Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular discloses a stacking connector. Background Art

[0002] With the rapid development of the connector industry, customers have increasingly higher requirements for the performance of connectors. In order to meet the connection requirements of these complex circuit boards, connectors, as an indispensable component in electronic devices, have higher and higher performance and reliability requirements. However, in actual applications, due to improper operation or unreasonable connector design, problems such as mis-insertion and looseness often occur, which not only affects the normal operation of electronic devices, but may also cause damage to the equipment and even cause safety accidents. Therefore, it is particularly important to develop a connector that has both fool-proof functions and can ensure firm fixation. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a

[0004] To achieve the above object, a stacking connector of the present invention comprises a first housing, a second housing and a fixing assembly used in conjunction with the housings, wherein a first slot for accommodating a terminal group is provided on the housing; The fixing component includes a rib, which is located at both ends of the second shell. A second groove is provided on the rib. A strip made of elastic material is provided in the second groove. The strip is provided with a protrusion protruding from the end face of the rib. The second groove runs through the second shell. A pressing piece is provided at the connection between the strip bodies at both ends. The pressing piece cooperates with the strip to move the protrusion. The first shell also has a fourth groove for accommodating the rib and the protrusion. A fifth groove is also provided on the first shell. The fifth groove is connected to the fourth groove to accommodate the protrusion.

[0005] Furthermore, through the design of the strip and protrusion in the fixing assembly, the user can easily operate the strip through the pressing piece to move the protrusion. This makes the connection between the first shell and the second shell more flexible and easy to assemble and disassemble. The strip made of elastic material can be deformed when under pressure, but then quickly return to its original shape. This feature allows the protrusion to be firmly stuck in the fourth groove on the first shell, ensuring a stable connection between the two shells. The strip made of elastic material has high wear resistance and fatigue resistance, and can maintain its elasticity and shape stability for a long time, thereby extending the service life of the electrical connector. The stable connection and easy-to-operate design can ensure that the electrical connector will not accidentally fall off or loosen during use, thereby improving the safety and reliability of the electrical connection.

[0006] Furthermore, the protrusion includes a first magnetic part, and an elastic part is accommodated on the fifth groove body. A second magnetic part for cooperating with the first magnetic part is provided on a side of the elastic part close to the first magnetic part. The size of the second magnetic part is smaller than that of the elastic part and larger than that of the fifth groove body. The magnetic force between the first magnetic part and the second magnetic part can ensure that the position of the protrusion in the fifth groove body is more stable, and the firmness of the connection can be maintained even in a vibration or impact environment. The user does not need to apply excessive force to move the protrusion through the pressing part, because the magnetic force will assist the movement of the protrusion to a certain extent, making the assembly and disassembly process smoother, and the magnetic force can guide the protrusion to accurately enter the fifth groove The fifth slot body is connected to the protrusion, thereby avoiding connection errors or damages caused by improper operation. Even if there is a slight gap or tolerance between the protrusion and the fifth slot body, the magnetic force can effectively make up for these differences to ensure the tightness and reliability of the connection. In addition to physical locking such as the fit between the protrusion and the slot body, the magnetic force also provides an additional locking mechanism to further enhance the stability of the connection. The magnetic force can reduce the direct friction between the protrusion and the slot body, thereby reducing wear and noise and extending the service life of the electrical connector. Due to the existence of the magnetic force, even after long-term use, the fit between the protrusion and the slot body will not become too tight or difficult to separate, thereby facilitating subsequent maintenance and replacement.

[0007] Further, the first magnetic member and the second magnetic member are respectively provided with a first magnetic isolation layer and a second magnetic isolation layer, the first magnetic isolation layer and the second magnetic isolation layer respectively half-cover the first magnetic member and the second magnetic member, the first magnetic member and the second magnetic member are close to each other with opposite magnetic poles and no coating layer, and the design of the first magnetic isolation layer can limit the diffusion of magnetic lines of force, so that the magnetic force is mainly concentrated on the side of the magnetic member that is not covered, that is, the side close to each other. This enhances the directionality of the magnetic force, making the magnetic force between the first magnetic member and the second magnetic member more clear and effective, and the magnetic isolation layer can isolate and reduce the magnetic interference of the magnetic member to other electrical components or systems. This is crucial to maintaining the stability and reliability of the electrical connector, especially in a magnetically sensitive environment, because the magnetic force is mainly concentrated on the side close to each other, which helps to guide the protrusion to accurately enter the fifth slot body, improves the precision and accuracy of the connection, and the magnetic force is more concentrated and strong on the side close to each other, which helps to enhance the stability of the connection, and even in a vibration or impact environment, the tightness of the connection can be maintained, and the magnetic isolation layer can provide a certain protection for the magnetic member to prevent it from being damaged or losing its magnetism. This extends the service life of the electrical connector and reduces maintenance costs. By adjusting the thickness and material of the magnetic isolation layer, the size and distribution of the magnetic force can be further optimized to meet the needs of different application scenarios.

[0008] Furthermore, an elastic member is also contained in the fifth slot body, and the elastic member is located on the side of the second magnetic member away from the first magnetic member. The elastic member can effectively absorb and disperse the impact force and vibration generated during the connection process, thereby protecting the first magnetic member and the second magnetic member from damage. This buffering performance helps to extend the service life of the electrical connector and improve its reliability. The presence of the elastic member makes the connection between the first magnetic member and the second magnetic member tighter and more stable. Even in a vibrating or impact environment, the elastic member can provide additional support and fixing to ensure the stability of the connection. The elastic member can adjust the spacing between the first magnetic member and the second magnetic member, thereby optimizing the effect of the magnetic force. Through appropriate adjustment, it can be ensured that the magnetic force is strong enough to maintain the connection, but not too large to cause difficulty in operation. The elastic member can reduce the direct friction between the first magnetic member and the second magnetic member, thereby reducing wear and noise. A layer of metal sheet (such as copper sheet, steel sheet, etc.) is embedded or attached to the elastic member. When the first magnetic member and the second magnetic member are in contact, the metal sheet will deform and emit a crisp sound to achieve a reminder function.

[0009] Furthermore, the second shell body is provided with a second terminal group, and the first terminal group is used in conjunction with the second terminal group to realize the transmission of power and signals. The coordinated use of the first terminal group and the second terminal group can ensure the fast and stable transmission of power and signals between devices. This design usually optimizes the connection structure between the terminals, reduces the resistance and time during the connection process, thereby improving the overall connection efficiency. Through a reasonable terminal group design, it can be ensured that the terminals maintain a good contact state during long-term use. This design helps to reduce problems such as signal attenuation or power interruption caused by poor contact, thereby enhancing the stability of the connection. The coordination of the first terminal group and the second terminal group can simplify the overall design structure of the connector.

[0010] Furthermore, the first terminal group includes a signal female terminal and a power female terminal. A signal clamp spring is arranged on the signal female terminal, and the signal clamp spring is used to protect and fix the signal female terminal. The power female terminal is provided with a power clamp spring and a torsion spring for protecting and fixing the power female terminal. The signal clamp spring can firmly fix the signal female terminal to prevent it from loosening or falling off due to external force during the connection process. This fixing method helps to ensure the stability and reliability of signal transmission and reduce signal attenuation or interruption caused by poor connection. The signal clamp spring is usually made of high-quality materials and has high strength and durability. It can maintain stable performance during long-term use and is not easy to be damaged or deformed, thereby extending the service life of the signal female terminal. The design of the signal clamp spring makes the assembly process of the signal female terminal simpler and faster, and it does not require complicated The assembly can be completed with tools or steps, which reduces the assembly cost and time. The benefits of the power female terminal, power retaining spring and torsion spring protect the power connection. The power retaining spring and torsion spring act together on the power female terminal to provide it with double protection. They can prevent the power female terminal from being damaged or deformed due to external force during the connection process, thereby ensuring the safety and stability of power transmission. The design of the power retaining spring and torsion spring helps to maintain good contact between the power female terminal and the corresponding connecting parts. This contact state can reduce contact resistance and improve conductivity, thereby ensuring efficient transmission of power. The torsion spring has a certain elasticity and can play a buffering role when the equipment is vibrated or impacted. It can reduce the relative movement between the power female terminal and the connecting parts, thereby avoiding poor connection or damage caused by vibration or impact.

[0011] Furthermore, a first strip groove is provided on the fixing component, and a baffle is also provided on the fixing component. The first strip groove is used to prevent mistakes and avoid incorrect connection between the fixing component and the first shell and the second shell. The baffle is used to enhance the connection strength between the terminal group and the second shell. The baffle is used to stop the protrusion on the fixing component to limit the terminal in the first shell. The design of the first strip groove can be used as a visual and physical guide to ensure that the fixing component can only be connected to the first shell and the second shell in the correct way. This design helps to prevent connection errors caused by improper operation or negligence, thereby improving the assembly accuracy and reliability of the product. The fool-proof design makes the assembly process more intuitive and simple, and reduces the requirements for the skill level of the operator, which helps to reduce assembly time, improve production efficiency, and reduce rework costs caused by assembly errors. The baffle can effectively increase the connection strength between the terminal group and the shell by stopping the protrusion on the first shell. This design makes the connection between the components more stable and can withstand greater external forces and vibrations, thereby improving the durability and reliability of the product. The baffle not only enhances the connection strength, but also has a limiting effect. It can ensure the correct position of the terminal in the housing and prevent it from loosening or shifting due to vibration or external force, which helps to maintain the stability of the product's electrical and mechanical properties and ensure the normal operation of the product. By enhancing the connection strength and limiting effect, the baffle helps to improve the overall structural stability of the product, which can reduce safety hazards caused by loose or falling components and ensure the safe use of the product in various environments.

[0012] Furthermore, the fixing assembly also includes a stopper, and an extension for clamping the stopper is provided at both ends of the shell. The extension cooperates with the stopper to limit the first shell and the second shell. The cooperation between the stopper and the extension can ensure the stability of the first shell and the second shell at the connection point, and prevent the two from being relatively displaced or deformed when subjected to external force. This stable connection structure helps to improve the rigidity and durability of the entire fixing assembly. Through the precise cooperation between the stopper and the extension, the alignment accuracy of the first shell and the second shell during the assembly process can be ensured. This high-precision assembly helps to reduce assembly errors and improve the performance and reliability of the entire fixing assembly. The design of the stopper and the extension makes the assembly process simpler and faster. The assembler only needs to insert the stopper into the extension to complete the connection between the two without additional complex operations or tools. When it is necessary to maintain or replace the parts of the fixing assembly, the cooperation design of the stopper and the extension makes the disassembly process easier. This design helps to reduce maintenance costs and time and improve the maintainability of the entire fixing assembly. By adjusting the position or type of the stopper, the connection requirements of the first shell and the second shell of different sizes or shapes can be adapted.

[0013] Furthermore, the first housing is also provided with a positioning column for the connector to be installed with an external object. The positioning column is used to prevent the connector from being misaligned during installation. The design of the positioning column enables the connector to be accurately aligned and fixed at a predetermined position during installation. This design helps to reduce the problem of installation misalignment caused by improper assembly or operating errors, thereby improving the assembly accuracy and reliability of the entire system. The positioning column serves as an intuitive assembly guide, making the assembly process simpler and clearer. The operator only needs to align the positioning hole of the connector with the positioning column of the housing to easily complete the assembly work without the need for additional complex operations or tools. The cooperation between the positioning column and the positioning hole can increase the connection strength between the connector and the housing.

[0014] Furthermore, a third groove is provided on the second shell, and the third groove is used for inserting an external sheet-like jig into the terminal group and disassembling the second shell. The third groove is used to accommodate an external sheet-like jig. After the external sheet-like jig is inserted, the free end of the baffle is squeezed to separate it from the protrusion, and then the second shell is pulled to enable the terminal group to be removed from the accommodating blind groove, and the operation is convenient and quick.

[0015] Furthermore, the first shell, the second shell and the fixed component are integrally injection molded. The integral injection molding process can separately mold the first shell, the second shell and the fixed component into a whole at one time, thereby greatly simplifying the production process. This process reduces the assembly process and the required labor costs, so that the production efficiency is significantly improved. The integral injection molding reduces the number of parts and the material waste in the assembly process, thereby reducing the production cost. In addition, since the assembly process is reduced, the scrap rate and rework rate caused by improper assembly are also reduced, further saving costs. The integral injection molding makes the connection between the first shell, the second shell and the fixed component tighter and firmer. This tight connection helps to enhance the structural strength of the entire product, so that it can withstand greater external forces and vibrations.

[0016] Beneficial effects of the present invention: by designing an electrical connector including a first shell, a second shell and a fixing assembly, and ingeniously using a combination of a strip body, a protrusion, a pressing piece, a magnetic piece, and a magnetic isolation layer and an elastic piece, multiple significant benefits are achieved, not only making the assembly and disassembly process of the electrical connector more flexible and smooth, but also ensuring the stability and reliability of the connection between the first shell and the second shell, the cooperation between the protrusion and the groove body, and the introduction of magnetic force, provide an additional locking mechanism, which can maintain the tightness of the connection even in a vibration or impact environment. At the same time, the design of the magnetic isolation layer enhances the directionality of the magnetic force, reduces magnetic interference, and improves the precision and accuracy of the connection. The addition of the elastic piece effectively absorbs the impact force and vibration during the connection process, protects the magnetic piece from damage, and provides additional support and fixing. In addition, the metal sheet on the elastic piece can also emit a warning sound when the magnetic piece contacts, further enhancing the user experience. In summary, these designs jointly improve the performance, stability and service life of the electrical connector, bringing users a safer, more reliable and convenient electrical connection experience.

DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] See also Figures 1 to 10 As shown, a stacking connector of the present invention comprises a first shell 11, a second shell 12 and a fixing assembly 1 used in conjunction with the shells, wherein a first slot 3 for accommodating a terminal group is provided on the shell; the fixing assembly 1 comprises a rib 5, the rib 5 is located at both ends of the second shell 12, a second slot 51 is provided on the rib 5, a strip body 2 made of elastic material is provided in the second slot 51, a protrusion 511 protruding from the end face of the rib 5 is provided on the strip body 2, the second slot 51 passes through the second shell 12, a pressing piece 14 is provided at the connection between the strip bodies 2 at both ends, and the protrusion 511 is moved by the pressing piece 14 in conjunction with the strip body 2; the first shell 11 further comprises a fourth slot 512 for accommodating the rib 5 and the protrusion 511, and the first shell 11 further comprises a fifth slot 513, the fifth slot 513 is connected to the fourth slot 512 to accommodate the protrusion 511.

[0021] Specifically, the pressing member 14 includes a button member and a rod member. The button member squeezes the strip body 2 through the rod member to separate the protrusion 511 from the fifth groove 513. The rod member is slidably arranged on the second shell 12. The bottom end of the rod member is fixedly arranged on the strip body 2 or is provided with a limiting member (such as an annular protrusion) to prevent it from moving out.

[0022] Specifically, through the design of the strip body 2 and the protrusion 511 in the fixing assembly 1, the user can easily operate the strip body 2 through the pressing piece 14 to move the protrusion 511. This makes the connection between the first shell 11 and the second shell 12 more flexible and easy to assemble and disassemble. The strip body 2 made of elastic material can be deformed when subjected to pressure, but then it can quickly return to its original shape. This feature allows the protrusion 511 to be firmly stuck in the fourth groove 512 on the first shell 11 to ensure a stable connection between the two shells. The strip body 2 made of elastic material has high wear resistance and fatigue resistance, and can maintain its elasticity and shape stability for a long time, thereby extending the service life of the electrical connector. The stable connection and easy-to-operate design can ensure that the electrical connector will not accidentally fall off or loosen during use, thereby improving the safety and reliability of the electrical connection.

[0023] Specifically, the protrusion 511 includes a first magnetic member 5111, and an elastic member 5133 is arranged on the fifth groove 513. A second magnetic member 5131 for cooperating with the first magnetic member 5111 is arranged on a side of the elastic member 5133 close to the first magnetic member 5111. The size of the second magnetic member 5131 is smaller than that of the elastic member 5133 and larger than that of the fifth groove 513. The magnetic force between the first magnetic member 5111 and the second magnetic member 5131 can ensure that the position of the protrusion 511 in the fifth groove 513 is more stable, and the connection can be maintained firmly even in a vibration or impact environment. The user does not need to exert excessive force to move the protrusion 511 through the pressing member 14, because the magnetic force will assist the movement of the protrusion 511 to a certain extent, making the assembly and disassembly process smoother. The magnetic force can guide the protrusion 511 to enter the fifth slot 513 accurately, avoiding connection errors or damages caused by improper operation. Even if there is a small gap or tolerance between the protrusion 511 and the fifth slot 513, the magnetic force can effectively make up for these differences to ensure the tightness and reliability of the connection. In addition to physical locking such as the fit between the protrusion 511 and the slot, the magnetic force also provides an additional locking mechanism to further enhance the stability of the connection. The magnetic force can reduce the direct friction between the protrusion 511 and the slot, thereby reducing wear and noise and extending the service life of the electrical connector. Due to the existence of the magnetic force, even after long-term use, the fit between the protrusion 511 and the slot will not become too tight or difficult to separate, thereby facilitating subsequent maintenance and replacement.

[0024] Specifically, the first magnetic member 5111 and the second magnetic member 5131 are respectively provided with a first magnetic isolation layer 5112 and a second magnetic isolation layer 5132, and the first magnetic isolation layer 5112 and the second magnetic isolation layer 5132 are respectively provided to semi-cover the first magnetic member 5111 and the second magnetic member 5131, and the first magnetic member 5111 and the second magnetic member 5131 are close to each other on opposite magnetic poles and are not provided with a coating layer. The design of the first magnetic isolation layer 5112 can limit the diffusion of magnetic lines of force, so that the magnetic force is mainly concentrated on the side of the magnetic member that is not covered, that is, the side that is close to each other, thereby enhancing the directionality of the magnetic force, making the magnetic force between the first magnetic member 5111 and the second magnetic member 5131 more clear and effective, and the magnetic isolation layer can isolate The invention can isolate and reduce the magnetic interference of magnetic parts on other electrical components or systems, especially in a magnetically sensitive environment. Since the magnetic force is mainly concentrated on the adjacent side, it helps to guide the protrusion 511 to accurately enter the fifth slot 513, thereby improving the precision and accuracy of the connection. The magnetic force is more concentrated and stronger on the adjacent side, which helps to enhance the stability of the connection and maintain the tightness of the connection even in a vibration or impact environment. The magnetic isolation layer can provide certain protection for the magnetic parts to prevent them from being damaged or losing their magnetism, thereby extending the service life of the electrical connector and reducing maintenance costs. By adjusting the thickness and material of the magnetic isolation layer, the size and distribution of the magnetic force can be further optimized to meet the needs of different application scenarios.

[0025] Specifically, the fifth groove body 513 also contains an elastic member 5133, which is located on the side of the second magnetic member 5131 away from the first magnetic member 5111. The elastic member 5133 can effectively absorb / disperse the impact force and vibration generated during the connection process, thereby protecting the first magnetic member 5111 and the second magnetic member 5131 from damage, which can help to extend the service life of the electrical connector and improve its reliability. The presence of the elastic member 5133 makes the connection between the first magnetic member 5111 and the second magnetic member 5131 tighter and more stable. Even in a vibration or impact environment, the elastic member 5133 can provide additional support and fixing to ensure the stability of the connection. The elastic member 5133 can adjust the distance between the first magnetic member 5111 and the second magnetic member 5131, thereby optimizing the effect of the magnetic force. Through proper adjustment, it can be ensured that the magnetic force is strong enough to maintain the connection but not too strong to cause difficulty in operation. The elastic member 5133 can reduce the direct friction between the first magnetic member 5111 and the second magnetic member 5131, thereby reducing wear and noise. A layer of metal foil (such as copper foil, steel foil, etc.) is embedded or attached to the elastic member 5133. When the first magnetic member 5111 and the second magnetic member 5131 are in contact, the metal foil will deform and make a crisp sound to achieve a reminder function.

[0026] Specifically, the second shell 12 is provided with a second terminal group 121, and the first terminal group 41 is used in conjunction with the second terminal group 121 to realize the transmission of power and signals. The coordinated use of the first terminal group 41 and the second terminal group 121 can ensure the rapid and stable transmission of power and signals between devices. This design usually optimizes the connection structure between the terminals, reduces the resistance and time during the connection process, thereby improving the overall connection efficiency. Through a reasonable terminal group design, it can ensure that the terminals maintain a good contact state during long-term use, which helps to reduce problems such as signal attenuation or power interruption caused by poor contact, thereby enhancing the stability of the connection. The coordination of the first terminal group 41 and the second terminal group 121 can simplify the overall design structure of the connector.

[0027] Specifically, in other embodiments, the first terminal group 41 and the second terminal group 121 are respectively integrated on the external plate member 18, and the terminal groups are clamped and arranged with the shell via the plate member 18.

[0029] Specifically, the first terminal group 41 includes a signal female terminal 411 and a power female terminal 413. The signal female terminal 411 is provided with a signal spring 412, and the signal spring 412 is used to protect and fix the signal female terminal 411. The power female terminal 413 is provided with a power spring 414 and a torsion spring 415 for protecting and fixing the power female terminal 413. The signal spring 412 can firmly fix the signal female terminal 411 to prevent it from loosening or falling off due to external force during the connection process, thereby reducing signal attenuation or interruption caused by poor connection. The signal spring 412 is usually made of high-quality materials and has high strength and durability. It can maintain stable performance during long-term use and is not easily damaged or deformed, thereby extending the service life of the signal female terminal 411. The design of the signal spring 412 makes the assembly process of the signal female terminal 411 simpler and faster, reducing The assembly cost and time are reduced. The power female terminal 413, the power spring 414 and the torsion spring 415 protect the power connection. The power spring 414 and the torsion spring 415 act together on the power female terminal 413 to provide it with double protection, which can prevent the power female terminal 413 from being damaged or deformed due to external force during the connection process, thereby ensuring the safety and stability of power transmission. The design of the power spring 414 and the torsion spring 415 helps to maintain good contact between the power female terminal 413 and the corresponding connecting parts. This contact state can reduce contact resistance and improve conductivity, thereby ensuring efficient transmission of power. The torsion spring 415 has a certain elasticity and can play a buffering role when the equipment is vibrated or impacted, thereby reducing the relative movement between the power female terminal 413 and the connecting parts, thereby avoiding poor connection or damage caused by vibration or impact.

[0030] Specifically, a first strip groove 9 is provided on the fixing component 1, and a baffle 13 is also provided on the fixing component 1. The first strip groove 9 is used to prevent mistakes and avoid incorrect connection between the fixing component 1 and the first shell 11 and the second shell 12. The baffle 13 is used to enhance the connection strength between the terminal group and the second shell 12. The baffle 13 is used to stop the protrusion on the first shell 11 to limit the terminal in the first shell 11. The design of the first strip groove 9 can be used as a visual and physical guide to ensure that the fixing component 1 can only be connected to the first shell 11 and the second shell 12 in the correct way, which helps to prevent improper operation or The connection errors caused by negligence can be prevented, thereby improving the assembly accuracy and reliability of the product. The fool-proof design makes the assembly process more intuitive and simple, and reduces the requirements for the skill level of the operator, which helps to reduce assembly time, improve production efficiency, and reduce the rework cost caused by assembly errors. The baffle 13 can effectively increase the connection strength between the terminal group and the shell by resisting the protrusion on the first shell 11, making the connection between the components more stable and able to withstand greater external forces and vibrations, thereby improving the durability and reliability of the product. The baffle 13 not only enhances the connection strength, but also has a limiting effect. It can ensure that the terminal is correctly positioned in the shell to prevent it from loosening or shifting due to vibration or external forces, which helps to maintain the stability of the electrical and mechanical properties of the product and ensure the normal operation of the product. By enhancing the connection strength and limiting effect, the baffle 13 helps to improve the overall structural stability of the product, which can reduce the safety hazards caused by loose or falling components and ensure the safe use of the product in various environments.

[0031] Specifically, the fixing assembly 1 also includes a limit piece 22, and an extension part 6 for clamping the limit piece 22 is provided at both ends of the shell. The extension part 6 cooperates with the limit piece 22 to limit the first shell 11 and the second shell 12. The cooperation between the limit piece 22 and the extension part 6 can ensure the stability of the first shell 11 and the second shell 12 at the connection, and prevent the two from relative displacement or deformation when subjected to external force. This stable connection structure helps to improve the rigidity and durability of the entire fixing assembly 1. Through the precise cooperation between the limit piece 22 and the extension part 6, the alignment accuracy of the first shell 11 and the second shell 12 during the assembly process can be ensured, which improves The performance and reliability of the entire fixing component 1 are improved. The design of the limit member 22 and the extension portion 6 makes the assembly process simpler and faster. The assembler only needs to insert the limit member 22 into the extension portion 6 to complete the connection between the two without the need for additional complicated operations or tools. When it is necessary to maintain or replace parts of the fixing component 1, the matching design of the limit member 22 and the extension portion 6 makes the disassembly process easier. This design helps to reduce maintenance costs and time and improve the maintainability of the entire fixing component 1. By adjusting the position or type of the limit member 22, it can adapt to the connection requirements of the first shell 11 and the second shell 12 of different sizes or shapes.

[0032] Specifically, the first shell 11 is also provided with a positioning column 7 for use in installing the connector in conjunction with an external object. The positioning column 7 is used to prevent the connector from being misaligned during installation and to avoid installation misalignment. The design of the positioning column 7 enables the connector to be accurately aligned and fixed in a predetermined position during installation, which helps to reduce installation misalignment problems caused by improper assembly or operational errors, thereby improving the assembly accuracy and reliability of the entire system. The positioning column serves as an intuitive assembly guide, making the assembly process simpler and clearer. The operator only needs to align the positioning hole of the connector with the positioning column of the shell to easily complete the assembly work without the need for additional complex operations or tools. The cooperation between the positioning column and the positioning hole can increase the connection strength between the connector and the shell.

[0033] Specifically, the second shell 12 is provided with a third groove 122, and the third groove 122 is used for inserting an external sheet-like jig into the terminal group and disassembling the second shell 12. The third groove 122 is used to accommodate an external sheet-like jig. After the external sheet-like jig is inserted, it squeezes the free end of the baffle 13 to separate it from the protrusion, and then pulls the second shell 12 to enable the terminal group to be removed from the accommodating blind groove, and the operation is convenient and quick.

[0034] Specifically, the first shell 11, the second shell 12 and the fixed component 1 are integrally molded. The integral injection molding process can mold the first shell 11, the second shell 12 and the fixed component 1 into a whole at one time, thereby greatly simplifying the production process. This process reduces the assembly process and the required labor cost, so that the production efficiency is significantly improved. The integral injection molding reduces the number of parts and the material waste in the assembly process, thereby reducing the production cost. In addition, since the assembly process is reduced, the scrap rate and rework rate caused by improper assembly are also reduced, further saving costs. The integral injection molding makes the connection between the first shell 11, the second shell 12 and the fixed component 1 tighter and firmer, which helps to enhance the structural strength of the entire product so that it can withstand greater external forces and vibrations.
