Connector Assembly Using Axial Bolt Separation to Suppress Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies face difficulties in connecting and separating the connector body from the mating connector due to the generation of twisting forces, especially when the female screw is not provided in the fixing member or when the fixing operation at the side of the shield shell is challenging.
Innovation Solution
The connector assembly incorporates a shield shell with an internally threaded hole that engages the bolt, allowing the connector body to be connected and separated along the same axis using a separation bolt, thereby minimizing twisting forces. This configuration eliminates the need for a C-ring and ensures stable fixation and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate internally threaded hole is provided for separation at a position different from the through hole of the fixing member, then the connector body can be separated from the mating connector, but a large twisting force acts on the connector during connection or separation
Solution Approach 1:
The patent merges the connection and separation functions into a single through hole by providing a closing member that can close the through hole. This allows the separation bolt to act through the same hole used for connection, eliminating the need for a separate internally threaded hole at a different position, thereby preventing twisting forces while enabling separation operation.
Solution Approach 2:
The closing member acts as an intermediary element that enables the separation bolt to apply axial force through the through hole without requiring the hole to remain open. The closing member transfers the separation force while preventing the bolt from passing through, thus achieving separation without creating twisting moments.
2Device complexity
If the female screw is not provided in the fixing member or the fixing operation at the side of the shield shell is difficult, then the connector assembly can be simplified, but the connector body cannot be separated from the mating connector when using a nut and bolt configuration
Solution Approach 1:
The closing member serves as an intermediary that enables separation functionality in a nut-and-bolt configuration. By closing the through hole with the closing member, the separation bolt can apply axial force to separate the connector body from the mating connector, thus adding separation capability without requiring a female screw in the fixing member.
Solution Approach 2:
The through hole is given multiple functions: it serves as the connection path for the bolt during assembly and as the separation path for the separation bolt when the closing member is in place. This multi-functionality allows the same structural feature to enable both connection and separation operations without additional complex components.

AI summary
A connector includes a shield shell fixable to a fixing member provided with a mating connector by a stud bolt, and a connector body held inside the shield shell and connectable to the mating connector by an axial force of the stud bolt. The shield shell includes an internally threaded hole threadably engageable with the stud bolt and is fixable to the fixing member by threadably engaging a nut with the stud bolt threadably engaged with the internally threaded hole and passed through a through hole of the fixing member. The connector body is separable from the mating connector by being relatively moved in a separation direction with respect to the mating connector by an axial force of a separation bolt threadably engaged with the internally threaded hole with the stud bolt and the nut removed and with the through hole closed by a closing member.
