At the same time, terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0025] In order to describe the present invention in detail, first, the connector and the car seat assembly of the present invention are specifically described below.

[0026] like Figures 1 to 6 As shown, the present application provides a connector, comprising a plug 1 and a socket 2, wherein the socket 2 is detachably connected to the plug 1. The plug 1 is provided with a pin, and the socket 2 is provided with a socket matching the pin. The middle portion of the plug 1 of this embodiment is hollow, forming a cavity. When the socket 2 is mated with the plug 1, the socket 2 is located in the cavity, and the lower half of the outer wall of the socket 2 is located in the cavity of the plug 1.

[0027] A first locking structure is provided between the socket 2 and the plug 1. This structure is used to lock the plug 1 and socket 2 together. Located between the inner wall of the plug 1 and the outer wall of the socket 2, the structure prevents contact with other components when locked. The front of the socket 2 has an opening through which the wiring harness enters the socket 2 and connects with the corresponding jack therein. After the plug 1 and socket 2 are mated and connected, the opening is located above the plug 1 and is not obscured by the plug 1. The wiring harness connects to the bottom of the plug 1.

[0028] The first locking structure includes a locking body 5 and a blocking member 6. The locking body 5 is rotatably set on one of the plug 1 or the socket 2, and the blocking member 6 is set on the other part. For example, if the locking body 5 is rotatably set on the inner wall of the plug 1, the blocking member 6 is fixedly set on the outer wall of the socket 2. Preferably, for ease of installation, the locking body 5 can be rotatably set on the outer wall of the socket 2, and the blocking member 6 is set on the inner wall of the plug 1.

[0029] The locking body 5 is rotatably connected to the socket 2. A first protrusion 7 is provided on the edge of the locking body 5, and a stopper 6 is used to limit the position of the first protrusion 7. The locking body 5 is rotatably connected to the outer wall of the socket 2, and the locking body 5 can rotate about the connection point. When the first protrusion 7 is below the stopper 6, the locking body 5 cannot rotate further, and the socket 2 and plug 1 are locked and cannot be separated. Only by rotating the locking body 5 in the opposite direction, when the first protrusion 7 is no longer blocked by the stopper 6, can the plug 1 and socket 2 be separated.

[0030] A rotating shaft is provided on the outer wall of the socket 2, with two stopper protrusions disposed on the rotating shaft. A connecting hole is provided in the middle of the locking body 5, with a boss disposed within the connecting hole. When the connecting hole is aligned with the stopper protrusions, the locking body 5 is connected to the rotating shaft. When the locking body 5 is rotated, the stopper protrusions are located on the bosses, and the locking body 5 is rotated without falling out of the connecting hole. A cover plate may also be provided at the connecting hole, connected to the rotating shaft, thereby retaining the locking body 5 within the rotating shaft and preventing it from sliding out.

[0031] The edge of the locking body 5 is further provided with a second protrusion 8, which is spaced apart from the first protrusion 7. When the socket 2 is inserted into the plug 1, the blocking member 6 is located between the first protrusion 7 and the second protrusion 8, and the blocking member 6 will not be blocked by the second protrusion 8 to prevent it from being inserted.

[0032] To prevent the locking body 5 from rotating freely, this embodiment includes a shift member 9 on the edge of the locking body 5. This shift member 9 is a protrusion that extends toward the outer wall of the socket 2. A gap 10 is defined between the bottom of the shift member 9 and the outer wall of the socket 2, meaning that the bottom of the shift member 9 does not contact the outer wall of the socket 2. A shift block 3 is also mounted on the outer wall of the socket 2. One end of the shift block 3 is connected to the outer wall of the socket 2, while the other end is a movable end that abuts the shift member 9. This movable end of the shift block 3 is capable of being pressed down, allowing for a certain amount of movement. When the movable ends are located on either side of the shift member 9, the locking body 5 is in different positions: locked and released. Alternatively, a blocking protrusion 24 similar to the shift member 9 can be provided on the edge of the locking body 5. When the movable end passes through the shift member 9 and is in the locked position, the blocking protrusion 24 cooperates with the movable end to prevent further rotation of the locking body 5.

[0033] When the movable end of the shift block 3 is pressed toward the outer wall of the socket 2 , the locking body 5 is rotated, and the movable end can pass through the gap 10 and separate from the shift member 9 , and then the movable end of the shift block 3 abuts against the blocking protrusion 24 .

[0034] To ensure smooth entry of the shift block 3 into the gap 10 between the shift member 9 and the outer wall of the socket 2, the shift member 9 is angled at both ends. This provides a guide for the locking body 5 during rotation, allowing for relatively easy rotation. The shift member 9 is shaped like a trapezoid, and the trapezoidal waist allows the movable end to smoothly enter the gap 10 between the shift member 9 and the outer wall of the socket 2 from both sides of the trapezoid.

[0035] Among them, in order to ensure that the movable end of the gear block 3 can be pressed down smoothly when the plug 1 contacts the socket 2, a starting protrusion 4 is provided on the gear block 3, and the starting protrusion 4 protrudes toward the side away from the outer wall of the socket 2. A pressing protrusion 11 is provided on the inner wall of the plug 1, and the pressing protrusion 11 cooperates with the starting protrusion 4 to press the movable end of the gear block 3 toward the outer wall of the socket 2.

[0036] The pressing protrusion 11 is provided with guide sections 12 on both sides along the insertion direction of the socket 2. The guide sections 12 obliquely connect the inner wall of the plug 1 with the pressing protrusion 11, so that the starting protrusion 4 is slowly pressed downward after contacting with the guide section 12, which has a certain transition effect. When the starting protrusion 4 contacts with the pressing protrusion 11, the gear block 3 can be pressed down smoothly, and the locking body 5 is rotated so that the movable end of the gear block 3 can pass through the gap 10 more smoothly.

[0037] Specifically, to facilitate locking, locking bodies 5 are provided on both sides of the outer wall of the socket 2, while blocking members 6 are provided on both sides of the inner wall of the plug 1. To allow the locking bodies 5 on both sides to be locked and released simultaneously for easy control, a rocker arm 13 is provided to connect the locking bodies 5 on both sides. The rocker arm 13 is U-shaped, with the top end of the rocker arm 13 located on the side away from the plug 1 after the plug 1 and socket 2 are mated. The rocker arm 13 is integrally formed with the locking body 5.

[0038] In order to prevent the plug 1 and the socket 2 from being blocked by the rocker arm 13 when they start to mate, the present application provides a limit block 14 on the outer wall of the socket 2. The limit block 14 blocks the rocker arm 13. When the rocker arm 13 is blocked by the limit block 14, it cannot continue to rotate downward. At this time, the gear block 3 abuts against the shift member 9.

[0039] In order to prevent the rocker arm 13 in the locked state from being rotated during use, causing the plug 1 and the socket 2 to separate, the present application provides a second locking structure on the side of the socket 2 away from the plug 1. The rocker arm 13 is locked by the second locking structure, and the double locking method makes the connection between the plug 1 and the socket 2 more secure.

[0040] The second locking structure includes a locking hole 15 provided at the top of the socket 2 and a locking block 16 that cooperates with the locking hole 15. One end of the locking block 16 can be inserted into the locking hole 15, and the other end of the locking block 16 is provided with a pressing portion 25. The pressing portion 25 facilitates manual movement of the locking block 16 and can also be used to position the locking block 16. In this embodiment, the pressing portion 25 is provided along the width of the locking hole 15, forming a T-shape between the pressing portion 25 and the locking block 16. The two side edges of the pressing portion 25 do not contact the socket 2, which makes it easy to pull out the locking block 16.

[0041] The locking block 16 is provided with a slot 17, and the socket 2 is provided with a locking block 18. The locking block 18 is inserted into the slot 17 to lock the locking block 18. The slot 17 is trapezoidal, and the opening size of the slot 17 gradually decreases from the side away from the pressing portion 25 to the side closer to the pressing portion 25. After locking, the rocker arm 13 is located on the side of the locking block 18 away from the pressing portion 25. The rocker arm 13 is blocked by the locking block 18 and cannot rotate toward the pressing portion 25. At this time, the locking block 18 is located in the slot 17 and cannot be pressed downward. The rocker arm 13 is locked. When the locking block 16 moves toward the outside of the locking hole 15, the locking block 18 disengages the slot 17 and can be pressed downward. In this way, the rocker arm 13 can rotate toward the pressing portion 25, thereby separating the rocker arm plug 1 and the socket 2.

[0042] A sliding groove 19 is provided on the inner wall of the locking hole 15 , and a slider 20 is provided on the side of the locking block 16 , so that after the locking block 16 enters the locking hole 15 , the locking block 16 is limited by the sliding groove 19 and cannot move up and down.

[0043] To ensure precise alignment of the plug 1 and socket 2 during initial mating, several guide protrusions 21 are provided on either side of the outer wall of the socket 2. Guide grooves 22 are located on the inner wall of the plug 1, corresponding to the guide protrusions 21. Positioning posts 23 are located within the plug 1, and positioning holes mate with these posts 23 within the socket 2. This provides guidance during mating between the plug 1 and socket 2 and prevents misalignment that could damage the pins. Multiple positioning posts 23 can be configured in different sizes or shapes. This prevents insertion if the plug is inserted the wrong way, preventing contact between the pins and the socket, further enhancing the socket's effectiveness.

[0044] Working process: The rocker arm 13 is in the release position, the rocker arm 13 contacts the limit block 14, the socket 2 is inserted into the plug 1, the guide protrusion 21 is located in the guide groove 22, the blocking member 6 contacts the second protrusion 8, and the blocking member 6 is located between the second protrusion 8 and the first protrusion 7. Figure 5 As shown, the socket 2 continues to move downward, and the starting protrusion 4 is gradually pressed downward by the guide section 12 until the starting protrusion 4 cooperates with the pressing protrusion 11, and the gear block 3 is pressed down to the lowest position. After the plug 1 and the socket 2 are installed, the rocker arm 13 is rotated, and the movable end of the rotating gear block 3 passes through the gap 10, the gear block 3 is separated from the shift member 9, and the first protrusion 7 contacts the blocking member 6, so that the rocker arm 13 is in the locked position, and the locking block 16 is slid into the locking hole 15. The locking block 18 is embedded in the card slot 17. The locking block 18 cannot be pressed downward, and the rocker arm 13 is fixed in the position by the locking block 18 and cannot be rotated. The rocker arm 13 is locked, as shown in FIG. Figure 6 shown.

[0045] When the plug 1 and the socket 2 are separated, the locking block 16 is partially pulled out so that the locking block 18 is disengaged from the slot 17. In this way, the locking block 18 can be pressed downward to allow the rocker arm 13 to rotate. After the first protrusion 7 is no longer blocked by the blocking member 6, the plug 1 and the socket 2 can be separated.

[0046] On the other hand, the present application also provides a car seat assembly, including the above-mentioned connector. A mounting structure is provided on the outer wall of the plug 1, which can be fixed to the bottom of the car seat. The present application integrates the conventional seat wiring harness and the seat airbag wiring harness into a single connector. In the case of limited space at the bottom of the car seat, it can facilitate the layout of the wiring harness. In situations where two or more plug-in connections are required, the connector provided by the present application only requires one plug-in. The terminal layout within the plug 1 and the socket 2 can be designed according to the specific situation, so that the layout is reasonable and the connection is convenient.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
