A protective cover element for mounting on a contact blade of a blade contact of an electrical plug-and-socket connector projecting out of an insulating material, as well as to an electrical plug-and-socket connector with at least one such protective cover element.

An interposer includes a housing having a plurality of through-holes penetrating a first surface and a second surface and a signal contact pair composed of a pair of signal contacts. Each of the signal contacts includes a base portion press-fitted in one of the through-holes, a first contact beam extending from the base portion beyond the first surface, and a second contact beam extending from the base portion beyond the second surface. The pair of signal contacts are positioned adjacently to each other widthwise and are each asymmetrical with respect to a width direction. The signal contact pair has a plane-symmetrical shape with respect to the width direction.

When an upper contact part is not in contact with a signal pad, a lower contact part is not in contact with a short-circuiting pad, and when the upper contact part comes into contact with the signal pad and an elastic deformation part is elastically deformed, the lower contact part comes into contact with the short-circuiting pad. The current path length from the upper contact part to the lower contact part is shorter than the current path length from the upper contact part to a soldering part.

An electrical terminal includes a base, a first elastic arm and a second elastic arm formed side by side by extending upwardly from an upper end of the base, and a protruding portion. The first elastic arm has a mating portion, and the second elastic arm has a contact portion. The protruding portion protrudes and extends from a first side of the first elastic arm, and the first side of the first elastic arm is adjacent to the second elastic arm. A lower surface of the protruding portion has a contact surface overlapping with the contact portion in a vertical direction, such that the contact portion upwardly abuts the contact surface. When the chip module presses downwardly on the electrical terminal, the contact portion can move on the contact surface, such that the chip module does not need to press downwardly on the contact portion with a relatively large pressure.

According to an embodiment of the present disclosure, a connector for high-speed transmission to be fitted with an external counterpart connector includes a housing and a plurality of terminals. The housing has at least one or more slots. The plurality of terminals includes ground terminals and signal terminals are arranged in the slot along a first direction orthogonal to a fitting direction of the connector. Partition walls are provided between adjacent terminals in the slot, and a height of the partition walls between the ground terminals and the signal terminals in the fitting direction is lower than a height of other partition walls in the fitting direction.
