Description

Technical Field

[0001] This invention belongs to the field of high-speed electrical connector technology, and specifically relates to a high-speed electrical connector with an anti-mismating structure. Background Technology

[0002] High-speed electrical connectors are core electronic components that meet the high-speed signal transmission requirements of modern electronic devices. The International Electrotechnical Commission defines their transmission rate as usually exceeding 1Gbps. Their core function is to achieve efficient data and energy transmission between devices while maintaining signal integrity. These connectors use metal shielding design and high dielectric strength insulation materials, which can effectively reduce electromagnetic interference and crosstalk. With snap-in or CPA locking mechanisms, they are suitable for harsh environments such as high vibration. When using existing high-speed electrical connectors, it is common to encounter situations where the plug is inserted backwards or at an angle to the socket. This can easily damage the internal contacts of the plug. Furthermore, during use, the plug may be accidentally pulled out of the socket, and this pulling force can also damage the contacts (for example, the high-speed electrical connectors on the surface of hospital electrocardiogram monitors, which require frequent use, and if the wires are pulled apart, it will affect the patient's treatment). Summary of the Invention

[0003] The purpose of this invention is to provide a high-speed electrical connector with an anti-mis-mating structure, which has the advantage of preventing unintentional damage to the internal contacts of the high-speed electrical connector.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a high-speed electrical connector with an anti-misinsertion structure, comprising a connecting plate, a socket being bolted to one side of the connecting plate, an anti-misinsertion component being provided on the surface of the connecting plate, a plug being detachably connected inside the anti-misinsertion component, a plurality of contacts being electrically connected inside the plug, the contacts being detachably connected to the socket, and an anti-detachment component being provided on the surface of the connecting plate.

[0005] Using the above technical solution, the connecting plate is connected to the machine surface, and the socket is embedded inside the connecting plate. Therefore, the socket is electrically connected to the machine. When the contact on the plug surface is inserted into the socket, the plug is placed inside the anti-misinsertion component. Because the anti-misinsertion component is set parallel to the socket, when the internal structure of the sliding anti-misinsertion component and the plug move to the position of the socket, the plug moves horizontally. In this way, when the plug is inserted into the socket, there will be no tilting. In addition, the anti-misinsertion component has a function to prevent the plug from being inserted backward. After the contact on the plug surface is successfully inserted into the socket, it will drive the anti-dislodgement component to fix the position of the plug. This can prevent the contact on the plug surface from being accidentally and forcibly pulled out of the socket during use.

[0006] The present invention is further configured such that: the anti-misinsertion component includes a mounting plate, the mounting plate is bolted to the surface of the connecting plate, and the connecting plate is in contact with one side of the socket; each of the four corners of one side of the connecting plate is bolted with a first spring rod, and two sets of the first spring rods are located inside the mounting plate; the piston ends of the four sets of the first spring rods are bolted to a fixing frame.

[0007] Using the above technical solution, when the fixed frame is pushed to move, the first spring rod will be compressed.

[0008] The present invention is further configured such that: a limiting rod is slidably sleeved on both sides of one end of the fixed frame, a sliding shell is welded to one end of the limiting rod, and the two sets of sliding shells are threaded together with positive and negative screw rods, and the positive and negative screw rods are rotatably connected to the fixed frame.

[0009] Using the above technical solution, when in use, the handle is rotated according to the specifications of the plug and socket. The handle will drive the positive and negative screws to rotate. In this way, the positive and negative screws will drive the two sets of sliding shells to move in opposite directions at the same time. The limiting rod is used to support and limit the movement of the sliding shells to prevent the sliding shells from rotating along with the rotation of the positive and negative screws.

[0010] The present invention is further configured such that: a rotating handle is welded to one end of the positive and negative lead screws, a moving groove is provided on one side of the sliding shell, a sliding plate is slidably connected inside the moving groove, and a telescopic plate is welded between the two sets of sliding plates, and the telescopic plate can extend and retract.

[0011] Using the above technical solution, and with the two sets of sliding shells moving, the two sets of sliding plates will move synchronously using the telescopic characteristics of the telescopic plate until the distance between the two sets of sliding shells and the two sets of sliding plates is exactly matched with the specifications of the plug and socket. This can be adapted to the use of various specifications of plugs and sockets. When the plug is installed between the two sets of sliding plates according to the plug position shown in the figure, the plug will not contact the cone, and the two sets of baffles will be parallel to the surface of the two sets of sliding shells. Then, the plug is slid by the baffles sliding inside the sliding shell. During the sliding process, the plug will drive the sliding plate and telescopic plate to move synchronously. Because the sliding plate is designed to be parallel to the socket, when the plug moves to the top of the socket, it is pressed forward.

[0012] The present invention is further configured such that: a hole is formed on the surface of one of the sliding plates, a slip ring is welded to the inner wall of the hole, a sliding column is slidably connected inside the slip ring, a circular plate is welded to the surface of the sliding column, and a telescopic spring is connected between the circular plate and the slip ring by a spring fixing member, and the telescopic spring is sleeved on the surface of the sliding column.

[0013] Using the above technical solution, when the cone is squeezed, it will drive the sliding column to move inside the hole, and the circular plate will stretch the telescopic spring. Similarly, when the cone stops being squeezed, the telescopic spring will drive the sliding column and the cone to move and reset.

[0014] The present invention is further configured such that: a cone is welded to one end of the sliding column, baffles are ultrasonically welded to both sides of the plug, and positioning holes are opened on both sides of the plug.

[0015] Using the above technical solution, since the surface of the cone is inclined, when the cone is squeezed, it will move into the hole and drive the sliding column and the circular plate to move synchronously inside the hole. This will cause the sliding column to press against the inner wall of the sliding shell after it has moved.

[0016] The present invention is further configured such that: the anti-fall-off component includes a vertical plate, and the vertical plate is provided in two sets, the two sets of vertical plates are respectively bolted to both ends of one side of the connecting plate, and two sets of second spring top rods are bolted to one side of the vertical plate.

[0017] Using the above technical solution, the second spring push rod is used to push the positioning block to move and position it inside the positioning hole.

[0018] The invention is further configured such that: the piston ends of the two sets of second spring top plates are bolted together with a positioning block, the positioning block has a groove inside, and a fixing rod is rotatably connected inside the positioning block.

[0019] Using the above technical solution, the fixing rod will cause the inclined plate to flip into the groove, which can protect the inclined plate.

[0020] The present invention is further configured such that: an inclined plate is welded to the surface of the fixing rod, a slider is welded to the surface of the fixing rod, and a threaded sleeve is slidably connected to the surface of the fixing rod.

[0021] By adopting the above technical solution, and with the threaded sleeve rotating, it will synchronously drive the slider to rotate, and the slider will drive the fixed rod to rotate. In this way, the fixed rod will drive the inclined plate to flip into the groove, which can protect the inclined plate.

[0022] The present invention is further configured such that: a sliding hole is provided on the surface of the threaded sleeve, and the sliding hole and the slider are slidably connected; both the sliding hole and the slider are located outside the positioning block; a threaded plate is threadedly connected to the surface of the threaded sleeve, and the threaded plate is welded to the positioning block; and several sets of anti-slip grooves are provided on the surface of the threaded sleeve.

[0023] Using the above technical solution, and if the high-speed electrical connector is not used for a long time, some dust and impurities will fall on the surface of the inclined plate. The dust and impurities will stick firmly and are difficult to remove. If there is dust or impurities that are difficult to remove on the surface of the inclined plate, when the fixed frame moves again using the first spring push rod and squeezes the inclined plate, it is difficult to make the inclined plate drive the positioning block to move due to the large resistance. Therefore, when the high-speed electrical connector is not in use, the anti-slip groove can be used to rotate the threaded sleeve (the anti-slip groove is used to prevent slippage when rotating the threaded sleeve). When the threaded sleeve rotates, because the threaded sleeve is threadedly connected to the threaded plate, the threaded sleeve will move outward.

[0024] In summary, the present invention has the following beneficial effects: 1. The fixed frame design allows the plug to be accurately inserted into the socket, avoiding damage to the contacts caused by the plug tilting. 2. The design of the cone, sliding column and telescopic spring can detect whether the plug is inserted backwards when it is plugged in, so as to avoid damage to the contact parts caused by the plug being inserted backwards. 3. The design of positioning blocks, inclined plates and positioning holes can fix the position of the plug during the insertion process, so as to prevent the plug from being accidentally pulled open, which would damage the contact parts and cause the equipment to stop running. 4. Through the design of the fixing rod, groove and inclined plate, the inclined plate can be stored in the groove when not in use, avoiding the surface friction caused by the inclined plate being contaminated. In this way, when the inclined plate is squeezed, it is difficult to easily move the positioning block to one side. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1: refer to Figure 1-9 A high-speed electrical connector with an anti-misinsertion structure includes a connecting plate 1, a socket 3 is bolted to one side of the connecting plate 1, an anti-misinsertion component 5 is provided on the surface of the connecting plate 1, a plug 2 is detachably connected inside the anti-misinsertion component 5, a number of contacts 4 are electrically connected inside the plug 2, the contacts 4 and the socket 3 are detachably connected, and an anti-detachment component 6 is provided on the surface of the connecting plate 1.

[0029] Brief description of usage: Connector 1 is attached to the surface of the machine, and socket 3 is embedded inside connector 1. Therefore, socket 3 is electrically connected to the machine. When inserting the contact 4 on the surface of plug 2 into socket 3, plug 2 is placed inside anti-misinsertion component 5. Because anti-misinsertion component 5 is parallel to socket 3, when the internal structure of anti-misinsertion component 5 is slidable and plug 2 moves to the position of socket 3, plug 2 moves horizontally. This prevents tilting when plug 2 is inserted into socket 3. Anti-misinsertion component 5 also has a function to prevent plug 2 from being inserted backwards. After the contact 4 on the surface of plug 2 is successfully inserted into socket 3, it will drive anti-dislodgement component 6 to fix the position of plug 2. This can prevent the contact 4 on the surface of plug 2 from being accidentally pulled out of socket 3 during use.

[0030] Example 2: Based on Example 1, and referring to Figure 1-9 The anti-misinsertion component 5 includes a mounting plate 516, which is bolted to the surface of the connecting plate 1. The connecting plate 1 is attached to one side of the socket 3. Four corners of one side of the connecting plate 1 are bolted with first spring push rods 503, two of which are located inside the mounting plate 516. The piston ends of the four sets of first spring push rods 503 are bolted to a fixing frame 505. Limiting rods 504 are slidably sleeved inside both sides of one end of the fixing frame 505. A sliding shell 506 is welded to one end of each limiting rod 504. Both sets of sliding shells 506 are threaded with positive and negative threaded rods 515, which are rotatably connected to the fixing frame 505. A handle 514 is welded to one end of each positive and negative threaded rod 515. A movable groove 518 is provided on one side, and a sliding plate 507 is slidably connected inside the movable groove 518. A telescopic plate 508 is welded between two sets of sliding plates 507, and the telescopic plate 508 can be extended and retracted. A hole 513 is provided on the surface of one set of sliding plates 507. A slip ring 510 is welded to the inner wall of the hole 513. A sliding column 517 is slidably connected inside the slip ring 510. A circular plate 512 is welded to the surface of the sliding column 517. A telescopic spring 511 is connected to the circular plate 512 and the slip ring 510 through a spring fixing component, and the telescopic spring 511 is sleeved on the surface of the sliding column 517. A cone 509 is welded to one end of the sliding column 517. Baffles 501 are ultrasonically welded on both sides of the plug 2. Positioning holes 502 are provided on both sides of the plug 2. The anti-fall-off component 6 includes a vertical plate 601, and two sets of vertical plates 601 are provided. The two sets of vertical plates 601 are bolted to both ends of one side of the connecting plate 1. Two sets of second spring push rods 602 are bolted to one side of the vertical plate 601. The piston ends of the two sets of second spring push plates are bolted to a positioning block 603. The positioning block 603 has a groove 611 inside, and a fixing rod 610 is rotatably connected inside the positioning block 603. An inclined plate 604 is welded to the surface of the fixing rod 610. A slider 608 is welded to the surface of the fixed rod 610, and a threaded sleeve 605 is slidably connected to the surface of the fixed rod 610. A sliding hole 609 is opened on the surface of the threaded sleeve 605, and the sliding hole 609 and the slider 608 are slidably connected. Both the sliding hole 609 and the slider 608 are located outside the positioning block 603. A threaded plate 607 is threadedly connected to the surface of the threaded sleeve 605, and the threaded plate 607 is welded to the positioning block 603. Several sets of anti-slip grooves 606 are opened on the surface of the threaded sleeve 605.

[0031] Brief description of usage: During use, rotate the handle 514 according to the specifications of plug 2 and socket 3. The handle 514 will drive the forward and reverse screws 515 to rotate. This causes the two sets of sliding housings 506 to move simultaneously in opposite directions. The limiting rod 504 supports and limits the movement of the sliding housings 506, preventing them from rotating along with the forward and reverse screws 515. During the movement of the two sets of sliding housings 506, the two sets of sliding plates 507 will move synchronously using the telescopic characteristic of the telescopic plate 508 until the distance between the two sets of sliding housings 506 and the two sets of sliding plates 507 exactly matches the specifications of plug 2 and socket 3. This allows for compatibility with various specifications of plug 2 and socket 3. Figure 1The placement of plug 2, as shown, means that when plug 2 is installed between the two sets of sliding plates 507, plug 2 will not contact cone 509, and the two sets of baffles 501 will be parallel to each other on the surfaces of the two sets of sliding shells 506. Then, plug 2 slides by sliding the baffles 501 inside the sliding shells 506. During this sliding process, plug 2 will drive the sliding plates 507 and telescopic plates 508 to move synchronously. Because the sliding plates 507 are designed to be parallel to socket 3, when plug 2 moves above socket 3, it is pressed forward. During this pressing process, baffles 501 will push the fixing frame 505 to compress and move the first spring rod 503, and the fixing frame 50... 5 will press the inclined plate 604. When the inclined plate 604 is pressed, because the inclined plate 604 is made of tempered glass and has a relatively smooth surface, the positioning block 603 will move outward by a distance using the second spring rod 602. When the plug 2 inserts the contact 4 into the socket 3, the second spring rod 602 will immediately push the positioning block 603 forward. This will position the positioning block 603 and the inclined plate 604 inside the positioning hole 502, thus fixing the position of the plug 2 and effectively preventing the plug 2 from being accidentally pulled open. Furthermore, since the fixing frame 505 and the socket 3 are set parallel, it avoids damage to the contact 4 when the plug 2 is inserted into the socket 3 at an angle. Furthermore, if the high-speed electrical connector is not used for a long time, some dust and impurities will accumulate on the surface of the inclined plate 604. This dust and impurities tend to adhere firmly and are difficult to remove. If the surface of the inclined plate 604 is covered with stubborn dust or impurities, when the fixing frame 505 moves again using the first spring push rod 503 to press against the inclined plate 604, the resistance is too high, making it difficult for the inclined plate 604 to move the positioning block 603. Therefore, when the high-speed electrical connector is not in use, the threaded sleeve 605 can be rotated using the anti-slip groove 606 (the anti-slip groove 606 is used to prevent rotation). (Slippage occurs when the threaded sleeve 605 is in motion). When the threaded sleeve 605 rotates, because the threaded sleeve 605 is threadedly connected to the threaded plate 607, the threaded sleeve 605 will move outward. Therefore, the threaded sleeve 605 and the sliding hole 609 will slide outward on the surfaces of the fixed rod 610 and the slider 608, respectively. During the rotation of the threaded sleeve 605, the slider 608 will rotate synchronously, and the slider 608 will drive the fixed rod 610 to rotate. In this way, the fixed rod 610 will drive the inclined plate 604 to flip into the groove 611, which can protect the inclined plate 604. And as Figure 1As shown, if plug 2 is placed upside down, the wider end of plug 2 will press against cone 509. Since the surface of cone 509 is inclined, when cone 509 is pressed, it will move into hole 513, and will drive slide column 517 and circular plate 512 to move synchronously inside hole 513. This will cause slide column 517 to press against inner wall of sliding shell 506. Because the weight of telescopic plate 508 and sliding plate 507 is twice the strength of telescopic spring 511, the telescopic plate 508 and sliding plate 507 will not move during the process of pushing cone 509 and slide column 517. When slide column 517 presses against inner wall of sliding shell 506, the force required to slide slide column 517 is further strengthened. Therefore, when pushing plug 2, a noticeable force will be felt, which will indicate that plug 2 is inserted backwards, thus avoiding damage to contact 4 caused by plug 2 being inserted backwards.

[0032] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
