Problems solved by technology

[0002] At present, welding is usually used to directly weld the pins on the high-current inductor to the externally connected installation circuit. The wire pins are particularly long and it is not easy to solder.
Due to the large current of the high-current inductor, the cross-sectional area of ​​the wire is also large, up to 15mm 2 , or even larger, making the pins weak, difficult to solder, and poorly connected to the circuit, easy to loosen and fall off and have false soldering, which affects the yield and the working state of the inductor, and the circuit space utilization rate is poor

Embodiment 1

[0016] Such as figure 1 , a high-current inductor, including an inductor body 1, the inductor body 1 is provided with a pin 3 connected to a circuit board 2, and a connecting device is provided between the pin 3 and the circuit board 2. The connecting device includes a buckle 4 arranged at the end of the pin 3, a screw hole 5 corresponding to the buckle 4 on the circuit board 2 and a screw 6. Put the buckle 4 on the screw hole 5, and the screw 6 passes through The buckle 4 is connected with the screw hole 5 to fix the buckle 4. It is easy to install, has good firmness, and does not need welding, which improves the installation speed. The buckle 4 and the pin 3 are integrally structured. Directly by the pin 3 The ends are bent to save material.

Embodiment 2

[0018] Such as figure 2 , a large current inductor, comprising an inductor body 1, the inductor body 1 is provided with a pin 3 connected to a circuit board 2, and a connection device is provided between the pin 3 and the circuit board 2. The connecting device includes a terminal 7 arranged at the end of the pin 3 , and a terminal hole 8 arranged on the circuit board 2 corresponding to the terminal 7 . The terminal 7 is directly fixed with the terminal hole 8, and the installation speed is fast. The terminal 7 is welded on the pin 3 by means of welding.

Embodiment 3

[0020] Such as image 3 , a large current inductor, comprising an inductor body 1, the inductor body 1 is provided with a pin 3 connected to a circuit board 2, and a connection device is provided between the pin 3 and the circuit board 2. The connecting device includes a plug-in piece 9 arranged at the end of the pin 3 , and a plug-in interface 10 corresponding to the plug-in piece 9 arranged on the circuit board 2 . Insert the plug piece 9 into the socket 10 for fixing.

Abstract

The invention provides a high-current inductor, which comprises an inductor body. The inductor body is provided with a pin connected with a circuit board, and a connection device is arranged between the pin and the circuit board. The high-current inductor can lead the inductor and the circuit board to be connected and installed conveniently, and has good firmness and difficult loosening and dropping.

Description

technical field [0001] The invention relates to a large current inductor. Background technique [0002] At present, welding is usually used to directly weld the pins on the high-current inductor to the externally connected installation circuit. The wire pins are particularly long and are not easy to weld. Due to the large current of the high-current inductor, the cross-sectional area of ​​the wire is also large, up to 15mm 2 , or even larger, making the pins weak, difficult to solder, and poorly connected to the circuit, easy to loosen and fall off and have false soldering, which affects the yield and the working state of the inductor, and the circuit space utilization rate is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-current inductor, which can make the connection and installation of the inductor and the circuit board convenient, and has good firmness and is not easy to loosen and fall off. ...
