An electrical connector includes an insertion slot, two terminal rows, a lossy member and at least one metal sheet. The two terminal rows are located at two sides of the insertion slot along the front-rear direction. Each terminal row includes a plurality of signal terminals and a plurality of ground terminals arranged side-by-side along a left-right direction. The metal sheet is provided between the lossy member and a corresponding terminal row. The lossy member runs through the metal sheet to be electrically coupled to the ground terminals. Along the front-rear direction, the metal sheet shields the signal terminals, such that the lossy member does not absorb (or reducing the portion of) the signal transmitted by each signal terminal toward a receiving end (such as a system), thereby optimizing the insertion loss of the electrical connector, and enhancing the SI of the electrical connector.

An electrical connector includes an insertion slot, a plurality of signal terminals and a plurality of ground terminals arranged side-by-side along a left-right direction, and a lossy member. Each ground terminal includes a grounding retaining portion. A grounding tail portion extends downward from the grounding retaining portion. A grounding elastic portion extends upward from the grounding retaining portion. The lossy member is electrically coupled to the ground terminals. The lossy member includes at least one extending portion passing upward beyond a bottom surface of the insertion slot and lower than the grounding contact portions of the ground terminals. In the front-rear direction, the extending portion islocated between the grounding elastic portion of a corresponding ground terminal and the insertion slot, such that the capacitive coupling of the grounding elastic portion is increased, further optimizing the crosstalk.

A conductive terminal and an electrical connector having the same are provided. The conductive terminal includes a base portion, an elastic arm formed by extending upward from an upper end of the base portion, and a conductive portion located below the base portion. The elastic arm includes a contact arm and a first arm and a second arm provided at an interval in a left-right direction. The first arm and the second arm are both located between the contact arm and the base portion. The contact arm has a contact portion. A maximum width of the second arm in the left-right direction is greater than a maximum width of the first arm in the left-right direction. A central line of the contact portion and a connecting location of the second arm and the base portion are located at left and right sides of a central line of the base portion.

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.

An electrical connector includes a plurality of insertion assemblies located between two adjacent ground terminals. Each insertion assembly includes a metal sheet and an insulating block including a wave absorbing material. The metal sheet is electrically connected to the two ground terminals. The metal sheet and the ground terminals are in plate shapes, and plate surfaces of the metal sheet and the ground terminals are parallel to each other. A thickness of the insulating block is greater than a thickness of each of the ground terminals. Two side surfaces of the insulating block abut against the insulating body. In the present invention, the stub generated by the transmission path between the two ground terminals is shorter, which has good high frequency characteristics, and the whole insertion assemblies may be more easily assembled and fixed to the insulating body.

An electrical connector, a conductive terminal and a forming method of a conductive portion of the conductive terminal. The conductive portion of the conductive terminal includes two elastic arms elastically abutting against a metal pad of a circuit board. Each elastic arm includes a first arm portion and a second arm portion separated along an up-down direction. A contact portion is formed at a tail end of the second arm portion, which does not form an open stub. Each contact portion has a tearing surface, such that a distance between the two contact portions of the two elastic arms is minimized. The two contact portions of the two elastic arms are provided to be staggered along the front-rear direction, and the two tearing surfaces of the two elastic arms are staggered along a front-rear direction, thus preventing the two elastic arms from scratching and colliding with each other.

A signal terminal and an electrical connector, and the electrical connector includes a plurality of terminal modules. Each terminal module includes two signal terminals. Each signal terminal includes a main body and an attaching portion attached to each other, a first elastic arm extending from the main body, and a second elastic arm extending from the attaching portion. The first elastic arm and the second elastic arm counteract the opposing sliding forces when contacting a circuit broad, thus forming dual signal transmission paths, and enhancing the transmission rates.

An electrical connector includes at least one electrical module, which includes an insulating body and a plurality of transmission modules. Each transmission module includes a terminal assembly and a cable assembly. Each terminal assembly includes two terminals and a shielding shell. Each terminal has a contact portion, a wire connecting portion and an intermediate portion. A first shielding portion of the shielding shell is provided outside the two wire connecting portions of the two terminals, and the first shielding portion is provided with an open area exposing the two wire connecting portions. A conductive sheet is electrically connected to the shielding shells of the terminal assemblies in a same row. The conductive sheet shields the open areas of the shielding shells in the same row. Each first shielding portion and the conductive sheet collectively form a shielding space and are surroundingly provided outside the two corresponding wire connecting portions.

An electrical connector includes a terminal unit. The terminal unit includes at least one signal terminal and a first ground terminal and a second terminal provided to be adjacent to the at least one signal terminal. A first grounding sheet includes a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion correspondingly connected to the first ground terminal and the second ground terminal at least partially overlap along a left-right direction. A distance between the first connecting portion and a closest signal terminal is not equal to a distance between the second connecting portion and a closest signal terminal, or an area of a surface of each of the first connecting portion and the second connecting portion adjacent to the signal terminal along the left-right direction is not equal. Thus, the superposition issue is prevented when resonant frequencies coincide.

An electrical connector includes a grounding member and a row of terminals arranged side-by-side in a left-right direction. The row of terminals include a signal terminal or a signal terminal group and two ground terminals respectively located at a left side and a right side of the signal terminal or the signal terminal group. No other terminal exists between each of the two ground terminals and the signal terminal or the signal terminal group. Each ground terminal includes a contact portion and a conductive portion. Each ground terminal has at least one contact location connected to the grounding member. A quantity of the contact location of the ground terminal at the left side of the signal terminal or the signal terminal group is different from a quantity of the contact location of the ground terminal at the right side of the signal terminal or the signal terminal group.
