度を低下させるような欠点があった。Conventional methods for attaching board-mounted connectors to boards have been either soldering or press-fitting, so in the former method, the connector is temporarily fixed so that it does not move when soldering, and the soldering is done after cleaning with flux and soldering. This required a lot of man-hours for corrections, and added heat stress, which degraded the reliability of the board. The latter does not require soldering, but has the disadvantage that a large amount of force is required when press-fitting, and the connector is press-fitted into the inner wall surface of the connector mounting hole on the board, causing scratches, which also reduces the reliability of the board. was there.
本発明の目的は、信頼性を損なわずに、簡単な方法で基

ている。Shape memory effect is a phenomenon in which a metal material in a martensitic state at a low temperature returns to its original shape before deformation when heated.
i-Ni alloy and C1L-Zn-At alloy have been put into practical use.
以下、本発明の実施例を図面を用いて詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

他は省略しである。FIG. 1 is a partial view of a pin contact of a board-mounted connector according to an embodiment of the present invention, which is made of a shape memory alloy and has a shape memorized as shown in FIG. Only the board mounting part 1 and contact part 2 are shown.
Others are omitted.
第２図は、第１図のピンコンタクトを低温で基板取付部
１を塑性変形させたものである。FIG. 2 shows the pin contact shown in FIG. 1 with the board mounting portion 1 plastically deformed at a low temperature.

内径８を表わしている。FIG. 5 is a cross-sectional view of the substrate to which the connector is attached. The base material 5 has a conductive portion 6 and a connector mounting hole 7, and the finished inner diameter 8 of the mounting hole 7 is shown.
今基板取付部１．対角線６を取付穴、内径８より大きく
、対角線４を内径８より小さく設定しておく。Now board mounting part 1. The diagonal line 6 is set to be larger than the inner diameter 8 of the mounting hole, and the diagonal line 4 is set smaller than the inner diameter 8.

けである。FIGS. 6 and 7 show another embodiment f13 of the present invention, and are sectional views of the board mounting portion 1. FIG. A state 10 is shown in which the state 9 in which the shape is memorized is changed to a plastic shape at a low temperature. That is, the only thing different from FIG. 1 and FIG. 2 is the shape of the board mounting portion.
