プラグである。In the figure, 1 is an input / output terminal which is an electronic component to be connected to an external device, 1a and 1b are mounting portions formed integrally with the input / output terminal 1, 1c is an electrode terminal of the input / output terminal, 2 is a main body chassis portion, 2a is a board mounting portion from the main body chassis portion 2 provided for fixing the printed wiring board 3, 4 is a mounting screw, 5 is an adhesive, and 6 is a plug for electrical connection with an external device. .

り、接着剤５により固定する手法が用いられていた。Conventionally, in this type of electronic component, the electrode terminal 1c of the input / output terminal 1 is fixed by simply soldering to the substrate 3, so that the plug 6 is mounted and careless static pressure is applied to the tip of the plug 6. Then, there was a danger of breaking the soldered portion of the electrode terminal 1c. For this reason, as shown in FIGS. 6 and 7, a method has been used in which the input / output terminal 1 is provided with a board mounting portion 2a for connecting to the main body chassis portion 2 or is fixed with an adhesive 5.

出力端子の近傍に配置する必要から機構設計上の制約が
大きくなり、機器の小型化が困難となる。In addition, a board mounting portion 2a for fixing the board is drawn out from the main body chassis portion 2 in the vicinity of the input / output terminal 1 from the viewpoint of measures against radio interference, noise, and the like, and an electrode terminal serving as a ground portion of the input / output terminal. It was necessary to route the ground pattern on the board 3 between the board 1c and the board mounting portion 2a. [Problems to be Solved by the Invention] However, in the above-described conventional example, it is necessary to dispose the board mounting member in the vicinity of the input / output terminal, so that the restriction on the mechanism design is increased, and it is difficult to reduce the size of the device. Becomes

ズ対策ができないため、機器の品質上の問題となる。Further, an electrode terminal which is a grounding part in the input / output terminal,
Considering design variations between the board mounting part,
A certain distance is required, and at the same time, it is necessary to route the space with a conductor pattern on the substrate, which is a restriction on the pattern design. Further, since the thickness of the copper foil portion of the ground pattern is small, the ground impedance becomes high, and sufficient noise countermeasures cannot be taken. This poses a problem in the quality of equipment.
さらに、入出力端子の固定手段として第６図のよう
