る。 In conventional electrical contact pins of this type, the structure of the mounting part that contacts the through-hole part of the printed circuit board is made by cutting and bending a metal plate made of a conductive spring material (Fig. 1a, fig. b),
A hollow hole is provided in the mounting part to make the beam part flexible (second
(see Figure a and Figure 2 b). However, in order to promote high-density mounting of electronic components on printed circuit boards, it is necessary to reduce the hole diameter of the through-hole part of the printed circuit board, and accordingly, the mounting part of the electrical contact pin has to be made smaller. became necessary. However, reducing the size of the mounting part of these pins with conventional structures makes cutting and bending or hollow hole machining difficult, and the mechanical strength of the legs weakens, which may cause buckling deformation during driving. .

部８に挿入した時の構成が示されている。 Referring to FIGS. 3a to 3c, the first embodiment of the present invention
The electrical connection pin according to the embodiment has an intermediate mounting portion 1 for fitting and fixing into a through-hole portion of a printed circuit board, and triangular recesses 2 are provided on two opposing sides of the mounting portion 1, respectively. 3 is provided. These recesses are alternately arranged facing each other. In order for the terminal corners 4, 5 adjacent to these triangular recesses to sufficiently abut the conductive through holes 8 of the printed circuit board, chamfers 6, 7 are formed at the opposite corners of the terminals. This constitutes an accordion-shaped electrical contact pin 9 in which the cross-sectional shape of the mounting portion 1 can be elastically deformed. The electrical contact pin 9 configured in this way is inserted into the third through-hole portion 8 of the printed circuit board before being inserted.
As shown in FIG. The positional relationship shown in FIG. 3b is satisfied, and the through-hole portion 8 can be inserted with a relatively light load without causing damage. Further, it becomes possible to accommodate slight variations in the inner diameter dimension of the through-hole portion 8. FIG. 4 shows the configuration when the electrical contact pin 9 is inserted into the through hole portion 8 of the printed circuit board 10.

る。 Furthermore, FIGS. 5 and 6 are cross-sectional views of the mounting portions of second and third embodiments of the electrical contact pin according to the present invention. This is a case where recesses 2'', 3'' and semicircular recesses 2, 3 are provided. When these are also inserted into the through-hole portion 8, they are elastically deformed under the pressure force in the direction of the arrow and come into mechanical and electrical contact with the through-hole portion 8. Note that it is also possible to provide appropriate recesses on the other two opposing sides of the mounting portion 1 of the electrical contact pin 9 to promote elastic deformation.

気接触ピンを得られる。 As explained above, the present invention employs an accordion structure in the pin mounting portion to maintain flexibility without reducing the effective rigidity as would be the case when cutting or drilling holes. The insertion force into the plate can be reduced. Further, damage to the through-hole portion of the printed circuit board can be avoided, and it can be easily manufactured by crushing with a press, etc., and an electrical contact pin with stable contact can be obtained at low cost.
