Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and in particular to a vehicle-mounted sealed connector and a camera module. Background Art

[0002] The vehicle camera module is installed inside or outside the car cabin to realize assisted driving functions such as ADAS, CMS, DMS, OMS, streaming media rearview mirror, etc. When it rains or snows, rain and snow will affect the camera's imaging, making the related assisted driving functions limited or unavailable. In order to improve the coverage of assisted driving scenarios, the camera needs to support heating function to achieve the purpose of defrosting, defogging, and snow removal.

[0003] In the prior art, there are three main ways to achieve the heating function of the camera: (1) A heating device is installed on the outside of the lens, and the heating device is powered by an external independent power supply wire to achieve heating of the lens; in this method, since the heating device is arranged on the outside of the lens, the heat needs to be transferred to the lens through the lens barrel during heating, which greatly reduces the heating efficiency and increases the power consumption. At the same time, the design of the external power supply wire reduces the integration and reliability of the camera module. (2) A complete set of independent heating mechanisms, the camera module is arranged inside the heating mechanism and images the external environment through the glass lens of the heating mechanism. The heating mechanism indirectly ensures the clarity of the camera module by heating its own glass lens; this method is costly, and the entire set of independent heating mechanisms is large in size, which is not conducive to the miniaturization of the camera, and the glass lens of the heating mechanism itself will reduce the clarity of the camera imaging. (3) The lens has a built-in heating ring and an FPC or wire extending outward, which is connected to a connector arranged on the camera circuit board assembly to achieve heating of the lens; however, existing automotive camera connectors are generally data transmission connectors with relatively simple functions, which only have data transmission functions. If heating and defogging are required, additional electrical connectors need to be added to achieve this, and the integration is low, resulting in a larger camera module size, which is not conducive to the miniaturization design of the camera module.
