Do You Know How To Connect Several Terminals

1. Screw connection

Screw connection is the connection method of using screw terminal blocks. Aoyu terminal blocks remind you to pay attention to the maximum and minimum cross-sections of the connection wires and the maximum tightening torque allowed by screws of different specifications.

2. Welding

The most common type of soldering is soldering. The most important thing in soldering connection is the continuity of the metal between the solder material and the surface to be soldered. Therefore, solderability is important for wiring terminals and cold-pressed terminals. The most common coatings on the solder side of the wire ring terminal are tin alloy, silver and gold. The reed type touch has a solder blade type, a punched solder blade type and a notched solder blade type for the common welding ends: the pinhole touch has a drilled arc notch type for the common welding ends.

3. Crimp

Crimping is a technique for shrinking and displacing metal within regular limits and connecting wires to the touch pair. A good crimping connection can cause metal mutual fusion flow, so that the wire and the touch pair material are deformed symmetrically. This connection is similar to the cold welding connection, which can obtain better mechanical strength and electrical continuity, and it can withstand more severe environmental conditions. It is now generally believed that it is better to choose the correct crimp connection than soldering, especially in high-current situations where it is necessary to use crimping. Special crimping pliers or automatic or semi-automatic crimping machine must be used for crimping. According to the wire section of the cold-pressed terminal and the cold-pressed end, the wire barrel that is the right touch should be selected correctly. It should be noted that the crimping connection is a permanent connection and can only be used once.

4. Winding

Winding is to wind the wire directly on the winding post of the touch piece with edges and corners. When winding, the wire is wound under tension control, pressed into and fixed at the corners of the winding post of the touch piece to form an air{{0}}tight touch. There are several requirements for winding wires: the nominal value of the wire diameter should be within the range of 0.25mm1.0mm; when the wire diameter is not greater than 0.5mm, the control engineering network copyright, the elongation rate of the conductor material is not less than 15 percent ; the wire diameter is greater than When 0.5mm, the control engineering network is copyright, the elongation of the conductor material is not less than 20 percent . Winding things include winding guns and fixed winding machines.

5. Continuous puncture

Piercing connection, also known as insulation displacement connection, is a novel terminal technology invented by the United States in the 1960s. It has the characteristics of high reliability, low cost, and convenient use. Now it has been widely used in various printed board terminals. Cold-pressed terminal, cold-pressed end, ring terminal. It is suitable for the connection of ribbon cables. When connecting, there is no need to strip the insulation layer of the cable. The tip of the "U"-shaped touch reed of the terminal is pierced into the insulation layer, so that the conductor of the cable slides into the groove of the touch reed and is clamped. All rights reserved, so that a tight electrical connection is formed between the cable conductor and the terminal reed. It only needs simple things, but it is necessary to select cables with regular wire gauges.
