Electrical connector

1. An electrical connector comprising

a dielectric housing; and

a plurality of arrays of terminals disposed in respective portions of the dielectric housing, wherein at least two of the arrays of terminals have different respective pitches;

wherein at least one of the respective portions of the dielectric housing is partially removed such that a value of the dielectric constant between terminals of the array of terminals in said portion of the dielectric housing is controlled, wherein the terminals disposed in said portion of the dielectric housing are partially exposed; and

wherein an opening is formed completely through a wall of the dielectric housing in said portion, and the terminals in said portion extend across the opening from a bottom of the opening to a top of the opening.

2. The connector as claimed in claim 1 , wherein the portion of the dielectric housing in which the array having a smaller pitch is disposed is partially removed.

3. The connector as claimed in claim 1 , wherein the arrays of terminals comprise one or more power terminal arrays and one or more signal terminal arrays.

4. The connector as claimed in claim 3 , wherein at least the portion of the dielectric housing in which one signal terminal array is disposed is partially removed.

5. The connector as claimed in claim 1 , wherein the at least one of the respective portions of the dielectric housing which is partially removed comprises a protruded housing section of the dielectric housing.

6. The connector as claimed in claim 1 , wherein the connector comprises a Serial Attached SCSI Receptacle.

7. The connector as claimed in claim 1 , wherein the terminals comprise one or more of a group comprising through-hole, surface mount, press fit, and compression fit terminals.

8. The connector as claimed in claim 1 , wherein the value of the dielectric constant between terminals of the array of terminals in said portion of the dielectric housing is reduced.

9. An electrical connector comprising:

a dielectric housing; and

a plurality of arrays of terminals disposed in respective portions of the dielectric housing,

wherein at least two of the arrays of terminals have different respective pitches;

wherein at least one of the respective portions of the dielectric housing is partially removed such that a value of the dielectric constant between terminals of the array of terminals in said portion of the dielectric housing is controlled; and

wherein the at least one of the respective portions of the dielectric housing which is partially removed comprises a protruded housing section of the dielectric housing.

10. An electrical connector comprising

a dielectric housing having a plug receiving slot between opposite walls of the dielectric housing;

a first array of terminals disposed in a first portion of the dielectric housing; and

a second array of terminals disposed in a second portion of the dielectric housing, wherein the terminals in the first array have a different pitch relative to the terminals in the second array,

wherein the dielectric housing comprises at least one slot extending completely through a first one of the walls of the dielectric housing at the second portion between the plug receiving slot and an exterior of the first wall, wherein the terminals in second array extend across the at least one slot, and wherein the terminals in second array are exposed at opposite sides of the first wall at the at least one slot.

11. An electrical connector as in claim 10 wherein the at least one slot comprises an opening completely through the first wall of the dielectric housing at the second portion, wherein the terminals in second array extend across the opening, wherein the opening provides an air gap directly between the terminals of the second array at the opening, and wherein the terminals are exposed at opposite sides at the first wall at the opening.
