Embodiment Construction
[0010] The present invention will be further explained below in conjunction with accompanying drawing.
[0011] like figure 1 shown. The shielding box adopts a semi-box-shaped design of the shielding box body, which is composed of four sides and a bottom surface. The shape of the upper edge of the box body matches the upper cover of the motor controller to form the upper cover of the box body, and then forms a complete box body. Realize signal shielding and make the control panel work stably and reliably. There are six box body fixing holes 1 at the bottom of the box body, which are formed by processing threads in the center of the cylindrical boss, and are used to fix the shielding box body. Four control board fixing holes 3 are distributed at the bottom of the box body, and are processed by the center of the cylindrical boss The thread is formed to fix the control board in the shielding box to ensure the stable position of the control board. At the bottom of the box body,...

The invention discloses a motor controller control panel shielding structure, and belongs to the technical field of a motor controller, mainly for solving the problem of signal interference exerted by external factors including magnetic fields and the like on a controller control panel. The motor controller control panel shielding structure is mainly characterized by comprising a shielding box body and a motor controller upper cover; and the shielding box body is of a half-box type structure, and the shape of the upper edge of the box body and the motor controller upper cover cooperate and are closely combined to form enclosure, such that signal shielding is realized, and the control panel works stably and reliably; the bottom of the shielding box body is provided with box body fixation holes, control panel fixation holes and a connection driving opening such that the connection is simple and reliable; and the shielding box body is internally provided with sensor signal line output grooves. The motor controller control panel shielding structure has the advantages of simple structure, good shielding effect, convenient processing, wide application scope and high practical value, thereby being mainly applied to shielding of the control panel in the motor controller.
Description
technical field [0001] The invention belongs to the technical field of motor controllers, and in particular relates to a control board shielding structure used in a motor controller. Background technique [0002] With the rapid acceleration of the industrialization process, especially the widespread application of motors, in terms of power, the requirements for all aspects of the motor are getting higher and higher, and the essence is to put forward higher requirements for the performance of the motor controller. While considering the influence of the external environment on the hardware of the motor controller, the influence of the electromagnetic field in the external environment and the signal of the controller's own circuit on the control board cannot be ignored. In the existing controllers, jumpers are generally used, which not only fails to achieve a good shielding effect, but also causes serious attenuation of the transmitted signal in the controller and complicates t...
