Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a mating and unmating test device and a connector test system. Background Technology

[0002] Connector insertion / removal testing is a testing method used to evaluate the performance and reliability of connectors, and is commonly applied in the manufacturing and maintenance of electronic and electrical equipment. Connector insertion / removal testing primarily uses repeated insertion and removal processes to detect the mechanical and electrical properties of the connector, ensuring that the connector can withstand a specified number of insertions and removals without affecting its function, and verifying whether the connector design meets long-term usage requirements.

[0003] Currently, existing plug-in / plug-out mechanisms typically incorporate a floating mechanism to provide cushioning during connector testing. This floating mechanism includes a tapered guide post and a spring. When the propulsion mechanism moves the floating mechanism, the reaction force generated when the connector contacts the target plug causes the spring on the floating mechanism to compress and the tapered guide post to disengage from its original guide hole. During this compression, the spring provides cushioning, and the increased gap between the tapered guide post and the guide hole allows the floating plate in the floating mechanism to move within a small range, thus achieving flexible plug-in / plug-out. However, in this type of plug-in / plug-out mechanism, due to the small floating range, if the positional deviation between the connector and the target plug is large, they can still collide and damage the components. Utility Model Content

[0004] In view of this, the present invention provides a plugging and unplugging testing device and a connector testing system to solve the problem that existing plugging and unplugging mechanisms are prone to causing damage to the tested parts.

[0005] In a first aspect, this utility model provides an insertion / removal testing device with a third direction. The insertion / removal testing device includes: a moving platform, a connecting component, and a supporting platform. The moving platform has an insertion interface. The connecting component includes a first elastic element and multiple guide components. The moving platform is located on one side of the first elastic element along the third direction, and the supporting platform is located on the other side of the first elastic element along the third direction. One end of the first elastic element is connected to the moving platform, and the other end is connected to the supporting platform. Each guide component includes a guide post and a swing connector. The swing connector is disposed on the supporting platform and fixedly connected to the supporting platform. The guide post extends along the third direction and is swingably inserted through the swing connector. The end of the guide post is magnetically connected to the moving platform.

[0006] Beneficial effects: The mobile platform is connected to the carrier platform through the first elastic element. When the mobile platform is subjected to a large external force, it can drive the guide column to swing together. The first elastic element not only provides support but also provides a restoring force for the swinging mobile platform. When the insertion and removal testing device is not performing a test, the mobile platform maintains its original upright state under the action of the first elastic element and the guide component. When the insertion and removal testing device is performing a test and the external connector is not aligned with the connector interface, the external connector will collide with the test board. At this time, the test board will drive the mobile platform to swing under the action of external force. Since the mobile platform and the guide column are magnetically connected, when the mobile platform swings to a certain amplitude, the mobile platform will automatically release, separating the test board from the external connector, thereby effectively avoiding damage to the test device and providing good protection. This effectively solves the problem that existing insertion and removal mechanisms are prone to damaging the tested parts.

[0007] In one optional embodiment, the mobile platform includes a main body and a connecting seat. The main body has an insertion interface, and a connecting surface is formed on the side of the main body near the carrying platform. The connecting seat is detachably connected to the connecting surface. The side of the connecting seat near the carrying platform is provided with a magnetic connecting position. The connecting positions are arranged one-to-one with the guide components, and the guide posts are magnetically connected to the connecting positions.

[0008] Beneficial effects: This type of mobile platform allows for adjustment of the test board's insertion position along a third direction by changing the main body or connector, making position adjustment easier. In addition, it is not necessary to make the entire mobile platform magnetic; only the connection points on the connector need to be magnetic. The structure is simple, reliable, and easy to manufacture.

[0009] In one alternative embodiment, the wall of the connection position is a first arcuate surface recessed in a direction away from the guide post, and the end of the guide post has a second arcuate surface for engaging with the first arcuate surface.

[0010] Beneficial effects: The first and second arc surfaces work together. When the test plate moves the platform under the action of external force, the platform will first move in translation as the first and second arc surfaces slide relative to each other. This can avoid stress concentration caused by contact between the connection point and the guide post, and also prevent the connection point from separating from the guide post too early.

[0011] In one optional embodiment, a protrusion is provided on the first arc surface, and a corresponding recess is provided on the second arc surface for accommodating the protrusion. The protrusion is a conical protrusion, and the recess is a conical groove.

[0012] Beneficial effects: The protrusion and the recess can play a positioning role. When the moving platform swings slightly and resets, the protrusion and the recess are misaligned but not completely separated. At this time, under the action of magnetic force, the protrusion and the recess have the potential to restore the original matching state, which can make the moving platform more accurately reset to the initial matching position with the guide column.

[0013] In one alternative embodiment, the guide post includes a guide section and a magnetic section. A portion of the guide section passes through the swing connector, and the magnetic section is detachably connected to the end of the guide section near the moving platform. The end of the magnetic section is magnetically connected to the connection position.

[0014] Beneficial effects: The segmented guide column is not only easy to process and manufacture, but also allows for flexible replacement of the specifications and dimensions of the guide section and magnetic section.

[0015] In one alternative embodiment, each guide assembly further includes a second elastic element located between the moving platform and the carrying platform, the second elastic element being sleeved on the outside of the guide post, and the second elastic element being used to support the moving platform.

[0016] Beneficial effects: The second elastic element can improve the stability of the mobile platform, prevent the mobile platform from swinging randomly during normal insertion, and improve test stability.

[0017] In one optional embodiment, the swing connector is a universal ball bearing. The swing connector includes a fixed part and a rotating part. The bearing platform has a through hole for mounting the fixed part. The rotating part is rotatably disposed in the fixed part and has a guide hole for the guide column to pass through. One end of the second elastic member abuts against the connecting seat, and the other end abuts against the rotating part.

[0018] Beneficial effects: This type of guide column, in conjunction with the swing connector, allows the moving platform to move in any direction in space. This not only improves the buffering flexibility of the moving platform, but also enables the insertion and removal testing device to adapt to the insertion testing requirements in any direction within the insertion plane, thus enhancing the testing flexibility of the device.

[0019] In one alternative embodiment, the side of the connecting seat near the bearing platform is provided with an annular groove for abutting and engaging with the second elastic member, and the annular groove is provided circumferentially along the connecting position.

[0020] Beneficial effects: After the annular groove abuts against the second elastic element, it can play a limiting role, preventing the second elastic element from shifting randomly when it is compressed, and reducing the vibration generated when the moving platform moves.

[0021] In one optional embodiment, the insertion and removal testing device further includes a fixed platform, which includes a connecting column and a fixed plate. The fixed plate is located on the side of the support platform away from the moving platform. The fixed plate is fixedly connected to the support platform through the connecting column. The space between the fixed plate and the support platform forms a clearance space for the guide column to pass through.

[0022] Beneficial effects: The fixed platform can raise the supporting platform to a certain height, and the clearance space allows the guide column to extend, retract and swing freely, preventing the guide column from interfering with external components.

[0023] Secondly, this utility model also provides a connector testing system, which includes the above-mentioned insertion and removal testing device. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, an insertion / removal testing device is provided, having a third direction Z, including: a test plate 1, a moving platform 2, a connecting component 3, and a supporting platform 4; the moving platform 2 has an insertion interface 101; the connecting component 3 includes a first elastic element 301 and a plurality of guide components 302; the moving platform 2 is located on one side of the first elastic element 301 along the third direction Z, and the supporting platform 4 is located on the other side of the first elastic element 301 along the third direction Z, one end of the first elastic element 301 is connected to the moving platform 2, and the other end is connected to the supporting platform 4; each guide component 302 includes a guide post 3021 and a swing connector 3022, the swing connector 3022 is disposed on the supporting platform 4 and fixedly connected to the supporting platform 4, the guide post 3021 extends along the third direction Z and is swingably inserted into the swing connector 3022, and the end of the guide post 3021 is magnetically connected to the moving platform 2.

[0041] In the insertion and removal testing device of this embodiment, the moving platform 2 is connected to the bearing platform 4 through the first elastic element 301. When the moving platform 2 is subjected to a large external force, it can drive the guide column 3021 to swing together. The first elastic element 301 not only provides support but also provides a restoring force for the swinging moving platform 2. When the insertion and removal testing device is not performing a test, the moving platform 2 maintains its original upright state under the action of the first elastic element 301 and the guide component 302. When the insertion and removal testing device is performing a test and the external connector is not aligned with the connector 101, the external connector will collide with the connector 101. At this time, the connector 101 will drive the moving platform 2 to swing under the action of external force. Since the moving platform 2 and the guide column 3021 are magnetically connected, when the moving platform 2 swings to a certain amplitude, the moving platform 2 will automatically release, causing the connector 101 to separate from the external connector, thereby effectively avoiding damage to the test device and providing good protection. This effectively solves the problem that existing insertion and removal mechanisms are prone to damaging the tested parts.

[0042] It should be noted that the insertion / removal testing device has three intersecting directions: a first direction X, a second direction Y, and a third direction Z. The first direction X refers to... Figure 1 The middle arrow points to the direction of "X", and the second direction, Y, refers to... Figure 1 The direction indicated by the middle arrow "Y" is the third direction Z. Figure 1 The direction of "Z" indicated by the middle arrow.

[0043] In one possible implementation, a test board 1 is also provided on the mobile platform 2. The mobile platform 2 has a mounting position for installing the test board 1. The test board 1 is detachably connected to the mobile platform 2 and has a plug-in interface 101. The plane containing the first direction X and the second direction Y is the plug-in plane, and the plug-in direction of the plug-in interface 101 is parallel to the plug-in plane.

[0044] Specifically, since the insertion direction of the connector 101 is parallel to the insertion plane, the direction of deviation between the external connector and the connector 101 can be quickly observed by the swinging and moving of the moving platform 2, which facilitates adjustment and alignment. There is no specific limitation on the orientation of the connector 101. It can be oriented towards the first direction X or the second direction Y, as long as the insertion direction of the connector 101 is parallel to the insertion plane.

[0045] Furthermore, there is no limitation on the number and position of the first elastic element 301. It can be one or multiple spaced, and its specifications and dimensions can be selected according to actual needs.

[0046] Furthermore, there is no limitation on the swing direction of the guide post 3021. It can swing in any direction within the insertion plane, or it can only swing in the insertion direction. There is no limitation on the specific type of the swing connector 3022. It can be a universal ball bearing, or a swing sleeve that can swing along the axis of rotation, as long as it can meet the swing requirements of the guide post 3021.

[0047] It is understood that, as an alternative implementation, the guide post 3021 can also be fixedly connected to the swing connector 3022, and the moving platform 2 abuts against the end of the guide post 3021. Under normal conditions, the moving platform 2 remains in its original position. At this time, the moving platform 2 abuts against the end of the guide post 3021 under the pulling action of the first elastic member 301. When the external connector is not aligned with the connector 101, when the moving platform 2 swings to a certain extent, the moving platform 2 can still achieve the function of automatically disengaging from the guide post 3021.

[0048] In one possible implementation, the mobile platform 2 includes a main body 201 and a connecting seat 202. The main body 201 has an insertion interface 101, and a connecting surface 2011 is formed on the side of the main body 201 near the support platform 4. The connecting seat 202 is detachably connected to the connecting surface 2011. The side of the connecting seat 202 near the support platform 4 is provided with a magnetic connecting position 2021. The connecting position 2021 is provided one-to-one with the guide component 302. The guide post 3021 is magnetically connected to the connecting position 2021. With this type of mobile platform 2, the insertion position of the test plate 1 along the third direction Z can be adjusted by changing the form of the main body 201 or the connecting seat 202, which makes position adjustment easier. In addition, it is not necessary to make the entire mobile platform 2 magnetic, but only the connecting position 2021 on the connecting seat 202 needs to be magnetic. The structure is simple and reliable and easy to manufacture.

[0049] It should be noted that the test board 1 is installed on the main body 201, and the interface 101 of the test board 1 is the same as the interface 101 of the main body 201.

[0050] The number of connecting seats 202 is not limited. It can be that each connecting seat 202 has a connecting position 2021 corresponding to each guide post 3021, or the number of connecting seats 202 can correspond one-to-one with the number of multiple guide posts 3021, with each connecting seat 202 having one connecting position 2021.

[0051] Specifically, there is no limitation on the specific form of the connection position 2021. It can be flat, grooved, or protruding, as long as it can be magnetically connected to the guide post 3021.

[0052] It should be noted that magnetic connection refers to the fact that the direction of the connection position 2021 is opposite to the direction of the end of the guide post 3021, and the two are magnetically attracted to each other to achieve magnetic connection.

[0053] Alternatively, as an alternative implementation, one of the connection position 2021 and the end of the guide post 3021 may be magnetic, while the other may be a metal structure that can be attracted by magnetism, thereby also achieving a magnetic connection.

[0054] Preferably, such as Figure 3 As shown, there are four guide components 302 arranged in a rectangular shape. The connecting seat 202 is set one-to-one with the guide component 302. The main body 201 is provided with a connecting hole 2012. The connecting seat 202 is fixedly connected to the connecting hole 2012 by fasteners.

[0055] Fasteners can be screws, bolts, etc.

[0056] Preferably, such as Figure 1 and Figure 2 As shown, a first connecting structure 2013 is provided on the side of the main body 201 near the bearing platform 4, and a second connecting structure 402 is provided on the side of the bearing platform 4 near the main body 201. One end of the first elastic member 301 is connected to the first connecting structure 2013, and the other end is connected to the second connecting structure 402.

[0057] In one possible implementation, the wall of the connecting position 2021 is a first arc surface 2022 that is recessed in a direction away from the guide post 3021. The end of the guide post 3021 has a second arc surface 3023 for engaging with the first arc surface 2022. The first arc surface 2022 and the second arc surface 3023 engage. When the test plate 1 drives the moving platform 2 to swing under the action of external force, as the first arc surface 2022 and the second arc surface 3023 slide relative to each other, the moving platform 2 will first perform a translational movement. This can avoid stress concentration caused by contact between the connecting position 2021 and the guide post 3021, and also prevent the connecting position 2021 from disengaging from the guide post 3021 too early.

[0058] In one possible implementation, a protrusion 2023 is provided on the first arc surface 2022, and a corresponding recess 3024 is provided on the second arc surface 3023 to accommodate the protrusion 2023. The protrusion 2023 and the recess 3024 cooperate to play a positioning role. When the moving platform 2 swings slightly and resets, the protrusion 2023 and the recess 3024 are misaligned but not completely separated. At this time, the protrusion 2023 and the recess 3024 have the potential to restore their original cooperation state under the action of magnetic force, which can make the moving platform 2 more accurately reset to the initial cooperation position with the guide post 3021.

[0059] It is understood that, as an alternative implementation, the protrusion 2023 may also be a frustum-shaped protrusion, and the recess 3024 may be a frustum-shaped groove.

[0060] Specifically, the protrusion 2023 is a conical protrusion and the recess 3024 is a conical groove. Since the protrusion 2023 is a conical protrusion and the recess 3024 is a conical groove, the reset process of the protrusion 2023 and the recess 3024 can also enable the mobile platform 2 to return to its initial state more quickly.

[0061] Furthermore, there are no restrictions on the specific form of the cone; it can be either a circular cone or a cold cone, and the choice can be made flexibly according to the requirements.

[0062] In one possible implementation, the guide post 3021 includes a guide segment 30211 and a magnetic segment 30212. The guide segment 30211 passes through the swing connector 3022. The magnetic segment 30212 is detachably connected to the end of the guide segment 30211 near the moving platform 2. The end of the magnetic segment 30212 is magnetically connected to the connection position 2021. The segmented guide post 3021 is not only easy to process and manufacture, but also allows for flexible replacement of the specifications and dimensions of the guide segment 30211 and the magnetic segment 30212.

[0063] Specifically, there is no limitation on the connection method between the guide section 30211 and the magnetic section 30212. It can be a threaded connection or a connection through other fastening components. The specific connection method can be flexibly selected.

[0064] In one possible implementation, each guide component 302 further includes a second elastic element 3025, which is located between the moving platform 2 and the support platform 4. The second elastic element 3025 is sleeved on the outside of the guide post 3021 and is used to support the moving platform 2. The second elastic element 3025 can improve the stability of the moving platform 2 and prevent the moving platform 2 from swinging randomly during normal insertion, thereby improving test stability. In addition, the second elastic element 3025 and the first elastic element 301 support the moving platform 2 together. The height of the moving platform 2 can be adjusted by adjusting the length and elastic coefficient of the second elastic element 3025 and the first elastic element 301.

[0065] It is understood that, as an alternative implementation, since the second elastic element 3025 is provided, the guide post 3021 and the swing connector 3022 can also be replaced with a gravity hammer and a pull rope. The gravity hammer is fixedly connected to the moving platform 2 through the pull rope. The gravity hammer passes through the bearing platform 4 and uses its own gravity to reset the moving platform 2 and maintain its initial position.

[0066] Specifically, there is no limitation on the specific form of the second elastic element 3025 and the first elastic element 301. They can be springs, or elastic rubber sleeves, plastic sleeves, etc., which can be selected according to the requirements.

[0067] Preferably, both the first elastic element 301 and the second elastic element 3025 are springs.

[0068] In one possible implementation, the swing connector 3022 is a universal ball bearing. The swing connector 3022 includes a fixed part 30221 and a rotating part 30222. The bearing platform 4 has a through hole 401 for mounting the fixed part 30221. The rotating part 30222 is rotatably disposed in the fixed part 30221 and has a guide hole 30223 for the guide post 3021 to pass through. One end of the second elastic member 3025 abuts against the connecting seat 202, and the other end abuts against the rotating part 30222. This type of guide post 3021 cooperates with the swing connector 3022, which allows the moving platform 2 to move in any direction in space. This not only improves the buffer flexibility of the moving platform 2, but also enables the insertion and removal test device to adapt to the insertion test requirements in any direction in the insertion plane, thereby improving the test flexibility of the device.

[0069] Specifically, since the guide post 3021 passes through the guide hole 30223, the rotation range of the rotating part 30222 in the fixed part 30221 is also limited. When the rotating part 30222 rotates to the point that the guide post 3021 interferes with the fixed part 30221, the guide post 3021 reaches the swing limit position. When the moving platform 2 continues to move under external force, it will separate from the guide post 3021. This type of guide post 3021, in conjunction with the swing connector 3022, can also ensure that the moving platform 2 can stably separate from the guide post 3021.

[0070] In one possible implementation, the side of the connecting seat 202 near the bearing platform 4 is provided with an annular groove 2024. The annular groove 2024 is used to abut against the second elastic member 3025. The annular groove 2024 is arranged along the circumference of the connecting position 2021. After the annular groove 2024 abuts against the second elastic member 3025, it can play a limiting role, preventing the second elastic member 3025 from being displaced at will when it is compressed, and reducing the vibration generated when the moving platform 2 moves.

[0071] The forming method of the annular groove 2024 is not limited. It can be formed by the inward concavity of the surface of the connecting seat 202, or by the annular protrusions spaced apart on the surface of the connecting seat 202.

[0072] In one possible implementation, the insertion and removal test device further includes a fixed platform 5, which includes a connecting column 501 and a fixed plate 502. The fixed plate 502 is located on the side of the support platform 4 away from the moving platform 2. The fixed plate 502 is fixedly connected to the support platform 4 through the connecting column 501. The space between the fixed plate 502 and the support platform 4 forms a clearance space 503. The clearance space 503 is used for the guide column 3021 to pass through. The fixed platform 5 can raise the support platform 4 to a certain height. The clearance space 503 allows the guide column 3021 to freely extend, retract, and swing, preventing the guide column 3021 from interfering with external components.

[0073] It is understood that, as an alternative implementation, the fixed platform 5 can also be a groove-type structure. The fixed platform 5 has a base plate and a side plate surrounding the base plate. The side plate is fixedly connected to the bearing platform 4. The fixed platform 5 and the bearing platform 4 together form an avoidance space 503.

[0074] Furthermore, there are no restrictions on the connection method between the connecting column 501 and the bearing platform 4. It can be welding, bolting, etc., as long as the two can be connected together at the same temperature.

[0075] According to an embodiment of the present invention, in another aspect, a connector testing system is provided, which includes the above-described insertion and removal testing device.

[0076] In one possible implementation, the connector testing system also includes necessary testing devices such as a connector durability testing device, a connector insulation resistance testing device, a connector withstand voltage testing device, a connector contact resistance testing device, and a connector vibration testing device.

[0077] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
