Abstract

A fiber optics cable waveguide connector for fiber optics cables having an outer casing, a strain relief element, an optical inner casing and an optical waveguide includes a clamping nut having a thread, an outer casing clamping device engageable with the outer casing, an inner sleeve, a strain relief element clamping device engageable with the strain relief element, an optical waveguide clamping device engageable with the optical waveguide, a press-on sleeve having a thread for releasably securing the press-on sleeve and the clamping nut together and for providing a clamping force when the clamping nut and the press-on sleeve are screwed together, a ferrule connected to the press-on sleeve, and a union nut connected to the ferrule. The clamping force arising from the fastening of the clamping nut to the press-on sleeve causes the outer casing clamping device to engage the outer casing, the strain relief element clamping device to engage the strain relief element, and the optical waveguide clamping device to engage the waveguide. Also, the clamping force releasably connects the clamping nut, the outer casing clamping device, the inner sleeve, the strain relief element clamping device, the optical waveguide clamping device, the press-on sleeve, the ferrule and the union nut together to each other.

Dependent claims

A connector for fiber optics cable with an outer casing, a strain relief element, an optical inner casing and an optical waveguide, the connector comprising:

a clamping nut having a thread;
an outer casing clamping device engageable with an outer casing of the fiber optics cable;
an inner sleeve;
a strain relief element clamping device engageable with a strain relief element of the fiber optics cable;
an optical waveguide clamping device engageable with an optical waveguide of the fiber optics cable;
a press-on sleeve having a thread for releasably securing said press-on sleeve and said clamping nut together and for providing a clamping force when said clamping nut and said press-on sleeve are screwed together;
a ferrule connected to said press-on sleeve;
and
a union nut connected to said ferrule,
the clamping force provided when said clamping nut and said press-on sleeve are screwed together causing said outer casing clamping device to engage the outer casing of the fiber optics cable, said strain relief element clamping device to engage the strain relief element of the fiber optics cable, and said optical waveguide clamping device to engage the optical waveguide of the fiber optics cable, and the clamping force releasably connecting said clamping nut, said outer casing clamping device, said inner sleeve, said strain relief element clamping device, said optical waveguide clamping device, said press-on sleeve, said ferrule and said union nut together.
