[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] See Figures 1 to 2 The universal lamp-lighting test fixture provided in the first embodiment of this utility model includes a test base 1, on which a plurality of protrusions 11 are provided, and screws 12 are provided on the protrusions 11. A carrier 2 is detachably connected to the test base 1, and the screws 12 are provided between the carrier 2 and the test base 1. The carrier 2 includes a carrier body 21 and a plurality of stops 22 provided on the carrier body 21 for limiting the test product. A slot 23 that mates with the protrusions 11 is provided through the middle of the carrier body 21. The sidewall of the slot 23 extends inward to form a limiting block 231. The screws 12 pass through the slot 23 and connect to the protrusions 11. A snap-fit ​​pin mold connector assembly 3 for lamp-lighting test is provided on one side of the carrier body 21 on the test base 1. A test button assembly 4 for lamp-lighting test is also provided on the test base 1.

[0021] Specifically, the test base 1 is provided with two cylindrical protrusions 11. It is understood that the platform 2 is also provided with two slots 23 that mate with the protrusions 11. The two protrusions 11 can be arranged horizontally or vertically. In this embodiment, the two protrusions 11 are arranged vertically, and the slots 23 on the platform 2 are also arranged vertically. This arrangement makes better use of the internal space of the platform 2. Preferably, the protrusions 11 are cylindrical, and several of the protrusions 11 are arranged in a straight line along the direction close to the snap-fit ​​pin connector assembly 3. When installing the carrier, quick positioning and installation can be achieved through the cooperation of the protrusions 11 and the slots 23, improving the convenience of platform 2 installation. Then, the platform 2 is connected to the test base 1 using screws 12. Next, by sliding the platform 2, adjust the distance between the platform 2 and the snap-fit ​​pin mold connector assembly 3. After adjustment, tighten the screw 12. When the screw 12 abuts against the limiting block 231, press the limiting block 231 to fix the platform 2 on the test base 1. After fixing the platform 2, simply place the test product into the limiting cavity formed by the side of the stop block 22 on the platform 2. Then connect the pins of the test product to the snap-fit ​​pin mold connector assembly 3. Finally, press the test button assembly 4 to perform the lamp test on the test product. If it is necessary to replace the test product with the same pins but different sizes, simply change the platform 2 quickly to perform the lamp test on test products of different sizes, thus improving the versatility of the test base 1.

[0022] Furthermore, the snap-fit ​​pin mold connector assembly 3 includes a snap-fit ​​pin mold connector body and a fixing cover 31 rotatably connected to the snap-fit ​​pin mold connector body; before the lighting test, the pins of the test product need to be inserted into the snap-fit ​​pin mold connector body first, and then the fixing cover 31 is used to press the pins of the test product onto the snap-fit ​​pin mold connector body to prevent them from loosening or falling off during the test.

[0023] See Figure 2 In actual testing, to prevent the tester from directly opening the fixed cover 31 and removing the pins of the test product from the snap-fit ​​connector body after the lamp test is completed without powering off, thus performing a hot-plugging operation, this embodiment uses a hot-plugging prevention locking block 5 on the test base 1 to prevent the operator from performing hot-plugging operations on the test product. Specifically, the platform body 21 is provided with a hot-plugging prevention locking block 5 that cooperates with the fixed cover 31 to form a hot-plugging prevention mechanism for the test product. The hot-plugging prevention locking block 5 is slidably connected to the platform body 21. The internal principle is that when the hot-plugging prevention locking block 5 slides to the position where it is engaged with the fixed cover 31, the snap-fit ​​connector body is energized by pressing the switch at the lower end. When the hot-plugging prevention locking block 5 slides away from the position where it is engaged with the fixed cover 31, the switch at the lower end is turned off, de-energizing the snap-fit ​​connector body, allowing the next step of product pin insertion and removal operations to be performed, thereby avoiding hot-plugging.

[0024] See Figure 1 In this embodiment, the platform body 21 is provided with two material picking ports 25. The two material picking ports 25 are formed by the inward indentation of the platform body 21. By setting the material picking ports 25, it is convenient to pick up the test product. It should be noted that the limiting edge formed by the stop block 22 should fall into the middle of the material picking port 25. This makes it convenient to pick up the test product by touching the side of the test product with your finger when picking up the material.

[0025] Furthermore, the stage body 21 is provided with a reflector 24 for detecting light leakage on the side of the test product. The reflector 24 is rotatably connected to the stage body 21. The reflector 24 is used to check whether there is light leakage on the side adhesive attached to the test product.

[0026] In practical applications, due to the large variety of products and the different corresponding test pins, the snap-fit ​​pin mold connector assembly 3 on the test base 1 is also different. In order to facilitate the management of the test base 1, the platform body 21 is provided with 6. By attaching classification information in 6, it is convenient to find the test base 1 later.

[0027] In summary, the universal lamp-lighting test fixture in the above embodiments of this utility model improves the utilization rate of the test base by making the platform fixed on the test base detachable, which facilitates the replacement of platforms of different sizes; by setting an anti-hot-plug locking block on the test base, it prevents hot-plugging manipulation of the test product during the testing process, thereby improving the product yield; in addition, a reflector is set on the base to check whether there is light leakage on the side adhesive of the test product.
