Description

Technical Field

[0001] The utility model relates to the technical field of controller online testing, in particular to a controller online testing device. Background Art

[0002] During the manufacturing process of CECU (domain controller, central electronic control unit), EOL (End of Line Test) test is often carried out before going offline to conduct comprehensive functional testing of CECU to ensure that all functions and performance of CECU are normal before it is officially launched on the market. The current common practice is to design a special EOL test fixture and use it in conjunction with the test cabinet at the equipment. The EOL test fixture can be detachably installed on the test cabinet, and there may be a variety of different types of EOL test fixtures depending on the specific CECU. Therefore, when performing online testing on CECU, it is often necessary to change the EOL test fixture. When the EOL test fixture is installed with the cabinet, it is generally necessary to lead the air pipes and signal lines on the EOL test fixture into the cabinet for air connection and wiring. In the prior art, the cabinet is provided with two lead-in ports for the air pipe and signal line of the EOL test fixture to pass through, so as to extend into the cabinet for air connection and wiring. This process is very cumbersome when the EOL test fixture needs to be replaced: when installing the EOL test fixture, the air pipe and signal line need to be led into the cabinet for manual air connection and wiring. When changing the model, the air pipe and signal line need to be manually removed, and the above operation needs to be repeated for the next EOL test fixture to be installed. This process greatly affects the test efficiency of CECU. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a controller online test device, which can save the steps of manually introducing the air pipe and / or signal line into the cabinet through the lead-in port of the cabinet and then manually connecting the air and wiring or removing it when installing or disassembling the EOL test fixture, thereby greatly improving the test fixture change efficiency and test efficiency.

[0004] According to one aspect of the present application, a controller online testing device is provided, comprising a cabinet and a test fixture body for being installed on the cabinet.

[0005] The cabinet is provided with at least one first connection head, and the test fixture body is provided with at least one second connection head.

[0006] The setting position of at least one of the second terminals on the test fixture body corresponds to the setting position of one of the first terminals on the cabinet to form a terminal group, so that when the test fixture body is installed on the cabinet, the first terminal of the same terminal group is plugged and connected with the second terminal.

[0007] The controller online test device of the utility model forms a terminal head group by setting the second terminal head on the test fixture body and the first terminal head on the cabinet in corresponding positions, so that when the test fixture body is installed on the cabinet, the first terminal head and the second terminal head of the same terminal head group can be accurately aligned, so as to achieve accurate plug-in docking under the drive of the driving structure such as the cylinder and the hydraulic cylinder, thereby eliminating the steps of manual wire pulling and manual wiring. When the test fixture body is removed to change the test fixture body, it is only necessary to disassemble and remove the test fixture body, and the first terminal head and the second terminal head of the same terminal head group can be automatically disassembled. The formed terminal head group can be used to connect the EOL test fixture with the air pipe, signal line or other wiring or pipelines that need to be connected to the cabinet, thereby effectively improving the test fixture change efficiency and improving the test efficiency. The controller online test device of the utility model is not only suitable for the online test device when the CECU is performing EOL, but also suitable for other controller online test devices or online test devices, which are not listed here one by one.

[0008] In some embodiments, the cabinet is provided with a first driving assembly, the first wiring head is provided on the first driving assembly, and the first driving assembly is used to drive the first wiring head to move toward the second wiring head;

[0009] and / or,

[0010] The test fixture body is provided with a second driving component, the second wiring head is provided on the second driving component, and the second driving component is used for driving the second wiring head to move toward the first wiring head.

[0011] Therefore, by such an arrangement, when the test fixture body is installed on the cabinet, the first connection head and the second connection head will not directly collide with each other, thereby avoiding damage to the first connection head and the second connection head.

[0012] In some embodiments, the first terminal is disposed on a surface of a cabinet for mounting a test fixture body, and the second terminal is disposed on a surface of the test fixture body for mounting on a cabinet.

[0013] Therefore, through such an arrangement, it can be ensured that after the test fixture body and the cabinet are installed, the first terminal and the second terminal of the same terminal group can ensure accurate alignment, so as to achieve accurate plug-in and docking under the drive of a driving structure such as a cylinder or a hydraulic cylinder. At the same time, such an arrangement can also prevent the first terminal from protruding too much on the cabinet, and the second terminal from protruding too much on the test fixture body, so that the structure of the cabinet and the test fixture body is more compact.

[0014] In some embodiments, the formed terminal block group is a terminal block group for connecting an air pipe and / or connecting a signal line.

[0015] Therefore, through such an arrangement, one or more groups of terminal head groups can realize precise alignment of air pipes and signal lines as needed, so as to realize precise automatic plug-in and docking connection under the drive of driving structures such as cylinders and hydraulic cylinders, so that there is no need to manually connect the air pipes or signal lines when the EOL test fixture is installed with the cabinet, thereby effectively improving the changeover efficiency of the test fixture and improving the test efficiency.

[0016] In some embodiments, the first terminal and / or the second terminal is a Harding connector.

[0017] Therefore, by such an arrangement, using the Harding connector as the connection structure of the first terminal and / or the second terminal can effectively achieve quick plug-in, and it has good sealing and high precision, thereby effectively improving the changeover efficiency of the test fixture.

[0018] In some embodiments, a mounting alignment structure is provided between the cabinet and the test fixture body.

[0019] Therefore, through such a configuration, the installation alignment structure can be used to ensure that the test fixture body is accurately positioned when installed on the cabinet, which can make the test fixture body more convenient and quick when changing models, and can ensure that the terminal head group can be accurately aligned when the test fixture body is installed on the cabinet, so as to achieve precise plug-in and docking under the drive of driving structures such as cylinders and hydraulic cylinders, effectively improving the changeover efficiency of the test fixture body.

[0020] In some embodiments, the mounting alignment structure includes a plug-in structure disposed on one of the cabinet or the test fixture body, and a socket disposed on the other of the cabinet or the test fixture body and corresponding to the plug-in structure.

[0021] Therefore, through such an arrangement, the connection between the plug-in structure and the jack can enable the test fixture body to be quickly aligned with the cabinet when it is installed.

[0022] In some embodiments, the mounting alignment structure includes a telescopic plunger disposed on one of the cabinet or the test fixture body, and a limiting structure disposed on the other of the cabinet or the test fixture body and cooperating with the telescopic plunger.

[0023] Therefore, through such a configuration, the cooperation between the telescopic plunger and the limiting structure can be utilized to limit the test fixture body, so that after the test fixture body is installed on the cabinet, the telescopic plunger and the limiting structure can be used to limit the test fixture body in an installed state, thereby achieving rapid installation of the test fixture body, and ensuring a stable connection between the first terminal head and the second terminal head, thereby effectively improving the changeover efficiency of the test fixture body.

[0024] In some embodiments, the telescopic plunger is disposed on a cabinet, and the limiting structure includes a limiting plate disposed on a test fixture body. When the test fixture body is installed on the cabinet, the telescopic plunger protrudes to clamp the limiting plate between the telescopic plunger and the cabinet.

[0025] Therefore, by such an arrangement, the limit plate is clamped between the telescopic plunger and the cabinet, thereby ensuring that the test fixture body can be clamped in the installed position, ensuring that the test fixture body cannot be easily detached, achieving rapid installation of the test fixture body, and avoiding loosening of the first terminal and the second terminal.

[0026] In some embodiments, the telescopic plunger is disposed on a cabinet, and the limiting structure includes a clamping hole disposed on a test fixture body, and when the test fixture body is mounted on the cabinet, the telescopic plunger is clamped into the clamping hole.

[0027] Therefore, through such a configuration, the snap-fit ​​cooperation between the telescopic plunger and the snap-fit ​​hole can be utilized to ensure that the test fixture body can be fixed in the installed position, ensure that the test fixture body cannot be easily detached, achieve rapid installation of the test fixture body, and avoid loosening of the first terminal and the second terminal.

[0028] In some embodiments, a product fixing structure for mounting and fixing a product is disposed on the test fixture body.

[0029] Therefore, through such an arrangement, the product fixing structure can be used to position and fix the product to be tested placed on the test fixture body, thereby avoiding displacement of the product during testing, which affects the test accuracy and test results.

[0030] In some embodiments, the product fixing structure includes a telescopic assembly disposed on a test fixture body, a movable end of the telescopic assembly is hinged with a first connecting rod, a second connecting rod is hinged on the first connecting rod, and a middle portion of the second connecting rod is hinged to a fixed end of the telescopic assembly.

[0031] Therefore, through such an arrangement, when the movable end of the telescopic assembly is extended, the first connecting rod can be driven to rotate, thereby driving the second connecting rod to rotate, so that the second connecting rod is pressed onto the product to fix the product. When the movable end of the telescopic assembly is retracted, the first connecting rod can be driven to rotate, thereby driving the second connecting rod to rotate, so that the second connecting rod is opened and the fixation of the product is released.

[0032] In some embodiments, the test fixture body is provided with a wiring plug for connecting to a product, and the wiring plug is provided with a circumferential floating structure.

[0033] Therefore, through such a configuration, the axial floating structure can effectively alleviate the difficulty in alignment when the test fixture body is connected to the product due to the large relative position tolerance between the wiring plug and the connector on the product, thereby reducing the docking difficulty when the test fixture body is connected to the product, avoiding the failure of the probe module on the wiring plug to be correctly introduced into the connector of the product, improving the speed of connecting the test fixture body to the product, improving the overall test yield, and thus improving the test efficiency.

[0034] In some embodiments, the circumferential floating structure includes a positioning member configured to align and position the product, the wiring plug is provided with a through hole for the positioning member to pass through, the positioning member is arranged on the wiring plug through the through hole, and a floating space is provided between the through hole and the positioning member.

[0035] Therefore, through such an arrangement, the floating space between the through-hole and the positioning piece can be utilized, so that after the wiring plug is connected to the product, there can be a certain position adjustment under the action of the floating space, thereby effectively alleviating the situation that the alignment is difficult when the test fixture body is connected to the product due to the large relative position tolerance between the wiring plug and the connector on the product, thereby reducing the docking difficulty when the test fixture body is connected to the product, improving the speed of connecting the test fixture body to the product, and thus improving the test efficiency and test yield.

[0036] In some embodiments, a portion of the positioning member located on a side of the wiring plug away from the side for connecting to the product is provided with a tapered structure, the tapered structure comprising a first end and a second end, the first end being away from the wiring plug relative to the second end, the second end being smaller in size than the through hole, and the first end being larger in size than the through hole.

[0037] Therefore, through such a setting, when the wiring plug is connected to the product through the positioning piece, the positioning piece can be quickly moved to the middle position of the perforation by utilizing the tapered structure, thereby ensuring that the probe module on the wiring plug can be accurately introduced into the connector of the product when the test fixture is connected to the product for testing, thereby improving the overall test yield.

[0038] In some embodiments, the tapered structure is a conical surface.

[0039] Therefore, by setting up in this way, setting a conical surface on the positioning piece can utilize the cooperation between the conical surface and the through-hole, so that the positioning piece can be quickly moved to the middle of the through-hole, thereby ensuring that the probe module on the wiring plug can be accurately introduced into the connector of the product when the test fixture is connected to the product for testing, thereby improving the overall test yield.

[0053] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0055] Figures 1 to 3 The controller online testing device of one embodiment of the utility model is schematically shown, referring to Figures 1 to 3 As shown, the controller online testing device of the utility model comprises a cabinet 1 and a test fixture body 2 ( Figure 2 and Figure 3Only the panel on the cabinet 1 for mounting the test fixture body 2 is shown. It is understandable that when the test fixture body 2 is in use, it needs to be connected to the cabinet 1 to communicate with the cabinet 1 and record test data, etc., or use the functional modules of the cabinet 1 to test the controller. The test fixture body 2 and the cabinet 1 are not matched one by one. A plurality of completely different types of test fixture bodies 2 can be installed and adapted on the same cabinet 1, and the same test fixture body 2 can also be installed and connected with different cabinets 1 to detect different controllers or test and record different items. Therefore, the cabinet 1 is provided with at least one first terminal 31 for connecting to the test fixture body 2, and the test fixture body 2 is provided with at least one second terminal 32 for connecting to the cabinet 1, and the setting position of at least one of the second terminals 32 on the test fixture body 2 corresponds to the setting position of one of the first terminals 31 on the cabinet 1 to form a terminal group. The first terminal 31 and the second terminal 32 of the same terminal group, when the test fixture body 2 is installed on the cabinet 1, because the setting positions of the first terminal 31 and the second terminal 32 correspond, the two can be accurately aligned, so that accurate plug-in connection can be achieved under the drive of a driving structure such as a cylinder or a hydraulic cylinder, and automatic plug-in can be achieved.

[0056] Among them, the first terminal head 31 can be arranged on the cabinet 1 in a fixed connection, or can be installed on the cabinet 1 in a detachable connection or the like, and can also be installed on the cabinet 1 through a first drive component 33, and the first drive component 33 is used to drive the first terminal head 31 toward the second terminal head 32. Similarly, the second terminal head 32 can be arranged on the test fixture body 2 in a fixed connection, or can be installed on the test fixture body 2 in a detachable connection or the like, and can also be installed on the test fixture body 2 through a second drive component, and the second drive component is used to drive the second terminal head 32 toward the first terminal head 31. Among them, the first drive component 33 and the second drive component can both be drive structures such as cylinders and hydraulic cylinders. In this embodiment, since the test fixture body 2 needs to be replaced, the general structure is relatively portable and simple, so the second terminal 32 is generally set to be directly installed on the test fixture body 2, and the first terminal 31 is set to be installed on the cabinet 1 through a driving structure such as a cylinder or a hydraulic cylinder, which can effectively avoid the damage to the structure of the first terminal 31 and the second terminal 32 caused by the installation accuracy error during installation. When in use, it is only necessary to ensure that when the test fixture body 2 is installed and connected to the cabinet 1, the second terminal 32 is relatively fixedly set on the test fixture body 2, and the first terminal 31 is relatively fixedly set on the cabinet 1, so that the first terminal 31 and the second terminal 32 of the same terminal group can be plugged and connected to each other.

[0057] The cabinet 1 is used to install the test fixture body 2 to provide module and performance support for the functions required by the test fixture body 2 when testing the product 52. The settings of the test circuits, functional modules, etc. inside the cabinet 1 can be specifically adjusted according to the different test fixture bodies 2 that need to be installed. Therefore, the test circuits and functional modules set inside different cabinets 1 may be different, and then the test fixture bodies 2 that can be installed in the corresponding cabinets 1 will also be different. Therefore, the same test fixture 2 may need to be connected to different cabinets 1 to test different functions of the product 52, and the same cabinet 1 may also be able to connect different test fixtures 2 to test different products 52.

[0058] Specifically, a plurality of first terminals 31 may be provided on the cabinet 1, and these first terminals 31 may be first terminals 31 for connecting to the first test fixture body, or first terminals 31 for connecting to the second test fixture body. Similarly, a plurality of second terminals 32 may be provided on the test fixture body 2, and these second terminals 32 may be second terminals 32 for connecting to the first cabinet, or second terminals 32 for connecting to the second cabinet. Taking the first test fixture body and the first cabinet as an example, the first test fixture body needs to be installed on the first cabinet for use when in use, and then at least one of the second wiring heads 32 on the first test fixture body corresponds to one of the first wiring heads 31 on the first cabinet, or multiple second wiring heads 32 on the first test fixture body correspond to one of the first wiring heads 31 on the first cabinet, or one of the second wiring heads 32 on the first test fixture body corresponds to multiple first wiring heads 31 on the first cabinet, and then these first wiring heads 31 and second wiring heads 32 form a wiring head group, and there is a corresponding relationship between the setting positions of the first wiring head 31 and the second wiring head 32 of the same wiring head group. Through this position correspondence, when the first test fixture body is installed on the first cabinet, the first wiring head 31 and the second wiring head 32 of the same wiring head group can be aligned, and then precise plug-in connection can be achieved under the drive of a driving structure such as a cylinder or a hydraulic cylinder, thereby eliminating the steps of manual wire pulling and manual wiring. Similarly, after the installation between the first test fixture body and the first cabinet is removed, since the first terminal head 31 is relatively fixedly arranged on the cabinet 1, and the second terminal head 32 is relatively fixedly arranged on the test fixture body 2, the connection between the first terminal head 31 and the second terminal head 32 will also be automatically disassembled as the test fixture body 2 is disassembled.

[0059] There is no mandatory requirement for the setting position of the first terminal 31 on the cabinet 1 and the setting position of the second terminal 32 on the test fixture body 2. It is only necessary to ensure that the setting positions of the first terminal 31 and the second terminal 32 of the same terminal group correspond to each other. For example, taking the test fixture body 2 installed on the upper surface of the cabinet 1 as an example, the first terminal 31 can be set on the side of the cabinet 1 and bend and extend in the vertical upward direction, and the second terminal 32 can be set on the side of the test fixture body 2 and bend and extend in the vertical downward direction. At this time, it is only necessary to ensure that the setting positions of the first terminal 31 and the second terminal 32 correspond to each other, so that the test fixture body 2 can be installed on the cabinet 1. After the two are plugged in and connected, the effect of mutual plugging can be achieved. As one of the preferred embodiments, the setting position of the first terminal 31 can be set on the side of the cabinet 1 for installing the test fixture body 2, and the setting position of the second terminal 32 can be set on the side of the test fixture body 2 for installation on the cabinet 1. This arrangement can first ensure that after the test fixture body 2 and the cabinet 1 are installed, the first terminal 31 and the second terminal 32 are oriented in opposite directions, making it easier to ensure the automatic plug-in connection between the two. At the same time, it can also prevent the first terminal 31 from protruding too much on the cabinet 1, and the second terminal 32 from protruding too much on the test fixture body 2, making the structure of the cabinet 1 and the test fixture body 2 more compact. For example, referring to Figure 3 and Figure 4 As shown, in Figure 3 and Figure 4 In the illustrated embodiment, an opening 12 corresponding to the test fixture body 2 is provided in the middle of a panel on the cabinet 1 for mounting the test fixture body 2, a first terminal 31 is installed below the panel through a first drive assembly 33, and corresponds to the opening 12 and is arranged toward the opening 12, while a second terminal 32 of the test fixture body 2 is arranged at the bottom thereof. When the test fixture body 2 is mounted on the panel, the second terminal 32 passes through the panel to extend into the interior of the cabinet 1 and is aligned with the first terminal 31 on the cabinet 1. The first terminal 31 moves toward the second terminal 32 driven by the first drive assembly 33, thereby completing the docking and plugging of the first terminal 31 and the second terminal 32.

[0060] In an embodiment of an online test device for a domain controller, the terminal head group formed between the test fixture body 2 and the cabinet 1 can be a terminal head group for connecting an air pipe and / or connecting a signal line. Exemplarily, the terminal head group formed between the test fixture body 2 and the cabinet 1 can be provided with two groups, which are used to connect the air pipe and the signal line respectively, so that the EOL test fixture can be quickly installed, eliminating the steps of manual wire pulling and manual wiring, effectively improving the test fixture change efficiency, and improving the test efficiency. Further, the terminal head group formed between the test fixture body 2 and the cabinet 1 can also be provided with only one group, in which the air pipe and the signal line are integrated, so that when the terminal head group is plugged and connected, the air pipe and the signal line can be connected at the same time, so that the EOL test fixture can be quickly installed, eliminating the steps of manual wire pulling and manual wiring, effectively improving the test fixture change efficiency, and improving the test efficiency. The first terminal 31 and the second terminal 32 can also be configured as Harding connectors. The connection structure of the Harding connector can effectively realize the quick connection between the two. At the same time, it has good sealing performance and high precision, which can effectively improve the installation speed of the test fixture body 2 and improve the conversion efficiency of the test fixture body 2. Figure 3 As shown, in Figure 3 In the illustrated embodiment, two second terminals 32 are provided on the test fixture body 2, and two first terminals 31 are provided on the cabinet 1, and two terminal groups are formed to respectively correspond to connecting the air pipe and connecting the signal line. The two second terminals 32 on the test fixture body 2 are both provided on a side for installation on the cabinet 1, and the two first terminals 31 on the cabinet 1 are both provided on a side for installing the test fixture body 2, so that the structures of the test fixture body 2 and the cabinet 1 can be more compact, and the first terminals 31 and the second terminals 32 can be more easily connected and plugged.

[0061] As a possible implementation, an installation alignment structure may be further provided between the cabinet 1 and the test fixture body 2. The installation alignment structure is used for quick alignment and quick installation between the cabinet 1 and the test fixture body 2. Since the first terminal 31 is relatively fixedly provided on the cabinet 1, and the second terminal 32 is also relatively fixedly provided on the test fixture body 2, when the installation between the test fixture body 2 and the cabinet 1 can be fast and accurate, the first terminal 31 and the second terminal 32 of the same terminal group can be quickly and automatically plugged in and docked. The installation alignment structure may be provided as a conventional structure in the prior art, such as a slide block structure and a snap-on structure. In some possible implementations, the installation alignment structure may be provided as including a plug-in structure 42 and a socket 41 corresponding to the plug-in structure 42, wherein the plug-in structure 42 may be provided on one of the cabinet 1 or the test fixture body 2, and the socket 41 may be provided on the other of the cabinet 1 or the test fixture body 2. Exemplarily, referring to Figure 4 As shown, in Figure 4 In the illustrated embodiment, the plug-in structure 42 may be a locating pin, which is arranged around the cabinet 1 and is provided with four locating pins, while the sockets 41 are provided on the test fixture body 2 and are provided with four locating pins corresponding to the positions of the locating pins. The positioning alignment between the four locating pins and the sockets 41 enables the test fixture body 2 to be accurately installed on the cabinet 1 at the installation position for installing the test fixture body 2, so that the first terminal 31 and the second terminal 32 can be quickly aligned to achieve automatic docking and plugging. As a preferred solution, a conical surface structure may also be provided on one end of the locating pin for insertion into the socket 41, so that it can be more conducive to the alignment between the locating pin and the socket 41, reduce the difficulty of manual alignment, improve the conversion efficiency of the test fixture body 2, and improve the test efficiency. Among them, in addition to being a locating pin, the plug-in structure 42 may also be other structures that can cooperate with the socket 41, such as a plug structure, as long as it can meet the corresponding technical effects and comply with the corresponding technical principles.

[0062] Furthermore, for the installation alignment structure, it can also include a telescopic plunger 43 and a limiting structure cooperating with the telescopic plunger 43, wherein the telescopic plunger 43 can be set on one of the cabinet 1 or the test fixture body 2, and the limiting structure can be set on the other of the cabinet 1 or the test fixture body 2. As for the limiting structure, it is a structure used to cooperate with the telescopic plunger 43 to limit the test fixture body 2 to a position installed on the cabinet 1, thereby preventing the first terminal 31 and the second terminal 32 from loosening. The limiting structure can be a limiting plate 44 set on the test fixture body 2, and the telescopic plunger 43 is set on the cabinet 1, so that the telescopic plunger 43 clamps the limiting plate 44, limits the test fixture body 2 away from the cabinet 1, and limits the test fixture body 2 to a position installed on the cabinet 1. The limiting structure may also be a limiting block provided on the cabinet 1, in which case the telescopic plunger 43 is provided on the test fixture body 2, so that the telescopic plunger 43 cooperates with the limiting block to clamp the limiting block, thereby limiting the test fixture body 2 from being away from the cabinet 1, and limiting the test fixture body 2 to a position installed on the cabinet 1. The limiting structure may also be a clamping hole provided on the test fixture body 2 or the cabinet 1, in which case the telescopic plunger 43 needs to be provided on the other of the test fixture body 2 or the cabinet 1, and when the telescopic plunger 43 is inserted into the clamping hole, the test fixture body 2 can be directly limited from being away from or close to the cabinet 1, and limiting the test fixture body 2 to a position installed on the cabinet 1. It should be noted that the setting of the telescopic plunger 43 and the limiting structure does not depend on the setting of the plug-in structure 42 and the jack 41, and the corresponding limiting function can be achieved by only setting the telescopic plunger 43 and the limiting structure. For example, referring to Figure 5 As shown, in Figure 5 In the illustrated embodiment, the telescopic plunger 43 is disposed at a position on the cabinet 1 for mounting the test fixture body 2, and the limiting structure is the bottom plate of the test fixture body 2, and the bottom plate is used as the limiting plate 44, so that when the test fixture body 2 is mounted on the cabinet 1 using the locating pins, the telescopic plunger 43 can be compressed to allow the telescopic plunger 43 to rebound and get stuck on the bottom plate of the test fixture body 2, so as to limit the test fixture body 2 from being away from the cabinet 1, thereby limiting the test fixture body 2 at the position where it is mounted on the cabinet 1, and preventing the first terminal 31 and the second terminal 32 from loosening.

[0063] As some possible implementations, a product fixing structure 21 for installing and fixing the product may be provided on some test fixture bodies 2. Among them, the product fixing structure 21 may be provided on both sides of the test fixture body 2, and its function is to position and fix the product 52 placed on the test fixture body 2, so as to avoid displacement of the product 52 during testing, which affects the test accuracy and test results. The product fixing structure 21 may adopt a conventional structure in the prior art, such as a snap-fit ​​structure, so that after the product 52 is placed on the test fixture body 2, the movement can be restricted under the action of the snap-fit ​​structure, or a telescopic plunger or pin or other structure may be used in conjunction with a positioning portion (such as a positioning hole, etc.) designed on the product 52 to restrict the product 52 placed on the test fixture body 2 from detaching.

[0064] Specifically, in this embodiment, the product fixing structure 21 can also be configured to include a telescopic component 211 arranged on the test fixture body 2, the movable end of the telescopic component 211 is hinged with a first connecting rod 213, the first connecting rod 213 is also hinged with a second connecting rod 214, and the middle part of the second connecting rod 214 is hinged with the fixed end of the telescopic component 211, so that when the movable end of the telescopic component 211 is extended, it will drive the first connecting rod 213 to drive the second connecting rod 214 to rotate around the hinge position between it and the telescopic component 211, so that the second connecting rod 214 can press and fix the product 52 on the test fixture body 2. For example, refer to Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the product fixing structure 21 in the present embodiment in an open state. Figure 7 2 is a schematic diagram of the pressed state of the product fixing structure 21 in this embodiment. In this embodiment, the product fixing structure 21 is specifically arranged on both sides of the test fixture body 2, the telescopic component 211 can be a cylinder, and the test fixture body 2 is provided with a mounting frame 212 for mounting the cylinder. When the cylinder is arranged on the test fixture body 2, its movable end is upward so that it can be adjusted in the vertical direction (such as Figure 5 The movable end of the cylinder 210 is hinged to one end of the first connecting rod 213, the other end of the first connecting rod 213 is hinged to one end of the second connecting rod 214, and the middle part of the second connecting rod 214 is hinged to the mounting frame 212 for mounting the cylinder, so that the middle part of the second connecting rod 214 is hinged to the fixed end of the telescopic assembly 211. When the movable end of the cylinder retracts, the fixed structure 21 of the whole product will be Figure 6 In the state shown, the second connecting rod 214 is rotated and opened, and when the movable end of the cylinder is extended, the entire product fixing structure 21 will be Figure 7In the state shown, the second connecting rod 214 is rotated and pressed onto the product 52 to position and fix the product 52, thereby preventing the product from shifting during testing, which would affect the test accuracy and test results.

[0065] As some other possible implementations, a wiring plug 51 is also provided on some test fixture bodies 2. The wiring plug 51 is mainly used to connect with the product 52 to obtain product 52 data or to copy the operation of part of the functions of the product 52, and then test the product 52. Specifically, a bracket for installing the wiring plug 51 can be provided on one side of the position on the test fixture body 2 for installing the product 52, so that the wiring plug 51 can be set on the test fixture body 2 to achieve connection with the product 52 installed on the test fixture body 2. Among them, a circumferential floating structure can be provided on the wiring plug 51. The circumferential floating structure is used to alleviate the situation that the test fixture body 2 is connected to the product 52 due to the large relative position tolerance between the wiring plug 51 and the connector on the product 52, which is easy to be difficult to align. It can reduce the difficulty of docking when the test fixture body 2 is connected to the product 52, avoid the probe module on the wiring plug 51 from being correctly introduced into the connector of the product 52, improve the speed of connecting the test fixture body 2 to the product 52, improve the overall test yield, and thus improve the test efficiency. In some possible embodiments, the circumferential floating structure may include a positioning member 61 disposed on the wiring plug 51 for aligning and positioning with the product 52, and a through hole for the positioning member 61 to pass through is also provided on the wiring plug 51, and the positioning member 61 passes through the through hole to connect with the corresponding hole structure on the product 52, and a floating space 63 is provided between the through hole and the positioning member 61, so that when the wiring plug 51 is docked with the product 52, the positioning member 61 can be aligned with the corresponding hole on the product 52, and when the relative position tolerance is relatively large, the position of the positioning member 61 can be appropriately adjusted through the floating space 63 to achieve overcoming the tolerance and continuing to align and connect with the product 52. The positioning member 61 may be a connecting bolt, and the bolt passes through the through hole to connect with the corresponding screw hole on the product 52, thereby achieving the connection between the wiring plug 51 and the product 52.

[0066] Furthermore, in some possible embodiments, a tapered structure 62 may be provided on the positioning member 61, and the tapered structure 62 includes a first end and a second end. The first end is an end on the positioning member 61 that is farther away from the second end and is used to insert the product 52, and the size of the second end is smaller than the through-hole, and the size of the first end is larger than the through-hole. The tapered structure 62 may specifically be a slope structure or a conical surface structure. When the tapered structure 62 is provided on the positioning member 61, when the positioning member 61 passes through the through-hole and is connected to the corresponding hole structure on the product 52, the positioning member 61 will be quickly moved to the middle of the through-hole under the initial positioning guide of the tapered structure 62, so that when the positioning member 61 is connected to the product 52, it is ensured that the probe module on the wiring plug 51 can be accurately introduced into the connector of the product 52 when the test fixture is connected to the product 52 for testing, thereby improving the overall test yield. For example, referring to Figure 8 As shown, in Figure 8 In the illustrated embodiment, the positioning member 61 is a connecting bolt, a floating space 63 is provided between the connecting bolt and the through hole, and a conical surface is provided on the side of the bolt head close to the through hole. When the bolt passes through the through hole and is connected with the corresponding screw hole on the product 52, the bolt will be quickly centered to the middle of the through hole after being positioned and guided by the tapered bolt head, thereby ensuring that the probe module on the wiring plug 51 can be accurately introduced into the connector of the product 52 when the test fixture is connected to the product 52 for testing, thereby improving the overall test yield.

[0067] When the controller online test device of the utility model is used, the positioning alignment between the test fixture body 2 and the cabinet 1 can be first achieved by installing the positioning pins and the jack 41 of the alignment structure, and the test fixture body 2 can be clamped in the installation position of the cabinet 1 by using the telescopic plunger 43. At this time, the second terminal 32 on the test fixture body 2 will automatically connect and plug with the corresponding first terminal 31 on the cabinet 1, thereby eliminating the steps of manual wire pulling and manual wiring. When using the test fixture body 2, the circumferential floating structure can be used to achieve fast and accurate connection between the wiring plug 51 on the test fixture body 2 and the product 52. When removing the test fixture body 2 or changing the test fixture body 2, it is only necessary to release the limit of the telescopic plunger 43, disassemble and remove the test fixture body 2, and the first terminal 31 and the second terminal 32 of the same terminal group can be automatically disassembled. The formed terminal group can be used to connect the EOL test fixture with the air pipe, signal line or other wiring or pipelines that need to be connected to the cabinet 1, thereby effectively improving the test fixture change efficiency and improving the test efficiency. The controller online test device of the utility model is not only suitable for online test devices when CECU is performing EOL, but also can be applied to other controller online test devices or online test devices, which are not listed here one by one.
