Abstract

Electromagnetic shielding about a part connected with a wiring substrate is easily and reliably carried out by a simple configuration without impairing productivity. A fixed shield plate provided at a shield shell member of an electric connector mounted on a wiring substrate is disposed to be opposed to a vicinity of a substrate connecting leg portion of a contact member. A movable shield plate covering a shell opening by a moving operation is provided. At least the substrate connecting leg portion of the contact member is covered from an outer side by fixed and movable shield plates, thereby well carrying out electromagnetic shielding (shielding) with respect to the part connected with the wiring substrate. Until the movable shield plate is subjected to the moving operation, the part connected with the wiring substrate can be checked well through the shell opening

Claims

1. An electric connector having a connector main body portion configured so as to be mated with a counterpart connector in a state in which the electric connector is mounted on a wiring substrate comprising,

a shield shell member attached to the connector main body portion in such a manner covering at least part of the connector main body portion,

a contact member attached to the connector main body portion and having a substrate connecting leg portion to be connected to an electrically-conductive path on the wiring substrate;

wherein a ground-connecting electrically-conductive path is formed on a surface part of the wiring substrate and at a vicinity position of a part to which the substrate connecting leg portion of the contact member is connected;

the shield shell member is provided with

a fixed shield plate rising from a surface of the wiring substrate and disposed to be opposed to a vicinity of the substrate connecting leg portion of the contact member in a state in which the fixed shield plate is solder-connected to the ground-connecting electrically-conductive path, and

a shell opening exposing the substrate connecting leg portion of the contact member toward a direction perpendicular to the surface of the wiring substrate;

a movable shield plate covering the shell opening is provided to be reciprocable between an unshielded position at which the shell opening is in an open state and a shielded position at which the shell opening is in a closed state; and

the movable shield plate is configured so as to contact the fixed shield plate when the movable shield plate is moved to the shielded position.

3. The electric connector according to claim 1, wherein

the movable shield plate is turnably provided at the counterpart connector or the first connector.

4. The electric connector according to claim 1, wherein

the movable shield plate is turnably provided at the shield shell member or the second connector.

5. The electric connector according to claim 1, wherein

a mating retaining member is turnably attached to the counterpart connector or the first connector;

in a case in which both of the connectors are mutually mated, the mating retaining member is configured to be turned from an unmated position to a mating working position so as to maintain a mutually mated state of both of the connectors; and

the mating retaining member is integrally provided with the movable shield plate.

6. The electric connector according to claim 1, wherein

the movable shield plate is provided with a plurality of plate-spring-shaped members that elastically contact the fixed shield plate.

7. The electric connector or the electric connector device according to claim 5, wherein

a lock portion that retains the mating retaining member at the mating working position.

2. An electric connector device having a first connector to which a terminal part of a signal transmission medium comes to be coupled and a second connector configured so as to be mated with the first connector in a state in which the second connector is mounted on a surface of a wiring substrate,

a connector main body portion of the second connector to which a second shield shell member covering at least part of the connector main body portion is attached, a second contact member attached to the second connector having a substrate connecting leg portion connected to an electrically-conducive path on the wiring substrate;

wherein a ground-connecting electrically-conductive path is formed on a surface part of the wiring substrate and at a vicinity position of a part to which the substrate connecting leg portion of the second contact member is connected;

the second shield shell member is provided with

a fixed shield plate rising from a surface of the wiring substrate and disposed to be opposed to a vicinity of the substrate connecting leg portion of the contact member in a state in which the fixed shield plate is solder-connected to the ground-connecting electrically-conductive path, and

a shell opening exposing the substrate connecting leg portion of the contact member toward a direction perpendicular to the surface of the wiring substrate;

the first connector or the second connector is provided with a movable shield plate covering the shell opening, the movable shield plate provided to be reciprocable between an unshielded position at which the shell opening is in an open state and a shielded position at which the shell opening is in a closed state; and

the movable shield plate is configured so as to contact the fixed shield plate when the movable shield plate is moved to the shielded position.
