Description

Technical Field

[0001] The utility model relates to the technical field of coupled inductors, and specifically relates to a coupled inductor. Background Technique

[0002] A coupled inductor is an electromagnetic component, usually used in transformers, radio equipment, electronic instruments and other applications that require controlling or transferring electrical energy. It consists of two or more coils wound together. The magnetic field of one coil affects the current and voltage of the other coil. The basic principle of a coupled inductor is Faraday's law of electromagnetic induction, that is, a changing magnetic field will generate an electromotive force (EMF) in the adjacent coil. When an alternating current passes through one of the coils, the magnetic field it generates will change, thereby generating an electromotive force in the other coil. This electromotive force can be used to drive a load or transmit a signal.

[0003] Although the existing coupled inductors are widely used, they still have some deficiencies. For example, there is no protection measure outside the coupled inductor. When transporting the coupled inductor, the externally exposed coils are easily damaged, and its pins are vertically arranged and easily broken. Since the function of the pins is to ensure the stability of the inductor during operation, it is necessary to protect the pins to prevent the pins from being broken by external forces and causing the inductor to operate unstably. Therefore, a coupled inductor is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a coupled inductor 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] A coupled inductor includes an inductor body. A bottom plate is fixedly connected to the bottom end of the inductor body. A fixing frame is arranged outside the bottom plate. Horizontally arranged first through holes that penetrate the fixing frame are symmetrically arranged up and down outside the fixing frame. Horizontally arranged round holes are symmetrically arranged outside the bottom plate. A threaded groove that is symmetrically arranged on the inner side of the bottom plate and communicates with the round hole is arranged on one side of the round hole. A threaded block is spirally connected inside the threaded groove. One side of the threaded block close to the round hole is fixedly connected with a connecting rod located inside the round hole. The end of the connecting rod far from the threaded block is fixedly connected with a nut. A protective cover is arranged above the fixing frame. Rotating shafts that are symmetrically arranged on both sides of the protective cover and are rotationally connected to the protective cover are arranged. A fixing plate is fixedly connected to the outside of the rotating shaft. A first magnet is fixedly connected to the side of the fixing plate close to the fixing frame. A second magnet is magnetically connected to the side of the first magnet far from the fixing plate.

[0007] Preferably, a vertically arranged pin that penetrates the bottom plate is slidably connected to the bottom end of the bottom plate. A chute that penetrates the bottom plate is provided at the top end of the bottom plate. Symmetrically arranged vertically and fixedly connected to the fixed frame are sliders inside the fixed frame. Vertically and symmetrically arranged on the outer side of the pin are second through holes that penetrate the pin.

[0008] Preferably, the number of the pins is multiple, and the pins are evenly distributed at the edge of the bottom end of the bottom plate. The inner diameter of the second through hole is the same as the inner diameter of the first through hole. The connection mode between the chute and the slider is a sliding connection.

[0009] Preferably, the inner side of the fixed frame is closely attached to the outer side of the bottom plate.

Subsequently, the threaded block and the connecting rod are inserted into the inner sides of the first through hole and the round hole located below, and the nut is rotated to make the threaded block and the threaded groove in a spiral connection. Next, the protective cover is placed on the top end of the fixed frame, and the fixed plate on the outer side of the rotating shaft is rotated until the first magnet and the second magnet are magnetically attracted and connected. At this time, the fixed frame is fixedly connected to the outer side of the bottom plate, and the protective cover is fixedly connected to the top end of the fixed frame. The protective cover and the fixed frame cooperate to prevent the coupling inductor from being damaged during transportation;

At this time, both the pins and the fixing frame are located below the bottom plate. After fixing the pins on the circuit board or the machine, the fixing frame can protect the pins from being broken by external force. Description of the Drawings
