Description

Technical Field

[0001] The utility model belongs to the technical field of adjustable coil inductance, and particularly relates to an adjustable coil inductance device. Background Technique

[0002] An inductor, also known as a choke, a reactor, or a dynamic reactor, is a component that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding. It is generally composed of a skeleton, a winding, a shielding cover, a packaging material, a magnetic core or an iron core, etc. The characteristics of an inductor are exactly opposite to those of a capacitor. It has the characteristic of blocking alternating current and allowing direct current to pass through smoothly. For traditional inductors that adjust the coil length, when people use inductors, they often need to wind the coil, and the coil often winds messily during manual winding. If not solved in time, it will affect the normal operation of the equipment, resulting in the inductor being unable to work properly, with low economic benefits and poor practicability.

[0003] Currently, the existing adjustable coil inductance devices do not have the function of adjusting the position of the contact. Since the inductance value cannot be adjusted by changing the effective number of turns of the coil, users may need to replace different coils when facing different circuit requirements, which limits the flexibility and adaptability of the device. Users may need to manually replace the coil or perform other complex operations to adjust the inductance value, which increases the complexity and inconvenience of the operation. To meet different inductance requirements, users may need to purchase and maintain multiple coils of different specifications, which will increase additional costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable coil inductance device, aiming to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An adjustable coil inductance device includes a device body, and also includes: a contact:

[0007] An adjusting mechanism is arranged on the surfaces of the left and right sides of the device body and is used to adjust the position of the contact;

[0008] A tensioning mechanism is arranged on the surface of the adjusting mechanism;

[0009] A fixing mechanism is arranged at the bottom of the device body and is used to fix the stability of the whole device.

[0010] As a preferred scheme of the utility model, a fixing ring is fixedly installed on the top of the device body, and a hexagon bolt is threadedly connected to the surface of the fixing ring.

[0011] As a preferred solution of the utility model, a threaded rod is movably connected inside the device body, a slider is movably connected to the surface of the threaded rod, an adjustment knob is fixedly installed at the top of the threaded rod, and the threaded rod is movably connected to the fixed ring.

[0012] As a preferred solution of the utility model, a chute is provided on the surface of the device body, and a pulley is movably connected to the surface of the chute.

[0013] As a preferred solution of the utility model, a rubber rod is fixedly installed on the surface of the slider, a spring is fixedly installed inside the rubber rod, a movable rod is fixedly installed at the top of the spring, the movable rod is movably connected to the rubber rod, and a contact head is fixedly installed at the top of the movable rod.

[0014] As a preferred solution of the utility model, a support leg is fixedly installed at the bottom of the device body, and a base is fixedly installed at the bottom of the support leg.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] For this adjustable coil inductance device, by setting an adjustment mechanism, it can effectively realize the function of sliding a contact head on the coil to change the effective number of turns of the coil during the use of the device, thereby adjusting the inductance value. Through the adjustment mechanism, users can adjust the inductance value in real time without replacing the coil. This flexibility enables the device to adapt to various circuit designs and experimental requirements. The device allows users to finely adjust the effective number of turns of the coil by sliding the contact head, thereby achieving precise control of the inductance value, which is particularly important for experiments and applications that require fine adjustment. Users do not need to disassemble or rewind the coil, and only need to operate through the adjustment mechanism to change the inductance value, which greatly simplifies the operation process and improves work efficiency.

[0018] For this adjustable coil inductance device, by setting a tensioning mechanism, it can effectively realize the function of keeping the contact head always in contact with the copper coil with the same pressure during the use of the device. The tensioning mechanism ensures that the contact pressure between the contact head and the copper coil always remains consistent, which helps to maintain a stable inductance value and reduce performance fluctuations caused by poor contact. Consistent contact pressure can prevent electrical failures caused by loose or poor contact of the contact head, improve the reliability and service life of the device, and stable contact pressure helps to accurately measure and control the inductance value, which is particularly important for applications that require high-precision inductance adjustment.
