TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If protective arrangements are added to prevent secondary circuit disconnection, then reliability improves, but device complexity increases
Why choose this principle:
The protective function is merged with the normal connector components. The resilient contact serves dual purposes: it acts as a regular electrical contact during normal operation and simultaneously provides protective connection when the plug is disconnected. The insulating pin also serves dual functions as both an electrical insulator and a mechanical indicator of disconnection state, eliminating the need for separate protective mechanisms.
Principle concept:
If complex protective arrangements are implemented, then reliability improves, but ease of manufacture deteriorates
Why choose this principle:
The connector structure provides self-protection through its inherent design. When the plug part is disconnected, the resilient contact automatically maintains connection with the pin connector through its elastic properties, and the insulating pin automatically indicates the disconnection state. This self-service mechanism eliminates the need for complex external protective devices and simplifies manufacturing.

Abstract
The invention relates to an electrical connector arrangement having a plug part (3) and a socket part (2). The socket part comprises a pair of connectors (4A, 4B), and the plug part a pair of pin connectors (5A, 5B). Each connector (4A, 4B) of the socket part comprises a pin connection (6A, 6B) for a current transformer, a contact portion (7) being arranged to be connectable with an opposed pin connector (5A, 5B) of the plug part, and a resilient contact (8) being arranged to be connectable with the resilient contact (8) of the other connector of the pair. The plug part (3) comprises an insulating pin (9) being arranged to switch off the connection between the resilient contacts (8) when the plug part (3) and the socket part (2) are connected to each other, and to switch on the connection between the resilient contacts (8) when the plug part (3) and the socket part (2) are decoupled from each other
