Abstract: A current resistive terminal block for connection to outer pin segment means projecting outwardly from a body member of a hermetic terminal assembly sealed in a housing wall, the terminal block including a main channel means to protect the outer pin segment means and diffuse possible leakage from the terminal assembly and subchannel means to encase and secure fused lead end wire connection means for the outer pin segment means.

Abstract: A hermetic terminal assembly for a housing including a fuse-like area positioned in the outer pin segment of a terminal pin extending in sealed relation through the body member of the terminal assembly which body member can be sealed to a housing wall, the fuse-like area in the outer pin segment being covered with a thermally decomposable coating which in the event of decomposition includes an arc suppressant. A pin guard and lead wire end connection securing device is provided to protect the outer pin segment and to secure the lead wire end connection thereto.
