Abstract

A belt connector for electrically connecting an electrode belt to a biometric device to be carried on a human or animal body. The belt connector is made from one single piece which can be economically manufactured in order to function as a single-use consumable, to be used with a matching biometric device. The connector comprises a molded plastic frame having a shaped circular or semi-circular hole with radial flexibility to function as a female snap button fastener for receiving and fastening on the front side of the frame a male snap protrusion. The belt connector further comprises fastening means for fastening to the frame a belt end of said electrode belt, and a member adjacent to said snap fastener hole to engage an electrode wire end electrically connected to said belt such that said end is in contact with said hole and comes in electrical contact with a conducting male snap fastener inserted in said hole. The belt connector and belt is configured such that a person wearing the belt under operation is insulated from current running through the belt, in order to meet existing standards for medical devices.

Claims

1. A biometric belt connector for electrically connecting an electrode belt to a biometric device to be carried on a human or animal body, the belt connector comprising:

(a) a molded plastic frame having a front side and a rear side,

(b) said frame having a receiving hole with radial flexibility to function as a female snap button fastener for receiving and fastening on the frame a male snap protrusion,

(c) fastening means for fastening to the frame a belt end of said electrode belt, and

(d) a member adjacent to said hole to engage an electrode wire end electrically connected to said belt such that said end is in contact with said hole and comes in electrical contact with a conducting male snap fastener inserted in said hole.

2. The belt connector of claim 1, further comprising a shield member which is arranged on the rear side of said frame to electrically shield the wire from the rear side exterior of the belt connector.

3. The belt connector of claim 1, wherein radial flexibility of said receiving hole is achieved by one or more slot extending from said hole.

4. The belt connector of claim 3, wherein said 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.

5. The belt connector of claim 2, wherein said shield member is a sheet member extending from the frame, which sheet member is configured to be folded over onto the rear side of the frame to cover the back side of said receiving hole and engaged wire.

6. The belt connector of claim 1, comprising a cover enclosing the frame, which cover either includes a hole overlapping the receiving hole of the frame, or can be readily perforated by pressing the connector onto a male fastener which fits the receiving hole of the frame.

8. The belt connector of claim 1, wherein said fastening means comprise a slot with a row of teeth, pins or hooks transverse to the belt direction, to engage a belt end.

9. The belt connector of claim 1, wherein said fastening means comprise a ridge member (12) 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. The belt connector of claim 1, comprising an adjustment slot with teeth, pin or hook members, through which slot a loop of desired length of said belt can be inserted, to adjust and fix the length of the belt.

11. A process for making an electrode belt with biometric belt connectors, 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 said ridge member or row of pins,

pressing a heat element, ultrasonic hot body or other means of heat transfer onto said 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 said end piece, thus revealing an end of said wire,

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

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

12. The process of claim 11, 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

13. The process of claim 11, further comprising enclosing the frame with a cover and fastening the cover.

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