Vehicle-mounted loop antenna apparatus and manufacturing method thereof

Abstract

The invention provides a vehicle-mounted loop antenna apparatus and a manufacturing method thereof. The apparatus comprises an antenna oscillator, an antenna base and a high frequency connector, wherein the antenna oscillator and the high frequency connector are installed on the antenna base; the antenna oscillator comprises a metal ring, a short welding foot and a long welding foot; the high frequency connector comprises a high frequency connector socket welding needle, a high frequency connector flange plate and the like; and the short welding foot of the antenna oscillator and the high frequency connector socket welding needle are overlapped, are wound firmly through a bare copper wire and then are welded. The vehicle-mounted loop antenna apparatus is characterized by further comprising a plurality of welding sheets. One end of each welding sheet is fixed to the high frequency connector flange plate; the non-fixed end of each welding sheet is bent by an angle of 90 degrees towards the direction of the antenna oscillator; the distances between the bending parts of the welding sheets are the diameter of a antenna oscillator material; and the long welding foot of the antenna oscillator is inserted to the vertically bent butt joint position of the rail ends of the welding sheets and is firmly connected with the high frequency connector flange plate in a welding mode. The apparatus and the method provided by the invention solve the problems of easy unsoldering, antenna swinging and the like caused by unfavorable environments of vibration and impact of an external environment and the like during a use process of a conventional vehicle-mounted antenna.

Description

technical field [0001] The invention relates to a vehicle-mounted loop antenna device and a manufacturing method thereof, belonging to the field of mechanical design. Background technique [0002] Chinese patent application CN200710027300.9 discloses a welding connection method for a line connector with double rows of connecting pins, which is completed by precise alignment lapping, welding and trimming between the soldering ends of the two rows of core wires and the corresponding soldering pins of the plug Accurate alignment and overlap of the solder pins realizes the welding connection between the solder pins of the plug and the solder ends of the core wires. However, in this welding connection method, the soldering pins of the antenna and the socket soldering pins of the high-frequency connector are overlapped and then soldered directly, and false soldering and desoldering are prone to occur in unfavorable environments such as vibration and impact. [0003] Most of the e...
