Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component technology, specifically an inductor pin welding structure. Background Technology
[0002] The conventional design involves direct intermediate frequency spot welding between the inductor pins and the insert. If the tin plating on the inductor pins oxidizes, or the insert surface oxidizes, or the soldering head is severely worn, poor soldering is likely to occur, which can lead to the inductor pins falling off and the circuit becoming open. The soldering reliability is poor. Utility Model Content
[0003] The purpose of this invention is to provide an inductor pin welding structure, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: the inductor pin welding structure includes a socket and two sets of inserts disposed on the socket. At least one connecting part is provided on the section of the inserts away from the socket. The connecting part is integrally formed with the inserts. The connecting part is flexible, and an assembly cavity is formed between the bent connecting part and the inserts.
[0005] Preferably, there are two connecting portions, and there is a gap between the two connecting portions.
[0006] Preferably, the distance between the two connecting parts is 1 mm.
[0007] Preferably, the sum of the widths of all the connecting parts on a single insert is less than the width of the insert.
[0008] Preferably, the assembly cavity formed between the connecting part and the insert is located on the upper surface of the insert.
[0009] Preferably, the insert has a through hole.
[0010] The beneficial effects of this utility model are:
[0011] This welding structure, through bending and squeezing of the connection part, makes the contact between the connection part, capacitor pin, and inductor pin more compact, which can effectively improve the stability of the connection part, capacitor pin, and inductor pin after welding on the plug-in, thereby reducing the possibility of circuit breakage.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0017] like Figure 1-3 As shown, an inductor pin welding structure includes a socket 5 and two sets of inserts 6 disposed on the socket 5. At least one connecting part 7 is provided on a section of the insert 6 away from the socket 5. The connecting part 7 is integrally formed with the insert 6. The connecting part 7 is flexible, and an assembly cavity is formed between the bent connecting part 7 and the insert 6.
[0018] Both insert 6 and connecting part 7 are made of metal, and insert 6 and connecting part 7 are made of the same material. Insert 6 and connecting part 7 can be made of copper.
[0019] The socket 5 also includes a capacitor 3 and two inductors 1. The capacitor 3 has two capacitor leads 4, and each of the two inductors 1 has an inductor lead 2 that connects to the insert 6. When soldering the capacitor leads 4 and inductor leads 2 onto the insert 6, the connecting part 7 is first bent. The bent connecting part 7 forms an assembly cavity with the insert 6. The assembly cavity is not fully enclosed; it is U-shaped. When placing the capacitor leads 4 and inductor leads 2, the movable end of the capacitor lead 4 can be bent to 90° first. Figure 3 As shown, the movable end of the capacitor pin 4 is placed in the assembly cavity, and then the movable end of the inductor pin 2 is passed through the assembly cavity. Next, the connecting part 7 is squeezed to make the contact between the connecting part 7, the capacitor pin 4, and the inductor pin 2 tighter. Then, the connecting part 7, the capacitor pin 4, and the inductor pin 2 are all welded to the insert 6 by spot welding.
[0020] Furthermore, there are two connecting portions 7, with a gap between them. In this case, when soldering the capacitor lead 4 and the inductor lead 2 together, the two connecting portions 7 on the same insert 6 are first bent simultaneously, forming two assembly cavities between the two connecting portions 7 and the insert 6. Then, the capacitor lead 4 passes through the gap between the two assembly cavities, as shown. Figure 2 As shown, the capacitor pin 4 does not pass directly through the assembly cavity. After the capacitor pin 4 is placed, the inductor pin 2 is passed through the two assembly cavities on the same insert 6 in sequence, and the inductor pin 2 is positioned above the capacitor pin 4. Then, the connecting part 7 is squeezed to make the contact between the connecting part 7, the capacitor pin 4, and the inductor pin 2 tighter. Then, the connecting part 7, the capacitor pin 4, and the inductor pin 2 are welded to the insert 6 by spot welding.
[0021] Furthermore, the distance between the two connecting parts 7 is 1mm, which facilitates the capacitor pin 4 passing between the two connecting parts 7.
[0022] Furthermore, the sum of the widths of all the connecting portions 7 on a single insert 6 is less than the width of the insert 6.
[0023] Furthermore, the assembly cavity formed between the connecting part 7 and the insert 6 is located on the upper surface of the insert 6 to facilitate the placement of the capacitor pin 4 and the inductor pin 2.
[0024] Furthermore, the insert 6 has a through hole 8, which allows the capacitor pin 4 to move above the insert 6 through the through hole 8.
[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
