The at least two rows of contacts extend in a first direction. A plurality of first contacts of a first row of the at least two rows of contacts corresponds to a plurality of second contacts of a second row of the at least two rows of contacts. A pair of corresponding contacts in the first row and second row is staggered in the first direction by a predetermined distance set to be 1.20-1.80 times a contact pitch between a pair of adjacent contacts in each of the first row and second row. ## Claims ### Claim 1 A connector, comprising: an insulation body; and at least two rows of contacts disposed in the insulation body and extending in a first direction, a plurality of first contacts of a first row of the at least two rows of contacts corresponding to a plurality of second contacts of a second row of the at least two rows of contacts, a pair of corresponding contacts in the first row and second row are staggered in the first direction by a predetermined distance set to be 1.20-1.80 times a contact pitch between a pair of adjacent contacts in each of the first row and second row, and in each row of contacts any two adjacent pairs of the same type of contacts are separated from a pair of a second type of contacts by a ground in the same row as the pairs of adjacent contacts. ### Claim 2 (depends on 1) The connector of claim 1, wherein the predetermined distance is 1.35-1.65 times the contact pitch. ### Claim 3 (depends on 1) The connector of claim 1, wherein the predetermined distance is 1.5 times the contact pitch. ### Claim 4 (depends on 1) The connector of claim 1, wherein the predetermined distance is set such that a resonance between the first row and the second row is zero. ### Claim 5 (depends on 1) The connector of claim 1, wherein the first row and the second row each have at least one pair of high-speed differential signal contacts. ### Claim 6 (depends on 5) The connector of claim 5, wherein the first row and the second row each have a ground contact disposed on each side of each pair of high-speed differential signal contacts. ### Claim 7 (depends on 6) The connector of claim 6, wherein the first row and the second row each have at least one pair of low-speed differential signal contacts. ### Claim 8 (depends on 7) The connector of claim 7, wherein the first row and the second row each have a ground contact disposed on each side of each pair of low-speed differential signal contacts. ### Claim 9 (depends on 1) The connector of claim 1, wherein the first contacts and second contacts each have a soldering portion at a first end, a contact portion at an opposite second end, and a connecting portion connecting the soldering portion and the contact portion. ### Claim 10 (depends on 9) The connector of claim 9, wherein the soldering portions, the connecting portions, and the contact portions of any pair of corresponding contacts in the first row and second row are staggered in the first direction by the predetermined distance. ### Claim 11 (depends on 9) The connector of claim 9, wherein the soldering portions of any pair of corresponding contacts in the first row and second row are staggered in the first direction by the predetermined distance and the contact portions of any pair of corresponding contacts in the first row and second row are not staggered in the first direction. ### Claim 12 (depends on 9) The connector of claim 9, wherein the contact portions of any pair of corresponding contacts in the first row and second row are staggered in the first direction by the predetermined distance and the soldering portions of any pair of corresponding contacts in the first row and second row are not staggered in the first direction. ### Claim 13 (depends on 1) The connector of claim 1, wherein all portions of any pair of corresponding contacts in the first row and second row are staggered in the first direction by the predetermined distance. ### Claim 14 (depends on 1) The connector of claim 1, wherein a first portion of any pair of corresponding contacts in the first row and second row is staggered in the first direction by the predetermined distance and a second portion of the pair of corresponding contacts in the first row and second row is not staggered in the first direction by the predetermined distance or is staggered in the first direction by a distance less than the predetermined distance. ### Claim 15 (depends on 14) The connector of claim 14, wherein the first contacts and second contacts each have a soldering portion adapted to be soldered to a circuit board, a contact portion electrically contacting a mating connector, and a connecting portion connecting the soldering portion and the contact portion. ### Claim 16 (depends on 15) The connector of claim 15, wherein the connecting portion has a first connecting portion substantially perpendicular to a surface of the circuit board and a second connecting portion substantially parallel to the surface of the circuit board. ### Claim 17 (depends on 16) The connector of claim 16, wherein the first connecting portions and the soldering portions of any pair of corresponding contacts in the first row and second row are staggered in the first direction by the predetermined distance. ### Claim 18 (depends on 17) The connector of claim 17, wherein the second connecting portions and the contact portions of any pair of corresponding contacts in the first row and second row are not staggered or are staggered by a distance less than the predetermined distance in the first direction.
