Abstract

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.

Dependent claims

A connector device with overvoltage protection, comprising:

a main body having a plug section adapted to be detachably inserted into a modular jack which has two socket contacts electrically connected individually to two conductor wires of a first signal-transmission cable;
two first contact members disposed in said plug section and electrically connected individually to said two socket contacts when said plug section is inserted into said modular jack, said two first contact members being connected or adapted to be connected respectively to two conductor wires of a modular cable of a second signal-transmission cable which is connected or adapted to be connected with external electronic equipment;
wherein each of said two conductor wires of said modular cable includes an insulator which covers the respective conductor wire, and wherein each of said first contact members has a contact pin which breaks said insulator and comes in contact with a respective one of said conductor wires;
and
an overvoltage absorption solid-state device disposed in said main body and having two terminals which are electrically connected individually to said two first contact members.
