Modular Connector Housing With Reversible Stacking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector housings lack an efficient and secure method for assembling multiple modules to form a stable and modular connector housing system.
Innovation Solution
A stacking module with complementary fasteners and half-cavities allows for the assembly of multiple modules, forming complete cavities for housing connector parts, and includes lower and upper end modules for additional assembly options, using latching hooks and protrusions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple connector modules are assembled using conventional fastening methods (snap-fitting, screwing, or other types), then the connector housing can be formed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The connector housing is divided into multiple independent modules (first module, second module, third module) that can be manufactured separately and assembled in a standardized sequence. Each module has identical engagement features that allow for repetitive, quick assembly without complex fastening mechanisms.
Solution Approach 2:
Multiple engagement features (lugs and corresponding recesses) are combined into a single integrated fastening interface between modules. This merging of fastening functions into unified protrusion-recess pairs eliminates the need for separate snap-fitting, screwing, or other fastening operations.
2Ease of operation
If connector modules are designed for easy assembly, then the assembly process is simplified, but the structural stability and rigidity of the connector housing may be compromised
Solution Approach 1:
The engagement features are strategically positioned at multiple locations (front engagement lugs at the front face, rear engagement lugs at the rear face, and side engagement lugs on lateral faces) to provide localized stability points throughout the connector housing structure, ensuring rigid alignment while maintaining easy assembly.
Solution Approach 2:
Instead of using complex fastening mechanisms that require active engagement actions, the design uses passive interference-fit lugs and recesses that automatically engage when modules are brought together, reversing the conventional approach of requiring active fastening operations.
3Ease of repair
If conventional fastening methods are used to attach adjacent housings, then the connector housing can be assembled, but disassembly and replacement of connector parts becomes difficult
Solution Approach 1:
The engagement lugs are designed with elastic deformation capability, allowing them to flex during assembly and disassembly operations. This dynamic behavior enables reliable connection during normal use while permitting easy separation when needed for repair or replacement, without compromising connection integrity.

AI summary
A stacking module for a connector housing which can be assembled with another, identical stacking module in a stack to form the connector housing. The stacking module comprises a base plate with an upper face and a lower face, wherein at a first edge of the base plate an upper side wall extends away from the base plate's upper face. A first fastener and a first counter fastener are provided at one of the first and the second edges of the base plate. A lower side wall extends at a second edge of the base plate away from the lower face of the base plate, the second edge being opposite the first edge. A lower end module and an upper end module can be assembled with the stacking module.
