REDUCTION OF INSERTING-EXTRACTING FORCE AND MOUNTING FORCE OF CONNECTOR FOR PRINTED BOARD

摘要

PURPOSE:To provide an inserting-extracting force and mounting force reducing method of a connector for a printed board by which inserting-extracting force and/or mounting force of the printed board can be reduced without changing a structure of the connector for a conventional printed board. CONSTITUTION:In a coaxial connector (alpha), a signal return earth current Ea is continued in common over to adjacent plug-in female type external cylinders 5 through earth layers 9 and 10 of printed boards 7 and 8 having respectively plug-in female and male type coaxial elements 1 and 2 to continue a signal current through a spring contact point S1 formed of a signal pin terminal 3 and a signal spring terminal 4 extending respectively along the central axes of plug-in female and male type external cylinders 5 and 6 to continue mutually the signal return earth current Ea through a spring contact point S2. Contact force of the spring contact point 52 is set smaller than contact force of the spring contact point 51, and inserting-extracting force between the mutual plug-in female and male type coaxial elements 1 and 2 is reduced and regulated.
