[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0024] like Figures 1 to 4 As shown, the utility model provides a specific embodiment of a power-on test device.

[0025] A power-on test device is used for power-on test of an optical amplifier. A PIN pin is provided at one end of the optical amplifier. Figure 1 and Figure 2 The power-on test device includes a spring carrier 1, a test board 2, a first fixing component 3 and a second fixing component 4; a detection slot 11 and a spring clip 12 are provided on the spring carrier 1, and the spring clip 12 is electrically connected to the test board 2.

[0026] The optical amplifier is placed in the detection slot 11 so that the PIN pin extends into the spring clip 12; the first fixing component 3 is arranged on both sides of the spring clip 12, and the first fixing component 3 can be rotated to press or move away from the spring clip 12; the second fixing component 4 is arranged on both sides of the detection slot 11, and the second fixing component 4 can be rotated to press or move away from the optical amplifier in the detection slot 11.

[0027] Specifically, refer to Figure 1 and Figure 2 The optical amplifier module generally includes a shell part and a PIN pin part that needs to be powered on; the power-on test device in this embodiment is mainly used to perform power-on test on the optical amplifier; a test circuit is arranged on its test board 2 for detecting various working performances of the optical amplifier; the spring clip carrier 1 is mainly used to place the optical amplifier and power on the optical amplifier, and a detection slot 11 is arranged on the spring clip carrier 1 for accommodating the shell part of the optical amplifier module. A spring clip clip 12 is also arranged on the spring clip carrier 1, and the spring clip clip 12 is arranged at one end of the detection slot 11 and is electrically connected to the test board 2. When the optical amplifier is placed in the detection slot 11, the PIN pin at one end of the optical amplifier can extend into the spring clip clip 12, and the electrical connection between the optical amplifier and the test board 2 is realized by contacting with the spring clip clip 12, thereby realizing the power-on test.

[0028] Among them, reference Figure 2 The spring clip 12 can be a copper sheet with elastic force, or other conductive sheets with elastic force; a plurality of mutually insulated springs are arranged on the spring carrier 1 to be connected with different PIN pins in the optical amplifier and realize power supply.

[0029] Further, refer to Figure 2 The first fixing component 3 is mainly used to compress the spring clip 12. When the PIN at one end of the optical amplifier is inserted into the spring clip 12, the first fixing component 3 is rotated and moved toward the spring clip 12 and the spring clip 12 is compressed, so that the spring clip 12 is fully in contact with the PIN pin, thereby performing a stable power-on test.

[0030] Further, refer to Figure 2The second fixing component 4 is mainly used to press the shell part of the optical amplifier. When the optical amplifier is placed in the detection slot 11, the second fixing component 4 is rotated and moved toward the detection slot 11 to press the optical amplifier in the detection slot 11 to fix the optical amplifier and make the power-on test more stable.

[0031] The existing power-on test contact methods of optical amplifier modules are sleeve type or lower probe type; the sleeve type is difficult to operate, and the PIN pin and the sleeve need to correspond one by one, and there is no clamping force, and the dimensional tolerance of the PIN pin itself cannot be compatible. For larger PIN pins, there is a risk of appearance damage during the plug-in process; for smaller PIN pins, electric sparks are easily generated in the absence of sufficient contact, posing a safety hazard; the lower probe type is simpler to operate than the sleeve type, but the lower probe and the PIN pin are in point contact, the contact resistance is large, and there is a risk of data distortion during testing.

[0032] In this embodiment, a powered test device is designed, including a spring clip carrier 1, a test board 2, a first fixed component 3 and a second fixed component 4; a detection slot 11 and a spring clip clamp 12 are provided on the spring clip carrier 1, and the spring clip clamp 12 is electrically connected to the test board 2. When the optical amplifier is placed in the detection slot 11, its PIN pin can be extended into the spring clip clamp 12; by rotating the first fixed component 3, the spring clip clamp 12 can be pressed and the spring clip clamp 12 can be fully contacted with the PIN pin, thereby providing better compatibility with the dimensional tolerance of the PIN pin itself; by rotating the second fixed component 4, the shell part of the optical amplifier can be rotated and pressed to make the detection more stable; when the optical amplifier detection is completed, by rotating the first fixed component 3 and the second fixed component 4, the optical amplifier can be quickly disassembled, which effectively reduces the material replacement time and improves the detection efficiency.

[0033] In one embodiment, reference Figure 3 The first fixing component 3 includes a first pressing block 31 and a first fastener 32. The first pressing block 31 is arranged on one side of the spring clip 12, and the first pressing block 31 can be rotated to press or move away from the spring clip 12. The first fastener 32 is arranged on the other side of the spring clip 12, and the first fastener 32 can be rotated to press or move away from the first pressing block 31.

[0034] Specifically, refer to Figure 3, mounting seats are provided on both sides of the spring clip 12 on the spring clip carrier 1, and the first pressing block 31 is provided on the mounting seat on one side of the spring clip 12. The first pressing block 31 can rotate relative to the corresponding mounting seat so that the first pressing block 31 rotates relative to the spring clip 12. When the optical amplifier is placed in the detection slot 11 and its PIN foot extends into the spring clip 12, the first pressing block 31 is rotated so that the first pressing block 31 covers the spring clip 12, and the spring clip 12 is pressed so that the spring clip 12 is fully in contact with the PIN foot on the optical amplifier.

[0035] Further, refer to Figure 3 The first fastener 32 is arranged on the mounting seat on the other side of the spring clip 12, and the first fastener 32 can also rotate relative to the spring clip carrier 1. When the first pressing block 31 covers the spring clip 12 and presses the spring clip 12, the first fastener 32 is rotated and pressed on the first pressing block 31 to further reinforce and further improve the contact stability between the spring clip 12 and the PIN pin of the optical amplifier.

[0036] In one embodiment, reference Figure 3 One end of the first pressing block 31 is connected to the spring carrier 1 , and the other end of the first pressing block 31 is provided with a first connecting portion 311 for connecting to the first fastener 32 .

[0037] Specifically, refer to Figure 3 Since the first pressing block 31 is rotatably connected to the spring carrier 1, when the first pressing block 31 covers the spring clip 12, the first pressing block 31 is easily lifted up under the action of the rebound force of the spring clip 12, which easily makes the contact between the spring clip 12 and the PIN pin of the optical amplifier not comprehensive. By setting the first connecting portion 311, the other end of the first pressing block 31 can be fixed with the first fastener 32 for secondary clamping, which can effectively improve the clamping force of the first fixing component 3 and further improve the contact stability between the spring clip 12 and the PIN pin of the optical amplifier.

[0038] In one embodiment, reference Figure 3 The first fastener 32 includes a first mounting end 321 and a first clamping end 322. The first mounting end 321 is connected to the spring carrier 1. When the first fastener 32 rotates and clamps the first clamping block 31, the first mounting end 321 is inserted into the first connecting portion 311, and the first clamping end 322 is against the upper surface of the first fastener 32.

[0039] Specifically, refer to Figure 3The first mounting end 321 and the first clamping end 322 are both cylindrical, and the diameter of the first mounting end 321 is smaller than the diameter of the first clamping end 322. When the first fastener 32 rotates, the first mounting end 321 can gradually pass through the first connecting portion 311 and then be stuck in the first connecting portion 311. The first clamping end 322 can directly cover the upper surface of the first pressing block 31 and press the first pressing block 31 to achieve secondary clamping of the spring clip 12, thereby increasing the contact area between the spring clip 12 and the PIN foot, making the contact between the spring clip 12 and the PIN foot more comprehensive and stable.

[0040] In one embodiment, reference Figure 3 The second fixing assembly 4 includes a second pressing block 41 and a second fastener 42. The second pressing block 41 is arranged on one side of the detection groove 11. The second pressing block 41 can be rotated to press or move away from the optical amplifier in the detection groove 11. The second fastener 42 is arranged on the other side of the avoidance groove. The second fastener 42 can be rotated to press or move away from the second pressing block 41.

[0041] Specifically, refer to Figure 3 , mounting seats are provided on both sides of the detection slot 11 on the spring-clip carrier 1, and the second pressing block 41 is provided on the mounting seat on one side of the detection slot 11. The second pressing block 41 can rotate relative to the corresponding mounting seat so that the second pressing block 41 rotates relative to the detection slot 11. When the optical amplifier is placed in the detection slot 11 and its PIN foot extends into the spring-clip clip 12, the second pressing block 41 is rotated so that the second pressing block 41 covers the upper surface of the housing of the optical amplifier and presses the housing to fix the body of the optical amplifier, thereby improving the stability and accuracy of the detection.

[0042] Further, refer to Figure 3 The second fastener 42 is arranged on the mounting seat on the other side of the detection slot 11, and the second fastener 42 can also rotate relative to the spring carrier 1. When the second pressure block 41 covers the housing of the optical amplifier and presses the housing, the second fastener 42 is rotated and pressed on top of the second pressure block 41 to further reinforce and further improve the stability and accuracy of the detection.

[0043] In one embodiment, reference Figure 3 One end of the second pressing block 41 is fixed to the spring carrier 1 , and the other end of the second pressing block 41 is provided with a second connecting portion 411 for connecting to the second fastener 42 .

[0044] Specifically, refer to Figure 3Since the second pressing block 41 is movably connected to the spring carrier 1, when the first pressing block 31 covers the housing of the optical amplifier, its pressing force is insufficient, and it is difficult to prevent the optical amplifier from moving during the detection process. The movement of the optical amplifier is likely to affect the connection between the PIN foot and the spring clip 12, and easily affect the stability of the detection. By providing the second connecting portion 411, the other end of the second pressing block 41 can be fixed with the second fastener 42 for secondary clamping, which can effectively improve the clamping force of the second fixing component 4 and further improve the stability of the detection.

[0045] In one embodiment, reference Figure 3 The second fastener 42 includes a second mounting end 421 and a second clamping end 422. The second mounting end 421 is connected to the spring carrier 1. When the second fastener 42 rotates and clamps the second clamping block 41, the second mounting end 421 is inserted into the second connecting portion 411, and the second clamping end 422 is against the upper surface of the second fastener 42.

[0046] Specifically, refer to Figure 3 The structure of the second fastener 42 is the same as or similar to that of the first fastener 32. The second mounting end 421 and the second clamping end 422 on the second fastener 42 are also cylindrical, and the diameter of the second mounting end 421 is smaller than the diameter of the second clamping end 422. When the second fastener 42 rotates, the second mounting end 421 can gradually pass through the second connecting portion 411 and then be inserted into the second connecting portion 411. The second clamping end 422 can directly cover the upper surface of the second pressing block 41 and press the second pressing block 41, thereby realizing secondary clamping of the housing of the optical amplifier, and making the detection more stable.

[0047] In one embodiment, reference Figure 4 The power-on test device also includes a base 5 , and the test board 2 is fixed on the base 5 .

[0048] Specifically, refer to Figure 4 The base 5 is mainly used to install the test board 2 and support the test board 2 to prevent the test board 2 from being worn by the outside world. A plurality of fixing columns are arranged on the base 5, and the plurality of fixing columns are evenly distributed around the test board 2 to achieve uniform support and fixation of the test board 2. A plurality of fixing holes are respectively arranged around the test board 2 corresponding to the positions of the plurality of fixing columns. By inserting the fixing columns into the fixing holes and fixing them, the test board 2 can be stably installed on the base 5. Since the fixing columns have a certain height, sufficient avoidance space can be provided for the components on the bottom surface of the test board 2, thereby preventing the components from being worn.

[0049] In one embodiment, reference Figure 4 The power-on test device is also provided with a support block 6 for placing the pigtail.

[0050] Specifically, refer to Figure 4 The power-on test device is also provided with a support block 6 for placing a pigtail.
