Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and in particular to a temperature controller. Background Technology

[0002] A thermostat is a series of automatic control components that, based on changes in the ambient temperature, undergo physical deformation within the switch to produce certain special effects, resulting in either a conduction or a disconnection action. It is also called a temperature control switch, temperature protector, or temperature controller, or simply a thermostat. Alternatively, the temperature protector transmits the temperature to the temperature controller, which then issues a switching command to control the operation of the equipment to achieve the desired temperature and energy-saving effect.

[0003] Thermostats are electrical components installed in equipment such as heaters. To improve assembly efficiency and allow workers to remove thermostats more quickly, they are usually not packaged individually. Thermostats are often stored and transported in clusters. In such environments, thermostats are prone to collisions. When these collisions occur, the temperature-sensing components of the thermostats may be physically deformed, leading to damage and failure of the thermostats, which in turn affects the product yield.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a temperature controller that, by setting up an installation cavity, reduces the chance of physical deformation of the temperature sensing component due to contact and collision, thereby improving the product yield.

[0006] A temperature controller designed for this purpose includes a mounting plate and a temperature sensing component fixedly connected to one side of the front of the mounting plate. The mounting plate has a receiving portion on the outer side corresponding to the temperature sensing component, the receiving portion protruding towards the front of the mounting plate, the inner side of the receiving portion is hollow and forms a mounting cavity for accommodating the temperature sensing component, the left and right sides of the receiving portion have openings for the temperature sensing component to enter or leave the mounting cavity, and the left and right sides of the temperature sensing component are respectively provided with terminal connection portions, the terminal connection portions extending outward from the openings, and the terminal connection portions are fixedly connected to the front of the mounting plate.

[0007] The mounting plate has an opening on one side of the back corresponding to the mounting cavity, and the temperature sensing component is spaced apart from the opening on the back of the mounting plate corresponding to the mounting cavity.

[0008] The thermostats can be stacked. The opening area of ​​the mounting cavity on the back side of the mounting plate is smaller than the projected area of ​​the receiving part. The opening of the mounting cavity of the upper thermostat on the back side of the mounting plate and the receiving part of the lower thermostat form a limiting structure that prevents the receiving part from entering the mounting cavity from the opening of the mounting cavity.

[0009] The terminal connection part is connected to a rivet, and the terminal connection part is fixed to the mounting plate by the rivet.

[0010] The rivet extends through the back of the mounting plate and connects with the terminal connection. The back of the mounting plate has a countersunk hole corresponding to the rivet head, and the depth of the countersunk hole is greater than the thickness of the rivet head.

[0011] The housing has several horizontally arranged ventilation holes that connect to the mounting cavity. The temperature sensing component is located between the opening on the back side of the mounting plate and the ventilation hole.

[0012] The mounting plate has a mounting boss on one side of the front side, the temperature sensing component and the receiving part are located on the outside of the mounting boss, and the mounting cavity is located on the inside of the mounting boss.

[0013] The mounting boss and mounting plate are integrally molded by injection molding.

[0014] The mounting plate has mounting holes at positions adjacent to the outer side of the mounting boss, and the mounting boss has clearance recesses corresponding to the mounting holes.

[0015] The temperature sensing component is electrically connected to a fuse, which is located on the outside of the housing. The mounting plate has a hollowed-out groove corresponding to the fuse.

[0016] The thermostat of this utility model reduces the chance of physical deformation of the temperature sensing component due to contact and collision by setting an installation cavity. Even when different thermostats are stored together, the housing can provide good protection for the temperature sensing component, thereby improving the product yield. At the same time, by setting an opening, the temperature sensing component is fixed to the front of the mounting plate, which simplifies the installation structure and further reduces the chance of the back of the temperature sensing component being deformed by collision.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-6 This thermostat includes a mounting plate 1 and a temperature sensing component 2 fixedly connected to one side of the front of the mounting plate 1. The mounting plate 1 has a receiving part 3 on the outer side corresponding to the temperature sensing component 2. The receiving part 3 protrudes towards the front of the mounting plate 1. The inner side of the receiving part 3 is hollow and forms a mounting cavity 33 for accommodating the temperature sensing component 2. By setting the mounting cavity 33, the chance of physical deformation of the temperature sensing component 2 due to contact and collision is reduced. Even when different thermostats are stored in a cluster, the receiving part 3 can provide good protection for the temperature sensing component 2, thereby improving the product yield.

[0025] The receiving part 3 has openings 31 on the left and right sides for the temperature sensing component 2 to enter or leave the mounting cavity 33. The temperature sensing component 2 is provided with terminal connection parts 21 on the left and right sides respectively. The terminal connection parts 21 extend outward from the openings 31 respectively. The terminal connection parts 21 are connected and fixed to the front of the mounting plate 1. By providing the openings 31, the temperature sensing component 2 is fixed to the front of the mounting plate 1 as a whole, which simplifies the installation structure and further reduces the chance of the back of the temperature sensing component 2 being deformed by collision.

[0026] The temperature sensing component 2 consists of a moving contact piece, a bimetallic strip, and a moving contact point. This structure is existing technology and will not be described in detail here, but those skilled in the art will understand it.

[0027] The mounting plate 1 has an opening on one side of its back corresponding to the mounting cavity 33. The temperature sensing component 2 and the mounting cavity 33 are spaced apart from this opening on the back of the mounting plate 1, allowing hot air from devices such as heaters to pass through the back of the mounting plate 1 and act on the temperature sensing component 2, enabling the thermostat to detect temperature. Simultaneously, the opening 31 also improves the efficiency of airflow through the temperature sensing component 2, thereby enhancing the accuracy of the temperature sensing component 2 in detecting the airflow temperature.

[0028] The thermostats can be stacked. The opening area of ​​the mounting cavity 33 on the back side of the mounting plate 1 is smaller than the projected area of ​​the receiving part 3. The opening of the mounting cavity 33 of the upper thermostat on the back side of the mounting plate 1 and the receiving part 3 of the lower thermostat form a limiting structure that prevents the receiving part 3 from entering the mounting cavity 33 from the opening of the mounting cavity 33. When the thermostats are stacked and stored, even in the stacked state, the receiving part 3 of the lower thermostat will not enter the opening of the mounting cavity 33 of the upper thermostat, thus avoiding the situation where the receiving part 3 collides with the temperature sensing component 2 in the stacked state, and further reducing the chance of the temperature sensing component 2 being physically deformed due to collision contact.

[0029] The terminal connection part 21 is connected to the rivet 4, and the terminal connection part 21 is connected and fixed to the mounting plate 1 by the rivet 4, thereby improving the connection strength between the terminal connection part 21 and the mounting plate 1.

[0030] The rivet 4 penetrates the mounting plate 1 through the back of the mounting plate 1 and connects with the terminal connection part 21. The back of the mounting plate 1 is provided with a countersunk hole 11 corresponding to the rivet head of the rivet 4. The depth of the countersunk hole 11 is greater than the thickness of the rivet head of the rivet 4 so that the rivet head of the rivet 4 will not occupy the external space of the mounting plate 1, thus avoiding the rivet 4 from affecting the normal installation and connection of the thermostat and external equipment (such as a heater).

[0031] The housing 3 has several horizontally arranged ventilation holes 32, which are connected to the mounting cavity 33. The temperature sensing component 2 is located between the opening on the back side of the mounting plate 1 and the ventilation hole 32 in the mounting cavity 33, which can further improve the efficiency of airflow through the temperature sensing component 2, thereby improving the accuracy of the temperature sensing component 2 in detecting the airflow temperature.

[0032] The mounting plate 1 has a mounting boss 12 on one side of its front side. The temperature sensing component 2 and the receiving part 3 are located on the outside of the mounting boss 12, and the mounting cavity 33 is located on the inside of the mounting boss 12. This relatively increases the thickness of the mounting plate 1, making it easier to install the mounting cavity 33.

[0033] The mounting boss 12 and the mounting plate 1 are integrally molded by injection molding. Compared with the mounting plate 1 which is injection molded using materials such as mica, the cost is lower. Moreover, the mounting boss 12 increases the thickness of the mounting plate 1, which also gives the mounting plate 1 relatively better structural strength.

[0034] Mounting plate 1 has mounting holes 13 located adjacent to the outer side of mounting boss 12. Mounting boss 12 has clearance recesses 121 corresponding to mounting holes 13, which makes it easier for the thermostat to be installed and connected to external equipment (such as a heater). The clearance recesses 121 can make the structural layout of mounting plate 1 more compact, relatively reduce the length of mounting plate 1, and reduce material costs.

[0035] The temperature sensing component 2 is electrically connected to a fuse 5, which is located on the outside of the receiving part 3. The mounting plate 1 has a hollowed-out groove 14 corresponding to the fuse 5. When the temperature sensing component 2 fails, the fuse 5 can cut off the circuit by melting, thus improving the safety of the product. The hollowed-out groove 14 makes the connection structure between the fuse 5 and the mounting plate 1 more compact. Compared with the temperature sensing component 2, the fuse 5 is not easily damaged by contact or collision. Therefore, there is no need to set a protective structure on the outside of the fuse 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claims.
