Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation displacement connectors (IDCs) lack a compact, simple, and reliable design for plug and play connections, particularly for trunk and branch wiring with varying connector intervals, and fail to provide a secure watertight connection for zipcord-type electrical wire.
Innovation Solution
A camlock electrical connector with a first connector member having a bottom platform and upstanding wall with pointed pin elements, and a second connector member with a fulcrum peg that rotates to pierce the electrical wiring, ensuring a secure and watertight connection between zipcord wiring and plug and play cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional IDC designs are used for plug and play connections, then basic electrical connection is achieved, but the connection lacks security and watertight protection
Solution Approach 1:
The connector is divided into two separate members: a first connector member with the platform and pin elements, and a second connector member with the fulcrum peg. This segmentation allows each member to have specialized functions while working together to achieve secure watertight connection.
Solution Approach 2:
The second connector member with the fulcrum peg is inserted into and nested within the first connector member. The peg fits into the opening in the platform, creating a nested structure that enables the camlocking action and secure connection.
2Adaptability or versatility
If fixed connector intervals are used in trunk and branch wiring, then manufacturing is simplified, but adaptability to varying installation requirements is reduced
Solution Approach 1:
The camlock electrical connector is designed as a universal component that can be used in various trunk and branch wiring configurations with different connector intervals. The standardized connector design maintains ease of manufacture while the adjustable positioning capability provides adaptability to varying installation requirements.
Solution Approach 2:
The connector positioning system allows for dynamic adjustment of connector intervals along the trunk wire. The camlocking mechanism enables the connector to be securely positioned at various locations, providing flexibility in spacing while maintaining a standardized connector design.
3Reliability
If simple IDC design is used, then device complexity is reduced, but connection repeatability and reliability are compromised
Solution Approach 1:
The first connector member is pre-configured with the platform, opening, and positioned pin elements before the connection is made. This preliminary preparation ensures that when the second connector member is inserted and rotated, the pin elements are already in the correct position to pierce the insulation and create reliable electrical contact.
Solution Approach 2:
The traditional mechanical crimping or twisting action in conventional IDCs is replaced with a camlocking rotational mechanism. The rotation of the second connector member around the fulcrum peg transforms linear insertion motion into rotational force, which reliably drives the pin elements through the insulation and into the conductor, ensuring repeatable connections.
4Reliability
If non-rotating connector design is used, then device complexity is reduced, but the ability to secure wiring through piercing action is lost
Solution Approach 1:
The connector transitions from a static non-rotating design to a dynamic rotating mechanism. The second connector member rotates around the fulcrum peg, converting linear insertion motion into rotational force that drives the pin elements through the insulation and secures the wiring reliably.
Solution Approach 2:
The camlocking mechanism utilizes asymmetric geometry in the fulcrum peg and its interaction with the first connector member. This asymmetric design creates a mechanical advantage during rotation, allowing the pin elements to be driven effectively through the insulation with controlled rotational motion.

AI summary
A camlock electrical connector has a first connector member with a bottom platform having an opening and an upstanding wall. Pin elements extend outwardly from the wall and a cable connector extends outwardly from and externally of the wall. A second connector member has a connector body with a fulcrum peg extending downwardly from the body. The peg is inserted into the opening in the platform, such that the second connector member is rotatable in relation to the first connector member. When electrical wiring is positioned between the wall of the first connector and the body of the second connector member, rotation of the second connection member and its peg in relation to the first connection member causes the pin elements to pierce the electrical wiring, thereby securing the wiring to the electrical connector.
