Description

Technical Field

[0001] The present invention relates to the technical field of hubs, and in particular to a HUB interface structure with a dual design of preventing mis-insertion and magnetic locking. Background Art

[0002] A HUB is a hardware device used to connect multiple network devices or electronic devices. It is essentially a multi-port signal repeater. A HUB is a key component that enables device expansion and multi-functional connection. It is widely used in various electronic devices such as computers, tablets, mobile phones, and industrial control equipment.

[0003] In the existing technology, the HUB interface is generally directional, and the user needs to carefully align the interface direction when inserting. Due to the small interface, the HUB may be inserted upside down in low light, small space or when the user is in a hurry, causing wear and tear on the contact end of the HUB and the USB. Long-term incorrect insertion will cause damage to the HUB interface, device port and even internal circuits. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a HUB interface structure with a dual design of magnetic attraction and locking to prevent mis-insertion, which can effectively solve the problem in the prior art that the HUB interface is generally directional, requiring the user to carefully align the interface direction when inserting. Due to the small interface, the HUB may be inserted upside down in insufficient light, small space or when the user is in a hurry, causing wear on the contact end of the HUB and the USB. Long-term mis-insertion may cause damage to the HUB interface, device port and even internal circuit.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a HUB interface structure with a dual design of magnetic attraction and locking to prevent mis-insertion, comprising:

[0007] A housing, wherein the housing is fixedly connected to a wiring port via a sealing plate disposed inside the housing;

[0008] Terminal block;

[0009] A threading seat is embedded in the housing and fixedly connected to the side of the sealing plate away from the wiring port. A cavity is provided inside the threading seat that is connected to the interior of the wiring port.

[0010] Among them, the positioning part includes a vertical groove opened on the outer surface of the threading seat, and the interior of the threading seat is respectively provided with an annular groove and a horizontal groove connected to the interior of the vertical groove. The vertical groove, annular groove and horizontal groove are distributed in sequence from the outside to the inside, and the angle between the vertical groove and the horizontal groove is ninety degrees. The outer surface of the terminal head is fixedly connected to a limiting column that fits with the inner wall surface of the vertical groove.

[0011] Furthermore, the positioning parts are provided in several groups, each group is provided with two limiting columns, and the two limiting columns are symmetrically distributed on both sides of the terminal head; each group is provided with two vertical grooves and horizontal grooves, and the two vertical grooves and horizontal grooves are symmetrically distributed along the axis of the cavity.

[0012] Furthermore, an annular magnet is provided inside the cavity, and two annular magnets are provided and symmetrically distributed along the axis of the cavity, and the magnetic poles of the two annular magnets are designed in opposite directions. The outer surface of the terminal head is fixedly connected with a magnetic block that fits the outer surface of the annular magnet, and two magnetic blocks are provided and symmetrically distributed on both sides of the terminal head, and the magnetic poles of the two magnetic blocks are designed in opposite directions.

[0013] Furthermore, the inner wall surface of the vertical groove adopts a conical surface design, and the angle between the magnetic block and the limiting column is ninety degrees.

[0014] Furthermore, the dustproof part includes a support seat fixedly connected to the outer surface of the sealing plate, two support seats are provided and symmetrically distributed along the wiring port, a rotating rod is provided on the outer surface of the support seat, the support seat is fixedly connected to the middle part of the rotating rod by rotating the shaft rod inside it, the outer end of the rotating rod is rotatably connected to the connecting rod, two connecting rods are provided and distributed in a circular array on both sides of the rotating rod, and the end of the connecting rod away from the rotating rod is rotatably connected to a dustproof plate that slides in contact with the outer surface of the sealing plate.

[0015] Furthermore, an angle rod is fixedly connected to the inner wall surface of the cavity, and the angle rod is connected to a torsion spring via a rotating shaft fixed on its outer surface. Two rotating shafts are provided and symmetrically distributed at both ends of the angle rod. The outer surface of a rotating shaft close to the wiring port is provided with a long rod connected to the inside of the torsion spring, and the outer surface of a rotating shaft away from the wiring port is provided with a short rod connected to the inside of the torsion spring. The middle part of the long rod is rotatably connected to a movable rod, and the end of the movable rod away from the long rod is rotatably connected to the top end of the short rod, and the angle rod and the movable rod are placed parallel to each other.

Without the need for precise manual adjustment, the wiring connector can be quickly and accurately positioned and angled, simplifying the operation process, improving convenience and accuracy, and eliminating the problem of repeated alignment and adjustment required in traditional docking, thereby accelerating connection efficiency. In low-light conditions, confined spaces, or when the user is in a hurry, the wiring connector will not be inserted upside down, causing wear and tear on the contact ends of the hub and USB, or even damage to the internal circuitry.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example:

[0033] See also Figures 1-8 The present invention provides a technical solution: a HUB interface structure with a dual design of magnetic locking to prevent mis-insertion, comprising:

[0034] The housing 1 is fixedly connected to a wiring port 12 via a sealing plate 11 disposed inside the housing;

[0035] Terminal 2;

[0036] The threading seat 3 is embedded in the housing 1 and is fixedly connected to the side of the sealing plate 11 away from the wiring port 12. A cavity 30 is provided inside the threading seat 3 and is connected to the interior of the wiring port 12. A positioning member 31 is provided inside the threading seat 3 to prevent the wiring head 2 from being inserted incorrectly. A dustproof member 32 is provided inside the cavity 30.

[0037] Among them, the positioning part 31 includes a vertical groove 311 opened on the outer surface of the threading seat 3, and the interior of the threading seat 3 is respectively provided with an annular groove 312 and a horizontal groove 313 connected to the interior of the vertical groove 311. The vertical groove 311, the annular groove 312 and the horizontal groove 313 are distributed in sequence from the outside to the inside, and the angle between the vertical groove 311 and the horizontal groove 313 is ninety degrees. The outer surface of the terminal head 2 is fixedly connected to a limiting column 314 that fits with the inner wall surface of the vertical groove 311.

[0038] There are several groups of positioning members 31, each group of limiting columns 314 is provided with two, and the two limiting columns 314 are symmetrically distributed on both sides of the terminal head 2, and each group of vertical grooves 311 and horizontal grooves 313 is provided with two, and the two vertical grooves 311 and horizontal grooves 313 are symmetrically distributed along the axis of the cavity 30.

[0039] An annular magnet 315 is provided inside the cavity 30. Two annular magnets 315 are provided and are symmetrically distributed along the axis of the cavity 30. The magnetic poles of the two annular magnets 315 are designed in opposite directions. The outer surface of the terminal head 2 is fixedly connected to a magnetic block 316 that fits the outer surface of the annular magnet 315. Two magnetic blocks 316 are provided and are symmetrically distributed on both sides of the terminal head 2. The magnetic poles of the two magnetic blocks 316 are designed in opposite directions.

[0040] The inner wall surface of the vertical groove 311 adopts a conical surface design, and the angle between the magnetic block 316 and the limiting column 314 is ninety degrees.

[0041] The dustproof part 32 includes a support seat 321 fixedly connected to the outer surface of the sealing plate 11. There are two support seats 321 and they are symmetrically distributed along the wiring port 12. A rotating rod 322 is provided on the outer surface of the support seat 321. The support seat 321 is fixedly connected to the middle part of the rotating rod 322 by rotating the shaft 3210 inside it. The outer end of the rotating rod 322 is rotatably connected to the connecting rod 323. There are two connecting rods 323 and they are distributed in a circular array on both sides of the rotating rod 322. The end of the connecting rod 323 away from the rotating rod 322 is rotatably connected to a dustproof plate 324 that slides in contact with the outer surface of the sealing plate 11.

[0042] The inner wall surface of the cavity 30 is fixedly connected to a corner rod 33, and the corner rod 33 is connected to a torsion spring 332 through a rotating shaft 331 fixed on its outer surface. There are two rotating shafts 331 and they are symmetrically distributed at both ends of the corner rod 33. The outer surface of the rotating shaft 331 on the side close to the wiring port 12 is sleeved with a long rod 333 connected to the inside of the torsion spring 332, and the outer surface of the rotating shaft 331 on the side away from the wiring port 12 is sleeved with a short rod 334 connected to the inside of the torsion spring 332. The middle part of the long rod 333 is rotatably connected to a movable rod 335, and the end of the movable rod 335 away from the long rod 333 is rotatably connected to the top of the short rod 334, and the corner rod 33 and the movable rod 335 are placed parallel to each other.

[0043] The shaft 3210 is fixedly connected to a connecting column 336 that fits the outer surface of the long rod 333 through a connecting arm arranged on the side away from the rotating rod 322. The weight of the dustproof plate 324 located above is greater than the weight of the dustproof plate 324 located below.

[0044] A placement groove 34 is provided inside the threading seat 3, and a reciprocating column 341 is fixedly connected to the side of the annular magnet 315 close to the outer shell 1. The outer end of the reciprocating column 341 extends to the inside of the placement groove 34 and is fixedly connected to a ring plate 342. A spring 343 is sleeved on the circumferential outer surface of the reciprocating column 341.

[0045] The gravity of the dustproof plate 324 located above is greater than the gravity of the dustproof plate 324 located below. The gravity of the dustproof plate 324 located above cooperates with the torque of the rotating rod 322 and the connecting rod 323, so that in the absence of external force, the upper and lower dustproof plates 324 automatically close to cover the wiring port 12.

[0046] In actual use, the housing 1 is provided with a plurality of wiring ports 12, each corresponding to a cavity 30. Each wiring port 12 is provided with two dustproof plates 324, which are symmetrically arranged vertically around the support base 321. The combined height and area of ​​the two dustproof plates 324 are greater than the height and area of ​​the wiring port 12. A sealing strip is provided on the adjacent surfaces of the two dustproof plates 324 in each group.

[0047] In the initial state, the upper dust shield 324 of the dust shield 32 is heavier than the lower dust shield 324. The upper and lower dust shields 324 automatically close under their own weight and the torque of the rotating rod 322 and the connecting rod 323. The adjacent surfaces of the upper and lower dust shields 324 fit tightly together, completely covering the wiring port 12 and preventing dust and other foreign matter from entering. In this state, the rotating rod 322 is horizontally positioned, and the end of the connecting rod 323 away from the rotating rod 322 is pivotally connected to the side of the dust shield 324. The two connecting rods 323 are parallel, and the direction of the connecting post 336 is the same as the direction of the end of the rotating rod 322 near the wiring port 12. At this time, the connecting post 336 and the centerline of the shaft 3210 are in the same horizontal plane.

[0048] The angled rod 33 is fixed to the threading seat 3. The angled rod 33 is located below the notch of the horizontal slot 313 and is fixedly connected to the inner wall surface of the cavity 30. A rotating shaft 331 is provided at each end of the angled rod 33. A torsion spring 332 is sleeved on the outer surface of the rotating shaft 331 on the side closest to the support seat 321, which is connected to the interior of the long rod 333. A torsion spring 332 is sleeved on the outer surface of the rotating shaft 331 on the side away from the support seat 321, which is connected to the interior of the short rod 334. The long rod 333 and the short rod 334 are always parallel to each other, and the angled rod 33 and the movable rod 335 are also always parallel to each other. Under the action of the torsion spring 332, the long rod 333 and the short rod 334 are both tilted, forming a certain angle with the angled rod 33. The angled rod 33 and the movable rod 335 are separated, and the short rod 334, the long rod 333, and the movable rod 335 are vertically extended into the interior of the horizontal slot 313.

[0049] Two annular magnets 315 are symmetrically arranged vertically within cavity 30, with opposite magnetic poles. Due to their large distance, they are not affected by each other. The lower end of spring 343 abuts against the bottom of the inner wall of placement slot 34. The spring 343 pushes ring plate 342 into contact with the inner wall of housing 1. In this state, annular magnets 315 abut against the inner wall of cavity 30.

[0050] Insert terminal 2 into terminal port 12:

[0051] Twist the terminal block 2 at a certain angle so that the two limiting posts 314 on the outer surface of the terminal block 2 are distributed up and down, and then insert the terminal block 2 into the cavity 30. During the insertion process, the limiting posts 314 follow the vertical groove 311 to enter the cavity 30. Since the vertical groove 311 adopts a conical surface design, the limiting posts 314 allow a certain range of position error when inserted, and the position is gradually corrected as the insertion depth increases. When the limiting posts 314 on the outer surface of the terminal block 2 reach the intersection of the vertical groove 311 and the annular groove 312, the terminal block 2 is no longer tightly gripped and is loosened for a distance. The magnetic block 316 on the outer surface of the terminal block 2 is automatically rotated and positioned under the action of the annular magnet 315 inside the cavity 30, determining the correct insertion direction of the terminal block 2.

[0052] Two annular magnets 315 (with opposite magnetic poles) symmetrically distributed along the axis of cavity 30 attract each other with two magnetic blocks 316 (with opposite magnetic poles) symmetrically distributed on the outer surface of connector 2. One annular magnet 315 with a north pole attracts one magnetic block 316 with a south pole, and the other annular magnet 315 with a south pole attracts one magnetic block 316 with a north pole. Under the influence of magnetic force, connector 2 and retaining post 314 engage with annular groove 312 and rotate 90 degrees clockwise or counterclockwise, automatically confirming the insertion angle of connector 2. The outer end of retaining post 314 features an arc design, which reduces friction when in contact with the inner walls of annular groove 312, horizontal groove 313, and vertical groove 311.

[0053] At this time, the terminal head 2 is in a horizontal position, the limiting posts 314 are distributed in the left and right directions of the terminal head 2, and the magnetic blocks 316 are distributed in the up and down directions of the terminal head 2 (the annular magnets 315 are distributed in the up and down directions inside the cavity 30). Under the action of the magnetic connection, the limiting posts 314 are at the junction of the annular groove 312 and the horizontal groove 313.

[0054] The process of opening the dust cover 324:

[0055] The force applied to the connector 2 toward the interior of the wiring port 12 continues, and the limiting post 314 follows it and slides in contact with the interior of the horizontal slot 313. Since the short rod 334 is in an extended state, forming a certain angle with the angled rod 33, the outer surface of the short rod 334 is extended within the horizontal slot 313. When the limiting post 314 is inserted, it pushes the short rod 334 in the cavity 30 to rotate about the rotation axis 331, and the torsion spring 332 is compressed. The angled rod 33, the long rod 333, the short rod 334, and the movable rod 335 form a parallelogram mechanism. The long rod 333 and the short rod 334 rotate synchronously about their respective internal rotation axes 331 toward the wiring port 12 until the outer surfaces of the long rod 333 and the short rod 334 are in contact with the outer surface of the angled rod 33. The long rod 333, the short rod 334, and the movable rod 335 are all in a horizontal position and in a retracted state as a whole, no longer blocking the interior of the horizontal slot 313.

[0056] During this process, the middle portion of the long rod 333 is rotatably connected to the movable rod 335. During this rotation, the end of the long rod 333 away from the angled rod 33 comes into contact with the outer surface of the connecting post 336, driving the connecting post 336 to rotate synchronously. The connecting post 336 is fixedly connected to the rotating rod 322 via the shaft 3210. The rotating rod 322 rotates around the shaft 3210 during this process, and then drives the dustproof plate 324 to slide upward and downward through the connecting rod 323, exposing the wiring port 12 and completing the wiring preparation (the dustproof plate 324 is in contact with the outer surface of the sealing plate 11, and the two dustproof plates 324 can only move in the same direction or opposite directions in the vertical direction).

[0057] At this point, the retaining post 314 remains in contact with the upper surface of the short rod 334, and a small gap still exists between the outer end of the connector 2 and the surface of the dust shield 324. As the connector 2 continues to be inserted, the retaining post 314 slides within the horizontal slot 313 and contacts the upper surface of the movable rod 335. During this process, the torsion spring 332 on the outer surface of the rotating shaft 331 remains compressed, the movable rod 335 is in contact with the outer surface of the angled rod 33, and the dust shield 32 remains open. As the connector 2 continues to be inserted, it passes through the two open dust shields 324 and smoothly enters the interior of the wiring port 12.

[0058] The magnetic block 316 above the terminal block 2 has opposite magnetic poles to the annular magnet 315 above it, and the two are attracted to each other under the action of magnetic force; the magnetic block 316 below the terminal block 2 has opposite magnetic poles to the annular magnet 315 below it, and the two are attracted to each other under the action of magnetic force. The magnetic block 316 adopts a circular arc block design that fits the annular magnet 315. After the terminal block 2 is inserted into the wiring port 12, the annular magnet 315 at the top cooperates with the reciprocating column 341 and the ring plate 342 to slide downward, and the spring 343 is compressed until the annular magnet 315 is completely attracted to the outer surface of the magnetic block 316 above the terminal block 2; the annular magnet 315 at the bottom slides upward until the annular magnet 315 is completely attracted to the outer surface of the magnetic block 316 above the terminal block 2. The locking force provided by the magnetic attraction can prevent the terminal block 2 from accidentally falling off due to external force or shaking during use, ensuring the stability of the connection. After the terminal block 2 is stably placed, related operations such as data transmission or power supply can be carried out.

[0059] The process of pulling out terminal 2:

[0060] After use, the terminal block 2 is pulled outward, and the outer surface of the limiting post 314 initially slides against the upper surface of the movable rod 335. During this process, the dust cover 324 remains open and does not interfere. After the terminal block 2 moves a distance away from the wiring port 12, the magnetic block 316 disengages from the annular magnet 315, and the annular magnet 315 returns to its initial contracted state under the action of the spring 343. After the outer surface of the limiting post 314 passes the short rod 334 and reaches the junction of the horizontal groove 313 and the annular groove 312, the short rod 334 and the movable rod 335 are no longer suppressed and rotate upward under the action of the torsion spring 332, returning to the expanded state and blocking the inside of the notch of the horizontal groove 313. Correspondingly, after the connecting column 336 loses the squeezing effect of the long rod 333, the two dustproof plates 324 are closed under the action of the gravity of the dustproof plate 324 located above. At this time, the outer end of the terminal head 2 has been completely separated from the terminal port 12 and is outside the dustproof plate 324, avoiding wear on the metal coating on the outer end surface of the terminal head 2 due to the closure of the dustproof plate 324 during the pull-out process.

[0061] In summary, the HUB interface has the following advantages when plugging in the connector 2:

[0062] Advantage 1: Each wiring port 12 is equipped with two upper and lower dust shields 324. Their combined height and area are larger than those of the wiring port 12. Sealing strips are provided on adjacent surfaces, allowing them to fit tightly in their initial state, completely covering the wiring port 12 and effectively preventing the entry of dust and other foreign matter. When the device is idle, dust and other foreign matter are significant factors affecting its performance and service life. By increasing the coverage area of ​​the dust shields 324 and providing sealing strips, dust is minimized from contacting the wiring port 12, ensuring the cleanliness of the interior of the wiring port 12 and maintaining normal operation of the device.

[0063] Advantage 2: When inserting the terminal block 2, it is only necessary to place the outer surface of the side where the limiting post 314 is located horizontally, without the need to accurately align the insertion direction. After the limiting post 314 reaches the inside of the annular groove 312, the two annular magnets 315 in the cavity 30 and the two magnetic blocks 316 on the outer surface of the terminal block 2 attract each other with opposite poles. By using the magnetic force, as long as the limiting post 314 enters the annular groove 312, the magnetic force will force the terminal block 2 to rotate to the correct position. The positioning member 31 ensures that the terminal block 2 is correctly connected to the pins, contacts and other key parts inside the wiring port 12. Without manual precise adjustment, the positioning and angle confirmation of the terminal block 2 can be completed quickly and accurately, simplifying the operation process, improving the convenience and accuracy of operation, solving the problem of repeated matching and adjustment required for traditional docking, and accelerating connection efficiency.

[0064] Advantage 3: After the terminal block 2 is inserted into the wiring port 12, the upper and lower annular magnets 315 and the upper and lower magnetic blocks 316 of the terminal block 2 attract each other respectively. The locking force provided by the magnetic attraction can prevent the terminal block 2 from accidentally falling off due to external forces such as shaking during use, thereby ensuring the stability of the connection. During the use of the device, it will be disturbed by various external forces, such as vibration and collision, which can easily cause the terminal block 2 to loosen or even fall off, affecting the normal operation of the device. The magnetic locking design of the annular magnet 315 and the magnetic block 316 uses a strong magnetic force to fix the terminal block 2 in the wiring port 12 and the cavity 30, effectively resisting external interference, ensuring the stability of the connection, and ensuring the smooth progress of related operations such as data transmission or power supply of the device.

[0065] Advantage 4: When the outer end of the terminal block 2 is not in contact with the surface of the dustproof plate 324, the short rod 334 is pushed to rotate by the limiting column 314, driving the long rod 333 and the movable rod 335 to move. Then, the dustproof plate 324 is completely slid open upward and downward by the connecting column 336, the rotating rod 322 and the connecting rod 323. The dustproof plate 324 is automatically pre-opened during the plugging process to avoid collision. When the dustproof plate 324 needs to be closed, the limiting column 314 passes the short rod 334, and the short rod 334 and the movable rod 335 rotate upward and unfold under the action of the torsion spring 332. The connecting column 336 loses its squeezing effect. The weight of the dustproof plate 324 located above is greater. Under the action of its gravity, the two dustproof plates 324 move towards each other, and the adjacent surfaces of the two are in contact, in a closed state, isolating the terminal port 12 from external dust and ensuring cleanliness. The dust guard 32 automatically opens and closes the dust guard 324, eliminating the need for additional manual operation and improving ease of use. Before the connector 2 arrives, the dust guard 324 opens to its maximum angle, preventing damage to the connector 2 from colliding with the dust guard 324 and ensuring a smooth docking process. When the connector 2 is removed, the dust guard 324 quickly closes after the connector 2 is completely detached, preventing wear on the outer surface of the connector 2. This extends the connector 2's service life, reduces the risk of poor contact or short circuits due to wear, and improves product reliability.
