Closing Body Holding Structure for Electric Wire Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric wires with connectors fail to maintain the configuration of the closing body coupled to the connector housing due to external forces applied to the protecting member or the wire covered with it.
Innovation Solution
A closing-body holding structure that includes a connector housing with an opening portion, a closing body with an electric wire insertion hole, and a tubular protecting member, where the closing body has a housing chamber for one end of the protecting member and an inserted portion that locks the end surface of the protecting member, preventing relative displacement and maintaining the configuration of the closing body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the closing body is coupled to the opening portion of the connector housing, then the electric wire can be protected and organized, but the configuration of the closing body cannot be maintained as intended when external force is applied
Solution Approach 1:
The closing body is divided into two separate half members that can be assembled together. This segmentation allows each half member to independently engage with corresponding grooves on the corrugated tube, distributing the external force across multiple engagement points and maintaining the overall configuration stability.
Solution Approach 2:
The half members are nested together to form the complete closing body, with each half member containing grooves that receive the corrugated tube. This nested structure creates a layered engagement system where the corrugated tube is held by grooves on each half member, which are in turn held together by the coupling mechanism, providing multi-level force distribution.
2Reliability
If the closing body uses an assembly of two half members with locking portions, then the corrugated tube can be held, but the configuration may not be maintained under external force
Solution Approach 1:
The coupling mechanism merges the two half members into a unified closing body structure. The coupling protrusion and coupling groove engage to combine the separate half members, creating a structurally integrated assembly that maintains its configuration under external force while still allowing for assembly and disassembly.
Solution Approach 2:
The grooves are pre-formed on the corrugated tube and the coupling features are pre-formed on the half members before assembly. This preliminary preparation of engagement features ensures that when the half members are assembled and coupled together, the configuration is immediately established and maintained without requiring additional adjustment or force application during operation.

AI summary
An electric wire with a connector includes: an opening portion that is provided to a connector housing, and that allows an electric wire to be pulled out of the connector housing; a closing body that has an electric wire insertion hole for inserting and passing the electric wire pulled out of a wire outlet of the opening portion, and that closes the wire outlet by being attached to the opening portion; and a protecting member that is tubular and into and through which the electric wire pulled out of the wire outlet via the electric wire insertion hole is inserted and passed. The closing body includes: a housing chamber that houses one end of the protecting member; and an inserted portion that includes the housing chamber and that is inserted into the opening portion.
