[0002] High-speed connectors are important components for signal transmission within or between electronic devices. They are specifically designed to transmit high-frequency signals and are widely used in servers, communication equipment, computers, automotive electronics, aerospace, and many other fields. Generally, high-speed connectors are tested after being installed on a workpiece. For example, a high-speed connector test fixture mentioned in authorization announcement number CN222212835U includes a fixed base, a first electric push rod installed on the inner wall of the fixed base, and a placement frame fixedly connected to one end of the first electric push rod. A clamping component is provided on the outer wall of the placement frame, and a moving component is provided on the top of the fixed base.

[0003] In this device, the workpiece is clamped and limited by rotating the screw. However, in actual application, the screw needs to be rotated multiple times when clamping and limiting the same workpiece. This is time-consuming, labor-intensive, and not user-friendly. Furthermore, it is difficult to clean the connection between the workpiece and the test piece by blowing air, which is not conducive to its widespread use. Utility Model Content

A test piece 9 is provided above the guide rail box 8. The test piece 9 is a known device for testing high-speed connectors. It is a common device and will not be described in detail here.

[0024] In use, first place the base box 1 in a suitable position, then place the workpiece with the high-speed connector on the placement rack 3, and limit the position of the workpiece by the clamp 12. Then control the extension and retraction of the upper and lower electric push rods 2 to drive the workpiece to adjust up and down. At the same time, control the servo motor 14 to drive the rotation of the lead screw 13 to adjust the position of the test piece 9, so that after the left and right electric push rods 15 are extended, the test piece 9 is just inserted into the high-speed connector of the workpiece, and the high-speed connector is tested.

[0029] Example 2

[0030] Please see Figure 2 The difference between this embodiment and Embodiment 1 is that:

[0031] A vent pipe 113 is fixedly connected to one side of the pressure tank 111. A solenoid valve is provided on the outer surface of the vent pipe 113. The vent end of the vent pipe 113 is fixedly connected to the jet pipe 10 via a hose. The bottom surface of the air pump 112 is fixedly connected to the pressure tank 111. The vent end of the air pump 112 is fixedly connected to the pressure tank 111 via a pipe. A pressure sensor is fixedly connected to one side of the pressure tank 111. The pressure sensor senses the air pressure inside the pressure tank 111. When the pressure is low, the air pump 112 will pressurize the pressure tank 111 to ensure that the internal pressure of the pressure tank 111 tends to be balanced. After the solenoid valve is opened, the gas inside the pressure tank 111 enters the jet pipe 10 through the vent pipe 113 to clean the connection between the workpiece and the test piece 9. The pressure sensor and the solenoid valve are known prior art. Those skilled in the art can install and use the pressure sensor and the solenoid valve according to the prior art. They will not be described in detail here.

[0032] It should be noted that, with the assistance of those skilled in the art, all electrical components in this case, such as the up and down electric push rods 2, the air pump 112, the servo motor 14, the left and right electric push rods 15, the air pressure detection sensor, and the solenoid valve, and their compatible power supplies, should be connected via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected based on the actual situation to meet the control requirements. When the air pressure detection sensor senses that the air pressure inside the pressure tank 111 is too low, it transmits the information to the controller via wires. The controller then starts and stops the air pump 112 based on the pressure information to ensure pressure balance inside the pressure tank 111. The specific connections and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not further explain the electrical control.

[0033] The working principle and usage process of this utility model are as follows: When limiting the position of a workpiece, the workpiece is placed in the inner cavity of the placement rack 3. Rotating the screw 7 causes the clamping plate 12 to move, clamping and limiting the workpiece. Furthermore, if the same type of workpiece is being positioned, pulling the protruding limiting post 53 above the limiting box 51 moves the assembly of the moving plate 52 and the limiting post 53, compressing the limiting spring 54 and causing it to deform. At this point, the limiting post 53 moves away from the limiting hole on the surface of the telescopic square tube 6. The telescopic square tube 6 can then be pulled, causing the clamping plate 12 to move away from the tested workpiece. Then, a new workpiece is placed in the placement rack 3. Push the telescopic square tube 6 to directly slide the clamping plate 12 against the newly placed workpiece. Then, release the limiting post 53. Under the action of the limiting spring 54, the limiting post 53 is reinserted into the corresponding limiting hole to limit the position of the telescopic square tube 6 assembly. This eliminates the need to repeatedly rotate the screw 7, reducing the workload of the operator. Furthermore, when it is necessary to perform insertion testing on the workpiece, the extension of the left and right electric push rods 15 drives the test piece 9 closer to the high-speed connector position of the workpiece. At this time, the solenoid valve is opened, and the high-pressure gas inside the pressure tank 111 enters the jet pipe 10 through the exhaust pipe 113 for jet cleaning, preventing dust and debris from affecting the test results.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
