Slide-Crimp Connector Housing Opening to Prevent Terminal Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crimping methods for connecting a terminal to a core wire can cause deformation of the housing and terminal body due to the application of force during the slide structure, especially when a slide portion is pressed and slid in a state where the terminal is accommodated inside a housing.
Innovation Solution
A connector design with a terminal body having a sandwiching portion and a slide portion, where the housing includes an opening exposing a part of the terminal body to the front, allowing a front pressing jig to be inserted and contact the terminal body, thereby suppressing deformation and enabling secure connection of the core wire through a slide structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slide portion is pressed and slid in a state where the terminal is accommodated inside the housing, then the core wire can be sandwiched and connected, but the housing and terminal body may be deformed by the applied force
Solution Approach 1:
The patent applies preliminary action by exposing the front end of the terminal body through an opening in the housing before the sliding operation. This allows a pressing jig to be inserted and make contact with the terminal body in advance, providing counteraction to prevent deformation when the slide portion is pressed and slid to sandwich the core wire.
2Reliability
If a slide portion is pressed and slid in a state where the terminal is accommodated inside the housing, then the core wire can be sandwiched and connected, but the terminal body may be deformed by the applied force
Solution Approach 1:
The patent applies preliminary action by exposing the front end of the terminal body through an opening in the housing before the sliding operation. This allows a pressing jig to be inserted and make contact with the terminal body in advance, providing counteraction to prevent deformation when the slide portion is pressed and slid to sandwich the core wire.
3Shape
If the terminal is fully accommodated inside the housing, then the appearance is neat and compact, but force cannot be applied to the terminal body to suppress deformation during sliding
Solution Approach 1:
The patent applies local quality by creating a localized opening in the housing that exposes only the front end of the terminal body. This allows the housing to remain compact and neat overall while providing a specific local area where the terminal body is accessible for force application during the sliding operation, preventing deformation.

AI summary
A connector 10 is provided with a terminal 12 to be connected to a core wire 13 located on an end part of a wire 11 including the core wire 13, and a housing 30 including an accommodating portion 29 for accommodating the terminal 13. The terminal 12 includes a terminal body 15 having a sandwiching portion 18 and a slide portion 16 for sandwiching the core wire 13 by the sandwiching portion 18 by being pressed and slid from behind with respect to the terminal body 15. The housing 30 includes an opening 32. The opening 32 exposes a part of a front end part of the terminal body 15 to front.
