专利汇可以提供Telephone modular jack专利检索,专利查询,专利分析的服务。并且PURPOSE: To obviate the necessity of mounting an impedance element on the outside so as to facilitate the execution of works by installing a substrate, where an impedance element for circuit test is mounted, in a housing, and connecting both ends of the slumped once element to terminal blocks.
CONSTITUTION: An impedance element 73 is provided so that it can inspect whether it conducts electricity when alternate currents are let flow from a station side, to test wire breaking, etc., of telephone circuits. In a printed board 71 where this impedance element 73 is mounted are provided a couple, left and right, of connection holes 74 corresponding to the conductive pattern connected to both ends of the impedance element 73. The printed board 71 is arranged in the space between both partitions walls 13, and a terminal block 4 and the printed board 71 are connected electrically through a connection plate 72 arranged along the inner periphery of a body 1. This way, the impedance element 73 for circuit test is installed in a housing A, and there is no necessity to mount it on the outside.
