  • Patent number: 7462078
    Abstract: A power connector includes a main body and a conductive contact. The main body has a front surface and a sidewall. The front surface defines a receiving cavity. The front of the sidewall defines at least one positioning hole communicating with the receiving cavity, and then a blocking wall is formed at the front of the positioning hole. The conductive contact is received in the receiving cavity of the main body and has a fixing portion, a base portion and connecting portions connecting the fixing and base portions. The fixing portion is formed by a rectangular board bending to form an arch structure. The front of the fixed portion is cut to form at least one cut portion with a free end at front and a connecting end connecting to the fixing portion at back. The cut portion bends outwards to form a blocking lump, the blocking lump engages with the positioning hole and is blocked by the blocking wall. Therefore, the conductive contact can be fastened firmly and securely.

  • Patent number: 7387532
    Abstract: A power connector includes a main body and a conductive contact. The main body has a front surface and a sidewall. The front surface defines a receiving cavity. The front of the sidewall defines a groove communicating with the receiving cavity at the top, then a propping beam is formed at the front of the groove. The propping beam defines a gap communicating with the receiving cavity. The gap communicates with the groove at back and communicates with the outside at front. The conductive contact is received in the receiving cavity of the main body, having a fixing portion, a base portion and connecting portions connecting the fixing and base portions. The fixing portion is formed an arch structure, then an opening end is formed at the top. A propping portion is projected from the fixing portion. The propping portion is secured in the groove by against the propping beam. Therefore, the conductive contact can be fastened firmly and securely.
