Abstract

An electrical connector (1) comprises an insulative housing (2) defining a number of passageways (220), and a number of contacts (3) received in the passageways. Each contact has different widths along longitudinal axis thereof for adjusting its own impedance. The housing includes a number of inwardly extending channels (224) communicating with corresponding passageways, a number of slots (222) between adjacent passageways and a number of cavities (206) each communicating with a corresponding passageway to respectively define a first clearance (226), a second clearance (208) and a third clearance (228) between each contact and the housing for adjusting the impedance of the contact.

Claims

1. An electrical connector comprising:

an insulative housing defining a plurality of passageways; and

a plurality of contacts received in the passageways of the housing, each contact having different widths along the longitudinal axis thereof;

wherein the housing includes a plurality of channels communicating with the corresponding passageways, a plurality of slots between adjacent passageways and a plurality of cavities each communicating with a corresponding passageway to respectively define a first clearance, a second clearance and a third clearance between each contact and the housing, the second and third clearances each being filled with air;

wherein the insulative housing comprises a base section and a mating section projection from the base section, and wherein the passageways are arranged in a single row and extend from the mating section to a bottom surface of the base section, the slots being defined in the mating section;

wherein the contact has a narrow segment, and the first clearance is provided by a corresponding passageway on opposite sides of each narrow segment;

wherein the cavities are defined in the base section in a direction parallel to the mating section, and the second clearance is provided by a corresponding cavity between the insulative housing and the contact;

wherein the channel extends from the mating section to the bottom surface of the base section and is recessed into the housing, and the third clearance is provided by a corresponding channel between the insulative housing and the contact;

wherein the contacts include a plurality of signal and ground contacts, an upper portion of each ground contact being nearer to a top end of the mating section than an upper portion of each signal contact.
