Description

Technical Field

[0001] The utility model relates to the technical field of vehicle oil supply control systems, in particular to an automobile oil pump controller. Background Art

[0002] The fuel pump is one of the basic components of the fuel injection system of an electronic fuel injection vehicle. It is located inside the vehicle's fuel tank and its function is to suck the fuel from the fuel tank, pressurize it, and deliver it to the fuel supply pipe. It works with the fuel pressure regulator to establish a certain fuel pressure. The controller communicates with the engine and other related control units to control the load of the fuel pump according to the engine's needs. The fuel pump controller for automobiles currently on the market is directly composed of a transmission terminal and a housing. After injection molding, there is a gap between the transmission terminal and the housing, so the waterproof effect is poor, which makes the product's stability poor. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide an automobile oil pump controller with reasonable design, good waterproof effect and high stability in use.

[0004] The utility model adopts a technical solution to solve its technical problem. It is a fuel pump controller for automobile, comprising a controller housing and a plurality of transmission terminals. The front of the controller housing is provided with a mounting cavity, and a connector is integrally formed on the front side wall of the controller housing. One end of the transmission terminal is inserted into the mounting cavity, and the other end of the transmission terminal is inserted into the connector. The controller also includes a mounting block, and the other end of the transmission terminal is tightly inserted into the mounting block. The mounting block is pre-placed in a molding mold when the controller housing is integrally formed, and is wrapped in the connector after the controller housing is injection molded. A ring wall is also provided on the front side wall of the controller housing on the outside of the connector, and a ring cavity surrounding the outer wall of the connector is formed between the ring wall and the connector. A waterproof pad can be embedded in the bottom of the ring cavity, and a guide connection structure is also provided on the ring wall.

[0005] The advantages of adopting the above technical solution are as follows: by integrally forming the connector on the controller housing, the overall structure will be more stable compared to the method of combining components. By first inserting the transmission terminal into the other end of the connector and tightly inserting it into the mounting block, and then pre-placing the assembled component in the molding mold, the purpose of more tightly injection molding with the controller housing can be achieved.
