Connector Shield Bracket Assembly for Easier EMI Shield Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector units face difficulties in adjusting the position of the electromagnetic shield member due to the challenge of fixing two plates to the electromagnetic shield member, which complicates the assembly process.
Innovation Solution
The connector unit incorporates a fixing member with overlapping first and second plates, featuring positioning holes and cutaway portions that allow for precise alignment and adjustment of the electromagnetic shield member, facilitating its secure fixation without compromising the assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two plates are used to sandwich and fix the electromagnetic shield member, then the fixing strength is improved, but the ease of positioning and adjusting the electromagnetic shield member deteriorates
Solution Approach 1:
The fixing member is divided into two separate plates (first plate and second plate) that sandwich the electromagnetic shield member. This segmentation allows the shield member to be positioned and adjusted before final fixation, as the two plates can be independently manipulated during assembly.
Solution Approach 2:
Positioning protrusions on the first plate and corresponding positioning grooves on the second plate serve as intermediary elements that guide and constrain the electromagnetic shield member during assembly. These intermediaries enable easy positioning while maintaining strong fixation once assembled.
2Reliability
If the electromagnetic shield member is securely fixed between two plates, then the reliability of the connection is improved, but the assembly complexity increases
Solution Approach 1:
The positioning protrusions and grooves are pre-formed on the fixing member plates, enabling the electromagnetic shield member to be automatically positioned correctly during assembly. This preliminary positioning action reduces assembly complexity by eliminating the need for complex alignment procedures.
Solution Approach 2:
The fixing member is segmented into two plates with complementary positioning features. This segmentation allows for simpler individual components that are easier to manufacture and assemble, while still providing reliable fixation when combined.

AI summary
An electromagnetic shield member according to one aspect of the present disclosure has an end portion fixed by being sandwiched between a bracket body serving as a first plate and a second fixing plate serving as a second plate. The bracket body has first positioning holes penetrating the bracket body in the plate thickness direction thereof. The second fixing plate has an end portion provided with first cutaway portions. Each of the first positioning holes and each of the first cutaway portions are formed such that the width of the first positioning hole and the width of the first cutaway portion are equal to each other in a first direction. Further, a part of the first positioning hole and a part of the electromagnetic shield member are positioned in the area of the first cutaway portion when viewed from the plate thickness direction of the second fixing plate.
