In the present embodiment, for installing the installing hole of input port and being arranged on different sidewalls for installing the installing hole of output port
On, it is possible to effectively prevent port misconnection or misconnection.Such as: as shown in Figures 2 and 3, the front side wall of casing 11 is provided with use
In the installing hole 12 of installation input port, the rear wall of casing 11 is provided with the installing hole 13 for installing output port.Separately
Outward, front side wall is additionally provided with installing hole 14, for installing alarm module (i.e. light emitting diode and the buzzing on warning branch road
Device).
When outside line is detected, for one of them detector unit, by the two ends of outside line and this detection list
The input port 4 of unit and the corresponding connection of output port 5, particularly as follows: the current output terminal of outside line connects input port 4, outward
The current input terminal of portion's circuit connects output port 5, if it addition, input port 4 and output port 5 are arranged respectively to inserted terminal
Son and probe, then can be quickly connected；When outside line line is normal, the current output terminal of outside line, input
The current input terminal of mouth 4, input detection line 2, power supply module 6, output detections line 3, output port 5 and outside line is formed
One current loop, now, due to unilateral conduction and the relation of current potential height, warning branch road does not has electric current to flow through, luminous
Diode 8 is the most luminous, buzzer 9 not sounding；When outside line line is abnormal, in such as outside line there is broken string in somewhere
Situation, the electric current in outside line cannot form current loop by input port 4 and output port 5, now power supply
Module 6 provides electric energy for warning branch road, and the light emitting diode 8 in warning branch road is luminous, and buzzer 9 is sounded a buzzer simultaneously, carries
Showing operator, outside line line to be measured is abnormal.
Further, in order to also be able to when outside line line is normal point out operation by certain cue
Person, on the connection line between input port 4 and output port 5, also string is provided with an indicating module, i.e. this indicating module and electricity
Source module is arranged in series, so, outside this indicating module is arranged on power module and between input port 4 and output port 5
Connection line on.This indicating module is an instruction branch road, so, as it is shown in figure 1, between power branch and output port 5
Output detections line 3 can as this instruction branch road, on this instruction branch road string be provided with display lamp 10, in the present embodiment, this refers to
The color showing the light that lamp 10 sends is green, and the color of the light that the light emitting diode 8 in warning branch road sends is redness, then,
When outside line line is normal, between input port 4 and output port 5, pass sequentially through input detection line 2, power supply module
6 and output detections line 3 form a current loop, display lamp 10 sends green glow, and prompting operator's outside line line is normal, this
Time, due to unilateral conduction and the relation of current potential height, warning branch road does not have electric current to flow through, light emitting diode 8 is the most luminous, honeybee
Ring device 9 not sounding；When outside line line is abnormal, in such as outside line there is the situation of broken string, outside line in somewhere
In electric current cannot form current loop by input port 4 and output port 5, display lamp 10 is the most luminous, now power supply
Module 6 provides electric energy for warning branch road, and light emitting diode 8 sends red light, simultaneously 9 buzzers of buzzer, points out operator,
Outside line line to be measured is abnormal.The line of visual representation outside line is carried out by exporting the light of different colours under different conditions
State.
In above-described embodiment, on power branch, string is provided with power supply module 6 and build-out resistor 7, as other enforcement
Example, if the circuit of this power branch own has certain resistance, this build-out resistor 7 be can omit no.

Other embodiment, the input detection line 2 between power branch and input port 4 can also be defined as indicating branch road, two kinds of feelings
Operation principle under condition is identical.
In above-described embodiment, instruction branch road is outside power branch, as other embodiment, all right on power branch
Display lamp 10 is set, as shown in Figure 4, like this, when outside line line is normal, between input port 4 and output port 5
Passing sequentially through input detection line 2, power supply module 6 and output detections line 3 and form a current loop, display lamp 10 is bright, this
Time, due to unilateral conduction and the relation of current potential height, warning branch road does not have electric current to flow through, light emitting diode 8 is the most luminous, honeybee
Ring device 9 not sounding；When outside line line is abnormal, in such as outside line there is the situation of broken string, outside line in somewhere
In electric current cannot form current loop by input port 4 and output port 5, now power supply module 6 is warning branch road
Thering is provided electric energy, display lamp 10 is still able to shinny, and light emitting diode 8 is luminous, 9 buzzers of buzzer simultaneously, points out operator,
Outside line line to be measured is abnormal.So, in this embodiment, no matter outside line line is the most normal, and display lamp 10 is all sent out
Bright.
It is presented above specific embodiment, but this utility model is not limited to described embodiment.This practicality
Novel basic ideas are above-mentioned basic scheme, for those of ordinary skill in the art, according to teaching of the present utility model,
Design the model of various deformation, formula, parameter are not required to spend creative work.Without departing from principle of the present utility model
With the change in the case of spirit, embodiment carried out, revise, replace and modification still falls within protection domain of the present utility model
In.
