ABSTRACT:
An RF connector has an overrated fuse located therein which is electrically connected in series with the center conductor. An overrated fuse is utilized because a fuse rated to give the desired protection is undesirable due to the resistance caused by its small diameter. To obtain the desired protection with the overrated fuse, current shunting means, such as diodes, are mounted within the RF connector and are electrically connected between the outer and inner conductors. The current shunting means are positioned within the RF connector to present minimum inductance to the RF circuit. The operation of the fused RF connector is such that when the power applied to the connector exceeds a predetermined amount, the current shunting means conduct the excess current to ground to provide protection to the associated equipment until the input power is sufficient to blow the overrated fuse.
