[0028] See also Figure 1-6 A short-circuit channel conversion connector with a sealed structure includes a socket and a plug that cooperate with each other. The socket serves as an external port and realizes short circuit between different pins through an internal structure. The plug serves as an operating end and cooperates with the socket. Under the rotation operation of the plug, the internal structure of the socket is driven to change; the socket includes a first shell 1 and a drive shaft 5. The drive shaft 5 is arranged in the first shell 1, and one end of the drive shaft 5 extends to the outside of the first shell 1 to cooperate with the plug. A conversion mechanism 2, a limiting mechanism 3, and a ratchet mechanism 4 are sequentially arranged on the drive shaft 5 in the first shell 1. The drive shaft 5 drives the conversion mechanism 2 to convert the line. The limiting mechanism 3 is used to limit the drive shaft 5 to prevent the line position conversion when the drive shaft 5 is accidentally touched. The ratchet mechanism 4 is used to make the drive shaft 5 jump at a fixed angle;

[0029] like Figure 5 As shown, the conversion mechanism 2 includes an insulating base, which is installed in the first housing 1. A contact 203 is provided at one end of the insulating base.

The fixed spring 202 is connected to the insulating base, and the movable spring 201 is sleeved on the driving shaft 5. When the driving shaft 5 rotates, it will drive the movable spring 201 to rotate, so that the movable spring 201 contacts different pins on the contact 203; as shown in FIG. Figure 6As shown in , the movable spring 201 of the conversion mechanism 2 rotates from the initial position to the final position, and the conversion of the circuit state is achieved by contacting different pins.

[0030] Specifically, the insulating base includes a lower cover plate 204, an intermediate body 205 and an upper cover plate 206, the contact member 203 is arranged at the outer end of the lower cover plate 204, and the other end of the contact member 203 is connected to the upper cover plate 206, and the upper cover plate 206 is located on one side of the limiting mechanism 3; the movable spring 201 is installed on the intermediate body 205, the intermediate body 205 is sleeved on the driving shaft 5, and the fixed spring 202 is installed on the inner side of the upper cover plate 206, wherein the movable spring 201 is arranged in two groups opposite to each other and installed on the side wall of the intermediate body 205, such as Figure 5 As shown in , the lower cover plate 204 and the upper cover plate 206 are both provided with a second protrusion, and the second protrusion cooperates with the inner wall of the first shell 1 to prevent the insulating base from rotating.

[0031] like Figure 4 As shown, the limiting mechanism 3 includes a limiting plate 301 and a positioning plate 302, the limiting plate 301 is sleeved on the driving shaft 5, the positioning plate 302 is installed on the inner wall of the first shell 1, the limiting plate 301 is sleeved in the positioning plate 302, the limiting plate 301 is rotatably connected to the positioning plate 302, a limiting groove 304 is provided on the positioning plate 302, the cross-section of the limiting groove 304 is a fan-shaped structure, a first protrusion 303 is provided on the limiting plate 301, and the first protrusion 303 extends into the limiting groove 304. Through the setting of the limiting groove 304, when the limiting plate 301 rotates to the final state position with the driving shaft 5, the limiting plate 301 will be blocked by the edge of the limiting groove 304, preventing the driving shaft 5 from further rotating, thereby protecting the circuit from damage and preventing line position conversion during misoperation.

[0032] like Figure 3 As shown, the ratchet mechanism 4 includes a wheel body 401 and a rotating member 402, the wheel body 401 is sleeved on the outer periphery of the rotating member 402, the rotating member 402 is sleeved on the driving shaft 5, the rotating member 402 can rotate with the driving shaft 5, a groove is provided on the rotating member 402, a first spring 403 is provided in the groove, a steel ball 404 is connected to the end of the spring, a ratchet groove is provided inside the wheel body 401, the steel ball 404 cooperates with the ratchet groove, and when the driving shaft 5 rotates, the steel ball 404 is driven to perform a fixed angle jump step under the elastic force of the first spring 403, and the movable spring 201 can rotate at a fixed angle through the angle equalization of the ratchet mechanism 4. The cooperation between the steel ball 404 and the first spring 403 ensures the accuracy and reliability of the circuit conversion, and in the absence of external force, the steel ball 404 will be stably maintained in the ratchet groove in the final state, ensuring the stability of the circuit.

[0033] In the present application, one end of the driving shaft 5 that cooperates with the plug is configured as a hexagonal prism structure, and the hexagonal prism structure can extend into the plug.

[0034] In this application, if Figure 2 As shown, the outer wall of the drive shaft 5 is provided with an annular groove and multiple groups of annular sealing grooves, a sealing ring 6 is arranged in the annular sealing groove to achieve sealing between the drive shaft 5 and the first shell 1, and a clamping ring 7 is arranged in the annular groove to limit the position of the drive shaft 5.

[0035] In the present application, a screw sleeve 8 and a locking sleeve 9 are further provided at one end of the outer side of the drive shaft 5. The locking sleeve 9 is located in a groove in the first housing 1. The screw sleeve 8 extends to the outer end of the first housing 1. The outer wall of the inner end of the screw sleeve 8 is connected to the inner wall of the first housing 1. The inner wall of the inner end of the screw sleeve 8 is connected to the outer wall of the locking sleeve 9. A plurality of screw sleeve slots 801 are provided at the outer end of the screw sleeve 8. The screw sleeve slots 801 are L-shaped structures.

[0036] like Figure 1 As shown, the plug includes a second housing 10, and a plurality of pins 12 are arranged on the outer side of one end of the second housing 10, and the pins 12 can cooperate with the screw sleeve slot 801. The pins 12 enter the screw sleeve slot 801, and the hexagonal prism structure end of the drive shaft 5 is inserted into the second housing 10 to achieve the connection between the plug and the socket.

[0037] In the present application, a push rod 14 is provided through one end of the pin 12 of the second housing 10, and the push rod 14 can contact the drive shaft 5, and an end cover 11 is provided at the other end of the second housing 10;

[0038] The push rod 14 is slidably matched with the second housing 10, and a second spring 13 is also arranged in the second housing 10, one end of the second spring 13 is connected to the push rod 14, and the other end of the second spring 13 is connected to the end cover 11. When the pin 12 enters the screw sleeve slot 801, the push rod 14 retreats under the push of the drive shaft 5, and the second spring 13 is compressed. At the same time, the elastic force of the second spring 13 pushes the push rod 14 to contact the drive shaft 5, so that the socket and the plug are connected stably.

[0039] Working principle: Figure 6As shown in , the common point a and the common point b represent two pins of the fixed spring piece 202, respectively, and I, II, III, and IV are four pins of the contact piece 203, respectively. In the initial state, the pins of the two movable spring pieces 201 are in contact with the pins I and III, respectively, and in the final state, the pins of the two movable spring pieces 201 are in contact with the pins II and IV, respectively; when the plug and the socket are separated (initial state), the line connection points are: I is connected to the common point a, and III is connected to the common point b. When the plug and the socket are plugged in and locked (final state), the line connection points are: II is connected to the common point a, and IV is connected to the common point b. During operation, the pin 12 enters the screw sleeve slot 801, and the push rod 14 retreats under the push of the drive shaft 5; the drive shaft 5 is driven by the rotation of the plug: the steel ball 404 of the ratchet mechanism 4 jumps from the ratchet slot in the initial state position to the slot in the final state under the action of the first spring 403, and will be fixed at this position without external force; the limiting mechanism 3 is intended to protect the circuit under the condition of misoperation. When the final state position is reached, if the drive shaft 5 continues to rotate, the limiting piece 301 will be blocked by the edge of the limiting slot 304, thereby not causing the circuit conversion; the movable spring piece 201 at the circuit conversion position is driven by the drive shaft 5 to change from the initial state position to the final state position; in the whole process, the upper part of the movable spring piece 201 is always in contact with the fixed spring piece 202, ensuring the continuity of the circuit, and the lower part of the movable spring piece 201 is in contact with the pin of the corresponding contact piece 203, realizing the conversion of the movable spring piece 201 from the initial state contact with the pins I and III to the final state contact with the pins II and IV.
