PCB Fixing Member With Lug-Guiding Portion For Insertion Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing members for electronic components on printed circuit boards face challenges with large inclination angles, causing lug portions to misalign and making insertion difficult, leading to increased complexity and time in mounting operations.
Innovation Solution
The introduction of a lug-guiding portion on the fixing member's arm portions, which extends from the tip end and guides lug portions into the insertion opening, even at large inclination angles, allowing for easier insertion and reducing interference between lug-guiding portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the male connector portion is inserted with a large inclination angle, then the mounting operation becomes difficult and lug portions may not be guided to the insertion opening, but adding guiding structures increases device complexity
Solution Approach 1:
The lug-guiding portion is formed in advance as an integrated structure with the lug portion, creating a pre-configured guiding path that automatically guides the lug portion into the insertion opening during insertion, eliminating the need for separate guiding mechanisms
Solution Approach 2:
The connector portion is divided into functional segments: the lug portion for engagement and the lug-guiding portion for guidance. This segmentation allows each part to perform its specific function independently while maintaining overall structural simplicity
2Adaptability or versatility
If the lug portions are designed without guiding features, then the structure remains simple, but the acceptable inclination angle range is limited and insertion becomes difficult
Solution Approach 1:
The lug-guiding portion extends in a direction toward the other lug portion, creating a three-dimensional guiding path that accommodates various inclination angles. This dimensional extension allows the connector to be inserted successfully even when the inclination angle is large, thereby broadening the acceptable inclination angle range
3Ease of operation
If multiple lug-guiding portions are added to guide all lug portions, then insertion guidance improves, but interference between lug-guiding portions may occur and device complexity increases
Solution Approach 1:
The lug-guiding portion acts as an intermediary element between the lug portion and the insertion opening. It provides a smooth transition path that guides the lug portion into the opening without requiring direct contact or complex alignment mechanisms, thereby reducing the risk of interference

AI summary
A fixing member of the present invention can be mounted to a fixed member that is fixed to a printed circuit board, and is used for fixing the fixed member to the printed circuit board, the fixing member including: a male connector portion inserted into an insertion opening formed in the printed circuit board; a plurality of arm portions provided at the male connector portion; lug portions provided at each tip end side of the arm portions and engaged with an opening edge of the insertion opening; and a lug-guiding portion extending out from a tip end portion of at least one lug portion to guide the lug portion to the insertion opening when the lug-guiding portion comes in contact with the opening edge and is further pressed.
