Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a high-speed backplane connector. Background Art

[0002] A high-speed backplane connector is a connector used to connect a single board to a backplane in an electronic system. It can achieve efficient transmission of high-speed differential signals, single-ended signals, and high currents. In the fields of large-scale communication equipment, ultra-high-performance servers, supercomputers, industrial computers, high-end storage devices, etc., high-speed backplane connectors play a vital role, responsible for connecting core devices such as CPUs, storage devices, network interface cards, etc., to ensure that complex systems can process massive high-speed data streams through the connections, routings, and connectors on the backplane. Existing high-speed backplane connectors have poor plug-in and unplug effects when connected, and require a long time to be unplugged.

[0003] For example, a quick-lock high-speed transmission connector provided by authorization announcement No. CN117613598B, when it is necessary to plug the plug and the socket, the socket and the plug are connected so that the retractable lock buckle passes through the corresponding plug interface, and under the squeezing of the plug interface, the lock petal contracts inward to allow the retractable lock head to pass through the plug interface, and the lock petal is pushed outward by the insertion rod, so that the retractable lock head cannot pass through the plug interface, thereby locking the plug and the socket; when it is necessary to separate the plug and the socket, the insertion rod is pulled out of the lock petal, the limit is cancelled, and the plug and the socket can be pulled out; through the setting of structures such as the locking box, the retractable lock buckle and the guide rail locking mechanism, the plug and the socket can be quickly plugged in and out, and when unlocking, it is only necessary to slide the slider in the guide rail locking mechanism to the unlocking position first to separate the plug and the socket, and there is no need to keep pressing. Compared with existing connectors, the plug and socket are more portable and labor-saving.

[0004] It has major disadvantages: the locking rod is less efficient when inserted into the plug interface, and the insertion rod is less efficient when inserted into the lock petal; and when the insertion rod needs to be pulled out of the locking rod, the position of the slider needs to be manually adjusted to remove the restriction on the position of the locking rod. Summary of the invention

[0005] The embodiment of the present application provides a high-speed backplane connector, which solves the problems in the prior art that the locking rod is inefficient when inserted into the insertion port and the insertion rod is inefficient when inserted into the locking petal; and when the insertion rod needs to be pulled out of the locking rod, the position of the slider needs to be adjusted manually and continuously, and the restriction on the position of the locking rod is eliminated, so that the locking rod, the locking port and the expansion rod are all changed into a frustum shape. During the process of inserting the locking rod into the locking port, the initial contact area is small, and the contact area is continuously increased during the continuous insertion process, thereby improving the insertion efficiency of the locking rod into the locking port, and the expansion rod is inserted into the locking rod. During the process, the initial contact area is also small, and the contact area continues to increase during the continuous insertion process, and the efficiency of the expansion rod being inserted into the cavity of the locking rod is improved; and in the process of the locking rod being gradually away from the lock port and being pulled out, the contact area continues to shrink during the process of the expansion rod being gradually away from the lock port and being pulled out, which can improve the extraction efficiency; when the limit rod is pulled outward and the limit of the slider is cancelled, it can be quickly reset by the elastic force of the reset rope, thereby improving the separation efficiency of the plug plate and the socket; at the same time, in the process of the expansion rod being gradually inserted into the interior of the locking rod, the deformation degree of the locking rod gradually increases, thereby improving the fixing effect.

[0060] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0061] First, the lock rod, the lock mouth and the expansion rod are all changed into a truncated cone shape. When the lock rod is inserted into the lock mouth, the initial contact area is small, and the contact area is continuously increased during the continuous insertion process, thereby improving the insertion efficiency of the lock rod into the lock mouth. When the expansion rod is inserted into the lock rod, the initial contact area is also small, and the contact area is continuously increased during the continuous insertion process, thereby improving the efficiency of the expansion rod being inserted into the lock rod cavity. Moreover, when the lock rod is gradually pulled out away from the lock mouth, the contact area of ​​the expansion rod is continuously reduced during the process of being pulled out away from the lock rod, thereby improving the pulling-out efficiency. When the limit rod is pulled outward and the limit of the slider is cancelled, the elastic force of the reset rope can be used to quickly reset the position, thereby improving the separation efficiency of the plug plate and the socket. Meanwhile, when the expansion rod is gradually inserted into the lock rod, the deformation degree of the lock rod gradually increases, thereby improving the fixing effect.

[0062] Secondly, by adding a stretching rope, when the lock rod has not entered the lock mouth, the stretching rope pulls the lock rod, which can reduce the diameter of one end of the lock rod again, thereby improving the efficiency of inserting the lock rod into the lock mouth; and by pulling the stretching rope, the deformed lock rod can be quickly reset to its original state, thereby improving the efficiency of pulling the lock rod out of the lock mouth; and when the expansion rod is inserted into the lock rod, it resists the stretching rope, pulling one end of the lock rod to deform, thereby further improving the fixing effect between the plug plate and the socket;

[0063] Thirdly, by changing the end of the lock rod that extends into the protective cover into an airbag structure, the efficiency of restoring the lock rod to its original state can be improved, and the lock rod can be quickly adapted to the speed of restoring its original state when the same socket and plug-in are plugged in and out in a short period of time; and when the lock rod is pulled out of the lock port, the airbag structure at one end of the lock rod can be deformed and pulled and stored into the cavity of the lock rod, thereby improving the efficiency of pulling out; and when the airbag structure at one end of the lock rod is stored in the cavity of the lock rod, the next insertion work can be carried out without any operation, thereby further improving the insertion efficiency;

[0064] Fourthly, the insertion of the plug board is guided by the elastic rope, thereby improving the efficiency of inserting the plug board into the socket; and during the insertion process, when the user feels the resistance from the elastic rope, it will be prompted that the insertion is successful, avoiding excessive force from being applied, which may cause damage to the socket and the plug board; at the same time, the length of the deformed elastic rope is stretched, and when the limit rod is pulled out of the limit port and the limit on the lock rod is cancelled, the elastic rope will exert a force on the plug board and the protective cover to move away from the support plate, thereby pulling out the plug board, further improving the efficiency of pulling out the plug board.

[0090] Example 1: As Figures 1 - 6 shown, a high-speed backplane connector of the present application includes a connection component 100 and a limit component 200;

[0091] The connection component 100 includes a support plate 110, a socket 120, a fixing plate 130, a plug board 140, a protective cover 150, a second through port 152 and a locking port 153;

[0092] The socket 120 is fixed on one side of the support plate 110, the fixing plate 130 is annular, and the inner circle of the fixing plate 130 is fixed on the outer circle of the socket 120;

[0093] In the initial state, the plug board 140 is inserted into the socket 120, one end of the protective cover 150 has a second through port 152, and the plug board 140 is fixed in the second through port 152;

[0094] The protective cover 150 has a lock hole 153 on one side, and there are two lock holes 153, which are respectively located on both sides of the second through hole 152;

[0095] The limiting assembly 200 includes a slider 210;

[0096] The slider 210 is slidably connected to the side of the protective cover 150;

[0097] The lock 153 is in the shape of a truncated cone;

[0098] The limiting assembly 200 further includes an expansion rod 250, a locking rod 260 and a groove 1 261;

[0099] The locking rod 260 is fixed to a side of the fixing plate 130 close to the protective cover 150. The locking rod 260 is in the shape of a truncated cone that passes through along its axis. In the initial state, the locking rod 260 is slidably connected in the locking port 153.

[0100] The end of the locking rod 260 away from the fixing plate 130 has a groove 261, and there are two grooves 261, which are symmetrically arranged;

[0101] The expansion rod 250 is in the shape of a truncated cone and is fixed to a side of the slider 210 close to the locking rod 260;

[0102] In the initial state, the end of the expansion rod 250 away from the slider 210 is slidably connected in the cavity of the lock rod 260, and the expansion rod 250 is used to open one end of the lock rod 260, so that the position of the lock rod 260 in the lock port 153 is fixed and restricted;

[0103] The end of the expansion rod 250 with a smaller diameter faces the slider 210 , and the end of the locking rod 260 with a smaller diameter faces the expansion rod 250 . The minimum diameter of the expansion rod 250 is smaller than the minimum diameter of the cavity of the locking rod 260 .

[0104] When the locking rod 260 is inserted into the locking port 153, the groove 1 261 is located inside the protective cover 150;

[0105] There are two limit assemblies 200, which correspond to the two lock ports 153 one by one.

[0106] The axes of the expansion rod 250, the locking rod 260 and the locking port 153 are on the same straight line;

[0107] The connection assembly 100 further includes a limiting opening 141 and a sliding opening 151;

[0108] The two sides of the plug plate 140 are symmetrically provided with limiting openings 141, and the limiting openings 141 are located in the protective cover 150;

[0109] The protective cover 150 is symmetrically provided with sliding openings 151 on both sides;

[0110] The limiting assembly 200 further includes a slide groove 1 211, a slide groove 212, a reset rope 220, a limiting rod 230 and a spring 240;

[0111] The slider 210 is symmetrically provided with a first slide groove 211, the slider 210 is located in the sliding opening 151, and the housing of the protective cover 150 is slidably disposed in the first slide groove 211, the slider 210 is provided with a second slide groove 212, the second slide groove 212 passes through the slider 210, the limiting rod 230 is T-shaped, and the column of the limiting rod 230 is slidably disposed in the second slide groove 212 and extends into the limiting opening 141;

[0112] The sliding direction of the slider 210 is parallel to the axial direction of the expansion rod 250. The slider 210 is slidably arranged in the housing of the protective cover 150 through the slide grooves 211 on both sides, so as to facilitate the forward and backward sliding adjustment of the position of the expansion rod 250.

[0113] The spring 240 is sleeved on the column of the limiting rod 230, and one end of the spring 240 is fixed on the slider 210, and the end of the spring 240 away from the slider 210 is fixed on the crossbeam of the limiting rod 230;

[0114] The limiting rod 230 uses the elastic force of the spring 240 to extend one end of the limiting rod 230 into the limiting opening 141 to limit the position of the slider 210;

[0115] One end of the reset rope 220 is fixed to the end of the slider 210 away from the expansion rod 250, and the other end of the reset rope 220 away from the slider 210 is fixed to the inner wall of the protective cover 150 away from the second opening 152;

[0116] The reset rope 220 is used to pull the slider 210 to reset, and the reset rope 220 is made of rubber;

[0117] When the limit rod 230 column extends into the limit opening 141, the reset rope 220 is stretched;

[0118] The sliding direction of the slider 210 is parallel to the axial direction of the expansion rod 250 .

[0119] When the plug board 140 and the socket 120 need to be plugged together, the user holds the protective cover 150 with one hand to insert the plug board 140 into the socket 120, and when the user pushes the protective cover 150, two fingers push the slider 210 to slide forward together. When the slider 210 slides, the expansion rod 250 is inserted into the cavity at one end of the locking rod 260, so that one end of the locking rod 260 expands and limits the position of the locking rod 260; and when the slider 210 slides, the limiting rod 230 enters the limiting opening 141 by the elastic force of the spring 240 to limit the position of the slider 210; when the plug board 140 and the socket 120 need to be separated, the limiting rod 230 is pulled outward, and the slider 210 is reset by the elastic force of the reset rope 220, the interference of the expansion rod 250 with the locking rod 260 is cancelled, the limit is cancelled, and the protective cover 150 is pulled outward, and the socket 120 and the plug board 140 can be separated.

[0120] Compared with the prior art, the locking rod 260, the locking port 153 and the expansion rod 250 are all truncated into a cone shape. When the locking rod 260 is inserted into the locking port 153, the initial contact area is small, and the contact area is continuously increased during the continuous insertion process, thereby improving the insertion efficiency of the locking rod 260 into the locking port 153. When the expansion rod 250 is inserted into the locking rod 260, the initial contact area is also small, and the contact area is continuously increased during the continuous insertion process, thereby improving the efficiency of the expansion rod 250 being inserted into the cavity of the locking rod 260; and As the locking rod 260 is gradually pulled out away from the locking port 153, the contact area of ​​the expansion rod 250 is continuously reduced, thereby improving the pulling-out efficiency. When the limiting rod 230 is pulled outward and the limiting of the slider 210 is cancelled, the elastic force of the reset rope 220 can quickly reset the locking rod 260, thereby improving the separation efficiency of the plug plate 140 and the socket 120. At the same time, as the expansion rod 250 is gradually inserted into the locking rod 260, the deformation degree of the locking rod 260 gradually increases, thereby improving the fixing effect.

[0121] Embodiment 2: When the embodiment 1 is in use, the locking rod 260, the locking port 153 and the expansion rod 250 are in a truncated cone shape, so as to improve the plugging and unplugging efficiency. However, during use, since the locking rod 260 is resisted by the expansion rod 250 for a long time inside the protective cover 150, when the expansion rod 250 no longer resists the locking rod 260, the locking rod 260 is deformed to a large extent and the speed of returning to the original state is low; and when the locking rod 260 is inserted into the locking port 153, the locking rod 260 that has not returned to its original state will reduce the insertion efficiency. Based on this, the solution of the embodiment 1 is improved, such as Figures 7 - 10 As shown:

[0122] The connection assembly 100 further includes a through port 131;

[0123] The fixing plate 130 is provided with a through-hole 131, and the through-hole 131 passes through the fixing plate 130. There are two through-holes 131, which correspond to two locking rods 260 respectively. The two through-holes 131 are respectively located on both sides of the socket 120, and the through-hole 131 is connected with the cavity of the locking rod 260;

[0124] It also includes a power assembly 300, which includes a telescopic rod 310, a moving plate 320 and a stretching member;

[0125] The movable plate 320 is annular and is sleeved in the socket 120;

[0126] One end of the telescopic rod 310 is fixed to a side of the support plate 110 close to the fixed plate 130, and one end of the telescopic rod 310 away from the support plate 110 is fixed to the movable plate 320. The telescopic direction of the telescopic rod 310 is parallel to the axial direction of the expansion rod 250.

[0127] The telescopic rod 310 is used to adjust the position of the movable plate 320;

[0128] There are two groups of stretching members, corresponding to the two locking rods 260 respectively;

[0129] A stretching member includes two stretching ropes 330, and the two stretching ropes 330 correspond to two parts of one end of the locking rod 260 separated by two grooves 261;

[0130] The stretch cord 330 is located in the cavity of the locking rod 260;

[0131] One end of the stretch rope 330 is fixed to the end of the locking rod 260 away from the fixed plate 130, and the end of the stretch rope 330 away from the locking rod 260 passes through the through hole 131 and is fixed on the movable plate 320;

[0132] The stretch rope 330 is used to pull one end of the locking rod 260 .

[0133] When in use, when the locking rod 260 needs to be inserted into the locking port 153, the telescopic rod 310 works, and one end of the locking rod 260 is pulled by the stretch rope 330 to make the one ends of the locking rod 260 close to each other. When the locking rod 260 is inserted into the protective cover 150, the telescopic rod 310 is reset, and when the expansion rod 250 is inserted into the locking rod 260, it can resist the stretch rope 330 and pull one end of the locking rod 260 to deform; when the locking rod 260 needs to be pulled out of the locking port 153, the expansion rod 250 is pulled out of the locking rod 260, and when the limit on the locking rod 260 is cancelled, the telescopic rod 310 pulls the stretch rope 330, so that the locking rod 260 that is pressed and deformed by the expansion rod 250 is quickly reset, restored to its original state, and extended out of the locking port 153.

[0134] By adding the stretching rope 330, when the locking rod 260 has not entered the locking port 153, the stretching rope 330 pulls the locking rod 260, which can reduce the diameter of one end of the locking rod 260 again, thereby improving the efficiency of inserting the locking rod 260 into the locking port 153; and by pulling the stretching rope 330, the deformed locking rod 260 can be quickly reset to its original state, thereby improving the efficiency of pulling the locking rod 260 out of the locking port 153; and when the expansion rod 250 is inserted into the locking rod 260, it resists the stretching rope 330, pulling one end of the locking rod 260 to deform, which can further improve the fixing effect between the plug plate 140 and the socket 120.

[0135] Embodiment 3: When the embodiment 2 is in use, the locking rod 260 is quickly restored to its original state by pulling one end of the locking rod 260 by the stretching rope 330. However, when the same socket 120 and the plugboard 140 are plugged in and out in a short period of time, the restoration speed of the locking rod 260 by pulling the locking rod 260 by the stretching rope 330 is slow. Based on this, the solution of the embodiment 2 is improved, such as Figures 11 - 15 As shown:

[0136] The portion of the locking rod 260 located in the cavity of the protective cover 150 is an airbag structure;

[0137] The power assembly 300 further includes a support rod 340;

[0138] The number of the support rods 340 is consistent with the number of the stretching ropes 330, and they correspond one to one. The support rods 340 are cylindrical and pass through along their axes. The stretching ropes 330 are fixed in the cavities of the support rods 340. The length of the stretching ropes 330 is consistent with the length of the support rods 340. The two ends of the support rods 340 are respectively fixed to one end of the locking rod 260 away from the fixed plate 130 and the movable plate 320;

[0139] The support rod 340 is made of polyurethane and has a certain hardness and elasticity;

[0140] The connection assembly 100 further includes an air intake pipe 132;

[0141] The fixing plate 130 has an air intake duct 132 therein;

[0142] The limiting assembly 200 also includes an air intake pipe 262 and an air pump 270;

[0143] The locking rod 260 is provided with a second air intake duct 262, and the second air intake duct 262 is connected to the first air intake duct 132 and the interior of the airbag structure at one end of the locking rod 260;

[0144] The air pump 270 is fixed on the fixing plate 130, and the output end of the air pump 270 is connected to the air inlet pipe 132;

[0145] The air pump 270 is used to supply or exhaust air to the airbag structure at one end of the locking rod 260. When the air pump 270 is working, the gas enters the airbag structure at one end of the locking rod 260 through the air intake pipe 1 132 and the air intake pipe 2 262, or the gas is discharged from the airbag structure at one end of the locking rod 260 through the air intake pipe 1 132 and the air intake pipe 2 262.

[0146] When in use, when the locking rod 260 needs to be inserted into the lock port 153, the telescopic rod 310 works, and one end of the locking rod 260 is pulled by the stretch rope 330, so that the one end of the locking rod 260 is close to each other, and the rubber material at one end of the locking rod 260 is stretched into the interior of the locking rod 260 cavity; when the locking rod 260 is inserted into the protective cover 150, the telescopic rod 310 is reset, and the locking rod 260 is restored to its original state by the resistance of the stainless steel stretch rope 330, so that the part pulled into the locking rod 260 is stretched out of the locking rod 260, so that the expansion rod 250 is inserted into the cavity of the locking rod 260, and at the same time as the expansion rod 250 is inserted into the locking rod 260, one end of the locking rod 260 is inflated by the air pump 270, and the expansion rod inserted into the cavity of the locking rod 260 is expanded. The rod 250 can make one end of the locking rod 260 expand toward the outer circle; when the locking rod 260 needs to be pulled out from the locking port 153, the expansion rod 250 is pulled out from the inside of the locking rod 260, and the air pump 270 works to quickly deflate one end of the locking rod 260. When the expansion rod 250 moves to a point where it is no longer in contact with the locking rod 260, the telescopic rod 310 pulls the stretch rope 330 to stretch the rubber material at one end of the locking rod 260 into the cavity of the locking rod 260, restores its original shape, and extends out from the locking port 153; the support rod 340 made of polyurethane material has a certain hardness and elasticity. Its own hardness can push the airbag structure contained in the cavity of the locking rod 260 out of the cavity of the locking rod 260, and its own elasticity can adapt to the deformation of the airbag structure at one end of the locking rod 260 after expansion.

[0147] By converting the end of the locking rod 260 that extends into the protective cover 150 into an airbag structure, the efficiency of restoring the locking rod 260 to its original state can be improved, and the speed at which the locking rod 260 restores to its original state can be quickly adapted to plugging and unplugging the same socket 120 and the plug board 140 in a short period of time; and when the locking rod 260 is pulled out of the locking port 153, the airbag structure at one end of the locking rod 260 can be deformed and pulled and accommodated into the cavity of the locking rod 260, thereby improving the extraction efficiency; and when the airbag structure at one end of the locking rod 260 is accommodated in the cavity of the locking rod 260, the next insertion work can be carried out without any operation, thereby further improving the insertion efficiency.

[0148] Embodiment 4: When the embodiment 3 is in use, the lock rod 260 of the airbag structure is conveniently stored, thereby improving the efficiency of plugging and unplugging. However, when in use, the device can be improved to further improve the plugging and unplugging efficiency between the socket 120 and the plugboard 140. Based on this, the solution of embodiment 3 is improved, such as Figures 16 - 18 As shown:

[0149] Also included is an elastic cord 400;

[0150] The two ends of the elastic rope 400 are fixed to the sides of the two locking rods 260 that are close to each other;

[0151] The position limiting assembly 200 further includes a storage slot 263;

[0152] The two locking rods 260 have a storage groove 263 on one side close to each other. The storage groove 263 is located on the side of the airbag material of the locking rod 260. The length direction of the storage groove 263 is in the same straight line as the generatrix of the locking rod 260. Both ends of the elastic rope 400 are fixed in the storage groove 263.

[0153] When the locking rod 260 is inserted into the locking port 153, a portion of the storage slot 263 is located in the locking port 153, and the storage slot 263 is not provided on the airbag structure at one end of the locking rod 260;

[0154] When the locking rod 260 is inserted into the locking port 153 , the elastic cord 400 is resisted by the protective cover 150 and stored in the storage slot 263 ;

[0155] When the plug board 140 is inserted into the socket 120 , the elastic rope 400 is closely attached to one side of the plug board 140 .

[0156] When in use, when the plug board 140 is inserted into the socket 120, the plug board 140 is located on one side of the elastic rope 400, and the insertion of the plug board 140 is guided by the elastic rope 400. During the process of inserting into the socket 120, the elastic rope 400 will be deformed to store the elastic rope 400 in the storage groove 263; when the plug board 140 is pulled out, due to the length of the elastic rope 400 being stretched, the elastic rope 400 will apply a force to the plug board 140 and the protective cover 150 away from the support plate 110, thereby popping out the plug board 140.

[0157] The insertion of the plug board 140 is guided by the elastic rope 400, thereby improving the efficiency of inserting the plug board 140 into the socket 120; and during the insertion process, when the user feels the resistance from the elastic rope 400, it will be prompted that the insertion is successful, avoiding excessive force from being applied, which may cause damage to the socket 120 and the plug board 140; at the same time, the length of the deformed elastic rope 400 is stretched, and when the limit rod 230 is pulled out of the limit port 141 and the limit on the locking rod 260 is cancelled, the elastic rope 400 will apply a force to the plug board 140 and the protective cover 150 away from the support plate 110, thereby pulling out the plug board 140, further improving the efficiency of pulling out the plug board 140.

[0158] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
