One side 142 is formed with a concave shape 143, and the corresponding cable electrical connector 200 has a protruding portion 208. After the cable electrical connector 200 is inserted into the mating electrical connector 120, the protruding portion 208 is received in the concave shape 143. The width of the concave shape 143 is the same as the width of the seat body 140 such that the first side 142 of the socket forms a step relative to the second side 144. The first side 142 is mounted with a first row of terminals 162 (first row of terminals) arranged in the width direction, and the second side 144 is mounted with a second row of terminals 164 (second row of terminals) and a third row arranged in the width direction. The terminal 168 (third terminal) and the second row of terminals 164 are spaced apart from the third row of terminals 168 in the front-rear direction. Each row of terminals is configured to be in conductive engagement with each of the rows of conductive sheets. The rows of terminals are provided with connecting portions 166 at the same horizontal plane, so that the rows of terminals can be mounted on the same side of an external device circuit board (not shown). The first row of terminals 162 and the second row of terminals 164 conform to the SFP+ standard interface.

Each of the first row of terminals 162 and one of the second row of terminals 164 are integrally formed with an insulating plastic 172 and fixed to the base 140 by the insulating plastics 172.

In the manufacturing process, the first row of terminals 162 and the second row of terminals 164 in the same insulating plastic 172 can be die cut from the same metal strip and are in two parallel planes having the aforementioned offset distance. Because of the high-density electrical connector, each of the insulating plastics 172 covers the first row of terminals 162 and the second row of terminals 164, and the thickness of the second row of terminals 164 is very thin, and it is easy to form a phenomenon of insufficient saturation, in order to increase the coverage of the first row of terminals 162 and the second. The thickness of the terminal 164 at a specific position is designed to design the insulating plastic 172 as a step having a certain offset distance, thereby facilitating the overmolding of the insulating plastic 172. Each of the terminals of the third row of terminals 168 is integrally formed on an insulating plastic 178 and fixed to the base 140 by an insulating plastic 178. Further, the first row of terminals 162, the second row of terminals 164, and the third row of terminals 168 do not overlap in the width direction, so that the arrangement density in the terminal width direction is large.
