<p>A conductive contact has a conductive needle and a needle guide hole formed in a plate consisting of a high-strength material such as metal and thus improves the positioning accuracy of the needlepoint by strengthening that portion of the holder where the needle guide hole is opened. If an available conductive metal is used as a high-strength material, an insulating film is formed inside the needle guide hole that guides the sliding needle, so that insulation is secured. In addition, by forming the plate from a conductive material, forming an insulating film inside a through hole for guiding the needle and receiving a coil spring, and covering the holder with an insulating film, the conductive needle and the compressive coil spring in the through hole are shielded electromagnetically if the plate is grounded, with the result that the effects of noises decrease.</p> |
