[0037] The embodiment proposes a vehicle, which can be a car, a truck, a motorcycle or other types of vehicles, which are not specifically limited herein. The circuit is connected through the connector assembly to realize the circuit conduction, so that the circuit realizes the predetermined function.

[0038] The existing connector assembly usually comprises a socket connector and a plug connector, the pins of the socket connector are inserted into the plug of the plug connector to achieve effective connection of the connectors. In order to prevent the two connector from being loose or falling off, a locking mechanism is usually arranged between the two connectors to cooperate with each other, and the locking device is mostly in the form of threaded connection or buckle structure, the threaded connection is achieved by relative rotation of the two connectors; the buckle structure is achieved by rotating the buckle arm of one connector into the card slot of the other connector to achieve clamping and fixing. The existing locking mechanism causes the insertion and separation process of the socket connector and the plug connector to be complicated and time-consuming, which reduces the disassembly efficiency of the connector assembly.

[0039] To solve the above problems, as shown in Figures 1-3 The embodiment also provides a connector assembly, which comprises a socket connector 1 and a plug connector 2, the socket connector 1 comprises an inner shell 11 and pins 12 arranged inside the inner shell 11. The plug connector 2 comprises an outer shell 21, a plug 22, a variable-diameter locking ring 23 and an unlocking piece 24, the plug 22 is arranged in the outer shell 21, the variable-diameter locking ring 23 is coaxially sleeved in the outer shell 21, and the unlocking piece 24 is arranged in the outer shell 21 along the axial direction of the outer shell 21 and has an unlocking position for pressing the inner side of the variable-diameter locking ring 23. The inner shell 11 can be arranged in the variable-diameter locking ring 23 and the outer shell 21, the pins 12 are inserted into the plug 22, and the variable-diameter locking ring 23 is configured to tightly hold the inner shell 11 when the unlocking piece 24 is away from the unlocking position, and to expand and release the inner shell 11 when the unlocking piece 24 moves to the unlocking position.

[0040] When the socket connector 1 and the plug connector 2 are assembled, the unlocking piece 24 is away from the unlocking position, the inner shell 11 is arranged in the variable-diameter locking ring 23 and the outer shell 21, and the pins 12 are inserted into the plug 22, and the variable-diameter locking ring 23 tightly holds the inner shell 11; when the socket connector 1 and the plug connector 2 are separated, the unlocking piece 24 moves to the unlocking position along the axial direction of the outer shell 21 to press the inner side of the variable-diameter locking ring 23, so that the locking ring expands and releases the inner shell 11, thereby realizing the quick separation of the socket connector 1 and the plug connector 2. By tightly holding the inner shell 11 through the variable-diameter locking ring 23, the stable connection of the socket connector 1 and the plug connector 2 is realized, by pulling the unlocking piece 24 to the unlocking position along the axial direction of the outer shell 21 to press the inner side of the variable-diameter locking ring 23, the variable-diameter locking ring 23 expands and is out of contact with the inner shell 11, so as to release the inner shell 11, thereby realizing the quick separation of the socket connector 1 and the plug connector 2, simplifying the disassembly operation of the connector assembly and improving the disassembly efficiency of the connector assembly.

[0041] Specifically, as shown in Figure 2 and Figure 3As shown, the socket connector 1 further comprises support plates 13 and a first waterproof ring 14. The support plates 13 are provided in two, and are arranged in an axial direction (left-right direction in the figure) of the inner shell 11. The outer side of the inner shell 11 in the circumferential direction is provided with a stepped surface. Part of the inner shell 11 is clamped between the two support plates 13. The inner side of the left end of the inner shell 11 is provided with waterproof glue. The pins of the pins 12 are injection molded in the waterproof glue and pass through the left support plate 13 to electrically connect with the external wiring harness. The right end of the inner shell 11 protrudes from the right support plate 13 to be inserted into the inner side of the outer shell 21. The first waterproof ring 14 is sleeved on the inner shell 11 and clamped between the stepped surface of the inner shell 11 and the right support plate 13 to ensure the waterproof performance of the socket connector 1. It should be noted that the outer shell 21 and the inner shell 11 are both made of high-temperature-resistant plastic. The inner shell 11 is screwed between the two support plates 13 to realize stable assembly of the socket connector 1. A waterproof gasket is installed between the inner shell 11 and the screw to ensure the waterproof effect of the inner shell 11.

[0042] As shown in Figure 3 and Figure 4 The plug connector 2 further comprises a second waterproof ring 25, a third waterproof ring 26 and a cable 27. The outer shell 21 comprises a main shell 211 and a copper ring 212. One end of the main shell 211 is wrapped by the skin of the end of the cable 27 to realize insulation and waterproof. The inner side of the other end of the main shell 211 is provided with the copper ring 212. The main shell 211 and the skin of the cable 27, and the main shell 211 and the copper ring 212 are fixedly connected by a buckle structure. The plug 22 is fixedly installed in the main shell 211 and electrically connected with the wiring harness in the cable 27 through waterproof glue. The second waterproof ring 25 is sleeved on the outer ring of the plug 22 and tightly abuts against the inner side of the main shell 211. The third waterproof ring 26 is also sleeved on the plug 22. When the pins 12 are inserted into the plug 22, the right end of the inner shell 11 abuts against the second waterproof ring 25, and the third waterproof ring 26 is clamped between the inner shell 11 and the plug 22 to realize the double-layer waterproof effect of the connector assembly.

[0043] As shown in Figure 3 and Figure 5As shown, the outer side of the inner shell 11 is provided with a locking groove 111 in the circumferential direction, and the variable-diameter locking ring 23 is clamped in the locking groove 111 to tightly hold the inner shell 11. When the socket connector 1 and the plug connector 2 are close to each other in the left-right direction in the drawing, the inner shell 11 extends into the outer shell 21 and passes through the variable-diameter locking ring 23, and the inner side of the variable-diameter locking ring 23 is pressed and expanded. When the inner shell 11 continues to extend into the outer shell 21, the variable-diameter locking ring 23 slides into the locking groove 111, the variable-diameter locking ring 23 shrinks and tightly holds the inner bottom wall of the locking groove 111, and at this time the socket connector 1 and the plug connector 2 are assembled in place. By clamping the variable-diameter locking ring 23 and the locking groove 111, the relative position of the inner shell 11 and the outer shell 21 is locked, avoiding the socket connector 1 and the plug connector 2 from being loosened, and further improving the stable connection of the connector assembly.

[0044] As shown in Figure 4 and Figure 5 The variable-diameter locking ring 23 includes a mounting ring 231 and a locking tooth 232, and the mounting ring 231 is coaxially sleeved in the outer shell 21. The mounting ring 231 is provided with a plurality of elastic locking teeth 232 in the circumferential direction, and the ends of the plurality of locking teeth 232 away from the mounting ring 231 are surrounded to form a ring. When the unlocking member 24 moves away from the unlocking position, the inner side of the locking tooth 232 is pressed to expand the ring; when the unlocking member 24 moves away from the unlocking position, the locking tooth 232 is separated to shrink the ring. Specifically, the mounting ring 231 is clamped and mounted between the main shell 211 and the copper ring 212 to realize stable installation of the variable-diameter locking ring 23. At the same time, the plurality of elastic locking teeth 232 form a tapered ring structure around the mounting ring 231, so that when the unlocking member 24 presses the inner side of the locking tooth 232, the plurality of locking teeth 232 move away from each other, so that the ring expands (the diameter increases); when the unlocking member 24 is separated from the locking tooth 232, the plurality of locking teeth 232 move close to each other under the action of the elastic restoring force, so that the ring shrinks (the diameter decreases), so as to adjust the diameter of the variable-diameter locking ring 23.

[0045] As shown in Figures 3-5 The unlocking member 24 includes a sliding sleeve 241, which is coaxially sleeved in the outer shell 21, and the inner shell 11 extends into the outer shell 21 and is sequentially arranged in the sliding sleeve 241 and the variable-diameter locking ring 23. The sliding sleeve 241 has a first end and a second end in the axial direction, and the first end can press the variable-diameter locking ring 23. The first end is provided with a guide surface 2411 in the circumferential direction, and the guide surface 2411 is inclined to the inside of the sliding sleeve 241 in the direction from the second end to the first end. The guide surface 2411 is formed by chamfering the first end of the sliding sleeve 241, so as to thin the wall thickness of the first end of the sliding sleeve 241, so that the outer diameter of the first end of the sliding sleeve 241 is smaller than the maximum inner diameter of the variable-diameter locking ring 23, so that the first end of the sliding sleeve 241 is smoothly arranged in the inside of the variable-diameter locking ring 23, avoiding interference.

[0046] In the embodiment, the second end of the unlocking member 24 is provided with a fin 242 outside the shell 21. By arranging the fin 242, the operator can pull the fin 242 to drive the sliding sleeve 241 to reciprocate along the axial direction of the shell 21, so that the unlocking member 24 quickly reaches or leaves the unlocking position, further simplifying the disassembly operation of the connector assembly and improving the disassembly efficiency of the connector assembly.

[0047] As shown in Figure 4 , the second end is provided with at least two fins 242 equally spaced in the circumferential direction, the shell 21 is located between the outer periphery of the sliding sleeve 241 and the fin 242, and the circumferential side of the shell 21 is provided with at least two cut planes 2111, and the fin 242 is arranged opposite to the cut plane 2111. The second end of the sliding sleeve 241 is reversely bent to form at least two equally spaced fins 242, so as to pull the sliding sleeve 241 to reciprocate along the axial direction of the shell 21 through the at least two fins 242, thereby increasing the driving force of the unlocking member 24, improving the speed of the unlocking member 24 moving to the unlocking position, realizing the quick separation of the socket connector 1 and the plug connector 2, and improving the unlocking efficiency. At the same time, the fins 242 are equally spaced in the circumferential direction of the sliding sleeve 241, so that the sliding sleeve 241 moves uniformly in the axial direction of the shell 21, avoiding the sliding sleeve 241 from being stuck or deflected, and improving the stability and reliability of the unlocking process. In addition, by arranging the cut plane 2111, when the unlocking member 24 moves to the unlocking position along the axial direction of the shell 21 from left to right, the operator presses two fins 242 with two fingers respectively, the two fins 242 are tightly attached to the corresponding cut plane 2111 and slide along the corresponding cut plane 2111, thereby avoiding the unlocking member 24 from rotating circumferentially around the shell 21, further improving the stability and reliability of the unlocking process. The fin 242 of the embodiment is provided with two. In other embodiments, the fin 242 can be equally spaced with three or more than four, which is not limited here.

[0048] Further, the outer surface of the fin 242 is provided with a friction increasing structure 2421. As shown in Figure 4 , the outer surface of the fin 242 is provided with a plurality of convex strips to increase the friction between the operator's hand and the fin 242, so as to firmly press the fin 242, and further improve the stability and reliability of the unlocking process. In other embodiments, the outer surface of the fin 242 is provided with a plurality of grooves and other structures to increase the unevenness of the outer surface of the fin 242. The shape, number and mounting position of the convex strips or grooves and other friction reducing structures can be flexibly adjusted.

[0049] As shown in Figure 5As shown, the outer side of the sliding sleeve 241 is provided with a limiting groove 2412 in the circumferential direction, and the inner side of the shell 21 is correspondingly provided with a limiting protrusion 2121, which is slidingly arranged in the limiting groove 2412 to limit the limit position of the axial movement of the unlocking member 24 along the shell 21. Specifically, the inner side of the copper ring 212 is provided with the limiting protrusion 2121, which abuts against the left side wall of the limiting groove 2412 when the unlocking member 24 moves to the unlocking position; when the unlocking member 24 is farthest from the unlocking position, the limiting protrusion 2121 abuts against the right side wall of the limiting groove 2412 to limit the limit position of the axial movement of the unlocking member 24 along the shell 21, avoiding the unlocking member 24 from slipping out of the shell 21.

[0050] In the embodiment, one of the inner side of the sliding sleeve 241 and the outer side of the inner shell 11 is provided with a sliding groove 2413, and the other of the inner side of the sliding sleeve 241 and the outer side of the inner shell 11 is provided with a sliding block 112, which is slidingly matched with the sliding groove 2413. By setting the slidingly matched sliding block 112 and the sliding groove 2413, not only can the extension of the inner shell 11 into the shell 21 be guided, facilitating the quick plug-in assembly of the socket connector 1 and the plug connector 2, but also the relative circumferential rotation of the inner shell 11 and the shell 21 can be avoided, so that the pin 12 is accurately plugged into the plug 22, improving the plug-in precision of the socket connector 1 and the plug connector 2.

[0051] Specifically, as shown, Figure 2 the inner side of the sliding sleeve 241 is provided with the sliding groove 2413, and the outer side of the inner shell 11 is provided with the sliding block 112, which is slidingly matched with the sliding groove 2413.
