Abstract

For a VHF dipole antenna formed with an antenna iron core and an external composite material housing protecting the antenna iron core by being inserted to inside, the present invention relates to a precise and improved durability type VHF dipole antenna comprising of a rubber housing lid which is formed as a cone type O-ring, is pressed into an forcibly expanded type entrance of the external composite material housing, from an end part of the antenna iron core to support a coaxial formation of the external composite material housing and the antenna iron core, and to support a combination of the antenna iron core with the external composite material housing, and maintains being airtight inside of an internal antenna of the external composite material housing, thereby preventing corrosion in the antenna iron core. After assembling of the dipole antenna, according to the present invention, provided is a precise and improved durability type VHF dipole antenna which prevents corrosion of the antenna iron core and damage, by external impacts, to the antenna iron core, by maintaining the same axis of antenna iron core and by forming inside airtightly.

Description

Precision inner spherical VHF dipole antenna [0002]

The present invention provides a VHF dipole antenna comprising an antenna core and an outer composite housing for inserting and protecting the antenna core, the VHF dipole antenna comprising a conical O-ring, A housing of a rubber material for supporting the coupling between the antenna core and the outer composite housing while supporting the coaxial formation of the outer composite housing and the antenna iron core while retaining airtightness inside the outer composite material to prevent corrosion of the antenna core; And a stopper. The present invention relates to a precision internal spherical VC dipole antenna.

Generally, a VHF dipole antenna is generally formed of an antenna core and an outer composite housing for inserting and protecting the antenna core.

The dipole antenna is an antenna that improves the distance by forming two polarities. Techniques such as the utility model application 20-1996-0060737 and the patent application 10-2007-0089439 are being developed.

The outer composite housing of the dipole antenna is assembled by inserting the antenna core at the end thereof. For the sake of this assembling process, the inside of the end portion is formed as a wedge-shaped entrance as shown in FIG.

However, since the internal airtightness is not maintained, corrosion of the antenna core is caused, and the external impact is directly applied to the antenna core Thereby causing damage to the antenna core.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a method of manufacturing a dipole antenna, in which the coaxial axis of the antenna core is maintained and the inner airtightness is formed after the dipole antenna is assembled to prevent corrosion of the antenna core, And an object of the present invention is to provide a precision internal spherical VC dipole antenna.

According to another aspect of the present invention, there is provided a VHF dipole antenna comprising an antenna core and an outer composite housing for inserting and protecting the antenna core, the VHF dipole antenna comprising a conical O- Shaped outer housing to support the coaxial formation of the outer composite housing and the antenna iron core while supporting the coupling between the antenna core and the outer composite housing while maintaining the airtightness of the antenna inside the outer composite material, And a housing stopper made of a rubber material for preventing a vibration of the housing. The present invention is directed to a precision internal spherical VC dipole antenna.

Hereinafter, the present invention will be described with reference to the drawings. In the following description of the present invention, a detailed description of related arts or configurations will be omitted when it is determined that the gist of the present invention may be unnecessarily obscured will be.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to be exemplary, self-explanatory, allowing for equivalent explanations of the present invention.

FIG. 1 is a cross-sectional view of a conventional dipole antenna, and FIGS. 2 and 3 are cross-sectional views of a dipole antenna according to the present invention.

As shown in the drawings, the present invention relates to a VHF dipole antenna, and is composed of an outer composite housing 10 having an enlarged-type inlet 100 formed at an end thereof, an antenna core 20 and a housing cap 30 do.

The VHF dipole antenna is generally formed as an outer composite housing 10 for inserting and protecting the antenna core 20 and the antenna core 20 as shown in FIG.

When the antenna core 20 is inserted at the end of the outer composite housing 10, the inside of the end of the outer composite housing 10 is formed as a wedge-shaped expansion type inlet 100 for assembly convenience.

In this case, since the antenna core 20 is prevented from being coaxial with the antenna core 20 and the inner air tightness is not maintained after the assembly, And the external impact is transferred to the antenna core 20 as it is, thereby causing the antenna core 20 to be damaged.

In order to prevent this, according to the present invention, a housing stopper 30 of a rubber material is press-fitted into the expansion-type inlet 100 formed at the end of the outer composite housing 10.

The shape of the housing stopper 30 may be a ring-shaped O-ring 30-1 as shown in FIG. 2, or a conical O-ring 30-1 corresponding to a wedge shape of the expansion type inlet 100 as shown in FIG. 2) so that airtightness is maintained during tightening.

According to the housing stopper 30, the coaxial axes of the outer composite housing 10 and the antenna core 20 are supported, and the coupling between the antenna core 20 and the outer composite housing 10 is supported, And the airtightness of the inside of the outer composite housing 10 can be maintained, thereby preventing the corrosion of the antenna core 20.

It will be apparent to those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that the technical spirit of the present invention is to the extent possible.
