Terminal blocks invention nearly a century, in the past hundred years, the industry heavyweights - Phoenix constantly adapt to different functions of the various areas of new products, making electrical equipment, control cabinet wiring more convenient . With the increase in the types of terminal blocks, terminal blocks market also began to refine, favored product will gradually prominent. According Champ electronic marketing experience derived: the most popular on the market straight welded terminals PCB terminal blocks, partly because LED requires a lot of areas of the series terminal blocks, on the other hand, the series has a variety of terminal blocks feature user-friendly connection. Here to tell us about the series terminal blocks functions.

       Most PCB solderability terminal blocks made of an insulating member, the pressure frame, a conductive member, consisting of screws, pieces of insulation material is PA66, flame retardant grade V0, pressure frame is nickel plated brass, high-precision screw nickel-plated copper alloy, conductive member is phosphor bronze matte tin plated, high antioxidant properties.

       A pitch and volume

       PCB terminal blocks solderable 2.54 / 3.5 / 3.81 / 5.0 / 5.08 / 6.35 / 7.5 / 7.62 / 9.52 / 10.16 other pitch Alternatively, at the same time, such as 5.0 pitch of another KF127 / KF128 / KF129 three kinds different terminal blocks volume, different volume sizes, access to the wire diameter is different, KF127 smaller access diameter is 0.14-1.5mm2, while larger KF129, accessible 0.2-2.5mm2 wire diameter.

       Second, high-low

       Existing PCB solderability terminal blocks have single, double and triple three different high and low points of the terminal blocks. Double terminal blocks to meet the printed circuit board element concentration required for connecting wires Cheats trend. Staggered between terminal blocks on the lower half of each pitch, to ensure that the lower wiring bits are not connected to the upper wire covered live, to facilitate the operation of the lower layer wiring. Double terminal blocks can be connected together by a single keyway and terminal blocks, solder pin pitch remains unchanged. Double major products are KF127A-5.0 / 5.08, KF127B-5.0 / 5.08, KF128A-3.5 / 3.81, KF128B-3.5 / 3.81, KF128A-5.0 / 5.08, KF128B-5.0 / 5.08, KF128AA-5.0 / 5.08, KF128BB-5.0 /5.08, KF129A-5.0 / 5.08, KF129B-5.0 / 5.08, KF129C-5.0 / 5.08, KF635A-6.35, KF635B-6.35, KF950A-9.5, KF950B-9.5. there are three major products KF128A3-5.0 / 5.08.

       Third, the connection angle

       According to customer needs, Champ electronic production line terminal blocks 45 °, the looper series terminal line of 90 °, 180 ° needle straight into the line of series terminal blocks.

       Fourth, wiring

       PCB straight welded wiring terminal blocks in three ways: with box, retaining wire and slide type.

       Box Line is pressed by rotating the screw will move the frame, so that the standoff between the press frame and the conductive member, to achieve close contact, such as KF128-5.0 / 5.08;

       Terminal blocks care line is by tightening the screws so that the screw press down spring sheet, which will hold the wire, all while protective conductor is not in direct contact with the screws and wire damage, KF300R-5.0 is to use the terminal wiring ;

       Slider type terminal blocks is caused by screwing the screw is rotated so as to slide in the pressure line fixed wire frame, curved Crimping block mounted on the body bag-pressure line, for the axis of the anchor can swing freely. Tighten the screws connecting the wires, curved line pressure will force the screw turned and zoom in until it pressed against the wire to the terminal strip stripes. Wire and screwdriver in direction of operation must be balanced occasions, this terminal blocks has obvious advantages, such as KF141V-2.54.

       All wiring has an advantage is to protect the wire intact.

       PCB straight welded terminal blocks account for a large share of the market, widely used in ballast, communications power supplies, power control, power systems, power modules, solar power, wind power, water supply, power supply and other areas of the ship
