The utility model discloses a breathable cable joint, which comprises a joint main body, a fastening nut and a locking nut; the connector main part is set body structure, and its middle part excircle is equipped with annular boss, and fastening nut and lock nut pass through threaded connection at the both ends that connect the main part, install on the annular boss and be used for making to connect the main part hole and carry out ventilative waterproof membrane, in the end of cable wears into the connector main part, connect the main part and pass through fastening nut to fix on corresponding installation basis, installed ventilative waterproof membrane in connecting the main part, can breathe the exhaust, adapt to the temperature variation of cable.

Furthermore, the one end that connects the main part and lock nut links to each other still is equipped with a plurality of elastic clamping jaw of axial extension and places in the rubber sleeve of circle in each elastic clamping jaw, can extrude each elastic clamping jaw to the center through screwing up lock nut, makes its inboard rubber sleeve shrink, and then cramps its inside cable, reaches fixed and sealed effect.

Further, the hole that connects the main part is the step hole, the inner of rubber sleeve supports and leans on the step face department that connects the main part hole, ensures the stable position of rubber sleeve, avoids shifting.

Furthermore, the outer end of the locking nut is provided with a cap body covering the outer end faces of the elastic clamping jaw and the rubber sleeve, the cap body is provided with a threading hole, and the aperture of the threading hole is not smaller than the inner diameter of the rubber sleeve; the inner surface of the cap body is a taper surface, chamfers matched with the inner surface of the cap body are arranged on the parts, in contact with the cap body, of the end portions of the elastic clamping jaws and the rubber sleeve, when the lock nut is screwed down, the taper surface is matched with the chamfers to extrude the elastic clamping jaws towards the center, and the comprehensive stress performance is good.

Further, still the cover is equipped with a waterproof gasket in the joint main part, waterproof gasket locates between fastening nut and the annular boss that connects the main part.

The utility model has the advantages that: the utility model discloses a ventilative cable joint increases ventilative water proof membrane in connecting the main part, then integrates integratively again to let cable joint not only concrete fastening waterproof function, possess again and breathe ventilative function.
