Description

Technical Field

[0001] The utility model belongs to the technical field of servo motors, and in particular relates to a housing of a servo driver and a servo driver. Background Art

[0002] Servo drives, also known as "servo drives" and "servo amplifiers", are a type of controller used to control servo motors. The servo drive structure includes a front panel, a housing, a heat sink, an LED bracket, and an LED substrate; the heat sink is mounted on the housing, the LED bracket is mounted on the heat sink by screws, and the LED substrate is then screwed on the LED bracket; the front panel is mounted on the housing to form a closed accommodating cavity, so that the LED substrate and the LED bracket are located in the closed accommodating cavity. During assembly, the LED substrate and the front panel do not form a positioning and matching structure, and there are installation errors or design errors in the position of the LED substrate and the front panel, resulting in displacement. The LED substrate is easily squeezed and interfered by the front panel, and collisions are likely to occur, causing the LED lamp on the LED substrate to whiten. In addition, there are many assembly parts, a long construction period, and cumbersome operations. Utility Model Content
