FIG. 3 is a plan view of this connector. According to the figure, this connector C includes a connecting body 30 and a molded base resin 6.
6', the connecting body 30 is formed by pressing a thin metal plate, and each end has narrow linear legs 3 and 3' for inserting a printed circuit board, and has chevron-shaped ribs along the entire length to prevent deformation. processed into a shape. Reference numeral 4.4' denotes a connecting part that connects a plurality of connecting bodies 30 to each other at a constant pitch, and 5 denotes a narrow connecting part that connects the leg parts 3.3' at both ends, and is flexible. There is.

となるように構成されている。The narrow straight leg portions 12 of the terminal portion 1l, which are continuously provided at both ends of the connecting body 10 formed by pressing a thin metal plate, are provided with chevron-shaped ribs 13 over the entire area to prevent the terminal from deforming. It is being This chevron rib 13 is the wide flat part 1 of the terminal.
4 up to 15 are provided. A molded base portion 18 is formed around the wide flat portion l4, except for the leg protrusion example 16, so as to be embedded and fixed in a molded resin wall portion l7 provided between the respective terminals. Further, the end surface 19 of the molded resin wall portion 17 protrudes beyond the stepped portion 20 between the narrow linear leg portion l2 and the wide flat portion 14, and this end surface 19 comes into contact with the printed circuit board when the printed circuit board is mounted. It is configured to be a contact part.

ものである。Since the chevron-shaped ribs are provided over the entire area of the narrow-width $11-shaped leg portion and halfway through the wide flat portion, the deformation strength of the terminal is increased. In particular, since the chevron-shaped ribs 13 are also provided on the stepped portion 20 between the narrow linear leg portion and the wide flat portion, which has been a problem in the past, the deformation strength of the terminal is significantly improved compared to the conventional one. Reference numeral 21 denotes a connecting machine section that connects a plurality of connecting bodies 10 to each other at a constant pitch, and after the connecting bodies 10 are insert-molded within the molded base section 18, the connecting machine section 21
is cut to form the connector for connecting the printed circuit board shown in FIG.
