In order to improve residential electricity consumption condition, our company develops FJ6/JHD series terminal block .This kind of

terminal block enables the operation to be more convenient, and also guarantees reliable connection, and finally reaches the aim of safety

in utilizing electric energy. This products get high appreciation from the energy measuring operators one-meter”and standardization

of energy measuring devices as well as standardized management. The products are also honored as national high-quality technological

products and  are recommended for application by national electric power bureau.



Application of this terminal block enables house service wire to be separated from meter service wire, which solves the

problem of parallel connection. Terminal block cover can be sealed to prevent electricity theft ; Neutral line terminal block can

be earthed repeatedly. It is in conformity with the“special, sealed”principle standardization of one-household one-meter. The products

are applied in“one-household one-meter”electric energy metering box.


三、Structural features

This series of terminal block adopt high-molecular polycarbonate material imported from America. It has advantages of high

impact resistance, moisture resistance, favorable insulation; ageing resistance, flame retardant, high temperature resistant, etc..

The binding screw adopts compound recess , which is suitable for flathead screwdriver and crossed screwdriver The products are popular

due to compact volume, large capacity, high withstand voltage, reasonable structure, and elegant appearance.
