Cable Connector Latch Elastic Arm Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies face challenges in achieving effective grounding due to limited space within the plug connector, leading to complex latch member designs that are either rigid or lack elasticity, affecting the grounding effect and high-frequency transmission.
Innovation Solution
The cable connector assembly incorporates a latch member with backward elastic arms that protrude out of the insulating body to elastically urge against a second metal shell, ensuring good contact and stable grounding, while also optimizing internal space and manufacturing simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the urging portion is placed inside the first metal shell, then the grounding effect is achieved, but the latch member shape becomes complex and manufacturing becomes difficult
Solution Approach 1:
The urging portion is repositioned from inside the first metal shell to the rear end of the latch member, extending in a different spatial dimension. This dimensional relocation allows the urging function to be achieved without complicating the overall latch member structure, making manufacturing easier while maintaining grounding effectiveness.
2Reliability
If the urging portion is placed inside the first metal shell, then the grounding effect is achieved, but the latch member loses elasticity and becomes rigid
Solution Approach 1:
The urging portion is extracted from the constrained interior space of the first metal shell and repositioned to the rear end of the latch member. This extraction allows the urging portion to maintain its elastic properties by having sufficient space to deform, while still achieving the grounding function through contact with the second metal shell.
3Reliability
If the latch member urges against the metal shell too tightly, then contact is achieved, but the latch member deforms or assembly becomes difficult
Solution Approach 1:
The urging portion is designed as an elastic element that dynamically adjusts its contact force with the second metal shell. When assembled, the elastic urging portion automatically applies appropriate pressure to ensure good electrical contact, while its elasticity allows for easy assembly by accommodating slight variations in positioning and tolerance.
4Ease of operation
If the latch member urges against the metal shell too loose, then assembly is easy, but contact quality deteriorates and grounding effect is affected
Solution Approach 1:
The elastic urging portion serves itself by automatically adjusting its contact pressure with the second metal shell. During assembly, it naturally applies sufficient force to ensure good electrical contact and grounding effect without requiring precise manual adjustment, while its elasticity ensures it doesn't create excessive resistance to assembly.
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
This design achieves a stable grounding effect, ensuring reliable high-frequency transmission by allowing the latch member to maintain elasticity and maintain effective contact with the second metal shell, while reducing production costs and simplifying the manufacturing process.
Implementation Method 1
The latch member has at least one backward elastic arm which partially protrudes out of the insulating body... The elastic arm protrudes backward out of the first metal shell. The elastic arm elastically urges against the second metal shell.

AI summary
A cable connector assembly includes an electric connector having an insulating body, a first terminal group, a second terminal group, a latch member, and a first metal shell; and a second metal shell partially wrapping the periphery of a first metal shell. The first and second terminal groups have first and second ground terminals. The latch member is arranged in the insulating body and located between the first and second terminal groups. The latch member has a backward elastic arm partially protruding out of the insulating body. Both the first and second ground terminals are in electric contact with the latch member. The second metal shell has a cable-clamping portion for fixing a cable. The elastic arm elastically urges against the second metal shell.
