  • Patent number: 11469533
    Abstract: 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.

    Abstract: 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.

  • Patent number: 11139604
    Abstract: 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.

  • Patent number: 10547139
    Abstract: 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.
