[0021] Figure 1 It is a schematic diagram of the structure of the power supply insulation shell of the comprehensive tester in the embodiment of the present disclosure. Implementation

[0022] The present disclosure is described below based on embodiments, but it is worth noting that the present disclosure is not limited to these embodiments. In the detailed description of the present disclosure below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present disclosure.

[0023] In addition, those skilled in the art should understand that the drawings are provided only to illustrate the purpose, features and advantages of the present disclosure, and the drawings are not actually drawn to scale. At the same time, unless the context clearly requires, the words "include", "comprise" and the like in the entire specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, "including but not limited to" meaning.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below based on the accompanying drawings and examples.

[0025] Figure 1 Schematic diagram of the structure of the power supply insulation shell of the comprehensive tester of the embodiment of the present disclosure. Figure 1 As shown in the figure mark, the power supply insulation shell of the comprehensive tester described in this embodiment includes a shell, which is composed of a front panel 3, a rear panel 14, a left panel 6, a right panel 11, an upper panel 7 and a lower panel 16. These panels are assembled into a rectangular shell by front fixing bolts 2 and rear fixing bolts 15.

[0026] like Figure 1 As shown, in the shell, a first insulation layer 4, a second insulation layer 5, a third insulation layer 12 and a fourth insulation layer 13 are arranged; these insulation layers are fixed in the shell by an intermediate bolt 8; wherein the second insulation layer 5 is provided with a comprehensive tester embedded structure, the third insulation layer 12 is provided with a charging module and a voltage stabilizing module embedded structure, the first insulation layer 4 serves as an insulation cover plate of the second insulation layer 5, the fourth insulation layer 13 serves as an insulation cover plate of the third insulation layer 12, the comprehensive tester embedded structure, the charging module and the voltage stabilizing module embedded structure constitute the insulation cavity of the comprehensive tester 18, the charging module 10 and the voltage stabilizing module 17.

[0027] Of course, before the low-temperature test is needed, the comprehensive tester is placed in the embedded structure of the second insulation layer 5, the charging module 10 and the voltage stabilizing module 17 are respectively placed in the embedded structure of the third insulation layer 12, the lithium battery of the comprehensive tester is connected to the voltage stabilizing module 17, and the voltage stabilizing module 17 is connected to the charging module 10. The voltage stabilizing module 17 stabilizes the output voltage of the charging module 10 to the working voltage of the lithium battery; after the comprehensive tester, the charging module 10 and the voltage stabilizing module 17 are placed in the power supply insulation shell of the present invention, the insulation layers and the various panels that make up the shell are assembled together by connecting bolts and the shell can be put into use.

[0028] Preferably, a button 1 is arranged on the front panel 3 , and a circular hole corresponding to the button 1 is arranged on the first thermal insulation layer 4 . The arrangement of the button 1 corresponds to the control button of the comprehensive tester 18 .

[0029] Preferably, a heating patch 9 or other heating components with the same function as the heating patch is pasted between the comprehensive tester 18 and the power supply module 10. The purpose is to provide a heat source, extend the insulation time of the comprehensive tester and the power supply module 10, and ensure the working time in a low-temperature environment.

[0030] In summary, the power supply insulation shell of the comprehensive tester disclosed in the utility model is composed of a power supply unit and a heat preservation unit; wherein the power supply unit has the functions of charging and supplying power and voltage stabilization, and solves the problem of battery capacity reduction of the battery of the comprehensive tester in a low temperature environment through the function of charging and supplying power; the output voltage is stabilized to 4V±0.2V through the voltage stabilization function, and the output voltage fluctuation is prevented from affecting the working state of the comprehensive tester, so as to ensure the accuracy of the test results of the comprehensive tester. The heat preservation unit has heating function and heat preservation function, and ensures that the temperature inside the heat preservation shell is maintained at 30℃~45℃ and the heating time is 4 hours to 6 hours by controlling the heat generation and heating time, so as to provide continuous heat to the comprehensive tester to avoid low temperature power attenuation, thereby ensuring the use time rate of the comprehensive tester in winter.

[0031] Specifically, the power supply unit is composed of a power supply module 10 and a voltage stabilizing module 17. The power supply module 10 replaces the original battery of the comprehensive tester and has the function of charging and supplying power at the same time. Since there is no charging power supply at the test site, when the battery capacity is insufficient, a mobile power supply is directly used to charge the power supply module 10, or the power supply module 10 directly uses a charging device similar to a mobile phone power bank, and then the lithium battery of the comprehensive tester is powered by the power supply module 10. The voltage stabilizing module 17 stabilizes the output voltage of the power supply module 10 to 4V±0.2V to meet the voltage requirements of the comprehensive tester and prevent the fluctuation of the output voltage from affecting the normal operation of the comprehensive tester.

[0032] The insulation unit insulates and fixes the comprehensive tester 18, the heating patch 9, the power supply module 10 and the voltage stabilizing module 17 through each insulation layer, and isolates the internal and external temperatures of the insulation layer to prevent the comprehensive tester 18 and the power supply module 10 from being used in a low temperature environment. The heating patch 9 adopts a chemical heating method, and the size of the holes of the non-woven fabric wrapped around the heating material can be used to control the amount of contact between the heating material and oxygen, thereby controlling the amount and time of heat generation. The front panel 3 of the shell is equipped with a transparent window, and the transparent window is made of transparent hard material. The design of the transparent window is convenient for the operator to observe the test results on the display screen of the comprehensive tester. The hardness of the material can realize the mutual cooperation of the fixing bolts and the fixing studs to fix the insulation layer. The button 1 is fixed on the front panel 3, and the corresponding position of the first insulation layer 1 is configured as a circular hole, so that the control button of the comprehensive tester can be controlled by pressing the button 1.

[0033] The above-described embodiments are only embodiments of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the present disclosure. It should be noted that, for a person of ordinary skill in the art, without departing from the concept of the present disclosure, several variations, equivalent substitutions, improvements, etc. may be made, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to the attached claims.
