[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The core of this application is to provide a movable test equipment connector for a maglev train controller, which can greatly improve the testing efficiency of the maglev train controller. Another core aspect of this application is to provide a testing system including the aforementioned movable test equipment connector for a maglev train controller.

[0039] This application provides a movable test equipment connector for a maglev train controller, used for signal connection to a controller under test. The movable test equipment connector for a maglev train controller includes a support component 1 and a test body 2. The support component 1 is detachably connected to the controller under test, and the test body 2 is movably disposed on the support component 1 along a first direction. The test body 2 has a female plug at a first end along the first direction and a signal transmission unit at a second end for connection to a test system. The test system is used to test the controller, and the female plug is signal-connected to the signal transmission unit.

[0040] refer to Figure 1 and Figure 2 As can be seen, the support component 1 can adopt a U-shaped frame or a flat plate structure, etc. One end of the support component 1 along the X direction is provided with a movable connecting part. The movable connecting part can adopt an openable snap-fit ​​structure or a rotatable hook, etc., so as to be detachably connected to the end of the controller to be tested that is provided with a male plug of type ODU plug.

[0041] Correspondingly, a test body 2 is provided above the support component 1. The test body 2 can be a rectangular tube or a U-shaped groove, etc., and the bottom structure of the test body 2 slides with the support component 1 so as to be able to move along the X direction. A female plug is provided at the left end of the test body 2 along the X direction for plugging into the male plug of the controller so as to realize the signal connection with the controller during the test. A signal transmission unit is provided at the right end of the test body 2 along the X direction for signal connection to the test system used to test the controller so as to realize the signal connection with the test system during the test. The female plug is connected to the signal transmission unit, and then the signal is transmitted between the female plug and the signal transmission unit.

[0042] Optionally, in some embodiments, the aforementioned female plug is an ODU socket, in which case the movable test equipment connection device can be used to test a maglev train controller with a male plug that is an ODU plug. Of course, the aforementioned female plug is not limited to the aforementioned ODU socket, as long as it meets the connection requirements with the male plug provided by the maglev train controller.

[0043] In use, the movable test equipment connector is moved to the location of the controller to be tested, and the female plug of the movable test equipment connector is plugged into the male plug of the controller. The signal transmission unit is then connected to the test system, which enables the controller signal to be connected to the test system used to test the controller. This greatly improves the testing efficiency of the maglev train controller and is beneficial for mass production testing of faults.

[0044] It should be noted that there are no restrictions on the type of signal transmission unit, as long as it meets the signal connection requirements of the test system. For example, the signal transmission unit can be a socket, in which case the plug at the end of the cable connected to the test system is plugged into the signal transmission unit. Alternatively, the signal transmission unit can include a cable and a quick-connect plug, with the fixed end of the cable connected to the female plug and the quick-connect plug located at the movable end of the cable. In which case the quick-connect plug is plugged into the signal transmission interface of the test system.

[0045] Based on the above embodiments, the support assembly 1 includes a force-bearing plate 11 and at least a pair of movable parts 12; the two force-bearing plates 11 are arranged opposite to each other, and the test body 2 is movably arranged between the two force-bearing plates 11, with the first direction perpendicular to the line connecting the two force-bearing plates 11; one of the paired movable parts 12 is located on one of the two force-bearing plates 11, and the other is located on the other of the two force-bearing plates 11, and the two of the paired movable parts 12 are located on the same side of the corresponding force-bearing plate 11 along the first direction of the test body 2; the two of the paired movable parts 12 can move towards or away from each other to clamp or release the controller.

[0046] refer to Figure 1 As explained, in the support component 1, two force plates 11 are arranged opposite to each other, and the two force plates 11 have an active channel extending along the X direction to accommodate the test body 2 and meet its space requirements for moving along the X direction. The two force plates 11 are the main load-bearing and main installation structure in the plug-in device of the movable test equipment.

[0047] Furthermore, a pair of movable parts 12 are provided at the left end of the two force-bearing plates 11 along the X direction. The two movable parts 12 are respectively provided on the two force-bearing plates 11. If the two movable parts 12 can move towards each other, the distance between the two movable parts 12 will decrease. Conversely, if the two movable parts 12 can move away from each other, the distance between the two movable parts 12 will increase. In other words, the pair of movable parts 12 are openable and closable components.

[0048] When using, refer to Figure 1 The structure shown is positioned such that, firstly, the two movable parts 12 in the pair are controlled to move away from each other, so that as the movable test equipment connector moves along the X direction toward the controller, the two movable parts 12 in the pair can move to a position where one is on the left side of the controller and the other is on the right side. Then, the two movable parts 12 in the pair are controlled to move toward each other until they both contact the side of the controller to clamp it, thus achieving a temporary fixed connection between the movable test equipment connector and the controller. When it is necessary to separate the movable test equipment connector from the controller, the operation process is the reverse of the above-described process of achieving a temporary fixed connection. Therefore, the structure of the support component 1 is simple and the operation is convenient.

[0049] Based on the above embodiment, the paired movable parts 12 each have a snap-fit ​​protrusion 121 on the side close to each other. The snap-fit ​​protrusion 121 is used to be inserted into the groove on the side of the controller to snap and engage with the controller.

[0050] refer to Figure 1 To improve the stability and reliability of the connection between the movable component 12 and the controller, each of the paired movable components 12 has a snap-fit ​​protrusion 121 extending toward the other on its inner side. The snap-fit ​​protrusion 121 can be a trapezoidal block or a rectangular strip, etc. When in use, when the two movable components 12 in the paired arrangement move toward each other to clamp the controller, the snap-fit ​​protrusion 121 is embedded in the groove on the side of the controller.

[0051] It should be noted that the type of moving part 12 is not limited, as long as it can meet the requirement of snapping onto the controller. Some examples are provided for illustration:

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the movable component 12 has a flat main structure, and the main structure of the movable component 12 is an extension of the force plate 11. That is, the main structure of the movable component 12 is located on the end extension line of the force plate 11. Preferably, the top surface of the main structure is flush with the top surface of the movable component 12 to which it is connected, and the bottom surface of the main structure is flush with the bottom surface of the movable component 12 to which it is connected. Correspondingly, the locking protrusion 121 of the movable component 12 is a long strip structure, and the locking protrusion 121 extends vertically.

[0053] In some embodiments, the movable component 12 is a bent rod of type L, F, or E, and the end of the main support structure of the movable component 12 is connected to the force plate 11, while the branch structure of the movable component 12 is connected to the main support structure. For ease of understanding, in the above examples of movable components 12, the L-type movable component 12 has one branch structure and one main support structure, the F-type movable component 12 has two branch structures and one main support structure, and the E-type movable component 12 has three branch structures and one main support structure; and the number of pairs of movable components 12 is at least two, and several pairs of movable components 12 are arranged along the height direction of the force plate 11.

[0054] Based on the above embodiment, the movable part 12 is connected to the force plate 11 by a threaded fastener 3. The threaded fastener 3 is inserted at the lap joint between the force plate 11 and the movable part 12 and is threadedly engaged with the movable part 12.

[0055] refer to Figure 1 As can be seen, in this embodiment, a threaded fastener 3 is configured. Correspondingly, the force plate 11 and the movable part 12 overlap or lap together at their near ends to form a lap joint. The part of the force plate 11 and the movable part 12 that forms the lap joint is provided with threaded through holes for inserting the threaded fastener 3 and engaging with the threaded fastener 3. Thus, during the process of tightening the threaded fastener 3, the threaded fastener 3 can use its connection position with the force plate 11 as a fulcrum to push the movable part 12 to move.

[0056] It should be noted that the type of movable connection structure between the movable part 12 and the force plate 11 is not limited to the threaded fastener 3 mentioned above. As long as it satisfies the opening and closing of both of the paired movable parts 12, for example, an electric telescopic rod or a sprocket and chain structure can also be provided between the movable part 12 and the force plate 11.

[0057] refer to Figure 1As can be seen, based on the above embodiment, the test body 2 is provided with a first sliding part 21 on both sides, and a second sliding part is provided on the inner side of both force plates 11. The test body 2 is movably connected by the first sliding part 21 and the second sliding part through sliding engagement. When in use, a thrust along the X direction is applied to the test body 2, that is, under the action of the sliding engagement of the first sliding part 21 and the second sliding part, the test body 2 can move in the preset direction, i.e., the X direction.

[0058] It should be noted that the types of the first sliding part 21 and the second sliding part are not limited, as long as the sliding fit between the test body 2 and the support component 1 is satisfied. Some embodiments are listed below for illustration:

[0059] In some embodiments, the first sliding part 21 is a slider, and the second sliding part is a groove. The slider can be movably inserted into the groove, thereby guiding the movement of the test body 2 through the second sliding part.

[0060] In some embodiments, the first sliding part 21 is a guide rail, and the second sliding part includes two rows of positioning posts. Preferably, the positioning posts are bolts, and the head ends of a plurality of positioning posts are used to restrict the first sliding part 21 so that it cannot disengage along the depth direction of the channel between the two rows of positioning posts. The first sliding part 21 can move through the channel extending in the X direction between the two rows of positioning posts, thereby restricting the movement direction of the first sliding part 21 by the second sliding part and guiding the test body 2.

[0061] Based on the above embodiment, the bottom of both sides of the test body 2 is provided with positioning guide rails 22, which are used to slide and fit with the guide rail grooves on both sides of the controller, and the positioning guide rails 22 extend along the first direction.

[0062] refer to Figure 1 and Figure 2 As explained, a positioning guide rail 22 is provided at the lower left corner of the test body 2. The right end of the positioning guide rail 22 extending along the X direction is fixed to the test body 2. When the movable test equipment plug-in device is used to connect the controller and the test system, the process of controlling the connection between the female plug of the movable test equipment plug-in device and the ODU plug of the controller is as follows: First, adjust the pair of movable parts 12 to open, then push the left ends of the two positioning guide rails 22 into the guide rail grooves on the corresponding side of the controller to achieve the positioning of the movable test equipment plug-in device and the controller. Continue to push the movable test equipment plug-in device to the left. After the movable part 12 moves into place, adjust the pair of movable parts 12 to move closer together to clamp the controller. Then, push the test body 2 to the left until the female plug of the movable test equipment plug-in device and the ODU plug of the controller are plugged in and engaged.

[0063] Conversely, after the test is completed, pull the test body 2 to the right so that the female plug of the movable test equipment connector is disengaged from the ODU plug of the controller. Then, adjust the pair of movable parts 12 to open, and pull the movable test equipment connector to the right again until the positioning guide rail 22 is disengaged from the guide rail groove of the controller.

[0064] Based on the above embodiment, a U-shaped handle 4 is also included; the connecting rod of the handle 4 is located at the top of the test body 2, one side wall of the handle 4 is rotatably connected to the left side structure of the test body 2 and the force plate 11 located on the left side of the test body 2, and the other side wall is rotatably connected to the right side structure of the test body 2 and the force plate 11 located on the right side of the test body 2.

[0065] refer to Figure 1 To reduce the difficulty of connecting the female plug of the movable test equipment to the ODU plug of the controller by pushing the test body 2, a U-shaped handle 4 is also provided. The handle 4 is located between the two force plates 11 and on both sides of the test body 2. The left side wall of the handle 4 is rotatably connected to the left side of the test body 2 and the left force plate 11, while the right side wall of the handle 4 is rotatably connected to the right side of the test body 2 and the right force plate 11. For easy gripping, the top of the left side wall and the top of the right side wall of the handle 4 extend upwards to the top of the force plate 11 and the test body 2. The connecting rod is connected to the top of the left side wall and the top of the right side wall of the handle 4, so that the tester can easily grip the part of the connecting rod located directly above the test body 2 to push the test body 2 to move.

[0066] Based on the above embodiment, the test body 2 includes a rectangular truss 201, a top plate 202, a bottom plate 203, a left side plate 204, and a right side plate 205; the top plate 202 is laid on the top of the rectangular truss 201, and the bottom plate 203 is laid on the bottom of the rectangular truss 201; the left side plate 204 is laid on the left side of the rectangular truss 201, and the right side plate 205 is laid on the right side of the rectangular truss 201, and the test body 2 slides and engages with the load-bearing plate 11 through its own left side plate 204 and right side plate 205.

[0067] refer to Figure 1 As explained, the rectangular truss 201 is the main force transmission structure of the test body 2, and the top plate 202, bottom plate 203, left side plate 204 and right side plate 205 laid on the rectangular truss 201 form a cylindrical test body 2. Both ends of the test body 2 along the X direction are open to facilitate the installation of the female plug and signal transmission unit.
