Description
Technical field
This utility model relates to a kind of tuner, particularly a kind of installation and consolidates, and can effectively prevent signal disturbing
Tuner.
Background technology
Tuner is that television set is for receiving high-frequency signal and demodulating a kind of device of video information, currently used height
Frequently head is generally divided into digital signal tuner (digit tuner) and analogue signal tuner (simulation tuner).The work of tuner
With exactly faint video signal being amplified, and to transmission instability caused by anamorphose and interference at
Reason.Video frequency processing chip determines the resolution of image, and tuner then determines the stability of image.
The tuner used on the market at present, also exists waveguide pipe and fixes unsteady shortcoming, and tuner is anti-
Stop signal interference performance is poor, and signal stabilization is poor, and these shortcomings all cause inconvenience to use.
Utility model content
This utility model is i.e. for the problems referred to above present in current tuner, it is provided that a kind of install fixing firm,
And can effectively prevent signal disturbing, it is thus achieved that the tuner of stabilization signal.
Specifically, anti-interference tuner described in the utility model, including waveguide pipe and the circuit that is connected with waveguide pipe
Plate box, the top of waveguide pipe is guided wave mouth, is provided with circuit board in circuit board box, and circuit board box is provided with interface, outside waveguide pipe
Wall is provided with groove, for being fixed tuner.
Further, the inwall of described circuit board box is provided with 2-4 the baffle plate protruded, and its objective is that anti-stop signal is done
Disturb, and the good airproof performance when capping.
Further, described circuit board box has pin hole, between pin hole mesopore and hole, form filter capacitor,
Interference signal in circuit board box is filtered by filter capacitor.
Further, the interface on described circuit board box is waterproof port and waterproof port is provided with sealing ring counterbore.
Anti-interference tuner described in the utility model, has the advantage that
1, on the outer wall of waveguide pipe, it is provided with groove, may be used for connecting and fixing with external connection mechanism, contribute to
Stablize tuner；
2, the inwall at circuit board box is provided with 2-4 the baffle plate protruded, and during lidstock, tightness is good, can effectively prevent
Only external signal interferes with the signal in circuit board box；
3, in circuit board box, it is provided with pin hole, forms filter capacitor between pin hole mesopore and hole, in circuit board box
Interference signal filtered by filter capacitor, thus improve the capacity of resisting disturbance of tuner；
4, the interface on circuit board box is set to waterproof port, and waterproof port is provided with sealing ring counterbore, and tape splicing has outside
The better tightness when water joint of sealing ring and waterproof port are fixed sealing, thus avoid the rainwater gap from connector
In be flowed in interface.
Accompanying drawing explanation
Fig. 1 is the perspective view of this utility model embodiment；
Fig. 2 is the side view of this utility model embodiment；
Wherein, 1 be guided wave mouth, 2 for waveguide pipe, 3 for circuit board box, 4 for interface, 20 for groove, 30 for baffle plate, 31 for edge
Pin hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme described in the utility model is illustrated, it is therefore an objective to for
The public is more fully understood that described technical scheme rather than arbitrarily limits it.
As illustrated in fig. 1 and 2, anti-interference tuner described in the utility model, it is connected including waveguide pipe 2 with waveguide pipe 2
Circuit board box 3, the top of waveguide pipe 2 is guided wave mouth 1, is provided with circuit board in circuit board box 3, and circuit board box 3 is provided with and connects
Mouth 4, waveguide pipe 2 outer wall is provided with groove 20, and for being fixed tuner, it is individual convex that the outer wall of circuit board box 3 is provided with 2-4
The baffle plate 30 gone out, its objective is to prevent signal disturbing, and the good airproof performance when capping, and described circuit board box 3 is provided with edge
Pin hole 31, the interface on described circuit board box is waterproof port.
Anti-interference tuner described in the utility model, is provided with groove on the outer wall of waveguide pipe, may be used for outside
Bindiny mechanism connects and fixes, and contributes to stable tuner；In circuit board box, be provided with pin hole, pin hole mesopore and hole it
Between formed filter capacitor, the interference signal in circuit board box is filtered by filter capacitor, thus improves the anti-interference of tuner
Ability；On the inwall of circuit board box, additionally it is provided with 2-4 the baffle plate protruded, the lid when circuit board box body carries out lidstock
A part be connected with baffle plate so that circuit board box lid and circuit board box better tightness, thus in avoiding circuit board box body
The signal of signal and outside mutually disturb；Additionally the interface on circuit board box is set to waterproof port, on waterproof port
It is provided with sealing ring counterbore, better tightness when tape splicing has the water joint of sealing ring to be fixed sealing with waterproof port outside,
Thus avoid rainwater to be flowed in interface from the gap of connector.
It should be understood that foregoing includes that accompanying drawing is not the restriction to described technical scheme, it is true that identical or
Under the principle of approximation, the improvement that described technical scheme is carried out, including the shape of each several part, size, material used and identical
The equivalent of Functional Unit device, all within the technical scheme required by this utility model.
