Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a leak-proof power harness for an automotive brake electronic oil pump. Background Technology

[0002] During the braking process of a car, the electronic oil pump generates a braking effect. The power harness of the electronic oil pump is an essential component. According to the search, Chinese patent publication number CN212810794U discloses a leak-proof power harness for an electronic oil pump for car brakes. It includes a power cord, a first plug-in terminal and a second plug-in terminal. The first plug-in terminal has a connector inside that connects to the power cord. The other end of the connector is connected to a connecting conduit, and the other end of the connecting conduit is connected to a plug. The first plug-in terminal has a plug-in part, and the outer end of the plug-in part has a plug-in inner cavity. An elastic retaining strip is fixedly installed on the outer side of the first plug-in terminal.

[0003] The above-mentioned technical solution, by incorporating annular grooves, O-rings, waterproof rings, and threaded tubes, can improve the sealing of the connection between the power cord and the first and second plug terminals, effectively protect the power cord, and extend its service life. However, during use, the power cords at both ends are fixedly installed in the plug terminals via connectors. Therefore, in the event of damage, the entire power cord harness needs to be replaced, increasing maintenance costs. Furthermore, the threaded tubes used to protect the power cords cannot provide comprehensive protection for both ends of the power cord. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leak-proof power harness for automotive electronic brake pumps, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a power harness for preventing oil leakage of an electronic brake pump, comprising two symmetrically arranged ends, a power conductor being fixedly connected through the two ends, a connector being provided on one side of each end, a terminal being embedded and fixedly connected inside the connector, an elastic conductive post being provided between one end of the power conductor and one end of the terminal, a connection mechanism being provided between the end and the connector, and a protective mechanism being provided outside the power conductor;

[0006] The connection mechanism includes multiple screws, and the end and the terminal are fixedly connected by the screws. A first sealing ring is provided between the end and the terminal.

[0007] Preferably, one end of the connector is fixedly connected to a guide tube that mates with the interior of the connector, and a second sealing ring is provided between the end of the guide tube and the interior of the connector to increase the sealing between the connector and the connector.

[0008] Preferably, the elastic conductive post includes a conductive sleeve fixedly connected to one end of the power supply wire, a conductive rod that abuts against the terminal block is slidably connected inside the conductive sleeve, and a spring is provided inside the conductive sleeve to facilitate stable connection between the power supply wire and the terminal block.

[0009] Preferably, the outer surface of the connector has a groove, and a third sealing ring is embedded in the groove to increase the sealing between the connector and the outside.

[0010] Preferably, two elastic clips are symmetrically fixedly connected to both sides of the outer surface of the connector to facilitate the connection and disconnection of the connector.

[0011] Preferably, the protective mechanism includes a corrugated flexible tube sleeved over the power cord, with connecting sleeves fixedly connected to both ends of the corrugated flexible tube, and a rubber sleeve fixedly connected to one end of the tube to engage with the connecting sleeve, which can fully protect the power cord.

[0012] This utility model provides a leak-proof power harness for an automotive electronic brake fluid pump. It has the following advantages:

[0013] This automotive brake electronic oil pump anti-leakage power harness, through the setting of a connection mechanism and elastic conductive post, allows the originally integrated plug-in terminal to be changed to a split type. Therefore, it can be replaced according to any damaged location without replacing the whole unit, which can reduce maintenance costs. The setting of a protective mechanism can fully protect the power wire, making the two ends of the power wire less prone to damage and preventing impurities from coming into contact with the power wire, thereby improving the service life of the power wire.
