Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, the antenna outlet structure that one preferred embodiment of the utility model provides, including upper cover 1, lower cover 2, line
Cable assembly 3, satellite antenna 4, pedestal 5 and support rod 6.Wherein, upper cover 1 is fixedly connected with lower cover 2.The connection jaws of cable-assembly 3
Place is equipped with antennal interface, and one end that cable-assembly 3 is equipped with antennal interface passes through satellite antenna 4 and upper cover 1, is fixed in upper cover 1；
The other end of cable-assembly 3 is then fixed on pedestal 5.In addition, the lower end surface of lower cover 2 is fixedly connected with support rod 6.Thus may be used
See, compared with prior art, the antenna outlet structure of the utility model, antennal interface setting exists in upper cover 1, the setting of support rod 6
Lower cover 2, so when in use, aerial signal will not be supported bar 6 and shelter from, so that received antenna signal effect is preferable.
Further, in this embodiment cable-assembly 3 is preferably realized by fixing seat 33 with being fixedly connected for pedestal 5.Its
In, fixing seat 33 is preferably rubber fixing seat, and cable-assembly 3 and rubber fixing seat are interference fitted.Compared to metal fixing seat
Speech, rubber fixing seat not only alleviate the overall weight of system, but also since rubber has certain elasticity, can to contact
Face cooperates even closer, so as to avoid the loosening of cable-assembly 3.
Further, at the antennal interface of upper cover 1 on be additionally provided with protection cap 7.When needing using instrument, protection is opened
Lid 7 connects external antenna and cable-assembly 3；When not needing using instrument, external antenna is removed, covers protection cap 7.Such as
This once, protection cap 7 can protect antennal interface and be not easy to be knocked, also prevent dust antennal interface deposit, to improve
The outdoor adaptability of antenna outlet structure.Protection cap 7 is preferably the double-colored part protection cap of highstrenghtpiston's alloy in the present embodiment.
Further, in this embodiment antennal interface is preferably SMA antennal interface 31.With existing antenna outlet structure
Antennal interface is compared, and 31 dimensions of SMA antennal interface is smaller, so that the overall volume of antenna outlet structure becomes smaller, into
And make the instrument easy to carry, improve the outdoor adaptability of the instrument.
Further, upper cover 1 is equipped with polygon location hole, the polygon positioning column on SMA antennal interface 31 with it is polygon
Shape location hole interference fit.The part that SMA antennal interface 31 stretches out upper cover 1 is equipped with fixing piece.The fixing piece is suitable for SMA antenna
Interface 31 is fixed in upper cover 1.Wherein, fixing piece is preferably locking nut 32.The design is closer by SMA antennal interface
31 are fixed in upper cover 1, in order to avoid using time length or hit and loosened.Locking nut 32 in the present embodiment is excellent
