Abstract
The utility model discloses a LC wave filter that antidetonation was moved, LC wave filter include paster electric capacity, inductance, filter circuit board and shielding cavity, paster electric capacity and induction soldering at the filter circuit board, filter circuit flange reason is equipped with the draw -in groove, the draw -in groove gilding of borduring, the shielding cavity is equipped with the card foot to through calorie foot card in the draw -in groove of filter circuit board, weld between card foot and the draw -in groove. The utility model discloses LC filter configuration not only structure is small and exquisite, can use in adverse circumstances, has the antidetonation function, can also adapt to large -scale production.
Description
Technical field
The utility model relates to the filtration module field in communication system, particularly relates to miniaturized antidetonation band and leads to LC filter.
Background technology
Along with extensive use and the development of the communication technology, people to the miniaturization of the communication technology and integrated requirement more and more higher.Filtration module is as the requisite part of communication system, and its miniaturization has vital effect to communication system.Although the filtration module of current use can meet miniaturized demand, the reliability worked under severe conditions is inadequate, have impact on the normal work of whole electronic equipment.
Utility model content
Technical problem to be solved in the utility model is the LC filter realizing a kind of miniaturization and have function of seismic resistance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of LC filter of anti-vibration, LC filter comprises patch capacitor, inductance, filter circuit plate and shielding cavity, described patch capacitor and induction soldering are at filter circuit plate, described filter circuit panel edges is provided with draw-in groove, and described draw-in groove bound edge is gold-plated, and described shielding cavity is provided with card base, and being stuck in the draw-in groove of filter circuit plate by card base, described card base welds with between draw-in groove.
Glue is filled with between described filter circuit plate and shielding cavity.
The enamelled wire of described inductance is fixed by glue.
Described shielding cavity both sides are provided with and prevent interference and the diagonal angle for injecting glue from dodging opening.
The glue of filling between described filter circuit plate and shielding cavity is AB glue, and the glue of fixed inductance enamelled wire is that D05 is gluing glutinous.
The utility model LC filter construction not only compact structure, can use in adverse circumstances, have function of seismic resistance, can also adapt to large-scale production.
Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in the utility model specification below and figure is briefly described:
Fig. 1 is filter circuit plate structure schematic diagram;
Fig. 2 is shielding cavity structural representation;
Fig. 3 is the right view of shielding cavity shown in Fig. 2.
Mark in above-mentioned figure is: 1, filter circuit plate; 2, draw-in groove; 3, shielding cavity; 4, card base; 5, opening is dodged at diagonal angle.
Embodiment
The LC filter of the utility model anti-vibration comprises patch capacitor, inductance, filter circuit plate 1 and shielding cavity 3.As shown in Figure 1, filter circuit plate 1 edge is provided with draw-in groove 2, draw-in groove 2 quantity and size set according to shielding cavity 3, generally arrange eight, and all bound edge is gold-plated for each draw-in groove 2, for welding with filter circuit plate 1, as shown in Figure 2,3, shielding cavity 3 is provided with card base 4, and is stuck in the draw-in groove 2 of filter circuit plate 1 by card base 4, weld between card base 4 with draw-in groove 2 after fixing, thus reduce the impact shaking and cause.
Inductance generally selects magnet ring inductance, finally determine the number of turns of enamel-cover wire-wound magnetic core and the density degree of enamelled wire, smear fixing uniformly with D05 glue, after the glue solidifies, inductance and patch capacitor are welded on filter circuit plate 1 with 320 DEG C of high temperature solder sticks on temperature 150 DEG C of high-temperature stages according to layout.
For improving function of seismic resistance further, the diagonal angle to shielding cavity 3 both sides is dodged opening 5 place and is injected AB glue, utilizes the gap between AB glue filling filter circuit plate 1 and shielding cavity 3, makes the LC filter of anti-vibration work more reliable and more stable under severe annular.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
