Description

General connecting device for preventing looseness of lead Technical Field The utility model relates to the technical field of wire connection, in particular to a general wire anti-loosening connecting device. Background In the existing wire connection technology, the conventional connection device generally has the problem that wires are easy to loosen. For example, the common clamping type connecting device only relies on a simple mechanical clamping mode to fix the wire, the device is not firm enough to fix the wire, the clamping force is easy to weaken with time or vibration, the wire is loose, and then the problems of poor electrical connection, signal transmission interruption and the like can be caused, so that the normal operation of equipment is affected. In addition, the conventional bolt-and-press connection device needs to fix the wire by tightening the bolt, but the bolt is easy to loose under the condition of repeated disassembly and assembly or vibration, so that the reliability of connection is reduced. In addition, some existing wire connection devices have poor versatility and are generally only capable of adapting to specific wire specifications. When wires of different specifications or types need to be connected, the whole connecting device is often required to be replaced or additional adapting parts are required to be used, so that the cost is increased, the working efficiency is reduced, and a plurality of inconveniences are brought to actual installation and maintenance work. Disclosure of utility model The utility model aims to provide a general connecting device for preventing loosening of a wire, which can overcome the defect that the wire is easy to loosen when the wire is fixed by the traditional connecting device.
