A plurality of jack sockets 101 are provided, and the plurality of jack sockets 101 enclose a circle, and an interval gap is provided between each jack socket 101. The end of the jack socket 101 for connecting to the plug is divided into a first arc-shaped flap 1011 and a second arc-shaped flap 1012. The first arc-shaped flap 1011 and the second arc-shaped flap 1012 in the same jack socket 101 enclose to form a jack; the end of the jack socket 101 away from the plug is connected to the cable 107. The first arc-shaped flap 1011 is located on the side where the jack sockets 101 are close to each other, and the second arc-shaped flap 1012 is located on the side where the jack sockets 101 are away from each other, that is, the first arc-shaped flaps 1011 of the plurality of jack sockets 101 enclose an inner circle, and the second arc-shaped flaps 1012 of the plurality of jack sockets 101 enclose an outer circle.

[0028] A abutting member 102 is inserted between the first arc-shaped inserting flaps 1011. The abutting member 102 is a columnar structure in the shape of a flower. That is, the abutting member 102 includes a limiting portion 1021 for the first arc-shaped inserting flaps 1011 to abut against and a separating portion 1022 for separating each socket base 101. The separating portions 1022 are evenly distributed along the circumference of the limiting portion 1021. The separating portions 1022 are respectively located in the gap spaces between the socket bases 101 to limit the socket bases 101.

[0029] An elastic limiting member 103 is arranged outside the second arc-shaped inserting flap 1012. The arrangement of the elastic limiting member 103 makes the second arc-shaped inserting flap 1012 always keep a tendency to approach the first arc-shaped inserting flap 1011. The elastic limiting member 103 includes a connecting portion 1031 and a claw-shaped pre-tightening portion 1032. The connecting portion 1031 is in a circular ring shape and is used to be fixed to the socket body 1. The claw-shaped pre-tightening portion 1032 is arranged on the connecting portion 1031. The claw-shaped pre-tightening portion 1032 extends along the outer surface of the second arc-shaped inserting flap 1012, so that the outer surface of the second arc-shaped inserting flap 1012 is in close fit with the inner surface of the claw-shaped pre-tightening portion 1032. In this embodiment, along the direction in which the socket base 101 is far away from the socket body 1, the thickness of the claw-shaped pre-tightening portion 1032 gradually decreases, so that the surface of the claw-shaped pre-tightening portion 1032 is in an arc shape.

[0030] A connecting sleeve 104 for fixing with the plug is sleeved on the socket body 1. The connecting sleeve 104 is slidably mounted on the socket body 1 along its own axis. The socket body 1 is protrudingly provided with a first limiting boss 105 and a second limiting boss 106. The first limiting boss 105 is arranged at one end of the connecting sleeve 104 far away from the socket base 101, and the second limiting boss 106 is arranged at one end of the socket body 1 close to the socket base 101, and the second limiting boss 106 is arranged inside the connecting sleeve 104. One end of the connecting sleeve 104 close to the first limiting boss 105 is bent towards the socket body 1 to be provided with a bending portion 1041, and the connecting sleeve 104 is limited by abutting the bending portion 1041 against the first limiting boss 105 or the second limiting boss 106. The connecting sleeve 104 is provided with an internal thread for connecting with the plug to realize the fixation between the plug and the socket.

[0031] As Figures 6 to 8 shown, this embodiment also discloses a plug, which includes a plug body 2. Insertion pins 202 are arranged on one end face of the plug body 2. The number of the insertion pins 202 is matched with the number of the jacks on the socket. A pre-tightening cavity 201 is arranged outside the insertion pins 202. The pre-tightening cavity 201 is fixed to the end face of the plug body 2. The inner cavity of the pre-tightening cavity 201 is matched with the outer wall of the claw-shaped pre-tightening portion 1032 on the plug. The pre-tightening cavity 201 is provided with an external thread for matching with the connecting sleeve 104.

[0032] In addition, this embodiment also discloses a connector, including the above-mentioned plug and the above-mentioned socket. The pin 202 on the plug is used to be inserted into the jack between the first arc-shaped flap 1011 and the second arc-shaped flap 1012. The inner wall of the pre-tightening cavity 201 on the plug is used to match the outer wall of the pre-tightening limiting component on the socket. The external thread on the outer wall of the pre-tightening cavity 201 is used to match the internal thread on the connecting sleeve 104.

[0033] During use, as the pin 202 is gradually inserted into the jack, the pre-tightening cavity 201 presses on the claw-shaped pre-tightening part 1032, thereby causing the second arc-shaped flap 1012 and the first arc-shaped flap 1011 to tightly press the pin 202, avoiding the situation of poor contact. After the pin 202 is completely inserted into the jack, slide the connecting sleeve 104 in the direction of the plug, and at the same time rotate the connecting sleeve 104 so that the connecting sleeve 104 is threadedly connected to the outer wall of the pre-tightening cavity 201, preventing the plug and the socket from detaching.
