Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an automatic port plugging device for testing equipment. Background Art

[0002] Some devices, such as servers, need to be tested by special test equipment during production and use. During the test, the test equipment and the tested device need to be plugged in and matched with each other through a variety of connectors to establish data connection. In order to improve test efficiency, these connectors are automatically plugged in. However, when the number of connectors is large and the socket of the tested device is offset or tilted due to production assembly errors, automatic plugging can easily lead to improper plugging or damage to the socket of the tested device. Therefore, it is necessary to set the plug connector of the test equipment to an automatic centering structure; the existing automatic centering mechanism on the market usually connects the plug connector and the test equipment through the two ends of a spring, and a guide rod is passed through the center line of the elastic, and the peripheral wall of the plug connector and the guide rod has a gap for the plug connector to deviate, but with long-term use, the spring is prone to fatigue, resulting in the plug connector being unable to reset to the center, which in turn causes problems during automatic plugging, affecting the service life of the test equipment and the risk of damaging the tested device. Therefore, it is necessary to improve it. Utility Model Content

[0021] The present invention is further described below in conjunction with the accompanying drawings. When describing the embodiments of the present invention in detail, for the sake of convenience, the drawings showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. It should be noted that the drawings are simplified and use non-precise scales, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features; the terms "left", "right", "upper", "lower", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two components; it can mean a wireless connection or a wired connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] refer to Figures 1 to 4As shown, a port automatic plug-in device for a test equipment includes a mounting bracket 1, a plurality of parallel arranged plug-in components 2, and a linear device 3 for driving the plug-in components 2 to move back and forth along the plug-in direction; the plug-in component 2 includes a plug connector 21 arranged in sequence from front to back along the plug-in direction, a first seat body 22 for fixing the plug connector 21, a second seat body 23 arranged at intervals behind the first seat body 22, and a third seat body 24 arranged at intervals behind the second seat body 23 and connected to the linear device 3; the first seat body 22 and the second seat body 23 are connected by a first elastic connecting piece 25 arranged along the plug-in direction, and the deformation direction of the first elastic connecting piece 25 is the left and right direction, while the second seat body 23 and the third seat body 24 are connected by a second elastic connecting piece 26 along the plug-in direction, and the deformation direction of the second elastic connecting piece 26 is the up and down direction.

[0024] The first elastic connecting piece 25 can cause the first base body 22 to be offset in the left-right direction relative to the second base body 23, while the second elastic connecting piece 26 can cause the second base body 23 to be offset in the up-down direction relative to the third base body 24, thereby achieving automatic centering when the plug connector 21 is plugged in; and because the spacing between the first base body 22, the second base body 23, and the third base body 24 is relatively short, each elastic connecting piece is not only stronger than the spring in the prior art, but also has a shorter deformation length, so it will not fatigue after long-term use, which can extend the service life of the test equipment and avoid damage to the tested equipment.

[0025] A preferred solution, refer to Figure 2 In this embodiment, the first seat 22 and the second seat 23 are connected by first elastic connecting pieces 25 symmetrically arranged on the left and right sides of the centerline of the plug-in assembly 2. Furthermore, in this embodiment, the second seat 23 and the third seat 24 are connected by second elastic connecting pieces 26 symmetrically arranged on the upper and lower sides of the centerline of the plug-in assembly 2. Symmetrically arranging the first elastic connecting piece 25 or the second elastic connecting piece 26 on both sides not only further enhances the connection strength but also further improves the elastic reset capability. When the left and right sides or the front and back sides are far apart, the elastic connecting pieces can be installed symmetrically on both sides. When the two sides are close together, the elastic connecting piece can be installed on only one side.

[0026] A preferred solution, refer to Figure 3 and Figure 4 The plug-in device of this embodiment includes multiple sets of plug connectors 21 arranged in parallel at the front end of the first base 22. Typically, two or more sets of adjacent and identical plug connectors 21 are arranged at the front end of the same first base 22. This structure can simplify the structure of the plug-in device because the same plug sockets in the tested device have high consistency.

[0027] Further, refer to Figure 4 In this embodiment, multiple sets of parallel second elastic connecting pieces 26 are provided between the second base 23 and the third base 24, and each of the second elastic connecting pieces 26 located on the same side of the plug-in assembly 2 is fixed on the same plane of the second base 23 and the third base 24. Providing multiple sets of second elastic connecting pieces 26 can improve the connection strength between the second base 23 and the third base 24 and enhance the elastic reset capability. In another embodiment, multiple sets of parallel first elastic connecting pieces 25 are provided between the first base 22 and the second base 23, and each of the first elastic connecting pieces 25 located on the same side of the plug-in assembly 2 is fixed on the same plane of the first base 22 and the second base 23. Similarly, providing multiple sets of first elastic connecting pieces 25 can improve the connection strength between the first base 22 and the second base 23 and enhance the elastic reset capability. Usually when the left and right sides or the upper and lower sides are relatively wide apart, multiple sets of elastic connecting plates are usually set along the spacing direction to improve the connection strength and elastic reset ability. At this time, only the elastic connecting plate needs to be set on one side, and the elastic connecting plate is no longer required on the other side.

[0028] A preferred solution, refer to Figure 1 In this embodiment, the third base 24 of the plurality of plug-in assemblies 2 is fixed to a mounting plate 4, and the linear device 3 is connected to the mounting plate 4 to drive it to reciprocate along the plug-in direction. This can further simplify the structure of the plug-in device and reduce equipment costs.

[0029] In a preferred embodiment, the mounting bracket 1 of this embodiment is provided with multiple mounting plates 4 in parallel, each mounting plate 4 is provided with multiple sets of plug-in components 2, and each mounting plate 4 is driven by a separate linear device 3. Multiple devices under test can be tested simultaneously.

[0030] In a preferred embodiment, the linear device 3 comprises a cylinder 31 and a sliding pair 32 mounted on the mounting bracket 1 along the insertion direction. Specifically, the sliding pair 32 comprises a guide post and a guide sleeve. The cylinder 31 and the guide post are mounted on the mounting bracket 1, while the mounting plate 4 is fixed to the guide sleeve and the movable portion of the cylinder 31. The use of the cylinder 31 and the sliding pair 32 can reduce equipment costs. In other embodiments, the linear device 3 can also be a motor-driven linear device 3, etc. This is conventional technology and will not be described in detail.

[0031] A preferred solution, refer to Figures 2 to 4In this embodiment, each of the plug connectors 21 has a rigid guide member 211 at its front end. The front end of the guide member 211 is flush with or extends beyond the plug connector 21, and the front end of the guide member 211 has a guide cone that is smaller at the front and larger at the back. The rigid guide member 211 protects the plug connector 21 from damage and also makes it easier to insert into the socket of the device under test. Specifically, one type of guide member 211 includes a plug plate arranged parallel to at least two opposite sides of the plug connector 21; while another type of guide member 211 comprises a plurality of pins arranged parallel to and around the plug connector 21.

[0032] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
