Shaft cable jack, be respectively BNC coaxial cable Q9 public plug, BNC coaxial cable Q9 female, BNC coaxial cable L9 public plug,
BNC coaxial cable L9 female;The live wire of three hole plugs 6, zero line, ground wire respectively with firewire binding post, zero line binding post, ground wire
Binding post pass through electric wire be connected, the live wire of holes plug, zero line be by electric wire respectively with firewire binding post, zero line binding post phase
Even;BNC coaxial cable Q9 public plug, BNC coaxial cable Q9 female, BNC coaxial cable L9 public plug, BNC coaxial cable L9
It is connected with earth terminal after the screen layer short circuit of female.
Described hiding groove is two, two hiding groove interval settings;Three hole plugs and holes plug are located at two respectively
In individual hiding groove.
The quantity of slide cover is more than one.
Also include holding wire, holding wire is connected to firewire binding post.
The present invention can achieve the power supply wiring and signal wiring being more applicable for complicated field test environment, can meet almost
The reality of work at all scenes needs, and wiring is simple and reliable, time saving and energy saving, can be greatly enhanced work efficiency.
Beneficial effects of the present invention:
(1) this device passes through three hole plugs and a holes plug, with firewire binding post, zero line binding post, ground wire
Binding post cooperation can achieve the combination in any collocation of field power supply wiring, substantially meets all field power supply wiring complicated and changeable
Situation needs.Wiring is easy to be reliable, convenient and practical.
(2)This device has a slidably slide cover on the upside of three hole plugs and holes plug recesses, in work people
When member is using a plug, slide cover blocks another plug completely, the effect play and protect user, preventing electric shock.
(3)This device adopts four BNC coaxial cable plugs, can achieve now with firewire binding post, earth terminal cooperation
The combination in any collocation of field stimulus wiring, substantially meets the needs of all scenes number of winning the confidence wiring condition.

Specific embodiment
As shown in figure 1, the present invention adopts modularized design, polymorphic type plug combination arrangement.On box body 1, front side is provided with
Three binding posts, are firewire binding post 2, zero line binding post 3, earth terminal 4 respectively.
As shown in Fig. 2 having embedded attaching plug and coaxial cable plug respectively in the left and right sides of box body 1.
The one of side of box body 1(Right flank)It is provided with two adjacent hiding grooves 5, in two hiding grooves 5 respectively
It is provided with three hole plugs 6 and a holes plug 7, three hole plugs 6 and holes plug 7 are all by the rotating bar of U-shaped(U-shaped
Rotating bar is prior art)It is connected with box body 1.
In also one slideway 16 of right flank, slideway 16 is located at hides groove 5 position in the outer part, is provided with cunning in slideway 16
Dynamic cover plate 15, slide cover 15 slides along slideway 16, covers in hiding groove 5.Slide cover 15 is a monoblock or two pieces, sliding
Dynamic cover plate 15 width sets as needed, can block three hole plugs 6 and the plug portion of holes plug 7 is just permissible, play anti-
The effect only got an electric shock.
As shown in figure 3, the opposite side of box body 1 has four coax jack, be respectively BNC coaxial cable Q9 public plug 8,
