Electrical Connector Housing with Thinned Hole Walls for Multi-Terminal Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electrical connectors can only accommodate plug-fitted terminals of one line type, leading to a complex structure and poor adaptability when multiple line types are used simultaneously.
Innovation Solution
An electrical connector housing assembly with plug-fitting holes and a rear-end cap that accommodates different line types by providing slots and thinned hole walls for various terminal structures, allowing for the simultaneous use of plug-fitted terminals with wide-flat and cylindrical line bodies, and a rear-end cap that secures and supports the terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electrical connectors use separate sockets for different line types, then each socket can accommodate its specific terminal type, but the overall structure becomes complex and adaptability decreases
Solution Approach 1:
The housing is designed with a universal plug-fitting hole structure that can accommodate multiple line types (round, square, flat) through a single unified interface. The hole walls can be selectively thinned to match different terminal shapes, allowing one housing to serve multiple functions and adapt to various connecting lines without requiring separate specialized sockets for each line type.
2Adaptability or versatility
If the housing accommodates multiple line types through selective thinning of hole walls, then adaptability to different terminal structures is improved, but manufacturing complexity increases
Solution Approach 1:
The housing hole walls are segmented into different regions that can be selectively thinned to accommodate various terminal shapes. Instead of manufacturing completely different housings for each line type, the housing is divided into zones where specific wall sections are removed or thinned to match the required terminal geometry, simplifying the manufacturing process while maintaining adaptability.
3Reliability
If the rear-end cap covers all plug-fitting holes, then terminal fixing and support are improved, but accessibility for cable management becomes more difficult
Solution Approach 1:
The rear-end cap is designed with differentiated regions: solid covering portions over most plug-fitting holes to provide stable terminal fixing and support, and selective opening portions or gaps at specific locations to allow cable access and management. This local differentiation of the cap's structure enables it to simultaneously fulfill both the protective/supportive function and the operational accessibility requirement.

AI summary
The present application discloses an electrical connector housing assembly and an electrical connector. The electrical connector housing assembly comprises a housing provided with several plug-fitting holes for arranging plug-fitted terminals; and a rear-end cap detachably mounted at a rear end of the housing and covering part of the plug-fitting holes. The electrical connector comprises an electrical connector housing assembly and a plurality of inserted plug-fitted terminals. According to the electrical connector housing assembly of the present disclosure, by providing slots on hole walls among a row of plug-fitting holes wherein all slots forming a communicative elongated groove which may receive plug-fitted terminals of a wide-flat line body unbranched at a front end; by arranging the hole walls between plug-fitting holes to be thinned to receive plug-fitted terminals of a wide-flat line body branched at the front end; by plugging a plug-fitted terminal of a cylindrical line body structure into a single plug-fitting hole, the electrical connector housing assembly and the electrical connector of the present disclosure are enabled to be simultaneously adapted to three plug-fitted terminals of different line body structures.
