Sliding Cable Sealing Box for Waterproof Wiring Without Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable wiring methods using waterproof terminals are cumbersome, require large mounting spaces, and involve high costs due to the need for multiple terminals and complex operations, especially with thicker cables, which also pose a risk of water leakage and inconvenient maintenance.
Innovation Solution
A threading sealing box with a box body and threading assembly, featuring a slidably arranged threading plate assembly and threading body that circumferentially seals cables, eliminating the need for waterproof terminals and allowing easy cable removal without lifting the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof terminals are used for cable wiring, then cable protection is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent extracts and eliminates the waterproof terminal component from the system, replacing it with an integrated sealing structure directly formed on the box body. The threading plate with integrated sealing body removes the need for separate waterproof terminals, tightening nuts, and locking mechanisms, thereby simplifying the overall device structure while maintaining cable protection functionality.
Solution Approach 2:
The patent merges the sealing function and cable fixation function into a single integrated threading plate structure. The sealing body is directly formed on the threading plate, combining what were previously separate components (waterproof terminal, sealing element, and mounting bracket) into one unified component that performs multiple functions simultaneously.
2Reliability
If waterproof terminals are used for cable wiring, then cable protection is improved, but mounting time and operation time increase
Solution Approach 1:
The threading plate is pre-assembled with the sealing body integrated on it before installation. The sealing body is prepared in advance on the threading plate, so that during installation, no additional steps for assembling sealing elements or tightening nuts are required. The cable is simply inserted through the pre-prepared threading plate and sealing body structure.
Solution Approach 2:
The patent segments the mounting process into a single simple insertion action rather than multiple complex steps. By integrating the sealing function into the threading plate itself, the mounting process is segmented into just inserting the cable through the threading plate, eliminating the need for separate tightening and locking operations.
3Reliability
If multiple waterproof terminals are mounted for multiple cables, then cable protection is improved, but mounting space increases
Solution Approach 1:
The threading plate is designed as a universal component that can accommodate multiple cables simultaneously through multiple threading holes. Each threading hole has an integrated sealing body, allowing the single threading plate to serve as both structural support and sealing element for multiple cables, replacing what would otherwise require multiple separate waterproof terminals.
4Reliability
If thick cables are installed with waterproof terminals, then cable protection is improved, but operation convenience deteriorates
Solution Approach 1:
The threading plate with integrated sealing body performs self-service by automatically sealing around the cable as it is inserted. The elastic sealing body deforms to match the cable diameter and automatically creates a waterproof seal without requiring external tightening tools or additional fastening operations. The structure serves itself to secure and seal the cable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
A threading sealing box includes a box body and a threading assembly, and an opening is formed in the box body, a mounting groove is formed in a side wall of the box body, the threading assembly comprises a threading plate assembly and a threading body, the threading plate assembly is slidably arranged in the mounting groove so as to slide into or slide out of the mounting groove, a penetrating hole is formed in the threading plate assembly, the threading body is arranged on the threading plate assembly, and the threading body communicates with the penetrating hole. A cable penetrating through the threading body can be circumferentially sealed by the threading body, thereby effectively reducing the water leakage risk; the cable does not need to be locked by using accessories such as a waterproof terminal, such that the operation is simple.
