Connector With Closing Portion For Secure Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for flexible cables or boards with multiple conductors face challenges in securely holding the conductive members, leading to potential disconnection, especially under harsh conditions like vibrations.
Innovation Solution
A connector design featuring a conductive member attaching portion with an insertion hole and a fitting hole, along with an engaged portion that closes the insertion hole, ensuring the conductive member is securely engaged and prevented from disconnection, while also incorporating a bending restriction mechanism to prevent the conductive member from bending and facilitate easier connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the conductive member is held by engagement between projections and concaved grooves, then the connector structure is simple, but the conductive member can come off and is not firmly held
Solution Approach 1:
The conductive member attaching portion is inserted into the holder portion, with the closing portion nesting within the insertion hole to close it. The engaging portion of the conductive member nests within the engaged portion of the holder portion, creating a nested structure that firmly secures the conductive member while maintaining simplicity.
Solution Approach 2:
The closing portion is designed to close the insertion hole after the conductive member attaching portion is inserted, preventing the conductive member from coming off. The engaging portion is pre-configured to engage with the holder portion, ensuring firm retention before final assembly completion.
2Ease of operation
If the conductive member is allowed to bend for easy insertion, then ease of operation improves, but electrical contact failures may occur
Solution Approach 1:
The bending restriction portion is pre-configured to restrict bending of the conductive member after insertion. The engaging portion is designed to engage with the holder portion in a specific orientation, preventing incorrect insertion or bending that could cause electrical contact failures.
Solution Approach 2:
The bending restriction portion applies localized constraint to the conductive member at a specific location, allowing bending only in the insertion direction while preventing bending in other directions that could cause electrical contact failures.

AI summary
A connector has a conductive member attaching portion to which an end portion of a conductive member is to be attached, and a holder portion provided with an insertion hole into which the conductive member is inserted, and a fitting hole into which the conductive member attaching portion is fitted, the fitting hole being in communication with the insertion hole, the holder portion being configured to hold the conductive member attaching portion. The holder portion is provided with engaged portions with which engaging portions, which are provided at respective ends of the conductive member in the width direction, engage. The conductive member attaching portion is provided with a closing portion configured to close a part of the insertion hole. When the conductive member attaching portion has been fitted into the holder portion, the closing portion closes a part of the insertion hole with the engaging portions engaged with the engaged portions.
