Tyco Solarlok

Solarlok is a largely obsolete electrical connector used to connect solar panels together. Solarlok was introduced by Tyco International in order to meet new National Electrical Code (NEC) standards that required panel connectors to lock together and only be separated again using a tool. Solarlok became very common in the United States where the code first came into effect, but had varying degrees of market success outside the US. Due to the connector only being available from Tyco, the connectors are almost always referred to simply as Tyco connectors.
