Solution Overview
Problem
The existing contactor designs require different interfaces for various connection modes, leading to increased design, manufacturing, and management costs.
Innovation Solution
A contactor design that includes a housing with stationary contact brackets and isolation sheets, allowing for multiple connection modes without the need for separate interfaces, thereby enhancing compatibility and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different contactor interfaces are designed for different connection modes, then connection adaptability is improved, but design cost and manufacturing cost increase
Solution Approach 1:
The patent applies universality by designing a single standardized contactor interface that can accommodate multiple connection modes through the use of detachable isolation sheets. The isolation sheets can be removed or retained based on the specific connection mode, allowing the same basic interface to serve multiple functions - whether for isolated connections, non-isolated connections, or different wire configuration modes. This eliminates the need to design separate interfaces for each connection mode, thereby reducing design complexity while maintaining connection adaptability.
2Adaptability or versatility
If different contactor interfaces are designed for different connection modes, then connection adaptability is improved, but management cost increases
Solution Approach 1:
The patent reduces management cost by standardizing the contactor interface design. Instead of managing multiple different interface types, the standardized design with optional isolation sheets allows a single product model to serve multiple connection mode requirements. This simplifies inventory management, reduces the number of SKUs, and lowers management costs while maintaining the ability to adapt to different connection modes through simple configuration changes.
3Reliability
If isolation sheets are added to separate adjacent wiring terminals, then electrical isolation is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the contactor interior into isolated sections using detachable isolation sheets. These sheets can be positioned between adjacent wiring terminals to create electrical isolation when needed. The segmentation is achieved through simple, removable components rather than complex integrated structures, allowing the isolation function to be added or removed based on specific application requirements without permanently complicating the overall device structure.

AI summary
A contactor, which includes: a housing; a plurality of stationary contact brackets, fixed to the housing, wherein each of the plurality of stationary contact brackets includes a bracket body accommodated in the housing and a wiring terminal extending out of the housing and configured to be connected with an electric wire, the wiring terminal includes a sheet-shaped terminal body and a terminal hole penetrating through a thickness of the terminal body; and an isolation sheet, arranged between adjacent wiring terminals and separates the adjacent wiring terminals. The design of the contactor according to the present disclosure can meet at least four different connection modes of different customers at the same time, thus increasing the application compatibility of the contactor and reducing the design cost and management cost.
