Background technique

In many electronic devices, the circuit or device itself will generate a certain amount of electromagnetic interference, especially electronic devices are gradually becoming smaller, and multiple electronic components are tightly packed together, which is more prone to electromagnetic interference problems. Excessive electromagnetic interference will interfere with the normal operation of other surrounding electronic devices, or cause mutual interference with other electronic devices. In electronic equipment, inductors are often used. They are commonly used anti-interference components in electronic circuits. They have a good shielding effect on high-frequency noise and can be used for anti-interference filtering and energy storage.

The electromagnetic coil on the existing part of the magnetic ring inductance will be used in conjunction with the bottom plate and the partition plate. The assembly of the bottom plate and the magnetic ring body is to first insert the lead pins of the magnetic ring into the bottom plate, and then dispense glue. Glue the bottom plate to the lower part of the magnetic ring body, and glue the partition plate to the inside of the magnetic ring body by dispensing glue. However, after dispensing, the partition, the bottom plate and the magnetic ring body are connected as an inseparable one. When the electromagnetic coil is in use, the wire is broken or the wire is burned. The installation bottom plate cannot be disassembled, and the insulating tube used for winding the wire is an integral annular structure, so it will be very difficult to remove the wire on the insulating tube for recycling. In the prior art, in order to reduce unnecessary Trouble, when the coil is damaged or burned, it is directly discarded. The copper core in the wire is relatively expensive, and direct discarding will obviously cause waste. Directly discarding the installation bottom plate and insulating tube will also cause waste. At present, the cost of raw materials is high. In a large environment, such waste will greatly increase the production cost of enterprises. At the same time, due to the need to complete the dispensing process of the bottom plate and the magnetic ring body, the magnetic ring body production line must also be equipped with a partition retaining fixture, bottom plate retaining fixture equipment, glue dispensing equipment and glue dispensing drying equipment. The equipment cost of the enterprise And the cost of production line design will be very high.

Therefore, in the current environment of high raw material costs, difficult overall industrial development and low benefits, a magnetic ring inductor with a partition and bottom plate connected without glue is designed to reduce the glue dispensing process and reduce the production loss and waste of enterprises. , It is necessary to reduce the overall production cost of the enterprise and improve the economic benefit of the enterprise.
