A connector assembly comprises a first connector, a second connector, at least one outer sliding element, at least one inner sliding element, a first shaft and a second shaft. The second connector is connected with the first connector by a signal cable, and the inner sliding element is relatively slid and rotated with the outer sliding element; the first shaft is rotatably and pivotally engaged with the first connector and the second shaft is rotatably and pivotally engaged with the second connector, and outer sliding element and the inner sliding element are connected between the first shaft and the second shaft. Consequently, the multi-turning connecting head has a multi-direction rotational function and a different-length adjustable function.
