Embodiment
The structural representation of general connecting rod is prevented for ground wire five as shown in Figure 1, it includes providing that what is linked together connects
Ground wire connection end 1 and earth terminal connection end, the ground wire connection end 1 is the piece for the prolate shape made by copper, specific to be grounded
Line connection end 1 is prolate cube shape, oblate angular length cube shape etc..Described earth terminal connection end is by cylindrical bar 2 and threaded rod 3
Integral type connects and composes, and the cylindrical bar 2 is a diameter of 14mm made by copper bar, and the threaded rod 3 is equally by copper
The a diameter of 14mm made bar.Described ground wire connection end 1 is connected with cylindrical bar 2.On described ground wire connection end 1
Two screw holes 4 are set, and spacing is 2.5 centimetres, a diameter of 0.6 centimetre of screw hole 4 between described two screw holes 4.Institute
Five anti-lockholes 5, the corresponding five anti-lock settings of diameter of five anti-lockholes 5 are set on the threaded rod 3 stated；It is provided with the threaded rod 3
Two nuts 6；Screw is equipped with the screw hole 4.
The length of the ground wire connection end and earth terminal connection end adds up to 15cm；Described cylindrical bar 2 compares screw thread
3 short one centimetres of bar, described ground wire connection end 1 is than 2 short one centimetres of cylindrical bar.
Install the utility model when, cylindrical bar 2 is penetrated in the hole of earth terminal upper steel plate first, ground wire connection end 1 with
Ground wire connection, by screw rod and nut, the fixed structures such as screw and nut can also be used, ground wire and ground wire are connected
The fastening of end 1, crimping make ground wire and the ground wire contact surface of connection end 1 smooth, contact relatively good；Then it is arranged on threaded rod 3
Two nuts 6, making two nuts 6, mutually counter-rotating compresses earth terminal steel plate simultaneously, fastening effect is played, because of the steel of earth terminal
