  • Patent number: 10886667
    Abstract: Electromagnetic shielding about both of electric connectors, which are in a mutually mated state, can be sufficiently carried out by a simple configuration. Shield wall portions composed of electrically-conductive members opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in multipolar shapes are provided; electromagnetic shielding functions with respect to the contact connecting portions in the respective electric connectors are obtained well by the respective shield wall portions; and, when both of the electric connectors are mated with each other, the shield wall portions are configured to be in an inner/outer double disposition relation in which they are opposed to each other and efficiently block the gaps between the shield wall portions and wiring boards so that sufficient EMI measures can be expected.

  • Publication number: 20200295497
    Abstract: In an electrical connector, a connecting portion has a first resin holding a lower contact with respect to an intermediate ground plate and a second resin holding an upper contact with respect to the intermediate ground plate and separate from the first resin. Also provided is a third resin covering the first resin and the second resin and separate from the first resin and the second resin. When the electrical connector is manufactured, deflection can be suppressed based on division into a step of forming the first resin and a step of forming the second resin and by means of a mold suppressing deflection of the upper contact and the lower contact.

  • Publication number: 20200194926
    Abstract: In an electric connector, a waterproof member having an internal waterproof portion and an external waterproof portion is provided in a main body portion. The internal waterproof portion and the external waterproof portion are integrated. Accordingly, the internal waterproof portion covers exposed portions of an upper contact and a lower contact and prevents water intrusion along the upper contact and the lower contact. In addition, the external waterproof portion prevents water intrusion between the electric connector and an inner wall of an accommodating space of an electronic device by surrounding the entire circumference of the main body portion. Since the internal waterproof portion and the external waterproof portion are integrated in this manner, both internal waterproofing and external waterproofing can be realized with the simple configuration of the single waterproof member in the electric connector.
