Electrical connector and female terminal

1. An electrical connector comprising:

a housing having an assembly receiving space; and

a female terminal positioned in the assembly receiving space and having:

a first female terminal fixed to the housing having a first contact receiving space,

a second female terminal having a second contact receiving space and being independently displaceable in the assembly receiving space relative to the first female terminal and housing along a longitudinal axis, and

an elastic connecting spring having an approximate S-shape connecting the first female terminal to the second female terminal.

2. The electrical connector according to claim 1 , wherein the elastic connecting spring is elastically deformed by a load smaller than a force of insertion and extraction between the second female terminal and a second male contact.

3. The electrical connector according to claim 1 , wherein positions of the first female terminal and the second female terminal are offset, so as to be out of alignment along the longitudinal axis.

4. The electrical connector of claim 2 , wherein a first male contact is inserted into the first contact receiving space.

5. The electrical connector according to claim 4 , wherein the first male contact and the second male contact have different vibration patterns.

6. A female terminal used in an electrical connector, comprising:

a first female terminal having a first contact receiving space;

a second female terminal having a second contact receiving space and positioned offset with respect to the first female terminal so as to be out of alignment along the longitudinal axis, the second female terminal being independently displaceable along a longitudinal axis, relative to the first female terminal; and

an elastic connecting spring having an approximate S-shape connecting the first female terminal to the second female terminal.

7. The female terminal according to claim 6 , wherein the first female terminal is fixed to an electrical connector housing.

8. The female terminal according to claim 7 , wherein the second female terminal is displaceable with respect to the first female terminal portion.

9. The female terminal according to claim 6 , wherein the elastic connecting spring is elastically deformed by a load smaller than a force of insertion and extraction between the first female terminal and the male terminal.

10. The female terminal according to claim 6 , wherein a first male contact is positioned in the first contact receiving space and a second male contact is positioned in the second contact receiving space.

11. The female terminal according to claim 10 , wherein the first male terminal exhibits vibration patterns different from the second male terminal.

12. The female terminal according to claim 6 , wherein the elastic connecting spring further comprises a first arm positioned on a proximate end and a second arm positioned on a distal end.

13. The female terminal according to claim 12 , wherein the first and second arms extend approximately parallel along the longitudinal axis.

14. The female terminal according to claim 12 , wherein the first arm is integrally connected to the first female terminal and the second arm is integrally connected to the second female terminal.

15. The female terminal according to claim 12 , wherein a length of the second arm is greater than a length of the first arm.

16. The female terminal according to claim 12 , wherein the elastic connecting spring is cantilevered, with the first arm and the proximate end of the elastic connecting spring being a fixed end of the cantilever, and the second arm and the distal end of the elastic connecting spring being a free end of the cantilever.
