Embodiment
With reference to Figure of description to explanation at length below the work of the present invention.
Filter array plate of the present invention; Its processing and fabricating is very simple and convenient; Shown in the by specification accompanying drawing; Filter array plate is made up of insulation board 7, feedthrough capacitor 5 and PCB circuit board; Making step is following: with thin-sheet metal bound edge 6, open hole in the centre of insulation board 7 at the periphery of insulation board 7, the pin 4 of feedthrough capacitor 5 passes in the through hole in the middle of the insulation board 7 and is fixed together with insulation board 7 encapsulation; The pin 4 that is arranged on feedthrough capacitor 5 two sides is connected with external electric PCB circuit board 3 with the internal electrical PCB circuit board 8 that is provided with internal circuit 9 and external circuit 2 respectively, on internal electrical PCB circuit board or external electric PCB circuit board, also is provided with to touch mouse interface 1.
The design of metal bound edge frame; Utilize insulating material effectively to encapsulate the feedthrough capacitor of selecting fixing; Guaranteeing that feedthrough capacitor plays on the basis of good filtering performance, also guaranteeing the shielding properties of whole filter array plate simultaneously, for satisfying various structure demand in the application; This filter array plate can accomplish that under the prerequisite of guaranteed performance minimum package dimension is the 2.54mm spacing; Packaging satisfies big electric current demand, and the single pin maximum can satisfy the electric current demand of 5A, conveniently in the environment strict to big current requirements, uses.
The metal that metallic plate bound edge 6 uses is Copper Foil or aluminium foil, and joint must connect can not be gapped.
The limit portion that is positioned at insulation board 7 also is provided with fixedly ear 10 with holes.
And this technological invention has also that the optional then property of electric capacity reaches packing forms by force and overall dimension can change various characteristics, is fit to the use of different field, and the signal input and output that especially are fit to have extensive stitch device connect.
Concrete design objective is following:
1. rated voltage: 100VDC;
2. operating current: 5A;
3. working temperature :-55 ℃～+ 85 ℃;
4. standard electric capacity: 820PF; (optional);
5. insulation resistance: >=4000M Ω/100VDC;
6. proof voltage intensity: 250VDC/6S;
The installation of PCB circuit board avoids adopting the mode of soldered wires to connect, and can effectively improve the performance of electromagnetic compatibility.Internal circuit and external circuit are installed with interior circuit PCB circuit board or dispatch from foreign news agency PCB circuit board respectively and then be connected with filter array plate, and guarantee the fastness that connects.After connecting shielded metal frame and shielding body are fixed and got final product.The outside also can connect other equipment such as touching mouse uses, and makes things convenient for expanded function.
Environment and protection design thereof: wide temperature service condition is satisfied in design, for satisfying the high demand that connects the environment that discharges water, applies prevention material at the interface unit face, effectively improves NBC protective performance.
Filter array plate of the present invention can be widely used in various electronic products, such as being applied to space flight, aviation, military equipment, telecommunication equipment, communication base station, GPS, wireless telecommunications, CDMA, radar, microwave communication, data communication, computer, electromedical equipment or the like.Can solve various electronics compatibling problems well.
