Clamping Plug Assembly for Fast RJ45 Cable Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug assemblies for preassembled cable plugs, such as RJ45 cables, are not designed for rapid and frequent detachment of the cable plug, leading to loose components and compatibility issues with different types of cable plugs.
Innovation Solution
A plug assembly design that includes a clamping part with a radially compressible tapered section and a clamping sleeve, allowing for a threaded connection that provides a secure clamp on the cable, along with a latching arrangement that enables easy detachment and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specially designed plug assembly with threaded connection and clamping part is used to protect cable plugs, then mechanical robustness and resistance to environmental influences are improved, but the ability to rapidly and frequently detach the cable plug is reduced
Solution Approach 1:
The plug assembly is divided into separable components: a housing with threaded connection for robust attachment, and a clamping part that can be quickly released. This segmentation allows the system to maintain both strong fixation during use and rapid detachment when needed, resolving the contradiction between mechanical robustness and ease of operation.
Solution Approach 2:
The clamping part incorporates a latching mechanism that transitions between locked and unlocked states. This dynamic feature enables the connection to be secure during operation (providing mechanical robustness) while allowing rapid release when detachment is required (improving ease of operation).
2Strength
If a clamping part with radially compressible tapered section is used to clamp the cable, then the secure clamp on the cable is improved, but the device complexity increases
Solution Approach 1:
The clamping mechanism utilizes a tapered section that converts axial compression force into radial clamping force through geometric transformation. This parameter change approach provides strong cable clamping (increasing clamping force) while avoiding complex mechanical components like multiple screws or actuators (reducing device complexity).
3Ease of operation
If a latching arrangement with engagement element and stop element is used to enable easy detachment, then the ease of operation is improved, but the reliability of preventing accidental removal may be reduced
Solution Approach 1:
The latching mechanism incorporates an engagement element that must be deliberately moved to disengage from the stop element. This preliminary anti-action design ensures that accidental removal is prevented (maintaining reliability) while still allowing intentional detachment through a simple deliberate action (maintaining ease of operation).

Function Achieved in This Case
The solution allows for efficient and secure attachment and detachment of the cable plug, preventing damage from repeated use and enabling compatibility with various types of RJ45 cable plugs, including stepped and stepless types.

AI summary
The invention relates to a plug assembly (1) for use with cables with cable plugs (2), wherein the plug assembly (1) comprises a clamping part (5, 5'), a clamping sleeve (6), and a housing (4, 4'). The clamping part (5, 5') is configured to receive and position the cable plug (2) in a predetermined position at a front portion of the clamping part (5, 5') and to engage around the cable (3) in a rear portion of the clamping part (5, 5'). The clamping part (5, 5') and the clamping sleeve (6) are configured to provide a fixed connection between one another, wherein the connection is configured to generate increasing radial compression of the rear portion of the clamping part (5, 5') to clamp the cable (3). The housing (4, 4') is configured for being plugged into a socket of a complementary plug assembly and for receiving and positioning the clamping part (5, 5') in a latched position. The positioning of the clamping part (5, 5') in the latched position is provided by a latching arrangement, configured to provide a release of the latching connection between the clamping part (5, 5') and the housing (4, 4') by means of a tilting movement about a tilting axis (43) transverse to a longitudinal axis of the housing (4, 4'). The tilting movement results in an engagement element (15) of the clamping part (5, 5') being brought out of engagement with a stop element (14) of the housing (4, 4'), such that the housing (4, 4') can be pushed rearward along the cable (3), as a result of which the cable plug (2) and the clamping part (5, 5') are no longer covered by the housing (4, 4').
