Description

Technical Field

[0001] The utility model relates to the technical field of testing tooling, in particular to an electric car coupler testing docking device. Background Art

[0002] The split-and-join test is an important part of the advanced repair and debugging test of the Sifang platform EMU. It is necessary to check the electrical signals and logical relationships sent by the EMU electrical coupler one by one. At present, the EMU split-and-join test debugging is completed manually. During the test, two operators are required to use a multimeter to pressurize each probe, and three assistants are required to assist in other operations in the car. There are many electrical coupler probes and they are densely distributed. The split-and-join test test items include 18 grounding tests, 2 short-circuit tests, 126 power confirmation tests, 20 110V pressure tests, and 8 broadcast tests, totaling 174 items (there will be some differences in different models). The split-and-join test operation time is as long as 3 hours. During the entire test process, all 96 probes are exposed to the outside with electricity. There is a risk of slipping needles when measuring with a multimeter, and in severe cases, the circuit board may even be burned. The operator needs to concentrate highly. With the continuous improvement of delivery and quality requirements, it is necessary to improve the traditional test mode to improve operation efficiency and reduce operation risks.

[0003] Chinese patent CN105974227B discloses a tester for detecting electrical signals of train coupler electrical connectors. The tester provided by the invention includes a test module, a housing, and an operating panel connected to the front end face of the housing. The test module is arranged on the rear end face of the housing; the operating panel is provided with a display module connected to an integrated circuit board arranged in the housing; the test module includes a test needle holder and a test needle assembly arranged on the test needle holder; the test needle assembly is connected to the integrated circuit board. During operation, it is only necessary to align the test needle assembly with the electrical connector of the coupler and insert it, thereby avoiding burning of the electrical equipment in the vehicle due to the connection error of the operator. The tester in the present application adopts a modular design, which is simple to operate, easy to disassemble and assemble, and has strong practicality. It is conducive to standardized production and promotion, and solves the problems of many operators and long time consumption in the original test process; the test needle assembly will not be exposed to the outside, which improves the safety of the operator.

It has great improvements in docking with electric couplers and testing. Therefore, when the electric couplers are tested separately, the docking fit becomes particularly important, because it is urgent to develop a new docking device to improve the docking fit.
