This application provides a lead module. The lead module includes a plurality of lead pairs and two shielding pieces, and the two shielding pieces each are made of a conductive material and are located parallel to each other on two sides of the plurality of lead pairs. Therefore, a ground wire or a shielding element may no longer be disposed between the two shielding pieces in the lead module of this application and between parts that are of adjacent lead pairs and that correspond to a body part of a lead, and the lead module uses the two shielding pieces as the ground wire and the shielding element. Therefore, crosstalk between the lead pairs for signal transmission is effectively reduced with a simple structure. This application further provides an electrical connector including the lead module and a connector component including the electrical connector.

In various embodiments, compact connector designs may be provided that have reduced board pitch (e.g., 1.80 mm, 1.50 mm, 1.27 mm, etc.), but are still capable of accommodating large electrical conductors (e.g., 1.4 mm, 1.1 mm, 0.9 mm, etc.). In this manner, PCB footprint may be reduced (e.g., by 50% when a staggered connector configuration is used), while adequate current carrying capacity may be maintained (e.g., 2 A, 3 A, 4 A, etc.). Additionally, or alternatively, one or more other advantages may be achieved, such as ruggedness (e.g., vibration endurance), error proofing, configuration flexibility, ease of manufacturing, ease of assembly, and/or lowered costs.

A plug connector of an electrical plug connection, the electrical plug connection including a mating connector to which the plug connector can be plugged in a plug-in direction. The plug connector has a housing and electrical plug contacts, which are arranged at least partially in the housing and are arranged side by side in a series direction. A first housing wall of the housing, which is arranged parallel to a plane spanned by the plug-in direction and the series direction, adjoins a second housing wall. The normal of the second housing wall points approximately in the plug-in direction and is arranged at an angle to the first housing wall. A third housing wall adjoins the second housing wall. Some of the housing walls may include fastening elements formed as grooves or recesses by which functional elements, such as latches or coding elements, may be attached to the housing.

A cable assembly includes a first cable and a second cable that is arranged co-axial to the first cable. Proximal ends of the first and second cables are provided with a connector assembly. The connector assembly from each proximal end is adapted to connect with one another, or a pair of receptacle ports located within a PCB, the PCB being disposed alongside the co-axially arranged first and second cables.

An electronic device connection system has a cable, a cable connector, and an electronic device. The electronic device has a socket. When the cable connector is mounted through the socket, the cable is electrically connected to the electronic device. The cable connector has a casing, a resilient latch, and a pulling member. The casing forms a protrusion and a first engaged opening. The resilient latch forms a hooked opening and a first hook. The protrusion can be engaged in the hooked opening, and the first hook can be engaged in the first engaged opening so the resilient latch is firmly fixed on the casing. Thus, the resilient latch may not be separated from the casing when a user pulls the pulling member, which ensures that the casing will be detached from the socket when the pulling member is pulled.

Provided is a housing including a bottom wall, a front-end wall, side walls, and a mating space. Each of the side walls includes a locking protrusion configured to engage with a counterpart locking protrusion locking protrusion of a counterpart housing when the counterpart housing is inserted into the mating space. Each of the side walls also includes an auxiliary-metal-fixture mounting portion configured to be loaded with an auxiliary metal fixture having a bottom end that is to be fixed to a surface of a board. The terminal is configured to be loaded in the front-end wall, and includes a connection part having a bottom end that is to be fixed to the surface of the board. The bottom wall has a surface facing the surface of the board, slanted surfaces are formed respectively on the left side edge and the right side edge of the surface of the bottom wall so that each slanted surface extends, in the front-to-rear direction of the sidewall, towards the outer side of the housing with a gradually widening gap with the surface of the board.

A receptacle connector 20 includes a housing 200 in which a recess 203 for housing a plug connector 30 is formed on a side opposite to a surface mounted on a substrate of the housing, a required number of contacts 220 arranged between end portions of the housing 200, and reinforcement metal fittings 230 each of which is provided on one of the end portions of the housing 200. The reinforcement metal fitting 230 has a cantilever resilient piece 235 that extends in the arrangement direction of the contacts 220, and a contact piece 236 that extends from a free end portion of the cantilever resilient piece 235 and comes into contact with the plug connector 30 when the receptacle connector 20 and the plug connector 30 are fitted to each other.

The present invention provides an electrical connector, cables, an insulation sleeve, a latch member, and a fastener. One end of the electrical connector is provided with a coupling portion, and wiring holes are defined on the other end of the electrical connector opposite to the coupling portion. The cables are inserted in the wiring holes respectively. The insulation sleeve covers the junction of the electrical connector and each of the cables, and the coupling portion protrudes out of the insulation sleeve. The latch member is disposed corresponding to one side of the electrical connector. The fastener is disposed corresponding to the other side of the electrical connector.

An electrical connector having a housing having a pin plate holder and a pin block holder. The pin block holder has a pin block holder stabilizing section. The pin plate holder has a pin plate holder stabilizing portion. With the pin block holder and the pin plate holder fully mated, the pin block holder stabilizing section engages the pin plate holder stabilizing portion to prevent the movement of the pin plate holder relative to the pin block holder in multiple directions.

An arc prevention system including a jack having a receptacle, with the receptacle having an upper wall, a bottom wall, two opposing side walls and a back wall between the two opposing side walls, a sensor unit positioned on the back wall of the receptacle, where the sensor unit is positioned on the back wall of the receptacle such that the sensor unit engages a plug inserted into the receptacle.
