1. Field of the Invention
This invention relates to a coaxial dipole antenna manufactured with coaxial cable and ground tube through pressing, wherein an upper end is pressed with a jacket and a metallic mesh of the coaxial cable for fixing the cable, grounding, and transmitting energy.
2. Description of the Prior Art
Recently, the combination between electronic devices or between cables is almost conventional welding connection, and the process of antenna also employs welding connection. However, those processes in electronics industry nowadays trend toward unleaded process. Therefore, the conventional structure and process not only cause air pollution, but also break the antenna structure resulted form defective welding or high temperature.
For solving the problems mentioned above, the industries in the field develop low-pollution welding materials as the connecting medium. Unfortunately, any welding materials always causes pollution and hard to maintain in follow-up service, and the yield of finished products will be reduced. Therefore, the cost of welding, check, and product management will increase.
The main objective of the present invention is to employ press assembly to connect devices. The press assembly can be automatically controlled to achieve product management. Furthermore, the present invention does not use the tin without Heavy metal, so the present invention does not cause environmental pollution and simultaneously conforms to environmental regulation.
In order to understand objectives, characteristics and advantages of the present invention, the present invention will be described with
An insulator 4 and a metallic conductor 3 can be added into the coaxial dipole antenna of the present invention. Another embodiment of the present invention are shown in
In such case, the base 41 and the cover 42 are tightly combined by using a high frequency wave. Alternatively, a predetermined amount of connecters (414, 422) are formed on the base 41 and the cover 42. The connecters (414, 422) can be cylinders and casing pipes, wherein an outside diameter of the cylinder is slightly larger than an aperture of the casing pipe to form tightening effect there between, and therefore a coaxial dipole antenna is formed.
Hence, the coaxial dipole antenna of the present invention is manufactured with coaxial cable and ground tube by press assembly, and complete elements thereof are assembled through pressing. The cable can be fixed, and the coaxial dipole antenna can ground and transmit energy. Because the elements of the coaxial dipole antenna are combined with each other by pressing, the coaxial dipole antenna can be manufactured by automation. Therefore, the product thereof can be increased, and the quality thereof can be controlled. Accordingly, the coaxial dipole antenna of the present invention overcomes the drawback of the conventional antenna.
Although specific embodiments have been illustrated and described, it will be obvious to those skilled in the art that various modifications may be made without departing from what is intended to be limited solely by the appended claims.
