Door Connector Housing with Lateral Wire Exit
Solution Overview
Problem
Existing connectors for vehicle doors face challenges in minimizing the protrusion of electric wires and grommets, leading to increased costs and reduced signal transmissibility due to the need for longer wire lengths and larger connector sizes, which complicates the mounting of grommets in narrow spaces.
Innovation Solution
The design includes a housing with a terminal seating space and an electric wire seating space that opens towards the rear and side of the housing, featuring a locking rib with parallel and inclined parts to guide the electric wire and grommet, reducing the protrusion of the electric wire and grommet, and an electric wire guide cover to prevent backward protrusion, allowing for easier grommet mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric wire extends to the rear of the connector and is bent, then the wire can be connected to the terminal, but the length of the electric wire increases and cost burden increases
Solution Approach 1:
The electric wire seating space is configured to open in both the rearward direction and the lateral direction (toward the side of the housing). This multi-directional opening allows the electric wire to exit the connector in a lateral direction rather than extending rearward and bending, thereby reducing the overall wire length while maintaining connection functionality.
2Ease of operation
If the electric wire protrudes more than the rear end of the housing and is bent, then the wire can be routed, but the grommet must protrude more from the rear end of the housing, increasing the connector size
Solution Approach 1:
The electric wire seating space opens in both rearward and lateral directions, allowing the wire to exit laterally instead of protruding beyond the rear end. This reduces the protrusion requirement for the grommet and minimizes the overall connector size, enabling installation in narrow spaces between the door and vehicle body.
Solution Approach 2:
The housing is divided into distinct functional spaces: a terminal seating space for electrical connections and an electric wire seating space for wire routing. This segmentation allows independent optimization of each space, with the wire seating space specifically designed to open laterally to reduce grommet protrusion.
3Reliability
If the grommet is designed to adhere to the housing for waterproofing, then waterproofing is achieved, but the locked portion constantly protrudes to the rear of the housing
Solution Approach 1:
The electric wire seating space opens in both rearward and lateral directions, which changes the spatial relationship between the grommet and the housing rear end. This multi-directional opening configuration allows the grommet to maintain its waterproof sealing function while reducing its protrusion beyond the housing rear end, as the wire exit path is redirected laterally.

AI summary
The present disclosure relates to a housing and a connector for a door using the same. The housing forming a skeleton of a connector for a door coupled with a counter connector which is mounted in a panel includes: a terminal seating space configured to be formed by penetrating through the housing back and forth and an electric wire seating space configured to communicate with the terminal seating space to be opened to a rear of the housing, and an electric wire guide cover configured to prevent the electric wire seating space from protruding backward so as to prevent a load from being applied to a grommet in which an electric wire is coupled with the housing.
