insulator material barrier terminal block used

Data transfer is not current fluctuations through, but by pulsating waves, using a special optical fiber as the medium. From the output port fiber terminal blocks, you can see the red light, it is not a WISDOM HDMI CABLE  laser, nor be harmful to the human eye. Dirt and dust hinder the transmission of light, so do not touch the connector when used, they also do not want dust caps to the port, in addition, fiber optic cable can not bend excessively distorted, otherwise it will cause permanent damage can not be used. Optical and electro-optical fiber terminal requires two conversions, will inevitably lead to loss of the phenomenon, but unlike copper fiber susceptible to electromagnetic interference, the long-distance transmission can have a better guarantee. Same element group, before the number preceded by the letter, if not necessary to distinguish phase, available digital-5N, -2.5, -16 mark.
Factors affecting the appearance of terminals: Terminal affinity in terms of appearance and the user have played an important role, power  WISDOM RAC CABLE terminals must be easy on-site installation, as they are often mounted on the front panel is easy to see the product. Thus, marketers often want the appearance of power terminal block products have some say. Rated cross-section to the preferred terminal series 10mm2, the pressure drum lifting frame structure are used. Their role is based on the principle of so-called "lift cylinder principle" as the basis. When tightening the screws, the WISDOM hdmi wall plate  screws on the top of the conductor leaving Clamp upward movement, thereby Clamp the wire conductor and eventually tie tightly clamped. Since UK terminals can have a high contact force electrical conductor wires embedded in a soft tin plating layer. Tighten the screws to increase the lift cylinder shaped elastic. In order to meet the high temperature, low temperature, flame retardant, to ensure stable and reliable part geometry. Terminal block insulator mostly using thermoset molding. Interface seal body with silicone rubber seal line body molding and other molding. Preloaded - pin jack is touching the body, collectively, into welded, crimp and fit around, etc., used for electrical connections.
