The electrical connector 1 has at least a contact portion 11, a fixing portion 12, a coupling portion 13, and an extending portion 14. A first fixing portion 121 and a second fixing portion 122 are formed at the fixing portion 12 of the intermediate portion of the electrical connector 1. The coupling portion 13 is abutted between the first fixing portion 121 and the second fixing portion 122 to be elastically deformed so that the inner base 3 is freely movable relative to the outer base 2. And the extending portion 14 extends to one of the outer end portions along the first fixing portion 121, and the contact portion 11 extends in a direction suitable for the external contact member 41 to contact and is located at the other one of the outer end portions.

Wherein, the distance between one side of the U-shaped flexible portion 131 and the outer wall of the inner base 3 is larger than the distance between the other side of the U-shaped flexible portion and the inner wall of the outer base 2. Thus, the distance between the inner base 3 and the outer base 2 is different between the two side edges, and the distance between the side edges of the inner base 3 and the outer wall of the outer base is larger in order to keep away from the inner base 3 to achieve the purpose of stress front.

Furthermore, the R-angle connection increases the width of the U-shaped flexible portion 131 at the end and the bottom, and the width of the two sides is smaller, so as to ensure the connection strength and elastic deformation force of the entire flexible portion.

In one embodiment, the second mounting cavity 34 is disposed at a bottom position of the inner base 3, and the second fixing portion 122 and the second mounting cavity 34 are in interference fit with each other.

As is evident, the external base 2 and the internal base 3 are elastically fitted together by means of a plurality of electrical connectors, and the bottom of each base is substantially flush so as to be placed on an external circuit board, implementing an electrical connection of its extension 14 with the outside.

With reference to fig. 8 to 10, the present embodiment further provides a male terminal connector, including: a plug-fit portion 4 and a contact 41. The plug-in fitting portion 4 is adapted to be plugged into the floating female connector, and the contact member 41 is elastically abutted against the contact portion 11 to form a contact connection. In this embodiment, the mating portion 4 of the male connector and the engaging portion 31 of the floating type female connector are mated with each other to form an electrical connection between the two connectors.
