The capacitor body 31 is pressed by the elastic force of the arm 261 in contact with the extending direction (Z plus direction in FIG. 2). With this pressing force, the side surface of the capacitor body 31 is pressed against the contact portion 22 that faces the pressing portion 262 across the holding space 21.

  In addition, as shown in FIG. 3, the notch is provided in the bottom face 35 side of the capacitor body 31 in the contact portion 22. For this reason, the contact part 22 does not exist in area | region A3 facing the holding | suppressing 26. FIG. However, if the straight line that coincides with the central axis in the longitudinal direction of the capacitor body 31 in the state where the resin case 2 is holding the capacitor body 31 (the straight line extending in the X direction in FIG. 3) is the holding axis line, the pressing portion 262 is The capacitor main body 31 comes into contact with the contact portion 22 at a position that coincides with the position in the holding axis direction (direction in which the holding axis extends) that is in contact with the capacitor main body 31, that is, the area A1 and the area A2 on both sides of the area A3. Therefore, the contact portion 22 contacts the side surface of the capacitor body 31 and the pressing portion 262 contacts the side surface of the capacitor body 31 in the same plane orthogonal to the holding axis.

  As shown in FIG. 2, the resin case 2 is provided with a pair of copper bars 41 as electrode terminal portions. Each of the pair of copper bars 41 is in contact with the distal end side of the bent portion 34 of the pair of leads 32 in a state where the resin case 2 holds the capacitor body 31.

Has been. Further, an opening S <b> 2 is formed in a region sandwiched between the bridge 25 and the presser 26, the pair of copper bars 41, and the pair of side walls 24.

  The procedure for holding the capacitor 3 in the electronic device 1 described above, that is, the procedure for holding the capacitor main body 31 in the resin case 2 as shown in FIG. 2 will be described below with reference to FIGS.

  First, the capacitor 3 is moved in the Z plus direction from below the opening S1 as shown in FIG. 4, and the side surface of the capacitor body 31 is brought into contact with the lower surface of the bridge 25 as shown in FIG. Note that the lower surface of the bridge 25 is curved in an arc shape according to the shape of the side surface of the capacitor body 31. Further, the width in the Y direction of the arm 261 and the pressing portion 262 is determined so that the presser 26 can pass between the pair of leads 32.

  Next, in a state where the side surface of the capacitor body 31 is in contact with the lower surface of the bridge 25, the capacitor 3 is moved toward the holding space 21 (X plus direction in FIGS. 5 and 6), and the upper surface 33 of the capacitor body 31 is moved. Is brought into contact with the front wall 23. When the capacitor 3 moves in the X plus direction, the presser 26 is pushed up in the Z plus direction. When the capacitor 3 is accommodated in the holding space 21, the capacitor main body 31 is held between the pressing portion 262 and the contact portion 22 by the elastic force of the arm 261. As a result, the resin case 2 holds the capacitor body 31 as shown in FIG. Thereafter, each of the pair of copper bars 41 is fixed to each of the pair of leads 32 by welding or soldering.

  According to the electronic device 1 described above, the following effects can be obtained.

  The electronic device 1 includes a resin case 2 that holds a capacitor main body 31. The resin case 2 contacts the side surface of the capacitor main body 31 and the side surface of the capacitor main body 31. A pressing portion 262 that presses against the contact portion 22. For this reason, the capacitor body 31 can be held between the contact portion 22 and the pressing portion 262 and the capacitor 3 can be held.

  In addition, the resin case 2 provided in the electronic device 1 includes a contact portion 22, a front wall 23, a pair of side walls 24, a bridge 25, and a presser 26 that are formed by integrally molding with a mold resin. For this reason, since the electronic device 1 can hold the capacitor body 31 only by the resin case 2 formed integrally, the manufacturing cost of the electronic device 1 can be reduced.

  In addition, an opening S1 is formed in the resin case 2 provided in the electronic device 1, and the bottom surface 35 of the capacitor body 31 in a state where the resin case 2 holds the capacitor body 31 by the opening S1. Is opened so as not to contact the resin case 2. For this reason, the explosion-proof valve formed on the bottom surface 35 of the capacitor body 31 is not blocked. Therefore, the electronic device 1 can hold the capacitor 3 without hindering the function of the explosion-proof valve of the capacitor 3.

  In addition, the resin case 2 provided in the electronic device 1 has a contact portion 22 that contacts the side surface of the capacitor body 31 and a pressing portion 262 that contacts the side surface of the capacitor body 31 in the same plane orthogonal to the holding axis. Touch. For this reason, the pressing part 262 and the contact part 22 are in contact with the capacitor body 31 at a position where the holding axis directions coincide. Therefore, the electronic device 1 can stably hold the capacitor 3 as compared with the case where the pressing portion 262 and the contact portion 22 are in contact with the capacitor main body 31 at different positions in the holding axis direction.

  Further, in the electronic device 1, the pressing portion 262 and the contact portion 22 come into contact with the capacitor body 31 at a position on the side surface of the capacitor body 31 that is closer to the bottom surface 35 than the center of the capacitor body 31 and in the holding axis direction. In addition, the contact portion 22 contacts the capacitor main body 31 from the position in the holding axis direction to the position where the front wall 23 is erected. For this reason, since the area where the side surface of the capacitor body 31 is in contact with the contact portion 22 can be secured, the electronic device 1 can hold the capacitor 3 more stably.

  The resin case 2 provided in the electronic device 1 has an opening S <b> 2 in a region sandwiched between the bridge 25 and the presser 26, the pair of copper bars 41, and the pair of side walls 24. Therefore, when the capacitor main body 31 is held in the resin case 2 as described above with reference to FIGS. 4 to 6, the capacitor 3 can be moved without the interference of the pair of leads 32. Further, since the width in the Y direction of the arm 261 and the pressing portion 262 is smaller than the distance between the pair of leads 32, the capacitor 3 can be moved without the pair of leads 32 interfering with the presser 26. Furthermore, since the bridge 25 abuts against the side surface of the capacitor body 31, the capacitor 3 can be held more stably and can be used as a guide for moving the capacitor 3 toward the holding space 21. Therefore, workability when holding the capacitor 3 in the electronic device 1 can be improved.

  The resin case 2 provided in the electronic device 1 has a guide 27 formed on the upper surface of the front wall 23. Therefore, when the capacitor 3 is moved from the state shown in FIG. 6 to the state shown in FIG. 2, the movement of the lead 32 enters the groove of the guide 27, and the movement of the lead 32 is guided to the copper bar 41. Will be. Therefore, the workability when holding the capacitor 3 in the electronic device 1 and the workability when fixing the lead 32 and the copper bar 41 by welding or soldering can be improved.

  Further, the electronic device 1 can stably hold the capacitor 3 as described above. According to this, it is possible to prevent the position of the capacitor 3 from being shifted after the electronic device 1 holds the capacitor 3 and before the copper bar 41 is fixed to the lead 32 by welding or soldering. Therefore, the workability at the time of fixing by welding or soldering can be improved. Further, even after the copper bar 41 is fixed to the lead 32 by welding or soldering, the capacitor 3 can be stably held by the resin case 2, so that stress due to vibration is applied to the lead 32. The breakage of the lead 32 can be suppressed.

  In addition, the electronic device 1 is provided with a pressing portion 262 at a position orthogonal to the direction in which the plurality of capacitors 3 are arranged (Y direction in FIG. 1). For this reason, the space | interval of the mutually adjacent capacitors 3 can be narrowed, and the electronic device 1 can be reduced in size.

  Here, as described above, the third opening S5 is formed so that the lead 32 can pass when the capacitor body 31 moves linearly. For this reason, when the capacitor main body 31 is linearly moved, the pair of leads 32 can be protruded to the outside of the holding space 51 through the third opening S5. Therefore, the capacitor body 31 can be linearly moved without the pair of leads 32 interfering with the first contact portion 52 and the front wall 53.

Therefore, compared with the case where the pressing portion 57 and the first contact portion 52 are in contact with the capacitor main body 31 at different positions in the holding axis direction, the electronic device 1A can hold the capacitor 3 stably. .

  Further, in the electronic device 1 </ b> A, the first contact portion 52 and the pressing portion 57 at the same position in the holding axis direction among the side surfaces of the capacitor body 31 on the upper surface 33 side from the center of the capacitor body 31 are the capacitor body 31. In addition, the second contact portion 55 contacts the capacitor body 31 on the bottom surface 35 side from the center of the capacitor body 31 and on the side opposite to the side where the first contact portion 52 contacts. That is, the first contact portion 52 and the second contact portion 55 are in contact with the side surface of the capacitor body 31 with the side surface of the capacitor body 31 interposed therebetween. For this reason, the first contact portion 52 and the pressing portion 57 and the second contact portion 55 can be brought into contact with the capacitor body 31 at positions separated from each other in the central axis direction of the capacitor body 31. The electronic apparatus 1A can hold the capacitor 3 more stably.

  The resin case 5 provided in the electronic apparatus 1A has a first opening S3. For this reason, the capacitor 3 can be inserted from the bottom surface 35 of the capacitor body 31 toward the holding space 51 from the first opening S3.

  A second opening S4 is formed in the resin case 5 provided in the electronic apparatus 1A. For this reason, the capacitor body 31 can be inserted into the holding space 51 without the bottom surface 35 side of the capacitor body 31 interfering.

  The resin case 5 provided in the electronic apparatus 1A has a third opening S5. Specifically, the third opening S5 is provided across the front wall 53 and the position of the first contact portion 52 facing the copper bar 71. Therefore, when the capacitor body 31 is held in the resin case 5, the capacitor body 31 is inserted into the holding space 51 without causing the pair of leads 32 to interfere with the first contact portion 52 and the front wall 53, and rotated. After moving, it can be moved linearly. Therefore, workability when holding the capacitor 3 in the electronic apparatus 1A can be improved.

  Further, when the capacitor 3 is moved from the state shown in FIG. 12 to the state shown in FIG. 8, the movement of the lead 32 enters the third opening S5 and the movement of the lead 32 is restricted to the copper bar 71. You will be guided. Therefore, the workability when holding the capacitor 3 in the electronic device 1A and the workability when fixing the lead 32 and the copper bar 71 by welding or soldering can be improved.

  Further, the electronic device 1A can stably hold the capacitor 3 as described above. According to this, it is possible to prevent the position of the capacitor 3 from being shifted after the electronic device 1A holds the capacitor 3 and before the copper bar 71 is fixed to the lead 32 by welding or soldering. Therefore, the workability at the time of fixing by welding or soldering can be improved. Further, even after the copper bar 71 is fixed to the lead 32 by welding or soldering, the capacitor 3 can be stably held by the resin case 5, so that stress due to vibration is applied to the lead 32. The breakage of the lead 32 can be suppressed.

  In addition, the electronic device 1A is provided with a pressing portion 57 at a position orthogonal to the direction in which the plurality of capacitors 3 are arranged (Y direction in FIG. 7). For this reason, the space | interval of the mutually adjacent capacitors 3 can be narrowed, and 1 A of electronic devices can be reduced in size.

  Further, in each of the above-described embodiments, the lead 32 is bent in an L shape. However, the present invention is not limited to this, and the lead 32 may be linear without being bent. In this case, the surface of the copper bar 71 fixed to the lead 32 may be parallel to the direction of the lead 32.

  Further, in the second embodiment described above, the pressing portion 57 is in contact with the upper surface 33 side of the capacitor body 31 from the center of the capacitor body 31. Here, a groove may be formed on the side surface of the capacitor body 31, for example, in the vicinity of the upper surface 33. Therefore, when a groove is formed, the pressing portion 57 may be provided at a position where the resin case 5 is caught in the groove in the state where the capacitor case 31 is held. According to this, the capacitor 3 can be held more stably.

  In each of the above-described embodiments, the electronic device 1 and the electronic device 1A may be used for fixing the capacitor 3 to the substrate, and hold the capacitor 3 alone, the capacitor 3, and other components. It may be used for this purpose.

  In the first embodiment described above, the pressing portion 262 is provided so as to protrude from the distal end portion of the arm 261 extending from the bridge 25 toward the contact portion 22. However, the present invention is not limited to this, and may be provided so as to protrude from the bridge 25 toward the contact portion 22 as in the pressing portion 262A of FIG. For example, as shown in FIG. 14, the arm 261 extends from the side of the resin case 2 to which the copper bar 41 is attached, and a pressing portion 262 projects from the distal end portion of the arm 261 toward the contact portion 22. It may be a thing.

  Moreover, you may provide the slit S6 in the 2nd contact part 55 in the above-mentioned 2nd Embodiment, as shown in FIG. According to this, compared with the case where slit S6 is not provided, the 2nd contact part 55 becomes easy to elastically deform. Therefore, workability can be improved when the capacitor body 31 is held in the resin case 5 as described above with reference to FIGS.
