[0033] The butterfly-shaped laser is a highly stable semiconductor laser with a butterfly package. It is widely used in many high-tech fields such as optical fiber communication, spectral analysis, optical sensing, and medical diagnosis due to its compact volume, high-precision temperature control, and excellent optical performance. This type of laser usually incorporates a semiconductor cooler and a thermistor to ensure stable and accurate laser output under various operating conditions. With its delicate design and reliable performance, it is an essential key component in modern optoelectronic systems.

[0034] Before the butterfly-shaped laser product leaves the factory, it needs to be tested. During the power-on test, strict performance evaluations are carried out, including the detection of key parameters such as contact resistance, insulation resistance, switching speed, and durability, to ensure stable, fast, and safe switching performance in various electrical applications and meet the requirements for highly reliable relays in industrial automation, power system protection, and communication equipment.

[0035] In related technologies, the butterfly-shaped laser has various specifications. The lengths, heights of the power-on fins of different specification butterfly-shaped lasers, and the spacing between each fin are all different. Currently, the existing power-on devices for butterfly-shaped lasers can only meet the testing of a single specification butterfly-shaped laser, with poor general applicability.

[0036] To solve the above problems, the present utility model proposes a power-on device for a butterfly-shaped laser, aiming to solve the problem that the power-on device for a butterfly-shaped laser can only meet the testing of a single specification butterfly-shaped laser and can be applicable to the power-on testing of various different specification butterfly-shaped lasers. Figures 1 to 5 It is a schematic structural diagram of an embodiment provided by the power-on device for the butterfly-shaped laser of the present utility model.

[0037] Please refer to Figures 1 to 5 , the present utility model proposes a power-on device 1000 for a butterfly-shaped laser, which includes a power-on base 1 and a contact power-on structure 2. The power-on base 1 is provided with two sets of tracks 11, and the two sets of tracks 11 are arranged relatively at intervals. The contact power-on structure 2 includes two test components 2a. The two test components 2a are respectively slidably arranged on the two sets of tracks 11 and can approach or move away from each other. Each test component 2a is provided with a plurality of contact parts 21. The plurality of contact parts 21 can move in a direction perpendicular to the power-on base 1, and the contact parts 21 are used for contacting and conducting electricity with the power-on fins 2100 of the butterfly-shaped laser.

[0038] In the technical solution of the present utility model, a power supply device 1000 for a butterfly laser and a testing device are proposed. Among them, the power supply device 1000 for a butterfly laser includes a power supply base 1 and a contact power supply structure 2. The power supply base 1 is provided with two sets of tracks 11 arranged at intervals. The contact power supply structure 2 includes two testing components 2a. The testing components 2a are respectively slidably arranged on the two sets of tracks 11 and can approach or move away from each other. Each testing component 2a is provided with a plurality of contact parts 21, and the plurality of contact parts 21 can move in a direction perpendicular to the power supply base 1. During the testing process, first fix the butterfly laser to be tested on the power supply base 1, and make each power supply fin 2100 of the butterfly laser contact with a contact part 21. Finally, connect the power supply base 1. By adjusting the distance between the two testing components 2a, butterfly lasers with different lengths of power supply fins 2100 can be matched. By adjusting the vertical position of the contact part 21, butterfly lasers with different heights of power supply fins 2100 can be matched, so as to be applicable to the power supply testing of butterfly lasers of different size specifications, improving the general applicability of the device.

[0039] To realize the up and down adjustment of the contact part 21, that is, to adjust the height difference between the contact part 21 and the upper plane of the power supply base 1, the testing component 2a further includes a mounting frame 22 and a mounting rod 23. Specifically, please further refer to Figure 4 , waist-shaped holes extending in a direction perpendicular to the power supply base 1 are respectively provided on both sides of the mounting frame 22. The mounting rod 23 is slidably arranged in the waist-shaped holes, and a plurality of contact parts 21 are arranged on the mounting rod 23. With such a setting, a flexible adjustment mechanism is provided for the height adjustment of the contact part 21, enabling the contact part 21 to adapt to butterfly laser products of different heights. The versatility and adaptability of the testing component 2a are enhanced, allowing the same testing component 2a to be used for laser products of multiple specifications, thereby reducing the need for special testing tools, improving the testing efficiency, reducing the production cost, and making the testing process of the laser more standardized and systematic. In addition, this height-adjustable design also helps to ensure the precise alignment between the laser and the testing component 2a, improving the accuracy and reliability of the testing.

[0040] To limit the mounting rod 23 to ensure that the mounting rod 23 is fixed at any height position in the waist-shaped hole, limiting parts 231 and adjusting parts 232 are respectively provided at both ends of the mounting rod 23. Specifically, please further refer to Figure 4 and Figure 5, the adjusting member 232 is screwed to the mounting rod 23, the limiting member 231 and the adjusting member 232 are both in contact with the mounting frame 22, and the operator can loosen the adjusting member 232, that is, loosen the knob, so that the mounting rod 23 can move up and down in the waist-shaped hole. When the connecting pin 211 of the contact part 21 is in the same height as the powered fin 2100 of the butterfly laser, the adjusting member 232 is locked to fix the mounting rod 23, so as to adapt to products of different specifications, and achieve precise positioning through the screwed adjusting member 232. At the same time, the existence of the limiting member 231 ensures that the height adjustment of the mounting rod 23 in the waist-shaped hole will not exceed the predetermined range, and prevents equipment damage or test errors that may be caused by excessive adjustment. In addition, the abutment design of the limiting member 231 and the adjusting member 232 with the mounting frame 22 enhances the stability and reliability of the overall structure, and ensures that the fixed position of the mounting rod 23 will not be offset due to external force or vibration during the test, thereby improving the accuracy and repeatability of the test. The mounting rod 23 also includes two guide blocks 233, which are respectively located in the two waist-shaped holes. The guide blocks 233 can ensure that the mounting rod 23 moves along the setting direction of the waist-shaped holes, and can also ensure that the horizontal movement error of the mounting rod 23 is controllable.

[0041] In one embodiment of the present invention, in view of the different spacings of the powered fins 2100 of butterfly lasers of different specifications, in order to meet the power-on test requirements of butterfly lasers with powered fins 2100 of different spacings, multiple contact portions 21 are provided with mounting holes, and the mounting rods 23 are passed through the multiple mounting holes. For details, please refer to Figure 4 The inner diameter of the mounting hole is larger than the outer diameter of the mounting rod 23, and multiple contact portions 21 are movably arranged on the mounting rod 23. Correspondingly, the contact portion 21 includes a connecting pin 211 and a lever 212 connected to each other. The mounting frame 22 is formed with a frame opening 24, and the connecting pin 211 is arranged at the frame opening 24. An adjusting groove 25 is formed at the upper part of the frame opening 24. The lever 212 is exposed on the side of the adjusting groove 25 facing away from the frame opening 24. The operator can adjust the spacing between each connecting pin 211 by toggling the lever 212, thereby meeting the test requirements of powered fins 2100 with different spacings.

[0042] In order to keep the connection pin 211 and the butterfly laser in contact, the connection pin 211 is formed with a plug slot 211a. For details, please refer to Figure 4 When testing, each powered fin 2100 of the butterfly laser is plugged into a corresponding plug-in slot 211a. The powered base 1 is formed with a receiving slot 13, which is located between the two sets of tracks 11. The butterfly laser is placed in the receiving slot 13 to fix and limit the butterfly laser.
