Description

Technical Field

[0001] This utility model relates to the technical field of voltage regulation devices, specifically a voltage regulation device for current detection. Background Technology

[0002] A voltage regulator is an electronic or electrical device used to maintain or control the voltage of a circuit or system at a constant level, or to adjust the voltage as needed.

[0003] During circuit testing, the voltage is often constant. To adjust the voltage of the circuit under test, it is often necessary to use a resistor divider. In a series circuit, installing a resistor will cause the voltage in the subsequent testing circuit to drop, and the drop value is related to the resistance value of the added resistor. Therefore, when testing, only the rated resistor is added. If testing is required under different voltage conditions, it is necessary to replace it with a resistor with a different resistance value, which is relatively troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a voltage regulation device for current detection to solve the problems mentioned in the background art.

A terminal block is fixed on the outer side of the support plates. An input contact is installed on the inner side of the support plates at a position corresponding to the terminal block. The rotating column is rotatably connected between the support plates. Four front-end contacts and four end contacts are respectively installed on both sides of the rotating column in a circumferential array. The uppermost front-end and end contacts abut against the corresponding input contacts. An adjustment cavity is formed inside the rotating column at a position corresponding to the front-end contacts. An insulating column is fixed inside each adjustment cavity. A resistance coil is wound around the insulating column. An adjustment slider is slidably connected to the outer wall of the adjustment cavity. A fixing assembly is provided between the rotating column and the support plates. The outer side of the adjustment slider is connected to the end contacts via a movable copper strip and a fixed copper strip. The inner side of the adjustment slider abuts against the outer side of the resistance coil. The resistance coil is connected to the front-end contacts via a current-carrying wire. The input contacts are connected to the terminal block via a conductor.

[0006] Preferably, an annular plate is slidably connected to the outer side of the rotating column, and an insulating block is fixed between the inner side of the annular plate and the adjusting slider.

[0016] 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.

[0017] Please see Figure 1 This utility model provides a technical solution: including a base 1 and a rotating column 2. Support plates 11 are fixed on both sides of the base 1. A terminal block 12 is fixed on the outer side of the support plate 11. An inlet contact 13 is installed on the inner side of the support plate 11 at a position corresponding to the terminal block 12. The rotating column 2 is rotatably connected between the support plates 11. Four front contacts 33 and four end contacts 64 are respectively installed on both sides of the rotating column 2 in a circumferential array. The uppermost front contacts 33 and end contacts 64 abut against the corresponding inlet contacts 13. An adjustment cavity 3 is opened in the rotating column 2 at a position corresponding to the front contacts 33. An insulating column 31 is fixed in each adjustment cavity 3. A resistance coil 32 is wound on the insulating column 31. The internal resistance of the resistance coils 32 in the four adjustment cavities 3 increases sequentially. An adjustment slider 6 is slidably connected to the outer wall of the adjustment cavity 3. A fixing component 5 is provided between the rotating column 2 and the support plate 11. An annular plate 4 is slidably connected to the outer side of the rotating column 2. An insulating block 43 is fixed between the inner side of the annular plate 4 and the adjustment slider 6.

[0018] This invention utilizes the rotation of the rotating column 2 to rotate the designated adjustment cavity 3 to its highest position. Then, by pulling the annular plate 4, the adjustment slider 6 can be moved to change the number of turns of the resistance coil 32 through which the current passes. The more turns, the greater the overall resistance. Resistor coils 32 with relatively higher internal resistance will also have a larger overall resistance even if they have the same number of turns. Therefore, the circuit resistance can be adjusted quickly. The greater the resistance, the greater the voltage it bears in the entire circuit. When current is detected in a series circuit, the voltage at the detection position will be relatively lower, thus achieving the purpose of voltage regulation. The operation is simple and convenient, and the four internally increasing resistance coils 32 can improve the adjustment range.

[0019] The outer side of the adjusting slider 6 is connected to the end contact 64 by a movable copper strip 61 and a fixed copper strip 63. The inner side of the adjusting slider 6 is fixed and abuts against the outer side of the resistance coil 32. The resistance coil 32 is connected to the front contact 33 by a current-carrying wire 34. The inlet contact 13 is connected to the terminal 12 by a conductor. A movable groove 62 is provided in the rotating column 2 and aligned with the adjusting cavity 3. The fixed copper strip 63 is fixed in the movable groove 62 and the end contact 64 is fixedly connected. The movable copper strip 61 is slidably connected in the movable groove 62 at the end away from the adjusting slider 6 and is in contact with the surface of the fixed copper strip 63.

[0020] The entire device is connected to a series circuit via connector 12. The current flows sequentially through the front inlet contact 13, front contact 33, conductor, resistance coil 32, adjusting slider 6, movable copper strip 61, fixed copper strip 63, end contact 64, and end inlet contact 13, forming an uninterrupted circuit.

[0021] The outer side of the rotating column 2 is provided with anti-slip texture 42, and the inner side of the annular plate 4 is fixed with an anti-slip inner ring 41.

[0022] After the ring plate 4 is pulled, the anti-slip texture 42 and the anti-slip inner ring 41 cooperate to increase the friction on the inner side of the ring plate 4, ensuring that it can stay stably after sliding to the designated position.

[0023] The fixing component 5 includes a slot 51 and a telescopic block 52. The slot 51 is opened at the outer end of the rotating column 2 and its position corresponds one-to-one with the adjustment cavity 3. The telescopic block 52 is installed on the inner side of the support plate 11 and is aligned with the slot 51 below. The end of the telescopic block 52 is inserted into the slot 51. A telescopic groove 53 is opened in the support plate 11 at the position aligned with the telescopic block 52. One outer end of the telescopic block 52 is slidably connected in the telescopic groove 53 and a telescopic spring 54 is fixed between it and the inner side wall of the telescopic groove 53. A pull rod 55 is specified at one end of the telescopic block 52 located in the telescopic groove 53. The end of the pull rod 55 extends out of the support plate 11.

[0024] Pulling the lever 55 allows the telescopic block 52 to slide into the telescopic groove 53 while compressing the telescopic spring 54. At this time, the fixing of the rotating column 2 is released. Conversely, by pushing the telescopic spring 54, the telescopic block 52 can be pushed out and inserted into the designated slot 51, which can prevent the rotation of the rotating column 2 and fix the position of the rotating column 2, thereby achieving stable connection between the inlet contact 13 and the front contact 33 and the end contact 64.
