Technical Field

[0001] The invention relates to the technical field of testing tooling, in particular to a switch module testing tooling. Background Art

[0002] A switch means "switch" and is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch, and other common switches include telephone voice switches, fiber optic switches, etc. A switch module is a switch chip.

[0003] The utility model with publication number CN219266344U discloses a switch module test fixture, which includes a test base plate, a driving mechanism and a positioning mechanism; wherein a plug-in portion that is plugged and matched with the switch module is fixedly arranged on the test base plate; the driving mechanism is used to drive the switch module to approach or move away from the plug-in portion; the positioning mechanism includes a positioning plate and a reset device; the positioning plate is horizontally located just above the plug-in portion and can be translated up and down relative to the test base plate, a positioning groove for installing the switch module is provided on the top surface of the positioning plate, and a through hole for the plug-in portion to pass through is provided on the positioning plate. In the above application document, by arranging the positioning plate just above the plug-in portion, A positioning groove and a through hole are provided on the top surface of the positioning plate. When the switch module is tested, the switch module can be horizontally positioned on the positioning plate through the positioning groove. The switch module is pressed down by the driving mechanism, and the switch module drives the positioning block toward the test base plate.

It is more troublesome to take out the switch module after the test is completed, which delays the process when operating a large number of switch modules. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a switch module testing tool to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a switch module testing tool, including a test body, the top of the test body is fixedly connected to a support frame, the inner side of the support frame is fixedly connected to a support plate, the front end of the support plate is fixedly connected to a mounting frame, the front end of the support plate is fixedly mounted with a hydraulic cylinder through the mounting frame, the output end of the hydraulic cylinder is fixedly connected to a movable plate, the inner side of the support frame is fixedly connected to a sliding rod, the movable plate is slidably connected to the sliding rod, the front end of the test body is provided with an external joint, the top of the test body is provided with a test positioning mechanism, and the bottom of the movable plate is provided with a buffer pressing mechanism; the test positioning mechanism includes a limit rod, a plug-in portion and a switch module, the bottom of the limit rod is connected to the test The top of the body is fixedly connected, the surface of the limit rod is slidably connected with a positioning plate, the surface of the limit rod is sleeved with a reset spring, the plug-in part is electrically connected to the top of the test body, the top of the plug-in part is provided with a plug-in groove and a round groove, the top of the positioning plate is provided with a positioning groove, the bottom of the positioning groove is provided with an opening, the inner bottom of the positioning groove is provided with an embedding groove, the inner bottom of the embedding groove passes through and is slidably connected with an ejector rod, the top of the ejector rod is fixedly connected with a pressure plate, the bottom of the ejector rod is fixedly connected with a circular plate, the top of the circular plate is fixedly connected with a compression spring, the end of the compression spring away from the circular plate is fixedly connected to the bottom of the positioning plate, the bottom of the switch module is provided with an insertion part, and the side of the positioning plate is provided with a deceleration mechanism.

[0006] According to the above technical solution, the size of the positioning groove is equal to the size of the switch module, and the size of the opening is smaller than the size of the switch module. The positioning groove is used to position the switch module, and the small size of the opening prevents the switch module from falling from the positioning groove.

[0007] According to the above technical solution, in the initial state, one-half of the switch module is located in the positioning groove, and the bottom of the switch module conflicts with the top of the pressure plate. When the switch module moves downward, it presses down the pressure plate, causing the ejector rod to move downward.

[0008] According to the above technical solution, the diameter of the embedding groove is equal to the diameter of the pressure plate, and the diameter of the circular groove is larger than the diameter of the circular plate. When the pressure plate moves downward, it will be embedded in the embedding groove, and when the circular plate moves downward, it will enter the circular groove.

[0009] According to the above technical solution, the deceleration mechanism includes a connecting frame, a rotating rod, a limiting rod and a vertical plate. The connecting frame and the limiting rod are fixedly connected to the side of the positioning plate. Torsion springs are provided at both ends of the rotating rod.

The bottom of the vertical plate is fixedly connected to the top of the test body. The side of the vertical plate is fixedly connected to a deceleration block.

[0010] According to the above technical solution, the limiting rod is L-shaped as a whole, and one end of the limiting rod away from the side of the positioning plate is close to the bottom of the contact block, so that the limiting rod prevents the contact block from deflecting downward.

[0011] According to the above technical solution, the lateral length of the contact block is greater than the lateral distance from the surface of the rotating rod to the surface of the speed reduction block. The material of the speed reduction block is rubber. When the contact block moves vertically, it will contact the speed reduction block. When the contact block and the rubber speed reduction block are squeezed, a large resistance will be generated.

[0012] According to the above technical solution, the buffer pressing mechanism includes a pressing block, the top of the pressing block is fixedly connected to the bottom of the movable plate, a groove is provided at the bottom of the pressing block, a buffer spring is provided inside the groove, a buffer block is slidably connected inside the groove through the buffer spring, and a reminder component is provided at the top of the groove.

[0013] According to the above technical solution, the reminder component includes a pneumatic chamber and a reminder airbag. The pneumatic chamber passes through and is fixedly connected to the inner top of the groove. The internal piston at one end of the pneumatic chamber is slidably connected to a piston rod, and the bottom of the piston rod is fixedly connected to a counterweight block. The other end of the pneumatic chamber passes through and is fixedly connected to an air pipe, and the reminder airbag is fixedly connected to the top of the movable plate. The end of the air pipe away from the pneumatic chamber passes through and is fixedly connected to the reminder airbag.

[0014] According to the above technical solution, one third of the buffer block protrudes from the lower pressure block in the initial state, and the reminder airbag is in a contracted state in the initial state. When the lower pressure block moves downward, the buffer block will first contact the switch module. When the piston rod moves upward relative to the air pressure chamber, the air pressure in the air pressure chamber will enter the reminder airbag to expand it.

[0015] The present invention provides a switch module testing tool. It has the following beneficial effects:

[0016] (1) The present invention sets a test positioning mechanism so that when the switch module needs to be tested, the switch module can be placed in the positioning groove at the top of the positioning plate for preliminary positioning. Then, the hydraulic cylinder is turned on to press down the switch module so that the top plate moves downward and the bottom insertion part of the switch module is inserted into the plug-in groove at the top of the plug-in part before the test can be carried out. The operation is simple and the positioning is accurate. After the test is completed and the hydraulic cylinder is no longer pressed down, the positioning plate will automatically bounce up and recover. At the same time, the switch module will also bounce up so that one half of it protrudes from the positioning groove, which is convenient for taking out and testing the next switch module.

[0017] (2) The present invention provides a deceleration mechanism so that when the positioning plate automatically bounces upward to recover after the test, the contact block, torsion spring, deceleration block and other components will cooperate to slow down the speed and amplitude of the positioning plate when it bounces upward to recover, thereby preventing the positioning plate from bouncing upward to recover due to excessive speed and amplitude causing vibrations and causing damage to the switch module on which the test has been completed.

[0018] (3) The present invention sets a buffer pressing mechanism so that when the hydraulic cylinder is opened to drive the movable plate to move downward, it will drive the pressing block to move downward to perform the pressing work. When the pressing block moves downward, the buffer block will first contact the switch module. At this time, the cooperation between the buffer block and the buffer spring can achieve a buffering effect to prevent damage to the switch module during the pressing. When the switch module is pressed down, the counterweight block, the air pressure chamber, the air pipe and other components will cooperate to cause a warning airbag to collide, thereby reminding the operator to stop pressing down to prevent excessive pressing.

The bottom of the limit rod 81 is fixedly connected to the top of the test body 1. The surface of the limit rod 81 is slidably connected to a positioning plate 83. The surface of the limit rod 81 is sleeved with a reset spring 82. The plug-in portion 84 is electrically connected to the top of the test body 1. The top of the plug-in portion 84 is provided with a plug-in groove 85 and a circular groove 86. The top of the positioning plate 83 is provided with a positioning groove 87. The bottom of the positioning groove 87 is provided with an opening 88. The size of the positioning groove 87 is equal to the size of the switch module 814, and the size of the opening 88 is smaller than the size of the switch module 814. The positioning groove 87 is used to position the switch module 814. The opening 88 is small in size so that the switch module 814 will not fall from the positioning groove 87. The inner bottom of the positioning groove 87 is provided with an embedding groove 89. The inner bottom of the embedding groove 89 penetrates and is slidably connected with an ejector rod 810. The top of the ejector rod 810 is fixedly connected with a pressure plate 811. In the initial state, one-half of the switch module 814 is located in the positioning groove 87, and the bottom of the switch module 814 conflicts with the top of the pressure plate 811. When the switch module 814 moves downward, it presses the pressure plate 811 downward, so that the ejector rod 810 moves downward. The bottom of the ejector rod 810 is fixedly connected with a circular plate 812. The diameter of the embedding groove 89 is equal to the diameter of the pressure plate 811. 6 is larger than the diameter of the circular plate 812. When the pressure plate 811 moves downward, it will be embedded in the embedding groove 89. When the circular plate 812 moves downward, it will enter the circular groove 86. The top of the circular plate 812 is fixedly connected with a compression spring 813. The end of the compression spring 813 away from the circular plate 812 is fixedly connected to the bottom of the positioning plate 83. An insertion portion 815 is provided at the bottom of the switch module 814. A deceleration mechanism 9 is provided on the side of the positioning plate 83. The deceleration mechanism 9 includes a connecting frame 91, a rotating rod 92, a limiting rod 95 and a vertical plate 96. The connecting frame 91 and the limiting rod 95 are fixedly connected to the side of the positioning plate 83. Torsion springs 93 are provided at both ends of the rotating rod 92. The rotating rod 92 is connected to the positioning plate 83 through the torsion springs 93 at both ends. The connecting frame 91 penetrates and is rotatably connected. A contact block 94 is fixedly connected to the surface of the rotating rod 92. The limiting rod 95 is L-shaped as a whole, and the end of the limiting rod 95 away from the side of the positioning plate 83 is close to the bottom of the contact block 94. The limiting rod 95 prevents the contact block 94 from deflecting downward. The bottom of the vertical plate 96 is fixedly connected to the top of the test body 1. The side of the vertical plate 96 is fixedly connected to a speed reduction block 97. The lateral length of the contact block 94 is greater than the lateral distance from the surface of the rotating rod 92 to the surface of the speed reduction block 97. The material of the speed reduction block 97 is rubber. When the contact block 94 moves vertically, it will contact the speed reduction block 97. When the contact block 94 and the rubber speed reduction block 97 are squeezed, a large resistance will be generated. ;

[0032] When in use, the switch module 814 is placed in the positioning groove 87 at the top of the positioning plate 83 for preliminary positioning. At the beginning, the bottom of the switch module 814 contacts the top of the pressure plate 811, and half of the switch module 814 protrudes out of the positioning groove 87. When testing is required, the switch module 814 is pressed down to make it completely enter the positioning groove 87. The insertion portion 815 at the bottom of the switch module 814 protrudes from the bottom of the positioning plate 83 through the opening 88, and the pressure plate 811 is pressed down into the embedding groove 89. The ejector rod 810 and the circular plate 812 move downward, the compression spring 813 is stretched, and then the switch module 814 is pressed down again. At this time, the positioning plate 8 The whole switch module 814 will move downward along the limit rod 81, and the reset spring 82 will be compressed. At this time, the bottom insertion part 815 of the switch module 814 will be inserted into the insertion groove 85 at the top of the plug-in part 84, and the circular plate 812 and the ejection rod 810 will enter the circular groove 86 without being affected. The bottom insertion part 815 of the switch module 814 will be inserted into the insertion groove 85 at the top of the plug-in part 84 before the test can be carried out. When the switch module 814 is no longer pressed down after the test, the reset spring 82 will rebound and drive the positioning plate 83 to move upward to restore, and the bottom insertion part 815 of the switch module 814 will be separated from the insertion groove 85 at the top of the plug-in part 84, and the compression spring 813 will rebound. The circular plate 812 and the ejector rod 810 are driven to move upward and restore. The ejector rod 810 moves upward and restores to drive the pressure plate 811 to move upward to lift the switch module 814 upward. At this time, half of the switch module 814 protrudes out of the positioning groove 87 again, which is convenient for the operator to take out and test the next switch module 814. The positioning is accurate, which saves time and effort when testing a large number of switch modules 814. In the process of the positioning plate 83 moving downward, the connecting frame 91, the rotating rod 92 and the contact block 94 are also driven to move downward. The contact block 94 moves downward and contacts with the speed reduction block 97 on the side of the vertical plate 96. At this time, the contact block 94 is subjected to a force below. The upward deflection will not cause excessive squeezing and resistance with the deceleration block 97, and then the torsion spring 93 drives the restoration. When the subsequent reset spring 82 rebounds and drives the positioning plate 83 to move upward and restore, the contact block 94 contacts the deceleration block 97 again. At this time, the contact block 94 cannot deflect downward due to the existence of the limiting rod 95. The contact block 94 will be squeezed with the deceleration block 97 to generate resistance. The resistance generated slows down the speed and amplitude of the positioning plate 83 when it bounces upward to restore, preventing the positioning plate 83 from bouncing upward and restoring at too large a speed and amplitude to cause shock and damage to the switch module 814 on which the test has been completed, making the overall operation more stable.

[0033] See also Figure 1-10On the basis of the above embodiment, in another embodiment of the present invention, the buffer pressing mechanism 10 includes a pressing block 101, the top of the pressing block 101 is fixedly connected to the bottom of the movable plate 7, a groove 102 is provided at the bottom of the pressing block 101, a buffer spring 103 is provided inside the groove 102, a buffer block 104 is slidably connected to the inside of the groove 102 through the buffer spring 103, a reminder component 105 is provided at the top of the inner part of the groove 102, the reminder component 105 includes an air pressure chamber 1051 and a reminder airbag 1055, the air pressure chamber 1051 passes through and is fixedly connected to the inner top of the groove 102, a piston at one end of the air pressure chamber 1051 is slidably connected to a piston rod 1052, and the piston A counterweight block 1053 is fixedly connected to the bottom of the rod 1052, and an air pipe 1054 is passed through and fixedly connected to the other end of the air pressure chamber 1051. The reminder airbag 1055 is fixedly connected to the top of the movable plate 7. The end of the air pipe 1054 away from the air pressure chamber 1051 passes through and is fixedly connected to the reminder airbag 1055. In the initial state, one third of the buffer block 104 protrudes from the lower pressure block 101. The reminder airbag 1055 is in a contracted state in the initial state. When the lower pressure block 101 moves downward, the buffer block 104 will first contact the switch module 814. When the piston rod 1052 moves upward relative to the air pressure chamber 1051, the air pressure in the air pressure chamber 1051 will enter the reminder airbag 1055 to expand it.

[0034] When in use, when it is necessary to press down the switch module 814 in the positioning groove 87 at the top of the positioning plate 83, the hydraulic cylinder 5 can be opened to drive the movable plate 7 to move downward along the slide rod 6. The downward movement of the movable plate 7 will drive the pressing block 101 to move downward. The downward movement of the pressing block 101 will drive the buffer block 104 to first contact the switch module 814. At this time, the cooperation of the buffer block 104 and the buffer spring 103 can play a buffering effect to prevent the switch module 814 from causing damage. Subsequently, the pressing block 101 and the buffer block 104 continue to press down the switch module 814 to complete the subsequent positioning, and When block 814 is fully compressed, the buffer block 104 will move upward relative to the groove 102. The upward movement of the buffer block 104 will contact the counterweight block 1053 and drive the counterweight block 1053 to move upward relative to the air pressure chamber 1051. The upward movement of the counterweight block 1053 drives the piston rod 1052 to move upward relative to the air pressure chamber 1051. The upward movement of the piston rod 1052 relative to the air pressure chamber 1051 will squeeze the air pressure in the air pressure chamber 1051 so that the air pressure enters the warning airbag 1055 through the air pipe 1054. At this time, the warning airbag 1055 expands to remind the operator to stop pressing down to prevent excessive downward pressure.
