  "abstract": "A connection structure of an inductive element includes a circuit substrate, in inductive element, at least one connection wire, a supporting element, a containing element, a positioning element, a connecting element, and a locking element. The circuit substrate has a through hole. Each connection wire has a first end connected to the inductive element, and a fixed terminal is disposed on a second end of the connection wire. The containing element is formed on the supporting element to provide a containing space. The positioning element is contained in the containing space, and provides a positioning part. The connecting element has a first connecting part and a second connecting part. The first connecting part is connected to the positioning part to clip the fixed terminal. The locking element has a locking part. The locking part is connected to the second connecting part to lock on the circuit substrate.",

  "description_excerpt": "The present disclosure relates to a connection structure, and more particularly to a connection structure of inductive element.\n\nThe statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.\n\nPlease refer to FIG. 1, which shows a circuit block diagram of a grid-connected inverter system of the related art. The grid-connected inverter system is provided to convert a DC power source Vdc generated from renewable energy, such as solar energy, wind energy, or so on into an AC power source Vac to feed into an electrical grid. In the grid-connected inverter system, a front stage DC-to- DC converter 11 A is used to adjust a voltage value of the DC power source Vdc, such as a boost converter for stepping up the DC power source Vdc. A next stage DC-to- AC converter 12 A is used to convert the DC power source Vdc into an AC power source. The filter 13 A is used to filter the AC power source to feed into the electrical grid.\n\nIn the DC-to- DC converter 11 A, a boost inductor is usually used, and in the filter 13 A, a filter inductor is usually used. However, unwanted interference in the system would be generated from the boost inductor and/or the filter inductor.\n\nPlease refer to FIG. 2 A and FIG. 2 B, which show an assembled sectional view and an assembled top view of a first connection manner between an inductor 20 A and a circuit board 10 A of the related art, respectively. A connection manner between an inductor 20 A and a circuit board 10 A is shown in FIG. 2 A and FIG. 2 B.",
