It extends along the direction X. In other words, the slit 20h is formed so as to extend from the post insertion holes 20f, 20g to the bending connecting portion 20c so as to divide a part of the annular portions 20a, 20. In the fastening portion 21, the portion where the slit 20h is formed at the end portion of the pair of annular portions 20a and 20b on the bending connecting portion 20c side constitutes the tightening end portion 20i. The tightening end portion 20i is a portion that is tightened by the tightening mechanism 30 when the main body portion 20 is fastened to the battery post P.

The pair of holding plate-shaped portions 20d and 20e are formed in a substantially rectangular plate shape with various uneven shapes and notched shapes, respectively.

The holding plate-shaped portion 20d is integrally formed with the annular portion 20a so as to be continuous along the first width direction Y. The holding plate-shaped portion 20e is integrally formed with the annular portion 20b so as to be continuous along the first width direction Y. Here, the holding plate-shaped portions 20d and 20e are continuous with a step between the annular portions 20a and 20b, respectively.

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

In the holding portion 22, for example, the pair of holding plate-shaped portions 20d and 20e are bent in a state where the shaft portion 10b of the stud bolt 10 is inserted into the insertion hole 20j in advance before the bending process. As a result, the holding portion 22 is in a state in which a pair of holding plate-shaped portions 20d and 20e are vertically laminated along the axial direction X, and the laminated holding plate-shaped portions 20d and 20e make the stud bolt 10 The base portion 10a of the above is sandwiched and held along the axial direction X. Here, the holding plate-shaped portion 20d constitutes an upper plate in which an insertion hole 20j through which the shaft portion 10b of the stud bolt 10 penetrates 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. That is, the pair of holding plate-shaped portions 20d and the holding plate-shaped portions 20e are laminated so as to face each other and hold the base portion 10a between them. The holding portion 22 is held by the folded portions 20k and 20l of the holding plate-shaped portions 20d and 20e so as to embrace the base portion 10a, and the regulation protrusion 20m provided on the holding plate-shaped portion 20d abuts on the base portion 10a. , The rotation of the stud bolt 10 around the shaft portion 10b is regulated.

In the stud bolt 10, the shaft portion 10b is inserted into the insertion hole 20j with the base portion 10a held between the holding plate-shaped portion 20d and the holding plate-shaped portion 20e, and the insertion hole 20j is inserted along the axial direction X. Penetrate. As a result, the shaft portion 10b of the stud bolt 10 is exposed by protruding from the insertion hole 20j along the axial direction X, and the connection terminal T is fastened to the exposed shaft portion 10b via the nut 11 so that the stud bolt 10 can be electrically connected. Is. The stud bolt 10 has a shaft portion 10b in which a nut 11 is screwed into the shaft portion 10b in a state where the connection terminal T is assembled so that the shaft portion 10b is inserted into the insertion hole Ta of the connection terminal T. The connection terminal T is fastened to the connection terminal T, and the connection terminal T and the holding plate-shaped portion 20d of the fastening portion 21 are electrically connected to each other.

Then, as shown in FIGS. 4, 6 and 7, in the stud bolt 10 of the present embodiment, 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. The adjusting portion 10c is located in the insertion hole 20j in a state of being inserted into the hole 20j. Here, the adjusting 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-shaped portion 20d. With this configuration, the adjusting portion 10c is positioned so that the surface 10ca on the tip end side in the axial direction X has a step with respect to the contact surface 20da of the holding plate-shaped portion 20d with the connection terminal T and is dropped. That is, the adjusting portion 10c is positioned so that the surface 10ca is slightly retracted along the axial direction X with respect to the contact surface 20da and is accommodated in the insertion hole 20j.

As shown in FIGS. 1, 2, 3, 4, 6, 6 and the like, the tightening mechanism 30 has a second width of the tightening end portion 20i of the fastening portion 21 of the main body portion 20 configured as described above. It is a mechanism for fastening the main body 20 to the battery post P by tightening along the direction Z. Here, as an example, the tightening mechanism 30 is configured to include a plate nut 31 as a penetrating member, a fastening bolt 32 as a fastening member, and a bracket 33 as a pressing force conversion member, which work together to tighten the tightening end. A force is generated to tighten the portion 20i along the second width direction Z. The tightening mechanism 30 is inserted into the tightening end portion 20i so that the plate nut 31 crosses the slit 20h along the second width direction Z, and the fastening bolt 32 and the bracket are inserted into the plate nut 31. By assembling 33, it is attached to the tightening end portion 20i.

The battery terminal 1 configured as described above tightens the tightening end portion 20i by the tightening mechanism 30 in a state where the battery post P is inserted into the post insertion holes 20f and 20g of the fastening portion 21 of the main body portion 20. It is fastened to the battery post P. Although detailed description will be omitted, when the main body 20 is fastened to the battery post P, the tightening mechanism 30 is aligned with the fastening bolt 32 with the battery post P inserted in the post insertion holes 20f and 20g. Tighten along the direction X. As a result, 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 via 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, and fasten the main body 20 to the battery post P to conduct conduction. The tightening mechanism 30 is not limited to the above type, and includes, for example, bolts and nuts. By tightening the bolts along the second width direction Z, the tightening end portion 20i is tightened. 2 It may be of a type of tightening along the width direction Z.

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

Then, the battery terminal 1 of the present embodiment is held by the holding portion 22 by the adjusting portion 10c located in the insertion hole 20j in a state where the base portion 10a of the stud bolt 10 is held by the holding portion 22 as described above. The misalignment of the stud bolt 10 can be suppressed. That is, the adjusting portion 10c is formed so that the width Hc is smaller than the width Ha of the base portion 10a and larger than the width Hb of the shaft portion 10b, so that the adjusting portion 10c is positioned in the insertion hole 20j and is in contact with the inner peripheral surface of the insertion hole 20j. It is possible to suppress the gap between the spaces relatively small and reduce the backlash. With this configuration, the stud bolt 10 can suppress rattling in the direction intersecting the axial direction X while being held by the holding portion 22.

As a result, the battery terminal 1 can prevent the center axis C2 of the stud bolt 10 from being misaligned with respect to the center position of the insertion hole 20j, for example. As a result, in the battery terminal 1, for example, the shaft portion 10b is misaligned, so that the connection terminal T to be assembled to the shaft portion 10b interferes with a surrounding object (for example, the recessed wall surface of the battery housing Ba). It is possible to prevent a situation in which the shaft portion 10b cannot be assembled.

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 to. In this configuration, the holding portion 22 is formed with an insertion hole 20j that opens along the axial direction X. Then, in the stud bolt 10, the shaft portion 10b penetrates the insertion hole 20j along the axial direction X while the base portion 10a is held by the holding portion 22, and the adjusting portion 10c is located in 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 adjusting portion 10c is provided at the base end of the shaft portion 10b and intersects the axial direction X (first). The width Hc in the width direction Y and the second width direction Z) is formed to be 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 the misalignment of the stud bolt 10 held by the holding portion 22 by the adjusting portion 10c located 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 portion 10b depending on the type of the connection partner member such as the connection terminal T. May be used properly. In this case, the plurality of battery terminals 1 may use stud bolts 10 having different outer diameters of the shaft portions 10b after having the main body portion 20 and the tightening mechanism 30 having a common configuration. In such a case, the plurality of battery terminals 1 have different outer diameters of the shaft portion 10b between the stud bolts 10, while the outer diameter of the adjusting portion 10c (corresponding to the width Hc) is made 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. On top of that, even if a stud bolt 10 having a shaft portion 10b having a relatively small diameter is applied to the battery terminal 1 depending on the type of the connection partner member such as the connection terminal T, the adjusting portion is described as described above. With 10c, the misalignment of the stud bolt 10 held by the holding portion 22 can be suppressed. That is, in this case, the adjusting portion 10c has a gap that may occur 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. It can function as a bolt diameter change absorbing part for filling the above, 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 different outer diameters of the shaft portions 10b, while improving the versatility as described above. That is, for example, the battery terminal 1 does not need to prepare the main body portion 20 in which the inner diameter φj of the insertion hole 20j is individually changed according to the stud bolts 10 having different outer diameters of the shaft portion 10b. The main body portion 20 whose inner diameter φj is matched with the outer diameter of the adjusting portion 10c can be shared, and each stud bolt 10 can be properly held on the main body portion 20 as described above. In other words, the battery terminal 1 has a common configuration of the main body 20 and the tightening mechanism 30, and even if the stud bolts 10 having different outer diameters of the shafts 10b are used properly, the stud bolts are as described above. 10 can be held properly. As a result, for the battery terminal 1, for example, it is not necessary to create the main body 20 for each stud bolt 10 having different outer diameters of the shaft 10b, and the outer diameters of the shaft 10b are different from each other in a common mold. Since a plurality of types of battery terminals 1 can be manufactured, the manufacturing cost can be suppressed.

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

The battery terminal according to the above-described embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims.

In the above description, the main body portion 20 is formed by integrally forming a pair of annular portions 20a and 20b, a bending connecting portion 20c, and a pair of holding plate-shaped portions 20d and 20e by press bending of a metal plate or the like. However, it is not limited to this. The main body portion 20 does not include, for example, a bending connecting portion 20c, and is an upper split body (annular portion 20a, holding plate-shaped portion 20d) forming an upper plate in the axial direction X and a lower split body forming a lower plate. It may have a two-layer split structure with (annular portion 20b, holding plate-shaped portion 20e), and may have a structure in which an upper split body and a lower split body configured as separate bodies are integrated.

In the above description, the adjusting unit 10c has been described as having the central axis C2 formed in a substantially columnar shape along the axis direction X (insertion direction), but the present invention is not limited to this. The adjusting portion 10c may be formed in a shape whose width is smaller than the width of the base portion and larger than the width of the shaft portion and is located in the insertion hole 20j. For example, the adjusting portion 10c may be formed in a substantially rectangular columnar shape or a substantially cross shape. 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, a shape for identification.

The battery terminal 201 according to the modified example shown in FIG. 8 is different from the battery terminal 1 described above in that the stud bolt 210 is provided instead of the stud bolt 10. The stud bolt 210 is different from the above-mentioned stud bolt 10 in that the identification symbol 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.

In the shaft portion 10b according to this modification, an identification symbol portion 210d that can be distinguished from other stud bolts is formed at the tip in the axial direction X. As an example, the identification symbol portion 210d shown in FIG. 8 is formed as a substantially circular recess at the tip of the shaft portion 10b. The shape of the identification symbol portion 210d is appropriately different depending on, for example, the outer diameter of the shaft portion 10b of the stud bolt 210 on which the identification symbol portion 210d is provided (for example, a substantially double circle shape, a substantially triangular shape, abbreviated). (Square shape, etc.). With this configuration, the battery terminal 201 has a plurality of battery terminals 201 to which stud bolts 210 having different outer diameters of the shaft portions 10b are applied to the common main body portion 20, depending on the outer diameter of the shaft portion 10b. It can be easily distinguished from each other.

In the above description, the adjusting unit 10c has been described as assuming that the surface 10ca is slightly retracted along the axial direction X with respect to the contact surface 20da and is positioned within the insertion hole 20j, but the present invention is not limited to this.

The battery terminal 301 according to the modified example shown in FIG. 9 is different from the battery terminal 1 described above in that the stud bolt 310 is provided instead of the stud bolt 10. The stud bolt 310 is different from the above-mentioned stud bolt 10 in that the adjusting portion 310c is provided 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 unit 310c according to this modification has a thickness tc along the axial direction X different from that of the adjustment unit 10c described above. Other configurations of the adjusting unit 310c are substantially the same as those of the adjusting unit 10c described above. Here, the adjusting 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, in the adjusting portion 310c, the surface 310ca on the tip end side of the axial direction X is substantially aligned with the contact surface 20da of the holding plate-shaped portion 20d of the holding portion 22 with the connection terminal T with respect to the axial direction X. That is, the surface 310ca of the adjusting unit 310c is located in the same plane as the contact surface 20da. With this configuration, the battery terminal 301 can use not only the contact surface 20da but also the surface 310ca of the adjusting portion 310c as a conduction surface with the connection terminal T, so that a relatively wide contact area with the connection terminal T is secured. can do. As a result, the battery terminal 301 can secure better conduction performance.
