The influence of appearance factors on the terminals: The terminals play an important role in the appearance of the product and the affinity for the user. The power terminals must be easily installed on site because they are often installed at the front end of the easy-to-see product panel. In this way, marketers often want to have a say in the appearance of the power terminal block products. In the series of preferred terminals with a rated cross section of up to 10 mm2, the crimping frame is constructed using a lifting cylinder. Their principle of action is based on the so-called "lifting cylinder principle". When the screw is tightened, the screw is placed on the conductor to move the crimping frame upward, thereby causing the wire in the crimping frame to be pressed against the conductor and finally clamped. Due to the high contact force of the UK terminals, the wires can be embedded in the soft tin plating of the conductor. In this way, the transition resistance obtained at the 4mm2 terminal is only 0.3Ω, which is significantly lower than the minimum value required by the IEC947-7-1/EN60947-7-1 standard. In this crimping frame structure, the "Reakdyn-" on the upper part of the lifting cylinder The gap" realizes the screw self-locking. Increase the torque to tighten the screw and the lift cylinder is elastic. In order to adapt to the product's high temperature resistance, low temperature, flame retardant, to ensure that the geometric dimensions of the parts are stable and reliable.
Most of the terminal block insulators are molded using thermoset plastics. The interface sealing body and the sealing body are formed by molding with silicone rubber. Contact body - pin jack is the general name of contact body, divided into welding type, crimp type and wrap-around type, etc., used to realize circuit connection.
