Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a power grid intelligent fusion terminal testing device. Background Art

[0002] Grid intelligent converged terminals (also referred to as converged terminals or intelligent converged terminals) are essential components of smart distribution networks. Typically installed within distribution substations, these integrated, multifunctional, and intelligent edge devices differ from concentrators, feeder terminals, dedicated transformer terminals, and distribution transformer terminals primarily in that they are based on a unified hardware and software platform with powerful edge computing, data storage, communication, and data security capabilities, providing functional expansion and adaptability for specific use cases. The use of grid intelligent converged terminals enables comprehensive perception of distribution substation information, intelligent business processing, and precise execution of control commands. These terminals effectively support the development of digital, intelligent, and interactive distribution networks, and are crucial for building a safe, reliable, efficient, and green modern distribution network.

[0003] In existing applications, the main functions of smart grid convergence terminals include multi-type grid data collection, data edge computing and processing, grid protection and control, and network communication support. Furthermore, in different application scenarios, these terminals leverage their highly open and scalable platform functionality. This is achieved through the flexible integration of various expansion modules via reserved standard interfaces or slots to meet the differentiated needs of different application scenarios and substations. Data collection and perception capabilities typically require voltage data collection, current data collection, analog / switch data collection, energy metering data collection, and fault indication data collection. Communication capabilities typically include cellular mobile communications, carrier communications, serial communications, and short-range wireless communications. Control capabilities typically require adapting to the differentiated control signal needs and signal feedback of different actuators. Data processing and storage capabilities typically include processor expansion and storage module expansion. Data security requirements typically include adapting to different hardware and software encryption modules.

[0004] In specific applications, according to different needs in different usage scenarios, the actual data collection and perception capabilities, communication capabilities, control capabilities, data processing and storage capabilities, data security capabilities, etc. of the power grid intelligent fusion terminal are configured by selectively plugging functional modules into the power grid intelligent fusion terminal. This requires that the uniformly produced power grid intelligent fusion terminal has the ability to plug in and use various possible functional modules to expand and enrich its functions and performance. In order to ensure the performance reliability and product quality of the power grid intelligent fusion terminal, before the power grid intelligent fusion terminal leaves the factory, a method that can be used is based on a test device, and possible functional modules are used as standard modules on the test device. These standard modules are connected to the power grid intelligent fusion terminal to detect whether the power grid intelligent fusion terminal can adapt to various types of functional modules. Relevant technical solutions in the existing technology, such as the technical solution provided by patent application number: CN202221556861.4 (the name of the invention is: A portable substation intelligent fusion terminal functional module detection device).

[0005] However, when testing the smart grid fusion terminal, it is necessary to connect various standard modules, such as 4G modules, carrier modules, data acquisition expansion modules, etc. Given the need to connect the smart grid fusion terminal to the test device during testing, it is necessary to further optimize the test device to facilitate plugging and unplugging and reduce losses during the testing process. Utility Model Content

[0006] The purpose of the present utility model is to provide a power grid intelligent fusion terminal test device, which is used to optimize the test device as mentioned above, specifically to solve the loss problem of the standard module on the test device after multiple plugging and unplugging, and at the same time, facilitate the correct plugging of the pins.

[0007] The purpose of the utility model is mainly achieved through the following technical solutions: a power grid intelligent fusion terminal test device, including a device panel, the device panel is configured with an installation station for installing the fusion terminal, and also includes a plurality of standard modules for connecting to the expansion module interface on the fusion terminal, the standard modules are respectively configured with a third interface fixed on the device panel, the third interface serves as a lead wire interface of the standard module, the third interface is configured with a lead wire, and the lead wire is used to realize the electrical connection between the expansion module interface and the third interface;

[0008] The lead wire includes a cable, a pin socket arranged at the end of the cable, and a pin fixed on the pin socket, and the pin socket is made of transparent material.

[0009] In the above scheme, the device panel is used as the test panel of the test device, the installation station is the installation position on the device panel for installing the fusion terminal to be tested, and the standard module is a test module configured on the test device for connecting to the expansion module interface on the fusion terminal. Usually, the expansion module of the fusion terminal is simulated by the standard module. When the standard module test shows that the fusion terminal is well compatible with various expansion modules, it means that the fusion terminal can mount the relevant type of expansion module and realize the relevant functions of the expansion module. In a specific application environment, the user can selectively connect these expansion modules to the fusion terminal according to usage needs, so that the relevant expansion functions can be reliably realized by the fusion terminal.

[0010] The above is the basic principle and function of the power grid intelligent fusion terminal test device. This solution targets these standard modules, which usually need to be connected and separated from the expansion module interface on the fusion terminal through plugging and unplugging. During the repeated plugging and unplugging of the standard module, the connector position is easily damaged after multiple plugging and unplugging. At the same time, the connector position forms a pin group based on the pins. When the pin group is incorrectly connected to the pins of the relevant interface, possible situations may include test failure and damage to the standard module. A method is provided to indirectly connect the standard module and the expansion module interface based on a third interface and a lead wire, and based on the pin seat made of transparent material on the lead wire, a visual connection between the pin group and the pins is achieved, thereby solving the loss problem of the standard module on the test device after multiple plugging and unplugging, facilitating the correct plugging of the pins, and implementing a technical solution for checking the correct connection of the pins.

[0011] Specifically, when using this test device to test a converged terminal's expansion module, the standard module, acting as a simulated module for the expansion module or as an expansion module that can be directly mounted on the expansion module interface, is connected to the expansion module interface via a third interface and a lead wire. Unlike conventional converged terminal testing, where the standard module is directly connected to the expansion module interface, the third interface and lead wire are used to transfer the converged terminal and standard module. Therefore, connecting and disconnecting the converged terminal and standard module simply requires plugging and unplugging the lead wire from the expansion module interface. Consequently, when this test device is repeatedly used to test converged terminals, plugging and unplugging the standard module into the expansion module interface is replaced with plugging and unplugging the lead wire into the expansion module interface, transferring potential damage to the pins on the standard module interface to the pins on the lead wire. This solution eliminates the problem of the standard module obstructing the position of its pins and the expansion module interface, as occurs when the standard module is plugged into the converged terminal. This solution not only facilitates plugging and unplugging the standard module relative to the converged terminal, but also, if the lead wire becomes damaged due to repeated use, simply replacing the lead wire restores the test device's testing capabilities. In this solution, the pin holder on the lead wire is further configured to be a transparent structure, and the specific material can be, for example, acrylic material. In this way, when connecting the pin on the lead wire to the expansion module interface, the transparent property of the pin holder can be used to observe the relative position of the pin and the pin on the expansion module interface and determine the specific connection position of the pin on the pin. The property of the pin holder being a transparent material not only facilitates the rapid matching of the relative positions of the pin and the pin, but also, when the lead wire and the expansion module interface remain connected, it is also possible to check by observation whether the pin is correctly connected to the correct pin of the expansion module interface, thereby assisting in completing the correct insertion of the pin and verifying the correct insertion of the pin, and facilitating the rapid elimination of possible faults in the event of test failure.

[0012] As a person skilled in the art, in the existing fusion terminal expansion performance test, the standard module is an important module used to simulate the expansion module on the test device. In the existing technology, these standard modules need to be directly connected to the expansion module interface on the fusion terminal through the pins thereon. In this solution, the connection between the standard module and the fusion terminal is realized through the third interface and the lead wire. The actual improvement lies in changing the physical connection structure to realize the indirect connection between the standard module and the fusion terminal. The standard module needs to be used repeatedly, thereby reducing the number of plugging and unplugging times on the standard module interface during the test, thereby solving the problem that the standard module is easily damaged after repeated plugging and unplugging, resulting in increased test loss. Therefore, the improvement of the connection method between the standard module and the fusion terminal in this solution is only in the improvement of the physical structure, and does not involve computer programs and computer program improvements; and the pin holder is made of transparent material, which is also limited to the selection of lead wires or pin holder materials, and does not involve material improvements.

[0013] At the same time, as a person skilled in the art, connecting a standard module to the extension module interface to perform extension module compatibility testing on the fusion terminal is only part of the fusion terminal test. For example, the fusion terminal generally integrates basic data acquisition functions, data processing functions, communication functions, and control instruction output functions. If these functions are to be tested, when the signal test module used to test these integrated functions is wired to the relevant data interface on the fusion terminal, first, the signal test module does not need to be directly mounted on the data interface. Secondly, these wired connections usually do not need to use the serial port module based on multiple pins and pins used by the extension module interface, that is, the interface on the signal test module for establishing a wired connection is not easily damaged during repeated use. Therefore, it is easy to understand that the core idea of ​​the improvement of the test device in this scheme is to change the physical connection link connecting the standard module and the extension module interface.

[0014] A further technical solution of the power grid intelligent fusion terminal test device is:

[0015] It also includes a signal testing module, which is used to connect to the signal line interface of the converged terminal;

[0016] The standard modules are one or more of a current signal acquisition module, a voltage signal acquisition module, a power signal acquisition module, an analog / switch signal acquisition module, a fault indication signal acquisition module, a cellular mobile communication module, a carrier communication module, a serial communication module, a short-range wireless communication module, an actuator control module, a processor module, a storage module, and a security encryption module.

[0017] In the above scheme, the signal test module is used to test the integrated functions integrated in the fusion terminal, such as the integrated voltage, current, and power data acquisition and analysis capabilities, built-in communication capabilities, and the control capabilities of the terminal equipment. The signal line interface is the signal line interface on the fusion terminal that realizes relevant data acquisition and data output, that is, the signal test module is used by the test device to test the integrated functions of the fusion terminal. Since the implementation of relevant data connection generally does not rely on the implementation of a multi-pin serial port module, there is no need to configure a third interface or lead wire as a signal transfer physical structure; the above provides the specific selection of standard modules. When the test device is testing, it combines the extension module type corresponding to the reserved extension module interface on the fusion terminal to select the corresponding type of standard module to complete the fusion terminal expansion performance test.

[0018] The standard modules are respectively equipped with a self-test indicator light fixed on the device panel and a second interface. The self-test indicator light is used to indicate the self-test result of the standard module through light, and the second interface serves as a standard module line self-test interface.

[0019] In the above scheme, the self-test indicator light is used to indicate whether the standard module is intact through light indication, and the second interface is the self-test data interface of the standard module. As a person skilled in the art, configuring a standard module with a self-test indicator light and a second interface is a conventional technical means. The above limitation only configures the position of the self-test indicator light and the second interface on the test device, and does not involve improvements to the computer program.

[0020] The installation station is configured with a plurality of standard modules.

[0021] In the above solution, multiple standard modules are used to adapt to the test requirements of the converged terminal for multiple extension modules, and to improve the test efficiency of the extension modules. In specific applications, different standard modules simulate different extension modules.

[0022] It also includes a tooling plate that is detachably connected to the device panel, the installation station is located on the tooling plate, and a fixing device for fixing the fusion terminal is provided on the tooling plate.

[0023] The above scheme is intended to address the following problems: when using a test device to conduct a fusion terminal performance test, the device panel is placed flat or tilted. After the test is completed, it is necessary to disconnect the standard module, signal test module and related interfaces. In particular, for the serial port module commonly used in the expansion module interface, the device panel itself has a fixed performance for the fusion terminal, which will facilitate the removal of the interface. In this scheme, the fixing device used is used to fix the fusion terminal on the tooling board, so that the device panel can constrain the fusion terminal when completing the removal action to facilitate the removal of the interface; the tooling board is used to provide a secure connection for the fusion terminal. The installation station is designed to achieve: for fusion terminals of different appearances, it provides differentiated requirements for the specific shape and size of the installation station / fixture device. In specific applications, customized adaptive tooling boards are provided for different types of fusion terminals. When this test device is used to test different types of fusion terminals, the installation station / fixture device is adapted to the fusion terminal by replacing the tooling board. That is, when different types of fusion terminals need to be tested, it is only necessary to replace the tooling board on the device panel to adapt the test device to the fixing needs of the fusion terminal, thereby achieving the purpose of improving the adaptability of this test device to different types of fusion terminals.

[0024] The fixing device includes a hanging rod and a clamping device, wherein the hanging rod is arranged on the front side of the tooling plate and is centered on the tooling plate and in the width direction of the clamping space, and the clamping device is arranged on the rear side of the tooling plate;

[0025] The front side of the hanging rod is provided with a groove body located on the side of the hanging rod;

[0026] The clamping device includes two elastic clamping plates installed on the tooling plate. The two elastic clamping plates are distributed on the left and right sides of the tooling plate. A clamping space for clamping the fusion terminal is formed between the two elastic clamping plates.

[0027] The above scheme provides a specific fixing device. The structural setting of this fixing device is intended to adapt to the fusion terminal being set as a square box structure, and a hanging plate is connected to the top and back sides, and a plate hole is set on the hanging plate. When the above fixing device is in use, the hanging rod is first inserted into the plate hole. When the hanging plate and the groove body are located at the same axial position of the hanging rod, the fusion terminal is pulled back to make the hanging plate embedded in the groove body. At this time, the hanging rod is in a state of constraining the position of the hanging plate in the axial direction and radial direction of the hanging rod, and then, the lower end of the fusion terminal is pressed down and clamped into the clamping space between the two elastic splints. In this way, the hanging rod and the groove body thereon are used to constrain the hanging plate to complete the constraint of the fixing device on the upper end of the fusion terminal, and the elastic splint is used to complete the constraint of the fixing device on the lower end of the fusion terminal. When fixing the fusion terminal, the fixing device provided above can be fixed on the fixing device by moving the fusion terminal, and there is no need to adjust the fixing device itself. When removing the fusion terminal from the device panel, it is only necessary to pull and lift the fusion terminal. By pulling, the elastic clamp is first released from the rear end of the fusion terminal, and then the fusion terminal is lifted up to release the constraint of the trough on the hanging plate, and the fusion terminal can be removed. Therefore, the above fixing device has the characteristics of simple structure and easy use. In specific application, the elastic clamp is used to clamp the lower end of the fusion terminal, that is, the fusion terminal is installed on the device panel as follows: the upper end of the fusion terminal is located on the front side of the tooling plate, and the lower end of the fusion terminal is located on the rear side of the tooling plate.

[0028] The elastic splint is a bent plate with a bend, and the shape of the clamping space formed by the inner wall of the bent plate is: in the depth direction of the clamping space, the width of the clamping space at the outer end of the bend continuously decreases from the outside to the inside, and the inner end of the bend has a clamping space with a width that continuously increases from the outside to the inside, and the clamping position of the clamping device for the fusion terminal is located on the clamping space with a width that continuously increases from the outside to the inside.

[0029] The above scheme provides a specific implementation form of the elastic clamp, which aims to facilitate the installation and disassembly of the fusion terminal in the clamping space and ensure the clamping reliability. Specifically, the clamping space at the outer end of the bend forms an introduction section for introducing the fusion terminal into the clamping space, and the width of the introduction section continuously decreases from the outside to the inside, which is used to efficiently guide the fusion terminal to be embedded in the inner side of the bend. The clamping space at the inner end of the bend forms a specific clamping position of the fusion terminal between the elastic clamps. During use, the process of embedding the fusion terminal into the clamping space is to squeeze the elastic clamp from the side of the fusion terminal to expand the width of the clamping space. After crossing the bending position, the elastic clamp rebounds, and the clamping position is used to reliably constrain the fusion terminal to the device panel. When the fusion terminal needs to be removed, the lower end of the fusion terminal is lifted up to make it detached from the clamping of the elastic clamp, and the specific use is: when the back of the fusion terminal is in contact with the mounting plate, the hanging plate and the slot body are located at the same axial position of the hanging rod, and the fusion terminal sinks to the inner end of the bend.

[0030] The outer wall of each elastic splint includes a flexible pad layer, and the flexible pad layer serves as a contact layer between the elastic splint and the fusion terminal.

[0031] In the above scheme, the flexible cushion layer serves as a friction-reducing layer on the outside of the elastic splint, and is used to prevent scratches from being formed on the outer wall of the fusion terminal during the contact and extrusion process between the elastic splint and the fusion terminal. The flexible cushion layer preferably adopts a cloth cover fixed on the elastic splint. For example, compared with the rubber cover, the cloth cover can optimize the smoothness of the fusion terminal entering and exiting the clamping space.

[0032] The standard module forms a pluggable connection relationship with the device panel via a first interface fixed on the device panel.

[0033] In the above scheme, the first interface serves as the connection interface between the standard module and the device panel. The specific implementation method of the first interface preferably adopts a serial port module to achieve: the first interface not only provides the detachable fixing function of the standard module on the device panel, but also provides the communication function between the standard module and the test device control module.

[0034] There are multiple installation stations, and each installation station is configured with a standard module.

[0035] In the above solution, multiple installation stations are used to enable the test device to provide test functions for multiple converged terminals at the same time, so as to improve the test efficiency of the test device.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] This solution provides a technical solution for indirectly connecting the standard module and the expansion module interface based on a third interface and a lead wire, solving the problem of loss of the standard module on the test device after multiple plugging and unplugging. Based on the pin socket made of transparent material on the lead wire, a visual connection between the pin group and the pins is achieved, which facilitates the correct plugging of the pins and the implementation of correct pin connection inspection.

[0046] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0047] Example 1:

[0048] like Figure 1-Figure 5 As shown, an embodiment of the present utility model provides a power grid intelligent fusion terminal test device, including a device panel 1, on which is configured an installation station 5 for installing a fusion terminal 6, and further comprising a plurality of standard modules 14 for connecting to an expansion module interface 15 on the fusion terminal 6, wherein the standard modules 14 are respectively configured with a third interface 13 fixed on the device panel 1, the third interface 13 serving as a lead wire interface of the standard module 14, the third interface 13 being configured with a lead wire 9, the lead wire 9 being used to realize an electrical connection between the expansion module interface 15 and the third interface 13;

[0049] The lead wire 9 includes a cable 93, a pin socket 92 provided at the end of the cable 93, and a pin 91 fixed on the pin socket 92. The pin socket 92 is made of a transparent material.

[0050] In the above scheme, the device panel 1 serves as the test panel of the test device, the installation station 5 is the installation position on the device panel 1 for installing the fusion terminal 6 to be tested, and the standard module 14 is a test module configured on the test device for connecting to the expansion module interface 15 on the fusion terminal 6. Usually, the expansion module of the fusion terminal 6 is simulated by the standard module 14. When the standard module 14 tests that the fusion terminal 6 is well compatible with various expansion modules, it means that the fusion terminal 6 can mount the relevant type of expansion module and realize the relevant functions of the expansion module. In a specific application environment, the user can selectively connect these expansion modules to the fusion terminal 6 according to usage needs, so that the relevant expansion functions can be reliably realized by the fusion terminal 6.

[0051] The above is the basic principle and function of the test device of the power grid intelligent fusion terminal 6. This solution is aimed at these standard modules 14, which usually need to be connected and separated with the expansion module interface 15 on the fusion terminal 6 through plugging and unplugging. During the repeated plugging and unplugging of the standard module 14, the connector position is easily damaged after multiple plugging and unplugging. At the same time, the connector position forms a pin group based on the pin 91. When the pin group is incorrectly connected to the pins of the relevant interface, possible situations may include test failure and damage to the standard module 14. A method is provided to realize indirect connection between the standard module 14 and the expansion module interface 15 based on the third interface 13 and the lead wire 9, and based on the pin seat 92 made of transparent material on the lead wire 9, a visual connection between the pin group and the pin is realized, so as to solve the loss problem of the standard module 14 on the test device after multiple plugging and unplugging, facilitate the correct plugging of the pin 91, and implement the correct connection check of the pin 91.

[0052] Specifically, when using the present test device to test the extension module of the fusion terminal 6, the standard module 14 is used as an analog module of the extension module or as an extension module that can be directly mounted on the extension module interface 15, and is connected to the extension module interface 15 through the third interface 13 and the lead wire 9. In this way, unlike the traditional fusion terminal 6 test in which the standard module 14 is directly connected to the extension module interface 15, since the third interface 13 and the lead wire 9 are used to realize the transfer between the fusion terminal 6 and the standard module 14, the connection and separation between the fusion terminal 6 and the standard module 14 only needs to be plugged in and out of the lead wire 9 on the extension module interface 15. In this way, when the present test device is repeatedly used for fusion When testing the fusion terminal 6, the plugging and unplugging of the existing standard module 14 and the expansion module interface 15 is changed to the plugging and unplugging of the lead wire 9 and the expansion module interface 15, and the damage that may occur to the pin 91 on the standard module 14 interface is transferred to the pin 91 of the lead wire 9. With this solution, there is no problem of the standard module 14 blocking the position matching of the pin 91 and the expansion module interface 15 when the standard module 14 is plugged into the fusion terminal 6. This solution not only facilitates the plugging and unplugging of the standard module 14 relative to the fusion terminal 6, but also, when the pin 91 is damaged due to the increased use of the lead wire 9, it is only necessary to replace the lead wire 9 to restore the testing capability of the test device. In this solution, the pin holder 92 on the lead wire 9 is further configured to be a transparent structure, and the specific material can be, for example, acrylic material. In this way, when connecting the pin 91 on the lead wire 9 to the expansion module interface 15, the transparent property of the pin holder 92 can be used to observe the relative position of the pin 91 and the pin on the expansion module interface 15 and to determine the specific connection position of the pin 91 on the pin. The property of the pin holder 92 being a transparent material not only facilitates the rapid matching of the relative positions of the pin 91 and the pin, but also, when the lead wire 9 and the expansion module interface 15 remain connected, it is also possible to check by observation whether the pin 91 is correctly connected to the correct pin of the expansion module interface 15, thereby assisting in completing the correct insertion of the pin 91 and verifying the correct insertion of the pin 91, and facilitating the rapid troubleshooting of possible faults in the event of test failure.

[0053] As a person skilled in the art, in the existing fusion terminal 6 expansion performance test, the standard module 14 is an important module on the test device for simulating the expansion module. In the prior art, these standard modules 14 need to be directly connected to the expansion module interface 15 on the fusion terminal 6 through the pins 91 thereon. In this solution, the connection between the standard module 14 and the fusion terminal 6 is achieved through the third interface 13 and the lead wire 9. The actual improvement lies in changing the physical connection structure to achieve indirect connection between the standard module 14 and the fusion terminal 6. The standard module 14 needs to be used repeatedly, thereby reducing the number of plugging and unplugging times on the standard module 14 interface during the test, thereby solving the problem that the standard module 14 is easily damaged after repeated plugging and unplugging, resulting in increased test loss. Therefore, the improvement in the connection method between the standard module 14 and the fusion terminal 6 in this solution is only in the improvement of the physical structure, and does not involve computer programs or computer program improvements; and the pin holder 92 is made of transparent material, which is also limited to the selection of the lead wire 9 or the pin holder 92 material, and does not involve material improvements.

[0054] At the same time, as a person skilled in the art, connecting the standard module 14 to the expansion module interface 15 to perform expansion module compatibility testing on the fusion terminal 6 is only part of the test of the fusion terminal 6. For example, the fusion terminal 6 generally integrates basic data acquisition functions, data processing functions, communication functions, and control instruction output functions. If these functions are to be tested, when the signal test module 8 used to test these integrated functions is wired to the relevant data interface on the fusion terminal 6, first, the signal test module 8 does not need to be directly mounted on the data interface. Secondly, these wired connections usually do not need to use the serial port module based on multiple pins 91 and pins used by the expansion module interface 15, that is, the interface on the signal test module 8 for establishing a wired connection is not easily damaged during repeated use. Therefore, it is easy to understand that the core idea of ​​the improvement of the test device in this scheme is to change the physical connection link connecting the standard module 14 and the expansion module interface 15.

[0055] It should be noted that in Figure 1 In the embodiment, the fusion terminal 6 is installed only on the two installation stations 5 of the device panel 1.

[0056] Example 2:

[0057] This embodiment is further refined based on the embodiment 1:

[0058] It also includes a signal testing module 8, which is used to connect to the signal line interface of the fusion terminal 6;

[0059] The standard module 14 is one or more of a current signal acquisition module, a voltage signal acquisition module, a power signal acquisition module, an analog / switch signal acquisition module, a fault indication signal acquisition module, a cellular mobile communication module, a carrier communication module, a serial communication module, a short-range wireless communication module, an actuator control module, a processor module, a storage module, and a security encryption module.

[0060] In the above scheme, the signal test module 8 is used to test the integrated functions integrated in the fusion terminal 6, such as the integrated voltage, current, and power data acquisition and analysis capabilities, the built-in communication capabilities, and the control capabilities of the terminal equipment. The signal line interface is the signal line interface on the fusion terminal 6 that realizes relevant data acquisition and data output, that is, the signal test module 8 is used by the test device to test the integrated functions of the fusion terminal 6. Since the implementation of relevant data connection generally does not rely on the serial port module with multiple pins 91, there is no need to configure the third interface 13 and the lead wire 9 as a physical structure for signal conversion; the above provides a specific selection of the standard module 14. When the test device is testing, it combines the extension module type corresponding to the reserved extension module interface 15 on the fusion terminal 6 to select the corresponding type of standard module 14 to complete the extension performance test of the fusion terminal 6.

[0061] Example 3:

[0062] This embodiment is further refined based on the embodiment 1:

[0063] The standard module 14 is respectively equipped with a self-test indicator light 11 and a second interface 12 fixed on the device panel 1. The self-test indicator light 11 is used to indicate the self-test result of the standard module 14 through light, and the second interface 12 serves as a line self-test interface of the standard module 14.

[0064] In the above scheme, the self-test indicator light 11 is used to indicate whether the standard module 14 is intact through light indication, and the second interface 12 is the self-test data interface of the standard module 14. As a person skilled in the art, the standard module 14 configured with the self-test indicator light 11 and the second interface 12 is a conventional technical means. The above limitation only configures the position of the self-test indicator light 11 and the second interface 12 on the test device, and does not involve improvements to the computer program.

[0065] Example 4:

[0066] This embodiment is further refined based on the embodiment 1:

[0067] The installation station 5 is equipped with a plurality of standard modules 14 .

[0068] In the above solution, the multiple standard modules 14 are used to adapt to the test requirements of the converged terminal 6 for the multiple extension modules, so as to improve the test efficiency of the extension modules. In specific applications, different standard modules 14 simulate different extension modules.

[0069] Example 5:

[0070] This embodiment is further refined based on the embodiment 1:

[0071] It also includes a tooling plate 4 detachably connected to the device panel 1 , the installation station 5 is located on the tooling plate 4 , and a fixing device for fixing the fusion terminal 6 is provided on the tooling plate 4 .

[0072] The above scheme is intended to address the following problems: when using a test device to test the performance of the fusion terminal 6, the device panel 1 is placed horizontally or tilted. After the test is completed, it is necessary to disconnect the standard module 14, the signal test module 8 and the relevant interfaces. In particular, for the serial port module commonly used in the expansion module interface 15, the device panel 1 itself has a fixed performance for the fusion terminal 6, which will facilitate the removal of the interface. In this scheme, the fixing device used is used to fix the fusion terminal 6 on the tooling plate 4, so that the device panel 1 can constrain the fusion terminal 6 when completing the removal action to facilitate the removal of the interface; the tooling plate 4 is used to provide a secure connection for the fusion terminal 6. The installation station 5 is intended to achieve: for fusion terminals 6 of different shapes, differentiated requirements are provided for the specific shape and size of the installation station 5 / fixture device. In specific applications, customized adaptive tooling plates 4 are provided for different models of fusion terminals 6. When this test device is used to test different models of fusion terminals 6, the installation station 5 / fixture device is adapted to the fusion terminal 6 by replacing the tooling plate 4. That is, when different models of fusion terminals 6 need to be tested, it is only necessary to replace the tooling plate 4 on the device panel 1 to adapt the test device to the fixing needs of the fusion terminal 6, thereby achieving the purpose of improving the adaptability of this test device to different models of fusion terminals 6.

[0073] Example 6:

[0074] This embodiment is further refined based on embodiment 5:

[0075] The fixing device includes a hanging rod 3 and a clamping device 2, wherein the hanging rod 3 is arranged on the front side of the tooling plate 4, and the hanging rod 3 is arranged on the tooling plate 4 and in the center of the width direction of the clamping space 22, and the clamping device 2 is arranged on the rear side of the tooling plate 4;

[0076] The front side of the hanging rod 3 is provided with a groove body 31 located on the side of the hanging rod 3;

[0077] The clamping device 2 includes two elastic clamping plates 21 installed on the tooling plate 4 . The two elastic clamping plates 21 are distributed on the left and right sides of the tooling plate 4 . A clamping space 22 for clamping the fusion terminal 6 is formed between the two elastic clamping plates 21 .

[0078] The above scheme provides a specific fixing device. The structural setting of this fixing device is intended to adapt to the fusion terminal 6 being set as a square box structure, and a hanging plate 7 is connected to the top and back sides, and a plate hole is set on the hanging plate 7. When the above fixing device is in use, the hanging rod 3 is first inserted into the plate hole. When the hanging plate 7 and the groove body 31 are located at the same axial position of the hanging rod 3, the fusion terminal 6 is pulled back to make the hanging plate 7 embedded in the groove body 31. At this time, the hanging rod 3 is in a state of constraining the position of the hanging plate 7 in the axial direction and radial direction of the hanging rod 3, and then, the lower end of the fusion terminal 6 is pressed down and clamped into the clamping space 22 between the two elastic clamps 21. In this way, the hanging rod 3 and the groove body 31 thereon are used to constrain the hanging plate 7 to complete the constraint of the fixing device on the upper end of the fusion terminal 6, and the elastic clamp 21 is used to complete the constraint of the fixing device on the lower end of the fusion terminal 6. When the fixing device provided above is used to fix the fusion terminal 6, the fusion terminal 6 can be fixed on the fixing device by moving the fusion terminal 6, and there is no need to adjust the fixing device itself. When the fusion terminal 6 is removed from the device panel 1, it is only necessary to pull and lift the fusion terminal 6. After the elastic clamp 21 is first released from the rear end of the fusion terminal 6 by pulling, the fusion terminal 6 is lifted up to release the constraint of the slot 31 on the hanging plate 7, and the fusion terminal 6 can be removed. Therefore, the above fixing device has the characteristics of simple structure and easy use. In specific use, the elastic clamp 21 is used to clamp the lower end of the fusion terminal 6, that is, the fusion terminal 6 is installed on the device panel 1 as follows: the upper end of the fusion terminal 6 is located on the front side of the tooling plate 4, and the lower end of the fusion terminal 6 is located on the rear side of the tooling plate 4.

[0079] Example 7:

[0080] This embodiment is further refined based on embodiment 6:

[0081] The elastic clamping plate 21 is a bent plate with a bend, and the shape of the clamping space 22 formed on the inner wall of the bent plate is: in the depth direction of the clamping space 22, the width of the clamping space 22 at the outer end of the bend continuously decreases from the outside to the inside, and the inner end of the bend has a clamping space 22 with a width that continuously increases from the outside to the inside. The clamping position of the clamping device 2 on the fusion terminal 6 is located on the clamping space 22 with a width that continuously increases from the outside to the inside.

[0082] The above scheme provides a specific implementation form of the elastic splint 21, which is intended to facilitate the installation and disassembly of the fusion terminal 6 on the clamping space 22 and ensure the clamping reliability. Specifically, the clamping space 22 at the outer end of the bend forms an introduction section for introducing the fusion terminal 6 into the clamping space 22, and the width of the introduction section continuously decreases from the outside to the inside, which is used to efficiently guide the fusion terminal 6 to be embedded into the inner side of the bend. The clamping space 22 at the inner end of the bend forms a specific clamping position of the fusion terminal 6 between the elastic splints 21. In use, the fusion terminal 6 is embedded into the clamping space 22. The process of closing the terminal 6 is that the side of the fusion terminal 6 squeezes the elastic clamp 21 to expand the width of the clamping space 22. After passing the bending position, the elastic clamp 21 rebounds, and the fusion terminal 6 is reliably constrained on the device panel 1 by using the clamping position. When the fusion terminal 6 needs to be removed, the lower end of the fusion terminal 6 is lifted up to make it free from the clamping of the elastic clamp 21. The specific application is: when the back of the fusion terminal 6 is attached to the mounting plate, the hanging plate 7 and the slot body 31 are located at the same axial position of the hanging rod 3, and the fusion terminal 6 sinks to the inner end of the bend.

[0083] Example 8:

[0084] This embodiment is further refined based on embodiment 6:

[0085] The outer wall of the elastic splint 21 includes a flexible pad layer, and the flexible pad layer serves as a contact layer between the elastic splint 21 and the fusion terminal 6 .

[0086] In the above scheme, the flexible cushion layer serves as a friction-reducing layer on the outside of the elastic splint 21, and is used to prevent scratches from being formed on the outer wall of the fusion terminal 6 during the contact and extrusion process between the elastic splint 21 and the fusion terminal 6. The flexible cushion layer preferably adopts a cloth cover fixed on the elastic splint 21. For example, compared with the rubber cover, the cloth cover can optimize the smoothness of the fusion terminal 6 entering and exiting the clamping space 22.

[0087] Example 9:

[0088] This embodiment is further refined based on the embodiment 1:

[0089] The standard module 14 forms a pluggable connection relationship with the device panel 1 via a first interface 10 fixed on the device panel 1 .

[0090] In the above scheme, the first interface 10 serves as the connection interface between the standard module 14 and the device panel 1. The specific implementation method of the first interface 10 preferably adopts a serial port module to achieve: the first interface 10 not only provides the detachable fixing function of the standard module 14 on the device panel 1, but also provides the communication function between the standard module 14 and the test device control module.

[0091] Example 10:

[0092] This embodiment is further refined based on the embodiment 1:

[0093] There are multiple installation stations 5 , and each installation station 5 is configured with a standard module 14 .

[0094] In the above solution, the plurality of installation stations 5 are used to enable the test device to provide test functions for the plurality of converged terminals 6 at the same time, so as to improve the test efficiency of the test device.

[0095] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
