## Abstract

An electrical connector includes an insulating housing and a plurality of contacts retained on a mating portion of the housing. The mating portion has a mating port with a geometric centre. The contacts are divided into an upper array and a lower array. Each array includes several first contacts and at least one pair of second contacts located on two sides of the first contacts, the first contacts of the upper array are centrally symmetric to the first contacts of the lower array relative to the geometric centre of the mating port. The new type of contacts arrangement can improve the quality of the signal transmission.

## Claims

### Claim 1

An electrical connector, comprising:
an insulating housing including a mating portion with a mating port, said mating port having a geometric centre;
a plurality of contacts retained on said mating portion and divided into an upper array and a lower array;
wherein each array includes several first contacts and at least one pair of second contacts located on two sides of said first contacts, said first contacts of the upper array are centrally symmetric to the first contacts of the lower array relative to said geometric centre of the mating port;
wherein said first contacts are signal contacts, said second contacts are power contacts; and
wherein the first contacts of each array are divided into two groups which includes a first group far away from said geometric centre and a second group closer to the geometric centre.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein the pitch between two adjacent first contacts in said first group is smaller than the pitch between two adjacent first contacts in second group.

### Claim 3 (depends on 2)

The electrical connector according to claim 2, wherein said first group includes at least two first contacts, said second group includes at least three first contacts.

### Claim 4 (depends on 3)

The electrical connector according to claim 3, wherein said geometric centre is a crossover point of a horizontal centre line and a vertical centre line of the mating port, the second contacts in said upper array are symmetric with the second contacts in said lower array along said horizontal centre line.

### Claim 5 (depends on 1)

The electrical connector according to claim 1, wherein said electrical connector further includes a shell covering on said insulating housing, said shell has a main portion and a retaining portion extending rearward from said main portion, the retaining portion includes a pair of retaining plates respectively extending from an upper side and a lower side of said main portion, and a pair of locking arms extending from a right side and a left side of said main portion.

### Claim 6 (depends on 5)

The electrical connector according to claim 5, wherein said insulating housing includes a base portion, said base portion has a pair of flange portions and a connecting beam connecting with said flange portions, said connecting beam has a top surface and a front surface, the top surface defines a concave portion, the retaining plate engages with said concave portion of said connecting beam.

### Claim 7 (depends on 6)

The electrical connector according to claim 6, wherein said retaining plate includes at least one protruding which engages into said concave portion, said protruding extends downwardly from a bottom surface of the retaining plate.

### Claim 8 (depends on 7)

The electrical connector according to claim 7, wherein said retaining plate includes a slanted portion and a horizontal portion, said protruding is formed on said horizontal portion, and the slanted portion connects with the main portion.

### Claim 9 (depends on 7)

The electrical connector according to claim 7, wherein said locking arm extends horizontally and has a hooked tail.

### Claim 10 (depends on 9)

The electrical connector according to claim 9, wherein an inserting slot is formed between said flange portion and said mating portion for receiving said locking arm.

### Claim 11 (depends on 10)

The electrical connector according to claim 10, wherein said top surface of the connecting beam is lower than a top surface of the flange portion.
