Corrugated Tube Connector With Tapered Braid Locking Under Pressure

The patent applies local quality by adding projections only at specific locations on the tapered surfaces where braid confinement is most critical. The projections are not distributed uniformly but are strategically placed to provide enhanced local gripping force on the braid, while the rest of the tapered surface maintains its original simple geometry for ease of manufacturing.

The projections act as intermediary elements between the tapered surfaces and the braid. They provide an additional mechanical interface that enhances the holding action without requiring complete redesign of the tapered surface geometry. The projections mediate the force transmission from the sleeves to the braid, improving reliability while maintaining overall structural simplicity.

The patent creates a localized narrow holding region through the projections that concentrates the gripping force on a specific annular strip of the braid. This narrow region provides firm holding under pressure, while the overall sleeve structure remains sufficiently large to accommodate easy braid installation. The transition from wide to narrow holding region is achieved through the gradual taper combined with the localized projection feature.

The patent transitions from a uniform wide holding region to a concentrated narrow holding region by introducing projections that create a new dimensional feature. The projections add a radial dimension to the holding mechanism, creating a narrow annular strip-like region where the braid is firmly confined. This dimensional change allows the holding force to be concentrated in a specific zone rather than distributed uniformly.

The patent applies preliminary anti-action by providing projections that pre-constrain the braid in the narrow holding region before high pressure is applied. These projections create a preliminary mechanical lock that prevents the braid from moving axially or radially. When high pressure is subsequently applied inside the tube, the braid remains securely held because the projections have already established a confining geometry that resists the pressure-induced forces.

The projections perform preliminary action by establishing the braid holding configuration during assembly, before the tube is subjected to operating pressures. The narrow annular region created by the projections pre-positions and secures the braid in place. This preliminary securing action ensures that when high tension and pressure are later applied to the tube, the braid is already firmly retained and cannot become dislodged.
