Description

  The present invention mainly relates to an electronic component connecting terminal used when an electronic component such as a vibration actuator is attached to a location other than a substrate such as an electronic device casing, and an electronic component mounting structure using the same.

  Conventionally, the mounting structure of electronic parts such as vibration actuators is mounted by placing electronic parts such as vibration actuators on a mounting board housed in electronic equipment and soldering the terminals to the pattern on the mounting board. A structure (surface mounting) in which an electronic component is directly attached to a substrate is widely known.

  On the other hand, the electronic component mounting structure uses a clip-type terminal formed by pressing a conductive metal plate material such as a fuse clip, and this clip-type terminal is fixed at a desired position of the electronic device. In addition, it is also known that an electronic component is attached to a mounting board or other location without depending on solder by holding a connection terminal of the electronic component in a clip portion formed of a pair of spring-like holding pieces (for example, , See Patent Document 1).
