Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of OBD diagnostic connectors, in particular to an automotive OBD diagnostic connector. Background Art
[0002] The OBD diagnostic connector refers to the OBD diagnostic interface on an automobile, which is used to connect diagnostic tools or devices for vehicle fault diagnosis and data reading. When using the OBD diagnostic connector, inserting the OBD diagnostic connector into the corresponding interface on the automobile can read the data of the automobile.
[0003] The above-mentioned and existing technologies have the following defects: When using the OBD diagnostic connector, the card frame on the OBD diagnostic connector is used to clamp in the interface of the automobile. Therefore, the card frame is often worn during use. After a period of time, it is easy for the card frame of the OBD diagnostic connector to be difficult to be in close contact with the interface of the automobile, resulting in poor contact between the OBD diagnostic connector and the interface of the automobile during use and slipping out, affecting the normal use of the OBD diagnostic connector.
[0004] Therefore, an automotive OBD diagnostic connector is proposed. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the defect that the worn OBD diagnostic connector is prone to poor contact with the interface of the automobile and slip out during use, and to propose an automotive OBD diagnostic connector.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An automotive OBD diagnostic connector includes a housing. A card frame is fixedly connected to the surface of the housing. Connection terminals are fixedly connected to the surface of the housing. A limiting frame is rotatably connected to the inner wall of the housing. A connecting belt is fixedly connected to the surface of the limiting frame. The connecting belt penetrates the housing. A bolt is rotatably connected to the surface of the housing. A transmission plate is threadedly connected to the arc surface of the bolt. The transmission plate is fixedly connected to the connecting belt. A cylindrical block is rotatably connected to the inner wall of the housing. The cylindrical block is slidably connected to the connecting belt.
[0007] The effects achieved by the above components are as follows: The bolt will drive the transmission plate to move away from the housing by means of the thread. When the transmission plate moves, it will pull the connecting belt. When the connecting belt moves along the surface of the cylindrical block, it will pull the limiting frame. The limiting frame will rotate and abut against the interface of the automobile. The limiting frame can increase the friction between the card frame and the interface of the automobile.
[0008] Preferably, a plurality of rubber blocks are fixedly connected to the surface of the limiting frame.
[0009] The effects achieved by the above components are as follows: The rubber blocks can increase the friction between the limiting frame and the interface of the automobile.
[0010] Preferably, a torsion spring is fixedly connected to the inner wall of the limit frame, and one end of the torsion spring is fixedly connected to the housing.
[0011] The effect achieved by the above components is that the torsion spring drives the limit frame to rotate by virtue of its own torsion, so that the limit frame can automatically reset.
[0012] Preferably, a groove is formed on the surface of the limit frame, a convex block is fixedly connected to the inner wall of the housing, and the groove is slidably connected to the convex block.
[0013] The effect achieved by the above components is that when the limit frame rotates due to the torsion of the torsion spring, the bottom inner wall of the groove on the limit frame contacts the convex block, and the convex block can limit the position of the limit frame, so that the limit frame is aligned with the clamping frame.
[0014] Preferably, a rotating block is fixedly connected to one end of the bolt, and a plurality of anti-slip grooves are formed on the arc surface of the rotating block.
[0015] The effect achieved by the above components is that when the rotating block is rotated, the anti-slip grooves can increase the friction force on the arc surface of the rotating block, and the rotation of the rotating block will drive the bolt to rotate.
[0016] Preferably, a fixing plate is fixedly connected to the surface of the housing, and the fixing plate is slidably connected to the transmission plate.
[0017] The effect achieved by the above components is that when the transmission plate slides along the surface of the fixing plate, the fixing plate restricts the moving path of the transmission plate and prevents the transmission plate from rotating along with the bolt.
[0018] Compared with the prior art, the advantages and positive effects of the present utility model are as follows
[0019] In the present utility model, when using an OBD diagnostic connector to read the data of an automobile, the rotating limit frame can be used to abut against the inner wall of the automobile interface, preventing the OBD diagnostic connector from slipping out of the automobile interface during use and ensuring the normal operation of the OBD diagnostic connector.

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0028] As Figures 1-5 shown, the present utility model provides an automotive OBD diagnostic connector, including an outer shell 1, a clamping frame 2 fixedly connected to the surface of the outer shell 1, a connection terminal 3 fixedly connected to the surface of the outer shell 1, a limit frame 4 rotatably connected to the inner wall of the outer shell 1, a connection belt 5 fixedly connected to the surface of the limit frame 4, the connection belt 5 passing through the outer shell 1, a bolt 6 rotatably connected to the surface of the outer shell 1, a transmission plate 7 threadedly connected to the arc surface of the bolt 6, the transmission plate 7 being fixedly connected to the connection belt 5, a cylindrical block 8 rotatably connected to the inner wall of the outer shell 1, the cylindrical block 8 being slidably connected to the connection belt 5, the bolt 6 driving the transmission plate 7 to move away from the outer shell 1 by means of the thread, the movement of the transmission plate 7 pulling the connection belt 5, the connection belt 5 pulling the limit frame 4 when moving along the surface of the cylindrical block 8, and the limit frame 4 rotating and abutting against the interface of the vehicle, and the limit frame 4 can increase the friction between the clamping frame 2 and the interface of the vehicle.
[0029] As Figures 1-5 shown, a plurality of rubber blocks 9 are fixedly connected to the surface of the limit frame 4, and the rubber blocks 9 can increase the friction between the limit frame 4 and the interface of the vehicle. A torsion spring 10 is fixedly connected to the inner wall of the limit frame 4, one end of the torsion spring 10 being fixedly connected to the outer shell 1, and the torsion spring 10 driving the limit frame 4 to rotate by means of its own torsion, so that the limit frame 4 can automatically reset. A groove 14 is provided on the surface of the limit frame 4, and a protrusion 15 is fixedly connected to the inner wall of the outer shell 1, and the groove 14 is slidably connected to the protrusion 15. When the limit frame 4 rotates due to the torsion of the torsion spring 10, the bottom inner wall of the groove 14 on the limit frame 4 contacts the protrusion 15, and the protrusion 15 can limit the position of the limit frame 4, so that the limit frame 4 is aligned with the clamping frame 2.
[0030] As Figures 1-5 shown, one end of the bolt 6 is fixedly connected with a rotating block 12. A plurality of anti-slip grooves 13 are formed on the arc surface of the rotating block 12. By rotating the rotating block 12, the anti-slip grooves 13 can increase the friction force of the arc surface of the rotating block 12. When the rotating block 12 rotates, it will drive the bolt 6 to rotate. A fixing plate 11 is fixedly connected to the surface of the housing 1. The fixing plate 11 is slidably connected with the transmission plate 7. When the transmission plate 7 slides along the surface of the fixing plate 11, the fixing plate 11 can limit the moving path of the transmission plate 7 and prevent the transmission plate 7 from rotating following the bolt 6.
[0031] The overall working principle is as follows: When it is necessary to use the OBD diagnostic connector to read the data of the vehicle, the torsion spring 10 will drive the limit frame 4 to rotate by means of its own torsion until the bottom inner wall of the groove 14 on the limit frame 4 contacts the convex block 15. The convex block 15 can limit the position of the limit frame 4, so that the limit frame 4 is aligned with the card frame 2. Then, move the housing 1 to insert the card frame 2 into the interface of the vehicle. The connection terminal 3 will be docked with the interface of the vehicle. Then, rotate the rotating block 12. The anti-slip grooves 13 can increase the friction force of the arc surface of the rotating block 12. When the rotating block 12 rotates, it will drive the bolt 6 to rotate. The bolt 6 will drive the transmission plate 7 to move away from the housing 1 by means of the thread. When the transmission plate 7 slides along the surface of the fixing plate 11, the fixing plate 11 can limit the moving path of the transmission plate 7 and prevent the transmission plate 7 from rotating following the bolt 6. When the transmission plate 7 moves, it will pull the connecting belt 5. When the connecting belt 5 moves along the surface of the cylindrical block 8, it will pull the limit frame 4. The limit frame 4 will rotate and abut against the interface of the vehicle. The limit frame 4 can increase the friction force between the card frame 2 and the interface of the vehicle. Even if the card frame 2 is worn, by changing the rotation angle of the limit frame 4, the situation that the card frame 2 slides out of the interface of the vehicle can be prevented. The rubber block 9 can increase the friction force between the limit frame 4 and the interface of the vehicle.
[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
