Description

Single type radome
Technical field
The utility model relates to a kind of screening arrangement, particularly a kind of single type radome.
Background technology
Along with the development of the communication technology, the utilization of wireless radio frequency circuit technology is more and more wider, and nowadays, the electronic equipments such as computer, mobile phone, camera have become articles for use indispensable in people's daily life.Radio circuit in electronic equipment operationally often can send frequency electromagnetic waves, and may produce interference to the normal work of electronic product, cause temporary malfunction, What is more, causes device damage.In order to reduce the electromagnetic interference between radio frequency part and other parts; prior art can add radome usually in the PCB of electronic equipment; be around in radome by needing the components and parts of conductively-closed; radome is slotted, presses down the bottom of this slotted section to radome; weld together with PCB; obtain a folded walls, radio circuit is sealed in radome, thus realize reducing the object of radio circuit and other partial circuits electromagnetic interference each other.But also just because of the existence of this fluting, other parts in PCB are still communicated with the external world, fail the effectively isolated electromagnetic interference from external devices, effectively can not improve the antijamming capability of circuit itself.
Utility model content
The purpose of this utility model is to provide a kind of single type radome, when it being added be located in PCB, can not only signal disturbing between shielded radio frequency circuit and other partial circuits, more effectively can completely cut off the electromagnetic interference that other partial circuits are subject to from external devices simultaneously, again because this radome is single type radome, easy for installation, save human cost.
For solving the problems of the technologies described above, execution mode of the present utility model provides a kind of single type radome, be located in PCB, this radome comprises a metal cap body and conductive layer, metal cap body body is a frame structure, comprise: for enclose around conductively-closed components and parts in the four sides tegmental wall of closed circular and a caping be fixedly linked with the top of tegmental wall, caping is provided with a fluting, press down slotted section the end of to, weld together with PCB, define a folded walls, this conductive layer is located on the caping of metal cap body, shelter from the opening because described fluting is formed.
The utility model in terms of existing technologies, utilizes above-mentioned single type radome can not only effectively reduce interference between radio circuit and other partial circuits, can also strengthen the antijamming capability of self.Above-mentioned metal cap body is welded in PCB, needing in the components and parts of shielding are all around in, caping are established a fluting, presses down otch and be connected with PCB and constitute a folded walls, thus define a closed space, to be closed by radio circuit; Conductive layer is located on the caping of metal cap body.Above-mentioned metal cap body and conductive layer constitute single type radome of the present utility model, and wherein, the existence of folded walls in metal cap body, effectively shields the electromagnetic interference of radio frequency part to other partial circuits; The conductive layer be located on the caping of metal cap body then effectively can shield the interference that external devices produces other partial circuits, thus further improves shield effectiveness; On the other hand, because this radome is single type, install more for convenience, save human cost.
Further, conductive layer comprises glue and metal label paper, and glue is coated on caping outer surface, and metal label paper is pasted on caping by glue.Label paper all can be pasted with glue in the surface of existing chip, is used for recording the information such as manufacturer's title, date, and label paper is then replaced with metal label paper by execution mode of the present utility model, does not increase technique, and ensure that the thickness of whole device.Because metal has the characteristic of electromagnetism interference, the single type radome that glue, metal label paper and above-mentioned metal cap body are formed can be used for strong signal to external world and carry out Isolated Shield.
Further, glue is conducting resinl.Wherein, conducting resinl is the adhesive that can conduct electricity, and is widely used in electronic applications.By conductive glue on the outer surface of the caping of metal cap body, metal label paper is located on conducting resinl, is pasted on caping by conducting resinl.Because conducting resinl and metal label paper all have the effect of shield electromagnetic interference, the conductive layer utilizing them to form is whole to be covered on the caping of metal cap body, the otch that caping exists is closed, other parts are hedged off from the outer world come, thus more effectively can shield extraneous strong signal to the impact of other parts.
Further, metal label paper bag is containing label paper and electroplated metal layer.Electroplated metal layer is label layer, can be designed as arbitrary shape, is plated on optional position on label paper.
Further, electroplated metal layer is only coated in fluting position.Because external environment condition is communicated with other parts by fluting, thus other parts are had an impact, so only at fluting position coating electroplated metal layer, just effectively need can prevent outside strong signal from producing interference to other parts, save material and human cost.
Further, in the components and parts that fluting position is corresponding, the slotting position corresponding to part components and parts is coated with conductive glue and electroplated metal layer not.Because metal label paper has tension force, of long duration easily to stay, and circuit board exists a lot of components and parts, the position of some components and parts is higher, the higher components and parts in some positions, otch place may be caused like this to contact with the metal label paper stayed and to produce short circuit, affect its result of use, so this thing happens in order to avoid, at place not coated with conductive glue and the electroplated metal layer of the higher components and parts in location, otch place.
Further, conductive layer comprises conducting resinl and label paper, and label paper is pasted on caping by conducting resinl.Because conducting resinl can conduct electricity, there is the effect of electromagnetism interference, therefore, it is possible to the interference of strong signal forms certain shielding action to external world.
Further, conductive layer comprises conducting resinl, sheet metal and label paper, and sheet metal is pasted on caping by conducting resinl, label paper by conducting resinl and sheet metal glued together.The conductive layer utilizing sheet metal, label paper and two-layer conducting resinl jointly to form, is located on the caping of metal cap body, can obtain better shield effectiveness.
