  • Patent number: 11276965
    Abstract: An electrical connector includes an insulating body. Multiple terminals are provided on the insulating body, including two signal terminal pairs and two adjacent ground terminals located between the two signal terminal pairs. A metal shell is provided and covering outside the insulating body, and includes a neck portion extending backward from a top plate, and a first elastic arm, a second elastic arm and a third elastic arm formed by respectively extending backward from the neck portion. Each of the three elastic arms has a contact portion. The contact portions of two adjacent elastic arms are staggered to each other. A ground terminal is provided between two adjacent elastic arms. When the neck portion deviates toward different directions, each of the two ground terminals is in contact with the contact portion of at least one of the elastic arms.

  • Patent number: 10784606
    Abstract: An electrical connector is mounted downward on a circuit board to mate with a mating member. The electrical connector includes an insulating body having a front end surface, where the front end surface is backward concavely provided with a mating slot for the mating member to be inserted therein, and at least one ground terminal. Each ground terminal has a main body provided on the insulating body. A first elastic arm and a second elastic arm extend forward from the main body. The first elastic arm has a first contact portion in downward contact with an upper shielding member. The second elastic arm has a second contact portion in downward contact with the mating member. The first contact portion is located in front of the second contact portion. An acting force by the first elastic arm counteracts a supporting force by the circuit board, preventing the insulating body from deformation.
