This connector unit 1 is provided with a plurality of coupled sub connectors 10, wherein the sub-connectors 10 are each provided with a lower housing 20 and an upper cover 40, and the upper cover 40 is configured to be slidable between a main closed position and a provisional closed position and to be pivotable between the provisional closed position and an open position. One among the lower housing 20 and the upper cover 40 comprises: a pivoting permitted part 51A that permits pivoting when the upper cover 40 is at the provisional closed position; and a pivoting restriction part 51B that restricts pivoting when the upper cover 40 is at the main closed position. One sub connector 10A is provided with a movement restriction part 45 that restricts a slide movement of the upper cover 40 provided to another sub connector 10B from the main closed position to the provisional closed position.

A holding frame for a plug connector, for receiving contact inserts, includes: a main frame, which has a first side wall, a second side wall opposite the first side wall, a first end wall, and a second end wall opposite the first end wall, the first side wall, the second side wall, the first end wall, and the second end wall enclosing an interior of the main frame into which the contact inserts are insertable in an insertion direction; and multiple wall segments, each of which has a fastening region via which the contact inserts that are inserted into the interior of the main frame are holdable on the main frame. Each wall segment of the multiple wall segments are arranged on a receiving section formed on the first side wall or on the second side wall. Each receiving section has a slot-like cutout.

An insulation displacement contact (IDC) cluster includes a plurality of IDC cluster modular units each having a plurality of receptacles adjacent to one another in a row. Each of the receptacles receives an IDC terminal. A first IDC cluster modular unit of the IDC cluster modular units is coupled to a second IDC cluster modular unit of the IDC cluster modular units to form a modular structure by stacking and fastening together, arranging the receptacles of the IDC cluster modular units in parallel rows.

A cable connector includes an outer shell having a bore extending between a mating end and a cable end. The outer shell has latch pockets. The cable connector includes a shield received in the outer shell that divides the bore into chambers. The cable connector includes contact holders received in corresponding chambers. Each contact holder includes at least one contact channel and a deflectable latch having a latching head at a distal end of the latch configured to be received in the corresponding latch pocket of the outer shell to axially secure the contact holder in the outer shell. The latch has an interference bump at an inner end of the latch configured to engage the shield to press the latching head of the latch outward. The cable connector includes contacts received in corresponding contact channels of the corresponding contact holders.

A direct mate orthogonal connector for a high density of high speed signals. The connector may include right angle leadframe assemblies with signal conductive elements and ground shields held by a leadframe housing. The leadframe assemblies may each have signal mating ends extending from the signal conductive elements and ground mating ends extending from the ground shield. High frequency performance may be achieved with features on the leadframe housing and on the ground shield. The features may be simple to form yet ensure the positional relationship between the contacts points of the ground mating ends and the contact points of the signal mating ends to sustain forces generated during operating the connector to mate with another connector and/or mount to a board.

A modular plug connector having a holding frame having side walls which laterally delimit a receiving space, and at least one plug connector module which can be introduced into the receiving space. The side walls have a plurality of holding-frame-side guide elements and the at least one plug connector module has at least one plug-connector-module-side guide element. The at least one plug-connector-module-side guide element can be plugged into the holding-frame-side guide elements such that the plug connector module is positioned in the receiving space. The side walls have a latching structure and the plug connector module has at least one latching tongue which engages into the latching structure. The at least one plug connector module has at least one functional element with which functional element a functional contact to a functional element of a plug connector module of another plug connector can be established.
