What connections are available for aviation sockets?

Aviation sockets are electromechanical components connected to electrical circuits, so the electrical parameters of the aviation plug itself is the first thing to consider when choosing an aviation plug, and the correct selection and use of aviation plugs is an important aspect of ensuring the reliability of electrical circuits.1, Aviation socket termination: termination refers to the contact pair of an aviation plug and the connection of wires or cables. Reasonable choice of termination and the correct use of termination technology is also an important aspect of the use and selection of aviation plugs.2, the installation and shape: the installation of aviation plugs have a front and rear installation, installation and fixing methods such as rivets, screws, card ring or the aviation plug itself card pin quick lock. There is also a plug and socket are free end aviation plug, the so-called relay aviation plug. 3, aviation socket welding: welding is the most common soldering. Tin welding connection is the most important is the solder material and be welded between the surface should form the continuity of the metal. Therefore, for aviation plugs, the important thing is weldability. The most common platings on the soldered end of aviation plugs are tin alloy, silver and gold. Reed type contact pairs of common welding end of the solder lug type, punch eye solder lug type and notched solder lug type: pinhole type contact pairs of common welding end of the drilled arc notch type. 4, aviation socket winding connection: winding connection is the wire is directly wrapped around the prongs of the contact with the prongs of the contact piece winding column. Winding, the wire is wound under controlled tension, pressed into and fixed in the prongs of the contact winding column to form an airtight contact. Winding wire has several requirements: the nominal value of the diameter of the wire should be in the range of 0.25mm ~ 1.0mm; wire diameter is not greater than 0.5mm, the extension of the conductor material is not less than 15%; wire diameter is greater than 0.5mm, the extension of the conductor material is not less than 20%. Winding tools include winding gun and fixed winding machine. 5, aviation socket crimping: crimping is to make the metal in the specified limits of compression and displacement and will be connected to the conductor contact pair on a technology. Good crimping connection can produce metal intermelt flow, so that the wire and contact pair material symmetrical deformation. This connection is similar to a cold soldered connection and gives better mechanical strength and electrical continuity, it can withstand harsher environmental conditions It is generally accepted that the use of a properly crimped connection is better than soldering, especially in high current situations where crimping must be used. Crimping shall use special crimping pliers or automatic, semi-automatic crimping machine. Should be based on the cross-section of the wire, the correct choice of contact on the wire barrel. It should be noted that the crimp connection is a permanent connection, can only be used once. 6, aviation socket screw connection: screw connection is the use of screw-type terminal connection, pay attention to the maximum and minimum cross-section of the allowable connecting wires and different specifications of the screws allow the maximum tightening torque. 7, aviation socket puncture connection: puncture connection, also known as insulation displacement connection, was invented in the 60's by the United States of America, a novel end of the technology, with reliability, cost and performance. Technology, with high reliability, low cost, easy to use, etc. has been widely used in a variety of printed circuit board with electrical connectors. It is suitable for the connection of ribbon cable. Connection does not need to strip the cable insulation, relying on the aviation plug "U" contact reed tip into the insulation, so that the cable conductor slides into the contact reed groove and is clamped, so that the cable conductor and the aviation plug reed to form a close electrical connectivity between. It requires only a simple tool, but cables of the specified gauge must be used.
