Description

Technical Field

[0001] This utility model relates to the field of electronic oil pump technology, and in particular to an electronic oil pump cylinder connector. Background Technology

[0002] The electronic oil pump mainly provides power to the vehicle's cooling system. Typically, the electronic oil pump includes an electronic control board. Because the operating environment of the electronic oil pump is relatively harsh, oil, water, high temperature, high humidity, etc. can all have a serious impact on the electronic control board.

[0003] Currently, the connectors of existing electronic oil pumps have poor sealing during use, allowing moisture or water to penetrate into the electronic control board, thus affecting its performance. Therefore, in order to improve the service life of electronic oil pumps and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the structure and application of the through-cylinder connector for electronic oil pumps in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing connectors have poor sealing performance, allowing moisture or water to penetrate into the electronic control board through the connector, thereby affecting the performance of the electronic control board. Therefore, this invention proposes an electronic oil pump cylinder-penetrating connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electronic oil pump cylinder connector includes a pump body. A connector head is fixedly connected to one side of the pump body. A first sealing ring is sleeved on the outer wall of the connector head. A convex ring is fixedly connected to one end of the connector head. A second sealing ring is snapped onto one end of the convex ring. A connector is sleeved on one end of the connector head. The second sealing ring contacts the inner wall of the connector. Multiple mounting plates are fixedly connected between the top and bottom inner walls of the connector head. A threaded hole is provided on one side of the mounting plate. A fastening screw is threaded into the threaded hole. One end of the fastening screw passes through one side of the connector. Multiple pins are fixedly connected to one side of the connector.

[0007] Furthermore, a plurality of sealing gaskets are snapped into one side of the inner wall of the connector, and the sealing gaskets are located at one end of the fastening screw.

[0008] Furthermore, the pump body is equipped with an electronic control board, and one end of the pin is electrically connected to the electronic control board.

[0009] Furthermore, the pump body has multiple connecting ears fixedly connected to its inner circumference, and the connecting ears are fixed to the electrical control board with screws.

[0010] Furthermore, a partition cover is fixedly connected to the top of the pump body, and the partition cover is connected to the motor.

[0011] Furthermore, a third sealing ring is snapped onto the top of the pump body, and the third sealing ring contacts the partition cover.

[0012] Furthermore, an end cap is fixedly connected to the bottom of the pump body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The first sealing ring and the L-shaped second sealing ring can effectively seal the connection head and connector, thereby improving the sealing performance between the connector and the connection head and preventing moisture or water from entering the pump body, so as not to affect the use of the electronic control board.

[0015] 2. By attaching a sealing gasket to one end of the fastening screw, one end of the fastening screw is sealed, thereby preventing moisture from seeping in from the connection between the fastening screw and the connector, thus improving waterproof performance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5An electronic oil pump cylinder connector includes a pump body 1. A connector head 2 is integrally formed on one side of the pump body 1. A connector 10 is sleeved on one end of the connector head 2. A first sealing ring 3 is sleeved on the outer wall of the connector head 2. A convex ring 4 is integrally formed on one end of the connector head 2. A second sealing ring 5 is snapped onto one end of the convex ring 4. The second sealing ring 5 contacts the inner wall of the connector 10. The first sealing ring 3 and the second sealing ring 5 are made of oil-resistant and heat-resistant materials, such as fluororubber FKM, with a compression ratio between 15% and 30% to avoid extrusion deformation. The first sealing ring 3 and the second sealing ring 5 are used to seal between the connector 10 and the connector head 2, thereby improving the sealing performance between the connector 10 and the connector head 2 and preventing moisture or water from entering the pump body 1.

[0024] Multiple mounting plates 6 are integrally formed between the top inner wall and the bottom inner wall of the connector 2. A threaded hole 7 is provided on one side of the mounting plate 6. A fastening screw 8 is threaded into the threaded hole 7. One end of the fastening screw 8 passes through one side of the connector 10. The fastening screw 8 is screwed into the threaded hole 7 through the connector 10, thereby fixing the connector 10 to one end of the connector 2.

[0025] Multiple sealing gaskets 9 are snapped into one side of the inner wall of the connector 10. The sealing gaskets 9 are located at one end of the fastening screw 8. The sealing gaskets 9 are snapped into one end of the fastening screw 8, thereby sealing one end of the fastening screw 8 and preventing moisture from seeping in from the connection between the fastening screw 8 and the connector 10.

[0026] The inner circumference of the pump body 1 is integrally formed with multiple connecting ears 13. The control board 12 is fixed by the connecting ears 13 and screws, which facilitates the installation of the control board 12. Multiple pins 11 are welded on one side of the connector 10. One end of the pin 11 is electrically engaged with the metal contact point on the control board 12, thus sealing the control board 12 with the inner wall of the pump body 1.

[0027] A partition cover 14 is fixed to the top of the pump body 1 by bolts. The partition cover 14 is connected to the motor. A third sealing ring 15 is snapped onto the top of the pump body 1. The third sealing ring 15 is made of the same material as the first sealing ring 3. The third sealing ring 15 contacts the partition cover 14, thereby sealing the partition cover 14 and the pump body 1. An end cover 16 is fixed to the bottom of the pump body 1 by bolts.

[0028] The working principle of this embodiment is as follows: In use, firstly, the connector 10 is put on one end of the connector head 2, then the fastening screw 8 is passed through the connector 10 and screwed into the threaded hole 7, thereby fixing the connector 10 on one end of the connector head 2, and electrically connecting the pin 11 to the control board 12. Next, the sealing gasket 9 is clamped on one end of the fastening screw 8, thereby sealing one end of the fastening screw 8 and preventing moisture from seeping in from the connection between the fastening screw 8 and the connector 10.

[0029] Then, the first sealing ring 3 and the second sealing ring 5 are used to seal the connector 10 and the connector 2, thereby improving the sealing performance between the connector 10 and the connector 2, and preventing moisture or water from entering the pump body 1 so as not to affect the use of the control board 12.
