US 7,445,522 B2 · Electrode connector

Abstract

A biomedical electrode connector for coupling with a biomedical electrode of the type including an electrode base and a male terminal projecting from the electrode base is provided. The electrode connector includes a jacketed housing having an internal cavity with an electrical contact material adapted for electrical coupling relation with an electrical lead wire. The jacketed housing includes a lower member positionable adjacent the electrode and having internal surface portions defining a keyhole slot therein. The keyhole slot has a first slot portion defining a first internal dimension to permit passage of the male terminal of the electrode for reception within the internal cavity, and a second slot portion defining a second internal dimension less than the first dimension whereby, upon traversing movement of the male terminal within the internal cavity, the male terminal is secured within the internal surface portions defining the second slot portion to thereby electrically couple the electrode with the electrode connector.

Dependent claims

A biomedical electrode connector assembly for coupling with a biomedical electrode including an electrode base and a male terminal projecting from the electrode base, the electrode connector comprising:

a connector housing having electrical contact material adapted to establish an electrical coupling relation with an electrical lead wire, the connector housing including:
a lower member adapted to be positioned adjacent the electrode and having internal surface portions defining a terminal slot therein, the terminal slot having a first slot portion defining a first internal dimension adapted to receive the male terminal of the electrode and a second slot portion defining a second internal dimension less than the first internal dimension;
and
a flexible locking element depending at least radially inwardly relative to the terminal slot;
whereby, upon traversing movement of the male terminal within the terminal slot from the first slot portion to the second slot portion, the flexible locking element is adapted to flex toward the internal surface portions to permit passage of the male terminal and, thereafter, return toward a preflex state to engage the male terminal to facilitate retention of the male terminal within the second slot portion.

a connector housing having electrical contact material adapted to establish an electrical coupling relation with an electrical lead wire, the connector housing including:
a lower member adapted to be positioned adjacent the electrode;
an electrode contact tab extending in cantilever relation within the lower member and being at least partially defined by a relief slot within the lower member, the relief slot at least partially circumscribing the electrode contact tab, the electrode contact tab having internal surface portions defining a terminal slot therein, the terminal slot having a first slot portion defining a first internal dimension adapted to receive the male terminal of the electrode and a second slot portion defining a second internal dimension less than the first internal dimension;
whereby, upon traversing movement of the male terminal within the terminal slot of the electrode contact tab from the first slot portion to the second slot portion, the electrode tab is permitted to flex due, at least in part to the relief slot, to permit passage of the male terminal to facilitate retention of the male terminal within the second slot portion.
