Reasons for use
　　Imagine if there would be no connector? At this time the circuit between the use of continuous conductor to be permanently connected together, for example, the electronic device to be connected to the power supply, must be connected to both ends of the wire, and electronic devices and power through a certain method (such as welding) fixed firmly. As a result, both for the production or use, have brought a lot of inconvenience. Take the car battery as an example. Assuming that the battery cable is fixed to the battery, the car manufacturer increases the amount of work required to install the battery, increasing the production time and cost. Battery damage need to be replaced, but also the car to the repair station, desoldering demolition of the old, and then welding on the new, to pay more labor costs. With the connector can be a lot of trouble, buy a new battery from the store, disconnect the connector, remove the old battery, install a new battery, re-connect the connector on it. This simple example illustrates the benefits of the connector. It makes the design and production process more convenient and more flexible, reducing production and maintenance costs.
