Plug Connector Holding Frame With Slot-Mounted Wall Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for contact inserts in plug connectors lack a simplified structural design that facilitates easy and secure mounting of wall segments, leading to potential misalignment and instability of contact inserts.
Innovation Solution
A holding frame design featuring a main frame with slot-like cut-outs on its side walls for receiving wall segments, allowing for easy attachment and secure fastening of contact inserts through resilient wall segments with tapered and curved edges, which apply compressive forces to center and hold the inserts in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional holding frame designs with multiple recesses and projection elements are used, then contact inserts can be latched and held on the holding frame, but the structural design becomes complex and mounting becomes difficult
Solution Approach 1:
The holding frame is divided into a main frame and multiple separate wall segments. Each wall segment can be independently mounted onto the main frame via slot-like cut-outs, allowing for simplified assembly and disassembly while maintaining reliable contact insert holding capability through the modular structure
Solution Approach 2:
The wall segments are extracted as separate components from the main frame structure, each equipped with fastening regions for contact inserts. This separation allows the wall segments to be pre-assembled with contact inserts and then easily attached to the main frame through the slot-like cut-outs, reducing overall structural complexity
2Reliability
If multiple recesses and projection elements are provided for latching contact inserts, then contact inserts can be securely held, but alignment precision deteriorates due to potential misalignment
Solution Approach 1:
The wall segments act as intermediary components between the main frame and contact inserts. Each wall segment includes fastening regions that engage with projection elements of contact inserts, providing a controlled interface that ensures precise alignment and positioning while maintaining secure holding capability
Solution Approach 2:
The wall segments are designed with pre-formed fastening regions and slot-like cut-outs that guide the assembly process. The slot-like cut-outs on the main frame provide predetermined mounting positions for the wall segments, ensuring accurate alignment before final assembly with contact inserts
3Reliability
If traditional latching mechanisms with multiple recesses are used, then contact inserts can be locked on the holding frame, but the mounting process becomes time-consuming
Solution Approach 1:
The holding frame structure is segmented into a main frame and detachable wall segments that can be quickly attached and detached. The slot-like cut-outs enable rapid mounting of wall segments without complex latching operations, significantly reducing assembly time while maintaining secure holding capability
Solution Approach 2:
The wall segments are designed with dynamic mounting capability through the slot-like cut-outs, allowing for quick insertion and removal. This dynamic structure enables rapid reconfiguration of the holding frame by simply attaching or detaching wall segments, reducing mounting time while ensuring reliable contact insert holding during use

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 multiple wall segments, each of which has a fastening region via which the contact inserts that are inserted into the interior of the main frame are holdable on the main frame. Each wall segment of the multiple wall segments are arranged on a receiving section formed on the first side wall or on the second side wall. Each receiving section has a slot-like cutout.
