Description

Technical Field

[0001] This utility model relates to the field of controller structure technology, and in particular to an anti-interference controller structure. Background Technology

[0002] A temperature controller is an intelligent device that detects ambient temperature using sensors and compares it with a set value, automatically adjusting heating or cooling equipment to maintain a target temperature. It is used in high-end fields such as aerospace, biomedical cultivation, medical devices, and constant-temperature workshops for precision electronic components. In these scenarios where extremely high temperature control accuracy is required, external electromagnetic interference can cause distortion of the temperature controller's detection signal or lag in its adjustment action, thus affecting its ability to stably maintain the target temperature.

[0003] A search revealed that authorization announcement number CN211831703U discloses an anti-interference controller structure, including a shielding cover, a controller body, and a base plate. This invention inserts the side plate at the lower end of the snap-fit ​​cover into the mounting groove, and snaps the front and rear cover plates (passing through the wiring terminals) into the snap-fit ​​cover. The connection principle is simple. The use of a dense copper-aluminum shell material allows the shielding cover and base plate to provide anti-interference for the controller body. The outer periphery is also made of a dense copper-aluminum shell material to prevent external electromagnetic waves from affecting the normal operation of the controller body. Sealing gaskets are provided below the front and rear cover plates to improve the sealing of the shielding cover and prevent the entry of external impurities. An arc surface is provided at the inner corner of the lower end of the side plate, making it easier to insert the side plate into the mounting groove compared to a side plate with a straight corner, facilitating installation. A limit block is provided on the inner side of the upper end of the side plate to limit the insertion depth of the side plate.

[0004] However, existing temperature controllers do not have good anti-interference capabilities, making them susceptible to electromagnetic interference during use. Therefore, there is an urgent need in the market for an anti-interference controller structure to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-interference controller structure to solve the problem mentioned in the background art that the existing temperature controllers do not have a good anti-interference effect, making them susceptible to electromagnetic interference during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-interference controller structure includes a controller body, a mounting end at the front end of the controller body, a front control end mounted on one side of the mounting end, a mounting chamber inside the controller body, limit mounting seats at each of the four corners of the mounting chamber, mounting grooves at both ends of the limit mounting seats, heat dissipation fins mounted at the rear end of the controller body, and a shielding device mounted inside the mounting grooves. The shielding device includes a shielding mesh, limit seats, and a mounting handle. Limit seats are arranged around the shielding mesh, and a mounting handle is provided at one end of each limit seat.

[0008] By adopting the above technical solution, the temperature controller can have excellent anti-interference performance, thus improving its performance.

[0009] Furthermore, a display screen is provided at the front end of the front control terminal, and control buttons are provided at the lower end of the display screen.

[0010] By adopting the above technical solution, the temperature controller can be easily controlled, and the monitored data can be observed through the display screen.

[0011] Furthermore, the front control end and the mounting end are fixedly connected by four fixing screws, one end of which passes through the front control end and extends into the interior of the mounting end.

[0012] By adopting the above technical solution, the front control end and the mounting end can be easily installed and fixed, thus facilitating the installation of the front control end and the mounting end.

[0013] Furthermore, a plurality of heat dissipation fins are provided, and the plurality of heat dissipation fins are distributed sequentially at the rear end of the controller body, with one end of the heat dissipation fin passing through the controller body and extending into the interior of the installation chamber.

[0014] By adopting the above technical solution, the heat dissipation fins can be set so that the heat inside the temperature controller can be conducted from one end of the heat dissipation fins to the other end of the heat dissipation fins and then dissipated to the outside. This can prevent the internal temperature of the temperature controller from being too high, thereby affecting the service life of the temperature controller.

[0015] Furthermore, a plug-in chamber is provided inside the rear end of the controller body, and a plug-in socket is provided inside the plug-in chamber.

[0016] By adopting the above technical solution, the temperature controller can be made more convenient to use, while also providing good protection for the connector.

[0017] Furthermore, the installation handle and the limiting seat are an integral structure, and the shielding mesh and the shielding device are fixedly connected by a slot.

[0018] By adopting the above technical solution, the structure between the installation handle and the limit seat can be made more robust, and the shielding mesh and the shielding device can be connected by a slot, making it easy to disassemble and replace if the shielding mesh is damaged.

[0019] Furthermore, the shielding mesh is woven from a series of tin-plated copper wires in a crisscross pattern.

[0020] By adopting the above technical solution, the shielding effect of the shielding mesh can be improved, thus making the temperature controller less susceptible to electromagnetic interference during use.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The present invention allows one end of the shielding device to be easily inserted into the mounting groove at both ends of the limit mounting seat by means of the installation handle. The installed shielding device enables the temperature controller to perform electromagnetic shielding well, thus improving the anti-interference performance of the temperature controller. The shielding mesh is made of several tin-plated copper wires crisscrossed, which can effectively improve the electromagnetic shielding effect.

[0023] (2) When the components installed inside the installation chamber of this utility model are working, they will generate heat. The heat is conducted through one end of the heat dissipation fins located inside the installation chamber, and the heat is dissipated to the outside from the other end of the heat dissipation fins. This allows the temperature controller to dissipate heat well, thereby avoiding overheating inside the temperature controller and affecting its service life. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please see Figure 1-5 This utility model provides an embodiment of an anti-interference controller structure, comprising a controller body 1, a mounting end 101 at the front end of the controller body 1, a front control end 2 mounted on one side of the mounting end 101, the front control end 2 and the mounting end 101 being fixedly connected by four fixing screws 3, one end of each fixing screw 3 passing through the front control end 2 and extending into the interior of the mounting end 101, a display screen 201 at the front end of the front control end 201, a control button 202 at the lower end of the display screen 201, a mounting chamber 102 inside the controller body 1, a limit mounting seat 103 at each of the four corners of the mounting chamber 102, and mounting grooves 104 at both ends of each limit mounting seat 103, and a plug at the rear end of the controller body 1. The connection chamber 105 has a plug-in socket 4 inside. The rear end of the controller body 1 is equipped with heat dissipation fins 5. The mounting groove 104 is equipped with a shielding device 6. The shielding device 6 includes a shielding mesh 7, a limiting seat 8, and a mounting handle 9. The shielding mesh 7 is surrounded by limiting seats 8, and one end of the limiting seat 8 is equipped with a mounting handle 9. The front control end 2 can be used to easily control the operation of the temperature controller. The limiting mounting seat 103 and the mounting groove 104 can be used to easily limit the installation of the shielding device 6. The shielding device 6 gives the temperature controller a good electromagnetic shielding effect. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working principle and working process of the temperature controller, it will not be described in detail in this patent.

[0032] See Figure 1 , Figure 2 and Figure 3Several heat dissipation fins 5 are provided, and the heat dissipation fins 5 are distributed sequentially at the rear end of the controller body 1. One end of the heat dissipation fin 5 passes through the controller body 1 and extends into the interior of the mounting chamber 102. Since one end of the heat dissipation fin 5 is located inside the mounting chamber 102, the heat generated by the components inside the mounting chamber 102 during operation can be discharged to the outside through heat conduction, thereby avoiding excessive temperature inside the mounting chamber 102, which would affect the service life of the controller.

[0033] See Figure 4 The handle 9 and the limit seat 8 are integrated into one structure. The shielding mesh 7 and the shielding device 6 are fixedly connected by a slot. The shielding mesh 7 is made of several tin-plated copper wires crisscrossed. This setting allows for easy installation between the shielding mesh 7 and the shielding device 6. The shielding mesh 7 improves the anti-interference effect of the controller and prevents external electromagnetic interference from affecting the use of the controller.

[0034] Working principle: During use, the shielding device 6 can be easily inserted into the mounting slots 104 at both ends of the limiting mounting base 103 by using the mounting handle 9. The installed shielding device 6 enables the temperature controller to be well electromagnetically shielded, thus improving the anti-interference ability of the temperature controller. When the components installed inside the mounting chamber 102 are working, they generate heat. The heat is conducted through one end of the heat dissipation fins 5 located inside the mounting chamber 102, and the heat is dissipated to the outside from the other end of the heat dissipation fins 5. This enables the temperature controller to dissipate heat well, thereby avoiding overheating inside the temperature controller and affecting its service life.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
