1. What is a connector?
The connector, that is, CONNECTOR. It is also known as plug in, plug and socket in China. In general, it refers to electrical connectors. A device that connects two active devices to transmit a current or signal.

Connectors are one of the parts of our electronic engineering technicians. Its role is very simple: in the circuit is blocked or isolated circuit between, set up a bridge of communication, so that the current flow, so that the circuit to achieve a predetermined function. The connector is an indispensable part of the electronic device, and you will always find one or more connectors following the current flow path. The form and structure of the connector are varied. With the different applications, frequency, power, application environment, and so on, there are various types of connectors. For example, the connector on the stadium and the connector of the hard drive, and the connector that ignites the rocket, is quite different. But no matter what kind of connector, it is necessary to ensure that the current is smooth and continuous and reliable circulation. It refers to, connectors are connected is not limited to the current, with the rapid development of optoelectronic technology today, optical system, the transmission signal vector is light, glass and plastic instead of the common circuit wire, but also use the connector optical signal pathway, and they are of the same circuit connector. Since we are only concerned about circuit connectors, we will closely integrate Molex products with the introduction of circuit connectors and their applications.

2. Why do you want to use connectors?
Imagine what would happen if there was no connector. At this point, the circuit must be connected permanently by continuous conductors. For example, when the electronic device is connected to the power supply, the two ends of the connecting wire must be fixed to the electronic device and the power by some way, such as welding. In this way, it has brought a lot of inconvenience to both production and use. Take car batteries for example. Assume that the battery cable is fixed firmly on the battery, car factory for the installation of the battery will increase the workload, increase the production time and cost. The damage to the battery needs to be replaced, will be sent to the vehicle maintenance station, connecting the demolition of the old, and then welded on the new, so to pay more labor costs. With connectors, you can save a lot of trouble, buy a new battery from a store, disconnect connectors, remove old batteries, install new batteries, and reconnect connectors. This simple example illustrates the benefits of the connector. It makes the design and production process more convenient and flexible, and reduces the cost of production and maintenance.
