Crimp Terminal Transition Structure for Wire Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting terminals fail to effectively reduce the transmission of vibration to the crimped portion of a core wire, particularly in applications where a single-core wire with a small diameter is used, due to the direct contact and abrupt shape changes between the wire barrel and insulation barrel sections.
Innovation Solution
A connecting terminal design featuring a transition section with protrusions that connect the wire barrel and insulation barrel sections, providing a gradual shape change and increased points of contact to absorb vibration, thereby reducing the transmission of vibration to the crimped core wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wire barrel section and insulation barrel section are directly connected with an abrupt shape change, then the device complexity is reduced and manufacturing is easier, but the vibration transmission to the crimped core wire increases
Solution Approach 1:
The patent introduces a transition section as an intermediary element between the wire barrel section and insulation barrel section. This transition section features a gradual shape change and includes protrusions that contact the wire, serving as a mediator to reduce vibration transmission while maintaining structural integrity and electrical connectivity.
Solution Approach 2:
The connecting terminal is segmented into distinct functional sections: the wire barrel section for crimping the core wire, the transition section with gradual shape change and protrusions for vibration reduction, and the insulation barrel section for insulating the coating portion. This segmentation allows each section to optimize its specific function while reducing overall vibration transmission.
2Object-affected harmful factors
If a transition section with protrusions is added to connect the wire barrel and insulation barrel sections, then the vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
The transition section incorporates protrusions at specific locations that contact the wire, creating localized points of vibration absorption. The gradual shape change is concentrated in the transition section rather than the entire terminal, applying complexity only where needed to solve the vibration problem while maintaining simplicity in other areas.

AI summary
A connecting terminal includes a wire barrel section, an insulation barrel section, and a transition section. The wire barrel section can be crimped to a core wire exposed from a coating portion of a wire that includes the core wire and the coating portion coating the core wire. The insulation barrel section can be crimped to the coating portion. The transition section connects the wire barrel section and the insulation barrel section to each other. The transition section includes at least one protrusion on a face that opposes the wire when the wire is crimped by the wire barrel section and the insulation barrel section.
