  In this type of connector, the terminal held by the housing has a contact portion facing the mating connector along the circuit surface of the circuit board, and a connection portion facing the circuit surface at a right angle to the connector surface, thereby forming an L-shape. There is no. A housing receives a contact portion of the terminal, a fitting portion forming a receiving recess opened forward to receive a corresponding fitting portion of a mating connector, and a terminal holding portion holding the terminal between the contact portion and the connection portion The bottom surface of the terminal holding portion is positioned on the circuit board of the circuit board, and the connection portion protruding from the bottom surface of the terminal holding portion is positioned to face the circuit surface, the terminal holding portion The connection part which protrudes from the bottom face of is connected to the said circuit board by solder etc.

  Such a connector is disclosed, for example, in Patent Document 1, and the connector of Patent Document 1 has a shield plate attached to the housing as seen in FIG. The shield plate is composed of an upper shield plate (designated by Patent Document 1 as upper shield 22a) and a lower shield plate (lower shield 34a), and the upper shield plate (upper shield 22a) is attached to the fitting portion of the connector The two elements of the connector side upper shield element 24a and the rear upper shield element 26a attached to the terminal holding portion are connected to form an L shape, and the lower shield plate (lower shield 34a) is attached to the fitting portion The two elements of the connector side lower shield element 36a and the (rear) lower shield element 38a attached to the terminal holder are connected to form an L shape.

  Thus, the connector of Patent Document 1 is provided with a shielding function by the upper shield 22a and the lower shield 34a attached to the housing.

  In Patent Document 1, the connector-side upper shield element 24a in the upper shield 22a and the connector-side lower shield element 36a in the lower shield 34a are desired to be formed as common elements in a flat plate shape.

Further, the lower shield contact portions 75A and 76A are pressed downward by the lower surface of the shield plate main body portion 111 of the lower shield plate 110, and the lower shield contact pieces 75 and 76 are elastically displaced downward. The elastic displacement of the upper shield contact pieces 61 and 62 and the lower shield contact pieces 75 and 76 permits the further insertion of the female connector 2. Insertion of the female connector 2 is performed until the front end face of the female connector 2 abuts on the bottom surface (surface perpendicular to the Y-axis direction) of the receiving recess 16 of the male connector 1, thereby completing the connector fitting process. It will be in the fitting state.

  In the connector fitted state, the elastically displaced state of the upper shield contact pieces 61 and 62 and the lower shield contact pieces 75 and 76 is maintained, and the upper shield contact pieces 61 and 62 are the shield plate main body portion 101 of the upper shield plate 100. The lower shield contact portions 75A and 76A contact the lower surface of the shield plate main body portion 111 of the lower shield plate 110 with a contact pressure, and can be electrically conducted.

  In the present embodiment, the shield plate of the female connector is attached to both of the pair of corresponding wall surfaces of the housing. Alternatively, when sufficient shielding performance can be secured, only one of the wall surfaces is provided. A shield plate may be attached.

  Also, in the present embodiment, the shield plate of the female connector is attached to the outer surface of the housing, but instead, the housing of the female connector has one receiving recess like the male connector of the present embodiment.
