[0002]

2. Description of the Related Art As this kind of antenna mounting structure, a structure as shown in FIGS. 6 and 7 is known.
Here, the metal fitting 1 formed at the base end of the antenna body 11
2, a mounting hole 13 is formed from the side, and the base end of the antenna is inserted into the antenna mounting hole 16 of the device housing 15, and the antenna 12 is inserted into the metal fitting 12 at a position protruding into the housing 15. A terminal piece as a power supply fitting 18 is overlapped, and a fixing hole 19 formed in the terminal piece is aligned with the mounting hole 13. In this state, a male screw 14 is inserted into these holes 13 and 19, and these are tightened together. To this end, the distal end of the male screw 14 is screwed into a screw hole formed in a boss 17 provided on the housing 15 side.

[0003]

However, in such a mounting structure, the terminal piece is overlapped with the metal fitting 12 and
While maintaining the condition where 3, 19 are matched, the male screw 14
Is screwed into the screw hole of the boss 17, so that the assembling operation is difficult, and the screwing operation requires time and troublesome operation. In addition, in this antenna fixing structure, since the base end of the antenna 11 does not have a function of pulling it toward the housing 15, the looseness of the male screw 14 may cause the looseness of the mounting hole 13 within the range of clearance. May occur.

The present invention has been made based on the above circumstances, and has as its object to assemble an antenna having a configuration in which the assembling operation is simple, time and troublesome operations are not required, and no rattling occurs after assembling. It seeks to provide structure.

[0005]

Therefore, in the present invention,
The device housing, through the antenna mounting hole, insert the proximal end of the antenna main body, and fixing the antenna main body to the apparatus housing at its insertion end, the proximal end of the antenna main body insertion direction Is formed on an inner wall of the device housing, and a locking portion facing the locking portion is formed on an inner wall of the device housing, and a base end of the antenna body is An antenna mounting structure including a fixture having a wedge-shaped tip inserted into the antenna mounting hole from the inside of the device housing while being inserted into the antenna mounting hole.
The fixture has a wedge-shaped tip attached to the antenna.
In the state inserted in the mounting hole, the engaging portion and
A window portion facing the gap between the locking portions is formed, and the window portion
Through which a terminal strip for antenna feeding is inserted
There is a feature.

In this case, as an embodiment of the present invention, it is preferable that the terminal piece is a spring member elastically sandwiched between the engaging portion and the engaging portion.

Further, the spring member may be constituted by a leaf spring having a substantially V-shape or a U-shape, and the fixing member may have a U-shape straddling a base end and a locking portion of the antenna body. It is preferable to have a structure in which the window portion is formed on the side wall surface of the holder 4.

[0008] With such an antenna mounting structure, there is no danger of rattling occurring at the location where the housing and the antenna are assembled after assembly, and the assembly workability can be improved.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to FIGS. In the antenna mounting structure shown here, the base end of the antenna main body 1 is inserted into the equipment housing 8 via the antenna mounting hole (fixing hole) 9, and the insertion end portion inserts the antenna main body 1 into the equipment housing 8. In particular, in the present invention, an engagement portion that intersects with the insertion direction is formed at the base end of the antenna main body 1 in a shape bent in an L shape, and a rectangular locking member facing the insertion portion is formed. A portion (vertical wall) 10 is formed on the inner wall of the device housing 8 at a side of the antenna mounting hole 9, and the base of the antenna main body 1 is inserted into the antenna mounting hole 9. Wedge-shaped tip (projection) inserted into antenna mounting hole 9 from inside of 8
5 is provided.

In the fixture, the wedge-shaped tip 5 is inserted into the antenna mounting hole 9, and a window (engaging hole) 6 is provided beside the fixing member so as to face the gap between the engaging portion and the engaging portion 10. Are formed, and a terminal piece (feeding metal fitting) 7 for feeding the antenna is inserted through the window 6. In addition, an escape recess 3 for receiving the wedge-shaped tip 5 is formed at the base end of the antenna main body 1.

Further, the terminal piece 7 includes the engaging portion and the locking portion 1.
0, the spring member is elastically sandwiched between the spring member and the spring member. In particular, in this embodiment, the spring member is substantially V-shaped or U-shaped with claw portions formed at both ends to be engaged with the edge of the window portion 6. It is composed of a leaf spring having a letter shape. The fixture has a U-shaped holder 4 that straddles the base end of the antenna main body 1 and the locking portion 10, and has a structure in which the window 6 is formed on a side wall surface thereof.

In such an antenna mounting structure, the wedge-shaped tip 5 is strongly inserted into the antenna mounting hole 9 to fix the antenna body 1 to the housing 8 by a wedge effect. There is no danger of rattling occurring at the assembly point. In addition, there is no trouble of hole alignment or screwing operation at the time of assembling, and the assembling workability can be improved.

In particular, in this embodiment, the terminal piece 7 is inserted into the gap between the engaging portion and the locking portion 10 through the window portion 6 by a simple operation. Since it has a function of preventing the antenna body 1 from being pulled out toward the housing 8 due to its elasticity, the wedge does not loosen after assembly and there is no backlash.

The shape of the terminal piece 7 is not limited to the above-described one, but may be applied to a coil spring or a torsion spring having elasticity for returning elasticity.

[0015]

According to the present invention, as described in detail above, the base end of the antenna main body is inserted into the equipment housing via the antenna mounting hole, and the antenna is inserted into the equipment housing at the inserted end. and securing the unit, said the proximal end of the antenna body engagement portion that intersects the insertion direction are formed, also, the locking portion facing the which is located in the antenna mounting hole side, the equipment cabinet A fixture formed on the inner wall of the body and having a wedge-shaped tip inserted into the antenna mounting hole from the inside of the device housing with the base end of the antenna body inserted into the antenna mounting hole. Antenna mounting structure
In addition, the wedge-shaped tip of the fixture is attached to the antenna mount.
In the state inserted into the hole, the engaging portion and the
A window portion facing the gap of the stop portion is formed, and the window portion is
