Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an antenna mounting device in an electronic device such as a radio receiver.

2. Description of the Related Art Generally, an antenna mounting device for an electronic device such as a radio receiver has a structure in which an antenna 1 is adhesively fixed onto a printed wiring board (hereinafter referred to as a board) 3 by a double-sided tape 5 as shown in FIG. ing. The antenna 1 and the substrate 3 are electrically connected to each other by inserting the antenna lead wire 4 into a through hole provided in the substrate 3 and soldering 6 with a copper foil portion of the substrate 3. FIG. 8 shows the substrate 3 and the antenna 1 by the antenna lead wire 4.
Are temporarily connected, and finally the substrate is sandwiched and fixed by molding pillars or the like provided in the front and back cabinets.

The problem to be solved by the invention is that the antenna 1
Board 3 is needed under the
Also, the set thickness becomes thicker. Further, the adhesive reliability of the double-sided tape 5 is also low and the fixing becomes unstable. On the other hand, in the connection method using the antenna lead wire 4, many problems such as disconnection of the antenna lead wire 4 occurred during the work, and the structure had many problems in terms of quality.

The present invention solves such conventional problems, and an object of the present invention is to provide an antenna mounting device capable of holding an antenna with a simple structure.

Means for Solving Problems The antenna mounting device of the present invention is provided with a recess and a tongue for fitting the end face of the board and temporarily fixing the antenna mounting component to which the antenna is fixed, and the antenna mounting component is temporarily fixed. It is designed to be mounted by tightening screws together with the assembled board sandwiched by the front and back cabinets.

Effect The antenna mounting device of the present invention enables temporary fixing of the antenna mounting component and the substrate by the tongue provided on the antenna mounting component, and the antenna and the substrate can be assembled into the cabinet in an integrated state. It was done like
The electrical adjustment is possible in the state of the board, there is no disconnection of the antenna lead during the assembling work, and stable attachment of stable quality is possible, which has many advantages.

Embodiment Hereinafter, an antenna mounting device according to an embodiment of the present invention will be described with reference to the drawings. Figure 1, Figure 2, Figure 3, Figure 4, Figure 5
FIG. 6 and FIG. 6 show an embodiment of the present invention. FIG. 1 is a perspective view of the present invention, in which the antenna 1 is provided with a pair of left and right elastic tongues 8.
And the tongue piece 10 provided in the antenna mounting part 7 in a state of being integrated with the antenna mounting part 7.
It is temporarily fixed to the substrate 3 by 11. Reference numeral 2 denotes a bobbin wound around the antenna, which is electrically connected to the substrate 3 by soldering the antenna lead wires 4 at both ends of the bobbin. FIG. 1B shows a state in which the substrate 3 is inserted into the antenna mounting component 7 and temporarily fixed. 2 to 4 show a recess 9 and a tongue piece 10 provided in the antenna mounting component 7,
11 is a cross-sectional view of each of FIG. FIG. 2 is a sectional view of the recess 9. The substrate 3 is inserted into the concave portion 9 and has a structure that regulates the vertical direction and the inserting direction. FIG. 3 is a sectional view of the tongue piece 10. The board 3 is restricted in the upward direction by the tongue piece 10, and the convex portion 13 provided on the tongue piece 10 is fitted into the through hole 12 provided on the board to prevent the board 3 from falling off. FIG. 4 is a sectional view of the tongue piece 11. The tongue piece 11 has a structure that regulates the downward direction of the substrate 3. FIG. 5 is a sectional view showing a state in which the antenna mounting parts are fixed to the front and back cabinets to complete the antenna device. The antenna mounting component 7 is fixed together with the substrate 3 by a screw 19 by a molded pillar 17 provided in the front cabinet and a molded pillar 18 provided in the back cabinet 16 while being sandwiched. FIG. 6 is an enlarged cross-sectional view of a state where the antenna mounting component is fixed with screws. The screw tightening is performed at the tongue piece 10 provided on the antenna mounting component 7. The tongue piece 10 is provided with a through hole 14 through which the screw 19 passes, so that the screw 19 penetrates together with the through hole 12 provided in the substrate 3.

As described above, according to the present invention, the recess and the tongue provided on the antenna mounting component ensure the temporary fixing to the board, and the antenna is removed during the assembly work in the cabinet, and the antenna lead wire is not attached. Stable quality can be obtained without disconnection or misalignment. Furthermore, since the mounting position of the substrate is within the thickness of the antenna mounting component, it is possible to reduce the set thickness. Further, it has an excellent advantage that the substrate size can be reduced.
