[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0031] References to "one embodiment," "some embodiments," or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0032] Flexible printed circuits (FPCs) and rigid printed circuit board assemblies (PCBAs) fabricated using surface mount technology (SMT) are essential components for a wide range of digital products and electronic devices. To achieve compactness, thinness, and lower costs, FPCs and PCBs are often combined to create a combined circuit board. After production, individual FPCs, PCBAs, and combined FPC and PCB boards undergo functional testing to determine compliance with standards.

[0033] In related technologies, the testing method involves manually plugging the test lead of a test device into the connector on the circuit board under test to connect the test device and the circuit board under test, and then testing the circuit board. In this method, improper insertion and removal of the test lead by the operator can easily damage the connector on the circuit board, causing the circuit board to malfunction, reducing the yield of the circuit board and increasing the cost of disassembling and recycling the circuit board.

[0034] In view of the above problems, the embodiments of the present application provide a plugging and unplugging fixture and a testing device, which aim to solve the technical problem of damage to the connector caused by plugging and unplugging the test line.

[0035] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0036] Please refer to Figures 1 to 3 In a first aspect, an embodiment of the present application provides a plugging and unplugging fixture 1 , comprising a base 11 , a movable platform 12 and a driving assembly 13 .

[0037] The base 11 has a first bearing plane 111, and the first bearing plane 111 includes a circuit board placement area 1111 to be tested; the mobile platform 12 is slidably arranged on the first bearing plane 111, and the mobile platform 12 has a second bearing plane 1221, and the direction of the second bearing plane 1221 is ( Figure 3 F direction in the figure) is inclined toward the direction close to the placement area 1111 of the circuit board to be tested, and the direction of the second bearing plane 1221 is the same as the direction of the first bearing plane 111 ( Figure 3 The angle between the second support plane 1221 and the test line 22 is an acute angle. The second support plane 1221 is used to support the test line 22. The driving component 13 is used to drive the mobile platform 12 to move toward the direction close to the circuit board placement area 1111 to be tested. The driving component 13 is also used to drive the mobile platform 12 to move away from the circuit board placement area 1111 to be tested.

[0038] In the plugging and unplugging fixture 1 provided by the present application, the driving component 13 drives the mobile platform 12 to move back and forth in the distribution direction of the mobile platform 12 and the placement area 1111 of the circuit board to be tested, so that the test line 22 on the second bearing plane 1221 can be close to or away from the placement area 1111 of the circuit board to be tested, so that the test line 22 can be plugged into the connector 31 on the circuit board to be tested, or detached from the above connector 31, to achieve automatic plugging and unplugging of the test line 22, so that the plugging and unplugging action of the test line 22 is more standardized, which can reduce the damage to the connector 31. In addition, due to the orientation of the second bearing plane 1221 ( Figure 3 F direction in the figure) is inclined toward the direction close to the placement area 1111 of the circuit board to be tested, and the direction of the second bearing plane 1221 is the same as the direction of the first bearing plane 111 ( Figure 3 The angle between the test line 22 and the second bearing plane 1221 is an acute angle, so the test line 22 on the second bearing plane 1221 is arranged at an angle so that the end of the test line 22 enters the above-mentioned connector 31 from top to bottom, which can reduce the wear on the connector 31 compared to directly inserting the connector 31.

[0039] It should be noted that the sliding direction of the mobile platform 12 is Figure 3 The X directions in the figure are parallel to each other, and the orientation of the first bearing surface is Figure 3 The driving assembly 13 drives the mobile platform 12 to slide in the X direction to approach the circuit board placement area 1111 to be tested; the driving assembly 13 drives the mobile platform 12 to slide in the direction opposite to the X direction to move away from the circuit board placement area 1111 to be tested. The direction of the second bearing plane 1221 ( Figure 3 The F direction in the figure is tilted toward the direction close to the placement area 1111 of the circuit board to be tested, which means that the direction of the second bearing plane 1221 is tilted toward the X direction, that is, the angle between the direction of the second bearing plane 1221 and the X direction is an acute angle. The angle between the direction of the second bearing plane 1221 and the direction of the first bearing plane 111 is the same as Figure 3 The angles θ in are equal.

[0040] It should be noted that the connector 31 in the related art is mostly a flip-top connector 31, comprising a substrate, a plurality of terminals, and a cover plate that is rotatably mounted on the substrate. The plurality of terminals are sequentially spaced apart on the substrate. The cover plate can be rotated to expose the terminals, so that the FPC can be placed on the terminals or removed from the terminals. The cover plate can also be rotated to cover the terminals, and the cover plate and the substrate together form a limit groove. When the FPC is accommodated in the limit groove, it contacts and electrically connects with the terminals. At the same time, in order to prevent the FPC from detaching from between the cover plate and the terminals, two stoppers are also provided on the substrate. The two stoppers are arranged horizontally at the notches of the limit groove, and the two stoppers are spaced apart in the distribution direction of the terminals. The FPC has a main body and two stoppers. In the distribution direction of the terminals, the two stoppers are respectively arranged on both sides of the main body. In the distribution direction of the terminals, the distance between the two stoppers is less than the distance between the two stoppers, and the distance between the two stoppers is greater than or equal to the width of the main body. Therefore, when the FPC is accommodated in the limiting groove, the stopper can abut the stopper portion to prevent the FPC from being separated from between the cover plate and the terminal.

[0041] The process of plugging the FPC into the connector 31 is as follows: first flip the cover to expose the terminal, then tilt the FPC, and place the FPC on the terminal from top to bottom so that the main body of the FPC contacts the terminal and the stopper is suspended above the terminal, then lay the FPC flat, during which the stopper can avoid the stopper, and then flip the cover to cover the terminal.

[0042] In combination with the above description, in the plug-in fixture 1 of the first aspect of the embodiment of the present application, by tilting the second bearing plane 1221 toward the direction close to the circuit board placement area 1111 to be tested, and setting the angle between the direction of the second bearing plane 1221 and the direction of the first bearing plane 111 to be an acute angle, the test line 22 carried on the second bearing platform can be tilted, so that the process of the mobile platform 12 driving the test line 22 to approach the circuit board placement area 1111 to be tested is consistent with the process of plugging the FPC and the connector 31 in the related art.

[0043] In some embodiments, the angle between the orientation of the second supporting plane 1221 and the orientation of the first supporting plane 111 is 20°±5°.

[0044] In the above embodiment, by limiting the angle between the orientation of the second bearing plane 1221 and the orientation of the first bearing plane 111 to 20°±5°, the process of the mobile platform 12 driving the test line 22 to approach the circuit board placement area 1111 to be tested can be more consistent with the process of plugging the FPC and the connector 31 in the related art.

[0045] It is understood that after the circuit board 3 under test is placed in the circuit board placement area 1111, since the circuit board 3 under test and the connector 31 are both at a certain height, there will be a certain distance between the connector 31 on the circuit board 3 under test and the first bearing plane 111. In order to facilitate the placement of the test lead 22 on the connector 31, the test lead 22 carried on the second bearing plane 1221 needs to be at a certain height relative to the first bearing plane 111 (i.e., the test lead 22 is located above the first bearing plane 111 in the Z direction).

[0046] Please refer to Figure 3 In some embodiments, the mobile platform 12 includes a sliding portion 121 and a supporting portion 122. In the direction of the first supporting plane 111 (the Z direction in the figure), the sliding portion 121 and the supporting portion 122 are distributed sequentially. The sliding portion 121 is slidably disposed on the first supporting plane 111, and the second supporting plane 1221 is disposed on the supporting portion 122. In the direction close to the circuit board placement area 1111 to be tested (the X direction in the figure), the end of the second supporting plane 1221 is flush with the sliding portion 121 or protrudes from the sliding portion 121.

[0047] In the above embodiment, the carrying portion 122 has a certain height relative to the first carrying plane 111, and the second carrying plane 1221 is set on the carrying portion 122, so the test line 22 carried on the second carrying plane 1221 also has a certain height relative to the first carrying plane 111, which facilitates the test line 22 to be placed from top to bottom on the connector 31 in the circuit board 3 to be tested.

[0048] And because the end of the second bearing plane 1221 is flush with the sliding portion 121 in the direction close to the placement area 1111 of the circuit board to be tested, or the end of the second bearing plane 1221 protrudes from the sliding portion 121, the sliding portion 121 can be prevented from interfering with the test line 22 carried on the second bearing plane 1221, thereby not affecting the connection of the test line 22 to the connector 31.

[0049] Please refer to Figure 2 and Figure 3 In some embodiments, the plugging and unplugging fixture 1 further includes a positioning member 14 , which is disposed on the first bearing plane 111 , and is located between the circuit board placement area 1111 to be tested and the sliding portion 121 .

[0050] In the above embodiment, the positioning member 14 can stop the movable platform 12 to prevent the positioning member 14 from moving too far toward the circuit board placement area 1111 to collide with the circuit board 3 to be tested placed on the circuit board placement area 1111, thereby reducing damage to the circuit board 3 to be tested.

[0051] Furthermore, when the circuit board 3 to be tested is placed in the circuit board placement area 1111 , the positioning member 14 can also assist in positioning the circuit board 3 to be tested.

[0052] In some embodiments, a first slide groove is provided on the base 11, and at least a portion of the mobile platform 12 can be slidably mounted in the first slide groove; or, a second slide groove is provided on the mobile platform 12, and at least a portion of the base 11 can be slidably mounted in the second slide groove.

[0053] Please refer to Figure 1 In the above embodiment, the extension direction of the first chute (not shown in the figure) and the second chute (not shown in the figure) is parallel to the distribution direction of the mobile platform 12 and the placement area 1111 of the circuit board to be tested (i.e., the X direction in the figure). Through the above arrangement, the first chute and the second chute both play a guiding role in the sliding of the mobile platform 12, not only allowing the mobile platform 12 to slide more stably, but also preventing the sliding platform from tilting in a direction deviating from the sliding direction (i.e., tilting in a direction parallel to the Y direction), thereby preventing the test line 22 supported on the second supporting surface from tilting in a direction parallel to the Y direction.

[0054] Please refer to Figure 4 In some embodiments, the driving assembly 13 includes a connecting seat 131, a first connecting rod 132, a second connecting rod 133 and a push rod 134. The connecting seat 131 is set on the base 11. The push rod 134 can slide through the connecting seat 131, and one end of the push rod 134 is connected to the moving platform 12, and the other end of the push rod 134 is rotatably connected to the first connecting rod 132, the second connecting rod 133 is rotatably connected to the connecting seat 131, and the first connecting rod 132 and the second connecting rod 133 are rotatably connected.

[0055] In the above embodiment, the second connecting rod 133 is rotatably connected to the connecting seat 131 around the first rotating shaft 136, the second connecting rod 133 is rotatably connected to the first connecting rod 132 around the second rotating shaft 137, and the first connecting rod 132 is rotatably connected to the push rod 134 around the third rotating shaft 138. In the X direction in the figure, the position of the first rotating shaft 136 is fixed, and the positions of the second rotating shaft 137 and the third rotating shaft 138 are variable.

[0056] By rotating the second connecting rod 133, the position of the second rotating shaft 137 in the X direction can be changed. Since the position of the first rotating shaft 136 is fixed, the position of the third rotating shaft 138 in the X direction will change accordingly, so that the position of the push rod 134 in the X direction changes, so that the push rod 134 can push the movable platform 12 in the X direction.

[0057] Please refer to Figure 4In some embodiments, the second connecting rod 133 includes a rotating portion 1331 and a hand-held portion 1332, the rotating portion 1331 has a first end and a second end relative to each other, the first end is rotatably connected to the connecting seat 131, the second end is rotatably connected to the first connecting rod 132, and the hand-held portion 1332 is connected to the rotating portion 1331.

[0058] Through the above arrangement, the hand-held portion 1332 facilitates the operator to push the second connecting rod 133 to rotate.

[0059] Please refer to Figure 4 In some embodiments, the driving assembly 13 further includes a handle 135 , which is connected to the handheld portion 1332 .

[0060] Through the above arrangement, the hand-held portion 1332 can be extended to facilitate the operator's grip.

[0061] In order to achieve the above-mentioned purpose, the technical solution adopted in the second embodiment of the present application is: a testing device, including a testing mechanism and the plugging and unplugging fixture 1 of the above-mentioned first embodiment.

[0062] The testing mechanism includes a testing circuit board 21 and a testing line 22 . The testing line 22 is attached to the second supporting plane 1221 , and the end of the testing line 22 close to the circuit board placement area 1111 protrudes from the second supporting plane 1221 . The testing line 22 is electrically connected to the testing circuit board 21 .

[0063] By applying the plugging and unplugging fixture 1 of the first embodiment to a test device, the test device can reduce damage to the connector 31 on the circuit board 3 to be tested when testing the circuit board 3 to be tested.

[0064] The test circuit board 21 is used to collect and analyze data such as voltage, circuit, capacitance, etc. of test points on the circuit board 3 to be tested.

[0065] In some embodiments, the testing mechanism further includes a display 23 , which is electrically connected to the testing circuit board 21 .

[0066] The display 23 can display the test data collected by the test circuit board 21 and the results of the analysis, so that the operator can more intuitively judge whether the circuit board 3 to be tested meets the standards.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
