1. A lamp controller, comprising a circuit board (1), a main housing (2), a plug-in socket (6) and an output plug-in component (7), wherein the main housing (2) consists of an upper housing (10) and a lower housing (11), the upper housing (10) and/or the lower housing (11) are provided with cavities (12), after the upper housing (10) and the lower housing (11) are combined, an accommodating cavity for assembling the circuit board (1) is formed between the upper housing (10) and the lower housing (11), the axial direction of the plug-in socket (6) is not parallel to the longitudinal direction of the main housing (2), and the output plug-in component (7) is fixed with the plug-in socket (6), wherein the controller further comprises an output connecting terminal (5), the output connecting terminal (5) is fixed on the circuit board (1), the circuit board (1) is provided with a yielding opening (1a), a part of the output plug-in component (7) is located in the cavity (12) of the upper housing (10) or the lower housing (11), after the plug-in socket (6) is fixed with the main housing (2), when the circuit board (1) is assembled into the cavity (12) of the upper housing (10) or the lower housing (11), the output connecting terminal (5) is connected with the output plug-in component (7) again after the end of the output plug-in component (7) passes through the yielding opening (1a) on the circuit board (1);
the length of the yielding opening (1a) is greater than or equal to the length of the part of the output plug-in component (7) located in the cavity (12), and one end of the output plug-in component (7) passes through the yielding opening (1a) during the longitudinal movement of the circuit board (1) along the upper housing (10) or the lower housing (11); and
alternatively, the length of the yielding opening (1a) is less than or equal to the length of the part of the output plug-in component (7) located in the cavity (12), so that the circuit board (1) is inclined to the upper housing (10) or the lower housing (11) and moves to connect the output connecting terminal (5) with the output plug-in component (7).
