<p>PROBLEM TO BE SOLVED: To increase the reliability of transmission, without causing transmission failure due to the accumulation of dust by installing a cover section covering a terminal of a modular jack. SOLUTION: An adaptor is connected to a modular jack and then a dust protective cover, having a twisted paired cable L1 passed through it, is mounted on the modular jack connected by the adaptor. The dust protective cover controls the rotation of levers 12d, 12e and, at the same time, covers a terminal 12f of a cable. Therefore, dust which has entered a box 13 from in a wall does not accumulate on the terminal 12f of the cable, and the reliability of transmission can be increased without causing transmission failures due to the accumulation of dust.</p> |
