[0002] The working voltage and current of a semiconductor laser are compatible with integrated circuits, so it can be monolithically integrated with them. Therefore, a power supply detector is required for detection during its production. Since most of the performance of the power supply is related to the magnitude of the input current and voltage, the detection operation of the existing power supply detector is as follows: The operator holds the two pole connection posts in both hands and connects them to the positive and negative poles of the power supply respectively, and then detects and records the relevant performance data of the power supply under different currents or voltages by adjusting the magnitude of the input current or the magnitude of the connected voltage.

[0003] However, before or after the existing power supply performance detector is used, it is necessary to take the detector out of the storage box, or place the detector into the storage box and also store the external wiring and the two pole connection posts. The use or storage is relatively cumbersome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a performance detector for a semiconductor laser driving power supply, so as to solve the problem that before and after use, the detector needs to be taken out or put back, and when putting it back, it is also necessary to sort out the external wiring and the two pole connection posts, and the use or storage is relatively cumbersome as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

Detailed Embodiment

[0033] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application.

[0034] As Figures 1 to 6 shown, a semiconductor laser driving power supply performance detector includes a storage box 1 and an inner enclosure 2 fixed in the storage box 1. The inner wall of the inner enclosure 2 and a corner inside the storage box 1 enclose a driving cavity 3, and the outer wall of the inner enclosure 2 and another corner inside the storage box 1 enclose a storage groove 5. The semiconductor laser driving power supply performance detector further includes:

[0035] A wiring storage box 6 slidably sleeved in the storage groove 5. A convex strip is fixedly provided on one side of the top of the wiring storage box 6 close to the inner enclosure 2, and one side of the wiring storage box 6 is slidably sleeved with a through groove 7 provided on the vertical surface of the storage box 1.

[0036] Rotate the lead screw 8 disposed in the storage groove 5. One end of the lead screw 8 is threadedly sleeved with a threaded hole 15 provided on the wiring storage box 6. One end of the lead screw 8 passes through the inner retaining wall 2 and extends into the drive cavity 3. The lead screw 8 is used to drive the wiring storage box 6 to move linearly.

[0037] A drive part 18 disposed in the drive cavity 3 for driving the lead screw 8 to rotate.

[0038] The detector body 4 disposed in the storage box 1.

[0039] The external wiring 9 fixed to the detector body 4. One end of the external wiring 9 is inserted and connected to a sliding wire groove 10 provided on the wiring storage box 6.

[0040] By driving the lead screw 8 to rotate through the drive part 18, the wiring storage box 6 is driven to pass through the through groove 7 and extend out of or retract into the storage groove 5. When using the detector body 4 to detect the semiconductor laser drive power supply, the external wiring 9 can be quickly taken out or quickly stored after detection, without taking out the detector body 4 or storing it in the storage box 1 after detection, and the operation is simple and efficient.

[0041] In this embodiment, the semiconductor laser drive power supply performance detector further includes:

[0042] A guide bar 16 fixed to the inner bottom of the storage groove 5. The top of the guide bar 16 is slidably sleeved with a guide groove 17 provided on the bottom of the wiring storage box 6.

[0043] The axis of the guide bar 16 is parallel to the axis of the lead screw 8, and the guide bar 16 is used to constrain the linear movement state of the guide wiring storage box 6.

[0044] The guide bar 16 and the lead screw 8 cooperate to jointly constrain the moving direction of the wiring storage box 6, so that it can always move linearly along the axial direction of the lead screw 8, avoiding deviation of its moving direction and improving the smoothness of its movement.

[0045] In this embodiment, the semiconductor laser drive power supply performance detector further includes:

[0046] A wire splitting base 11 fixed to one end of the external wiring 9.

[0047] A wire splitting rod 12 relatively fixed to the wire splitting base 11.

[0048] A right-angle seat 13 fixed to one end of the wire splitting rod 12.

[0049] A detection joint 14 fixed to the right-angle seat 13.

[0050] The wire splitting base 11 and the two wire splitting rods 12 enclose a U-shaped clip, and wires are inserted through the wire splitting rods 12.

[0051] One end of the wire passes through the inside of the right-angle base 13 and is electrically connected to the detection connector 14, and the other end of the wire is electrically connected to one end of the external connection wire 9.

[0052] The wire dividing rod 12 is provided to facilitate the division of the two-stage wiring in the external connection wire 9, so that the two-stage wiring can be juxtaposed and independent of each other, and it can also enable the two-stage wiring to be electrically connected to the two detection connectors 14 through two wires respectively, which is convenient for the operator to operate with one hand, and can easily and efficiently adjust the distance between the two detection connectors, expanding its application range, so as to facilitate the detection of semiconductor laser drive power supplies of different sizes.

[0053] In this embodiment, the detection connector 14 is perpendicular to the wire dividing rod 12, and the detection connector 14 is conical as a whole. With such a design, when the operator extrudes the two wire dividing rods 12 to the limit and the free ends of the two wire dividing rods 12 touch each other, a certain safety distance can still be maintained between the two detection connectors 14, avoiding the phenomenon of extreme discharge between the two detection connectors 14 and improving the safety of the detection operation.

[0054] Working principle: By controlling the output end of the driving motor to rotate clockwise, through the power transmission between the spur gear on its output end and the transmission teeth on the lead screw 8, the lead screw is driven to rotate counterclockwise. The rotating lead screw 8 drives the wiring storage box 6 to extend out of the storage groove 5 and makes a part of it pass through the through groove 7. Due to the setting of the upper convex strip, the vertical surface of the wiring storage box 6 opposite to the inner enclosure 2 is larger than the opening of the through groove 7, which can prevent the wiring storage box 6 from completely passing through the through groove 7 until the upper convex strip on the wiring storage box 6 abuts against the outside of the upper edge of the through groove 7. Then the operator can directly take out the wire dividing seat 11 from the wiring storage box 6, and can hold the two wire dividing rods 12 with one hand, and adjust the distance between the free ends of the two wire dividing rods 12 by controlling the pressure of the hand squeezing the two wire dividing rods 12. The operation is simple and efficient. At the same time, when the two wire dividing rods 12 are extruded to the limit and their free ends touch each other, a safe distance can still be maintained between the two detection connectors 14, avoiding the dangerous phenomenon of extreme discharge when the two detection connectors 14 are close to each other and improving the operation safety.

[0055] The above is only the preferred embodiment of the present invention, and the parts not described in the present invention can be realized by adopting or referring to the existing technology. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
