Milton Keynes, UK, September 16, 2011: Cyntech Components, a specialist supplier of electro-mechanical components, announces a two-piece solar PV connector that needs no crimp tool for assembly. The unique design of the IP67-rated connector reduces solar PV system installation time and complexity, and eliminates the need to carry a heavy crimp tool.
To make a reliable connection, the installer simply loosens a screw, inserts the stripped cable into the connector from the back and then presses the spring contact by thumb until its toggle engages. The connector, which has an outer diameter of 18.8mm, is then screwed together and the assembly tightened using two plastic spanners provided. If required, the connection can then be disengaged using one of the multi-function spanners.
The connector system consists of pre-assembled male plugs and female jacks in separate sealed bags, 50 of each per bag. The contacts are made from high quality copper to ensure less than 5mOhm contact resistance (typically 1mOhm to 3mOhm) and negligible power loss. Contacts are rated at 30A and 1000V DC (TUV EN50521) and the connectors are designed to operate in ambient temperatures from -40 to +85 degrees C. They accept cables with an outer diameter of 5.8mm to 7mm and two versions are offered, one for cable cross sections from 1.5mm2 to 2.5mm2 and the other for cables between 4.0mm2 and 6.0mm2.
