Description

Technical Field

[0001] The utility model relates to a cable connector provided with an anti-dropping structure, belonging to the technical field of cable connectors. Background Art

[0002] Cable connectors are mainly suitable for signal transmission between various digital program-controlled switches in transmission equipment bureaus, internal connections of optoelectronic transmission equipment and distribution frames, and are used to transmit data, audio, video and other communication equipment. The sheath is made of flame-retardant material with a high safety factor. It is produced using advanced technology to ensure that the cable has good flame retardancy and uniformity. Multi-core cables make rack laying more convenient.

[0003] The existing patent number is CN220914676U, which is a high-voltage connector plug with an anti-slip structure. In this device, when the high-voltage connector plug body is inserted into the high-voltage connector body, the two plastic plug plates can pass through the two anti-slip frames respectively, and then the two ends of the limiting component are respectively inserted into the two anti-slip frames and attached to the two plastic plug plates respectively, so that the two plastic plug plates cannot be pulled out from the two anti-slip frames, and the high-voltage connector plug body cannot be pulled out from the high-voltage connector body, thereby realizing the anti-slip function of the plug and improving the circuit connection stability. However, when this device is used, although the plastic plug plate provided in it can pass through the anti-slip frame, the toughness of the plastic plug plate is limited and it is easy to break, thereby affecting the stability of use. At the same time, the plastic plug plate can only be limited after the limiting bolt is used to limit the connection frame, which affects the convenience of disassembly and assembly of the connector plug; and in this device, no fastening anti-slip structure is provided for the cable, thereby easily causing the cable sleeve to detach from the connector plug during use and exposing the internal cable core to the outside, thereby affecting the safety of the cable.
