Description

Technical Field

[0001] This utility model relates to the field of insertion and removal mechanism technology, and in particular discloses a PCB board gold finger snap-in insertion and removal mechanism. Background Technology

[0002] In electronic devices, reliable connection between PCB board and external connector is crucial. However, traditional gold finger plugging and unplugging methods have problems such as poor contact stability, inconvenient operation, easy wear, weak environmental adaptability and high maintenance costs. Therefore, the market urgently needs a PCB board gold finger snap-fit ​​plugging and unplugging mechanism that is anti-loosening, anti-reverse insertion, long life, easy to operate and can adapt to complex environments. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a PCB board gold finger snap-in and snap-out mechanism.

[0004] To achieve the above objectives, this utility model provides a PCB gold finger snap-fit ​​insertion and removal mechanism, comprising an insertion and removal body, a clamping component hinged to the insertion and removal body, and an elastic reset assembly for driving the clamping component to reset. The clamping component includes a first clamping plate, a second clamping plate, and a pressing clamping part connected to the first clamping plate and the second clamping plate. The first clamping plate and the second clamping plate are respectively disposed on both sides of the insertion and removal body. The insertion and removal body has multiple sets of insertion and removal ports. Pressing the pressing clamping part moves the first clamping plate and the second clamping plate away from the insertion and removal ports. After the external connector is inserted into the insertion and removal body through the insertion and removal port, the pressing clamping part is released to reset the first clamping plate and the second clamping plate. The first clamping plate and the second clamping plate clamp the external connector inserted into the insertion and removal port to prevent loosening.

[0005] This PCB board gold finger snap-fit ​​insertion and removal mechanism achieves convenient and stable connection operation through the coordinated design of the hinged clamping component and the insertion and removal body: During operation, the user presses the pressing end of the clamping component, causing the first and second clamping plates to open outward around the hinge point, providing space for the external connector to be inserted into the multiple sets of insertion and removal ports on the insertion and removal body; after releasing the press, the clamping plate automatically returns to its original position under the action of the elastic reset structure (such as torsion spring or elastic arm), and the anti-slip texture or snap-fit ​​structure on its inner wall tightly clamps the gold finger area of ​​the connector, effectively preventing poor contact caused by vibration or pulling; the multiple sets of insertion and removal ports are arranged in an array to adapt to different specifications of connectors, the one-handed pressing operation simplifies the process, the lever design of the hinged structure and clamping plate reduces the operating force required, and the compact layout saves installation space, significantly improving the maintenance efficiency and connection reliability of electronic equipment.

[0006] The plug-in / plug-out body is provided with a first hinge portion and a second hinge portion parallel to the first hinge portion, and both the first hinge portion and the second hinge portion are provided with a first rotating shaft.

[0007] The clamping plate includes a clamping plate surface and a connector disposed on the side of the clamping plate surface. The connector is provided with a first rotating slot, a second rotating slot, and a first groove. The first groove is disposed on the end face of the free end of the connector. The first clamping plate is rotatably disposed on the first rotating shaft of the first hinge part of the insertion and removal body via the first rotating slot. The second clamping plate is rotatably disposed on the first rotating shaft of the second hinge part of the insertion and removal body via the first rotating slot.

[0008] The pressing and clamping part is provided with a first clamping member and a second clamping member. The first clamping member includes a first handle and a third hinge portion disposed at one end of the first handle. The second clamping member includes a second handle and a fourth hinge portion disposed at one end of the second handle. Both the third hinge portion and the fourth hinge portion are provided with a second rotating shaft. The first clamping plate is rotatably disposed on the second rotating shaft of the first clamping member through a second rotating slot, and the second clamping plate is rotatably disposed on the second rotating shaft of the second clamping member through a second rotating slot.

[0009] The first clamping member has a first protrusion on the end face away from the first handle, and the second clamping member has a second protrusion on the end face away from the second handle; the first clamping member is engaged in the first groove of the first clamping plate via the first protrusion, and the second clamping member is engaged in the first groove of the second clamping plate via the second protrusion.

[0010] This PCB board gold finger snap-fit ​​insertion and removal mechanism achieves a highly efficient and stable connection solution through the collaborative design of multi-stage hinge transmission and elastic adaptive structure: The insertion and removal body adopts a double parallel hinge part with a double rotating shaft structure, so that the first and second clamping plates are independently hinged through the first rotating slot of the connector, forming a distributed force system; the third and fourth hinge parts of the pressing clamping part form a four-bar transmission mechanism through the second rotating shaft and the second rotating slot of the clamping plate. When the first and second handles are held, the snap-fit ​​structure of the protrusion and groove converts the pressing action into the outward movement of the clamping plate. After release, the elastic reset element (such as a torsion spring) drives the clamping plate to accurately return to its original position along the slot trajectory. The double rotating slot design allows the clamping surface to produce a small axial displacement to adaptively compensate for connector tolerances. The cooperation between the second rotating slot and the guide post of the insertion and removal body forms a double constraint, which significantly improves the clamping and positioning accuracy. This mechanism reduces the operating force requirement through a lever-type force-saving structure, and the modular hinge components facilitate quick disassembly and maintenance, making it particularly suitable for industrial scenarios with high-frequency insertion and removal and mixed assembly of multiple connector specifications.

[0011] The number of elastic reset components is multiple. The clamping plate surface is provided with a second groove, and the insertion and removal body is provided with a third groove. One end of the elastic reset component is accommodated in the second groove, and the other end is accommodated in the third groove.

[0012] Multiple sets of elastic reset components (such as springs or elastic rubber pillars) are embedded at both ends into the second groove of the clamping plate and the third groove of the insertion / removal body, forming a pre-compression assembly structure. When the clamping part is pressed, the elastic components are compressed and stored, and the clamping plate extends outward along the hinge axis to form an insertion channel. After release, the elastic potential energy drives the clamping plate to automatically reset. Its inner wall anti-slip structure tightly wraps the connector gold finger area. The limiting design of the second and third grooves prevents the elastic components from shifting and ensures that the clamping force is evenly distributed. The symmetrical layout of multiple sets of elastic components can effectively compensate for manufacturing tolerances and avoid stress concentration on one side. It is particularly suitable for anti-loosening scenarios under vibration conditions. At the same time, the modular elastic components facilitate quick replacement and maintenance, significantly improving the ease of operation and connection reliability of the insertion / removal mechanism.

[0013] The clamping plate has multiple sets of protrusions on the side near the insertion port, which are used to abut against the external connector.

[0014] This mechanism significantly improves connection stability and adaptability through a bump design on the clamping plate surface: multiple bump arrays are distributed in the contact area of ​​the clamping plate surface. When the clamping plate is reset, the bumps engage with the outer connector shell or gold finger edge in a multi-point contact manner. Their serrated or wavy surface structure effectively increases the coefficient of friction and prevents axial movement under vibration conditions. The bumps are made of conductive rubber or engineering plastic material, which ensures clamping force while avoiding scratching the connector surface. The adjustable bump layout (such as a stepped arrangement) can adapt to connectors of different thicknesses and achieves adaptive clamping through elastic deformation. When the insertion and removal body is subjected to tension, the mating structure of the bumps and the connector forms a mechanical locking effect. Combined with the continuous clamping force of the elastic reset component, a dual anti-loosening mechanism is constructed, which is particularly suitable for high reliability requirements such as automotive electronics or industrial control. At the same time, the modular design of the bumps facilitates quick replacement to match special specification connectors.

[0015] A hollow section is provided on the surface of the clamping plate.

[0016] Hollowed-out sections (such as honeycomb, square hole, or strip hole arrays) in key stress areas of the clamping plate can effectively reduce the overall weight of the mechanism. At the same time, removing redundant materials can improve heat dissipation efficiency and prevent heat accumulation caused by high-frequency plugging and unplugging.

[0017] The first and second handles are equipped with anti-slip parts.

[0018] The organization significantly improved operational reliability and user experience by setting anti-slip parts on the first and second handles: the anti-slip parts adopt knurled texture, diamond-shaped bumps or soft rubber coating, etc., and are distributed in the palm contact area of ​​the handle. Its surface friction coefficient is 3-5 times higher than that of ordinary smooth surfaces, effectively preventing slippage caused by sweaty hands, oil stains or vibration during operation.

[0019] The inner sidewall of the plug-in port is provided with a foolproof guide boss, and the insertion end of the external connector is provided with a structure that matches the foolproof guide boss. When the connector is inserted in reverse, the foolproof guide boss blocks the connector end face to prevent it from being inserted.

[0020] This mechanism significantly improves the reliability and operational safety of insertion through the anti-foolproof guide boss inside the insertion port and the connector end structure: the anti-foolproof guide boss adopts a wedge-shaped or inclined structure, forming a unique matching path with the pre-set notch at the connector insertion end. When the connector is inserted in the reverse direction, the end face of the boss and the flat end of the connector will mechanically interfere, using physical limits to prevent incorrect insertion and avoid bending of the gold fingers or damage to the pins; when inserted in the forward direction, the inclined surface of the boss and the connector guide groove form a sliding fit, realizing automatic centering guidance and reducing the difficulty of operation.

[0021] The beneficial effects of this utility model are as follows: This PCB board gold finger snap-fit ​​insertion and removal mechanism achieves efficient and reliable connection through the synergistic innovation of multi-level mechanical transmission and anti-loosening structure. When the handle is pressed, the vertical force is converted into the outward movement of the clamping plate through the cooperation of the rotating shaft and the slot. After release, the elastic reset component drives the clamping plate to accurately return to its original position along the trajectory of the double rotating slot. Combined with the mechanical engagement of the array of protrusions on the clamping surface and the friction enhancement of the anti-slip texture, a dual anti-loosening mechanism is constructed. The anti-foolproof guide protrusion of the insertion port and the connector end form a physical anti-foolproof structure to avoid damage from mis-insertion. The hollow design reduces weight and optimizes heat dissipation, and the anti-slip handle improves operational stability. This mechanism, through modular hinge components and adaptive clamping structure, takes into account both high-frequency insertion and removal durability and compatibility with multiple connector specifications, significantly improving the maintenance efficiency and connection reliability of electronic equipment.

[0038] The PCB board gold finger snap-fit ​​mechanism achieves a highly efficient and stable connection solution through the collaborative design of multi-stage hinge transmission and elastic adaptive structure: the snap-fit ​​body 1 adopts a double parallel hinge part with a double rotating shaft structure, so that the first and second clamping plates 4 are independently hinged through the first rotating slot 13 of the connector 12, forming a distributed force system; the third and fourth hinge parts 22 of the pressing clamping part 5 form a four-bar linkage transmission mechanism through the second rotating shaft 23 and the second rotating slot 14 of the clamping plate. When the first and second handles 21 are gripped, the protrusions and grooves... The snap-fit ​​structure converts the pressing action into the outward movement of the clamping plate. After release, the elastic reset element (such as a torsion spring) drives the clamping plate to return to its precise position along the slot track. The dual rotating slot design allows the clamping surface to produce a small axial displacement to adaptively compensate for connector tolerances.
