The invention discloses a cable path tester. An insertion hole is formed in an emitter casing, an insertion head contains iron materials, an electromagnetic column is arranged in the center of the insertion hole, an annular clamping groove with a polygonal or arc cross section is further formed in a shell, extending into the insertion hole, of the insertion head, and movable columns attracted by the electromagnetic column to be clamped into the annular clamping groove are arranged in the insertion hole. A receiver assembly comprises a rectangular host portion and a receiving portion arranged at the lower portion of the host portion, a display screen is arranged on the host portion, a handle groove conveniently held is further formed in the top of the host portion, and a handle is arranged in the handle groove. The cable path tester has the advantages that the insertion head can be firmly attracted through the insertion head containing the iron materials and an electromagnet, the movable columns are clamped into the annular clamping groove of the insertion head through the attraction force of the electromagnet, and the connection stability of the insertion head is further reinforced, so that the insertion head cannot be disengaged from an insertion base. A handle groove is formed in the top of the host portion at the same time, and in this way, the handle cannot protrude out, and is unlikely to be damaged in the transportation process.
Description
technical field [0001] The invention relates to a cable path tester. Background technique [0002] At present, there are two methods for cable detection. The first one is to use the method of transmitting carrier wave or pulse current signal at the user end; the traditional pipeline instrument adopts the amplitude recognition technology, which is used in pipeline branch points and other special occasions (due to the position or direction of the pipeline) It may cause the amplitude intensity of the non-target pipeline to be higher than that of the target pipeline, thus causing misjudgment. The second method is to use a path meter to apply a frequency signal to the loop formed by the target cable and the earth, and use the receiver to find the position directly above the cable at the position where the signal of this frequency received on the ground is the strongest. When adopting the second method, the launch line or the launch coupling clamp are generally used, both of whic...
