Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a dual-slot plug connector. Background Technology

[0002] A dual-slot plug-in connector is a connection device with two independent slots. It belongs to the category of electrical or electronic connectors and is mainly used to realize signal and power transmission between circuits or devices. Its structure typically includes an insulating shell, conductive contacts, and fixing components. Different plugs or components can be connected to the two slots at the same time, supporting parallel connection and improving space utilization efficiency. It is suitable for scenarios that require multiple inputs and outputs, such as power distribution, industrial control equipment, and consumer electronics. It can simplify wiring and enhance connection stability. Some products have anti-misinsertion and wear-resistant characteristics to ensure safety and reliability in use. It is an important component for realizing modular connection.

[0003] A search revealed Chinese Patent Publication No. CN212114172U, which discloses a dual-slot straight-insertion board-to-board connector. The connector includes a base, with symmetrically arranged connecting slots on the center of both sides of the base. Guide rods are symmetrically fixed to the center of the inner walls of the two connecting slots on opposite sides. Limiting rings are symmetrically arranged on opposite sides of the inner cavities of the two connecting slots. Connecting posts are symmetrically arranged in the center of the inner cavities of the two connecting slots. Compression springs are symmetrically sleeved on the center of the two connecting posts. Anti-detachment rings are symmetrically sleeved on the opposite ends of the two connecting posts. Guide slots are symmetrically arranged in the center of the opposite sides of the two connecting posts. Pressure plates are symmetrically arranged on both sides of the base, and buffer pads are symmetrically fixed to the top of the opposite sides of the two pressure plates. This dual-slot straight-insertion board-to-board connector stabilizes the board's mating structure by fixing the board's pins. The opening force of the compression springs pulls the pressure plates to fix the board, providing a stable mounting foundation.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the use of modular industrial equipment, data centers, and server racks, when users frequently plug and unplug dual-slot connectors, excessive force can cause the elastic contact to permanently fail due to excessive deformation, while insufficient force can lead to an abnormal increase in contact resistance. If the plugging process lacks buffering, rigid collisions can cause localized stress concentration and accelerate terminal wear. Although existing technologies increase the number of springs to strengthen the fixation, they still cannot solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a dual-slot plug-in connector, which can effectively solve the problem of terminal deformation or contact failure caused by improper insertion and extraction force in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a dual-slot plug-in connector, including a connector body and a dual-slot body. A slot is provided on the outer side of the connector body, and the dual-slot body is inserted into the slot. Buffer ejection components are provided on both sides of the outer side of the slot. Snap-fit ​​limiting components are provided on both sides of the top and bottom outer sides of the inner wall of the slot. Each snap-fit ​​limiting component includes a slot, and a limiting spring is provided on the inner wall of the slot. Four sets of limiting springs are provided, and the four sets of limiting springs are arranged at equal distances. A positioning plate is installed at one end of each limiting spring, and a limiting block is installed on the inner side of the positioning plate. A pressing block is installed on the inner side of the dual-slot body, and a limiting groove is provided on the outer side of the pressing block. The surface of the limiting block is inserted into the interior of the limiting groove.

[0008] The buffer ejection assembly includes a buffer groove, and a buffer spring is installed on the inner side of the inner wall of the buffer groove. There are four sets of buffer springs, which are arranged at equal distances. A push block is installed on the other end of the buffer spring. An electromagnetic block is installed on the outer side of the inner wall of the slot. The other end of the limiting spring is installed on the inner side of the electromagnetic block. The positioning plate is made of iron.

[0009] With the above scheme, the slot is inserted into the dual plug-in board body. The buffer spring and the push block provide elastic buffering during insertion and removal to absorb the impact force and prevent the terminals from deforming due to excessive force. The limit spring pushes the limit block into the limit groove of the extrusion block to achieve mechanical locking and ensure stable contact pressure. The electromagnetic block cooperates with the iron positioning plate to provide a magnetic attraction power structure, which can release the locking without additional external force, so that the push block automatically pushes the dual plug-in board body out of the slot.

[0010] Furthermore, limit rods are installed on both sides between the positioning plates, and a moving groove is formed between the slots, with the surface of the limit rods slidingly connected to the interior of the moving groove.

[0011] With the above scheme, the limiting rod slides in the moving groove, restricting the moving direction of the positioning plate and preventing it from tilting or shifting in the slot. At the same time, when the positioning plates are attracted by the electromagnetic block, the positioning plates move synchronously, ensuring that the pushing force of the pushing block is synchronized.

[0012] Furthermore, a synchronization block is installed between the pushing blocks, a buffer block is installed on the outside of the synchronization block, and an elastic block is installed on the outside of the pushing block.

[0013] The above scheme connects the push blocks on both sides with a synchronous long block, ensuring that the buffer springs on both sides are compressed and released synchronously during insertion and removal, so that the double plug-in board body is subjected to uniform force, avoiding tilting caused by force on one side. The buffer block and elastic block elastically buffer and reduce impact force, reduce local stress concentration, and protect the connector body and the double plug-in board body.

[0014] Furthermore, a micro switch is installed on the inner side of the inner wall of the buffer groove, and the micro switch is electrically connected to an LED light through a wire. The LED light is installed on the top of the dual-plug plate body.

[0015] With the above solution, when the dual plug-in board is plugged in, the push block triggers the micro switch and lights up the LED light, providing a visual indication to the user that the connection is complete. This avoids contact failure caused by improper plugging and improves the ease of operation and reliability.

[0016] Furthermore, the top of the dual-insertion plate body is provided with an installation groove, and a control button is installed on the inner wall of the installation groove. The control button is electrically connected to the electromagnetic block through a wire.

[0017] The above solution involves pressing the control button to activate the electromagnetic block circuit, causing it to generate a magnetic attraction to the positioning plate. This causes the limit block to disengage from the limit groove, releasing the jamming state and triggering the buffer spring to release potential energy, thus automatically popping out the dual-insertion board body. This allows users to easily disassemble the board and avoids damage to the terminals from forced insertion or removal.

[0018] Furthermore, a torsion spring is installed on one side of the inner wall of the mounting groove, a protective plate is installed on the other end of the torsion spring, and a movable block is installed on the top of the protective plate.

[0019] The above solution uses a torsion spring to automatically cover the control buttons with a protective plate, preventing accidental touches that could lead to erroneous locking. The movable block allows users to manually lift the protective plate and operate the control buttons, thus protecting the control function while ensuring ease of use.

[0020] Furthermore, the four sets of limiting springs are provided with positioning rods inside, the inner side of which can pass through the positioning plate and the limiting block in sequence, and the outer side of the positioning rod is installed with the inner side of the electromagnetic block.

[0021] With the above solution, the positioning rod passes through the positioning plate and the limiting block, providing linear motion guidance for them when the limiting spring is compressed and reset, avoiding the limiting block from shifting or shaking, ensuring that the limiting block is accurately embedded in the limiting groove when snapped together, and improving the reliability and durability of the mechanical connection.

[0022] Furthermore, the surface of the positioning plate slides inside the slot, the outer side of the limiting block away from the pushing block is inclined and chamfered, and the inner side of the squeezing block near the limiting block is inclined and chamfered.

[0023] The above solution creates a beveled contact during insertion, guiding the extrusion block to push the limit block and positioning plate to move smoothly, reducing frictional resistance and making the insertion process smoother. At the same time, it disperses contact stress and avoids wear or deformation of components caused by right-angle collisions.

[0024] Beneficial effects

[0025] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0026] I. This utility model provides a buffer groove, a buffer spring, a push block, and an electromagnetic block in the buffer ejection component. These components provide elastic buffering when the dual plug-in board body is inserted or removed from the connector body slot. The locking and limiting component can lock the dual plug-in board body into the connector body. At the same time, the locking and limiting component, together with the buffer ejection component, can automatically eject the dual plug-in board body from the connector body, effectively solving the problem of excessive or insufficient force during insertion and removal.

[0037] The buffer ejection assembly 4 includes a buffer groove 41. A buffer spring 42 is installed on the inner side of the inner wall of the buffer groove 41. There are four sets of buffer springs 42, which are equidistant from each other. A push block 43 is installed on the other end of the buffer spring 42. The buffer spring 42 provides elastic buffering when the dual insert plate body 2 is inserted or removed, and pushes the dual insert plate body 2 out of the slot 3 by pushing the push block 43. An electromagnetic block 44 is installed on the outer side of the inner wall of the slot 51. The electromagnetic block 44 generates a magnetic attraction to attract the positioning plate 53 after being energized, and drives the limiting block 54 to disengage from the limiting groove 56 to release the jamming. The other end of the limiting spring 52 is installed on the inner side of the electromagnetic block 44. The positioning plate 53 is made of iron and magnetically cooperates with the electromagnetic block 44. The electromagnetic block 44 is a prior art optional model: M ISUM I EMFC-6-50.

[0038] A micro switch 11 is installed on the inner side of the inner wall of the buffer groove 41. The micro switch 11 is electrically connected to an LED light 12 via a wire. The LED light 12 is installed on the top of the dual plug-in board body 2 and is used to trigger the light indicator when the dual plug-in board body 2 is fully plugged in.

[0039] The top of the dual-insertion plate body 2 is provided with a mounting groove 13. A control button 14 is installed on the inner wall of the mounting groove 13. The control button 14 is electrically connected to the electromagnetic block 44 through a wire and is used to trigger the electromagnetic block 44 to attract the positioning plate 53 to release the jamming. A torsion spring 15 is installed on one side of the inner wall of the mounting groove 13. A protective plate 16 is installed on the other end of the torsion spring 15. The torsion spring 15 is used to automatically reset the protective plate 16. The protective plate 16 is used to prevent the control button 14 from being accidentally touched.

The control button 14 is a prior art optional model C&K TS-1187A-BA.

[0040] Limiting rods 6 are installed on both sides between the positioning plates 53, and a moving groove 7 is opened between the slots 51. The surface of the limiting rod 6 is slidably connected to the inside of the moving groove 7. The limiting rod 6 restricts the moving direction of the positioning plates 53 and makes the positioning plates 53 move synchronously. Synchronous long blocks 8 are installed between the pushing blocks 43. The synchronous long blocks 8 can push the double insert plate body 2 synchronously under the push of the pushing blocks 43. A buffer block 9 is installed on the outside of the synchronous long blocks 8, and an elastic block 10 is installed on the outside of the pushing blocks 43. The buffer block 9 and the elastic block 10 are used to evenly disperse the impact force during the insertion and removal of the double insert plate body 2.

[0041] The four sets of limiting springs 52 are equipped with positioning rods 18 inside. The inner side of the positioning rods 18 can pass through the positioning plate 53 and the limiting block 54 in sequence. The outer side of the positioning rods 18 is installed with the inner side of the electromagnetic block 44 to guide the limiting block 54 and the positioning plate 53 to move in a straight line.

[0042] The surface of the positioning plate 53 slides inside the slot 51. The outer side of the limiting block 54 away from the pushing block 43 is set with an inclined chamfer, which can adapt to the pushing of the squeezing block 55 and make it move upward. The inner side of the squeezing block 55 near the limiting block 54 is set with an inclined chamfer, which can effectively cooperate with the inclined chamfer of the limiting block 54 to push the limiting block 54 to move upward.

[0043] Working principle: When the dual-insertion board body 2 is inserted into the slot 3 of the connector body 1, the dual-insertion board body 2 first pushes the pressing block 55 to move and contact the limiting block 54. Since the outer side of the limiting block 54 and the inner side of the pressing block 55 are both inclined chamfered, the insertion force of the pressing block 55 pushes the limiting block 54 and the positioning plate 53 to move outward of the slot 51 through the chamfered inclined surface. The moving positioning plate 53 pushes and compresses the limiting spring 52 and stores elastic potential energy. The pressing block 55 continues to move, causing the pushing block 43 to move. The pushing block 43 is forced to compress the buffer spring 42, causing the buffer spring 42 to compress and store potential energy. At the same time, the pushing block 43 can buffer a certain amount of pushing force to avoid damage caused by excessive local stress. As the dual-insertion board body 2 moves, the pressing block 55 continues to move, pushing the limiting block 54 and the positioning plate 53 to move outward of the slot 51. As the insertion continues, when the limiting groove 56 on the pressing block 55 moves directly below the limiting block 54, the limiting spring 52 releases its elastic potential energy, pushing the positioning plate 53 to reset, so that the limiting block 54 is precisely embedded in the limiting groove 56, forming a mechanical snap-fit. At this time, the four sets of equidistantly distributed limiting springs 52 provide uniform and continuous contact pressure, ensuring that the dual plug-in board body 2 and the connector body 1 fit tightly together, avoiding unstable contact resistance or contact failure under vibration environment due to insufficient force. When the dual plug-in board body 2 is inserted into place, the pushing block 43 triggers the micro switch 11 on the inner wall of the buffer groove 41, which lights up the LED light 12 on the top of the dual plug-in board body 2 through the wire, visually indicating to the user that the connection is complete, improving the ease of operation.

[0044] When disassembly is required, first lift the protective plate 16 on the mounting slot 13 by moving block 17, and reset it by torsion spring 15. Press control button 14 to activate electromagnetic block 44 on the outer side of inner wall of slot 51. Since the positioning plate 53 is made of iron, electromagnetic block 44 generates magnetic attraction after being energized, pulling positioning plate 53 to move outward of slot 51, causing limit block 54 to disengage from limit groove 56 of pressing block 55, thus releasing mechanical jamming.

[0045] As the limit block 54 unlocks, the buffer spring 42 releases its stored potential energy, pushing the push block 43 to move the dual plug-in board body 2 through the synchronous long block 8, so that it can be smoothly ejected from the slot 3. This avoids the user applying too much force and causing damage to the terminals, ensuring that the disassembly process is safe and controllable, and preventing the dual plug-in board body 2 from being damaged due to excessive force during insertion and removal.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
