Abstract

A belt connector is provided. The belt connector is configured to electrically connect a conductor of an electrode belt to a male portion of a snap connector electrode connected to a biometric device. The belt connector includes a frame, a fastener, and an engaging member. The frame includes a receiving hole having radial flexibility. The receiving hole is configured to receive and fasten the frame to a protrusion of the male portion of the snap connector electrode. The fastener is configured to fasten the frame to a first end of the electrode belt. The engaging member is adjacent to the receiving hole and engages the conductor of the electrode belt by the conductor passing through the receiving hole. When the male portion of the snap connector electrode penetrates the receiving hole, the conductor is forced into contact with a lateral surface of the male portion of the snap connector electrode.

wherein

the first elongated member and the second elongated member further define a first slot extending from the receiving hole,

the first elongated member and/or the second elongated member provide a radial flexibility to the receiving hole, and

the first elongated member engages the conductor of the electrode belt by the conductor extending into the receiving hole such that the conductor is in electrical contact with the protrusion of the snap connector electrode upon penetration of the protrusion into the receiving hole.

2. The electrode belt connector according to claim 1, wherein the first elongated member and the second elongated member are arranged generally in a first plane, and

the first elongated member is configured to engage the conductor of the electrode belt by at least an end portion of the conductor extending through the receiving hole from a first side of the first plane to a second side of the first plane, the first side of the first plane being opposite from the second side of the first plane, such that when the protrusion of the snap connector electrode penetrates the receiving hole, the end portion of the conductor is forced into physical contact with at least a lateral surface of the protrusion of the snap connector electrode.

3. The electrode belt connector according to claim 1, wherein the radial flexibility provides the force that forces the conductor into physical contact with at least a lateral surface of the protrusion of the snap connector electrode when the protrusion of the snap connector electrode penetrates the receiving hole.

4. The electrode belt connector according to claim 1, wherein an end portion of the conductor of the electrode belt is at least partially wrapped around the first elongated member at least once.

5. The electrode belt connector according to claim 1, wherein the end portion of the conductor of the electrode belt is wrapped around the first elongated member such that an end portion of the conductor passes from the first side of the first plane to the second side of the first plane two or more times.

6. The electrode belt connector according to claim 1, wherein the plastic frame is a molded plastic frame.

7. The electrode belt connector according to claim 1, further comprising a shield member arranged on a rear side of the plastic frame, the shield member being arranged generally in a second plane, the second plane being parallel to the first plane, wherein the shield member is configured to electrically shield the conductor of the electrode belt and an end portion of the conductor from the rear side exterior of the belt connector.

8. The electrode belt and the belt connector of claim 7, wherein

said shield member includes a sheet member extending from the plastic frame, and

the sheet member is configured to be folded over onto the rear side of the frame to cover the rear side of the receiving hole and engaged conductor.

9. The electrode belt connector according to claim 1, wherein a second slot extends from the receiving hole, the second slot extending generally from an opposite side of the receiving hole than the first slot, and the radial flexibility is provided in part by the second slot.

10. The electrode belt connector according to claim 9, wherein the radial flexibility is provided in part by the second slot.

11. The electrode belt connector according to claim 1, wherein the radial flexibility provided by the first elongated member and/or the second elongated member imparts a tension force transverse to a longitudinal axis of the first elongated member and/or the second elongated member upon penetration of the protrusion of the snap connector electrode into the receiving hole.

12. The electrode belt connector according to claim 1, further comprising a cover enclosing the frame, wherein

the cover includes a hole overlapping the receiving hole of the frame, or

the cover is configured to be readily perforated by pressing the belt connector onto the protrusion of the snap connector electrode.

13. The electrode belt connector according to claim 12, wherein the cover includes a folded paper, a plastic sticker, a fabric sticker, a plastic envelope, or a textile envelope.

14. The electrode belt connector according to claim 1, wherein the fastener portion includes a slot with a row of teeth, pins, or hooks that extend transverse to the belt direction, the row of teeth, pins, or hooks being configured to engage an end portion of the electrode belt.

15. The electrode belt connector according to claim 1, wherein the belt connector comprises an adjustment slot with teeth, pins, or hooks, and

wherein a loop of desired length of the belt can be inserted through the adjustment slot, to adjust and fix the length of the electrode belt.
