Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attaching a coaxial cable connector is a time-consuming and fiddly process, often resulting in poor electrical connections and insecure mechanical attachments due to the complexity of stripping, folding, and aligning components.
Innovation Solution
A connector plug with a piercing element and radially adjustable gripping legs, along with a spacer element and cutter tool, simplifies the attachment process by ensuring secure electrical and mechanical connections through a piercing mechanism and easy cable preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional coaxial connector plug is used, then the connection provides electrical connectivity, but the attachment process is time-consuming and complex
Solution Approach 1:
The connector plug is divided into distinct functional components: a body member with an outer connector element, a separate inner element for the inner conductor, and a piercing element. This segmentation allows each component to be optimized independently and simplifies the assembly process, reducing attachment time while maintaining connection quality.
Solution Approach 2:
The piercing element is pre-configured to pierce through the outer insulator sleeve and establish electrical connection with the outer conductor before the cable is fully assembled. This preliminary action ensures proper electrical connectivity is achieved during the attachment process itself, eliminating the need for separate connection steps and reducing overall attachment time.
2Reliability
If a traditional coaxial connector plug is used, then the connection provides electrical connectivity, but the process is fiddly and requires careful attention
Solution Approach 1:
The piercing element automatically pierces the outer insulator sleeve and establishes electrical connection with the outer conductor during the attachment process. This self-service mechanism eliminates the need for manual folding of the braided outer conductor and careful alignment, making the process much easier to perform while ensuring reliable electrical connection.
Solution Approach 2:
The piercing element combines multiple functions into a single component: it mechanically secures the outer insulator sleeve, establishes electrical connection with the outer conductor, and positions the inner element. This merging of functions into one element simplifies the attachment process by eliminating multiple separate operations that require careful attention.
3Ease of manufacture
If a traditional coaxial connector plug is used, then the connection can be made, but the mechanical attachment may not be secure
Solution Approach 1:
The piercing element features a curved or angled piercing surface that distributes mechanical stress across a broader area of the outer insulator sleeve and outer conductor. This curved geometry enhances the mechanical bond strength while maintaining simplicity of assembly, as the curvature naturally guides the assembly process and ensures proper seating.
Solution Approach 2:
The connector plug utilizes composite construction with the body member made of one material and the piercing element made of a different material optimized for piercing and electrical conduction. This composite approach allows each material to be selected for its optimal properties, resulting in both easy assembly and strong mechanical attachment.

AI summary
The connector plug (2) is designed for use with a coaxial cable (40) comprising inner and outer conductors (44, 48), an inner insulator (50) between the inner and outer conductors and an outer insulator sleeve (46). The connector plug (2) comprises a body member (4) configured for electrical connection to the outer conductor, a support element (6) configured to receive and support the inner conductor, a gripper element (10) for gripping the cable and a retaining cap (12) that is configured to adjust the gripper element between a gripping configuration and a non-gripping configuration. The gripper element (10) includes at least one piercing element (32) that is configured to pierce the outer insulator sleeve (46) and establish an electrical connection between the body member (4) and the outer conductor (48) when the gripper element (10) is in a gripping configuration.
