Patent ID: 7766687

Claim:
A connector for connecting a first electrode of a circuit to a first electrical element and for connecting a second electrode of the circuit to a second electrical element, wherein the first electrical element includes a first conductor surrounded by a first isolation layer and the second electrical element includes a second conductor surrounded by a second isolation layer, the second isolation layer being smaller than the first isolation layer, the connector comprising: a first pair of recesses forming a first opening for receiving the first electrical element and a second pair of recesses forming a second opening for receiving the second electrical element, the second opening being smaller than the first opening so that the second opening and the first opening respectively receive first electrical element and the second electrical element in a non-interchangeable way; a first contact extending from a recess of the first pair of recesses into the first opening for penetrating the first isolation layer and contacting the first conductor; and a second contact extending from a recess of the second pair of recesses into the second opening for penetrating the second isolation layer and contacting the second conductor; wherein a length of the second contact is smaller than a length of the first contact.
