[0031] The locking bracket is fixed to the side of the lower box body and is used for installation and connection with the cabinet body.

[0032] From the above description, it can be seen that the beneficial effects of the utility model are: by adding a shielding installation box assembled with an upper cover and a lower box body, the control board body can be installed in the shielding installation box, and then installed in the required cabinet through a locking bracket to shield the external electromagnetic interference to the control board; at the same time, a through hole is opened on the side of the upper cover of the shielding installation box to install a debugging lead-out interface, and a wiring harness is used to lead out the debugging interface on the control board body and connect it to the debugging lead-out interface, which is convenient for plugging and unplugging the interface for debugging wiring.

[0033] Furthermore, the upper cover and the lower box body are detachably assembled by screws;

[0034] The screw locking parts between the upper cover and the lower box body are coated with conductive paint;

[0035] The position where the locking bracket is used for installation and connection with the cabinet is also coated with the conductive paint.

[0036] From the above description, it can be seen that the upper cover and the lower box body are connected to each other through the conductive paint on the lock contact surface, and then the lock bracket welded on the lower box body and the shielding installation box are installed in the cabinet and grounded at the contact position with the cabinet to further effectively achieve the purpose of electromagnetic shielding and avoid the control board body from being affected by electromagnetic interference generated by external devices.

[0037] Furthermore, the locking bracket is L-shaped, and one side of the L-shape of the locking bracket is welded to the side surface of the lower box body, and the other side of the L-shape is flush with the bottom surface of the lower box body;

[0038] The conductive paint is arranged on one side of the L-shape where the locking bracket is flush with the bottom surface of the lower box body.

[0039] From the above description, it can be seen that the locking bracket adopts an L-shaped structure, one side of which can be fitted with the side of the lower box body, and the other side is flush with the place where the cabinet is installed, so that the shielding installation box can be stably and firmly installed in the cabinet, avoiding shaking and collision that may cause damage to the control panel body in the box.

[0040] Furthermore, the locking brackets are symmetrically arranged on the side of the lower box body, and there is at least a pair of locking brackets.

[0041] It can be seen from the above description that the locking brackets are arranged opposite to each other and are at least a pair, which can further improve the installation stability and firmness of the shielding installation box.

[0042] Furthermore, the upper cover and the lower box body are both shells made of carbon steel material.

[0043] It can be seen from the above description that the upper cover and the lower box body made of carbon steel material can further ensure the strength of the shielding installation box and further play a role in protecting the control board body.

[0044] Furthermore, the lower box body is provided with control board mounting studs, and the control board body is fixed to the lower box body by means of screws being detachably locked to the control board mounting studs.

[0045] As can be seen from the above description, the control board body is then screwed to the control board mounting studs provided in the lower box body, so that the control board body is fixed in the shielding mounting box and will not shake or collide to cause damage.

[0046] Furthermore, a side surface of the shell structure formed by assembling the upper cover and the lower box body and a position corresponding to the external plug-in connector on the control board body are provided with an avoidance hole.

[0047] From the above description, it can be seen that there are some connectors for external connection on the control board body, and the plug-in and unplugging frequency of these connectors is relatively high. In order to facilitate the use of these external connectors, avoidance holes are opened at the corresponding positions of the shielding installation box to avoid the external connectors.
