[0041] Please continue to refer to Figure 6In some optional embodiments, the first shell 11 further comprises a hanging structure 114 which is arranged in the space between the insertion part 112 and the first shell 11 to form a plug-in space 115. The side wall forming the opening part 211 is provided with a mounting groove 212, the side wall is inserted into the plug-in space 115, and the hanging structure 114 is inserted into the mounting groove 212 to realize the connection between the first connection main body 1 and the second connection main body 2. For example, the hanging structure 114 is a protruding structure extending axially along the first shell 11 and is arranged on the outer side of the insertion part 112 to form the plug-in space 115. When the first connection main body 1 and the second connection main body 2 are connected, the side wall forming the opening part 211 in the second shell 21 is arranged in the plug-in space 115, and the hanging structure 114 is also arranged in the mounting groove 212, thereby increasing the contact area between the first connection main body 1 and the second connection main body 2, improving the stability of the connection between the first connection main body 1 and the second connection main body 2, and facilitating the connection and disconnection, thereby improving the disassembly efficiency. The double fixing mode of the hanging structure 114 and the threaded connection can improve the anti-vibration performance between the first connection main body 1, the second connection main body 2 and the control circuit board.

[0042] Please continue to refer to Figure 6 and Figure 8 In some optional embodiments, the hanging structure 114 comprises a first step structure 1141, the mounting groove 212 is provided with a second step structure 213, the hanging structure 114 is inserted into the mounting groove 212, and the first step structure 1141 abuts against the second step structure 213.

[0043] The traditional connector is injection molded, which is a mature process, easy to operate, and has high production efficiency. Based on the characteristics of the raw materials for injection molding, the hanging structure 114 can be prepared as an elastic structure. During assembly, the operator squeezes the hanging structure 114 to help it enter the mounting groove 212, and after releasing the hanging structure 114, the first step and the second step abut against each other.

[0044] Please refer to Figure 9 In some optional embodiments, a sealing glue filling groove 14 is arranged between the fixing plate 13 and the mounting part 111 to fill glue for fixing the pin 12. For example, the glue filling groove 14 is arranged at the position where the first mounting cavity 1111 and the second mounting cavity 131 are connected, and after the pin 12 is installed, glue is filled from the glue filling groove 14, and after curing, the pin 12 is further fixed.

[0045] Please refer toFigure 10 In some optional embodiments, the first mounting cavity 1111 comprises a first straight-through section 1112, an arc-shaped section 1113 and a second straight-through section 1114 arranged along the axial direction, and the arc-shaped section 1113 is arranged between the first straight-through section 1112 and the second straight-through section 1114 to prevent the insertion pin 12 from moving along the axial direction of the first shell 11. The structural design of the first mounting cavity 1111 forms a retreat-preventing structure, which avoids the insertion pin 12 from being driven by the external circuit to move along the axial direction of the first mounting cavity 1111 during plugging and unplugging, thereby improving the reliability of the connector and facilitating the application of the connector in harsh application scenarios such as monitor devices and electronic controls in the electronic and computer fields.

[0046] Please refer to Figure 3 and Figure 11 In some optional embodiments, the first shell 11 further comprises an interface portion 116 arranged on the side of the mounting portion 111 away from the second connection main body 2 and internally hollow and in communication with the first mounting cavity 1111. One end of the insertion pin 12 extends into the interface portion 116 after passing through the first mounting cavity 1111, and the outer side of the interface portion 116 is provided with a fool-proof structure 1161. Exemplarily, the fool-proof structure 1161 is a groove or a protrusion arranged on the outer side of the interface portion 116. Correspondingly, the external circuit is provided with a protrusion corresponding to the groove or a groove corresponding to the protrusion, so as to avoid the reverse plugging of the external circuit and the connector during plugging, thereby improving the accuracy and efficiency of circuit connection.

[0047] In some optional embodiments, the interior of the interface portion 116 is provided with a wrong-plugging prevention key 1162. In order to prevent line connection errors, the wrong-plugging prevention key 1162 can be arranged in the connector based on the fact that multiple connectors and external circuits can be arranged in one device, so as to avoid the occurrence of unsafe accidents caused by line connection errors. Exemplarily, the wrong-plugging prevention key 1162 is a protruding rod member extending along the axial direction of the first shell 11, which can be a cylinder or a multi-ribbed body. In order to avoid line connection errors, the protruding rod member can be a multi-ribbed body with different angles to distinguish multiple connectors. Of course, the wrong-plugging prevention key 1162 can also be a recessed structure matched with the structure on the element opposite thereto.

[0048] In some optional embodiments, the second shell 21 is provided with multiple through holes 214 corresponding to the positions of the indicator lights on the control circuit board, so as to emit the light of the indicator lights to the outside of the connector, thereby making it easy to see the lighting of the indicator lights representing the working state of the control circuit board, so as to facilitate the understanding of the working state of the control circuit board and the connector.

[0049] In some optional embodiments, the first shell 11 is provided with an anti-collision bone site 117, so that the connector can play a good protection role against being damaged when it is accidentally dropped on the hard ground, and the product quality is more guaranteed. For example, the anti-collision bone site 117 is an anti-collision rib (or anti-collision protrusion) provided on the first shell 11 and arranged on the side of the first shell 11 away from the second connecting body 2. The anti-collision bone site 117 can be synchronously formed when the first shell 11 is injection molded, and is made of the same material as the first shell 11. Alternatively, the anti-collision bone site 117 can be fixed to the first shell 11 by pasting or the like after the first shell 11 is formed. At this time, the anti-collision bone site 117 can be made of a rubber material or the like with elasticity, and can play a good buffering protection role when the first shell 11 is dropped on the ground.
