Abstract

An electronic device includes a fork structure having a pair of arms disposed in spaced relation and defining an open-ended channel therebetween. A surface of channel defines a seat opposite the open end. The channel has a width W 1 at its narrowest section. A rigid wire of an electrical component is disposed in the channel generally adjacent to the seat. The wire has a width W 2 that is greater than the width W 1 so surfaces of the channel at the narrowest section defined by width W 1 interfere with the wire, preventing the wire from moving towards the open end of the channel. The pair of arms are constructed and arranged to be moved toward each other so as to crimp the wire to the fork structure.

First claim

What is claimed is:

1. An electronic device comprising:
a fork structure comprising a pair of arms disposed in spaced relation and defining an open-ended channel therebetween, a surface of channel defines a seat opposite the open end, the channel having a width W 1 at its narrowest section; and
a rigid wire of an electrical component disposed in the channel generally adjacent to the seat, the wire having a width W 2 that is greater than the width W 1 so surfaces of the channel at the narrowest section defined by width W 1 interfere with the wire, preventing the wire from moving towards the open end of the channel;
wherein the pair of arms are constructed and arranged to be moved toward each other so as to crimp the wire to the fork structure, and the cross-section of the wire remains unchanged;
wherein a portion of the channel near the seat has a width W 3 at its largest section that is greater than width W 1 , and greater than a width of any other portion of the channel, and wherein the width W 2 is smaller than the width W 3 ;
wherein the portion of the channel is adjacent to the seat and is configured to correspond in shape with a cross-sectional shape of the wire.

2. The electronic device of claim 1 , wherein the wire extends from a capacitor defining the electrical component.

3. The electronic device of claim 1 , wherein a cross-section of the wire is circular.

4. The electronic device of claim 1 , wherein the cross-sectional shape of the wire is circular.

5. A fork structure for coupling with a rigid wire of an electronic component, the fork structure comprising:
a pair of arms disposed in spaced relation and defining an open-ended channel therebetween, a surface of channel defining a seat opposite the open end, the channel having a width W 1 at its narrowest section, the channel having a portion adjacent to the seat having a width W 3 at its largest section that is greater than width W 1 and greater than a width of any other portion of the channel;
wherein the pair of arms are moved towards each other so as to crimp the wire to the fork structure, such that the cross-section of the wire remains unchanged;
wherein, in combination with the wire, the wire having a width W 2 that is greater than the width W 1 so surfaces of the channel at the narrowest section defined by width W 1 interfere with the wire, preventing the wire from moving towards the open end of the channel;
wherein the portion of the channel adjacent to the seat is configured to correspond in shape with a cross-sectional shape of the wire.

6. The fork structure of claim 5 , wherein the width W 2 is smaller than the width W 3 .

7. A method of mechanically and electrically connecting a rigid wire of an electrical component to a fork structure, the method comprising the steps of:
providing the fork structure having a distal end defined by pair of arms disposed in spaced relation defining an open-ended channel therebetween, a surface of channel defining a seat opposite the open end, the channel having a width W 1 at its narrowest section,
providing the electrical component having the rigid wire extending therefrom, the wire having a width W 2 that is greater than the width W 1 , the channel having a portion adjacent to the seat that corresponds in shape with a cross-sectional shape of the wire,
moving an end of the wire into the open end of the channel past the narrowest section thereof and into the portion so that the wire is generally adjacent to the seat, and
moving the arms towards each other to close the open end of the channel and thus crimp the wire to the fork structure while surfaces of the channel at the narrowest section thereof interfere with the wire to prevent the wire from moving towards the distal end the channel, and with the portion of the channel limiting deformation of the wire during crimping, and the cross-section of the wire remains unchanged after crimping.

8. The method of claim 7 , further comprising welding tips of the arms together to thereby electrically and mechanically connect the wire to the fork structure.

9. The method of claim 7 , wherein the fork structure is provided such that the portion of the channel adjacent to the seat has a width W 3 at its largest section that is greater than width W 1 and greater than a width of any other portion of the channel, and wherein the width W 2 is smaller than the width W 3 .

10. The method of claim 7 , wherein the wire extends from a capacitor defining the electrical component.

11. The method of claim 7 , wherein a cross-section of the wire is circular.
