Description

Technical Field

[0001] The utility model relates to the technical field of waterproof joints, in particular to a waterproof joint with multiple waterproof structures. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention.

[0003] For example, the Chinese utility model provides "a waterproof cable connector", and its announcement number is: CN216672565U, which includes a basic body, a clamping body, a first locking nut and a fixing nut. The basic body is a tubular structure. A first conical cavity is opened at one end connected to the basic body, and a second conical cavity is opened at the other end. The clamping body is arranged in the first conical cavity and the second conical cavity. The clamping body includes a tubular body, and conical wire bundle bodies are arranged at both ends of the tubular body. The conical wire bundle body includes a plurality of fins, and the plurality of fins are arranged around the end surface of the tubular body. The free ends of the plurality of fins are divided into an upper plate and a lower plate, and a wedge-shaped gap is left between the upper plate and the lower plate. The edges of the upper plate and the lower plate are connected by a plastic film, and the wedge-shaped gap sealed by the plastic film is filled with waterproof glue, which solves the problem that the existing waterproof cable connector is only sealed by rubber products such as sealing rings. After the equipment is used for a long time, the rubber ages and is still prone to water or oil leakage.
