[0046] As described in the background section, FFC stands for Flexible Flat Cable. It is made by pressing insulating material and flat copper wire together using equipment. It possesses many characteristics such as being flat, flexible, and thin, and is used in various electronic devices to connect different components for data transmission and power supply. In related technologies, a multimeter is typically used to test the continuity of multiple pins in the FFC one by one; this testing method is time-consuming, labor-intensive, and inefficient.

[0047] Reference Figures 1 to 4To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a detection device for detecting the continuity of multiple pins 1210 in a component 1200 to be tested. The detection device includes a visual detection unit 100 and a power supply unit 200. The visual detection unit 100 is electrically connected to a first end of the component 1200 to be tested. The visual detection unit 100 includes multiple visual detection lamps 110, the number of which is the same as the number of pins 1210. The multiple visual detection lamps 110 are respectively electrically connected to the multiple pins 1210 in a one-to-one correspondence. The power supply unit 200 has a positive electrode 210 and a negative electrode 220. One of the positive electrode 210 and the negative electrode 220 is electrically connected to the visual detection unit 100, and the other is electrically connected to a second end of the component 1200 to be tested.

[0048] In this embodiment, the component to be tested 1200 is an FFC (Flexible Flat Cable), and the pins 1210 are leads, which are typically elongated cylindrical or flat structures. The number of pins 1210 is 51. In other embodiments, the number of pins 1210 may be other numbers. The testing device is used for R&D testing of FFC cables, sample identification inspection, IQC (Incoming Quality Control), and abnormal inspection of the entire production process.

[0049] In other embodiments, the component to be tested 1200 may also be an FPC (Flexible Printed Circuit), VGA (Video Graphics Array), or other components. The visual inspection light 110 is an LED (Light-Emitting Diode), and in other embodiments, the visual inspection light 110 may also be a neon light. The power supply is a USB cable or a 5V DC power supply to ensure the normal operation of the inspection process.

[0050] When using the detection device of this application to detect the continuity of multiple pins 1210 in the component under test 1200, multiple visual detection lights 110 are directly electrically connected to the multiple pins 1210 one-to-one. At this time, the multiple visual detection lights 110 can simultaneously react to the continuity of the corresponding pins 1210. If the pin 1210 is in a continuous state, the corresponding visual detection light 110 will light up; if the pin 1210 is in an open state, the corresponding visual detection light 110 will not light up.

[0051] The detection device of this application achieves parallel detection of the continuity of multiple pins 1210 by setting up visual detection lights 110 that are the same number as and electrically connected to each pin 1210. Compared with using a multimeter to test one by one, this detection method can not only connect all pins 1210 for testing at once, but also has visibility and intuitiveness, allowing operators to obtain the continuity information of all pins 1210 at a glance, greatly saving detection time and improving detection efficiency. In addition, in this application, detection can be performed by electrically connecting the first end and the second end of the component to be tested 1200 to the visual detection unit 100 and the power supply unit 200, respectively. This detection method reduces the detection preparation time and further improves detection efficiency compared with the frequent operation of changing the probe connection position and adjusting the range when using a multimeter.

[0052] Reference Figure 1 and Figure 2 In one embodiment, the detection device further includes a first mounting part 300, and a visual detection part 100 is disposed on the first mounting part 300.

[0053] In this embodiment, the first mounting part 300 is a PCBA (Printed Circuit Board Assembly); in other embodiments, the first mounting part 300 may also be an FPC (Flexible Printed Circuit) or a ceramic circuit board. The visual detection lamp 110 can be fixedly mounted on the first mounting part 300 by surface mount technology, through-hole soldering technology, crimping technology, or conductive adhesive bonding technology.

[0054] The first mounting section 300 not only serves to install and fix the visualization detection section 100, but also optimizes the wiring of the visualization detection section 100, avoiding messy distribution of connecting wires and reducing the risk of wire crossing and short circuit.

[0055] Reference Figure 1 and Figure 4 In one embodiment, the detection device further includes a first connecting pad 400, which is disposed on the first mounting portion 300. The first connecting pad 400 is electrically connected to the positive electrode 210 and electrically connected to the visual detection portion 100.

[0056] In this embodiment, the first connecting pad 400 can be fixedly installed on the first mounting part 300 by means of surface mount technology, plug-in soldering technology, crimping technology or conductive adhesive bonding technology.

[0057] The first connection pad 400 not only evenly distributes electrical energy from the positive electrode 210 to multiple visual inspection lamps 110, ensuring the normal operation of each lamp, but also serves as an electrical connection and distribution mechanism. Compared to simple wire connections, the first connection pad 400 enhances the stability of the electrical connection, ensuring the normal operation of the inspection process. Furthermore, the first connection pad 400 can also serve as a test point. By using testing instruments (such as a multimeter) to measure parameters such as voltage and current at the first connection pad 400, it is possible to quickly determine whether the positive terminal of the power supply circuit is functioning normally and whether sufficient electrical energy is being transmitted to the visual inspection unit 100.

[0058] Reference Figures 1 to 5 In one embodiment, the detection device further includes a current limiting part 500 disposed on the first mounting part 300, and the visual detection part 100 is electrically connected to the first connecting pad 400 through the current limiting part 500; the current limiting part 500 includes a plurality of current limiting resistors 510, the number of current limiting resistors 510 is the same as the number of visual detection lamps 110, and the plurality of current limiting resistors 510 are electrically connected to the plurality of visual detection lamps 110 in a one-to-one correspondence.

[0059] In this embodiment, the current-limiting resistor 510 is a surface-mount resistor, which can be fixedly mounted on the first mounting part 300 by means of surface mounting, through-hole soldering, crimping, or conductive adhesive bonding. The visual detection part 100 is electrically connected to the current-limiting part 500, and the current-limiting part 500 is electrically connected to the first connecting pad 400.

[0060] The current-limiting resistor 510 serves two purposes: firstly, it limits the current and divides the voltage, preventing overcurrent from damaging the visual detection lamp 110; secondly, it ensures that each visual detection lamp 110 receives a suitable and relatively stable current, thereby ensuring that the brightness of each visual detection lamp 110 remains consistent.

[0061] Reference Figure 1 and Figure 4 In one embodiment, the detection device further includes a switch 600, which is disposed on the first mounting part 300, and the first connecting pad 400 is electrically connected to the visual detection part 100 through the switch 600.

[0062] In this embodiment, the switch 600 can be any one of a toggle switch, tactile switch, micro switch, or push-button switch, and can be fixedly mounted on the first mounting part 300 using methods such as surface mount technology, through-hole soldering, crimping, or conductive adhesive bonding. The first connecting pad 400 is electrically connected to the switch 600, the switch 600 is electrically connected to the current limiting part 500, and the current limiting part 500 is electrically connected to the visual detection part 100.

[0063] The switch 600 controls the power supply to the detection device. When the device is needed to check the continuity of pin 1210 in the component under test 1200, the switch 600 is closed, allowing current to flow from the positive terminal 210 through the switch to the visualization detection unit 100, activating the visualization detection element and displaying the test results. When the test is finished or the device is no longer needed, the switch 600 is opened to cut off the circuit, stopping power supply to the visualization detection unit 100, avoiding unnecessary energy consumption, and extending the lifespan of the visualization detection element and other circuit components. Furthermore, the switch serves as a safety measure, preventing accidental activation of the detection device and improving its safety and reliability.

[0064] Reference Figures 1 to 4 as well as Figure 6 In one embodiment, the detection device further includes a first connection portion 700, which is disposed on the first mounting portion 300. The first connection portion 700 has a plurality of first connection pins 710, the number of which is the same as the number of visual detection lamps 110. The plurality of first connection pins 710 are electrically connected to the plurality of visual detection lamps 110 in a one-to-one correspondence. The visual detection lamps 110 are used to be electrically connected to the corresponding pins 1210 through the corresponding first connection pins 710.

[0065] In this embodiment, the first connecting part 700 is an FFC-PCB connector. In other embodiments, the first connecting part 700 may also be determined according to the specific type of the component to be tested 1200, and no further restrictions are imposed here. Meanwhile, the first connecting part 700 may be fixedly installed on the first mounting part 300 by means of surface mount technology, plug-in soldering technology, crimping technology or conductive adhesive bonding technology.

[0066] The first connection part 700 not only ensures a precise connection between the visual inspection lamp 110 and its corresponding pin 1210, thus ensuring the accuracy of the inspection, but also makes the connection between the inspection device and the component under inspection 1200 more convenient and reliable. During inspection, the operator can easily connect the pin to the first connection pin 710 with a simple plug-and-play action, greatly improving inspection efficiency and connection stability. Furthermore, if a visual inspection lamp 110 is damaged, the presence of the first connection part 700 facilitates replacement. Maintenance personnel can easily remove the damaged visual inspection lamp 110 by disconnecting it from the first connection pin 710, then install a new visual inspection lamp 110 and reconnect it to the first connection pin 710. This modular connection method eliminates the need for complex rewiring of the entire inspection device's circuitry, reducing maintenance difficulty and cost.

[0067] Reference Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 In one embodiment, the detection device further includes a second mounting portion 800 and a conductive portion 900. The conductive portion 900 is disposed on the second mounting portion 800 and is used to electrically connect the second end of the component to be detected 1200 to one of the positive electrode 210 and the negative electrode 220. The conductive portion 900 has a plurality of conductive elements 910, the number of conductive elements 910 being the same as the number of pins 1210. The plurality of conductive elements 910 are used to electrically connect to the plurality of pins 1210 in a one-to-one correspondence.

[0068] In this embodiment, the second mounting part 800 is a PCBA (Printed Circuit Board Assembly); in other embodiments, the second mounting part 800 may also be an FPC (Flexible Printed Circuit) or a ceramic printed circuit board. The conductive part 900 is electrically connected to the second end of the component to be tested 1200 and to the negative terminal 220, so that the second end of the component to be tested 1200 is electrically connected to the negative terminal 220. The conductive element 910 is a printed circuit, and the conductive element 910 may be fixedly mounted on the first mounting part 300 using surface mount technology, through-hole soldering technology, crimping technology, or conductive adhesive bonding technology; in other embodiments, the conductive element 910 may also be a wire, a zero-ohm resistor, or a metal jumper.

[0069] The first mounting section 300 and the second mounting section 800 used in this application can, on the one hand, separate the first and second ends of the component to be tested 1200, making the wiring clearer and improving the neatness and maintainability of the wiring; on the other hand, they can separate components that generate electromagnetic signals (such as the visual detection lamp 110) from components such as the conductive section 900, reducing the possibility of electromagnetic interference. Furthermore, if the detection device malfunctions, the first mounting section 300 and the second mounting section 800 make it easier for maintenance personnel to locate the fault, reducing the difficulty and cost of repair. In addition, the conductive section 900 also forms a complete detection loop between the detection device and the component to be tested 1200, ensuring the normal operation of the detection process.

[0070] Reference Figure 1 , Figure 3 , Figure 4 as well as Figure 7 In one embodiment, the detection device further includes a second connecting pad 1000, which is disposed on the second mounting portion 800. The second connecting pad 1000 is electrically connected to the negative electrode 220 and to the conductive portion 900.

[0071] In this embodiment, the second connecting pad 1000 can be fixedly installed on the second mounting part 800 by means of surface mount technology, plug-in soldering technology, crimping technology or conductive adhesive bonding technology.

[0072] The second connection pad 1000 not only serves to connect the negative terminal 220 and the conductive part 900, but also enhances the stability of the electrical connection. Furthermore, the second connection pad 1000 can also be used as a test point. By using a testing instrument (such as a multimeter) to measure parameters such as voltage and current at the second connection pad 1000, it is possible to quickly determine whether the negative terminal of the power supply circuit is working properly and whether there is sufficient electrical energy transmitted to the conductive part 900.

[0073] Reference Figure 1 , Figure 3 , Figure 4 as well as Figures 7 to 9 In one embodiment, the detection device further includes a second connection portion 1100, which is disposed on the second mounting portion 800. The second connection portion 1100 has a plurality of second connection pins 1110, the number of which is the same as the number of conductive elements 910. The plurality of first connection pins 710 are electrically connected to the plurality of conductive elements 910 in a one-to-one correspondence. The conductive elements 910 are used to electrically connect to the corresponding pin 1210 through the corresponding second connection pin 1110.

[0074] In this embodiment, the second connecting part 1100 is an FFC-PCB connector. In other embodiments, the second connecting part 1100 may be determined according to the specific type of the component 1200 to be tested, and no further restrictions are imposed here. The second connecting part 1100 may be fixedly mounted on the second mounting part 800 using surface mount technology, soldering, crimping, or conductive adhesive bonding. Furthermore, the conductive element 910 is electrically connected to the corresponding second connecting pin 1110, and the second connecting pin 1110 is electrically connected to the corresponding pin 1210.

[0075] The second connection part 1100 not only ensures a precise connection between the conductive element 910 and the corresponding pin 1210, thus ensuring the accuracy of the test, but also makes the connection between the test device and the component under test 1200 more convenient and reliable. During testing, the operator can stably connect the pin 1210 to the second connection pin 1110 through simple plugging and unplugging actions, greatly improving the test efficiency and connection stability. Furthermore, if a conductive element 910 is damaged, the existence of the second connection part 1100 facilitates replacement. Maintenance personnel can easily remove the damaged conductive element 910 by disconnecting it from the second connection pin 1110, then install a new conductive element 910 and reconnect it to the second connection pin 1110. This modular connection method eliminates the need for complex rewiring of the entire test device's circuitry, reducing maintenance difficulty and cost.

[0076] In summary, implementing the detection device provided in this embodiment has at least the following beneficial technical effects: When using the detection device of this application to detect the continuity of multiple pins 1210 in the component to be tested 1200, multiple visual detection lights 110 are directly electrically connected to the multiple pins 1210 one-to-one. At this time, the multiple visual detection lights 110 can simultaneously react to the continuity of the corresponding pins 1210. If the pin 1210 is in a continuous state, the corresponding visual detection light 110 will light up; if the pin 1210 is in an open state, the corresponding visual detection light 110 will not light up.

[0077] The detection device of this application achieves parallel detection of the continuity of multiple pins 1210 by setting up visual detection lights 110 that are the same number as and electrically connected to each pin 1210. Compared with using a multimeter to test one by one, this detection method can not only connect all pins 1210 for testing at once, but also has visibility and intuitiveness, allowing operators to obtain the continuity information of all pins 1210 at a glance, greatly saving detection time and improving detection efficiency.
