  By the way, a substrate on which an electronic component is mounted is usually made of a resin such as glass epoxy and has low rigidity, so that it easily vibrates when receiving vibration input from the outside. For this reason, especially when a component that is relatively heavy as an electronic component such as a coil or a capacitor is attached to the substrate, the vibration of the substrate becomes noticeable due to the vibration input, and the mounting state of the component is deteriorated. .

  Accordingly, an object of the present invention is to increase the mounting strength of components to a substrate.

  In the present invention, when a component is attached to a substrate by a fastening portion and a plurality of joint portions, the plurality of joint portions are set at positions separated from each other on the substrate, and the plurality of joint portions are fastened at the fastening portion. In a state where the component is fastened to the substrate by the means, an adhesive is interposed in the gap between the substrate and the bonding portion and the substrate are bonded.

  According to the present invention, the structure is such that the component is attached to the substrate by the fastening portion and the joint portion, and in the joint portion, the thickness of the adhesive can be appropriately managed by the gap between the component and the substrate. The bonding strength is increased, and the mounting strength of the component to the substrate can be increased. In addition, since the plurality of joints are set at positions separated from each other on the board, even if one part is peeled off, the joined state at the other part can be maintained, and the attachment strength of the component to the board can be reduced. It can be suppressed as much as possible.

Grid-shaped reinforcing ribs 121 are integrally formed on the side wall 113.

  Components such as coil cases 125 and 127 serving as part product holders for winding and holding the coil 123 are attached to one surface of the substrate 117 opposite to the side wall 113. For this reason, the reinforcing rib 121 is provided on the substrate mounting surface 113 a facing the other surface of the substrate 117.

  The bolt hole 129 of the substrate 117 and the bolt mounting portion 119 of the side wall 113 of the filter box 112 are made to correspond to each other, and a bolt (not shown) is inserted into the bolt hole 129 and fastened to the bolt mounting portion 119. It is attached to the board attachment surface 113a of the side wall 113.

  18 to 20 show the coil case 125 made of resin. The coil case 125 includes a support part 131 located on the lower side and a coil holding part 133 located on the upper side of the support part 131. The coil holding part 133 has a through hole 133a at the center and is formed in a substantially disk shape when viewed from the front. The coil 123 is wound around the coil holding part 133 through the through hole 133a.

  Further, the outer shape of the bottom surface of the support portion 131 has a substantially rectangular shape that is long in the left-right direction in FIG. 20, and bolt fastening portions 137 as fastening portions are formed at the four corners of the bottom surface.

Is located. For this reason, when the bolt fastening portion 137 is fastened on the substrate 117, a gap of height H is formed between the substrate 117 and the bottom surface 139a of the joint portion 139.

  Then, by applying an adhesive as a bonding means to the bottom surface 139a of the bonding portion 139, the bonding portion 139 and the surface of the substrate 117 are bonded via the adhesive. At this time, since the adhesive is located in the gap corresponding to the height H, the adhesive can be reliably interposed between the substrate 117 and the bottom surface 139a of the joint portion 139. In addition, since the bottom surface 139a of the joint portion 139 is circular, the adhesive can be efficiently applied to the entire bottom surface 139a.

  On the other hand, as shown in the front view of FIG. 21, the reinforcing rib 121 provided on the side wall 113 of the filter box 112 intersects the vertical rib 143 extending in the vertical direction (vertical direction) and the vertical rib 143. The horizontal ribs 145 extending in a substantially horizontal direction (lateral direction) form a lattice shape.

  Of these reinforcing ribs 121, a vertical rib 143 corresponding to a central axis M extending in the vertical direction is located at the center in the left-right direction of the support portion 131 of the coil case 125 whose attachment to the filter box 112 is indicated by a two-dot chain line. The first reinforcing rib 147 is used. Further, the lateral rib 145 corresponding to the central axis N passing through the center in the vertical direction of the support portion 131 of the coil case 125 and extending in the lateral direction is defined as a second reinforcing rib 149.

  The first reinforcing rib 147 constitutes a first reinforcing portion, and the second reinforcing rib 149 constitutes a second reinforcing portion, and the first reinforcing portion and the second reinforcing portion constitute a reinforcing portion.

  Then, when the coil case 125 is attached to the side wall 113, three joint portions 139 provided on the support portion 131 of the coil case 125 are arranged on the first reinforcing rib 147 and also on the second reinforcing rib 149. Be placed. The four bolt fastening portions 137 are disposed on the vertical rib 143. In addition, as shown in FIG. 21, the coil case 127 arranged on the lower side of the same shape as the coil case 125 similarly has the five joint portions 151 arranged on the first reinforcing rib 147 and the second reinforcing rib 149. Is done. The four bolt fastening portions 153 are disposed on the vertical rib 143.

  Here, the height of the first reinforcing rib 147 and the second reinforcing rib 149 from the board mounting surface 113a is substantially the same as the height of the bolt mounting part 119 from the board mounting surface 113a. It is higher than the height from the board mounting surface 113a.

  That is, when the substrate 117 is attached to the substrate attachment surface 113a, the back surface of the substrate 117 is in contact with the distal end surface of the bolt attachment portion 119, and the distal end surfaces of the first reinforcement rib 147 and the second reinforcement rib 149 that are the reinforcement portions. Also abut. At this time, the heads of the bolts 138 used when the coil cases 125 and 127 are attached to the substrate 117 are the other reinforcing ribs 121 and the substrate that are lower than the first reinforcing rib 147 and the second reinforcing rib 149. 117.

  As described above, according to the present embodiment, the first reinforcing rib 147 and the second reinforcing rib 149 provided on the substrate mounting surface 113a of the filter box 112 are the components of the coil 123 and the coil case 125 (127). It is set at a position corresponding to the central axes M and N.

  Here, the coil 123 and the coil case 125 (127) are attached in a state indicated by a two-dot chain line in FIG. It is.
