[0040] As Figures 1 to 6 shown, a docking structure of an electrical connector provided in this embodiment includes a power connection portion and a signal connection portion extending forward from the electrical connector housing 1. The portion of the power connection portion extending out of the electrical connector housing 1 is the first docking end 2, the docking length of the first docking end 2 is D, D = 9.50 mm, the portion of the signal connection portion extending out of the electrical connector housing 1 is the second docking end 3, the docking length of the second docking end 3 is d, d = 6.35 mm, and D > d, so that the first docking end is electrically connected earlier than the second docking end during docking. By adopting the method that the power connection portion and the signal connection portion are exposed to form the first docking end 2 and the second docking end 3, and the docking length of the first docking end 2 is greater than the docking length of the second docking end 3, and guiding through the power connection portion to ensure the insertion of the signal connection portion, using the power connection portion as the guiding structure of the signal connection portion, there is no need to add a docking guiding structure to the electrical connector housing 1, reducing the occupied space of the electrical connector.

[0041] In this embodiment, D:d = 1.496:1. By setting the ratio of the docking length of the first docking end to the docking length of the second docking end, a good docking guiding effect is ensured.

[0042] The first butt joint end 2 of this embodiment has a first guide portion 24. The guide depth of the first guide portion 24 is H, H:D=1:9.50. The first guide portion 24 is used for guidance during butt joint, thereby further improving the butt joint guiding function of the first butt joint end and improving the butt joint efficiency. The ratio setting of the guide depth of the first guide portion and the butt joint length of the first butt joint end ensures a good butt joint guiding effect.

The second guide portion 31 provides guidance during butt joint, further improving the butt joint guiding function of the second butt joint end and improving the butt joint efficiency. The ratio setting of the guide depth of the second guide portion and the butt joint length of the second butt joint end ensures a good butt joint guiding effect.

[0044] The first butt joint end 2 of this embodiment includes an insulator 21 and a conductive portion 22. The insulator 21 covers the conductive portion 22, and the conductive portion 22 has a contact surface 23 exposed to the insulator 21. The first butt joint end 2 adopts an injection molding design, and the connection is stable. In other embodiments, the first butt joint end 2 can also be a PCB board.

[0045] There are two first butt joint ends 2, which are respectively arranged at diagonal positions of the electrical connector housing 1. The first butt joint ends 2 arranged diagonally make the guidance more stable and improve the butt joint efficiency.

[0046] Among them, there are four second docking terminals 3, which are respectively arranged at the upper part, the middle part, and the lower part of the electrical connector housing 1. The second docking terminal 3 at the upper part is arranged opposite to the first docking terminal 2 at the upper part, the second docking terminal 3 at the lower part is arranged opposite to the first docking terminal 2 at the lower part, and there are two second docking terminals 3 at the middle part, which are arranged opposite to each other. By arranging the second docking terminals 3 opposite to the first docking terminals 2 horizontally and arranging the second docking terminals 3 in layers, better space utilization is achieved, which greatly reduces the occupied space of the electrical connector.

[0047] The second butt joint ends 3 at the upper and lower parts have 74 pins 4, each second butt joint end 3 at the middle part has 50 pins 4, and the vertical distance between the two second butt joint ends 3 at the middle part is 1.82 mm. Different pins 4 can be arranged to meet different butt joint requirements.

[0048] Among them, the vertical distance between the second docking end 3 located at the upper part and the first docking end 2 located at the upper part, and the vertical distance between the second docking end 3 located at the lower part and the first docking end 2 located at the lower part are both 2.15 mm. The vertical distance between the second docking end 3 located at the upper part and the second docking end 3 located at the middle part, and the vertical distance between the second docking end 3 located at the lower part and the second docking end 3 located at the middle part are both 6.06 mm. Through the design requirements for the distance, the volume of the electrical connector housing 1 is minimized to the greatest extent.
