PROBLEM TO BE SOLVED: To shut off interference to the radiation leakage of a transmission signal, to prevent the interference due to outside noise, by press-forming a first metallic case, to be mounted on an adaptor socket main body, and a second metallic case, to be integrally formed. SOLUTION: A metallic front case 25 is fittedly engaged with the connecting port side surface of the main body 24 of an adaptor set, constituted of parallel terminal sets 22 inserted into the hole of a circuit plate 21 to be soldered, a circuit plate 21, a contact terminal 23, and a telephone socket main body 24. First and second metallic case 3 and 2 integrally formed by press-molding, are covered on the exposed portion of the adaptor set. An external connecting cable 5, passed through a wire-passing hole 6 formed on the case 3, is connected to the terminal set 22, to provide an opening 9, into which a telephone socket 1 is penetrated, on the case 2. Locking projections 27 and 28, provided on the cases 3 and 2, are locked to locking holes 271 and 281, provided on the main body 24, to fix the case 3 and 2 to the main body 24. |
