Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an antenna attaching/detaching device used for attaching, for example, a dipole antenna to a cabinet such as a television receiver.

[Conventional technology]

Conventionally, as the above-mentioned antenna attachment/detachment device,
As shown in FIGS. 3 and 4, a pair of telescopic rod antennas 2 are supported in a box-shaped antenna holder 1 which is integrally molded from an elastic synthetic resin material so that they can be raised and rotated. A coaxial plug part 3 connected to the antenna 2 is made to protrude from one end surface, and a claw part 4 and a protrusion part 5 are made to protrude from the lower part of both sides of the holder 1 in a row in front and back, and are formed in the cabinet 6 of the television receiver. The holder 1 is fitted into the fitting groove 7 from the opening at one end thereof, and the claw portion 4 and the protruding portion 5 are engaged with the engagement groove 9 formed at the lower part of both side walls 8 of the fitting groove 7. There was one in which the claw part 4 was locked in a locking part 10 provided in the fitting groove 9, and the coaxial plug part 3 was fitted into a plug hole 12 provided in the end wall 11 of the fitting groove 7.

[Problem that the invention attempts to solve]

However, the conventional antenna attachment/detachment device described above utilizes the elasticity of the claw portion 4 to push the holder 1 horizontally and pull it out to perform attachment/detachment operations. It is difficult to create a mechanism that makes it easy for the holder 1 to be attached and removed, such as making it easy to slip out and removing it, and making it difficult to pull out, such as requiring a large force to push in. Therefore, there is a problem that the electrical connection by the coaxial plug section 3 becomes unstable. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide an antenna attachment/detachment device that allows an antenna holder to be easily attached and that makes it difficult for the holder to come off.

[Means to solve the problem]

In order to achieve the above object, the antenna attaching/detaching device of the present invention has levers arranged on the outside of both sides of an antenna holder made of an elastic material that supports a rod antenna, with a gap between these sides. A holder fitting recess formed in the cabinet, the lower end of which is integrally connected to the side surface, and a right triangular claw portion having an oblique side sloped forward in the insertion direction of the holder is formed on the outer surface of the lever. At the same time, the claws are engaged with engagement holes formed on both side walls of the recess, and the coaxial plug protruding from the bottom of the holder and connected to the antenna is inserted into the bottom wall of the recess. It is inserted into the plug hole so that it can be pulled out.

[Effect]

The antenna attachment/detachment device of the present invention is constructed as described above, and since the claw portion provided on the lever is in the shape of a right triangle with the oblique side sloped forward in the insertion direction, by pushing the holder from above, The holder can be easily fitted into the holder fitting recess of the cabinet, and by pressing the lever inward and elastically deforming it, the claw part will come out of the engagement hole, so in this state you can easily pull out the holder and remove the cabinet. The holder can be removed from the cabinet, making it easy to attach and detach the holder, and the claws engage with the engagement holes with great elasticity, preventing the holder from accidentally slipping out and coming off the cabinet. Since the holder is pulled out while pushing the lever inward when pulling out the holder, there is less wear on the claw part and the coaxial plug part does not rattle, making it easier to connect electrical equipment such as TV receivers with this coaxial plug part. is also stable.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 2. In FIGS. 1 and 2, reference numeral 13 designates an antenna holder integrally molded with a box-like elastic synthetic resin, and both sides 14 of this holder 13
A lever 15 is disposed on the outer periphery of the levers 15 and 15 parallel to each other with a gap therebetween to approximately the same height.
The outer surface of the middle part has a so-called forward oblique side 16a whose protrusion length increases toward the upper surface, and the upper side 1
A right triangular claw portion 16 with horizontal portion 6b is provided protrudingly, and a coaxial plug portion 1 is provided on the bottom surface 17 of the holder 13.
8 is provided protrudingly. A pair of telescopic rod antennas 2 are supported on the holder 13 so as to be tiltable and rotatable, and these rod antennas 2 are electrically connected to a coaxial plug portion 18. Note that the upper end portion 15a of the lever 15 is formed to protrude outward and to be thick. Further, reference numeral 19 designates a cabinet of a television receiver, and this cabinet 19 is formed with a holder fitting recess 20 that is open only on the top surface. There is a plug hole 24 in the bottom wall 23 of the
are formed respectively. The holder 13 is connected to the cabinet 1 from above.
9 and fit into the recess 20 without a gap, the claw part 16 of the lever 15 is engaged with the engagement hole 22, and the coaxial plug part 18 is further fitted into the plug hole 24 for installation. In this case, the claw portion 1 of the lever 15
As described above, the oblique side 16a of the lever 15 extends forward in the insertion direction, so that the lever 15 can be easily inserted with a small force.
is elastically deformed inward, reaches the engagement hole 22, and the lever 15 elastically returns, causing the claw portion 16 to move into the engagement hole 22.
2, the holder 13 can be easily mounted, and the claw portion 16 has a sufficient protrusion length to engage with the engagement hole 22. In addition, in the engaged state of the holder 13, the upper side 16b of the claw portion 16 is horizontal, so even if an upward pulling force is applied to the holder 13 when the rod antenna 2 is extended, the upper side 16b
is locked to the upper wall of the engagement hole 22, so that the holder 1
3 slips upward and never comes off. To remove the holder 13, press the upper end 15a of the lever 15 inward. This will cause the lever 15 to elastically deform and the claw 16 to disengage from the engagement hole 22. In this state, pull the holder 13 upward. ,
It can be easily removed from the cabinet 19 with little force. In addition, in this embodiment, the coaxial plug shaft 18 fitted into the plug hole 24 by attaching the holder 13 is as follows.
Electrical connection is established to the television receiver via a connector (not shown) inside the cabinet 19, and the electrical connection is interrupted when the holder 13 is pulled out.

[Effect of the idea]

As explained above, according to the present invention, only the lower end portion is connected to both side surfaces of the antenna holder, and the other portion has a lever with a gap between the side surfaces, and a lever is provided on the outside of these levers in the insertion direction. Since the right-angled triangular claw portion with the oblique side having a forward slope is provided, by pushing the holder down into the holder fitting recess of the cabinet, the claw portion can be inserted into the engagement hole provided in the side wall of the recess with a small force. The holder can be easily engaged, and the claw can be reliably engaged with the engagement hole, so even if a pulling force is applied to the holder, the holder will not come off easily. The connection with other devices is stable, and by pressing the lever inward to remove the claw from the engagement hole and pulling up the holder, it can be removed with a small amount of force, making it easy to attach and detach the holder. Both can be done easily and the wear of the claws can be reduced.
