Solution Overview
Problem
Conventional connector structures fail to electrically connect a hollow-core body and a receptacle by rotationally piercing insulating sheaths of wires, making them inconvenient and impractical for use.
Innovation Solution

Engineering Contradiction Analysis
1Ease of operation
If the conventional connector structure is used, then the mounting and operation can be done easily without a dedicated crimping tool, but it fails to electrically connect the hollow-core body and receptacle by rotationally piercing insulating sheaths of wires
Solution Approach 1:
The patent combines two previously separate functions into one integrated connector structure: (1) the mechanical connection function achieved through the hollow-core body and outer ring assembly, and (2) the electrical connection function achieved through metallic spikes that pierce insulating sheaths. This merging allows the connector to simultaneously provide both mechanical support and electrical connectivity without requiring separate crimping tools or additional components.
Solution Approach 2:
The metallic spikes are designed to automatically pierce the insulating sheaths of wires when the connector is assembled, eliminating the need for pre-stripping the insulation or using separate tools. The spikes perform the insulation-piercing action themselves during the normal connection process, making the system self-sufficient and maintaining ease of operation while adding electrical connection capability.
2Reliability
If the metallic spikes pierce through the insulating sheaths of wires, then electrical connection is achieved, but the structure becomes more complex
Solution Approach 1:
The metallic spikes serve multiple functions simultaneously: they act as structural support elements within the connector assembly, provide the piercing action to penetrate insulating sheaths, and serve as electrical contact points for wire connection. This multi-functionality reduces the need for separate components and maintains structural simplicity while achieving reliable electrical connection.
Solution Approach 2:
The metallic spikes act as an intermediary element between the connector body and the wire conductors. Rather than requiring direct contact between the connector and stripped wire ends, the spikes mediate the connection by piercing through the insulating sheath to reach and contact the conductors, simplifying the overall connection process while ensuring reliable electrical contact.
3Ease of operation
If the connection sleeve fits around the hollow-core body and rotates the metallic spikes, then piercing action is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The connection sleeve is designed with rotational movement capability that dynamically transforms the piercing action. As the sleeve rotates during assembly, the metallic spikes are progressively positioned and driven into the insulating sheaths. This dynamic rotational mechanism automatically achieves proper alignment and piercing depth without requiring extremely tight manufacturing tolerances, as the rotation process itself compensates for minor variations in component dimensions.

AI summary
The present invention provides a piercing-through structure for a connector, comprising a hollow-core body, a lead, and a receptacle. Wherein a front connection portion is disposed at a front end of the hollow-core body; a plurality of wires extending forward is disposed at a front end of the lead disposed at a rear segment in the hollow-core body; and a plurality of metallic spikes is disposed at a front end of the connector of the receptacle and a connection sleeve movably fits around a front end of the body. So that connecting the hollow-core body and the receptacle together enables the connection sleeve of the receptacle to fit around the front connection portion of the hollow-core body, allowing the metallic spikes to pierce across surfaces of the wires such that, after piercing insulating sheaths of the wires, the metallic spikes come into contact with metallic cores of the wires, so as to achieve electrical connection of the connector of the receptacle and the wires of the hollow-core body.
