Pliable Deutsch Connector Boot for Reusable Moisture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deutsch connectors' shrink-wrap boots are often damaged during field servicing, requiring removal and reinstallation, which is inconvenient due to the need for heating equipment and resulting in a loose fit upon reassembly.
Innovation Solution
A pliable boot designed for Deutsch connectors, made of rubber or similar materials, that can be easily pushed onto and removed without heating, featuring a cylindrical portion for electrical wires and an adapter portion with a lip to engage with the shrink boot adapter, providing a moisture-resistant seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shrink-wrap boot is used on the Deutsch connector, then the connector is protected from moisture and environmental damage, but the boot must be removed and damaged during field servicing, requiring heating equipment and resulting in a loose fit upon reassembly
Solution Approach 1:
The boot is divided into distinct functional segments: a cylindrical portion for wire routing, a transition portion with increasing interior shape, and an adapter portion with engagement features. This segmentation allows the boot to be easily removed and reinstalled during field servicing while maintaining moisture protection, as each segment can flex and move independently during installation and removal operations.
2Strength
If a shrink-wrap boot is heated onto the adapter, then the boot provides a secure fit, but specialized heating equipment is required for installation and reinstallation
Solution Approach 1:
The patent replaces the thermal shrinking process with a mechanical expansion and contraction system. The transition portion's increasing interior shape allows the boot to expand during installation to accommodate the adapter, then contract to provide a secure mechanical interference fit. This eliminates the need for heating equipment while maintaining fit security through geometric design rather than thermal processing.
3Ease of repair
If the shrink-wrap boot is removed from the adapter during field servicing, then the connector can be serviced, but the boot becomes damaged and must be cut free or reinstalled loosely
Solution Approach 1:
The boot is designed with dynamic geometric features that accommodate repeated installation and removal cycles. The transition portion's progressive expansion and the adapter portion's engagement features allow the boot to be easily removed during servicing while maintaining its structural integrity. The lip and recess engagement mechanisms provide controlled attachment and detachment points that prevent random tearing or damage during field operations.

AI summary
An apparatus and methods are provided for a pliable boot for Deutsch connectors. The boot is made of rubber or any other material that is amenable to being easily pushed onto and removed from a Deutsch connector. The boot comprises a hollow member extending from cylindrical portion to an adapter portion. The cylindrical portion receives any of a group of electrical wires that are routed into the Deutsch connector. The adapter portion includes a back opening that receives a shrink boot adapter comprising the Deutsch connector. The adapter portion includes a lip to engage with a recess disposed around the shrink boot adapter. A transition portion is disposed between the cylindrical portion and the adapter portion. An interior shape of the boot increases in size along a length of the transition portion from the cylindrical portion to the adapter portion.
