Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors have numerous components, a complex assembly process, large size, high cost, and risks of electrical shorts due to braided components entering screw holes, posing challenges in high-altitude outdoor environments.
Innovation Solution
A cable connector design featuring an outer shell, insulating housing, inner conductive body, and a movable insulating ring that shields or exposes fastener access points, preventing braided layer debris from contacting the fastener and ensuring safe, efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable connector structures are used, then electrical connection is achieved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent combines multiple components into integrated structures. The insulating housing integrates the insulating body with the fastening structure, eliminating separate insulating components. The outer shell integrates the protective housing with the fastener access mechanism, reducing the total component count while maintaining electrical connection reliability.
Solution Approach 2:
The insulating housing serves multiple functions simultaneously: it provides electrical insulation between conductors, houses the fastening mechanism, and structurally supports the connector assembly. The outer shell provides both protective enclosure and controlled access to the fastener, reducing the need for separate protective and access components.
2Reliability
If conventional cable connector structures are used, then electrical connection is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The insulating housing is pre-formed with integrated fastening features and alignment structures, allowing components to be assembled in a predetermined sequence without complex alignment procedures. The outer shell is pre-configured with the fastener access mechanism, enabling rapid assembly during field operations.
3Reliability
If screw fasteners are used to secure the inner conductive body, then electrical connection is secured, but electrical short circuit risk increases due to braided component contact
Solution Approach 1:
The insulating housing acts as an intermediary barrier between the conductive fastener and the braided shielding component. It provides electrical isolation while allowing the fastener to securely hold the inner conductive body, eliminating the short circuit risk without compromising connection stability.
4Ease of operation
If the fastener is exposed for assembly operations, then assembly accessibility is improved, but electrical isolation is compromised when the fastener contacts the metal outer shell
Solution Approach 1:
The outer shell incorporates a movable or removable section that dynamically controls access to the fastener. During assembly operations, the shell can be opened or shifted to expose the fastener for tool access. After assembly, the shell returns to its closed position, restoring electrical isolation between the fastener and external environment.

AI summary
A cable connector includes an outer shell, an outer electrical conductor mounted within the outer shell and defining a first through hole, an insulating housing disposed inside the outer electrical conductor and defining a second through hole, an inner electrical conductor disposed inside the insulating housing and defining an insertion cavity and a connection hole communicating with the insertion cavity, a fastener mounted at least partially in the connection hole and operable to fasten a center conductor of the cable inserted into the insertion cavity, and an insulating ring fitted over the outer circumferential surface of the electrical conductor. The insulating ring is movable between a shielding position in which the first through hole is covered and a non-shielding position in which the first through hole is uncovered to allow the fastener to be exposed from the first and second through holes aligned with each other.
