[0068] Referring to Figures 1-2 The embodiment provides a television mainboard 10 socket 11 testing device for automatically testing the television mainboard 10, avoiding manual plugging and unplugging of the screen line to the socket 11, and improving testing efficiency and quality.

[0069] In some embodiments, the television mainboard 10 socket 11 testing device can comprise a base 1. The base 1 is provided with a mounting area for mounting the mainboard 10 to be tested. The base 1 is arranged on the ground as a base of the testing device. The top surface of the base 1 can be a plane to stably position and mount the mainboard 10.

[0070] In some embodiments, the mounting area can be located on the top surface of the base 1, and a positioning column can be arranged in the mounting area to cooperate with a positioning hole on the mainboard 10, so that the mainboard 10 can be positioned and mounted, and the mainboard 10 can be arranged at the same position on the mounting area, facilitating subsequent testing of the mainboard 10.

[0071] In some embodiments, a positioning frame can also be arranged in the mounting area on the base 1. The outline of the positioning frame is matched with the outline of the mainboard 10 to be tested, so that the mainboard 10 to be tested can be mounted in the positioning frame for positioning and mounting.

[0072] In some embodiments, the television mainboard 10 socket 11 testing device can further comprise a docking seat 2 for docking with the socket 11 of the mainboard 10 to be tested, avoiding manual plugging and unplugging of the screen line for testing, and improving testing efficiency.

[0073] Referring to Figures 3-4 Specifically, the docking seat 2 can comprise a positioning floating plate 20. The positioning floating plate 20 is arranged above the mounting area, and the positioning floating plate 20 is provided with a docking area corresponding to the socket 11 of the mainboard 10 to be tested. When the positioning floating plate 20 moves towards the base 1, the docking area can dock with the socket 11 of the mainboard 10 to be tested, so as to position the positioning floating plate 20 and the mainboard 10 to be tested.

[0074] In some embodiments, the docking seat 2 can further comprise a fixing seat 21. The fixing seat 21 is arranged on the side of the positioning floating plate 20 away from the base 1, and the fixing seat 21 and the positioning floating plate 20 are elastically connected, so that the positioning floating plate 20 can move up and down relative to the fixing seat 21.

[0075] In some embodiments, the docking seat 2 can further comprise a signal testing piece 22, which is used to dock with the socket 11 of the mainboard 10 and transmit the test signal of the mainboard 10 to an external test system, so as to test the mainboard 10. The signal testing piece 22 can comprise a signal adapter plate 220, which is fixed to the fixed seat 21 and moves with the fixed seat 21. The signal adapter plate 220 is used to be electrically connected with the external test system. The signal testing piece 22 can further comprise a test probe 221, which is connected with the signal adapter plate 220. The test probe 221 is used to be plugged with the socket 11 of the mainboard 10, so as to obtain the test signal of the mainboard 10 and transmit the test signal to the signal adapter plate 220. Then, the test signal is transmitted to the external test system through the signal adapter plate 220, so as to test the mainboard 10.

[0076] In some embodiments, the docking area of the positioning floating plate 20 can be provided with a through probe hole 200 corresponding to the position of the test probe 221. The test probe 221 can be extended from the probe hole 200, so as to be plugged with the socket 11 of the mainboard 10.

[0077] In some embodiments, the docking seat 2 can further comprise a lifting mechanism 3, which is connected with the fixed seat 21. The lifting mechanism 3 is used to drive the fixed seat 21 to move up and down.

[0078] When the mainboard 10 is tested, the lifting mechanism 3 can drive the fixed seat 21 to move downward, so as to drive the positioning floating plate 20 and the fixed seat 21 to move towards the base 1, thereby driving the docking area of the positioning floating plate 20 to dock with the socket 11 of the mainboard 10 to be tested. Due to the elastic connection between the positioning floating plate 20 and the fixed seat 21, the positioning floating plate 20 is subjected to the upward force of the socket 11, so as to move upward, thereby driving the test probe 221 to move downward relative to the positioning floating plate 20. The test probe 221 is extended from the probe hole 200 and docks with the socket 11. After the test is completed, the docking seat 2 is driven by the lifting mechanism 3 to move upward, so that the force of the socket 11 of the mainboard 10 on the positioning floating plate 20 disappears. The positioning floating plate 20 is driven to move downward relative to the fixed seat 21 by the elastic force, so that the test probe 221 is retracted from the probe hole 200. The test probe 221 can be protected, so as to improve the test safety.

[0079] In some embodiments, the positioning floating plate 20 can be provided with a positioning ring barrier 201 around the docking area. The positioning ring barrier 201 can be annular and protrude on the bottom surface of the positioning floating plate 20. The profile of the positioning ring barrier 201 corresponds to the profile of the socket 11 of the mainboard 10 to be tested. Therefore, when the mainboard 10 is tested, the positioning ring barrier 201 is sleeved on the socket 11 of the mainboard 10 to position the socket 11 of the mainboard 10, so that the docking seat 2 and the socket 11 of the mainboard 10 are accurately docked, improving the testing accuracy and efficiency.

[0080] In some embodiments, a guide inclined surface can be provided between the inner side wall and the bottom wall of the positioning ring barrier 201 to facilitate fine adjustment of the relative position of the two when docking, so as to facilitate the positioning ring barrier 201 to be sleeved on the socket 11 of the mainboard 10.

[0081] In some embodiments, the docking area of the positioning floating plate 20 can also be inwardly recessed to form a recess. The profile of the recess corresponds to the profile of the socket 11 of the mainboard 10, so that when docking, the socket 11 can be inserted into the recess to accurately position the positioning floating plate 20 and the socket 11 of the mainboard 10.

[0082] Continuing to refer to Figures 4-7 In some embodiments, the fixed seat 21 can include a fixed seat body 210. The fixed seat body 210 is the main structure of the fixed seat 21. The fixed seat body 210 is provided with a guide hole 211 corresponding to the position of the probe hole 200. The signal adapter plate 220 is arranged on the fixed seat body 210. The test probe 221 extends into the guide hole 211, so that the displacement of the test probe 221 is guided and limited by the guide hole 211, improving the movement accuracy of the test probe 221.

[0083] In some embodiments, the signal testing member 22 can also include a needle sleeve 222 connected with the signal adapter plate 220. The needle sleeve 222 is internally provided with a space for accommodating the test probe 221. The needle sleeve 222 covers the test probe 221 to protect it. One end of the test probe 221 is electrically connected with the signal adapter plate 220. The other end of the test probe 221 extends out of the needle sleeve 222. Part of the structure of the test probe 221 is located in the needle sleeve 222.

[0084] Correspondingly, the top surface of the fixed seat body 210 can also be provided with a second accommodating groove 212. The guide hole 211 is provided on the bottom surface of the second accommodating groove 212. The signal adapter plate 220 is fixed on the top of the fixed seat body 210. The needle sleeve 222 is accommodated in the second accommodating groove 212 to limit the needle sleeve 222, so that the needle sleeve 222 and the test probe 221 are stably connected on the fixed seat body 210. The structure of the needle sleeve 222 and the fixed seat body 210 is more compact.

[0085] In some embodiments, the signal adapter plate 220 can be placed horizontally on the top of the fixing base 210. The top of the fixing base 210 can also be provided with an inner recessed limiting groove, and the signal adapter plate 220 is arranged in the limiting groove to reduce the thickness of the fixing base 210 and make the fixing base 210 compact. The signal adapter plate 220 and the fixing base 210 can be fixedly connected by a screw fastener, or the signal adapter plate 220 and the limiting groove can be interference fit to clamp the signal adapter plate 220 in the limiting groove.

[0086] It should be noted that the test probe 221 can be provided in multiple branches and arranged in the needle sleeve 222 in the length direction. Correspondingly, the probe hole 200 and the guide hole 211 are also provided with multiple holes, and the multiple test probes 221 are arranged one by one in the guide hole 211 and the probe hole 200 to be inserted into the multiple contacts on the socket 11 of the mainboard 10.

[0087] In some embodiments, the positioning floating plate 20 is provided with a first accommodating groove 202 on the side away from the base 1, the probe hole 200 penetrates the groove bottom of the first accommodating groove 202, the groove opening of the first accommodating groove 202 is upwardly arranged, and the first accommodating groove 202 is arranged in position with the second accommodating groove 212 in the up-down direction.

[0088] In some embodiments, the fixing base 21 further comprises a protruding portion 213 protruding from the bottom of the fixing base 210. The protruding portion 213 can be matched with the shape of the first accommodating groove 202, and the protruding portion 213 is embedded in the first accommodating groove 202, so that the fixing base 21 and the positioning floating plate 20 are tightly connected, and the protruding portion 213 can guide the movement of the positioning floating plate 20 relative to the fixing base 21.

[0089] In some embodiments, the protruding portion 213 can be a rectangular block extending along the length direction of the fixing base 210, and the cross-sectional shape of the first accommodating groove 202 can be a corresponding rectangle to guide by the protruding portion 213 itself.

[0090] In some embodiments, the bottom surface of the fixing base 210 can also be provided with an annular convex rib 214, and the profile of the annular convex rib 214 can correspond to the profile of the edge of the positioning floating plate 20, so that the edge of the positioning floating plate 20 can be placed in the annular convex rib 214, and the horizontal direction of the positioning floating plate 20 is limited by the cooperation of the protruding portion 213 and the first accommodating groove 202, so that the positioning floating plate 20 can only move in the up-down direction relative to the fixing base 210.

[0091] In some embodiments, the positioning floating plate 20 can be provided with a first fixing hole 203 extending in the up-down direction, and the fixing seat body 210 can be provided with a second fixing hole 215 corresponding to the first fixing hole 203. The first fixing hole 203 and the second fixing hole 215 are oppositely arranged, and the inner diameters of the two can be consistent or inconsistent.

[0092] In some embodiments, the docking seat 2 can further include a first connecting column 23. The first connecting column 23 is a columnar structure, and the first connecting column 23 is arranged in the first fixing hole 203 and the second fixing hole 215. One end of the first connecting column 23 extends into the second fixing hole 215 from the first fixing hole 203 and is fixedly connected with the second fixing hole 215, so that the first connecting column 23 and the fixing seat body 210 are fixedly connected. The end of the first connecting column 23 away from the fixing seat body 210 can be provided with a first limiting portion 230, and the first limiting portion 230 can be arranged on the side of the positioning floating plate 20 facing the base 1, for limiting the positioning floating plate 20 from being separated from the first connecting column 23. The size of the first limiting portion 230 is greater than the size of the first fixing hole 203, so that the first limiting portion 230 is limited to the outside of the first fixing hole 203.

[0093] It should be noted that by arranging the first limiting portion 230, the first connecting column 23 and the positioning floating plate 20 can be movably connected in the up-down direction, and the position of the positioning floating plate 20 moving downward is limited by the first limiting portion 230, preventing it from being separated from the first connecting column 23.
