Technical field
It is used to accommodate the housing of printed circuit board (PCB) and a kind of electrical equipment the present invention relates to a kind of.
Background technology
JP-2002176308 A describe a kind of radio device for being used for the vehicle with antenna, which arrives
In the housing being made of synthetic resin.
The content of the invention
In this background, proposed using the present invention and a kind of be used for printed circuit board (PCB) according to independent claims
Housing and a kind of electrical equipment.Favourable designing scheme is given by each dependent claims and subsequent explanation.
If the housing for the printed circuit board (PCB) with antenna area is equipped with antenna cavity, antenna area can be with cloth
Put outside the outer wall of housing, and the central area of printed circuit board (PCB) can be arranged within the outer wall of housing.
Advantageously it is possible thereby to so select the size of housing, i.e. housing extends on whole printed circuit board (PCB), wherein day
Line region can also still be arranged in hull outside due to may be designed to the antenna cavity of recess.For example, the covering surface of housing, such as
There can be a kind of size parallel to the surface of shell of printed circuit board arrangement, it is approximate or corresponds exactly to entirely printing electricity
The size of road plate.For example, this covering surface can be slightly larger than the entire surface of printed circuit board (PCB).It is possible thereby to by printed circuit board (PCB)
The region outside the antenna area be arranged within the side wall of housing, and antenna area can be covered by covering surface.
In other words, housing can be bounced back or is slotted（aussparen）, it is used on printed circuit board (PCB) one to realize
Or the room of mutiple antennas.Here, the size of printed circuit board (PCB), hereinafter also referred to circuit board can be big less than or equal to housing
It is small, and can also be protruded from housing.
Therefore, in the electrical apparatus in order to realize that outside radiation need not plug antenna as external module, or will
Printed circuit board (PCB) zone location with antenna is outside maximum shell dimension.That is, printed circuit board (PCB) is not necessarily designed to
It is local to be more than housing basal plane, and the housing basal plane need not be stretched out.Therefore, printed circuit board (PCB) can be designed to be equal to or less than housing
Basal plane.Basal plane can not be known as the face surrounded in the height of printed circuit board (PCB) by housing herein, but be properly termed as housing and exist
Covering surface or perspective plane in printed circuit plate face.The perspective plane can pass through parallel throwing of the housing in printed circuit plate face
Shadow obtains.Here, the projection beam of parallel projection can extend perpendicular to printed circuit plate face.Therefore, perspective plane can by

Figure 10 with solid show it is according to an embodiment of the invention, there is the electric of two housing parts 102,1002
Equipment 100.According to this embodiment, housing parts 102,1002 are respectively corresponding to the housing shown in Fig. 3.Housing parts 102,
It is arranged in the plane of printed circuit board (PCB) 104 1002 mirror images.Printed circuit board (PCB) 104 is arranged in housing parts 102,1002
Between.Antenna cavity 106 supplements into the symmetrical reflector for antenna structure 110.It can realize what is clearly shown by reflector
Directional characteristic 202.The housing parts of the protrusion that reflector and printed circuit board (PCB) 104 pass through housing are protected come 102,1002.
Figure 11 shows electrical equipment 100 that is according to an embodiment of the invention, having two housing parts 102,1002.
Electrical equipment 100 corresponds to the electrical equipment in Figure 10.Compared with electrical equipment in Fig. 3, radiation characteristic 202 is from antenna area
112 downwards and show downwards.
Figure 12 with solid show according to another embodiment of the invention, there are two housing parts 102,1002
Electrical equipment 100.Housing parts 102,1002 correspond to the housing in Fig. 4 at this.Housing parts 102,1002 can be right each other
It is arranged in the plane of printed circuit board (PCB) 104 with claiming ground or in the same manner composition and mirror image.Housing parts 102 are housing uppers, separately
One housing parts 1002 is lower housing portion.Printed circuit board (PCB) 104 is arranged in the board layer of centre, board layer arrangement
Among housing parts 102.Each two antenna cavity 106 supplements into the symmetrical reflector for each antenna 110.By anti-
Emitter can realize the directional characteristic 202 clearly shown or radiation characteristic.Reflector and printed circuit board (PCB) 104 pass through housing section
The rib of the pendency of part 102,1002 is protected.
According to the principle that Fig. 2 to 12, in the embodiment of shell variation below based on it is identical all the time into
Row description.According to the principle, printed circuit board (PCB) or circuit board 104 are not more than shell dimension.Electricity is printed on as copper or golden conducting wire
The radiation characteristic 202 of antenna 110 on road plate 104 is without prejudice.EMV leakproofness inwardly or outwardly is also ensured at the same time.
Do not have to meet the premise in the case of additional component yet.
For example, Fig. 4 shows the housing 102 that form is enclosure slot, its middle front part corner folds inward or bends.By bending
Or fold and generate " exposing " board area 112, antenna 110 is on the board area 112.Forming the knot in corner
Long gap portion 600 is not produced in structure, electromagnetism wave energy is entered or sent by gap portion.The length of the permission in gap portion 600 depends on out
Existing frequency.It is applicable in principle to be：Avoid gap portion 600, or gap portion be designed as far as possible it is small.For example, this can lead to
Cross the lug of two folded/bents（Lappe）Teeth portion realize, as figure 6 illustrates as.It can see in figures 7 and 8 logical
The possibility that possibility that lap over is realized, that gap portion is avoided in other structures or gap portion minimize.
In order to which with " system of sealing ", housing 102 is closed by case lid 200.The anterior corner of lid 200 is same
Formed, i.e., form circuit board triangle 112 on the printed circuit board (PCB) side.In order to protect " free " board area 112
From mechanical influence or protect it from being damaged, it is reasonable to which as showing in Fig. 5, form is to cover made of plastics
500 protection circuit plates region of housing.
Figure 3 illustrates housing 102, wherein with the difference that is shown in Fig. 4, housing 102 has not only been folding or bending over
Corner, and it has been folding or bending over whole front area 108.Therefore, printed circuit board (PCB) 104 in the modification not only in corner portion
Exposed with triangular shape, and exposed on whole front width.Therefore this solution provides selection, i.e., not only antenna 110 positions
In corner portion, and if necessary to also located mutiple antennas on whole circuit board width.
Figure 10,11 and 12 show the possible modification of the housing 102 shown in Fig. 2 to 5.The shape and knot of housing 102
Structure for example can generally be influenced by the position of circuit board in the housing, by " the inner case of housing 102（Innenleben）" influence
