Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0027] For portable devices, simple dedicated antennas need to be specially designed, and the transmission efficiency is not high; some portable devices need to use external wires such as power cords and earphone cables as antennas, such as FM transmitting antennas, which will cause interference and compare Large; some require a special external antenna, which adds additional cost. How the present invention solves the above problems is described below...

Abstract

The invention provides a power line, a signal transmitting device, and a head-up display. The power line comprises a coaxial cable including an inner conductor, an inner insulator, an outer conductor,and an outer insulator having a concentric relationship; a power interface pair including a first power interface connected to the inner conductor and a second power interface connected to the outerconductor, wherein the first power interface and the second power interface are configured to be connected to a power source device; and an antenna interface connected to the outer conductor. The power line solves the antenna interference and the additional cost, and achieves an effect of reducing antenna interference and saving antenna cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a power cord, a signal transmitting device and a head-up display. Background technique [0002] Many devices are equipped with antennas, such as FM antennas, most of which are receiving antennas, and there are also many transmitting antennas. There are various styles of FM transmitting antennas, such as antennas for fixed transmitting base stations, antennas for portable devices, fixed antennas, simple installation antennas, dedicated antennas, antennas borrowing other signal lines, etc. . [0003] For portable devices, simple dedicated antennas need to be specially designed, and the transmission efficiency is not high; some portable devices use external wires such as power cords and earphone cables as FM transmitting antennas, but the interference of such antennas will be relatively large; some Others use a dedicated external antenna, which adds additional cost. [0004] For example...
