DESCRIPTION OF THE PREFERRED EMBODIMENTS An antenna mounting apparatus for a portable telephone according to the present invention has an antenna 4 slidably inserted therein as shown in a side view of FIG. 1A and a longitudinal sectional view of FIG. Antenna holding member 1 to be held, and antenna holding member 1
Is fixed to a telephone case, and a locking member 3 that locks the antenna holding member 1 and the fixing member 2 is composed of three parts.

The antenna holding member 1 has a hole 12 through which the antenna 4 is inserted and into which a large-diameter engaging portion 41 provided at the base of the antenna 4 and a large-diameter engaging portion 42 provided near the tip end are fitted.
A cylindrical body 11 having a, and a flange 13 formed at the tip of the body 11, and provided with a groove 14 for rotation on the surface,
And four claw pieces 15 protruding in four directions perpendicular to the periphery of the rear end of the body 11.

The fixing member 2 has a hole 21 for inserting the antenna holding member 1 in which the locking member 3 is fitted in the body 11, and a flange 22 protruding inside one end. As shown in the figure, two wide first notches 23 are formed in the flange 22 in opposite directions, and two narrow first notches 23 are formed in a direction orthogonal to the first notch 23. A notch 24 is formed.

As shown in a developed view of FIG. 3, the locking member 3 has three cut-up pieces 32 and 33 and three notches for preventing rotation.
A thin elastic plate 31 formed with a notch 35 at the corner and a notch 35 at the corner is rounded into a cylindrical shape.
33 are cut and raised in directions opposite to each other, and the butted portion of the rounded elastic plate 31 is, as shown in the bottom view of FIG.
A slit 36 is formed.

As shown in FIG. 6, the antenna 4 is a linear body 40 having a core covered with a large-diameter engaging portion 41 of a conductor electrically connected to the core at the lower end. It is fixed by caulking, a screw 44 is cut at the upper end of the linear body 40, a large diameter engaging portion 42 is screwed into the screw 44, and a knob 43 is further screwed on a screw 45 of the engaging portion 42. Assembled by screwing. A flange 46 is formed at the end of the large diameter engaging portion 41 to prevent the antenna from coming out of the hole 12 of the antenna holding member 1.

Next, a procedure for assembling the antenna mounting device thus constructed in a portable telephone will be described.

After inserting the antenna 4 having a large diameter engaging portion 41 caulked and fixed at the lower end portion in advance into the hole 12 of the antenna holding member 1, the engaging portion 42 is screwed into the upper end portion, and further, the hand is pinched by hand. Then, a knob 43 to be pulled out is screwed, and the antenna 4 is slidably incorporated in the antenna holding member 1.

Next, the locking member 3 is fitted from the rear end of the trunk 11 of the antenna holding member 1 in which the antenna 4 is incorporated.
Four claw pieces 15 protrude from the rear end of the body 11, but since the locking member 3 is formed by rolling the elastic plate 31, the slit 36 is formed.
Can be easily fitted. Then, in the fitted state, the 4
The two claw pieces 15 are provided with the notch 34 and the slit 36 of the locking member 3.
, Respectively, to prevent the rotation of the antenna holding member 1 and the locking member 3.

The antenna holding member 1 into which the locking member 3 is fitted is inserted into the mounting hole 51 of the telephone case 5, and the cut-and-raised piece 33 of the locking member 3 is inserted into the wide cutout 23 of the fixing member 2. The fixing member 2 is fitted from the back side of the case while being aligned with either one.

At this time, the four claw pieces 15 of the antenna holding member 1 are provided with four notches provided on the flange 22 of the fixing member 2.
23 and 24, and further, the two raised pieces 32 of the locking member 3
Is fitted while being deformed inward by the flange 22 of the fixing member 2, and after passing through the flange 22, expands outward and locks inside the flange 22, as shown in the vertical sectional view of FIG. , The locking member 3 is the antenna holding member 1
And the fixing member 2 are connected.

When the assembled antenna mounting device is disassembled for repair or the like, when the groove 14 of the flange 13 of the antenna holding member 1 is turned 90 degrees by a tool, the two raised and 32 rotates to the wide notch 23 of the fixing member 2, so that when the antenna holding member 1 is pulled out, the cut-and-raised piece 33 of the locking member 3 is easily deformed inward by the flange 22 of the fixing member 2 and easily. Can be pulled out.

(Other Embodiments) In the antenna mounting apparatus of the embodiment described above, the antenna holding member 1 into which the locking member 3 is fitted is inserted into the mounting hole 51 of the telephone case 5. Although fixed, the backlash may occur in the thrust direction and the radial direction based on the dimensional variation of the parts used.

Therefore, in order to prevent such rattling, a taper 52 is formed on the inner wall of a mounting hole formed in the telephone case 5 as shown in a vertical sectional view of FIG. And
After the locking member 3 is fitted into the antenna holding member 1, the elastic O-ring 6 is expanded and fitted on the locking member 3.

After the O-ring 6 has been fitted into the locking member 3 in advance, the antenna holding member 1 is
Into the mounting hole 51 of the fixing member 3 while aligning the cut-and-raised piece 33 of the locking member 3 with one of the wide notches 23 of the fixing member 2.
Fixing member 2 from the back side of the case against the elasticity of O-ring 6
Insert and assemble.

When assembled, the O-ring 6 is attached to the mounting hole 52
Is elastically deformed in a space surrounded by the taper 52 of the inner wall of the inner wall, the locking member 3 fitted in the antenna holding member 1, and the flange 13, and absorbs the backlash between the antenna holding member 1 and the mounting hole 51. And can be fixed firmly.
