A terminal fitting includes a body portion, a first projection, a resilient contact portion and a first fulcrum portion. The body portion is in the form of a rectangular tube open in a front-rear direction. The first projection projects from one wall part toward another wall part, out of two wall parts of the body portion adjacent across one corner. The resilient contact portion is arranged in the body portion. The first fulcrum portion serves as a fulcrum when the resilient contact portion is deflected and deformed. In a developed state of the terminal fitting along the front-rear direction and a width direction, one side end of the resilient contact portion is arranged on one side end part in the width direction. A tip of the first projection is arranged on another side end part in the width direction.

An elastic contact element of the electrical connector is provided and has an upper ring, a lower ring, and a plurality of elastic flat bodies connected to and located between the upper ring and the lower ring. Each one of the elastic flat bodies is strip-shaped and forms a contact portion. The elastic flat bodies are spaced apart from each other and divided into several groups according to different height positions of the contact portions. Each one of the contact portions protrudes toward a center axis. Because the elastic flat bodies are divided into several groups according to different height positions of the contact portions, the elastic flat bodies contact an inserted male probe at various positions.

The embodiments of the present utility model provide a spring leaf, a connection terminal, and an electrical connector, where the spring leaf is provided in a cylindrical housing in a winding manner, and extends outward from a first end to form hangers extending out of the housing. The spring leaf is hung on an end portion of the housing through the hangers, and then the hangers are fixed through an end cover arranged at the end portion of the housing. Thus, the first end of the spring leaf may be fixed through the hangers, and a second end of the spring leaf may move automatically. When a pin is inserted, the compressed spring leaf will not be dislocated, which ensures the contact reliability of the pin with the spring leaf.
