A cable shield tunnel for an electrical device includes a ground bus and a floor shim, discrete from the ground bus, and coupled to a circuit card and forming a cable tunnel that receives an end of a cable. The ground bus includes an end wall extending along a first end of the cable tunnel, a first side wall extending from the end wall along a first side of the cable tunnel, and a second side wall extending from the end wall along a second side of the cable tunnel opposite the first side. The first and second side walls are configured to be coupled to the circuit card. The floor shim is provided at a second end of the cable tunnel opposite the first end and is positioned between the cable and the circuit card.

Provided is a connector module that is highly durable and that also allows easy position alignment with a connection target instrument while maintaining high shielding performance. The connector module includes a connector case and a connector inserted in the connector case. The connector includes a contact, a holder, a conductive tubular shell, a housing and a conductive shield case. The shield case includes a first member having an elastic portion and a second member in the form of a bottomed tube. The first member forms an elastic piece contactable with the second member. Fixing of the connector case to a main body case via a fastener member causes, in the connector, elastic deformation of the elastic piece, resulting in decrease in a gap between the first member and the second member, consequently in establishment of electrical connection between the first member and the second member.

A contact system comprises a ground cylinder, a shielding cylinder press-fit with the ground cylinder, and a contact ring disposed between the ground cylinder and the shielding cylinder. The contact ring includes a strip of electrically conductive material defining a plurality of projections on at least one longitudinal side. The projections electrically contact the ground cylinder and the shielding cylinder for establishing an electrically conductive connection therebetween.

An electrical receptacle connector includes a metallic shell, an insulated housing in the metallic shell, a plurality of terminals at the insulated housing, and a metallic plate. The terminals are arranged in two rows, and the metallic plate is at the insulated housing and between the terminals in the two rows. The metallic plate includes a first through hole, several second through holes, and several communication holes. By allowing that the communication holes to be in communication with the first through hole and the second through holes in the metallic plate, the molding efficiency for forming the tongue portion with the filling of the plastic materials can be increased.

An electrical connector assembly is applied to be disposed on a circuit board. The electrical connector assembly includes an electrical connector and a grounding metal member that is sleeved around an outer side of the electrical connector. The grounding metal member has a first surrounding segment and a second surrounding segment that outwardly extends from an end of the first surrounding segment. The second surrounding segment has a shielding portion being ring-shaped and a plurality of extension portions that extend from the shielding portion. The grounding metal member is configured to be connected to a grounding circuit of the circuit board through the shielding portion and the extension portions.

It is aimed to improve grounding performance. A connector device is provided with a plurality of first terminal units to be mounted on a first circuit board, a plurality of second terminal units to be mounted on a second circuit board and a plurality of movable terminal units. The first terminal unit includes a first outer conductor surrounding a first inner conductor. The second terminal unit includes a second outer conductor surrounding a second inner conductor. The movable terminal unit includes a movable outer conductor surrounding a movable inner conductor. The movable terminal unit is swingable with the second terminal unit as a fulcrum. A tip part of the movable terminal unit is connectable to the first terminal unit. The plurality of movable outer conductors are electrically conductively connected via an alignment member serving as a connecting member.

A connector includes a connector housing and a shield shell. A terminal electrically connected to an end part of a wire is arranged inside the connector housing. The connector housing includes an inserting portion to be inserted into a mounting hole provided in a conductive case for accommodating an inverter and an outer arrangement portion integral with the inserting portion and to be arranged outside the case. The shield shell includes a tubular covering portion for covering an outer periphery of the outer arrangement portion and is electrically connected to the case. A shield-side sealing member seals between an outer-peripheral surface of the outer arrangement portion and an inner-peripheral surface of the covering portion. The outer-peripheral surface of the outer arrangement portion has a second intrusion suppressing groove provided over the entire outer periphery of the outer arrangement portion between the shield-side sealing member and the inserting portion.
