Connector Restriction Portion Prevents Detachment Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors fail to securely prevent detachment between electronic devices, even when the engagement mechanism is disengaged, leading to potential loss of electric connection.
Innovation Solution
A connector design featuring a fixation-side connector with a tubular insertion portion and a restriction portion on the opposite side of the electric wire-side connector, which restricts movement and maintains electric connection by abutting against the electric wire-side connector, ensuring the connection is maintained even when the engagement mechanism is disengaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only an engagement mechanism is provided between connectors, then the device complexity is reduced, but the reliability of preventing detachment deteriorates
Solution Approach 1:
The connector is divided into two functional parts: an engagement mechanism for secure connection and a restriction portion for limiting detachment movement. The restriction portion is further segmented into a first restriction part (protrusion) and a second restriction part (groove), each performing specific functions in preventing connector separation while maintaining electrical connection.
2Reliability
If a restriction portion is added to prevent detachment, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The restriction portion is integrated into the existing connector housing structure rather than being a separate component. The first restriction part is formed as a protrusion on the housing, and the second restriction part is formed as a groove, merging the restriction function with the structural elements already present in the connector design.
Solution Approach 2:
The restriction portion utilizes the inherent mechanical interference between the protrusion and groove features to automatically limit connector movement. When the connectors are assembled, the restriction parts engage and passively prevent excessive detachment movement without requiring additional actuation or control mechanisms.
3Reliability
If the restriction portion restricts movement significantly, then the reliability of preventing detachment is improved, but the ease of operation deteriorates
Solution Approach 1:
The restriction portion provides localized movement constraint only in the detachment direction, while allowing free movement during the insertion operation. The protrusion and groove are positioned and dimensioned to engage only when the connector reaches its proper assembled position, permitting easy insertion but preventing excessive withdrawal.

AI summary
An object of the present invention is to provide a connector that restricts a movement amount in a direction of detachment between connectors even when an engagement mechanism between the connectors is disengaged. A connector is configured to be used to electrically connect a first electronic device and a second electronic device to each other. This connector includes a fixation-side connector provided on a first electronic device side and including a tubularly formed insertion portion, an electric wire-side connector connected to the second electronic device via an electric wire and configured to be inserted in the insertion portion of the fixation-side connector, and a restriction portion provided on an opposite side of the electric wire-side connector from an insertion direction that is a direction in which the electric wire-side connector is inserted into the insertion portion outside the fixation-side connector and the electric wire-side connector. The restriction portion is configured to restrict a movement of the electric wire-side connector from the insertion portion in a direction causing the electric wire-side connector to be detached therefrom.
