[0032] The object of the present utility model is to provide an aging test fixture detection container to achieve effective isolation between the control part and the heating part during the aging test fixture detection process.
[0033] Please refer to Figures 1 to 3 , Figure 1 is a side cross-sectional view of the aging test fixture detection container provided by an embodiment of the present utility model; Figure 2 is a front cross-sectional view of the aging test fixture detection container provided by an embodiment of the present utility model; Figure 3 is a top cross-sectional view of the aging test fixture detection container provided by an embodiment of the present utility model; as Figures 1 to 3As shown in the figure. To achieve the above object, the present utility model provides an aging test fixture detection container, which includes a first cylinder 1 and a second cylinder 2. A controller 11 and / or a power supply 12 are provided in the first cylinder 1. The second cylinder 2 is used to accommodate the aging test fixture 3. The aging test fixture 3 itself has a heating module. The controller 11 can be communicatively connected to the aging test fixture 3.
[0034] Further, please continue to refer to Figure 2 and Figure 3 . As Figure 2 and Figure 3 shown, the controller 11 is provided on a functional base plate 10. The aging test fixture 3 can be installed on the functional base plate 10 so that the controller 11 is communicatively connected to the aging test fixture 3. A partition 20 is provided between the first cylinder 1 and the second cylinder 2. The functional base plate 10 passes through the partition 20. A plurality of mounting portions 23 are provided on the functional base plate 10 located in the second cylinder 2. The mounting portions 23 are used to mount the aging test fixture 3. It should be understood that the functional base plate 10 can be an integrated circuit board capable of realizing communication control connection, so as to realize the communication control connection between the devices in the first cylinder 1 and the second cylinder 2. With such a setting, the present utility model provides a technical solution for effectively isolating the control part and the heating part during the aging test fixture detection process. The present utility model provides the first cylinder 1 and the second cylinder 2 to effectively isolate the control part and the heating part during the aging test fixture detection process, so that the controller 11 and / or the power supply 12 are as little affected as possible by the heating temperature of the aging test fixture 3, and the reliability and safety of the aging test fixture detection are improved. It should be noted that the functions of the communicative connection between the controller 11 and the aging test fixture 3 include but are not limited to heating power control, data acquisition, temperature calibration, etc., which will not be elaborated here. The functional base plate 10 passes through the partition 20, so that not only can communication control connection be realized, but also the control part and the heating part of the aging test fixture detection container can be separated by the partition 20, so that the control part is as little affected by the temperature of the heating part as possible, and the reliability and safety of the aging test fixture detection container are enhanced.
[0035] It should be noted that in order to make the heat in the second cylinder 2 as little transferred to the first cylinder 1 as possible, heat insulation measures should be taken. In an exemplary embodiment, a heat insulation layer 21 is provided on the functional base plate 10 located in the second cylinder 2, but it should be noted that the heat insulation layer 21 does not cover the mounting portions 23, so as to prevent hindering the detachable installation of the aging fixture 3 on the mounting portions 23.
[0036] Similarly, in order to further insulate heat, the inner wall of the second cylinder block 2 should also be provided with the heat insulation layer 21. It should be understood that in order to prevent mechanical extrusion of the device caused by thermal expansion and contraction, the heat insulation layer 21 can be an elastic structure, so as to effectively protect the control part of the aging test fixture detection container while insulating heat. With such a setting, the present utility model further obtains the following advantages:
[0037] (1) In some tests, the aging test fixture 3 needs to be heated to a relatively high temperature to verify some parameter indicators. During this process, only the second cylinder block 2 has a relatively large temperature rise, and the temperature in the area of the functional bottom plate 10 is relatively constant, reducing the measurement error caused by temperature drift;
[0038] (2) Compared with a relatively airtight cavity, it isolates the interference caused by external environmental fluctuations and improves the reliability of the measurement results of temperature-related parameter indicators;
[0039] (3) The heat insulation layer 21 prevents the chassis from having a relatively large temperature rise and avoids scalding of the operator when contacting the outer wall of the chassis;
[0040] (4) The elastic structure of the heat insulation layer 21 can protect the functional board, sensors, etc.
[0041] It should be noted that a temperature sensor can also be included. The temperature sensor is arranged in the second cylinder block 2. The temperature sensor is used to collect the temperature signal of the heating module, and the temperature sensor is communicatively connected to the controller 11.
[0042] Please continue to refer to Figures 1 to 3 , further, the installation part 23 includes an adapter 22. The adapter 22 is used for the aging test fixture 3 to be detachably installed on the adapter 22. The function of the adapter 22 is to be able to adapt to different specifications of the aging test fixture 3, so that the aging test fixture detection container can be adapted to more specifications of the aging test fixture 3. It should be understood that the adapter 22 should be detachably connected to the installation part. In an exemplary embodiment, only the adapter 22 and some status indicators are exposed on the functional bottom plate 10, and except for some probes of other sensors, they are basically below the heat insulation layer 21.
[0043] Please refer to Figure 4 , Figure 4 is the front view of the aging test fixture detection container provided by an embodiment of the present utility model. As Figure 4As shown, it further includes an indicator light 25, and the indicator light 25 can display corresponding light signals according to the temperature of the aging test fixture 3. The indicator light 25 is mainly used to guide the operator to identify the working state of the aging test fixture for detecting the container. Especially when the temperature of the aging test fixture for detecting the container is too high, it reminds the operator to wait for the temperature to drop to an appropriate temperature before touching the surface and inside of the aging test fixture for detecting the container, further preventing scalding. The indicator light 25 can also integrate the control logic of the communication connection and display different light signals (such as different colors and blinking frequencies) according to the communication connection state, so as to guide the operator to understand the current working state of the aging test fixture for detecting the container. In an exemplary embodiment, there are four indicator lights 25 on the front panel for indicating the system state, and fixing screws are installed.
[0044] Please refer to Figure 5 , Figure 5 which is a side view of the aging test fixture for detecting the container provided by an embodiment of the present invention. As Figure 5 shown, heat dissipation holes are provided on the surface of the first cylinder body 1 and / or the second cylinder body 2, and a radiator 24 is provided on the heat dissipation holes. In an exemplary embodiment, the radiator 24 can be a cooling fan, but is not limited thereto. The control connection between the controller 11 and the cooling fan can also be established, so as to comprehensively adjust the heating power and the heat dissipation power, so that the temperature of the aging test fixture 3 is controlled within a preset range. In an exemplary embodiment, 3 fans are placed at the lower left of the second cavity 2, which are air inlets; 3 fans at the upper right are air outlets. The first cavity 1 is a closed cavity, and there are two fan air holes on each of the left and right sides.
[0045] Preferably, the second cylinder body 2 is provided with an opening and closing door (not shown in the figure). The operator can install and disassemble the aging test fixture 3 by opening and closing the opening and closing door.
