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 to mate with a counterpart connector in a state in which the electric connector is mounted on a wiring substrate, the electric connector comprising:

a shield shell member attached to the connector main body portion to cover at least part of the connector main body portion, and

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

wherein

a ground-connecting electrically-conductive path is formed on a surface of the wiring substrate and in a vicinity 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 that rises from the surface of the wiring substrate and has a surface that faces 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 that exposes the substrate connecting leg portion of the contact member toward a direction perpendicular to the surface of the wiring substrate;

a movable shield plate configured to cover the shell opening is provided that is 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 to contact the fixed shield plate when the movable shield plate is moved to the shielded position.

2. The electric connector according to claim 1, wherein

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

3. The electric connector according to claim 1, wherein

the movable shield plate is turnably provided at the shield shell member.

4. The electric connector according to claim 1, wherein

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

in a case in which both of the electric and counterpart connectors are mutually mated, the mating retaining member is configured to turn from an unmated position to a mating working position to maintain a mutually mated state of both of the electric and counterpart connectors; and

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

5. The electric connector according to claim 4, wherein further comprising:

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

6. The electric connector according to claim 1, wherein

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

7. The electric connector according to claim 1, wherein the surface of the fixed shield plate directly faces the substrate connecting leg portion of the contact member.

8. The electric connector according to claim 1, wherein the surface of the fixed shield plate faces the substrate connecting leg portion in a direction parallel to the surface of the wiring substrate.

9. An electric connector device, comprising:

a first connector to which a terminal part of a signal transmission medium is coupled, and

a second connector configured to mate with the first connector in a state in which the second connector is mounted on a surface of a wiring substrate, the second connector including a connector main body portion to which a shield shell member that covers at least part of the connector main body portion is attached, and including a contact member attached to the connector main body portion and 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 the surface of the wiring substrate and in a vicinity 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 that rises from the surface of the wiring substrate and has a surface that faces 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 that exposes 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 configured to cover the shell opening, the movable shield plate being 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 to contact the fixed shield plate when the movable shield plate is moved to the shielded position.

10. The electric connector device according to claim 9, wherein

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

11. The electric connector device according to claim 9, wherein

the movable shield plate is turnably provided at the second connector.

12. The electric connector device according to claim 9, wherein

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

in a case in which both of the first and second connectors are mutually mated, the mating retaining member is configured to turn from an unmated position to a mating working position to maintain a mutually mated state of both of the first and second connectors; and

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

13. The electric connector device according to claim 9, wherein

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

14. The electric connector device according to claim 12, further comprising:

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

15. The electric connector device according to claim 9, wherein the surface of the fixed shield plate directly faces the substrate connecting leg portion of the contact member.

16. The electric connector device according to claim 9, wherein the surface of the fixed shield plate faces the substrate connecting leg portion in a direction parallel to the surface of the wiring substrate.
