A plurality of contacts 18 arranged in the insulating housing 14, each having an insulating housing 14, a contact connecting portion 19 disposed on the fitting portion 17, and a cable connecting portion 20 connected to the coaxial cable 12; The projections 23 of the conductive shell 15 are provided with the conductive shell 15 mounted on the insulating housing 14 as an electromagnetic shielding function for the plurality of cable connection portions 20 of the contacts 18. , Forming a part of the fitting portion 17 provided in the insulating housing 14 and partially embedded in a part of the insulating housing 14 Therefore, the height of the entire connector device 11 can be reduced, and the fitting portion 17 provided in the insulating housing 14 has a small thickness. Even when the plate-like body is formed, the fitting portion 17 can be provided with a necessary strength by increasing the rigidity. As a result, a situation in which the fitting of the fitting portion 17 provided in the insulating housing 14 with the board-side connector device 13 is hindered is avoided, and the fitting connection of the connector device 11 to the board-side connector device 13 is appropriate. Will be done.

  Further, in the connector device 11, the through-hole 24 is formed in the protruding portion 23 of the conductive shell 15, and the through-hole 24 is blocked by the keel portion 25 that forms a part of the insulating housing 14. In addition, when the plurality of contacts 18, the first shell member 15A constituting the conductive shell 15 and the insulating housing 14 are integrally formed by insert molding, the insulating housing 14 is formed. Since the resin material flow path is formed, the integral formation by insert molding of the plurality of contacts 18, the first shell member 15 </ b> A constituting the conductive shell 15 and the insulating housing 14 forms the insulating housing 14. A proper flow of the molten resin material is obtained, for example, undesired in the insulating housing 14 Place in Moto generation of Eldora-in is suppressed, it is further enhanced strength of the fitting portion 17 provided in the insulating housing 14.

  The connector device according to the present invention as described above includes an insulating housing, a conductive shell mounted on the insulating housing, and a plurality of contacts arranged in the insulating housing, and the insulating housing is fitted with the mating connector device. A cable connecting portion to which a fitting portion to be placed in a combined state is provided and each of the plurality of contacts is connected to a fitting portion provided in the insulating housing and a coaxial cable is connected. And the contact connecting portion is configured to be contacted and connected to the mating contact in the mating connector device when the mating portion is in a mated state with the mating connector device. Even if the fitting portion provided on the insulating housing is formed into a thin plate-like body, the fitting portion is rigid. There as can be those equipped with the necessary strength is made to increase, but it can be widely applied to various electronic devices.
