In a specific embodiment, the distance between the center of the terminal connector and the center of the PCB board is 2.7mm, by virtue of the arrangement, the center of the terminal connector can be deviated from the center of the PCB board, and a certain gap can be reserved between the terminal connector and the screw post, so that the wire harness connector connected with the terminal connector can be normally inserted on the rear shell of the camera. In a specific embodiment, when the distance between the center of the terminal connector and the center of the PCB exceeds 3.7mm, the gap between the terminal connector and the screw post is too small, so that the problem that the wire harness connector interferes with the screw post on the rear shell to connect the terminal connector is solved, in addition, due to the requirement of the size of the edge of the laser welding process, the size required by laser welding is reserved between the screw post and the edge of the rear shell, and the terminal connector and the screw post are required to meet the related specified size, so that the gap between the terminal connector and the screw post is limited.
In a specific embodiment, the vehicle-mounted camera with smaller volume can be manufactured by the arrangement of the embodiment, and when the distance between the center of the terminal connector and the center of the PCB is set to be 2.7mm, the size of the camera can be 18mm in length, 18mm in width and 30.8mm in height, and compared with the current vehicle-mounted camera (the length and the width are generally more than 23mm, and the height is generally more than 33 m), the vehicle-mounted camera with smaller volume is remarkably reduced.
In summary, according to the processing method of the miniaturized vehicle-mounted camera and the miniaturized vehicle-mounted camera disclosed by the application, the terminal connectors are eccentrically arranged relative to the PCB, so that the space utilization rate of the PCB can be improved, and when larger components are arranged, the larger components can be arranged close to the middle of the PCB, so that the area of the PCB can be reduced, the volume of the whole vehicle-mounted camera can be reduced, the material cost is low, the occupied vehicle body space is small, and the arrangement and the installation of related components of the vehicle body are facilitated; the PCB and the shell are fixed by adopting adhesive, so that screws are not required to be used for fixing the PCB, and the whole volume of the camera is reduced; the lens and the shell are bonded by glue, so that threads are not required to be arranged on the lens to be connected with the shell, and the size of the camera is reduced; and the front shell and the rear shell are connected together in a laser welding mode, so that locking of the front shell and the rear shell is not needed by adopting screws, the size of the camera is further reduced, the utilization rate of the whole space structure of the camera is improved, the material cost is lower, the occupied vehicle body space is small, and the arrangement and the installation of the vehicle body are facilitated.
