An integral plastic fuseholder for receiving portions of a pair of in-line electrical conductors which may be connected to a non-fused electrical adapter plug. One conductor of the pair is severed within the holder to form an open connection until the connection is completed by a flat-blade insertion fuse. A pair of female electrical terminals is located within the fuseholder with each terminal connected to a different end of the severed conductor. The fuseholder has a foldable clam-shell housing formed by a pair of foldable cover sections which are joined by a centrally disposed hinge section. The housing is opened to receive the in-line electrical conductor pair, or alternatively is folded to a closed position to retain the in-line conductor pair and to create a partially enclosed cavity which forms a fuse-insert access opening opposite the hinge section. Any inserted fuse is connected in series with the conductor terminals to complete a fused conductor connection to an adapter plug through the fuseholder. A removable cap is provided to close the fuse-insert access opening.

Fuseholder

An electrical coaxial jack connector adapted for electrical interconnection with a mating plug-type coaxial connector. The coaxial jack connector has an integral molded plastic body from which external connecting wires project to form a unitary cable connector. The jack-connector body is subdivided into three body sections, namely, a contact-housing section, a grip section, and a wire strain-relief section. A contact mounting board divides the contact-housing section from the grip section. A coaxial male-pin contact and a peripheral leaf-spring contact project from a front surface of the mounting board into an access cavity defined by a cylindrical wall which forms the contact-housing body section. This cylindrical wall is formed with an internal recess or groove which is located adjacent to and in alignment with the leaf-spring contact. This recess serves as a receptacle, at least in part, for the leaf-spring contact in response to leaf-spring deflecting movements caused by the mating insertion of a plug coaxial connector into the jack connector-housing body section.
