Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted devices, and in particular to a quick connection device. Background Art

[0002] OBD (On Board Diagnostics) is an on-vehicle automatic diagnostic system used to monitor the working conditions of the electronic control system of an automobile engine and other functional modules of the vehicle. Currently, an external OBD diagnostic device is electrically connected to the OBD circuit board inside the vehicle through a plug and a wire. When the plug is electrically inserted into the OBD diagnostic interface, the vehicle condition information can be obtained and transmitted to the diagnostic device, so that the vehicle condition can be effectively diagnosed.

[0003] When manufacturing an OBD diagnostic device, it is usually necessary to use a test device that simulates an automotive ECU to test the performance of the OBD diagnostic device. Through the test device, production quality inspection of the OBD diagnostic device can be completed. It is more rapid and convenient to test the OBD diagnostic device compared to using an actual vehicle for quality inspection. During the test, first insert the connector into the test device, and then insert the plug of the OBD diagnostic device into the connector to achieve communication connection and obtain diagnostic data.

[0004] Regarding the above related technology, an interface is provided on the connector, and probes are provided in the interface. When the plug is inserted into the interface, electrical connection is achieved through the probes to obtain vehicle condition data. During multiple tests of the OBD diagnostic device, the plug is continuously inserted and removed from the connector interface, resulting in certain wear and deformation of the probes, which may cause poor electrical contact and affect the normal progress of the OBD diagnostic device test. Summary of the Invention

[0005] In order to solve the problem that the probes will be worn to a certain extent after multiple repeated uses, resulting in poor electrical contact and affecting the normal progress of the OBD diagnostic device test, the present application provides a quick connection device.

[0006] A quick connection device provided by the present application adopts the following technical solutions:

[0007] A quick connection device includes:

[0008] A socket, provided with multiple groups of mounting holes;

[0009] A PCB board, one side of the PCB board is in contact and fixed with one side of the socket, and the other side is used for electrical connection with the test device;

[0010] Multiple probe assemblies, corresponding one-to-one to the number of the mounting holes, each probe assembly including a base and a probe detachably connected, the base being electrically connected to the PCB board and located on the side of the PCB board close to the socket, and the base and the probe being inserted through the mounting hole;

[0011] The probe includes two probe clips, both of the two probe clips being electrically connected to the base, the two probe clips having elastic potential energy of approaching each other, and the two probe clips being used for electrically connecting with an external plug.

[0012] By adopting the above technical solutions, first, when the OBD diagnostic device is subjected to factory testing, when the plug is inserted into the socket, the two probe clips can effectively abut against the pins of the plug, and the stability of the electrical connection can be ensured by increasing the contact area and the abutting force. Second, the probe clip is detachably connected to the base. After being used multiple times, if the probe clip is severely worn, it can be replaced in time. Third, by modularly connecting and fixing the socket and the PCB board to the testing device, the service life of the device can be greatly extended, the cost can be effectively reduced, and the mismeasurement phenomenon caused by unstable connection during the OBD diagnostic device testing is basically eliminated. The device of the present application can ensure the convenience and the stability of the electrical connection during the OBD diagnostic device testing, and greatly improve the efficiency of the OBD diagnostic device factory testing.

[0013] Optionally, it further includes a plurality of moving components corresponding one-to-one to the number of the mounting holes, the moving components being used for driving the two probe clips to approach or separate from each other; when the external plug is inserted into the socket, the two probe clips approach each other, and when the external plug is away from the socket, the two probe clips separate from each other.

[0014] By adopting the above technical solutions, when the probe clip is electrically plugged with the external plug, there is a certain friction between the probe clip and the external plug. After being used multiple times, the probe clip is easily subject to a certain frictional loss. When the external plug is inserted into the socket, the two probe clips approach each other, and when the external plug is away from the socket, the two probe clips separate from each other. Therefore, the friction between the probe clip and the external plug can be effectively reduced, thereby ensuring the durability of the device in use and improving the efficiency of the OBD diagnostic device testing.

[0015] Optionally, the moving component includes:

[0016] A driving member, slidably connected to the side wall of the mounting hole, and used for sliding along the extending direction of the mounting hole under the action of the external plug;

[0017] Two connecting rods, each connecting rod being fixedly connected to a probe clip, and the driving member driving the two connecting rods to approach or separate from each other;

[0018] and a reset member, located on the inner wall of the mounting hole and on one side of the driving member, for resetting the driving member.

[0019] By adopting the above technical solution, the driving member can effectively drive the two connecting rods to approach each other, thereby driving the two probe clips to approach each other. When the external plug is away from the socket, at this time, the reset member can drive the driving member to reset, so that the two connecting rods move away from each other, and further the two probe clips move away from each other. Therefore, the frictional loss between the probe clip and the external plug can be effectively reduced, and the service life of the device can be further improved.

[0020] Optionally, the driving member includes a driving plate, the driving plate is slidably connected to the hole wall of the mounting hole, two oblong holes are formed on the driving plate, and the openings formed by the two oblong holes face the direction of the driving plate close to the PCB board. Each connecting rod passes through one of the oblong holes, and a contact rod is further arranged in the inner wall of the mounting hole, and the contact rod is used to limit the movement of the connecting rod along the direction perpendicular to the extension direction of the mounting hole.

[0021] By adopting the above technical solution, the two oblong holes formed on the driving plate can drive the connecting rod to move along the hole wall of the oblong hole, and the contact rod can further limit the moving direction of the connecting rod, so that the connecting rod can only move perpendicular to the extension direction of the mounting hole, so that the connecting rod can effectively drive the probe clips to approach or move away from each other. Since the connecting rod does not move in other directions, the electrical connection between the probe clip and the base can be effectively guaranteed, so as to ensure the effectiveness and stability of the electrical connection during the test of the OBD diagnostic device.

[0022] Optionally, the driving member further includes a driving rod, the driving rod is fixedly connected to the driving plate, the driving rod is located between the two probe clips, and the thickness of the driving rod is less than the thickness of the pin of the external plug.

[0023] By adopting the above technical solution, since the contact area between the plug-in piece on the plug and the space in the mounting hole may be limited, the driving rod can effectively abut against the plug, so that the plug pushes the driving rod to move, and then pushes the driving plate to move. Among them, the thickness of the driving rod does not affect the abutment between the plug-in piece on the plug and the probe clip. The driving rod can ensure that the plug effectively drives the driving plate to move, so as to ensure the electrical connection, reduce the situation that the test result may be incorrect due to no electrical connection, and ensure the accuracy of the OBD diagnostic device test.

[0024] Optionally, the reset member is arranged as an elastic cord, one end of the elastic cord is fixedly connected to the hole wall of the mounting hole away from the PCB board, and one end is fixedly connected to the driving plate.

[0025] By adopting the above technical solution, when an external plug is inserted into the socket, the elastic cord is stretched at this time, and the frictional force between the plug and the socket can prevent the plug from resetting under the action of the elastic cord. When the external plug is pulled out of the socket, at this time, the elastic cord drives the driving plate away from the PCB board, so that the driving plate resets, and then drives the two probe clips to move away from each other, facilitating the next test. There is no relative sliding between the plug and the probe clips all the time, so the frictional loss can be effectively reduced.

[0026] Optionally, a first limiting member and a second limiting member are provided on the side wall of the mounting hole. The first limiting member and the second limiting member are located on two opposite sides of the driving plate. The first limiting member is used to limit the driving plate from moving towards the PCB board, and the second limiting member is used to limit the driving plate from moving away from the PCB board.

[0027] By adopting the above technical solution, the first limiting member can limit the driving block from approaching the PCB board. When the external plug is inserted into the socket, the second limiting member can offset a part of the elastic force of the elastic cord, reducing the magnitude of the force that the external plug receives and moves away from the socket. The first limiting member and the second limiting member can improve the convenience of the device for testing the OBD diagnostic device.

[0028] Optionally, the first limiting member includes an elastic body. The elastic body is provided with an abutting groove. The cross-sectional shape of the abutting groove is set to be wavy. A plug block corresponding to the position of the elastic body and matching the shape of the abutting groove is provided on the side of the driving plate away from the PCB board. The plug block approaches or moves away from the elastic body; the second limiting member is arranged in a mirror image of the first limiting member.

[0029] By adopting the above technical solution, after the plug block is inserted into the abutting groove, due to their wavy shapes, they have a certain clamping effect. The plug block will be abutted by the wall of the abutting groove, so it can have a certain limiting effect.

[0030] Optionally, a bent portion is formed on the side of the probe clip close to the base. A limiting groove is correspondingly formed at the corresponding position on the base. The bent portion approaches or moves away from the limiting groove, and the bent portion is electrically connected to the base at the limiting groove.

[0031] By adopting the above technical solution, the bent portion increases the contact area between the probe clip and the base, so the electrical connection effect between the probe clip and the base can be correspondingly ensured, thus ensuring the stability of the electrical connection for testing the OBD diagnostic device.

[0032] Optionally, an opening is formed by bending the sides of the two probe clips away from the base, and the opening faces the direction in which the probe clips are away from the base.

[0033] By adopting the above technical solution, the opening formed by bending the two probe clips can initiate a certain guiding effect, thus ensuring the convenience of inserting the external plug into the socket.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. The device of the present application can ensure the convenience and electrical connection stability during the test of the OBD diagnostic device, greatly improving the efficiency of the factory test of the OBD diagnostic device;

[0036] 2. The moving component can effectively reduce the friction between the probe clip and the external plug, thereby ensuring the durability of the device; the driving rod can ensure that the plug effectively drives the driving plate to move, thus ensuring electrical connection;

[0037] 3. The first limiting member and the second limiting member can improve the convenience of the device for testing the OBD diagnostic device, and further reduce the friction loss between the probe clip and the external plug. Description of the Drawings

[0048] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 8 , to further elaborate on the present application.

[0049] It should be noted that in the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0050] The embodiment of the present application discloses a quick connection device.

[0051] Referring to Figure 1 , when the OBD diagnostic device 9 is tested before leaving the factory, the OBD diagnostic device 9 needs to be electrically connected to the testing device 8 through wires and plugs, so as to effectively detect the diagnostic effect of the OBD diagnostic device 9, ensure that the OBD diagnostic device 9 can effectively obtain the vehicle condition data of the vehicle when it is subsequently used for vehicle testing, and thus complete the troubleshooting and repair of the vehicle.

[0052] Embodiment 1

[0053] Referring to Figure 2 and Figure 3 , a quick connection device includes a socket 1, a PCB board 2 and multiple groups of probe assemblies 3.

[0054] Referring to Figure 2 and Figure 3 , the socket 1 is provided with multiple groups of mounting holes 11. In this embodiment, the socket 1 is made by 3D printing. One side of the PCB board 2 is in contact and fixed with one side of the socket 1, and the other side is used for electrical connection with the testing device 8, specifically, it can be connected to the testing device 8 through a female header and a flexible cable.

[0055] Referring to Figure 3 and Figure 4, The number of multiple probe assemblies 3 corresponds one-to-one to the number of mounting holes 11. The probe assembly 3 includes a base 31 and a probe 32 that are detachably connected, specifically, they can be detachably connected by welding or threaded connection, etc. The base 31 is electrically connected to the PCB board 2. The base 31 is made of wire, so it can achieve electrical connection with the PCB board 2 and the probe 32. The base 31 is located on the side of the PCB board 2 close to the socket 1, and both the base 31 and the probe 32 are inserted through the mounting hole 11.

[0056] Refer to Figure 2 and Figure 3 , After the socket 1, the PCB board 2, and multiple probe assemblies 3 are installed, they form a unified module. When performing the factory test on the OBD diagnostic device 9, the OBD diagnostic device 9 is electrically connected to the test device 8 through a plug and a wire, so it can effectively test the OBD diagnostic device 9. The modular design can improve the convenience of testing and plugging of the OBD diagnostic device 9, and improve the stability of electrical connection, reducing the occurrence of mismeasurement.

[0057] After multiple tests, the probe 32 may be worn or deformed, which may cause poor electrical contact. The device of the present application can replace the probe 32 in time. Since it is not necessary to replace the entire connection device, the test cost can be effectively reduced.

[0058] Refer to Figure 4 , The probe 32 includes two probe clips 321. Both of the two probe clips 321 are electrically connected to the base 31. The two probe clips 321 have elastic potential energy to approach each other, and the two probe clips 321 are used to be electrically connected to an external plug.

[0059] When the external plug is inserted into the mounting hole 11, the pins of the external plug can effectively abut against the two probe clips 321, thus ensuring the stability of electrical connection. Since the probe clips 321 have a certain elastic abutting force, the stability of electrical connection during the test of the OBD diagnostic device 9 can be effectively guaranteed, reducing the occurrence of mismeasurement, and thus improving the test effect on the OBD diagnostic device 9.

[0060] Among them, refer to Figure 4 , One side of the two probe clips 321 away from the base 31 is bent to form an opening, and the opening faces the direction away from the base 31 of the probe clips 321. Bending to form an opening has a certain guiding effect, so as to effectively ensure that the external plug is inserted between the two probe clips 321 to ensure electrical connection.

[0061] The implementation principle of Embodiment 1 is as follows: When testing the OBD diagnostic device 9, the OBD diagnostic device 9 is electrically connected to the test device 8 through a plug and wires, thereby completing the test of the OBD diagnostic device 9. Among them, when the plug is inserted into the socket 1, the pins of the plug can effectively push and abut against the contact pieces of the two probes 32, thereby ensuring the stability of the electrical connection.

[0062] Embodiment 2

[0063] Referring to Figure 5 and Figure 6 This embodiment is different from Embodiment 1 in that: In this embodiment, a quick connection device further includes a moving component 4. In this embodiment, the moving component 4 corresponds to the number of mounting holes 11 one by one, and the moving component 4 is used to drive the two probe clips 321 to approach or move away from each other; when the external plug is inserted into the socket 1, the two probe clips 321 approach each other, and when the external plug is away from the socket 1, the two probe clips 321 move away from each other.

[0064] Specifically, referring to Figure 5 and Figure 6 the moving component 4 includes a driving member 41, two connecting rods 42 and a reset member 43 (as shown in Figure 8 ).

[0065] Referring to Figure 7 and Figure 8 the driving member 41 is slidably connected to the side wall of the mounting hole 11, and the driving member 41 is used to slide along the extending direction of the mounting hole 11 under the action of the external plug. The driving member 41 includes a driving plate 411 and a driving rod 412. In this embodiment, the driving plate 411 is mounted on the side wall of the mounting hole 11, and there are two driving plates 411, and the two driving plates 411 are located on opposite sides ( Figure 6 the left and right opposite sides from a certain perspective), and the two ends of the driving rod 412 are respectively fixedly connected to the driving plate 411. Each connecting rod 42 is fixedly connected to a probe clip 321, and the driving member 41 drives the two connecting rods 42 to approach or move away from each other (as shown in Figure 6 ).

[0066] The driving plate 411 is slidably connected to the hole wall of the mounting hole 11, specifically, it can be slidably connected through a chute. Two oblong holes are formed on the driving plate 411, and the openings formed by the two oblong holes face the direction of the driving plate 411 close to the PCB board 2. Each connecting rod 42 passes through one oblong hole. The driving rod 412 is fixedly connected to the driving plate 411, and the driving rod 412 is located between the two probe clips 321 (as shown in Figure 6 ), and the thickness of the driving rod 412 is less than the thickness of the pin of the external plug.

[0067] When an external plug is inserted into socket 1, the external plug pushes the driving rod 412 to move, thereby driving the driving plate 411 to move along the extension direction of the sliding groove, that is, along the extension direction of the mounting hole 11, so that the driving plate 411 drives the two connecting rods 42 to approach each other through the two oblong holes, thereby driving the two probe clip pieces 321 to approach each other and abut against the pins of the external plug, thus ensuring the stability of the electrical connection.

[0068] Since when the external plug is inserted into socket 1, the pins of the external plug do not need to push open the probe clip pieces 321, and only abut against both sides of the probe clip pieces 321 after being fully inserted into socket 1. There is no relative sliding between the two, so the frictional loss between the two can be reduced, further improving the durability of the device and the efficiency of testing the OBD diagnostic device 9.

[0069] The driving rod 412 located between the two probe clip pieces 321 can reduce the situation where the pins of the external plug cannot effectively drive the driving plate 411 to move, improve the stability and accuracy of the device during testing, and reduce the occurrence of missed plugging. At the same time, the thickness setting of the driving rod 412 will not affect the effective abutment between the pins of the external plug and the probe clip pieces 321, and can further improve the testing efficiency of the device.

[0070] Refer to Figure 7 and Figure 8 As shown in FIGS. Figure 8 and Figure 8 , a contact rod 5 is further provided in the inner wall of the mounting hole 11. The contact rod 5 is used to limit the movement of the connecting rod 42 in the extension direction of the mounting hole 11. Specifically, there are two contact rods 5. The axial direction of the contact rod 5 is perpendicular to the extension direction of the mounting hole 11, and the contact rod 5 is located on both sides of the connecting rod 42, and the contact rod 5 abuts against the connecting rod 42. That is, the contact rod 5 is arranged in the left-right direction in the perspective view of

[0071] Refer to Figure 7 and Figure 8 , the reset member 43 is located on the inner wall of the mounting hole 11 and on one side of the driving member 41, and is used to reset the driving member 41. When the external plug is pulled out, the reset member 43 can effectively drive the driving member 41 to reset, that is, the driving member 41 can move away from the PCB board 2, and the driving member 41 drives the two probe clip pieces 321 to move away from each other, thus facilitating the next test.

[0072] In this embodiment, the reset member 43 includes an elastic cord 431. One end of the elastic cord 431 is fixedly connected to the hole wall of the mounting hole 11 away from the end of the PCB board 2, and the other end is fixedly connected to the driving plate 411. When the external plug is pulled out, the elastic cord 431 can make full use of its elastic potential energy to drive the driving plate 411 away from the PCB board 2.

[0073] It can be understood that in other embodiments, the reset member 43 can also be made of other elastic materials, or other common reset methods can be used to drive the driving plate 411 to reset in time.

[0074] Refer to Figure 7 and Figure 8 , a bending portion is formed on one side of the probe clip 321 close to the base 31 to form an abutting portion 322. A limiting groove 311 is formed at a corresponding position on the base 31. The abutting portion 322 approaches or moves away from the limiting groove 311, and the abutting portion 322 is electrically connected to the base 31 at the limiting groove 311. Inserting the abutting portion 322 of the probe clip 321 into the limiting groove 311 can effectively increase the contact area between the probe clip 321 and the base 31, thereby effectively ensuring the stability of the electrical connection between the probe clip 321 and the base 31, and further ensuring the stability of the subsequent test of the OBD diagnostic device 9, and further improving the test efficiency.

[0075] Refer to Figure 7 and Figure 8 , a first limiting member 6 and a second limiting member 7 are provided on the side wall of the mounting hole 11. The first limiting member 6 and the second limiting member 7 are located on two opposite sides of the driving plate 411. The first limiting member 6 is used to limit the driving plate 411 from moving towards the PCB board 2, and the second limiting member 7 is used to limit the driving plate 411 from moving away from the PCB board 2. That is, according to Figure 8 in the perspective direction, the first limiting member 6 limits the PCB board 2 from moving to the left, and the second limiting member 7 limits the PCB board 2 from moving to the right.

[0076] Specifically, the first limiting member 6 includes an elastic body 61. The elastic body 61 is provided with an abutting groove, and the cross-sectional shape of the abutting groove is set to be wavy. A plug-in block 62 corresponding to the position of the elastic body 61 and matching the shape of the abutting groove is provided on the side of the driving plate 411 away from the PCB board 2. The plug-in block 62 approaches or moves away from the elastic body 61; the second limiting member 7 is arranged in a mirror image of the first limiting member 6. The first limiting member 6 and the second limiting member 7 are located at both ends of the moving direction of the driving plate 411, that is, Figure 8 the left and right ends in the perspective of

[0077] When the external plug is inserted into socket 1, the external plug drives the driving rod 412 to move at this time, thereby driving the driving plate 411 to move. At this time, the plug-in block 62 on the driving plate 411 close to the second limiting member 7 is inserted into the abutting groove of the elastic body 61 of the second limiting member 7. Since the limiting block abuts against the elastic body 61, under the elastic pressure of the elastic body 61, it can resist a part of the pulling force of the elastic cord 431 received by the driving plate 411. At the same time, by means of the frictional force between the external plug and the outer wall of socket 1, the electrical connection between the external plug and socket 1 can be effectively ensured.

[0078] When the external plug is pulled out of socket 1, there is no such frictional force at this time. Under the pulling force of the elastic cord 431, the driving plate 411 moves, so that the plug-in block 62 on the left moves away from the elastic body 61. The driving plate 411 moves in a direction away from the PCB board 2, so that the plug-in block 62 close to the first limiting member 6 is inserted into the elastic body 61 on the right, ensuring that the driving plate 411 will not continue to slide due to gravity.

[0079] Among them, after the plug-in block 62 is inserted into the abutting groove, since both of them are wavy, they have a certain clamping effect. The plug-in block 62 will be abutted by the groove wall of the abutting groove, so it can have a certain limiting effect.

[0080] The implementation principle of Embodiment 2 is as follows:

[0081] When testing the OBD diagnostic device 9, the OBD diagnostic device 9 is electrically connected to the test device 8 through the external plug and the wire. During the process of inserting the external plug into socket 1, the external plug drives the driving rod 412 to move, thereby driving the driving plate 411 to slide, so that the two connecting rods 42 drive the two probe clips 321 to approach each other and abut against the pins of the external plug to achieve electrical connection. After the external plug moves away from socket 1, the reset member 43 drives the driving plate 411 to slide in the reverse direction, so that the two connecting rods 42 drive the two probe clips 321 to move away from each other, thus facilitating the next plug-in test. The above method can effectively reduce the wear and deformation between the external plug and the probe clip 321, thereby effectively improving the durability of the OBD device test and the stability of the electrical connection, and thus effectively improving the test efficiency of the OBD diagnostic device 9.

[0082] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
