Description

Technical Field

[0001] This utility model belongs to the field of voltage stability testing technology, specifically a power module output voltage stability testing fixture. Background Technology

[0002] In the research, development, production and maintenance of electronic equipment, the power module is the core component for energy supply. Its output voltage stability is directly related to the operational reliability of downstream circuits or equipment. Therefore, conducting output voltage stability testing on the power module is an important step in ensuring the performance of electronic systems.

[0003] During this testing process, it is essential to ensure that the power module maintains a relatively fixed installation posture and position throughout the testing cycle. This is crucial to guarantee the continuity and reliability of the electrical connection between the power module and the testing equipment, and to prevent signal interruption or distortion due to loose connections.

[0004] However, the following problems were found in the implementation of the relevant technologies: One of the current fixing methods for power module testing in the industry is to use a simple mechanical clamp with strong universality to generate horizontal clamping force on the front and rear sides of the power module. However, it only clamps and fixes power modules of some specifications through the front and rear sides and lacks vertical clamping force on the power module. The power module is prone to shaking, which affects the stability of the fixation. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a power module output voltage stability testing fixture, which has the advantage of stably clamping the power module.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power module output voltage stability detection fixing frame, including a workbench, a support frame connected to the top of the workbench, a drive source connected to the inner side of the workbench, a fixing frame body connected to the top of the workbench, a clamping component provided on the support frame, and a fixing component provided on the fixing frame body;

[0007] The surface of the clamping assembly is poweredly connected to the power output end of the drive source to drive the clamping assembly to rotate in opposite directions to adjust the power module to be clamped and fixed on the left and right sides.

[0008] The surface of the fixing component is connected to the surface of the fixing frame to clamp and fix the power module via the upper and lower sides.

[0009] Preferably, the clamping assembly includes a first gear, a second gear, and two sponge rods. The first gear is disposed on the power output end of the drive source, the bottom end of the second gear is rotatably connected to the top end of the support frame, adapter rods are connected to the surfaces of the first gear and the second gear, clamping rods are connected to the surfaces of the two adapter rods, a first high-elasticity silicone pad is connected to the surfaces of the two clamping rods, and the two sponge rods are rotatably disposed at the top end of the support frame.

[0010] Preferably, the first gear meshes with the second gear.

[0011] Preferably, the two clamping rods are symmetrically arranged on the front and rear sides of the vertical center line of the worktable.

[0012] Preferably, the two sponge rods are rotatably connected to the two clamping rods respectively.

[0013] Preferably, the fixing assembly includes two fixing sleeves and two high-elasticity outward expansion springs. One of the fixing sleeves is disposed on the inner side of the top of the fixing frame, and the other fixing sleeve is disposed on the top of the workbench. Limiting slide rods are slidably connected to the inner sides of both fixing sleeves. One end of each of the two limiting slide rods is connected to a limiting plate. A second high-elasticity silicone pad is connected to the surface of each of the two limiting plates. The two high-elasticity outward expansion springs are respectively sleeved on the outer sides of the two fixing sleeves.

[0014] Preferably, the two ends of one of the high-elasticity outward-expanding springs are respectively connected to the inner side of the top of the fixed frame and the surface of one of the limiting plates, and the two ends of the other high-elasticity outward-expanding spring are respectively connected to the top of the workbench and the surface of the other limiting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention facilitates the rotation of the meshing first and second gears via a drive source, which in turn drives the two adapter rods and clamping rods to move in opposite directions. This allows for adjustment of the distance between the two clamping rods according to the size of the power module, enabling the clamping and fixing of power modules of different sizes from the front and rear. Furthermore, the sliding action of the limiting slide rod, combined with the pushing action of the high-elasticity outward-expanding spring, facilitates the upper and lower clamping force of the limiting plate on the power module. Compared to simply clamping the power module from the front and rear, the combined upper and lower clamping force further enhances the stability of the power module's fixation. Additionally, the soft contact force and friction of the first and second high-elasticity silicone pads help protect the power module and improve the stability of contact with it.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a power module output voltage stability testing fixture, including a workbench 1, a support frame 4 connected to the top of the workbench 1, a drive source 5 connected to the inner side of the workbench 1 to facilitate providing driving force for clamping and fixing, a fixing frame 6 connected to the top of the workbench 1, a clamping component 2 provided on the support frame 4, and a fixing component 3 provided on the fixing frame 6.

[0028] The surface of the clamping component 2 is poweredly connected to the power output end of the drive source 5 to drive the clamping component 2 to rotate in opposite directions to adjust the power module to be clamped and fixed on the left and right sides.

[0029] The surface of the fixing component 3 is connected to the surface of the fixing frame 6 for clamping and fixing the power module via the upper and lower sides.

[0030] Specifically, the clamping assembly 2 includes a first gear 21, a second gear 22, and two sponge rods 26. The first gear 21 is mounted on the power output end of the drive source 5. The bottom end of the second gear 22 is rotatably connected to the top end of the support frame 4. Both the surface of the first gear 21 and the surface of the second gear 22 are connected to adapter rods 23. Both adapter rods 23 are connected to clamping rods 24, which facilitates the generation of clamping force on the power module. Both clamping rods 24 are connected to a first high-elasticity silicone pad 25, which facilitates the increase of friction with the power module and the soft texture helps to reduce damage to the power module caused by clamping. Both sponge rods 26 are rotatably mounted on the top end of the support frame 4, which facilitates the provision of support force to the clamping rods 24.

[0031] Furthermore, the first gear 21 is meshed with the second gear 22, which facilitates the rotation of the second gear 22 by the first gear 21.

[0032] Furthermore, the two clamping rods 24 are symmetrically arranged on the front and rear sides of the vertical center line of the workbench 1, which facilitates the generation of clamping force on the power module.

[0033] It is worth noting that the two sponge rods 26 are rotatably connected to the two clamping rods 24 respectively. The soft material of the sponge rods 26 provides support for the clamping rods 24 without affecting the rotation adjustment of the clamping rods 24.

[0034] It is worth noting that the fixing component 3 includes two fixing sleeves 31 and two high-elasticity outward expansion springs 35. One fixing sleeve 31 is located on the inner side of the top of the fixing frame 6, and the other fixing sleeve 31 is located on the top of the workbench 1. The inner sides of both fixing sleeves 31 are slidably connected to limit slide rods 32. One end of each of the two limit slide rods 32 is connected to a limit plate 33, which facilitates the clamping and fixing of the power module from the upper and lower sides. The surfaces of the two limit plates 33 are connected to a second high-elasticity silicone pad 34, which further protects the power module. The two high-elasticity outward expansion springs 35 are respectively sleeved on the outer side of the two fixing sleeves 31.

[0035] It is worth mentioning that the two ends of one of the high-elasticity outward expansion springs 35 are respectively connected to the inner side of the top of the fixed frame 6 and the surface of one of the limiting plates 33, and the two ends of the other high-elasticity outward expansion spring 35 are respectively connected to the top of the worktable 1 and the surface of the other limiting plate 33, so that the two limiting plates 33 have a force of approaching each other, thereby generating a clamping force on the power module.

[0036] The first high-elastic silicone pad 25, the sponge rod 26, and the second high-elastic silicone pad 34 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0037] Working principle: First, when adjusting the distance between the two clamping rods 24 according to the size of the power module, the drive source 5 drives the first gear 21 to rotate. The first gear 21 drives the second gear 22, which meshes with it, to rotate. Thus, the first gear 21 and the second gear 22 synchronously drive the two adapter rods 23 to move in opposite directions relative to the clamping rods 24. Assuming the power module is large, the drive of the first gear 21 will be adjusted to accommodate the... Figure 2 The direction is corresponding to a counterclockwise rotation, which causes the two clamping rods 24 to separate, thereby increasing the distance between the two clamping rods 24 to accommodate a larger power module. At this time, the power module is located between the two limiting plates 33, and the two limiting slide rods 32 will retract into the two fixing sleeves 31 respectively. Under the expansion action of the two high-elasticity outward expansion springs 35, the two limiting plates 33 will drive the power module to generate an up-and-down clamping and positioning force, which, together with the clamping rods 24, enhances the fixing effect on the power module. Similarly, if the power module is smaller, the first gear 21 is driven by the drive source 5 to attach... Figure 2 The direction is to rotate clockwise, thereby bringing the two clamping rods 24 closer together, and then clamping and fixing the smaller power module. The operation is simple and the stability of the power module is improved. Compared with just clamping the power module from the front and back, the combined upper and lower clamping force further improves the stability of the power module, so as to facilitate the subsequent testing of the stability of the power module output voltage.
