[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] The preferred implementation of the utility model is now further described in conjunction with the accompanying drawings. Figure 1As shown, a temperature controller includes a shell 10, an insulating fixing seat 100 is arranged in the shell 10, a static contact piece 200 is fitted and installed at the bottom of the insulating fixing seat 100, a fixing plate 300 is arranged on the top of the insulating fixing seat 100, a moving contact piece 400 is fitted at the bottom of the fixing plate 300, the static contact piece 200 and the moving contact piece 400 are respectively in electrical contact with an external circuit, a through groove 110 is arranged on the insulating fixing seat 100, under normal conditions, the moving contact piece 400 passes through the through groove 110 and contacts with the static contact piece 200, when the current or voltage of the external circuit is overloaded, the temperature of the moving contact piece 400 increases and deforms, so that the moving contact piece 400 is out of contact with the static contact piece 200, thereby disconnecting the entire circuit, and then controlling the conduction of the entire circuit by temperature, on both sides of the fixing plate 300 A snap fastener 310 is respectively provided, and an embedding piece 120 is respectively provided on both sides of the insulating fixing seat 100. When the fixing plate 300 needs to be installed on the top of the insulating fixing seat 100, it is only necessary to press the fixing plate 300 toward the insulating fixing seat 100 to embed the embedding piece 120 into the snap fastener 310, thereby fixing the insulating fixing seat 100 and the fixing plate 300 together. Compared with the technology, the fixing plate 300 and the insulating fixing seat 100 are fixed together by a snap fastener structure. Firstly, it makes it convenient to assemble the two during production, and the operator can assemble the two together without any tools, thereby improving production efficiency. Secondly, by assembling together through the snap fastener structure, the connection between the fixing plate 300 and the insulating fixing seat 100 can be made more resistant to vibration, and the two are not allowed to fall off during long-term use.

[0030] Based on the above embodiments, Figure 1 As shown, the fastener 310 is a clamping ring extending downward along the fixing plate 300, and the insert 120 is a hook extending outward along the insulating fixing seat 100. When the fixing plate 300 is pressed toward the insulating fixing seat 100, the hook is embedded in the clamping ring from the inner side, thereby fixing the insulating fixing seat 100 and the fixing plate 300 together.

[0031] Preferably, Figure 1 As shown, there are four snap members 310 and four insert members 120 , respectively, and two are disposed on each side of the fixing plate 300 and the insulating fixing seat 100 , so that the fixing effect between the insulating fixing seat 100 and the fixing plate 300 can be better.

[0032] Based on the above embodiments, Figure 1 and Figure 2As shown, a surrounding body 130 is arranged around the top of the insulating fixing seat 100. When the fixing plate 300 and the insulating fixing seat 100 are installed and fixed together, the movable contact piece 400 is accommodated in the interior of the surrounding body 130. In this way, the surrounding body 130 can surround the movable contact piece 400, which can effectively prevent the movable contact piece 400 from swinging around when the temperature rises and deformation occurs, thereby affecting the control effect. Based on this embodiment, the through groove 110 is arranged at the bottom of the surrounding body 130, and the embedded part 120 is arranged around the outer side of the surrounding body 130.

[0033] Based on the above embodiments, Figure 3 As shown, a first limit block 320 is provided at the bottom of the fixed plate 300, and a first limit groove 410 matching the shape of the first limit block 320 is provided at the corresponding position of the movable contact piece 400. When the movable contact piece 400 is attached to the bottom of the fixed plate 300, the first limit groove 410 is inserted into the fixed first limit block 320, so that the installation position between the movable contact piece 400 and the fixed plate 300 is more precise.

[0034] On the basis of the above embodiment, a positioning block 330 protrudes downward from the bottom of the fixed plate 300. When the movable contact piece 400 is attached to the bottom of the fixed plate 300, the positioning block 330 pushes the movable contact piece 400 downward to deform it into a curved shape so that it can come into contact with the stationary contact piece 200.

[0035] Based on the above embodiments, Figure 3 As shown, a contact 420 protrudes downward at one end of the moving contact piece 400 , and the contact 420 can shorten the bending degree of the moving contact piece 400 . When the moving contact piece 400 passes through the through slot 110 , the contact 420 comes into contact with the stationary contact piece 200 .

[0036] Based on the above embodiments, Figure 4 As shown, a second limiting block 140 is provided at the bottom of the insulating fixing seat 100, and a second limiting groove 210 matching the shape of the second limiting block 140 is provided at the corresponding position of the static contact piece 200. When the static contact piece 200 is attached to the bottom of the insulating fixing seat 100, the second limiting groove 210 is inserted into and fixed in the second limiting block 140, so that the installation position between the static and movable contact pieces 400 and the insulating fixing seat 100 is more accurate.

[0037] Based on the above embodiments, Figure 3 and Figure 4 As shown, the fixing plate 300 and the stationary contact piece 200 are both provided with a connecting piece 220 for connecting to an external circuit.

[0038] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
