Abstract
The utility model relates to a common mode inductance coil which comprises a frame, a magnet core and a coil. The frame is provided with a transverse through hole. The magnet core is inserted into the through hole. The coil comprises a first coil and a second coil. A first insulating plate, a second insulating plate and a third insulating plate are arranged on the frame, the first coil is located between the first insulating plate and the second insulating plate and wound on the frame, the second coil is located between the second insulating plate and the third insulating plate and wound on the frame, seal terminals are arranged on two sides of the bottom of the frame, guide pins are symmetrically arranged on the seal terminals, and the guide pins are connected with the corresponding coils. The common mode inductance coil has the advantages that the common mode inductance coil is resistant to high temperature, low in efficiency, low in distributed capacitance and high in quality factor; in addition, the common mode inductance coil is light in weight, stably fixed, convenient to mount and demount and highly practical.
Description
Technical field
The utility model relates to a kind of common mode inductance coil.
Background technology
due to advancing by leaps and bounds of high-tech technology in recent years, especially make rapid progress especially in the field of microelectronics correlation technique processing procedure, so the electronic correlation product has goed deep into each family, and in all trades and professions, become an indispensable part in the modern life, certainly because human wants is more and more, relatively make electronic installation must reach the use of greater functionality, electronic product is strided forward towards the target of diversification effect, along with various electronic equipments, TV network, switch, mobile communication equipment and office automation day by day universal, electromagnetic environment in electronic system becomes increasingly complex, the electromagnetic interference phenomenon is day by day serious, and become the obvious obstacle that affects system's normal operation, phenomenon for shield electromagnetic interference, people use common mode inductance mostly, but existing common mode inductance coil efficiency is low, and distributed capacitance is large, quality factor are low, this coil is fixing unstable in addition, install inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of common mode inductance coil, to overcome at present existing inductance coil above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of common mode inductance coil, comprise skeleton, magnetic core and coil, described skeleton is provided with cross through hole, described magnetic core is plugged in through hole, it is characterized in that: described coil comprises coil one and coil two, described skeleton is provided with insulation board one, insulation board two and insulation board three, described coil one is wrapped on skeleton between insulation board one and insulation board two, described coil two is wrapped on skeleton between insulation board two and insulation board three, described skeleton two bottom sides is provided with hermetic terminal, be arranged with on hermetic terminal and draw pin, draw pin and connect with corresponding coil.
Further, described insulation board is the PVC material.
Further, described coil is wrapped with insulating tape.
The beneficial effects of the utility model are: the utility model provides a kind of common mode inductance coil, and this coil is high temperature resistant, efficient is high, and distributed capacitance is little, quality factor are high, and this common mode inductance coil weight is light in addition, fixing-stable, install, dismounting is all very convenient, practicality is very strong.
