As shown in fig. 1-4, embodiments of the present disclosure provide a cable connector assembly including a cable connector, a cable 10, and a compression member 14.

The cable connector defines a mounting channel 21 and includes a quick connector disposed at one end of the mounting channel 21.

As shown in fig. 1 and 4, the quick connector includes a female connector 1 and a male connector 18, which are matched with each other, one of the female connector 1 and the male connector 18 is located at one end of the installation channel 21, and the other of the female connector 1 and the male connector 18 is used for connecting with a device, which may be an underwater device or a road device. The cable connector assembly of the present application will be described with reference to the device as an underwater device, which may be an underwater inspection device or an underwater traveling mechanism, such as an underwater robot, an underwater tow vessel, or an underwater inspection vessel, depending on the application of the cable 10.

The cable 10 may be a kevlar cable 10, the kevlar cable 10 comprising a core 17, a tensile layer and a skin 20. The wire core 17 is positioned at the innermost part of the cable 10 and used for communication, the tensile layer is a filling layer and is preferably a Kevlar filling layer, the tensile layer wraps the wire core 17, all tensile force is borne in an evenly and fully distributed mode, the flexibility is good, and the wire core is not broken after being bent for multiple times; the surface layer 20 is the outer skin of the cable 10 and is located outside the tensile layer and the wire core 17, and can prevent water and abrasion. It is understood that the cable 10 in the present application may also be other types of cables 10 that include a core 17 and a tensile layer in addition to the kevlar cable 10. The following description will be given taking the cable 10 as the kevlar cable 10 as an example.

Optionally, a communication device is arranged on the underwater equipment, one of the female head 1 and the male head 18 is arranged at one end of the installation channel 21, and the other of the female head 1 and the male head 18 is connected with the communication equipment.
