Description

Technical Field

[0001] The present invention relates to the technical field of feeder terminal testing devices, and more particularly to a distribution automation feeder terminal testing conversion device. Background Art

[0002] The automated feeder terminal is one of the key devices in the distribution automation system, mainly used to monitor and control the feeder part of the distribution network. The feeder terminal collects various data from the field (such as voltage, current, switch status, etc.) and performs corresponding operations according to preset logic or remote instructions, thereby achieving effective management of the power network and rapid response to faults. Simply put, the feeder terminal is a control device installed on the utility pole, located below the voltage switch or voltage circuit breaker. It is shaped like a "big iron hat" and is used to control the voltage switch or voltage circuit breaker at the top. It also has a detection function. After the distribution automation feeder terminal is assembled, in order to ensure that it can work normally and meet the requirements of relevant technical specifications, a variety of performance tests are required.

[0003] Chinese patent application number 202311579963.7 discloses an intelligent auxiliary detection platform and method for the communication module of a cover-type feeder terminal. The platform comprises a detection mechanism for placing the cover-type feeder terminal; a connection mechanism hingedly provided at the front end of the detection mechanism for electrical connection to the cover-type feeder terminal; a control mechanism electrically connected to the connection mechanism within the detection mechanism; and a host computer electrically connected to the control mechanism on one side of the detection mechanism. The platform can detect multiple feeder terminals.

[0004] Chinese patent application number 202222798506.4 discloses an intelligent terminal testing system, which includes a feeder terminal, an energy meter calibrator, and an analog relay protection tester. Several feeder terminals are connected to several analog relay protection testers in a one-to-one correspondence to form several test branches. After the several test branches are connected in parallel to the same energy meter calibrator, multi-channel control of the energy meter calibrator and the analog relay protection tester is achieved. Multiple feeder terminals can be tested simultaneously, improving the test efficiency of the feeder terminals and shortening the test time. This device has the effect of improving detection efficiency.

[0005] Currently, the following problems still exist when testing distribution automation feeder terminals:

[0006] 1. The current testing method is primarily a "one-to-one" approach, meaning that one performance test device is connected to only one feeder terminal. When testing the same feeder terminal for different test items, each method requires a different wiring method. For example, when testing the voltage and current of an FTU, a wiring method for testing voltage and current must be used; when testing the FTU's action logic, a wiring method different from the one for testing voltage and current must be used. This requires frequent cable switching when performing different performance tests on the same feeder terminal. This frequent cable switching increases testing time, reduces testing efficiency, and can lead to incorrect connections.

[0007] 2. After testing one feeder terminal, you need to unplug the cable at the bottom of the feeder terminal and connect it to the wiring port at the bottom of the next feeder terminal. Since there are many cables that need to be connected, the efficiency of plugging and unplugging the cables is low, which affects the conversion efficiency between the feeder terminals. In addition, manual plugging may result in loose interfaces, affecting the accuracy of the test.

[0008] Therefore, it is necessary to propose a distribution automation feeder terminal test conversion device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0043] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in various different configurations.

[0044] Depend on Figures 1 to 14 The invention provides a support platform 101 and a bottom plate 102 located above the support platform 101. The support platform 101 is a support structure for supporting the bottom plate 102 at the top and the internal rotating drum 107 and other structures. The top of the bottom plate 102 is evenly spaced with batch racks 103 for grouping the feeder terminals 105. Each group performs different steps. In this embodiment, the batch racks 103 are set into three groups, which can perform multiple group tests. For example, when the first group performs the first test, the second group has been tested. After the first test, the second test is being carried out, and the third group has passed the two tests and can be removed from the placement slot 104 and replaced with a new feeder terminal 105. The interior of the batch rack 103 is provided with a placement slot 104 for placing the feeder terminal 105. Each batch rack 103 is provided with multiple placement slots 104. Each placement slot 104 can place a feeder terminal 105. The placement slots 104 are arranged at equal intervals. The interior of the bottom plate 102 is provided with a connection component. The connection component can be connected to the wiring port at the bottom of the feeder terminal 105, and then connected to the control device 106 through the connection of the bottom cable, so as to perform testing. A positioning component is provided above the connection component to place the feeder terminal 105 in the placement slot 104. At this time, there is no need to adjust the position angle of the feeder terminal 105. The positioning component can automatically position it, so as to facilitate the connection between the feeder terminal 105 and the terminal 204. The connection component cooperates with the interface at the bottom of the feeder terminal 105. The feeder terminal 105 is shaped like a hat, and multiple cable connectors are provided at the bottom to connect with the internal circuit. This is an existing device and will not be described in detail here. The terminal 204 on the connection component corresponds to the interface at the bottom of the feeder terminal 105, which is convenient for connection. A fixing component for fixing the feeder terminal 105 is provided in the batch rack 103. The fixing component is used to fix the feeder terminal 105 to prevent the feeder terminal 105 from being displaced or shaken, resulting in poor connection.

[0045] One side of the support platform 101 is connected to a control device 106, and a detection device is installed inside the control device 106, which can perform various detections on the feeder terminal 105. A rotating drum 107 is rotatably connected to the support platform 101. The rotating drum 107 can realize the connection of different joints by rotating, eliminating the need for manual connection and avoiding connection errors. The rotating drum 107 is externally connected to a rotation drive structure, and the external rotation drive structure is used to drive the rotating drum 107 to rotate, thereby connecting different joints. One side of the control device 106 is connected to a connecting column 1 extending into the rotating drum 107. 08. The rotating drum 107 and the connecting post 108 are connected via a conductive slip ring. Since the rotating drum 107 needs to rotate while the control device 106 is fixed, the two are connected via a conductive slip ring. Multiple connecting assemblies are evenly spaced on the exterior of the rotating drum 107. A second plug strip 409 that mates with the connecting assemblies is provided on the outer wall of the rotating drum 107. A connecting frame 109 connects the connecting assemblies to the batch rack 103. The interior of the connecting frame 109 is used to install cables, which connect the male plug strips 404 in the connecting assemblies to the corresponding terminal posts 204. A drive assembly is connected to one end of the rotating drum 107, which is connected to the fixed assembly.

[0046] When in use, it is necessary to connect the cable connector to the interface at the bottom of the feeder terminal 105 to perform the test of the feeder terminal 105. However, since there are many cables that need to be connected, the operation process is cumbersome and the work efficiency is low. The following provides a structure that facilitates the connection of the cable connector to the interface at the bottom of the feeder terminal 105: Specifically, refer to Figure 3 and Figure 4The bottom plate 102 is connected to a center cover 201 located at the bottom of the placement slot 104. The center cover 201 is provided with a through hole for the terminal 204 to pass through, so that the terminal 204 extends upward and is connected to the interface at the bottom of the feeder terminal 105. The bottom plate 102 is provided with a lifting cavity 202 located below the center cover 201. The connecting assembly includes a lifting plate 203 located in the lifting cavity 202. The lifting plate 203 is located in the lifting cavity 202 and can move up and down. The top of the lifting plate 203 is connected to a plurality of terminals 204 corresponding to the bottom interface of the feeder terminal 105. A through-hole for a terminal 204 is provided. The center cover 201 has a certain thickness. When the lifting plate 203 is at the bottom, the terminal 204 does not escape from the through-hole and remains within it. The top of the terminal 204 is lower than the upper surface of the center cover 201. A lead screw 205, threadedly connected to the lifting plate 203, is rotatably connected within the lifting chamber 202. A first motor 206 is connected to the bottom of the lead screw 205. The first motor 206 drives the lifting plate 203 up and down via the lead screw 205. When the lifting plate 203 moves upward, the top terminal 204 is driven to insert into the bottom interface of the feeder terminal 105. In another embodiment, a sprocket is mounted on the bottom of each lead screw 205 within the same batch frame 103. A single first motor 206 is provided on one side of the batch frame 103. The output end of the first motor 206 is also connected to a sprocket. Multiple sprockets are connected by a chain, allowing a single first motor 206 to drive multiple lead screws 205 to rotate.

[0047] During use, the interface at the bottom of the feeder terminal 105 may not correspond to the terminal 204, which may affect the connection between the terminal 204 and the interface and affect the connection efficiency. The following provides a method for positioning the feeder terminal 105 so that the position of each feeder terminal 105 is the same, which is convenient for connecting the connector: Specifically, refer to Figures 3 to 5The outer wall of the feeder terminal 105 is connected with a boss 207. The boss 207 on the feeder terminal 105 is a structure for connecting to a power supply device. When the feeder terminal 105 is used in the outside world, the power supply device supplies power to it. A battery and other structures are provided inside to continue to control the normal use of the feeder terminal 105 when the power is off. The positioning component includes an inner ring 208 and an outer ring 209 located on the outer ring surface of the center cover 201. The inner ring 208 and the outer ring 209 are positioned The area between the center cover 201 and the bottom plate 102 can rotate around the center cover 201. The top of the inner ring 208 is connected to a first clamping block 210, and the first clamping block 210 rotates along with the inner ring 208. The top of the outer ring 209 is connected to a second clamping block 211, and the second clamping block 211 rotates along with the outer ring 209. The first clamping block 210 and the second clamping block 211 correspond to the boss 207 on the feeder terminal 105. When the inner ring 208 rotates along with the outer ring 209, the first clamping block 210 and the second clamping block 211 correspond to the boss 207 on the feeder terminal 105. When the inner ring 208 and the outer ring 209 rotate in opposite directions, they will come into contact with the boss 207 on the outer wall of the feeder terminal 105, and then drive it to rotate. By clamping the boss 207 on both sides, the feeder terminal 105 is positioned. The interior of the second clamping block 211 is provided with a receiving cavity 212 for accommodating the first clamping block 210. The first clamping block 210 can enter the second clamping block 211, reducing the volume of the two and avoiding the feeder terminal 105 being located in a dead angle between the two clamping blocks when placed. After the feeder terminal 105 is placed on the center cover 201, the inner ring 208 and the outer ring 209 rotate in opposite directions, which will cause the first clamping block 210 and the second clamping block 211 at the top to come into contact with the boss 207 on the outer wall of the feeder terminal 105, thereby driving the feeder terminal 105 to rotate, so that each feeder terminal 105 can be rotated to a specified angle, thereby facilitating the insertion of the terminal 204 at the bottom into the interface.

[0048] Since the inner ring 208 and the outer ring 209 need to rotate in opposite directions at the same time, otherwise the feeder terminal 105 cannot be positioned. The following provides a structure for driving the inner gear ring 213 and the outer gear ring 214 to rotate in opposite directions: the bottom of the inner ring 208 is connected to the inner gear ring 213, and the inner gear ring 213 can drive the inner ring 208 to rotate. The bottom of the outer ring 209 is connected to the outer gear ring 214, and the outer gear ring 214 can drive the outer ring 209 to rotate. A second motor 215 is connected to the base plate 102, and the output end of the second motor 215 is connected to a driving gear 216 that is meshed with the inner gear ring 213 and the outer gear ring 214. When the output end of the second motor 215 drives the driving gear 216 to rotate, the outer gear ring 214 and the inner gear ring 213 on both sides will rotate in different directions, thereby realizing the effect of the inner ring 208 and the outer ring 209 rotating in opposite directions. Since the diameters of the inner gear ring 213 and the outer gear ring 214 are different, the rotation conditions will also be different, but this does not affect their positioning, and finally the position of the boss 207 is fixed by clamping.

[0049] It should be noted that when the first clamping block 210 and the second clamping block 211 rotate, the boss 207 will come into contact with the first clamping block 210 or the second clamping block 211. No matter which one it comes into contact with, the feeder terminal 105 will be driven to rotate through the boss 207.

[0050] After placing the feeder terminal 105 on the center cover 201, the axis of the feeder terminal 105 needs to be positioned so that the two clamping blocks can drive the feeder terminal 105 to rotate and position through the boss 207. Otherwise, the misalignment of the two axes will affect the positioning effect. The following provides a structure that allows the two axes to coincide with each other: Specifically, refer to Figure 6 and Figure 7The center cover 201 is provided with a first annular groove 301 inside, and the first annular groove 301 is used to accommodate multiple raised plates 306, so that the inner ring 208 can drive the multiple raised plates 306 to rotate in the first annular groove 301. The top of the center cover 201 is provided with multiple first sliding grooves 302, and the multiple first sliding grooves 302 are staggered with the through holes on the center cover 201. The staggered arrangement makes the rotating wheel 305 and the terminal 204 not affect each other. The first sliding groove 302 is connected to the first annular groove 301, and the interior of the first sliding groove 302 is slidably connected with a moving block 303, and the moving block 303 and the first The sliding grooves 302 are connected by springs. The springs are in a compressed state and are used to push the moving block 303 in a direction away from the axis of the center cover 201. After the feeder terminal 105 is placed on the center cover 201, multiple rotating wheels 305 will extend outward from the axis, fixing the feeder terminal 105 from the inside. The bottom of the feeder terminal 105 is recessed upward to accommodate the movement of the rotating wheels 305. The top of the moving block 303 is connected to a tilting frame 304. The top of the tilting frame 304 is rotatably connected to the rotating wheels 305. The tilting frame 304 enables the rotating wheels 305 to be at the same height, which facilitates the positioning of the feeder terminal 105.

[0051] When in use, the feeder terminal 105 is placed on the center cover 201, and multiple rotating wheels 305 position the feeder terminal 105 from the inside so that the axes of the two coincide. When the first clamping block 210 and the second clamping block 211 drive the boss 207 to rotate, the feeder terminal 105 will rotate along the axis of the center cover 201, so that the positions of all feeder terminals 105 are the same, which is convenient for the connection of the bottom cable.

[0052] When in use, multiple rotating wheels 305 need to be located on the side close to the axis to form a smaller circle, which is convenient for the placement of the feeder terminal 105. The following provides a structure for driving multiple rotating wheels 305 close to the axis: multiple raised plates 306 are connected to the inner ring surface of the inner ring 208, and the multiple raised plates 306 are not on the same plane and are staggered. The moving block 303 is connected to a driven roller 307 in contact with the raised plate 306. When the raised plate 306 contacts the driven roller 307, it will squeeze the moving block 303 to move in the direction of the axis of the center cover 201. At this time, the spring between the moving block 303 and the first sliding groove 302 will be compressed. Each of the raised plates 306 is arranged corresponding to the moving block 303 and forms a group, and multiple groups of vertical directions The plurality of raised plates 306 are staggered, specifically, a single moving block 303 and a single raised plate 306 form a group, and the plurality of raised plates 306 rotate with the inner ring 208; when the first clamping block 210 is located in the accommodating cavity 212, the raised plates 306 of each group come into contact with the driven roller 307 on one side of the moving block 303, thereby squeezing it, and the spring in the first sliding groove 302 is compressed, so that the plurality of rotating wheels 305 are located in a direction close to the axis, which facilitates placing the feeder terminal 105 on the center cover 201; when the inner ring 208 and the outer ring 209 rotate, the raised plates 306 of each group disengage from the driven roller 307 on one side of the moving block 303, and the spring resets at this time, pushing the moving block 303 in a direction away from the axis, thereby fixing the feeder terminal 105 from the inside.

[0053] When the lifting plate 203 moves upward, the terminal 204 will be inserted into the wiring port at the bottom of the feeder terminal 105. Since there is no structure on the top to support the feeder terminal 105, the feeder terminal 105 will shake. The following provides a structure for clamping and fixing the feeder terminal 105; specifically, refer to Figure 8 The fixing assembly includes a protruding frame 308, a fixing plate 309 arranged at equal intervals on the protruding frame 308, and the fixing plate 309 is connected to the protruding frame 308 at equal intervals. The fixing plate 309 is also located at the top of the placement groove 104, and the height corresponds to the bend on the feeder terminal 105. The outer wall of the feeder terminal 105 is provided with a bend. Figure 4The interior of the batch rack 103 is provided with symmetrically arranged oil chambers 310, and the symmetrical oil chambers 310 are located on both sides of the multiple placement slots 104. The oil chambers 310 are parallel to the axial direction of the batch rack 103 and are located on both sides of the placement slots 104. The protruding rack 308 is slidably connected to the oil chamber 310, and one end of the fixed plate 309 is located in the placement slot 104. The oil chamber 310 is externally connected to an oil supply device, and through the external oil supply device, the protruding rack 308 can move in the oil chamber 310, thereby pushing the fixed plate 309 out of the oil chamber 310. At this time, the fixed plate 309 will come into contact with the bend on the feeder terminal 105, fix the feeder terminal 105, and prevent the terminal 204 from affecting the feeder terminal 105 when it is lifted upward.

[0054] When the feeder terminal 105 performs various tests, it is necessary to switch the connected cables and the plug-in and plug-out conversion of the cable connectors, which not only affects the efficiency of the test, but also may cause connector connection errors when there are too many cables. The following provides a structure that can switch the connection connectors: Specifically, refer to Figures 11 to 13The connecting assembly includes a housing 401, a first connecting block 402 slidably connected to the housing 401, the first connecting block 402 and the housing 401 are connected by a spring, the number of connecting assemblies is the same as that of the batch rack 103, the terminal 204 in the batch rack 103 is connected to the corresponding connecting assembly through the connecting rack 109, and multiple connecting assemblies are arrayed at equal intervals on the outside of the rotating drum 107, the housing 401 is arranged toward the rotating drum 107, and the internal spring pushes the first connecting block 402 to press against the outside of the rotating drum 107. On the wall, the first connecting block 402 is connected to the side of the rotating drum 107 with a first plug row 403 arranged at equal intervals. The first plug row 403 is provided with a plug row male connector 404, which can be matched with the plug row female connector 410. When the plug row male connector 404 is inserted into the plug row female connector 410, the cable in the first connecting block 402 will be connected to the line in the rotating drum 107. The outer wall of the rotating drum 107 is provided with a first action part 405, a second action part 406 and a third action part 407 at equal intervals. 7, the first action part 405 is the first detection position. When the connecting component is connected to the first action part 405, it will be connected to the first detection device in the control device 106, thereby performing the first detection. The second action part 406 is the second detection position. When the connecting component is connected to the second action part 406, it will be connected to the second detection device in the control device 106, thereby performing the second detection. The third action part 407 is the disassembly position, which can be used to disassemble the feeder terminal 105 after the first and second detections. Remove it and replace it with a new feeder terminal 105. A second sliding groove 408 is provided in the first action part 405 and the second action part 406. A second plug-in row 409 is slidably connected in the second sliding groove 408. Since the third action part 407 needs to disassemble and assemble the feeder terminal 105, there is no need to set up a second plug-in row 409 structure. A plug-in row female socket 410 is provided on the second plug-in row 409, and the plug-in row female socket 410 can be plugged into the plug-in male connector 404 to connect the test cable.

[0055] During use, the first connecting block 402 can be pressed on the rotating drum 107 only when the connecting assembly corresponds to the position of the first action portion 405 or the second action portion 406. Otherwise, the connection joint structure will be affected. The following provides a structure in which the connection is made only when the corresponding positions are reached: Specifically, refer to Figure 12 and Figure 13, circular plates 501 are connected to the outer walls of the rotating drum 107 at both ends, and an action slide groove 502 is opened on the side of the circular plate 501 facing the first connecting block 402, and the action slide grooves 502 on the two circular plates 501 are both set toward the rotating drum 107, and strip grooves 503 are opened at both ends of the outer shell 401, and the strip grooves 503 are set toward the axis of the rotating drum 107, so that the first connecting block 402 can only move toward or away from the position of the rotating drum 107, and the two ends of the first connecting block 402 are connected to moving columns 504 located in the action slide groove 502, and the moving column 504 passes through the strip groove 503 and is located in the action slide groove 502. The end of the moving column 504 is connected with a universal ball, which is also called a bull's eye ball, which is used to reduce friction when moving in the action slide groove 502.

[0056] The action slide 502 is provided with a vertical portion 505 and an inclined portion 506, and the inclined portion 506 is inclined. The vertical portion 505 and the inclined portion 506 are located in the first action portion 405 and the second action portion 406, and the vertical portion 505 is arranged toward the rotating drum 107. When the connecting component is located in the first action portion 405 or the second action portion 406, the first connecting block 402 will move into the vertical portion 505 through the movable columns 504 on both sides. At this time, the spring between the shell 401 and the first connecting block 402 is reset, pressing the first connecting block 402 against the outer wall of the rotating drum 107; when the rotating drum 107 continues to rotate, the movable column 504 will enter the inclined portion 506, and at this time the first connecting block 402 can be moved upward, and at this time the male connector 404 of the socket 410 of the socket is disengaged.

[0057] When the circular plate 501 rotates, the male connector 404 of the extension strip has not yet completely separated from the female connector 410. At this time, the movable columns 504 on both sides of the first connecting block 402 will be located in the inclined portion 506, and the axis between the male connector 404 of the extension strip and the female connector 410 will be separated and misaligned, which will cause damage to the connecting joint. The following structure is provided to avoid damage: the second extension strip 409 and the second sliding groove 408 are connected by a spring. When in use, the spring pushes the second extension strip 409 in the direction of rotation of the rotating drum 107. When the circular plate 501 rotates and the female connector 410 and the male connector 404 of the extension strip have not yet been disconnected, the movable columns 504 on both sides of the first connecting block 402 will be located in the inclined portion 506. Through the compression of the spring in the second sliding groove 408, the angle change between the female connector 410 and the male connector 404 of the extension strip is adapted. When the two are separated, the spring resets. It should be noted that when the second plug-in bar 409 slides in the second sliding groove 408, it moves around the axis of the drum 107. In another embodiment, a guide groove is provided in the second sliding groove 408, and the guide groove is arc-shaped and coincides with the axis of the drum 107.

[0058] It should be noted that the rotation direction of the drum 107 is opposite to the arrangement direction of the first action part 405, the second action part 406 and the third action part 407. Figure 13 In the embodiment, the rotation direction of the rotating drum 107 is clockwise, and the arrangement direction of the first action part 405, the second action part 406 and the third action part 407 is counterclockwise. At this time, the connecting component will come into contact with the first action part 405, the second action part 406 and the third action part 407 in sequence. At the same time, when the circular plate 501 rotates, the movable column 504 will first enter the vertical part 505 and then enter the inclined part 506; when the connecting component corresponds to the first action part 405 or the second action part 406 or the third action part 407 on the outer wall of the rotating drum 107, it will stop for a period of time. The detection requires a certain amount of time to facilitate the detection. After the detection is completed, it rotates again.

[0059] Since the third action part 407 does not need to be tested, the first connecting block 402 is located on the side away from the rotating drum 107, so that the male plug 404 and the female plug 410 are not connected together. At this time, the extension frame 308 in the oil chamber 310 should be in a retracted state to facilitate the feeder terminal 105 to be taken out of the placement slot 104. The following provides a structure for driving the extension frame 308 to retract into the oil chamber 310: Specifically, refer to Figure 9 and Figure 14The driving assembly includes a cam plate 508 and a plurality of driven oil tanks 507. The number of the driven oil tanks 507 is the same as the number of the batch racks 103. When the driven oil tank 507 is squeezed, the hydraulic oil inside will enter the oil chamber 310, thereby driving the extension rack 308 in the oil chamber 310 to extend. Specifically, the spring between the extension rack 308 and the oil chamber 310 is in a stretched state. The cam plate 508 is connected to one end of the rotating drum 107 and can rotate together with the rotating drum 107. The positions of the plurality of driven oil tanks 507 correspond to the first action part 405, the second action part 406 and the third action part 407. A recessed portion 509 is provided on one side of the cam plate 508. The recessed portion 509 is located at a position corresponding to the third action part 407. When the recessed portion 509 rotates to a certain driven oil tank When at 507, since the spring between the extension frame 308 and the oil chamber 310 is in a stretched state, the hydraulic oil in the oil chamber 310 will be squeezed back into the driven oil tank 507. At this time, the fixed plate 309 will also retract into the oil chamber 310. In another embodiment, a spring is also provided in the driven oil tank 507, which is used to push the piston of the driven oil tank 507 outward, so that the roller at the output end can come into contact with the cam plate 508. Multiple driven oil tanks 507 are fixed on the support platform 101 through a supporting structure. The protruding end of the driven oil tank 507 is set toward the cam plate 508, and the protruding end is rotatably connected to a roller in contact with the cam plate 508. The roller is used to reduce friction during sliding connection. The driven oil tank 507 and the oil chamber 310 are connected by an oil pipe, and the oil pipe is used to move the hydraulic oil back and forth.

[0060] Specifically, a first detection device and a second detection device are installed in the control device 106. The first detection device and the second detection device can perform different tests respectively, and multiple rows of feeder terminals 105 can perform different tests. The first detection device is electrically connected to the socket 410 in the first action part 405, and the first detection device is connected to the socket 410 in the first action part 405 through a conductive slip ring. The second detection device is electrically connected to the socket 410 in the second action part 406, and the second detection device is connected to the socket 410 in the second action part 406 through a conductive slip ring.

[0061] Specifically, refer to Figure 9 A third motor 510 is connected to the top of the support platform 101. The third motor 510 is preferably a servo motor. The output end of the third motor 510 is connected to the rotating drum 107. The third motor 510 drives the rotating drum 107 to rotate.

[0062] When the present invention is in use, different feeder terminals 105 are placed in the placement slots 104 in the batch rack 103. The batch rack 103 is provided with multiple rows, and only three rows are shown in this figure. The second motor 215 rotates, and the multiple rotating wheels 305 extend outward to fix the feeder terminal 105 from the inside. Then, the first clamping block 210 and the second clamping block 211 come into contact with the boss 207 on the outer wall of the feeder terminal 105, driving the feeder terminal 105 to rotate, so that all the feeder terminals 105 rotate to a specified angle.

[0063] The third motor 510 drives the rotating drum 107 to rotate, which in turn drives the circular plate 501 and the cam plate 508 to rotate. When the cam plate 508 rotates to the third actuating portion 407, it squeezes the driven oil tank 507, causing the hydraulic oil in the driven oil tank 507 to enter the oil chamber 310. At this point, the extension frame 308 in the oil chamber 310 moves outward, driving the fixed plate 309 to press against the feeder terminal 105. The first motor 206 is then started, and its output drives the lifting plate 203 upward via the lead screw 205. At this point, the terminal 204 at the top of the lifting plate 203 is inserted into the interface at the bottom of the feeder terminal 105, connecting the cable.

[0064] At the position of the first action part 405 and the second action part 406, the first connection block 402 in the connection assembly will be pressed on the outer wall of the rotating drum 107, and the male plug 404 and the female plug 410 will be connected together, and the first and second tests will be performed respectively. After the test is completed, the rotation will continue, and the feeder terminal 105 that has passed the first test will undergo the second test. The feeder terminal 105 that has undergone the second test will lose the fixation of the fixing plate 309 and can be removed and replaced with a new feeder terminal 105, and this process will be repeated.

[0065] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
