[0035] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0036] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a test fixture 100 of an electronic thermometer includes a first main body 10, a plurality of heat-conducting needle columns 13 are mounted on the first main body 10, and a test contact point is formed on each heat-conducting needle column 13;

[0037] It also includes a second main body 20, which is installed on the first main body 10. The second main body 20 is used to install the electronic component to be tested. When the first main body 10 and the second main body 20 are assembled with each other, the test contact points on the thermal conductive needle column 13 are respectively in contact with the detection probe of the electronic component to be tested for temperature measurement. In this embodiment, the electronic component to be tested can be a wireless electronic thermometer 200, which has a temperature probe sensor. When the thermal conductive needle column 13 contacts the temperature probe sensor of the wireless electronic thermometer 200, temperature measurement can be performed.

[0038] like Figure 3 As shown, in order to achieve fixed installation of the thermal needle column 13, in this embodiment, the first main body 10 includes a fixing plate 11, and each thermal needle column 13 is fixedly installed on the fixing plate 11. The thermal needle column 13 can be provided in plurality, so that a plurality of wireless electronic thermometers 200 can be synchronously tested at the same time, thereby speeding up the test efficiency. The number of wireless electronic thermometers 200 can be installed and fixed according to the test needs, and the entire second main body 20 can be filled, or only a portion can be loaded for testing, that is, temperature measurement can be performed regardless of whether it is full or not.

[0039] Furthermore, the first main body 10 also includes at least one insulation board 12. In this embodiment, the insulation board 12 is one piece, and the insulation board 12 is installed on the side of the fixed plate 11 close to the second main body 20, and each heat-conducting needle column 13 passes through the fixed plate 11 and the insulation board 12 respectively, and extends toward the second main body 20. The insulation board 12 is used to reduce the scattering of heat, play a heat-insulating role, and protect the wireless electronic thermometer 200.

[0040] In this embodiment, the heat-conducting needle column 13 adopts a copper column, and each heat-conducting needle column 13 is fixedly installed in a matrix. Since copper has extremely high thermal conductivity, its thermal conductivity coefficient is about 400 W / m·K. Compared with other metal materials such as aluminum (thermal conductivity coefficient is about 237 W / m·K) and stainless steel (thermal conductivity coefficient is about 16 W / m·K), copper can conduct heat more efficiently, so that the heat-conducting needle column 13 has a significant advantage in transferring heat, and can quickly transfer heat from a high-temperature area to a low-temperature area, thereby improving the heat dissipation effect of the overall device;

[0041] The matrix arrangement helps to quickly distribute the heat generated by the heat source to the entire heat dissipation area. Since each thermal conductive pin 13 is in a fixed position in the matrix, this arrangement can maximize the thermal conductivity of the thermal conductive pin 13 and transfer heat evenly in the shortest time.

[0042] like Figure 4 and Figure 5 As shown, in this embodiment, the second main body 20 includes a test carrier 22, and the test carrier 22 has an installation buckle position 222. The wireless electronic thermometer 200 can be installed in the installation buckle position 222. The wireless electronic thermometer 200 can fill the installation buckle position 222 or only partially fill it for testing;

[0043] Among them, when the first main body 10 and the second main body 20 are assembled with each other, the test contact point on the heat-conducting needle column 13 is inserted into the installation buckle position 222, and contacts with the detection probe of the wireless electronic thermometer 200 for temperature measurement. By comparing the reading of the wireless electronic thermometer 200 with the actual temperature of the heat-conducting needle column 13, it is determined whether the wireless electronic thermometer 200 is qualified. The temperature measurement is completed by contact, so it is more convenient to separate, there is no plug-in action, and wear is reduced;

[0044] The second main body 20 also includes a pressing plate 23, which is detachably connected to the test carrier 22 and presses each wireless electronic thermometer 200 located in the mounting buckle 222 through the pressing plate 23 to avoid poor contact caused by vibration of the test fixture 100, thereby ensuring the accuracy and reliability of the test results.

[0045] Furthermore, the pressing plate 23 and the test carrier 22 are connected by magnetic attraction. Specifically, a first magnetic attraction block can be embedded in the test carrier 22, and a second magnetic attraction block can be embedded in the pressing plate 23. The pressing plate 23 and the test carrier 22 are magnetically attracted by the first magnetic attraction block and the second magnetic attraction block, which is convenient for disassembly and assembly, and is convenient for placing and taking out each wireless electronic thermometer 200.

[0046] In addition, a buffer gasket 24 is provided at the connection position between the pressing plate 23 and the test carrier 22 to achieve fixation and buffering to prevent loosening. The number of the buffer gasket 24 can be one or more.

[0047] In this embodiment, a handle 231 is provided on the pressing plate 23 to facilitate the placement and removal of each wireless electronic thermometer 200 .

[0048] In this embodiment, the second main body 20 is detachably connected to the first main body 10 , and the second main body 20 has handles 21 on both sides to facilitate installation and removal of the second main body 20 .

[0049] The first main body 10 is provided with a plurality of guide posts 14, and a guide hole 221 is provided on the second main body 20 corresponding to each guide post 14, or the second main body 20 is provided with a plurality of guide posts 14, and a guide hole 221 is provided on the first main body 10 corresponding to each guide post 14. In this embodiment, Figure 2-Figure 5 As shown, the guide column 14 is arranged on the first main body 10, the guide hole 221 is arranged on the second main body 20, and the first main body 10 and the second main body 20 are installed in alignment through the guide column 14 and the guide hole 221. Of course, in other embodiments, the setting positions of the guide column 14 and the guide hole 221 can also be interchanged, and the guide hole 221 and the guide column 14 can be used to complete the positioning and assembly of the two.

[0050] The utility model provides a testing device for an electronic thermometer, comprising the above-mentioned testing tool 100 and a constant temperature bath, wherein a first main body 10 is placed in the constant temperature bath and heat is conducted to a set temperature through a heat-conducting needle column 13, and then a second main body 20 is placed, and a probe of a wireless electronic thermometer 200 contacts the heat-conducting needle column 13 for temperature measurement, and the reading of the wireless electronic thermometer 200 is compared with the actual temperature of the heat-conducting needle column 13.

[0051] The test method of the electronic thermometer is as follows: 1. Add working medium into the constant temperature bath and turn on the power; 2. Place the first main body 10 into the constant temperature bath, start the constant temperature bath and set the test temperature; 3. Confirm and monitor the test temperature until the temperature in the constant temperature bath and the temperature of the thermal needle column 13 are close to the set temperature; 4. Place the wireless electronic thermometer 200 into the second main body 20 and start the test; 5. Read the reading of the wireless electronic thermometer 200 and compare it with the set temperature to obtain the test result.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model.
