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.

2. The electrode belt and the belt connector of claim 1, wherein the belt connector further comprises a shield member which is arranged on a rear side of the frame to electrically shield the conductor of the electrode belt from the rear side exterior of the belt connector.

3. The electrode belt and the belt connector of claim 2, wherein

said shield member is a sheet member extending from the frame, and

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

4. The electrode belt and the belt connector of claim 1, wherein radial flexibility of the receiving hole is achieved by one or more slot extending from the hole.

5. The electrode belt and the belt connector of claim 1, wherein the receiving hole and one or more slot are formed by at least one elongated member having flexibility transverse to its longitudinal axis, thus imparting flexibility to the width of the hole.

6. The electrode belt and the belt connector of claim 1, wherein the belt connector comprises a cover enclosing the frame,

wherein the cover defines a cover hole that overlaps the receiving hole of the frame, or the cover can be readily perforated by pressing the connector onto a male fastener which fits the receiving hole of the frame.

7. The electrode belt and the belt connector of claim 6, wherein the cover is selected from the group consisting of a folded paper, plastic or fabric sticker, a plastic envelope and a textile envelope.

8. The electrode belt and the belt connector of claim 1, wherein the fastener comprises a slot with a row of teeth, pins or hooks transverse to the belt direction, to engage a belt end.

9. The electrode belt and the belt connector of claim 1, wherein the fastener comprises a ridge member or row of pins which lies transverse to the belt direction and to which a belt end can be fastened onto with heat melting or gluing.

10. A process for making an electrode belt with a biometric belt connectors, the method comprising:

placing an end of a flexible electrode belt with an incorporated wire onto a belt connector frame as defined in claim 9, in the suitable direction in which it is to be fastened onto the connector, such that a portion of the belt end extends beyond the ridge member or row of pins,

pressing a heat element, ultrasonic hot body onto the belt and ridge member or row of pins, and through the action of the heat, shearing an end piece of the belt but leaving intact the incorporated wire within the end piece, thus revealing an end of the wire,

through the action of heat from the heat element or another heat element, fastening by heat melting the belt to the ridge, and

fastening the wire end to a member adjacent to the hole of the connector frame, such that the end is in electrical contact with the hole and comes in electrical contact with a conducting male snap fastener inserted in the hole.

11. The process of claim 10, wherein two heating steps are applied, a first heating step to shear an end piece of the belt and a second heating step to fastening the belt to the connector frame.

12. The process of claim 10, further comprising enclosing the frame with a cover and fastening the cover.

13. The electrode belt and the belt connector of claim 1, wherein the belt connector comprises an adjustment slot with teeth, pin or hook members, wherein a loop of desired length of the belt can be inserted through the adjustment slot, to adjust and fix the length of the belt.

14. The electrode belt and the belt connector of claim 1, wherein the belt is a flexible textile belt with an electrode wire interwoven in the belt or laminated between two layers of the belt.

15. The electrode belt and the belt connector of claim 1, wherein the conductor of the electrode belt is an electrode wire.
