PURPOSE:To eliminate the interference between probers by the shield effect of a metal, by arranging and fixing many insulating chips, each of which two probers are fitted and fixed to, at tips of probers arranged in a small area. CONSTITUTION:A metallic plate 21 is arranged above a crystal oscillator 1, and a long hole 22 is provided in the metallic plate 21 in a position above the contacting part of the crystal oscillator group 1 in accordance with the arrangement of the contacting part, and many insulating chips 30 consisting of Teflon materials are arranged close in this long hole 22, and tips of every two probers 10 connected to an oscillating circuit are inserted to the insulating chip 30 and are fixed with an adhesive. For the purpose of fixing insulating chips 30 arranged on the metallic plate 21 in this manner, a partial part 24 of every two probers 10 is provided to arrange a press plate 23 on the metallic plate 21; and in this case, the part including a shield mateial 15 of probers 10 is inserted into the metallic press plate 23, thereby eliminating the floating capacity between probers 10. |
