Screwless Busbar Connection Module with Transverse Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional busbar connection modules require a large amount of space due to the side-by-side arrangement of clamping devices and are complex in structure, necessitating the use of screws for assembly and disassembly, which is cumbersome and time-consuming.
Innovation Solution
A screwless busbar connection module design where clamping devices are aligned one behind the other in a plane, allowing stripped cable ends to be automatically locked by a clamping spring and easily released using a tool, with a compact width and adaptable to various cable cross-sections, featuring a housing with a cover that can be opened without removal during wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clamping devices are arranged side-by-side in the longitudinal direction, then the connection module can accommodate multiple poles, but the space required increases and the structure becomes complex
Solution Approach 1:
The clamping devices are arranged one behind the other in a transverse plane rather than side-by-side in the longitudinal direction. This dimensional reconfiguration reduces the longitudinal space required while maintaining multi-pole functionality through the transverse arrangement of clamping devices within the housing.
2Reliability
If screw fastening is used for clamping devices, then secure connection is achieved, but assembly and disassembly become cumbersome and time-consuming
Solution Approach 1:
The clamping devices are designed with spring elements that automatically clamp the cable ends when inserted through through-openings. The spring mechanism self-activates upon insertion, eliminating the need for manual screw fastening and enabling quick assembly without tools while maintaining secure connection through the spring force.
Solution Approach 2:
The manual screw fastening system is replaced with an automatic spring clamping mechanism. The spring element provides the clamping force automatically when the cable is inserted, substituting the manual mechanical screw operation with an automatic elastic mechanical system that achieves secure connection faster.
3Area of stationary object
If clamping devices are arranged one behind the other in a plane, then space is reduced and assembly is simplified, but the design becomes more constrained
Solution Approach 1:
Multiple clamping devices are integrated into a single housing structure arranged in a transverse plane. The housing combines multiple clamping functions in a compact configuration, reducing overall space while managing structural constraints through unified design of the housing and partition walls that support all clamping devices in the constrained plane.
