  According to the conventional example, since the stud bolt 102 is provided on the fixing member 100, the cost increases. Further, the capacitor 105 is generally heavy for its size. For this reason, when the capacitor 105 is temporarily placed and when the nut 120 is tightened, the bracket 110 moves with respect to the stud bolt 102, so that the thread of the stud bolt 102 may be crushed. Patent Document 1 does not describe anything regarding temporary placement of capacitors. An object of the present invention is to provide a capacitor mounting structure in which a capacitor can be temporarily placed without setting a stud bolt on a fixing member.

  The above-described object can be solved by the capacitor mounting structure of the present invention. 1st invention is the attachment structure of the capacitor | condenser which attaches the capacitor | condenser for an electrical noise removal to the fixing member of a vehicle body side, Comprising: One end part is attached to the said capacitor | condenser, and the other end part is fastened with the said fixing member with a volt | bolt A bracket-shaped latching portion is formed between one end and the other end of the bracket, and the other end of the bracket is on the opening side of the latching portion. And a connector support part that supports the connector of the capacitor is formed, and the hook part can be hooked to another member with the opening side of the hook part facing downward. The capacitor mounting structure is formed. According to this configuration, the capacitor can be attached to the fixing member by inserting the bolt into the bolt insertion hole of the bracket attached to the capacitor and tightening the bolt into the screw hole of the fixing member. By the way, when it is desired to temporarily place the capacitor on another member such as a fixing member during the capacitor mounting operation, the bracket hooking portion attached to the capacitor is hooked to the other member with the opening side facing downward. Thus, the capacitor can be temporarily placed. For this reason, a capacitor can be temporarily placed without setting a stud bolt on the fixing member.

  According to a second aspect of the present invention, in the first aspect of the present invention, a folded portion that is bent toward the side opposite to the opening side of the latching portion is formed at the end of the latching portion of the bracket on the capacitor side. This is a capacitor mounting structure. According to this configuration, when the capacitor is temporarily placed, when the bent portion that connects the hooking portion and the folded portion of the bracket comes into contact with the other member, the rotation of the bracket is restricted by the contact. For this reason, the fall of the capacitor | condenser accompanying the rotation can be suppressed.

  According to a third aspect, in the first or second aspect, the connector support portion of the bracket includes a base portion and an arm that extends in an inclined manner from the distal end portion of the base portion toward a direction away from the opening side of the latching portion. And a capacitor mounting structure. According to this configuration, when temporarily placing the capacitor on another member, it is possible to prevent the connector support portion of the bracket from becoming an obstacle.

  According to a fourth invention, in the second invention, the connector support portion of the bracket includes a base portion, and an arm portion that extends in an inclined manner from a distal end portion of the base portion toward a direction away from the opening side of the latching portion. And the bent portion that connects the hook portion and the folded portion, and the bent portion that connects the base portion of the connector support portion and the arm portion at the opposing positions. The capacitor mounting structure is arranged so as to narrow the opening width of the capacitor. According to this configuration, the connector support portion of the bracket includes the base portion and the arm portion that extends in an inclined direction from the distal end portion of the base portion toward the opening side of the latching portion. When this is temporarily placed on another member, it is possible to prevent the connector support portion of the bracket from interfering. In addition, the range in which the bracket can be hooked to other members is regulated by the bent portion that connects the hook portion and the folded portion, and the bent portion that connects the base portion of the connector support portion and the arm portion. The bracket can be easily hooked to another member.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a capacitor mounting structure, FIG. 2 is a cross-sectional view, FIG. 3 is a perspective view showing exploded components, and FIG. 4 is a conceptual view showing a temporarily placed state of the capacitor. The orientation in FIGS. 1 to 3 is set for convenience of explanation, and does not limit the arrangement direction of the capacitor. However, the vertical direction corresponds to the vertical direction relative to the vehicle body, that is, the vertical direction.

  As shown in FIG. 3, the fixing member 10 is made of sheet metal and is installed in a vertical plate shape on the vehicle body, for example, the engine room side of the front fender 11. The plate thickness direction of the fixing member 10 is directed, for example, in the vehicle width direction (left-right direction) of the vehicle body. A circular through hole 12 that penetrates in the plate thickness direction is formed at the upper end of the fixing member 10. A nut 14 having a screw hole 15 is attached to the back surface, that is, the right side surface of the fixing member 10 by welding. The nut 14 is arranged coaxially with the axis of the through hole 12. The fixing member 10 is formed with an anti-rotation hole 17 penetrating in the plate thickness direction. The anti-rotation hole 17 is disposed near the lower portion of the through hole 12.

  The capacitor 20 is a capacitor for removing electrical noise, has a rectangular parallelepiped shape, and has a connector 22. The capacitor 20 (specifically, the capacitor body) and the connector 22 are connected via a lead wire 24. An insertion hole 26 penetrating in the horizontal direction (left-right direction) is formed in the upper end portion of the capacitor 20. The insertion hole 26 is formed in a long pore shape that lengthens the front-rear direction.

  A bracket 30 is attached to the capacitor 20. The bracket 30 is made of sheet metal, and has a base portion 32 extending in the horizontal direction (left-right direction). The plate thickness direction of the base portion 32 is directed in the vertical direction. The bracket 30 is attached to the capacitor 20 by inserting one end portion (left end portion) of the base portion 32 into the insertion hole 26 of the capacitor 20 by press fitting or the like. A portion inserted into the capacitor 20 in the base portion 32 is referred to as a capacitor mounting portion 33.

  At the other end portion (right end portion) of the base portion 32, an attachment portion 34 that is bent so as to rise upward is formed. The plate thickness direction of the attachment portion 34 is directed in the left-right direction. A circular bolt insertion hole 35 penetrating in the plate thickness direction is formed at the upper end portion of the attachment portion 34. The bolt insertion hole 35 corresponds to the screw hole 15 of the fixing member 10. The attachment portion 34 is formed with a rotation stop piece 36 protruding rightward by cutting and raising. The anti-rotation piece 36 is disposed near the lower portion of the bolt insertion hole 35 and corresponds to the anti-rotation hole 17 of the fixing member 10. Reinforcing pieces 38 that rise in a flange shape are formed by bending at both front and rear edge portions on the inner corner side of the bracket 30 including the base portion 32 and the attachment portion 34.

  A band-plate-like connector support portion 40 that protrudes leftward is formed at the upper end portion of the attachment portion 34, specifically, at the upper end portion of the front reinforcing piece 38. The thickness direction of the connector support portion 40 is directed in the front-rear direction. The connector support portion 40 includes a base portion 41 that protrudes leftward from the reinforcing piece 38 and an arm portion 42 that extends obliquely from the distal end portion of the base portion 41 toward the upper left. That is, the base 41 protrudes toward the left, which is the opening side of the latching portion 45 (which will be described later). The arm portion 42 extends in a direction away from the opening side of the latching portion 45, and the base portion 41 and the arm portion 42 are connected via an arc-shaped bent portion 43. The connector 22 of the capacitor 20 is attached to the arm portion 42.

  In the base portion 32 of the bracket 30, a recessed hooking portion 45 is formed in the remaining portion excluding the capacitor mounting portion 33. The latching portion 45 is formed in, for example, a U shape. The upper right end portion of the latching portion 45 is continuous with the attachment portion 34. The inside of the latching portion 45 is a recess that opens on the upper surface.

  As shown in FIG. 2, a folded portion 47 is formed between the end of the latching portion 45 on the capacitor 20 side, that is, between the latching portion 45 and the capacitor mounting portion 33. The folded portion 47 is bent toward the side opposite to the opening side of the latching portion 45, that is, toward the left, and is continuous with the capacitor mounting portion 33. The hooking portion 45 and the folded portion 47 are connected via an arcuate bent portion 48. The bent portion 48 of the base portion 32 and the bent portion 43 of the connector support portion 40 are arranged so as to narrow the opening width (width in the left-right direction) of the latching portion 45 at an opposing position. The hooking portion 45 is formed so as to be hookable on the fixing member 10 with the opening side facing downward, that is, with the bracket 30 turned upside down (see FIG. 4). At this time, the bracket 30 is disposed so as to intersect the fixing member 10 orthogonally in a plan view.

  Next, an example of a procedure for attaching the capacitor (the capacitor with the bracket 30) 20 to the fixing member 10 of the vehicle body will be described. First, the worker connects the connector 50 (see FIG. 4) of the wire harness arranged on the vehicle body side to the connector 22 of the capacitor 20. Thereby, forgetting to connect the connectors 22 and 50 can be suppressed.

  Subsequently, the worker temporarily places the capacitor 20 with the bracket 30 on the fixing member 10. That is, as shown in FIG. 4, the latching portion 45 of the bracket 30 of the capacitor 20 with the bracket 30 is latched on the fixing member 10 with the opening side facing downward, whereby the capacitor 20 is temporarily attached to the fixing member 10. Placed. Thereby, both hands of an operator can be made free. The fixing member 10 corresponds to “another member” in this specification.

  Next, the operator holds a hand-held screw tightening tool (not shown) with one hand, holds a bolt 53 (see FIG. 3) with the other hand, and sets the bolt 53 on a screwdriver tool screw screw. To do. And the capacitor | condenser 20 with the bracket 30 is picked up with a vacant hand, and the rotation prevention piece 36 of the bracket 30 is engaged with the rotation prevention hole 17 of the fixing member 10 (refer FIG. 2). In this state, the bolt 53 is tightened to the nut 14 of the fixing member 10, that is, the screw hole 15 through the bolt insertion hole 35 of the bracket 30 with a screw tightening tool. At this time, the bracket 30 is prevented from rotating because the rotation stopper piece 36 of the bracket 30 is engaged with the rotation stopper hole 17 of the fixing member 10. Thereby, the attachment of the capacitor 20 with the bracket 30 to the fixing member 10 is completed (see FIGS. 1 and 2). As the bolt 53, for example, a hexagonal bolt is used.

  As shown in FIG. 4, when the capacitor 20 with the bracket 30 is temporarily placed on the fixing member 10, the capacitor 20 with the bracket 30 is supported on the fixing member 10 in a well-balanced manner. The contact (collision) of the capacitor 20 with the fixing member 10 can be suppressed. In addition to the weight of the connectors 22 and 50, the wire harness may have a tensile force depending on the weight of the wire harness on the vehicle body side and the length of the wire harness.

  In addition, as illustrated in FIG. 5, the capacitor 20 with the bracket 30 may be temporarily placed on the fixing member 10 such that the bent portion 48 of the base portion 32 contacts the fixing member 10. In this case, when the bent portion 48 of the base portion 32 comes into contact with the fixing member 10, the rotation of the bracket 30 is restricted. For this reason, the fall of the capacitor | condenser 20 accompanying rotation of the bracket 30 can be suppressed. Moreover, when the capacitor | condenser 20 with the bracket 30 is temporarily set | placed, as shown in FIG. In this case, the bent portion 43 of the connector support portion 40 of the bracket 30 comes into contact with the fixing member 10 or the base portion 41 is caught by the fixing member 10. For this reason, the fall of the capacitor 20 can be suppressed.

  According to the mounting structure of the capacitor 20 described above, the bolt 53 is inserted into the bolt insertion hole 35 of the bracket 30 attached to the capacitor 20, and the bolt 53 is tightened into the screw hole 15 of the fixing member 10 to fix the capacitor 20. It can be attached to the member 10 (see FIGS. 1 and 2). By the way, when the capacitor 20 is temporarily placed on the fixing member 10 when the capacitor 20 is attached, the hooking portion 45 of the bracket 30 attached to the capacitor 20 is attached to the fixing member 10 with the opening side facing downward. It latches (refer FIG. 4). Thereby, the capacitor 20 can be temporarily placed. For this reason, the capacitor 20 can be temporarily placed without setting a stud bolt on the fixing member 10.

  Incidentally, the capacitor of the conventional example (see FIGS. 7 to 9) has no technical idea of hooking the bracket to the fixing member. Therefore, even if the bracketed capacitor is turned upside down to be hooked on another member, the capacitor 20 falls due to its own weight, and the capacitor cannot be hooked on the fixed member.

  Moreover, since it is not necessary to set a stud bolt in the fixing member 10, the structure by the side of the fixing member 10 can be simplified and cost can be reduced. In addition, even if the latching portion 45 of the bracket 30 slips off from the fixing member 10 due to vibration or the like in the temporarily placed state of the capacitor 20, the bent portion 43 of the connector support portion 40 of the bracket 30 contacts the fixing member 10. Or since the base 41 is caught by the fixing member 10, the fall of the capacitor | condenser 20 can be suppressed (refer FIG. 6). Further, since the connector support portion 40 also serves as a member for preventing the capacitor 20 from falling, the shape of the bracket 30 can be simplified.

  Further, a folded portion 47 that is bent toward the side opposite to the opening side of the latching portion 45 is formed at the end of the latching portion 45 of the bracket 30 on the capacitor 20 side. Therefore, when the capacitor 20 is temporarily placed, when the bent portion 48 connecting the hooking portion 45 and the folded portion 47 of the bracket 30 contacts the fixing member 10, the rotation of the bracket 30 is restricted by the contact. (See FIG. 5). For this reason, the fall of the capacitor | condenser 20 accompanying the rotation can be suppressed.

  Further, the connector support portion 40 of the bracket 30 includes a base portion 41 and an arm portion 42 that extends in an inclined manner from the distal end portion of the base portion 41 toward the direction away from the opening side of the latching portion 45. Therefore, when the capacitor 20 is temporarily placed on the fixing member 10, it is possible to prevent the connector support portion 40 of the bracket 30 from interfering.

  Further, the bent portion 48 of the base portion 32 and the bent portion 43 of the connector support portion 40 are arranged so that the opening width of the latching portion 45 is narrowed at an opposing position. Therefore, the range in which the bracket 30 can be hooked with respect to the fixing member 10 is restricted by the bent portion 48 of the base portion 32 and the bent portion 43 of the connector support portion 40. Thereby, the bracket 30 can be easily hooked on the fixing member 10.

  Further, between the mounting portion 34 of the bracket 30 and the fixing member 10, there is provided a detent means including a detent hole 17 and a detent piece 36 that can be engaged with each other. Therefore, the bracket 30 can be prevented from rotating around the fixing member 10 by the engagement between the rotation preventing hole 17 and the rotation preventing piece 36.

[Other Embodiments] The present invention is not limited to the embodiments and can be modified without departing from the gist of the present invention. For example, the bolt 53 may be a component having a male screw in addition to a hexagon bolt. In the embodiment, the nut 14 having the screw hole 15 is attached to the fixing member 10, but the screw hole may be formed in the fixing member 10 itself. In the embodiment, the fixing member 10 is used as the other member. However, if there is a member capable of temporarily placing the capacitor 20 in the vicinity of the attachment portion of the capacitor 20, the member may be used as the other member.
