Description

Technical Field

[0001] The present application relates to the technical field of cable heads, and in particular to a waterproof cable head. 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, and these connection points are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, 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.

[0003] With respect to the above-mentioned related technologies, the inventor believes that people generally use waterproof tape to repeatedly wrap the cable joints for waterproofing to ensure the insulation performance of the cable joints. However, after a period of time, the waterproof tape may fall off because it is not completely bound, and it needs to be repaired again. In addition, the tape is soft and easy to be broken, which will cause water to penetrate into it. Therefore, a waterproof cable head is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
