Through insulation testing, insulation faults can be detected and repaired in a timely manner, ensuring the safe operation of electrical equipment and effectively preventing electrical fires and electric shock accidents.

[0003] Existing insulation testing methods mostly employ insulation testers, which are connected to the test piece. However, this approach is cumbersome, prone to errors, and poses safety hazards when testing insulation at different locations on the test piece. Utility Model Content

Detailed Implementation

[0025] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0027] Currently, insulation testing requires two people: one to test and the other to record. Furthermore, each insulation test requires repeated plugging and unplugging, making the process cumbersome. For example, when testing the controller with an insulation tester, the pins of the controller's connector are close together, while the tester's probes are of a certain length. Connecting the probes to the pins poses a risk of short-circuiting the connector pins and burning out the controller.

[0028] In view of this, this application provides an insulation test connection device that connects between the test piece and the insulation tester. It can connect multiple test points of the test piece to the test piece terminals and connect the probes of the insulation tester to the tester terminals. The connection between the test points and the probes is controlled by a switching assembly between the test piece terminals and the tester terminals, which simplifies the operation process and improves operational safety.

[0029] Figure 1 This is a front view of the insulation testing connection device provided in an embodiment of this application; Figure 2 Left view of the insulation test connection device provided in the embodiment of this application; Figure 3 for Figure 1 Internal structural perspective view; Figure 4 for Figure 2 Internal structural perspective view; Figure 5 An electrical schematic diagram of an insulation test connection device provided in an embodiment of this application.

[0030] like Figures 1 to 5As shown, some embodiments of this application provide an insulation testing connection device, including a housing 100, a switch assembly 200, a control assembly 300, and a power supply assembly 400. The housing 100 includes a wall portion 101 and a first chamber 102 and a second chamber 103 formed by the wall portion 101. The first chamber 102 and the second chamber 103 are stacked along a first direction X. The wall portion 101 includes a test piece terminal 110 and a test instrument terminal 120. The switch assembly 200 is placed in the second chamber 103 and connected between the test piece terminal 110 and the test instrument terminal 120 for controlling the on / off state of the test piece terminal 110 and the test instrument terminal 120. The control assembly 300 is placed in the first chamber 102 and connected to the switch assembly 200 for controlling the on / off state of the switch assembly 200. The power supply assembly 400 is placed in the first chamber 102 and connected to the control assembly 300 and the switch assembly 200 respectively for supplying power.

[0031] The box 100 can be in the form of simple shapes such as cuboids, cylinders, and prisms, or complex shapes composed of simple shapes. The material of the box 100 can be insulating materials such as plastic, ceramics, and glass, or conductive materials such as metal.

[0032] The wall portion 101 can enclose to form a first chamber 102 and a second chamber 103, or it can enclose to form other chambers. The first chamber 102 and the second chamber 103 can be connected or independent. The volumes of the first chamber 102 and the second chamber 103 can be the same or different, and their shapes can be the same or different. The first direction X can be the height, width, or length direction of the housing 100. In one example, the first direction X is the height direction of the housing 100, and the first chamber 102 and the second chamber 103 are arranged vertically.

[0033] By way of example, the wall portion 101 includes a plurality of sidewalls, and the test piece terminal 110 and the test instrument terminal 120 are mounted on at least one sidewall. The test piece terminal 110 and the test instrument terminal 120 are fixedly mounted on the sidewall or detachably mounted on the sidewall.

[0034] In one example, terminal 110 of the test device is used to connect to the test device; terminal 120 of the tester is used to connect to the insulation tester.

[0035] The switch assembly 200 is an electrical component with a switching function. Exemplarily, the switch assembly 200 may include one or more switching elements, and exemplaryly, the switch assembly 200 may include one or more of a mechanical switch, a solid-state switch, or a magnetic switch. The mechanical switch may be a push-button switch, a rocker switch, a toggle switch, a slide switch, etc. The solid-state switch may include a transistor, a thyristor, etc. The magnetic switch may include a contactor 201, a Hall effect switch, etc.

[0036] The switch assembly 200 can be fixedly installed in the second chamber 103 or detachably installed in the second chamber 103. The test device terminal 110 and the test instrument terminal 120 are connected through the switch assembly 200. When the switch assembly 200 is closed, the test device terminal 110 and the test instrument terminal 120 are conductive. When the switch assembly 200 is closed, the test device terminal 110 and the test instrument terminal 120 are disconnected.

[0037] In one example, terminal 110 of the device under test is connected to the device under test; terminal 120 of the tester is connected to the insulation tester. When the switch assembly 200 is closed, the insulation tester checks the insulation of the device under test. When the switch assembly 200 is closed, the insulation tester does not work.

[0038] Control component 300 is an electrical component that provides signals to the switching component 200. Control component 300 may include one or more electrical components. Exemplarily, control component 300 may include one or more of a relay 301, a programmable logic controller (PLC), a sensor, a timer, and a computer.

[0039] The control component 300 can be fixedly installed within the first chamber 102 or detachably installed within the first chamber 102. The control component 300 can be wired or communicatively connected to the switch component 200. The control component 300 can send a first control signal to the switch component 200, causing the switch component 200 to close. The control component 300 can send a second control signal to the switch component 200, causing the switch component 200 to close. The first and second control signals can be electrical signals or manual signals, etc.

[0040] The power supply assembly 400 may include one or more of a power supply and a switching power supply 401. For example, the power supply assembly 400 may provide direct current or alternating current. The power supply assembly 400 supplies power to the control assembly 300 and the switching assembly 200. The power supply assembly 400 may be connected to the control assembly 300 and the switching assembly 200 via wire connection or contact power supply, etc.

[0041] The power supply assembly 400 and control assembly 300 are for low-voltage circuits, while the switch assembly 200 is for high-voltage circuits. Separating the high-voltage and low-voltage circuits reduces interference from the high-voltage circuits to the low-voltage circuits.

[0042] By controlling the on / off state of the switch assembly 200 through the control component 300, the connection between the test device terminal 110 and the tester terminal 120 is controlled, enabling selective testing between the test device and the tester without repeated plugging and unplugging. The connection between the test device and the tester is achieved by opening and closing the switch assembly 200, resulting in higher connection stability between the test devices. Furthermore, the layered arrangement of the switch assembly 200 and the control component 300 reduces interference and improves test stability and accuracy.

[0043] Furthermore, in some embodiments of this application, the test piece terminal 110 includes a power terminal 111 and a motor terminal 112 spaced apart along the second direction Y, and both the power terminal 111 and the motor terminal 112 are disposed opposite to the second chamber 103.

[0044] In one example, the first direction X is the height direction of the box 100, and the second direction Y is the width direction of the box 100.

[0045] The test piece terminal 110 can be a plug-in terminal, a barrier terminal, a spring terminal, a rail terminal, etc.

[0046] In one example, power terminal 111 includes a P2 barrier terminal, and motor terminal 112 includes a P3 barrier terminal. Power terminal 111 can be connected to the DC portion of the device under test, and motor terminal 112 can be connected to the AC portion of the device under test.

[0047] The power terminal 111 and the motor terminal 112 can be connected to the device under test simultaneously or individually. For example, the switch assembly 200 includes multiple switches, with at least two switches connected to the power terminal 111 and the motor terminal 112.

[0048] Since the wiring between the test piece and the test piece terminal 110 occupies a large space, in order to improve the ease of connection between the test piece and the test piece terminal 110, the power terminal 111 and the motor terminal 112 are arranged alternately. In order to reduce the size of the housing 100, the power terminal 111 and the motor terminal 112 extend along the second direction Y. The switch assembly 200 is placed in the second chamber 103. In order to shorten the wiring length and facilitate wiring, the power terminal 111 and the motor terminal 112 are both arranged opposite to the second chamber 103.

[0049] Continue to refer to Figures 3 to 5As shown, in one specific embodiment of this application, the switch assembly 200 includes a plurality of contactors 201, which are evenly distributed in the second chamber 103 and connected to the wall portion 101.

[0050] For example, the switch assembly 200 may include multiple contactors 201, such as 2, 3, 5, or 6. Each contactor 201 is connected to the power supply assembly 400. In one example, multiple contactors 201 are connected to a control assembly 300, which individually controls the on / off state of each of the multiple contactors 201.

[0051] Multiple contactors 201 may be discretely distributed within the second chamber 103 or arranged in rows and columns within the second chamber 103. The multiple contactors 201 may be located along the height of the first direction X within the second chamber 103 or may be different. Exemplarily, the multiple contactors 201 may be connected to one or more sidewalls of the wall portion 101. The contactors 201 may be detachably connected, fixedly connected, or limit-connected to the sidewalls.

[0052] The even distribution of multiple contactors 201 facilitates the wiring of the power supply component 400 and control component 300 connected to the contactors 201, making connection and maintenance easier.

[0053] Figure 6 This is a top view of an insulation testing connection device according to an embodiment of this application, wherein perspective is used to illustrate the various structures.

[0054] like Figure 6 As shown, in some optional embodiments of this application, a plurality of contactors 201 are arranged in rows at intervals along a third direction, with the contactors 201 in adjacent rows being arranged alternately.

[0055] There is a gap between adjacent rows, and the gap distance can be the same or different. The number of contactors 201 in each row can be the same or different. In one example, the switch assembly 200 includes 5 contactors 201 and is divided into two rows along the second direction Y, one row with 3 contactors 201 and the other row with 2 contactors 201.

[0056] Each row may have one or more contactors 201. For example, when each row has multiple contactors 201, the multiple contactors 201 are spaced apart, and the spacing may be the same or different.

[0057] In the projection plane along the third direction Z, the contactors 201 between adjacent rows do not overlap, thus realizing the alternating setting of the contactors 201 between adjacent rows.

[0058] Specifically, in the embodiments of this application, the test device terminal 110 includes a plurality of first contacts, and the test instrument terminal 120 includes a plurality of second contacts. The first contacts, the second contacts, and the contactor 201 are connected in a one-to-one correspondence.

[0059] The first contact can be a male contact, such as a pin, or a female contact, such as a socket. The male contact can be a rigid part, and its shape can be cylindrical, square, or flat, usually made of brass, phosphor bronze, etc. Examples include round pins, square pins, and inserts. The female contact, i.e., the socket, relies on an elastic structure to undergo elastic deformation when inserted with a pin, generating elastic force to form a tight contact with the male contact, thus completing the connection. There are many types of socket structures, including cylindrical, tuning fork, cantilever beam, folded, box-shaped, and hyperboloid spring sockets. The second contact works similarly.

[0060] The number of first contacts, second contacts, and contactors 201 are equal; that is, one first contact, one second contact, and one contactor 201 are connected. Each first contact is connected to one test point of the test piece.

[0061] Continue to refer to Figures 3 to 5 In some embodiments of this application, the control component 300 includes an adapter 303, a digital output module 302, and a relay 301. The adapter 303 is installed through the wall portion 101. The digital output module 302 is connected to the relay 301 and the adapter 303. Both the relay 301 and the digital output module 302 are connected to the power supply component 400. Along the second direction Y, the relay 301 is positioned between the digital output module 302 and the power supply component 400.

[0062] The adapter 303 is used for connection to the host computer 310 and is connected to the digital output module 302. For example, the adapter 303 may include a D-Sub type electronic interface, a USB adapter 303, an RS232 adapter terminal, etc., such as a DB9 female connector.

[0063] The Digital Output Module (DO module) 302 converts the digital signals from the host computer 310 into actual output signals to drive various actuators or devices. For example, the Digital Output Module 302 may have multiple output channels, each of which can independently control a relay 301.

[0064] Relay 301 is used in the main control switch assembly 200 and the protection switch assembly 200. Relay 301 can be an electromagnetic relay 301, a solid-state relay 301, etc.

[0065] For example, the host computer 310 sends the digital signal to the digital output module 302 through the adapter 303, which converts it into a control signal to control the switch of the relay 301.

[0066] When the power supply assembly 400 is working, some interference will be generated due to the switching of internal components. In order to reduce the impact of this interference on the communication between the adapter 303 and the digital output module 302, the relay 301 is placed between the digital output module 302 and the power supply assembly 400, so that the power supply assembly 400 and the digital output module 302 are far apart, thereby reducing the impact on the communication of the digital output module 302.

[0067] Continue to refer to Figure 6 In one embodiment of this application, the wall portion 101 includes a first sidewall 130 along the second direction Y. The first sidewall 130 is located on the side of the digital output module 302 facing away from the relay 301. The adapter 303 is installed on the first sidewall 130 and is opposite to the first chamber 102.

[0068] The digital output module 302 is positioned close to the first side wall 130, and the adapter 303 is mounted on the first side wall 130 and positioned opposite to the first chamber 102 where the digital output module 302 is located, so that the communication connection between the digital output module 302 and the adapter 303 is shorter and the communication quality is improved.

[0069] In other embodiments of this application, the wall portion 101 further includes two second sidewalls 140 opposite each other in a third direction Z. The two second sidewalls 140 are located on both sides of the digital output module 302, and the adapter 303 can be installed on the second sidewalls 140 and opposite to the first chamber 102.

[0070] Continue to refer to Figure 1 In another embodiment of this application, the wall portion 101 further includes two third sidewalls 150 disposed opposite to each other along the first direction X, and a handle 151 may be installed on one of the third sidewalls 150.

[0071] Continue to refer to Figures 1 to 4 In some embodiments of this application, the power supply assembly 400 includes a power plug 402 and a switching power supply 401, the switching power supply 401 is connected to the power plug 402, the relay 301 is placed between the digital output module 302 and the switching power supply 401, and the power plug 402 is opposite to the first chamber 102.

[0072] The power plug 402 can be used for power connection, and the power plug 402 can be a three-prong or two-prong plug. Exemplarily, the power plug 402 is installed through the wall portion 101.

[0073] Switching power supply 401 refers to a power conversion device. Switching power supply 401 controls and stabilizes the output voltage by rapidly switching electronic components such as transistors.

[0074] In other words, the insulation test connection device can be powered by its own power supply or by an external power supply.

[0075] The switching power supply 401 is located away from the digital output module 302 to reduce the impact of the switching electronic components in the switching power supply 401 on communication.

[0076] Specifically, in the embodiments of this application, the wall portion 101 includes a plurality of sidewalls, the tester terminal 120 and the test piece terminal 110 are respectively located on two sidewalls, and the tester terminal 120 is opposite to the second chamber 103.

[0077] Exemplarily, the tester terminal 120 and the test device terminal 110 are located on two adjacent or opposite sidewalls. In one example, the tester terminal 120 is located on a first sidewall 130 or a second sidewall 140. The test device terminal 110 is located on a fourth sidewall 131 opposite to the first sidewall 130.

[0078] The tester terminal 120 and the test piece terminal 110 are located on two different side walls to facilitate the connection between the insulation tester and the test piece and avoid wiring interference.

[0079] This application also provides an insulation testing system, including an insulation tester and an insulation testing connection device as described above, wherein the insulation tester is connected to the tester terminal block 120.

[0080] like Figures 1 to 6 As shown in the embodiment of this application, an insulation testing device is also provided. The insulation testing device can realize automatic testing of high voltage insulation through 485 communication and digital output module 302, 12V 6-channel relay 301, and contactor 201; and realize automatic uploading of test results and formation of test records through 232 communication.

[0081] Specifically, the host computer 310 inputs corresponding commands to the digital output module 302 via 485 communication. The digital output module 302 is connected to the 12V 6-channel relay 301, controlling the energization of the 12V 6-channel relay 301, thereby controlling the energization of the contactor 201. When it is necessary to test the first position of the controller, one contactor 201 is energized, and one channel of the switching assembly 200 is turned on, allowing the first position of the controller to be tested.

[0082] The 12V+ of the coil of contactor 201 is connected to the V+ of the 150W switching power supply 401, and the 12V- of the coil of contactor 201 is connected to the 12V 6-channel relay 301 module. Through communication control, the 12V- is connected to the V- of the 150W switching power supply 401, thereby energizing contactor 201.

[0083] The five contactors 201 are connected to each other via fence-type terminals, power connection terminals, and motor connection terminals.

[0084] The insulation tester and the host computer 310 are connected via RS-232 communication.

[0085] The insulation testing device has a handle 151 on the top panel; a DB9 female connector on the front panel for communication with the host computer 310; a P2 and a P3 fence-type terminal block on the rear panel for connecting to the test piece. When testing different product models, only the fence-type terminal blocks need to be replaced; the insulation testing device itself does not need to be replaced. A P5 fence-type terminal block on the left side panel is used to connect to the insulation tester; and a 220V power plug 402 on the right side panel powers the entire insulation testing device.

[0086] During operation, connect the motor connection terminal and power connection terminal of the test component according to the markings, and connect the ground wire of the test component. Turn on the host computer 310 and the insulation tester. Perform high-voltage insulation testing on the controller according to the test sequence. The insulation testing device is not affected by the operator's skill level, is convenient and quick, reduces operator time, lowers testing difficulty, effectively improves testing efficiency, and avoids product burnout due to operational errors.

[0087] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
