Furthermore, the contact structure 6 of the at least three elastic clamping arms 5 provides electrical connection with the matching male connector.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
