Modular Jack Rear Wall Engagement for Compact Surface Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing modular jacks with engagement structures on the side walls increase the width, compromising surface-mounting performance due to the need for resilient deformation, which affects their compactness and mounting efficiency.
Innovation Solution
A modular jack design featuring a housing with a terminal holder, where the terminal holder includes a connector terminal and a latch section, with specific through-holes and engaged portions on the rear wall allowing for compact assembly without protrusion, enhancing surface-mounting capabilities by maintaining a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an engagement portion is provided at the outer side of the side wall portion for engagement with the terminal module, then connection reliability between the main body and terminal module is improved, but the widthwise dimension of the modular jack is increased, thereby degrading surface-mounting performance
Solution Approach 1:
The patent moves the engagement portion from the lateral outer side of the side wall to the rear wall surface, changing the spatial dimension of engagement. This allows the engagement structure to be positioned at the rear of the device rather than extending the width, thereby maintaining connection reliability while preserving compact widthwise dimensions for surface-mounting compatibility
2Adaptability or versatility
If the side wall portion is resiliently deformed for connection between the main body and terminal module, then connection flexibility is improved, but the structural complexity and risk of deformation are increased
Solution Approach 1:
The patent extracts the resilient deformation function from the side wall portion and relocates it to the rear wall. By separating the engagement function from the lateral structure and placing it on the rear wall, the design reduces structural complexity while maintaining connection flexibility through the rear wall's resilient properties

AI summary
A downsized modular jack with high surface-mounting performance. The modular jack has a housing and a terminal holder assembled thereto. The housing has a rear wall formed with a terminal insertion through-hole extending through a thickness of the rear wall, and a latch section insertion through-hole positioned beside the terminal insertion through-hole. The latch section insertion through-hole has an engaged portion positioned within the thickness of the rear wall. The terminal holder has a connector terminal extending through the terminal insertion through-hole and a latch section engaged with the engaged portion and positioned within the thickness of the rear wall upon assembly of the terminal holder into the housing.
