Easy-to-assemble connector with straight signal insertion holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors are difficult to assemble, especially in limited spaces, due to the complexity of inserting signal terminals and connecting electric wires, which increases the defect rate and requires significant force to establish a conductive connection, especially when the number of signal terminals exceeds twenty.
Innovation Solution
A connector design featuring a first main body with straight signal insertion holes and power insertion holes, where signal hole terminals have connecting tubes with electric wires that are easily inserted through a flat portion and fixed with glue, allowing for easy assembly and reduced resistance with the use of crown springs and a covering member to facilitate the insertion of multiple terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal terminals are inserted into cone-shaped bores from the rear side of the female connector, then electrically conductive connection can be established, but assembly becomes difficult due to limited space in the casing
Solution Approach 1:
The patent inverts the conventional insertion direction by inserting signal terminals from the front side of the female connector rather than from the rear side. The front side insertion allows operators to access terminal installation from the outside of the casing, eliminating the difficulty of working within the limited rear space while maintaining reliable electrical connection through the cone-shaped bores
2Adaptability or versatility
If multiple signal terminals are installed in the limited space of the female connector casing, then connectivity increases, but assembly complexity and defect rate increase
Solution Approach 1:
The patent changes the dimensional approach to terminal installation by transitioning from rear-side insertion (constrained by internal casing depth) to front-side insertion (accessible from external surface). This dimensional shift allows multiple signal terminals to be installed simultaneously or sequentially with ease, reducing assembly complexity while maintaining high connectivity capacity
3Reliability
If all signal poles press against elastic claws simultaneously during connector connection, then complete electrical connection is achieved, but considerable force is required that cannot be applied by bare hands when terminals exceed twenty
Solution Approach 1:
The patent applies preliminary action by pre-configuring the elastic claws with initial outward expansion force before connection. When the male connector approaches, the elastic claws are already positioned to flex inward, distributing the insertion force gradually rather than requiring all signal poles to overcome maximum resistance simultaneously. This reduces peak force requirements making assembly feasible by bare hands

Function Achieved in This Case
The design simplifies the assembly process, reduces the difficulty in inserting signal terminals and connecting electric wires, increases the number of terminals that can be installed in a given volume, and enhances the durability and water-resistance of the connector while maintaining high electrical conductivity.
