Divided Connector Positioning Frame Eliminates Backlash
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional divided connectors with multiple housing components suffer from backlash and inadequate holding strength due to production tolerances, leading to potential deformation and uneven contact in terminals when tension is applied.
Innovation Solution
A divided connector design that eliminates the need for a front holder by using an inner housing with a terminal positioning regulating wall and a front part positioning frame in the outer housing, ensuring accurate positioning and strong holding with fewer parts, and includes engaging piece regulating bottom plates for double engagement and enhanced reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple housing components (inner housing, outer housing, front holder) are used in a divided connector, then the terminal can be positioned and held, but production tolerances accumulate causing backlash between components
Solution Approach 1:
The patent merges the front holder function into the outer housing by providing a front part positioning frame that protrudes from the terminal positioning regulating wall. This integration eliminates the separate front holder component, reducing the total number of parts from three (inner housing, outer housing, front holder) to two (inner housing, outer housing), while maintaining terminal positioning accuracy by directly positioning the terminal main body front part against the positioning frame.
2Strength
If multiple housing components are used to hold the terminal, then the terminal can be secured, but the cumulative backlash reduces holding strength
Solution Approach 1:
By integrating the front part positioning frame into the outer housing, the patent eliminates the interface between the front holder and outer housing that would otherwise contribute to cumulative backlash. This merging ensures that the terminal is held by the inner housing and outer housing as a unified structure, maximizing holding strength without the degradation caused by multiple component interfaces.
3Measurement precision
If a front holder is used to position the terminal main body front part, then positioning can be achieved, but the cumulative backlash from multiple components causes terminal deformation
Solution Approach 1:
The patent eliminates the front holder component by integrating its positioning function into the outer housing through the front part positioning frame. This frame protrudes from the terminal positioning regulating wall and directly positions the terminal main body front part, achieving the same positioning accuracy with fewer components and eliminating the source of cumulative backlash that would cause terminal deformation.

AI summary
A divided connector, comprises a terminal having an electric contact part protruding from a main body front part and an electric wire attached under pressure to a main body rear part; an inner housing that allows the terminal inserted into an inner part to be engaged with a terminal engaging piece and attached and the main body front part to protrude from a front end; an outer housing that allows the inner housing inserted into an inner part from a rear part to be engaged with a flexible engaging piece and attached; a terminal positioning regulating wall provided in the outer housing and having a contact part inserting hole for inserting the electric contact part; and a front part positioning frame protruding in the rear surface of the terminal positioning regulating wall correspondingly to the contact part inserting hole to enclose and position the main body front part.
