Waterproof Electrical Cable Connector With Standoff Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with blade type contacts face issues with waterproofing when wires of larger diameters are soldered, as the fluid glue cannot fully fill the space behind the housing, compromising the seal.
Innovation Solution
The design incorporates an insulative housing with slit type passageways for blade type contacts, standoffs for exposed inner conductors, and a waterproof glue plate that fills the cavity behind the rear face, ensuring complete sealing and effective waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires of larger diameter are soldered upon the tails of blade type contacts behind the rear face of the housing, then the electrical connection capability is improved, but the waterproofing effect deteriorates because the fluidal glue cannot completely fill the space behind the rear face
Solution Approach 1:
The patent introduces a new spatial dimension by adding standoffs that protrude from the rear face into the cavity. These standoffs create multiple levels and compartments within the single cavity space, allowing the glue to fill areas that would otherwise be inaccessible due to large wire diameters. This dimensional transformation converts a two-dimensional flat sealing surface into a three-dimensional multi-level sealing structure.
Solution Approach 2:
The patent segments the continuous cavity space into multiple smaller compartments by introducing standoffs. Each standoff creates an isolated gluing area, dividing the large open space into several smaller zones that can be independently filled with glue. This segmentation ensures that even with large diameter wires present, the glue can completely fill each smaller compartment, achieving complete sealing.
2Quantity of substance
If the diameter of the wire becomes larger, then the current carrying capacity is improved, but the configuration of the space behind the rear face becomes relatively odd, preventing complete filling with fluidal glue
Solution Approach 1:
The standoffs introduce a vertical dimension (protrusion into the cavity) that transforms the flat two-dimensional space arrangement into a three-dimensional multi-level structure. This allows the glue to access and fill spaces around large diameter wires that would be inaccessible in a flat configuration, accommodating various wire sizes without compromising sealing.
Solution Approach 2:
The standoffs change the geometric parameters of the cavity space by introducing protruding structures with specific heights and spacing. This parameter modification creates optimal gluing zones that adapt to different wire diameters, allowing the glue to completely fill the space regardless of wire size variations.

AI summary
An electrical connector includes an insulative housing, a plurality of slit type passageways, a plurality of blade type contacts retained with the corresponding slit type passageways, respectively, and a plurality of wires having the inner conductors soldered upon the tails of the contacts behind the rear face of the housing. The rear face forms a plurality of standoffs on which the front ends of the exposed inner conductor abut, respectively. A waterproof glue plate fills the back space of the housing behind the rear face to enclose the exposed inner conductors and the corresponding tails and seal the rear face of the housing.
