Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of stainless steel metallic housings in electrical connectors, combined with increased mold size and waste due to side tabs, leads to higher production costs and resource inefficiency.
Innovation Solution
An electrical connector design featuring a low-cost mount plate with hook-shaped ribs to secure the mount plate to the metallic housing, replacing the need for side tabs and reducing mold size and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side tabs are extended from the metallic housing to fix the electrical connector to the case, then the electrical connector can be securely fixed, but the mold size increases and production cost increases significantly
Solution Approach 1:
The invention divides the fixing structure into two separate components: the metallic housing and the mount plate. The mount plate is a separate element that attaches to the metallic housing via hook-shaped ribs, and then the mount plate is fixed to the case. This segmentation allows the metallic housing to maintain its original size without side tabs, keeping mold costs low, while the mount plate provides the necessary fixing functionality.
Solution Approach 2:
The mount plate serves as an intermediary component between the metallic housing and the case. Instead of extending side tabs directly from the expensive metallic housing, the mount plate acts as a mediator that provides the fixing function. This intermediary approach allows the metallic housing to remain compact while achieving secure fixation through the mount plate.
2Reliability
If side tabs are extended from the metallic housing, then the electrical connector can be fixed to the case, but more scraps are generated and resource waste increases
Solution Approach 1:
By segmenting the fixing function into a separate mount plate component, the metallic housing does not require material extension in the form of side tabs. This reduces material waste from the metallic housing production while the mount plate (made from potentially recycled or lower-grade materials) provides the necessary fixing structure.
Solution Approach 2:
The invention changes the material parameter of the fixing component. Instead of using the same expensive metallic material for both the housing and side tabs, the mount plate is made from different materials (iron or plastic) that are more cost-effective and generate less waste. This parameter change in material selection reduces overall resource waste and production cost.
3Object-affected harmful factors
If stainless steel metallic housing is used, then electromagnetic interference protection is provided, but production cost increases significantly
Solution Approach 1:
The invention applies local quality by providing electromagnetic interference protection only where needed - in the metallic housing that encloses the electrical connector components. The mount plate, which is outside the housing, is made from lower-cost materials (iron or plastic) that do not provide EMI protection but are sufficient for their mounting function. This localized approach to material quality reduces overall cost while maintaining necessary EMI protection.
Solution Approach 2:
The invention uses composite material strategy by combining stainless steel metallic housing (for EMI protection) with low-cost mount plate materials (iron or plastic). This composite approach allows each component to be made from the most cost-effective material for its specific function, reducing overall production cost while maintaining electromagnetic interference protection through the metallic housing portion.

AI summary
An electrical connector includes a mount plate and a metallic housing. The metallic housing includes a metallic frame and at least one hook-shaped rib which extend from the metallic frame and are used to hold the mount plate. The mount plate is made of low-cost material to replace expensive side tab extending from the metallic housing. Thus, size of mould for the metallic housing is decreased, scraps is fewer and cost is lowered.
