Abstract
Abstract A socket and plug coupling assembly wherein the socket is a box-like frame with walls of the top and front partially removed, and has pins arranged on a bottom to extend upwardly. At the base of the pins the remaining front stub wall forms a brace in which a slope is formed to be inclined inwardly downwardly of the socket frame. The plug is shaped to be a box-like frame with openings on a bottom continuing to a front wall and the plug has contact members inside the frame openings facing frontwardly. A nail is provided at a rear end of the plug frame extending downwardly from the bottom. In a coupling action of the plug with the socket, first, the nail of the plug is obliquely contacted on the slope of the socket via a face to face approach of the plug toward the socket and then, rotating inwardly about the contact of the nail with the slope, the plug is turned to couple with the socket.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
258 words
A socket and plug coupling assembly comprising: a socket member of box-like shape having a bottom, two side walls, a rear wall, and a partial front wall adjacent the bottom forming a brace, said socket member including a plurality of contact pins mounted on the bottom and extending upwardly therewithin, said socket member being formed with an inner surface of said brace having a slope inclined downwardly toward said pins, and having at least one opening formed in the bottom adjacent said brace; and a plug member of a box-like shape and a size fitting to an interior space of said socket member, said plug member having a plurality of openings formed in a bottom and front wall thereof corresponding in position to said contact pins of said socket member, contact means affixed to a rear wall within said plug member adjacent said openings, said plug member rear wall being formed with at least one hook-like nail member extending downwardly and having a distal end portion projecting outwardly, at a position corresponding to said at least one opening in said socket member bottom; said socket and plug coupling assembly being removably assembled by moving said plug member nail obliquely in contact with said brace inner inclined surface to enter said socket member bottom at least one opening, and then turning the plug inwardly of said socket member such that said socket member contact pins enter said plurality of openings to engage the contact means therewithin, said nail distal end portion thereby engaging a bottom edge of said brace.
Claim 2
Dependent Claim
258 words
A socket and plug coupling assembly comprising: a socket member of box-like shape having a bottom, two side walls, a rear wall, and a partial front wall adjacent the bottom forming a brace, said socket member including a plurality of contact pins mounted on the bottom and extending upwardly therewithin, said socket member being formed with an inner surface of said brace having a slope inclined downwardly toward said pins, and having at least one opening formed in the bottom adjacent said brace; and a plug member of a box-like shape and a size fitting to an interior space of said socket member, said plug member having a plurality of openings formed in a bottom and front wall thereof corresponding in position to said contact pins of said socket member, contact means affixed to a rear wall within said plug member adjacent said openings, said plug member rear wall being formed with at least one hook-like nail member extending downwardly and having a distal end portion projecting outwardly, at a position corresponding to said at least one opening in said socket member bottom; said socket and plug coupling assembly being removably assembled by moving said plug member nail obliquely in contact with said brace inner inclined surface to enter said socket member bottom at least one opening, and then turning the plug inwardly of said socket member such that said socket member contact pins enter said plurality of openings to engage the contact means therewithin, said nail distal end portion thereby engaging a bottom edge of said brace.
Claim 3
Dependent Claim
49 words
A socket and plug coupling assembly as recited in claim 1, further comprising flutes formed on outer side walls of said plug member and mating flutes formed on inner side walls of said socket member, such that completion of said turning movement of the plug engages said mating flutes.
