Specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing Each embodiment of type is explained in detail.However, it is it will be understood by those skilled in the art that each in the utility model In embodiment, in order that reader more fully understands that the application proposes many ins and outs.But, even if there is no these skills Art details and the many variations based on following embodiment and modification are it is also possible to realize the application technical side required for protection Case.

First embodiment of the present utility model is related to a kind of radome, and as shown in figures 2-3, this radome comprises：Cover lid 1 and the cover wall 2 that is connected with cover lid 1, wherein, cover lid 1 offers the receiving hole for accommodating heat conductive pad 3, sets on cover lid 1 It is equipped with the conductive part 4 for conflicting with metal shell.

It should be noted that in the present embodiment, conductive part 4 can be conflict angle, and above-mentioned conflict angle is connected with cover lid 1 Reach the effect of shielding with the contact realized with metal shell.But, conductive part 4 can also be other conducting mediums, such as may be used To be the conducting mediums such as conducting resinl, conducting foam or conductive fabric, you can so that above-mentioned conducting medium is fixed on cover lid 1 and metal-back So that radome can be connected to realize the effect shielding by conducting medium with metal shell between body.Present embodiment should not As limit, those skilled in the art can flexibly select the way of contact of conductive part and cover lid according to actual needs.

In order to be able to make radome sufficiently contact with fore shell, to realize more preferable shield effectiveness, in the present embodiment, support Feeler can uniformly be arranged at the periphery of receiving hole, and certainly, conflict angle can also otherwise be arranged on cover lid 1, this Embodiment should not be as limit.

During actual preparation cover lid, for making cover lid 1 and conflict angle can produce by same mould, save and make Material, in the present embodiment, cover lid 1 and conflict angle can be integrally formed, and certainly, cover lid 1 and conflict angle can also be by welderings The mode such as connect connects, and present embodiment should not be as limit.

In the assembling process of whole machine, dry in order to prevent the signal that baseband chip produces from the other assemblies on mainboard are produced Disturb, radome is generally with covering on baseband chip it is well known that in the use of whole machine, baseband chip can produce a lot Heat, if these heats pass not in time, will cause very big impact to the use of whole machine, even result in whole machine Damage, so heat conductive pad can be installed on baseband chip by manufacturer, make heat conductive pad pass through receiving hole can contact with metal shell, And then the heat transfer producing baseband chip, on metal shell, reaches the effect of radiating.In addition, in order that receiving hole is more preferable Receiving heat conductive pad, in the present embodiment, receiving hole can with square receiving hole, it is of course also possible to the receiving hole of other shapes, Present embodiment should not be as limit.
