A kind of ground connection switching wire clamp, it includes the ground connection body, and said ground connection body-fixed which is provided with the ground connection section on the lead-in wire of power equipment, and earth rod is sandwiched in said ground connection section place.
Therein among embodiment; Said ground connection body includes first canned paragraph, first that connects successively and connects arc, first linkage section, transition arcs, second linkage section, the second connection arc and second canned paragraph; Said ground connection section is the said second connection arc, through fixed structure said first canned paragraph and said second canned paragraph is fixed on the said lead-in wire.
The gabarit of said ground connection body is streamlined, has strengthened the intensity of said ground connection body, and installation, easy to use.
Therein among embodiment, the arc of the contact-making surface that said first canned paragraph and said second canned paragraph contact with said lead-in wire for cooperating with said lead-in wire.Guarantee that said first canned paragraph and said second canned paragraph can closely contact with lead-in wire.
Therein among embodiment, said first connect arc radian greater than said second connect arc radian.The second less connection arc of radian is convenient to that earth rod is sandwiched in said second and is connected the arc place.
Therein among embodiment; Said fixed structure includes U bolt and pressing plate; Said U bolt is placed in the periphery of said first canned paragraph and said lead-in wire and said pressing plate and fixing is passed at the two ends of said U bolt, or said U bolt is placed in the periphery of said second canned paragraph and said lead-in wire and said pressing plate and fixing is passed at the two ends of said U bolt.
Among embodiment, the material of said ground connection body is an aluminium alloy therein.
Among embodiment, the material of said fixed structure is a stainless steel therein.
The utility model compared with prior art has following beneficial effect:
The utility model ground connection patchcord ground connection is easy to operate, and anti-corrosive properties, conductivity are good, and connects fixing reliably, has saved the operating time, has improved operating efficiency.

Embodiment
Like Fig. 1 and shown in Figure 2, the utility model ground connection switching wire clamp, it includes ground connection body 11, and said ground connection body 11 is fixed on the lead-in wire 20 of power equipment.In this preferred embodiment, said ground connection patchcord is located between transmission of electricity working bus bar 100 and the lightning protection device 200, and promptly said ground connection patchcord clamping is on the lead-in wire of said lightning protection device 200.
Like Fig. 1 and shown in Figure 3, said ground connection body 11 includes successively first canned paragraph 12, first that connects and connects arc 13, first linkage section 14, transition arcs 15, second linkage section 16, second and connect the arc 17 and second canned paragraph 18; Wherein, Said first connect arc 13, said first linkage section 14, said transition arcs 15, said second linkage section 16 and second connect arc 17 form one be similar to n shape structure; And said first canned paragraph 12 and said second canned paragraph 18 are located at the both sides of this n shape structure respectively, and through four fixed structures said first canned paragraph 12 and said second canned paragraph 18 are fixed on the said lead-in wire 20.
As shown in Figure 4, can closely contact the arc of the contact-making surface that said first canned paragraph 12 and said second canned paragraph 18 contact with said lead-in wire 20 with said lead-in wire 20 for cooperating with said lead-in wire 20 in order to make said first canned paragraph 12 and said second canned paragraph 18.
Said first connects the radian of the radian of arc 13 greater than the said second connection arc 17.The second less connection arc 17 of radian is more convenient for that earth rod is sandwiched in said second and is connected arc 17 places.
Said fixed structure includes U bolt 30 and pressing plate 31; 31 are provided with two fixing holes on the said pressing plate; The two ends that said U bolt 30 is placed in periphery and the said U bolt 30 of said first canned paragraph 12 and said lead-in wire 20 are passed the fixing hole on the said pressing plate 31 and are fixed through nut; The two ends that the other end, said U bolt 30 are placed in periphery and the said U bolt 30 of said second canned paragraph 18 and said lead-in wire 20 are passed the fixing hole on the said pressing plate 31 and are fixed through nut.
