Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a cylinder-connecting device for an electronic oil pump in a new energy vehicle. Background Technology

[0002] A cylinder-penetrating connector is installed through the cylinder body, with one end located inside the cylinder body and the other end extending outside the cylinder body. This allows the electrical components inside the cylinder body to connect with the electrical components of the external control unit through the terminals of the cylinder-penetrating connector, thereby achieving mating between the cylinder-penetrating connector and the metal contacts inside the cylinder body, and serving to transmit current and signals. A search revealed that Chinese Patent Publication No. CN222673542U discloses a cylinder-penetrating connector, with one end passing through a mounting hole and connecting to a first female end, and the other end being sealed and connected to a second female end. The connector body includes a fixing part, a first insertion part, and a second insertion part; the first insertion part and the second insertion part are respectively located at both ends of the fixing part, with the first insertion part inserted into the first female end and the second insertion part inserted into the second female end.

[0003] The above technical solution uses a spring-loaded latch, which can smoothly pass through the mounting hole when elastically squeezed, and can be firmly engaged with the female end. It is also easy to disassemble and increases the stability of the connector. However, in use, since the terminals are integrated, they are prone to misalignment and squeezing during insertion and removal, resulting in gaps between the terminals and the main body. This necessitates the replacement of the entire connector, increasing costs. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a cylinder-penetrating connection device for an electronic oil pump in a new energy vehicle includes a column 1 for penetrating the oil pump cylinder. The two ends of the column 1 are respectively fixedly connected to a first connecting end 2 located inside the oil pump cylinder and a second connecting end 3 located outside the oil pump cylinder. A sealing mechanism is provided on the outer surface of the column 1. A plurality of first terminals 4 are fixedly connected through the first connecting end 2 and the column 1. A sliding plate 5 is slidably connected inside the second connecting end 3. A plurality of second terminals 6 are fixedly connected through the inside of the sliding plate 5. A connecting mechanism is provided between the first terminals 4 and the second terminals 6. A positioning mechanism that cooperates with the sliding plate 5 is provided on the outer surface of the second connecting end 3.

[0021] By mounting the second terminal 6 on the slide plate 5 and connecting it to the second terminal 6 via a connecting mechanism, the second terminal 6 can be replaced without affecting the sealing between the first terminal 4 and the inside of the column 1, thereby saving costs and increasing service life. The sealing mechanism can increase the sealing between the device and the column 1.

[0022] like Figure 1 and Figure 2 As shown, the sealing mechanism includes a positioning plate 8 fixedly connected to the outer surface of the column 1, a pressure plate 9 threadedly connected to the top of the column 1, and a first sealing gasket 10 and a second sealing gasket 11 respectively provided on one side of the positioning plate 8 and the pressure plate 9. Two sealing rings 7 are fitted onto the outer surface of the column 1.

[0023] By rotating the clamping plate 9, the sealing performance between the column 1 and the oil pump cylinder can be increased with the cooperation of the sealing ring 7, the first sealing gasket 10 and the second sealing gasket 11.

[0024] like Figures 2 to 4As shown, the connection mechanism includes a conductive sleeve 12 welded to one end of the first terminal 4. A conductive post 13 is slidably connected inside the conductive sleeve 12, and the top end of the conductive post 13 contacts the bottom end of the second terminal 6. A spring 14 is provided inside the conductive sleeve 12 to cooperate with the conductive post 13.

[0025] This allows for a stable connection between the first terminal 4 and the second terminal 6.

[0026] like Figures 1 to 3 As shown, the positioning mechanism includes symmetrical openings on both sides of the outer surface of the second connecting end 3. An elastic plate 15 is fixedly connected inside the opening. A locking block 16 is fixedly connected to the bottom end of the elastic plate 15. The outer surface of the slide plate 5 is provided with a locking groove that cooperates with the locking block 16 on both sides. A sealing plate 17 is fixedly connected to one side of the locking block 16.

[0027] The elastic plate 15 will cause the locking block 16 to reset, which facilitates the limiting of the sliding plate 5 and also facilitates the disassembly of the sliding plate 5 and the second terminal 6.

[0028] Both the outer surfaces of the first terminal 4 and the second terminal 6 are provided with slots to facilitate connection with external plugs.

[0029] Working principle: By installing the second terminal 6 on the slide plate 5 and connecting it to the second terminal 6 through the connecting mechanism, the second terminal 6 can be replaced without affecting the sealing between the first terminal 4 and the inside of the column 1, thereby saving costs and increasing service life. The sealing mechanism can increase the sealing between the device and the column 1.

[0030] By rotating the clamping plate 9, the sealing between the column 1 and the oil pump cylinder can be increased with the cooperation of the sealing ring 7, the first sealing gasket 10 and the second sealing gasket 11. The elastic plate 15 will drive the locking block 16 to reset, which facilitates the limiting of the sliding plate 5 and also facilitates the disassembly of the sliding plate 5 and the second terminal 6.
