Multi-Wire Connector Retainer With Resilient Pressing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector designs that incorporate multiple wires in a single housing require a corresponding number of collets and retainers, leading to an increase in the overall number of components, which complicates the assembly and increases the size of the connector.
Innovation Solution
A connector design featuring a housing with multiple wires, a retainer, and supporting members where the retainer includes through holes and holding portions with resilient pieces that can deform to securely hold the wires, reducing the need for multiple collets and retainers by using a single retainer to manage multiple wires, thereby minimizing the component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple collets and retainers are used to hold multiple wires in a housing, then each wire can be securely held, but the number of components increases
Solution Approach 1:
Multiple separate collets and retainers are merged into a single integrated retainer structure that can hold multiple wires simultaneously. The retainer includes multiple holding portions that individually secure each wire, eliminating the need for separate collet-retainer assemblies for each wire while maintaining secure holding capability.
Solution Approach 2:
The single retainer structure performs multiple functions by incorporating multiple holding portions that can individually accommodate and secure different wires. This multi-functional design allows one component to replace what would traditionally require multiple separate components, reducing overall device complexity.
2Reliability
If multiple collets and retainers are used to hold multiple wires, then each wire is securely held, but assembly becomes more difficult
Solution Approach 1:
The assembly process is simplified by combining multiple wire-holding functions into a single retainer component. Instead of assembling multiple separate collet-retainer pairs, the integrated retainer can be installed as one unit, reducing the number of assembly steps and potential errors.
3Reliability
If multiple collets and retainers are used, then each wire can be held independently, but the connector size increases
Solution Approach 1:
The connector size is reduced by merging multiple wire-holding mechanisms into a single compact retainer structure. The integrated design allows multiple wires to be held within a smaller overall footprint compared to having separate collet-retainer assemblies spaced throughout the connector.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively suppresses the increase in the number of components, enhances wire holding stability, and facilitates easier assembly by reducing friction during the mounting process, while maintaining a compact connector size.
Implementation Method 1
each of the plurality of holding portions includes a resilient piece resiliently deformable in a second direction intersecting a first direction, the holding portion projecting in the first direction
Implementation Method 2
the supporting member presses the resilient piece against an outer peripheral surface of the wire

AI summary
The present disclosure provides a connector with which it is possible to suppress an increase in the number of components. A retainer comprises a main body part having a plurality of through-holes through which a plurality of electric wires respectively pass, and a plurality of retaining parts protruding from the main body part and respectively retaining the plurality of electric wires. Each of the plurality of retaining parts has an elastic piece elastically deformable in a second direction crossing a first direction in which the retaining parts protrude. A plurality of supporting members are respectively attached to the outer peripheral surfaces of the plurality of retaining parts. The supporting members each press the elastic piece against the outer peripheral surface of the electric wire.
