[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1 , Figure 2As shown, this embodiment discloses a thermocouple wiring bracket, including a bracket 3. The bracket 3 includes a first frame 31 and a second frame 33, which are located at opposite ends of the bracket 3 along its length. The first frame 31 and the second frame 33 are used to support the thermocouple compensating wire 1 and the thermocouple wire 2, respectively. One bracket 3 corresponds to one thermocouple compensating wire 1 and one thermocouple wire 2. Specifically, as... Figure 2 , Figure 3 As shown, the first frame 31 includes a first support plate 312 and a first extension plate 311 located on both sides of the first support plate 312. The thermocouple wire 2 abuts against the first support plate 312, and the first extension plate 311 is bent and clamped to the outer wall of the thermocouple wire 2 to fix the thermocouple wire 2.
[0022] like Figure 2 , Figure 4 As shown, the second frame 33 includes a second support plate 332 and a second extension plate 331 located on both sides of the second support plate 332. The thermocouple compensation wire 1 abuts against the second support plate 332, and the second extension plate 331 is bent and clamped to the outer wall of the thermocouple compensation wire 1 to fix the thermocouple compensation wire 1.
[0023] like Figure 2 As shown, the thermocouple wire 2 includes pins 21, which are located between the thermocouple compensating wire 1 and the thermocouple wire 2. Specifically, the thermocouple compensating wire 1 includes two wires, and there are two pins 21, with one pin 21 corresponding to one wire. The pins 21 extend out of the thermocouple wire 2 and are electrically connected to the thermocouple compensating wire 1.
[0024] The bracket 3 includes a third frame 32, which is located between the first frame 31 and the second frame 33. The third frame 32 has a groove 321 on the side facing the pin 21. Since the pin 21 and the thermocouple compensation wire 1 need to be wrapped with glue, the groove 321 serves to support the glue and facilitates the application of glue. At the same time, the groove 321 also provides space for the glue.
[0025] The third frame 32 is arc-shaped on the side away from pin 21 to facilitate the installation of the cold junction cap 4. The third frame 32 is inserted into the cold junction cap 4, which is located inside the bracket 3. Thermocouple wire 2 extends from one end of the cold junction cap 4, and thermocouple compensating wire 1 extends from the other end of the cold junction cap 4. The cold junction cap 4 and the bracket 3 are pressed together and fixed in place.
[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
