を特徴とする。(G. Effect of the Invention) As is apparent from the above description, the external connector holding structure of the electronic device of the present invention comprises the outer casing of the electronic device,
A printed circuit board disposed in the outer casing, an external connector disposed on the printed circuit board and having a tip end exposed from an insertion hole formed in the outer casing, and detachable from the outer casing. And a holding portion which is a part of the outer casing and is divided at an insertion hole portion for exposing the distal end portion of the external connector, and which holds the external connector in the front-rear direction when attached to the outer casing. And an external connector holding member.

故の発生を防止することができる。Therefore, according to the external connector holding structure of the electronic device of the present invention, the force applied to the mounting portion between the external connector and the printed circuit board can be received by the connector holding member when the plug is attached to or detached from the external connector, and the external connector and the printed board can be printed. It is possible to reduce the load on the mounting portion to the board and prevent the occurrence of backlash of the mounting portion, detachment of the external connector, damage, and peeling of the circuit pattern.

る。Further, in the external connector holding structure of the electronic device of the present invention, since the external connector holding member is detachable from the outer casing, the two side edges of the printed circuit board which are orthogonal to each other are adopted, as adopted in the above embodiment. Parts protruding from the outer casing to the outside (the knob 22a of the variable resistor 22 and the external connector 23
It can be applied to an electronic device provided with the jack portion 23a). That is, when the parts protruding from the outer casing to the outside are arranged on two side edges of the printed circuit board which are orthogonal to each other,
When this printed circuit board is housed in the outer casing, if the component arranged on one side edge is inserted into the insertion hole of the outer casing, the component arranged on the other side edge is inserted into the insertion hole of the outer casing. However, like the external connector holding structure of the electronic device of the present invention, the external connector holding member can be attached to and detached from the outer casing so that one of the parts can be first projected to the outside from the insertion hole of the outer casing. This can be realized by attaching the printed circuit board inside the outer casing and then attaching the external connector holding member to the outer casing.
