なった。The structure of the mounting part in the conventional electrical contact bottle of this type that contacts the through-hole part of the printed circuit board is a metal plate made of conductive spring material that is cut and bent.
(See FIGS. 1(a) and 2(b)), hollow holes were provided in the mounting portion to make the beam portion flexible (see FIGS. 2(a) and 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 section of the printed circuit board, and accordingly, the mounting section of the electrical contact bottle must be made smaller. became necessary.

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, on two opposing sides of the mounting portion 1, respectively. 3 is provided and 11: is provided. These recesses are alternately arranged facing each other. In order for the terminal corners 45 adjacent to these triangular recesses to sufficiently abut the conductive through-hole portions 8 of the printed circuit board, chamfered portions 6 and 7 are formed at opposite corners of the terminals. This constitutes an accordion-shaped electrical contact pin 9 in which the cross-sectional shape of the rim attachment portion 1 can be elastically deformed.

入できる。Before the electrical contact pin 9 configured as described above is inserted into the through-hole portion 8 of the printed circuit board, the dimensions of the mounting portion 1 are equivalent to the inner diameter of the through-hole portion 8, as shown in FIG. 3(C). Although the relationship is large, by inserting it into the through-hole portion 8, the flexibility of the ShearCorp ion shape allows it to be elastically deformed, and the relationship shown in FIG. 3(b) is maintained. 8 can be inserted with a relatively light load without causing damage.

3/ is shown in a sectional view of the electrical contact pin in the second embodiment of the present invention, in which when inserted into the through-hole portion 8, there is a diagonal terminal corner that is not chamfered in the direction of the arrow. Pressure force acts and compresses and deforms. FIGS. 6 and 7 also show the third and fourth electrical contact pins according to the present invention.
The cross-sectional shape of the mounting portion shows an embodiment of the present invention, in which angular recesses 2'' are arranged alternately and oppositely on two opposite sides of the contact pins.

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.

あシ、安価で接触の安定した電気接触ピンを得られる。As explained above, the present invention employs an accordion structure for the pin mounting portion, thereby increasing flexibility without reducing the effective rigidity as would be the case with cutting or drilling. Since it can be held, the insertion force of the printed circuit board can be reduced. In addition, 5- damage to the through-hole portion of the printed circuit board can be avoided, 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.
