Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a temperature controller. Background Art

[0002] A thermostat is a controller that uses a bimetallic strip as a temperature-sensing component. When the appliance is working normally, the bimetallic strip is in a free state and the contacts are in a closed / open state. When the temperature reaches the operating temperature, the bimetallic strip is heated and generates internal stress, causing it to move quickly, opening / closing the contacts and cutting off / connecting the circuit, thereby controlling the temperature. When the appliance cools to the reset temperature, the contacts automatically close / open and resume normal operation.

[0003] It is widely used in: water dispensers, water heaters, sandwich toasters, dishwashers, dryers, disinfection cabinets, microwave ovens, electric coffee makers, electric cookers, refrigerators, air conditioners, laminators, office equipment, car seat heaters and other electric heating appliances.

[0004] However, the current wiring method of thermostats is: the circuit wires are riveted to the plug-in terminals, and then the plug-in terminals are inserted into the wiring terminals extending from the thermostat body to achieve circuit connectivity; the plug-in method will cause the contact resistance to increase due to reasons such as uneven contact surface or oxidation of the metal surface, thereby causing the contact resistance to overheat and even cause electrical fires. Utility Model Content

[0005] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, the present application proposes a temperature controller.

[0007] In view of this, the present application provides a thermostat, comprising a thermostat body and a terminal extending from the thermostat body, wherein a riveting assembly is provided at an end of the terminal away from the thermostat body, the riveting assembly comprising:

[0008] The wire core barrel is connected to the terminal away from the thermostat body;

[0009] The insulating sheath barrel is connected to the end of the wire core barrel away from the thermostat body, and an insulating skin observation port is left between the insulating sheath barrel and the wire core barrel.

[0010] By adopting the above technical solution, the wire core barrel must be completely closed and contain all wire cores, and the insulation cannot be seen; the insulation barrel must be riveted tightly, and the wire cannot move; the insulation observation port is the upper opening of the connection between the wire core barrel and the insulation barrel, which is used to observe the wire core and the insulation. In the riveting specification, the wire core and the insulation must be visible at the connection between the wire core barrel and the insulation barrel at the same time; the provision of the insulation observation port can better regulate the thermostat of this solution during riveting.

[0011] The utility model is further configured as follows: arc-shaped flanges are extended outwards at both ends of the wire core barrel.

[0012] By adopting the above technical solution, the provision of a curved flange also helps to enhance the connection strength between the wire core and the terminal, and improve the reliability and stability of the connection; it also helps to form a better sealing performance during the crimping process, preventing moisture or other external factors from damaging the wire core, thereby protecting the long-term stable use of the wire core.

[0013] The utility model is further configured as follows: a positioning baffle is provided on the wire core barrel near the end of the thermostat body, and the positioning baffle is 0.2-1.0 mm away from the end of the wire core barrel.

[0014] By adopting the above technical solution, the distance that the wire core extends must follow certain standards. Therefore, setting a positioning baffle 4 can better standardize the operation to ensure that the wire core can be correctly fixed during the riveting process, and will not cause poor connection or wire core damage due to an extension distance that is too short or too long.

[0015] The utility model is further configured as follows: a protection plate is extended outwardly from the end of the insulating sheath barrel away from the wire core barrel, and the protection plate is arranged in an arc shape.

[0016] By adopting the above technical solution, the arc-shaped protection plate 321 can effectively protect the wire from breaking or cracking of the insulation during the back-and-forth swinging process.

[0017] The utility model is further configured as follows: the insulation skin observation port is provided with a positioning protrusion.

[0018] The utility model is further configured as follows: the positioning protrusion is located in the middle of the insulation skin observation port.

[0019] By adopting the above technical solution, when the wire is inserted into the riveting assembly 3, it can be accurately positioned so that the wire core and the insulation skin at the insulation skin observation port 33 each occupy half, thereby achieving standardization of riveting.

[0020] In summary, the beneficial technical effects of the present invention are:

[0021] The provision of the insulation skin observation port 33 can better regulate the thermostat of this solution during riveting;

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 、 Figure 2 and Figure 3 , is a thermostat disclosed in the present utility model, comprising a thermostat body 1 and a terminal 2 extending from the thermostat body 1, a riveting assembly 3 is provided at the end of the terminal 2 away from the thermostat body 1, and the riveting assembly 3 comprises: a wire core barrel 31, connected to the end of the terminal 2 away from the thermostat body 1; an insulating sheath barrel 32, connected to the end of the wire core barrel 31 away from the thermostat body 1, and an insulating skin observation port 33 is left between the insulating sheath barrel 32 and the wire core barrel 31.

[0030] In this embodiment, the wire core barrel 31 must be completely closed and contain all the wire cores, and the insulation cannot be seen; the insulation barrel 32 must be riveted tightly, and the wire cannot move; the insulation observation port 33 is the upper opening of the connection between the wire core barrel 31 and the insulation barrel 32, which is used to observe the wire core and the insulation. In the riveting specification, the wire core and the insulation must be visible at the connection between the wire core barrel 31 and the insulation barrel 32 at the same time; the provision of the insulation observation port 33 can well regulate the thermostat of this solution during riveting.

[0031] At the same time, arc-shaped flanges 311 extend outward from both ends of the wire core barrel 31, so that the wire core barrel 31 will form a bell mouth at the front and back ends after the wire core is crimped. This is to ensure that the wire core can better enter the crimping area during the crimping process; at the same time, the provision of the arc-shaped flanges 311 also helps to enhance the connection strength between the wire core and the terminal 2, and improve the reliability and stability of the connection.

[0032] In this embodiment, the thickness of the wire core will be reduced after the wire core sleeve 31 is crimped, forming a height difference with the uncrimped wire core, so the wire core will have an arc at the crimped connection. Therefore, providing an arc-shaped flange 311 to form a bell mouth after crimping also helps to form a better sealing performance during the crimping process, preventing moisture or other external factors from damaging the wire core, thereby protecting the long-term stable use of the wire core.

[0033] In this embodiment, a positioning baffle 4 is further provided at the end of the wire core barrel 31 close to the thermostat body 1 , and the positioning baffle 4 is 0.2-1.0 mm away from the end of the wire core barrel 31 .

[0034] In the riveting specification, the wire core must extend a certain distance beyond the end of the wire core barrel 31. This is to ensure that the wire core can be properly fixed and connected during the riveting process, to avoid the wire core breaking or not being pressed by the wire core barrel 31, and to ensure the reliability and safety of the electrical connection. Specifically, the distance the wire core extends must comply with certain standards. Therefore, the provision of a positioning baffle 4 can better regulate the operation, ensuring that the wire core can be properly fixed during the riveting process, and preventing poor connection or wire core damage due to an excessively short or long extension distance.

[0035] In this embodiment, a protective plate 321 extends outward from the end of the insulating sheath tube 32 away from the wire core sheath tube 31, and the protective plate 321 is arranged in an arc shape; the arc-shaped protective plate 321 can effectively protect the wire from breaking or cracking of the insulation during the back and forth swinging process.

[0036] A positioning protrusion 5 is provided at the insulation skin observation port 33 ; and the positioning protrusion 5 is located in the middle of the insulation skin observation port 33 , that is, the positioning protrusion 5 is equidistant from the wire core barrel 31 and the insulation barrel 32 .

[0037] In this embodiment, the insulation observation port 33 is the upper opening of the connection between the wire core barrel 31 and the insulation barrel 32, and the positioning protrusion 5 is arranged on the inner wall of the connection between the wire core barrel 31 and the insulation barrel 32, and two positioning protrusions are arranged symmetrically on the left and right; the protrusion height of the positioning protrusion 5 is less than or equal to the thickness of the insulation, so that it can be accurately positioned when the wire is inserted into the riveting assembly 3, so that the wire core and the insulation of the wire at the insulation observation port 33 each occupy half, so as to achieve the standardization of riveting.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
