Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of power amplifier structure, can not be well and run through the problem of the components and parts compatibility that shields box body in order to solve the power amplifier structure that exists in the prior art.
Concrete, the utility model provides a kind of power amplifier structure, as shown in Figure 1, comprising: substrate 110 and shielding of no end box body 120, wherein,
No end shielding box body 120 is provided with one or more breach 121 that are complementary with side plate 130 positions and shape;
For the concrete structure that describes the power amplifier structure that the utility model provides in detail and the annexation of each parts, will do elaborating below to each parts concrete structure.
Shown in Fig. 2 A, 2B and 2C, be respectively front view, end view and the vertical view of the power amplifier structure latus inframedium that the utility model provides.
Concrete, being provided with external device connecting hole 131 in the middle of the side plate 130, this connecting hole 131 can be designed as screwed hole or other forms of hole, and this hole is wanted to connect and need be worn the fixing components and parts 140 of wall certainly.Structure chart after side plate 130 connects the components and parts 140 that need through-wall welding to connect or fix by this connecting hole 131 as shown in Figure 3.
Preferably, side plate 130 deviates from components and parts 140 to be fixed a side and is designed to nonplanar structure, to increase the tortuosity that electromagnetic wave leaks.Concrete, this nonplanar structure can be staircase structural model or other curved-surface structures etc.The utility model with the step is the structure that example illustrates side plate, and is concrete, shown in Fig. 2 A, 2B and 2C.
Further, side plate 130 can independently be made, and then is fixed on the substrate 110, also can be made as one with substrate 110, and the utility model does not specifically limit the type of attachment between side plate and substrate.
For clearer statement the utility model, the mode that side plate 130 is fixed on the substrate 110 elaborates below, as shown in Figure 4, for side plate 130 is fixed in structure chart on the substrate 110, concrete, side plate 130 is fixed in fixed form on the substrate 110 can be by screw, welding is fixed, is adhesively fixed or other modes are fixed.Illustrate that below by screw fixation method side plate 130 is fixed on the process on the substrate 110:
When side plate 130 adopted screw with substrate 110, the metal base plate 111 of substrate 110, pcb board 112 and side plate 130 were provided with screwed hole, passed metal base plate 111, pcb board 112 and side plate 130 from substrate 110 bottom sides by screw and realized that the three's is fixing.
As shown in Figure 5, be the end view of no end shielding box body 120, this no end shielding box body 120 is provided with one and the breach 121 that is complementary of side plate 130 shapes and position.This breach 121 can be provided with according to the position of side plate 130, so this breach 121 can be arranged on the sidewall all around of no end shielding box body 120, when no end shielding box body 120 is provided with branch chamber parting bead, also can be arranged on the parting bead of branch chamber.Make when no end shielding box body 120 places on the substrate 110, because no end shielding box body 120 is provided with the breach 121 that is complementary with side plate 130 positions and shape, so substrate 110, side plate 130 and do not have end shielding box body 120 and can guarantee to assemble airtight applying, the realization excellent shielding effect.Shown in Fig. 6 A, 6B and 6C, be respectively front view, end view and the vertical view of the power amplifier structure that the utility model provides.
Do simple declaration with regard to the installation process of each parts of power amplifier structure below:
When (1) installing, earlier need are worn in the external device connecting hole 131 that the fixing components and parts of wall 140 screw on the side plates 130, realized itself and tentatively the fixing of side plate 130;
(2) again side plate 130 usefulness screws are connected 112 with metal base plate 111, PCB; The side plate 130 fixing wall fixing components and parts 140 of later on need being worn are fixed with pcb board 112, and this fixed form can be welding or other forms of installing and fixing; Because also do not have this moment other structural members to interfere, it is also very convenient to operate.
(3) on the intact pcb board 112 to be installed behind required all devices, no end shielding box body 120 is installed, the breach 121 of shielding box body 120 fits tightly with side plate 130, guarantees shield effectiveness.
Certainly, the situation that above-mentioned installation process just is connected with substrate 110 non-integrals at side plate 130 is not connected 112 processes with side plate 130 usefulness screws with metal base plate 111, PCB when side plate 130 and substrate did not exist during 110 integrated connections in the above-mentioned steps (2) again.
The power amplifier structure that the utility model provides has solved the shielding box body of the power amplifier structure that present power amplifier structure adopted, and can't wear the problem that the fixing components and parts of wall weld or install to need.And the power amplifier structure that the utility model provides adopts less lateral plate structure, by adjusting the installation site of side plate, adjusts the position of breach on the shielding box body, has just realized the installation of wall-passing device spare at diverse location, is a kind of flexible and efficient installation form.And the utility model can weld components and parts or be fixed on the pcb board before load onto the shielding box body, refilled after finishing and joined shielding box.Because notch size is identical with side plate on the shielding box body, can guarantee the airtight applying of assembling, neat appearance; Simultaneously because side plate has the version of step, make that side plate and shielding box are fitted after, increased the leak tortuosity in path of electromagnetic wave in the power amplifier, big senior general has lacked electromagnetic leakage, improved the shield effectiveness of power amplifier.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
