A housing holds a contact. A shield member is held in the housing and blocks electromagnetic waves, and the contact is arranged inside the shield member. The housing is provided with a ground spring mount portion, which is a portion to which the ground spring member is to be mounted. The ground spring member electrically connects the shield member and an external grounding member when the ground spring member is mounted to the ground spring mount portion.

Electrical connector

The coaxial connector is provided with a contact, an internal housing, a shell and an electromagnetic shield plate. The contact has a connecting portion which can connect with a mating side contact, and a crimping portion which crimps the central conductor. The internal housing has a contact receiving chamber opened at a rear end portion, and the connector is retained in the contact receiving chamber. The shell has a shell main body covering an external perimeter of the internal housing, and a cable clamp. The cable clamp fixes an end of the coaxial cable. The shell main body has a lock piece. A pair of slits is provided at both sides of the lock piece. The electromagnetic shield plate is disposed at an upper face of the internal housing, and has one piece which shields a portion of the pair of slits with respect to the internal housing.

Coaxial connector with electromagnetic shield

An electric connector includes an insulating body, wherein connection parts to be connected with counterpart connectors are arranged in the height direction, a conductive outer wall shell put on the body and having an opening on the front side, and a conductive inner wall shell for partitioning the connection parts. Both the ends, in the width direction, of the intermediate part of the inner wall shell are extended to fasten to the outer wall shell, and at least one end is formed into an approximately-U-shaped thrust-in part rising from the front side toward the rear side when seen in the width direction, and two top ends on the rear side of the thrust-in part are fastened into two slits formed in the outer wall shell. Thereby, the coupling strength between the outer and inner wall shells and the anti-prying strength against prying forces exerted by counterpart connectors are enhanced significantly, and the electric connector is reliably prevented from being damaged.
