Abstract
Abstract A multifunction concentric plug comprises a large-size concentric plug portion and a small-size concentric plug portion. When the portions are combined, a sleeve of relatively small-size concentric plug portion is arranged in a hollow of a sleeve of the large-size concentric plug portion so that the sleeve of the large-size concentric plug portion is aligned with the sleeve of the small-size concentric plug portion. The tip of the small-size concentric plug portion electrically contacts a core conductor of the large-size concentric plug portion. A combining means is provided in knobs of the large-size and small-size concentric plug portions whereby the large-size and small-size concentric plug portions can be securely combined with each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
259 words
In a prior art multifunction concentric plug assembly formed of a large-size concentric plug portion and a small-size concentric plug portion, each of said plug portions having a knob, sleeve extending from the knob, and a tip conductor at an end of the sleeve opposite the knob the small-size plug having a small sleeve and the large-size plug having a large sleeve, and wherein the small-size plug portion plugs into a receiving aperture of the large-size plug portion to form an assembly of given overall length, wherein the improvement comprises: the sleeve of the large-size plug portion being hollow and the tip conductor having a portion positioned in and at the end of said hollow so as to form a free space in said hollow defined by an end of said tip conductor within the sleeve and walls of the hollow said free space extending to an end of said sleeve at the knob; the substantially entire sleeve of the small-size plug portion being received within said free space and the tip of the small-size plug portion being in electrical contact with the large-size plug tip conductor when assembled with the large-size plug portion; a first combining means in one of said knob and a second combining means formed in the other of said knob, said large-size plug portion and small-size plug portion being combined with each other by said first and second combining means; and a length of the combined sleeve assembly being substantially shorter than said given length of assembled prior art large-size and small-size plug portions.
Claim 2
Dependent Claim
259 words
In a prior art multifunction concentric plug assembly formed of a large-size concentric plug portion and a small-size concentric plug portion, each of said plug portions having a knob, sleeve extending from the knob, and a tip conductor at an end of the sleeve opposite the knob the small-size plug having a small sleeve and the large-size plug having a large sleeve, and wherein the small-size plug portion plugs into a receiving aperture of the large-size plug portion to form an assembly of given overall length, wherein the improvement comprises: the sleeve of the large-size plug portion being hollow and the tip conductor having a portion positioned in and at the end of said hollow so as to form a free space in said hollow defined by an end of said tip conductor within the sleeve and walls of the hollow said free space extending to an end of said sleeve at the knob; the substantially entire sleeve of the small-size plug portion being received within said free space and the tip of the small-size plug portion being in electrical contact with the large-size plug tip conductor when assembled with the large-size plug portion; a first combining means in one of said knob and a second combining means formed in the other of said knob, said large-size plug portion and small-size plug portion being combined with each other by said first and second combining means; and a length of the combined sleeve assembly being substantially shorter than said given length of assembled prior art large-size and small-size plug portions.
Claim 3
Dependent Claim
52 words
An assembly according to claim 1 in which said first combining means is a projection formed in the inside wall of said knob, and said second combining means is an L-shaped recess formed in the outer circumferential surface of said other knob, said projection and L-shaped recess being engageable with each other.
Claim 4
Dependent Claim
52 words
An assembly according to claim 1 in which said first combining means is an L-shaped recess formed in the inside wall of said knob, and said second combining means is a projection formed in the outer circumferential surface of said other knob, said projection and L-shaped recess being engageable with each other.
Claim 5
Dependent Claim
31 words
An assembly according to claim 1 in which said tip of the small-size concentric plug portion of said sleeve thereof are received in said hollow of the large-size concentric plug portion.
Claim 6
Dependent Claim
50 words
An assemby according to claim 1 wherein the tip conductor of the large-size plug portion is mounted in an insulating collar at the end of the sleeve and has an end surface in direct mechanical and electrical contact with a tip of the tip conductor of the small-size plug portion.
Claim 7
Dependent Claim
17 words
An assembly according to claim 1 wherein the sleeve of each of the plug portions is cylindrical.
Claim 8
Dependent Claim
32 words
An assembly according to claim 6 wherein the tip conductor of the small-size plug portion abuts against the end of the tip conductor of the large-size plug portion within the free space.
Claim 9
Dependent Claim
20 words
An assembly according to claim 1 in which said first and second combining means are screw engageable with each other.
Claim 10
Dependent Claim
14 words
An assembly according to claim 8 in which said knobs are made of metal.
