In power automation connection systems, cold compression terminals with their simple construction and wide range of types offer thousands of solutions for power partners. The advantages of the terminals will be realized especially when the connection terminals are short-circuited due to burnout. After cutting off the power supply, the burnt terminal can be immediately removed and replaced with a new product of the same type, shortening the maintenance time. What are the connection methods for cold pressed terminals? Is it similar? One: Screw connection Screw connection is a connection method using screw terminal blocks. Note that different sizes of screws allow for larger and smaller cross-sections as well as larger tightening torques. II: Soldering The most common type of soldering is welding. The most important aspect of a soldered connection is the metallic continuity between the solder and the surface to be soldered. Therefore, weldability is important for terminal blocks and cold pressed terminals. The most common coatings on the solder side of wire loop terminals are tin alloy, silver and gold. Reed type contacts have a solder type for the common solder side, a punched solder type and a notched solder type: pinhole contacts have a drilled arc notch type for the common solder side. III: CrimpingCrimping is a technique used to compress and displace metal within specified limits and to connect wires to contact pairs. A good crimped connection produces an intermelt flow of metal that symmetrically deforms the conductor and contact pair material. This connection is similar to a cold welded connection, allowing for better mechanical strength and electrical continuity, as well as the ability to withstand harsher environmental conditions. At present, a properly crimped connection is generally considered superior to soldering, especially in high-current situations where crimping must be used. Special crimping pliers or automatic or semi-automatic crimping machines must be used. Depending on the wire cross-section and cold crimp end of the cold crimp terminal, the correct barrel should be correctly selected. It should be noted that crimp connections are connections that can only be used once. IV: Winding Connection Winding is done by winding the wire directly onto the winding post with an angular contact piece. The wire is wound under controlled tension, pressed into and secured to the corner of the contact member winding post to form an airtight contact. Five: puncture connection puncture connection has high reliability, low cost, easy to use. It has been widely used in a variety of printed board terminals and cold pressed terminals. Heads in ring terminals. Suitable for connection of ribbon cable. No need to strip the insulation of the cable when connecting. The "U" shaped contact reeds of the terminal pierce the insulation so that the cable conductors slide into the grooves of the contact reeds and are clamped. All rights reserved, so that a tight electrical connection is formed between the cable conductor and the terminal reed. It requires only simple tools, but it is important to select a cable with the specified gauge.
