A common ground connecting member is used for the coaxial cable, and the ground connecting member is electrically connected to the ground contact. The electrical connection of the ground conductors of the plurality of coaxial cables by the ground connection member is performed, for example, by causing the plurality of coaxial cables to have a state in which portions where the ground conductors are exposed are arranged in a specific direction. The plurality of ground conductors arranged and arranged by the above are easily performed by commonly connecting and connecting ground connecting members extending in a specific direction. On the other hand, the following techniques are conventionally used to electrically connect the ground connecting member that connects the ground conductors of each of the plurality of coaxial cables to the ground contact.

  In one of the conventional methods of electrically connecting the ground connection member to the ground contact, the ground connection member is provided with a connection terminal portion protruding therefrom, and the connection terminal portion and the ground contact are aligned. As a result, the connection terminal portion and the ground contact are electrically connected (see, for example, Patent Document 1).

JP 2007-157594 A (4th to 5th pages, FIGS. 4 to 7) Japanese Patent Laying-Open No. 2008-97875 (Pages 5-8, FIGS. 2-5, 7)

  As shown in the above-mentioned Patent Document 1, a connection terminal portion protruding from the center portion in the arrangement direction of the plurality of signal contacts in the ground connection member is formed, and the connection terminal portion is fixed to the ground contact by soldering.
