Description

Technical Field

[0001] This invention relates to the field of connector assembly technology, specifically to a connector assembly and electrical equipment. Background Technology

[0002] In the field of modern electrical equipment, connectors, as core components for circuit connection and signal transmission, are crucial to equipment performance and lifespan due to their assembly reliability and stability. As electrical equipment evolves towards miniaturization, integration, and high performance, the requirements for connector assembly structure and installation methods become increasingly stringent.

[0003] In traditional connector assembly methods, snap-fit ​​connections are quite common. Snap-fit ​​connections are further divided into easy-to-disassemble and difficult-to-disassemble types based on the difficulty of disassembly, each with its own advantages and disadvantages:

[0004] Easy-to-disassemble clips: Convenient disassembly facilitates equipment maintenance and component replacement, shortening repair time and improving efficiency. However, structural limitations result in weak connection strength, making them prone to loosening and detachment under external force during operation, affecting signal transmission and circuit stability. For example, mobile electronic devices may experience poor contact, system crashes, or data loss as a result. While the beveled sides facilitate removal, the small locking depth and limited contact area make it difficult to provide sufficient pressure. Furthermore, the flexible structure is soft and easily deformed under stress, failing to maintain a stable fit.

[0005] Difficult-to-remove clips: These offer high connection strength, providing a secure connection for the connector and resisting external interference, ensuring normal operation of the equipment in harsh environments. However, they are difficult to disassemble, requiring specialized tools, consuming time and effort, increasing maintenance costs, and potentially damaging components. They typically have a beveled side on one side and a right angle on the other (anti-reverse plane). When the right-angled side is inserted into the groove and parallel to the embedding surface, there is some space between the right-angled side and the embedding surface, which can cause relative displacement between the connector and components. Regardless of the type of clip, they are insufficient in ensuring a tight fit between the connector and components to improve sealing. Poor connector sealing allows dust, moisture, and other impurities to enter the equipment, corroding and damaging the connector and circuitry, reducing equipment reliability and lifespan. This is especially problematic in environmentally demanding equipment such as outdoor communication base stations, potentially causing malfunctions and affecting the normal operation of the communication network. Summary of the Invention

[0006] The technical solution of the present invention is to provide a connector assembly and electrical equipment, which not only ensures the high-strength connection between the mounting base and the printed circuit board and the stability of the equipment structure, but also facilitates the quick separation of the mounting panel and the printed circuit board for easy connector maintenance and replacement. At the same time, it improves the stability and sealing of the assembly after insertion, effectively prevents impurities from entering the equipment, and improves the reliability, maintainability and overall performance of the equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a connector assembly, comprising a printed circuit board, a mounting base, a connector, and a mounting panel;

[0008] The printed circuit board has multiple mounting slots arranged in a circular array;

[0009] The mounting base has a hard-to-remove buckle at the bottom, which includes a clearance surface and a backstop surface. The backstop surface is embedded into the mounting groove to connect the printed circuit board and the mounting base. The top of the mounting base has an assembly groove.

[0010] The connector is embedded into the mounting base through a mounting slot;

[0011] The mounting panel has an easy-release buckle at the bottom. The easy-release buckle includes a relief surface and a backstop bevel. The backstop bevel is inserted into the mounting groove to connect the mounting panel and the printed circuit board, and to define the position of the connector and the mounting base.

[0012] The protective sleeve is elastically slidably mounted on the mounting panel via an elastic element, and has an installation opening;

[0013] Limiting components are installed inside the protective sleeve;

[0014] When the connector is in use, the protective sleeve and the printed circuit board are relatively displaced. During this process, the limiting component is embedded between the hard-to-remove clip and the easy-to-remove clip. By squeezing the hard-to-remove clip and the easy-to-remove clip, the movement resistance of the hard-to-remove clip is increased. At the same time, the engagement amount of the easy-to-remove clip is increased, thereby improving its connection strength.

[0015] As a further aspect of the present invention, the difficult-to-remove buckle includes:

[0016] A short skew beam, wherein the short skew beam is elastic and fixed to the mounting base;

[0017] Anti-reverse component one, the anti-reverse component one is fixed at the end of the short skew beam, and is provided with a relief surface one and an anti-reverse plane connected end to end;

[0018] The anti-reverse component moves into the mounting slot, causing the positioning surface to abut against the side wall of the mounting slot, which deforms the short eccentric beam, making it easier for the anti-reverse component to cross the mounting slot and realize the assembly of the mounting base and the printed circuit board.

[0019] As a further aspect of the present invention, the easy-to-remove buckle includes:

[0020] A long, skewed beam with inclined and elastic sidewalls is fixed to a mounting panel.

[0021] The second anti-reverse component is fixed at the end of the long skew beam and is provided with a two-way relief surface and an anti-reverse inclined surface connected end to end.

[0022] The second anti-reverse component moves into the mounting slot, causing the second positioning surface to abut against the side wall of the mounting slot, which deforms the long eccentric beam, making it easier for the second anti-reverse component to cross the mounting slot and realize the assembly of the mounting panel and the printed circuit board.

[0023] As a further embodiment of the present invention, the limiting component includes a sliding sleeve fixed inside the protective sleeve, the sliding sleeve being slidably provided with a pressing block, the sidewall of the pressing block being inclined and able to be embedded between a difficult-to-remove buckle and an easy-to-remove buckle; a time-delay spring is fixed between the pressing block and the sliding sleeve; when the connector is pulled out, the spring force is released by the time-delay spring to delay the movement time of the pressing block.

[0024] As a further embodiment of the present invention, an auxiliary sleeve is slidably provided on the side wall of the mounting base, and a wedge block is fixedly provided on the side wall of the short skew beam. The auxiliary sleeve can move along the mounting base and deform the short skew beam by squeezing the wedge block, thereby disengaging the anti-reverse component from the mounting groove. An inclined elastic bracket is installed between the auxiliary sleeve and the mounting base, and the elastic bracket is used for resetting the auxiliary sleeve.

[0025] As a further aspect of the present invention, a dustproof structure is installed at the end of the protective sleeve, the dustproof structure comprising:

[0026] The plugs are arranged in a circular array and are elastically slidable with the protective sleeve via spring plates; the plugs together can seal the installation port.

[0027] The trigger element is inclined and elastic, and is fixed to the plug. After the part that mates with the connector contacts the trigger element, the inclined trigger element drives the plug to move in all directions, exposing the installation port.

[0028] As a further embodiment of the present invention, the connector is fixedly provided with a rectangular plate that matches the assembly groove, the inner side of the mounting base is fixedly provided with an annular buckle, and the side wall of the connector is provided with a groove that cooperates with the annular buckle.

[0029] As a further embodiment of the present invention, the mounting base is fixedly provided with a circumferential buckle, and the mounting panel is provided with a through hole that cooperates with the circumferential buckle; a cone is fixedly provided on the inner side of the protective sleeve, and the cone is coaxially arranged with the circumferential buckle.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. Regarding the connection between the mounting base and the printed circuit board (PCB), a difficult-to-remove snap-fit ​​is used. Although the structural characteristics of the snap-fit's anti-reverse surface and the anti-reverse element (in this embodiment, the PCB) result in an initial gap, this connection method provides extremely high connection strength, effectively preventing the mounting base and PCB from being forcefully pulled apart, preventing damage to the PCB, and ensuring the stability of the equipment structure. The mounting panel and PCB are connected using an easy-to-remove snap-fit. Because the easy-to-remove snap-fit ​​has a small engagement amount, the two can be easily separated, greatly facilitating the removal, replacement, or repair of the connector. This is especially suitable for replacement operations after excessive wear from long-term insertion and removal of the connector, improving the maintainability of the equipment.

[0032] 2. When the protective sleeve stops moving upon contact with the outer contour of the insertion position, while other components continue to move, the elastic element is compressed, and the limiting component moves closer to the printed circuit board, squeezing the difficult-to-remove and easy-to-remove clips. This not only increases the resistance to the movement of the difficult-to-remove clips, reducing the risk of relative movement between the mounting base and the printed circuit board, but also increases the engagement depth of the easy-to-remove clips, improving the connection strength between the mounting panel and the printed circuit board. This keeps the distance between the mounting panel and the printed circuit board relatively fixed, thereby ensuring the relative position stability of the mounting base and the connector. Ultimately, while completing the connector assembly insertion, it ensures the stability and reliability of the entire assembly after insertion, improving the overall performance of the equipment. During the insertion process, the printed circuit board is subjected to thrust, which is sequentially transmitted to the mounting base, connector, and mounting panel. After the printed circuit board is fixed to the insertion body, the various components are in a tight fit during insertion, ensuring a sealed state during use. This prevents dust, moisture, and other impurities from entering the equipment, corroding and damaging the connector and circuitry, and reducing the reliability and service life of the equipment.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Easy-to-remove clips: Clip connections that can be removed without tools.

[0048] Difficult-to-remove clips: Clip connections that require tools to remove.

[0049] Please see Figure 1-11The present invention provides a technical solution: a connector assembly, comprising a printed circuit board 1, a mounting base 2, a connector 4, and a mounting panel 5.

[0050] The printed circuit board 1 has multiple mounting slots 11 arranged in a circular array;

[0051] Mounting base 2 has a hard-to-remove buckle 3 installed at the bottom. The hard-to-remove buckle 3 includes a clearance surface 33 and a backstop surface 34, and is embedded in the mounting groove 11 through the backstop surface 34 to connect the printed circuit board 1 and the mounting base 2. The top of the mounting base 2 has an assembly groove 21.

[0052] Connector 4 is embedded in mounting base 2 through assembly slot 21;

[0053] The mounting panel 5 has an easy-release buckle 6 installed at the bottom. The easy-release buckle 6 includes a relief surface 63 and a backstop slope 64. The backstop slope 64 is embedded in the mounting groove 11 to connect the mounting panel 5 and the printed circuit board 1, and to limit the position of the connector 4 and the mounting base 2.

[0054] The protective sleeve 7 is elastically slidably mounted on the mounting panel 5 via the elastic element 71, and has an installation opening 75.

[0055] Limiting component 8 is installed inside protective sleeve 7;

[0056] When the connector 4 is in use, the protective sleeve 7 and the printed circuit board 1 are relatively displaced, so that the limiting component 8 is embedded between the hard-to-remove buckle 3 and the easy-to-remove buckle 6; by squeezing the hard-to-remove buckle 3 and the easy-to-remove buckle 6, the moving resistance of the hard-to-remove buckle 3 is increased, and the engagement amount of the easy-to-remove buckle 6 is increased, thereby improving its connection strength.

[0057] When assembling the mounting base 2, align the hard-to-remove buckle 3 with the mounting slot 11 on the printed circuit board 1 and insert it into it to complete the assembly between the mounting base 2 and the printed circuit board 1; due to the gap between the hard-to-remove buckle 3 and the buckle position, there is a slight gap between the mounting base 2 and the printed circuit board 1, and the two can still move relative to each other.

[0058] The cause of the gap: See Figure 11 The anti-reverse surface of the difficult-to-remove buckle 3 is flat. During insertion, the deflection beam deflects, causing the outer end of the anti-reverse surface to change position and become parallel to the anti-reverse component and its adjacent end face. When the anti-reverse surface passes the anti-reverse component, the deflection beam deflects from the inclined state to the vertical state until the anti-reverse surface is parallel to the bottom of the anti-reverse component. The bottom of the deflection beam in the vertical state will be lower than the bottom of the anti-reverse component, that is, the distance from the deflection beam to the anti-reverse surface is greater than the distance L from the top of the difficult-to-remove buckle 3 to the bottom of the anti-reverse component, which causes the difficult-to-remove buckle 3 and the anti-reverse component to be able to move relative to each other. In this embodiment, the anti-reverse component is the printed circuit board 1.

[0059] The reason for using a difficult-to-remove clip 3 between the mounting base 2 and the printed circuit board 1 is that the connection strength between the mounting base 2 and the printed circuit board 1 is high, which can prevent the mounting base 2 and the printed circuit board 1 from being pulled apart by force, thus preventing damage to the printed circuit board 1.

[0060] When assembling connector 4, connector 4 is inserted into mounting base 2 through assembly slot 21, and assembly slot 21 initially limits the position of connector 4.

[0061] When assembling the mounting panel 5, align the easy-release buckle 6 with the mounting slot 11 on the printed circuit board 1 and insert it to complete the assembly between the mounting panel 5 and the printed circuit board 1. Since the easy-release buckle 6 has a small engagement amount, the mounting panel 5 and the printed circuit board 1 can be easily separated, making it convenient to remove the connector 4 for replacement or repair. This is suitable for connector 4 to be replaced after long-term plugging and unplugging and excessive wear.

[0062] In use, align the mounting port 75 on the protective sleeve 7 with the insertion position and insert it. When the protective sleeve 7 touches the outer contour of the insertion position, the protective sleeve 7 stops moving, while the printed circuit board 1, mounting base 2, connector 4, and mounting panel 5 continue to move. The elastic element 71 is compressed. At the same time, the limiting component 8 moves closer to the printed circuit board 1. The limiting component 8 pushes out and squeezes the difficult-to-remove buckle 3 and the easy-to-remove buckle 6, increasing the resistance to the movement of the difficult-to-remove buckle 3, increasing the connection stability between the mounting base 2 and the printed circuit board 1, and reducing relative movement. At the same time, it increases the amount of insertion of the easy-to-remove buckle 6, increasing the connection strength between the mounting panel 5 and the printed circuit board 1. The distance between the mounting panel 5 and the printed circuit board 1 is relatively fixed, and the mounting base 2 and connector 4 between the mounting panel 5 and the printed circuit board 1 are also relatively fixed. After the insertion is completed, fix the printed circuit board 1 and the insertion body to complete the insertion of the connector assembly.

[0063] In summary, the connection between the mounting base 2 and the printed circuit board 1 utilizes a difficult-to-remove clip 3. Although the structural characteristics of the anti-reverse surface of the difficult-to-remove clip 3 and the anti-reverse element (the anti-reverse element is the printed circuit board 1 in this embodiment) result in an initial gap, this connection method provides extremely high connection strength, effectively preventing the mounting base 2 and the printed circuit board 1 from being pulled apart by excessive force, preventing damage to the printed circuit board 1, and ensuring the stability of the equipment structure. The mounting panel 5 and the printed circuit board 1 are connected using an easy-to-remove clip 6. Because the easy-to-remove clip 6 has a small engagement amount, the two can be easily separated, greatly facilitating the removal, replacement, or maintenance of the connector 4. This is especially suitable for replacement operations after the connector 4 has undergone excessive wear from long-term insertion and removal, improving the maintainability of the equipment.

[0064] During use, when the protective sleeve 7 stops moving against the outer contour of the insertion position while other components continue to move, the elastic element 71 is compressed, and the limiting component 8 moves closer to the printed circuit board 1 and squeezes the hard-to-remove clip 3 and the easy-to-remove clip 6. This not only increases the resistance to the movement of the hard-to-remove clip 3 and reduces the risk of relative movement between the mounting base 2 and the printed circuit board 1, but also increases the snapping amount of the easy-to-remove clip 6, improving the connection strength between the mounting panel 5 and the printed circuit board 1, making the distance between the mounting panel 5 and the printed circuit board 1 relatively fixed, thereby ensuring the relative position stability of the mounting base 2 and the connector 4. Finally, while completing the insertion of the connector assembly, it ensures the stability and reliability of the entire assembly after insertion, improving the overall performance of the equipment.

[0065] In addition, during the insertion process, the printed circuit board 1 is pushed and the force is transmitted to the mounting base 2, connector 4 and mounting panel 5 in sequence. After the printed circuit board 1 is fixed with the plug body, the various components are in a tight fit when plugged in, ensuring that they are in a sealed state during use. This can prevent dust, moisture and other impurities from entering the equipment, corroding and damaging the connector and circuit, and reducing the reliability and service life of the equipment.

[0066] As a further aspect of the present invention, the difficult-to-remove buckle 3 includes:

[0067] The short skew beam 31 is elastic and fixed to the mounting base 2;

[0068] Anti-reverse component 32 is fixed at the end of the short skew beam 31 and is provided with a relief surface 33 and an anti-reverse plane 34 connected end to end.

[0069] The anti-reverse component 32 moves into the mounting groove 11, causing the positioning surface 33 to abut against the side wall of the mounting groove 11, which deforms the short eccentric beam 31, making it easier for the anti-reverse component 32 to cross the mounting groove 11 and realize the assembly of the mounting base 2 and the printed circuit board 1.

[0070] Combination Figures 2-5 As shown, during the assembly of the mounting base 2 and the printed circuit board 1, the anti-reverse component 32 needs to be aligned with the mounting groove 11 and inserted. When the clearance surface 33 of the anti-reverse component 32 contacts the side wall of the mounting groove 11, the anti-reverse component 32 will deflect, which will cause the short skew beam 31 to bend and accumulate elastic potential energy. The deflection process causes the anti-reverse component 32 to be misaligned with the side wall of the mounting groove 11, creating conditions for subsequent insertion. After the anti-reverse component 32 passes the mounting groove 11, the elastic force accumulated by the short skew beam 31 is released, restoring it to a vertical state and causing the anti-reverse component 32 to partially overlap with the side wall of the mounting groove 11. At this time, the anti-reverse plane 34 of the anti-reverse component 32 can effectively restrict the reverse movement of the anti-reverse component 32, thereby successfully completing the assembly of the mounting base 2 and the printed circuit board 1.

[0071] From a mechanical perspective, when the skew beam deflects at the same angle, the shorter the skew beam, the greater the force required to pull it out or insert it. Therefore, this design employs a short skew beam 31 between the mounting base 2 and the printed circuit board 1. This design further increases the difficulty of separating the mounting base 2 from the printed circuit board 1, effectively improving the stability of the connection between them.

[0072] As a further aspect of the present invention, the easy-to-remove buckle 6 includes:

[0073] The long eccentric beam 61 has an inclined sidewall and is elastic. The long eccentric beam 61 is fixed to the mounting panel 5.

[0074] Anti-reverse component 2 62 is fixed at the end of the long eccentric beam 61 and is provided with a relief surface 2 63 and an anti-reverse inclined surface 64 connected end to end.

[0075] The second anti-reverse component 62 moves into the mounting groove 11, causing the second positioning surface 63 to abut against the side wall of the mounting groove 11, which deforms the long eccentric beam 61, making it easier for the second anti-reverse component 62 to cross the mounting groove 11 and realize the assembly of the mounting panel 5 and the printed circuit board 1.

[0076] Combination Figures 2-4 and Figure 6 As shown, during the assembly of the mounting panel 5 and the printed circuit board 1, the anti-reverse component 62 needs to be aligned with the mounting groove 11 and inserted. When the clearance surface 63 of the anti-reverse component 62 contacts the side wall of the mounting groove 11, the anti-reverse component 62 will deflect, causing the long inclined beam 61 to bend and accumulate elastic potential energy. This deflection action causes the anti-reverse component 62 to be misaligned with the side wall of the mounting groove 11, creating conditions for the subsequent insertion action. After the anti-reverse component 62 passes the mounting groove 11, the elastic force accumulated by the long inclined beam 61 is released, returning to a vertical state, and causing the anti-reverse component 62 to partially overlap with the side wall of the mounting groove 11. At this time, the anti-reverse inclined surface 64 of the anti-reverse component 62 can restrict the reverse movement of the anti-reverse component 62, thereby successfully completing the assembly of the mounting panel 5 and the printed circuit board 1.

[0077] Because the anti-reverse ramp 64 is inclined, when an external force is applied to try to pull out the anti-reverse member 62, the resistance borne by the mounting groove 11 is relatively small. This makes it easy to pull the mounting panel 5 out of the printed circuit board 1, which greatly facilitates the removal, replacement or maintenance of the connector 4.

[0078] Furthermore, when the inclined anti-reverse slope 64 presses against the side wall of the mounting groove 11, according to the principle of force interaction, the mounting groove 11 will exert a downward force on the anti-reverse slope 64 (such as...). Figure 10(Indicated direction). The anti-reverse ramp 64 transmits the force to the mounting panel 5. After the connector assembly is plugged in, the force causes the mounting panel 5 to continue moving toward the printed circuit board 1, thereby ensuring that the components of the connector assembly fit tightly together and effectively improving the sealing performance of the entire assembly.

[0079] As a further embodiment of the present invention, the limiting component 8 includes a sliding sleeve 81 fixed inside the protective sleeve 7, and a pressing block 82 is slidably disposed on the sliding sleeve 81. The side wall of the pressing block 82 is inclined and can be embedded between the difficult-to-remove buckle 3 and the easy-to-remove buckle 6. A time-delay spring 83 is fixed between the pressing block 82 and the sliding sleeve 81. When the connector 4 is pulled out, the spring force is released by the time-delay spring 83, which delays the time for the pressing block 82 to move.

[0080] See Figures 2-4 as well as Figure 7 During the movement of the protective sleeve 7 relative to the printed circuit board 1, the sliding sleeve 81, with the aid of the time-delay spring 83, drives the pressing block 82 to move towards the printed circuit board 1. When the pressing block 82 contacts the hard-to-remove clip 3 and the easy-to-remove clip 6, the time-delay spring 83 is compressed. At the same time, the pressing block 82 applies a pressing force to the hard-to-remove clip 3 and the easy-to-remove clip 6, causing the hard-to-remove clip 3 and the easy-to-remove clip 6 to press against the side wall of the mounting groove 11, and the pressing force gradually increases as the sliding sleeve 81 descends a greater distance.

[0081] When the connector assembly needs to be removed, the protective sleeve 7 moves relative to the printed circuit board 1 under the action of the elastic element 71, and the sliding sleeve 81 moves accordingly. At this time, the pressing block 82 is engaged between the hard-to-remove clip 3 and the easy-to-remove clip 6, and the time-delay spring 83 rebounds to compensate for the displacement. When the sliding sleeve 81 overcomes the resistance of the hard-to-remove clip 3 and the easy-to-remove clip 6 to the pressing block 82 through the tension applied by the time-delay spring 83, the pressing block 82 disengages from the hard-to-remove clip 3 and the easy-to-remove clip 6. This allows the hard-to-remove clip 3 and the easy-to-remove clip 6 to return to their normal state. When the connector is not in use, the easy-to-remove clip 6 can be easily removed, thus facilitating the replacement of the connector.

[0082] It is worth noting that during the connector assembly pull-out process, the clamping block 82 does not immediately disengage from the hard-to-remove clip 3 and the easy-to-remove clip 6. This design ensures that sufficient resistance is maintained between the mounting panel 5 and the mounting base 2 in the initial stage of the pull-out process, effectively preventing the assembly from disintegrating during the pull-out process and ensuring the stability and safety of the entire operation.

[0083] As a further embodiment of the present invention, an auxiliary sleeve 9 is slidably provided on the side wall of the mounting base 2, and a wedge block 91 is fixedly provided on the side wall of the short oblique beam 31. The auxiliary sleeve 9 can move along the mounting base 2 and deform the short oblique beam 31 by squeezing the wedge block 91, thereby disengaging the anti-reverse component 32 from the mounting groove 11. An inclined elastic bracket 92 is installed between the auxiliary sleeve 9 and the mounting base 2. The elastic bracket 92 is used for resetting the auxiliary sleeve 9.

[0084] When it is necessary to remove the mounting base 2 from the printed circuit board 1, the operator needs to move the auxiliary sleeve 9 towards the printed circuit board 1. During this process, the auxiliary sleeve 9 applies a squeezing force to the wedge block 91, which in turn squeezes the short eccentric beam 31, causing the short eccentric beam 31 to deform. As the short eccentric beam 31 deforms, the anti-reverse component 32 disengages from the mounting groove 11. This design is particularly suitable for situations where multiple difficult-to-remove clips 3 disengage simultaneously, effectively reducing the difficulty of disassembling the mounting base 2 and improving disassembly efficiency.

[0085] While the auxiliary sleeve 9 is moved toward the printed circuit board 1, the elastic bracket 92 deforms and accumulates elastic potential energy due to the external force. After the mounting base 2 is successfully removed, the operator releases the auxiliary sleeve 9, and the elastic bracket 92 releases the accumulated elastic potential energy, causing the auxiliary sleeve 9 to automatically return to its initial position, preparing for the next disassembly.

[0086] As a further embodiment of the present invention, a dustproof structure is installed at the end of the protective sleeve 7, the dustproof structure comprising:

[0087] The plugs 72 are arranged in a circular array and are elastically slidably set with the protective sleeve 7 via spring plates 73; the plugs 72 can jointly seal the installation port 75;

[0088] The trigger element 74, tilted and elastic, is fixed to the plug 72. When the part mating with the connector 4 contacts the trigger element 74, the tilted trigger element 74 drives the plug 72 to move outwards, exposing the mounting opening 75. When the connector assembly is pulled out, the spring plate 73, due to its elastic properties, returns the plug 72 to its initial position. At this time, the mounting opening 75 returns to a closed state. In this state, the mounting opening 75 is tightly closed, effectively preventing dust, moisture, and other external contaminants from entering the connector assembly, thereby avoiding these contaminants from adversely affecting the performance of the connector assembly and ensuring the stability and reliability of the connector assembly during subsequent use.

[0089] As a further aspect of the present invention, the connector 4 is fixedly provided with a rectangular plate 41 that matches the assembly slot 21, and an annular buckle 22 is fixedly provided on the inner side of the mounting base 2. A slot 42 that mates with the annular buckle 22 is provided on the side wall of the connector 4. The slot 42 and the annular buckle 22 engage with each other, providing initial positioning for the connector 4. Before the mounting panel 5 is fully installed, this engagement structure provides initial positioning for the connector 4, effectively preventing it from accidentally falling off due to external forces. Simultaneously, the rectangular plate 41 restricts the rotation of the connector 4, preventing it from rotating during operation and causing bending or deformation of the pins inserted into the printed circuit board 1. As a further aspect of the present invention, the mounting base 2 is fixedly provided with a circumferential buckle 23, and the mounting panel 5 has a through hole that mates with the circumferential buckle 23; a cone 24 is fixedly provided inside the protective sleeve 7, and the cone 24 is coaxially arranged with the circumferential buckle 23; the circumferential buckle 23 and the through hole cooperate with each other to realize the assembly of the mounting base 2 and the mounting panel 5, and further limit the connector 4 located therein, thereby effectively improving the stability of the connector 4 in use. When the protective sleeve 7 moves toward the mounting base 2, the cone 24 moves synchronously and enters the interior of the circumferential buckle 23. During the movement, the cone 24 applies a squeezing force to the top of the circumferential buckle 23, causing the outer diameter of the top circumferential buckle 23 to increase. This change not only makes the fit between the circumferential buckle 23 and the through hole tighter, but also applies a thrust to the mounting panel 5 pointing toward the mounting base 2, further improving the stability of the connector 4 in use.
