DETAILED DESCRIPTION

[0020] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0021] Reference Figure 1-Figure 3 , shows a top and bottom press-fit plugging device of the present invention, which is used to plug multiple first signal terminals 11 of a test fixture box body 10 with multiple external second signal terminals 40, including a fixed frame 20, which is arranged on one side of the test fixture box body 10 and is correspondingly located directly above the first signal terminals 11, and the fixed frame 20 is provided with a telescopic driving member 21, and the telescopic end of the telescopic driving member 21 is downward and toward the first signal terminal 11; multiple second signal terminals 40 are embedded in a movable frame 30, and the movable frame 30 is connected to the telescopic end of the telescopic driving member 21, wherein the multiple second signal terminals 40 correspond one by one to the multiple first signal terminals 11.

[0022] In an embodiment of the present application, a fixed frame 20 is provided on one side of the test fixture box body 10 and is located directly above the first signal terminal 11. The fixed frame 20 is provided with a telescopic drive member 21, and the telescopic end of the telescopic drive member 21 is downward and toward the first signal terminal 11. A plurality of second signal terminals 40 are embedded in a movable frame 30, and the movable frame 30 is connected to the telescopic end of the telescopic drive member 21, wherein the plurality of second signal terminals 40 correspond one by one to the plurality of first signal terminals 11. By setting the first signal terminal 11 and the second signal terminal 40 to correspond one by one, and driving the movable frame 30 downward by the telescopic drive member 21, the movable frame 30 drives the plurality of second signal terminals 40 to be pressed downward synchronously, forming a plug-in connection with the first signal terminal 11. By setting the pressing structure on one side of the test fixture box body 10 and adopting a downward pressing method for plug-in connection, it will not affect the upper and lower molds of the test fixture, and avoids the traditional plug-in method causing the lower mold to lift up and affect the mold closing. The present application realizes plug-in connection by pressing from top to bottom, which can avoid affecting the test fixture and improve the plug-in efficiency.

[0023] Next, a top-bottom press-fitting and plugging device in this exemplary embodiment will be further described.

[0024] In the embodiment of the present application, the fixed frame 20 is disposed on one side of the test fixture housing 10 and is located directly above the first signal terminal 11. The fixed frame 20 is provided with a telescopic drive member 21, the telescopic end of which is downwardly directed toward the first signal terminal 11; wherein the first signal terminal 11 is located on an extended bottom plate on one side of the test fixture housing 10. A plurality of second signal terminals 40 are embedded in the movable frame 30, which is connected to the telescopic end of the telescopic drive member 21. The plurality of second signal terminals 40 correspond one-to-one with the plurality of first signal terminals 11. The extension of the telescopic drive member 21 drives the movable frame 30 downward, thereby pressing the second signal terminals 40 downward and plugging them into the first signal terminal 11, thereby connecting the test circuit of the test fixture housing 10. By pressing and plugging from top to bottom, the test fixture does not move during plugging; only the second signal terminal 40 needs to be moved downward, which can avoid affecting the mold closing of the test fixture and, in turn, the testing effect of the PCBA board. The telescopic drive member 21 is a telescopic cylinder having a stable telescopic stroke, and can be slowly pressed downward to achieve plugging, thereby avoiding damage to the plugging terminals due to excessive pressure being applied too quickly or too heavily.

[0025] As an example, the extended base plate is provided with a mounting plate 12, a plurality of the first signal terminals 11 are provided on the mounting plate 12, and the movable frame 30 is located squarely above the mounting plate 12. The mounting plate 12 is used to secure the first signal terminals 11 and is aligned with the movable frame 30, and also provides support and stability for the downwardly pressed second signal terminals 40.

[0026] As an example, the movable frame 30 includes a first plate 31 and a second plate 32 disposed in an upper and lower relationship. The first plate 31 and the second plate 32 are connected by a connecting column 33, and a plurality of second signal terminals 40 are embedded in the second plate 32. The top of the first plate 31 is connected to the telescopic end of the telescopic drive member 21. Because the second signal terminals 40 have a certain height, they are embedded in the second plate 32, leaving a certain height space between the second plate 32 and the first plate 31 to accommodate the height of the second signal terminals 40. The first plate 31 is connected to the telescopic end of the telescopic drive member 21. When the telescopic drive member 21 is extended or retracted, it drives the first plate 31 and the second plate 32 to move up and down synchronously, achieving press-fit insertion or removal.

[0027] As an example, the second plate body 32 is provided with a plurality of embedding holes 34, and a plurality of second signal terminals 40 are respectively embedded in the plurality of embedding holes 34 and fixed by locking members. The second signal terminals 40 are installed by the above-mentioned detachable connection method, which facilitates disassembly and maintenance, and also facilitates increasing or decreasing the number of second signal terminals 40. During installation, the second signal terminals 40 are installed from bottom to top. The plate body of the second signal terminal 40 is larger than the area of ​​the embedding hole 34. The plate body of the second signal terminal 40 is stuck at the bottom of the embedding hole 34, and the locking member is passed through the plate body of the second signal terminal 40 and locked and fixed with the second plate body 32 to facilitate installation. The above-mentioned locking member can be a locking bolt to facilitate disassembly and assembly.

[0028] As an example, a guide post 35 is provided between the second plate 32 and the mounting plate 12, and the second plate 32 is movably connected to the guide post 35. By providing the guide post 35 between the second plate 32 and the mounting plate 12, the up and down movement of the second plate 32 is along the axial direction of the guide post 35, ensuring that the second plate 32 does not deflect when pressed downward, thereby improving the insertion accuracy between the first signal terminal 11 and the second signal terminal 40.

[0029] As an example, a plurality of lead-out windows 24 are provided on one side of the fixing frame 20, each corresponding to the second signal terminal 40. The lead-out window 24 is detachably mounted with a wire lead-out member 22. The wire lead-out member 22 may be a double-horn socket, through which the signal terminals connected to each other are led out through wires to connect to the device.

[0030] As an example, the lead-out window 24 has a plurality of mounting holes 23 along its height direction, and the wire lead-out member 22 is mounted in the mounting holes 23. The wire lead-out member 22 is movably arranged on the fixing frame 20, and its height on the fixing frame 20 can be adjusted to facilitate adapting to plug-in positions at different heights, thereby improving practicality.

[0031] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0032] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device.
