[0028] like Figure 1 As shown, an embodiment of the utility model provides a plum blossom contact temperature measuring sensor, comprising: a thermally conductive clamp 1, a temperature measuring component 2 and a protective component 3; a clamping structure is provided on the thermally conductive clamp 1, the thermally conductive clamp 1 is clamped on the plum blossom contact 5 along a first direction, the clamping structure is clamped on the plum blossom contact 5 along a second direction, both sides of the protective component 3 are clamped on the thermally conductive clamp 1, the protective component 3 and the thermally conductive clamp 1 form a accommodating cavity, and the temperature measuring component 2 is located in the accommodating cavity.

[0029] In practical applications, such as Figure 2As shown, the plum blossom contact 5 is a plum blossom contact 5 in the prior art. The heat conducting clamp 1 and the clamping structure are both made of metal and have good thermal conductivity. They can transfer the heat of the plum blossom contact 5 to the temperature measuring component 2 to achieve the temperature measurement of the plum blossom contact 5 by the temperature measuring component 2. In this embodiment, the first direction and the second direction are perpendicular to each other. The heat conducting clamp 1 clamps the plum blossom contact 5 in the first direction, and the clamping structure clamps the plum blossom contact 5 in the second direction, so that the plum blossom contact 5 is clamped from two different directions, thereby improving the temperature measurement sensor and the plum blossom contact 5. The connection stability can prevent it from falling off due to vibration, thereby eliminating the risk of short circuit caused by falling off. After the thermal conductive clamp 1 is clamped on the plum blossom contact 5, an installation area is provided on the thermal conductive clamp 1. The temperature measuring component 2 is first placed on the installation area, and then the two sides of the protective component 3 are respectively clamped on the installation area. The installation area and the protective component 3 form a accommodating cavity, so that the temperature measuring component 2 is located in the accommodating cavity. Compared with the installation method of directly fixing the temperature measuring component 2 on the clamp or the plum blossom contact 5 in the prior art, the installation method of the temperature measuring component 2 in this embodiment is convenient and not easy to damage the temperature measuring component 2.

[0030] Furthermore, if Figure 1 As shown, an inverted arch-shaped pressing piece 4 is provided on the protection component 3, and the pressing piece 4 is located in the accommodating cavity. One side of the temperature measuring component 2 is pressed against the heat-conducting clamp 1, and the other side of the temperature measuring component 2 is pressed against the pressing piece 4.

[0031] Specifically, the clamping sheet 4 is elastic, and the inverted arch-shaped clamping sheet 4 is arranged at the top end of the protective component 3 and faces the accommodating cavity. After the protective component 3 is clamped on the heat-conducting clamp 1, due to the elastic effect of the clamping sheet 4, the clamping sheet 4 can be pressed toward the temperature measuring component 2 in the accommodating cavity, so that the clamping sheet 4 is tightly pressed against the temperature measuring component 2, and the temperature measuring component 2 is tightly pressed against the heat-conducting clamp 1, thereby improving the temperature collection reliability and reducing heat transfer losses.

[0032] Furthermore, if Figure 3 As shown, the clamping structure includes: a first clamping pin 14, a second clamping pin 15 and a spring 16; the spring 16 is arranged at the top of the thermal conductive clamp 1, the first clamping pin 14 is arranged at the bottom end of one side of the thermal conductive clamp 1, and the second clamping pin 15 is arranged at the bottom end of the other side of the thermal conductive clamp 1, the spring 16 is tightly pressed against the top of the plum blossom contact 5, and the first clamping pin 14 and the second clamping pin 15 are both tightly pressed against the bottom end of the plum blossom contact 5.

[0033] Specifically, in the present embodiment, one side of the thermally conductive clamp 1 is a clamping side of the thermally conductive clamp 1, and the other side of the thermally conductive clamp 1 is another clamping side of the thermally conductive clamp 1. After the thermally conductive clamp 1 is clamped onto the plum blossom contact 5, the thermally conductive clamp 1 clamps the left and right sides of the plum blossom contact 5, and the first clamping foot 14, the second clamping foot 15 and the spring piece 16 cooperate to clamp the upper and lower sides of the plum blossom contact 5. The elastic force of the spring piece 16 can press the plum blossom contact 5 against the first clamping foot 14 and the second clamping foot 15, which can further prevent it from falling off the plum blossom contact 5, and also increase the contact area with the plum blossom contact 5, reduce heat transfer loss, and improve temperature collection reliability.

[0034] Furthermore, if Figure 3 As shown, the first clamping pin 14 is formed by continuously bending the bottom end of one side of the thermal conductive clamp 1 inward, and the first clamping pin 14 formed by continuously bending inward has a first plane 141 and a first inclined surface 142. The first plane 141 is tightly pressed against the bottom end of the plum blossom contact 5, and the first inclined surface 142 gradually approaches the inner side of the thermal conductive clamp 1 from bottom to top.

[0035] Specifically, the first clamping pin 14 is formed by bending the bottom end of the first clamp 12 inward twice continuously. The first bend forms the first inclined surface 142 of the first clamping pin 14, and the second bend forms the first plane 141 of the first clamping pin 14. The first plane 141 is tightly pressed against the bottom end of the plum blossom contact 5, thereby increasing the contact area with the plum blossom contact 5, making it easier for the thermal conductive clamp 1 to transfer the temperature of the plum blossom contact 5 to the temperature measuring component 2. The first inclined surface 142 is gradually approached from bottom to top by the inclined surface setting on the inner side of the thermal conductive clamp 1, so that the plum blossom contact 5 is clamped into the thermal conductive clamp 1.

[0036] Furthermore, if Figure 3 As shown, the second clamping pin 15 is formed by continuously bending inwardly at the bottom end of the other side of the thermally conductive clamp 1. The second clamping pin 15 formed by continuously bending inwardly has a second plane 151 and a second inclined surface 152. The second plane 151 is tightly pressed against the bottom end of the plum blossom contact 5, and the second inclined surface 152 gradually approaches the inner side of the thermally conductive clamp 1 from bottom to top.

[0037] Specifically, the second clamping pin 15 is formed by bending the bottom end of the second clamp 13 inward twice continuously. The first bend forms the second inclined surface 152 of the second clamping pin 15, and the second bend forms the second plane 151 of the second clamping pin 15. The second plane 151 is tightly pressed against the bottom end of the plum blossom contact 5, thereby increasing the contact area with the plum blossom contact 5, making it easier for the thermal conductive clamp 1 to transfer the temperature of the plum blossom contact 5 to the temperature measuring component 2. The second inclined surface 152 is gradually set close to the inner side of the thermal conductive clamp 1 from bottom to top, which further facilitates the clamping of the plum blossom contact 5 into the thermal conductive clamp 1.

[0038] Furthermore, if Figure 3As shown, the heat-conducting clamp 1 includes: a connecting piece 11, a first clamp 12 and a second clamp 13; the first clamp 12 is arranged on one side of the connecting piece 11, and the second clamp 13 is arranged on the other side of the connecting piece 11, the first clamp 12, the connecting piece 11 and the second clamp 13 form a U-shaped clamp, the first clamp 12 is pressed against one side of the plum blossom contact 5, and the second clamp 13 is pressed against the other side of the plum blossom contact 5, the spring 16 is arranged on the connecting piece 11, the first clamping foot 14 is arranged at the bottom end of the first clamp 12, and the second clamping foot 15 is arranged at the bottom end of the second clamp 13, one side of the protective component 3 is clamped with the first clamp 12, and the other side of the protective component 3 is clamped with the second clamp 13, and the protective component 3 and the connecting piece 11 form a accommodating cavity.

[0039] In actual applications, the first clip 12 and the second clip 13 are respectively formed by bending the connecting piece 11, and the first clip 12 and the second clip 13 are both integrally connected to the connecting piece 11, thereby improving the firmness of the heat-conducting clamp 1. The U-shaped clamp formed by the first clip 12, the connecting piece 11 and the second clip 13 can clamp the plum blossom contact 5. In this embodiment, two spring clips 16 are provided, and the two spring clips 16 are respectively extended outward from both ends of the connecting piece 11 and bent backward. In other embodiments, a spring clip 16 can be provided, extending from any end of the connecting piece 11 and bending backward.

[0040] Furthermore, if Figure 3 As shown, the first clamping piece 12 defines a first clamping hole 121 , the second clamping piece 13 defines a second clamping hole 131 , one side of the protection component 3 is clamped in the first clamping hole 121 , and the other side of the protection component 3 is clamped in the second clamping hole 131 .

[0041] Specifically, by setting the first snap-in hole 121 and the second snap-in hole 131, it is convenient for the two sides of the protective component 3 to be respectively snapped into the first snap-in hole 121 and the second snap-in hole 131. The first snap-in hole 121 is formed by cutting one side of the connecting piece 11 along a U-shaped line and then bending, and the second snap-in hole 131 is formed by cutting the other side of the connecting piece 11 along a U-shaped line and then bending, so that part of the metal sheet is left above the first snap-in hole 121 and the second snap-in hole 131, so that the two metal sheets can respectively play a good snapping role on the two sides of the protective component 3.

[0042] Furthermore, if Figure 4As shown, the protection component 3 includes: a first extension plate 31, a second extension plate 32 and a frame body 33; one end of the first extension plate 31 is fixedly connected to one side of the frame body 33, and the other end of the first extension plate 31 is provided with a first clamping block 311, one end of the second extension plate 32 is fixedly connected to the other side of the frame body 33, and the other end of the second extension plate 32 is provided with a second clamping block 321, the first clamping block 311 and the second clamping block 321 are both clamped on the heat-conducting component, one side of the clamping plate is provided at one end of the frame body 33, and the other side of the clamping plate is provided at the other end of the frame body 33.

[0043] In actual application, the first clamping block 311 is clamped with the first clamping hole 121, and the second clamping block 321 is clamped with the second clamping hole 131. One side of the clamping plate 4 is arranged at one end of the frame 33, and the other side of the clamping plate 4 is arranged at the other end of the frame 33. By setting the first extension plate 31 and the second extension plate 32, the position of the frame 33 is raised, so that a receiving cavity for placing the temperature measuring component 2 can be reserved between the protective component 3 and the thermal conductive clamp 1. Through the setting of the frame 33, the inverted arch-shaped clamping plate 4 can face the receiving cavity and be partially located in the receiving cavity to compress the temperature measuring component 2 in the receiving cavity, so that the temperature measuring component 2 is pressed against the thermal conductive clamp 1 to ensure the temperature collection effect.

[0044] Furthermore, if Figure 4 As shown, the first extension plate 31 has first openings 312 on both sides close to the first clamping block 311, and the second extension plate 32 has second openings 322 on both sides close to the second clamping block 321. In practical applications, the first openings 312 on both sides of the first clamping block 311 facilitate the first clamping block 311 to be clamped into the first clamping hole 121, and the second openings 322 on both sides of the second clamping block 321 facilitate the second clamping block 321 to be clamped into the second clamping hole 131.

[0045] Furthermore, in this embodiment, the temperature measuring component 2 adopts a temperature measuring electronic tag, such as an RFID (Radio Frequency Identification) temperature measuring electronic tag, which is passive, battery-free, maintenance-free, and provides real-time temperature detection, such as Figure 3 As shown, the protection component 3 and the pressing plate are made of non-metallic materials, such as plastic. Compared with the solution in the prior art that the spring clip uses metal to wrap or semi-wrap the temperature measuring component to fix the temperature measuring component, the utility model can prevent the shielding problem of the electromagnetic signal sent or received by the temperature measuring component 2, thereby improving the reliability and stability of the product.

[0046] The plum blossom contact temperature sensor of the utility model clamps the plum blossom contact 5 in a first direction by the heat-conducting clamp 1, and clamps the plum blossom contact 5 in a second direction by the clamping structure, thereby clamping the plum blossom contact 5 from two different directions, thereby improving the connection stability between the temperature sensor and the plum blossom contact 5, and can prevent it from falling off due to vibration, thereby eliminating the short circuit risk caused by falling off. The two sides of the protective component 3 are clamped on the heat-conducting clamp 1, and the heat-conducting clamp 1 and the protective component 3 form a accommodating cavity, so that the temperature measuring component 2 is located in the accommodating cavity. Compared with the installation method of directly fixing the temperature measuring component 2 on the clamp or the plum blossom contact 5 in the prior art, the installation method of the temperature measuring component 2 of the utility model is convenient and not easy to damage the temperature measuring component 2.

[0047] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.
