Card-inserting type connector

The invention discloses a card-inserting type connector. The card-inserting type connector comprises a shell, at least two power supply terminals, a signal terminal mounting part, and a pair of terminal groups, wherein fixed terminals which are connected to a first end part and a second end part are detachably inserted into clamping grooves which are formed in the first end part and the second end part; the power supply terminals which are clamped in the power supply terminal mounting part are detachably inserted in mounting grooves which are formed in the power supply terminal mounting part; two rows of separated terminal grooves are formed in the interior of the signal terminal mounting part; the terminal grooves comprise multiple terminal inserting grooves and multiple separating walls which are positioned among the terminal inserting grooves for separating the terminal inserting grooves mutually; a strip-shaped long groove is formed in the bottom of the signal terminal mounting part between the two terminal groups; conductive plastic is assembled in the strip-shaped long groove; the pair of terminal groups is equipped with multiple signal terminals and grounding terminals; each signal terminal and each grounding terminal are both detachably inserted into one corresponding terminal inserting groove; and all the grounding terminals are electrically connected through the conductive plastics.
