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.

First claim

What is claimed is:

1. A connection structure of an inductive element, comprising:
a circuit substrate having a through hole;
an inductive element and at least one connection wire, and each connection wire having a first end connected to the inductive element and a second end being opposite to the first end and having a fixed terminal disposed on the second end;
a supporting element disposed on a base body, arranged in a contact manner with and inside the inductive element, and configured to support the connection wire;
a containing element formed on the supporting element and configured to provide a containing space;
a positioning element contained in the containing space, and the positioning element having a positioning part;
a connecting element having a first connecting part and a second connecting part, and the first connecting part connected to the positioning part to clip the fixed terminal; and
a locking element having a locking part, and the locking part configured to connect to the second connecting part to lock the locking element and the connecting element on the circuit substrate.

2. The connection structure of the inductive element in claim 1 , wherein the positioning part is a concave structure, the first connecting part is a convex structure, the second connecting part is a concave structure, and the locking part is a convex structure.

3. The connection structure of the inductive element in claim 1 , wherein the positioning part is a concave structure, the first connecting part is a convex structure, the second connecting part is a convex structure, and the locking part is a concave structure.

4. The connection structure of the inductive element in claim 1 , wherein the positioning part is a convex structure, the first connecting part is a concave structure, the second connecting part is a concave structure, and the locking part is a convex structure.

5. The connection structure of the inductive element in claim 1 , wherein the positioning part is a convex structure, the first connecting part is a concave structure, the second connecting part is a convex structure, and the locking part is a concave structure.

6. The connection structure of the inductive element in claim 1 , wherein the connection wire is connected to one side, which is away from the positioning element, the connecting element, or the locking element, of the inductive element.

7. The connection structure of the inductive element in claim 1 , wherein the connection wire is connected to one side, which is near the positioning element, the connecting element, or the locking element, of the inductive element.

8. The connection structure of the inductive element in claim 1 , further comprising:
a metal plate disposed between the circuit substrate and the connection wire.

9. The connection structure of the inductive element in claim 1 , wherein the fixed terminal is a ring-shaped terminal, a C-shaped terminal, a U-shaped terminal, or a V-shaped terminal.

10. The connection structure of the inductive element in claim 1 , wherein the supporting element is integrally or detachably formed with the containing element.

11. The connection structure of the inductive element in claim 1 , wherein the base body is an inner base of a case, and a glue is injected into an inner space of the case to fix the inductive element.

12. The connection structure of the inductive element in claim 2 , wherein the positioning element is a nut.

13. The connection structure of the inductive element in claim 2 , wherein the locking element is a screw.
