Description

Technical Field

[0001] The present invention relates to a connector housing assembly and a coaxial connector including the connector housing assembly. Background Technology

[0002] In existing technologies, the rear cover of a high-definition automotive camera is made of cold-forged aluminum alloy. The camera rear cover is integrally formed with the connector housing. Due to the high requirements for the snap-fit ​​features and dimensions of the connector housing, cold forging is difficult and requires secondary processing. In addition, when the snap-fit ​​features on the automotive connector housing are different, the mold needs to be redesigned and manufactured, which is very costly.

[0003] Furthermore, in existing technologies, a sealing ring is used to seal the outer terminals of the connector to the rear cover of the camera. The sealing ring typically needs to be at least 2mm thick, and its thickness increases further due to compression after assembly. Therefore, the sealing ring requires at least 3mm of space in the connector height. Currently, the development trend of automotive high-definition cameras is towards high pixel counts and small size. Therefore, the sealing ring, to some extent, limits its application. Summary of the Invention
