摘要： 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.

摘要： An electrical connector includes an insulating body and multiple terminals accommodated in the insulating body. Each terminal has a base portion, a strip connecting portion extending upward from the base portion to be connected to a strip, and an elastic arm extending from the base portion. The elastic arm has a first tearing edge torn from the strip connecting portion, a second tearing edge torn from the strip, and a blanking edge blanked from the strip. The second tearing edge or the blanking edge has a dividing point. When each terminal is connected to the strip and expanded in a same vertical plane, the dividing point and a top point of the first tearing edge are vertically aligned. After the elastic arm is formed by bending, the dividing point and the first tearing edge are both located at a back side of the strip connecting portion.

摘要： An electrical connector includes: an insulating body provided with multiple accommodating holes running vertically therethrough, and multiple terminals correspondingly accommodated in the accommodating holes. Each accommodating hole has two protruding portions. Each terminal includes a main body portion. Two upper elastic arms are formed by bending upward and extending from left and right sides of the main body portion. Each upper elastic arm extends backward to form an upper abutting portion. A strip connecting portion extends upward from the main body portion to be connected to a strip. The strip connecting portion is located between the two upper elastic arms. Each of the left and right sides of the main body portion is provided with a position limiting portion protruding outward. The position limiting portion is located below the protruding portion. The position limiting portion and a corresponding upper elastic arm overlap along a vertical direction.

摘要： An electrical connection device includes an electronic component and a docking component. The electronic component includes a first conductor. The first conductor has a first section and a second section extending forward from the first section. The second section has a contact portion. A width of the contact portion in an extending direction of the second section gradually decreases. The docking component includes a second conductor conductively connected to the first conductor to transmit a high-frequency signal. The contact portion abuts the second conductor. The first section is located behind the second conductor. Thus, the cross-sectional area of the abutting location of the contact portion and the second conductor gradually decreases in the extending direction of the second section. That is, the cross-sectional area of the abutting location of the contact portion and the second conductor gradually decreases relative to the cross-sectional area of the first section.

摘要： A cable apparatus includes a circuit board having ground and signal pads, an insulating body in front of the circuit board, a pair of differential signal terminals retained in the insulating body, a cable located in front of the insulating body, and a shielding shell fixed to the insulating body. One ground pad is provided on each of two sides of adjacent two signal pads. Each terminal has an elastic portion extending out of the insulating body and conducting the signal pad, and a contacting portion exposed on a surface of the insulating body. The cable has two cable cores connected to the contacting portions, two insulation layers respectively wrapping the cable cores, and a shielding layer wrapping the insulation layers. The shielding shell has one end covering the contacting portions and conducting the shielding layer, and the other end covering the elastic portions and connected to the ground pads.

摘要： An electrical connector includes two adjacent terminal groups in a front-rear direction, including a front terminal group and a rear terminal group. Each terminal group includes a ground terminal and a signal terminal. The ground terminal has a first base portion and a first elastic arm. The first elastic arm includes two extending arms and a through slot formed therebetween. The signal terminal has a second base portion and a second elastic arm. The first elastic arm and the second elastic arm are used to be electrically connected to a mating member. In a same terminal group, the signal terminal is located in front of the first base portion, and the second elastic arm runs through the through slot. The mating member presses on the first elastic arm. The first elastic arm of the ground terminal of the rear terminal group abuts the ground terminal of the front terminal group.

摘要： 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.
