Abstract

A structure of electrically connecting a snap electrode for medical purposes is easily attached/detached to/from various monitoring pads attached to a human body to measure electrocardiogram (ECG), electromyogram (EMG), brain wave and nervous system signals and electrically connected to medical equipment, to an electric wire using a pressing method instead of welding. The connecting structure of a snap electrode and an electric wire includes a body having a convex portion, which is formed on the top of the body and has a groove formed on the circumference thereof, in which a combining part is fitted, and the combining protrusion having a ring shape and including a predetermined number of elastic fixing pieces protruded from the inner side thereof and a pair of first pressing pieces protruded from one side thereof and combined with an electric wire. A combining protrusion of a pad is inserted into the body.

Claims

1. A connecting structure of a snap electrode for medical purposes and an electric wire, comprising:

a body on which a convex portion comprising a groove formed on the circumference thereof, in which a combining part is fitted, is formed;

a base comprising a protrusion housing formed at the center thereof and spring slits formed at both sides of the protrusion housing, into which press springs are inserted; and

the combining part comprising a ring shape and comprising a predetermined number of elastic fixing pieces protruded from the inner side thereof and a pair of first pressing pieces protruded from one side thereof and combined with the electric wire.

2. The connecting structure of a snap electrode for medical purposes and an electric wire of claim 1, wherein the elastic fixing pieces are bent upward at a predetermined angle or curved with a predetermined curvature.

3. The connecting structure of a snap electrode for medical purposes and an electric wire of claim 1, further comprising second pressing pieces formed at one side of the combining part configured to press and fix a coat of the electric wire.

4. The connecting structure of a snap electrode for medical purposes and an electric wire of claim 1, further comprising a case covering the body such that the body and a wire connecting part are not exposed to the outside.

5. The connecting structure of a snap electrode for medical purposes and an electric wire of claim 1, wherein upper cut faces of the spring slits formed at both sides of the protrusion housing are cut in a curved shape.

6. A method of forming a connecting structure of a snap electrode for medical purposes and an electric wire, the method comprising:

forming a body on which a convex portion comprising a groove on the circumference thereof, in which a combining part is fitted;

forming a base comprising a protrusion housing at the center thereof and spring slits at both sides of the protrusion housing, into which press springs are inserted; and

forming the combining part comprising a ring shape and comprising a predetermined number of elastic fixing pieces protruded from the inner side thereof and a pair of first pressing pieces protruded from one side thereof and combined with the electric wire.

7. The method of claim 6, wherein the elastic fixing pieces are bent upward at a predetermined angle or curved with a predetermined curvature.

8. The method of claim 6, further comprising forming second pressing pieces at one side of the combining part configured to press and fix a coat of the electric wire.

9. The method of claim 6, further comprising forming a case covering the body such that the body and a wire connecting part are not exposed to the outside.

10. The method of claim 6, wherein upper cut faces of the spring slits at both sides of the protrusion housing are cut in a curved shape.
