It is comprised so that a contact force may increase. Although not shown, the relationship between the left terminal 70A and the lead portion 16A is the same as described above.

(Function and effect)
Next, the operation and effect of this embodiment will be described.
In the capacitor holder 10 described above, the first holder 20 to which the capacitor main body 14 is attached holds the capacitor main body 14 alone. The second holder 50 holding the terminals 70A and 70B having the contact portions 72A and 74A is attached to the first holder 20 holding the capacitor main body 14. Thereby, the contact portions 72A and 74A of the terminals 70A and 70B come into contact with the lead portions 16A and 16B of the capacitor 12. Since it is configured in this way, when the capacitor main body 14 is mounted on the first holder 20, it is possible to prevent the lead portions 16A and 16B from inadvertently contacting and deforming or damaging the terminals 70A and 70B. As a result, the capacitor main body 14 can be mounted on the first holder 20 without considering the deformation and damage of the lead portions 16A and 16B, and the capacitor 12 can be easily mounted on the capacitor holder 10.

  Further, in the present embodiment, the contact portions 72A and 74A of the terminals 70A and 70B are in sliding contact with the lead portions 16A and 16B during the time from the middle of mounting the second holder 50 to the first holder 20 until the mounting is completed. As a result, even when an oxide film is formed on the surface of any of the contact portions 72A and 74A and the lead portions 16A and 16B, the oxide film can be scraped off by the above-described sliding contact, so that the terminals 70A and 70B The lead portions 16A and 16B can be electrically connected to each other. Further, even if foreign matter adheres to the surface of any of the contact portions 72A and 74A and the lead portions 16A and 16B, the foreign matter can be removed by the sliding contact, so that the terminals 70A and 70B and the lead portion 16A and 16B can be made to conduct well.

  Further, in the present embodiment, the contact force between the contact portions 72A and 74A of the terminals 70A and 70B and the lead portions 16A and 16B increases in a state where the second holder 50 is attached to the first holder 20 in a state where the attachment is completed. As a result, the contact force between the contact portions 72A, 74A and the lead portions 16A, 16B can be reduced while ensuring a good conduction state between the terminals 70A, 70B and the lead portions 16A, 16B in the mounted state. Can be set. As a result, deformation and damage of the lead portions 16A and 16B due to the high contact force at the beginning of the contact can be prevented. Moreover, since the force required for mounting the second holder 50 to the first holder 20 can be set low, the mounting of the second holder 50 to the first holder 20 is facilitated.

  Further, in the present embodiment, the terminals 70A and 70B held by the second holder 50 have a pair of sandwiching pieces 72 and 74 facing each other, and are provided on the opposing surfaces of the pair of sandwiching pieces 72 and 74, respectively. Contact portions 72A and 74A are provided. The lead portions 16A and 16B are inserted between the contact portions 72A and 74A in the middle of the mounting. Further, during the period from the middle of the mounting to the completion of the mounting, the guided portions 72C and 74C of the sandwiching pieces 72 and 74 are in sliding contact with the inclined surfaces 32A and 34A provided on the first holder 20. By this sliding contact, the clamping pieces 72 and 74 approach each other. As a result, the contact force between the contact portions 72A and 74A of the sandwiching pieces 72 and 74 and the lead portions 16A and 16B is increased in the mounting completion state than during the mounting. Thus, since the sandwiching pieces 72 and 74 are configured to be in sliding contact with the inclined surfaces 32A and 34A (guide portions) provided on the first holder 20, the inclination angles of the inclined surfaces 32A and 34A and the like (of the guide portions) The degree of increase in the contact force can be easily adjusted by setting the shape and the like.
