A kind of radome and a kind of assembly

Technical field

The utility model relates to communication technical field, particularly a kind of radome and a kind of assembly.

Background technology

Radome has obtained increasing application as important device in the portable terminal product.The effect one of radome is to prevent that extraneous space radiation and ESD (Electro Static Discharge, static discharges) discharge from producing CPU (Center Process Unit, central processing unit) and disturbing.Another effect of radome is can suppress circuit externally to produce other equipment operate as normal of radiation effect, can also provide good ground connection effect to reduce impedance ground to complete machine.The kind of radome mainly comprises dismountable type radome and integrated shielding cover at present, and the dismountable type radome mainly is made up of mask frame and screening cover.Now, the miniaturization of portable terminal product causes the veneer layout density to strengthen, and needs the part of shielding to increase, and considers the problem of producing maintenance, and prior art mainly adopts the dismountable type radome.But the connection effect of the positive and negative radome of existing dismountable type radome is relatively poor, shield effectiveness is undesirable.

At present, the various functional units of electronic equipment have all been made modular form, a plurality of modules can be assembled on the motherboard according to product form and function needs, thereby form electronic equipment miscellaneous.

Now, module mainly is connected by the mode of welding or connector with motherboard.Specific implementation is: reserve pad on module and motherboard, module is welded direct on the motherboard; Perhaps, on module and motherboard, reserve connector, realize being electrically connected by FPC (Flexible Printed Circuits Board, flexible printed circuit board) or cable.

But welding manner need increase Reflow Soldering, and not easily-disassembled and maintenance is difficult in maintenance.The connector mode need increase connector, has increased veneer area and Material Cost.

Summary of the invention

The utility model embodiment provides a kind of radome, to realize strengthening the effect that is connected of first screening cover and secondary shielding lid, strengthens the shield effectiveness to the internal circuit of veneer; The embodiment of the invention provides a kind of assembly, to reduce the welding link, saves connector, reduces Material Cost, reduces arrangement space.

For achieving the above object, the utility model embodiment provides a kind of radome on the one hand, comprising: first screening cover, secondary shielding lid and intercell connector, described first screening cover is connected by described intercell connector with the secondary shielding lid.

On the other hand, the utility model embodiment provides a kind of assembly, comprise: module and motherboard, described module is fixed on the described motherboard, described module bottom surface has first connector, and described motherboard has second connector, after described module is fixed on the described motherboard, described first connector contacts with second connector, realizes being electrically connected of described module and described motherboard.

Compared with prior art, the utility model embodiment has the following advantages: the radome that the utility model embodiment provides, by intercell connector first screening cover and secondary shielding lid are linked together, strengthened shield effectiveness, and reduced the impedance ground of veneer the internal circuit of veneer.The assembly that the utility model embodiment provides utilizes shell fragment to realize being electrically connected of module and motherboard, has reduced the welding link, make things convenient for follow-up reprocessing and safeguarding, and saved connector, reduced Material Cost, reduced arrangement space, made the size of module can do forr a short time.

Description of drawings

In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The structure chart of a kind of radome that Fig. 1 provides for the utility model embodiment;

The structure chart of a kind of assembly that Fig. 2 provides for the utility model embodiment.

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 a part of embodiment of the present utility model, 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.

As shown in Figure 1, the structure chart of a kind of radome that provides for the utility model embodiment, the radome that the utility model embodiment provides is the dismountable type radome, this dismountable type radome comprises first screening cover 11, secondary shielding lid 12 and intercell connector 13.Wherein, first screening cover 11 is positive screening cover, and secondary shielding lid 12 is the screening cover of reverse side; Perhaps, first screening cover 11 is the screening cover of reverse side, and secondary shielding lid 12 is positive screening cover.But the utility model embodiment is the screening cover in front with first screening cover 11, and secondary shielding lid 12 is that example describes for the screening cover of reverse side.

First screening cover 11 and the radome of secondary shielding lid 12 by an integral type of intercell connector 13 formation of increase, and the mask frame of positive and negative is constant.Do like this and original positive and negative non-touching screening cover can be linked together by metallization intercell connector 13, increased the effect of bonding, avoided (PrintedCircuit Board at PCB, printed circuit board (PCB)) the abundant ground connection of the radome that causes owing to design reasons in the design causes radome to float the problem on ground.

Among the utility model embodiment, the number of intercell connector 13 and width can be according to the settings of concrete application scenarios, and the number of intercell connector 13 and the value of width do not influence the realization of the utility model embodiment.

And first screening cover 11 of the utility model embodiment and secondary shielding lid 12 are nearer apart from the edge of veneer, make 13 of intercell connectors need the less curvature of bending can realize being connected of first screening cover 11 and secondary shielding lid 12.
