Description

Technical Field

[0001] This application relates to the technical field of oil pump motors, and in particular to a plug-in interface for an oil pump motor. Background Technology

[0002] An improved type of motor for driving an oil pump includes a motor body, a front cover, and an output drive shaft. A stepped hole is opened on the front cover, and the output drive shaft is retracted into the front cover and is a hollow shaft. The diameter of the shaft hole matches the outer diameter of the input drive shaft of the oil pump. There is a keyway at the end of the output drive shaft. Oil pumps are divided into high-pressure and low-pressure types. The high-pressure plunger oil pump is driven by a camshaft in the pump to drive the plunger to reciprocate up and down in the plunger sleeve, generating high-pressure oil to supply the injector.

[0003] A search revealed Chinese Patent Publication No. CN219268676U, which discloses a plug-in interface for an oil pump motor, an oil pump motor, an oil pump, and a gearbox. The plug-in interface is located on the manifold of the oil pump motor, which is used to fix the control board of the oil pump motor. The plug-in interface is a hollow, open-top square shell with a rounded rectangular cross-section. A boss protruding along the axial direction of the bottom center of the plug-in interface is provided, which is used to fix multiple pins of the oil pump motor. The surface of the boss has multiple openings for the ends of the pins to pass through. The edge of the boss is connected to the inner wall of the plug-in interface by multiple reinforcing ribs distributed around the perimeter of the boss. During operation, the plug-in interface is inserted into the client, allowing the multiple pins to form an electrical connection with the client. The plug-in interface proposed in this application, by setting a boss and reinforcing rib structure in the plug-in interface, can not only meet the injection molding requirements and prevent problems such as bubbles, collapse, and shrinkage, but also enhance the strength of the plug-in interface.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the above-mentioned solutions and prior art, a locking component is lacking between the plug and the connector interface. Vibrations and impacts occur during vehicle operation and oil pump motor operation, causing the plug to easily loosen or detach from the connector interface. To address this issue in the prior art, which is prone to loosening or detachment due to vibrations generated during vehicle operation and oil pump motor operation, this application incorporates components such as connectors, clips, and springs. The inclined surfaces of the connectors and clips allow the clips to compress the springs. When the plug is installed in place, the springs reset the clips, locking the connector and preventing the plug from loosening or detaching. This device effectively prevents the plug from loosening or detaching due to vibrations and impacts generated during vehicle operation or oil pump motor operation. Utility Model Content

[0005] In order to improve the connection strength between the plug and the connector interface and prevent the plug from loosening or falling off due to vibration and impact generated during vehicle driving or oil pump motor operation, this application provides a connector interface for an oil pump motor.

[0006] This application provides a plug-in interface for an oil pump motor, employing the following technical solution: It includes a plug, with two connectors fixedly connected to its left side. The left side of the plug is provided with two connecting plates and equidistantly arranged clips. Each connecting plate has two connecting rods fixedly connected to its inner wall. Each clip has a fixing block fixedly connected to its opposite side. The inner wall of each fixing block is fixedly connected to the end of the corresponding connecting rod closest to it. Each fixing block has two springs fixedly connected to its opposite side.

[0007] Optionally, each of the connecting plates has a limiting block on one side that is close to each other, and the other end of each spring is fixedly connected to the outer surface of the corresponding limiting block.

[0008] Optionally, the inner wall of each limiting block is slidably connected to the outer surface of the corresponding connecting rod, and a magnetic block is fixedly installed on the side of each limiting block that is far apart from each other.

[0009] Optionally, each of the magnetic blocks is provided with a magnetic block 2 on its outer surface, and the outer surface of each magnetic block 2 is fixedly connected to the side of the corresponding connecting plate that is close to each other.

[0010] Optionally, the plug has a plug interface body on its left side, a cable is fixedly installed on its right side, and an installation body is fixedly connected to its left side.

[0011] Optionally, the upper and lower surfaces of the plug-in interface body are fixedly connected to the sides of the corresponding limiting blocks that are close to each other, and the inner wall of the plug-in interface body is provided with pins arranged at equal intervals.

[0012] Optionally, guide plates are fixedly connected to the upper and lower surfaces of the plug-in interface body. Each guide plate has a cavity on its side that is close to each other. The inner wall of each cavity is in sliding contact with the outer surface of the corresponding connector and clip.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by incorporating components such as connectors, connecting rods, fixing blocks, clips, and springs, allows the connector to push open the corresponding clips via the inclined surface on the left side when connecting the plug to the plug-in interface. This causes the clips to move relative to each other, which in turn moves the fixing block and connecting rod, compressing the spring. Once the plug and plug-in interface are connected, the connector is in place. At this point, the spring causes the fixing block to reset, which in turn moves the clips and connecting rod. The corresponding clips on both sides lock the connector in place. This device, through the connection between the clips and the connector, prevents the plug from loosening or falling off, thus preventing the plug from loosening or falling off due to vibrations and impacts during vehicle operation or oil pump motor operation.

[0015] 2. This utility model incorporates components such as limiting blocks, magnetic block one, magnetic block two, and a guide plate. Limiting blocks are installed on the upper and lower surfaces of the plug-in interface body, connecting the connecting rod to the limiting blocks in a sliding connection configuration. This limits the movement of the connecting rod, ensuring stability during the movement of the card. Magnetic block one is connected to the limiting blocks, and magnetic block two is connected to the connecting plate. Magnetic blocks one and two are placed correspondingly; their mutual attraction enhances the locking effect of the card on the connecting member, ensuring reliable connection. The guide plate, with its cavity, limits the movement of both the connecting member and the card. Combined with the card and connecting member, this further improves the reliability of the connection between the plug and the plug-in interface body. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4This application will be described in further detail.

[0022] This application discloses a plug-in interface for an oil pump motor. For example... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device includes a plug 1. Two connectors 2 are fixedly connected to the left side of the plug 1. Two connecting plates 3 and equally spaced clips 6 are provided on the left side of the plug 1. Two connecting rods 4 are fixedly connected to the inner wall of each connecting plate 3. The connectors 2 are installed on the left side of the plug 1 and are set as fixed connections. The connectors 2 can move with the plug 1 as it moves. The connecting plates 3 and clips 6 are set on the left side of the plug 1, and the connecting rods 4 are installed on the inner wall of the corresponding connecting plates 3 and are set as fixed connections. The connecting rods 4 can move as the connecting plates 3 move.

[0023] Combination Figure 3 and Figure 4 The plug 1 has a plug interface body 11 on its left side and a cable 14 fixedly installed on its right side. The plug interface body 13 is fixedly connected to the left side of the plug interface body 11. The plug interface body 11 is located on the left side of the plug 1 and can be connected to the plug 1. The cable 14 is installed on the right side of the plug 1 and can supply power to the plug interface body 11 through the plug 1. The mounting body 13 is located on the left side of the plug interface body 11 and can be connected to the junction box on the surface of the oil pump motor.

[0024] In this embodiment, guide plates 15 are fixedly connected to the upper and lower surfaces of the plug-in interface body 11. Each guide plate 15 has a cavity 16 on its side that is close to each other. The inner wall of each cavity 16 is in sliding contact with the outer surface of the corresponding connector 2 and clip 6. The guide plates 15 are installed on the upper and lower surfaces of the plug-in interface body 11 to achieve the positioning and installation effect of the guide plates 15. The cavities 16 are opened on the side that is close to each other of the guide plates to achieve the positioning of the cavities 16. The inner wall of the cavity 16 is in contact with the surface of the corresponding connector 2 and clip 6, so that the plug 1 and the plug-in interface body 11 can be positioned and installed.

[0025] In this embodiment, each card 6 has a fixing block 5 fixedly connected to its opposite side. The inner wall of each fixing block 5 is fixedly connected to the opposite end of the corresponding connecting rod 4. Two springs 7 are fixedly connected to the opposite side of each fixing block 5. The fixing block 5 is connected to the corresponding card 6 and fixed on the opposite side of the card 6 to achieve the positioning and installation effect of the fixing block 5. The fixing block 5 is connected to the corresponding connecting rod 4 to form a fixed connection. By moving the connecting plate 3, the connecting rod 4 can drive the card 6 to move relative to each other through the fixing block 5. The springs 7 are installed on the opposite side of the corresponding fixing block 5 to form a fixed connection. The springs 7 can press the fixing block 5 tightly to facilitate the reset of the card 6.

[0026] In a preferred embodiment, each connecting plate 3 is provided with a limiting block 8 on one side that is close to each other, and the other end of each spring 7 is fixedly connected to the outer surface of the corresponding limiting block 8. By setting the limiting block 8 on one side that is close to each other and connecting the spring 7 with the corresponding limiting block 8, the other end of the spring 7 is limited, thereby enabling the fixing block 5 and the clip 6 to be quickly reset by the spring 7.

[0027] In a preferred embodiment, the upper and lower surfaces of the plug-in interface body 11 are fixedly connected to the corresponding limiting blocks 8 on their adjacent sides. The inner wall of the plug-in interface body 11 is provided with pins 12 arranged at equal intervals to connect the limiting blocks 8 to the plug-in interface body 11, thus achieving a fixed connection and realizing the positioning and installation effect of the limiting blocks 8. The pins 12 are a kind of metal material that completes the conductive transmission of electrical signals.

[0028] like Figure 4 As shown, the inner wall of each limiting block 8 is slidably connected to the outer surface of the corresponding connecting rod 4. A magnetic block 9 is fixedly installed on the side of each limiting block 8 that is far apart from each other. The connecting rod 4 is connected to the corresponding limiting block 8, and the connection between them is set as a sliding connection. The limiting block 8 is used to limit the connection rod 4 and ensure the stability of the connecting rod 4 when it moves. The magnetic block 9 is installed on the side of the limiting block 8 that is far apart from each other and is set as a fixed connection to achieve the positioning and installation effect of the magnetic block 9.

[0029] In this embodiment, each magnetic block 9 has a magnetic block 2 10 on its outer surface. The outer surface of each magnetic block 2 10 is fixedly connected to the side of the corresponding connecting plate 3 that is close to each other. The magnetic block 2 10 is placed on the side of the magnetic blocks 9 that is far away from each other, and the magnetic block 2 10 can be connected to the magnetic block 9. The magnetic block 2 10 is connected to the corresponding connecting plate 3 and is set as a fixed connection. Through the connection between the magnetic block 1 9 and the magnetic block 2 10, the connection strength between the card 6 and the connecting member 2 can be improved, and the spring 7 can be prevented from shaking.

[0030] The implementation principle of the plug-in interface of an oil pump motor in this application embodiment is as follows: When the plug 1 needs to be installed, the plug 1 is moved to drive the connector 2 to move, so that the connector 2 enters the cavity 16 and the corresponding clip 6 is pushed open by the inclined surface on the left side, so that the clip 6 moves relative to each other. The clip 6 causes the fixing block 5 and the connecting rod 4 to move, thereby compressing the spring 7. After the connection is completed, the connector 2 is installed in place. At this time, the fixing block 5 can be reset under the action of the spring 7, thereby causing the fixing block 5 to drive the clip 6 and the connecting rod 4 to move. The corresponding clips 6 on both sides can lock the connector 2. The connection strength is improved by magnetic block 1 9 and magnetic block 2 10 to prevent the spring 7 from shaking, thus preventing the plug 1 from loosening and preventing the vibration and impact generated by the oil pump motor during operation from inducing the plug 1 to loosen or fall off. When disassembly is required, the connecting plates 3 on both sides are moved to release the limiting of the clip 6 and the connector 2, so that the plug 1 can be pulled out.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
