In a further preferred embodiment, the change-over switch uses multicircuit switch to switch the corresponding entrance boat of connection
Insert and export air plug.
In a further preferred embodiment, several described outlet air plugs include at least one to connect current sample line with
Carry out the anti-open ended air plug of current sample.
In a further preferred embodiment, the cabinet is arranged in several described entrance air plugs and several outlet air plugs
On bottom surface
In a further preferred embodiment, several described outlet air plugs include 4 stitch air plugs, 6 stitch air plugs and 10 stitch
Air plug.
In a further preferred embodiment, the 6 stitch air plug is anti-open ended air plug.
The beneficial effects of the utility model are:
1, the cable access entrance air plug of external old switch is entered into cable connection box, then outer by outlet air plug access
Portion's pole-mounted switch case, so that old on-pole switch has telemetering, remote signalling and distant control function.
2, specific entrance air plug is connected by multicircuit switch selection and realizes that pole-mounted switch case passes through transfer box
It is connect with specific on-pole switch.
3, outlet air plug can be adapted to different cable connectors using the air plug of different stitch.
4, the bottom surface that cabinet is arranged in air plug had into stronger waterproof performance.
5, service without power-off is realized using anti-open ended air plug, does not have a power failure and replaces pole-mounted switch case, improve O&M water
It is flat.The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of cable of the utility model turns
Case is connect to be not limited to the embodiment.
Detailed description of the invention
Fig. 1 is the system block diagram of one preferred embodiment of the utility model.
Fig. 2 is the box structure diagram of one preferred embodiment of the utility model.
Specific embodiment
Embodiment, referring to shown in Fig. 1 to Fig. 2, a kind of cable connection box of the utility model, the cabinet is interior to be equipped with conversion
Switch, several entrance air plugs for being used to connect with on-pole switch and several outlets for being used to connect with pole-mounted switch case
Air plug, the both ends of the change-over switch can be separately connected several described entrance air plugs and several outlet air plugs and for switching
Corresponding entrance air plug and outlet air plug are gated, realizes that the signal between on-pole switch and pole-mounted switch case connects
It includes cabinet 10, in the cabinet 10 equipped with 4 road change-over switches 11, several are used to connect with on-pole switch
4 entrance air plugs 13 and several 3 outlet air plugs for being used to connect with pole-mounted switch case 20,4 road change-over switch
Both ends can be separately connected 4 entrance air plugs 13 and 3 outlet air plug and gate corresponding entrance air plug for switching and go out
Mouth air plug realizes that the signal between on-pole switch and pole-mounted switch case 20 connects, by the shelves for stirring 4 road change-over switches 11
Position is to realize that pole-mounted switch case 20 connects different on-pole switch by transfer box.
4 road change-over switches 11 are made of universal change-over switch, model LW5D-16,4 entrance air plugs, 13,4 entrances
Air plug 13 is arranged in 10 bottom surface of cabinet, and the model of 4 entrance air plugs 13 is JN2101, TP-G7, ZFTU2-2, AIC- respectively
2C, operation voltage are DC220V.4 road change-over switch 11 is also connected with 3 outlet air plugs that 10 bottom surface of cabinet is arranged in,
It is 4 stitch air plugs 14,6 stitch of stitch air plug 15 and 10 air plugs 16 respectively, wherein 6 stitch air plugs 15 are anti-open ended air plugs, uses
