Split Electric Wire Holder Locking Against Longitudinal Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric wire connectors are prone to displacement of split bodies relative to each other in the longitudinal direction due to local loads, leading to improper attachment to the connector housing.
Innovation Solution
An electric wire holder with C-shaped insertion portions and lock mechanisms that secure the split bodies immovably in the longitudinal direction, ensuring stable attachment to the connector housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the conventional connector with L-shaped lock protrusion and inverted L-shaped lock recessed portion is used, then the structure is simple, but the split bodies may be displaced relative to each other in the longitudinal direction when local load is applied
Solution Approach 1:
The lock portion is divided into two functional elements: a lock protrusion that engages with the lock recessed portion, and additional locking features that distribute the load across multiple contact points. This segmentation prevents concentration of stress at a single point while maintaining structural simplicity.
Solution Approach 2:
The lock portion extends in multiple directions rather than solely in the longitudinal direction. By adding lateral locking features that engage with corresponding recesses in the connector housing, the design creates a multi-dimensional locking system that resists displacement in both longitudinal and lateral directions.
2Ease of operation
If the lock portion only engages in the longitudinal direction, then the attachment process is simple, but the ease of attachment to the connector housing is reduced when local load is applied
Solution Approach 1:
The lock protrusion and lock recessed portion are pre-configured to engage automatically when the electric wire holder is inserted into the connector housing. The geometry of these features ensures that proper engagement occurs naturally during the attachment process without requiring additional manual steps, while still providing reliable locking under local loads.
3Strength
If the C-shaped first and second insertion portions are used to sandwich the electric wire, then the wire support is improved, but the lock mechanism must prevent displacement in the longitudinal direction
Solution Approach 1:
The locking function is merged with the existing C-shaped insertion portions. The lock protrusion and lock recessed portion are integrated into the same structural elements that sandwich the electric wire, rather than being separate components. This merging provides both wire support and longitudinal displacement prevention without significantly increasing overall device complexity.

AI summary
An electric wire holder is configured to be attached to the end portion of a tubular-shaped connector housing through which a plurality of electric wires are inserted to support the plurality of electric wires and includes a first insertion portion in a C shape including two member including a plurality of tubular-shaped electric wire insertion portions through which the plurality of electric wires is inserted and capable of sandwiching the plurality of electric wires, each of the plurality of electric wire insertion portions being provided only on a member of the two members, a second insertion portion in a C shape provided on the other member of the two members, and a lock portion configured to combine the first insertion portion and the second insertion portion, wherein the lock portion includes a lock piece protruding from one of the first insertion portion and the second insertion portion to another thereof and a lock receiving-portion provided on the other of the first insertion portion and the second insertion portion to lock the lock piece immovably in a direction in which the electric wires extend.
