Crimped Connector Housing Structure for Deformation-Free PCB Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors suffer from deformation under external force during crimping, leading to damage and poor signal integrity due to signal distortion and low reliability caused by a nut falling off or being difficult to install.
Innovation Solution
A connector design featuring a housing with a shoulder to withstand external force, preventing deformation during crimping, and a shielding member that eliminates gaps between fasteners and the housing, enhancing signal integrity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is crimped into a circuit board under external force, then the connector can be securely installed, but the connector is prone to deform and get damaged
Solution Approach 1:
The connector housing is segmented into multiple functional regions: a reinforcing rib structure that divides the housing into multiple support zones, a distinct crimping area for finger attachment, and a body portion for circuit board insertion. This segmentation allows each region to handle specific forces independently, preventing overall deformation while maintaining installation security.
Solution Approach 2:
The reinforcing rib structure is designed beforehand to absorb and distribute external forces before they can cause deformation to the connector housing. The ribs act as pre-positioned structural cushions that reinforce the housing during the crimping process, preventing damage before it occurs.
2Reliability
If a nut is installed inside the connector to secure a wire with high torque, then the wire can be firmly fixed, but signal distortion occurs due to gap between nut and connector
Solution Approach 1:
The nut component is completely removed from the connector design. Instead of using a separate nut to secure the wire, the wire is directly attached to the housing or integrated fastening structure. This eliminates the gap between nut and connector that caused signal distortion, while maintaining secure wire fixation through the integrated design.
Solution Approach 2:
The wire fastening function is merged with the housing structure itself. The housing incorporates integrated fastening features such as recesses, clips, or direct crimping areas that combine the structural support and wire securing functions into a single unified component, eliminating the need for separate nuts and preventing signal distortion.
3Volume of moving object
If a small-sized nut is used to secure the wire, then the connector size can be reduced, but the nut is easy to fall off and difficult to install
Solution Approach 1:
The wire fastening function is merged with the housing structure itself. The housing incorporates integrated fastening features such as recesses, clips, or direct crimping areas that combine the structural support and wire securing functions into a single unified component, eliminating the need for separate nuts and preventing signal distortion.
Solution Approach 2:
The housing structure provides self-contained wire fastening capabilities through integrated features. The housing itself serves as both the structural component and the wire securing mechanism, eliminating the need for separate fastening components that would require separate installation steps.

AI summary
A connector comprises a first fastener and a housing. The first fastener is arranged on the housing and is adapted to secure a wire between the housing and the first fastener. The housing includes at least one side wall, and a finger extending from one end of the at least one side wall. The at least one side wall includes a shoulder adapted to withstand external force applied to crimp the finger into a circuit board. A height from the shoulder to the one end of the at least one side wall is sufficient to prevent deformation of the housing during crimping of the finger to the circuit board.
