Patent ID: 7891984

Claim:
An electrical connector, comprising: at least one first insulating substrate having a plurality of first tongues, wherein one end of the first tongue connects to the first insulating substrate, and a first height difference is defined between the other end of the first tongue and the upper surface of the first insulating substrate, wherein a through-hole is formed on the first insulating substrate at each location corresponding to each first tongue; at least one second insulating substrate having a plurality of second tongues, wherein each second tongue passes through the through-hole of the first insulating substrate, and connects to the second insulating substrate at one end, wherein a second height difference is defined between the other end of the second tongue and the upper surface of the first insulating substrate; and a plurality of contacts adhered between the first tongues and the second tongues, wherein the contacts pass through the through-holes of the first insulating substrate, wherein a third height difference is defined between the upper-most portion of the contact and the first insulating substrate, and wherein the third height difference is larger than the first height difference and the second height difference; wherein there is a hole on the second insulating substrate at each location corresponding to each contact for exposing the contact from the second insulating substrate.
