摘要： A modular jack incorporating a varistor. The varistor reduces noise and surge (abnormal voltage) entering the modular jack, and thereby an electronic appliance such as a telephone connected with the modular jack is not affected by the noise and surge. The varistor is electrically connected between at least a pair of contact leads. Alternatively the varistor is electrically connected between the pair of contact leads and a grounding terminal. Further, the modular jack incorporates a common mode choke coil so as to obtain a common mode noise reduction effect.

摘要： A retainer for insert-retaining a plurality of pin terminals includes a ferrite member having an aligned arrangement of through holes formed at insertion positions of the pin terminals and a resin member covering one surface of the ferrite member. The resin member also has an aligned arrangement of holes for receiving the pin terminals. The ferrite member functions as a filter element to reduce noise. Thin portions are formed along the inner circumferential surfaces of resin member defining the holes. The thin portions are deformed or fractured by the insertion of the pin terminals, and then each deformed or fractured portion is sandwiched between the inserted pin terminal and the inner circumferential surface to thereby elastically engage the pin terminal, resulting in the retainer being secured to the pin terminals in a manner which prevents the terminals from shifting in position.

摘要： A first bypass-type condenser for normal mode noise is connected between the input terminals of a pair of signal paths and a pair of further bypass-type condensers for common mode noise are each connected between a respective one of the signal paths and ground. The pair of further bypass-type condensers each comprise a three-terminal condenser having a pair of lead terminals each provided with a bead core thereon, whereby noise passing through the line filter can be effectively eliminated, while also eliminating spurious LC resonance effects at ultra-high frequencies.
