Waterproof Connector Spacing Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof connectors face challenges in maintaining effective sealability due to irregular spacings between electrical wires, which hinder uniform waterproofing, especially when the spacing between terminals is reduced, leading to reduced seal effectiveness.
Innovation Solution
A waterproof connector design featuring a spacing adjusting portion with piled-up plates and a seal member that adjusts the spacing between electrical wires to ensure a consistent, larger spacing for effective waterproofing, utilizing a wire seal with lead-out and spacing adjusting plates to accommodate varying terminal spacings and maintain water-tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the spacing between terminals is reduced to achieve smaller connector size, then the connector size is reduced, but the spacing between electrical wires becomes insufficient for effective waterproofing
Solution Approach 1:
The patent introduces a spacing adjusting portion as an intermediary component between the terminal receiving portion and the seal member. This spacing adjusting portion includes adjusting plates that can be positioned to increase the spacing between electrical wires, ensuring sufficient space for the seal member to effectively waterproof the connector even when terminals are closely spaced.
2Volume of moving object
If the spacing between terminals is reduced, then the connector size is reduced, but the uniform and effective waterproofing becomes difficult due to irregular wire spacings
Solution Approach 1:
The patent applies local quality by making the spacing adjusting portion adjustable rather than fixed. The adjusting plates can be positioned at different locations to locally increase spacing where needed, allowing the seal member to achieve uniform waterproofing across all wire positions regardless of the original irregular terminal spacing.
Solution Approach 2:
The spacing adjusting portion is designed to be dynamically adjustable, allowing the spacing between electrical wires to be modified according to actual installation needs. This dynamic adjustment capability ensures that uniform waterproofing can be achieved even when terminal spacings vary, without requiring precise manufacturing tolerances.
3Reliability
If a seal member with sufficient thickness is used to waterproof irregularly spaced wires, then waterproofing effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent segments the connector structure into distinct functional portions: terminal receiving portion, spacing adjusting portion, and seal member portion. The spacing adjusting portion is further divided into multiple adjustable plates. This segmentation allows each component to perform its specific function efficiently, maintaining waterproofing effectiveness while organizing complexity into manageable, modular sections.

AI summary
The present invention is to provide a waterproof connector having an adjusted spacing between terminals or electrical wires for achieving an effective waterproof. The electrical wires received in a terminal receiving portion of an outer housing are guided to a wire seal fit portion, while the electrical wires are pressed with wire holders (displacement limit portions). The electrical wires are then passed through a holder (spacing adjusting portion), a seal member, and another holder (lead-out portion) of a wire seal in the wire seal fit portion. The wire seal is fitted into the wire seal fit portion for achieving waterproof of the waterproof connector. The electrical wires guided out of the lead-out portion have an equal spacing therebetween by expansion of the spacings between the electrical wires or displacements thereof. The equal spacing ensures insertion of the seal member and provides the effective waterproof.
