Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof lamps face difficulties in assembly due to complex structures and cable entanglement issues, with multiple components and inappropriate designs making the mounting process cumbersome and prone to errors, especially when dealing with waterproofing and dustproofing requirements.
Innovation Solution
A column-type cable entry assembly that includes a first connecting member, a positioning member (explosion-proof cable gland), and a second connecting member, which allows for secure cable passage and locking, preventing rotation and entanglement, and simplifies the assembly process by using positioning holes and threads for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple gaskets and components are used to achieve waterproofing and dustproofing performance, then safety performance is improved, but device complexity increases and assembly difficulty increases
Solution Approach 1:
The patent combines multiple gaskets and sealing components into an integrated sealing structure within the connecting assembly. The first connecting member and second connecting member are merged with built-in sealing features, eliminating the need for separate gasket components while maintaining waterproofing and dustproofing performance.
Solution Approach 2:
The connecting assembly serves multiple functions simultaneously: it provides mechanical connection between the mounting cover and lamp rod, ensures waterproofing and dustproofing through integrated sealing, and enables easy assembly/disassembly through the column-type design. This multi-functionality reduces the need for separate specialized components.
2Reliability
If multiple gaskets and components are used to achieve waterproofing and dustproofing performance, then safety performance is improved, but ease of operation deteriorates
Solution Approach 1:
The connecting assembly is segmented into distinct modular components: the first connecting member attached to the mounting cover, the second connecting member for the lamp rod, and the column-type body. This segmentation allows each component to be independently assembled and replaced, simplifying the overall assembly process while maintaining sealing integrity.
Solution Approach 2:
The connecting assembly incorporates dynamic features that enable easy assembly and disassembly. The column-type structure with positioning holes and threading allows for quick attachment and detachment of the lamp rod, making maintenance operations straightforward while the integrated sealing ensures dustproofing performance is maintained throughout the dynamic assembly process.
3Reliability
If the connecting member is mounted in the connecting end of the mounting cover, then connection is achieved, but operation difficulty increases due to limited access
Solution Approach 1:
The first connecting member is nested within or integrated with the mounting cover structure, while the second connecting member extends outward to receive the lamp rod. This nested arrangement provides stable connection between components while maintaining external accessibility for assembly and maintenance operations.
Solution Approach 2:
The column-type connecting assembly acts as an intermediary between the mounting cover and the lamp rod. It provides a stable, threaded connection interface that ensures reliable mounting while its external column structure allows tools to access and operate on the connection from outside the housing, facilitating easy maintenance.
4Reliability
If conventional connecting structures are used, then connection is achieved, but cable entanglement occurs during mounting and removal
Solution Approach 1:
The cable passage is pre-configured within the column-type connecting assembly before final assembly. The cable can be routed through the hollow interior of the connecting members in advance, and the structure is designed to maintain cable positioning during assembly and disassembly operations, preventing entanglement while ensuring strong mechanical connections.

AI summary
The present invention relates to the technical field of lamp lighting, in particular to a column-type cable entry assembly for an explosion-proof lamp. The column-type cable entry assembly includes: a first connecting member having one end joined to a cover; a positioning member being joined to the first connecting member, not locking a cable during joining of the first connecting member to the cover, and locking and positioning the cable after the first connecting member is joined to the cover, so as to prevent the cable from rotating during joining of the positioning member to the first connecting member and during the joining of the first connecting member to the cover, and an end of the positioning member not joined to the first connecting member exposing part of the first connecting member; and a second connecting member connected to the other end of the first connecting member so as to cause the positioning member to be sleeved therein and expose the first connecting member. The cable entry assembly has an appropriate structure and arrangement, and therefore does not need a plurality of additional components for structural sealing, thereby reducing costs and simplifying mounting steps. During assembly, a cable no longer needs to rotate together with components attached thereto, thereby solving the technical problem in the prior art in which a long cable is prone to entanglement.
