[0092] Figure 1 It is a schematic structural diagram of an experimental device for a contactor provided for the embodiments of the present application.

[0093] Please refer to Figure 1As shown in the figure, the experimental device 100 of the contactor provided by the embodiment of the present application includes a base 10, a test chamber 20, a temperature adjustment component 30, a humidity adjustment component 40, a lifting component 110, an experimental box 120, a detection component 130, a moving component 140, a first support plate 150, and a controller 50.

[0094] Among them, the experimental box 120 is used to place the contactor.

[0095] The base 10 is used to fix and support multiple experimental devices. For example, the experimental device includes the test chamber 20 and the like.

[0096] In the actual application process, the base 10 can be set as a rectangular plate, and feet can be provided at the bottom of the base 10. Among them, the number of feet can be determined according to the support direction of the base 10, and the embodiment of the present application does not limit this.

[0097] The test chamber 20, the temperature adjustment component 30, and the humidity adjustment component 40 are arranged on the base 10.

[0098] The test chamber 20 is used to detect the performance of the contactor. There is a relatively large cavity inside the test chamber 20 to place other experimental devices.

[0099] The humidity adjustment component 40 is used to adjust the humidity value inside the test chamber 20. In the embodiment of the present application, the humidity inside the test chamber 20 can be adjusted by clean water.

[0100] The temperature adjustment component 30 is used to adjust the temperature value inside the test chamber 20. In the embodiment of the present application, the temperature inside the test chamber 20 can be adjusted by air.

[0101] The controller 50 is used to control the lifting component 110 to move in the vertical direction and control the moving component 140 to move in the horizontal direction.

[0102] Optionally, the connection manner between the controller 50 and the lifting component 110 and the moving component 140 can be a wired connection (for example, communication cables, etc.), or a wireless connection. The embodiment of the present application does not limit this.

[0103] In the actual application process, a Programmable Logic Controller (PLC) can be set inside the controller 50 to control the experimental devices connected to the controller 50. The user can issue control instructions by clicking or inputting operations on the visual operation interface, or by calling the operation interface through other application programs. After receiving the control instructions, the controller 50 controls the relevant experimental devices.

[0104] For the convenience of understanding, the following will be combined with Figure 2, the structure of an experimental device for a contactor provided by an embodiment of the present application will be further described.

[0105] Figure 2 For the structural schematic diagram of another experimental device for a contactor provided by an embodiment of the present application, please refer to Figure 2 , which includes a base 10, a test chamber 20, a temperature regulating component 30, a humidity regulating component 40, and a controller 50. Among them, the controller 50 is arranged outside the test chamber 20, and relevant detection parameters can be read through a visual operation interface.

[0106] In an embodiment of the present application, the visual operation interface may include a temperature setting module, a humidity setting module, a lifting component movement module, a detection component movement module, etc. The user can input the target temperature and humidity values at the relevant modules through a touch screen or a knob, and the current temperature and humidity values can be displayed through the visual operation interface. The user can also click the corresponding button to move the lifting component and the detection component.

[0107] For example, after the user clicks "Lifting component moves up" on the operation interface, the controller 50 controls the lifting component 110 to move upward according to the control instruction.

[0108] The lifting component 110 is arranged at the bottom of the test chamber 20, and the experimental box 120 is arranged on the lifting component 110. The lifting component 110 is used to drive the experimental box 120 to move in the vertical direction.

[0109] In an embodiment of the present application, the moving range of the lifting component 110 can be set through the operation interface, including the rising and falling heights. For example, the user can click "Lifting component moves up" on the operation interface and input "Rising height 2 mm", then the controller 50 moves the lifting component 110 upward by 2 mm according to the above control instruction.

[0110] The first support plate 150 is arranged inside the test chamber 20, the moving component 140 is arranged below the first support plate 150, and the detection component 130 is arranged below the moving component 140. The moving component 140 is used to drive the detection component 130 to move in the horizontal direction.

[0111] The first support plate 150 is used to support the internal space of the test chamber 20. The shape of the first support plate 150 can be a rectangular plate, and its size is the same as the size of the cross-section of the test chamber 20.

[0112] In an embodiment of the present application, the first support plate 150 can be arranged at a position above the middle inside the test chamber 20 according to the moving range of the lifting component 110 and the thickness of the experimental box 120, so as to facilitate the vertical movement of the lifting component 110 and the experimental box 120.

[0113] The moving component 140 can be fixed to the bottom of the first support plate 150 by setting a plurality of fixed brackets.

[0114] The detection component 130 is used to detect the contactor in the experimental box 120.

[0115] In the actual application process, the position and angle of the detection component 130 can be adjusted according to the actual situation. A pressure sensor can also be set inside the detection component 130. The pressure sensor is used to monitor the pressure value between the detection component 130 and the contactor to better detect the performance of the contactor.

[0116] The temperature adjustment component 30 and the humidity adjustment component 40 are respectively connected to the experimental box 120. The controller 50 is used to control the temperature adjustment component 30 to adjust the ambient temperature of the experimental box 120 and control the humidity adjustment component 40 to adjust the ambient humidity of the experimental box 120.

[0117] A temperature sensor and a humidity sensor can be set in the experimental box 120. Among them, the temperature sensor is used to monitor the temperature value inside the experimental box 120, and the humidity sensor is used to monitor the humidity value inside the experimental box 120.

[0118] Optionally, the connection manner between the controller 50 and the temperature adjustment component 30 and the humidity adjustment component 40 can be wired connection or wireless connection, and the embodiments of the present application do not make any limitation.

[0119] The ambient temperature and ambient humidity of the experimental box 120 can be controlled in the following way: The user can preset the required temperature value and humidity value on the operation interface; the controller 50 compares the temperature value collected by the high-precision temperature sensor received with the preset temperature value and compares the humidity value collected by the high-precision humidity sensor received with the preset humidity value, and displays the above data on the operation interface; the temperature adjustment component 30 is controlled according to the temperature difference to adjust the ambient temperature of the experimental box 120, and the humidity adjustment component 40 is controlled according to the humidity difference to adjust the ambient humidity of the experimental box 120.

[0120] It should be noted that the execution order of the contactor detection of the test chamber 20, the temperature adjustment of the temperature adjustment component 30, and the humidity adjustment of the humidity adjustment component can be parallel execution or sequential execution, and the embodiments of the present application do not make any limitation in this regard.

[0121] Next, the working process of the experimental device of the contactor will be described:

[0122] When performing the performance detection of the contactor, the contactor needs to be pre-placed in the experimental box 120. The controller 50 first starts the temperature control component 30 and the humidity control component 40 to adjust the environmental temperature and humidity in the experimental box 120 respectively to reach the set values. Subsequently, the controller 50 controls the lifting component 110 to move in the vertical direction to adjust the experimental box 120 to the required height in the test chamber 20; at the same time, the controller 50 drives the moving component 140 under the first support plate 150 to move horizontally, so that the detection component 130 accurately moves to the corresponding position above the experimental box 120. When the temperature and humidity conditions in the experimental box 120 are stable and the detection component 130 is in place, the detection component 130 performs real-time detection on the performance parameters (such as resistance, etc.) of the contactor. During the detection process, the controller 50 continuously maintains the stability of the temperature and humidity in the experimental box 120 through the temperature control component 30 and the humidity control component 40. After the detection is completed, the controller 50 analyzes the detection data of the detection component 130 and displays the analysis result on the operation interface, completing the performance detection of the contactor in different temperature and humidity environments.

[0123] In the embodiment of the present application, when performing the performance detection of the contactor, the coordinated control of the lifting component, the moving component, the temperature control component, and the humidity control component can be realized through the controller. Specifically, the controller synchronously drives the lifting component to drive the experimental box to move in the vertical direction to adjust the detection height of the contactor, and at the same time controls the moving component to drive the detection component to move horizontally to cover the multi-directional detection area of the contactor. The temperature control component and the humidity control component respectively independently adjust the temperature and humidity parameters in the experimental box to simulate different environmental working conditions. In the above process, the detection component can comprehensively detect the contactor in a dynamically changing temperature and humidity environment and multi-dimensional spatial positions, eliminating the manual adjustment error and environmental interference, and improving the reliability of the performance detection of the contactor.

[0124] Based on any one of the above embodiments, below, in combination with Figure 3 , the structure of the experimental device of the contactor will be described.

[0125] Figure 3 FIG. 12 is a schematic structural diagram of another experimental device of the contactor provided by the embodiment of the present application. The lifting component 110 includes a second support plate 111, a telescopic cylinder 112, and an inclined rod 113.

[0126] The second support plate 111 is arranged at the bottom of the test chamber 20.

[0127] The second support plate 111 is used to fix and support the lifting component 110. The second support plate 111 can be set as a rectangular plate, and its size is slightly larger than the size of the inclined rod 113.

[0128] One end of the inclined rod 113 is fixed on the second support plate 111, and the experimental box 120 is arranged at the other end of the inclined rod 113.

[0129] One end of the telescopic cylinder 112 is fixed on the second support plate 111, and the other end of the telescopic cylinder 112 is connected to the inclined rod 113.

[0130] The controller 50 is further configured to control the telescopic cylinder 112 to expand and contract to drive the inclined rod 113 to rotate, so that the lifting assembly 110 moves in the vertical direction.

[0131] In the actual application process, a solenoid valve may be arranged in the telescopic cylinder 112. The solenoid valve is used to control the expansion and contraction of the telescopic cylinder 112, and the solenoid valve is connected to the controller 50. The controller 50 can send instructions to the solenoid valve of the telescopic cylinder 112 through an electrical signal or a communication protocol to control the extension or contraction action of the cylinder.

[0132] Optionally, when it is necessary to lift the lifting assembly 110, the controller 50 drives the telescopic cylinder 112 to extend, pushing the inclined rod 113 to rotate clockwise around its fulcrum (the connection with the telescopic cylinder 112) to convert it into a vertical upward displacement of the lifting assembly 110; when it is necessary to lower the lifting assembly 110, the controller 50 controls the telescopic cylinder 112 to contract, and the inclined rod 113 rotates counterclockwise, driving the lifting assembly 110 to smoothly descend in the vertical direction.

[0133] Among them, a position sensor may be arranged in the lifting assembly 110. The position sensor is used to collect the current height value of the lifting assembly 110. At the same time, the controller 50 can receive the data collected by the position sensor of the lifting assembly 110, so that the experimental box 120 can be accurately positioned to the target height.

[0134] The moving assembly 140 includes a motor 141, a rotating shaft 142, a threaded rod 143, and a guide rod 144.

[0135] The motor 141 is used to drive the rotating shaft 142 to start and stop. The motor 141 is arranged in the temperature control assembly 30.

[0136] One end of the rotating shaft 142 is connected to the motor 141, and the other end of the rotating shaft 142 is connected to the threaded rod 143. The threaded rod 143 and the guide rod 144 are respectively fixedly arranged below the first support plate 150, and the threaded rod 143 and the guide rod 144 are arranged in parallel.

[0137] The detection assembly 130 is arranged on the threaded rod 143 and the guide rod 144.

[0138] The controller 50 is further configured to control the motor 141 to work. The motor 141 is used to drive the rotating shaft 142 to rotate, so as to drive the threaded rod 143 to rotate, and further drive the detection assembly 130 to move in the horizontal direction.

[0139] The controller 50 can drive the rotating shaft 142 and the threaded rod 143 to rotate around the axis by controlling the start, stop and rotation speed of the motor 141.

[0140] The detection component 130 includes a moving seat 131 and a detection piece 132.

[0141] The moving seat 131 is used to drive the detection piece 132 to move.

[0142] The detection piece 132 is arranged below the moving seat 131. The detection piece 132 is used to perform a contact test on the contactor.

[0143] A contact adjustment device can be arranged in the detection component 130. The contact adjustment device is used to adjust the position and angle of the detection piece 132. Among them, the contact adjustment device is respectively connected to the moving seat 131 and the detection piece 132.

[0144] In the embodiment of the present application, the contact adjustment device can be a pointer turntable. The current position and angle information of the detection piece 132 can be determined by rotating the pointer turntable and according to the scale marks on the pointer turntable, so that the detection piece 132 is accurately aligned with the contactor.

[0145] The moving seat 131 is arranged on the moving component 140. The moving component 140 drives the moving seat 131 to move horizontally to drive the detection piece 132 to move horizontally.

[0146] In the embodiment of the present application, through the coordinated control of the controller on the motor, the lifting component and the moving component, the accurate adjustment of the detection position of the contactor is realized. Specifically, the controller drives the telescopic cylinder to expand and contract to drive the inclined rod to rotate and convert it into the vertical lifting of the experimental box. At the same time, the controller controls the motor to start. The motor drives the rotation of the rotating shaft and the threaded rod, so that the moving seat and the detection piece move horizontally along the guide rod. In the above process, the horizontal movement of the detection piece is completed through the threaded rod, the rotating shaft and the guide rod, and the vertical movement of the experimental box is completed through the inclined rod and the telescopic cylinder, so as to realize the full-coverage detection and accurate positioning of the spatial position of the contactor, and improve the reliability of the performance detection of the contactor.

[0177] Next, in combination with Figure 6 , through specific examples, the internal structure of the temperature control box will be further described.

[0178] Figure 6 The following is a schematic diagram of the internal structure of the temperature control box provided by the embodiment of the present application. Please refer to Figure 6 , which includes a temperature control box 31, a fan 33, a temperature control pipeline 34, a motor 141, and a rotating shaft 142.

Please refer to Figure 7 , the central area of the experimental box 120 is a placement groove 121, and an opening is provided on one side of the experimental box 120 to communicate with the second temperature control pipeline 342.

[0185] In the actual application process, a gas guiding device can be arranged in the hollow area, and the gas guiding device is evenly distributed inside the experimental box 120 so that the contactors in the placement groove 121 are in a constant temperature environment.

[0186] In the embodiment of the present application, through the coordinated adjustment of the humidity adjustment component and the temperature adjustment component, precise control of the temperature and humidity in the experimental box is achieved.
