DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , a five-color test fixture in this embodiment includes a test fixture body 1 and a plurality of test positions 3. Each test position 3 is provided with an independently controllable indicator light 2, and a detection and heat dissipation mechanism is arranged outside the test fixture body 1.

[0023] Embodiment 1. The detection heat dissipation mechanism includes a plurality of indicator lights 2 fixedly installed outside the test fixture body 1, and a plurality of test positions 3 are fixedly installed on the top of the test fixture body 1. The number of indicator lights 2 is ten. The indicator lights 2 can be displayed individually and are arranged side by side outside the test fixture body 1, which helps to conduct detection more intuitively.

[0024] Among them, metal pins 4 are arranged on the top of the test positions 3. The number of test positions 3 and metal pins 4 is ten. The test positions 3 and metal pins 4 are evenly arranged on the top of the test fixture body 1, which is convenient for more effective detection. A heat conduction base 5 is fixedly installed at the bottom of the test fixture body 1. A heat dissipation frame 6 is movably connected to the outside of the heat conduction base 5. A number of ventilation holes are provided inside the heat dissipation frame 6, and the ventilation holes are evenly arranged inside the heat dissipation frame 6, which helps to conduct efficient ventilation.

[0025] In this embodiment, a heat dissipation plate 7 that fits the heat conduction base 5 is fixedly installed on the inner wall of the heat dissipation frame 6. A heat dissipation fan 8 is fixedly installed inside the heat dissipation frame 6. Wires 9 extending to the outside are provided inside the test fixture body 1 and the heat conduction base 5.

[0026] Embodiment 2. A disassembly and assembly component is arranged on the top of the heat dissipation frame 6. The disassembly and assembly component includes two mounting boxes 10 fixedly installed on the top of the heat dissipation frame 6. A return spring 11 is fixedly installed inside the mounting box 10. A movable plate 12 slidably connected to the mounting box 10 is fixedly installed on one side of the return spring 11. Limit slots are provided at the top and bottom of the mounting box 10. The movable plate 12 is slidably connected to the mounting box 10 through the limit slots, which helps to limit the movable plate 12 and is convenient for stable movement.

[0027] Among them, a movable rod 13 extending to the outside of the mounting box 10 is fixedly installed on one side of the movable plate 12. An activity slot is provided on one side of the mounting box 10. The movable rod 13 is movably connected to the mounting box 10 through the activity slot, which helps the movable rod 13 to move. A pull ring 14 is fixedly installed on one side of the movable rod 13.

[0028] In this embodiment, a limit pin 15 inserted into the heat conduction base 5 is fixedly installed on the side of the movable plate 12 away from the movable rod 13. Slots are provided on the left and right sides of the heat conduction base 5. The limit pin 15 is inserted into the heat conduction base 5 through the slots, which helps to insert, fix and disassemble the heat dissipation frame 6.

[0029] It should be noted that for this five-color test fixture, through the provided heat detection mechanism, the function of the metal pins 4 and the indicator light 2 can be used to determine whether the circuit of the lamp beads is normal. The heat conduction seat 5 and the heat spreader 7 can conduct heat quickly. Under the air outlet of the cooling fan 8, the temperature on the heat spreader 7 and the heat conduction seat 5 can be reduced, thereby cooling the test fixture body 1, which helps to increase the service life of the device. The function of the pull ring 14, the movable rod 13, the movable plate 12 and the return spring 11 can drive the limit pin 15 to expand and contract, facilitating the insertion and fixation or detachment and disassembly of the limit pin 15 to the heat conduction seat 5, which is convenient for maintenance and replacement and increases flexibility.

[0030] The working principle of the above embodiment is as follows:

[0031] For this five-color test fixture, the metal pins 4 are brought into contact with one end of the lamp beads to be tested, and the wiring 9 is inserted into the computer test terminal. This structure adopts a separate single empty color system and can complete the optoelectronic parameter tests of five colors. When short circuit, open circuit or other situations occur in the product, the indicator light 2 will go out, thereby judging the quality of the product lamp beads, and the reading can be observed on the computer terminal. At the same time, during the testing process, since the test fixture body 1 is always powered on for testing, a large amount of heat will be generated. At this time, the heat can be transferred to the inside of the heat conduction seat 5 and transferred through the heat conduction seat 5, and the heat is transferred to the heat spreader 7. At this time, the cooling fan 8 can be started, and the cooling fan 8 starts to blow air and blows air towards the heat spreader 7, which can take away the heat on the heat spreader 7 and the heat conduction seat 5, thereby dissipating heat from the heat conduction seat 5 and dissipating heat from the entire device, which helps to increase the service life of the device;

[0032] After the heat dissipation is completed, the pull ring 14 and the movable rod 13 can be pulled. The pull ring 14 drives the movable rod 13 and the movable plate 12 to move. The movable plate 12 moves to compress the return spring 11, and at the same time drives the limit pin 15 to disengage from the inside of the heat conduction seat 5 and no longer be inserted and fixed, so that the heat dissipation frame 6 can be disassembled. Similarly, the return spring 11 can be used to reset and drive the limit pin 15 to be inserted into the inside of the heat conduction seat 5 again, and then the reinstallation and fixation can be carried out, which helps to improve the flexibility and practicality of the device.
