Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an improved inductor device. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is turned on, it will try to impede the current from flowing through it. If the inductor is in a state with current passing through, when the circuit is turned off, it will try to maintain the current unchanged. Since electronic products contain many electronic components, and each electronic component will generate a large amount of electromagnetic wave interference, especially at the power supply end of electronic products. A large amount of electromagnetic waves seriously interfere with the operation of each electronic component itself, and even more seriously, it may cause damage or failure of electronic products. The existing anti-interference protection shell has a complex structure, and it is not convenient to disassemble and repair the shell when the components inside the shell are damaged, which reduces the repair rate. In addition, in the installation of the existing inductor, for the installation of the inductor, only the welding method is used to connect it to the circuit. If the inductor coil is not fixed, it is easy to shake during use, resulting in the problem of solder joint detachment. Content of the Utility Model

[0003] The purpose of the utility model is to provide an improved inductor device to overcome the above-mentioned defects in the prior art.

[0004] According to an improved inductor device of the utility model, it includes a protection shell, an inductor coil body and a circuit board for being installed in the protection shell. A receiving cavity is provided in the protection shell. Symmetric telescopic grooves are provided in the left and right side walls of the receiving cavity. In the receiving cavity, movable plates are arranged symmetrically left and right. Clamping plates are fixedly arranged on the opposite sides of the movable plates on the left and right sides. A top pressure spring is connected in a top pressure fit on the side of the movable plate away from the clamping plate. A linkage slider is slidably connected in the telescopic groove. One end of the linkage slider is fixedly connected to the movable plate. A through groove is provided in the linkage slider and runs through up and down. A guide sliding groove is provided in the top wall of the telescopic groove. A movable block is slidably connected in the guide sliding groove. A tension spring is provided at the top of the movable block. A toothed block is fixedly arranged at the bottom of the movable block. A movable rod extending up and down is slidably connected in the bottom wall of the telescopic groove. The top end of the movable rod passes through the through groove and is fixedly connected to the bottom of the toothed block. The extended section at the bottom of the movable rod extends out of the bottom end face of the protection shell, and a thread is provided on the extended section at the bottom of the movable rod.

[0022] When the utility model is in use: First, the inductance coil body 5 is installed in the accommodation cavity 3, so that the inductance coil body 5 is kept between the clamping plates 8 on the left and right sides. Through the elastic force of the pressing spring 7, the clamping plates 8 are tightly clamped with the inductance coil body 5 in a matching manner, and the pins on the inductance coil body 5 are installed in the opening grooves 16. At this time, the protective cover 19 is tightly installed with the protection housing 1 through the bolt 20. Then, the protection housing 1 is moved to the installation position of the circuit board 2, so that the bottom section of the movable rod 17 passes through the installation hole on the circuit board 2. Then, the nut 18 is threadedly engaged with the bottom end of the movable rod 17, so that the movable rod 17 drives the tooth block 14 to move downward, so that the bottom end face of the tooth block 14 is tightly connected with the anti-slip sheet 11 on the linkage slider 9, thereby realizing the locking of the clamping plate 8, and further realizing the fixation of the inductance coil body 5; When it needs to be disassembled, by unscrewing the nut 18, the movable block 13 and the tooth block 14 at the bottom of the movable block 13, due to the tensile force of the tension spring 15, the tooth block 14 is far away from the anti-slip sheet 11.
