Problem, while upper and lower capacitor board dispatch from foreign news agency interpolar design electrode rod structure is, it can be achieved that capacitor board external electrode intercommunication up and down, reinforces connecing
Ground reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: the upper capacitor board of 1-, 2- magnetic core, 3- electrode column, capacitor board under 4-, 5- contact, 51- π type filtering unit.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of filtering unit of electric connector, including magnetic core 2；The side of the magnetic core 2 is equipped with upper capacitor
Plate 1, the other side are equipped with lower capacitor board 4, are connected between the dispatch from foreign news agency grade of upper capacitor board 1 and the dispatch from foreign news agency grade of lower capacitor board 4 by electrode column 3
It connects, realizes intercommunication, reinforce Earthing Reliability；Several contacts 5 are equidistantly equipped in the upper capacitor board 1 and lower capacitor board 4；Institute
Stating contact 5 is jack or contact pin type structure contact, and the tail end form of contact 5 is straight cutting, bend cutting, welds in cup structure form
One kind.
The upper capacitor board 1, magnetic core 2, lower capacitor board 4, contact 5 weld to form modular π type by hot air reflux
Filtering unit 51.
It is clearance fit between the magnetic core 2 and contact 5.
It is fixed between the upper capacitor board 1, lower capacitor board 4 and contact 5 by scolding tin.
The upper capacitor board 1, electrode column 3, lower capacitor board 4,5 connecting portion even application of contact have solder(ing) paste.
Several inner holes are equipped in the upper capacitor board 1 and lower capacitor board 4, contact 5 is mounted in inner hole.
The both ends of the upper capacitor board 1 and lower capacitor board 4 are respectively equipped with preformed hole, and electrode column 3 is mounted in preformed hole.
