Plug Connector Holding Frame With Segmented Insert Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for plug connectors lack a simplified structural design that effectively secures contact inserts, leading to potential misalignment and instability.
Innovation Solution
A holding frame with a main frame and multiple wall segments, where each wall segment has a fastening region that overlaps the opening for a contact insert's projection element, ensuring secure holding and improved positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact inserts are held on the holding frame using recesses and projection elements, then the contact inserts can be securely locked, but the structure becomes complex with multiple components
Solution Approach 1:
The wall segment combines multiple functions into a single integrated component: it provides the opening for receiving the projection element, the fastening region for securing the contact insert, and the attachment interface to the main frame. This merging eliminates the need for separate recesses and fastening components, reducing structural complexity while maintaining securement reliability.
Solution Approach 2:
The holding frame is divided into a main frame and detachable wall segments that can be individually manufactured and assembled. Each wall segment is a separate module that can be attached to the main frame, allowing for simplified manufacturing and assembly while providing the complete functional structure needed for securing contact inserts.
2Manufacturing precision
If multiple wall segments are used to secure contact inserts, then positioning accuracy improves, but the manufacturing process becomes more complex
Solution Approach 1:
The wall segments are pre-formed with the opening and fastening region in their final positions and orientations. This preliminary preparation allows for precise positioning of contact inserts during assembly, as the geometric features are already correctly positioned rather than requiring complex adjustment or alignment procedures during manufacturing.
Solution Approach 2:
By segmenting the holding frame into a main frame and separate wall segments, each component can be manufactured independently using optimized processes. The wall segments can be produced with high precision features (opening and fastening region) using suitable manufacturing methods, then attached to the main frame, simplifying the overall manufacturing process while maintaining positioning accuracy.

AI summary
A holding frame for a plug connector, for receiving contact inserts, includes: a main frame, which has a first side wall, a second side wall opposite the first side wall, a first end wall, and a second end wall opposite the first end wall, the first side wall, the second side wall, the first end wall, and the second end wall enclosing an interior of the main frame into which the contact inserts are insertable in an insertion direction; and a plurality of wall segments, each of which has a fastening region via which the contact inserts which are inserted into the interior of the main frame are holdable on the main frame. In a mounted position, each wall segment of the plurality of wall segments is arranged on a receiving section formed on the first side wall or on the second side wall.
