Summary of the Invention
Problems to be Solved by the Invention
[0005] Here, for example, as in the case of the EN battery shown in FIG. 10, the positive electrode terminal 20 of the battery 2 may be disposed in a recessed portion 23 formed one step lower than the upper end surface 21 of the battery at the upper end corner of the battery 2. At this time, when the positive electrode terminal 20 is disposed relatively close to each of the recessed portion side walls 231 and 232 constituting the recessed portion 23, the battery terminal 3' needs to be attached so as to be substantially orthogonal to the boundary line RL between the recessed portion bottom surface 230 and the battery side surface 22.
[0006] However, the conventional battery terminal 3' can be connected to the battery 2 obliquely, that is, in a manner intersecting obliquely with respect to the boundary line RL. For this reason, when the battery terminal 3' is connected so as to intersect obliquely with respect to the boundary line RL, with the attachment posture of the battery terminal 3' remaining as it is, the first body 41 interferes with the recessed portion side wall 231, and the fuse unit 4 cannot be connected to the battery terminal 3'. Therefore, in this case, the attachment posture of the battery terminal 3' has to be adjusted so that the battery terminal 3' is orthogonal to the boundary line RL, and there still remains room for improvement in terms of the reduction in the connection work efficiency of the fuse unit 4.
[0007] The present invention has been devised by paying attention to such technical problems, and an object thereof is to provide a battery terminal and a battery fuse terminal capable of improving the connection work efficiency of a fuse unit.
Means for Solving the Problem
[0008] In one aspect of the present invention, there is provided a battery terminal that is connected to a positive electrode terminal protruding upward at the bottom of a recess provided at the upper end of a battery at one end side, and a fuse unit is connected to the other end side. The battery terminal includes a terminal insertion portion provided at one end side of a terminal body through which the positive electrode terminal is inserted, a columnar terminal member provided at the other end side of the terminal body to which the fuse unit is connected, and a movable mechanism that allows the columnar terminal member to move relative to the terminal body with the terminal body fixed to the positive electrode terminal through the terminal insertion portion, so as to be able to change the mounting position of the fuse unit in the horizontal direction.
Effect of the Invention
[0009] According to the present invention, the columnar terminal member is configured to be movable relative to the terminal body by the movable mechanism. Therefore, even when the battery terminal is attached obliquely to the battery, by moving the columnar terminal member relative to the terminal body by the movable mechanism, without adjusting the attachment posture of the battery terminal with respect to the positive electrode terminal, it is possible to avoid the fuse unit interfering with the side wall of the recess of the battery in the attachment posture of the battery terminal, and it becomes possible to connect the fuse unit to the battery terminal. As a result, the workability of connecting the fuse unit to the battery terminal can be improved.

Embodiments for Carrying Out the Invention
[0011] Hereinafter, embodiments of the battery terminal and battery fuse according to the present invention will be described in detail with reference to the drawings. In the following embodiments, an example in which the battery terminal and battery fuse terminal according to the present invention are applied to the EN battery of an automobile, similar to the above-mentioned conventional example, is shown. Also, in the description of each figure, the direction in which the positive terminal 20 of the battery 2 extends is defined as "up", and the direction on the opposite side and in which the second body 42 of the battery fuse terminal 1 extends is defined as "down".
[0012] (Configuration of Battery Fuse Terminal) FIG. 1 shows an exploded perspective view of a battery fuse terminal 1 according to the present embodiment. FIG. 2 shows a perspective view of the battery fuse terminal 1 shown in FIG. 1 attached to a battery 2. FIG. 3 shows a cross-sectional view taken along line A-A of FIG. 2. FIG. 4 shows a cross-sectional view taken along line B-B of FIG. 3.
[0013] As shown in FIGS. 1 and 2, the battery fuse terminal 1 includes a battery terminal 3 connected to the positive terminal 20 of the battery 2, and a fuse unit 4 that houses a plurality of fuses 44 connected between the battery terminal 3 and load connection terminals (not shown) that are connected to the battery terminal 3 and are each electrically connected to each load.
[0014] The battery terminal 3 has a terminal insertion portion 31 at one end of a terminal body 30, through which the positive terminal 20 of the battery 2 is inserted. The terminal insertion portion 31 is provided with a notch portion 32, which is a slit that opens radially in part of the circumferential direction, and the inner diameter of the terminal insertion portion 31 can be expanded or contracted by adjusting the amount of threading of a first nut 53 onto a first stud bolt 51 (see FIG. 3 ) that penetrates the terminal insertion portion 31 in the tangential direction so as to straddle the notch portion 32. In other words, by threading the first nut 53 with the positive terminal 20 inserted into the terminal insertion portion 31, the battery terminal 3 is fastened to the outer periphery of the positive terminal 20.
[0015] The fuse unit 4 has a body 40 made of an insulating resin material that houses a fuse 44 therein, and a bus bar 43 that is a conductive metal plate that is insert-molded from the insulating resin material that makes up the body 40 and that forms an internal circuit to which the fuse 44 is connected. As with the conventional fuse unit, the fuse unit 4 is formed in a generally L-shape that bends along the bottom surface 230 of the recess 23 of the battery 2 and the battery side surface 22.
[0016] The body 40 has a first body 41 disposed generally parallel to the bottom surface 230 of the recessed portion of the battery 2, and a second body 42 connected generally perpendicular to the first body 41 and disposed generally parallel to the battery side surface 22 that is continuous with the bottom surface 230 of the recessed portion of the battery 2, and these are integrally formed. At one longitudinal end of the first body 41, as shown in FIGS. 1, 2, and 4, for example, the periphery of a bolt insertion hole 45 provided at one longitudinal end of a bus bar 43 is exposed to the outside, and the battery terminal 3 and the bus bar 43 are electrically connected via a second stud bolt 54 and a second nut 55. At the longitudinal middle of the second body 42, as shown in FIGS. 1 to 3, the shank of a third stud bolt 56 connected to the bus bar 43 inside the second body 42 is exposed to the outside, and a terminal of an alternator (not shown) is connected to the third stud bolt 56, which is a generator.
[0017] As shown in FIG. 3, the bus bar 43 is formed by bending a conductive metal plate punched out into a predetermined circuit pattern into the L shape. The bus bar 43 penetrates inside the first body 41 and the second body 42, and a plurality of fuses 44 are connected to an intermediate portion in the longitudinal direction. The plurality of fuses 44 are covered by a fuse cover 46 attached to the second body 42.
[0018] (Configuration of Battery Terminal) FIG. 5 shows an exploded perspective view of the battery terminal 3. FIG. 6 shows a perspective view of the battery terminal 3 as viewed from above in the assembled state. FIG. 7 shows a perspective view of the battery terminal 3 as viewed from below in the assembled state. FIG. 8 shows a plan view of the battery terminal 3. FIG. 9 shows a longitudinal cross-sectional view of the battery terminal 3 cut along the line C-C in FIG. 8.
[0019] Particularly, as shown in FIG. 9, the battery terminal 3 has a terminal body 30 composed of an upper plate portion 301 and a lower plate portion 302 which are formed by folding back a single strip-shaped metal plate by 180° with one end portion in the longitudinal direction of the battery terminal 3 as a bent portion and overlapping them with a predetermined interval. Due to the predetermined interval, an internal space S is formed inside the terminal body 30, that is, between the upper plate portion 301 and the lower plate portion 302.
[0020] Also, as shown in FIGS. 5 to 9, at one end side in the longitudinal direction of the terminal body 30, a terminal insertion portion 31 having a substantially circular plan view through which the positive terminal 20 of the battery 2 is inserted is formed to penetrate in the vertical direction. The terminal insertion portion 31 is configured by the first terminal insertion portion 311 formed to penetrate the upper plate portion 301 and the second terminal insertion portion 312 formed to penetrate the lower plate portion 302 being arranged to face each other vertically. Further, at one end portion in the longitudinal direction that is continuous as a bent portion in the terminal body 30, a notch portion 32 that opens in a slit shape outward in the radial direction of the terminal insertion portion 31 is formed across the upper plate portion 301 and the lower plate portion 302.
[0021] Also, at one longitudinal end of the terminal body 30 provided with the notch 32, a pair of bolt insertion holes 331 and 332 through which the first stud bolt 51 is inserted are formed through both side ends (the first side end 351 and the second side end 352) orthogonal to the longitudinal direction. The pair of bolt insertion holes 331 and 332 constitute a first bolt insertion portion 33 that penetrates in the tangential direction of the terminal insertion portion 31 so as to cross the notch 32.
[0022] Further, a first stud bolt 51 having an axial length relatively longer than the total length of the first bolt insertion portion 33 is inserted into the first bolt insertion portion 33 from one end side. A first nut 53 is screwed onto the tip of the shaft portion 512 facing the outside through a washer 52 on the first stud bolt 51. By adjusting the screwing amount of the first nut 53, the interval C (see FIG. 8) of the notch 32 expands and contracts, and the inner diameter of the terminal insertion portion 31 expands and contracts. That is, by screwing the first nut 53, the terminal insertion portion 31 (the first terminal insertion portion 311 and the second terminal insertion portion 312) is pressed against the outer peripheral surface of the positive terminal 20, and the battery terminal 3 is fastened to the positive terminal 20.
[0023] Also, as particularly shown in FIG. 5, the battery terminal 3 is provided with a movable mechanism 6 that enables relative movement of the second stud bolt 54 with respect to the terminal body 30. The movable mechanism 6 is notched in a substantially arc shape extending in the circumferential direction of the terminal insertion portion 31 at the other longitudinal end of the upper surface (upper plate portion 301) of the terminal body 30, and the shaft portion 542 of the second stud bolt 54 as a columnar terminal member is inserted. It is constituted by a long hole 34 as a second bolt insertion portion and a rotation base member 60 that engages with the shaft portion 542 of the second stud bolt 54 inserted into the long hole 34 and is provided so as to be rotatable along the long hole 34 together with the second stud bolt 54.
[0024] 9 , the head 541 of the second stud bolt 54 is sandwiched between the upper plate portion 301 and the lower plate portion 302 and accommodated in the elongated hole 34, with the shank 542 of the second stud bolt 54 facing the outside of the terminal body 30. The tip of the shank 542 of the second stud bolt 54, exposed to the outside from the top surface (upper plate portion 301) of the battery terminal 3 through the elongated hole 34, is inserted into the bolt insertion hole 45 of the bus bar 43 exposed to the outside from the first body 41, and the second nut 55 is screwed in, thereby electrically connecting the fuse unit 4.
[0025] Here, the second stud bolt 54 is a well-known hexagonal bolt, and is desirably arranged in the internal space S so that one flat side surface 541a on the side of the head 541 is closely opposed to a rib 37 that has an arc shape in a plan view and extends circumferentially of the terminal insertion portion 31 on the inner surface of the lower plate portion 302. In other words, the rib 37 can ensure that the second stud bolt 54 is prevented from rotating when the second nut 55 is screwed onto the second stud bolt 54 to fasten the fuse unit 4.
[0026] 5 to 9, the pivotable base member 60 is integrally formed by bending a strip-shaped metal plate having a certain thickness so as to have a generally U-shape in side view. Specifically, the pivotable base member 60 has a first connection piece 61 that faces and is generally parallel to the upper plate portion 301 that constitutes the upper surface of the terminal body 30, a second connection piece 62 that faces and is generally parallel to the lower plate portion 302 that constitutes the lower surface of the battery terminal 3, and a connecting portion 63 that is provided so as to straddle the terminal body 30 from top to bottom and is continuous with the first connection piece 61 and the second connection piece 62 to connect the first connection piece 61 and the second connection piece 62 generally perpendicularly. In this embodiment, the first connection piece 61 and the second connection piece 62 correspond to a pair of connection pieces according to the present invention.
[0027] The first connecting piece 61 and the second connecting piece 62 are arranged substantially parallel to each other and spaced apart at a substantially constant distance C1, and are configured so that the distance C1 between the inner surfaces 611, 621 is slightly larger than the distance C2 between the upper and lower surfaces of the terminal body 30 (see FIG. 9). That is, the first connecting piece 61 and the second connecting piece 62 are configured so that the inner surfaces 611, 621 can slide on the upper and lower surfaces (upper plate portion 301 and lower plate portion 302) of the terminal body 30 that they face, respectively.
[0028] The first connecting piece 61 is also formed with a generally circular second bolt through-hole 64, through which the shank 542 of the second stud bolt 54, which faces outside via the elongated hole 34, passes and engages. That is, the shank 542 of the second stud bolt 54 passes through the second bolt through-hole 64 of the first connecting piece 61, thereby enabling the rotating base member 60 to engage with the second stud bolt 54. The bus bar 43 of the fuse unit 4 is fastened to the second stud bolt 54, thereby enabling the bus bar 43 to be electrically connected to the terminal body 30 via the rotating base member 60.
[0029] In addition, the rotating base member 60 is configured to be engageable with the fuse unit 4 via the upper plate portion 301. That is, as shown in FIG. 4, the fuse unit 4 has, at the lower part of the first body 41, a recess for exposing the periphery of the bolt insertion hole 45 of the bus bar 43 to the outside, and has an engagement recess 47 engageable with the upper plate portion 301, and engages with the upper plate portion 301 via the engagement recess 47. Here, the engagement recess 47 has a pair of side walls 471, 472 having a height greater than the thickness of the upper plate portion 301 on both sides in the width direction with the bolt insertion hole 45 interposed therebetween at the lower part of the first body 41. That is, by engaging the pair of side walls 471, 472 with both side surfaces 301a, 301b of the upper plate portion 301, the first body 41 (fuse unit 4) and the rotating base member 60 can rotate integrally. In other words, by engaging the pair of side walls 471, 472 with both side surfaces 301a, 301b of the upper plate portion 301, the relative rotation of the first body 41 (fuse unit 4) about the second stud bolt 54 with respect to the rotating base member 60 is restricted.
[0030] Further, as shown in FIGS. 5 to 9, the upper plate portion 301 and the lower plate portion 302 of the terminal body 30 are each provided with a pair of guide holes, i.e., a first guide hole 361 and a second guide hole 362, which extend in a substantially arc shape with a radius of curvature corresponding to the long hole 34 at a position on the inner peripheral side (terminal insertion portion 31 side) of the long hole 34. Further, the first guide hole 361 and the second guide hole 362 have a predetermined circumferential width corresponding to the circumferential width of the long hole 34. Specifically, the first guide hole 361 and the second guide hole 362 guide the rotation of the rotating base member 60 along the long hole 34 via the first locking protrusion 651 and the second locking protrusion 652 described later, and are formed so as to be able to restrict unnecessary relative rotation of the rotating base member 60 about the second stud bolt 54 with respect to the terminal body 30.
[0031] On one hand, the first connection piece 61 and the second connection piece 62 each have, at their respective tip portions, a pair of locking protrusions 651 and 652 which are formed by bending toward the side facing the upper plate portion 301 and the lower plate portion 302 of the terminal body 30. The first locking protrusion 651 is locked to the first guide hole 361 from the upper surface side of the terminal body 30. The second locking protrusion 652 is locked to the second guide hole 362 from the lower surface side of the terminal body 30. That is, by locking the first locking protrusion 651 and the second locking protrusion 652 to the first guide hole 361 and the second guide hole 362 respectively, while suppressing the detachment of the rotation base member 60 from the terminal body 30, the relative rotation of the rotation base member 60 with respect to the terminal body 30 is guided. With such a configuration, the rotation base member 60 can rotate relative to the terminal body 30 along the long hole 34 together with the second stud bolt 54 while the first locking protrusion 651 and the second locking protrusion 652, which are a pair of locking protrusions, are respectively guided by the first guide hole 361 and the second guide hole 362, which are a pair of guide holes.
[0032] Further, by locking the first locking protrusion 651 and the second locking protrusion 652 to the first guide hole 361 and the second guide hole 362 respectively, the relative rotation range of the rotation base member 60 with respect to the terminal body 30 can be controlled within the circumferential range of the first guide hole 361 and the second guide hole 362. That is, by locking the first locking protrusion 651 and the second locking protrusion 652 to the first guide hole 361 and the second guide hole 362, excessive relative rotation of the rotation base member 60 centered on the second stud bolt 54 with respect to the terminal body 30 is restricted.
[0033] (Method of Assembling Battery Terminal) Hereinafter, with reference to FIG. 1, the method of assembling the battery fuse terminal 1 will be described.
[0034] First, the positive terminal 20 of the battery 2 is inserted into the terminal insertion portion 31 of the battery terminal 3, and the first nut 53 is tightened to fix the battery terminal 3 to the positive terminal 20. Next, the shaft portion 542 of the second stud bolt 54 of the battery terminal 3 is inserted into the bolt insertion hole 45 of the fuse unit 4, and the second nut 55 is tightened to connect the battery fuse terminal 1 to the battery terminal 3.
[0035] Here, when the battery terminal 3 is connected perpendicular to the battery 2, i.e., roughly perpendicular to the boundary line RL of the battery 2, the fuse unit 4 is connected to the battery terminal 3 as is. That is, without changing the horizontal position of the second stud bolt 54 of the battery terminal 3, the shaft 542 of the second stud bolt 54 of the battery terminal 3 is inserted into the bolt insertion hole 45 of the fuse unit 4, and the battery fuse terminal 1 is connected to the battery terminal 3.
[0036] On the other hand, there may be cases where the battery terminal 3 is connected obliquely to the battery 2, i.e., diagonally intersecting the boundary line RL of the battery 2, and the fuse unit 4 cannot be connected to the battery terminal 3 in its installed position. In this case, as shown in FIG. 1 , the second stud bolt 54 of the battery terminal 3 and the pivotable base member 60 are rotated together along the elongated hole 34 in the horizontal direction away from the recessed portion sidewall 231 of the battery 2 to which the battery terminal 3 is adjacent. The shaft 542 of the rotated second stud bolt 54 is then inserted into the bolt insertion hole 45 of the fuse unit 4, thereby connecting the battery fuse terminal 1 to the battery terminal 3. In this way, by changing the horizontal position of the second stud bolt 54 via the movable mechanism 6, the fuse unit 4 can be assembled to the battery terminal 3 without changing the installed position of the battery terminal 3 relative to the positive terminal 20.
[0037] (Effects of this embodiment) As described above, the battery terminal 3 (battery fuse terminal 1) according to the present embodiment is connected to the positive electrode terminal 20 that protrudes upward at the bottom surface (recess bottom surface 230) of the recess 23 provided at the upper end portion of the battery 2 on one end side, and the fuse unit 4 is connected to the other end side. It is a battery terminal (battery fuse terminal) in which a terminal insertion portion 31 provided on one end side of the terminal body 30 and through which the positive electrode terminal 20 is inserted, and a columnar terminal member (second stud bolt 54) provided on the other end side of the terminal body 30 to which the fuse unit 4 is connected, and the terminal body 30 is fixed to the positive electrode terminal 20 via the terminal insertion portion 31. And a movable mechanism 6 that allows the columnar terminal member (second stud bolt 54) to move relative to the terminal body 30 so as to be able to change the mounting position of the fuse unit 4 in the horizontal direction.
[0038] As described above, in the battery terminal 3 and the battery fuse terminal 1 according to the present embodiment, the second stud bolt 54, which is a columnar terminal member, is configured to be movable relative to the terminal body 30 by the movable mechanism 6. For this reason, when the battery terminal 3 is attached obliquely to the battery 2, that is, obliquely intersecting the boundary line RL between the recess bottom surface 230 of the battery 2 and the battery side surface 22, the second stud bolt 54 can be moved relative to the terminal body 30 in the horizontal direction by the movable mechanism 6. As a result, without adjusting the mounting posture (horizontal position) of the battery terminal 3 with respect to the positive electrode terminal 20, the interference of the fuse unit 4 (first body 41) with the recess side walls 231 and 232 of the battery 2 is avoided while maintaining the mounting posture (horizontal position) of the battery terminal 3, and the fuse unit 4 can be connected to the battery terminal 3. As a result, the connection workability of the fuse unit 4 to the battery terminal 3 can be improved.
[0039] Further, in the present embodiment, the movable mechanism 6 is provided so as to extend in an arc shape in the circumferential direction of the terminal insertion portion 31 in the terminal body 30, and includes a long hole 34 through which a columnar terminal member (second stud bolt 54) is inserted, and engages with the columnar terminal member (second stud bolt 54) inserted through the long hole 34, and a rotation base member 60 that rotates along the long hole 34 together with the columnar terminal member (second stud bolt 54). It is preferable that the columnar terminal member (second stud bolt 54) is rotated in the circumferential direction of the terminal insertion portion 31.
[0040] Thus, in the present embodiment, the second stud bolt 54, which is a columnar terminal member, can be rotated in the circumferential direction of the terminal insertion portion 31. Therefore, when the battery terminal 3 is obliquely connected to the battery 2, the second stud bolt 54 is relatively rotated with respect to the battery terminal 3 via the rotation base member 60. In this way, by configuring the second stud bolt 54 to be relatively rotatable in the horizontal direction with respect to the battery terminal 3, for example, compared with the case of moving the second stud bolt 54 in the extending direction of the battery terminal 3, that is, along the longitudinal direction of the terminal body 30, the battery fuse terminal 1 can be arranged in a relatively compact manner. As a result, an increase in the size of the battery fuse terminal 1 can be suppressed.
[0041] Further, in the present embodiment, the rotation base member 60 includes a pair of connection pieces 61 and 62 provided in parallel with each other, the first connection piece 61 facing the upper surface of the terminal body 30 and the second connection piece 62 facing the lower surface of the terminal body 30, and a connection portion 63 provided so as to straddle the upper and lower portions of the terminal body 30 and connected to the pair of connection pieces 61 and 62 to vertically connect the pair of connection pieces 61 and 62. The fuse unit 4 has an engaging portion (engaging recess 47) that engages with the first connection piece 61 in a state of being connected to the columnar terminal member (second stud bolt 54). It is preferable that the fuse unit 4 rotates integrally with the rotation base member 60 when the first connection piece 61 engages with the engaging portion (engaging recess 47).
[0042] Thus, in this embodiment, the first connection piece 61 of the rotating base member 60 engages with the engaging recess 47 provided in the fuse unit 4 (the first body 41), so that the fuse unit 4 can rotate synchronously with the rotating base member 60 as a whole. Therefore, the relative rotation of the fuse unit 4 with respect to the rotating base member 60 is restricted, and the interference between the battery 2 and the fuse unit 4 caused by the relative rotation of the fuse unit 4 with respect to the rotating base member 60 can be suppressed.
[0043] Also, in this embodiment, the rotating base member 60 includes a pair of connection pieces (the first connection piece 61 and the second connection piece 62) provided parallel to each other so as to face the upper and lower surfaces of the terminal body 30, and a connection piece provided so as to straddle the upper and lower sides of the terminal body 30. The connecting portion 63 that is continuous with the pair of connection pieces (the first connection piece 61 and the second connection piece 62) and vertically connects the pair of connection pieces (the first connection piece 61 and the second connection piece 62). A pair of guide holes (the first guide hole 361 and the second guide hole 362) extending in a long hole shape along the arc of the long hole 34 are provided on the upper and lower surfaces of the terminal body 30 on one side in the radial direction of the long hole 34. On the inner side surfaces 611 and 621 of the pair of connection pieces (the first connection piece 61 and the second connection piece 62) facing the upper and lower surfaces of the terminal body 30, a pair of locking protrusions (the first locking protrusion 651 and the second locking protrusion 652) that can be locked to the pair of guide holes (the first guide hole 361 and the second guide hole 362) are provided. This is preferable.
[0044] Thus, in this embodiment, by locking the first locking protrusion 651 and the second locking protrusion 652, which are a pair of locking protrusions, to the first guide hole 361 and the second guide hole 362, which are a pair of guide holes, respectively, it is possible to restrict the rotation range of the rotating base member 60 with respect to the terminal body 30. In this way, by restricting the relative rotation range of the rotating base member 60 with respect to the terminal body 30, it is possible to restrict the rotation range of the fuse unit 4 with respect to the terminal body 30 to an appropriate range. Thereby, the interference between the battery 2 and the fuse unit 4 caused by the fuse unit 4 rotating relative to the terminal body 30 more than necessary can be suppressed.
[0045] Furthermore, by engaging the first locking projection 651 and the second locking projection 652, which are a pair of locking projections, with the first guide hole 361 and the second guide hole 362, which are a pair of guide holes, respectively, the first locking projection 651 and the second locking projection 652 are guided by the first guide hole 361 and the second guide hole 362 when the rotating base member 60 rotates. This ensures smooth rotation of the rotating base member 60 relative to the battery terminal 3, further improving the ease of connecting the fuse unit 4.
[0046] The present invention is not limited to the configurations exemplified in the above-described embodiments, and can be freely modified in accordance with the specifications of the object of application within the scope of the present invention.
[0047] In particular, the battery fuse terminal to which the present invention is applied is not limited to the L-shaped bent form exemplified in the above embodiment.
