Description

Technical Field

[0001] The utility model relates to the technical field of cable protection sleeves, in particular to a fiber braided pultruded cable protection sleeve which can be quickly connected. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. Cable is a wire product used to transmit electromagnetic energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. When laying cables underground in conventional ways, protective casings must be arranged on crossing cables to prevent the cables from being crushed by passing vehicles.

[0003] For example, the Chinese patent with patent application number 202110379519.5 is a freeze-resistant and high-temperature resistant composite cable protective sleeve. This patent enables the cable to be suspended in the cable protective sleeve, avoiding direct contact with the protective sleeve. It has effective freeze-resistant and high-temperature resistant properties, while also ensuring the sealing and reliability of the interconnected cable protective sleeves.

[0004] However, the cable protection sleeve of the above patent is a hollow tube structure, and the cable is loaded and unloaded by plugging and pulling. The friction between the cable and the sleeve can easily cause wear of the cable insulation layer, and the loading and unloading operation is inconvenient, which seriously affects the operator's efficiency in repairing and replacing the protection sleeve and cable.
