As shown in FIGS. 4 and 5, the extension portion 32 is formed with an inclined surface 34 that is inclined upward to the right or upward to the left so as to approach the axis z1 from the lower side to the upper side when viewed from the front side. .. Further, as shown in FIG. 1, a boss portion 35 which is widened in a substantially U shape from the inside to the outside is formed in the upper center of the inclined surface 34 in the front-rear direction. As shown in FIGS. 2 and 3, the position of the boss portion 35 corresponds to the position through which the screw portion 51 is inserted with the bolt 50 attached. Further, the boss portion 35 is formed so as to project outward from between the leg portions 42 adjacent to each other in the front-rear direction with the slope member 40 assembled to the fixing portion 31.

The extension portion 32 has elasticity, and elastically moves left and right with the portion on the back side of the electrode fitting portion 21 as the base end portion. A bent portion 33 in which the end portion 36 is bent at a substantially right angle toward the left is formed at the front end of the extending portion 32 on the right side. The bent portion 33 extends to a position where the end portion 36 is close to the end portion of the inclined surface 34 on the front side of the extending portion 32 on the left side. The bent portion 33 is bent so that the length in the left-right direction covers the inner peripheral surface 321 inside the extending portion 32 from the front side.

As shown in FIG. 1, the slope member 40 is attached so as to cover the battery post terminal 10 from above the fixed portion 31. The slope member 40 includes a substantially square top surface portion 41, four leg portions 42 extending downward from each of the four corner portions of the top surface portion 41, and an insertion hole 411 provided in the central portion of the top surface portion 41. And have. The length of the side of the top surface portion 41 is formed so that the side in the front-rear direction is shorter than the side in the left-right direction. A screw portion 51 of a bolt 50, which will be described later, is inserted into the insertion hole 411. The four legs 42 are symmetrically arranged in the front-rear direction and left-right with respect to the insertion hole 411, and the distance between the legs 42 in the front-rear direction is narrower than the distance between the legs in the left-right direction. Further, the upper surface of the top surface portion 41 is formed in a flat shape so that the nut 60 can be stably tightened.

As shown in FIGS. 4 and 5, slopes 421 are formed on the left and right inside of the legs 42, respectively. The slope 421 is formed at the same inclination angle as the inclined surface 34 of the left and right extension portions 32, so that the inclined surface 34 and the slope 421 come into contact with each other in a state where the slope member 40 is assembled to the fixed portion 31. Become.

The lower end of the leg portion 42 abuts on the upper surface of the head 52 of the bolt 50 in a state where the nut 60 is completely tightened. That is, the length of the leg portion 42 is determined in relation to the tightening torque when the nut 60 is tightened, and overtorque is prevented by tightening until the four leg portions 42 abut. I am doing it.

Further, the legs 42 of the slope member 40 are arranged at intervals along the outer circumference of the screw portion 51, centering on the screw portion 51 of the bolt 50 when the state in which the slope member 40 is attached is viewed from the vertical direction. , They are arranged substantially evenly and in a well-balanced manner so as to surround the outside of the screw portion 51.

As shown in FIG. 1, the bolt 50 is composed of a screw portion 51 extending in the vertical direction and a head portion 52 located below the screw portion 51. The threaded portion 51 includes a male threaded portion 511 in which a thread is formed in a predetermined length range from the tip portion facing upward, a stepped portion 513 as a regulating member for restricting the movement of the slope member 40, and a male. A small diameter portion 512 provided between the screw portion 511 and the step portion 513 is provided. In the bolt 50, the small diameter portion 512 and the step portion 513 function as a regulating member that regulates the movement of the slope member 40 in the axis z1 direction. The bolt 50 is a so-called stepped bolt in which a stepped portion 513 having no thread is provided in a predetermined length range on the base end side of the threaded portion 51, that is, on the head 52 side.

Next, the operation of the fixed structure 1 of the battery post terminal in the first embodiment will be described.

In the fixing structure 1 of the battery post terminal, the state before fastening the nut 60 is a state in which the slope member 40 is placed on the fixing portion 31 as shown in FIGS. 2 and 4. The slope 421 of the slope member 40 is in surface contact with the inclined surface 34 of the fixing portion 31. Further, the bolt 50 is inserted from the lower side of the fixing portion 31, and the screw portion 51 passes through the space of the inner peripheral surface 321 of the left and right extension portions 32 (more specifically, between the left and right boss portions 35) and slopes. It is inserted into the insertion hole 411 of the member 40 and temporarily tightened with a nut 60.

The position of the slope member 40 in the left-right direction is regulated by the contact between the slope 421 and the inclined surface 34. Further, the position in the front-rear direction is regulated by the inner side surface of the slope member 40 in the front-rear direction and the boss portion 35 of the fixing portion 31 in contact with each other. Further, the position of the slope member 40 in the front-rear direction is also regulated by the inner side surface of the leg portion 42 in the front-rear direction and the boss portion 35. The position of the bolt 50 is regulated by the contact between the outer peripheral surface of the slope member 40 in the left-right direction and the upper surface of the head 52.

When the nut 60 is tightened from the upper side of the slope member 40 from the state shown in FIGS. 2 and 4, the slope member 40 has the left and right surfaces of the slope 421 and the inclined surface 34 as shown in FIGS. 3 and 5. While being guided by the contact, it moves in the axis z1 direction, specifically, in the lower −z direction (tightening direction of the bolt 50, see FIG. 5). Further, the slope 421 presses the inclined surfaces 34 of the left and right extension portions 32 inward + x direction or −x direction (see FIG. 5) by moving in the axis z1 direction. As a result, the inner peripheral surface 321 of the left and right extension portions 32 is elastically deformed inward so as to narrow the distance in the left-right direction, and the battery post in the inner peripheral surface 22 of the electrode fitting portion 21 is tightened and fixed.

Since the inclined surface 34 and the slope 421 press the extension portion 32 while contacting each other, the fastening force of the nut 60 is stably transmitted to the extension portion 32, and the extension portion 32 is pressed in a well-balanced manner. ..

The legs 42 are arranged so as to surround the outside of the screw portion 51 by arranging the battery post terminal 10 at intervals along the outer circumference of the screw portion 51 around the screw portion 51 of the bolt 50 when the battery post terminal 10 is viewed from the vertical direction. Since they are arranged substantially evenly, the left and right extension portions 32 are pressed inward with substantially even force. As a result, even if a force acts on the screw portion 51 after the bolt 50 and the nut 60 are fastened from multiple directions, uniform fixing strength can be ensured in any direction.

In the bolt 50, the slope member 40 moves in the axis z1 direction, specifically, in the lower −z axis direction by the male screw portion 511 of the screw portion 51. Specifically, in the bolt 50, the nut 60 screwed from the tip side of the screw portion 51 to the male screw portion 511 moves to the nut 60 by moving in the tightening direction of the male screw portion 511, that is, in the −z1 direction. The top surface portion 41 of the in contacting slope member 40 is pressed, and the slope member 40 moves in the axis z1 direction. Since the male screw portion 511 is formed in a predetermined length range from the tip end portion of the screw portion 51, the nut 60 and the slope member 40 move in the axis z1 direction within the length range of the male screw portion 511. ..

When the nut 60 reaches the base end side of the male screw portion 511, that is, the lower end, the nut 60 slips because the small diameter portion 512 and the step portion 513 of the screw portion 51 do not have threads that can be screwed with the nut 60. To do. In this way, the bolt 50 is formed with a small diameter portion 512 and a step portion 513, so that the nut 60 and the slope member 40 that can move together with the nut 60 are in the axis z1 direction, specifically, the lower −z axis. Regulate moving in the direction.

In the battery post terminal fixing structure 1 according to the first embodiment of the present invention, the small diameter portion 512 and the stepped portion 513 as regulating members for restricting the movement of the slope member 40 moving together with the nut 60 in the axis z1 direction are bolted 50. It is provided in the screw portion 51 of. According to the fixing structure 1 of the battery post terminal configured in this way, tightening is performed in a state where the specified torque is exceeded for the bolt 50 or rust preventive oil is attached between the bolt 50 and the nut 60. Even if it is broken, the position of the slope member 40 provided in the fixing structure 1 of the nut 60 and the battery post terminal in the axis z1 direction is lowered more than necessary to prevent the battery post terminal from being deformed more than necessary. be able to.

Although the fixed structure 1 of the battery post terminal according to the first embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are made based on the technical idea of the present invention. And can be changed.

For example, in the first embodiment, the bolt 50 has a small diameter portion 512 and a step portion 513 as a regulating member, but is not limited to this, and for example, a male screw portion 511 and a step portion 513. The small diameter portion 512 may not be provided between them, and the male screw portion 511 and the stepped portion 513 may be provided so as to be in contact with each other in the axis z1 direction.

Further, in the first embodiment, the bolt 50 is inserted from the lower side to the upper side, and the nut 60 is tightened on the upper side thereof. However, the nut and the bolt may be turned upside down. For example, a nut is fixed to the lower side by welding or the like, and a bolt is inserted from the upper side to fasten the bolt. Also with this structure, the bolt can be inserted in the vertical direction, and the operator can perform the fastening work on the upper side of the battery post terminal 10.

Further, in the first embodiment, the slope member 40 is attached so as to cover it from the upper side of the extension portion 32, but the slope member 40 may be attached from the lower side of the extension portion 32 so as to be pulled up. In this case, the inclined surface 34 of the extension portion 32 and the slope 421 of the slope member 40 may be formed upside down. Even with this structure, it is possible to receive forces acting in multiple directions in a well-balanced manner.

The collar 53 functions as a regulating member that regulates the movement of the slope member 40 in the axis z1 direction.

The collar 53 is a tubular member having an inner peripheral surface having dimensions that allow the screw portion 51A to be inserted. One end of the collar 53 is adhered to the screw portion 51A and comes into contact with the upper surface of the head 52 provided on the base end side of the screw portion 51A. In this state, the other end 531 of the collar 53 is located on the upper side of the screw portion 51A in the axis z1 direction.

Next, the operation of the fixed structure 1A of the battery post terminal in the second embodiment will be described.

In the fixing structure 1A of the battery post terminal, the state before fastening the nut 60 is a state in which the slope member 40 is placed on the fixing portion 31 as shown in FIGS. 7 and 9. The slope 421 of the slope member 40 is in surface contact with the inclined surface 34 of the fixing portion 31. Further, the bolt 50 is inserted from the lower side of the fixing portion 31, and the screw portion 51 passes through the space of the inner peripheral surface 321 of the left and right extension portions 32 (more specifically, between the left and right boss portions 35) and slopes. It is inserted into the insertion hole 411 of the member 40 and temporarily tightened with a nut 60.

The position of the slope member 40 in the left-right direction is regulated by the contact between the slope 421 and the inclined surface 34. Further, the position in the front-rear direction is regulated by the inner side surface of the slope member 40 in the front-rear direction and the boss portion 35 of the fixing portion 31 in contact with each other. Further, the position of the slope member 40 in the front-rear direction is also regulated by the inner side surface of the leg portion 42 in the front-rear direction and the boss portion 35. The position of the bolt 50 is regulated by the contact between the outer peripheral surface of the slope member 40 in the left-right direction and the upper surface of the head 52.

Similar to the battery post terminal fixing structure 1 described above, the battery post terminal fixing structure 1A is obtained by tightening the nut 60 from the upper side of the slope member 40 from the states shown in FIGS. As shown in FIG. 10, the slope member 40 is guided by surface contact between the slope 421 and the inclined surface 34 on the left and right, and is guided in the axis z1 direction, specifically, the lower −z direction (the tightening direction of the bolt 50A). (See FIG. 10). Further, the slope 421 presses the inclined surfaces 34 of the left and right extension portions 32 inward + x direction or −x direction (see FIG. 10) by moving in the axis z1 direction. As a result, the left and right extension portions 32 are elastically deformed inward so as to narrow the distance in the left-right direction, and the battery post in the inner peripheral surface 22 of the electrode fitting portion 21 is tightened and fixed.

In the bolt 50A, the slope member 40 moves in the axis z1 direction, specifically, in the lower −z axis direction by the male screw of the screw portion 51A. Specifically, in the bolt 50, the nut 60 screwed from the tip side of the screw portion 51 to the male screw portion 511 comes into contact with the nut 60 by moving in the tightening direction of the screw portion 51A, that is, in the −z1 direction. The top surface portion 41 of the slope member 40 is pressed, and the slope member 40 moves in the axis z1 direction. Since the collar 53 is formed in a predetermined length range from the tip end portion of the screw portion 51, the nut 60 and the slope member 40 move in the axis z1 direction within the length range of the collar 53.

When the nut 60 reaches the other end 531 of the collar 53, the lower surface of the top surface 41 of the slope member 40 comes into contact with the other end 531 and the nut 60 and the slope member 40 move downward in the axis z1 direction.
