Miniaturized Connector Tab Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized connectors face issues with the tab of the male internal conductor piercing the tapered surface of the female-side dielectric body, preventing reliable connection between the male and female internal conductors.
Innovation Solution
The connector design includes a male-side dielectric body with a holding member and a slide member that positions the tab relative to the female-side dielectric body using positioning portions with protruding and recessed shapes, allowing the tab to connect to the female internal conductor without interference, and a hood portion to protect the positioning portion from foreign matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tapered surface is formed in the female-side dielectric body to guide the tab, then the tab insertion is facilitated, but the tab may pierce the tapered surface causing connection failure
Solution Approach 1:
A male-side positioning portion is introduced as an intermediary element between the tab and the female-side dielectric body. This positioning portion, formed on the male-side dielectric body, guides the tab into the female-side dielectric body without the tab directly contacting the tapered surface, thereby preventing piercing while maintaining guidance functionality
Solution Approach 2:
The male-side positioning portion is designed to preliminarily guide and position the tab before it reaches the tapered surface area. By establishing the correct insertion path in advance, the tab is prevented from piercing the tapered surface during the insertion process
2Volume of moving object
If the connector is miniaturized to reduce size, then the connector compactness is improved, but the tab becomes more prone to piercing the tapered surface
Solution Approach 1:
The male-side positioning portion serves as a mediator that enables reliable tab insertion in miniaturized connectors. In compact designs where the tab has an elongated pointed shape, this positioning portion ensures proper guidance without direct contact between the tab and tapered surface, preventing piercing despite the reduced connector size
3Reliability
If the tab is positioned ahead to connect with the female internal conductor, then the connection is achieved, but the tab may interfere with the female-side dielectric body
Solution Approach 1:
The male-side positioning portion acts as an intermediary that controls the tab's insertion path. It allows the tab to reach the female internal conductor for reliable connection while preventing the tab from interfering with the female-side dielectric body by maintaining proper spatial separation through precise positioning

AI summary
A male internal conductor and a female internal conductor are reliably connected. When female-side and male-side dielectric bodies (16, 41) approach each other in an opposing positional relationship, a tab (32) of a male internal conductor (30) is inserted into a female-side dielectric body (41) and connected to a female internal conductor (42). The female-side dielectric body (41) has an opposing surface (41S) facing the male-side dielectric body (16) and formed with a female-side positioning portion (47). The male-side dielectric body (16) has an opposing surface (22S) facing the female-side dielectric body (41) and formed with a male-side positioning portion (25) which is disposed ahead of the tab (32) and which can be fitted with the female-side positioning portion (47) in a state where the tab (32) is not in contact with the female-side dielectric body (41).
