Description

Vehicle-mounted camera rear shell connector Technical Field The utility model belongs to the technical field of electric connectors, and particularly relates to a rear shell connector of a vehicle-mounted camera. Background At present, most automobiles are provided with vehicle-mounted cameras, and the vehicle-mounted cameras are image acquisition equipment which is arranged on the automobiles and is used for monitoring surrounding environments and have the advantages of being convenient for reversing, recording driving, observing the internal and external environments of the automobiles in real time and the like. The vehicle-mounted camera generally comprises a front shell, a lens and a circuit board which are arranged in the front shell, and a rear shell connector which is matched with the front shell, wherein one end of the rear shell connector is connected with a matched end on the circuit board to realize guide connection, and the other end of the rear shell connector is in butt joint with an external vehicle-mounted wire harness to realize electric connection, so that data collected by the vehicle-mounted camera are received or the vehicle-mounted camera is controlled. But the Fakra head and the backshell of the existing vehicle-mounted camera are integrated, and are formed by forging and pressing aluminum alloy materials, so that the Fakra head is complex in structure, the structure of a forging and pressing die is complex, the service life of the die is low, CNC processing is required to be performed on the characteristics such as holes after forging and pressing is finished, the process flow is complex, the production period is long, and the production cost is high.
