In this example, two battery connection units 20 are provided. Hereinafter, if necessary, one of the two battery connection units 20 will be referred to as a first battery connection unit 20A, and the other of them will be referred to as a second battery connection unit 20B. In this power supply connection system 1, the electronic component 21 of the first battery connection unit 20A is laminated on the second terminal member 12, and the electronic component 21 of the second battery connection unit 20B is laminated on the electronic component 21. It is laminated. In FIG. 1, the female screw member 27 related to the first battery connection unit 20A is not shown, and the terminal 115 related to the second battery connection unit 20B is not shown.

The power supply connection system 1 includes a holding member 30 that houses the battery terminal 10 and holds the battery connection unit 20 (FIGS. 1 and 3). The holding member 30 is formed of an insulating material such as a synthetic resin.

The holding member 30 has a through hole 32 through which the battery post 101 is inserted (FIG. 3). The holding member 30 is installed on the first surface 100a of the battery 100 so that the battery post 101 is inserted into the through hole 32 thereof. The first terminal member 11 of the battery terminal 10 is placed on the holding member 30 while inserting the battery post 101, and is housed in the accommodating portion 33 formed of a surrounding wall or the like. The power connection system 1 includes a rotation regulating member 35 that regulates the rotation of the battery post 101 around the axis of the battery terminal 10. The rotation restricting member 35 is formed of an insulating material such as a synthetic resin, and has a through hole 35a through which the battery post 101 is inserted. The rotation restricting member 35 is arranged so as to sandwich the battery terminal 10 with the holding member 30, and is attached to the holding member 30.

The holding member 30 holds the first battery connection unit 20A in a state where the electronic component 21 is laminated on the second terminal member 12. A holding mechanism (not shown) is provided between the support member 22 and the holding member 30 of the first battery connection unit 20A to hold the first battery connection unit 20A so as not to come off from the holding member 30. .. The holding mechanism is, for example, a locking mechanism that engages each other by hooking one claw portion on the other. The second battery connection unit 20B is held by the holding member 30 in a state in which the electronic component 21 is laminated on the electronic component 21 of the first battery connection unit 20A. A holding mechanism (not shown) is provided between the support member 22 and the holding member 30 of the second battery connection unit 20B to hold the second battery connection unit 20B so as not to come off from the holding member 30. .. The holding mechanism may be configured in the same manner as that related to the first battery connection unit 20A.

The power connection system 1 includes a fixing structure 40 for fixing the holding member 30 to the battery 100 (FIG. 1). The fixing structure 40 is fixed to the battery 100 by using a fixing tool 41 attached to the holding member 30, and includes a leaf spring member 50 and a connecting member 60 as the fixing tool 41 (FIGS. 5 to 5). 8).

The leaf spring member 50 has an elastic arc-shaped and plate-shaped arc-shaped elastic body 51, and is formed by using a metal plate as a base material. The leaf spring member 50 is arranged so that the inner peripheral surface side of the arc-shaped elastic body 51 faces the battery 100 side when the holding member 30 is installed on the first surface 100a of the battery 100.

The leaf spring member 50 has a locking portion 52 at one end in the circumferential direction of the arcuate elastic body 51. The locking portion 52 is a portion that is hooked on the locked portion 102 of the battery 100 when the holding member 30 is fixed to the battery 100 (FIGS. 9 and 10), and the leaf spring member 50 is hooked on the locked portion 102. To lock. The locking portion 52 of this example is formed as a hook shape bent from one end in the circumferential direction to the inner peripheral surface side of the arc-shaped elastic body 51. The leaf spring member 50 of this example is provided with two locking portions 52 (FIG. 6). When the holding member 30 is fixed to the battery 100, the leaf spring member 50 rotates the locking point between the locking portion 52 and the locked portion 102 as a virtual rotation axis.

Here, the locked portion 102 is provided on the second surface 100b of the battery 100. The locked portion 102 of this example is projected from the first projecting body 102a projecting from the second surface 100b and the end portion of the first projecting body 102a on the projecting direction side toward the lower surface side of the battery 100. It has a second projecting body 102b and. The locking portion 52 is inserted into the gap between the second projecting body 102b and the second surface 100b and hooked on the second projecting body 102b.

The leaf spring member 50 is moved between a free position before the locking portion 52 is locked to the locked portion 102 and a fixed position after the holding member 30 is fixed to the battery 100. 11 to 13 show a fixed structure 40 when the leaf spring member 50 is in a free position. 14 to 16 show a fixed structure 40 when the leaf spring member 50 is in the fixed position. The connecting member 60 is responsible for the movement of the leaf spring member 50.

The connecting member 60 connects the leaf spring member 50 to the holding member 30. The connecting member 60 rotatably supports the other end of the arcuate elastic body 51 in the circumferential direction between the free position and the fixed position, and is rotatably supported by the holding member 30. The connecting member 60 of this example is a bent wire rod made of metal or the like, and has a set of shaft portions 61, 62 in which the axes are arranged in parallel at intervals from each other (FIGS. 5 to 8). In the connecting member 60, one shaft portion 61 serves as the first rotating shaft 71 described later, and the other shaft portion 62 serves as the second rotating shaft 81 described later. The connecting member 60 of this example is bent into a square.

In this fixed structure 40, a first rotation mechanism 70 is provided between the leaf spring member 50 and the connecting member 60, and a second rotation mechanism 80 is provided between the connecting member 60 and the holding member 30 (. FIG. 10).

The first rotation mechanism 70 enables relative rotation between the other end of the arcuate elastic body 51 in the circumferential direction and the connecting member 60. The first rotation mechanism 70 has a first rotation shaft 71 parallel to the axis of the arcuate elastic body 51 (FIGS. 5 to 8). In this example, the shaft portion 61 of the connecting member 60 is a first rotating shaft 71, and a bearing 72 that pivotally supports the first rotating shaft 71 is provided at the other end of the arcuate elastic body 51 in the circumferential direction. Here, the bearing 72 is formed at the other end of the arcuate elastic body 51 by bending the other end of the arcuate elastic body 51 so as to wind around the first rotating shaft 71.

The second rotation mechanism 80 enables relative rotation between the connecting member 60 and the holding member 30. The second rotation mechanism 80 has a second rotation shaft 81 parallel to the first rotation shaft 71 (FIGS. 5 to 8). In this example, the shaft portion 62 of the connecting member 60 is used as the second rotating shaft 81, and the bearing 82 that pivotally supports the second rotating shaft 81 is provided on the holding member 30 (FIG. 10). The holding member 30 is provided with a groove portion as a bearing 82 into which the second rotating shaft 81 is rotatably fitted.

In the connecting member 60, the movement of the second rotating shaft 81 with respect to the holding member 30 in the radial direction is restricted, and the second rotating shaft 81 becomes the center of rotation in the fixture 41. Therefore, in the connecting member 60, the first rotating shaft 71 revolves around the axis of the second rotating shaft 81 while rotating on its own axis.

In this fixed structure 40, the operator applies a pressing force from the outer peripheral surface side to the inner peripheral surface side of the arcuate elastic body 51 at a free position to lock the locking portion 52 of the leaf spring member 50 of the battery 100. By locking the locked portion 102 and further applying a pressing force from the locked portion 102, the leaf spring is rotated relative to each other between the leaf spring member 50 and the connecting member 60 and between the connecting member 60 and the holding member 30. The member 50 rotates about the locking point, and the leaf spring member 50 moves to the fixed position.

In the fixed structure 40, the connecting member 60 is formed as follows so as not to rotate the leaf spring member 50 in the opposite direction at the fixed position. In the connecting member 60, the curvature of the arc-shaped elastic body 51 becomes smaller during the movement of the leaf spring member 50 from the free position to the fixed position, and the curvature of the arc-shaped elastic body 51 when moving to the fixed position is during the movement. The arcuate elastic body 51 is deformed so as to be larger than the minimum curvature and smaller than the curvature at the free position. The connecting member 60 is formed so that the distance between the first rotating shaft 71 and the second rotating shaft 81 enables the deformation of the arc-shaped elastic body 51. Further, in the connecting member 60, the first rotating shaft 71 gets over the second rotating shaft 81 during the movement from the free position to the fixed position, and as the connecting member 60 gets over the second rotating shaft 81, the curvature of the arcuate elastic body 51, which is the smallest, becomes large. It is desirable to form it so that it becomes. As a result, the leaf spring member 50 at the fixed position exerts a pressing force on the battery 100 from one end (locking portion 52 and its surroundings) in the circumferential direction on the inner peripheral surface side of the arcuate elastic body 51. A pressing force is applied to the holding member 30 from the other end (bearing 72) in the circumferential direction via the connecting member 60. Therefore, the leaf spring member 50 at the fixed position is locked on the inner peripheral surface side of the arc-shaped elastic body 51 with the assembled body of the battery 100 and the holding member 30 sandwiched between both ends in the circumferential direction. Rotation in the direction is suppressed. Therefore, the fixed structure 40 can maintain the fixed state of the power supply connection system 1 to the battery 100. Further, the fixed structure 40 can suppress the rotation of the power supply connection system 1 around the axis of the battery post 101. Furthermore, the fixing structure 40 simply applies a pressing force to the leaf spring member 50 of the fixture 41 attached to the holding member 30, and causes the power supply connection system 1 including the holding member 30 to the battery 100. It can be easily fixed.

By the way, in the power supply connection system 1, the holding member 30 is fixed to the battery 100 by improving the workability when the operator operates the fixture 41 (leaf spring member 50 and connecting member 60). It can be easily smoothed, and the workability of assembling to the battery 100 can be improved. Therefore, in the fixed structure 40 of the present embodiment, when the leaf spring member 50 is moved from the free position to the fixed position on the outer peripheral surface of the arcuate elastic body 51 so that the operator can at least tactilely recognize it. The operation area 90 on which the operator applies a pressing force is provided in the area 90. The operation area 90 is provided with an operation unit 91 as an operation point on which the pressing force is applied (FIGS. 5 to 8).

The operating region 90 is set on one end of the arcuate elastic body 51 in the circumferential direction when a pressing force from the outer peripheral surface side to the inner peripheral surface side of the arcuate elastic body 51 is applied at a free position of the leaf spring member 50. The provided locking portion 52 is arranged at a position where it can be hooked on the locked portion 102 of the battery 100 and the leaf spring member 50 can be moved to a fixed position while being hooked. For example, in the fixture 41, after the locking portion 52 of the leaf spring member 50 is hooked on the locked portion 102 of the battery 100, the first rotating shaft 71 of the connecting member 60 gets over the second rotating shaft 81. It is necessary to apply a pressing force to the outer peripheral surface of the arcuate elastic body 51. For this reason, it is desirable that the pressing force pushes the bearing 72 at the other end of the arc-shaped elastic body 51 toward the upper surface side of the battery 100 while bringing the inner peripheral surface side of the arc-shaped elastic body 51 closer to the battery 100. Therefore, the operating region 90 has an outer peripheral surface thereof, for example, in the arc-shaped elastic body 51 when the locking portion 52 is hooked on the locked portion 102 of the battery 100 so that such a pressing force can be applied. It is arranged closer to the locking portion 52 than the apex (the portion farthest from the battery 100) (FIG. 9). However, the pressing force needs to act at a position where the leaf spring member 50 is rotated around the locking point between the locking portion 52 and the locked portion 102. Therefore, the operation region 90 is set closer to the bearing 72 than the locking portion 52 in the range of the previous arrangement in order to generate the rotational torque required for the rotational operation of the leaf spring member 50 by the pressing force. It is desirable to arrange so that a moment arm of rotational torque is provided.

For example, here, the following fixture 41A is shown as a specific example of the fixture 41 (FIGS. 5 to 8). The fixture 41A is obtained by attaching the following leaf spring member 50A, which is a specific example of the leaf spring member 50, to the connecting member 60. In the leaf spring member 50A, as a specific example of the operation portion 91, a through hole for communicating the outer peripheral surface side and the inner peripheral surface side of the arc-shaped elastic body 51 is provided. In the operation region 90 of the leaf spring member 50A, the through hole is used as the operation portion 91A. The operation unit 91A has a size and shape that can be recognized by an operator who touches the outer peripheral surface of the arcuate elastic body 51 with at least fingers. The operating portion 91A shown here is formed in the central portion of the arcuate elastic body 51 in the circumferential direction. The operation unit 91A can also be visually recognized by the operator.

As described above, in the power supply connection system 1, the operator can easily recognize the action point (operation point) of the pressing force on the leaf spring member 50 (50A), and the operation unit 91 (operation point) as the operation point can be easily recognized. The fixture 41 (41A) is locked between the holding member 30 and the battery 100 by simply applying a pressing force to the 91A) and its surroundings, and is fixed to the battery 100 together with the holding member 30. Therefore, the power connection system 1 has improved workability for assembling to the battery 100 as compared with the conventional case, so that the assembling work can be performed easily and accurately.

As the fixture 41, the following fixture 41B can also be mentioned (FIGS. 17 to 20). The fixture 41B is obtained by attaching the following leaf spring member 50B, which is a specific example of the leaf spring member 50, to the connecting member 60. In the leaf spring member 50B, as a specific example of the operation portion 91, a bulging portion bulging from the outer peripheral surface of the arc-shaped elastic body 51 is provided. In the operation region 90 of the leaf spring member 50B, the bulging portion is used as the operation portion 91B. The operation unit 91B has a size and shape that can be recognized by an operator who touches the outer peripheral surface of the arcuate elastic body 51 with at least fingers. The operation unit 91B shown here is formed in the central portion of the arcuate elastic body 51 in the circumferential direction. The operation unit 91B can also be visually recognized by the operator. Further, instead of such a bulging portion, the operating portion 91B may use a recess in which the outer peripheral surface of the arc-shaped elastic body 51 is recessed toward the inner peripheral surface side. Even if the power supply connection system 1 is replaced with such a fixture 41B, the workability of assembling to the battery 100 can be improved as in the above example.

Here, when the fixture 41B uses a bulge as the operation portion 91B, the bulge may be formed as follows. The bulging portion is formed so as to be recessed toward the inner peripheral surface side of the arcuate elastic body 51 when the pressing force is continuously applied after moving the leaf spring member 50B to the fixed position. The bulging portion is formed so that the force F1 required for denting is larger than the force F2 required for moving the leaf spring member 50B from the free position to the fixed position (F1> F2). For example, in order to establish such a force relationship, the bulging portion is formed to be thinner than the plate thickness of the surrounding arc-shaped elastic body 51 so that it can be recessed when a force F2 is applied. As a result, the power connection system 1 not only has the effect of improving workability until it is fixed to the battery 100 as in the above example, but also has a dented deformation of the bulging portion as the operating portion 91B, and at least the fingers. It is possible to make the operator recognize the completion of the fixing work by the tactile sensation. The operation unit 91B of this example can visually confirm the completion of the fixing work as well as visually confirm the dent. Therefore, the power supply connection system 1 in this case can further improve the workability of assembling to the battery 100.
