Abstract
The invention, which belongs to the technical field of an electric connector, discloses a method of flexible force application connection for an elastic contact pair of an electric connector. The electric connector has a plurality of contact pairs that are composed of contact As (1) and contact Bs (4), wherein each contact pair has at least a flexible contact as a contact. Each contact A (1) and each contact B (4) are respectively fixed on insulating fixed parts (5), and the insulating fixed parts (5), which are used for fixing contact the As (1) and the contact Bs (4), are arranged oppositely. After the insulating fixed parts (5) are connected and put in place at an outer shell, the two insulating fixed parts (5) are motionless relatively. When flexible contacts make a contact at two contact surfaces, the flexible contacts themselves make displacement; meanwhile, reaction forces are exerted on contact surfaces of the contact pairs, so that the contact pairs are connected tightly by the reaction forces, and thus an objective that a power supply or an electrical signal is connected by a small contact resistance can be achieved. According to the invention, the electric property, the mechanical property, and the reliability of the connection of the electric connector can be improved, and the service life of the contact pairs can also be prolonged.
