Insulation Displacement Connector Piercing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation displacement connectors require stripping of electrical insulation from cables for connection, which is inconvenient and can lead to errors or damage.
Innovation Solution
An insulation displacement contact with a conductive contact body featuring a mating portion that includes a slot and piercing members to pierce the cable's insulative layer, allowing direct contact with the conductor without stripping, and a mounting portion for attachment to a complementary electrical component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional insulation displacement connectors are used, then electrical connection is achieved, but insulation stripping is required which is inconvenient and can lead to errors or damage
Solution Approach 1:
The piercing member is extracted as a separate functional element within the contact body, specifically designed to pierce through the cable insulation layer and directly contact the conductor, eliminating the need for manual insulation stripping operations
Solution Approach 2:
The contact body performs self-service by integrating the piercing function directly into the connection process, where the piercing member automatically penetrates the insulation layer when the cable is inserted, without requiring external stripping tools or operations
2Reliability
If insulation stripping is required for connection, then reliable electrical contact is achieved, but the process becomes time-consuming and complex
Solution Approach 1:
The piercing function and electrical contact function are merged into a single integrated contact body structure, where the piercing member and contact surface work together in one component to simultaneously achieve insulation penetration and reliable electrical connection
Solution Approach 2:
The piercing member is pre-configured within the contact body to perform the insulation penetration action automatically when the cable is inserted, preparing the path for electrical contact before the actual connection is made
3Productivity
If manual insulation stripping is performed, then cable connection is possible, but productivity is reduced due to additional steps
Solution Approach 1:
The contact body performs self-service by integrating the piercing function directly into the connection process, where the piercing member automatically penetrates the insulation layer when the cable is inserted, without requiring external stripping tools or operations
Solution Approach 2:
The contact body is segmented into distinct functional zones including the piercing member portion and the contact portion, allowing each segment to perform its specific function efficiently within the unified structure

AI summary
An insulation displacement contact comprises an electrically conductive contact body including a mounting portion that is configured to receive a complementary electrical component so as to contact an electrical terminal of the complementary electrical component, and a mating portion configured to attach to an electrical cable, the mating portion including a slot that extends into the contact body, and at least one piercing member that at least partially defines the slot such that, when the slot receives an electrical cable, the piercing member pierces an outer electrically insulative layer of the electrical cable and contacts an electrical conductor of the electrical cable that is disposed inside the electrically insulative layer.
