Abstract

Abstract A connector includes a hollow prong, a grounding shell, an insulation base, and an electrical core. One end of the prong is centrally accommodated in the base and the grounding shell is peripherally mounted on the base with mounting tabs of the grounding shell engaging with notches of the base and thereby spacing the prong and the grounding shell apart. The electrical core has two wires. One of the wires is soldered to one of the mounting tabs and the other wire is soldered to the prong through an opening of the base.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 251 words
A connector comprising: a hollow central prong having a closed end and an open end; a hollow cylindrical grounding shell comprising a plurality of mounting tabs including a first tab, protruding axially from one end of the grounding shell and being equally spaced around periphery of said one end, said first tab including a hole therein a base comprised of insulation material, including (i) a top plate having a circular protrusion projecting from an upper surface thereof, and a plurality of notches equally spaced around a periphery thereof, the protrusion having an outer diameter which is equal in size to an inner diameter of the grounding shell but smaller than a diameter of the top plate for mounting the grounding shell onto the base such that the tabs engage the notches, and (ii) a stud extending from a lower surface of the top plate, said stud having a lateral opening in an upper periphery thereof, wherein said base includes a cylindrical recess which extends through a central portion of the top plate and to said stud such that the lateral opening is in communication with said cylindrical recess, said cylindrical recess having a peg centrally located therein thereby defining an annular space receiving the open end of the central prong; and an electrical core having two wires, one of the wires extending through the lateral opening and being soldered to the central prong, the other wire extending through the hole in the first tab and being soldered to the first tab.
Claim 2
Dependent Claim 251 words
A connector comprising: a hollow central prong having a closed end and an open end; a hollow cylindrical grounding shell comprising a plurality of mounting tabs including a first tab, protruding axially from one end of the grounding shell and being equally spaced around periphery of said one end, said first tab including a hole therein a base comprised of insulation material, including (i) a top plate having a circular protrusion projecting from an upper surface thereof, and a plurality of notches equally spaced around a periphery thereof, the protrusion having an outer diameter which is equal in size to an inner diameter of the grounding shell but smaller than a diameter of the top plate for mounting the grounding shell onto the base such that the tabs engage the notches, and (ii) a stud extending from a lower surface of the top plate, said stud having a lateral opening in an upper periphery thereof, wherein said base includes a cylindrical recess which extends through a central portion of the top plate and to said stud such that the lateral opening is in communication with said cylindrical recess, said cylindrical recess having a peg centrally located therein thereby defining an annular space receiving the open end of the central prong; and an electrical core having two wires, one of the wires extending through the lateral opening and being soldered to the central prong, the other wire extending through the hole in the first tab and being soldered to the first tab.
Claim 3
Dependent Claim 46 words
The connector as claimed in claim 1, wherein a peripheral wall of the central prong is laterally pressed against the peg in the opening, thereby forming an indentation in the peripheral wall such that said one of the wires is securely soldered onto the central prong.
