[0002] With the development of the automotive industry, the demand for vehicle testing is increasing. The OBD connector is crucial for vehicle diagnostics and troubleshooting, offering functions such as data recording, fault code diagnosis, real-time monitoring, and software updates. During automotive research and development and production, data is frequently collected via the OBD connector, making its durability a key industry concern. Current methods for testing the durability of OBD connectors involve operators manually inserting and removing the connector from its socket on a test bench, recording the lifespan based on the number of insertions and removals and the degree of wear.

[0003] While the above methods can achieve the testing objective in practical applications, they consume a lot of manpower, reducing testing efficiency; they also prolong the entire insertion and removal test cycle and introduce more unstable factors, thus reducing the reliability of the test.

[0017] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0018] like Figure 1-2As shown, this utility model provides an OBD plug insertion / removal detection device for automating the insertion / removal detection of OBD plugs and compatible OBD ports. The OBD plug insertion / removal detection device includes a detection frame 1, a fixing component 2, a plug / removal device 3, and a clamp 4. The fixing component 2 is provided on the bottom surface of the detection frame 1. The plug / removal device 3 is vertically fixed on the detection frame 1, with its output end facing downwards and fixedly connected to a clamp 4 for holding and fixing the OBD plug. The plug / removal device 3 includes a cylinder 31, a magnetic switch 32, a solenoid valve 33, and a controller 34. Magnetic switches 32 for feedback of cylinder piston position information are provided on the outer sides of both ends of the cylinder 31. The air inlet of the solenoid valve 33 is connected to an air supply unit 35 via an air inlet pipe. The two air supply ends are connected to the DC valves 31a on both ends of the cylinder 31 via air supply pipes. The magnetic switch 32 and the solenoid valve 33 are electrically connected to the input and output ends of the controller 34, respectively. When the cylinder piston moves to both ends, the corresponding magnetic switch is triggered. The magnetic switch will feed back the piston position information to the controller in real time. The controller can then control the solenoid valve to supply air to the cylinder in reverse, thereby realizing the cyclic insertion and removal motion. The specific positions of the magnetic switches on both ends of the cylinder can be adjusted according to the test requirements to change the distance of the cylinder's reciprocating motion, thereby adjusting the insertion or removal distance of the OBD plug. The speed of the cylinder's reciprocating motion can also be changed by adjusting the DC valve on the cylinder, thereby adjusting the insertion or removal speed of the OBD plug.

[0019] The testing frame 1 is a rectangular hollow shape; this reduces the overall weight of the device and facilitates observation of the OBD plug during the test.

[0020] The fixing component 2 includes several magnetic bases 21 located on the bottom surface of the testing frame 1; the magnetism of the magnetic bases can be turned on or off by manually toggling a switch, so that they can be firmly attached to most of the flat and vertical surfaces of the metal workbench.

[0021] The solenoid valve 33 is powered by DC 24V. In this embodiment, the solenoid valve 33 is preferably a dual-electrically controlled two-position five-way solenoid valve, which has the advantages of precise control and fast response.

[0022] The air supply unit 35 is an air compressor; the air pressure can be adjusted according to the actual situation using a pressure reducing valve.

[0023] The clamp 4 includes, but is not limited to, small frog pliers, small flat-nose pliers, etc., with frog pliers being preferred in this embodiment; it is used to securely clamp the OBD plug.

[0024] The OBD plug insertion and removal testing device provided by this utility model can realize automated reciprocating insertion and removal testing of OBD plugs, is easy to standardize and widely used; it reduces the labor intensity of workers, improves testing efficiency, shortens the entire insertion and removal testing cycle, and ensures testing reliability.
