The first guide rail assembly 200 is mounted on the first mounting frame 100, and the first guide rail assembly 200 has a first board card guide rail 220, which is in sliding connection with the test board card 40 and extends towards the connector 60. The second guide rail assembly 300 is arranged on the side of the first guide rail assembly 200 away from the connector 60 and is detachably connected with the first mounting frame 100, and the second guide rail assembly 300 has a second board card guide rail 330, which is in sliding connection with the test board card 40 and coincides with the extension direction of the first board card guide rail 220.
[0046] From the above, when the length of the test board card 40 to be plugged on the connector 60 increases, the second guide rail assembly 300 which is detachably connected with the first mounting frame 100 can be mounted on the first mounting frame 100, so that the second board card guide rail 330 coincides with the extension direction of the first board card guide rail 220, thereby the test board card 40 can be inserted into the connector 60 under the guidance of the first board card guide rail 220 and the second board card guide rail 330. In this way, the length of the guide rails for guiding the test board card 40 can be increased, thereby adapting to the test board card 40 with increased length. In this way, the patch panel 10 can adapt to test board cards 40 with different lengths as needed, thereby improving the compatibility of the patch panel 10. In addition, by detachably connecting the second guide rail assembly 300 with the first mounting frame 100, when the length of the test board card 40 changes, the second guide rail assembly 300 can be conveniently detached and mounted, thereby reducing the operation difficulty.
[0047] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 10As shown, the first mounting frame 100 includes a first mounting plate 110 and a second mounting plate 120, the first mounting plate 110 and the second mounting plate 120 are arranged in parallel, and two ends of the first guide rail assembly 200 are fixedly connected with the first mounting plate 110 and the second mounting plate 120 respectively; one end of the second guide rail assembly 300 is detachably connected with the first mounting plate 110 or the second mounting plate 120. Thus, when the length of the test board card 40 corresponding to the connector 60 at different positions increases, the second guide rail assembly 300 can be installed on the first mounting plate 110 or the second mounting plate 120 to make the second board card guide rail 330 corresponding to the connector 60 coincide with the extension direction of the first board card guide rail 220, so as to adapt to the installation of the test board card 40 after the length increases. Thus, the adaptation range of the plug-in box 10 can be improved, and the compatibility of the test equipment can be improved.
[0048] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 、 Figure 10 As shown, the first guide rail assembly 200 is provided in plurality, and the plurality of first guide rail assemblies 200 are arranged along the extension direction of the first board card guide rail 220.
[0049] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 、 Figure 10 As shown, the first guide rail assembly 200 includes a first support frame 210, and two ends of the first support frame 210 are fixedly connected with the first mounting plate 110 and the second mounting plate 120 respectively. The first support frame 210 is arranged in pairs, and the two first support frames 210 arranged in pairs are parallel to each other, and two ends of the first board card guide rail 220 are connected with the two first support frames 210 arranged in pairs respectively.
[0050] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 、 Figure 10 As shown, a plurality of first clamping holes 211 are uniformly arranged on the first support frame 210 along the extension direction of the first support frame 210, and two ends of the first board card guide rail 220 are clamped and connected with two corresponding first clamping holes 211 on the two first support frames 210 arranged in pairs respectively. Thus, the position of the first board card guide rail 220 on the first support frame 210 can be adjusted according to the position of the connector 60, and the adaptation range of the plug-in box 10 can be improved.
[0051] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 、 Figure 10As shown, the first board guide rail 220 is provided in multiple, arranged along the extension direction of the first support frame 210. In this way, each first board guide rail 220 can correspond to one connector 60, so that multiple test boards 40 can be guided, and each test board 40 can be plugged into one connector 60.
[0052] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 、 Figure 10 As shown, the first support frame 210 is provided in multiple pairs, and each pair of first support frames 210 is arranged in a direction perpendicular to the plane in which the pair of first support frames 210 is located. Each pair of first support frames 210 is arranged in a group of two, and the test board 40 is located between the two pairs of first support frames 210 in each group, and the two side edges of the test board 40 are respectively connected to the first board guide rails 220 on the two pairs of first support frames 210. In this way, the test board 40 can be guided on both sides, thereby improving the stability of the test board 40.
[0053] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 9 As shown, the second guide rail assembly 300 is provided in multiple, and one end of each of the multiple second guide rail assemblies 300 is detachably connected to the first mounting plate 110 or the second mounting plate 120. In this way, by providing multiple second guide rail assemblies 300, the second board guide rail 330 can be connected to the corresponding first board guide rail 220 at multiple positions. In this way, when the length of the test board 40 corresponding to the connector 60 at multiple positions increases, multiple test boards 40 of increased length can be simultaneously adapted. In this way, the adaptation range of the patch panel 10 can be improved, and the compatibility of the test equipment can be improved.
[0054] In some embodiments, one end of each of the multiple second guide rail assemblies 300 is detachably connected to the first mounting plate 110 or the second mounting plate 120, and the second board guide rail 330 of each of the multiple second guide rail assemblies 300 is arranged along the extension direction of the first board guide rail 220. In this way, when one second guide rail assembly 300 cannot meet the length requirement of the test board 40, the number of second guide rail assemblies 300 can be increased to increase the adaptation range of the length of the test board 40, thereby improving the adaptation range of the patch panel 10 and improving the compatibility of the test equipment.
[0055] In some embodiments, the multiple second guide rail assemblies 300 can be partially detachably connected to the first mounting plate 110 and partially detachably connected to the second mounting plate 120. Alternatively, the multiple second guide rail assemblies 300 can be all detachably connected to the first mounting plate 110 or the second mounting plate 120.
[0056] In some embodiments, as shown in Figure 10 , Figure 2 , Figure 3 The second rail assembly 300 includes a first reinforcing plate 310 and a second support frame 320. The first reinforcing plate 310 is located between the first mounting plate 110 and the second mounting plate 120. One end of the second support frame 320 is detachably connected to the first mounting plate 110 or the second mounting plate 120, and the other end is fixedly connected to the first reinforcing plate 310. The second board card rail 330 is installed on the second support frame 320. In this way, by arranging the first reinforcing plate 310, the firmness and stability of the second support frame 320 can be improved, and the firmness and stability of the second board card rail 330 can be improved. In this way, the stability of the test board card 40 when inserted into the connector 60 under the guidance of the second board card rail 330 can be improved.
[0057] In some embodiments, as shown in Figure 9 , Figure 10 , Figure 2 The second support frame 320 is arranged in pairs, and the two second support frames 320 in the pair are parallel to each other. The two ends of the second board card rail 330 are respectively connected to the two second support frames 320 in the pair.
[0058] In some embodiments, as shown in Figure 3 , Figure 9 , Figure 10 The second support frame 320 is arranged in pairs, and the two second support frames 320 in the pair are parallel to each other. The two ends of the second board card rail 330 are respectively connected to the two second support frames 320 in the pair.
[0059] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 9 The second board card rail 330 is arranged in multiple, and is arranged along the extension direction of the second support frame 320. In this way, each second board card rail 330 can correspond to one connector 60, so that each test board card 40 can be guided, and multiple test board cards 40 can be plugged into one connector 60.
[0060] In some embodiments, as shown in Figure 10 , Figure 2 , Figure 3As shown, the second support frame 320 is provided in multiple pairs, and each pair of the second support frame 320 is arranged along a direction perpendicular to the plane in which the paired second support frame is located. Each pair of the second support frame 320 is arranged in a group of two, and the test board card 40 is located between the two pairs of the second support frame 320 in each group, and the two side edges of the test board card 40 are respectively connected to the second board card guide rail 330 on the two pairs of the second support frame 320. Thus, the test board card 40 can be guided on both sides, thereby improving the stability of the test board card 40.
[0061] In some embodiments, as shown in Figure 9 、 Figure 10 、 Figure 2 As shown, the second guide rail assembly 300 further includes a second reinforcing plate 340, and the second reinforcing plate 340 connects the first guide rail assembly 200 and the second guide rail assembly 300. Thus, by arranging the second reinforcing plate 340, the first guide rail assembly 200 and the second guide rail assembly 300 are connected, thereby improving the stability of the second guide rail assembly 300, and further improving the stability of the test board card 40 when the test board card 40 is inserted into the connector 60 under the guidance of the second board card guide rail 330.
[0062] In some embodiments, as shown in Figure 3 、 Figure 9As shown, the patch panel 10 further comprises a mounting assembly 400, which comprises a first fixing screw 420 and a first blocking piece 410. The first fixing screw 420 is screwed through the first mounting frame 100 and the second rail assembly 300. The first blocking piece 410 is mounted on the first mounting frame 100, located on at least one side of the first fixing screw 420 on the side of the first mounting frame 100 away from the second rail assembly 300, and extends away from the first mounting frame 100. The first fixing screw 420 is located in the mounting gap and screwed through the first mounting frame 100 and the second rail assembly 300. Thus, by screwing the first fixing screw 420 through the first mounting frame 100 and the second rail assembly 300, the second rail assembly 300 can be conveniently detachably connected to the first mounting frame 100. If the first blocking piece 410 is arranged only on the upper side of the first fixing screw 420, when the second rail assembly 300 is detached, the test equipment 1 is turned so that the first blocking piece 410 is below, so that the first fixing screw 420 can be loosened and fall on the first blocking piece 410, avoiding the first fixing screw 420 falling into a position difficult to take out. If the first blocking piece 410 is arranged on the lower side of the first fixing screw 420, the second rail assembly 300 can be directly detached, so that the first fixing screw 420 can be loosened and fall on the first blocking piece 410. If the first blocking piece 410 is arranged on both the upper and lower sides of the first fixing screw 420, when the second rail assembly 300 is detached, the first fixing screw 420 can be directly detached, and the first fixing screw 420 can be loosened and fall on the first blocking piece 410, avoiding the first fixing screw 420 falling into a position difficult to take out. Thus, the operation difficulty when the second rail assembly 300 is detached can be reduced.
[0063] In some embodiments, the second rail assembly 300 can also be detachably connected to the first mounting frame 100 by clamping, pasting, plug-in connection and the like, which is not limited.
[0064] In some embodiments, as Figure 10 , Figure 2As shown, the mounting assembly 400 further comprises a second blocking piece 430, which is mounted on the first mounting frame 100 at a position where the first blocking piece 410 faces the connector 60 and abuts against the first blocking piece 410. Since the test board card 40 is connected to the connector 60 through plugging, the connector 60 is located away from the operation side where the worker controls the operation of plugging the test board card 40 to the connector 60. By arranging the second blocking piece 430 on the side of the first blocking piece 410 facing the connector 60, the first fixing screw 420 can be prevented from flying out towards the first connector 60 when falling, i.e. the second blocking piece 430 can be prevented from falling on the operation side away from the worker. Thus, the first fixing screw 420 can fall on the position close to the operation side, and the first fixing screw 420 can be prevented from falling into the position difficult to take out, thereby reducing the operation difficulty when disassembling the second guide rail assembly 300.

As shown in FIG. 1, Figure 10 As shown in FIG. 1, the test device 1 further comprises a device plate 50, which is installed on the second mounting frame 20 and covers the second fixing screw 440. The device plate 50 is provided with a second operation hole 51 at a position corresponding to the second fixing screw 440. In this way, the second operation hole 51 can facilitate the operation of the second fixing screw 440, so as to facilitate the detachable connection between the second rail assembly 300 and the first rail assembly 200. Meanwhile, the second operation hole 51 provided on the device plate 50 covering the second fixing screw 440 can facilitate the worker to use a screwdriver or other tools to operate the second fixing screw 440 through the second operation hole 51.

[0071] Figure 2 FIG. 1 is a perspective view of the plug-in unit 10 in Embodiment 1. As shown in FIG. 1, Figure 3 FIG. 2 is a perspective view of the plug-in unit 10 in Embodiment 1. As shown in FIG. 2, Figure 9 Figure 10 As shown, the insertion box 10 includes a first mounting bracket 100, a first guide rail assembly 200, and a second guide rail assembly 300. The first mounting bracket 100 is used to be fixedly connected to the second mounting bracket 20, and the first guide rail assembly 200 and the second guide rail assembly 300 are mounted on the first mounting bracket 100 to guide the test board 40.
[0072] like Figure 2 As shown, the first mounting bracket 100 includes a first mounting plate 110 and a second mounting plate 120, which are arranged in parallel in a vertical state. A first guide rail assembly 200 and a second guide rail assembly 300 are installed between the first mounting plate 110 and the second mounting plate 120.
[0073] like Figure 3 As shown, the first guide rail assembly 200 includes a first support frame 210 and a first plate guide rail 220. The two ends of the first support frame 210 are fixedly connected to the first mounting plate 110 and the second mounting plate 120, respectively. The first support frames 210 are arranged in pairs, and the two pairs of first support frames 210 are parallel to each other. Specifically, the two pairs of first support frames 210 are arranged horizontally and perpendicular to the first mounting plate 110 and the second mounting plate 120.

Figure 2 As shown, the first board guide rail 220 is elongated, and the edge of the test board 40 can slide and connect with the first board guide rail 220. Multiple square first engagement holes 211 are evenly arranged on the first support frame 210 along its extension direction. The two ends of the first board guide rail 220 respectively engage and connect with the corresponding two first engagement holes 211 on two pairs of first support frames 210. After connection, the first board guide rail 220 is perpendicular to the first support frame 210. By adjusting the position of the first board guide rail 220 on the first support frame 210, the first board guide rail 220 can be positioned in the corresponding position of the connector 60. That is, the test board 40 can slide down towards the connector 60 under the guidance of the first board guide rail 220, allowing the test board 40 and the connector 60 to complete the insertion and removal connection.
[0075] like Figure 3 As shown, multiple first board guide rails 220 are provided and arranged along the extension direction of the first support frame 210. Thus, each first board guide rail 220 corresponds to a connector 60, thereby guiding multiple test boards 40 and allowing each test board 40 to be plugged into and disconnected from a connector 60.
[0076] like Figure 9As shown, the first support frame 210 is provided with 4 pairs, and the 4 pairs of first support frames 210 are arranged in layers along the vertical direction. The two pairs of first support frames 210 in the same group and the first card guide rail 220 thereon are symmetrically arranged up and down, the test board card 40 is located between the two pairs of first support frames 210 in the same group, and the two side edges of the test board card 40 are respectively connected with the first card guide rail 220 on the two pairs of first support frames 210 in the same group. Thus, the test board card 40 can be guided on both sides, thereby improving the stability of the test board card 40.
[0077] As shown, Figure 10 The first guide rail assembly 200 is provided with two groups, and the two groups of first guide rail assemblies 200 are arranged along the extension direction of the first card guide rail 220. Thus, the test board card 40 can be guided by the first card guide rail 220 in the two groups of first guide rail assemblies 200, thereby improving the stability of the test board card 40.
[0078] As shown, Figure 2 The second guide rail assembly 300 is arranged on the side of the first guide rail assembly 200 away from the connector 60 and is detachably connected with the first mounting plate 110. The second guide rail assembly 300 includes a first reinforcing plate 310, a second support frame 320, and a second card guide rail 330. The first reinforcing plate 310 is located between the first mounting plate 110 and the second mounting plate 120 and is parallel to the first mounting plate 110 and the second mounting plate 120. One end of the second support frame 320 is detachably connected with the first mounting plate 110, the other end is fixedly connected with the first reinforcing plate 310, and the second card guide rail 330 is installed on the second support frame 320. The second support frame 320 is arranged in pairs, and the two second support frames 320 in each pair are parallel to each other. Specifically, the two second support frames 320 in each pair are horizontally arranged and perpendicular to the first mounting plate 110 and the first reinforcing plate 310.
[0079] As shown, Figure 3 The second card guide rail 330 is in the shape of a long strip, and the edge of the test board card 40 can be connected with the second card guide rail 330. The second support frame 320 is uniformly provided with a plurality of square second clamping holes 321 along the extension direction of the second support frame 320, and the two ends of the second card guide rail 330 are respectively clamped and connected with the corresponding two second clamping holes 321 on the two second support frames 320 in each pair, and after connection, the second card guide rail 330 is perpendicular to the second support frame 320. By adjusting the position of the second card guide rail 330 on the second support frame 320, the extension direction of the second card guide rail 330 can be made to coincide with the extension direction of the corresponding first card guide rail 220, so that the second card guide rail 330 is located at the corresponding position of the connector 60, that is, the test board card 40 can be guided by the second card guide rail 330 and the first card guide rail 220 to slide to the connector 60, so that the test board card 40 and the connector 60 are connected.
[0080] As shown in Figure 9 , the second board guide rail 330 is provided with multiple, along the extension direction of the second support frame 320. Thus, each second board guide rail 330 can correspond to a connector 60, so that multiple test board cards 40 can be guided, and each test board card 40 can be plugged into a connector 60.
[0081] As shown in Figure 10 , the second support frame 320 is provided with 4 pairs, and the two pairs of second support frames 320 in the same group are arranged in the vertical direction. The two pairs of second support frames 320 in the same group and the second board guide rails 330 thereon are arranged symmetrically up and down, the test board card 40 is located between the two pairs of second support frames 320 in the same group, and the two side edges of the test board card 40 are respectively connected with the second board guide rails 330 on the two pairs of second support frames 320 in the same group. Thus, the test board card 40 can be guided on both sides, so that the stability of the test board card 40 can be improved.
[0082] As shown in Figure 2 , the second guide rail assembly 300 further comprises a second reinforcing plate 340, and the second reinforcing plate 340 connects the first guide rail assembly 200 and the second guide rail assembly 300. Specifically, one end of the second reinforcing plate 340 is fixedly connected with the second support frame 320, and the other end is fixedly connected with the first support frame 210 through the second fixing screw 440. Thus, the stability of the second guide rail assembly 300 can be improved, and the stability of the test board card 40 when being inserted into the connector 60 under the guidance of the second board guide rail 330 can be improved.
[0083] Figure 3 One of the partial connection diagrams of the mounting assembly 400. As shown in Figure 9 , the plug-in box 10 further comprises a mounting assembly 400, and the mounting assembly 400 comprises a first blocking piece 410, a first fixing screw 420 and a second blocking piece 430. The first fixing screw 420 is screwed through the first mounting plate 110 and the second support frame 320, so that the second guide rail assembly 300 is detachably connected with the first mounting frame 100. The first blocking piece 410 is long and horizontally arranged, and two of them are mounted on the surface of the first mounting plate 110 away from the second guide rail assembly 300, one is located above the first fixing screw 420 screwed with the uppermost second support frame 320, and the other is located below the first fixing screw 420 screwed with the lowermost second support frame 320. The second blocking piece 430 is made of silk bubble cotton and is long and vertically arranged on the surface of the first mounting plate 110 away from the second guide rail assembly 300, and the two ends of the second blocking piece 430 are respectively connected with the two first blocking pieces 410 towards the connector 60.
[0084] Figure 10 This is the second partial connection diagram for installing component 400. (See diagram below.) Figure 2 As shown, the second mounting bracket 20 also includes a third mounting plate 21. The third mounting plate 21 is vertically arranged within the second mounting bracket 20, and the connector 60 and the insertion box 10 are located in the space on one side of the third mounting plate 21. The first blocking member 410 extends toward and connects to the third mounting plate 21, forming a rectangular space between the first mounting plate 110, the second mounting plate 120, the first blocking member 410, and the second blocking member 430. This space has an opening on the side away from the connector 60 (i.e., the side facing the test port 31). Thus, regardless of whether the test device 1 is placed upright or upside down, the first fixing screw 420 will only fall onto the first blocking member 410 after it falls, making it convenient for the operator to remove the first fixing screw 420 through the test port 31 and the opening of the rectangular space.
[0085] Figure 3 for Figure 9 A schematic diagram of the structure of the test equipment 1 after the upper cover plate 30 is removed; Figure 10 for Figure 2 A schematic diagram of the structure of test equipment 1 after removing the hidden cover 52. (See diagram below.) Figure 3 , Figure 9 As shown, the mounting assembly 400 also includes a second fixing screw 440, which passes through the first support frame 210 and is threadedly connected to the second reinforcing plate 340, fixing the second reinforcing plate 340 onto the first support frame 210, thus achieving a fixed connection between the second guide rail assembly 300 and the first guide rail assembly 200. The test device 1 also includes an equipment plate 50, which is used to mount equipment such as fans. The equipment plate 50 is mounted on the outside of the second mounting bracket 20, covering the second fixing screw 440. The equipment plate 50 has a second operating hole 51 at the position corresponding to the second fixing screw 440, allowing operators to use tools such as screwdrivers to operate the second fixing screw 440 through the operating hole 51. The equipment plate 50 also has a hidden cover 52, which is adapted to the second operating hole 51 for opening and closing the second operating hole 51.
[0086] Example 2
[0087] Figure 10 This is a schematic diagram of the connection between the insertion box 10 and the test board 40 in Example 2. Figure 2 As shown, the difference between the insertion box 10 in Embodiment 2 and the insertion box 10 in Embodiment 1 is that the test board 40 in the insertion box 10 of Embodiment 2 is shorter, and the first guide rail assembly 200 can meet the length requirement of the test board 40. Therefore, the second guide rail assembly 300 is not installed on the first mounting bracket 100 in Embodiment 2.
[0088] Embodiment 3
[0089] Figure 3 A structure diagram of the connection between the patch panel 10 and the test board card 40 in Embodiment 3 is shown. As shown, the patch panel 10 in Embodiment 3 is different from the patch panel 10 in Embodiment 1 in that the test board card 40 with a longer length is required to be arranged at both sides in the patch panel 10 (positions close to both ends of the first support frame 210), and the first guide rail assembly 200 cannot meet the length requirement of the test board card 40. Therefore, the second guide rail assembly 300 is arranged on both the first mounting plate 110 and the second mounting plate 120 in Embodiment 3.
