Movable Housing Connector Guide for Misaligned Pin Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with movable housings struggle to facilitate easy and accurate insertion of pin-shaped partner connection members arranged side by side, often resulting in misalignment and increased complexity and size of the connector structure.
Innovation Solution
The electrical connector incorporates a guide portion with first and second inclined surfaces in the movable housing, allowing pin-shaped partner connection members to be guided and inserted into corresponding insertion holes, even when inserted at deviated positions, thereby simplifying the insertion process and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable housing is provided to absorb positional deviation and vibration, then reliability is improved, but device complexity increases
Solution Approach 1:
The connector is divided into a fixed housing and a movable housing that can displace relative to each other. The movable housing is further segmented to include guide portions with inclined surfaces that independently guide each pin-shaped partner connection member. This segmentation allows the movable housing to absorb positional deviation and vibration while maintaining a relatively simple overall structure.
Solution Approach 2:
The movable housing is designed to be dynamically displaceable relative to the fixed housing, allowing it to absorb positional deviation and vibration during insertion and operation. The guide portions with inclined surfaces provide dynamic guidance that adapts to misalignment, enabling the structure to handle positional variations without requiring complex adjustment mechanisms.
2Ease of operation
If guide mechanisms are added to facilitate insertion of pin-shaped partner connection members, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The guide portions are equipped with inclined surfaces that provide a tapered guidance path for the pin-shaped partner connection members. This curved or angled surface design naturally guides the pins into the correct position during insertion, eliminating the need for complex alignment mechanisms while significantly improving ease of operation.
Solution Approach 2:
The inclined surfaces on the guide portions enable the pin-shaped partner connection members to self-align and self-guide during insertion. The geometry of the inclined surfaces automatically corrects minor misalignments without requiring external guidance mechanisms, allowing the connector to facilitate easy insertion through its own structural features.
3Device complexity
If the connector structure is simplified to reduce size, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The guide portions with inclined surfaces perform preliminary alignment of the pin-shaped partner connection members before they reach the insertion holes. This preliminary guidance action ensures that even if the insertion holes are not perfectly positioned, the pins are guided into correct alignment during the insertion process, reducing the stringency of manufacturing precision requirements for the insertion holes themselves.
Solution Approach 2:
The inclined surfaces change the geometric parameters of the insertion path, providing a gradual transition from misaligned to aligned positions. This parameter change in the guidance geometry allows the system to tolerate larger variations in insertion hole positioning while still achieving proper connection, effectively reducing the required manufacturing precision.

AI summary
An electrical connector includes a fixed housing, a movable housing, and a plurality of terminals. The movable housing includes a guide portion that is provided with an opening and receives a plurality of partner connection members, and a plurality of insertion holes that are arranged side by side inside the guide portion and respectively receive insertion of the partner connection members. An inner wall of the guide portion includes first inclined surfaces that are respectively provided at two end sides in the width direction and widen in a tapered manner while extending in the height direction and outward in the width direction. Second inclined surfaces, which are provided between each pair of the insertion holes adjacent to each other in the width direction, extend in a tapered manner toward the entrances of the insertion holes. The first inclined surfaces have a larger dimension in the width direction and dimension in the height direction than the second inclined surfaces.
