Description

Vehicle-mounted amplifier and connecting structure thereof Technical Field The utility model relates to wireless communication of automotive electronics, in particular to a vehicle-mounted amplifier and a connecting structure thereof. Background At present, a plurality of vehicle-mounted electronic devices, such as a radio receiver, a touch screen display, a navigation device, a portable telephone and the like, are arranged in a vehicle, and are connected to an automobile antenna through a cable, and the automobile antenna can receive signals from the outside and send the signals to the vehicle-mounted electronic devices, but because the distance between the automobile antenna and the vehicle-mounted electronic devices is far, the problem of signal loss occurs, and therefore, different signal amplifiers are usually required to be arranged to relieve the problem of signal loss. The amplifier is generally installed on the interior panel beating of back door sheet metal component, because the back door is formed by two-layer panel beating (inner panel and planking) welding at least, when the back door sheet metal component is during the preparation, need first weld projection nut or draw the riveting nut on interior panel beating, then with interior panel beating again with outer panel beating spot welding together, the amplifier utilizes nut fixed mounting ground connection when finally loading. Because the amplifier needs to be grounded with the car body, the amplifier is fixed by adopting a mode of tightening a bolt and a projection welding nut or a rivet pulling nut on the car body, as shown in fig. 1a, 1b, 2a and 2b, the process requirement of the car body is improved, a welding process or a rivet pulling process is required to be added, and the welding or rivet pulling process can lead to the metal plate at the installation position to be welded and deformed by heat, or the biting force of the nut and the metal plate after rivet pulling does not meet the requirement.
