Description

[Detailed Description of the Invention] The present invention relates to a radiator with a built-in mixer for an outdoor antenna, particularly a VHF antenna.

The feature of the present invention is that a printed circuit board having a structure for connecting input and output power lines and equipped with circuit components constituting the mixer is connected to a pair of long ribs provided on both sides of the container body. It is inserted perpendicularly into the long groove to improve manufacturing work.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a container body made of synthetic resin, and U-shaped radiating elements 3,
3' and fix it inside the container body 1 with screws 4. At this time, at the same time, the U-shaped radiating element 3,
Connecting elements 5, 5' electrically connected to 3' are fixed to the container body 1 with screws 4. Note that a circuit component is connected between one of the connection terminals 5 and 5'.

Next, the printed circuit board 6 will be explained. As shown in detail in FIGS. 2 and 5, the printed circuit board 6 has connection terminals 7 and 7 for connecting an input-side feeder line (not shown) drawn out from a UHF antenna (not shown). Fixing screw 8 and Fig. 2,
As shown in detail in FIG. 4, there is a connection terminal 9 for connecting an output power supply line (not shown) connected to a television receiver (not shown), a fixing screw 8', and a guide for the power supply line. Guide 10 and input/
Screws 12, clampers 13, and springs 14 for fixing the output-side power supply lines themselves are installed on one side, and circuit parts constituting the mixer (not shown) are installed on the back side of this printed circuit board 6. There is.

Here, install the screw for connecting the output side feeder line.
8', 3 sets of connection terminals 9 are installed so that they can be used with either coaxial cables or parallel feeders.
When using a coaxial cable, use the screw and connecting terminal in the center; when using a feeder, use the screws and connecting terminals on both sides.

Further, 15 and 16 are holes for drawing out the output side power supply line and the input side power supply line to the outside of the container body 1, respectively.

As a result, the signal from the UHF antenna enters the mixer via the input feed line, and the signal from the VHF antenna,
That is, the signal is mixed with the signal entering from the U-shaped radiating elements 3, 3' in a mixer, and sent to the television receiver from the output side feeder line.

Screws, connection terminals, clampers, and UHF for connecting the input and output side feed lines as shown above.
A printed circuit board 6 equipped with a mixer that mixes and outputs the signal from the antenna and the signals from the radiating elements 3 and 3' is located at the tips of a pair of long ribs 17 and 17' integrally provided on both sides of the container body 1. Long groove 18 with closed
Both ends of the printed circuit board 6 are inserted and fixed into the holes 18'. At this time, as shown in FIG.
17' are pushed apart in the directions of arrows a and a', and the printed circuit board 6 is inserted into the long grooves 18 and 18'. After inserting the printed circuit board 6, the long ribs 17 of the container body 1,
Since 17' is a molded product, it returns to its original position due to its elasticity and securely holds the printed circuit board 6.

Note that the printed circuit board 6 fixed to the container body 1 in this way is referred to as the U-shaped radiating elements 3, 3'.
They are electrically connected to each other via screws 4, connection terminals 5, and lead wires 19. Moreover, what is indicated by a two-dot chain line in FIG. 2 is the lid body 20.

As explained above, according to the present invention, a structure for connecting input and output power supply lines is formed on a single printed circuit board, circuit components constituting a mixer are installed, and this printed circuit board is connected to a container. By utilizing the elasticity of a pair of long ribs integrally provided on both sides of the case body of the antenna radiator, which is the main body, the tips of the long ribs are inserted and fixed into the closed long groove.
The printed circuit board can be firmly fixed to the case body, and since the long rib is integrated into the case body, you can use metal fittings or the like to prevent the printed circuit board from coming off.
There is no need to fix it with an insertion tool or screws, etc.
This not only greatly improves work efficiency, but also has significant cost advantages.
