Abstract
Abstract A fixture for use in establishing electrical contact between a banana plug mounted on a cable and a snap fastener on a disposable skin electrode comprises a bottom flange provided with a sleeve adapted to receive the banana plug. A resiliently expandable through hole formed at the bottom of the fixture makes it possible to snap the fixture over the snap fastener of the skin electrode, with the through hole being of length so that the snap fastener will protrude into the passage and establish electrical contact with a banana plug inserted therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A fixture for use in establishing electrical connection between a banana plug mounted on a cable and a metal snap fastener on a disposable skin electrode, characterized in that said fixture comprises a body consisting essentially of elastic plastic material having formed therein a resiliently expandable opening means for receiving a metal snap fastener and a passage means formed in said body substantially perpendicular to the axis of and in communication with said opening means and being open at both ends for receiving a banana plug, said opening means being of such extent in the axial direction and located relative to said passage means that a metal snap fastener when applied to said fixture extends through said opening means and protrudes into the passage means and is in direct electrical contact with a banana plug when a banana plug is inserted into either end of the passage means and wherein said fixture can rotate about the metal snap fastener when the metal snap fastener is received in said opening means.
Claim 2
Dependent Claim
170 words
A fixture for use in establishing electrical connection between a banana plug mounted on a cable and a metal snap fastener on a disposable skin electrode, characterized in that said fixture comprises a body consisting essentially of elastic plastic material having formed therein a resiliently expandable opening means for receiving a metal snap fastener and a passage means formed in said body substantially perpendicular to the axis of and in communication with said opening means and being open at both ends for receiving a banana plug, said opening means being of such extent in the axial direction and located relative to said passage means that a metal snap fastener when applied to said fixture extends through said opening means and protrudes into the passage means and is in direct electrical contact with a banana plug when a banana plug is inserted into either end of the passage means and wherein said fixture can rotate about the metal snap fastener when the metal snap fastener is received in said opening means.
Claim 3
Dependent Claim
35 words
A fixture according to claim 1, characterized in that said body is in the form of a sleeve having a substantially planar flange in which the opening means for receiving the snap fastener is provided.
Claim 4
Dependent Claim
27 words
A fixture according to claim 2, characterized in that the substantially planar flange is formed with flange parts extending outwardly from adjoining side walls of the sleeve.
Claim 5
Dependent Claim
72 words
A fixture according to claim 1, characterized in that the opening means for receiving a metal snap fastener is located relative to the passage means for receiving the banana plug so that the metal snap fastener when so received is in direction electrical contact with a side of the banana plug at a point adjacent a base of the the banana plug when the banana plug is received in the passage means.
Claim 6
Dependent Claim
52 words
A fixture according to claim 1 characterized in that the axial length of the passage means is less than a length of resilient plug segments of the banana plug so that the tip of the banana plug protrudes beyond the passage means when the banana plug is received in the passage means.
