Buckled Lead Sheath With Wire Pressing Rib
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lead sheaths for motors fail to provide reliable fixation of leads, resulting in loose connections and inadequate waterproof and dustproof performance, with complex structures and inconvenient installation.
Innovation Solution
A lead sheath design featuring buckled upper and lower jaws with a wire outlet hole, wire inlet hole, and a cavity, including a protruding wire pressing rib and grooves for secure fixation and sealing, along with seal glue injection and a flange-buckling ring mechanism for enhanced stability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lead sheaths are used, then the structure is simple, but the lead fixation is loose and unreliable
Solution Approach 1:
The lead sheath is divided into an upper jaw and a lower jaw that can be separated and then buckled together. This segmentation allows for simple installation while providing reliable fixation through the buckled configuration, resolving the contradiction between fixation reliability and structural simplicity.
Solution Approach 2:
The upper and lower jaws are designed to be movable relative to each other during installation, then fixed in a buckled position. This dynamic design enables easy installation followed by secure lead fixation, addressing the contradiction between reliable fixation and simple structure.
2Object-affected harmful factors
If conventional lead sheaths are used, then the structure is simple, but the waterproof and dustproof effect is insufficient
Solution Approach 1:
The lead sheath is segmented into upper and lower jaws with a defined connection interface. This segmentation enables the implementation of sealing measures at the connection point, improving waterproof and dustproof effects while maintaining relatively simple overall structure.
Solution Approach 2:
A sealing structure acts as an intermediary element between the upper and lower jaws at their connection point. This intermediary sealing component enhances the waterproof and dustproof protection without significantly increasing the overall structural complexity.
3Ease of operation
If conventional lead sheaths are used, then the structure is simple, but the installation is inconvenient
Solution Approach 1:
The lead sheath is divided into separable upper and lower jaws that can be independently handled during installation. This segmentation makes the installation process more convenient by allowing the jaws to be positioned and then buckled together, improving ease of operation.
Solution Approach 2:
The movable design of the upper and lower jaws during installation provides dynamic flexibility, making it easier to install the lead sheath. The jaws can be moved into position and then fixed, improving installation convenience while maintaining acceptable structural complexity.
4Reliability
If the upper jaw and lower jaw are buckled together with wire pressing rib, then the lead fixation is firm and reliable, but the structure becomes more complex
Solution Approach 1:
The wire pressing rib is merged with either the upper jaw or the lower jaw as an integrated feature. This merging provides firm lead fixation while avoiding the need for separate fixation components, thus limiting the increase in structural complexity.
Solution Approach 2:
The upper jaw or lower jaw serves multiple functions: it provides structural support and simultaneously incorporates the wire pressing rib function through the integrated design. This multi-functionality achieves reliable lead fixation without proportionally increasing structural complexity.

AI summary
A lead sheath, including an upper jaw, and a lower jaw, the upper jaw and the lower jaw are buckled with each other. A wire outlet hole is formed at the outside of the connection between the upper jaw and the lower jaw. A wire inlet hole is formed at the inside of the connection between the upper jaw and the lower jaw. A cavity is formed between the wire outlet hole and the wire inlet hole. A protruding wire pressing rib is disposed on one of the upper jaw or the lower jaw, and the wire pressing rib extends into the cavity.
