Description

  The present invention relates to an electronic device having a connection terminal for inputting / outputting signals between a plurality of electronic devices, in particular, a connection terminal capable of supporting a connection plug when the connection plug connected to the connection terminal is inserted. The present invention relates to an electronic device having a reinforcing structure.

  Conventionally used electronic devices generally have a connection terminal for connection to other electronic devices, and a connection plug is connected to this connection terminal to input / output signals between a plurality of electronic devices. I am doing so. Such a connection terminal is mounted by being electrically connected to a circuit board fixed in a housing. Conventionally, various structures have been proposed as a structure for fixing the connection terminal to the circuit board. . For example, in the mounting structure of the jack shown in Patent Document 1, the jack is fixed to the circuit board by inserting the leg portion formed on the jack into the notch formed on the circuit board, and a box-type press holder that covers the jack is provided. The hook formed on the press holder is engaged with a through hole formed on the circuit board so that the jack is supported by the press holder. Further, the connector shown in Patent Document 2 forms a board insertion portion by forming a lateral slit at the base of the pin jack body, and a spring-type contact built in the board insertion portion is formed on the circuit board. The pin jack is fixed to the circuit board by elastically holding the connection part by the contact, and the circuit board and the pin jack are electrically connected by contacting the contact with the wiring round of the connection part. Configured to connect.
