Description

Technical Field

[0001] The present invention relates to the technical field of connector assemblies, in particular to a connector assembly and electrical equipment. Background Art

[0002] In modern electrical equipment, connectors are core components for circuit connection and signal transmission. Their assembly reliability and stability are crucial to equipment performance and lifespan. As electrical equipment evolves toward miniaturization, integration, and higher performance, the requirements for connector assembly structure and installation methods are becoming more stringent.

[0003] Among traditional connector assembly methods, snap-on connections are more common. Snap-on connections are divided into easy-to-disassemble and difficult-to-disassemble types based on the difficulty of disassembly, each with its own advantages and disadvantages: Easy-to-remove clips: These fasteners are easily disassembled, facilitating equipment maintenance and component replacement, shortening repair time and improving efficiency. However, structural limitations result in weak connection strength, making them susceptible to loosening and falling apart under external forces during operation, impacting signal transmission and circuit stability. This can lead to poor contact, freezing, and data loss in mobile electronic devices. Slanted surfaces on both sides facilitate removal, but the small engagement and limited contact area make it difficult to provide sufficient pressure. Furthermore, the flexible structure is easily deformed under stress, making it difficult to maintain a stable fit.

[0004] Difficult-to-remove clips: They offer a strong connection, providing a secure connection and resistance to external interference, ensuring proper operation in harsh environments. However, they are difficult to remove, requiring specialized tools, time-consuming and labor-intensive, increasing repair costs, and potentially damaging components. They typically feature an angled surface on one side and a right-angled, non-returnable surface on the other. When the right-angled surface is inserted into the slot and aligned parallel to the insertion surface, some space exists between the right-angled surface and the insertion surface, which can cause relative displacement between the connector and the component.

[0005] Regardless of the type of snap, all have shortcomings in ensuring a tight fit between the connector and the components to improve sealing. Poor connector sealing allows impurities such as dust and moisture to enter the equipment, corroding and damaging the connector and circuitry, reducing equipment reliability and service life. This is especially true in environmentally sensitive equipment such as outdoor communication base stations, where failures can occur and affect 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 a high-strength connection between the mounting base and the printed circuit board and the stability of the equipment structure, but also facilitates the rapid separation of the mounting panel and the printed circuit board to facilitate the maintenance and replacement of the connector, while improving the stability and sealing of the assembly after insertion, effectively preventing impurities from entering the equipment, and improving the reliability, maintainability and overall performance of the equipment.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a connector assembly and electrical equipment, comprising a printed circuit board, a mounting seat, a connector, and a mounting panel; The printed circuit board is provided with a plurality of mounting slots arranged in a circumferential array; The mounting seat has a hard-to-remove buckle installed at the bottom, the hard-to-remove buckle includes a first relief surface and a non-return surface, and is embedded in the mounting groove through the non-return surface to connect the printed circuit board and the mounting seat; the top of the mounting seat is provided with an assembly groove; The connector is embedded in the mounting seat through the assembly groove; The mounting panel has an easily removable buckle installed at the bottom. The easily removable buckle includes a second relief surface and a non-return bevel. The non-return bevel is embedded in the mounting groove to connect the mounting panel and the printed circuit board, thereby limiting the position of the connector and the mounting seat. The protective cover is elastically slidably arranged on the installation panel through an elastic member and is provided with an installation opening; The limiting component is installed in the protective cover; When the connector is in use, the protective cover and the printed circuit board produce relative displacement. During this process, the limit component is embedded between the difficult-to-remove buckle and the easy-to-remove buckle; by squeezing the difficult-to-remove buckle and the easy-to-remove buckle, the movement resistance of the difficult-to-remove buckle is increased, and at the same time, the fastening amount of the easy-to-remove buckle is increased to improve its connection strength.

[0008] As a further solution of the present invention, the difficult-to-remove buckle includes: A short deflection beam, wherein the short deflection beam is elastic and fixed to the mounting seat; A first anti-return member, which is fixedly mounted at the end of the short deflection beam and is provided with a first yielding surface and an anti-return plane connected end to end; The anti-return component moves into the installation groove, allowing the positioning surface to contact the side wall of the installation groove, so that the short deflection beam is deformed, which makes it easier for the anti-return component to cross the installation groove and realize the assembly of the mounting seat and the printed circuit board.

[0009] As a further solution of the present invention, the easily detachable buckle includes: A long deflecting beam, the side wall of which is inclined and elastic, and the long deflecting beam is fixed to the mounting panel; The second anti-return component is fixedly arranged at the end of the long deflection beam and is provided with a second yielding surface and an anti-return inclined surface connected end to end; The second anti-return member moves into the installation groove, allowing the second positioning surface to contact the side wall of the installation groove, so that the long deflection beam is deformed, making it easier for the second anti-return member to cross the installation groove and realize the assembly of the installation panel and the printed circuit board.

[0010] As a further solution of the present invention, the limiting assembly includes a sliding sleeve fixed in the protective sleeve, and the sliding sleeve is slidably provided with an extrusion block, the side wall of the extrusion block is inclined and can be embedded between the difficult-to-remove buckle and the easy-to-remove buckle; a delay spring is fixed between the extrusion block and the sliding sleeve; when the connector is pulled out, the elastic force is released by the delay spring, delaying the movement time of the extrusion block.

[0011] As a further solution of the present invention, an auxiliary sleeve is slidingly provided on the side wall of the mounting seat, and a wedge block is fixed on the side wall of the short deflected beam. The auxiliary sleeve can move along the mounting seat and squeeze the wedge block to deform the short deflected beam and disengage the anti-return piece from the mounting groove; an elastic bracket is installed with an inclined arrangement between the auxiliary sleeve and the mounting seat, and the elastic bracket is used to reset the auxiliary sleeve.

[0012] As a further solution of the present invention, a dustproof structure is installed at the end of the protective sleeve, and the dustproof structure includes: The plugs are arranged in a circular array and elastically slide with the protective sleeve via spring sheets; the plugs can together seal the installation opening; The triggering member is tilted and elastic, and is fixed on the plug. After the part docking with the connector contacts the triggering member, the tilted triggering member drives the plug to move around to expose the installation port.

[0013] As a further solution of the present invention, the connector is fixed with a rectangular plate matching the assembly groove, the inner side of the mounting seat is fixed with an annular buckle, and the side wall of the connector is provided with a slot matching the annular buckle.

[0014] As a further solution of the present invention, the mounting seat is fixed with a circumferential buckle, and the mounting panel is provided with a through hole that cooperates with the circumferential buckle; a cone is fixed on the inner side of the protective sleeve, and the cone is coaxially arranged with the circumferential buckle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: A difficult-to-remove clip is used to connect the mounting base to the printed circuit board. Although a certain gap exists initially due to the structural characteristics of the difficult-to-remove clip's anti-return surface and anti-return member, this connection method provides extremely high connection strength, effectively preventing the mounting base and printed circuit board from being forcibly pulled apart, preventing damage to the printed circuit board and ensuring the stability of the device structure. The mounting panel and printed circuit board are connected using an easy-to-remove clip. Due to the small engagement of the easy-to-remove clip, the two can be easily separated, greatly facilitating connector removal, replacement, or repair. It is particularly suitable for replacement of connectors that have been excessively worn due to long-term plug-in and plug-in assembly, thus improving the maintainability of the device.

[0016] When the protective cover stops moving when it hits the outer contour of the plug-in position, while other components continue to move, the elastic part is compressed, the limit assembly approaches the printed circuit board and squeezes the difficult-to-remove buckles and the easy-to-remove buckles; it not only increases the resistance to the movement of the difficult-to-remove buckles, reduces the risk of relative movement between the mounting seat and the printed circuit board, but also increases the buckling amount of the easy-to-remove buckles, improves the connection strength between the mounting panel and the printed circuit board, and makes the distance between the mounting panel and the printed circuit board relatively fixed, thereby ensuring the relative position stability of the mounting seat and the connector, and finally completing the plug-in of the connector assembly while ensuring the stability and reliability of the entire assembly after plug-in, thereby improving the overall performance of the equipment.

[0017] During the plug-in process, the printed circuit board is subjected to thrust and is transmitted to the mounting seat, connector and mounting panel in turn. After the printed circuit board and the plug-in body are fixed, 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.

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.

[0021] Easy-to-detach snap fastener: a snap fastener connection that can be removed without tools.

[0022] Difficult-to-remove buckles: Buckle connections that require tools to remove.

[0023] See also Figure 1-11 The present invention provides a technical solution: a connector assembly and electrical equipment, including a printed circuit board 1, a mounting seat 2, a connector 4 and a mounting panel 5: The printed circuit board 1 is provided with a plurality of mounting slots 11 arranged in a circumferential array; The mounting base 2 has a hard-to-remove buckle 3 installed at the bottom. The hard-to-remove buckle 3 includes a relief surface 33 and a non-return surface 34. The non-return surface 34 is embedded in the mounting groove 11 to connect the printed circuit board 1 and the mounting base 2. The top of the mounting base 2 is provided with an assembly groove 21. The connector 4 is embedded in the mounting base 2 through the assembly groove 21; The mounting panel 5 has an easily removable buckle 6 installed at the bottom. The easily removable buckle 6 includes a second clearance surface 63 and a non-return bevel 64. The non-return bevel 64 is inserted into the mounting groove 11 to connect the mounting panel 5 and the printed circuit board 1, thereby defining the position of the connector 4 and the mounting seat 2. The protective cover 7 is elastically slidably mounted on the mounting panel 5 via an elastic member 71 and is provided with a mounting opening 75; The limiting component 8 is installed in the protective cover 7; When the connector 4 is in use, the protective cover 7 and the printed circuit board 1 are relatively displaced, so that the limit assembly 8 is embedded between the difficult-to-remove buckle 3 and the easy-to-remove buckle 6. By squeezing the difficult-to-remove buckle 3 and the easy-to-remove buckle 6, the movement resistance of the difficult-to-remove buckle 3 is increased, and the fastening amount of the easy-to-remove buckle 6 is increased, thereby improving the connection strength. When assembling the mounting base 2, align the difficult-to-remove buckle 3 with the mounting groove 11 on the printed circuit board 1 and insert it therein to complete the assembly between the mounting base 2 and the printed circuit board 1. Due to the gap between the difficult-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. Causes of gaps: See Figure 11 The anti-return surface of the difficult-to-remove buckle 3 is a plane. During the insertion process, the deflection beam deflects so that the outer end of the anti-return surface changes to be parallel to the anti-return piece and its adjacent end surface. When the anti-return surface passes over the anti-return piece, the deflection beam deflects from the inclined state to the vertical state until the anti-return surface is parallel to the bottom of the anti-return piece. The bottom of the deflection beam in the vertical state will be lower than the bottom of the anti-return piece, that is, the distance from the deflection beam to the anti-return surface is greater than the distance L from the top of the difficult-to-remove buckle 3 to the bottom of the anti-return piece, resulting in relative displacement between the difficult-to-remove buckle 3 and the anti-return piece; in this embodiment, the anti-return piece is the printed circuit board 1; The reason why the hard-to-remove buckle 3 is used 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 with great force, thereby preventing the printed circuit board 1 from being damaged. When assembling the connector 4, the connector 4 is inserted into the mounting seat 2 through the assembly groove 21, and the assembly groove 21 initially limits the connector 4; When assembling the mounting panel 5, align the easily detachable buckle 6 with the mounting groove 11 on the printed circuit board 1 and insert it therein to complete the assembly between the mounting panel 5 and the printed circuit board 1. Since the engagement amount of the easily detachable buckle 6 is small, the mounting panel 5 and the printed circuit board 1 can be easily separated, making it convenient to remove the connector and replace or repair the connector 4. It is suitable for long-term plug-in and pull-out assembly of the connector 4 and excessive wear, making it convenient to replace it; When in use, align the mounting opening 75 on the protective sleeve 7 with the plug-in position and insert it. When the protective sleeve 7 contacts the outer contour of the plug-in position, the protective sleeve 7 stops moving, while the printed circuit board 1, the mounting seat 2, the connector 4 and the mounting panel 5 continue to move, and the elastic member 71 is compressed. At the same time, the limiting component 8 approaches the printed circuit board 1, and the limiting component 8 is aligned with 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 seat 2 and the printed circuit board 1, and reducing relative movement. At the same time, the buckling amount of the easy-to-remove buckle 6 is increased, and the connection strength between the mounting panel 5 and the printed circuit board 1 is increased. The spacing between the mounting panel 5 and the printed circuit board 1 is relatively fixed, and the mounting seat 2 and the connector 4 between the mounting panel 5 and the printed circuit board 1 are also relatively fixed. After the plugging is completed, the printed circuit board 1 is fixed to the plug body to complete the plugging of the connector assembly. In summary, a difficult-to-remove clip 3 is used to connect the mounting base 2 to the printed circuit board 1. Although a certain gap initially exists due to the structural characteristics of the anti-return surface of the difficult-to-remove clip 3 and the anti-return component (in this embodiment, the anti-return component is the printed circuit board 1), this connection method can provide extremely high connection strength, effectively preventing the mounting base 2 and the printed circuit board 1 from being pulled apart with great force, preventing damage to the printed circuit board 1, and ensuring the stability of the device structure. The mounting panel 5 is connected to the printed circuit board 1 using an easy-to-remove clip 6. Because the easy-to-remove clip 6 has a small engagement, the two can be easily separated, greatly facilitating the removal, replacement, or repair of the connector 4. It is particularly suitable for replacement operations after the connector 4 has been excessively worn due to long-term plug-in and unplugging, thereby improving the maintainability of the device.

[0024] During use, when the protective cover 7 stops moving against the outer contour of the plug-in position, while other components continue to move, the elastic member 71 is compressed, and the limit assembly 8 approaches the printed circuit board 1 and squeezes the difficult-to-remove buckle 3 and the easy-to-remove buckle 6; it not only increases the resistance to the movement of the difficult-to-remove buckle 3, reduces the risk of relative movement between the mounting seat 2 and the printed circuit board 1, but also increases the buckling amount of the easy-to-remove buckle 6, improves the connection strength between the mounting panel 5 and the printed circuit board 1, and makes the distance between the mounting panel 5 and the printed circuit board 1 relatively fixed, thereby ensuring the relative position stability of the mounting seat 2 and the connector 4, and finally completing the plug-in of the connector assembly while ensuring the stability and reliability of the entire assembly after plug-in, thereby improving the overall performance of the equipment.

[0025] In addition, during the plug-in process, the printed circuit board 1 is subjected to thrust and is transmitted to the mounting seat 2, the connector 4 and the mounting panel 5 in sequence. After the printed circuit board 1 is fixed to the plug-in body, the various components are in a tightly fitted state when plugged in, ensuring that they are in a sealed state during use, which can prevent dust, moisture and other impurities from entering the equipment, corroding and damaging the connectors and circuits, and reducing the reliability and service life of the equipment.

[0026] As a further solution of the present invention, the difficult-to-remove buckle 3 includes: A short deflected beam 31 , which is elastic and fixed to the mounting base 2 ; The anti-return member 32 is fixed to the end of the short deflection beam 31 and is provided with a first clearance surface 33 and an anti-return plane 34 connected end to end; The anti-return member 32 moves into the mounting groove 11, allowing the positioning surface 33 to contact the side wall of the mounting groove 11, so that the short deflection beam 31 is deformed, making it easier for the anti-return member 32 to pass over the mounting groove 11, thereby achieving the assembly of the mounting seat 2 and the printed circuit board 1; Combine Figure 2-Figure 5 As shown, during the assembly process of the mounting seat 2 and the printed circuit board 1, the anti-return member 32 needs to be aligned with the mounting groove 11 and inserted. When the yield surface 33 of the anti-return member 32 contacts the side wall of the mounting groove 11, the anti-return member 32 will deflect, thereby causing the short deflection beam 31 to bend and accumulate elastic potential energy. The deflection process causes the anti-return member 32 to stagger with the side wall of the mounting groove 11, creating conditions for the subsequent insertion action; after the anti-return member 32 passes over the mounting groove 11, the elastic force accumulated in the short deflection beam 31 is released, causing it to return to a vertical state, and driving the anti-return member 32 to partially overlap with the side wall of the mounting groove 11; at this time, the anti-return plane 34 of the anti-return member 32 can effectively limit the reverse movement of the anti-return member 32, thereby successfully completing the assembly of the mounting seat 2 and the printed circuit board 1; Based on mechanical analysis, when the deflection beam deflects at the same angle, the shorter the deflection beam itself, the greater the force required to remove or insert it. Based on this, this design uses a short deflection beam 31 between the mounting base 2 and the printed circuit board 1. This design further increases the difficulty of removing the mounting base 2 from the printed circuit board 1, effectively improving the stability of the connection between the two.

[0027] As a further solution of the present invention, the easily detachable buckle 6 includes: The long deflection beam 61 has an inclined side wall and is elastic, and the long deflection beam 61 is fixed to the mounting panel 5; The second anti-return member 62 is fixedly mounted on the end of the long deflection beam 61 and is provided with a second yielding surface 63 and an anti-return inclined surface 64 connected end to end; The second anti-return member 62 moves into the installation groove 11, allowing the second positioning surface 63 to contact the side wall of the installation groove 11, so that the long deflection beam 61 is deformed, making it easier for the second anti-return member 62 to pass over the installation groove 11, thereby achieving the assembly of the installation panel 5 and the printed circuit board 1; Combine Figure 2-Figure 4 and Figure 6As shown, during the assembly process of the installation panel 5 and the printed circuit board 1, the anti-return component 2 62 needs to be aligned with the installation groove 11 and inserted. When the yield surface 2 63 of the anti-return component 2 62 contacts the side wall of the installation groove 11, the anti-return component 2 62 will deflect, thereby causing the long deflection beam 61 to bend and accumulate elastic potential energy. This deflection action causes the anti-return component 2 62 to be offset from the side wall of the installation groove 11, creating conditions for the subsequent insertion action. After the anti-return component 2 62 passes over the installation groove 11, the elastic force accumulated in the long deflection beam 61 is released, returning to a vertical state, and driving the anti-return component 2 62 to partially overlap with the side wall of the installation groove 11. At this time, the anti-return inclined surface 64 of the anti-return component 2 62 can limit the reverse movement of the anti-return component 2 62, thereby successfully completing the assembly of the installation panel 5 and the printed circuit board 1.

[0028] Since the anti-return slope 64 is set at an angle, when external force is applied to try to pull out the anti-return member 2 62, the resistance borne by the mounting groove 11 is relatively small, which makes it easy to pull the mounting panel 5 out of the printed circuit board 1, greatly facilitating the removal, replacement or maintenance of the connector 4.

[0029] In addition, when the inclined anti-return bevel 64 presses the side wall of the installation groove 11, according to the principle of force interaction, the installation groove 11 will exert a downward force on the anti-return bevel 64 (such as Figure 10 The anti-return bevel 64 transmits this force to the mounting panel 5. After the connector assembly is plugged in, this force causes the mounting panel 5 to maintain its tendency to move toward the printed circuit board 1, thereby making the various components of the connector assembly fit tightly together, effectively improving the sealing performance of the entire assembly.

[0030] As a further solution of the present invention, the limiting assembly 8 includes a sliding sleeve 81 fixed in the protective sleeve 7, and the sliding sleeve 81 is slidably provided with an extrusion block 82. The side wall of the extrusion block 82 is inclined and can be embedded between the difficult-to-remove buckle 3 and the easy-to-remove buckle 6; a delay spring 83 is fixed between the extrusion block 82 and the sliding sleeve 81; when the connector 4 is unplugged, the elastic force of the delay spring 83 is released, delaying the time for the extrusion block 82 to move; See also Figure 2-Figure 4 as well as Figure 7 As the protective sleeve 7 moves relative to the printed circuit board 1, the sliding sleeve 81, with the aid of the time-delay spring 83, drives the extrusion block 82 toward the printed circuit board 1. When the extrusion block 82 contacts the difficult-to-remove buckle 3 and the easily-to-remove buckle 6, the time-delay spring 83 is compressed. Simultaneously, the extrusion block 82 exerts a compressive force on the difficult-to-remove buckle 3 and the easily-to-remove buckle 6, forcing them against the sidewalls of the mounting slot 11. This compressive force gradually increases as the sliding sleeve 81 descends further.

[0031] When the connector assembly needs to be unplugged, the protective sleeve 7 moves relative to the printed circuit board 1 under the action of the elastic member 71, and the sliding sleeve 81 moves accordingly. At this time, the extrusion block 82 is embedded between the difficult-to-remove buckle 3 and the easily-to-remove buckle 6, and the delay spring 83 rebounds to compensate for the displacement. When the sliding sleeve 81 exerts a pulling force on the extrusion block 82 through the delay spring 83, overcoming the resistance of the difficult-to-remove buckle 3 and the easily-to-remove buckle 6 to the extrusion block 82, the extrusion block 82 disengages from the difficult-to-remove buckle 3 and the easily-to-remove buckle 6. This allows the difficult-to-remove buckle 3 and the easily-to-remove buckle 6 to return to normal. When the connector is not in use, the easily-to-remove buckle 6 can be easily removed, making it easier to replace the connector.

[0032] It is worth noting that during the removal of the connector assembly, the extrusion block 82 does not immediately disengage from the difficult-to-remove buckle 3 and the easy-to-remove buckle 6. This design ensures that sufficient resistance is maintained between the mounting panel 5 and the mounting base 2 during the initial stages of the removal process, effectively preventing the assembly from disintegrating during the removal process and ensuring stability and safety throughout the entire operation.

[0033] As a further solution of the present invention, an auxiliary sleeve 9 is slidingly provided on the side wall of the mounting seat 2, and a wedge block 91 is fixed on the side wall of the short deflection beam 31. The auxiliary sleeve 9 moves along the mounting seat 2 and can squeeze the wedge block 91 to deform the short deflection beam 31 and disengage the anti-return member 32 from the mounting groove 11; an elastic bracket 92 is installed between the auxiliary sleeve 9 and the mounting seat 2, and the elastic bracket 92 is used to reset the auxiliary sleeve 9; To remove the mounting base 2 from the printed circuit board 1, the operator must move the auxiliary sleeve 9 toward the printed circuit board 1. During this process, the auxiliary sleeve 9 exerts a compressive force on the wedge block 91, which in turn compresses the short deflection beam 31, causing it to deform. As the short deflection beam 31 deforms, the check member 1 32 disengages from the mounting groove 11. This design is particularly suitable for simultaneously disengaging multiple difficult-to-remove clips 3, effectively reducing the difficulty of disassembly of the mounting base 2 and improving disassembly efficiency.

[0034] As the auxiliary sleeve 9 is moved toward the printed circuit board 1, the elastic bracket 92 deforms due to the external force and accumulates elastic potential energy. Once the mounting base 2 is successfully removed, the operator releases the auxiliary sleeve 9, and the elastic bracket 92 releases the stored elastic potential energy, automatically returning the auxiliary sleeve 9 to its initial position, ready for the next removal.

[0035] As a further solution of the present invention, a dustproof structure is installed at the end of the protective sleeve 7, and the dustproof structure includes: The plugs 72 are arranged in a circular array and elastically slide with the protective sleeve 7 via a spring sheet 73; the plugs 72 can together seal the installation opening 75; Trigger 74 is tilted and elastic, fixed to plug 72. When the portion mating with connector 4 contacts trigger 74, the tilted trigger 74 drives plug 72 to move in all directions, exposing mounting opening 75. When the connector assembly is removed, spring 73, by virtue of its elastic properties, returns plug 72 to its initial position. At this point, mounting opening 75 returns to its closed state. In this state, mounting opening 75 remains tightly closed, effectively preventing external contaminants such as dust and moisture from entering the connector assembly, thereby preventing these contaminants from adversely affecting the performance of the connector assembly and ensuring the stability and reliability of the connector assembly during subsequent use.

[0036] As a further embodiment of the present invention, connector 4 is fixed with a rectangular plate 41 that matches the mounting groove 21. An annular snap 22 is fixed to the inner side of mounting base 2. A slot 42 is formed in the sidewall of connector 4 to mate with the annular snap 22. Slot 42 engages with annular snap 22 to provide preliminary positioning for connector 4. Before mounting panel 5 is fully installed, this locking structure provides a preliminary stop for connector 4, effectively preventing it from accidentally falling due to external forces. Furthermore, the presence of rectangular plate 41 limits the rotation of connector 4, preventing it from rotating during operation and causing bending and deformation of the pins inserted into printed circuit board 1.

[0037] As a further solution of the present invention, the mounting base 2 is fixed with a circumferential buckle 23, and the mounting panel 5 is provided with a through hole that cooperates with the circumferential buckle 23; a cone 24 is fixed on the inner side of the protective sleeve 7, and the cone 24 is coaxially arranged with the circumferential buckle 23; the circumferential buckle 23 cooperates with the through hole to realize the assembly of the mounting base 2 and the mounting panel 5, and further limits the connector 4 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 therewith and enters the inside of the circumferential buckle 23. During the movement, the cone 24 exerts an extrusion effect on the top of the circumferential buckle 23, causing the circumferential outer diameter of the top of the circumferential buckle 23 to increase. This change not only makes the fit between the circumferential buckle 23 and the through hole tighter, but also can exert a thrust on the mounting panel 5 directed towards the mounting base 2, further improving the stability of the connector 4 in use.
