In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of cable trace test
Instrument, including transmitter module and receiver module, the transmitter module includes transmitting casing, transmitting coupling clamps, it is direct-connected to launch
Folder and ground wire, the emitter housing, which is provided with, makes what the direct-connected folder of transmitting or transmitting coupling pincers were connected with transmitting casing interior element
Jack, described direct-connected folder one end of transmitting and one end of transmitting coupling pincers are equipped with interior chalybeate plug, and the jack center is set
There is electromagnetism post, the plug, which is stretched on the shell in jack, is additionally provided with cross section as polygon or the annular slot of arc, institute
State the mobile column for being provided with and being caught in by the attraction of electromagnetism post in annular slot in jack；
The main frame portion of the receiver module including rectangle and the acceptance division being arranged on below main frame portion, in the main frame portion
Provided with display screen, the top in the main frame portion is also provided with the handle slot of convenient gripping, and the handle is arranged in handle slot.
Preferably, the return magnet for inhaling dynamic mobile column is additionally provided with the jack, control return magnetic is provided with the jack
The touch switch of Tie Tong electricity；Mobile column can be sucked back initial position after a loss of power.
Preferably, the mobile column has two, and two mobile columns are symmetrical arranged on electromagnetism mast axis, the annular
The cross section of neck is rectangle；Two mobile columns form pincer attack, and plug is firmly fixed.
Preferably, the main frame portion is provided with compass indicator；Before and after showing, prevent from judging by accident.
Compared with prior art, it is an advantage of the invention that：Using chalybeate plug and electromagnet, enable plug firm
Adsorb, while mobile column is caught in the annular slot of plug using the suction of electromagnet, further strengthen plug connection
Stability, prevent plug from deviating from socket, while handle slot is opened up at the top of main frame portion so that handle will not protrude again,
It is hardly damaged in transportation.
Brief description of the drawings
Fig. 1 is the structural representation of emitter housing in a kind of cable line tester of the present invention；
Fig. 2 connects sectional view for plug and socket in a kind of cable line tester of the present invention；
Fig. 3 is the structural representation of receiver module in a kind of cable line tester of the present invention.
Embodiment
It is a kind of embodiment of cable line tester of the present invention refering to Fig. 1 to Fig. 3, a kind of cable line tester, wraps
Include transmitter module and receiver module, the transmitter module includes transmitting casing 1, transmitting coupling pincers, launch direct-connected folder and
Ground wire, the emitter housing, which is provided with, makes the direct-connected folder of transmitting or transmitting coupling pincers be inserted with what transmitting casing interior element was connected
Hole, described direct-connected folder one end of transmitting and one end of transmitting coupling pincers are equipped with interior chalybeate plug 3, and the center of jack 2 is set
There is electromagnetism post 4, the annular slot 5 that cross section is rectangle, the jack 2 are additionally provided with the shell that the plug 3 is stretched into jack 2
Interior to be provided with the mobile column 6 being caught in by the attraction of electromagnetism post 4 in annular slot 5, the mobile column 6 has two, two mobile columns 6
Set on the axisymmetrical of electromagnetism post 4；The return magnet 11 for inhaling dynamic mobile column 6 is additionally provided with the jack 2, in the jack 2
The touch switch 12 being powered provided with control return magnet 11.
The receiver module includes the main frame portion 7 of rectangle and is arranged on the acceptance division 8 of the lower section of main frame portion 7, the main frame
Portion 7 is provided with display screen 13, and the top in the main frame portion 7 is also provided with the handle slot 9 of convenient gripping, and the handle 10 is arranged on handle
In hand groove 9, the main frame portion 7 is provided with compass indicator 14.
Battery powered is carried in transmitter module, emitter there are two kinds of launching techniques, and a kind of is the transmitting of inoperative cable
Method, emitter is opened, receive satellite clock signal, the plug 3 for launching direct-connected folder is inserted into the transmitting corresponding jack 2 of casing 1
Interior, the electromagnetism post 4 in jack 2 is powered, and attracts mobile column 6 to be caught in annular slot 5, and so as to fix, the direct-connected folder of transmitting is firm to be connected
Connect, the armouring of cable near-end ground wire untied, the cable armouring of opposite end keeps ground connection, signal with being added in armouring and power network it
Between, cable core keeps hanging.Signal spontaneous emission machine flows through armouring, enters the earth in cable opposite end, flows back to near-end and returns to transmitting
Machine.Shielding is not present in this connection, thus caused signal is most strong on the ground, and characteristics of signals is also relatively clearer and more definite.Similarly, since
The presence of armouring-the earth distribution capacity, signal can be from proximad remote gradually decay.Another kind is clamp coupled method, detects cable side
Just, efficiently method, it is not necessary to which cable, which makees any change, to be tested, and operates away from high pressure, very safe, in cable copper
Skin screen layer, armouring ground connection suggest making in this way when normal, process require that cable copper sheet screen layer, both ends armouring connect
Ground is good, if ground connection disconnects, or cable sheath has the place of disconnection, then will not form test electric current.If copper sheet screen layer, armour
Attaching it is not sufficiently good, then signal reduces with the increase of grounding resistance, will launch the plug 3 of one end that couples pincers and inserts transmitting
In the corresponding jack 2 of casing 1, the electromagnetism post 4 in jack 2 is powered, and attracts mobile column 6 to be caught in annular slot 5, so as to fix hair
The firm connection of direct-connected folder is penetrated, transmitting coupling pincers are stuck in the optional position of cable, and transmitting coupling pincers should be closure state, send letter
Number.For receiver module, turn on the power, receive satellite clock signal, operating personnel are held in handle slot 9, by receiver
Vertically it is placed in target cable, it is consistent notices that receiver positive direction should move towards direction with target cable.Bigness scale：Observe receiver screen
Cable position in curtain, path detection is carried out according to prompting.Accurate measurement：For constructing or accurately searching cable position, receiver is kept
It is vertical with estimated cable direction, find the maximum point of response, should not mobile receiver, its original place is rotated, finds response most
Big angle, angle is kept, moves left and right receiver, found the maximum point of response, perform mark.It can repeat the above steps,
To improve positioning precision.After being all completed, plug 3 is extracted touch switch 12 drives timer since transmitting casing 1
Work and powered to return magnet 11, mobile column 6 is sucked back into initial position.Using chalybeate plug and electromagnet, make plug
It can firmly adsorb, while mobile column is caught in the annular slot of plug using the suction of electromagnet, further strengthen
The stability of plug connection, prevents plug from deviating from socket, while open up handle slot at the top of main frame portion so that handle will not be again
It is prominent, it is hardly damaged in transportation.
