Vehicle Connector Frontal Shield for Seal Alignment

The patent introduces a guiding structure as an intermediary element between the complementary casing and the annular seal. This guiding structure mediates the mating operation by constraining the complementary casing to move coaxially, preventing non-coaxial sliding that would cause axial deformation of the seal. The intermediary structure protects the soft seal from damage while maintaining its radial sealing capability.

The patent implements preliminary alignment action through the guiding structure before the complementary casing contacts the annular seal. The guiding structure establishes coaxial alignment in advance, ensuring that when the mating operation proceeds, the seal is subjected only to radial compression and not axial deformation. This preliminary action prevents the sock-folding deformation before it can occur.

The patent segments the mating operation into two independent functions: alignment/constraint function performed by the guiding structure, and sealing function performed by the annular seal. The guiding structure handles the alignment and prevents non-coaxial sliding, while the soft seal handles the radial sealing. This segmentation allows the casing to move freely in the axial direction while preventing harmful lateral movements.

The guiding structure acts as an intermediary constraint that does not completely restrict movement but rather guides it along the correct path. It maintains ease of operation by allowing axial movement while preventing non-coaxial sliding that would damage the seal. The intermediary structure enables controlled freedom of movement.
