Abstract
The utility model discloses a power supply filter with high sealing performance, which comprises a filter body and an upper cover plate. The filter body and the upper cover plate are in a full sealing structure, the filter body and the upper cover plate are in parallel seal welding connection, and the upper cover plate is a metal upper cover plate. The power supply filter with the high sealing performance has the advantages of being high in tightness, simple in structure, low in loss, high in safety and the like.
Description
Technical field
The utility model relates to a kind of power-supply filter, particularly relates to a kind of high sealing performance power-supply filter of all-sealed structure.
Background technology
Power-supply filter is exactly the electric equipment that the frequency beyond the frequency of CF in the power line or this frequency is carried out effective filtering, is widely used in the products such as computer, TV and aircraft.Existing power-supply filter generally is connected cover plate through screw with the power-supply filter body, adopt this connection can not realize the sealing fully of power-supply filter, advances moisture easily and causes die surfaces corrosion and defective chip.The power-supply filter that adopts screw to connect at present has been not suitable for current industry technology upgrade and the consumer requires increasingly high to product efficacy.
The utility model content
The purpose of the utility model is that the high sealing performance that a kind of tightness is high, simple in structure, loss is low and safe power-supply filter is provided in order to address the above problem.
The utility model is realized through following technical scheme:
A kind of high sealing performance power-supply filter comprises power-supply filter body and upper cover plate, and said power-supply filter body and upper cover plate are all-sealed structure.
As preferably, said power-supply filter body is that parallel soldering and sealing connects with said upper cover plate.Parallel soldering and sealing belongs to solder technology efficiently, and the sealing of parallel its welding of soldering and sealing is superior to stored energy welding, and it is better than Laser Welding with regard to the good outward appearance of welding efficiency.Advantages such as after adopting parallel soldering and sealing, power-supply filter has efficiently, high-air-tightness, good welds outward appearance.
As preferably, said upper cover plate is the metal top cover plate.
The beneficial effect of the utility model is:
After adopting parallel soldering and sealing, power-supply filter seals fully, and moisture can not get into product inside, has solved owing to the reason of sealing is brought performance of products decline.After adopting parallel soldering and sealing, the power-supply filter surface is except leading-out terminal, and remainder has no ridge and connector, and its profile is superior to the power-supply filter of other packaged type.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model;
Among the figure: 1-power-supply filter body, 2-upper cover plate, 3-fixed head, 4-fixing hole, 5-input terminal, 6-lead-out terminal, 7-earth terminal, 8-silver coating.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As depicted in figs. 1 and 2; The utility model high sealing performance power-supply filter comprises power-supply filter body 1, upper cover plate 2 and fixed head 3; Be provided with circuit board in the power-supply filter body 1, fixed head 3 is provided with fixing hole 4, and fixed head 3 is one-body molded with power-supply filter body 1; One side of power-supply filter body 1 is provided with two input terminals 5; Input terminal 5 is connected with outside power supply through lead, and the opposite side of power-supply filter body 1 is provided with two lead-out terminals 6 and an earth terminal 7, and power-supply filter body 1 is an all-sealed structure with upper cover plate 2.As preferably, power-supply filter body 1 is that parallel soldering and sealing connects with upper cover plate 2.After adopting parallel soldering and sealing, power-supply filter seals fully, and moisture can not get into product inside, has solved owing to the reason of sealing is brought performance of products decline.In addition, adopt parallel soldering and sealing after, the power-supply filter surface is except leading-out terminal, remainder has no ridge and connector, its profile is superior to the power-supply filter of other packaged type.As preferably, the upper cover plate 2 in the present embodiment is the metal top cover plate, and the inwall of upper cover plate is provided with one deck silver coating 8, and the thickness of silver coating 8 is 5-10 μ m.Said silver coating can shield inner electric current effectively, when power-supply filter leaks electricity, can play the certain protection effect.
Claims (3)
