Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, and in particular to an integrated connector. Background Technology

[0002] With the rapid development of the automotive industry, people's requirements for automotive comfort, safety, economy and intelligence are constantly increasing, making automotive connector circuits more and more complex and the number of connectors used is increasing day by day. On average, a car uses about 600-1000 electronic connectors. If the connector structure can be simplified, unnecessary installation time and packaging costs can be saved.

[0003] Existing connectors on the market that separate the body and the shell require the body and shell to be packaged and shipped separately. After the terminals are installed on the body, the shell is assembled with the body, and the terminals are then hooked on the shell through the bosses on the shell. When removing the terminals, the shell must be separated from the body first, and then the terminals must be removed using a terminal tool. The installation process is cumbersome, and there is some shaking between the body and the shell, which may lead to electrical connection failure. Summary of the Invention

[0004] To address the shortcomings of the aforementioned background technology, this utility model proposes an integrated non-waterproof connector, which solves the problems of cumbersome assembly and large terminal wobbling in the existing split connectors.

[0005] The technical solution of this utility model is implemented as follows: An integrated non-waterproof connector includes a socket sleeve, an assist rod, a TPA structure, and an adapter interface. The assist rod is rotatably connected to the socket sleeve. A cantilever hook mechanism is provided at the end of the assist rod, which engages with a first mounting platform located at the front end of the socket sleeve. Three-point limiting structures for limiting the assist rod are provided on both sides of the socket sleeve. A mounting square groove is provided at the rear end of the socket sleeve, into which the TPA structure is inserted. A pre-installation positioning mechanism is provided between the TPA structure and the socket sleeve. The socket sleeve engages with the adapter interface, and a toothed pushing mechanism is provided between the socket sleeve and the assist rod. This utility model socket end is a socket sleeve assembly with a TPA and an assist rod, fulfilling the functions of preventing incorrect installation, preventing terminal displacement, and facilitating connector mating. It solves the problems of cumbersome assembly and large terminal wobbling associated with separate connectors, while also reducing packaging costs.

[0006] Further optimized, the socket sleeve has pivots on both sides, and the two arms of the assist rod have pivot grooves that mate with the pivots; the ends of the pivots have U-shaped grooves and guardrail blocks that limit the movement of the pivot grooves. The guardrail blocks at the front end of the pivots prevent the assist rod from detaching, ensuring the stability of the connection.

[0007] Further optimization includes several terminal holes inside the socket sleeve for installing terminals, with terminal mounting brackets inside the terminal holes, and the spring-loaded portion of the terminal hooking onto the terminal mounting brackets; an unlocking hole is provided on the front end face of the socket sleeve. When removing the terminal, a tool is needed to push it from its final position to the pre-installed position through the unlocking hole of the sleeve, and then the terminal can be removed with the help of a terminal removal tool; this achieves convenient disassembly. The front end of the socket sleeve has a first anti-misalignment rib, and the rear end of the socket sleeve has a second anti-misalignment rib; the adapter interface has a first anti-misalignment groove that matches the first anti-misalignment rib and a second anti-misalignment groove that matches the second anti-misalignment rib; the anti-misalignment rib groove intervenes to guide during the initial insertion, ensuring precise alignment of the sleeve and the adapter interface, creating ideal initial conditions for the subsequent meshing of the toothed push mechanism, and preventing the toothed block and rack from jamming or breaking due to misalignment.

[0008] Further optimized, the assist rod is a U-shaped component, with a cantilever hook mechanism located on its crossbeam. The cantilever hook mechanism includes a cantilever and a first hook located at the lower part of the cantilever, which engages with a first mounting plate. This ensures reliable locking of the assist rod and prevents accidental detachment during transportation and use.

[0009] Further optimized, the toothed booster mechanism includes toothed blocks disposed at the ends of the two arms of the booster rod and racks disposed on both sides inside the adapter interface. The teeth of the toothed blocks can mesh with the racks. The ends of the two arms of the booster rod are also provided with first springs, and each outer arm of the first spring is provided with a pressing protrusion. The inner side of the toothed blocks and the corresponding teeth are provided with baffles. After the toothed blocks and racks of the toothed booster mechanism mesh, they form a reverse self-locking mechanism, so that the connector will not accidentally loosen even under external vibration or pulling, and the connection reliability is significantly improved.

[0010] Further optimization reveals that the three-point limiting structure includes a slot block, a side wall hanging point, and a limiting side platform set on the side wall of the socket sleeve. When the assist rod is in the sleeve installation position, the front end (a) of the assist rod mates with the limiting side platform, the rear end (b) of the assist rod corresponds to the side wall hanging point, and the first spring fin engages with the slot block. This ensures the stability of the assist rod when it is in the sleeve installation position.

[0011] Further optimization involves designing the slot block as an L-shaped block. A second mounting platform is located on the side of the slot block furthest from the socket sheath. When the assist rod is in the sheath mounting position, the first spring-loaded fin engages with the second mounting platform. Unlocking requires only pressing the outer pressing protrusions of both arms, causing the spring-loaded fins to deform elastically and quickly disengage, achieving "one-click unlocking" with a short operation path and fast response.

[0012] Further optimized, the pre-installation positioning mechanism includes a third mounting platform at the entrance of the installation slot and a first mounting point and a second mounting point on the TPA structure. The first mounting point and the second mounting point are arranged in parallel. When the first mounting point passes the third mounting platform, the TPA structure is in the pre-installation position; when the second mounting point passes the third mounting platform, the TPA structure is in the final position.

[0013] Further optimization shows that the TPA structure is symmetrical both vertically and horizontally. The TPA structure includes a flat plate part and an end plate part. The flat plate part has several limiting holes adapted to the terminals, and a platform is left between two adjacent limiting holes. When the TPA structure is in the final position, the housing part of the terminal is attached to the platform.

[0014] The assembly and disassembly process of the aforementioned integrated non-waterproof connector is as follows: The assembly process of the assist rod and the socket sheath is as follows: Press the rotating grooves on both sides of the assist rod onto the rotating shafts on both sides of the socket sheath. The guard block at the front end of the sheath's rotating shaft prevents the assist rod from detaching. Rotate the assist rod so that its hook engages with the first mounting platform. Push one end of the TPA structure into the square mounting slot until a slight "click" is heard. At this point, the first mounting point of the TPA structure passes through the third mounting platform and reaches the pre-installed position. This is the connector's shipping state. The connector mating process is as follows: Step 1: Install the crimped terminals into the terminal holes of the socket sheath. The spring-loaded part of the terminal is hooked onto the terminal mounting platform. After all terminals are installed in place, continue to push the TPA structure forward. You will hear a slight "click" sound. The second hook point of the TPA structure passes through the third mounting platform. At this time, the TPA structure is in its final position. The housing part of the terminal is hooked onto the platform, completing the secondary locking function of the terminal.

[0015] Step 2: Press down on the cantilever of the assist rod to separate the first hook of the assist rod from the first hanging platform. At the same time, rotate the assist rod so that its first spring fin is engaged in the slot block of the socket sleeve. At this time, the front end a side of the assist rod is close to the limiting side platform, and the rear end b side of the assist rod corresponds to the side wall hanging point. The side wall hanging point, the limiting side platform, and the slot block together restrict the rotation of the assist rod. At this time, the assist rod is in the sleeve installation position.

[0016] Step 3: Align the socket cover with the adapter interface. The pressing protrusion of the first spring wing contacts the top of the adapter interface. Continue to install downwards. The pressing protrusion is squeezed by the interface wall and deforms inwards. The first spring wing separates from the second mounting plate of the cover slot. Then, rotate the booster rod to make the teeth of its toothed block mesh with the rack and move forward, driving the socket cover towards the adapter interface until it is installed in place.

[0017] The connector disassembly process is as follows: Rotate the lever to the sheath mounting position. During this process, the teeth of the toothed block mesh with the rack and move in the opposite direction, causing the socket sheath to move away from the adapter interface until it is separated from the socket sheath.

[0018] When removing the terminal, a tool is needed to push the TPA structure from the final position to the pre-installed position through the unlocking hole on the front side of the socket sleeve, and then the terminal can be removed with the help of a terminal removal tool.

[0019] This invention, while meeting the requirements for connector use, integrates the outer shell and main body into a single receptacle sleeve. It incorporates a pre-installed clip structure, significantly improving connector assembly and disassembly efficiency. The clips are shipped pre-installed in the sleeve's pre-installed position. After the terminal is installed on the main body, pushing the clips to their final position enables secondary terminal attachment. For terminal removal, the clips are first moved from the final position to the pre-installed position, and then a terminal tool is used to remove the terminal. Integrating multiple functional structures into a single sleeve reduces the number of parts and optimizes space utilization.

[0020] The beneficial effects of this utility model are as follows: As an optimized solution for a socket sleeve with a separate main body and outer shell, this utility model is a socket sleeve assembly with a TPA structure and an assist rod, which meets the functions of preventing incorrect installation, preventing terminal displacement and connector mating. It solves the problems of complicated assembly and large terminal shaking of split connectors, while reducing packaging costs and has certain promotional value.

[0021] The advantages of this utility model are as follows: Modular plug-in structure: The TPA, assist rod, and adapter interface all adopt plug-in / click-in methods, eliminating the need for additional fasteners and improving assembly efficiency. Strong terminal holding force: A secondary locking mechanism ensures that the terminals are fully in place, preventing terminal retraction and poor contact; a pre-installed positioning mechanism enables pre-installation of the TPA to prevent errors, avoiding omissions and incorrect installations, and improving the consistency of assembly quality. High connection reliability: A three-point limiting structure forms a triangular stable constraint on the assist rod, effectively preventing wobbling and over-extension, and ensuring accurate insertion posture; a cantilever hook + first mounting platform achieves reliable locking of the assist rod, preventing accidental disengagement during transportation and use. Convenient and labor-saving operation: The toothed assist mechanism significantly reduces insertion and extraction force and improves operating comfort through lever principle and progressive tooth meshing. Compact and economical structure: The integrated design integrates multiple functional structures into a single sheath, reducing the number of parts and optimizing space utilization. This invention achieves an effective combination of low operating force, high reliability and quick maintenance, and is especially suitable for scenarios that require frequent plugging and unplugging, high vibration environments (such as new energy vehicle battery packs, industrial automation equipment) or have strict requirements for operator ergonomics.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, such as Figure 1As shown, an integrated non-waterproof connector includes a socket sleeve 1, an assist rod 2, a TPA structure 3, and an adapter interface 4. The assist rod 2 is rotatably connected to the socket sleeve 1, and the connection between the assist rod and the socket sleeve 1 is detachable. The end of the assist rod 2 is provided with a cantilever hook mechanism, which engages with a first mounting platform 1-9 located at the front end of the socket sleeve 1. The engagement between the assist rod and the socket sleeve 1 is achieved through the engagement of the cantilever hook mechanism with the first mounting platform 1-9. The socket sleeve 1 has three-point limiting structures on both sides for limiting the position of the assist rod 2. These three-point limiting structures limit the assist rod at three points in the sleeve mounting position, forming a triangular stable constraint on the assist rod, effectively preventing wobbling and over-positioning, and ensuring accurate mating posture. The socket sleeve 1 has a mounting groove 1-7 at its rear end. The TPA structure 3 is inserted into the mounting groove 1-7, and a pre-installation positioning mechanism is provided between the TPA structure 3 and the socket sleeve 1. The pre-installation positioning mechanism allows the TPA structure to be adjusted between the pre-installation position and the final position. The socket sleeve 1 is inserted into the adapter interface 4, and a toothed push mechanism is provided between the socket sleeve 1 and the push rod 2. The toothed push mechanism significantly reduces the insertion and extraction force and improves the operating comfort through the lever principle and progressive tooth meshing. This utility model, while meeting the requirements of connector use, makes the outer shell and the main body into one piece and adds a TPA structure with a pre-installation position, which can greatly improve the efficiency of connector assembly and disassembly. The TPA structure is shipped with the pre-installation position installed on the sleeve. After the terminal is installed on the main body, the TPA structure is pushed to the final position to achieve secondary connection of the terminal. When the terminal is disassembled, the TPA structure is first adjusted from the final position to the pre-installation position, and then the terminal is removed using a terminal tool. This simplifies the assembly and disassembly process while ensuring the stability of the insertion.

[0026] Example 2, as Figure 2 As shown, an integrated non-waterproof connector is further optimized based on Embodiment 1. In this embodiment, the socket sleeve 1 has rotating shafts 1-5 on both sides, symmetrically arranged. The two arms of the assist rod 2 have rotating shaft grooves 2-1 that cooperate with the rotating shafts 1-5. The rotation of the assist rod is achieved through the cooperation of the rotating shaft grooves and the rotating shafts. The end of the rotating shaft 1-5 has a U-shaped groove and a guard block 1-8 that limits the rotation shaft groove 2-1. The U-shaped groove facilitates the insertion and cooperation of the rotating shaft groove and the rotating shaft, and also facilitates disassembly and assembly. The guard block 1-8 can prevent the assist rod from disengaging, enhance the vibration and impact resistance of the rotating mechanism, and improve the long-term reliability.

[0027] In this preferred embodiment, the socket sleeve 1 has several terminal holes 1-13 for installing terminals 5. The integrated terminal holes support multi-channel signal / power transmission, resulting in a compact structure and high space utilization. Terminal mounting platforms 1-11 are provided within the terminal holes 1-13, and the spring-loaded fins 52 of the terminals 5 are attached to these platforms. When the terminal is inserted, the spring-loaded fins deform elastically and automatically spring back to the mounting platform after reaching the correct position, achieving "plug and lock" and preventing the terminals from retracting due to external force or vibration. The mounting platforms provide primary retention, and the TPA structure provides secondary locking, forming a double guarantee and significantly enhancing the terminal holding force. Unlocking holes 1-12 are provided on the front surface of the socket sleeve 1. When removing the terminals, a tool is needed to push them from their final position to the pre-installed position through the unlocking hole, and then the terminals can be removed using a terminal removal tool, improving the ease of disassembly. The rotation mechanism, limiting mechanism, and terminal holding mechanism are all integrated into the sleeve body, resulting in fewer parts, lower mold costs, and suitability for mass production. The front end of the socket sleeve 1 is provided with a first anti-misalignment rib 1-1, and the rear end of the socket sleeve 1 is provided with a second anti-misalignment rib 1-2; the adapter interface 4 is provided with a first anti-misalignment groove 4-1 that matches the first anti-misalignment rib 1-1 and a second anti-misalignment groove 4-2 that matches the second anti-misalignment rib 1-2. The two anti-misalignment ribs (first and second) must be aligned with the corresponding anti-misalignment grooves (first and second) simultaneously before insertion, forming a two-level verification mechanism. Even if the connectors are symmetrical or similar in shape, it can ensure a unique correct mating direction, completely eliminating the risk of 180° reverse insertion or misaligned mating. The anti-misalignment rib groove intervenes to guide at the initial stage of mating, ensuring that the posture of the sleeve and the adapter interface is precisely aligned, creating ideal initial conditions for the subsequent meshing of the toothed push mechanism, and avoiding jamming or tooth breakage of the toothed block and rack due to misalignment. The adapter interface 4 is provided with a small plug-in terminal 4-5 that matches the terminal and a positioning plate 4-3 that mates with the positioning holes provided in the socket sleeve 1 and the TPA structure; such as Figure 5 As shown.

[0028] In this embodiment, as a preferred solution, such as Figure 3 As shown, the assist rod 2 is a U-shaped component. The integrated U-shaped structure allows the operating force to be evenly transmitted to the two rotating shafts through the crossbeam, avoiding stress concentration on one side and extending service life. The cantilever hook mechanism is set in its crossbeam. The cantilever hook mechanism includes a cantilever 2-3 and a first hook 2-5 set in the lower part of the cantilever 2-3. The first hook 2-5 is engaged with the first hanging platform 1-9. The cantilever hook + the first hanging platform: realizes the reliable locking of the assist rod and prevents accidental detachment during transportation and use.

[0029] This embodiment, as one implementation method, includes a toothed booster mechanism comprising toothed blocks 2-2 disposed at the ends of the two arms of the booster rod 2 and racks 4-4 disposed on both sides inside the adapter interface 4. The teeth on the toothed blocks act as gears, and the teeth of the toothed blocks 2-2 can mesh with the racks 4-4. The rotation of the booster rod drives the toothed blocks to rotate relative to the racks, thereby realizing the relative movement between the socket sheath and the adapter interface, facilitating disassembly and assembly. In this embodiment, the ends of the two arms of the booster rod 2 are also provided with first springs 2-6, and each outer arm of the first spring 2-6 is provided with a pressing protrusion 2-4. The inner side of the toothed blocks 2-2 and the corresponding teeth are provided with baffles 2-7. The baffles make the tooth grooves of the toothed blocks 2-2 form a blind hole-like structure, improving the accuracy of meshing with the racks. When the socket sleeve 1 is inserted into the adapter interface 4, the pressing protrusion 2-4 of the first spring wing 2-6 first contacts the top of the adapter interface 4, and then continues to be installed downwards. The pressing protrusion 2-4 is squeezed by the interface wall and deforms inwards, forming an inward-pointing shape. The first spring wing 2-6 separates from the second mounting platform 1-3-1 of the sleeve slot 1-3, unlocking the rotating assist rod 2. In this embodiment, the toothed push mechanism forms a reverse self-locking after the toothed block and the rack mesh, so that the connector will not accidentally loosen even under external vibration or pulling, and the connection reliability is significantly improved.

[0030] Example 3: An integrated non-waterproof connector, further optimized from Example 2. In this example, the three-point limiting structure includes a slot block 1-3, a side wall hanging point 1-4, and a limiting side platform 1-6 disposed on the side wall of the socket sleeve 1. The slot block 1-3, side wall hanging point 1-4, and limiting side platform 1-6 are distributed around the rotating shaft. When the assist rod 2 is in the sleeve mounting position, the front end a-side of the assist rod 2 mates with the limiting side platform 1-6, the rear end b-side of the assist rod 2 corresponds to the side wall hanging point 1-4, and the first spring fin 2-6 engages with the slot block 1-3. The slot block, side wall hanging point, and limiting side platform form a spatial triangular positioning, constraining the assist rod from three different directions to ensure it is in a uniquely defined "sleeve mounting position," eliminating wobbling and misalignment. Specifically, the slot block 1-3 is an L-shaped block. A second mounting platform 1-3-1 is located on the side of the slot block 1-3 furthest from the socket sleeve 1. When the assist rod 2 is in the sleeve mounting position, the first spring fin 2-6 engages with the second mounting platform 1-3-1. The second mounting platform is located inside the L-shaped block, on the side furthest from the sleeve, forming a "recessed" lock. The first spring fin needs to deform elastically to engage or disengage, effectively preventing accidental unlocking of the assist rod due to transportation vibration, impact, or accidental contact. The L-shaped block and the second mounting platform can be integrally molded with the socket sleeve, resulting in a small number of parts.

[0031] As a preferred option, such as Figure 4As shown, the pre-installation positioning mechanism includes a third mounting platform 1-10 located at the entrance of the installation slot 1-7 and a first mounting point 3-1 and a second mounting point 3-2 located on the TPA structure 3. The first mounting point 3-1 and the second mounting point 3-2 are arranged in parallel. When the first mounting point 3-1 passes the third mounting platform 1-10, the TPA structure 3 is in the pre-installation position; when the second mounting point 3-2 passes the third mounting platform 1-10, the TPA structure 3 is in the final position. After the first mounting point passes the third mounting platform, the TPA structure is securely and temporarily fixed to the entrance of the installation slot, forming a "TPA-shelter" sub-assembly. This sub-assembly can be transported and put into operation independently, avoiding the TPA from being scattered and lost, and significantly reducing the main line assembly time and the complexity of parts management. After the second mounting point passes the third mounting platform, the TPA is fully pushed into the final position, and the terminal secondary locking function takes effect. The two-step operation is clear and ergonomic, reducing operator fatigue. The first attachment point provides primary retention, while the second attachment point provides secondary locking, ensuring reliable holding force even after multiple disassemblies and reassemblies. The dual attachment points can be integrally injection molded with the TPA body, resulting in high component integration and eliminating the need for subsequent assembly, making it suitable for high-volume, low-cost production.

[0032] In this embodiment, the TPA structure 3 is symmetrical both vertically and horizontally, allowing it to be installed normally even after a 180° rotation. The TPA structure 3 includes a flat plate 3-4 and an end plate 3-5. The flat plate 3-4 has several limiting holes 3-6 that fit the terminals 5, with a platform 3-3 between adjacent limiting holes 3-6. When the TPA structure 3 is in its final position, the housing 51 of the terminals 5 is attached to the platform 3-3. The flat plate is reinforced with a flat plate structure, providing high bending stiffness and preventing deformation or warping after being pushed into the square groove, ensuring precise alignment between the limiting holes and the terminals and maintaining a long-term locking function. The end plate provides axial support to prevent excessive pushing of the TPA and provides end support to the flat plate, preventing cantilever deformation. The flat plate, end plate, limiting holes, and platform can be injection molded in a single process, resulting in high component integration and eliminating the need for subsequent processing or assembly, leading to significant cost advantages in mass production. The TPA design achieves three core functions—high-strength secondary locking, foolproof assembly, and rapid maintenance—through a minimalist symmetrical flat plate structure. It is a key technological guarantee for connectors to achieve "zero failure" in harsh vibration environments (such as around automobile chassis).

[0033] The assembly and disassembly process of the integrated non-waterproof connector is as follows; the assembly process of the assist rod 2 and the socket sleeve 1 is as follows: Press the rotating shaft grooves on both sides of the assist rod 2 onto the rotating shafts 1-5 on both sides of the socket sleeve 1. The guardrail block 1-8 at the front end of the rotating shaft 1-5 of the sleeve prevents the assist rod 2 from detaching. Rotate the assist rod 2 clockwise so that its hook 2-5 is hooked onto the first hanging platform 1-9. Figure 6As shown, push one end of the TPA structure 3 into the square mounting slot 1-7 until a slight "click" is heard. At this point, the first mounting point 3-1 of the TPA structure 3 passes through the third mounting platform 1-10 and reaches the pre-installation position, indicating that the connector is in the shipping state. Figure 7 As shown.

[0034] The connector mating process is as follows: Step 1: Install the crimped terminal 5 into the terminal hole 1-13 of the socket sleeve 1. The spring fin 52 of terminal 5 is hooked onto the terminal holder 1-11, as shown. Figure 8 As shown, after all terminals are installed in place, continue to push TPA structure 3 forward until a slight "click" is heard. The second hanging point 3-2 of TPA structure 3 passes through the third hanging platform 1-10. At this time, TPA structure 3 is in its final position. The housing part 51 of terminal 5 is hung on the platform 3-3, completing the secondary locking function of the terminal.

[0035] Step 2: Press down on the cantilever 2-3 of the assist rod 2 to separate the first hook 2-5 from the first mounting plate 1-9. Simultaneously, rotate the assist rod 2 counterclockwise so that its first spring fin 2-6 engages with the slot block 1-3 of the socket sleeve 1. At this time, the front end a-side of the assist rod 2 is pressed against the limiting side plate 1-6, and the rear end b-side of the assist rod 2 corresponds to the side wall hanging point 1-4. The side wall hanging point 1-4, the limiting side plate 1-6, and the slot block 1-3 together restrict the rotation of the assist rod 2. At this time, the assist rod 2 is in the sleeve installation position, as shown. Figure 10 As shown.

[0036] Step 3: Align the second anti-misalignment rib 1-2 of the socket sleeve 1 with the second anti-misalignment groove 4-2 of the adapter interface 4, and align the first anti-misalignment rib 1-1 with the first anti-misalignment groove 4-1. Align the socket sleeve 1 with the adapter interface 4. The pressing protrusion 2-4 of the first spring wing 2-6 first contacts the top of the adapter interface 4, and then continues downwards. The pressing protrusion 2-4 is squeezed by the interface wall and deforms inwards. The first spring wing 2-6 separates from the second mounting bracket 1-3-1 of the sleeve slot 1-3. Figure 11 As shown, the booster rod 2 is then rotated clockwise so that the teeth of its toothed block 2-2 engage with the rack 4-4 and move in the forward direction, driving the socket sleeve 1 toward the adapter interface 4 until it is installed in place.

[0037] The connector disassembly process is the same as step two of the installation process, as follows: Rotate the assist rod 2 to the sheath mounting position. During this process, the teeth of the toothed block 2-2 mesh with the rack 4-4 and move in the opposite direction, causing the socket sheath 1 to move away from the adapter interface 4 until it is separated from the socket sheath 1.

[0038] When removing the terminal, a tool is needed to push the TPA structure 3 from the final position to the pre-installed position through the unlocking holes 1-12 on the front side of the socket sleeve 1, and then the terminal can be removed with the help of the terminal removal tool.

[0039] This invention, while meeting the requirements for connector use, integrates the outer shell and the main body into a single unit to form a socket sleeve. The socket sleeve incorporates a TPA structure with a pre-installed position, which greatly improves the efficiency of connector assembly and disassembly. The TPA structure is shipped with the pre-installed position installed in the sleeve. After the terminal is installed on the main body, the TPA structure is pushed to the final position to achieve secondary connection of the terminal. When disassembling the terminal, the TPA structure is first moved from the final position to the pre-installed position, and then the terminal is removed using a terminal tool. This achieves quick and non-destructive assembly and disassembly, ensuring the electrical connection stability of the connector.
