Description

Technical Field

[0001] The present invention relates to the technical field of detection, in particular to a detection device and method for the connection strength of a plug. Background Art

[0002] The detection of the connection strength of a plug is a test for evaluating the connection firmness and reliability between the plug and the socket. When detecting, a horizontal plug and unplug force testing machine is usually used to detect the connection strength of the plug. Currently, when the horizontal plug and unplug force testing machine detects the connection strength of the plug, it faces many problems in terms of fixtures. On the one hand, special fixtures are required for plugs of different specifications and shapes, and the universality of the fixtures is poor. Frequent replacement of fixtures increases costs and time. On the other hand, during the plugging and unplugging process, the friction between the fixture and the surface of the plug is serious.

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0031] Embodiment 1

[0032] Referring to Figures 1 - 4 , which is the first embodiment of the present invention. This embodiment provides a detection device and method for the connection strength of a plug. The detection device and method for the connection strength of a plug include a detection component 100, which includes a body 101. A support rail 102 is fixed on the top of the body 101. A movable plate 103 is arranged on the top of the support rail 102. The movable plate 103 is clamped with the top of the support rail 102 and can reciprocate on the top of the support rail 102. A turntable 104 is arranged on one side of the support rail 102. The turntable 104 and the movable plate 103 are connected by a connecting rod. The two ends of the connecting rod are respectively rotatably connected to the top of the movable plate 103 and the top of the turntable 104. When the turntable 104 rotates, the movable plate 103 can be driven to reciprocate on the top of the support rail 102, so that the plug can be driven by the movable plate 103.

[0033] An installation frame 105 is arranged on the other side of the support rail 102. The installation frame 105 is used to support and fix the socket that cooperates with the plug, and can adjust the position and height of the socket, so as to adjust the plug and the socket to a centered state. The above are all prior arts, and this solution will not be elaborated here, and those skilled in the art can clearly understand the working principle.

[0034] A clamping component 200. The number of the clamping components 200 is two groups, which are respectively arranged on the movable plate 103 and the installation frame 105. The plug and the socket can be respectively clamped and fixed by the two groups of clamping components 200.

[0035] It includes a clamping member 201. The clamping member 201 includes a clamping plate 201a located above the movable plate 103. The number of the clamping members 201 is two groups, which are respectively located on both sides above the movable plate 103. A slide rail is fixed on the top of the movable plate 103. The clamping plate 201a is clamped on the top of the slide rail. Fixed blocks are fixed on both sides of the top of the slide rail. A threaded column is threadedly connected in the fixed block. The end of the threaded column is rotatably connected to the clamping plate 201a through a bearing. By rotating the threaded column, the clamping plate 201a can be driven to move, so that the clamping plate 201a can clamp and fix the plug or the socket. A slide rail is also fixed on one side of the installation frame 105, which is the same as the one on the top of the movable plate 103.

[0036] The clamping plate 201a is provided with a slot 201a-1, into which a push rod 201b is inserted. The number of the slots 201a-1 and the push rods 201b is multiple, and they are evenly distributed in a rectangle on one side of the clamping plate 201a. When clamping and fixing the plug, the clamping plate 201a is moved closer to the plug. At this time, the push rod 201b will contact the plug. According to the different shapes of the plug surface, as the clamping plate 201a continues to move, the push rods 201b at different positions will move into the interior of the slot 201a-1. When the clamping plate 201a stops moving, the push rod 201b will fit the shape of the plug and complete the clamping and fixing of the plug, and it can adapt to plugs of different shapes. Thus, there is no need to replace the fixture, thereby reducing costs and time.

[0037] A moving frame 201c is arranged inside the clamping plate 201a. The interior of the moving frame 201c is hollow. A plug 201d is fixed on one side of the moving frame 201c. The plug 201d communicates with the moving frame 201c. The number of the plugs 201d corresponds to that of the slots 201a-1. Only one group is shown in the drawing. When the clamping plate 201a stops moving, the moving frame 201c drives the plug 201d to move into the slot 201a-1 and block the interior of the slot 201a-1, making the interior of the slot 201a-1 in a sealed state. Thus, the push rod 201b cannot move, thereby preventing the fixing of the push rod 201b to the plug from becoming loose.

[0038] An extrusion assembly 300 is arranged on one side of the clamping plate 201a and includes a pushing member 301. The number of the pushing members 301 corresponds to that of the clamping plates 201a. The pushing member 301 includes a connecting pipe 301a fixed on one side of the moving frame 201c. The connecting pipe 301a communicates with the interior of the moving frame 201c.

[0039] A support frame 301b is fixed on one side of the connecting pipe 301a. Positioning blocks are fixed on both the top and bottom of the support frame 301b. A stabilizing column is fixed on one side of the clamping plate 201a. The stabilizing column is movably connected inside the positioning block, and the two cooperate to position the support frame 301b.

[0040] An airbag 301c is arranged inside the support frame 301b. The support frame 301b is used to support the airbag 301c. An air inlet pipe 301d is fixed on one side of the airbag 301c. The air inlet pipe 301d communicates with the airbag 301c. One side of the air inlet pipe 301d is fixedly connected to the support frame 301b through a connecting block.

[0041] As the number of times the plug is inserted and removed increases, the intake pipe 301d injects gas into the airbag 301c, causing the airbag 301c to expand. When the air pressure inside the airbag 301c is large enough, the gas inside it will enter the inside of the moving frame 201c through the connecting pipe 301a, and the moving frame 201c will transport the gas to the slot 201a-1, so that the gas exerts a thrust on the ejector rod 201b, and makes the position where the ejector rod 201b contacts the plug fit more tightly, thus avoiding the wear of the contact part between the plug surface and the ejector rod 201b, resulting in the loosening of their cooperation due to the lack of tightness.

[0042] Embodiment 2

[0043] Refer to Figures 3 - 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, a support ring 201e is fixed on the inner wall of the slot 201a-1, and a sealing block 201f is fixed at one end of the ejector rod 201b. The sealing block 201f is used to increase the sealing performance between the ejector rod 201b and the slot 201a-1. A first spring 201g is fixed on one side of the support ring 201e, and the support ring 201e is used to support and fix the first spring 201g. The other end of the first spring 201g is fixed to the sealing block 201f, and the first spring 201g exerts a thrust on the ejector rod 201b to keep it in an outward state all the time.

[0045] When the plug 201d enters the inside of the slot 201a-1, it will fit tightly with the support ring 201e, and the cooperation between the two can seal the inside of the slot 201a-1.

[0046] Specifically, an air inlet hole 201d-1 is opened on the plug 201d, and a baffle 201h is arranged inside the plug 201d. The baffle 201h is hinged to the inside of the plug 201d through a hinge plate, and the connection part between the two is sealed. A torsion spring is arranged on the hinge plate to exert a torsional force on the baffle 201h, so that the baffle 201h can always fit with the plug 201d and block the air inlet hole 201d-1.

[0047] A push column 201i is fixed at one end of the ejector rod 201b, and the number of the push columns 201i corresponds to that of the ejector rod 201b. If the ejector rod 201b moves due to the extrusion of the plug, it will drive the push column 201i to move at the same time, and the push column 201i will push the baffle 201h to open to one side, so as to release the blockage of the air inlet hole 201d-1. At this time, the gas inside the moving frame 201c can enter the inside of the slot 201a-1 through the opened air inlet hole 201d-1 and exert a thrust on the ejector rod 201b.

[0048] The ejector rod 201b that is not in contact with the plug and does not move will not be pushed by the gas, thereby avoiding unnecessary waste of gas and the situation where the ejector rod 201b that needs to be pushed by the gas receives insufficient thrust.

[0049] Specifically, the pressing assembly 300 further includes a blocking member 302. The blocking member 302 includes a mounting plate 302a fixed inside the connecting pipe 301a. The middle of the mounting plate 302a is hollow. One side of the mounting plate 302a is provided with a sealing plate 302b. The sealing plate 302b is hinged to the mounting plate 302a through a hinge plate, and a torsion spring is provided on the hinge plate to apply a torsional force to the sealing plate 302b, so that the sealing plate 302b can always be in close fit with the mounting plate 302a, and the connection between the two is sealed. The sealing plate 302b can only open unidirectionally into the moving frame 201c.

[0050] The sealing plate 302b is used to block the connecting pipe 301a to prevent gas from leaking from the inside of the support frame 301b into the inside of the connecting pipe 301a, so as to avoid the situation where the inside of the slot 201a-1 cannot be sealed.

[0051] When the air pressure inside the airbag 301c is too low, the air pressure inside it cannot offset the elastic force of the torsion spring on the sealing plate 302b. Therefore, the sealing plate 302b will not open. When the air pressure inside the airbag 301c is too high, it will offset the elastic force of the torsion spring on the sealing plate 302b. At this time, the gas will push the sealing plate 302b to open, and the gas can move into the support frame 301b. Then, the gas can be transported into the slot 201a-1 through the support frame 301b, and the gas applies a thrust to the ejector rod 201b, making the ejector rod 201b fit more closely to the surface of the plug.

[0052] Specifically, the pressing assembly 300 further includes a pressing member 303. The number of pressing members 303 is the same as that of the clamping plates 201a.

[0053] The pressing member 303 includes a piston 303a movably connected inside the air inlet pipe 301d. The piston 303a is hermetically connected to the inside of the air inlet pipe 301d. One side of the piston 303a is fixed with a fixed column 303b. One end of the fixed column 303b penetrates to the outside of the air inlet pipe 301d and is fixed with a force-bearing plate 303c. The movable plate 103 corresponds to the force-bearing plates 303c on the mounting frame 105. When the movable plate 103 moves, the two force-bearing plates 303c will contact and generate a mutual thrust, so that both of them can move.

[0054] On one side of the force-bearing plate 303c, a second spring 303d is fixed. The other end of the second spring 303d is fixed to the intake pipe 301d. The second spring 303d is used to reset the moved force-bearing plate 303c and the piston 303a. An intake groove 303a-1 is provided on the piston 303a. A stopper 303e is provided on one side of the piston 303a. The stopper 303e is also hinged to the piston 303a through a hinge plate, and a torsion spring is also provided on the hinge plate to apply a torsional force to the stopper 303e so that the stopper 303e can always fit with the piston 303a.

[0055] When the movable plate 103 is moving, the two force-bearing plates 303c come into contact and generate mutual thrust. At this time, the force-bearing plate 303c will drive the piston 303a to move into the intake pipe 301d. When the piston 303a is moving, it will inject gas into the airbag 301c. When the two force-bearing plates 303c are separated, a thrust is applied to them through the second spring 303d, and the two force-bearing plates 303c drive the piston 303a to move outside the intake pipe 301d. At this time, the stopper 303e will be opened under the pressure of the gas, and the gas generated when the piston 303a moves will enter one side of the piston 303a. When the piston 303a moves into the intake pipe 301d again, the gas can be injected into the airbag 301c again. As the movable plate 103 continues to move, the pressure inside the airbag 301c can be gradually increased.

[0056] Specifically, a fixing ring 303f is fixed inside the intake pipe 301d. A sealing plate 303g is provided on one side of the fixing ring 303f. The sealing plate 303g is also hinged to the fixing ring 303f through a hinge plate, and a torsion spring is provided on the hinge plate to closely fit the sealing plate 303g with the fixing ring 303f. The sealing plate 303g can only be opened unidirectionally towards the inside of the airbag 301c to block the gas stored inside the airbag 301c and prevent the gas from leaking out.

[0057] When the piston 303a injects gas into the airbag 301c, the pressure generated by the gas will open the sealing plate 303g to one side, so that the gas can enter the airbag 301c. When the piston 303a moves in the reverse direction, the sealing plate 303g will close to prevent the gas from leaking.

[0058] In the present invention, the connection manner of the hinge plate and the torsion spring is the same as that Figure 8 shown by the sealing plate 302b in

[0059] Embodiment 3

[0060] Referring to Figures 1 - 8 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0061] Specifically, the clamping assembly 200 further includes a rotating member 202. The number of the rotating members 202 corresponds to that of the moving frames 201c. The rotating member 202 includes a positioning post 202a fixed to one side of the moving frame 201c. One side of the clamping plate 201a is rotatably connected with a rotating sleeve 202b. The rotating sleeve 202b is rotatably connected with one side of the clamping plate 201a through a bearing. A fixed shaft 202c is fixed in the rotating sleeve 202b. A spiral groove 202a-1 is formed on the positioning post 202a. The fixed shaft 202c slides in the spiral groove 202a-1.

[0062] When the rotating sleeve 202b rotates, it will drive the fixed shaft 202c to slide in the spiral groove 202a-1. Through the cooperation of the two, the positioning post 202a can drive the moving frame 201c to move, and then the moving frame 201c can drive the plug 201d to block the slot 201a-1.

[0063] Specifically, a rotating rod 202d is fixed to one side of the rotating sleeve 202b, and a pressing rod 202e is fixed to the end of the rotating rod 202d.

[0064] The rotating rod 202d is inclined upward. The pressing rod 202e is in a telescopic form and is fixed to the rotating rods 202d on both sides respectively. By pressing down the pressing rod 202e to drive the rotating rod 202d to rotate, the rotating sleeve 202b can be driven to rotate by the rotating rod 202d.

[0065] Specifically, the clamping assembly 200 further includes a locking member 203. The locking member 203 includes a support block 203a fixed to one side of the clamping plate 201a. A limiting post 203b is inserted into the support block 203a. The limiting post 203b is movably connected in the support block 203a. A limiting hole 202b-1 is formed on the rotating sleeve 202b. The number of the limiting holes 202b-1 is two, and they are evenly distributed in an arc shape on the rotating sleeve 202b.

[0066] When the limiting post 203b is engaged with the limiting hole 202b-1, the rotating sleeve 202b can be locked, so as to lock the position of the moving frame 201c. Through the setting of the two limiting holes 202b-1, the moving frame 201c can be locked at different positions.

[0067] A stabilizing block 203c is fixed to the top of the limiting post 203b. A third spring 203d is fixed to the bottom of the stabilizing block 203c. The bottom end of the third spring 203d is fixed to the support block 203a. The stabilizing block 203c is used to fix the third spring 203d. A downward pulling force is applied to the stabilizing block 203c by the third spring 203d, and the limiting post 203b can be driven by the stabilizing block 203c to be more tightly engaged with the limiting hole 202b-1.

[0068] Specifically, the plug and socket to be detected are fixed by the clamping assembly 200 respectively, and the plug and the socket are in a centered state;

[0069] In the test machine control system, key parameters such as the insertion and extraction speed, insertion and extraction stroke, and number of tests are set, and appropriate parameter values are determined according to the plug type and relevant standards;

[0070] Start the turntable 104. The rotation of the turntable 104 will drive the plug to insert into the socket horizontally at a set speed. The insertion force data is collected in real time through the sensor until the plug is completely inserted into the socket;

[0071] The control system automatically records the peak values and change curves of the insertion force and extraction force during each insertion and extraction process, statistically analyzes the data of multiple tests, and calculates statistical quantities such as the average value and standard deviation to evaluate whether the connection strength of the plug meets the standard requirements.

[0072] During use, when detecting the plug, place the plug to be detected between the two clamping plates 201a, then rotate the threaded column to drive the clamping plate 201a to move, move the clamping plate 201a closer to the plug. At this time, the ejector rod 201b will contact the plug, and according to the different shapes of the plug surface, as the clamping plate 201a continues to move, the ejector rods 201b at different positions will move into the slot 201a-1. After the clamping plate 201a stops moving, the ejector rod 201b will fit the shape of the plug and complete the clamping and fixing of the plug.

[0073] At this time, pressing down the pressure lever 202e drives the rotating rod 202d to rotate, and then the rotating rod 202d can drive the rotating sleeve 202b to rotate. When the rotating sleeve 202b rotates, it will drive the fixed shaft 202c to slide in the spiral groove 202a-1. Through the cooperation of the two, the positioning column 202a can drive the moving frame 201c to move, and then the moving frame 201c can drive the plug 201d to block the slot 201a-1, making the inside of the slot 201a-1 in a sealed state, so that the ejector rod 201b cannot move, thus avoiding the loosening of the fixing of the ejector rod 201b to the plug, thereby completing the clamping and fixing of the plug and being able to adapt to plugs of different shapes. Furthermore, there is no need to replace the fixture, thus reducing costs and time. The fixing method of the socket is the same as above.

[0074] At this time, the turntable 104 can be started to drive the movable plate 103 to reciprocate on the top of the support track 102, so that the movable plate 103 can drive the plug to move, and the plug can be inserted into the socket reciprocally, thereby detecting the connection strength between the plug and the socket.

[0075] As the number of times the plug is inserted and removed increases, the intake pipe 301d injects gas into the airbag 301c, causing the airbag 301c to expand. When the air pressure inside the airbag 301c is large enough, the gas inside it will enter the inside of the moving frame 201c through the connecting pipe 301a, and the moving frame 201c will transport the gas to the slot 201a-1, so that the gas exerts a thrust on the ejector rod 201b, and makes the position where the ejector rod 201b contacts the plug fit more tightly, thereby avoiding wear at the contact part between the plug surface and the ejector rod 201b, resulting in the loosening of their cooperation due to the reduced tightness.
