Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector housing, a connector housing assembly and a connector thereof. Background Technology

[0002] In the field of connector technology, the connector housing, as a core component that protects the internal terminals and ensures connection reliability, undergoes continuous optimization in its structural design and molding process. Currently, most mainstream connector housings are manufactured using injection molding. Depending on functional requirements and assembly scenarios, the housing and internal support structures (such as frames and cores for positioning terminals) are often designed as a single unit or separate units.

[0003] However, significant limitations remain. While the integrated design simplifies assembly, combining the base shell and plastic frame into a single component results in insufficient structural flexibility, making it difficult to adapt to different module core sizes and limiting versatility. On the other hand, while the split design improves adaptability by separating the base shell and plastic frame, it faces critical structural molding challenges. For example, the grooves on the side of the base shell for fixing require a mold-mounted ejector mechanism, increasing mold processing costs and complexity, and potentially affecting structural dimensional stability due to issues with the accuracy of the ejector's movement. Furthermore, if the elastic cantilever beam fasteners of the plastic frame are integrated, assembling or disassembling individual module cores can easily cause other normal module cores to detach from their fixed positions, reducing the reliability of the connector.
