Angled Electrical Plug Connector with Detachable Shell Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing right-angle electrical plug connectors often require a tool to assemble and have a narrow opening that makes it difficult to insert cables and access the insulating body, particularly for stranded wires, limiting connectivity and accessibility.
Innovation Solution
A tubular angled connector housing with detachably connected, channel-shaped shell parts that can be separated axially, allowing for easy cable insertion and access to the insulating body, featuring a main parting plane and optional secondary plane for radial separation, and a screw connection with guide elements for secure assembly without a separate tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable cover is provided to access the insulating body, then access to the insulating body is improved, but the device complexity increases and tool requirement worsens
Solution Approach 1:
The connector housing is segmented into two detachable shell parts (first shell part and second shell part) that can be separated from each other. This segmentation allows access to the insulating body without requiring a separate cover component, thereby improving accessibility while avoiding additional device complexity. The shell parts are designed to be separable along a parting plane, enabling direct access to the insulating body when needed.
2Manufacturing precision
If the connecting leg is designed as a single piece, then the manufacturing precision is improved, but the ease of operation deteriorates due to narrow opening
Solution Approach 1:
The connecting leg is divided into two shell parts that can be separated from each other. This segmentation creates a larger opening when the shell parts are separated, facilitating easier cable insertion and wire access. The two shell parts are designed to assemble together to form the complete connecting leg structure, maintaining manufacturing precision while improving operational ease through the separable design.
3Reliability
If a screw connection is used to attach the cover, then the reliability is improved, but the ease of operation worsens due to tool requirement
Solution Approach 1:
The two shell parts are designed with self-aligning features including guide elements and positioning structures that enable the parts to be assembled together without requiring external tools. The shell parts can be manually connected and disconnected by operators, eliminating the need for screwdrivers or other assembly tools while maintaining reliable connection through the interlocking design of the shell parts.

AI summary
An electrical connector (1) with a substantially tubular, angled connector housing (2) comprising a connecting leg (3) and a connecting leg (4), wherein a connecting cable can be inserted into the connecting leg (3) and an insulating body (5) can be inserted or is inserted into the connecting leg (4). According to the invention, the connecting leg (3) has two at least partially channel-shaped shell parts (12, 13) which are detachably connected to one another and axially separable from one another, wherein one of the shell parts (12, 13) is integrally formed with the connecting leg (4). The other free shell part (13) is detachably, and preferably sealingly, fixed to the integrally formed shell part (12). Securing is achieved via a screw connection (16) which is established via a screw sleeve (11).
