Description

Technical Field

[0001] The utility model relates to the technical field of plug-in protection, in particular to an electrical plug-in protection component. Background Art

[0002] With the rapid development of new energy vehicles in recent years, the electrical safety issues of new energy vehicles have also received widespread attention. As the interface for the entire battery pack to provide power and charging to the entire vehicle, the safety protection of the electrical plug-in is particularly important. The creepage distance and electrical clearance between electrical parts are important indicators to measure whether electrical products are safe. If the creepage distance is too small, short circuits are likely to occur between the two poles of the power supply, and between the live parts and the shell of the electrical product, causing the power supply to short-circuit and the shell to be charged, which will greatly endanger personal safety; if the power supply is short-circuited, the electrical clearance between the live parts is too small, which is likely to cause inter-pole short circuits and leakage, thereby reducing the safety of the product.

[0003] At present, the distance between the fixing holes of most electrical plug-ins can meet the minimum creepage distance and electrical clearance. However, due to the limitation of the battery pack space, the fixing holes of some electrical plug-ins are too close and the plastic spacer between the two fixing holes is too short. When the overcurrent copper busbar is fixed by bolts, the height of the bolt head will exceed the height of the plastic spacer of the electrical plug-in itself, which makes the electrical clearance too small and endangers personnel safety. It also solves the hidden danger of workers accidentally touching the live bolt heads during inspection after assembly. Utility Model Content

[0004] In order to solve the above technical problems, the utility model uses an upper cover card plate to isolate the fastening bolts at both ends. The card slot structure of the upper cover card plate cooperates with the plastic spacer of the electrical plug-in to isolate the exposed bolt heads. The specific technical solution is as follows:

[0005] An electrical plug-in protective member comprises a protective member base, a hollow side of which is installed on the wiring side of the electrical plug-in; and a protective member upper cover, which is installed on the side of the protective member base away from the electrical plug-in, the wiring side of the electrical plug-in is provided with fastening bolts located at both ends of the protective member upper cover, and the middle part of the protective member upper cover is also provided with an upper cover card plate separating the fastening bolts.
