Definitions

  • the present invention is related to an electrical connector, more particularly to a cable connector.
  • a conventional cable connector includes an outer housing 6, a supporting sleeve 7, and a cable 8.
  • the outer housing 6 includes a first housing 60 and a second housing 61 mounted around the first housing 60.
  • the first housing 60 includes a sleeve portion 601 and an indentation ring portion 602 adjacent to the second housing 61 and concavely formed.
  • the cable 8 includes an outer insulation jacket, an outer conductor 80, an insulation layer 81, and an inner conductor 82 arranged in coaxial from outside to inside.
  • the inner conductor 82, the insulation layer 81, and the outer conductor 80 are exposed from a front section of the cable 8 in sequence.
  • the supporting sleeve 7 is mounted around the exposed outer conductor 80.
  • the outer conductor 80 is folded outward and backward along an outside of the supporting sleeve 7 since the outer conductor 80 is longer than the supporting sleeve 7.
  • the supporting sleeve 7 and the folded outer conductor 80 are mounted in the sleeve portion 601 of the first housing 60 together.
  • the exposed insulation layer 81 and the inner conductor 82 mounted therein are clamped by the indentation ring portion 602.
  • the first housing 60 and the second housing 61 are combined to form the outer housing 6 of the conventional cable connector. Therefore, the two-piece first and second housings 60 and 61 need to be manufactured separately and then assembled as the outer housing 6 by an additional step thereafter to complete the conventional cable connector. Thus, after the conventional cable connector has been plugged and unplugged many times, the first and second housings 60 and 61 may separate from each other to become invalid. Furthermore, the outer conductor 80 needs to be folded outward and backward along the outside of the supporting sleeve 7 to be firmly fastened in the sleeve portion 601 of the first housing 60.
  • the indentation ring portion 602 is required to be formed on the first housing 60 to further clamp the exposed insulation layer 81 and the inner conductor 82 mounted therein. Therefore, the assembling steps and the manufacturing process of the conventional cable connector are complicated and the conventional cable connector needs to be improved.
  • An objective of the present invention is to provide a cable connector.
  • the cable connector includes:
  • the cable connector of the present invention mainly applies the metal housing integrally formed.

  • the outer surface of the first inner metal shielding element is abutted against the inner surface of the main body.
  • the outer conductor of the cable is firmly fastened in the metal housing by being clamped by the first inner metal shielding element. Therefore, the cable is fastened in the metal housing in which the outer conductor does not need to be folded outward and backward along an outside of the first inner metal shielding element.
  • the first inner metal shielding element may shield electromagnetic interference.
  • the metal housing is integrally formed.
  • the metal housing does not separate to become invalid. Moreover, a structure for fastening the cable does not need to be additionally formed on the metal housing. Accordingly, the assembling steps and the manufacturing process of the cable connector in accordance with the present invention is effectively simplified and the efficiency in high-frequency signal transmission of the cable connector is enhanced.
