Sliding Cable Clamp Structure for Compact Network Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network module cable clamps face issues with unreliable fixation, complex assembly, weakened clamping strength over time, increased length due to cover body movement, fragility, and difficulty in adjusting to cable deflection, leading to potential damage and increased part count.
Innovation Solution
A network module cable clamp design featuring a housing with pivotally connected cover bodies and a crimping cover that includes cantilevers, engaging grooves and teeth, and slide rails, allowing for easy assembly, secure clamping, and adjustable fixation without requiring additional space, using a crimping cover that slides relative to the first cover body to accommodate cable diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring-based crimping block is used to contact and fix the cable, then the cable fixation is provided, but the crimping block cannot make exact contact with the cable when the cable is deflected due to spring elasticity and compressibility
Solution Approach 1:
The patent changes the physical state of the clamping mechanism from elastic (spring-based) to rigid (lever-based), allowing the crimping block to maintain exact contact with the cable even when deflected, while the lever's rotational movement absorbs the deflection variation
Solution Approach 2:
The patent introduces a dynamic lever mechanism that can rotate around a pivot point, enabling the crimping block to adapt its position dynamically in response to cable deflection while maintaining reliable contact, unlike the static spring-based system
2Reliability
If multiple snap-in structures and W-shaped snap-in pieces are used to secure cables, then the cable fixation is improved, but the structure becomes complicated with high manufacturing costs and weakened clamping strength over time
Solution Approach 1:
The patent merges multiple separate snap-in structures into a single integrated lever mechanism with a crimping block, reducing the number of parts while maintaining fixation reliability through the lever's mechanical advantage and single-point clamping action
Solution Approach 2:
The lever mechanism serves multiple functions: it provides cable fixation, allows for assembly/disassembly operations, and maintains clamping strength over time through its rigid structure, replacing multiple specialized components with one multi-functional element
3Reliability
If two reversible cover bodies are used to clamp the cable, then the cable fixation is provided, but the overall length of the jack connector increases due to space required for cover body movement
Solution Approach 1:
The patent nests the lever mechanism within the existing cover body structure, allowing the crimping block to move within the confined space of the housing rather than requiring external space for cover body rotation, thus maintaining fixation while reducing overall length
4Reliability
If a chuck structure with locking teeth is used to secure the cable, then the cable fixation is provided, but the chuck structure is fragile and easy to break during adjustment
Solution Approach 1:
The patent extracts the fragile chuck structure and replaces it with a lever mechanism that uses a crimping block for direct cable contact, eliminating the vulnerable locking teeth and rack engagement system while maintaining fixation reliability through the lever's mechanical advantage
5Reliability
If a cable movable clamping block driven by a positioning clamp with racks and fixing bars is used, then the cable fixation is provided, but the assembly and disassembly operations are complicated and time-consuming
Solution Approach 1:
The patent segments the fixation mechanism into a simple lever that can be independently operated, allowing the lever to be pivoted open for easy cable insertion and then closed to secure the cable, eliminating the complex coordinated movement of multiple interlocked components

AI summary
A network module cable clamp includes a housing, a first cover body, a second cover body and a crimping cover. The first cover body and the second cover body are pivotally provided on the housing and cover the rear end. The first recess and the second recess of the first cover body and the second cover body form a cable entry hole corresponding to the hollow portion of the rear end. The crimping cover slides relative to the clamping piece of the first cover body. Accordingly, the distance between the crimping piece of the first cover body and the third recess can be adjusted according to the diameter of the cable, to firmly clamp the cable. In addition, the crimping cover is designed to slide relative to the first cover body, which saves space and is easy to operate.
