Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a dustproof and waterproof portable cable assembly comprises a cable 1, connectors 2 are welded to two ends of the cable 1 respectively, waterproof pipes 3 are wrapped at two ends of the cable 1, and one ends of the waterproof pipes 3 are connected with the connectors 2;

one end of the waterproof pipe 3 is provided with a circle of inserting ring 31, the outer wall of the inserting ring 31 is provided with external threads 311, the end of the waterproof pipe 3 positioned outside the inserting ring 31 is provided with a circle of first sealing ring 32, and the end of the waterproof pipe 3 positioned inside the inserting ring 31 is provided with a circle of second sealing ring 33;

the other end of the waterproof pipe 3 is provided with a circle of elastic upright column 34, and the inner sides of the elastic upright columns 34 are provided with limit teeth 341.

One end of the connector 2 is provided with a butt joint 21, the other end of the connector 2 is provided with an assembly joint 22, an insulating layer 24 is arranged inside the connector 2, a circle of slot 23 is arranged at the end of the connector 2 positioned outside the assembly joint 22, an internal thread 231 is arranged on the peripheral slot wall of the slot 23, and the size of the slot 23 is matched with the size of the insert ring 31.

In this embodiment, the connector, the cable, and the waterproof tube are assembled as follows:

firstly, sleeving a waterproof pipe on a cable, aligning an assembling interface of a connector with a guide core at the end part of the cable, coating a soldering tin point on the end part of the cable, inserting the guide core of the cable into an assembling butt joint, fitting the guide core with an insulating layer in the connector, slightly standing for several seconds and fixing by soldering tin, and then welding the connector and the end part of the cable;

at this time, the waterproof tube is moved to approach the connector end, the insert ring 31 is inserted into the slot 23 and screwed, at this time, the external thread and the internal thread are engaged with each other, and the first sealing ring 32 and the second sealing ring 33 are tightly attached to the end of the connector 2.
