Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angled multicontact connectors face issues with short circuits due to incorrect clipping of contacts, and previous solutions involving bent or hinged parts are costly and limit the choice of insulating materials, making assembly difficult and costly.
Innovation Solution
An angled multicontact connector design featuring a U-shaped insulating part that is inserted transversely to retain and separate contacts, preventing short circuits and allowing for easy assembly, with no specific material constraints and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contacts are clipped into grooves in the insulator body, then contacts are retained in position, but short circuits may occur with the shielding conductive body
Solution Approach 1:
An insulating part is introduced as an intermediary element between the contacts and the conductive body. This insulating part includes retention elements that engage with the contacts and an insulating surface that prevents electrical contact with the conductive body, thereby eliminating the short circuit risk while maintaining contact retention
Solution Approach 2:
The insulator is divided into two functional parts: the main insulator body with grooves for contact positioning, and a separate insulating part that provides both retention and electrical isolation. This segmentation allows each part to perform its specific function optimally without interference
2Object-affected harmful factors
If bent over tongues are added to the insulator to prevent short circuits, then short circuit risk is reduced, but assembly becomes difficult and material choice is limited
Solution Approach 1:
The insulating part is designed to be self-retaining through clipping mechanisms that engage with the insulator body. Once inserted, the insulating part automatically secures itself without requiring manual holding or additional fastening operations, making assembly simple and intuitive
Solution Approach 2:
The insulating part serves multiple functions simultaneously: it provides electrical isolation from the conductive body, retains the contacts in position, and separates adjacent contacts from each other. This multi-functionality eliminates the need for separate components for each function
3Reliability
If hinged parts are used to trap and insulate contacts, then contacts are immobilized and insulated, but production cost increases and fragility increases
Solution Approach 1:
The insulating part is designed as a simple, inexpensive component made from standard insulating materials. It is a non-fragile, easy-to-manufacture part that can be produced at low cost using conventional processes, eliminating the need for expensive and fragile hinged mechanisms
Solution Approach 2:
The design transitions from complex hinged mechanisms to a simple inserted component. The insulating part uses basic geometric features and material properties rather than mechanical hinges, fundamentally changing the approach from complex movable parts to simple static insulation

AI summary
An angled multicontact connector comprises at least two angled contacts, an insulative angled body made of an insulative material, a conductive angled body made of a conductive material, a conductive material cap adapted to be fixed to the cable and to close the conductive angled body around the angled contacts. The insulative angled body includes at least one groove open toward the outside, each groove being adapted to receive at least in part the rear end of one of the angled contacts. The angled multicontact connector further includes an insulative material part adapted to be removably fixed to the insulative angled body to retain the rear end of the angled contacts not received in a groove and to separate each rear end from the rear end of any other angled contact, and from the conductive cap when the conductive cap is in a position closing the conductive angled body.
