Camera Module Connector Layout for Compact Imaging Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices, such as vehicle-mounted cameras, have a large size due to the arrangement of the camera and connector, which complicates design and installation.
Innovation Solution
The imaging device is designed with a connector housing overlapping a flange of the holder body, allowing the connector and flange to be aligned in a direction perpendicular to the optical axis, reducing the overall size by overlapping them without physical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera and connector are arranged adjacent to each other in the width-wise direction, then the communication line can extend from the connector, but the size of the imaging device body increases
Solution Approach 1:
The patent transitions from a two-dimensional side-by-side arrangement to a three-dimensional overlapping arrangement. The connector housing is positioned to overlap with the holder body when projected onto a plane perpendicular to the optical axis, utilizing the depth dimension (direction perpendicular to both optical axis and width-wise direction) to reduce the overall footprint in the width-wise direction while maintaining communication line accessibility
2Volume of moving object
If the connector housing and holder body are arranged to overlap, then the size in the width-wise direction is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent introduces a case as an intermediary component that receives both the holder body and connector housing. The case provides a standardized mounting interface and positioning structure, acting as a mediator that simplifies the alignment between the holder body and connector housing, thereby reducing the actual manufacturing precision requirements for their direct alignment

AI summary
An imaging device is provided which includes a camera module, a case, a cover, a board, a terminal, and a connector housing. The camera module includes a holder in which a lens is disposed and an image sensor which captures an image in response to light having passed through the lens and outputs it in the form of an electrical signal. The cover 45 defines an inner chamber along with the case in which the lens and, the holder 256, and the image sensor are disposed. The board obtains the electrical signal from the image sensor. The terminal connects with the board to achieve transmission of the electrical signal therebetween. The connector housing has the terminal disposed therein. The holder includes a holder body and a flange. The holder body has light, as having passed through the lens, travel therein. The holder body is arranged adjacent to the connector housing in a first direction. The flange extends in the first direction from a portion of the holder body which faces the connector housing. The flange is secured to the case. If the flange is projected onto a plane in a direction perpendicular both to a direction in which an optical axis of the lens extends and the first direction, the connector housing overlaps the flange. This structure enables the overall size of the imaging device to be reduced.
