The main frame portion that described receiver module comprises rectangle and the acceptance division be arranged on below main frame portion, described main frame portion is provided with display screen, and the top in described main frame portion also has the convenient handle slot gripped, and described handle is arranged in handle slot.
Preferably, in described jack, be also provided with the return magnet inhaling dynamic mobile post, in described jack, be provided with the touch switch controlling the energising of return magnet; Mobile post can be sucked back initial position after a loss of power.
Preferably, described mobile post has two, and two described mobile posts are symmetrical arranged about electromagnetism mast axis, and the xsect of described annular slot is rectangle; Two mobile posts form pincer attack, firmly fix plug.
Preferably, described main frame portion is provided with compass indicator; Before and after showing, prevent erroneous judgement.
Compared with prior art, the utility model has the advantages that: utilize chalybeate plug and electromagnet, plug can firmly be adsorbed, simultaneously utilizing the suction of electromagnet to make mobile post snap in the annular slot of plug, the stability that further reinforcement plug connects, makes plug not deviate from socket, offers handle slot at top, main frame portion simultaneously, handle can not be given prominence to again, not fragile in transportation.

Fig. 1 is the structural representation of transmitter housing in a kind of cable line tester of the utility model;
Fig. 2 is that in a kind of cable line tester of the utility model, plug and socket connects cut-open view;
Fig. 3 is the structural representation of receiver module in a kind of cable line tester of the utility model.
Embodiment
Consult the embodiment that Fig. 1 to Fig. 3 is a kind of cable line tester of the utility model, a kind of cable line tester, comprise transmitter module and receiver module, described transmitter module comprises launches casing 1, launch coupling pincers, launch direct-connected folder and ground wire, described transmitter housing is provided with and makes the direct-connected folder of transmitting or launch coupling pincers and launch the jack that in casing, element is connected, one end of described transmitting direct-connected folder one end and transmitting coupling pincers is equipped with interior chalybeate plug 3, described jack 2 center is provided with electromagnetism post 4, described plug 3 stretches on the shell in jack 2 and is also provided with the annular slot 5 that xsect is rectangle, be provided with in described jack 2 and attract by electromagnetism post 4 the mobile post 6 that snaps in annular slot 5, described mobile post 6 has two, two described mobile posts 6 are arranged about electromagnetism post 4 axisymmetrical, also be provided with the return magnet 11 inhaling dynamic mobile post 6 in described jack 2, in described jack 2, be provided with the touch switch 12 controlling return magnet 11 and be energized.
The main frame portion 7 that described receiver module comprises rectangle and the acceptance division 8 be arranged on below main frame portion 7, described main frame portion 7 is provided with display screen 13, the top in described main frame portion 7 also has the convenient handle slot 9 gripped, described handle 10 is arranged in handle slot 9, and described main frame portion 7 is provided with compass indicator 14.
With powered battery in transmitter module, transmitter has two kinds of launching techniques, a kind of is the launching technique of inoperative cable, transmitter is opened, receive satellite clock signal, being inserted by the plug 3 launching direct-connected folder launches in casing 1 corresponding jack 2, electromagnetism post 4 in jack 2 is energized, mobile post 6 is attracted to snap in annular slot 5, thus fix and launch direct-connected folder and firmly connect, untied by the armouring ground wire of cable near-end, the cable armouring of opposite end keeps ground connection, signal is added between armouring and electrical network ground, and cable core keeps unsettled.Signal self-emission machine flows through armouring, enters the earth, flow back to near-end and return transmitter in cable opposite end.There is not shielding in this connection, the signal thus produced on the ground is the strongest, and characteristics of signals is also clearer and more definite.Equally, due to the existence of armouring-the earth distributed capacitance, signal can from proximad far decaying gradually.Another kind is clamp coupled methods, exploration cable is method easily and efficiently, do not need cable to do any change can test, and operation is away from high pressure, very safe, when cable copper sheet screen layer, armouring ground connection are normal, suggestion makes in this way, this method requires that the ground connection of cable copper sheet screen layer, two ends armouring is good, if ground connection disconnects, or cable sheath has the place of disconnection, then can not form measuring current.If copper sheet screen layer, armouring ground connection are good not, then signal reduces with the increase of stake resistance, being inserted by the plug 3 of the one end of launching coupling pincers launches in casing 1 corresponding jack 2, electromagnetism post 4 in jack 2 is energized, attract mobile post 6 to snap in annular slot 5, thus fix and launch direct-connected folder and firmly connect, launch coupling pincers and be stuck in the optional position of cable, launch coupling pincers and should be closure state, send signal.For receiver module, opening power, receive satellite clock signal, operating personnel hold in handle slot 9, are vertically placed in target cable by receiver, notice that receiver positive dirction should to move towards direction consistent with target cable.Bigness scale: observe cable position in receiver screen, carry out path detection according to prompting.Accurate measurement: for constructing or accurately searching cable position, keeps receiver vertical with the cable direction of expectation, finds the point that response is maximum, not mobile receiver, its original place is rotated, finds the angle that response is maximum, keep angle, move left and right receiver, find the point that response is maximum, perform mark.Above-mentioned steps can be repeated, to improve positioning precision.After being all completed, plug 3 being extracted touch switch 12 from transmitting casing 1 and drives timer to start working to power to return magnet 11, mobile post 6 is sucked back into initial position.Utilize chalybeate plug and electromagnet, plug can firmly be adsorbed, simultaneously utilizing the suction of electromagnet to make mobile post snap in the annular slot of plug, the stability that further reinforcement plug connects, plug is made not deviate from socket, offer handle slot at top, main frame portion simultaneously, handle can not be given prominence to again, not fragile in transportation.
