Description

Technical Field

[0001] This invention relates to the field of interface plug-in / plug-out testing technology, specifically to a quick positioning mechanism for plug-in / plug-out connectors. Background Technology

[0002] In the automatic insertion and removal aging test, the insertion and removal test connector needs to be positioned before subsequent insertion and removal tests can be carried out. In order to ensure the authenticity of the interface insertion and removal, the alignment needs to be constantly adjusted to find the most central insertion and removal position of the test interface in order to ensure the accuracy of the insertion and removal test. Currently, the positioning is done manually, which is cumbersome, complicated and time-consuming. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application provides a quick positioning mechanism for plug-in connectors, comprising:

[0004] Test connector, used to insert into the interface under test;

[0005] A connector fixing shaft is used to connect the test connector;

[0006] The quick positioning mechanism for the plug-in connector is characterized in that it further includes:

[0007] A floating suction cup is used to connect the connector fixing shaft;

[0008] An electromagnet is used to attract the fixing shaft of the connector onto the floating suction cup;

[0009] The connector fixing shaft is axially perpendicular to the end face of the floating suction cup, and the connector fixing shaft can move along a preset range on the floating suction cup.

[0010] Furthermore, the quick positioning mechanism for the plug-in connector also includes:

[0011] The limiting block is connected to the electromagnet;

[0012] The cam positioner is connected to the limiting block via a telescopic shaft;

[0013] One end of the telescopic shaft can move within the limiting block, while the other end extends out of the cam positioner.

[0014] Furthermore, a limiting hole is provided in the limiting block, and one end of the telescopic shaft moves within the limiting hole through a limiting member. The limiting block is used to limit the travel of the telescopic shaft.

[0015] Furthermore, the axial direction of the telescopic shaft is parallel to the axial direction of the joint fixing shaft.

[0016] Furthermore, the floating suction cup has a mounting groove and a limiting groove, the electromagnet is installed in the mounting groove, and the connector fixing shaft is movably disposed in the limiting groove.

[0017] Furthermore, a movable disk is provided in the limiting groove, and one end of the joint fixing shaft is connected to the movable disk. The movable disk can only move along the plane where its own end face is located.

[0018] Furthermore, a through hole is provided between the mounting groove and the limiting groove to facilitate the electromagnet's attraction of the moving disk.

[0019] Furthermore, the diameter of the movable disk is larger than the diameter of the through hole, thereby preventing the movable disk from falling into the through hole and thus making it impossible for the movable disk to move within the limiting groove.

[0020] Furthermore, the connector fixing shaft is connected to the test connector via a thread.

[0021] The quick positioning mechanism for plug-in connectors provided in this application has the following advantages:

[0022] (1) By setting a cam positioner, telescopic shaft and limit block, the stroke of the test connector is fixed, the positioning is more accurate, and the interface will not be damaged.

[0023] (2) The electromagnet adsorption fixation method allows for quick positioning by adjusting the approximate position, which greatly shortens the process and time of joint alignment;

[0024] (3) The entire mechanism adopts a modular design, which supports quick replacement and convenient maintenance;

[0025] (4) The connector fixing shaft and the test connector are connected by threads, which makes it easy to adapt to test connectors of different specifications and has high versatility. Attached Figure Description

[0040] See Figure 1-7 This embodiment provides a quick positioning mechanism for a plug-in connector, including a test connector 10, a connector fixing shaft 11, a floating suction cup 12, an electromagnet 13, a limiting block 15, and a cam positioner 14 arranged sequentially. One end of the connector fixing shaft 11 is connected to the test connector 10, and the other end is connected to the floating suction cup 12. The electromagnet 13 is connected to the floating suction cup to attract the connector fixing shaft 11 onto the floating suction cup. The cam positioner 14 is connected to the limiting block 15 via a telescopic shaft 16. The connector fixing shaft 11 can move along a preset range on the floating suction cup 12, and one end of the telescopic shaft 16 can move within the limiting block 15, while the other end extends out of the cam positioner 14.

[0041] Specifically, the floating suction cup 12 has a mounting groove 121 and a limiting groove 122, which are respectively opened at both ends of the floating suction cup. The electromagnet 13 is installed in the mounting groove 121, and the connector fixing shaft 11 is movably arranged in the limiting groove 122.

[0042] In order to allow the connector fixing shaft 11 to move within the range of the limiting groove, a movable disk 18 is provided in the limiting groove 122. One end of the connector fixing shaft is connected to the movable disk 18. A through hole 123 is opened between the mounting groove 121 and the limiting groove 122 to facilitate the electromagnet to attract the movable disk.

[0043] More specifically, the diameter of the movable disk 18 is larger than the diameter of the through hole 123. When the electromagnet 13 is not energized, in order to prevent the movable disk from falling, a cover plate 124 is provided on the limiting groove 122. The connector fixing shaft 11 is set through the cover plate 124. The cover plate is also provided with a movable hole 125 so that the connector fixing shaft 11 can move within the range of the limiting groove.

[0044] It should be noted that the two ends of the movable disk 18 are respectively attached to the bottom wall of the cover plate 124 and the limiting groove 122 to ensure that the positioning disk can only move along the plane where the bottom wall of the limiting groove 122 is located, and cannot move in the direction perpendicular to the bottom wall of the limiting groove. At the same time, in order to improve the alignment accuracy of the test joint and ensure the smooth movement of the movable disk, the inner wall of the limiting groove 122 and the movable disk 18 are both made by grinding.

[0045] To improve the versatility of the positioning mechanism and facilitate the adaptation to test connectors of different specifications, the connector fixing shaft 11 has a main body 111. The two ends of the main body 111 are a first connecting part 112 and a second connecting part 113, respectively. External threads (not shown in the figure) are provided on the first connecting part 112 and the second connecting part 113, respectively, forming threaded connections with the moving disk 18 and the test connector 10. For ease of assembly, the diameter of the main body 111 is larger than the diameter of the first connecting part 112 and the second connecting part 113.

[0046] Specifically, such as Figure 7 As shown, a limiting hole 151 is opened in the limiting block 15. The limiting hole 151 is a stepped hole opened inward along the end face of the limiting block. One end of the telescopic shaft 16 moves in the limiting hole through the limiting member 17. An end cover 152 is provided on the end face of the limiting hole. The end cover 152 also has a through hole corresponding to the position of the limiting hole 151. The diameter of the through hole is smaller than the diameter of the limiting hole, so that the limiting member 17 can only move within the axial range of the limiting hole. The extension of the telescopic shaft to the outside of the cam positioner 14 is used to connect with other equipment to realize the installation of the entire positioning mechanism.

[0047] Working principle: After the entire positioning mechanism is installed, the test connector 10 is first inserted into the test interface. This insertion process is manually controlled by the entire positioning mechanism. Since one end of the telescopic shaft is fixed on other equipment, the entire positioning mechanism can move along the axial direction of the telescopic shaft. At this time, the electromagnet is not energized, so the connector fixing shaft 11 can be moved to adjust the insertion position. The test connector can be inserted by manually adjusting the approximate position near the interface. After the test connector is inserted into the test interface, the cam positioner 14 is then turned to fix the insertion stroke of the test connector for subsequent insertion and removal tests. Finally, the electromagnet is energized to engage and position the connector, and then repeated insertion and removal tests can be performed.

[0048] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
