Connector Assistant Fitting Elastic Fixing Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire-to-board connectors are prone to damage when wires are lifted up due to insufficient strength in the mounting assistant fitting.
Innovation Solution
The connector design includes a cantilever-shaped fixing portion that is elastically displaceable and supported by a held portion, with displacement regulating elements to prevent excessive deformation, and a leg portion soldered to the board for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mounting assistant fitting is made simple in structure, then the ease of manufacture is improved, but the strength and damage resistance deteriorate
Solution Approach 1:
The mounting assistant fitting is divided into multiple functional portions: a held portion attached to the receptacle housing, a fixing portion that engages with the plug connector, and a displacement regulating portion that controls elastic deformation. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural simplicity.
Solution Approach 2:
The fixing portion is designed with elastic displacement capability, allowing it to dynamically adjust during the locking process. The displacement regulating portion controls this elasticity to prevent excessive deformation, combining flexibility with strength protection.
2Reliability
If the fixing portion is made elastically displaceable to accommodate wire movement, then the reliability is improved, but the displacement control becomes more difficult
Solution Approach 1:
The fixing portion is designed to elastically displace in response to wire movement, maintaining reliable engagement. The displacement regulating portion provides passive geometric constraints that automatically limit displacement without requiring active control mechanisms.
Solution Approach 2:
The elastic displacement and regulation features are integrated into the mounting assistant fitting itself, allowing it to self-adjust and self-regulate during operation without requiring external control systems or additional complex components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively prevents damage to the assistant fittings by regulating displacement and maintaining the locked state even when wires are raised, while allowing intentional release.
Implementation Method 1
the fixing portion is formed to be elastically displaceable in a direction approaching the held portion
Implementation Method 2
the assistant fitting includes a leg portion that is soldered to the connector mounting surface of the board

AI summary
A receptacle connector (3) includes a receptacle contact (7) corresponding to a plug contact (4), a receptacle housing (8) that holds the receptacle contact (7), and an assistant fitting (9) attached to the receptacle housing (8), and is mounted on a connector mounting surface (10a) of a circuit board (10). The assistant fitting (9) includes at least a held portion (30), a fixing portion (31), and a vertical displacement regulating portion (42). The held portion (30) is a portion that is held by the receptacle housing (8). The fixing portion (31) is a portion that is hooked to the plug housing (5) to thereby fix the plug connector (2) to the receptacle connector (3). The vertical displacement regulating portion (42) is a portion that regulates a displacement of the fixing portion (31) in a direction away from the connector mounting surface (10a) of the circuit board (10).
