Antenna device
View Patent ↗The present invention provides an antenna device that is easy to manufacture by doing away with the wiring section. The antenna device includes an antenna member housed inside a nearly tubular case and a terminal body electrically connected to the antenna member for taking out electrical signal to outside, and the antenna member is sealed inside the case. The antenna device also has a housing for sealing the antenna member inside the case for engaging with a connector to be coupled, and a plugging member having an O-ring and a terminal stage fit into a nearly integral unit.
1. An antenna device comprising:
a tubular case having an opening on one side face;
an antenna member housed inside the case;
a terminal body electrically connected with the antenna member and outwardly extending; and
a plugging member having the terminal body and sealing the antenna member inside the case and closing the opening of the case,
wherein the plugging member is integrally provided with a housing which is engaged with a connector to be coupled, and said plugging member is non-movable relative to said tubular case, and
the plugging member includes an O-ring which seals the inside of the case.
2. The antenna device of claim 1 , wherein the terminal body is integrally provided with
a plug formed by processing a thin metal sheet to a predetermined configuration, and to be connected with the connector to be coupled, and
an electrode to be electrically coupled with the antenna member.
3. The antenna device of claim 2 , wherein the plug of the terminal body is formed by folding a thin metal sheet to a predetermined thickness.
4. The antenna device of claim 1 , wherein said plugging member further includes a locking mechanism for securing said tubular case to said plugging member.
5. The antenna device of claim 1 , wherein the plugging member closes the opening of the case to prevent water from entering into the case.
6. The antenna device of claim 1 , wherein the O-ring seals the inside of the case to prevent water from entering into the case.
