Connector mechanism capable of adjusting a height of an opening thereof

A connector mechanism comprising:

• a base;
• a casing for covering the base, an opening being formed on a side of the base and the casing;
• a circuit terminal installed in the base;
• a sliding socket connected to the base in a slidable manner along the base and disposed on a side of the circuit terminal, at least one hole being formed on the sliding socket;
• a contacting terminal installed on the sliding socket, the contacting terminal passing through the hole for contacting with the circuit terminal;
• a sliding cover pivoted to the sliding socket;
• and
• at least one U-shaped resilient component, one end of the resilient component being connected to the sliding socket, the other end of the resilient component being connected to the sliding cover, and the resilient component driving the sliding cover to separate from the sliding socket when the sliding socket slides outwardly from the casing relative to the base where the casing does not constrain the sliding cover so as to generate a distance between the sliding cover and the sliding socket greater than a height of the opening.
