Patent ID: 8485833

Claim:
A connector for mounting on a substrate that has through-holes formed therethrough, the connector comprising: a housing mountable on the substrate; press-fit terminals mounted in the housing, each press-fit terminal having a bulging press-fit portion projecting from the housing and disposed to be press-fit into one of the through-holes, the bulging press-fit portion defining a maximum bulging width (W 1 ); and a terminal arrangement sheet having positioning holes extending entirely through the terminal arrangement sheet in a thickness direction, the positioning holes being disposed and dimensioned for receiving portions of the respective press-fit terminals forward from the press-fit portion of the respective press-fit terminal and positioning the press-fit terminals prior to insertion into the respective through-holes, the positioning holes having diameters (W 3 ) less than the maximum bulging width (W 1 ) of the bulging press-fit portion, gap-forming slits extending entirely through the terminal arrangement sheet in the thickness direction and projecting out from opening edge areas of each of said positioning holes at locations to align with side edges of said press-fit portions corresponding to a maximum width of the respective press-fit portion, a total extending dimension (W 4 ) of the slits across the respective positioning hole exceeding the maximum bulging width (W 1 ) of the bulging press-fit portion, wherein the slits enable expansion of each of said positioning holes as the corresponding press-fit portion passes through the positioning hole.
