<p>PURPOSE:To prevent a contact pin from vibrating by inserting a spring, which allows the contact pin at the pad side and the contact pin at the column side to be kept away each other, into a cylindrical pin holder together with a lubricant. CONSTITUTION:A cylindrical pin holder 5 is installed at a place where a pair of a slip ring 2a at the pad side and a slip ring 2b at the column side faces each other in a boss plate 7. Each of contact pins 4a and 4b has a projection 23 in a collar form, and the projection is housed in the contact pin holder 5. And the end portion of a conductive spring 6 is externally inserted between the contact pins 4a and 4b, each of which is energized so as to be kept away each other by the spring 6. Conductive grease G is filled in the holder 5 as a lubricant.</p> |
