An electrical connector includes an insulative housing, a number of conductive terminals affixed to the insulative housing, a shielding shell enclosing the insulative housing; and a sealer. The insulative housing includes a base portion and a tongue portion extending forwardly from the base portion. Each conductive terminal includes a contacting portion exposed to the tongue portion. The shielding shell includes a number of locking grooves penetrating rearward and a number of tubers and each sandwiched between two locking grooves. The sealer seals a rear end of the shielding shell. The sealer includes a number of tubers corresponded with the locking grooves of the shielding shell and a number of locking grooves receiving the tubers of the shielding shell.

An electrical connector includes: a contact module including an insulative housing and an upper and lower rows of contacts, the insulative housing having a rear base and a front tongue, the base having a pair of side latching walls; and a shielding shell enclosing the contact module, the shielding shell having a main part and a pair of side arms extending rearwardly from the main part, each side arm having an inserting portion and a soldering leg; wherein each inserting piece engages a corresponding side latching wall to prevent an associated soldering leg from moving outwardly.

A cable shield tunnel for an electrical device includes a ground bus and a floor shim, discrete from the ground bus, and coupled to a circuit card and forming a cable tunnel that receives an end of a cable. The ground bus includes an end wall extending along a first end of the cable tunnel, a first side wall extending from the end wall along a first side of the cable tunnel, and a second side wall extending from the end wall along a second side of the cable tunnel opposite the first side. The first and second side walls are configured to be coupled to the circuit card. The floor shim is provided at a second end of the cable tunnel opposite the first end and is positioned between the cable and the circuit card.

A connector includes a first layer having first and second communication channels, and a ground channel. The first and second communication channels form a first differential pair and transmit a differential signal. The ground channel separates the first differential pair from a next differential pair within the first layer. A surface of the ground channel nearest the first and second communication channels is selectively roughened to a particular roughness level to dampen crosstalk between the first differential pair and the next differential pair to a particular crosstalk level.

An electrical connector includes an insulative housing, a plurality of conductive terminals retained in the insulative housing and two grounding members. The insulative housing defines an upper sidewall, a lower sidewall and two end walls connected to both ends of the upper and lower sidewalls to form a mating cavity. Each grounding member defines a body portion fixed to the insulative housing and a plurality of contacting arms extending forward from the body portion. Each contacting arm defines a pair of wing portions located on both sides thereof, and the upper and lower sidewalls define a plurality of channels and a plurality of receiving slots. The contacting arms of the grounding member are running through the channels and projecting into the mating cavity, and the wing portions are abutted against the bottom surfaces of the receiving slots to form a pre-pressure to the contacting arms.
