Plastic Housing for Electronic Connectors

Designed for signal transmission interfaces in automotive electronics, home appliance control boards, and industrial equipment, this black rectangular housing serves as the external protective shell and positioning skeleton for connectors. It features clips or mounting ears at both ends for secure PCB welding and fixation. The internal cavity is engineered with precise pin限位 slots and reinforcing ribs to ensure positional stability of metal terminals after insertion, providing sufficient mechanical strength to resist stress deformation during mating cycles.

Manufactured via single-shot injection molding using engineering plastics, the core processing focus lies in controlling the straightness of the elongated structure and the symmetry of side mounting holes to prevent assembly interference caused by uneven shrinkage. For the dense internal limiting features, high-quality mold cavity polishing and appropriate draft angles are essential to avoid cosmetic defects such as sink marks, flash, or stress whitening, ensuring smooth terminal mating and reliable insulation performance.

Supported by ISO 9001 and IATF 16949 quality management systems, our factory offers end-to-end services from mold design and precision injection molding to final assembly. For these non-standard connector housings, we strictly control key dimensional tolerances and appearance standards, utilizing Hexagon CMMs to verify hole spacing and profiles. Quotations and lead times are evaluated based on specific plastic material grades (e.g., PA66, PBT, LCP), flame retardancy requirements, mold cavity count, and order volume. We support custom manufacturing based on customer drawings and offer flexible supply modes for multi-variety, small-batch orders.
