  However, in the conventional electric component fixing structure as described in Patent Document 1, an object to be fixed (fusible link) is fixed to a protrusion (electrode post) of an object to be fixed (battery). Then, the entire load of the object to be fixed acts on the protrusion, and the load on the protrusion becomes large. Therefore, in addition to such a fixing structure, a configuration that reduces the load on the fixed object by adopting a fixing structure in which the fixed object is locked to the fixed object by the locking member may be considered. At this time, when the locking member is hook-shaped and a locking portion capable of locking the locking member is provided on the fixed object, there is a possibility that a tolerance may occur in the relative position between the locking member and the locking portion. . Therefore, the locking member may interfere with other members (for example, ribs for reinforcing the locking portion) in the fixed object, and the locking member cannot be locked by the locking portion. It is done.

  An object of the present invention is to provide an object to be fixed that can be locked to an object to be fixed, a fusible link, and a structure for fixing the object to be fixed to the object to be fixed, while accommodating tolerances.

Supported by the post 14.

  In the base body 23, a metal locking member 30 is provided on the front wall portion 234 on the side away from the connection member support portion 236 (lower left side in FIG. 2). As shown in FIGS. 4 and 5, the locking member 30 has a first arm part 31 and a second arm part 32 extending so as to cross each other, and is formed to be elastically deformable in an overall L shape. It is integrally formed from a metal plate material by punching and bending. The first arm portion 31 is located between the pair of rib portions 235 of the base body 23, extends along the second upper surface portion 152, and an end portion on the side away from the second arm portion 32 is a front wall portion 234. It is attached to the base body 23 by being inserted through the formed insertion hole 234A. The width of the first arm 31 is slightly smaller than the distance (inner dimension) between the pair of ribs 235 in the base body 23, and the position of the first arm 31 can be adjusted in the left-right direction (width) between the ribs 235. It is configured. The second arm portion 32 is provided extending below the lower end edge 18 of the side surface portion 16 of the upper case 12.

  A bent portion 33 that is bent away from the side surface portion 16 of the upper case 12 is formed at the lower end portion of the second arm portion 32, and the upper portion of the bent portion 33 is bent toward the upper case 12 side. A locked portion 34 that is locked to the lower end edge 18 of the side surface portion 16 is formed.

  The locked portion 34 is formed by cutting and raising the second arm portion 32, bent to the upper case 12 side, and bent upward (first arm portion 31 side) to have an L-shaped cross section. That is, the locked portion 34 has a hook-like hooking portion 35 whose end is folded back. Further, as shown in FIGS. 6 and 7, the hooking portion 35 is formed to be wide and formed in two mountain shapes whose front end portions are aligned in the width direction, that is, two apex portions 351 and 352, And inclined portions 353 and 354 that sandwich the apex portion 351 and are inclined with respect to the folding direction (the vertical direction in FIG. 6), and inclined portions 355 and 356 that sandwich the apex portion 352 and are inclined with respect to the folding direction. doing. Furthermore, a valley portion 357 is formed between two peaks arranged in the width direction, that is, between the two vertex portions 351 and 352. In addition, a front-end | tip part points out the whole part bent upwards.

  In the state where the base body 23 is installed on the upper case 12, the above-described locking member 30 is locked by hooking the hook portion 35 of the locked portion 34 on the lower edge 18 of the side surface portion 16 of the upper case 12. It has become so. When the base body 23 is attached to the battery 10, the bent portion 34 is pushed down so that the locked portion 34 is positioned below the lower end edge 18 in FIG. Lock.

  At this time, when the locked portion 34 does not interfere with the rib 19, the locked portion 34 is locked to the lower edge 18 as it is. On the other hand, when the locked portion 34 interferes with the rib 19, the inclined portions 353 to 356 abut against the rib 19, the entire locking member 30 moves in the width direction, and the position is adjusted between the rib portions 235. That is, when the rib 19 is positioned on the left side of the left apex portion 351 in FIG. 6, the locking member 30 is positioned so that the locked portion 34 is positioned on the right side of the rib 19 by the left inclined portion 353. When the rib 19 moves and is positioned between the apex portions 351 and 352, the locking member 30 is positioned so that the rib 19 is positioned in the valley portion 357 by the inclined portions 354 and 355 between the apex portions 351 and 352. When the rib 19 is positioned on the right side of the right apex portion 352, the locking member 30 is moved by the right inclined portion 356 so that the locked portion 34 is positioned on the left side of the rib 19. To do.

  On the other hand, when removing the base body 23 from the battery 10, the bent portion 34 is held down to release the locked portion 34 by the lower edge 18.

  According to this embodiment, there are the following effects. That is, since the locked portion 34 has a hook-shaped hook portion 35 and the hook portion 35 is formed in a mountain shape, there is a tolerance between the locked portion 34 and the lower end edge 18 in the width direction. Even when the locked portion 34 is generated and interferes with the rib 19, the locking member 30 is moved by causing the rib 19 to abut against the inclined portions 353 to 356 to move the locking member 30. The relative position of the stop member 30 can be adjusted. Furthermore, a common locking member 30 can be used for batteries having different rib 19 formation positions, and fuse units 20 having different installation positions and dimensions in the width direction, thereby reducing costs.

  Further, since the valley portion 357 is formed between the vertex portions 351 and 352, when the rib 19 is positioned between the vertex portions 351 and 352, the rib 19 is sandwiched by the inclined portions 354 and 355, thereby locking in the width direction. The movement of the member 30 is restricted, and rattling in the width direction can be suppressed.

  Further, since the bent portion 33 is formed in the second arm portion 32, the bent portion 33 is operated when the locking member 30 is locked or released from the lower end edge 18. And operability can be improved.

  In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.

  For example, in the above embodiment, the fuse unit 20 has the unit main body 22 and the base body 23 as separate bodies. However, as shown in FIG. 8, the unit main body 42 and the base body 43 are integrally molded. The unit 40 may be used. According to such a configuration, it is not necessary to assemble the unit main body and the base body, and the number of assembling steps can be reduced.

  Moreover, in the said embodiment, although the hook part 35 shall have the inclination parts 353-356 which pinch | interpose the vertex parts 351 and 352, the front-end | tip part is formed in the mountain shape, and it has at least one side of the vertex part. It suffices if an inclined portion is formed, and the other side of the apex portion may extend in the folding direction.

  Moreover, in the said embodiment, although the hook part 35 shall be formed in two mountain shape arranged in the width direction, according to the width | variety etc. of a corresponding rib, the hook part has one whole tip part. It may be formed in a mountain shape (having one apex portion), or may be formed in three or more mountain shapes (having three or more apex portions).

  Moreover, in the said embodiment, although it was set as the fixed structure of the electrical component which fixes the fuse unit 20 as a to-be-fixed object (fusible link) with respect to the battery 10 as a to-be-fixed object, it becomes a fixed object by the latching member. For example, a bus bar unit that does not include a fuse as an electric component may be fixed to the battery, and the fixed object and the fixed object are not electric components. May be.
