Electrical Connector Inclined Insertion Mating Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face challenges in mating workability, requiring a 90-degree change in movement direction, leading to longer mating times and increased likelihood of failure.
Innovation Solution
The electrical connector design features a base and socket with specific protrusions and engagement projections that allow for inclined insertion and rearward movement, followed by downward displacement, ensuring secure accommodation and improved resistance to wire displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the socket is inserted with a 90-degree change in movement direction between first and second matings, then the connector achieves secure locking, but the mating workability deteriorates and the mating time increases
Solution Approach 1:
The mating process is divided into two sequential stages: first mating where the socket is inserted in the thickness direction with projections fitting into communication grooves, and second mating where the socket moves in the depth direction with projections moving along recesses. This segmentation allows each stage to perform a specific function while maintaining overall reliability without requiring complex 90-degree directional changes.
Solution Approach 2:
The invention transitions from requiring 90-degree directional changes to achieving secure locking by utilizing movement along the same axis (depth direction) with different phases. The first mating establishes initial connection in the thickness direction, while the second mating secures the connection by moving along the depth direction, eliminating the need for orthogonal movement changes.
2Reliability
If the socket is inserted with a 90-degree change in movement direction, then the connector achieves secure locking, but the mating process becomes more time-consuming
Solution Approach 1:
The mating process is segmented into two sequential stages: first mating where the socket is inserted in the thickness direction with projections fitting into communication grooves, and second mating where the socket moves in the depth direction with projections moving along recesses. This segmentation allows each stage to perform a specific function while maintaining overall reliability without requiring complex 90-degree directional changes.
Solution Approach 2:
The mating process maintains continuous useful action by having the socket move continuously in the depth direction during the second mating, with projections moving along recesses to secure the connection. This continuous movement along the same axis eliminates time-wasting 90-degree directional changes while maintaining secure locking.

AI summary
An electrical connector includes a base including a base housing, and a socket including a socket housing. Each of two socket side walls of the socket housing is provided with a first protrusion, and a distance L4 between two base side walls is equal to or larger than a distance L2 between the respective leading ends of the first protrusions. Each of two base side walls is provided with a first engagement projection on its inner surface, and a distance L1 between the respective leading ends of the first engagement projections is smaller than the distance L2 between the respective leading ends of the first protrusions, and the distance L1 is equal to or larger than a distance L3 between the two socket side walls. While the socket is completely accommodated in a socket accommodation chamber, each first protrusion is positioned below the corresponding first engagement projection.
