[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following is for reference. Figures 1-7A vehicle-mounted female connector 100 according to an embodiment of the present invention is described, wherein the vehicle includes a vehicle-mounted male connector 200, characterized in that the vehicle-mounted female connector 100 comprises:

[0038] The vehicle-mounted female connector 100 has a first limiting structure 10, which is used to engage with the vehicle-mounted male connector 200. When the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 are engaged, the first limiting structure 10 is adapted to engage with the second limiting structure 201 of the vehicle-mounted male connector 200 to fix the relative positions of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 along the insertion direction of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200.

[0039] The vehicle-mounted female connector 100 and the vehicle-mounted male connector 200, after being inserted and mated, jointly define the connector. The vehicle-mounted female connector 100 has a first limiting structure 10, which is used to insert and mat with the vehicle-mounted male connector 200. When the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 are inserted and mated, the first limiting structure 10 is adapted to engage with the second limiting structure 201 of the vehicle-mounted male connector 200 to fix the relative positions of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 along the insertion direction. This effectively prevents the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 from moving relative to each other along the insertion direction after insertion, ensuring a stable connection and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection and the stability of signal and power transmission.

[0040] The limiting cooperation between the first limiting structure 10 and the second limiting structure 201 helps achieve precise positioning during the insertion process, enabling the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 to accurately align. This reduces problems such as poor contact and signal interference caused by insertion deviations, improving connection quality and performance. During vehicle operation, various complex road conditions and vibration environments are encountered. The limiting cooperation between the first limiting structure 10 and the second limiting structure 201 enhances the connector's overall resistance to vibration and impact, reducing the risk of damage to internal components due to vibration, extending the connector's lifespan, and ensuring the normal operation of the vehicle's electrical system. Clear limiting allows operators to quickly and accurately complete the insertion operation during installation, reducing installation time and difficulty. Simultaneously, it facilitates the determination of whether the connector is in the correct connection state during maintenance, improving maintenance efficiency.

[0041] Furthermore, the first limiting structure 10 and the second limiting structure 201 are a paired limiting structure. For example, the first limiting structure 10 can be a boss, and the second limiting structure 201 can be a corresponding groove. The shape and size of the boss and the groove match, and the limiting is achieved by the boss embedding into the groove, preventing the vehicle female connector 100 and the vehicle male connector 200 from moving along the insertion direction after insertion. Alternatively, the first limiting structure 10 can be a spring-loaded snap or spring, and the second limiting structure 201 can be a corresponding slot or hole. During insertion, the spring is engaged in the slot, and the limiting is achieved by the elastic force, which also has an anti-dislodgement function. Alternatively, one of the first limiting structure 10 and the second limiting structure 201 can be an external thread and the other an internal thread, and the limiting is achieved by the thread engagement. However, this utility model is not limited to this. The first limiting structure 10 and the second limiting structure 201 can also be constructed as other types of limiting structures, as long as the first limiting structure 10 and the second limiting structure 201 limit each other to fix the relative positions of the vehicle female connector 100 and the vehicle male connector 200 along the insertion direction of the vehicle female connector 100 and the vehicle male connector 200.

[0042] According to an embodiment of the present invention, the vehicle-mounted female connector 100 for vehicles, by setting a first limiting structure 10 and a second limiting structure 201 of the vehicle-mounted male connector 200 for limiting cooperation, fixes the relative positions of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 along the insertion direction of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200. This effectively prevents the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 from moving relative to each other along the insertion direction after insertion, ensuring a stable connection between the two and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection, the stability of signal and power transmission, and also enhances the overall resistance of the connector to vibration and impact, reduces the risk of damage to internal components of the connector due to vibration, extends the service life of the connector, and ensures the normal operation of the vehicle's electrical system.

[0043] According to some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the vehicle-mounted female connector 100 includes:

[0044] Connector body 20, which is used to mate with vehicle-mounted male connector 200;

[0045] A pull rod structure 30 is rotatably disposed on the connector body 20 about a first direction. The pull rod structure 30 is fixedly provided with a first limiting structure 10 to drive the first limiting structure 10 to rotate synchronously. The pull rod structure 30 has a first position and a second position. When the vehicle female connector 100 is not plugged into the vehicle male connector 200, the pull rod structure 30 is located in the first position. When the vehicle female connector 100 and the vehicle male connector 200 are plugged into each other, the pull rod structure 30 is located in the second position, and the first limiting structure 10 is adapted to be limited and engaged with the second limiting structure 201.

[0046] Among them, such as Figure 1 As shown, the first direction is the X direction. The connector body 20 includes a housing 101 and a terminal block 104. The terminal block 104 is installed inside the housing 101. The terminal block 104 of the connector body 20 is used to plug and cooperate with the vehicle male connector 200 to realize the electrical connection between the vehicle female connector 100 and the vehicle male connector 200.

[0047] The pull rod structure 30 is rotatably mounted on the connector body 20 in a first direction, allowing the operator to control the position of the pull rod structure 30 through simple rotational movements, thereby completing the insertion and limiting operations. The pull rod structure 30 is fixedly provided with a first limiting structure 10 to drive the first limiting structure 10 to rotate synchronously. The first limiting structure 10 and the pull rod structure 30 can be integrally formed, or the first limiting structure 10 and the pull rod structure 30 can be fixedly connected by adhesive. However, this utility model is not limited to this. The first limiting structure 10 and the pull rod structure 30 can also be connected in other ways, as long as the pull rod structure 30 is fixedly provided with the first limiting structure 10.

[0048] The pull rod structure 30 has a first position and a second position, driving the first limiting structure 10 to rotate synchronously. This allows the position of the first limiting structure 10 to be changed. When the vehicle-mounted female connector 100 is not plugged into the vehicle-mounted male connector 200, the pull rod structure 30 is in the first position. In this position, the first limiting structure 10 does not engage with the second limiting structure 201, preventing damage to the first limiting structure 10 due to misoperation when not plugged in. When the vehicle-mounted female connector 100 and vehicle-mounted male connector 200 are plugged into each other, rotating the pull rod structure 30 to the second position allows the first limiting structure 10 to engage with the second limiting structure 201, achieving a limiting engagement and further enhancing the connection stability of the vehicle-mounted female connector 100 and vehicle-mounted male connector 200. The engagement of the first limiting structure 10 and the second limiting structure 201 of the pull rod structure 30 provides an additional mechanical locking mechanism for the connector as a whole, effectively enhancing the connector's resistance to vibration and impact, and reducing the risk of damage to internal components due to vibration.

[0049] When the connector needs maintenance or repair, the operator can rotate the pull rod structure 30 to turn it from the second position back to the first position, thereby releasing the limiting engagement between the first limiting structure 10 and the second limiting structure 201, making it convenient to disassemble and repair the connector, improving maintenance efficiency and reducing maintenance costs.

[0050] According to some embodiments of the present invention, such as Figure 1 As shown, when the pull rod structure 30 is in the first position, the pull rod structure 30 is engaged with the connector body 20 to position the pull rod structure 30 in the first position.

[0051] In the case where the pull rod structure 30 is in the first position, the pull rod structure 30 and the connector body 20 are mutually limiting and engaged to position the pull rod structure 30 in the first position. In some embodiments of this utility model, the pull rod structure 30 and the connector body 20 can be mutually limiting through snap-fit, friction, or magnetic attraction. However, this utility model is not limited to these methods. The pull rod structure 30 and the connector body 20 can also be limited in other ways, as long as the pull rod structure 30 and the connector body 20 are mutually limiting and engaged to position the pull rod structure 30 in the first position.

[0052] By engaging with the connector body 20, the pull rod structure 30 is reliably positioned in the first position when not in use (i.e., when the vehicle female connector 100 is not plugged into the vehicle male connector 200), preventing movement due to vibration, gravity, or accidental contact. This prevents operators from accidentally touching the pull rod structure 30 when the connector is not plugged in, causing it to rotate unexpectedly to the second position, thus avoiding connector damage or safety hazards caused by misoperation.

[0053] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the pull rod structure 30 includes a connecting arm 31 and two rotating arms 32. The two rotating arms 32 are arranged along a first direction and are respectively located on both sides of the connector body 20. The two rotating arms 32 are rotatably disposed on the connector body 20. At least one rotating arm 32 is provided with a first limiting structure 10 on the side away from the connector body 20. The connecting arm 31 is connected between the two rotating arms 32. When the pull rod structure 30 is in the first position, the connecting arm 31 is limited and engaged with the connector body 20.

[0054] The pull rod structure 30 includes a connecting arm 31 and two rotating arms 32. The connecting arm 31 is connected between the two rotating arms 32. The two rotating arms 32 are arranged along a first direction and are respectively located on both sides of the connector body 20. The two rotating arms 32 are rotatably disposed on the connector body 20. In some embodiments of this invention, the rotating arms 32 and the connector body 20 can be rotatably connected by bearings, or the rotating arms 32 and the connector body 20 can be rotatably connected by pins. However, this invention is not limited to these methods. The rotating arms 32 and the connector body 20 can also be rotatably connected by other means, as long as the two rotating arms 32 are rotatably disposed on the connector body 20. By having the two rotating arms 32 located on both sides of the connector body 20, the torsional resistance of the pull rod structure 30 can be improved, avoiding skewing or shaking caused by unilateral force. Furthermore, the presence of the connecting arm 31 can reduce the risk of deformation of the rotating arms 32, thereby effectively improving the stability and reliability of the pull rod structure 30.

[0055] At least one rotating arm 32 has a first limiting structure 10 on one side away from the connector body 20. In some embodiments of this utility model, one rotating arm 32 may have a first limiting structure 10 on one side away from the connector body 20, or both rotating arms 32 may have a first limiting structure 10 on one side away from the connector body 20 (this utility model is described using this embodiment as an example). By having a first limiting structure 10 on one side of both rotating arms 32 away from the connector body 20, and both first limiting structures 10 engaging with the second limiting structure 201 of the vehicle male connector 200, the locking strength between the vehicle female connector 100 and the vehicle male connector 200 can be further enhanced. This can further reduce problems such as poor contact and signal interference caused by insertion deviation, and improve connection quality and performance. During vehicle operation, various complex road conditions and vibration environments are encountered.

[0056] The connecting arm 31 is connected between the two rotating arms 32. When the pull rod structure 30 is in the first position, the connecting arm 31 is in a limiting engagement with the connector body 20. This allows the pull rod structure 30 to be reliably positioned in the first position when it is not in use (i.e., the vehicle female connector 100 is not plugged into the vehicle male connector 200), preventing movement due to vibration, gravity, or accidental contact. It also prevents the operator from accidentally touching the pull rod structure 30 when the connector is not plugged in, causing it to rotate accidentally to the second position, thereby avoiding connector damage or safety hazards caused by misoperation.

[0057] According to some embodiments of the present invention, such as Figure 2 As shown, the connecting arm 31 has a positioning hole 311, and the outer surface of the connector body 20 has a positioning boss 21, which is adapted to be inserted into or removed from the positioning hole 311.

[0058] Specifically, when the positioning boss 21 is inserted into the positioning hole 311, the pull rod structure 30 is fixed in the first position; when the positioning boss 21 is removed from the positioning hole 311, the pull rod structure 30 can be rotated to the second position. Specifically, as shown... Figure 2 and Figure 4 As shown, when the vehicle-mounted female connector 100 is not engaged with the vehicle-mounted male connector 200, the positioning boss 21 inserts into the positioning hole 311, and the pull rod structure 30 is reliably positioned in the first position, preventing movement due to vibration, gravity, or accidental contact. It also prevents operators from accidentally touching the pull rod structure 30 when the connector is not engaged, causing it to rotate accidentally to the second position, thereby avoiding connector damage or safety hazards caused by misoperation.

[0059] When it is necessary to connect the vehicle female connector 100 to the vehicle male connector 200, such as Figure 5 As shown, when the vehicle-mounted male connector 200 is pre-inserted into the vehicle-mounted female connector 100, the vehicle-mounted male connector 200 exerts a compressive force on the pull rod structure 30, causing deformation at the positioning hole 311 of the pull rod structure 30 in a direction away from the positioning boss 21, so that the positioning boss 21 moves out of the positioning hole 311, thereby unlocking the pull rod structure 30 from the first position. By rotating the pull rod structure 30, the pull rod structure 30 can be rotated to the position shown. Figure 6 The second position shown. Alternatively, before the vehicle female connector 100 is inserted and mated with the vehicle male connector 200, the positioning hole 311 of the pull rod structure 30 can be manually bent to deform the positioning hole 311 of the pull rod structure 30 away from the positioning boss 21, thereby moving the positioning boss 21 out of the positioning hole 311, and thus unlocking the pull rod structure 30 from the first position. By rotating the pull rod structure 30, it can be rotated to the position shown. Figure 6 The second position is shown. However, this utility model is not limited to this. As long as the positioning boss 21 can move out of the positioning hole 311 when the vehicle female connector 100 is not plugged into the vehicle male connector 200, the pull rod structure 30 can be rotated to the second position, so that the first limiting structure 10 of the pull rod structure 30 is limited and engaged with the second limiting structure 201 of the vehicle male connector 200.

[0060] According to some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the vehicle-mounted female connector 100 further includes a locking structure 40, which is movably disposed on the outer surface of the connector body 20 along the second direction. The locking structure 40 has an unlocked position and a locked position. When the pull rod structure 30 is in the second position, the locking structure 40 is in the locked position and engages with the pull rod structure 30 to lock the pull rod structure 30 in the second position. The first direction and the second direction intersect.

[0061] Among them, such as Figure 1 The Y-direction shown is the second direction. The first and second directions intersect. As a specific embodiment of this utility model, the first and second directions can be perpendicular to each other. The vehicle-mounted female connector 100 also includes a locking structure 40, which is movably disposed on the outer surface of the connector body 20 along the second direction. Specifically, the connector body 20 may form a slide rail 22 extending along the second direction, and the locking structure 40 may form a slide groove 44 extending along the second direction. The slide rail 22 is fitted into the slide groove 44, and the locking structure 40 is pushed along the second direction to allow the locking structure 40 to move along the second direction.

[0062] Furthermore, the locking structure 40 has an unlocked position and a locked position. When the pull rod structure 30 is in the second position, the locking structure 40 is in the locked position and engages with the pull rod structure 30 to lock the pull rod structure 30 in the second position, preventing the pull rod structure 30 from moving accidentally in the second position. This prevents the limiting engagement between the first limiting structure 10 of the pull rod structure 30 and the second limiting structure 201 of the vehicle male connector 200 from failing. As a secondary locking device, the locking structure 40, in conjunction with the first limiting structure 10 and the second limiting structure 201, forms double protection. This further effectively prevents the vehicle female connector 100 and the vehicle male connector 200 from moving relative to each other along the insertion direction after insertion, ensuring a stable connection between the two and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection, the stability of signal and power transmission, and enhances the overall resistance of the connector to vibration and impact, reducing the risk of damage to internal components of the connector due to vibration, extending the service life of the connector, and ensuring the normal operation of the vehicle's electrical system.

[0063] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the lever structure 30 includes a locking part 33, which has a locking opening 331. The locking structure 40 includes a locking tongue 41. When the lever structure 30 is in the second position, the locking structure 40 moves in the second direction to allow the locking tongue 41 to be inserted into or pulled out of the locking opening 331.

[0064] The locking structure 40 includes a locking tongue 41. When the lever structure 30 is in the second position, the locking structure 40 moves in a second direction to allow the locking tongue 41 to insert into or retract from the locking slot 331. Specifically, as shown... Figure 1 and Figure 6 As shown, the locking part 33 has a locking opening 331, and the locking part 33 also has a locking strip 35. Both ends of the locking strip 35 are connected to the locking part 33, and the locking strip 35 is located inside the locking opening 331. When the latch 41 is inserted into the locking opening 331, at least a portion of the locking structure body 43 presses against the locking strip 35 to fix the pull rod structure 30 in the second position. This prevents the pull rod structure 30 from moving accidentally in the second position, and further prevents the limiting fit between the first limiting structure 10 of the pull rod structure 30 and the second limiting structure 201 of the vehicle male connector 200 from failing. The locking structure 40 serves as a secondary locking mechanism. The locking device, in conjunction with the first limiting structure 10 and the second limiting structure 201, forms a double protection, which can further and effectively prevent the vehicle female connector 100 and the vehicle male connector 200 from moving relative to each other along the insertion direction after insertion, ensuring a stable connection between the two and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection, the stability of signal and power transmission, and also enhances the overall resistance of the connector to vibration and impact, reduces the risk of damage to internal components of the connector due to vibration, extends the service life of the connector, and ensures the normal operation of the vehicle's electrical system.

[0065] When the locking structure 40 moves in the second direction to pull the locking tongue 41 out of the locking port 331, the pull rod structure 30 in the second position is unlocked. At this time, the pull rod structure 30 can resume its rotation function, thereby releasing the limiting relationship between the vehicle male connector 200 and the vehicle female connector 100, which facilitates the later inspection and maintenance of the vehicle male connector 200 and the vehicle female connector 100.

[0066] According to some embodiments of the present invention, such as Figure 1As shown, the connector body 20 has a locking structure 40 with a limiting part 42 on its outer surface. The limiting part 42 forms a limiting hole 421, which extends through the limiting part 42 in a second direction. The locking structure 40 also includes a locking structure body 43, which is fixedly connected to one end of a locking tongue 41. The locking structure body 43 is movably disposed on the connector body 20, and a portion of the locking structure body 43 is installed in the limiting hole 421. When the locking structure 40 is in the unlocked position, the locking tongue 41 is located outside the limiting hole 421, and the free end of the locking tongue 41 is opposite to the limiting part 42 in the second direction. During the rotation of the pull rod structure 30 from the first position to the second position, the pull rod structure 30 is adapted to drive the locking tongue 41 to move toward the connector body 20 so that the free end is opposite to the limiting hole 421. When the pull rod structure 30 is in the second position, the locking part 33 is located on the side of the limiting part 42 away from the locking structure 40.

[0067] The connector body 20 has a locking structure 40 with a limiting part 42 on its outer surface. The limiting part 42 can be constructed in a U-shape, with both ends connected to the connector body 20. The limiting part 42 and the connector body 20 together define a limiting hole 421, which penetrates the limiting part 42 along a second direction. The locking structure 40 also includes a locking structure body 43, which is fixedly connected to one end of a locking tongue 41. In some embodiments of this invention, the locking structure body 43 and the locking tongue 41 can be bonded together, or they can be integrally formed. However, this invention is not limited to these methods, and the locking structure body 43 and the locking tongue 41 can also be connected in other ways, as long as one end of the locking structure body 43 and the locking tongue 41 is fixedly connected.

[0068] The locking structure body 43 is movably disposed on the connector body 20. Specifically, the connector body 20 may form a slide rail 22 extending in the second direction, and the locking structure 40 may form a slide groove 44 extending in the second direction. The slide rail 22 is fitted into the slide groove 44, and the locking structure 40 is pushed in the second direction to allow it to move in that direction. A portion of the locking structure body 43 is mounted in the limiting hole 421. In some embodiments of this invention, one-third or one-quarter of the locking structure body 43 may be mounted in the mounting hole in equal proportions. However, this invention is not limited to this, and the locking structure body 43 may also be mounted in the mounting hole in other proportions, as long as a portion of the locking structure body 43 is mounted in the limiting hole 421. The partial mounting of the locking structure body 43 in the limiting hole 421 can limit the locking structure 40 to the unlocked position.

[0069] When the locking structure 40 is in the unlocked position, the latch 41 is located outside the limiting hole 421, and the free end of the latch 41 is opposite to the limiting part 42 in the second direction, so that the limiting part 42 abuts and limits the free end of the latch 41, thereby restricting the movement of the locking structure 40 in the second direction. The pull rod structure 30 is provided with a pressing boss 34. During the rotation of the pull rod structure 30 from the first position to the second position, the pressing boss 34 of the pull rod structure 30 is adapted to press the latch 41 to drive the latch 41 to move towards the connector body 20 so that the free end of the latch 41 is opposite to the limiting hole 421, thereby allowing the latch 41 to move into the limiting hole 421. By pushing the locking structure 40 into the limiting hole 421, the movement of the locking structure 40 in the second direction can be realized.

[0070] When the pull rod structure 30 is in the second position, the locking part 33 is located on the side of the limiting part 42 away from the locking structure 40. When the locking structure 40 is pushed towards the locking part 33, the locking tongue 41 can be inserted into the locking port 331. When the locking tongue 41 is inserted into the locking port 331, at least a portion of the locking structure body 43 presses against the locking strip 35 to fix the pull rod structure 30 in the second position. This prevents the pull rod structure 30 from moving accidentally in the second position, and further prevents the limiting engagement between the first limiting structure 10 of the pull rod structure 30 and the second limiting structure 201 of the vehicle male connector 200 from failing. The locking structure 40 then... As a secondary locking device, it works in conjunction with the first limiting structure 10 and the second limiting structure 201 to form double protection. It can further and effectively prevent the vehicle female connector 100 and the vehicle male connector 200 from moving relative to each other along the insertion direction after insertion, ensuring a stable connection between the two and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection, the stability of signal and power transmission, and also enhances the overall resistance of the connector to vibration and impact, reduces the risk of damage to internal components of the connector due to vibration, extends the service life of the connector, and ensures the normal operation of the vehicle's electrical system.

[0071] According to some embodiments of the present invention, the vehicle-mounted female connector 100 includes a terminal block 104 and a connecting cable 114, which are welded together.

[0072] The terminal block 104 and the connecting cable 114 can be connected by ultrasonic welding. After the terminal block 104 is stamped and rolled, it is connected to the connecting cable 114 by ultrasonic welding, which can effectively enhance the connection strength between the terminal block 104 and the connecting cable 114, reduce the risk of separation between the terminal block 104 and the connecting cable 114, and thus improve the electrical performance of the vehicle female connector 100. In addition, the angle between the axis of the terminal block 104 and the direction of the connecting cable 114 can be 90°, which can optimize the distribution path of the connecting cable 114, save space, and enable the vehicle female connector 100 to better adapt to narrow spaces or scenarios that require changing the connection direction during installation, improve the flexibility of wiring and space utilization, and facilitate the installation and maintenance of the vehicle female connector 100 on the vehicle.

[0073] Furthermore, such as Figure 3 As shown, the connector body 20 also includes: a housing 101, a first seal 102, a baffle 103, a terminal block 104, an inner shield 105, an outer shield 106, a stop block 107, a lower insulator 108, an upper shield 109, a lower shield 110, a signal terminal 111, a second seal 112, a cover 113, a connecting cable 114, and an upper insulator 115. The surface of the housing 101 is provided with the first seal 102 and the baffle 103. The cable assembly includes: a terminal block 104, an inner shield 105, and an outer shield 106. The connecting cable 114 is fitted with the stop block 107, the second seal 112, and the cover 113. The second seal 112 is located between the stop block 107 and the cover 113. The lower insulating member 108 has a signal terminal 111 on its outer surface. The upper insulating member 115 and the lower insulating member 108 are connected to the cable assembly by snap-fit. The upper insulating member 115 and the lower insulating member 108 are respectively provided with an upper shield 109 and a lower shield 110 on their exteriors. When the outer shield 106 is subjected to force, it is transmitted to the stop 107 and then to the inside of the cover 113. This can prevent the force from acting directly on the terminal 104, prevent the terminal 104 from deforming or dislodging, and also prevent local stress concentration from causing structural damage.

[0074] The stop 107 physically blocks and restricts the axial (PIN removal direction) movement of the terminal 104, preventing the terminal 104 from coming out due to vibration, external force, or inertia during insertion and removal. The stop 107 also serves as a support structure for the second seal 112, ensuring that the second seal 112 is fixed in position within the vehicle female connector 100 and preventing the second seal 112 from shifting due to vibration or pressure changes. This achieves a highly reliable function of blocking the PIN removal of the terminal 104 and sealing the vehicle female connector 100.

[0075] The vehicle according to this utility model embodiment includes the vehicle-mounted female connector 100 of the above embodiment, which can effectively prevent relative movement of the vehicle-mounted female connector 100 and the vehicle-mounted male connector 200 along the insertion direction after insertion, ensuring a stable connection between the two and avoiding loosening of the connection due to external factors such as vibration and impact. This ensures the reliability of the electrical connection, the stability of signal and power transmission, and enhances the overall resistance of the connector to vibration and impact, reducing the risk of damage to internal components of the connector due to vibration, extending the service life of the connector, and ensuring the normal operation of the vehicle's electrical system. In addition, the terminal block 104 and the connecting cable 114 are ultrasonically welded, which can improve the connection reliability of the terminal block 104 and the connecting cable 114, thereby improving the reliability of the electrical connection of the connector.

[0076] The housing 101 of the vehicle-mounted female connector 100 is made of nylon material. Nylon material has high strength, toughness, wear resistance and self-lubrication. Combined with good processability, chemical resistance and lightweight characteristics, it can not only effectively improve the safety and reliability of the vehicle, but also help the vehicle's lightweight design.
