Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular discloses a lever-type cylinder connector with a 24-pin wire terminal module. Background Technology

[0002] In the field of electrical connector technology, most of the multi-layer terminal fixing modules used in existing cylinder connectors adopt an integral design, which not only leads to complex mold structure and high development costs, but also easily causes quality defects such as insufficient injection molding and dimensional deviations during the production process, resulting in a low product yield. In addition, conventional cylinder connectors also have problems with poor assembly stability and unreliable terminal fixing, making it difficult to meet the actual working conditions. Therefore, connectors are urgently needed to solve the above problems. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a lever-type cylinder connector for a 24-pin wire terminal module.

[0004] To achieve the above objectives, the present invention provides a lever-type cylinder connector for a 24-pin terminal module, comprising a plug-in module. The plug-in module includes a module body, multiple sets of fixing members housed within the module body, and multiple sets of terminal units respectively disposed on the multiple sets of fixing members. All terminal units of the plug-in module are combined to form a signal transmission terminal. The multiple sets of fixing members are connected together to form a fixed module. A limiting snap-fit ​​structure is provided within the module body, and the fixed module is fixed within the module body by means of the limiting snap-fit ​​structure.

[0005] The lever-type cylinder connector also includes a housing, and a plug-in module is disposed within the housing. The housing has a first plug-in channel and a first terminal component located within the first plug-in channel. The plug-in module has a second plug-in channel connected to the first plug-in channel and a second terminal component located within the second plug-in channel. When the housing is plugged into the plug-in module, the first terminal component and the second terminal component form an electrical connection. The first terminal component and the second terminal component are combined to form a terminal group, and the signal transmission terminal is the second terminal component.

[0006] Multiple sets of fasteners are stacked layer by layer. Through a limiting and snap-fit ​​structure within the module body, each set of fasteners is sequentially snapped and fixed inside the module body. The plug-in module is then inserted into the outer shell, connecting the first plug-in channel of the outer shell with the second plug-in channel of the plug-in module. After the outer shell and plug-in module are properly inserted, the first terminal component in the first plug-in channel precisely aligns with the second terminal component in the second plug-in channel, forming a stable electrical connection. The through-channel of the fastener communicates with the second plug-in channel, securely accommodating and limiting the second terminal component, preventing terminal displacement. Compared to traditional integral connectors, this structure offers significant advantages. The layered snap-fit ​​fastener design eliminates the complex integral structure, greatly simplifying the mold structure, reducing mold development costs, minimizing injection molding defects, and improving product yield. It can also flexibly adapt to assembly requirements with different numbers of layers. The limiting and snap-fit ​​structure ensures precise assembly of multi-layer fasteners without skewing or offset, resulting in more accurate terminal alignment and a more stable and reliable electrical connection. The overall assembly operation is simple, and the structure is robust and durable.

[0007] The fasteners are provided in three sets. Each set of fasteners is provided with a set of elastic members on both sides. The module body is provided with a first snap-fit ​​groove for accommodating the elastic members. There are multiple sets of first snap-fit ​​grooves. Each set of first snap-fit ​​grooves cooperates with a set of elastic members. The first snap-fit ​​groove is a limiting snap-fit ​​structure. The fasteners are accommodated in the plug-in module through the snap-fit ​​cooperation between the elastic members and the first snap-fit ​​grooves.

[0008] The elastic element includes a cantilever connecting block, an extension arm, and a limiting block; one end of the cantilever connecting block is connected to the fixing member, and the end of the cantilever connecting block away from the fixing member is connected to the extension arm; the limiting block is located on the side of the extension arm away from the cantilever connecting block and is used to engage and limit the first locking groove; the extension arm can undergo elastic deformation under external force, and the free end of the extension arm protrudes from the insertion end face of the fixing member so that the elastic element can be disassembled and assembled with the first locking groove by pressing the free end.

[0009] A first clearance groove is provided between the fixing component and the elastic component, which provides deformation space for the elastic deformation of the elastic component. A first inclined guide surface is provided on the limiting block. The module body includes a housing part and a flange integrally formed with the housing part. The flange is located at the insertion end face of the housing part. A guide block is provided on the side of the flange near the elastic component. A second inclined guide surface is provided on the guide block. The first inclined guide surface and the second inclined guide surface match each other. When the fixing module is inserted and assembled relative to the module body, the limiting block abuts and guides the first inclined guide surface and the second inclined guide surface, so that the elastic component generates elastic contraction in the first clearance groove, thereby realizing the snap-fit ​​fixing of the limiting block and the first snap-fit ​​groove.

[0010] The elastic component consists of a cantilever connecting block, an extension arm, and a limiting block. The cantilever connecting block is connected to the fixing component. The free end of the extension arm extends out of the insertion end face of the fixing component. A relief groove is provided between the fixing component and the elastic component to provide space for elastic deformation. The limiting block is provided with a first inclined guide surface. The shell part of the module body is integrally formed with a flange. The flange is provided with a guide block with a second inclined guide surface. The two inclined guide surfaces match and guide. When the fixed module is inserted, the elastic component elastically contracts in the relief groove by abutting the guide surface, thereby realizing the automatic locking and fixing of the limiting block and the first locking groove. Pressing the free end of the extension arm can release the locking. The overall structure is convenient to assemble, reliable in positioning, and easy to disassemble and assemble, effectively improving the assembly efficiency and structural stability of the connector.

[0011] The guide block is provided with a first tilt angle. When the elastic element is engaged with the first snap-fit ​​groove, the first tilt angle is located on the side of the limiting block away from the first inclined guide surface. The first tilt angle is 30° to 90°, preferably 80°.

[0012] When the elastic element and the first locking groove are engaged, the first tilt angle is located on the side of the limiting block away from the first tilted guide surface. This can form a reliable limiting stop on the limiting block to prevent the elastic element from accidentally coming loose. At the same time, it works with the tilted guide surface to achieve insertion guidance and automatic engagement, which not only ensures smooth assembly but also improves the locking stability and anti-loosening reliability after engagement.

[0013] The inner sidewall of the module body is provided with multiple sets of guide ribs, and a set of guide ribs is provided between two adjacent sets of first snap-fit ​​grooves. A set of first snap-fit ​​grooves is provided between two adjacent sets of guide ribs. The guide ribs extend along the assembly direction of the fastener and guide and position the fastener during the assembly process.

[0014] When assembling multiple sets of fasteners, multiple sets of guide ribs extending along the assembly direction are used on the inner side wall of the module body. A first snap-fit ​​groove is provided between each pair of adjacent guide ribs, and guide ribs are also provided between adjacent first snap-fit ​​grooves. During the process of the fastener sliding into the first snap-fit ​​groove, its sides and interlayer structure are precisely guided and limited by the guide ribs. Specifically, each set of fasteners is placed into the space between adjacent guide ribs, slides smoothly along the assembly direction of the guide ribs, and snaps into the first snap-fit ​​groove. The guide ribs guide the assembly path of the fasteners and prevent them from tilting, shifting, or getting stuck during the assembly process. The beneficial effects of this structure are that the arrangement of multiple sets of guide ribs creates a regular assembly guide rail, which not only significantly improves the accuracy and smoothness of multi-layer fastener assembly and effectively avoids poor terminal mating caused by assembly deviation; at the same time, the guide ribs and the first snap-fit ​​strip are arranged alternately to form multi-directional limiting clamping for the multi-layer fasteners, enhancing the overall rigidity of the stacked structure, preventing radial loosening or axial displacement of the fasteners during use, significantly improving the connection stability and structural reliability of the connector, and ensuring the long-term stability of the electrical connection.

[0015] The first set of fasteners and the third set of fasteners have the same structure. The first set of fasteners and the third set of fasteners together clamp the second set of fasteners. Both the first set of fasteners and the third set of fasteners include a first body part. The first body part has a square structure. The second set of fasteners includes a second body part and a first vertical part disposed on the second body part. When the first set of fasteners and the second set of fasteners are installed together into the module body, the first body part is located above the second body part and the first vertical part abuts against the side wall of the first body part.

[0016] The inner sidewall of the module body is provided with a set of limiting members. When the second set of fixing members and the third set of fixing members are installed into the module body together, the second body part is located above the first body part and the limiting members, and the sidewall of the first body part abuts against the sidewall of the limiting members.

[0017] In implementation, three sets of fasteners are assembled in layers. The first and third sets of fasteners have the same structure and together clamp the middle second set of fasteners. The square first body of the first set of fasteners is placed above the second set of fasteners and abuts against its first vertical part. At the same time, the limiting parts inside the module body limit the second and third sets of fasteners vertically and laterally, so that the second set of fasteners is located above the third set of fasteners and the limiting parts and abuts against each other. This structure achieves precise positioning and reliable constraint of the three sets of fasteners through symmetrical clamping and multi-layer abutment limiting, effectively preventing interlayer movement, offset and shaking, improving the rigidity and stability of the overall stacked structure, ensuring accurate terminal alignment, high assembly consistency, and the symmetrical structure facilitates mold design and production, further reducing costs and improving yield.

[0018] Both the first vertical part and the limiting member are provided with insertion holes that communicate with the second insertion channel.

[0019] The cylinder connector also includes multiple sets of terminal fixing assemblies. Each terminal fixing assembly includes a first main body and clamping parts on both sides of the first main body. The clamping part has a snap-fit ​​protrusion on the side near the fixing member, and the fixing member has second snap-fit ​​grooves on both sides. The snap-fit ​​protrusion and the second snap-fit ​​grooves engage with each other, so that the terminal fixing assembly can be detachably snapped onto the fixing member. The terminal fixing assembly clamps and fixes the second terminal component to prevent the second terminal component from loosening or shifting.

[0020] Insert the second terminal component into the corresponding channel of the fixing component, and then align the terminal fixing assembly with the fixing component for assembly. The snap-fit ​​protrusion on the clamping part engages with the second snap-fit ​​grooves on both sides of the fixing component, so that the terminal fixing assembly is securely and detachably snapped onto the fixing component. The second terminal component is clamped by the clamping parts on both sides. This structure can firmly limit the second terminal component and prevent it from loosening, shifting or even falling off during use, ensuring stable terminal contact and smooth electrical connection. At the same time, the detachable snap-fit ​​method facilitates disassembly, inspection and replacement of components. The assembly operation is simple and does not require additional tools, which can improve assembly efficiency and ensure the stability and reliability of the connector for long-term use.

[0021] The first main body includes a first straight plate portion and a first snap-fit ​​portion disposed on the first straight plate portion. The bottom of the fixing part is provided with a receiving part for accommodating the first main body. The receiving part includes a first groove for accommodating the first straight plate and a second groove connected to the first groove. The second groove is used to accommodate the first snap-fit ​​part. When the first main body is embedded in the receiving part, the bottom surface of the first main body is flush with the bottom of the fixing part. The receiving part limits and blocks the first main body, restricting the vertical displacement of the terminal fixing assembly. In conjunction with the snap-fit ​​structure of the snap-fit ​​boss and the second snap-fit ​​groove, the connection between the terminal fixing assembly and the fixing member is further strengthened.

[0022] The cylinder connector also includes a secondary locking component. The housing and / or the plug-in module are provided with a second clearance groove for accommodating the secondary locking component. The housing and the plug-in module have a snap-fit ​​structure for fastening. The secondary locking component is inserted into the second clearance groove and acts on the snap-fit ​​structure to lock the housing and the plug-in module in a secondary manner.

[0023] The secondary locking component includes an extraction part, a second main body integrally formed with the extraction part, and an elastic part. The elastic part has a protrusion, and the second main body has a clearance part. The elastic part is connected to the extraction part and is located in the clearance part. The second main body is a reference surface, and the elastic part protrudes from the reference surface. The second clearance groove is used to accommodate the second main body and the elastic part. When the elastic part is compressed, it contracts and enters the clearance part, which facilitates the installation of the secondary locking component into the second clearance groove.

[0024] During implementation, the outer shell and the plug-in module are initially fastened together using a snap-fit ​​structure. Then, the secondary locking component is aligned with the second clearance groove and pushed in. During assembly, the elastic part is compressed and retracts into the clearance part of the second main body, smoothly inserting the secondary locking component into the second clearance groove. After it is in place, the elastic part returns to its original position, making the secondary locking component securely locked in the groove and acting on the snap-fit ​​structure to achieve secondary locking between the outer shell and the plug-in module. This structure, through the integrated design of the extraction part, the second main body, and the elastic part, is compact and easy to assemble and disassemble. The elastic retraction assembly method reduces the pushing resistance and avoids damage to the components. The secondary locking setting effectively prevents the snap-fit ​​structure from accidentally loosening, eliminating the possibility of separation or power failure of the connector during use, greatly improving the connection's firmness and safety. At the same time, the protruding structure of the elastic part can achieve self-locking, preventing the secondary locking component from falling off on its own and ensuring a stable and reliable connection.

[0025] The inner wall of the outer shell is provided with a first fastening part, and the outer side of the module body of the plug-in module is provided with a third main body part. A clearance chamber is provided between the third main body part and the module body, and the clearance chamber is connected to the second clearance groove. The third main body part is provided with a first fastening hole, an isolation rib and a second fastening hole, and the isolation rib is located between the first fastening hole and the second fastening hole. The third main body part, the first fastening part and the elastic part together form a snap-fit ​​structure. When the outer shell is plugged into the plug-in module, the first fastening part is fastened to the first fastening hole. When the secondary locking component is plugged into the second clearance groove through the clearance chamber, the protrusion is fastened to the second fastening hole, and the isolation rib is located between the secondary locking component and the first fastening part.

[0026] During implementation, the outer shell and the plug-in module are connected and plugged in. The first fastening part on the inner side wall of the outer shell first fastens into the first fastening hole of the third main body, completing the initial fastening and positioning. Then, the secondary locking component is inserted into the second clearance groove through the clearance chamber. The protrusion on the elastic part then fastens with the second fastening hole, realizing secondary locking and reinforcement. During this process, the third main body, the first fastening part, and the elastic part together form a complete snap-fit ​​structure. The isolation rib separates the first fastening hole and the second fastening hole and is located between the secondary locking component and the first fastening part. This not only avoids mutual interference between components and prevents accidental unlocking, but also limits the assembly path. This structure achieves double locking through step-by-step fastening, which greatly improves the connection between the outer shell and the plug-in module and prevents accidental loosening. The clearance chamber provides smooth assembly space for the secondary locking component, and the isolation rib also enhances the structural strength, ensuring accurate snap-fit ​​engagement and stable operation, making the electrical connection of the connector more reliable and safer to use.

[0027] The cylinder connector also includes a sealing element fitted onto the outer shell. An annular groove for accommodating the sealing element is provided on the outer side of the outer shell, and the sealing element is fitted onto the outer shell through the annular groove. Multiple sets of insertion ribs are provided on the outer side of the outer shell, and the multiple sets of insertion ribs are evenly arranged along the outer peripheral wall of the outer shell. When the external connector is connected to the connector, the insertion ribs are inserted into the insertion structure of the external connector, and the inner side wall of the external connector is interference-fitted with the sealing element.

[0028] During implementation, the seal is embedded in the annular groove on the outer side of the housing. The annular groove limits the seal, preventing displacement or detachment. Then, the external connector is mated with the cylinder connector. Multiple sets of plug-in ribs evenly distributed circumferentially on the outer side of the housing first interlock with the plug-in structure of the external connector to guide and position the mating, ensuring precise assembly. Subsequently, the inner wall of the external connector forms an interference fit with the seal. This structure enables quick and precise mating between the connector and the external connector through the plug-in ribs, avoiding assembly misalignment. It also fixes the seal through the annular groove, forming a tight sealing structure with the interference fit. This effectively prevents dust and liquid from entering the connector, improving the connector's sealing performance and operational stability, and extending the connector's service life.

[0029] Both sides of the inner sidewall of the clearance cavity are provided with snap-fit ​​protrusions, and both sides of the second main body are provided with mounting parts that engage with the snap-fit ​​protrusions. The mounting parts include a second snap-fit ​​groove and a third snap-fit ​​groove arranged along the length of the second main body, and an arc-shaped guide part is provided between the second snap-fit ​​groove and the third snap-fit ​​groove. When the secondary locking component is fully inserted into the second clearance groove, the snap-fit ​​protrusion engages with the third snap-fit ​​groove. When the secondary locking component is half pulled out of the second clearance groove, the snap-fit ​​protrusion engages with the second snap-fit ​​groove. The protrusion on the elastic part retracts through the second fastening hole to the first fastening hole and pushes the first fastening part of the outer shell out from the first fastening hole, thereby realizing the separation of the outer shell from the module body.

[0030] During implementation, as the secondary locking component is inserted into the second clearance slot, the locking protrusion on the inner wall of the clearance cavity slides along the arc-shaped guide. When the secondary locking component is fully inserted, the locking protrusion engages with the third locking groove on the second main body, achieving a stable positioning of the secondary locking component. When the connector needs to be disassembled, the secondary locking component is partially pulled out, and the locking protrusion engages with the second locking groove. At this time, the protrusion on the elastic part retracts from the second fastening hole to the first fastening hole, pushing the first fastening part of the outer shell out from the first fastening hole, completing the unlocking and disassembly of the outer shell from the module body. This structure, through the cooperation of the double slots and the locking protrusion, achieves precise switching between the locked and semi-locked states. The arc-shaped guide makes the pulling operation smoother and without jamming, ensuring that the connector connection is firm in the locked state, preventing the secondary locking component from loosening and falling off, and enabling convenient unlocking without the need for tools, making disassembly and assembly more efficient. At the same time, it avoids damage to components caused by forced disassembly, improving the ease of use and structural durability of the connector.

[0031] The elastic element and the fixing element are integrally injection molded. The thickness of the elastic element is less than the wall thickness of the fixing element. The elastic element can perform elastic expansion and contraction along the first relief groove.

[0032] The first fastening part has a guide slope at its end, which is set towards the insertion direction of the outer shell to facilitate the insertion of the first fastening part into the first fastening hole.

[0033] The outer shell is provided with an annular connecting portion, which in turn has a circular portion, on which a nut or a nest is accommodated. When the connector is locked and fixed to the external support, the nut or nest increases the installation strength, effectively improving the installation strength of the connector. This structure, through the annular connecting portion and the circular portion, forms a dedicated fixed support structure, which not only provides a stable mounting point for the connector, adapting to different installation and fixing requirements, but also distributes the force during the installation and locking process, preventing damage to the connector body, eliminating loosening and displacement, ensuring that the connector is securely fixed, and meeting the requirements for long-term stable use.

[0034] The beneficial effects of this invention are as follows: This invention adopts a layered assembly and multi-locking design principle, abandoning the traditional integral structure and setting the fixing parts as multi-layered split parts. It completes the module assembly with elastic snap-fit ​​and guide limit structure, and then achieves double fixation of the outer shell and plug-in module through primary buckle and secondary locking components. Combined with sealing structure and external installation structure, it improves the practicality of the whole machine. It has strong practical value and technical advantages. It not only simplifies the mold structure, reduces development and production costs, reduces injection molding defects and improves product yield, but also flexibly adapts to different assembly requirements. The assembly process is smooth and efficient, and the positioning is accurate. It can effectively prevent parts from tilting, shifting, or loosening. The terminals are firmly clamped, and the electrical connection is stable and reliable. The double locking structure can prevent accidental loosening. The unlocking operation is convenient and labor-saving. The sealing protection is in place. The external ring connection part is equipped with nuts or nests to greatly improve the installation and fixing strength. It is suitable for a variety of installation scenarios. The overall structure is compact, durable, and has strong shock resistance. It can greatly extend the service life of the connector and meet the use requirements of harsh working conditions.

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0038] Please see Figures 1 to 15 As shown, a lever-type cylinder connector for a 24-pin terminal module includes a plug-in module 2. The plug-in module 2 includes a module body 8, multiple sets of fixing members 9 housed within the module body 8, and multiple sets of terminal units respectively disposed on the multiple sets of fixing members 9. All terminal units of the plug-in module 2 are combined to form a signal transmission terminal. The multiple sets of fixing members 9 are connected together to form a fixed module. The module body 8 is provided with a limiting snap-fit ​​structure, and the fixed module is fixed within the module body 8 by means of the limiting snap-fit ​​structure.

[0039] The lever-type cylinder connector also includes a housing 1, and a plug-in module 2 is disposed inside the housing 1. The housing 1 is provided with a first plug-in channel 4 and a first terminal component 6 located within the first plug-in channel 4. The plug-in module 2 is provided with a second plug-in channel 5 connected to the first plug-in channel 4 and a second terminal component 7 located within the second plug-in channel 5. When the housing 1 and the plug-in module 2 are plugged in, the first terminal component 6 and the second terminal component 7 form an electrical connection. The first terminal component 6 and the second terminal component 7 are combined to form a terminal group 3, and the signal transmission terminal is the second terminal component 7.

[0040] Multiple sets of fasteners 9 are stacked layer by layer. Through the limiting and snapping structure within the module body 8, each set of fasteners 9 is sequentially snapped and fixed inside the module body 8, forming a neat stacked structure. Then, the plug-in module 2 is installed inside the outer shell 1, so that the first plug-in channel 4 of the outer shell 1 and the second plug-in channel 5 of the plug-in module 2 are interconnected. After the outer shell 1 and the plug-in module 2 are plugged in, the first terminal component 6 in the first plug-in channel 4 and the second terminal component 7 in the second plug-in channel 5 precisely align, forming a stable electrical connection. The through-channel of the fastener 9 is connected to the second plug-in... The 5th channel is interconnected and can stably accommodate the second terminal component 7, preventing terminal displacement. Compared with the traditional integral connector, this structure has significant advantages. It adopts a layered snap-fit ​​fastener 9 design, which abandons the complex integral structure, greatly simplifies the mold structure, reduces mold development costs, reduces injection molding defects, improves product yield, and can flexibly adapt to the assembly requirements of different numbers of layers. The limiting snap-fit ​​structure can ensure that the multi-layer fastener 9 is assembled accurately and without skewing or offset, making the terminal docking more accurate and the electrical connection more stable and reliable. The overall assembly operation is simple and the structure is sturdy and durable.

[0041] The fixing member 9 is provided in three sets. Each set of fixing members 9 is provided with a set of elastic members 11 on both sides. The module body 8 is provided with a first snap-fit ​​groove 12 for accommodating the elastic members 11. The first snap-fit ​​groove 12 is provided in multiple sets. One set of first snap-fit ​​groove 12 cooperates with one set of elastic members 11. The first snap-fit ​​groove 12 is a limiting snap-fit ​​structure. The fixing member 9 is accommodated in the plug-in module 2 through the snap-fit ​​cooperation between the elastic members 11 and the first snap-fit ​​groove 12.

[0042] The elastic element 11 includes a cantilever connecting block 100, an extension arm 101, and a limiting block 103. One end of the cantilever connecting block 100 is connected to the fixing member 9, and the end of the cantilever connecting block 100 away from the fixing member 9 is connected to the extension arm 101. The limiting block 103 is located on the side of the extension arm 101 away from the cantilever connecting block 100 and is used to engage and limit the extension arm 101 with the first locking groove 12. The extension arm 101 can undergo elastic deformation under external force, and the free end of the extension arm 101 protrudes from the insertion end face of the fixing member 9 so that the elastic element 11 can be disassembled and assembled with the first locking groove 12 by pressing the free end.

[0043] A first clearance groove 13 is provided between the fixing member 9 and the elastic member 11. The first clearance groove 13 is used to provide deformation space for the elastic deformation of the elastic member 11. A first inclined guide surface 104 is provided on the limiting block 103. The module body 8 includes a housing part 105 and a flange 106 integrally formed with the housing part 105. The flange 106 is located at the insertion end face of the housing part 105. A guide block 107 is provided on the side of the flange 106 near the elastic member 11. A second inclined guide surface 108 is provided on the guide block 107. The first inclined guide surface 104 and the second inclined guide surface 108 match each other. When the fixing module is inserted and assembled relative to the module body 8, the limiting block 103 abuts and guides the first inclined guide surface 104 and the second inclined guide surface 108, so that the elastic member 11 elastically contracts in the first clearance groove 13, thereby realizing the snap-fit ​​fixing of the limiting block 103 and the first snap-fit ​​groove 12.

[0044] The elastic element 11 is composed of a cantilever connecting block 100, an extension arm 101, and a limiting block 103. The cantilever connecting block 100 is connected to the fixing member 9. The free end of the extension arm 101 extends out of the insertion end face of the fixing member 9. A relief groove is provided between the fixing member 9 and the elastic element 11 to provide space for elastic deformation. The limiting block 103 is provided with a first inclined guide surface 104. The shell part 105 of the module body 8 is integrally formed with a flange 106. The flange 106 is provided with a guide block 107 with a second inclined guide surface 108. The two inclined guide surfaces match and guide. When the fixed module is inserted, the elastic element 11 elastically contracts in the relief groove by abutting the guide surfaces, thereby realizing the automatic locking and fixing of the limiting block 103 and the first locking groove 12. The locking can be released by pressing the free end of the extension arm 101. The overall structure is easy to assemble, reliable in positioning, and easy to disassemble and assemble, effectively improving the assembly efficiency and structural stability of the connector.

[0045] The guide block 107 is provided with a first tilt angle 109. When the elastic member 11 is engaged with the first snap-fit ​​groove 12, the first tilt angle 109 is located on the side of the limiting block 103 away from the first inclined guide surface 104. The first tilt angle 109 is 30° to 90°, preferably 80°.

[0046] When the elastic element 11 and the first locking groove 12 are engaged, the first tilt angle 109 is located on the side of the limiting block 103 away from the first inclined guide surface 104. This can form a reliable limiting stop on the limiting block 103 to prevent the elastic element 11 from accidentally loosening. At the same time, it works with the inclined guide surface to realize insertion guidance and automatic locking, which not only ensures smooth assembly, but also improves the locking stability and anti-loosening reliability after locking.

[0047] The inner sidewall of the module body 8 is provided with multiple sets of guide ribs 15. A set of guide ribs 15 is provided between two adjacent sets of first snap-fit ​​grooves 12, and a set of first snap-fit ​​grooves 12 is provided between two adjacent sets of guide ribs 15. The guide ribs 15 extend along the assembly direction of the fastener 9 to guide and position the fastener 9 during the assembly process.

[0048] When assembling multiple sets of fasteners 9, multiple sets of guide ribs 15 extending along the assembly direction on the inner sidewall of the module body 8 are used. A first snap-fit ​​groove 12 is provided between each pair of adjacent guide ribs 15, and guide ribs 15 are also provided between adjacent first snap-fit ​​grooves 12. During the process of the fastener 9 sliding into the first snap-fit ​​groove 12, its two sides and interlayer structure are precisely guided and limited by the guide ribs 15. Specifically, each set of fasteners 9 is placed into the space between adjacent guide ribs 15, smoothly slides into and snaps into the first snap-fit ​​groove 12 along the assembly direction of the guide ribs 15. The guide ribs 15 directionally guide the assembly path of the fasteners 9 to prevent them from tilting, shifting or getting stuck during the assembly process. The beneficial effects of this structure are that the arrangement of multiple sets of guide ribs 15 creates a regular assembly guide rail, which not only significantly improves the accuracy and smoothness of the assembly of the multi-layer fastener 9, but also effectively avoids poor terminal connection caused by assembly deviation; at the same time, the guide ribs 15 and the first snap-fit ​​strip are arranged alternately to form a multi-directional limiting clamp for the multi-layer fastener 9, which enhances the overall rigidity of the stacked structure, prevents the fastener 9 from radially loosening or axially displacing during use, significantly improves the connection stability and structural reliability of the connector, and ensures the long-term stability of the electrical connection.

[0049] The first set of fixing members 9 and the third set of fixing members 9 have the same structure. The first set of fixing members 9 and the third set of fixing members 9 together clamp the second set of fixing members 9. The first set of fixing members 9 and the third set of fixing members 9 both include a first body part 111. The first body part 111 has a square structure. The second set of fixing members 9 includes a second body part 222 and a first vertical part 333 disposed on the second body part 222. When the first set of fixing members 9 and the second set of fixing members 9 are installed together in the module body 8, the first body part 111 is located above the second body part 222 and the first vertical part 333 abuts against the side wall of the first body part 111.

[0050] The inner side wall of the module body 8 is provided with a set of limiting members 444. When the second set of fixing members 9 and the third set of fixing members 9 are installed together in the module body 8, the second body part 222 is located above the first body part 111 and the limiting member 444, and the side wall of the first body part 111 abuts against the side wall of the limiting member 444.

[0051] In implementation, three sets of fasteners 9 are assembled in layers. The first and third sets of fasteners 9 have the same structure and together clamp the middle second set of fasteners 9. The square first body part 111 of the first set of fasteners 9 is placed above the second set of fasteners 9 and abuts against its first vertical part 333. At the same time, the limiting part 444 on the inner side of the module body 8 limits the second and third sets of fasteners 9 vertically and laterally, so that the second set of fasteners 9 is located above the third set of fasteners 9 and the limiting part 444 and abuts against each other for positioning. This structure achieves precise positioning and reliable constraint of the three sets of fasteners 9 through symmetrical clamping and multi-layer abutment limiting, effectively preventing interlayer movement, offset and shaking, improving the rigidity and stability of the overall stacked structure, ensuring accurate terminal alignment, high assembly consistency, and the symmetrical structure facilitates mold design and production, further reducing costs and improving yield.

[0052] Both the first vertical part 333 and the limiting member 444 are provided with insertion holes that communicate with the second insertion channel 5.

[0053] The cylinder connector also includes multiple sets of terminal fixing assemblies 16. Each terminal fixing assembly 16 includes a first main body 17 and clamping parts 18 disposed on both sides of the first main body 17. The clamping part 18 is provided with a snap-fit ​​boss 19 on the side near the fixing member 9. The fixing member 9 is provided with second snap-fit ​​grooves 41 on both sides. The snap-fit ​​boss 19 and the second snap-fit ​​grooves 41 engage with each other, so that the terminal fixing assembly 16 can be detachably snapped onto the fixing member 9. The terminal fixing assembly 16 clamps and fixes the second terminal component 7 to prevent the second terminal component 7 from loosening or shifting.

[0054] The second terminal component 7 is inserted into the corresponding channel of the fixing member 9, and then the terminal fixing assembly 16 is aligned with the fixing member 9 for assembly. The snap-fit ​​protrusion 19 on the clamping part 18 is engaged with the second snap-fit ​​groove 41 on both sides of the fixing member 9, so that the terminal fixing assembly 16 is securely and detachably snapped onto the fixing member 9. The second terminal component 7 is clamped by the clamping parts 18 on both sides. This structure can firmly limit the second terminal component 7, prevent it from loosening, shifting or even falling off during use, and ensure stable terminal contact and smooth electrical connection. At the same time, the detachable snap-fit ​​method facilitates disassembly, maintenance and replacement of components. The assembly operation is simple and does not require additional tools. It can improve assembly efficiency and ensure the stability and reliability of the connector for long-term use.

[0055] The first main body 17 includes a first straight plate 48 and a first snap-fit ​​portion 49 disposed on the first straight plate 48.

[0056] The bottom of the fixing part is provided with a receiving part for accommodating the first main body 17. The receiving part includes a first groove 51 for accommodating the first straight plate 48 and a second groove 52 connected to the first groove 51. The second groove 52 is used to accommodate the first snap-fit ​​part 49. When the first main body 17 is embedded in the receiving part, the bottom surface of the first main body 17 is flush with the bottom of the fixing part. The receiving part limits and blocks the first main body 17, restricting the vertical displacement of the terminal fixing assembly 16. In conjunction with the snap-fit ​​structure of the snap-fit ​​boss 19 and the second snap-fit ​​groove 41, the connection between the terminal fixing assembly 16 and the fixing member 9 is further strengthened.

[0057] The cylinder connector also includes a secondary locking component 21. The housing 1 and / or the plug-in module 2 are provided with a second clearance groove 22 for accommodating the secondary locking component 21. The housing 1 and the plug-in module 2 have a snap-fit ​​structure for fastening. The secondary locking component 21 is inserted into the second clearance groove 22 and acts on the snap-fit ​​structure to lock the housing 1 and the plug-in module 2 in a secondary manner.

[0058] The secondary locking component 21 includes an extraction part 23, a second main body part 24 integrally formed with the extraction part 23, and an elastic part 25. The elastic part 25 is provided with a protrusion 26, and the second main body part 24 is provided with a clearance part 27. The elastic part 25 is connected to the extraction part 23 and is located in the clearance part 27. The second main body part 24 is a reference reference surface, and the elastic part 25 protrudes out of the reference reference surface. The second clearance groove 22 is used to accommodate the second main body part 24 and the elastic part 25. The elastic part 25 is compressed and retracts into the clearance part 27, which facilitates the insertion of the secondary locking component 21 into the second clearance groove 22.

[0059] During implementation, the outer shell 1 and the plug-in module 2 are initially fastened together using a snap-fit ​​structure. Then, the secondary locking component 21 is aligned with the second clearance groove 22 and pushed in. During assembly, the elastic part 25 is compressed and retracts into the clearance part 27 of the second main body, smoothly inserting the secondary locking component 21 into the second clearance groove 22. After it is in place, the elastic part 25 resets the protrusion 26, so that the secondary locking component 21 is firmly locked in the groove and acts on the snap-fit ​​structure to achieve secondary locking between the outer shell 1 and the plug-in module 2. This structure, through the design of the extraction part 23, the second main body part 24 and the elastic part 25 being integrally formed, has a compact structure and is easy to assemble and disassemble. The elastic retraction assembly method can reduce the pushing resistance and avoid damage to the components. The secondary locking setting can effectively prevent the snap-fit ​​structure from accidentally loosening, eliminating the situation of separation or power failure of the connector during use, greatly improving the connection firmness and safety of use. At the same time, the protrusion 26 structure of the elastic part 25 can achieve self-locking, preventing the secondary locking component 21 from falling off by itself, ensuring a stable and reliable connection.

[0060] The inner wall of the outer shell 1 is provided with a first fastening part 28, and the outer side of the module body 8 of the plug-in module 2 is provided with a third main body part 29. A clearance chamber 31 is provided between the third main body part 29 and the module body 8, and the clearance chamber 31 is connected to the second clearance groove 22. The third main body part 29 is provided with a first fastening hole 32, an isolation rib 33 and a second fastening hole 34. The isolation rib 33 is located between the first fastening hole 32 and the second fastening hole 34. The third main body part 29, the first fastening part 28 and the elastic part 25 together form a snap-fit ​​structure. When the outer shell 1 is plugged into the plug-in module 2, the first fastening part 28 is fastened to the first fastening hole 32. When the secondary locking component 21 is inserted into the second clearance groove 22 through the clearance chamber 31, the protrusion 26 is fastened to the second fastening hole 34, and the isolation rib 33 is located between the secondary locking component 21 and the first fastening part 28.

[0061] During implementation, the outer shell 1 is connected to the plug-in module 2. The first fastening part 28 on the inner sidewall of the outer shell 1 first fastens into the first fastening hole 32 of the third main body 29, completing the initial fastening and positioning. Then, the secondary locking component 21 is inserted into the second clearance groove 22 through the clearance chamber 31. The protrusion 26 on the elastic part 25 then fastens with the second fastening hole 34, achieving secondary locking and reinforcement. During this process, the third main body 29, the first fastening part 28, and the elastic part 25 together form a complete snap-fit ​​structure. The isolation rib 33 separates the first fastening hole 32 from the... The second latching hole 34, located between the secondary locking component 21 and the first latching part 28, can not only avoid mutual interference between components and prevent accidental unlocking, but also limit the assembly path. This structure achieves double locking through step-by-step latching, which greatly improves the connection between the outer shell 1 and the plug-in module 2 and prevents accidental loosening. The setting of the clearance chamber 31 provides a smooth assembly space for the secondary locking component 21, and the isolation rib 33 can also enhance the structural strength, ensure accurate latching and stable operation, make the electrical connection of the connector more reliable, and improve the safety of use.

[0062] The cylinder connector also includes a sealing element 35 sleeved on the outer shell 1. The outer shell 1 has an annular groove 36 for accommodating the sealing element 35, and the sealing element 35 is sleeved on the outer shell 1 through the annular groove 36. The outer shell 1 has multiple sets of insertion ribs 37, which are evenly arranged along the outer peripheral wall of the outer shell 1. When the external connector is connected to the connector, the insertion ribs 37 are inserted into the insertion structure of the external connector, and the inner sidewall of the external connector is interference-fitted with the sealing element 35.

[0063] In implementation, the seal 35 is embedded in the annular groove 36 on the outer side of the housing 1. The annular groove 36 limits the seal 35 to prevent displacement or detachment. Then, the external connector is mated with the cylinder connector. Multiple sets of plug-in ribs 37, evenly arranged circumferentially on the outer side of the housing 1, first plug into the plug-in structure of the external connector to achieve docking guidance and positioning, ensuring accurate assembly. Subsequently, the inner wall of the external connector forms an interference fit with the seal 35. This structure can achieve quick and accurate docking between the connector and the external connector through the plug-in ribs 37, avoiding assembly misalignment, and can also fix the seal 35 through the annular groove 36. Combined with the interference fit, a tight sealing structure is formed, effectively preventing dust and liquid from entering the connector, improving the sealing and protection performance and operational stability of the connector, and extending the service life of the connector.

[0064] Both sides of the inner sidewall of the clearance chamber 31 are provided with snap-fit ​​protrusions 38. Both sides of the second main body 24 are provided with mounting portions 39 that engage with the snap-fit ​​protrusions 38. The mounting portions 39 include a second snap-fit ​​groove 41 and a third snap-fit ​​groove 42 arranged along the length of the second main body 24. An arc-shaped guide portion 43 is provided between the second snap-fit ​​groove 41 and the third snap-fit ​​groove 42. When the secondary locking component 21 is fully inserted into the second clearance groove 22, the snap-fit ​​protrusion 38 engages with the third snap-fit ​​groove 42. When the secondary locking component 21 is half pulled out of the second clearance groove 22, the snap-fit ​​protrusion 38 engages with the second snap-fit ​​groove 41. The protrusion 26 on the elastic part 25 retracts to the first fastening hole 32 through the second fastening hole 34 and pushes out the first fastening part 28 of the outer shell 1 from the first fastening hole 32, thereby realizing the separation of the outer shell 1 from the module body 8.

[0065] During implementation, as the secondary locking component 21 is inserted into the second clearance groove 22, the locking protrusion 38 on the inner wall of the clearance chamber 31 slides along the arc-shaped guide portion 43. When the secondary locking component 21 is fully inserted, the locking protrusion 38 engages with the third locking groove 42 on the second main body 24, achieving a stable positioning of the secondary locking component 21. When the connector needs to be disassembled, the secondary locking component 21 is partially pulled out, and the locking protrusion 38 engages with the second locking groove 41. At this time, the protrusion 26 on the elastic portion 25 retracts from the second fastening hole 34 to the first fastening hole 32. The first fastening part 28 of the outer shell 1 is pushed out from the first fastening hole 32, thus unlocking and disengaging the outer shell 1 from the module body 8. This structure achieves precise switching between the locked and semi-locked states through the double slots and the snap-fit ​​protrusion 38. The arc-shaped guide part 43 makes the pull-out operation smoother and without jamming. It can ensure that the connector is firmly connected in the locked state, prevent the secondary locking part 21 from loosening and falling off, and achieve convenient unlocking without the need for tools. The disassembly and assembly operations are more efficient, and at the same time, it can avoid damage to the parts caused by forced disassembly, thus improving the ease of use and structural durability of the connector.

[0066] The elastic element 11 and the fixing element 9 are integrally injection molded. The thickness of the elastic element 11 is less than the wall thickness of the fixing element 9. The elastic element 11 can perform elastic expansion and contraction along the first relief groove 13.

[0067] The first fastening part 28 has a guide slope 44 at its end, which is arranged toward the insertion direction of the outer shell 1, so that the first fastening part 28 can be inserted into the first fastening hole 32.

[0068] The outer casing 1 is provided with an annular connecting portion 45, and the annular connecting portion 45 is provided with a circular annular portion 46, on which a nut 47 or a nest is accommodated. When the connector is locked and fixed to the external carrier, the nut 47 or the nest increases the installation strength and effectively improves the installation strength of the connector. This structure forms a dedicated fixed support structure through the annular connecting portion 45 and the circular annular portion 46, which can not only provide a stable installation point for the connector and adapt to different installation and fixing requirements, but also distribute the force during the installation and locking process, prevent damage to the connector body, eliminate loosening and displacement, ensure that the connector is firmly fixed, and meet the requirements of long-term stable use.
