The connection component 32 is connected to the top of the galvanized copper pipe 31. During use, the top of the connection component 32 is pulled out and connected to the grounding wire of the cable test equipment. After use, the grounding wire of the cable test equipment is disconnected and the top of the connection component 32 is pressed into the second box body 4.
[0033] Refer to Figures 3 to 5 The bottom plate is provided with a first through hole 11, and the first through hole 11 is located above the second box body 4.
[0034] Refer to Figures 3 to 5 The insulating layer 2 is provided with a second through hole 21, and the second through hole 21 is located above the first through hole 11.
[0035] Refer to Figures 3 to 5 On the ground of the second box body 4, there is a third through hole 41, and the galvanized copper pipe 31 is inserted into the third through hole 41.
[0036] Refer to Figures 3 to 5 The connection component 32 includes a housing 321, an inner core 322, and a terminal 323.
