It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0041] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0042] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0043] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0044] like Figure 1-13 As shown, an embodiment of this utility model provides a temperature-sensitive connector, which includes a housing 1, a terminal 2, and a temperature-sensing mechanism. The terminal 2 is installed in the housing 1. The temperature-sensing mechanism includes a fixing member 4, a temperature sensor 7, and a signal wire. The fixing member 4 is connected to the housing 1. The temperature sensor 7 is fixedly mounted on the fixing member 4 and extends toward the terminal 2. The signal wire is electrically connected to the temperature sensor 7. In addition, the temperature sensor 7 is thermally connected to the terminal 2.

[0045] In this solution, the fixing component 4 can more effectively fix the temperature sensor 7, enabling it to stably sense the temperature of the terminal 2. It is not easily interfered with or damaged by external vibrations or other adverse factors, resulting in better stability and more accurate output temperature signals.

[0046] Furthermore, in order to enable the temperature sensor 7 to acquire the temperature of terminal 2 more uniformly and accurately, such as... Figure 6-8 As shown, in this embodiment, the side of the terminal 2 facing the temperature sensor 7 is provided with an inwardly recessed receiving groove 21. The receiving groove 21 can be formed by stamping a groove structure that does not penetrate the terminal 2 on the terminal 2. The temperature sensor 7 is received in the receiving groove 21 so that the terminal 2 can provide enveloping temperature transmission to the temperature sensor 7, minimizing the influence of external factors on the temperature sensor 7 and improving the accuracy of the temperature signal of the temperature sensor 7. In addition, a heat-conducting structure is provided between the temperature sensor 7 and the receiving groove 21 to further dampen, fix and improve the heat conduction effect of the temperature sensor 7.

[0047] To further improve the fixing and support effect of the fastener 4 on the temperature sensor 7, such as Figure 9-12 As shown, in this embodiment, the fixing member 4 is provided with a support portion 41 that extends toward the receiving groove 21 and at least its end extends toward the receiving groove 21. In fact, the end of the support portion 41 has already extended into the receiving groove 21. The temperature sensor 7 is located at the end of the support portion 41 and is supported and cooperated with the end of the support portion 41 in the direction of exiting the receiving groove 21.

[0048] To further stabilize the support of temperature sensor 7, such as Figure 9-12As shown, in this embodiment, the end of the support part 41 is provided with a bearing groove 43 that is adapted to the shape of the temperature sensor 7, and the temperature sensor 7 is at least partially embedded in the bearing groove 43.

[0049] In this embodiment, the thermally conductive structure is a thermally conductive silicone block 6 inserted into the receiving groove 21. That is, the thermally conductive silicone is first molded onto the temperature sensor 7 and then inserted into the receiving groove 21.

[0050] In other embodiments, other suitable thermally conductive materials can be used to construct the thermally conductive structure. Alternatively, the temperature sensor can be inserted into the receiving groove first, and then the suitable thermally conductive material can be injected into the gap between the temperature sensor and the receiving groove.

[0051] Furthermore, in order to fix the thermally conductive silicone block 6 to the fixing member 4, such as... Figure 10 As shown, in this embodiment, the fixing member 4 is provided with a positioning hole 42 near the terminal 2, and the thermally conductive silicone block 6 extends to the positioning hole 42 and is provided with a positioning part 61 that is embedded in the positioning hole 42.

[0052] Furthermore, considering structural simplification and ease of assembly, such as Figure 6 , 11 As shown, in this embodiment, the fixing member 4 is a circuit board with a pre-set conductive line. The temperature sensor 7 includes two electrical pins. The electrical pins are fixed on the circuit board and electrically connected to the conductive line. That is, the fixing and electrical connection of the electrical pins can be achieved by soldering. One end of the signal wire is electrically connected to the conductive line to realize the electrical connection between the signal wire and the temperature sensor 7.

[0053] Furthermore, considering ease of assembly and structural simplicity, such as Figure 1 , 3 As shown in Figures 5 and 6, in this embodiment, the signal wire is a pin-shaped terminal 12. The pin-shaped terminal 12 is fixed inside the housing 1, with one end electrically connected to the conductive line on the circuit board and the other end forming a signal output terminal. In fact, in this embodiment, the housing 1 is also provided with a low-voltage interface 11. The other end of the pin-shaped terminal 12, i.e. the signal output terminal, is located inside the low-voltage interface 11. The pin-shaped terminal 12 is embedded in the housing 1 and injection molded. One end of the pin-shaped terminal 12 is electrically connected to the conductive line on the circuit board through a conventional plug-in conductive connection method or a solder conductive connection method.

[0054] Furthermore, considering the ease of assembly and disassembly, such as Figure 3 , 5 As shown in Figures 6 and 7, in this embodiment, the fastener 4 is detachably connected to the housing 1 by a bolt structure, which includes a bolt 5 and a nut 51 embedded in the housing 1.

[0055] Furthermore, considering the protection of fastener 4, such as Figure 2 ,5 As shown in Figures 1 and 13, in this embodiment, the housing 1 is provided with a protective cover 3 covering the outside of the fixing member 4. The protective cover 3 can be fixedly connected to the housing 1 through a buckle 31 structure. The buckle 31 structure includes a buckle 31 on the protective cover 3 and a locking platform 13 on the housing 1.

[0056] In this embodiment, there are two terminals 2, and the temperature sensing mechanism has a temperature detection relationship with only one of the terminals 2.

[0057] The reference assembly steps for this temperature-sensitive connector are as follows.

[0058] First, solder the pins of the temperature sensor 7 to the fixing part 4, i.e., the circuit board, and make the temperature sensor 7 cooperate with the bearing groove 43 of the support part 41.

[0059] 2. Install the thermally conductive silicone block 6 onto the fixing part 4 and wrap it around the temperature sensor 7.

[0060] 3. Insert the thermally conductive silicone block 6 into the receiving groove 21 of the terminal 2 until the temperature sensor 7 is received in the receiving groove 21.

[0061] Fourth, insert and fix the terminal 2 into the housing 1. At this time, the fixing member 4 is attached to the housing 1, and one end of the needle terminal 12 is inserted and connected to the corresponding position of the fixing member 4.

[0062] 5. The fastener 4 is connected to the housing 1 by bolts.
