本発明は電気接触ピンに関し、特にプリント回路板のス
ルーホール部に機械的に固定し電気接続する中間取付部
を有する電気接触ピンに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electrical contact pin, and more particularly to an electrical contact pin having an intermediate mounting portion for mechanically securing and electrically connecting to a through-hole portion of a printed circuit board.

ている。中間取付部３のコーナー部５とは異なる方の対
角上には面取り６がされている。Conventionally, as shown in FIGS. 4A and 4B, this electrical contact pin has a tip 1, an insertion taper s2, and an intermediate mounting portion 3 that is fitted and fixed into a through-hole portion of a printed circuit board.
Triangular grooves 4 are provided on the two opposite corners adjacent to the diagonal corner portions 5 of the intermediate mounting portion 30, extending to a position past the insertion taper portion 2. These grooves 4 are alternately arranged facing each other. A chamfer 6 is formed on the diagonal corner of the intermediate attachment part 3 that is different from the corner part 5.

なスルーホール部内径の範囲に限界が生じ、結局細径用
と太径用の２種類の電気接触ピンを準備しなけれはなら
ないという欠点があった。In such a conventional electrical contact pin, as shown in FIG. 4C, the corner portion 5 of the intermediate mounting portion 3 has elasticity in the diagonal direction due to the function of the groove portion 4, so that the inner diameter of the through-hole portion 23 into which it is inserted is It has become possible to deal with differences to some extent. However, the inner diameter of the through-hole portion of printed circuit boards for high-density mounting, such as those used in computers, is usually 0.8 mm.
However, other electronic devices still require through-holes with large inner diameters, such as 1.1 mm in diameter, so through-holes over a wider range are required. There is a need for an electrical contact pin that can accommodate different hole inner diameters. However, in the conventional electrical contact pin as described above, there is a limit to the range of the inner diameter of the through-hole part that can absorb the contact force with the through-hole part and the diagonal displacement of the corner part 5 of the intermediate mounting part 3. This resulted in the disadvantage that two types of electrical contact pins, one for small diameter and one for large diameter, had to be prepared.
また、溝部４はスルーホール部２３と最初に接触する挿

いるので、挿入テーパー部２と溝部４との間の肉厚が薄
くなり、外部から力が働くと折れやすいという欠点があ
った。In addition, the groove portion 4 is extended at a position past the insertion taper portion 2 at 1 so that the insertion taper portion 2 that first contacts the through-hole portion 23 also has elasticity in its diagonal direction. The wall thickness between the insertion taper part 2 and the groove part 4 is thin, and there is a drawback that it is easy to break when external force is applied.
また、このように構成される電気接触ピンの溝部４は通
常１回のみのプレスにより形成されるが、その方法だと

入力や接触性、保持力がバラつくという欠点があった。Further, the groove portion 4 of the electrical contact pin constructed in this way is usually formed by pressing only once, but since the dimensional accuracy is not good with that method, it is difficult to obtain the necessary dimensions.
There was a drawback that the insertion force into the through hole, contact performance, and retention force varied depending on the completed electrical contact pin.

ない。Referring to FIGS. 1A and 1B, which show an embodiment of the present invention, the electrical contact pin 31 of the present invention has a tip 7 that is connected to a through-hole portion of a printed circuit board, and a tip portion 7 that contacts the through-hole portion. and an insertion tapered portion 8 having an inclined surface whose diameter increases from the distal end portion 7 toward the intermediate attachment portion 9. Diagonal corner part 1 from the intermediate mounting part 9 to the middle of the insertion taper part 8
On two opposing surfaces adjacent to 2, alternately opposing grooves 1
0 is provided, and a part of the center of the groove 10 is an expanded groove 11 having an opening wider than the groove 10. Moreover, a chamfer 13 is provided on a diagonal corner portion of the intermediate attachment portion 9 that is different from the corner portion 12 . The expansion groove 11 provided in a part of the groove 10 expands the range of diagonal displacement of the intermediate attachment part 9, so that a wider range of through-hole inner diameters can be accommodated. Furthermore, since the groove portion 10 is provided only up to the middle of the insertion taper portion 8, if the position where the insertion taper portion 8 first contacts the through-hole portion is a position where the groove portion 10 is not provided, the insertion taper portion 8 does not have sufficient elasticity and may damage the through-hole section. In order to prevent this, the facing portion 14 is provided in the matcher taper portion 8 so that the position where it first comes into contact with the through hole portion is at a position where it has flexibility due to the action of the groove portion 10. However, this imposition part 14 is
If the portion of the insertion tapered portion 8 that first comes into contact with the through-hole portion has sufficient elasticity, it is not necessary to provide it.

A groove 10 is formed by pressing the two opposing surfaces of the electrical contact pin with a coin punch 15 as shown in the figure, and then a part of the groove 10 is completely spanned with an expansion punch 16 as shown in FIG. 2B. One possible method is to perform expansion processing. Forming the expanded groove portion 11 by pressing twice in this manner has the advantage that the necessary diagonal dimensions can be obtained with high precision.

If provided, no damage will be caused to the through-hole portion of any inner diameter during insertion.
