Each cable connector assembly has a housing holding contacts terminated to corresponding cables. Each cable connector assembly has a holder mounted to the corresponding mounting location of the plate. The holder is mounted to the plate and removable from the plate through the rear opening at the rear of the plate.

A plug connector for mating with a receptacle connector which is provided with a groove at an upper surface thereof includes: an insulating body; and a locking elastic piece on the insulating body, wherein the insulating body includes a main body and a mating portion extending forward from the main body, a bottom of the mating portion protrudes downward to form a sinking portion, and the sinking portion is located entirely above the groove.

Disclosed is a board connector including a board connector body, conductive terminals of upper and lower rows inserted inside the board connector body and a docking housing wrapped outside the board connector body, wherein a front end of the board connector is used for docking with a cable connector, the docking housing including a top wall, a bottom wall and two side walls, a docking slot is provided between the top wall and a top surface of the board connector body, and the bottom wall is provided with a blocking element that protrudes downward. As compared with the prior art, interference may occur between a front end of a blocking element and a front end of a cable connector when the cable connector is reversely inserted, thereby preventing occurrence of a reverse inserting phenomenon.

A male strip connector having a support element made of insulating material that has a base area section, a retaining section protruding transversely therefrom and, on the side of the retaining section that is opposite the base area section, a fixing section, and having a plurality of contact pins that have a plug contact section and a connection contact section angled off with respect thereto, is described. The retaining section has a plurality of insertion openings, arranged next to one another, for inserting a plug contact section of a contact pin. The fixing section has a plurality of recesses for holding a respective connection contact section of a contact pin. The retaining section has a plurality, corresponding to the number of insertion openings, of fingers that are separated from one another by free spaces and in which the insertion openings are made.

The present disclosure disclosed a terminal assembly comprising a first terminal module and an electric conductive part. The first terminal module comprises a plurality of first ground terminals and a plurality of first signal terminals. At least one first signal terminal is provided between two adjacent first ground terminals. The electric conductive part is disposed on the first terminal module. The first signal terminal is closer to a surface of the electric conductive part than the first ground terminal. The electric conductive part is distancing from both the first signal terminal and the first ground terminal while the first signal terminals are closer to the electric conductive part than the first ground terminals, the electric conductive part and the ground terminal could surround the first signal terminal.

A single-row electrical wire structure includes a first circuit board and a wire assembly. A board-to-board connector is on the first circuit board. The first circuit board includes a first group of contacts arranged into a single row. A distance between center portions of adjacent two contacts of the first group of contacts forms a width. The wires assembly includes a plurality of high-speed signal pairs and at least one low-speed signal pair respectively connected to the first group of contacts. A first spacing between a contact in the first group of contacts corresponding to a first high-speed signal pair of the high-speed signal pairs and a contact in the first group of contacts corresponding to a second high-speed signal pair of the high-speed signal pairs adjacent to the first high-speed signal pair is at least equal to or greater than 2 times of the width.

According to one embodiment, a holder includes a recessed portion and including an opening, and includes a contact exposed from part of a bottom surface of the recessed portion. A lid covers the holder from the recessed portion side, makes a space in the recessed portion airtight in an engaged state in which the opening of the recessed portion is closed, and includes an elastic member pushing down a contained object contained in the recessed portion. And a lock mechanism forms the engaged state between the lid and the holder.

A stacked I/O connector with surface mountable tails and a printed circuit board (PCB) configured to receive the connector. The connector may avoid terminal deformations or scratches when the connector is mounted to the PCB. The PCB may include solder pads on a single surface or both surfaces. The sold pads may be configured for the tails of the connector to be attached with a surface mount soldering technique. As a result, the connector has high density and high speed, requires, requires a smaller mounting area on a PCB, relaxes the limitations in routing PCB traces, and reduces the electrical performance deterioration caused by PCB trace routing limitations. The connector may have row-oriented terminal subassemblies, holes in the connector housing and other features to facilitate reliable manufacture and operation of the connector.
