Movable Blocking Element for Secure Plug Connector Holding Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for plug connector modules lack a clear open position for easy assembly, are prone to accidental opening, and do not provide a defined electrical contact for grounding, making them difficult to handle and use, especially for inexperienced users.
Innovation Solution
A holding frame with two angled halves connected via a jointed connection, featuring a movable blocking element with latching hooks and a grounding socket, allowing for easy assembly and secure locking in a closed position, and enabling easy removal of plug connector modules using a slotted screwdriver for unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a jointed connection is used to connect the two halves, then the holding frame can be assembled and disassembled, but there is no clearly defined open position for easy assembly and the frame can inadvertently open
Solution Approach 1:
The blocking element is designed to automatically engage with the blocking surface when the holding frame is closed, creating a self-locking mechanism that prevents inadvertent opening without requiring additional manual securing steps
Solution Approach 2:
The blocking element acts as an intermediary component between the two halves, providing a mechanical interface that defines the closed position and prevents accidental opening while allowing controlled assembly and disassembly
2Reliability
If a separate securing means is used to secure the halves in closed position, then the holding frame can be secured, but the securing means can get lost with repeated use
Solution Approach 1:
The blocking element is integrated into the jointed connection structure itself, merging the securing function with the existing connection mechanism and eliminating the need for separate removable securing components that could be lost
3Reliability
If a lock screw is used to secure the joint in closed position, then the holding frame can be secured, but it is tricky to handle and requires manual securing until screws are tightened
Solution Approach 1:
The blocking element automatically engages with the blocking surface when the holding frame is closed, creating a self-locking mechanism that eliminates the need for manual screw tightening and handling
4Ease of manufacture
If a purely jointed connection is used, then the halves can be connected, but there is no defined electrical contact between the halves for grounding purposes
Solution Approach 1:
The blocking element is designed to serve multiple functions: it provides mechanical blocking to maintain the closed position and simultaneously creates defined electrical contact between the halves, enabling grounding capabilities without adding separate components

AI summary
A holding frame is provided, into which plug connector modules can be inserted, wherein the holder frame comprises or consists of two halves which can be connected to each other, a first half and a second half, wherein the halves each have a lateral surface and a cover surface, wherein the holding frame has at least one first blocking element, via which the halves can be fixed in a closed position, and wherein the at least one blocking element is movably held on the first half or on the second half. The blocking element is held on the first half or on the second half in a displaceable or rotatable or pivotable manner.
