Problems solved by technology

[0002] With the vigorous development of domestic rail transit construction in major cities, trams have gradually begun to be put into operation in major cities. During the operation process, vehicle maintenance is an important part of ensuring the safety of vehicles. At present, the earliest domestic trams put into operation are Trams have entered the maintenance stage one after another. The reliability of electrical connectors in electrical components determines the probability of electrical fires. However, there is no systematic and unified maintenance method for vehicle electrical connectors in this field, which has a great impact on the quality assurance of vehicles. difference
[0003] At present, the maintenance of electrical connectors in this field is mainly based on the overall replacement of electrical connectors, which increases the maintenance cost and is an extensive technical management method, which is extremely unfavorable compared with the low-income operation of trams. However, the operation and management units have different test methods for the contact resistance of electrical connectors, so improper methods will lead to inaccurate test results

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 A method for overhauling a tram electric connector is shown, the steps of the method are,

[0026] S1. Decompose the electrical connector. The electrical connector is fixed on the tram through fasteners. In the process of decomposing the electrical connector, the fasteners of different electrical connectors need to be stored separately to avoid mixed installation; The connector is composed of a shell, pins, jacks, insulating plates, seals and mechanical connection structures. During maintenance, not only the above structural parts must be overhauled, but also the insulation resistance and contact resistance at the pins and jacks. to test.

[0027] S2. Check the internal thread of the threaded hole of the fastener. Visual inspection, if there is a thread defect in the thread, the thread defect includes damage, corrosi...

Abstract

The invention relates to a maintenance method for an electrical connector of a tramcar, and the method comprises the steps: S1, decomposing the electrical connector; S2, checking internal threads of athreaded hole of the fastener; S3, checking a connector shell; S4, checking a connector jack and a contact pin; S5, checking the insulating plate; S6, checking a sealing piece; S7, detecting a mechanical component; S8, carrying out an insulation resistance test on the electrical connector; S9, performing a contact resistance test on the electrical connector; S10, assembling each part of the electrical connector, sleeving a cable sheath on each part, and leaving an overhaul record. The tramcar electrical connector maintenance method is systematized, and the tramcar electrical connector maintenance process is standardized; the maintenance quality problem of the tramcar electrical connector is solved, and potential safety hazards are reduced; a detailed and reliable contact resistance testing method is provided, and the reliability of the electrical connector is effectively judged; and the maintenance cost of the tramcar operation unit on the electrical connector is reduced.
