Under the action of the spring, even if the fixing nut 105 is slightly loose, the grounding wire 104 can still be tightly attached to one side of the fixing nut 105 under the action of the restoring elastic force of the spring.

[0033] The protection component 200 is disposed on the cable terminal 102 and includes a fixing member 201 , a protection member 202 and a positioning member 203 . The fixing member 201 is fixed to the surface of the cable terminal 102 , the protection member 202 is disposed on the fixing member 201 , and the positioning member 203 is located on the fixing member 201 .

[0034] The protective components 200 are all made of insulating materials. The fixing parts 201 are used to support the protective parts 202. The protective parts 202 are used to protect the grounding bolts 103, the ends of the grounding wires 104 and the fixing nuts 105. The positioning parts 203 are used to limit the fixing nuts 105 and the protective parts 202.

[0035] Specifically, the fixing member 201 includes a fixing ring 201a, a positioning piece 201b and a support rod 201c.

The support rod 201c is used to support the protective member 202.

[0037] Specifically, the protective member 202 includes a positioning sleeve 202a and a protective sleeve 202b. The positioning sleeve 202a slides on the surface of the fixing nut 105, and the protective sleeve 202b is sleeved on the surface of the positioning sleeve 202a.

[0038] The positioning sleeve 202 a is used to limit the fixing nut 105 , and the protective sleeve 202 b is used to protect the grounding bolt 103 , the end of the grounding wire 104 and the fixing nut 105 .

[0039] Specifically, the protective member 202 further includes a first support block 202c and a first slide bar 202d. The first support block 202c is fixed to the surface of the protective sleeve 202b, and the first slide bar 202d is fixed to one side of the first support block 202c.

[0040] There are two first support blocks 202c for fixedly supporting the first sliding rod 202d. The first sliding rod 202d supports the protective cover 202b by sliding in the support rod 201c.

[0041] Specifically, the protective member 202 further includes a second support block 202e and a second slide bar 202f. The second support block 202e is fixed to the surface of the protective sleeve 202b. The second slide bar 202f is fixed to one side of the second support block 202e. A slide groove U is provided in the support bar 201c.

[0042] There are two second support blocks 202e, which are used to provide fixed support for the second slide bar 202f. The surface of the second slide bar 202f is in close contact with the inner wall of the slide groove U. The opening of the slide groove U is positioned so that the first slide bar 202d can pass through, and the second slide bar 202f cannot slide out of the slide groove U. When the first slide bar 202d slides out of the slide groove U and the second slide bar 202f is located in the slide groove U, the protective cover 202b can be rotated so that the protective cover 202b will not hinder the inspection and maintenance of the docking location by the staff.

[0043] Example 2

[0044] Reference Figure 4 , Figure 5 and Figure 7 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0045] Specifically, the positioning member 203 includes a support frame 203a and a support shaft 203b. The support frame 203a is fixed to the surface of the protective sleeve 202b, and the support shaft 203b is fixed inside the support frame 203a.

[0046] The support frame 203 a is used to fix and support the support shaft 203 b , and the support shaft 203 b is used to support the positioning member 203 .

[0047] Specifically, the positioning member 203 further includes a pressure rod 203c and an insert block 203d. The pressure rod 203c is rotatably connected to the surface of the support shaft 203b, and the insert block 203d slides inside the pressure rod 203c.

[0048] The pressure rod 203c is used to limit the position of the insert block 203d, and the insert block 203d is used to limit the position of the positioning sleeve 202a.

[0049] Example 3

[0050] Reference Figure 2 , Figure 4 , Figure 5 and Figure 7 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0051] Specifically, the positioning member 203 further includes a first spring 203e, two ends of which are respectively fixed to the inner top wall of the pressure rod 203c and the inner bottom wall of the insert block 203d, and a slot V is provided on the surface of the positioning sleeve 202a.

[0052] The first spring 203e is in a compressed state. When the positioning sleeve 202a rotates, the reset elastic force of the first spring 203e allows the insert block 203d to be inserted into the slot V of the positioning sleeve 202a, thereby limiting the angle of the positioning sleeve 202a, thereby limiting the fixing nut 105 and preventing the fixing nut 105 from loosening.

[0053] Specifically, the positioning member 203 further includes a post 203f and a handle 203g. The post 203f slides in the support rod 201c, and the handle 203g is fixed to the top of the post 203f.

[0054] By pulling the handle 203g, the plug post 203f can be driven to move upward, thereby releasing the position restriction of the second sliding rod 202f by the plug post 203f.

[0055] Specifically, the positioning member 203 further includes a second spring 203h and a driving ring 203i. Two ends of the second spring 203h are respectively fixed to the inner wall of the support rod 201c and the top of the driving ring 203i. The driving ring 203i is fixed to the surface of the plug post 203f.

[0056] The second spring 203h is in a compressed state, and the driving ring 203i can be pushed by the return elastic force of the second spring 203h, so that the driving ring 203i drives the plug 203f to move downward, thereby limiting the second sliding rod 202f.

[0057] During use, when the docking location needs to be protected, the positioning sleeve 202a can be sleeved on the surface of the fixing nut 105, and then the handle 203g is pulled while the protective sleeve 202b is moved, so that the protective sleeve 202b is sleeved on the surface of the positioning sleeve 202a, and at the same time, the first slide bar 202d slides in the slide groove U. At this time, the support rod 201c squeezes the pressure rod 203c, so that the pressure rod 203c is attached to the top of the protective sleeve 202b. At this time, the plug block 203d is inserted into the protective sleeve 202b. As the protective sleeve 202b moves , the chamfer on one side of the positioning sleeve 202a can squeeze the plug block 203d, so that the plug block 203d shrinks into the pressure rod 203c until the plug block 203d is located on one side of the slot V, and the second slide bar 202f moves to the side of the plug column 203f. At this time, the handle 203g is released, and the return elastic force of the second spring 203h can push the drive ring 203i, so that the drive ring 203i drives the plug column 203f to move downward, thereby limiting the second slide bar 202f, thereby fixing the protective sleeve 202b.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
