Connector Positioning Structure for Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector structures between male and female end connectors often face issues due to assembly tolerance discrepancies, leading to tilting, looseness, or failure to connect properly.
Innovation Solution
A positioning structure comprising a case, guiding pins, elastic parts, and a positioning member with specific distance relationships between holes and slots, allowing for precise alignment and adjustment of the male end connector with the female end connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connector structures are used without positioning adjustments, then the structure is simple, but the connecting position easily tilts, becomes loose, or fails to connect due to assembly tolerance differences
Solution Approach 1:
The positioning member with positioning holes and guiding pins are pre-configured in the case to establish accurate alignment between male and female connectors before the actual connection occurs. This preliminary positioning structure ensures that connectors align properly even when assembly tolerances vary, preventing tilting and loosening without requiring complex real-time adjustment mechanisms.
2Manufacturing precision
If positioning adjustments are added to eliminate assembly tolerance issues, then connection stability improves, but the device complexity increases
Solution Approach 1:
The positioning member acts as an intermediary element between the case and the connectors. It includes positioning holes that receive guiding pins from the case, creating a precise intermediary positioning interface. This mediator structure translates the case's positioning features into accurate connector alignment without requiring direct complex interactions between the case and connectors, thereby achieving high precision with relatively simple structures.
3Measurement precision
If rigid fixed positioning is used, then positioning precision is high, but adaptability to different assembly tolerances is reduced
Solution Approach 1:
The positioning structure incorporates elastic parts that provide dynamic adjustment capability. These elastic components allow the positioning member to adapt its position slightly within the positioning holes, accommodating variations in assembly tolerances while maintaining accurate connector alignment. This dynamic feature enables the system to handle different tolerance levels without sacrificing positioning precision, unlike rigid fixed positioning structures.

Function Achieved in This Case
Ensures smooth and accurate connection by eliminating displacement deviations through controlled movement and alignment, preventing tilting and ensuring stable positioning.
Implementation Method 1
at least one elastic part is arranged in the housing and acts on the male end connector with elastic force to push the male end connector toward the female end connector

AI summary
A positioning structure is applied to a male end connector and a female end connector. The female end connector has an inserting slot and two guiding slots. The positioning structure has a case, two guiding pins, two elastic parts, and a positioning member. The two guiding pins are connected to the case. The male end connector is located between the two guiding pins. The elastic parts are connected to the case and to the male end connector. The positioning member has a first positioning hole and two second positioning holes. The first positioning hole is used for the male end connector passing through to enter the inserting slot. The second positioning holes are used for the guiding pin passing through to enter the guiding slot.
