Abstract
The invention provides a high-frequency low-loss high-strength vehicle-mounted antenna whip body and base interface, which comprises a male plug and a female socket, wherein the male plug comprises a first cable, a socket, a first ferrule, a first lining, a first insulating lining and a contact pin; and the female socket comprises a second cable, a screw sleeve, a second ferrule, a second lining, a second insulating lining, a third insulating lining, a circular ring, a pin, a jack and a pressure spring. According to the invention, a plug-in structure is abandoned, an inner conductor and outer conductor crimping mode is adopted, in order to reliably connect the inner conductor and the outer conductor at the same time, an inner conductor inner compression spring is introduced, the outer conductor is in rigid contact after screwing, the inner conductor is in elastic contact, and the interface has the structural strength of an existing shaping product, high reliability and long service life; and the compression spring is designed in the inner conductor, and the parameter related to impedance is the outer diameter of the inner conductor, so that the compression condition of the compression spring does not influence the impedance characteristic of the interface, low-loss coaxial connection is realized at a high frequency band, and the interface problem of the broadband vehicle-mounted antenna is practically solved.
Description
technical field [0001] The invention relates to the technical field of vehicle-mounted antennas, in particular to a high-frequency, low-loss, high-strength vehicle-mounted antenna whip and base interface and an assembly method thereof. Background technique [0002] The vehicle-mounted antenna is used in a harsh environment, which requires the whip body to be disassembled repeatedly, the interface between the whip body and the base to have a long service life, and the whip body and the base to be connected reliably under harsh conditions such as vibration or impact. In recent years, due to the development of broadband technology, the demand for vehicle antennas has increased to cover high-frequency bands above 1000MHz. [0003] In the high-strength interface between the low-frequency band vehicle-mounted antenna whip body and the base of the current stereotyped product, in order to ensure the strength, when the outer conductor is screwed, the inner conductor rotates together ...
