<p>In a conductive contact unit, the base-side end section of a compression spring which urges a contact itself or a needle-like contact is housed in a supporting hole bored into a substrate. One end of the internal conductor of the substrate is exposed at the bottom of the supporting hole and the exposed part of the conductor is electrically connected to the base-side end section of the compression spring. Therefore, no electrical connector is required and the electrical resistance between the internal conductor of the substrate and contact is minimized. In order to achieve excellent electrical contact, it is possible to solder the base-side end section of the compression spring to the exposed part of the internal conductor having a flat section or recessed section.</p> |
