Electrical connector

An electrical connector capable of being detachably connected to another electrical connector, comprising:

• a base;
• and
• a fixing assembly comprising:
• a shaft slidably connected to the base and able to slide toward a first direction along the base;
• at least one positioning post slidably connected to the base and able to slide toward a second direction along the base, the second direction being substantially perpendicular to the first direction, an engaging portion protruding from one end of each of the at least one positioning post;
• and
• at least one connecting bar, two opposite ends of each of the at least one connecting bar being rotatably connected to the shaft and one of the at least one positioning post, respectively;
• wherein the sliding of the shaft toward the first direction causes the at least one positioning post to slide toward the second direction, and when the shaft slides toward the first direction from a first position to a second position, the at least one engaging portion engages the another electrical connector.
