Description

Cable sealing type joint structure

Technical Field

The utility model relates to the technical field of cable connectors, in particular to a cable sealing type connector structure.

Background

The cable connector is used for locking and fixing the incoming and outgoing lines, and plays a role in preventing water, dust and vibration. Its main function is to make the line smooth, make the cable keep sealing, and ensure the insulation grade of cable joint to make it run safely and reliably.

When the current cable joint is used, the current cable joint is spliced in the cable, a part of wires extend into the joint, the scattered wires are sealed through nuts sleeved on the outer wall of the cable, but the existing joint nuts slide on the cable, a gap is reserved between the existing joint nuts and the surface of the cable, and the sealing effect is poor.

Disclosure of utility model

The utility model aims to provide a cable sealing type joint structure, which aims to solve the problems that in the prior art, the existing joint nut slides on a cable, a gap is reserved between the existing joint nut and the surface of the cable, and the sealing effect is poor.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the cable comprises a connector body, a nut and a cable; the nut threaded connection is on the outer wall of joint body, cable one end is pegged graft on the joint body, the nut cover is established on the cable outer wall, nut outer wall connection has the extrusion helicoid, nut outer wall cover is equipped with first gasbag, extrusion helicoid one side with first gasbag contact, the nut inner wall is pegged graft there is the second gasbag, the intercommunication has the rubber tube between first gasbag and the second gasbag, second gasbag inner circle and cable contact.

Preferably, the outer wall of the nut is provided with a screw groove matched with the extrusion screw ring, and the extrusion screw ring is in threaded connection with the outer wall of the screw groove.

Preferably, the outer wall of the nut is provided with a mounting groove, and one end of the rubber tube is inserted into the mounting groove.

Preferably, the extrusion coil is hexagonal.

Compared with the prior art, the utility model has the beneficial effects that: the extrusion helicoid is rotated clockwise for the extrusion helicoid is close to first gasbag, and when the extrusion helicoid extrudeed first gasbag, inside gas is carried to the inside second gasbag that is located the nut inboard through the rubber tube of intercommunication to first gasbag, makes the inflation of second gasbag, seals the cable of grafting on the second gasbag inner race, prevents that water from entering into cable junction position, improves the life of cable.
