Description

Technical Field

[0001] This application relates to the technical field of PLC controller upgrade testing, and particularly to an interface adapter and a testing device. Background Art

[0002] The J63A series of rectangular connectors have a soft plug and unplug operation and reliable locking, and are commonly used in the interconnection of various electrical circuit systems with high density, miniaturization, light weight, and high reliability requirements. According to the number of connector cores, they can be divided into nine specifications: 9-core, 15-core, 21-core, 25-core, 31-core, 37-core, 51-core, 65-core, and 69-core.

[0003] When upgrading or testing existing communication equipment, such as when upgrading or testing a PLC controller, due to the height dimension limitations of the device under test, there are many types of debugging connectors, and small connector adapters need to be used to lead out the corresponding connectors. Therefore, J63A miniature connectors are selected. During actual debugging, the test terminal (host computer) needs to be connected to the device under test through the J63A connector, and the software of the test terminal (host computer) is used to upgrade or test the device under test.

[0004] When the test terminal (host computer) is specifically connected to the device under test and upgrades or tests it. Taking the 31-core J63A connector as an example, the existing J63A miniature connector includes a plug and 31 scattered wires on one side. When specifically connecting, the plug of the J63A connector is connected to the device under test, and the scattered wires on one side of the connector need to be fixed to different corresponding connectors of the test terminal. However, during actual debugging, since the aperture of the J63A is less than 0.4 mm and the diameter of the debugging wire is small, if the scattered wires of the connector plug are directly fixed to the corresponding connectors of the test terminal, the debugging wire is easily broken and the communication effect is poor.

However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the disclosure of the present application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of the present application can be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0028] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0029] Throughout the specification, when an element such as a layer, region, or substrate is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on" the other element, "connected to" the other element, "coupled to" the other element, "above" the other element, or "covering" the other element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0030] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0031] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, the first component, element, region, layer, or part described in the examples herein could also be termed the second component, element, region, layer, or part without departing from the teachings of the examples.

[0032] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0033] The terms used herein are for describing various examples only and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprising," "including," and "having" enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0034] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Accordingly, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0035] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible, as will be apparent after understanding the disclosure of the present application.

[0036] Before the present application was filed, when a test terminal was specifically connected to a device under test and upgraded or tested. Taking the 31-core J63A connector as an example, the existing J63A micro-connector includes a plug and 31 scattered wires on one side thereof. When specifically connecting, the plug of the J63A connector is connected to the device under test, and the scattered wires on one side of the connector need to be fixed to different corresponding connectors of the test terminal. However, during actual debugging and use, since the aperture of the J63A is less than 0.4 mm and the wire diameter of the debugging wire is small, if the scattered wires of the connector plug are directly fixed to the corresponding connectors of the test terminal, the debugging wire is easily broken and the communication effect is poor.

[0037] In view of this, according to a first aspect of the present application, an interface adapter is provided to solve the above-mentioned technical problems. The following refers to Figures 1 to 4 Describe the interface adapter according to some embodiments of the present application.

[0038] As Figure 3 and Figure 4 shown, the interface adapter of the present application includes a J63A connector, a transfer circuit board 200, and a standard connector. Among them, the J63A connector includes a socket 110 and a plug 120. The socket 110 includes jacks and pins. The jacks of the socket 110 are connected to the device under test through the plug 120; the pins of the socket 110 are electrically connected to the transfer circuit board 200, the standard connector is electrically connected to the transfer circuit board 200, and the pins are electrically connected to the standard connector through the transfer circuit board 200; the standard connector is used to connect to the test terminal.

[0039] When the test terminal (for example, a host computer) is connected to the device under test (for example, a PLC controller) to upgrade or test it, the jack of the socket 110 of the J63A connector is connected to the device under test through the plug 120, and then the standard connector is connected to the test terminal for testing. Compared with the prior art, the J63A connector's loose wire connection method is eliminated.

[0040] That is to say, the present application leads the pins of the socket 110 of the J63A connector to the standard connector through the adapter circuit board 200, and then directly connects to the test terminal through the standard connector. That is, the adapter circuit board 200 defines and converts the socket 110 of the J63A connector into one or more standard connectors. Compared with the prior art, the scattered wire connection method of the J63A connector is cancelled to solve the problem of high loss and poor reliability caused by the small diameter of the debugging wire in the specific use of the J63A connector.

[0041] It should be noted that the J63A connector of the present application itself belongs to the prior art. The J63A connector of the present application includes a socket 110 and a plug 120 (such as Figure 3 As shown, the plug 120 is, for example, a double-plug connection line, and the jack of the socket 110 is connected to the device under test through the double-plug connection line). The socket 110 includes a jack ( Figure 4 The exposed sockets) and pins ( Figure 4 The bottom side of the middle socket 110 is connected to the conductive via of the adapter circuit board 200).

[0042] The J63A rectangular connector of the present application is a tiny rectangular connector using a twisted elastic nano-pin, and the pin spacing is 0.635mm. The plug 120 and the socket 110 of the J63A connector of the present application are screwed together and docked through a screw nut assembly 900, which is soft to plug and unplug and reliable to lock. It is often used in the interconnection of various electrical circuit systems with high density, miniaturization, lightness and high reliability requirements. Based on this, the present application leads the pins of the socket 110 of the J63A connector to a standard connector through a transfer circuit board 200, and then directly connects it to the test terminal through a standard connector. That is, the transfer circuit board 200 defines the socket 110 of the J63A connector as one or more standard connectors. Compared with the prior art, the J63A connector's scattered wire connection method is cancelled to solve the problem of high loss and poor reliability caused by the small diameter of the debugging line in the specific use of the J63A connector. The J63A connector of the present application can be divided into nine specifications according to the number of connector cores: 9 cores, 15 cores, 21 cores, 25 cores, 31 cores, 37 cores, 51 cores, 65 cores, and 69 cores. The following description will take the 31-core J63A connector as an example.

[0043] Preferably, in the embodiments of the present application, Figure 4As shown, the number of standard connectors in the present application is multiple. A plurality of conductive vias are provided on the adapter circuit board 200, and the plurality of conductive vias correspond one-to-one with a plurality of pins (for example, there are 31 pins and 31 conductive vias). The pins are electrically connected to the corresponding conductive vias, and the plurality of pins are respectively electrically connected to the plurality of standard connectors via the corresponding conductive vias and wires.

[0044] With such a setting, a plurality of conductive vias are provided on the adapter circuit board 200 of the present application corresponding one-to-one with a plurality of pins, and the pins are electrically connected to the corresponding conductive vias. This design ensures that current can be stably and reliably conducted from the pins to the conductive vias, and then transmitted to the standard connectors through wires, reducing the risk of signal transmission interruption or interference, and ensuring the stability and reliability of the entire circuit system.

[0045] In addition, by arranging a plurality of conductive vias on the adapter circuit board 200 and making a reasonable layout and connection with the pins and standard connectors, the space of the circuit board can be effectively utilized, making the structure of the entire circuit system more compact, which is beneficial to the miniaturization and light weight of the device.

[0046] In addition, this structural design is relatively simple. During the production and manufacturing process, it is easy to realize the connection between the pins, conductive vias, wires and standard connectors, reducing the complexity and cost of the production process.

[0047] As an example, in the embodiment of the present application, as Figure 3 and Figure 4 shown, the plurality of standard connectors include three RS232 connectors 300 and two JTAG connectors 400. When the test terminal is specifically connected to the device under test and tests it, the jacks of the socket 110 of the J63A connector are connected to the device under test through the plug 120. And at the standard connector end, according to the test requirements, the RS232 connector 300 can be connected to the test terminal through the USB to serial cable 310, and / or the JTAG connector 400 can be connected to the test terminal through the JTAG programmer 410.

[0048] Furthermore, in the embodiment of the present application, as Figure 3 and Figure 4 shown, the plurality of standard connectors further include a programming connector 500. Among them, the three RS232 connectors 300, the two JTAG connectors 400, one programming connector 500 and one socket 110 are all arranged on the front side of the adapter circuit board 200. When the test terminal is specifically connected to the device under test and upgrades it, the jacks of the socket 110 of the J63A connector are connected to the device under test through the plug 120. And at the standard connector end, according to the upgrade requirements, the programming connector 500 can be connected to the programmer, or the programming connector 500 can be connected to the test terminal.

[0049] Optionally, in the embodiments of the present application, as Figure 3 shown, the interface adapter of the present application further includes a reset button 600 and a programming button 700. The reset button 600, the programming button 700, three RS232 connectors 300, two JTAG connectors 400, a programming connector 500, and a socket 110 are all arranged on the front side of the adapter circuit board 200.

[0050] The reset button 600 and the programming button 700 of the present application are both electrically connected to the adapter circuit board 200. Multiple pins are respectively electrically connected to a reset button 600, a programming button 700, three RS232 connectors 300, two JTAG connectors 400, and a programming connector 500 via corresponding conductive vias and wires. When the test terminal is specifically connected to the device under test and upgrades it, the jacks of the socket 110 of the J63A connector are connected to the device under test through the plug 120. And for the standard connector end, according to the upgrade requirements, the programming connector 500 can be connected to a programmer, or the programming connector 500 can be connected to the test terminal. In addition, the reset operation (restart operation) of the interface adapter of the present application can be realized through the reset button 600, and the programming button 700 is used to switch the BOOT programming mode. For example, during specific programming, after connecting the programming connector 500 to a programmer or connecting the programming connector 500 to the test terminal, it is necessary to click the programming button 700 to perform programming. At the same time, the RS232 connector 300 can also be connected to the test terminal through a USB to serial cable 310 to read data through the test terminal.

[0051] In addition, in the embodiments of the present application, as Figure 1 and Figure 2 shown, the interface adapter of the present application further includes an upper cover 810 and a lower cover 820 that are docked with each other. Among them, the lower cover 820 is provided with a lower cover 820 accommodation groove for accommodating the adapter circuit board 200, and the upper cover 810 is provided with an upper cover 810 accommodation groove for accommodating the standard connector, the reset button 600, and the programming button 700. And for the convenience of connection, the interfaces of the two JTAG connectors 400, the interface of a programming connector 500, a reset button 600, a programming button 700, the jacks of a socket 110, and the serial ports of the three RS232 connectors 300 are all exposed on the upper cover 810.

[0052] As an example, as Figure 4As shown, the adapter circuit board 200 includes a crown plate portion 220 and a trunk plate portion 210 connected to each other. The trunk plate portion 210 is rectangular, and the crown plate portion 220 includes three branches 221. Three RS232 connectors 300 are respectively arranged at the edges of the three branches 221, and the serial ports of the three RS232 connectors 300 are all facing the peripheral side of the adapter circuit board 200. The socket 110 is arranged at the edge of the trunk plate portion 210, and the jack of the socket 110 is facing the peripheral side of the adapter circuit board 200. The burning connector 500 is arranged at the edge of the trunk plate portion 210, and the interface of the burning connector 500 is facing the peripheral side of the adapter circuit board 200. Two JTAG connectors 400 are arranged in the middle of the adapter circuit board 200, and the interfaces of the two JTAG connectors 400 are all facing the top side of the adapter circuit board 200. The reset button 600 and the burn button 700 are respectively disposed on the edges of the branch portion 221 and the trunk plate portion 210 .

[0053] Correspondingly, such as Figure 2 As shown, the side of the upper cover 810 is provided with three first openings 811, and the three first openings 811 correspond to the serial ports of the three RS232 connectors 300. The side of the upper cover 810 is also provided with a second opening 812, and the second opening 812 corresponds to the jack of the socket 110. The side of the upper cover 810 is also provided with a third opening, and the third opening corresponds to the interface of the burning connector 500. The top of the upper cover 810 is also provided with two fourth openings 814, and the two fourth openings 814 correspond to the interfaces of the two JTAG connectors 400. The side of the upper cover 810 is also provided with a fifth opening 815 for exposing the reset button 600 and the burning button 700.

[0054] Preferably, in the embodiments of the present application, Figure 4 As shown, among the three branch portions 221, the center line of the first one of the three branch portions 221 coincides with the center line of the trunk plate portion 210; the center lines of the other two of the three branch portions 221 are arranged at an acute angle with the center line of the first one, and the other two of the three branch portions 221 are arranged symmetrically about the center line of the first one. Among the three RS232 connectors 300, the first one of the three RS232 connectors 300 is arranged in alignment with the socket 110, and the other two of the three RS232 connectors 300 are arranged symmetrically about the first one.

[0055] In this way, the present application can realize a reasonable layout in a limited space by aligning the midline of one of the three branch portions 221 with the midline of the trunk plate portion 210, and symmetrically arranging the other two with respect to the midline and at an acute angle, and similarly symmetrically arranging the three RS232 connectors 300. This layout is conducive to the efficient transmission of signals between different components, reduces signal interference, and improves the stability and accuracy of signal transmission. At the same time, the symmetrical arrangement makes the entire structure more compact and beautiful.

[0056] In addition, the symmetrical arrangement of the RS232 connectors 300, especially one of which is aligned with the socket 110, facilitates the connection with external devices. When performing connection operations, users can more intuitively find the corresponding interface, reduce the probability of connection errors, and improve the convenience and efficiency of operation. Moreover, this symmetrical layout also facilitates technicians to identify and operate each connector during the maintenance and repair of the equipment, which helps to quickly locate and solve problems.

[0057] In addition, the entire interface adapter has a lightweight and miniaturized body structure, a high degree of interface integration, can be carried by one person, and the body structure is easy to assemble and disassemble.

[0058] In addition, the design presents a cartoon tree structure, with three RS232 connectors 300 extending from three branches of the tree canopy. The design is ingenious and beautiful, and can also be used as a pendant.

[0059] In the embodiments of the present application, Figures 1 to 3 As shown, the upper cover 810 and the lower cover 820 are designed in the shape of the adapter circuit board 200. The upper cover 810 is made of ABS plastic through 3D printing materials, and the overall design is a white tree shape, and the crown part is designed with a boss 816 to be compatible with the larger RS232 connector 300.

The lower cover 820 is made of ABS plastic through 3D printing materials, the base is white, and the overall design is a tree shape. The bottom surface is painted with green and brown pigments to represent the crown and trunk. The inner side of the cavity is used to accommodate the front components of the adapter circuit board 200, and there are four threaded holes designed around it to fix it with the upper cover 810.

[0060] In summary, when the test terminal is specifically connected to the device under test and tests it, the jack of the socket 110 of the J63A connector is connected to the device under test through the plug 120. The end of the standard connector can connect the RS232 connector 300 to the test terminal through the USB to serial port cable 310 and / or connect the JTAG connector 400 to the test terminal through the JTAG burner 410 according to the test requirements.

And at the standard connector end, according to the upgrade requirements, the programming connector 500 can be connected to the programmer, or the programming connector 500 can be connected to the test terminal. In addition, the reset operation (restart operation) of the interface adapter of the present application can be realized through the reset button 600, and the programming button 700 is used to switch the BOOT programming mode. For example, during specific programming, after connecting the programming connector 500 to the programmer or connecting the programming connector 500 to the test terminal, it is necessary to click the programming button 700 to start programming. At the same time, the RS232 connector 300 can also be connected to the test terminal through the USB to serial cable 310 to read data through the test terminal.

[0062] That is to say, in the present application, the pins of socket 110 of the J63A connector are led out through the adapter circuit board 200 to the 3-way RS232 connector 300, 2-way JTAG connector 400, USB programming connector 500, reset button 600, and programming button 700. That is, the adapter circuit board 200 can convert the definition of the J63A connector into the 3-way RS232 connector 300, 2-way JTAG connector 400, USB programming connector 500, reset button 600, and programming button 700. Compared with the prior art, the way of connecting the J63A connector with loose wires is cancelled to solve the problems of high loss and poor reliability caused by the small wire diameter of the debugging wire in the specific use of the J63A connector.

[0063] According to a second aspect of the present application, a test device is provided, and the test device includes the interface adapter as described above.

[0064] Furthermore, the test device further includes a test terminal, a device under test, a USB to serial cable 310, and a JTAG programmer 410. Among them, the device under test is a communication device (such as a PLC controller). The RS232 connector 300 is connected to the test terminal through the USB to serial cable 310; the JTAG connector 400 is connected to the test terminal through the JTAG programmer 410.
