Description

Technical Field

[0001] The invention relates to the technical field of voltage detection devices, in particular to a voltage detection device for a computer power supply. Background Art

[0002] The power supply is an important part of the computer, providing a stable power supply for the computer to ensure the normal operation of the computer. However, in the actual use of the computer, there will always be various problems and faults, such as failure to boot up, so the computer power supply detection is a very important test content. Common detection methods include: multimeter detection, adjust the multimeter to the DC voltage measurement position, insert the red measurement lead into the "VΩmA" jack of the multimeter, insert the black measurement lead into the "COM" jack, clip the red measurement lead to the green wire of the 24-pin power socket of the power motherboard, and clip the black measurement lead to the black wire of the socket. Turn on the power and read the voltage value on the multimeter. Generally, the +12V voltage and +5V voltage output by the power supply should be close to the rated value, otherwise there may be a problem with the power supply; or use a power supply tester to test: the power supply tester is used to test the output voltage, current, power and other parameters of the power supply. First, plug the power supply tester into the power socket, and then plug the computer power supply plug into the output interface of the tester. By observing the display screen on the tester, you can know the output of the power supply. Compare and analyze the measured data with the set threshold to determine whether the computer power supply is normal.

[0003] The power supply for a computer usually has multiple branch sockets, which can be connected to hardware such as the motherboard, CPU and graphics card for power supply. When performing voltage detection, because there are many power supply cables and sockets, although some cables have been bundled, there are still many branch cables near the sockets, resulting in confusion and difficulty in distinguishing the connections between the sockets and cables. It is necessary to manually separate the connections between the sockets and cables before performing voltage detection. This method has low detection efficiency, and the detection end needs to be inserted into the socket during the detection process. The existing technology lacks a limiting effect on the power socket, which easily causes the socket and the detection end to separate during the detection process, affecting the accuracy of voltage detection. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a computer power supply voltage detection device to solve the problems raised in the above-mentioned background technology.

The limiting frames are connected to different branches, and all the socket strips are unfolded along the upper long board and the lower long board to facilitate the detection of voltage values ​​in different socket strips. There is a distance between them, so the problem of cable crossing and confusion will not occur, thereby improving the detection efficiency.

The cable 51 and one end of the socket 52 of the power supply body 5 can pass through the threading port 66 and overlap on the top of the lower long plate 44.

[0031] In this embodiment, the moving assembly 3 also includes a screw, one end of the moving plate 33 is threadedly inserted with a first screw 31, and both ends of the first screw 31 are rotatably mounted on the detection platform 1 through a mounting frame, the other end of the moving plate 33 is slidably inserted with a slide bar 32, and both ends of the slide bar 32 are fixedly mounted on the detection platform 1 through a mounting frame, a moving frame 34 is fixed at the bottom of the moving plate 33, and a second screw 35 is rotatably mounted inside the moving frame 34 through a bearing, the second screw 35 is a bidirectional screw, and both ends of the second screw 35 are threadedly sleeved with a moving block 36, and the top of the moving block 36 is fixed There is an electric push rod 37, a plug plate 47 is fixed at the bottom of the electric push rod 37, the plug plate 47 is slidably buckled on the top surface of the upper long plate 45, and a plug frame 43 is slidably installed on the surface of the lower long plate 44 at a position corresponding to the plug plate 47, and the plug plate 47 can be slidably inserted into the plug frame 43. The limiting component 4 also includes a first slide groove 41, and the detection table 1 is provided with a first slide groove 41 at a position corresponding to the bottom of the plug frame 43. A first slider 413 is slidably connected inside the first slide groove 41, and a first spring 42 is fixed between the first slider 413 and the first slide groove 41. When the power supply body 5 is placed in the placement group After the cable 51 and the plug strip 52 are located at the top of the lower long plate 44 inside the component 6, the movable plate 33 moves the upper long plate 45 to the top of the lower long plate 44 through the rotation of the first screw 31, and then the electric push rod 37 drives the plug plate 47 and the upper long plate 45 to descend, and the plug plate 47 is inserted into the insertion frame 43. The upper long plate 45 cooperates with the lower long plate 44 to limit the cable 51, and then the first screw 31 drives the movable plate 33 to move toward one end of the voltage tester 2, and through the limitation of the upper long plate 45 and the lower long plate 44, the plug strip 52 is pushed to move, and the first slider 413 at the bottom of the insertion frame 43 slides along the first slide groove 41, stretching the first spring 4 2, until the cable 51 is flattened, then the second screw 35 in the moving frame 34 rotates, the two moving blocks 36 move in the opposite direction, and the electric push rod 37 drives the plug board 47 and the plug frame 43 to move to both sides. Because the plug frame 43 and the second slider 62 are connected by the protrusion 414 and the card slot 412, they can be separated during horizontal movement, and the ends of the plug strip 52 are separated to avoid overlapping and affecting the detection. In the process of horizontal expansion of the plug strip 52, the branch cables 51 will also move with it, expanding the distance between the branches, so as to facilitate the distinction between cables 51 of different colors. The first screw 31 and the second screw 35 are both controlled by the motor.

[0032] In this embodiment, a protrusion 414 is fixed on the top of the first sliding block 413, a slot 412 is provided at the bottom of the inserting frame 43, and the protrusion 414 can be slidably engaged in the slot 412, a vertical slide rail 410 is slidably engaged on the back of the limit frame 48, and a second spring 411 is fixed between the two sides of the vertical slide rail 410 and the limit frame 48, a connecting rope 49 is fixed on the top of the adjacent vertical slide rail 410, the two outermost connecting ropes 49 on the cable 51 are fixedly connected to the inserting plate 47, a transverse slide rail 46 is fixed on the back of the upper long board 45, and The vertical slide rail 410 is slidably sleeved on the surface of the horizontal slide rail 46. The number of limit frames 48 can be determined according to the number of socket strips 52 provided with different models of power supplies, and the size of the bottom opening of the limit frame 48 is also adapted to the size of the socket strips 52. In short, the smaller the socket strips 52 are, the fewer cables 51 are connected to the back, and the smaller the opening of the limit frame 48 is required, and vice versa. The position of the limit frames 48 can be fine-tuned on the horizontal slide rail 46 in advance so that they are located at the top of each socket strip 52 branch cable 51 and connected by pull ropes between them, such as Figure 4 As shown, the branch cable 51 behind the socket strip 52 with more slots is also wider, so the available length of the pull rope between the two adjacent limit frames 48 at this position is shorter. When the cable 51 is flattened as the socket strip 52 moves, the branch of each socket strip 52 will leak out, and there will be gaps between the branches. At this time, through the elastic force of the second spring 411, the limit frame 48 slides along the vertical slide rail 410 and is connected to the branch surface. Subsequently, when the plug plate 47 moves to both sides, it can drive the limit frame 48 and the vertical slide rail 410 to slide along the horizontal slide rail 46, thereby separating the four groups of socket strips 52 horizontally, making it convenient to perform voltage testing on different models one by one.

[0033] When the device is in use, the limiting plate 64 slides along the second slide groove 61 through the guidance of the four inclined plates 65, and the four sides of the power supply body 5 are squeezed and wrapped by the elastic force of the third spring 63, and the cable 51 of the power supply body 5 and one end of the plug strip 52 can pass through the threading hole 66 and overlap on the top of the lower long plate 44, and the movable plate 33 moves the upper long plate 45 to the top of the lower long plate 44 through the rotation of the first screw rod 31, and then the electric push rod 37 drives the plug plate 47 and the upper long plate 45 to descend, and the plug plate 47 is inserted into the insertion frame 43, and the upper long plate 45 cooperates with the lower long plate 44 to limit the cable 51, and then the first screw 31 drives the movable plate 33 to move toward one end of the voltage tester 2, and through the limitation of the upper long plate 45 and the lower long plate 44, the plug strip 52 is pushed to move, and the first slider 413 at the bottom of the insertion frame 43 slides along the first slide groove 41, stretching the first spring 42 until the cable 51 is flattened, and then the movable frame 34 is moved. The second screw 35 rotates, the two moving blocks 36 move in the opposite direction, and the electric push rod 37 drives the plug board 47 and the plug frame 43 to move to both sides. Because the plug frame 43 and the second slider 62 are connected by the protrusion 414 and the card slot 412, they can be separated during horizontal movement, and the ends of the plug strip 52 are separated to avoid overlapping and affecting the detection. In the process of horizontal expansion of the plug strip 52, the branch cable 51 will also move with it to expand the spacing between the branches. When the cable 51 is flattened with the movement of the plug strip 52, the branch of each plug strip 52 will leak out, and there will be gaps between the branches. At this time, through the elastic force of the second spring 411, the limit frame 48 slides along the vertical slide rail 410 and is connected to the branch surface. Subsequently, when the plug board 47 moves to both sides, it can drive the limit frame 48 and the vertical slide rail 410 to slide along the horizontal slide rail 46, and the four groups of plug strips 52 are separated horizontally, which is convenient for one-to-one voltage testing of different models.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
