DETAILED DESCRIPTION

[0025] like Figures 1 to 6 As shown, the present invention discloses a connector that can be plugged in and out in both directions, including a plug assembly 1 and a socket assembly 2 that cooperates with the plug. The plug assembly 1 includes a plug body 3, a plug barrel 4, two power pins 5 and at least two signal pin holders 6. The plug body 3 can accommodate cables, and the plug barrel 4 is fixed on one side of the plug body 3. The two cooperate to form a brush shape. There are two power pins 5, which are connected to the positive pole and the negative pole respectively. There are 8 signal pin holders 6, which are arranged in two rows according to the sequence, and each row has 4 pins. The signal pin holders 6 are evenly spaced and arranged in the installation area formed on the inner side of the plug barrel 4, and the two power pins 5 are installed on both sides of the signal pin holder 6; the signal pin holder 6 in the embodiment of the present invention is located on the upper inner side of the installation area of ​​the plug barrel 4, which can easily distinguish the forward and reverse directions.

[0026] Correspondingly, the socket assembly 2 of the present invention includes a socket body 7, a socket barrel 8, a rotating disk 9, two power pin seats 10 and at least two signal pins 11. The socket barrel 8 is fixed to one side of the socket body 7. The inner wall shape of the socket barrel 8 corresponds to the outer shape of the plug barrel 4, so that the plug barrel 4 can be smoothly inserted into the socket barrel 8 along the axial direction. In this embodiment, the shapes of the plug barrel 4 and the socket barrel 8 are symmetrical, so that the plug barrel 4 can be stably matched with the socket barrel 8 at least after rotating 180°.

[0027] Specifically, a circular turntable 9 is rotatably provided in the installation area formed inside the socket barrel 8. The specific area of ​​the turntable 9 is smaller than the area of ​​the entire installation area. The signal pins 11 are evenly spaced and arranged on the turntable 9. There are 8 corresponding signal pins 11. When the signal pins 11 rotate 180°, they just correspond to the reverse signal pin holder 6. Two power pin holders 10 are installed on both sides of the signal pin 11. The socket barrel 8 is plugged and matched with the plug barrel 4. The power pin holder 10 corresponds to the power pin 5 one by one, and the signal pin 11 corresponds to the signal pin holder 6 one by one. A rotation drive assembly is installed between the plug body 3 and the socket body 7. Before the socket barrel 8 is plugged and matched with the plug barrel 4, the rotation drive assembly can drive the turntable 9 to rotate 180°.

[0028] During use of the connector of the present invention, when the plug assembly 1 and the socket assembly 2 are reversely plugged in and out, since the plug assembly 1 itself is rotated 180°, before the two are mated, the rotation drive assembly is activated, and the rotation drive assembly can drive the turntable 9 to rotate 180°, so that the signal pin 11 and the power pin seat 10 installed on the socket body 7 can also be adaptively rotated 180°. At this time, the signal pin 11 and the power pin seat 10 can normally cooperate with the plug assembly 1 after the U-turn, thereby solving the problem that it is difficult for users to accurately judge the insertion direction of the connector, resulting in connection failure or prolonged operation time.

[0029] In this embodiment, the rotation drive assembly includes a ring gear 12, a driving gear 13, a threaded rod 14, and a guide rod 15. The ring gear 12 is installed on the outer side of the turntable 9. The ring gear 12 and the turntable 9 are formed integrally. A space is provided on the socket body 7 for the ring gear 12 to make way when rotating. The ring gear 12 is meshed with the driving gear 13 on the outer side. The driving gear 13 is rotatably installed in the socket body 7. The driving gear 13 is coaxially connected to the threaded rod 14. The threaded rod 14 and the guide rod 15 are arranged at intervals on the upper and lower sides of the socket body 7 and both extend from the end surface of the socket tube 8. A through hole 16 and a threaded hole 17 are respectively provided on the end surface of the plug tube 4, and the through hole 16 and the threaded hole 17 correspond to the threaded rod 14 and the guide rod 15 respectively.

[0030] When plugging and unplugging in the forward direction: move the plug assembly 1 toward the side of the socket assembly 2. When the plug body 3 and the socket body 7 are close to each other, the guide rod 15 is inserted into the threaded hole 17, and the diameter of the guide rod 15 is smaller than the inner diameter of the threaded hole 17. The threaded rod 14 is inserted into the through hole 16, and the outer diameter of the threaded rod 14 is smaller than the diameter of the through hole 16. Under the cooperation of the plug tube 4 and the socket tube 8, the guide rod 15 is normally inserted into the threaded hole 17, the threaded rod 14 is normally inserted into the through hole 16, the turntable 9 does not rotate, the signal pin 11 cooperates with the signal pin seat 6, and the power pin 5 and the power pin seat 10 cooperate normally.

[0031] When plugging and unplugging in reverse: the head of the plug body 3 faces downward, the head of the socket body 7 faces upward and is fixed, the plug assembly 1 is moved toward the side of the socket assembly 2, and when the plug body 3 and the socket body 7 are close to each other, the guide rod 15 is inserted into the through hole 16, the diameter of the guide rod 15 is smaller than the inner diameter of the through hole 16, the threaded rod 14 is inserted into the threaded hole 17, the plug barrel 4 and the socket barrel 8 cooperate, the threaded hole 17 drives the threaded rod 14 to rotate, the threaded rod 14 drives the driving gear 13 to rotate together, the driving gear 13 drives the turntable 9 engaged therewith, and after the turntable 9 rotates 180°, the signal pin 11 and the power pin seat 10 installed on the socket body 7 can also be adaptively turned 180°, and then the signal pin 11 and the signal pin seat 6 cooperate normally, and the power pin 5 and the power pin seat 10 cooperate normally.

The elastic support device 19 of the present invention adopts a spring to provide an outward elastic support force to the slide 18. When the connector is plugged in and out in the forward direction, the threaded rod 14 can push the slide 18 to move inward so as to avoid the threaded rod 14 and avoid interference. When plugging in and out in the reverse direction, after the guide rod 15 is inserted into the through hole 16, the guide rod 15 can be inserted into the inner side of the slide 18 at the same time, which plays a guiding role in the plugging of the device, reduces the occurrence of problems such as jamming, makes the connection between signals and power supplies closer, and increases the stability of the connector when connected.

The socket tube 8 is tightly matched with the outer wall of the plug tube 4 through the elastic rubber ring 26, so that the connection between the plug tube 4 and the socket tube 8 can be more stable.

[0037] In this embodiment, the socket body 7 includes a base 27, a first limit plate 28 and a second limit plate 29 detachably connected to the base 27, an inner concave surface 30 for rotationally cooperating with the turntable 9 is provided on the base 27, a first concave surface and a second concave surface for rotationally cooperating with the turntable 9 are provided on the first limit plate 28 and the second limit plate 29, respectively, an annular groove 31 for the gear ring 12 to give way is provided on the first concave surface and the second concave surface, and the first limit plate 28 and the second limit plate 29 are detachably connected to each other.
