Shield Shell Fastening Position Aligning Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield shells lack a configuration for aligning the fastening position of a binding member, making it difficult to securely fasten the binding member and preventing it from being removed when the shield member is pulled, leading to unreliable connections in shielded connectors.
Innovation Solution
A shield shell with a shield member mounting portion featuring an inclined portion and a restricting portion, where the fastening position aligning unit is provided on the entire circumference or multiple positions, ensuring the binding member is securely fastened and restricted from moving, with the restricting portion's height matching or exceeding the combined height of the shield and binding members, and a curved continuous portion to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shield shell uses a conventional mounting portion with outer surface formed substantially parallel to axial direction, then the structure is simple, but the binding member cannot be reliably fastened to an appropriate fastening position
Solution Approach 1:
The patent applies preliminary action by pre-forming an inclined portion on the mounting portion before the binding member is installed. This inclined portion automatically guides the binding member to the correct fastening position during installation, eliminating the need for complex alignment operations while ensuring reliable fastening. The restricting portion is also pre-formed to prevent backward movement, securing the binding member in place without requiring additional fastening steps.
Solution Approach 2:
The inclined portion acts as an intermediary element between the mounting portion and the binding member. It mediates the positioning process by providing a tapered surface that naturally guides the binding member into the correct position, transforming a complex alignment problem into a simple insertion operation. The restricting portion serves as a mediator to prevent the binding member from moving backward, ensuring it remains securely fastened.
2Device complexity
If no fastening position aligning unit is provided, then the device complexity is reduced, but the binding member may be removed when the shield member is pulled toward the open end side
Solution Approach 1:
The restricting portion is pre-formed on the mounting portion to create a physical barrier that prevents the binding member from moving backward when the shield member is pulled. This preliminary structural feature ensures connection reliability without requiring complex locking mechanisms or additional fastening steps, maintaining device simplicity while preventing binding member removal.
Solution Approach 2:
The restricting portion implements preliminary anti-action by creating a counter-force structure that opposes the pulling force applied to the shield member. When the shield member is pulled toward the open end side, the restricting portion provides a counteracting force that prevents the binding member from moving backward, thereby maintaining connection reliability through a simple geometric feature rather than a complex active restraint system.
3Ease of manufacture
If the binding member is fastened without an aligning configuration, then the manufacturing process is simpler, but it is not easy to fasten the binding member to an appropriate fastening position
Solution Approach 1:
The inclined portion is pre-formed on the mounting portion to automatically guide the binding member to the correct fastening position during installation. This preliminary geometric feature transforms a difficult alignment operation into a simple insertion process, where the tapered surface naturally directs the binding member into the proper position without requiring precise manual alignment or complex tooling.
Solution Approach 2:
The inclined portion serves as an intermediary that facilitates the fastening operation by providing a guiding surface. During installation, this intermediary feature automatically aligns the binding member with the correct position, making the fastening operation easy to perform while maintaining manufacturing simplicity. The restricting portion then acts as a mediator to secure the binding member in place, preventing any backward movement.

AI summary
A shielded connector includes a shield shell and a shield member. The shield shell includes a shield member mounting portion on which the shield member is mounted by fastening of a binding member. The shield member mounting portion includes a fastening position aligning unit on an outer surface thereof. The fastening position aligning unit includes an inclined portion and a binding member movement restricting portion. The inclined portion is inclined in a tapered shape from a base end side of the shield member mounting portion toward an open end side. The binding member movement restricting portion restricts the binding member from moving toward the open end side of the shield member mounting portion.
