Connectors are a component that our electronic engineering technicians often come into contact with. Its role is very simple: to bridge the communication between the blocked or isolated circuits in the circuit, so that the current flows, so that the circuit achieves the intended function. Connectors are an indispensable part of an electronic device. You will always find one or more connectors when you look at the path through which the current flows. The form and structure of the connector are ever-changing. There are various types of connectors depending on the application object, frequency, power, and application environment.
For example, the connector for lighting on the court and the connector for the hard drive, as well as the connector for igniting the rocket, are quite different. But no matter what kind of connector, it is necessary to ensure smooth and continuous current flow. In general terms, the connection of the connector is not limited to current. In today's rapid development of optoelectronic technology, in the optical fiber system, the carrier that transmits the signal is light, and the glass and plastic replace the wires in the ordinary circuit, but the optical signal Connectors are also used in the vias, which function the same as circuit connectors.
A connector is a motor system that provides a detachable interface for connecting two secondary electronic systems without unacceptable effects on the operation of the system. The key words in the definition are "motor system", "separable" and "unacceptable effect". A connector is a motor system because of its electrical connection that is produced mechanically. As will be discussed, the deflection of the mechanical spring creates a force between the mating portions, which creates a metallic contact between the mating faces of the interface. The reason why the application connector is in the first place is that the interface is separable. The need for separability has many reasons. It allows for the manufacture of parts or subsystems independently and the final assembly can be done in one main place. Separability also allows maintenance or upgrades of parts or subsystems without having to modify the overall system. Another reason for the separability to be applied is portability and support for the expansion of peripherals.
Trends in SMD Components Since the 1950s, surface mount technology (SMT) has been used by some manufacturers. However, the use of SMT connectors has only recently begun, and has gradually been valued by more manufacturers. The reason for this may be that the use of SMT connectors will face technical challenges and will not make users feel that SMT can effectively save board space. With the development of the times, connectors have become the few remaining perforated parts on most PC board. Manufacturers have also found that by reducing the use of hybrid soldering techniques (ie, using both surface mount and perforated components on the same board), all SMT processes can increase productivity and reduce costs for manufacturers. Engineers have found that SMT can help manufacturers make more use of both sides of the board to reduce the board area and reduce the production process. In addition, perforated components require a larger pitch for soldering, while surface mount connectors provide a tighter pitch and ensure soldering quality, giving manufacturers more flexibility. 2. Common lead-type connector lead method 2.1. Conventional surface-mount connector According to the shape and use of SMT parts, the more common lead structures are seagull type, J type and parallel type (see figure ). Each lead construction has its own unique properties, features and uses. Seagull is the most common type of lead construction in the lead construction of SMT connectors. Although J-type leads can provide better solder thickness and interface, the manufacture of J-type leads often requires the use of more complex and expensive forging beds. After the finished product, it can not provide users with any technical and technological advantages. Parallel lead constructions are found to lack the surface area that the leads should contact the pads. However, the ability to provide good lead and soldering contact is a real concern for SMT users. Practice has shown that the parallel leads can provide less than half the force of the seagull or J-lead after welding.
Board-to-board connectors are the most powerful connector products of all connector product types, mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing, etc. industry.
At present, the main spacing of the board-to-board connectors is 0.4mm, 0.5mm, 0.635mm, 0.8mm, 1.00m, 1.27mm.

With the development of the economy, more and more places now need to use gadgets. Although the tools are small, the role is very large. For example, the terminals we often see, a small appliance, can be seen everywhere, but its role is very meaningful for the entire circuit, or the entire mechanical engineering. For example, in a circuit line, there may be an infinite number of interfaces, and these interfaces need to be connected by a small tool. These small tools are called terminals, and one of the numerous gadgets is small. The tool, the meaning of the whole device is very large.
The most common place for terminal blocks is in the circuit, except for some other places in the circuit. For example, mechanical equipment, where connectors are needed, these terminals are equivalent to a small connector, giving some performance the same. Or different devices are connected together to ensure that some components can run smoothly or ensure that the current can flow smoothly, so that the entire device can operate. The materials of these terminals are mostly not the same, because the nature and function of the places used are different, so the materials will be different, some need metal, some need plastic, some need liquid Some need solid, in short, the selection is based on the specific circumstances.
In addition, the shape of these terminals is very different, some are round, some are square, some have holes, some have no holes, and some are connected inside the parts, some are Connected to the outside of the part. The working principle of these connectors is also very different, some are plugged in, some are embedded, some are spring-type, and some are fence-type. Experts from Qingda Electronics believe that the needs of each place are different and the design will be different. These terminals are widely used in our daily life. Some are used in large industrial areas, while others are used in small household appliances and home circuits, which play an irreplaceable role in the improvement of this system. The terminals here are equivalent to a complete connector device that is needed around our lives.
