[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. The inductor has a certain inductance, and it only hinders the change of current. If there is no current flowing through the inductor, it will try to hinder the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current unchanged when the circuit is disconnected. The inductor is also called a choke, a reactor, or a dynamic reactor. However, when the inductor is connected to the wire, it usually needs to be connected to the connecting metal strip by welding or manual winding. These connection methods are inconvenient to operate and the copper wire can easily cause damage to the user's hands. After improvement, the utility model is provided with a connecting metal strip near the middle position of the rear end. A plug-in slot is provided, a central card piece is provided at the inner position of the connecting metal strip near the end, an arc structure is provided at the rear position of the central card piece, and a built-in extrusion connection spring is connected to the end position of the central card piece, and side toggle blocks are provided on both sides of the central card piece connecting the metal strip. The arc structure position of the central card piece can be adjusted by toggling the side toggle blocks, and the built-in extrusion connection spring can squeeze the central card piece. When the wire needs to be connected, the side toggle blocks are toggled, and then the metal wire part is plugged into the plug-in slot, and the hand is released. The elastic force of the built-in extrusion connection spring can squeeze the metal wire firmly to the edge of the plug-in slot through the central card piece. The installation is simple and convenient, and the replacement is convenient, which can effectively improve the installation efficiency. Utility Model Content
