Abstract: A latch-type stackable connector includes a base seat having an insulating seat. Multiple terminals are side by side inlaid in the insulating seat. Multiple fixing latch pieces are respectively inserted in two sides of the insulating seat. Each fixing latch piece having a first end extending to a bottom of the insulating seat to be soldered on a circuit board. A connector having an insulating bed. Multiple terminals are side by side inlaid in the insulating bed. Latching pieces are respectively inserted in two sides of the insulating bed. Each latching piece has a first end protruding from a bottom of the insulating bed to be latched with a second end of the fixing latch piece. A second end of the latching piece is correspondingly tightly latchable with the first end of the latching piece of another connector.
