The body portion 20 as a whole is folded back into a substantially U-shape with the bending connection portion 20c interposed therebetween, and the annular portion 20a and the holding plate-shaped portion 20d and the annular portion 20b and the holding plate-shaped portion 20e extend along the axial direction X, respectively. It is composed of a two-layer laminated structure that is laminated facing each other.

More specifically, the pair of annular portions 20a and 20b are formed in a substantially rectangular annular plate shape with various uneven shapes and notched shapes. Each of the annular portions 20a and 20b has a plate thickness direction along the axial direction X and extends along the first width direction Y and the second width direction Z. As shown in FIG. The annular portion 20a and the annular portion 20b are integrally formed such that the ends on one side in the first width direction Y (the side opposite to the holding portion 22 side) are connected to each other via the bent connecting portion 20c. The pair of annular portions 20a and 20b are positioned to face each other along the axial direction X while being spaced apart along the axial direction X. As shown in FIG. In the fastening portion 21, the annular portion 20a is positioned on the upper side in the vertical direction (on the side opposite to the installation surface of the battery post P), and the annular portion 20b is positioned on the lower side in the vertical direction (on the installation surface side of the battery post P). .

The pair of annular portions 20a and 20b are formed in substantially rectangular annular shapes as described above by forming the post insertion holes 20f and 20g, respectively. The post insertion holes 20f and 20g are holes into which the battery posts P are inserted, and pass through the annular portions 20a and 20b along the axial direction X, respectively. The post insertion holes 20f and 20g are formed in a substantially circular shape corresponding to the outer diameter shape of the battery post P. As shown in FIG. The post insertion hole 20f and the post insertion hole 20g are formed in a positional relationship in which the pair of annular portions 20a and 20b are vertically stacked via the bent connection portion 20c and face each other along the axial direction X. As shown in FIG. Each of the post insertion holes 20f and 20g has an inner peripheral wall surface tapered corresponding to the taper of the battery post P, and each inner peripheral wall surface contacts the battery post P when the battery post P is inserted. .

A slit (gap) 20f is formed in the fastening portion 21 across the pair of annular portions 20a and 20b and the bent connecting portion 20c. The slit 20h extends along the first width direction Y at the ends of the pair of annular portions 20a and 20b on the side of the bending connection portion 20c, and is continuous with the post insertion holes 20f and 20g. It extends along the direction X. In other words, the slits 20h are formed extending from the post insertion holes 20f, 20g to the bent connecting portion 20c so as to partly divide the annular portions 20a, 20g. In the fastening portion 21, the slits 20h are formed at the ends of the pair of annular portions 20a and 20b on the side of the bent connecting portion 20c, and the fastening ends 20i are formed. The tightening end portion 20i is a portion that is tightened by the tightening mechanism 30 when the body portion 20 is fastened to the battery post P. As shown in FIG.

The pair of holding plate-like portions 20d and 20e are each formed in a substantially rectangular plate shape with various uneven shapes and notched shapes. Each of the holding plate-shaped portions 20d and 20e has a plate thickness direction along the axial direction X and extends along the first width direction Y and the second width direction Z. As shown in FIG. The holding plate-shaped portion 20d is formed integrally with the annular portion 20a so as to be continuous along the first width direction Y. As shown in FIG. The holding plate-shaped portion 20e is formed integrally with the annular portion 20b so as to be continuous along the first width direction Y. As shown in FIG. Here, the holding plate-shaped portions 20d and 20e are continuous with the annular portions 20a and 20b with steps therebetween.

The pair of holding plate-shaped portions 20d and 20e is formed with an insertion hole 20j on the side of the holding plate-shaped portion 20d. The insertion hole 20j is a hole through which the shaft portion 10b of the stud bolt 10 is inserted, passes through the holding plate portion 20d along the axial direction X, and opens along the axial direction X. As shown in FIG. The insertion hole 20j is formed in a substantially circular shape with an inner diameter φj slightly larger than the outer diameter (corresponding to the width Hc) of the adjusting portion 10c.

For the holding portion 22, for example, the pair of holding plate-like portions 20d and 20e are bent in a state in which the shaft portion 10b of the stud bolt 10 is inserted through the insertion hole 20j in advance before the bending process. As a result, the holding portion 22 is in a state in which the pair of holding plate-shaped portions 20d and 20e are stacked vertically along the axial direction X, and the stud bolt 10 is held by the pair of laminated holding plate-shaped portions 20d and 20e. The base portion 10a of is sandwiched along the axial direction X and held. Here, the holding plate-like portion 20d constitutes an upper plate in which an insertion hole 20j through which the shaft portion 10b of the stud bolt 10 passes is formed. On the other hand, the holding plate-shaped portion 20e constitutes a lower plate that faces the holding plate-shaped portion 20d, which is the upper plate, in the axial direction X and holds the base portion 10a of the stud bolt 10 between the holding plate-shaped portion 20d and the holding plate-shaped portion 20d. In other words, the pair of holding plate-shaped portions 20d and 20e are stacked facing each other and hold the base portion 10a therebetween. The holding portion 22 holds the base portion 10a by the folded portions 20k and 20l of the holding plate-like portions 20d and 20e so as to embrace the base portion 10a, and the restricting projection portion 20m provided on the holding plate-like portion 20d contacts the base portion 10a. , restricts the rotation of the stud bolt 10 around the shaft portion 10b.

In the stud bolt 10, the base portion 10a is held between the holding plate-shaped portion 20d and the holding plate-shaped portion 20e, and the shaft portion 10b is inserted through the insertion hole 20j, and the stud bolt 10 extends along the axial direction X through the insertion hole 20j. Penetrate. As a result, the shaft portion 10b of the stud bolt 10 protrudes from the insertion hole 20j along the axial direction X and is exposed. is. The stud bolt 10 is assembled with the connection terminal T so that the shaft portion 10b is inserted into the insertion hole Ta of the connection terminal T, and the nut 11 is screwed onto the shaft portion 10b. , and the connection terminal T and the holding plate portion 20d of the fastening portion 21 are conductively connected.

As shown in FIGS. 4, 6 and 7, the stud bolt 10 of this embodiment has a base portion 10a held between a holding plate portion 20d and a holding plate portion 20e, and a shaft portion 10b is inserted therethrough. The adjusting portion 10c is positioned inside the insertion hole 20j while being inserted through the hole 20j. Here, the adjustment portion 10c is formed so that the thickness tc along the axial direction X is slightly thinner than the thickness (plate thickness) tj of the holding plate-like portion 20d. With this configuration, the surface 10ca on the tip side in the axial direction X of the adjustment portion 10c has a level difference with respect to the contact surface 20da of the holding plate-like portion 20d with the connection terminal T, and is positioned so as to fall off. That is, the adjustment portion 10c is positioned such that the surface 10ca is slightly recessed along the axial direction X from the contact surface 20da and is accommodated within the insertion hole 20j.

As shown in FIGS. 1, 2, 3, 4, and 6, the tightening mechanism 30 extends the tightening end portion 20i of the fastening portion 21 of the body portion 20 configured as described above to the second width. It is a mechanism that fastens the body portion 20 to the battery post P by tightening along the direction Z. Here, as an example, the tightening mechanism 30 includes a plate nut 31 as a penetrating member, a tightening bolt 32 as a tightening member, and a bracket 33 as a pressing force conversion member. A force for tightening the portion 20i along the second width direction Z is generated. In this tightening mechanism 30, a plate nut 31 is inserted through the tightening end portion 20i in a positional relationship that crosses the slit 20h along the second width direction Z, and the plate nut 31 is attached to the fastening bolt 32 and the bracket. By assembling 33, it is attached to the clamping end 20i.

In the battery terminal 1 configured as described above, the tightening mechanism 30 tightens the tightening end portion 20i in a state in which the battery post P is inserted into the post insertion holes 20f and 20g of the tightening portion 21 of the body portion 20. Thus, it is fastened to the battery post P. Although detailed description is omitted, when the main body portion 20 is fastened to the battery post P, the fastening mechanism 30 is configured so that the fastening bolt 32 is inserted into the post insertion holes 20f and 20g and the fastening bolt 32 is inserted into the post insertion holes 20f and 20g. Tighten along direction X. Thereby, the tightening mechanism 30 generates a tightening force along the axial direction X between the fastening bolt 32 and the plate nut 31 . Then, the tightening mechanism 30 converts the generated tightening force into a pressing force along the second width direction Z by the action of the plate nut 31 and the bracket 33 . Then, the tightening mechanism 30 tightens the tightening end portion 20i through the plate nut 31 and the bracket 33 by the converted pressing force so as to narrow the width of the slit 20h along the second width direction Z. . As a result, the tightening mechanism 30 can reduce the diameters of the post insertion holes 20f and 20g, thereby tightening the main body 20 to the battery post P to provide electrical continuity. It should be noted that the tightening mechanism 30 is not limited to the above-described type, and is configured including, for example, a bolt and a nut. It may be of a type that is tightened along the two width directions Z.

In the battery terminal 1, the connection terminal T is assembled by inserting the shaft portion 10b of the stud bolt 10 into the insertion hole Ta of the connection terminal T, and the nut 11 is screwed onto the shaft portion 10b so that the shaft The connection terminal T is fastened to the portion 10b, and the connection terminal T and the holding plate portion 20d of the fastening portion 21 are electrically connected.

The battery terminal 1 of the present embodiment is held by the holding portion 22 by the adjustment portion 10c positioned in the insertion hole 20j while the base portion 10a of the stud bolt 10 is held by the holding portion 22 as described above. Positional deviation of the stud bolt 10 can be suppressed. That is, the width Hc of the adjusting portion 10c is smaller than the width Ha of the base portion 10a and larger than the width Hb of the shaft portion 10b. It is possible to suppress the gap between and to reduce the looseness relatively small. With this configuration, the stud bolt 10 can be restrained from rattling in the direction intersecting with the axial direction X while being held by the holding portion 22 .

Thereby, the battery terminal 1 can suppress, for example, misalignment of the center axis C2 of the stud bolt 10 with respect to the center position of the insertion hole 20j. As a result, in the battery terminal 1, for example, since the shaft portion 10b is misaligned, the connecting terminal T assembled to the shaft portion 10b interferes with surrounding objects (for example, the wall surface of the recess of the battery housing Ba). It is possible to suppress the occurrence of a situation in which the shaft portion 10b cannot be attached to the shaft portion 10b.

In the battery terminal 1 described above, the fastening portion 21 fastened to the battery post P and the holding portion 22 are electrically connected, and the connection terminal T is electrically connected to the stud bolt 10 held by the holding portion 22. connected In this configuration, the holding portion 22 is formed with an insertion hole 20j that opens along the axial direction X. As shown in FIG. In the stud bolt 10, the base portion 10a is held by the holding portion 22, the shaft portion 10b passes through the insertion hole 20j along the axial direction X, and the adjustment portion 10c is positioned within the insertion hole 20j. . Here, in the stud bolt 10, the shaft portion 10b is a portion to which the connection terminal T is fastened, and the adjustment portion 10c is provided at the proximal end of the shaft portion 10b and is provided in the cross direction (first The width Hc in the width direction Y and the second width direction Z) is smaller than the width Ha of the base portion 10a and larger than the width Hb of the shaft portion 10b. With this configuration, the battery terminal 1 can suppress positional deviation of the stud bolt 10 held by the holding portion 22 by the adjusting portion 10c positioned in the insertion hole 20j. As a result, the battery terminal 1 can properly hold the stud bolt 10 to which the connection terminal T is electrically connected as described above.

Here, in the battery terminal 1 configured as described above, for example, the stud bolts 10 having different outer diameters (corresponding to the width Hb) of the shaft portions 10b according to the type of the connection partner member such as the connection terminal T. may be used separately. In this case, the plurality of battery terminals 1 may use the stud bolts 10 having shaft portions 10b with different outer diameters, while the body portion 20 and the tightening mechanism 30 are configured in common. In such a case, in the plurality of battery terminals 1, the outer diameters of the shaft portions 10b of the stud bolts 10 are made different, while the outer diameters of the adjustment portions 10c (corresponding to the width Hc) are substantially the same. The inner diameter φj of the insertion hole 20j can be a common inner diameter that matches the outer diameter of the adjusting portion 10c. In addition, even if the stud bolt 10 having the shaft portion 10b with a relatively small diameter is applied to the battery terminal 1 according to the type of the connection mating member such as the connection terminal T, for example, the adjusting portion Positional deviation of the stud bolt 10 held by the holding portion 22 can be suppressed by 10c. In other words, in this case, the adjusting portion 10c has a gap that can be formed between the outer peripheral surface of the shaft portion 10b and the inner peripheral surface of the insertion hole 20j according to the difference in the outer diameter of the shaft portion 10b among the plurality of stud bolts 10. can function as a bolt diameter change absorbing portion for filling the gap, and as a result, versatility can be improved.

As a result, the battery terminal 1 can appropriately hold a plurality of stud bolts 10 having shaft portions 10b with different outer diameters while improving versatility as described above. That is, the battery terminal 1 does not need to prepare the body portion 20 in which the inner diameter φj of the insertion hole 20j is individually changed according to the stud bolt 10 having the shaft portion 10b having a different outer diameter. The body portion 20 having the inner diameter φj matched to the outer diameter of the adjusting portion 10c can be shared, and each stud bolt 10 can be properly held as described above. In other words, in the battery terminal 1, even if the main body portion 20 and the tightening mechanism 30 are configured in common and the stud bolts 10 having shaft portions 10b with different outer diameters are separately used, the stud bolts 10 can be used as described above. 10 can be held properly. As a result, in the battery terminal 1, for example, it is not necessary to create the body portion 20 for each stud bolt 10 having a shaft portion 10b with a different outer diameter, and the shaft portion 10b having a different outer diameter can be formed using a common mold. Since a plurality of types of battery terminals 1 can be manufactured, manufacturing costs can be suppressed.

Here, in the battery terminal 1 described above, the adjusting portion 10c is formed in a cylindrical shape along the axial direction X. As shown in FIG. With this configuration, the battery terminal 1 can easily form the columnar adjusting portion 10c in the stud bolt 10 together with the threaded groove of the shaft portion 10b by rolling, so that the manufacturing cost can be reduced, for example. .

It may be formed in a shape having various uneven portions, such as a columnar shape.

The shaft portion 10b described above may have, for example, an identification shape.

A battery terminal 201 according to the modification shown in FIG. The stud bolt 210 differs from the stud bolt 10 described above in that an identification mark portion 210d is formed on the shaft portion 10b. Other configurations of the battery terminal 201 and the stud bolt 210 are substantially the same as those of the battery terminal 1 and the stud bolt 10 described above.

As an example, the identification mark portion 210d shown in FIG. 8 is formed as a substantially circular concave portion at the tip of the shaft portion 10b. The shape of the identification mark portion 210d varies appropriately according to, for example, the outer diameter of the shaft portion 10b of the stud bolt 210 on which the identification mark portion 210d is provided. rectangular shape, etc.). With this configuration, a plurality of battery terminals 201 to which stud bolts 210 having shaft portions 10b with different outer diameters are applied to a common body portion 20 are attached to the battery terminals 201 according to the outer diameter of the shaft portions 10b. can be easily distinguished from each other.

In the above description, the surface 10ca of the adjusting portion 10c is slightly retracted along the axial direction X from the contact surface 20da and is positioned within the insertion hole 20j, but the present invention is not limited to this.

A battery terminal 301 according to the modification shown in FIG. The stud bolt 310 differs from the stud bolt 10 described above in that it has an adjusting portion 310c instead of the adjusting portion 10c. Other configurations of the battery terminal 301 and the stud bolt 310 are substantially the same as those of the battery terminal 1 and the stud bolt 10 described above.

The adjustment portion 310c according to this modification differs from the adjustment portion 10c described above in the thickness tc along the axial direction X. As shown in FIG. Other configurations of the adjustment unit 310c are substantially the same as those of the adjustment unit 10c described above. Here, the adjustment portion 310c is formed so that the thickness tc along the axial direction X is substantially equal to the thickness (plate thickness) tj of the holding plate-shaped portion 20d. As a result, the surface 310ca of the adjustment portion 310c on the tip side in the axial direction X is substantially aligned with the contact surface 20da of the holding plate portion 20d of the holding portion 22 with the connection terminal T. As shown in FIG. That is, the adjustment portion 310c has the surface 310ca located in the same plane as the contact surface 20da. With this configuration, in the battery terminal 301, not only the contact surface 20da but also the surface 310ca of the adjusting portion 310c can be used as a conduction surface with the connection terminal T, so that a relatively wide contact area with the connection terminal T can be secured. can do. As a result, the battery terminal 301 can ensure better conduction performance.
