[0024] Working principle and use process of the present invention: The molded case controller is mainly used to control the operation of electrical equipment, such as the start and stop and speed regulation of the motor. It can realize the automatic control and management of electrical equipment. Many molded case controllers are programmable, allowing users to set parameters and modify programs according to needs. The internal parts usually contain control circuits, fuses, relays and sensor elements to realize their control functions. They are widely used in industrial automation, mechanical control, and smart home fields. The molded case controller is made of high-strength engineering plastics and has good insulation and corrosion resistance. The use of insulating materials reduces the risk of electric shock. At the same time, many controllers also provide overload and short-circuit protection functions. The controller is wrapped in a plastic case. Wrapping, the poor heat dissipation effect of the plastic shell controller will cause the internal temperature of the device to rise, affecting the performance and response speed of the controller, and may cause inaccurate control signals. The top of the plastic shell controller is not provided with a pressure-resistant structure. After being hit by an external object, it may cause damage to the controller and displacement of internal components. At this time, the plastic shell 2 can wrap the outside of the control device 1, and then fit the bottom of the plastic shell 2 and the top of the pressure-resistant seat 4 against each other, use a screwdriver to thread the four first limit bolts 18 with the corresponding positioning holes 6, and continue to embed the four card blocks 10 into the inside of the two card slots 9, and the two are snap-connected, so that the heat sink 12 is installed on the outer wall of the plastic shell 2, and the heat sink The outer wall of 12 is in contact with the outer wall of the heat conducting plate 3. Through good contact with the heat conducting plate 3, the conducted heat can be effectively dissipated into the surrounding air, thereby reducing the operating temperature of the control device 1. The multiple pressure dividing plates 5 can evenly distribute the weight of the control device 1, thereby reducing the local pressure on the mounting surface. The operator embeds one end of the multiple embedding strips 15 into the interior of the multiple straight blocks 14, and the two are engaged with each other, so that the compression ribs 16 are covered and installed on the top of the plastic shell 2. The compression ribs 16 can reduce the collision force between the outside and the top of the plastic shell 2, thereby protecting the control device 1 from compression. After the compression seat 4 is tightly fitted with the plastic shell 2, the first limiting bolt 18 is used to fix the compression seat 4. The threaded connection of the positioning hole 6 further ensures the firmness of the anti-pressure seat 4 and the plastic shell 2. After the anti-pressure seat 4 and the plastic shell 2 are installed with each other, the bottom surfaces of the two L-shaped plates 19 are respectively abutted against the tops of the two bonding plates 21, and the bottom surfaces of the four triangular plates 20 are respectively in contact with the tops of the bonding plates 21. The triangular plates 20 are arranged in a triangular shape, and the triangle has stability, which also enhances the stability of the plastic shell 2. The anti-pressure seat 4 can be fixed to the mounting surface by utilizing the threaded connection of the four bonding plates 21 and the mounting surface. The ventilation groove 23 increases the air circulation area between the inside of the control device 1 and the outside of the plastic shell 2, and can discharge the hot air in the plastic shell 2 to help reduce the temperature.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
