Low Profile Cable Connector Elastic Arm Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial cable connectors are too high and lack reliable connection quality due to the coaxial cable being sandwiched by a lid and soldering portion, which hinders miniaturization and ensures connection stability.
Innovation Solution
A low-profile cable connector design featuring an insulating housing with elastic arms that clip the inner conductor of the cable horizontally, eliminating the need for an insulating lid and ensuring stable connection through a shell that pushes the elastic arms to secure the contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coaxial cable is sandwiched by the lid and the soldering portion of the contact, then the connection quality between the coaxial cable and the contact can be ensured, but the height of the coaxial cable connector becomes high and cannot meet the miniaturization tendency
Solution Approach 1:
The patent removes the insulating lid from the traditional connector structure. Instead of sandwiching the cable between the lid and soldering portion, the cable is directly clamped by the elastic arm and soldering portion, eliminating the need for the lid and reducing connector height while maintaining connection reliability
Solution Approach 2:
The patent introduces an elastic arm that can dynamically adjust its position. The elastic arm is pushed by the shell to clamp the cable horizontally, providing flexible positioning and reliable connection without requiring the rigid lid structure, thus achieving both connection quality and miniaturization
2Ease of manufacture
If the coaxial cable is put on the flat soldering portion and capable of moving freely before fixing, then the assembly process is simple, but the connection quality between the coaxial cable and the contact cannot be ensured
Solution Approach 1:
The patent incorporates an elastic arm that is pre-configured to push against the cable and engage with the soldering portion. This preliminary action ensures that as soon as the cable is placed, it is automatically clamped horizontally with precise positioning, maintaining both assembly simplicity and connection reliability
Solution Approach 2:
The patent applies localized clamping force through the elastic arm at the specific position where the cable contacts the soldering portion. This localized action ensures proper horizontal alignment and secure connection without requiring complex assembly procedures, achieving both ease of manufacture and connection quality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a low-profile connector with enhanced connection stability by securely clipping the cable's inner conductor, ensuring reliable contact and reducing the connector's height while maintaining connection quality.
Implementation Method 1
The insulating housing includes an elastic arm extending into the receiving room and located beside the connecting portion of the contact. The back portion of the shell includes a pushing portion pushing the elastic arm to press the connecting portion of the contact.
