Abstract
There is disclosed a portable electronic instrument () including a case (), at least one electronic unit () housed inside the case, and at least a first input and/or output terminal (A; B) accessible from the exterior of the case and including an electrically conductive element () which is mounted so as to be mobile with respect to the case. The input and/or output terminal is adapted to be electrically connected to an input and/or output terminal () of said electronic unit via a transmission line (I/O; I/O) and for allowing transmission of electric signals on the transmission line through the connecting element. The connecting element can occupy a first or second position in which the input and/or output terminal is respectively uncoupled from or coupled to the input and/or output terminal of the electronic unit. The portable electronic instrument further includes a transmission gate (TG; TG) inserted on the transmission line between the input and/or output terminal and the input and/or output terminal of the electronic unit, said transmission gate having a transmitting and non-transmitting state allowing the input and/or output terminal to be respectively coupled to or uncoupled from said input and/or output terminal of the electronic unit. A protective element (TVS, TVS) against electrostatic charges is also inserted on the transmission line between the input and/or output terminal and the transmission gate.
