Definitions

  • the present invention is related to an electrical connector, in particular to a cable connector.
  • a conventional cable connector includes a metal housing 5, a receptacle 6, a cable sleeve 7, and a cable 8.
  • the metal housing 5 includes a rear sleeve portion 50, an indentation ring portion 51, and a front sleeve portion 52 from rear to front.
  • the receptacle 6 is mounted in the front sleeve portion 52.
  • the cable sleeve 7 is a cylinder, is mounted in the rear sleeve portion 50, and has two clampers 70. The clampers 70 extend forward from a front end of the cable sleeve 7.
  • the cable 8 includes an outer insulation jacket 80, an outer conductor 81, two dielectric layers 82, and two inner conductors 83 from outside to inside.
  • a front section of the cable 8 exposes the two inner conductors 83, the two dielectric layers 82, and the outer conductor 81.
  • the cable sleeve 7 is first mounted around the outer conductor 81 exposed from the front section of the cable 8. Then, the outer conductor 81 is clamped by the two clampers 70 formed on the front end of the cable sleeve 7. A part of the outer conductor 81 protrudes from the cable sleeve 7 and the clampers 70 thereof. In this case, the outer conductor 81 is longer than the cable sleeve 7.
  • the part of the outer conductor 81 protruding from the cable sleeve 7 is folded outward and backward, is mounted around the cable sleeve 7, and is further mounted in the rear sleeve portion 50 of the metal housing 5.
  • a distal end 811 of the outer conductor 81 faces toward a rear opening of the rear sleeve portion 50.
  • the two exposed dielectric layers 82 are mounted through and are accommodated in the indentation ring portion 51.
  • the two exposed inner conductors 83 are mounted through the receptacle 6 and are fastened in the front sleeve portion 52 together.
  • the two clampers 70 need to be formed on the cable sleeve 7.
  • the outer conductor 81 needs to be folded outward and backward along an outside of the cable sleeve 7 mounted therein. Therefore, the structure of the conventional cable connector is complicated. The manufacturing process of the conventional cable connector is complicated which causes an increase of the cost of assembling. Thus, 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 inner metal shielding element of the cable connector in accordance with the present invention is mainly matchingly accommodated in the metal housing.
  • the inner metal shielding element is disposed outside the outer conductor and the two dielectric layers.
  • the outer surface of the inner metal shielding element is abutted against the inner surface of the metal housing.
  • the cable is fastened in the metal housing by the inner metal shielding element.

  • the outer conductor still has the capability of shielding the electromagnetic interference for the cable fastened in the metal housing.
  • the inner metal shielding element is only disposed outside the exposed front section of the cable and the inner metal shielding element. Then, the inner metal shielding element and the front section of the cable are mounted through the rear opening of the metal shell together.
