Connector Wire Cover Protruding Pressing Surface

Solution Overview

Problem

The rear surface of conventional wire covers in connectors is difficult to press when connecting to a mating connector, making the connecting operation challenging due to its curvature along the wire bundle.

Innovation Solution

A connector design with a protruding portion that includes a pressing surface, allowing easy connection by pressing the rear surface of the protruding portion during the mating process, and a wire cover configuration with a recess to position the tie band, facilitating the connection operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wire cover rear surface is curved along the wire bundle, then the wire bundle is held securely, but the connecting operation to the mating connector becomes difficult

Engineering Contradiction:

Improvewire bundle holding stabilityVSAvoidconnecting operation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The wire cover is divided into two functional surfaces: a curved rear surface for securely holding the wire bundle, and a flat pressing surface for easy connection to the mating connector. This segmentation allows each surface to optimize its function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the wire cover are given different geometric properties: the rear surface is curved to match and secure the wire bundle shape, while the pressing surface is flat to enable easy pressing during connection. This local differentiation resolves the contradiction between secure holding and ease of operation.

AI summary

It is aimed to provide a wire cover and a connector with wire cover enabling a connecting operation to a mating connector to be easily performed. A wire cover (30) to be mounted on a rear surface of a connector body (C) connected to ends of wires (W) and configured to hold the wires (W) while bending the wires (W) in a predetermined direction includes a wire fixing portion (38) provided on a rear part to project in the predetermined direction and a protruding portion (41) provided to protrude from the wire fixing portion (38) in a direction substantially perpendicular to a connecting direction of the connector body (C) and a mating connector (50).
