Circuit board mounted connector

1. A circuit board mounted connector, comprising:

an exterior shield shell, having a first face which is configured to be mounted on a circuit board to define an electromagnetic shielding space between the circuit board and the first face and a second face which is orthogonal to the first face and is opened for installation of a mating connector; and

a housing assembly, fitted in the exterior shield shell, so that the mating connector is connected thereto from one side of the exterior shield shell, and including:

a connecting terminal member, having one end which is a reed terminal configured to be connected to the circuit board and the other end which is a connector terminal configured to be connected to a connector terminal of the mating connector;

an interior housing, made of an insulation resin, and accommodating the connecting terminal member;

an interior shield shell, covering an outer circumference of the interior housing and the connecting terminal member, and configured to be electrically connected with a corresponding shield member of the mating connector; and

an exterior housing, made of an insulation resin, and accommodating and holding the interior shield shell,

wherein the exterior shield shell includes an assembly mounting opening through which the housing assembly is installed into the exterior shield shell, in the first face of the exterior shield shell.

2. The circuit board mounted connector according to claim 1 , further comprising:

a cutout portion, communicating between an inner surface and an outer surface of the exterior shield shell at a position which is visible from an outside of the exterior shield shell; and

an engagement confirmation projection, projected from an outer surface of the exterior housing, and fitted to the cutout portion in a state where the housing assembly is fitted in the exterior shield shell.

3. The circuit board mounted connector according to claim 1 , wherein

the assembly mounting opening is disposed apart from the second face,

a connection wall connecting faces of the exterior shield shell, which are orthogonal to both the first face and the second face, is provided at a part of the first face of the exterior shield shell connected to the second face, and

the connection wall performs as a housing supporting the mating connector.

4. The circuit board mounted connector according to claim 1 , wherein

spring pieces are projected from inner surfaces of faces of the exterior shield shell, the inner surfaces of faces being orthogonal to both the first face and the second face, at a positions closer to the second face so as to urge side faces of the mating connector inserted in the exterior shield shell,

faces of the exterior housing facing a part of the inner surfaces of the exterior shield where the spring pieces are projected are formed apart from the part of the inner surfaces so as not to contact the spring pieces.

5. The circuit board mounted connector according to claim 1 , further comprising:

elastic guide pieces, extended on inner surfaces of faces of the exterior shield shell, the inner surfaces of faces being orthogonal to both the first face and the second face, along an inserting direction of the exterior housing into the exterior shield shell, and urging opposite faces of the exterior housing inserted into the exterior shield shell so as to position the exterior housing at a center position in a widthwise direction of the exterior shield shell.
