6. The electrical connector of claim 2, wherein the through hole has a fixing slot for receiving the fixing member.
7. The electrical connector of claim 1, wherein the electrical terminal further includes a fixing member, and wherein the resilient member and the fixing member define a radius R.
8. The electrical connector of claim 1, wherein the contact member has a guiding member at an end thereof being at an angle relative to the contact member.
9. The electrical connector of claim 1, further comprising an actuation device including a spindle parallel connecting to the cover, and an eccentric camshaft connecting between the cover and the insulating housing, whereby the cover is mobile between the open position and the locked position relative to the insulating housing by rotating the eccentric camshaft.
10. The electrical connector of claim 3, wherein increasing the radius R increases the preload applied to the contact member by the projection.
11. The electrical connector of claim 7, wherein increasing the radius R increases the preload applied to the contact member by the projection.
12. The electrical connector of claim 1, wherein the electrical terminal includes a tail member at a location furthest away from the contact member.
13. The electrical connector of claim 3, wherein the tail member extends from the radius R in a direction away from the contact member.
14. The electrical connector of claim 7, wherein the tail member extends from the radius R in a direction away from the contact member.
