[0033] By setting up the protective component 3 including the wire insertion hole 301, the connecting frame 302, the fastening pad 303, the friction protrusion 304, the limit block 305 and the limit slot 306, during use, one end of the connecting wire is directly inserted into the wire insertion hole 301, and the connecting wire and the fastening pad 303 will contact each other due to friction. As the connecting wire is extended, the fastening pad 303 will be driven to move towards the bottom of the wire insertion hole 301. At this time, the limit block 305 at the bottom of the fastening pad 303 and the limit slot 306 at the bottom of the wire insertion hole 301 are stuck to each other, which plays a certain limiting role to prevent the connecting wire from falling off from the wire insertion hole 301 due to external force, and when it needs to be removed, the connecting wire can be directly pulled out with force, which is easy to operate and has a simple structure.
[0034] Specifically, Figure 2 As shown, a rotating groove 4 is provided at one end of the plug-in terminal body 1, a tightening bolt 5 is arranged inside the rotating groove 4, a through hole 6 is provided at the bottom of the rotating groove 4, the tightening bolt 5 passes through the through hole 6 and is connected to the inside of the plug-in hole 301, and a connecting spring piece 7 is provided inside the plug-in hole 301, and the connecting spring piece 7 is connected to one end of the tightening bolt 5.
[0035] Specifically, Figure 3As shown, a pressing groove 8 is provided on one side of the plug terminal body 1, and a pushing block 9 is provided inside the pressing groove 8. The pushing block 9 is made of rubber.
[0036] Specifically, Figure 3 As shown, a connection groove 10 is provided on one side of the plug-in terminal body 1, and one end of the connection groove 10 is completely through-set. A fixing block 11 is fixedly provided on one end of the plug-in terminal body 1, and the fixing block 11 corresponds to the connection groove 10.

[0038] Specifically, Figure 1 As shown, a mounting hole 13 is opened on one side of the plug-in terminal body 1. The mounting holes 13 are distributed at four corners of the surface of the plug-in terminal body 1. The plug-in terminal body 1 is used for installing an external protective cover.
[0039] Specifically, Figure 1 As shown, an elastic pad 14 is disposed on one side of the plug terminal body 1 . The elastic pad 14 is made of rubber. There are three groups of elastic pads 14 located on the surface of the connection frame 302 .
[0040] Specifically, Figure 1 As shown, one side of the plug-in terminal body 1 is provided with a chamfer, and a sign 15 is fixedly provided on the inclined surface of one side of the plug-in terminal body 1 .

[0042] By adopting the above technical solution, the problem that most existing protective devices have a relatively simple structure and the plug-in terminals are easily dislocated when the wires are pulled after being connected, thereby causing power outages, is solved.
[0043] Working principle: When the present application is in use, first insert one end of the connecting wire directly into the wire insertion hole 301. The connecting wire and the fastening pad 303 will contact each other due to friction. As the connecting wire is inserted, the fastening pad 303 will move relative to each other until it reaches the bottom of the wire insertion hole 301. At this time, the limiting block 305 at the bottom of the fastening pad 303 and the limiting slot 306 at the bottom of the wire insertion hole 301 will correspond to each other and play a certain limiting role to prevent the connecting wire from falling off from the wire insertion hole 301 due to external force. In the hole 301, the connecting wire and the fastening pad 303 will contact each other due to friction. As the connecting wire is extended, the fastening pad 303 will be driven to move against each other until the bottom of the wire insertion hole 301. At this time, the limiting block 305 at the bottom of the fastening pad 303 and the limiting slot 306 at the bottom of the wire insertion hole 301 are stuck to each other, which plays a certain limiting role to prevent the connecting wire from falling off from the wire insertion hole 301 due to external force, and the connecting wire can be directly pulled out with force when it needs to be removed.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
