[0032] Further, the cross-section of the snap block 910 is in the shape of a right triangle, with its bottom side provided on the outer side walls of the pin housing 110 and the hole housing 210, its right angle side close to the insertion surface 300, and its hypotenuse away from the insertion surface 300; when the housing and the cover plate are snapped together, it is convenient for the snap block 910 to lift the snap arm 810 through the hypotenuse surface and then slide into the notch 811 of the snap arm 810. At the same time, the right angle side surface of the snap block 910 abuts against the inner side wall of the notch 811 close to the insertion surface 300, preventing the snap block 910 from accidentally slipping out of the notch 811 of the snap arm 810.

[0033] Furthermore, the diameter of the current pin 140 is greater than that of the signal pin 130. The signal pins 130 are arranged in an array in the middle of the plugging surface 300, and the current pins 140 are arranged on both sides of the signal pin 130 array.

The pin socket includes a pin housing, a pin cover plate, multiple groups of signal pins and multiple groups of current pins. The jack socket includes a hole housing, a hole cover plate, a steel sleeve, multiple groups of signal jack components and multiple groups of current jack components. Positioning holes corresponding to each group of pins and jacks are provided on both the pin cover plate and the hole cover plate. During installation, by fastening the pin housing and the pin cover plate, as well as fastening the hole housing and the hole cover plate, each group of pins and jacks are fixed in the positioning holes, reducing the procedures for installing the pin socket and the jack socket and improving production efficiency; a steel sleeve is sleeved on the outer peripheral side of the signal jack component, which can improve the shielding effect of the electrical signal at the connector position and improve the reliability of the connector.
