  • the capacitor holder described in Patent Document 1 has a structure in which the capacitor is held from the side between both ends in the longitudinal direction of the capacitor. Will be placed sideways.
  • the present invention has been made to solve the above-described problem, and its object is to provide a capacitor capable of reducing the interval to be secured between adjacent capacitors when mounting a plurality of capacitors in parallel to that of a conventional product. It is to provide a holding tool.
  • the capacitor holder according to the first aspect of the present invention is formed of an electrically insulating material, and has a main body portion that can be fitted with a tip of the capacitor, a metal material, and is fixed to the main body portion.

  • various capacitors are assumed as the capacitors.
  • Various capacitors include electrolytic capacitors.
  • a general form of this electrolytic capacitor includes a cylindrical case, a lead extends from one end of the case, and a pressure valve that expands or ruptures when the internal pressure becomes excessive at the other end of the case. It has a form.
  • the longitudinal direction of the capacitor means the axial direction of the cylindrical case described above
  • the radial direction of the capacitor means the radial direction of the cylindrical case described above.
  • the tip of the capacitor means the other end of the case described above (that is, the end where no lead is provided).
  • the capacitor holder of the present invention since the capacitor fitted in the main body can be held at the mounting location, even when vibration or impact is transmitted to the capacitor, an excessive load is applied to the capacitor due to the vibration or impact. This can be prevented.
  • the lead portion is fixed to the main body portion at a position opposite to the capacitor across the reference surface. For this reason, even if the structure on the end face side of the capacitor becomes bulky due to the provision of the lead portion, the structure on the side of the capacitor does not become bulky.
  • such a capacitor holder has a dimension that matches the longitudinal direction of the capacitor as compared to a capacitor in which a lead portion is disposed on the side of the capacitor (for example, the one described in Patent Document 1). Even if it increases, the dimension that matches the radial direction of the capacitor can be reduced. Therefore, when the capacitor holder of the present invention is used when mounting a plurality of capacitors in parallel, the interval to be secured between adjacent capacitors can be reduced more than the conventional product.
  • the capacitor holder when the lead portion is located on the opposite side of the capacitor across the reference surface, if the force is applied to the capacitor in a direction to separate the capacitor from the printed wiring board, the force is When acting on the capacitor holder, the capacitor holder tends to be displaced in the direction of tilting with the lead portion as the rotation center. Therefore, the capacitor holder is less likely to be pulled out from the printed wiring board than when the force acting from the capacitor is the force that pulls the lead portion straight out.
  • the opening of the main body exposes the pressure valve provided at the tip of the capacitor. Therefore, it is possible to attach the capacitor holder without hindering the function of the pressure valve.

  • the capacitor holder of the present invention unlike the case of being fixed to the printed wiring board with an electrically insulating member different from the metal lead portion, not only holding the capacitor but also the capacitor It can also take measures against high frequency noise.
  • capacitors are electronic components with relatively large tolerances, and there are some individual differences in longitudinal dimensions and diameters. Therefore, if the lead part is provided on the side of the capacitor, individual differences may occur in the distance between the capacitor side surface and the lead part due to the radial tolerance of the capacitor itself. Such high frequency noise countermeasure effects may vary.
  • the distance between the tip surface of the capacitor and the lead portion is as follows. Regardless of the tolerance in the longitudinal direction of the capacitor itself, the distance is as set on the capacitor holder side.
  • the capacitor holder of the present invention can stably exhibit the above-described high-frequency noise countermeasure effect regardless of the tolerance in the longitudinal direction of the capacitor itself.
  • the lead portion When holding a capacitor having a tolerance in the radial direction, if the lead portion is provided on the side of the capacitor, the lead portion may be a factor that hinders the main body portion from expanding and deforming in the radial direction. In this case, if the distance between the lead portions is narrow, the capacitor having a large diameter within the tolerance range may be held at an excessively high holding pressure by the capacitor holder. On the other hand, if the distance between the lead portions is increased, the capacitor having a small diameter within the tolerance range may not be properly held due to insufficient holding pressure by the capacitor holder.
  • the lead portion is provided on the end face side of the capacitor, the lead portion is unlikely to be a factor that hinders the main body portion from expanding and deforming in the radial direction. Therefore, the holding pressure of the capacitor is not excessively increased or decreased due to at least the lead portion, and optimization of the holding pressure is facilitated.
  • the capacitor holder of the second aspect of the present invention is the capacitor holder of the first aspect, wherein the lead portion is viewed from the fitting direction when the tip of the capacitor is fitted into the main body portion. In the position which overlaps with the front end surface of the capacitor, it is fixed to the main body.
  • the lead portion is positioned so as to overlap the tip surface of the capacitor, when the force for displacing the capacitor in the longitudinal direction is applied to the capacitor, the lead portion Can be received in the existing part.
  • the force acting on the capacitor holder from the capacitor is more firmly received on the capacitor holder side than when the lead is not in a position where it overlaps the front end surface of the capacitor, thereby preventing displacement of the capacitor more reliably. Can do.

If the lead portion is at a position where it overlaps the tip end surface of the capacitor, the main body portion of the capacitor holder can be reinforced by the lead portion, and the main body portion of the capacitor holder can be prevented from being damaged due to the burst of the capacitor.
