Fig. 3 is Fig. 2 partial enlarged drawing.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
As shown in Figure 1 and Figure 2, the filter apparatus based on can gluing cover plate of the present embodiment, comprise filter cavity 5 and cover plate assembly, described cover plate assembly is arranged on filter cavity 5, also comprise and cover copper layer 2, composite panel 3, self-clinching nut 4, tuning self-locking screw 1, described two surfaces up and down of covering copper layer 2 and arranging composite panel 3, described self-clinching nut 4 is arranged on composite panel 3, described tuning self-locking screw 1 is connected with self-clinching nut 4 by screw thread, and whole composite material cover plate 3 is fastened on the cavity 5 of filter by conductive silver glue 6.
Cover plate in the present embodiment is for covering composite copper material flitch, and the object of covering copper is the conductivity in order to ensure upper and lower two surfaces of cover plate, makes cover plate and filter cavity be linked to be an entirety, the object being grounded.The more traditional aluminium sheet of composite panel has that quality is light, price is low, material evenness advantages of higher, therefore can be used as the substitute of conventional cover plate.
Self-clinching nut 4 in the present embodiment is to adopt Reflow Soldering or other welding manners to be welded to cover on composite copper material flitch 3, instead of adopts the mode pressing.Due to traditional mode that presses, can cause cover plate to produce moderate finite deformation, in order to adjust its planarization, meet the requirement of electromagnetic shielding, prevent electromagnetic leakage, need a large amount of trip bolts that cover plate is flattened, and be fastened on cavity, meanwhile, also need on cavity wall, be provided with corresponding a large amount of screw hole, so greatly increase difficulty and the CNC(Digit Control Machine Tool of design) workload of processing, the cost of whole filter, weight are increased.The mode that adopts welded nut, because welding temperature is lower, the deflection that covers composite copper material flitch 3 is very little, and the evenness of cover plate meets instructions for use.Again cover plate 3 and filter cavity 5 are fixed up by the gluing mode of conductive silver glue, have so both ensured the reliability connecting, improved again the sealing of whole device.Adopt described cover plate that can be gluing, can be by the trip bolt cancel all between composite panel 3 and filter cavity 5, thus reduce design and the processing and manufacturing cost of filter cavity, cover plate, alleviate weight, improve the competitiveness of product in market.
