Description

Connector assembly

The present disclosure relates to a connector assembly, and more particularly, the present disclosure relates to a connector assembly with a terminal connector.

Chinese Patent No. 207868438 U discloses a technical means of using multiple shielding covers to improve the electrical performance of the system. In this publication, the shielding cover may include a holding piece engaged with a holding opening of a ground terminal plate and the shielding cover can thereby be installed in place by friction/interference fit. Or, alternatively, the shielding cover may be connected by a soldering or fusion welding operation or by using a conductive adhesive. In addition, the shielding cover is placed above a signal terminal pair including a first signal terminal and a second signal terminal so that the shielding cover is connected to the ground terminal plate. However, the shielding cover can only improve the crosstalk between adjacent signal terminal pairs, and cannot suppress the crosstalk between the biaxial cables.

The above "prior art" description only provides background technology, and does not acknowledge that the above "prior art" description reveals the subject of this disclosure, does not constitute the prior art of this disclosure, and any description of the above "prior art" Neither should be part of this case.

The embodiment of the present disclosure provides a connector assembly. The connector assembly includes a wire end connector. The wire end connector includes a wafer, a shielding plate and a biaxial cable. The sheet body includes a frame and a terminal group. The terminal group is configured to be supported in the frame. The terminal group includes a signal terminal pair and a ground plate. The ground plate is configured to provide a ground terminal on both sides of the signal terminal pair. The shield plate is configured to be connected to the ground plate. The shielding plate includes an opening through the shielding plate. The biaxial cable includes a pair of conductors and a grounding part. The pair of conductors extend through the opening of the shielding plate and are connected to the signal terminal pair. The grounding part is electrically connected to at least one of the shielding plate and the grounding plate.

In some embodiments, the shielding plate is arranged close to the connection point of the biaxial cable and the terminal set.

In some embodiments, the ground portion of the twinaxial cable is a metal shielding layer or a drain wire.

In some embodiments, the opening of the shielding plate is a closed hole, and the closed hole completely surrounds the biaxial cable.

In some embodiments, the shielding plate is located between the terminal set and the biaxial cable.

In some embodiments, the terminal set and the shielding plate are both located in the frame.

In some embodiments, the terminal set and the shielding plate are both set in the frame by means of insert mold.

In some embodiments, the shield plate includes a protrusion having a contact plane, and the contact plane abuts against the ground plate.

In some embodiments, the wire end connector is a first wire end connector, and the connector assembly further includes a second wire end connector and a base. The second wire end connector is parallel to the first wire end connector. The base is configured to assemble the first terminal connector and the second terminal connector.

In some embodiments, when the ground portion is electrically connected to the ground plate, the ground portion extends through the opening of the shield plate.

In some embodiments, the frame further includes at least one fixing portion for the ground plate, and the ground plate further includes at least one fixing hole penetrating the ground plate.
