Currently, a brand new connection terminal - JH27 series connection terminal comes out. The product is better than current various large current connection terminals in the use convenience, performance reliability, structure uniqueness and functional completeness. The product is composed of the insulation base wire frame and protective cover. The wire frame is composed of a conductor grip, screws, nuts and a bearing frame. The contact surface of the conductor grip and conductor is of interlocking structure being containment shaped, which is characterized by the large contact surface and reliable　compression joint. The mutual combination of conductor grips in different shapes not only makes the

makes the product have general functions of currently used connection terminal but also derives large current branching terminals. It meets various purposes of large cross-section conductor connection, conductor branching, etc. in all electric control distribution and complete devices. The unique structure of conductive parts makes conductor access more convenient so that the conductor access can be made only after the conductor terminal insulation is removed, without any treatment on the conductor terminal and no longer needs large number of accompanied tools. The product is in ease of use and doubles efficiency. The product's insulating material uses the high quality reinforced engineering plastics. The material has excellent electrical performance, flame resistance, corrosion resistance and excellent mechanical performance, as well as relatively strong anti-vibration and shock resistance. Main experimental data is as follows: voltage drop of 0.98mV, temperature rise of 27K, short-circuit current intensity of 120A/mm² (rated cross section). The developed product meets the demand of industries on the large cross-section conductor connection. It can be believed that the introduced JH27 series connection terminal will certainly benefit to users of electric control distribution industry.

    The product meets the IEC60947-7-1 and GB14048. 7. 1he JB/9659.1 standard.
    This product has applied for a patent, patent No: 03230688.1
