Description

Technical Field

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

[0002] A high-speed backplane connector is a connection component designed for high-speed data transmission, and is widely used in fields such as communication, computers, and data centers. It can support high-frequency signal transmission, ensure low latency and high bandwidth, and meet the strict requirements of modern devices for data transmission rates. Such connectors usually adopt advanced designs and materials to reduce signal loss and crosstalk and improve overall performance. The reliability and stability of high-speed backplane connectors make them key components in high-performance systems, supporting various applications such as fiber optics, Ethernet, and high-speed serial communication.

[0003] In the prior art, due to the large number of plug-in ports on the backplane connector, the static friction force suffered by the backplane connector when being pulled out is large, and it is difficult for the user to complete the pulling-out work. And because it is difficult to pull out, the user usually shakes the connector when pulling out to assist in pulling out the connector. At the same time, due to the large number of plug-in ports, this pulling-out method is likely to loosen the metal contacts on the connector, and in severe cases, it will cause damage to the connector.

[0004] Therefore, a high-speed backplane connector is proposed to solve the above problem of inconvenient pulling out. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-speed backplane connector to solve the problem of inconvenient pulling out.

[0006] To achieve this purpose, the present invention adopts the following technical solutions: A high-speed backplane connector includes a connector body and a socket that are inserted into each other along a first direction. A jacking mechanism is provided on the connector body, and the jacking mechanism is used to push the connector body away from the plug. The jacking mechanism includes a housing, a top block, a pushing part, and a linkage unit. The housing is disposed on the connector body corresponding to the side surface of the connector body. The top block moves in the housing along the first direction towards the socket. The pushing part is disposed in the housing corresponding to the top block. The linkage unit is disposed on the housing and is connected to the pushing part. The linkage unit is used to switch the pushing part from a first state to a second state. When the pushing part is switched to the second state, the top block moves in the housing towards the socket. When the top block moves to a first position in the housing, the top block drives the connector body to separate from the plug.

[0007] Preferably, an installation groove is formed on the connector body. The housing is disposed in the installation groove along the first direction, and the number of housings located on one of the side surfaces of the connector body is at least one.

[0008] Preferably, a through hole for the top block to penetrate is formed on one side of the housing facing the socket, and the top block is moved out of the housing through the through hole. A restricting member is provided on the top block, and a restricting groove corresponding to the restricting member is formed on the inner side wall of the housing. The restricting member is slidably connected to the restricting groove, and the restricting member and the restricting groove cooperate to limit the moving distance of the top block. When the top block is in the first position, the restricting member abuts against the inner side wall of the restricting groove close to the socket.

[0009] Preferably, the pushing portion includes a first spring and a push plate connected in sequence. The first spring is connected to the inner side wall of the housing, and the push plate is slidably connected in the housing. The first spring, the push plate, and the top block are arranged in sequence along the first direction. A clamping structure for clamping with the housing is provided on the push plate, and the clamping structure is connected to the linkage unit. When the pushing portion is in the first state, the first spring and the push plate are both in a contracted state, and the clamping structure is clamped with the housing; when the pushing portion is in the second state, the first spring and the push plate are both in a released state, the clamping structure is separated from the housing, and the push plate also abuts against the top block and the top block is in the first position.

[0010] Preferably, the clamping structure includes a clamping block and a second spring connected in sequence. A groove is formed on the push plate, the clamping block is connected to the groove through the second spring, and the clamping block is telescopically movable in the groove towards the linkage unit along the second direction. A limiting hole corresponding to the clamping block is formed on the housing. When the pushing portion is in the first state, the clamping block is inserted into the limiting hole, and the clamping block penetrates through the limiting hole and is connected to the linkage unit; when the pushing portion is in the second state, the clamping block is separated from the linkage unit.

[0011] Preferably, the linkage unit includes a mounting frame and a plurality of balls. The mounting frame is arranged on the housing corresponding to the clamping block and is connected to the connector body. The balls are rotatably connected in the mounting frame. When the pushing portion is in the first state, the clamping block penetrates and extends into the mounting frame and abuts against the balls. A plurality of balls located between adjacent two clamping blocks abut against each other in sequence. When any ball that does not abut against the clamping block moves a pushing distance in the mounting frame, the clamping block moves out of the mounting frame, and the pushing portion can be switched from the first state to the second state.

[0012] Preferably, a pushing block is arranged on the mounting frame corresponding to the clamping block, and a through hole for the pushing block to penetrate is formed on the mounting frame. The pushing block moves towards the clamping block in the second direction. The pushing block is used to push the clamping block out of the mounting frame. The width and the pushing distance of the pushing block are equal to the width of a plurality of clamping blocks. An inclined surface corresponding to the balls is formed on one side of the pushing block close to the clamping block. After the pushing block moves towards the clamping block, the balls are pushed to move through the inclined surface.

[0013] Preferably, there are two support plates corresponding to the push block on the mounting bracket. The push block is slidably connected between the two support plates and is clamped with the support plates. The push block is located outside the mounting bracket under normal conditions.

[0014] Preferably, the cross-section of the mounting bracket is in the shape of a double-square frame. The length and width of the inner cavity of the mounting bracket are both equal to the diameter of the ball. The side of the connector body in the first direction is an arc adapted to the outer circumference of the ball.

[0015] Preferably, a guiding groove is provided on the side of the socket facing the connector body corresponding to the top block. The length and width of the top block are respectively equal to the length and width of the inner cavity of the guiding groove. When the connector body is connected to the socket, the top block is inserted into the guiding groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. For a high-speed backplane connector of the present invention, when the connector body is separated from the socket through the ejection mechanism, it is not necessary for the user to manually pull out the connector body from the socket. The pulling-out process is convenient and fast, avoiding damage to the metal contact caused by the user's manual pulling and shaking of the connector, protecting the metal contact. Moreover, with a simple structure of the ejection mechanism and the cooperation of structures such as the top block, the pushing part, and the linkage unit in the ejection mechanism, the process of pulling out the connector body and the socket can be simplified. Only the movement of the top block is required, improving the pulling-out efficiency.

[0017] 2. For a high-speed backplane connector of the present invention, through the strict matching of the dimensions of the guiding groove on the socket and the top block, precise alignment is achieved by inserting the top block into the guiding groove during connection, reducing the risk of plugging deviation. During separation, the reaction force generated by the movement of the top block is evenly transmitted to the socket through the inner wall of the guiding groove, avoiding damage to the metal contact caused by local stress. In addition, after connection, the top block retracts into the shell body and automatically switches to the first state through the pushing part, simplifying the reset operation.

[0018] 3. For a high-speed backplane connector of the present invention, by adopting a pushing part combined with a first spring and a push plate, elastic potential energy can be stored when the first spring is compressed, and when released, it is converted into a linear thrust through the push plate and evenly transmitted to the top block. The planar structure of the push plate avoids local stress concentration, ensuring the stable movement of the top block along the first direction. In addition, with the cooperation of the second spring and the block, the automatic reset locking of the push plate is realized through the inclined inner wall of the limiting hole, making the separation action controllable and stable, capable of precisely overcoming the static friction between the connector body and the socket, and preventing mis-triggering at the same time, improving the operation safety.

[0019] 4. A high-speed backplane connector of the present invention transmits thrust through a ball chain in a linkage unit, causing all the latch blocks to move out of the mounting bracket simultaneously, releasing the push plate to push the top block, enabling the four top blocks to move synchronously. At the same time, when the top block moves, the cooperation between the limiting member and the limiting groove further ensures the accurate movement trajectory of the top block, so that when the connector body is separated from the socket, the force is evenly distributed, avoiding the loosening or damage of the metal contacts caused by shaking or uneven force during traditional plugging and unplugging, and significantly improving the durability and stability of the connector.

[0024] In order to make the invention purpose, features, and advantages of the present invention more obvious and understandable, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the following described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present at the same time.

[0026] Embodiment 1: Please refer to Figures 1-10 , a high-speed backplane connector in this embodiment includes a connector body 1 and a socket 3 that are inserted into each other along the first direction. An ejection mechanism 2 is provided on the connector body 1, and the ejection mechanism 2 is used to push the connector body 1 to separate from the plug. The ejection mechanism 2 includes a housing 21, an ejection block 22, a pushing part 23, and a linkage unit 24. The housing 21 is disposed on the connector body 1 corresponding to the side of the connector body 1. The ejection block 22 moves in the housing 21 along the first direction toward the socket 3. The pushing part 23 is disposed in the housing 21 corresponding to the ejection block 22. The linkage unit 24 is disposed on the housing 21 and is connected to the pushing part 23. The linkage unit 24 is used to switch the pushing part 23 from the first state to the second state. When the pushing part 23 is switched to the second state, the ejection block 22 moves in the housing 21 toward the socket 3. When the ejection block 22 moves to the first position 213 in the housing 21, the ejection block 22 drives the connector body 1 to separate from the plug.

[0027] Among them, the second state of the pushing part 23 is the release state. The pushing part 23 is unlocked, and the thrust generated after release pushes the top block 22 to move within the housing 21, and the top block 22 is located at the first position 213. Moreover, the space within the housing 21 is completely occupied by the pushing part 23, and the top block 22 cannot move within the housing 21. The first state of the pushing part 23 is the state to be released. The pushing part 23 is locked, and it can generate thrust after release to push the top block 22 to move within the housing 21. And the pushing part 23 in the state to be released only occupies part of the space within the housing 21, and there is space left within the housing 21 for the top block 22 to move. Therefore, when the pushing part 23 is in the state to be released, the top block 22 can be entirely within the housing 21, or partially within the housing 21, and located at the first position 213. The first direction is the connection direction of the connector body 1 and the socket 3. When the top block 22 is located at the first position 213, most of the position of the top block 22 is outside the housing 21, and the length of the part of the top block 22 outside the housing 21 is greater than the length of the part where the connector body 1 is inserted into the socket 3 when the connector body 1 is connected to the socket 3, so as to ensure that when the top block 22 is in the first position 213, the part of the connector body 1 inserted into the socket 3 can be pulled out from the socket 3.

[0028] During application, when it is necessary to pull out the connector body 1 from the socket 3, the pushing part 23 within the housing 21 is switched from the first state to the second state through the linkage unit 24. When the pushing part 23 is switched from the first state to the second state, the generated thrust can push the top block 22 to move within the housing 21 along the first direction to the first position 213. After the top block 22 moves to the first position 213, the thrust generated by the movement of the top block 22 will act on the socket 3, and the connector body 1 and the socket 3 will separate under the thrust of the top block 22, that is, under the action of the thrust, the connector body 1 separates from the socket 3, and there is no need for the user to manually pull out the connector body 1 from the socket 3. The pulling-out process is convenient and fast, and it avoids the damage of the metal contacts caused by the user shaking the connector when manually pulling out.

[0029] It can be known that when the connector body 1 is separated from the socket 3 through the ejection mechanism 2, there is no need for the user to manually pull out the connector body 1 from the socket 3. The pulling-out process is convenient and fast, which avoids the damage of the metal contacts caused by the user shaking the connector when manually pulling out, protects the metal contacts, and with the simple structure of the ejection mechanism 2 and the cooperation of structures such as the top block 22, the pushing part 23 and the linkage unit 24 in the ejection mechanism 2, the process of pulling out the connector body 1 from the socket 3 can also be simplified, and only the top block 22 needs to be moved, improving the pulling-out efficiency.

[0030] It should be noted that the thrust force when the pushing part 23 pushes the top block 22 to move can overcome the static friction force when the connector body 1 is connected to the socket 3. Therefore, after the top block 22 moves in the first direction towards the socket 3, the connector body 1 can be separated from the socket 3.

[0031] It should also be noted that the housing 21 is arranged on the connector body 1 corresponding to the four side surfaces of the connector body 1. Therefore, the corresponding numbers of the housing 21, the top block 22 and the pushing part 23 are four. Therefore, when the top block 22 pushes the connector body 1 to be separated from the socket 3, a linkage unit 24 is used to simultaneously switch the four pushing parts 23 from the first state to the second state, so that the four top blocks 22 can move synchronously towards the socket 3 under the action of the four pushing parts 23, so as to realize uniform force when the top block 22 pushes the connector body 1 to be separated from the socket 3, so as to avoid the situation that the metal contact is damaged when the connector body 1 is separated from the socket 3 due to uneven force, improve the separation effect of the connector body 1 and the socket 3, protect the metal contact, and the four pushing parts 23 drive the four top blocks 22 to move synchronously through a linkage unit 24, which also simplifies the ejection process and improves the work efficiency.

[0032] In a specific embodiment, the housing 21 is detachably arranged on the connector body 1, and the housing 21 is an assembled housing 21. Therefore, according to the static friction force when different connector bodies 1 are connected to the socket 3, a pushing part 23 that can generate different thrust forces can be arranged in the housing 21 before assembly, so that the thrust force generated when the top block 22 moves can meet different use requirements.

[0033] It can be understood that the detachable setting of the housing 21 and the assembly process of the housing 21 are well known to those skilled in the art, and will not be described in this embodiment.

[0034] Embodiment 2: The basic content is the same as that of Embodiment 1, and the difference is: Please refer to Figures 1-4 , in the connector body 1 of this embodiment, an installation groove 11 is opened, the housing 21 is arranged in the installation groove 11 along the first direction, and the number of the housing 21 on one side surface of the connector body 1 is at least one.

[0035] It should be noted that after the housing 21 is assembled, it can be connected to the connector body 1 through the installation groove 11 to reduce the space occupied by the housing 21, so that the structure is more compact, and setting a plurality of housing 21 to drive a plurality of top blocks 22 to move by the linkage unit 24 can also make the connector body 1 more stable when being separated from the socket 3.

[0036] On one side of the housing 21 facing the socket 3, there is a through - opening 211 for the top block 22 to penetrate. The top block 22 moves out of the housing 21 through the through - opening 211. A restricting member 221 is provided on the top block 22, and a restricting groove 212 corresponding to the restricting member 221 is opened on the inner side wall of the housing 21. The restricting member 221 is slidably connected to the restricting groove 212, and the restricting member 221 and the restricting groove 212 cooperate to limit the moving distance of the top block 22. When the top block 22 is at the first position 213, the restricting member 221 abuts against the inner side wall of the restricting groove 212 close to the socket 3.

[0037] During application, after the top block 22 is pushed by the pushing part 23, the top block 22 moves in the housing 21 in the first direction towards the socket 3. During the movement of the top block 22, the top block 22 will pass through the through - opening 211 and be guided by the through - opening 211. Also, during the movement, the top block 22 is restricted in its moving distance under the cooperation of the restricting member 221 and the restricting groove 212 to prevent the top block 22 from moving out of the housing 21, thus facilitating the reset of the moved top block 22 and facilitating the subsequent pulling - out operation of the connector body 1.

[0038] In a specific embodiment, the restricting member 221 is a rolling ball. A receiving groove for placing the rolling ball is opened on the top block 22. The length and width of the top block 22 are smaller than the length and width of the inner cavity of the housing 21. In this embodiment, when the top block 22 moves, it does not contact the inner wall of the housing 21, and the friction force received by the top block 22 during movement is reduced through the cooperation of the rolling ball and the restricting groove 212, so that the top block 22 moves more smoothly and the loss of the thrust generated on the pushing part 23 is reduced.

[0039] On one side of the socket 3 facing the connector body 1, a guiding groove 31 corresponding to the top block 22 is opened. The length and width of the top block 22 are respectively equal to the length and width of the inner cavity of the guiding groove 31. When the connector body 1 is connected to the socket 3, the top block 22 is inserted into the guiding groove 31.

[0040] It should be noted that the top block 22 can not only facilitate the separation of the connector body 1 and the socket 3, but also guide during the connection of the connector body 1 and the socket 3. When the connector body 1 is connected to the socket 3, the pushing part 23 is in the second state, and the top block 22 is at the first position 213. At this time, most of the top block 22 is located inside the housing 21. During connection, first move the top block 22 into the guiding groove 31, and then push the connector body 1 to connect with the socket 3. When the connector body 1 is connected to the socket 3, under the cooperation of the guiding groove 31, the top block 22 and the housing 21, it can be ensured that the connector body 1 and the socket 3 are aligned during connection, reducing the risk of offset and preventing the contact quality of the metal contacts from being affected due to offset.

[0041] It should be emphasized that when guiding the connection between the connector body 1 and the socket 3 through the cooperation of the top block 22 and the guiding groove 31, the top block 22 needs to be located at the first position 213 or partially outside the housing 21, so as to facilitate the guiding of the connection between the connector body 1 and the socket 3 through the cooperation of the top block 22 and the guiding groove 31.

[0042] In addition, when guiding the connection between the connector body 1 and the socket 3 through the cooperation of the guiding groove 31 and the top block 22, the pushing portion 23 can be in the first state or the second state. When the pushing portion 23 is in the second state, during the process of connecting the connector body 1 and the socket 3 through the cooperation of the guiding groove 31 and the top block 22, the top block 22 will also move into the housing 21 under the action of the extrusion force when the connector body 1 and the socket 3 are connected, and the pushing portion 23 will be switched from the second state to the first state, thus facilitating the subsequent pulling-out operation, without the need to separately switch the state of the pushing portion 23, effectively reducing the operation steps and improving the use effect.

[0043] Embodiment 3: The basic content is the same as that of Embodiment 1, the difference is that: Please refer to Figures 5-7 In this embodiment, the pushing portion 23 includes a first spring 231 and a push plate 232 connected in sequence. The first spring 231 is connected to the inner side wall of the housing 21, the push plate 232 is slidably connected in the housing 21, the first spring 231, the push plate 232 and the top block 22 are arranged in sequence along the first direction, and a clamping structure for clamping with the housing 21 is provided on the push plate 232. The clamping structure is connected to the linkage unit 24. When the pushing portion 23 is in the first state, both the first spring 231 and the push plate 232 are in a contracted state, and the clamping structure is clamped with the housing 21; when the pushing portion 23 is in the second state, both the first spring 231 and the push plate 232 are in a released state, the clamping structure is separated from the housing 21, and the push plate 232 also abuts against the top block 22 and the top block 22 is located at the first position 213.

[0044] During application, the clamping structure is clamped with the housing 21, so that both the first spring 231 and the push plate 232 are in a contracted state, that is, the pushing portion 23 is in the first state, as shown in Figure 5 ; when the clamping structure is released by the linkage unit 24, both the first spring 231 and the push plate 232 are in a released state, that is, the pushing portion 23 is in the second state, as shown in Figure 6As shown; specifically, after the clamping structure is separated from the housing 21 by the linkage unit 24, the pushing portion 23 can be switched from the first state to the second state. At the same time, the first spring 231 is switched from the contracted state to the released state to generate an elastic force, and the pushing block 232 is used to push the top block 22 to move towards the socket 3, so that the connector body 1 is separated from the socket 3 through the top block 22; when it is necessary to switch the pushing portion 23 from the second state to the first state, the top block 22 can be moved towards the inside of the housing 21. After the top block 22 moves, the top block 22 will squeeze the first spring 231 through the pushing block 232, so that the first spring 231 is switched from the released state to the contracted state. The pushing block 232 is also clamped with the housing 21 under the action of the clamping structure. At this time, both the first spring 231 and the pushing block 232 are switched from the released state in the second state to the contracted state in the first state, and are kept in the first state under the cooperation of the clamping structure and the housing 21; the pushing portion 23 is reset by the moving top block 22, making the reset of the pushing portion 23 more convenient.

[0045] Further, the clamping structure includes a clamping block 235 and a second spring 234 connected in sequence. A groove 233 is formed on the pushing block 232. The clamping block 235 is connected to the groove 233 through the second spring 234, and the clamping block 235 is telescopically movable in the groove 233 towards the linkage unit 24 along the second direction. A limiting hole 214 corresponding to the clamping block 235 is formed on the housing 21. When the pushing portion 23 is in the first state, the clamping block 235 is inserted into the limiting hole 214, and the clamping block 235 penetrates through the limiting hole 214 and is connected to the linkage unit 24; when the pushing portion 23 is in the second state, the clamping block 235 is separated from the linkage unit 24.

[0046] Specifically, the inner side wall of the limiting hole 214 facing the moving direction of the top block 22 is inclined, and the second direction is the direction of the clamping block 235 towards the linkage unit 24.

[0047] During application, the clamping block 235 is inserted into the limit hole 214 and penetrates outside the limit hole 214, so that the first spring 231 and the push plate 232 are both in a contracted state, that is, the pushing part 23 is in the first state. When the clamping block 235 is moved into the limit hole 214, the first spring 231 and the push plate 232 are both in a released state, that is, the pushing part 23 is in the second state. Specifically, after the clamping block 235 is moved into the limit hole 214 through the linkage unit 24, since the inner side wall of the limit hole 214 is inclined, the first spring 231 in the contracted state can be switched to the released state, and the push plate 232 and the clamping block 235 are moved toward the top block 22 by the elastic force, so as to push the top block 22 to move to the first position 213. At this time, the moved clamping block 235 abuts against the inner wall of the housing 21 under the action of the elastic force of the second spring 234. When it is necessary to reset the push plate 232 and the clamping block 235, the top block 22 can be moved to reset the push plate 232. And when pushing the push plate 232 to reset, the first spring 231 will also be squeezed to make the first spring 231 contract. When the push plate 232 is moved to align the clamping block 235 with the limit hole 214, the clamping block 235 will move into the limit hole 214 from the groove 233 under the action of the elastic force of the second spring 234 and position the push plate 232, so that the first spring 231 and the push plate 232 are both in a contracted state, facilitating the subsequent pulling-out work.

[0048] It should be noted that after the clamping block 235 is moved into the limit hole 214, the clamping block 235 will also squeeze the second spring 234 to make the second spring 234 contract.

[0049] Embodiment 4: The basic content is the same as that of Embodiment 3, and the difference lies in: Please refer to Figures 9-10 , in this embodiment, the linkage unit 24 includes a mounting frame 241 and a plurality of balls 242. The mounting frame 241 is arranged on the housing 21 corresponding to the clamping block 235, and the mounting frame 241 is connected to the connector body 1. The balls 242 are rotatably connected in the mounting frame 241. When the pushing part 23 is in the first state, the clamping block 235 penetrates and extends into the mounting frame 241 and abuts against the balls 242. A plurality of balls 242 between adjacent two clamping blocks 235 abut against each other in sequence. When any ball 242 that does not abut against the clamping block 235 moves a certain distance in the mounting frame 241, the clamping block 235 moves out of the mounting frame 241, and the pushing part 23 can be switched from the first state to the second state.

[0050] During application, when the state of the pushing part 23 is switched through the linkage unit 24, it is necessary to push any ball 242 that does not abut against the latch 235 to move a pushing distance within the mounting bracket 241. After the ball 242 moves, the ball 242 will squeeze the latch 235 through its outer peripheral surface, so that the latch 235 moves out of the mounting bracket 241 and moves into the limiting hole 214. After the latch 235 enters the limiting hole 214, under the action of the inclined inner part of the limiting hole 214, the latch 235 cannot lock the push plate 232, and the pushing part 23 is switched from the first state to the second state under the elastic force of the first spring 231, so that the top block 22 performs the separation work.

[0051] It should be noted that multiple balls 242 are sequentially abutted within the mounting bracket 241 to form a chain linkage. When any ball 242 is moved a pushing distance, its rolling action can evenly disperse the thrust to the adjacent balls 242, and finally synchronously push all the latches 235 into the limiting hole 214, avoiding the problems of jamming or uneven force caused by single-point force application.

[0052] It should be emphasized that the latch 235 abuts against the outer peripheral surface of the ball 242 close to the housing 21. After the ball 242 moves, the latch 235 can be squeezed into the limiting hole 214 through its arc-shaped outer peripheral surface.

[0053] Furthermore, a push block 243 is provided on the mounting bracket 241 corresponding to the latch 235, and a through hole for the push block 243 to penetrate is formed on the mounting bracket 241. The push block 243 moves towards the latch 235 in the second direction. The push block 243 is used to push the latch 235 out of the mounting bracket 241. The width and pushing distance of the push block 243 are equal to the width of several latches 235. A slope 244 is formed on the side of the push block 243 close to the latch 235 corresponding to the ball 242. After the push block 243 moves towards the latch 235, the ball 242 is pushed to move through the slope 244.

[0054] Even further, two support plates 245 are provided on the mounting bracket 241 corresponding to the push block 243. The push block 243 is slidably connected between the two support plates 245, and the push block 243 is clamped with the support plates 245. The push block 243 is normally located outside the mounting bracket 241.

[0055] During application, by pressing the push block 243, the push block 243 moves through the perforation into the mounting frame 241. After the push block 243 enters the mounting frame 241, it can push one of the clamping blocks 235 into the corresponding limiting hole 214. During the movement of the push block 243, it can also contact the corresponding ball 242 through its inclined surface 244 to squeeze the ball 242. When the push block 243 is moved into the mounting frame 241 to the maximum limit, all four clamping blocks 235 are moved into the corresponding limiting holes 214 under the action of the push block 243 and the ball 242, and the pushing part 23 switches from the first state to the second state; by using the push block 243 to move the clamping block 235 into the limiting hole 214, it is more convenient and fast, and only by pressing can the connector body 1 be separated from the socket 3 by moving the top block 22.

[0056] Further, the cross-sectional shape of the mounting frame 241 is in the shape of a double-square, and the length and width of the inner cavity of the mounting frame 241 are both equal to the diameter of the ball 242. The side of the connector body 1 in the first direction is an arc-shaped that fits the outer circumference of the ball 242.

[0057] It should be noted that several balls 242 are distributed in the mounting frame 241 with a double-square cross-section. After the balls 242 move, it is convenient to squeeze the clamping blocks 235 on different sides of the corresponding connector body 1 to improve the linkage effect. The arc-shaped edge on the connector body 1 can also make the balls 242 move more smoothly.
