Plug-in connector

A plug-in connector comprising:

• a housing having, from an end on one side to an end on other side, a first end part, a power supply terminal mounting part, a connecting part, a signal terminal mounting part, and a second end part that are connected as a whole, wherein a fixed terminal connected to the first end part and the second end part is detachably inserted into a clamping groove provided on the first terminal part and the second terminal part;
• at least two power supply terminals, wherein the power supply terminals clamped on a power supply terminal mounting part are detachably inserted inside a mounting groove provided on the power supply terminal mount;
• a signal terminal mounting part, provided with two separated rows of terminal grooves therein, wherein the terminal groove includes a plurality of terminal inserting grooves and a plurality of spacing walls that are positioned between the terminal inserting grooves to separate the terminal inserting grooves from each other, and wherein a bottom of the signal terminal mounting part between two terminal groups is provided with a strip-type groove in which conductive plastic is mounted;
• and
• a pair of terminal groups, having a plurality of signal terminals and ground terminals, wherein each of the signal terminals and each of the ground terminals are detachably plugged into a terminal inserting groove, and wherein all of the ground terminals are electrically connected through the conductive plastic.
