DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to the field of electrical connectors and more particularly to shielded connectors.
BACKGROUND OF THE INVENTION
The installation of metal shield members on the outside surfaces of substantially box-shaped insulating housings of electrical connectors for the purpose of preventing electrical noise has been known in the past.
One example of a shielded electrical connector of this type is disclosed in Japanese Utility Model Application No. 5-34679. This disclosed electrical connector is a circuit board mounted connector; in this connector, a shield member constructed from metal plates is disposed so that this shield member is superimposed on four of the outside surfaces of the substantially box-shaped insulating housing.
In recent years, electrical connectors have tended to become more compact, and compactness has also been required in the shielded connectors described above. In addition, it is desirable that the shield members be disposed so that the outside surfaces of the connector are enveloped to the maximum extent possible. The object of the present invention is to provide a shielded connector that can easily be manufactured and assembled as a compact connector that has good shielding characteristics, and a method for manufacturing such a shielded connector.
In U.S. Pat. No. 5,281,169 is disclosed a boardmountable connector with right angle contacts and having a shield that comprises a forward shell part disposed across the housing mating face and the opposed side walls, and a rearward shell part that is disposed along the top housing wall and defines a continuous imperforate rear shield wall.
SUMMARY OF THE INVENTION
The present invention is characterized by the fact that in a shielded connector in which a substantially boxshaped insulating housing in which a mating face and a contact extension surface are positioned back-to-back is enveloped by a shielding means, the shielding means consists of a pair of substantially C-shaped shield members, each of which is positioned so that the shield member is superimposed on three of the six outside surfaces of the insulating housing, an opening used for mating with the mating connector is formed in a forward shield member, and a contact extension opening is formed on the rear shield member.
Preferably, the forward one of the substantially C-shape shield members includes a base wall and a pair of opposite walls, with the mating opening being formed in the base wall, and means used for engagement with the insulating housing being formed in the pair of opposite walls. Furthermore, the rear shield member includes a base wall and a pair of opposite walls, with the contact extension opening being formed in the base wall, and means used for engagement with the insulating housing being formed in the pair of opposite walls.
Preferably, furthermore, both of the shield members are formed by working metal plates. In this case, the forward shield member is formed by working a metal plate that is thicker than the metal plate used for the rear shield member, and the mating opening is formed inside a shroud that is formed by reduction working. Furthermore, the rear shield member has contact parts that can contact the forward shielding member.
Furthermore, the present invention is also characterized by the fact that in a method for manufacturing a shielded connector that has a substantially box-shaped insulating housing, the method includes a process in which contacts are fastened inside the insulating housing so that the contacts extend from the rear surface of the housing, a process in which a pair of substantially C-shaped shield members that respectively have an opening used for connector mating and a contact extension opening are mounted on the insulating housing from the mating face and the rear face of the insulating housing so that each of the shield members is superimposed on three different surfaces of the insulating housing, and a process in which the contacts extending from the contact extension opening are
