Abstract
Abstract A combination power connector with in-line fuse holder is disclosed. The structure includes a power connector assembly wherein a replaceable fuse is interposed in the power line and a two-piece jack assembly in the ground line. Disconnecting the connector assembly also facilitates the replacement of a fuse, if necessary. The structure includes a twist or retainer lock ring overlying respective halves of the connector assembly and releasably locks the respective connector components in the assembled relation. A pliant, two-piece insulating cover completes the assembly.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
An improved power connector arrangement with self-contained in-line fusing device, comprising in combination: a pair of substantially identical connector elements for interfitting each with the other, each of said connector elements having a forward reduced portion and a pair of laterally displaced but longitudinally extending openings therein, one of said openings being capable of retaining a glass tube fuse device therein and the other of said openings being capable of retaining respective portions of a jack assembly, said connector elements further including a pair of up-raised projections on the surfaces thereof; and a split-ring retainer member having a pair of slots at one end thereof for overfitting and capturing said projections on one of said connector elements, said retainer having a pair of L-shaped openings at the other end thereof for permitting the insertion of said projection of said other connector element and the rotation thereof laterally to effect a locking action.
Claim 2
Dependent Claim
152 words
An improved power connector arrangement with self-contained in-line fusing device, comprising in combination: a pair of substantially identical connector elements for interfitting each with the other, each of said connector elements having a forward reduced portion and a pair of laterally displaced but longitudinally extending openings therein, one of said openings being capable of retaining a glass tube fuse device therein and the other of said openings being capable of retaining respective portions of a jack assembly, said connector elements further including a pair of up-raised projections on the surfaces thereof; and a split-ring retainer member having a pair of slots at one end thereof for overfitting and capturing said projections on one of said connector elements, said retainer having a pair of L-shaped openings at the other end thereof for permitting the insertion of said projection of said other connector element and the rotation thereof laterally to effect a locking action.
Claim 3
Dependent Claim
63 words
An improved power connector arrangement with self-containing in-line fuse device in accordance with claim 1 wherein said locking action is provided by tab members extending laterally within said L-shaped openings which are spring biased into engagement with said projections of said other of said connector elements by spring means contained within the cavity formed by said connector elements that house said fuse element.
Claim 4
Dependent Claim
52 words
An improved power connector arrangement with self-contained in-line fuse device in accordance with claim 1 wherein said connector arrangement includes a pliant cover of insulating material overlying each of said connector elements, one of said covers inserting into the other of said covers a given distance upon engagement of said connector elements.
