Embodiment 1

[0013] A wire joint detection device of the present invention includes a non-closed circuit connected in series by a resistance meter 6, a data acquisition and processor 6, and a power supply 7, and a test probe 1 4 and a test probe 2 5 are respectively arranged at both ends of the circuit.

[0014] When the circuit is overhauled, the circuit is disconnected, and then the diameter of the test wire A1 is tested by the test probe 1, the diameter of the test wire B2 by the test probe 2 5, and the distance between the test probe 1 4 and the test probe 2 5 is read at the same time. The diameter of B2 and the distance between test probe one 4 and test probe two 5, the test circuit can calculate the theoretical resistance value, compare the theoretical resistance value with the actual test value of resistance meter 6, if the theoretical value is much lower than the actual test value, it means This connector has excessive resistance and requires repair.

Description

technical field [0001] The invention relates to a circuit detection method, in particular to a wire joint detection device. Background technique [0002] The joints where the wires are connected to each other are inevitable in the circuit, and the joints are most likely to cause excessive resistance due to oxidation and other reasons, which will cause heat to burn the circuit. Therefore, when the circuit is overhauled, it is necessary to detect the joints of the electric wires. Contents of the invention [0003] The object of the present invention is to provide a wire joint detection device for the above problems. The device of the invention is simple in structure and easy to use, can accurately detect the connection status of the electric wire joint, judge circuit faults in time, and avoid danger caused by problems such as joint aging. [0004] The technical proposal of a wire joint detection device of the present invention includes a non-closed circuit connected in ser...
