DETAILED DESCRIPTION

[0030] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0031] The embodiments of the present application can be applied to circuit testing of lasers, including semiconductor lasers, laser amplifiers, narrow linewidth lasers, pulsed laser amplifiers, and the like.

[0032] like Figure 1 As shown, this embodiment provides a power supply fixture for laser testing, comprising an upper clamp 1, a lower clamp 2 and a movable connecting component, wherein the movable connecting component is used to drive the lower surface of the front part of the upper clamp 1 and the upper surface of the front part of the lower clamp 2 to maintain a tendency to fit each other; the upper surface of the upper clamp 1 is provided with a first power connection component for electrically connecting to an external power supply, and the lower surface of the front part of the upper clamp 1 is provided with a second power connection component for electrically connecting to an electrical device, and the first power connection component and the second power connection component are electrically connected, wherein the second power connection component includes a plurality of second power connection protrusions 8, and the second power connection protrusions 8 are all telescopically adjustable relative to the upper clamp 1.

[0033] In this embodiment, the upper clip 1 and the lower clip 2 are connected by a movable connecting component, which drives the lower surface of the front part of the upper clip 1 and the upper surface of the front part of the lower clip 2 to maintain a tendency to fit each other, thereby fixing the electrical device; the first power connection component is connected to the external power supply and transmits electricity to the second power connection component, and the second power connection component then transmits electricity to the electrical device to complete the power supply; the second power connection component is telescopically adjustable in the direction facing the lower clip, and can be adjusted to different lengths according to the electrical devices, adapting to electrical devices with height differences, so that the power supply is stable.

[0034] refer to Figure 1 The first power connection component includes a plurality of first power connection protrusions 7 protruding from the upper surface of the upper clip 1.

[0035] The first electrical connection component is used to connect external wires. The first electrical connection protrusion 7 is structured at a certain height from the upper surface of the upper clip 1 to facilitate the insertion of external wires. The first connection protrusion 7 can be directly plugged into an external wire and can be connected to the external wire by simply plugging and unplugging, which is simple to operate and convenient to use.

[0036] like Figure 3 As shown, the first electrical connection protrusions 7 each include a longitudinal portion 701 and an inclined portion 702. The longitudinal portion 701 is connected to the upper clamping plate 1 and protrudes relative to the upper surface of the upper clamping plate 1. The inclined portion 702 is connected to the upper end of the longitudinal portion 701 and is inclined relative to the longitudinal portion 701. The inclined portions 702 of multiple first electrical connection protrusions 7 face the same direction.

[0037] When connected to an external power source, the power plug or other power connection components are correspondingly plugged into the inclined portion 702. The inclined setting of the inclined portion 702 makes it difficult for the power plug to be disengaged. At the same time, the longitudinal portion 701 allows a plugging depth between the power plug and the first power connection protrusion 7, thereby improving the connection strength.

[0038] In order to increase the contact area with the external power source, the first power contact protrusions 7 are arranged in parallel along the width direction of the upper clip 1 .

[0039] In this embodiment, the first power connection protrusion 7 is used to connect to an external power source. The first power connection protrusion 7 is arranged parallel to the width direction of the upper clip 1, thereby increasing the contact area between the first power connection component and the external power source and achieving a better power supply effect.

[0040] like Figure 2 As shown, the second electrical contact protrusion 8 includes an upper connecting portion 802, an elastic member and a lower connecting portion 801 that are electrically connected to each other. The upper connecting portion 802 is connected to the upper clip 1, and the lower connecting portion 801 is telescopically connected to the upper connecting portion 802 through the elastic member.

[0041] When the power supply clamp is subjected to force, the second power connection protrusion 7 is connected to the electrical device, the upper connecting part 802 is fixed, and the lower connecting part 801 is stretched to an appropriate length by the elastic parts arranged on the upper connecting part 802 and the lower connecting part 801, thereby clamping the electrical device. The length of the lower connecting part 801 can be adjusted according to the shape of the electrical device and is compatible with power supplies of different heights.

[0042] Furthermore, a groove 804 is provided on one side of the upper connecting portion 802, and the elastic member is provided in the groove 804, with one end of the elastic member connected to the bottom surface of the groove 804 and the other end connected to the lower connecting portion 801. The elastic member is configured as a spring 803.

[0043] In this embodiment, the upper connecting part 802 and the lower connecting part 801 are connected by an elastic member. Specifically, the elastic member is configured as a spring 803. The spring 803 is arranged inside the upper connecting part 802, which saves space for the power supply clamp and can accommodate larger and more diverse electrical devices. At the same time, it can prevent the spring 803 from being worn and increase its service life.

[0044] Preferably, in order for the spring 803 to be completely disposed inside the upper connecting portion 802 , the free length of the spring 803 is no greater than the depth of the groove 804 .

[0045] like Figure 1 As shown, the second electrical contact protrusions 8 are arranged in parallel along the width direction of the upper clip 1.

[0046] The second power connection protrusions 8 are arranged parallel to the short axis direction of the upper clip 1, which helps the second power connection component to obtain the largest contact area with the electrical device and obtain a better power supply effect; and the second power connection protrusions 8 are arranged parallel to the width direction of the upper clip 1, making it easier to electrically connect the first power connection component and the second power connection component.

[0047] In specific implementation, the movable connecting component includes a rotating shaft 5 and a torsion spring 6. A pair of upper connecting plates 3 are extended downward from the rear part of the upper clip 1, and a pair of lower connecting plates 4 are extended upward from the rear part of the lower clip 2. The rotating shaft 5 passes through the overlapping upper connecting plates 3 and lower connecting plates 4 to enable the upper clip 1 and the lower clip 2 to be rotationally connected. The torsion spring 6 is sleeved on the rotating shaft 5, and one end of the torsion spring 6 abuts against the lower surface of the upper clip 1, and the other end abuts against the lower surface of the lower clip 2.

[0048] The rotating shaft 5 connects the upper clip 1 and the lower clip 2 by passing through the overlapping upper connecting piece 3 and the lower connecting piece 4, so that the upper clip 1 and the lower clip 2 are rotatably connected. A torsion spring 6 is mounted on the rotating shaft 5. One end of the torsion spring 6 abuts against the lower surface of the upper clip 1 and the other end abuts against the upper surface of the lower clip 2. This causes the front of the upper clip 1 and the front of the lower clip 2 to tend to fit together, thereby securing the electrical device. In some embodiments, the movable connector can also be implemented using a threaded assembly, a magnetic assembly, etc., so as to drive the front of the upper clip and the lower clip to have a tendency to fit together.

[0049] During operation, the power supply clamp is composed of an upper clamp 1, a lower clamp 2, a rotating shaft 5 and a torsion spring 6. The two clamps are rotatably connected. When the rear ends of the upper and lower clamps are pressed, the front ends of the upper and lower clamps are opened, and the electrical components are placed in. When the pressing end is released, one end of the torsion spring 6 rests on the lower surface of the upper clamp 1, and the other end rests on the upper surface of the lower clamp 2. Therefore, the torsion spring 6 provides a restoring force, so that the front ends of the upper and lower clamps tend to fit together, thereby completing the fixation of the electrical components.

[0050] like Figure 3 As shown, a PCB line board is further provided on the upper surface of the upper clip, and the first power connection component and the second power connection component are electrically connected through the PCB line.

[0051] One end of the PCB circuit is connected to the bottom of the first electrical connection protrusion 7, and the other end is connected to the bottom of the second electrical connection protrusion 8. The first electrical connection protrusion 7 and the second electrical connection protrusion 8 are electrically connected through the PCB circuit.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
