Description

Technical Field

[0001] This application relates to the technical field of connectors, and particularly to a plugging and unplugging structure. Background Art

[0002] An electrical connector generally includes a plug and a socket. The electrical connector realizes electrical connection and signal transmission between devices or systems through the mating of the plug and the socket, and the connection stability directly affects the reliability of the entire system. To ensure the tight fit between the plug and the socket without loosening, a threaded locking method is usually used to lock the plug and the socket. Reference can be made to a threaded locking connector with the publication number CN214957595U. This method requires screwing in and out of the thread every time for locking and disassembling, and the operation process is cumbersome, which results in a long time-consuming plugging and unplugging process. The connector cannot be quickly and effectively plugged and unplugged, and is not suitable for occasions with multiple disassembly and assembly operations. At the same time, with the development of connectors, most current connectors have more cores. As the number of cores of the connector increases, the plugging and unplugging force of the connector also increases. When the number of cores of the connector reaches a certain amount, it is very difficult to separate the socket from the plug only by the strength of the human hand, and the plugging and unplugging process is time-consuming and laborious.

[0003] Therefore, how to improve the convenience of plugging and unplugging the connector to save the plugging and unplugging time and reduce the force of the plugging and unplugging operation has become an urgent problem to be solved. Summary of the Invention

[0004] In view of this, this application proposes a plugging and unplugging structure, which is suitable for improving the convenience of plugging and unplugging the connector to save the plugging and unplugging time.

[0005] According to one aspect of this application, a plugging and unplugging structure is provided, which is characterized in that it includes: a fixing plate, a pressing rod, a connecting piece, a ejector rod, a locking sleeve, and a connecting sleeve;

[0006] The fixing plate is fixedly connected to one end of the pressing rod, the pressing rod is connected to one end of the ejector rod through a connecting piece, the connecting sleeve is provided with a cavity with one end open, and the other end of the ejector rod can extend into the cavity of the connecting sleeve;

[0007] The locking sleeve is sleeved outside the ejector rod;

[0008] One end of the locking sleeve has a first clamping portion, and the end of the locking sleeve provided with the first clamping portion is made of an elastically deformable material. The opening of the connecting sleeve can cause the locking sleeve to elastically deform by squeezing the first clamping portion;

[0009] The fixing plate is suitable for being fixedly connected to any one of the plug housing or the socket housing, and the connecting sleeve is suitable for being fixedly connected to the other one of the socket housing or the plug housing.

[0010] In a possible implementation manner, the opening of the connecting sleeve is a circular hole-shaped structure;

[0011] The diameter of the opening is smaller than the diameter of the cavity of the connecting sleeve.

[0012] In a possible implementation, the first clamping portion is sleeved on the outer side wall of the connecting sleeve.

[0013] The diameter of the first clamping portion is larger than the diameter of the opening.

[0014] In a possible implementation, a second clamping portion is provided at one end of the ejector rod that extends into the connecting sleeve.

[0015] The first clamping portion is provided with a limiting groove, the limiting groove is matched with the second clamping portion, and the second clamping portion can be embedded into the limiting groove.

[0016] In a possible implementation, one end of the connecting piece passes through the locking sleeve and is connected to the ejector rod.

[0017] In a possible implementation, the ejector rod includes: a first cylindrical rod and a second cylindrical rod that are fixedly connected.

[0018] One end of the first cylindrical rod is connected to the connecting piece; the other end of the first cylindrical rod is connected to the second cylindrical rod.

[0019] The diameter of the second cylindrical rod is smaller than the diameter of the first cylindrical rod.

[0020] In a possible implementation, the pressure rod is provided with a first connection hole and a second connection hole.

[0021] The first connection hole and the second connection hole are arranged adjacent to each other.

[0022] In a possible implementation, the pressure rod is connected to the fixing plate through the first connection hole.

[0023] The connecting portion is connected to the connecting piece through the second connection hole.

[0024] Advantageous effects: This application can achieve the connection and fixation of the socket and the plug without the need for thread fixation, and can quickly separate the two. The plugging and unplugging process takes a short time, and can be quickly and effectively plugged and unplugged, especially suitable for occasions where the connector needs to be disassembled and assembled multiple times. At the same time, with the development of connectors, most current connectors have more cores. As the number of cores of the connector increases, the plugging and unplugging force of the connector also increases. When the number of cores of the connector reaches a certain amount, it is very difficult to separate the socket and the plug only by the strength of the human hand, and the plugging and unplugging process is time-consuming and laborious. This application uses the lever principle to achieve the insertion and separation of the socket and the plug, which is not only easy to operate, but also greatly reduces the force required for insertion and separation, and makes it easier to plug and unplug the connector.

[0040] Figure 1 Showing a cross-sectional view before connection of a plug-and-play structure according to an embodiment of this application; Figure 2 Showing a cross-sectional view during connection of a plug-and-play structure according to an embodiment of this application; Figure 3 Showing a schematic diagram of the pre-tightened state of a plug-and-play structure according to an embodiment of this application; Figure 4 Showing a schematic diagram of the locking process state of a plug-and-play structure according to an embodiment of this application; Figure 5 Showing a schematic diagram of the locked state of a plug-and-play structure according to an embodiment of this application; Figure 6 Showing a front view of the pressure bar of a plug-and-play structure according to an embodiment of this application; Figure 7 Showing a front view of the connecting member of a plug-and-play structure according to an embodiment of this application; Figure 8 Showing a partial view of a plug-and-play structure according to an embodiment of this application. As Figure 1As shown in the figure, the plug-and-play structure includes: a fixing plate 100, a pressing rod 200, a connecting member 300, a ejector rod 400, a locking sleeve 500, and a connecting sleeve 600; one end of the fixing plate 100 is fixedly connected to one end of the pressing rod 200, the pressing rod 200 is connected to one end of the ejector rod 400 through the connecting member 300, the connecting sleeve 600 is provided with a cavity with one end open, the other end of the ejector rod 400 can extend into the interior of the cavity of the connecting sleeve, and the ejector rod 400 is detachably connected to the connecting sleeve 600; the locking sleeve 500 is sleeved outside the ejector rod 400; one end of the locking sleeve 500 has a first clamping portion 510, and the end of the locking sleeve 500 provided with the first clamping portion 510 is made of an elastically deformable material, and the opening of the connecting sleeve 600 can cause the locking sleeve 600 to elastically deform in the radial direction by squeezing the first clamping portion 510; the fixing plate 100 is suitable for being fixedly connected to any one of the plug housing 700 or the socket housing 800, and the connecting sleeve 600 is suitable for being fixedly connected to the other of the socket housing 800 or the plug housing 700.

[0041] Here, it should be noted that the socket housing 800 is adapted to the plug housing 700. Further, the fixing plate 100 is fixedly connected to the plug housing 700, and the connecting sleeve 600 is fixedly connected to the socket housing 800, so that the socket housing 800 is in contact with the plug housing 700. The fixing plate 100 is suitable for fixing the pressure rod 200, and the pressure rod 200 can rotate relative to the connection point of the fixing plate 100. The pressure rod 200 is connected to the connecting member 300 and is suitable for driving the connecting member 300 to move up and down when rotating. The connecting member 300 is connected to the ejector rod 400 and is suitable for driving the ejector rod 400 to move up and down when the connecting member 300 moves. The other end of the ejector rod 400 can be inserted into the cavity of the connecting sleeve 600 and will not be separated from the cavity of the connecting sleeve 600 under the action of the locking sleeve 500. When the ejector rod 400 moves, it drives the connecting sleeve 600 to move up and down, and the connecting sleeve 600 drives the fixed socket housing 800 to move up and down, so as to realize the connection and separation between the socket and the plug. When the socket and the plug are connected, the pressure rod 200 remains in a locked state, and the push rod 400 remains in a pressed state on the connecting sleeve 600, so that the connecting sleeve 600 remains stationary and continuously fixed, thereby ensuring the connection stability between the socket and the plug and avoiding the separation of the two. If the socket and the plug need to be disconnected, the pressure rod 200 is rotated, and the pressure rod 200 drives the push rod 400 to loosen the connecting sleeve 600. Finally, the push rod 400 applies opposite pressure to the connecting sleeve 600, and the push rod 400 pushes open the connecting sleeve 600, thereby realizing the separation of the socket shell 800 and the plug shell 700. The overall structure of the present application is simple and the operation process is simple. The connection and fixation of the socket and the plug can be realized without threaded fixing, and the separation of the two can be realized quickly. The plugging and unplugging process is time-consuming and can be plugged and unplugged quickly and effectively, which is particularly suitable for occasions where the connector is disassembled and assembled multiple times. At the same time, with the development of connectors, most connectors currently have more cores. As the number of connector cores increases, the plugging and unplugging force of the connector is also increasing. When the number of connector cores reaches a certain amount, it is difficult to separate the socket and the plug by hand alone. This plugging and unplugging process is time-consuming and laborious. The present application uses the lever principle to achieve the plugging and separation of the socket and the plug, which is not only easy to operate, but also greatly reduces the force required for plugging and separation, making it easier to plug and unplug the connector.

[0042] In a possible implementation, the connecting sleeve 600 is provided with an internal cavity with an opening 610 at one end; it should be noted here that the connecting sleeve 600 is a cylindrical structure as a whole, hollow inside, and a circular opening 610 is provided on a side corresponding to the connecting rod to enable the insertion of the ejector rod 400 and the locking sleeve 500. The diameter of the opening 610 is smaller than the diameter of the cavity of the connecting sleeve 600.

[0043] One end of the locking sleeve 500 that protrudes into the opening 610 has a first locking portion 510 . The first locking portion 510 is sleeved on the outer wall of the connecting sleeve 600 , and the first locking portion 510 matches the inner cavity of the connecting sleeve 600 .

[0044] The diameter of the first clamping position portion 510 is greater than the diameter of the opening 610. Here, it should be noted that when the socket is connected to the plug, the locking sleeve 500 and the ejector rod 400 are inserted into the connecting sleeve 600 together. Since the locking sleeve 500 is made of an elastically deformable material, the opening 610 of the connecting sleeve 600 can elastically deform the locking sleeve 600 in the radial direction by squeezing the first clamping position portion 510, so that the locking sleeve 500 and the ejector rod 400 can be smoothly inserted into the locking sleeve 500; the diameter of the cavity of the connecting sleeve 600 is greater than the diameter of the opening 610, and at the same time, the diameter of the cavity of the connecting sleeve 600 is greater than the diameter of the first clamping position portion 510 in the relaxed state of the locking sleeve 500. The first clamping position portion 510 is not squeezed, and the locking sleeve 500 relaxes and resets. At this time, the first clamping position portion 510 is suitable for limiting the locking sleeve 500. When the ejector rod 400 moves upward, the locking sleeve 500 is sleeved outside the ejector rod 400 and will also move upward with the ejector rod 400. Since the diameter of the first clamping position portion 510 is greater than the diameter of the opening 610, it is ensured that the locking sleeve 500 will not continue to move upward, preventing the locking sleeve 500 from slipping out of the connecting sleeve 600.

[0045] In a possible implementation manner, the main body of the locking sleeve 500 is a circular tube structure. The locking sleeve 500 is sleeved outside the ejector rod 400, but there is no fixed connection between the ejector rod 400 and the locking sleeve 500; the ejector rod 400 can move up and down inside the locking sleeve 500. One end of the locking sleeve 500 is provided with a plurality of elastic pieces, and the plurality of elastic pieces are arranged annularly along the tubular structure. There is a preset gap between each elastic piece. The first clamping position portion 510 is arranged on the outer side of each elastic piece. When the first clamping position portion 510 is squeezed, each elastic piece contracts inward. When the first clamping position portion 510 is not compressed, each elastic piece resets outward. Further, the material of the locking sleeve 500 is metal.

[0046] In a possible implementation manner, one end of the ejector rod 400 extending into the connecting sleeve 600 is provided with a second clamping position portion 410, and the second clamping position portion 410 contacts the first clamping position portion 510. As Figure 8 And Figure 4As shown, the main body of the second clamping part 410 is also an annular structure, and the cross-section is a trapezoidal structure, which is sleeved on one end of the top rod 400. A limiting groove is provided at the bottom of the first clamping part 510, and the limiting groove matches the second clamping part 410. The second clamping part 410 can be embedded in the limiting groove at the bottom of the first clamping part 510. The top rod 400 is inside the locking sleeve 500. When the top rod 400 moves upward, the second clamping part 410 will contact the first clamping part 510, and be embedded in the first clamping part 510, and contact each other. Since the locking sleeve 500 is an elastic deformation material, it has a large elasticity and can be deformed. When the push rod 400 moves upward, the locking sleeve 500 moves upward accordingly. To prevent the first locking portion 510 from being compressed by the opening 610, causing the locking sleeve 500 to deform and the locking sleeve 500 and the push rod 400 to slide out of the connecting sleeve 600, the second locking portion 410 can not only limit the simultaneous movement of the push rod 400 and the locking sleeve 500, but also effectively prevent the first locking portion 510 from being compressed inwardly and deformed, thereby effectively ensuring that the push rod 400 will not separate from the connecting sleeve 600 during the connection between the plug and the socket.

[0047] In a possible implementation, the diameter of the end of the push rod 400 that penetrates into the connecting sleeve 600 is smaller than the diameter of the end of the push rod 400 that connects to the connecting piece 300. Here, it should be noted that the diameter of the end of the push rod 400 provided with the second clamping portion 410 is smaller, which is suitable for the locking sleeve 500 to deform inwards, so as to facilitate the locking sleeve 500 and the push rod 400 to pass through the opening 610 of the connecting sleeve 600. Further, the push rod 400 includes: a first cylindrical rod and a second cylindrical rod that are fixedly connected; one end of the first cylindrical rod is connected to the connecting piece 300; the other end of the first cylindrical rod is connected to the second cylindrical rod; the diameter of the second cylindrical rod is smaller than the diameter of the first cylindrical rod.

[0048] In a possible implementation, a connection hole 420 is provided at one end of the first cylindrical rod connected to the connecting member 300 ; the top rod 400 is connected to the connecting member 300 via the connection hole 420 and the connecting screw.

[0049] In a possible implementation, one end of the connector 300 passes through the locking sleeve 500 and is connected to the push rod 400. Here, it should be noted that an oblong through hole is provided on one side of the locking sleeve 500, and the connector 300 passes through the oblong through hole and is connected to the push rod 400 inside the locking sleeve 500.

[0050] In one possible implementation, Figure 6As shown, the pressure rod 200 includes a hand-held portion 220 and a connecting portion 210; the main body of the connecting portion 210 is a long strip structure, and further, the main body of the connecting portion 210 can be a rectangular parallelepiped structure or a trapezoidal structure. The main body of the hand-held portion 220 is a rod-shaped structure, and the length of the rod-shaped structure is L1; one end of the hand-held portion 220 and the fixing plate 100 are respectively arranged on two opposite sides R of the connecting portion 210. Here, it should be noted that one end of the hand-held portion 220 is completely in contact with one side of the body length of the connecting portion 210, and by moving the hand-held portion 220, the hand-held portion 220 can be rotated counterclockwise and clockwise to drive the connecting portion 210 to rotate.

[0051] In a possible implementation, the connection portion 210 is provided with a first connection hole 211 and a second connection hole 212; the first connection hole 211 and the second connection hole 212 are arranged adjacent to each other along the length direction of the connection portion 210. Here, it should be noted that the main body of the first connection hole 211 is a circular hole structure, and the main body of the second connection hole 212 is also called a circular hole structure. The first connection hole 211 and the second connection hole 212 are arranged adjacent to each other, and the interval distance between the first connection hole 211 and the second connection hole 212 is L2.

[0052] In a possible implementation, the main body of the connecting member 300 is a C-shaped structure; the open end of the C-shaped structure faces the fixing plate 100. Figure 7 As shown, the connecting member 300 is a C-shaped sheet structure, and the two sides of the open end of the C-shaped structure are respectively connected to the pressure rod 200 and the push rod 400.

[0053] In a possible implementation, the connecting portion 210 is connected to the fixing plate 100 through the first connecting hole 211; the connecting portion 210 is connected to one end of the C-shaped structure of the connecting member 300 through the second connecting hole 212. Here, it should be noted that the main body of the fixing plate 100 is a rectangular plate-like structure, and a fixing portion is provided on one side of the fixing plate 100 connected to the pressure rod 200, and the pressure rod 200 is connected to the fixing plate 100 through the fixing portion. Further, the main body of the fixing portion is a rectangular plate-like structure, and a circular through hole is provided in the fixing portion. The first connecting hole 211 is correspondingly arranged with the circular through hole and connected by bolts. There is a preset gap between the connecting portion 210 and the fixing plate 100 so that the connecting portion 210 performs a circular rotation motion with the first connecting hole 211 as the center.

[0054] In one possible implementation, Figure 7 As described, two circular through holes 310 and 320 are respectively provided on both sides of the open end of the C-shaped structure of the connecting piece 300, the second connecting hole 212 corresponds to the circular through hole 310 and is connected by bolts; the other circular through hole 320 corresponds to the connecting hole 420 of the top rod 400 and is connected by bolts.

[0055] In a possible implementation, the fixing plate 100 is connected to the plug housing 700. The fixing part and the plug housing 700 are respectively arranged on opposite side surfaces of the fixing plate 100. On one side of the plug housing 700 opposite to the locking sleeve 500, there is a second fixing part 710. The main body of the second fixing part 710 is in a cylindrical structure, and there is a through hole in the middle. The second fixing part 710 is sleeved on the middle part of the locking sleeve 500.

[0056] In a possible implementation, the connecting sleeve 600 is connected to the socket housing 800. Further, the connecting sleeve 600 is connected to the socket housing 800 through a third fixing part 810. The third fixing part 810 is arranged on the outer side wall of the socket housing 800. The main body of the third fixing part 810 is in a cylindrical structure, and there is a through hole in the middle. The third fixing part 810 is arranged at the bottom of the connecting sleeve 600. Further, a connecting shaft 620 is arranged at the bottom of the connecting sleeve 600. The connecting sleeve 600 and the connecting shaft 620 are integrally fixed. The through hole in the middle of the third fixing part 810 matches the connecting shaft 620. The third fixing part 810 is sleeved on the outer side wall of the connecting shaft 620 through a threaded structure to realize the connection between the connecting sleeve 600 and the socket housing 800.

[0057] This application realizes the insertion and separation of the socket housing 800 and the plug housing 700 through the lever principle, and has the advantages of being easy to operate, labor-saving, and more easily realizing the plugging and unplugging of the connector. Further, it is explained by a formula.

[0058] According to the lever balance condition:

[0059] F1×L1 = F2×L2……………………………………(1)

[0060] In the formula, F1——driving force

[0061] L1——length of the driving arm

[0062] F2——resistance force

[0063] L2——length of the resistance arm

[0064] In the present invention, the relationship between L1 and L2 is as follows Figure 4 as shown. Among them, the distance from the bottom end of the handheld part 220 to the first connection hole 211 is the driving arm, and its length is L1; the interval distance between the first connection hole 211 and the second connection hole 212 is the resistance arm, and its length is L2. According to the formula, the ratio of the length L1 of the driving arm to the length L2 of the resistance arm is equal to the inverse ratio of the driving force to the resistance force. The longer the length L1 of the driving arm, the shorter the length L2 of the resistance arm, and the more force can be saved. F1 = F2×L2 / L1; in this application, the length of the driving arm L1 is greater than the length of the resistance arm L2. According to the formula, the required driving force F1 is less than the resistance force F2, and compared with directly plugging and unplugging by hand, force can be saved.

[0065] The overall operation process of this application will be described: Figure 1 The sectional view before the connection of a plug - and - unplug structure according to an embodiment of this application is shown, in an initial unconnected state. The locking sleeve 500 and the ejector rod 400 are not inside the cavity of the connection sleeve 600. Before insertion, the pressure rod 200 should be turned to the state as shown in Figure 1 the figure, align the socket housing 800 with the plug housing 700, and align the locking sleeve 500 and the connection sleeve 600 for insertion; Figure 2 The sectional view when the plug - and - unplug structure according to an embodiment of this application is being connected is shown; the locking sleeve 500 is made of an elastic material. When the socket housing 800 and the plug housing 700 are pushed, when the locking sleeve 500 and the ejector rod 400 penetrate into the connection sleeve 600, the locking sleeve 500 will deform when it is squeezed by the opening 610 of the connection sleeve 600, as shown in Figure 2 the figure; continue to push the socket housing 800 and the plug housing 700, the ejector rod 400 abuts against the bottom of the connection sleeve 600, and the locking sleeve 500 returns to the state before being squeezed, as shown in Figure 3 the figure, which shows a schematic diagram of the pre - tightening state of a plug - and - unplug structure according to an embodiment of this application; turn the pressure rod 200 clockwise, drive the ejector rod 400 to move upward through the connecting member 300 until the second engaging portion 410 of the ejector rod 400 catches the first engaging portion 510 of the locking sleeve 500, preventing the locking sleeve 500 from deforming, and the locking sleeve 500 is stuck inside the cavity of the connection sleeve 600, as shown in Figure 4 the figure, Figure 4 which shows a schematic diagram of the locking process state of a plug - and - unplug structure according to an embodiment of this application; continue to turn the pressure rod 200 clockwise, the ejector rod 400 continues to move upward, the ejector rod 400 and the locking sleeve 500 jointly pull the connection sleeve 600 to move upward, driving the socket housing 800 and the plug housing 700 to move in the insertion direction. When the pressure rod 200 cannot be turned anymore, the socket and the plug are inserted in place and locked, as shown in Figure 5 the figure; Figure 5 which shows a schematic diagram of the locked state of a plug - and - unplug structure according to an embodiment of this application, realizing the insertion of the connector. On the contrary, when the connector needs to be separated, press the pressure rod 200 counterclockwise downward, the connecting member 300 moves downward, and the ejector rod 400 follows to move downward, so that the second engaging portion 410 of the ejector rod 400 releases the first engaging portion 510 of the locking sleeve 500. Finally, the ejector rod 400 abuts against the inner side wall of the connection sleeve 600; continue to rotate the pressure rod 200 counterclockwise, and push the socket housing 800 and the plug housing 700 apart through the ejector rod 400 to realize the separation of the connector.
