。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a contact pin, and in particular to an elliptical mounting portion of a contact pin for mechanically fixing it to a through-hole portion of a printed circuit board and for electrically connecting it. Concerning dispatch. [Prior Art] Conventionally, in this type of contact bottle, the structure of the mounting portion that contacts the through-hole portion of the printed circuit board is such that the cross-sectional shape of the mounting portion is rectangular and diagonal. The solid bottle type 11 is finished with high precision dimensions and the inner diameter of the through hole part 8 is also finished with high precision for press-fit connection, and the other is the solid bottle type I1 with suitable unevenness in the cross-sectional shape and diagonal dimensions as shown in Fig. 4. It was constructed in two types: a compliant bin type 12 with flexibility.

有していた。In the two types of conventional contact pins mentioned above, the first solid pin pin is used to stabilize the mechanical holding force when the mounting part is press-fitted into the through-hole part of the printed circuit board. Furthermore, in order to maintain a stable electrical connection, it is necessary to finish the diagonal dimensions of the mounting part and the inner diameter of the through-hole part of the printed circuit board with high precision, which not only increases the cost but also causes slight variations in dimensional conditions. This had the disadvantage that it greatly affected the electrical and mechanical properties mentioned above. In addition, in the second compliant bottle type, the dimensional conditions of the inner diameter of the bottle and through-hole part can be relaxed because elasticity is given to the mounting part in the diagonal dimension direction during press-fitting, but it is difficult to form a concave part by press working. However, the cross-sectional area reduction rate is large, the mechanical strength is weak, and the bottle may bend or break during or after the press-fit connection.
本発明の目的は、上記従来の欠点を除くべく、柔軟性を

次に、本発明について図面を参照して説明する。The contact pin of the present invention has a concave arm portion having a V-shaped or U-shaped cross section or a similar shape from one side of an intermediate mounting portion that is press-fitted into a through-hole portion of a printed circuit board at a symmetrical position. At least two strips are provided, and the corners of the terminals on both sides of the groove and the corners of the terminal on the opposite side to the side on which the groove is provided are inscribed in the through-hole portion, and the diagonal corners of each terminal are inscribed in the through-hole portion. A chamfered part is provided on the part. [Example] Next, the present invention will be described with reference to the drawings.

の状態が示されている。Figure 1(a). (b). Referring to (c), the contact bin according to the present embodiment has an intermediate mounting part 1 so as to be able to be fitted and fixed into a through-hole part 8 of a printed circuit board, and is located at a symmetrical position from one side of this mounting part 1. Article 2 V
Concave arm portions 2 and 3 are provided. The terminal corners 4 and 5 formed at both ends of these concave grooves 2 and 3 are shaped more open than the terminal corners 6 and 7 formed on the opposite side, and are press-fitted into the through-hole section 8. In this case, each terminal corner 4
, 5, 6.7 are press-fitted into the conductive through-hole portion 8 of the printed circuit board with sufficient contact pressure, and the compliant pin portion 9 is capable of elastically changing the cross-sectional shape of the mounting portion 1. ．． In the compliant pin portion 9 of this embodiment configured as described above, before insertion into the through-hole portion 8 of the printed circuit board, the diagonal dimensions of the terminal corner portions 4-7 and 5-6 are the same as that of the through-hole portion 8. It has a dimension larger than the inner diameter, and when inserted into the through-hole portion 8, the terminal corner portions 4 and 5 are elastically deformed to settle into the positional relationship shown in Fig. 1(c), preventing damage to the through-hole portion 8. It can be inserted with a relatively light load without triggering. FIG. 2 shows the state in which the contact pin of this embodiment is inserted into the through-hole portion 8 of the printed circuit board 10.

得られる．In this embodiment, the concave groove is illustrated as having two grooves, but it may have two or more grooves, and its shape is not limited to a V-shape, but may be a U-shape or a similar shape. ．． [Effects of the Invention] As explained above, the present invention is achieved by symmetrically arranging a concave portion having a V-shaped or U-shaped cross section or a shape similar thereto from one side of the contact bin intermediate mounting portion. This has the effect of realizing a contact pin that has the advantages of both a compliant pin and a solid pin. That is,
It is possible to give the characteristics of a compliant bin by elastically deforming the corner of the terminal on the groove side, and the press-fitting characteristics of a solid bin can be obtained by press-fitting each part of the terminal on the opposite side to the edge. As a result, the tolerance between the diagonal dimension and the inner diameter dimension of the through-hole part can be relaxed, and the cross-sectional area reduction rate can be kept to a minimum, resulting in high mechanical strength against bending and breaking during press-fitting. As a result, a contact bottle of high quality and excellent usability can be obtained, which is completely unaffected by rotational torque during wire wrapping connection after pressing, for example.
