What is the role of the connector, why use a connector?

The connector, as the name suggests, refers to a device that connects two active devices to transmit current or signals. Its function is to build a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. Although the connector looks small, it is an indispensable component in electronic equipment today with such advanced technology. It is widely used and plays a role that cannot be underestimated. In various occasions in our lives, regardless of the electronic products used daily Still in industrial production, there are connectors of various forms and structures.
Some people may question whether it is possible to not use the connector. We can imagine what would happen if there is no connector? At this time, the circuits must be permanently connected with continuous conductors. For example, if an electronic device is to be connected to a power source, the two ends of the connecting wire must be firmly connected to the electronic device and the power source by some method (such as welding). As a result, it brings a lot of inconvenience to both production and use. Take two examples, such as a car battery. If the battery cable is fixed and welded to the battery, the car manufacturer will increase the workload for installing the battery, increasing the production time and cost. When the battery is damaged and needs to be replaced, the car has to be sent to a repair station, and the old one is removed by desoldering, and then the new one is welded. This requires a lot of labor costs. With the connector, you can save a lot of trouble, buy a new battery from the store, disconnect the connector, remove the old battery, install a new battery, and reconnect the connector. Another example is LED landscape lights. The distance from the power supply to the lamp holder is generally relatively large. If each wire from the power supply to the lamp holder is connected from beginning to end, it will bring unnecessary troubles to the construction and cause wires. In addition, if only the conductive parts of the wires are connected together and wrapped with insulating glue, there will be many safety hazards. First, most of the insulating tapes are prone to aging, which is far from meeting the requirements when used in harsh environments. Secondly, the mechanical properties of the joints that are directly lapped together with wires are very poor, and it is easy to cause short circuits. If poor contact causes heat to cause fire, the use of high-performance connectors can not only simplify the construction and installation procedures, but also These safety hazards are reduced to a very low level.
The above two simple examples illustrate the benefits and necessity of connectors. It makes the design and production process more convenient and flexible, and reduces production and maintenance costs. Connectors must be used, and with the level of technology With development, the connector will be gradually upgraded, which will bring greater convenience to the communication of our lives.
