[0046] like Figures 1 to 5 As shown, the utility model provides a plug-in test mechanism and a test device, which includes a plug-in test mechanism for plugging in with a spring-type connector. The plug-in test mechanism includes a substrate 10, a pair of components module 20 and a carrier board 40. The pair of components module 20 is arranged on the substrate 10, and the pair of components module 20 includes a PCBA board 222; the carrier board 40 is used to carry an electronic product 100 with a spring-type connector 101. The carrier board 40 is slidably connected to the substrate 10, and the carrier board 40 can move relative to the substrate 10 to enable the PCBA board 222 to be plugged in and connected with the spring-type connector 101.

[0047] By providing a plug-in and unplug test mechanism with a PCBA board 222, when the counterpart module 20 of the plug-in and unplug test mechanism is plugged and connected to the spring-type connector 101, the PCBA board 222 contacts the spring, and the PCBA board 222 replaces the FFC connecting line. The PCBA board 222 is not easily worn during the plug-in and unplug process; the PCBA board 222 has been tested to be plugged and unplugged more than 15,000 times, which effectively ensures the accuracy of the test, saves the cost of replacing the FFC connecting line, eliminates the need for frequent replacement, and improves the test efficiency; by providing a relatively movable substrate 10 and a carrier board 40, the PCBA board 222 and the spring-type connector 101 are driven to perform stable plug-in and unplug operations, thereby realizing signal transmission to comprehensively detect the signal transmission path and achieve the purpose of testing.

[0048] In this embodiment, the hand piece module 20 is arranged at the side edge of the substrate 10, the carrier board 40 and the hand piece module 20 are both located above the substrate 10, the electronic product 100 is placed above the carrier board 40, and the setting height of the electronic connector 101 of the electronic product 100 matches the setting height of the PCBA board 222 of the hand piece module 20.

[0049] To control the movement of the carrier 40, the plug-in test mechanism also includes a driver 50, which is disposed on the base plate 10 and is used to drive the carrier 40 to move. A connector 41 is protruding from the carrier 40, and the driver 50 is connected to the connector 41 and drives the carrier 40 to move via the connector 41. The protruding connector 41 allows the driving force provided by the driver 50 to be effectively transmitted to the carrier 40.

[0050] In this embodiment, a mounting notch is provided on the substrate 10, and a fixing portion 11 is provided on the sidewall of the mounting notch. The driver 50 is connected to the fixing portion 11 and embedded in the mounting notch. The output end of the driver 50 passes through the interior of the fixing portion 11 and connects to the connector 41. Providing the mounting notch on the substrate 10 and embedding the driver 50 within the mounting notch facilitates maintaining the connection between the driver 50 and the carrier 40 while also preventing an excessively large gap between the substrate 10 and the carrier 40.

[0051] Preferably, a snap-in slot is provided on the sidewall of the output end of the driver 50. One end of the connector 41 is fixed to the carrier 40, and the other end of the connector 41 is U-shaped and inserted into the snap-in slot; the connector 41 is generally L-shaped. By providing a snap-in slot at the output end and inserting the connector 41 into the slot, when the output end of the driver 50 moves, the slot wall presses against the connector 41, thereby driving the connector 41 to move.

[0052] To achieve relative movement between the substrate 10 and the carrier 40, the plug-in test mechanism also includes a sliding assembly 30, which is disposed between the substrate 10 and the carrier 40. The sliding assembly 30 includes a slide rail 31 and a slider 32. The slide rail 31 is detachably disposed on the substrate 10, and the slider 32 is detachably disposed on the carrier 40, with the slider 32 slidingly engaging with the slide rail 31. By disposing the sliding assembly 30 between the substrate 10 and the carrier 40, the sliding assembly 30 can support the carrier 40 on the substrate 10, maintaining a certain distance between the substrate 10 and the carrier 40. By providing the detachable slide rail 31 on the substrate 10 and the detachable slider 32 on the carrier 40, the assembly is simplified and maintenance and replacement are facilitated.

[0053] Preferably, to ensure stability during the movement of the carrier plate 40, two sliding assemblies 30 are provided, and the two sliding assemblies 30 are spaced apart. In this embodiment, the driving member 50 is a cylinder, which is provided between the two sliding assemblies 30, and the distance between the two sliding assemblies 30 and the cylinder is equal.

[0054] To ensure accurate installation of the sliding assembly 30, a first positioning slot is provided on the base plate 10, into which the slide rail 31 is positioned; a second positioning slot is provided on the carrier plate 40, into which the slider 32 is positioned. By directly installing the slide rail 31 in the first positioning slot and the slider 32 in the second positioning slot, the relative position of the carrier plate 40 and base plate 10 after installation is restricted, ensuring that the positions of the slider 32 and the slide rail 31 in each set of sliding assemblies 30 correspond.

[0055] In this embodiment, each sliding assembly 30 includes a slide rail 31 and two sliders 32. The slide rail 31 extends along the sliding direction, and the two sliders 32 are arranged at intervals to support the carrier 40 from two positions, further ensuring the stability of the carrier 40 during movement; the carrier 40 can move in a horizontal direction relative to the substrate 10, that is, the sliding direction in this embodiment is a horizontal direction.

[0056] To ensure the proper placement of the electronic product 100, a guide 42 is protruding from the carrier 40 to guide the electronic product 100 onto the carrier 40. A positioning member 43 is also protruding from the carrier 40 to engage with the electronic product 100. The guide 42 allows the electronic product 100 to gradually approach the carrier 40 along the outer surface of the guide 42 until it is placed on the carrier 40. A docking hole is provided on the electronic product 100 to allow the positioning member 43 to be inserted into the docking hole. By providing the positioning member 43 and engaging with the electronic product 100, the relative position of the electronic product 100 and the carrier 40 remains stable during movement of the carrier 40.

[0057] In this embodiment, the guide member 42 is a guide shaft, and the positioning member 43 is a positioning pin. Both the guide shaft and the positioning pin are separately connected to the carrier 40. In other embodiments, the guide shaft and the positioning pin can also be integrally formed on the carrier 40. Preferably, the carrier 40 is also provided with a calibration member 44, which is used to determine the front and back side of the electronic product 100. The provision of the calibration member 44 effectively prevents incorrect placement of the electronic product 100 and improves testing efficiency.

[0058] In this embodiment, an avoidance gap is provided on one side of the carrier board 40, and one side of the spring-type connector 101 provided on the electronic product 100 is flush with the edge of the avoidance gap; the size of the avoidance gap matches the size of the counterpart module 20. During testing, the carrier board 40 and the electronic product 100 are close to the counterpart module 20, and the counterpart module 20 is gradually inserted into the avoidance gap until the spring-type connector 101 and the PCBA board 222 of the counterpart module 20 are plugged in and connected.

[0059] like Figures 6 to 9 As shown, the handpiece module 20 includes a quick-plug component 22 and a fixing plate 21 arranged on the substrate 10. The quick-plug component 22 is arranged on the fixing plate 21. The quick-plug component 22 includes a fixing part 221 and a PCBA board 222. The fixing part 221 is connected to the fixing plate 21. The PCBA board 222 is fixed to the fixing part 221 by screws and nuts. A gold finger 2221 and a quick-plug connector 2222 are provided on the PCBA board 222. When the gold finger 2221 of the PCBA board 222 contacts the spring of the spring-type connector 101, the signal can be conducted.

[0060] In this embodiment, the hand piece module 20 also includes an elastic piece 223 and a stop piece 224. The elastic piece 223 and the stop piece 224 are arranged in a one-to-one correspondence. The elastic piece 223 is embedded in the fixing plate 21 and is located between the fixing piece 221 and the fixing plate 21. The stop piece 224 is passed through the fixing plate 21 and the end portion is threadedly connected to the fixing piece 221 to fix the fixing piece 221 on the fixing plate 21.

[0061] The springs of the spring-type connector 101 are 0.35mm thick and spaced 1mm apart. Existing gold fingers used in FFC cables are made of tin and are approximately 0.05mm thick, which can easily wear out with repeated plugging and unplugging. In this embodiment, the gold fingers 2221 of the PCBA board 222 are made of copper and have a thickness ranging from 0.3mm to 0.5mm. Preferably, the gold fingers 2221 are 0.4mm thick.

[0062] In this embodiment, two quick-connect assemblies 22 are provided, and a counterpart plug-in module for plugging in an SMA connector (Sub Miniature version A) is also provided on the counterpart module 20. One counterpart plug-in module is provided and is located between the two quick-connect assemblies 22. A brake is also provided on the counterpart module 20 to determine whether the carrier 40 has moved into position.

[0063] The following is the specific use process of the plug-in test mechanism:

[0064] First, a worker or robot places the electronic product 100 on the carrier 40. The worker then holds the electronic product 100 against the guide 42, gradually lowering it onto the carrier 40. During the lowering process, the positioning member 43 inserts into the docking hole of the electronic product 100. The placement of the electronic product 100 remains consistent each time.

[0065] Then, the driving component 50 is started, and the plug-in test mechanism is activated, so that the driving component 50 drives the carrier 40 to move, and the carrier 40 and the electronic product 100 move together, and the carrier 40 approaches the counterpart module 20, and the counterpart module 20 is gradually inserted into the avoidance gap of the carrier 40, until the spring of the spring-type connector 101 contacts the gold finger 2221 of the PCBA board 222 of the counterpart module 20 to achieve conduction.

[0066] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
