portion 41) By engaging with the end face of the first detent piece 74A facing away from the main body 41, the main body 41 and the rotation restricting member 40 are prevented from coming off (see FIG. 22). This wall surface is a slip-out restricting engagement surface 68Ab for the first detent piece 74A. In other words, it can be said that the first connecting piece 56A has an intermediate portion in the length direction divided into a pair of inner and outer arms by the first receiving portion 68A.

  The inner surface of the first detent piece 74A inserted into the first receiving portion 68A is located closer to the bolt holding portion 22 (inner side) in the Y-axis direction on the inner peripheral wall surface of the first receiving portion 68A and the X-axis. It can contact | abut with respect to the wall surface along a direction (press-fit direction of the main-body part 41) (FIG. 21). This wall surface is a detent contact surface 68Ac for the first detent piece 74A. In the mounted state, the inner edge of the hole edge 68Aa of the first receiving portion 68A in the Y-axis direction is sandwiched between the bolt holding portion 22 and the first rotation stopper piece 74A.

  On the other hand, the second receiving portion 68B has an intermediate portion (a portion corresponding to the bolt holding portion 22) between the distal end portion and the proximal end portion of the second connecting piece 56B in the thickness direction (Z-axis direction). It is configured such that it penetrates and also opens inside (the press-fit portion 42 and the bolt holding portion 22 side) along the Y-axis direction. That is, the second connecting piece 56B has a shape in which the inner side surface (the surface facing the press-fit portion 42, the surface facing the bolt holding portion 22 side) is partially recessed. Accordingly, the hole edge 68Ba of the second receiving portion 68B has a substantially channel shape that is horizontally long when viewed in a plan view, and has an end-like annular shape. And among the inner peripheral wall surfaces of the second receiving portion 68B, the wall surface located on the opposite side to the main body portion 41 in the X-axis direction and along the Y-axis direction (direction orthogonal to the press-fitting direction of the main body portion 41) is By engaging with the end face of the second detent piece 74B facing away from the main body 41, the main body 41 and the rotation restricting member 40 are prevented from coming off (see FIG. 22). This wall surface is a slip-out restricting engagement surface 68Bb for the second detent piece 74B.

  In a state where the rotation restricting member 40 is attached to the battery terminal 20, the opening portion in the Y-axis direction of the hole edge 68 </ b> Ba of the second receiving portion 68 </ b> B is closed over almost the entire length by the first side wall 22 b constituting the bolt holding portion 22. (FIG. 13). When the terminal fitting 70 is attached to the stud bolt 24, the second detent piece 74 enters the second receiving portion 68B and directly against the outer surface of the second side wall 22d of the bolt holding portion 22. The contact is possible. Therefore, in this mounted state, the second anti-rotation piece 74A and the first anti-rotation piece 74B described above sufficiently exhibit the anti-rotation function of the terminal fitting 70 with respect to the bolt holding portion 22 (stud bolt 24). Can do. Further, the distance between the inner surfaces of the both rotation stopper pieces 74 is the sum of the width dimension of the bolt holding part 22 and the width dimension of the inner edge part in the Y-axis direction of the hole edge 68Aa of the first receiving part 68A. It is almost equal to the size. In addition, it can be said that the both anti-rotation pieces 74 have both the anti-rotation function of the terminal fitting 70 and the anti-detachment function of the first connecting piece 56A.

  This embodiment has the structure as described above, and the operation thereof will be described subsequently. First, an operation of attaching the rotation restricting member 40 to the battery terminal 20 in a state where the stud bolt 24 is accommodated in the bolt holding portion 22 is performed.

  At the time of attachment, the main body 41 is moved closer to the battery terminal 20 along the X-axis direction while aligning the bolt holding part 22 of the battery terminal between the connecting pieces 56 of the main body 41. To do. When the main body portion 41 is pushed to a predetermined depth, the bolt holding portion 22 is sandwiched between the connecting pieces 56, and then both the press-fit portions 42 enter into both divided opening portions 32a constituting the opening portion 32 of the bolt holding portion 22. Is done. When the insertion protrusions 50 of the respective press-fit portions 42 are inserted into the respective divided openings 32a, the first rib 51, the second rib 52, and the third rib 53 are associated with the upper edges of the divided openings 32a. Crushing by interfering with the edge, lower edge, and outer side edges. At this time, the retaining protrusion 54 is forcibly fitted while being slightly scraped by interfering with the rising portion 34a of the bolt rotation restricting piece 34 constituting the inner side edge of the opening edge of the divided opening 32a. Viewed from the side of the part 41, it enters the back side of the rising part 34a.

  When each press-fit portion 42 is press-fitted into each divided opening portion 32a to a normal depth, both receiving projections 49 in the terminal receiving portion 43 are abutted against the side end surface of the bolt holding portion 22, so that Pushing is regulated (FIGS. 11 to 13). In this attached state, as shown in FIGS. 14 and 15, the frictional resistance obtained by crushing each of the ribs 51 to 53 and the locking surface 54 a of the retaining protrusion 54 are formed on the bolt rotation restricting piece 34. The main body 41 is held in a substantially non-removable state with respect to the battery terminal 20 by the locking force obtained by locking to the rising portion 34a. Specifically, the main body 41 is held relative to the battery terminal 20 so as not to be displaced relative to the battery terminal 20 by the first rib 51 and the second rib 52 in the Z-axis direction and by the third rib 53 in the Y-axis direction. The protrusion 54 holds the X-axis direction so that relative displacement in the removal direction is impossible (prevention of removal). In addition, in this state, since the bolt holding portion 22 is sandwiched between the connecting pieces 56, the main body portion 41 cannot be displaced relative to the battery terminal 20 in the Y-axis direction. Therefore, the main body 41 is prevented from rattling with respect to the battery terminal 20 in any of the X-axis direction, the Y-axis direction, and the Z-axis direction. In addition, since the second ribs 52 are arranged at predetermined intervals in the insertion protrusions 50, the insertion protrusions 50 are inclined around the axis (X axis) in the divided opening 32a. It is difficult to happen. Furthermore, since the press-fit portions 42 are arranged side by side in the Y-axis direction in the main body portion 41, the main body portion 41 tilts around the Z axis or tilts around the X axis with respect to the battery terminal 20. Is extremely difficult to occur. Further, in this attached state, the leading ends of the connecting pieces 56 are arranged at a position protruding from the bolt holding portion 22 on the side opposite to the main body portion 41 in the X-axis direction, that is, on the post fitting portion 21 side. .

  When the main body 41 is press-fitted and held with respect to the battery terminal 20 as described above, the operation of assembling the engaging component 57 with respect to both the connecting pieces 56 is subsequently performed. The engaging part 57 in a posture in which the engaging part 67 faces the bolt holding part 22 side is pushed from above toward the space between the bolt holding part 22 and the post fitting part 21 in the battery terminal 20, and both connecting pieces Attach to the tip of 56. Then, the engaging part 57 enters between the bolt holding part 22 and the post fitting part 21, and the base part 64 of the engaging part 57 is fitted between the distal end parts of the connecting pieces 56. To be inserted into the holding piece insertion hole 60 or the holding piece insertion recess 63. In this process, each engaging projection 67c of the engaging portion 67 is slidably contacted with the end surface of the ceiling wall 22c of the bolt holding portion 22. At this time, each bridge portion 67b in the engaging portion 67 is the bolt holding portion. Since it can be slightly elastically deformed in the direction away from 22, it is possible to absorb an assembly error with respect to the battery terminal 20, so that the engaging portion 67 is in a substantially intimate state with respect to the bolt holding portion 22. be able to. Further, in the assembling process, each holding piece 66 rides on the corresponding holding projection 58 and is elastically deformed outward.

  When the engaging part 57 is pushed to the normal depth with respect to the distal end portions of the two connecting pieces 56, as shown in FIG. 16, each holding piece 66 gets over each holding projection 58 and is restored, and the groove edge of each groove 66a The engaging parts 57 are held in the assembled state with respect to the connecting pieces 56 by being locked to the holding protrusions 58. At this time, as shown in FIG. 17, the engagement protrusions 67 c in the engagement portion 67 of the engagement component 57 are engaged with the end surfaces of the ceiling wall 22 c of the bolt holding portion 22. Even when a force for pulling out from the terminal 20 is applied, the main body portion 41 integrally connected to the engaging component 57 via both connecting pieces 56 is opposite to the press-fitting direction with respect to the battery terminal 20. Movement in the removal direction is restricted. In this assembled state, the bolt holding portion 22 is sandwiched between the engaging component 57 and the main body portion 41 in the X-axis direction and is also sandwiched by the connecting pieces 56 described above in the Y-axis direction. , The entire circumference is surrounded. Accordingly, the bolt holding portion 22 is restricted from being displaced relative to the main body portion 41 in all directions orthogonal to the axial direction (Z-axis direction) of the stud bolt 24.

  Next, of the battery terminal 20 and the rotation restricting member 40 integrated as described above, an operation of attaching the terminal fitting 70 connected to the electric wire to the bolt holding portion 22 of the battery terminal 20 is performed. The shaft portion 24 b of the stud bolt 24 is inserted into the bolt insertion hole 72 a of the terminal fitting 70 while being aligned, and the main plate portion 71 a of the base portion 71 is brought into contact with the upper surface of the bolt holding portion 22. In this process, the first detent piece 74A is inserted into the hole-shaped first receiving portion 68A in the first connecting piece 56A, and the second detent piece 74B is also opened inward in the second connecting piece 56B. The hole-shaped second receiving portion 68B is inserted.

  In a state where the terminal fitting 70 is attached to the bolt holding portion 22, as shown in FIGS. 18 to 22, the main plate portion 71a of the terminal fitting 70 is brought into contact with the upper surface of the bolt holding portion 22 and the both-turn detent pieces. 74 enters the receiving portion 68 of each corresponding connecting piece 56 and is arranged in contact with or close to the inner peripheral wall surface. In this state, the end face on the opposite side of the main body 41 in the X-axis direction of the anti-rotation pieces 74 and the disengagement restricting engagement surface 68b of the receiving parts 68 are arranged to face each other. Even when a force that pulls in the direction opposite to the press-fitting direction is applied to the main body portion 41, the both-fitting restricting engagement surface 68 b is engaged with the both rotation stopper pieces 74. Coupled with the engagement by the engagement component 57, the main body portion 41 is restricted from being displaced relative to the terminal fitting 70 and the bolt holding portion 22 in the removal direction (FIG. 22). Therefore, the rotation restricting member 40 can be held with a high holding force with respect to the battery terminal 20 via the terminal fitting 70. Moreover, the first detent piece 74A is brought into contact with the detent contact surface 68Ac in the first receiving portion 68A of the first connecting piece 56A, and the second detent piece 74B is in the second side wall 22d in the bolt holding portion 22. The terminal fitting 70 can be prevented from rotating with respect to the stud bolt 24 (see FIG. 21).

  Subsequently, an operation for attaching the battery terminal unit U obtained as described above to the battery 10 is performed. First, the post fitting portion 21 of the battery terminal 20 is fitted to the battery post 12 of the battery 10. At this time, as shown in FIGS. 18 to 20, the rotation regulating wall 41 c constituting the main body 41 of the rotation regulating member 40 is brought into contact with the side surface 11 b of the battery body 11. When the battery terminal 20 is placed on the upper surface 11a of the battery body 11, the bolt 27 and the nut 28 of the post fitting portion 21 are appropriately tightened using a tool. Then, the fastening portion 25 of the post fitting portion 21 is elastically deformed so as to reduce its inner diameter, and its inner peripheral surface is pressed against the outer peripheral surface of the battery post 12, so that the battery terminal 20 is brought into contact with the battery post 12. On the other hand, it is held in an attached state.

  At this time, there is a possibility that the battery terminal 20 is rotationally displaced about its axis (Z axis) around the battery post 12 due to the torque generated as the bolt 27 is tightened. However, as shown in FIGS. 18 and 19, the protrusions 47 of the rotation restricting wall 41 c along the Y axis direction and the Z axis direction of the rotation restricting member 40 integrated with the battery terminal 20 are parallel to each other. Since it is in contact with the side surface 11b of the battery main body 11, the rotation operation of the battery terminal 20 as described above is regulated in advance. Thereby, the attachment angle of the battery terminal 20 with respect to the battery post 12 can be maintained in the state shown in FIG.

  By the way, the battery 10 to which the above-described battery terminal unit U is attached may be changed depending on, for example, the vehicle type and grade on which it is mounted, and the installation position of the battery post 12 in the battery body 11 changes accordingly. May be. Then, the relative positional relationship between the battery post 12 and the side surface 11b (the contact position on the battery 10 side), which is the position where the rotation restricting wall 41c of the rotation restricting member 40 is in contact with the battery body 11, is changed. Will be. On the other hand, since the positional relationship between the post fitting portion 21 and the rotation restricting wall 41c is constant, the battery terminal unit U cannot cope with the change on the battery 10 side. Therefore, in the present embodiment, the rotation restricting member 40 whose body part 41 has a shape suitable for the change on the battery 10 side is manufactured separately, and the rotation restricting member 40 is attached to the battery terminal 20. I am trying to use it. That is, for the battery terminal 20 that is made of metal and relatively expensive to manufacture, a common product is used, whereas the rotation restricting member 40 that is made of synthetic resin and relatively inexpensive to manufacture is subject to various conditions. Matched dedicated products are manufactured and used in a wide variety.

  Specifically, when the distance in the X-axis direction between the battery post 12 and the side surface 11b of the battery body 11 in the battery 10 is larger than that shown in FIG. 19, as shown in FIG. 19 is manufactured in which the length L 'in the X-axis direction of the lateral wall 41b' constituting the main body 41 'as the regulating member 40' is larger than the length L of the one shown in FIG. To do. In this rotation restricting member 40 ′, the vertical reinforcing wall 44 ′ is extended together with the horizontal wall 41 b ′, but other configurations are not changed. Then, when the battery terminal unit U ′ is manufactured by attaching the rotation restricting member 40 ′ to the battery terminal 20, the battery terminal unit U ′ is attached to the battery 10. Then, in a state where the post fitting portion 21 is fitted to the battery post 12, the rotation restriction wall 41 c ′ is brought into contact with the side surface 11 b of the battery 10, so that the rotation restriction function of the battery terminal 20 is satisfactorily exhibited. can do.

  If the distance in the X-axis direction between the battery post 12 and the side surface 11b of the battery body 11 in the battery 10 is smaller than that shown in FIG. What is necessary is just to manufacture what the length dimension of the X-axis direction of the horizontal wall 41b which comprises the part 41 becomes smaller than the length dimension L of what is shown in FIG. In addition to the case where the type of the battery 10 is changed as described above, for example, the attachment angle of the battery terminal 20 with respect to the battery post 12 is changed, and accordingly, the rotation restricting wall 41c of the rotation restricting member 40 is applied. The part on the battery main body 11 side that is in contact may be changed to the side surface 11c along the Z-axis direction and the X-axis direction, but even in such a case, the rotation restricting member 40 having a shape corresponding to that is manufactured. This makes it possible to easily cope with this.

  As described above, the battery terminal unit U of the present embodiment includes the post fitting portion 21 connected to the battery post 12 erected on the battery 10 and the stud bolt integrally provided on the post fitting portion 21. A battery terminal 20 having a bolt holding portion 22 that accommodates 24 heads 24a and holds the stud bolt 24 in an upright state; and a rotation restricting member 40 made of synthetic resin attached to the battery terminal 20. The rotation restricting member 40 includes a main body 41 capable of restricting the mounting angle of the battery terminal 20 with respect to the battery post 12 by contacting the battery 10 with the battery terminal 20 connected to the battery post 12, and a main body Rotation restriction by being press-fitted into the opening 32 formed integrally with the portion 41 and formed on the side surface of the bolt holding portion 22 An engaging part 57 that is arranged at a position sandwiching the bolt holding part 22 between the press-fit part 42 that fixes the material 40 to the battery terminal 20 and the main body part 41 and engages with the bolt holding part 22. And a connecting piece 56 that is arranged on the side of the bolt holding portion 22 and is connected to both the main body portion 41 and the engaging component 57.

  In this way, even when conditions such as a positional relationship between the contact portion on the battery 10 side with respect to the main body portion 41 and the battery post 12 are different, the rotation regulation that is relatively inexpensive to manufacture compared to the battery terminal 20. If a member that meets the above conditions is prepared for the member 40, a common product can be used for the battery terminal 20 that is relatively expensive to manufacture, and the overall cost can be reduced. In addition, the rotation restricting member 40 is fixed to the battery terminal 20 by the press-fit portion 42 that is press-fitted into the opening 32 formed on the side surface of the bolt holding portion 22 of the battery terminal 20. It is difficult for rattling to occur, and thus a high rotation restricting function can be exhibited. Furthermore, the engaging part 57 connected to the main body 41 by the connecting piece 56 engages the bolt holding part 22 at a position sandwiching the bolt holding part 22 between the main body 41 and the main body 41. Since the movement of the portion 41 in the direction opposite to the press-fitting direction is restricted, the rotation restricting member 40 attached to the battery terminal 20 can be firmly held. Thereby, an even higher rotation restricting function can be exhibited.

  By the way, if a lid connected to the main body of the rotation restricting member by a hinge is provided and the battery terminal 20 is sandwiched and held between the lid and the main body, Clearance is likely to occur, and rattling occurs between the two, and the accuracy of the angle at which the rotation can be restricted becomes low, and it is easy to win. Compared with this, in the present embodiment, the rotation restricting member 40 is firmly fixed to the battery terminal 20 by press-fitting, so that the angle of the battery terminal 20 can be regulated with relatively high accuracy. It has become.

  Further, the connecting piece 56 is provided integrally with the main body portion 41. In this way, if the connecting piece is assembled as a separate part from the main body, the backlash between the main body 41 and the main body 41 may occur compared to the case where the backlash may occur with the main body. Since no sticking occurs, a higher rotation restricting function can be exhibited.

  Further, the connecting piece 56 can be engaged with a terminal fitting 70 that is an attachment member fastened to the stud bolt 24 to restrict the movement of the main body 41 in the direction opposite to the press-fitting direction. In this way, the terminal fitting 70 which is an attachment member fastened to the stud bolt 24 is engaged with the connecting piece 56, so that it is in a direction opposite to the press-fitting direction of the main body 41 together with the above-described engaging component 57. Movement to is restricted twice. In addition, since the connecting piece 56 is provided integrally with the main body portion 41, it is particularly excellent in the rattling suppression function of the rotation restricting member 40 with respect to the battery terminal 20. As described above, an even higher rotation restricting function can be exhibited.

  In addition, the connecting piece 56 is provided with a receiving portion 68 that receives the rotation preventing piece 74 provided on the terminal fitting 70, and the rotation preventing piece 74 is engaged with the wall surface of the receiving portion 68, whereby the main body Movement of the portion 41 in the direction opposite to the press-fitting direction is restricted. In this way, the rotation restricting member 74 of the terminal fitting 70 received by the receiving portion 68 of the connecting piece 56 is engaged with the wall surface of the receiving portion 68, so that the rotation restricting member 40 is removed from the battery terminal 20. It can be stopped.

  The first receiving portion 68A is formed in a hole shape penetrating the first connecting piece 56A, and the hole edge 68Aa forms an endless ring. In this case, when the first receiving portion 68A is formed in a hole shape penetrating the first connecting piece 56A, the hole edge 68Aa is an endless ring. In comparison, the strength of the first connecting piece 56A can be kept high. Thereby, a high retaining force can be exhibited.

  Moreover, the mounting angle of the terminal fitting 70 with respect to the stud bolt 24 is regulated by contacting the first detent piece 74A with the wall surface along the press-fitting direction in the first receiving portion 68A. If it does in this way, the attachment angle of terminal fitting 70 to stud bolt 24 can be controlled. Further, since the first detent piece 74A has both a function of preventing the rotation restricting member 40 from coming off from the battery terminal 20 and a function of preventing the terminal fitting 70 from rotating, the first detent piece 74A is suitable for simplifying the configuration.

  Further, the second receiving portion 68B is formed in a hole shape penetrating the second connecting piece 56B, and the hole edge 68Ba forms an end ring, whereas the bolt holding portion 22 includes a second receiving portion. The attachment angle of the terminal fitting 70 with respect to the stud bolt 24 is regulated by the second detent piece 74B that has entered 68B coming into contact therewith. If it does in this way, the attachment angle of terminal fitting 70 to stud bolt 24 can be controlled. In addition, since the second anti-rotation piece 74B is in direct contact with the bolt holding portion 22, the terminal metal fitting 70 is less likely to rattle against the bolt holding portion 22, thereby exhibiting a high anti-rotation function. it can. Further, since the second detent piece 74B has both a function of preventing the rotation restricting member 40 from coming off from the battery terminal 20 and a function of preventing the terminal fitting 70 from rotating, the second detent piece 74B is suitable for simplifying the configuration.

  The mounting member is a terminal fitting 70 connected to an external circuit. In this way, the terminal fitting 70 connected to the external circuit can be provided with a retaining function.

  Further, the connecting piece 56 is configured to extend along the press-fitting direction of the main body portion 41 with respect to the bolt holding portion 22 and is adjacent to the bolt holding portion 22 in a direction orthogonal to the axial direction of the stud bolt 24. It is arranged. In this way, the bolt holding portion 22 is compared to the bolt holding portion 22 in the position adjacent to the stud bolt 24 in the axial direction as compared with the parts attached to the stud bolt 24 and the wall surface of the battery 10. On the other hand, a space for installing the connecting piece 56 can be easily secured at a position adjacent to the direction perpendicular to the axial direction of the stud bolt 24.

  A pair of connecting pieces 56 are arranged at positions sandwiching the bolt holding portion 22, and engaging parts 57 are connected to both connecting pieces 56. In this way, since the bolt holding portion 22 is surrounded by the main body portion 41, the pair of connecting pieces 56, and the engaging component 57, the rotation with respect to the battery terminal 20 is performed in all directions orthogonal to the axial direction of the stud bolt 24. The rattling of the regulating member 40 can be regulated. In addition, since the engaging component 57 is connected to the pair of connecting pieces 56, the strength is excellent and a higher omission control function can be exhibited.

  Further, the engaging component 57 is separated from the connecting pieces 56 and is connected by being assembled to the connecting pieces 56. If it does in this way, compared with the case where an engaging part is integrally provided in one connecting piece by the hinge, it is excellent in the assembly | attachment workability | operativity with respect to the battery terminal 20. FIG. This is particularly effective when the distance between the post fitting portion 21 and the bolt holding portion 22 is small.

<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the shape of the connecting piece 56-A is changed. In the second embodiment, the same structure as that of the first embodiment is denoted by the same reference numeral, and the suffix -A is added to the end thereof, and redundant description of the structure, operation, and effect is omitted. .

  As shown in FIG. 24, both connecting pieces 56-A have receiving portions 68-A that both penetrate in the thickness direction and open inward, and are symmetrical to each other. The hole edges 68a-A of the two receiving portions 68-A are substantially channel-shaped in a plan view and have an end ring shape. That is, the connecting pieces 56-A according to the present embodiment have the same structure as the second connecting piece 56B described in the first embodiment (see FIG. 6). Therefore, when both the locking pieces 74-A of the terminal metal fitting 70-A enter the both receiving portions 68-A, the outer surface of the bolt holding portion 22-A is not interposed without the connecting piece 56-A interposed. Directly against. Accordingly, the clearance that can occur between the bolt holding portion 22-A and the both rotation stopper pieces 74-A does not include the dimensional tolerance of the connecting piece 56-A, and the clearance can be made extremely small. As a result, the terminal fitting 70-A is less likely to rattle against the bolt holding portion 22-A, and a high detent function can be obtained. Moreover, since the width dimension of both connecting pieces 56-A is smaller than that of the first connecting piece 56A described in the first embodiment, it is possible to reduce the size of the rotation restricting member. Further, the distance between the inner surfaces of the both rotation prevention pieces 74-A is substantially equal to the width dimension of the bolt holding portion 22-A.

<Embodiment 3>

As shown in FIG. 25, both connecting pieces 56-B have receiving portions 68-B penetrating in the thickness direction, and are symmetrical to each other. That is, the connecting pieces 56-B according to the present embodiment have the same structure as the first connecting piece 56A described in the first embodiment (see FIG. 6). Since the hole edges 68a-B of the receiving portions 68-B are both endless annular, the strength of the connecting pieces 56-B can be sufficiently secured and equalized. Thereby, even when a force that pulls in the pulling direction opposite to the press-fitting direction is applied to the main body part, the movement of the main body part in the pulling direction can be more reliably regulated. As described above, the holding force of the rotation restricting member with respect to the battery terminal 20-B can be made higher and well balanced, so that a high rotation restricting function can be stably exhibited. In addition, the inner wall surface along the X-axis direction in both receiving portions 68-B is a detent contact surface 68c-B on which both detent pieces 74-B in the terminal fitting 70-B are abutted. Thus, the terminal fitting 70-B can be prevented from rotating with respect to the stud bolt 24-B.

  As shown in FIGS. 26 and 27, a current sensor 80 is attached to the bolt holding portion 22-C of the battery terminal 20-C according to the present embodiment. The current sensor 80 is electrically connected to a predetermined electric circuit using the battery 10-C as a power source via a connector or the like, and detects a current flowing through the electric circuit. The current sensor 80 has a structure in which a bracket 82 is integrally provided with a substantially block-shaped main body portion 81, and the bolt holding portion 22-C in a state where the bracket 82 is inserted into the stud bolt 24-C. Is attached to. The bracket 82 is mounted on the upper surface of the bolt holding portion 22-C and includes a battery mounting portion 83 having a bolt insertion hole 82a, and a pair of detent pieces 84 protruding downward from both side edges of the battery mounting portion 83. Composed. The configurations, operations, and effects of the battery mounting portion 83 and the both rotation prevention pieces 84 are the same as those of the battery attachment portion 72 and the both rotation prevention pieces 74 of the terminal fitting 70 in the first embodiment. Although the bracket 82 is made of metal, it is not for energization but for merely mechanically holding the current sensor 80 with respect to the bolt holding portion 22-C.

  As described above, according to the present embodiment, the attachment member attached to the bolt holding portion 22-C is the bracket 82 fixed to the current sensor 80 that is an electrical component. In this way, the bracket 82 fixed to the current sensor 80 can be provided with a retaining function.
