Clip-on Bracket for Plug-in Connector with 90° Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip-on brackets for plug-in connectors have limited angular range and are either cumbersome in design or expensive to produce, failing to efficiently direct cables away from the connector housing while maintaining a compact profile.
Innovation Solution
A compact clip-on bracket with a first end that engages the cable outlet and a second end that engages the cable sheath, connected via two webs that allow for a large bending angle of up to 90°, featuring a frame-shaped open structure and optional polygon or arc designs, with fastening means like cable ties for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed cable outlet element design is used to protect individual conductors, then conductor protection is improved, but the angular range is limited and cannot achieve 90° bending
Solution Approach 1:
The cable outlet element is divided into two functional parts: a protective cover that encloses the conductors for safety, and a separate bracket structure that provides the bending function. This segmentation allows the protective cover to maintain conductor protection while the bracket independently achieves the required angular range including 90° bending.
Solution Approach 2:
A bracket element is introduced as an intermediary component between the cable outlet element and the cable. This bracket serves as a mediator that directs the cable at the desired angle while the cable outlet element maintains its protective function, thus resolving the conflict between protection and angular flexibility.
2Reliability
If a separate cable outlet element with strain relief is used, then cable protection is improved, but the design becomes larger and more cumbersome
Solution Approach 1:
The bracket is designed to integrate multiple functions: it provides cable direction control, acts as a strain relief element, and serves as a mounting structure. By merging these functions into a single component rather than using separate elements, the design achieves cable protection without increasing overall complexity or size.
Solution Approach 2:
The bracket is designed as a multi-functional element that simultaneously provides mechanical support, cable routing, strain relief, and angular positioning. This universality eliminates the need for additional separate components, reducing design complexity while maintaining cable protection.
3Ease of operation
If a semi-open geometry clip-on bracket is used as a retrofit solution, then installation flexibility is improved, but the angular range is limited
Solution Approach 1:
The bracket incorporates a snap-fit mechanism with elastic deformation capability that allows it to dynamically adapt to different cable angles. The bracket can be installed in a relaxed state and then deforms elastically to secure cables at various angles including 90°, providing both installation flexibility and extended angular range.
Solution Approach 2:
The bracket design allows for parameter changes in its geometric configuration, particularly in the angle of its bending surfaces. By optimizing these geometric parameters, the bracket achieves both ease of installation and the capability to support a wide angular range up to 90°.
4Volume of moving object
If a compact clip-on bracket with open structure is used, then the profile is reduced and space is saved, but attachment security must be ensured
Solution Approach 1:
The bracket includes pre-formed engagement features such as snap-fit elements and positioning ribs that are prepared in advance during manufacturing. These preliminary structures ensure that when the bracket is installed, secure attachment is achieved automatically without requiring additional fastening components, thus maintaining compact dimensions while ensuring reliability.

AI summary
A clip-on bracket for a cable outlet of a plug-in connector, wherein the clip-on bracket has a first end that can be brought into touching contact with a cable outlet of the plug-in connector, and wherein the clip-on bracket, has a second end that can be brought into touching contact with the cable outlet or with a cable sheath of the cable connected to the plug-in connector. The first end is connected to the second end via two webs, so that the cable outlet and/or the connected cable is only partially covered by the webs of the clip-on bracket.
