A connector lock structure includes an insulating body, a plurality of terminals, a shell, a locking assembly, a sliding board, a pressing element and an unlocking tool. The insulating body is molded around the plurality of the terminals. The shell surrounds the insulating body. The locking assembly includes at least one lacking groove, and at least one elastic arm formed in the at least one lacking groove. The at least one elastic arm has a hook structure. The hook structure is cooperated with a blocking groove of a docking connector. The pressing element is mounted in the insulating body. The sliding board is slidably mounted under the pressing element. One end of the pressing element has a locking portion. The locking portion has a keyhole. The unlocking tool is inserted in the keyhole.

Each of a feeding unit and a connector unit is provided with power supply ports and ground ports. In at least one of a connection of the power supply ports of the feeding unit and the power supply ports of the connector unit and a connection of the ground ports of the feeding unit and the ground ports of the connector unit, the number of parallel lines in at least a partial section is changed according to a length of the connection. In this way, a voltage drop between the feeding unit and the connector unit is adjusted.

An electrical connector includes an insulating body, a first terminal group having a signal terminal pair and a ground terminal arranged on one side of the signal terminal pair, each signal terminal having a tail portion, a contact portion, and a body portion, the body portion having a covering portion and a free portion exposed to air, wherein there is a first center distance between the contact portions of the signal terminal pair, there is a second center distance between the free portions, and there is a third center distance between the covering parts, and a second terminal group forming a first mating port with the first terminal group, wherein the second center distance is smaller than the first center distance, and the third center distance is greater than the second center distance.

A connection port module includes a fixed frame and a connection port. The fixed frame includes a main body portion, a first holding portion, and a second holding portion. The first holding portion is connected to one side of the main body portion and includes a first holding surface. The second holding portion is connected to the other side of the main body portion and includes a second holding surface. The first holding surface faces the second holding surface. The connection port is disposed in the fixed frame, and is located between the first holding surface and the second holding surface. A connector is adapted to be inserted into the connection port. The first holding surface and the second holding surface are adapted to abut against the connector to fix the connector on the fixed frame.

A plug-in connection box for vehicles has a socket and a return apparatus. The socket, is accessible from an access side and has an insertion direction. The socket is arranged in a pivot body, which is mounted in a movable manner in relation to a receptacle in such a way that the insertion direction of the socket is pivotable at an angle in all directions starting from a stationary state of the pivot body. The return apparatus is configured to return the pivot body to the stationary state.

A miniaturized paddle card assembly that provides high-speed, high-performance transmission. The paddle card has two or more rows of contact pads for mating with complementary conductors, two or more rows of terminals for cable termination, and alternating dielectric layers and metal layers. The two or more rows of terminals are disposed on respective metal layers. Such a configuration enables conductive traces electrically connecting corresponding contact pads and terminals to be substantially straight, and therefore reduces the lengths of the conductive traces. It is also reduced that the size of the paddle card in both a lateral direction parallel to the rows and a longitudinal direction perpendicular to the lateral direction, without changing the thickness of the paddle card. With the paddle card assembly provided herein, the integrity of the signals transmitted therethrough can be maintained and/or improved at higher speed.
