Description

Technical Field

[0001] This utility model relates to the technical field of DC power supply plug-in / plug-out testing equipment, specifically a modular plug-in / plug-out mechanism for testing DC power supplies. Background Technology

[0002] A DC power module is a modular electronic device that converts alternating current (AC) or other forms of electrical energy into a stable DC output. It features small size, high efficiency, and adjustable output voltage / current, and is widely used in electronic equipment, communication systems, and industrial control. Different specifications of DC power supplies can be provided to meet various requirements. The insertion / removal test targets the interface between the DC power module and external circuitry. By simulating frequent insertion and removal actions during actual use, it tests the contact reliability, mechanical strength, and electrical performance stability of the interface.

[0003] A search revealed Chinese patent application CN202322830559.4, which discloses a plug-in mechanism for a power supply aging test device. The mechanism includes a main body, a fixing mechanism, and a drying mechanism. The fixing mechanism is located inside the main body, and the drying mechanism is located above it. The main body includes an insulating housing, a load-bearing base, supporting legs, a movable cabinet door, a fixed handle, a controller, and an observation glass. The load-bearing base is fixedly installed at the lower end of the insulating housing, and the supporting legs are fixedly installed at the lower end of the load-bearing base. The movable cabinet door is movably installed at the front end of the insulating housing, and the fixed handle is fixedly installed at the front end of the movable cabinet door. The controller is fixedly installed to the left of the fixed handle.

[0004] The above-mentioned technical solutions and traditional power plug-in / plug-out testing equipment still have shortcomings, such as the lack of modular structure, the plugs used during plug-in / plug-out testing are prone to fatigue damage after long-term use, and it is difficult to replace the plugs, thereby reducing the efficiency of the equipment.

[0005] Therefore, we need to propose a modular plug-in mechanism for a DC power supply used for testing. Utility Model Content

[0006] The purpose of this invention is to provide a modular plug-in / plug-out mechanism for a DC power supply for testing. When the plug suffers fatigue damage after prolonged use, it can be easily and quickly disassembled and replaced, avoiding the hassle of replacing the entire device due to plug damage, reducing equipment maintenance costs, and improving equipment utilization efficiency, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A modular plug-in / plug-out mechanism for a DC power supply for testing, comprising:

[0009] A base, on which a support plate is provided, the support plate being arranged in an inverted L-shape;

[0010] A plug-in / plug-out mechanism is provided on the support plate. The plug-in / plug-out mechanism includes a cylinder and a plug. The cylinder is installed on the top of the support plate. The lower end of the piston rod of the cylinder passes through the support plate and is connected to a lifting plate. A fixing plate is provided on the top of the plug. The fixing plate and the lifting plate are fixed together by screws.

[0011] Preferably, both the lifting plate and the fixing plate are designed in a disc shape, and screw holes for installing screws are correspondingly provided on the lifting plate and the fixing plate.

[0012] Preferably, it also includes a test frame, which is set on the base. During testing, the DC power supply is placed inside the test frame, and the DC power supply socket corresponds to the plug above.

[0013] Preferably, it also includes a positioning mechanism, which is disposed on both sides of the test frame to prevent the power supply support from shifting up and down during insertion and removal.

[0014] Preferably, one end of the threaded rod is provided with a handwheel, and the other end of the threaded rod is provided with a clamping block. The outer wall of the clamping block is bonded with a rubber pad with a diamond-shaped anti-slip texture. When the power module is placed behind the test frame, rotating the handwheel causes the clamping block to clamp and position the power module on both sides.

[0015] Preferably, the plug cavity has multiple sets of pins distributed inside, a rubber plate is slidably disposed inside the plug cavity, and a through hole is opened on the rubber plate for the pins to pass through. The edge of the rubber plate and the plug cavity are fitted with a clearance.

[0017] When inserted, the rubber plate is squeezed and slides upward inside the plug cavity, and the pins are inserted into the slot of the power module through the through hole without obstructing the insertion of the pins;

[0018] When pulled out, the compressed spring causes the rubber plate to return to its lowest position, re-protecting the plug and pins.

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] A modular plug-in / plug-out mechanism for a DC power supply for testing, comprising:

[0031] A base 1, on which a support plate 2 is provided, the support plate 2 being arranged in an inverted L-shape;

[0032] A plug-in / plug-out mechanism is installed on the support plate 2. The mechanism includes a cylinder 3 and a plug 4. The cylinder 3 is mounted on the top of the support plate 2. The lower end of the piston rod of the cylinder 3 passes through the support plate 2 and is connected to a lifting plate 9. A fixing plate 10 is installed on the top of the plug 4. The fixing plate 10 and the lifting plate 9 are fixed together by screws. Both the lifting plate 9 and the fixing plate 10 are disc-shaped, and screw holes for installing screws are correspondingly opened on the lifting plate 9 and the fixing plate 10.

[0033] In use, the power module is placed on the test frame 5 of the base 1. The cylinder 3 serves as the power source, and the piston rod extends and retracts through the intake and exhaust of compressed air. When the piston rod of the cylinder 3 extends downward, it drives the connected lifting plate 9 to move downward. Since the plug 4 is fixed to the lifting plate 9 by the fixing plate 10 and screws, the plug 4 also moves downward, achieving the insertion action. Conversely, when the piston rod retracts upward, the plug 4 moves upward, achieving the extraction action. The disc-shaped design of the lifting plate 9 and the fixing plate 10, along with the corresponding screw holes, facilitates the installation and removal of screws, thereby enabling quick replacement of the plug 4.

[0034] The above technical solution enables automatic insertion and removal of plug 4, improving testing efficiency and reducing manual operation intensity and errors. Simultaneously, the modular installation method of plug 4 facilitates replacement when it suffers fatigue damage, improving equipment utilization efficiency.

[0035] For a preferred implementation, please refer to Figure 1-2 :

[0036] It also includes a test frame 5, which is set on the base 1. During the test, the DC power supply is placed inside the test frame 5, and at this time the DC power supply socket corresponds to the plug 4 above.

[0037] Test frame 5 provides a fixed placement space for the DC power supply. Its position and size are carefully designed so that when the DC power supply is placed in test frame 5, its socket can accurately correspond to the plug 4 above, ensuring smooth plugging and unplugging operations. Standardizing the placement of the DC power supply makes plugging and unplugging operations more accurate and convenient, avoiding difficulties in plugging and unplugging or damage to equipment due to inaccurate power supply placement, and improving the stability and reliability of the test.

[0038] For a preferred implementation, please refer to Figure 1-2 :

[0039] It also includes a positioning mechanism, located on both sides of the test frame 5, to prevent the power supply support from shifting vertically during insertion and removal. The positioning mechanism includes a protrusion 6 and a threaded rod 7. The protrusion 6 is located on the edge of the test frame 5, and the threaded rod 7 is threaded onto the protrusion 6. One end of the threaded rod 7 is equipped with a handwheel, and the other end is equipped with a clamping block 8. The outer wall of the clamping block 8 is bonded with a rubber pad with a diamond-shaped anti-slip texture. When the power module is placed in the test frame 5, rotating the handwheel causes the clamping block 8 to clamp and position the power supply on both sides.

[0040] The protrusion 6 is fixed to the edge of the test frame 5, providing a mounting base for the threaded rod 7. When the handwheel is rotated, the threaded rod 7 rotates within the protrusion 6 and moves axially, thereby causing the clamping block 8 to move towards or away from the power module. After the power module is placed in the test frame 5, rotating the handwheel causes the clamping block 8 to move closer to the power module and clamp its sides. The rubber pad with diamond-shaped anti-slip texture increases the friction between the clamping block 8 and the power module, preventing the power module from shifting vertically during insertion and removal.

[0041] The above technical solution ensures that the position of the power module is fixed during the insertion and removal process, avoiding inaccurate insertion and removal or damage to plug 4 and the socket of the power module due to the movement of the power module, thereby improving the stability and safety of the test.

[0042] The sum of the thicknesses of the protrusions 6 and the clamps 8 is less than the thickness of the frame of the test frame 5, so that the insertion and removal of the power module is not hindered when the protrusions 6 and the clamps 8 are in contact.

[0043] For a preferred implementation, please refer to Figure 3-5 :

[0044] The plug 4 has multiple sets of pins 11 distributed inside its cavity. A rubber plate 12 is slidably disposed inside the plug 4, and the rubber plate 12 has through holes 13 for the pins 11 to pass through. The edge of the rubber plate 12 is fitted with a clearance fit to the inner cavity of the plug 4. A connecting rod 14 is symmetrically disposed on the top of the rubber plate 12. The connecting rod 14 is slidably inserted into the top of the plug 4, and a limit block is provided at the upper end of the connecting rod 14. A compression spring 15 is sleeved on the connecting rod 14 between the rubber plate 12 and the top of the plug 4. Under normal conditions, the rubber plate 12 is located at the lower end of the plug 4, covering the opening of the plug 4 to protect the plug 4 and the pins 11. When inserted, the rubber plate 12 is compressed and slides upward inside the plug 4, and the pins 11 are inserted into the slot of the power module through the through holes 13 without obstructing the insertion of the pins 11. When pulled out, the compression spring 15 causes the rubber plate 12 to return to its lowest position to protect the plug 4 and the pins 11 again.

[0045] Under normal conditions, the compression spring 15 is in its natural state, pressing the rubber plate 12 against the lower end of the plug 4, covering the opening of the plug 4 and protecting the pin 11 from external dust, debris, etc. When the plug 4 is inserted downwards into the slot of the power module, the rubber plate 12 is compressed by the power module, overcoming the elastic force of the compression spring 15, and slides upwards inside the plug 4. The pin 11 then smoothly inserts into the slot of the power module through the through hole 13 on the rubber plate 12. When the plug 4 is pulled out, the compression spring 15 returns to its original state, pushing the rubber plate 12 downwards to cover the opening of the plug 4 again, thus protecting the plug 4 and the pin 11.

[0046] The above technical solution effectively protects plug 4 and pin 11, reduces wear and corrosion of pin 11, extends the service life of plug 4, and lowers equipment maintenance costs. Furthermore, the automatic protection design requires no manual intervention, making operation convenient and quick.

[0047] The power source for cylinder 3 is a compressed air system.

[0048] Composition: Air compressor (discharge volume ≥ 0.3 m³ / min, pressure 0.6-0.8 MPa) + air tank (volume ≥ 60 L) + pneumatic triplet (filter, pressure reducing valve, oil mist lubricator).

[0049] Working principle: The air compressor generates compressed air, which is then pressure-stabilized by the air tank and delivered to the cylinder through the air pipe; the pneumatic triplet filters impurities (filtration accuracy ≤5μm), regulates the air pressure (working pressure 0.4-0.6MPa adjustable) and provides lubrication to ensure smooth cylinder operation.

[0050] Please refer to Figure 1 and 3 Both sides of the lifting plate 9 are equipped with connecting plates, and the ends of the connecting plates are equipped with guide rods. The guide rods are slidably inserted into the support plate to guide the insertion and removal process.

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
