A connector device includes a main body having a plug section. The main body accommodates therein two contact members, a bidirectional diode-thyristor, and a distal end portion of a signal-transmission cable connected with an external electronic equipment. The two contact members are connected with two terminals of the thyristor and two conductor wires of the signal-transmission cable, to thereby obtain a modular plug with overvoltage protection. By inserting the modular plug into a modular jack, the external electronic equipment is connected with a communication line. If an overvoltage is applied to the communication line, the thyristor is rendered conductive to absorb the overvoltage, so that the electronic equipment is protected from the overvoltage. In place of designing the connector plug to hold the distal end portion of the signal-transmission cable, the connector body may be formed with a socket section which receives an external modular plug, to thereby obtain a modular adapter with overvoltage protection which is used to connecting a modular plug with a modular jack.

L'invention est un connecteur dont la carcasse porte une section d'affichage. La carcasse peut recevoir deux éléments de contact, un élément bidirectionnel diode-thyristor et l'extrémité distale d'un câble de transmission de signaux connecté à un appareil électronique externe. Les deux éléments de contact sont connectés à deux bornes du thyristor et à deux conducteurs du câble de transmission de signaux, ce qui constitue une fiche modulaire protégée contre les surtensions. En insérant cette fiche modulaire dans un jack modulaire, on connecte l'appareil électronique externe à une ligne de communication. En cas de surtension dans cette dernière, le thyristor devient conducteur et absorbe la surtension, de sorte que l'appareil électronique est protégé contre la surtension. Au lieu de connecter l'extrémité distale du câble de transmission de signaux à la fiche du connecteur, on peut incorporer une prise à la carcasse du connecteur pour y recevoir une fiche modulaire externe et obtenir ainsi un adaptateur modulaire protégé contre les surtensions que l'on peut utiliser pour connecter une fiche modulaire à un jack modulaire.
