Abstract

Electromagnetic shielding about a part connected with a wiring board is easily and reliably carried out by a simple configuration. An electrically-conductive cover member provided at a mating retaining member of both of electric connectors is provided with a cover contact-point part contacting an electrically-conductive shell of a counterpart connector when the mating retaining member is subjected to a turning operation, and the electrically-conductive cover member is subjected to the turning operation together with the mating retaining member, thereby covering the connection part of the counterpart connector mounted on a wiring board and the wiring board by the electrically-conductive cover member, carrying out electromagnetic shielding with respect to the part connected with the wiring board; and, by forming a ground circuit by grounding the electrically-conductive cover member through the cover contact-point part of the electrically-conductive cover member and the electrically-conductive shell, further good electromagnetic shielding characteristics (shield characteristics) are configured to be obtained.

First claim

a mating retaining member provided in the first connector is configured to be subjected to a turning operation so as to cover, from an outer side, an electrically-conductive shell provided in the second connector when both of the first and second connectors are mated with each other,
a mated state of mutually mating both of the first and second connectors is retained by the turning operation of the mating retaining member,
an electrically-conductive cover member provided at the mating retaining member covers a part of the second connector connected with the wiring board, and
the electrically-conductive cover member is provided with a cover contact-point part that becomes a connected state with respect to the electrically-conductive shell of the second connector in the case of the turning operation of the mating retaining member.

2. An electric connector comprising:
a terminal part of a signal transmission medium that is coupled to the electric connector;
a mating retaining member that is configured to be subjected to a turning operation so as to cover, from an outer side, an electrically-conductive shell provided in a counterpart connector when the connector is mated with the counterpart connector mounted on a wiring board in a connected state, wherein
a mated state of mutually mating the electronic connector with the counterpart connector is retained by the turning operation of the mating retaining member;
an electrically-conductive cover member provided at the mating retaining member covers a part of the counterpart connector connected with the wiring board; and

the plurality of elastic spring members are formed so as to be bent at an intermediate position of a part extending in a cantilever shape and extended; and
the cover contact-point part is formed at an extending-direction distal end part of the plurality of elastic spring members.

8. The electric connector device according to claim 7 , wherein
a shell contact piece that contacts the contact-point part of the plurality of elastic spring members is formed on the electrically-conductive shell of the second connector; and
the shell contact piece is formed so as to have a shape extending so as to rise from the wiring board and then bent back toward the wiring board.

9. The electric connector device according to claim 8 , wherein
the plurality of elastic spring members are disposed to form a row, and
the shell contact piece is continuously extending along an arrangement direction of the plurality of elastic spring members.

10. The electric connector according to claim 2 , wherein
the electrically-conductive cover member and the mating retaining member are composed of mutually different members; and
the electrically-conductive cover member is coupled to the mating retaining member via a mechanical fixation plates.

11. The electric connector according to claim 10 , wherein
the mating retaining member is formed by a rod-shaped member having a circular cross section or a rectangular cross section.

12. The electric connector according to claim 10 , wherein
the mechanical fixation plates include a swage fixation piece disposed to be opposed so as to sandwich the mating retaining member.

13. The electric connector according to claim 2 , wherein
