Abstract
A strain-resistant electrical connection and a method of making the same is provided. An antenna (36, 38) or other conductive lead is connected to a circuit (32) in a manner that makes the connection more resistant to mechanical stresses such as movement or rotation of the antenna (36, 38) or conductive lead relative to the circuit (32). The antenna (36, 38) or conductive lead is at least partially coiled to provide additional ability to withstand mechanical stresses. The antenna (36, 38) or conductive lead may be encase along with is connected circuit in an elastomeric material.
Claims21
A method of creating a fatigue-resistant connection, comprising:
- providing an electrical conductor having first and second coiled portions;
- providing an electrical circuit component, said electrical circuit component having at least one electrical lead extending there from;
- providing a printed circuit board;
- mounting the electrical component to the printed circuit board;
- securing a portion of the first coiled portion of the electrical conductor to the at least one electrical lead of the electrical circuit component and the printed circuit board;
- and
- securing a portion of the electrical conductor between the first and second coiled portions to the printed circuit board.
An RFID transponder, comprising:
- a substrate;
- an RFID element mounted to said substrate, said RFID element having at least one antenna connection terminal;
- and
- an antenna element, said antenna element comprising an electrical conductor having first and second coil pitch portions, said first coil pitch portion coupled to said at least one antenna connection terminal;
- wherein said substrate includes a first solder pad and said first coil pitch portion of said antenna element and said antenna connection terminal of said RFID element are soldered to said first solder pad;
- and
- wherein said substrate includes a second solder pad and a portion of the antenna element between said first and second coil pitch portions is soldered to said second solder pad.
A tire mounted fatigue-resistant electrical connection, comprising:
- a circuit board;
- an electrical circuit component, said electrical circuit component having at least one electrical lead extending there from;
- and
- an electrical conductor having first and second coiled portions;
- wherein the electrical component is mounted to the circuit board and a portion of the first coiled portion of the electrical conductor is secured to the at least one electrical lead of the electrical circuit component and the circuit board;
- and
- wherein a portion of the electrical conductor between the first and second coiled portions is secured to the circuit board.
