Techniques and apparatuses for forming electrical connection are presented in which an apparatus may include an in-line fuse having terminals comprising terminal exterior surfaces and terminal recesses, and electrical cables comprising a conductor and a insulation sleeve and having an exposed portion and an unexposed portion. The exposed portion of an electrical cable is at least partially inserted into a respective terminal recess of the in-line fuse. The apparatus may further comprise one or more temperature-activated sealing members that circumferentially surround and form a seal against portions of the terminal exterior surfaces of the in-line fuse and portions of the insulation sleeves of the electrical cables. The apparatus may also comprise an inner mold encapsulating the in-line fuse and at least partially of the one or more temperature-activated sealing members, and an outer mold encapsulating the inner mold.
