[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Please refer to Figure 1-Figure 7 The present embodiment provides a connector device, comprising: a male connector 10 and a female connector; the female connector comprises a body 20, a locking spring 30 and a locking buckle 40; the insertion end of the body 20 is recessed inward to form an insertion channel 201, and the locking spring 30 is arranged in the insertion channel 201; the locking spring 30 is provided with a locking channel 302 whose center line is colinear with the center line of the insertion channel 201, and a locking block 301 is provided on the side wall of the locking channel 302; a first opening 203 is provided on the side wall of the body 20, and the locking buckle 40 comprises a stop plate 401, and the stop plate 401 is inserted in the first opening 203.

[0060] The male connector 10 includes a column 101 and a stop flange 102 arranged outside the column 101; the column 101 is inserted into the insertion channel 201 from the insertion end, and the locking block 301 and the stop plate 401 abut against the side of the stop flange 102 facing the insertion end.

[0061] In this embodiment, the insertion channel 201 formed by the body 20 being recessed inwardly extends toward the connection end of the body 20 and penetrates the body 20. The connection end of the body 20 is connected to the first pipe, and the insertion channel 201 is communicated with the first pipe. The corresponding column 101 is provided with a flow guide channel penetrating the column 101. The column 101 is connected to the second pipe, and the flow guide channel is communicated with the second pipe. When the column 101 is inserted into the insertion channel 201, the flow guide channel on the column 101 is communicated with the insertion channel 201, and then the connection between the first pipe and the second pipe is realized through the female connector and the male connector 10.

[0062] Furthermore, a plurality of sealing rings are arranged at intervals in the insertion channel 201 near the connection end, and the column 101 has a sealing cylindrical surface located between the stop flange 102 and the front end of the column 101. When the column 101 is inserted into the insertion channel 201, the sealing cylindrical surface is connected to each sealing ring to improve the sealing between the column 101 and the insertion channel 201. The front end of the column 101 is the end of the column 101 that is away from the second pipe connection.

[0063] In this embodiment, the locking spring 30 arranged in the insertion channel 201 is connected to the insertion channel 201 to prevent the locking spring 30 from moving toward the insertion end of the insertion channel 201; after the column 101 is inserted into the insertion channel 201, the locking block 301 abuts against the side of the stop flange 102 facing the insertion end, thereby preventing the stop flange 102 from moving toward the insertion end, so as to prevent the column 101 from moving to the outside of the insertion channel 201, thereby preventing the male connector 10 from separating from the female connector.

[0064] In this embodiment, there can be multiple types of locking springs 30, as long as they can allow the stop flange 102 to pass through the locking spring 30 in the direction away from the insertion end when the column 101 is inserted into the insertion channel 201, and then the locking spring 30 prevents the column 101 from moving toward the insertion end. For example: the locking spring 30 also includes a first elastic rib 303, a second elastic rib 304 and a button 305, the abutting top of the first elastic rib 303 and the abutting top of the second elastic rib 304 are connected, and the abutting tops of the first elastic rib 303 and the second elastic rib 304 abut on the side wall of the insertion channel 201; the connecting end of the first elastic rib 303 and the connecting end of the second elastic rib 304 are both connected to the button 305, and the first elastic rib 303 and the second elastic rib 304 are surrounded by a locking channel 302; the locking block 301 is arranged on the first elastic rib 303 and / or the second elastic rib 304, and a slot 202 is arranged on the side wall of the insertion channel 201, and part of the locking block 301 is clamped in the slot 202; the body 20 is also provided with a second opening 206, and the abutting tops of the first elastic rib 303 and the second elastic rib 304 are inserted into the insertion channel 201 through the second opening 206. During installation, the column 101 is inserted into the insertion channel 201, and then the column 101 is inserted into the locking channel 302. When the stop flange 102 contacts the locking block 301, the locking block 301 is subjected to force and the first elastic rib 303 and the second elastic rib 304 are deformed in directions away from each other, so that the cross-sectional area of ​​the locking channel 302 increases, and the locking block 301 shrinks into the slot 202, and then the stop flange 102 passes through the locking channel 302; thereafter, under the action of the elastic force of the first elastic rib 303 and the second elastic rib 304 themselves, the first elastic rib 303 and the second elastic rib 304 return to their original state, so that the cross-sectional area of ​​the locking channel 302 is reduced, and the locking block 301 extends out of the slot 202 and abuts against the side of the stop flange 102 facing the insertion end to prevent the stop flange 102 from moving toward the insertion end. During disassembly, since the abutting ends of the first elastic rib 303 and the second elastic rib 304 are connected and both abut against the side wall of the insertion channel 201, and the connecting ends of the first elastic rib 303 and the second elastic rib 304 are both connected to the button 305, during disassembly, the first elastic rib 303 and the second elastic rib 304 can be deformed in directions away from each other by pressing the button 305, thereby causing the locking block 301 to shrink into the slot 202, the locking block 301 disengages from the stop flange 102, and the column 101 can be pulled out of the insertion channel 201 by pulling the column 101 toward the insertion end.

[0065] Furthermore, the locking block 301 can be arranged on the first elastic rib 303 or the second elastic rib 304; in a preferred implementation, the locking block 301 is arranged on both the first elastic rib 303 and the second elastic rib 304 to increase the contact area with the stop flange 102 to further prevent the stop flange 102 from detaching from the locking block 301.

[0066] Further, continue to refer to Figure 5 and Figure 6 The first elastic rib 303 and the second elastic rib 304 are provided with a protrusion 306 on their abutting tops, and a recess 207 is provided on the side wall of the insertion channel 201, and the protrusion 306 is accommodated in the recess 207. The protrusion 306 is accommodated in the recess 207, which can prevent the first elastic rib 303 and the second elastic rib 304 from moving in the insertion channel 201, thereby preventing the locking block 301 from being separated from the stop flange 102 due to the movement of the first elastic rib 303 and the second elastic rib 304 in the insertion channel 201.

[0067] In other implementations, the lock spring 30 may also have other structures, for example: the lock spring 30 includes a tubular body, the tube body has a locking channel whose center line is arranged in line with the center line of the insertion channel 201, an opening is opened on the side wall of the tube body, a locking block is arranged on the side of the opening facing the insertion end, the locking block can be integrally formed with the tube body, the locking block is inclined into the locking channel, and a locking block is arranged on the side of the locking block away from the locking channel; the tube body is inserted into the insertion channel 201, and the locking block on the locking block is snapped into the snapping block on the side wall of the insertion channel 201 The locking block is then moved into the locking channel until the stop flange 102 on the column 101 contacts the locking block, and the column 101 is continued to be moved into the locking channel. Under the abutment of the stop flange 102, the locking block is deformed toward the outside of the tube body, so that the stop flange 102 passes over the locking block. After that, the locking block is reset to the inside of the locking channel so that the locking block abuts against the side of the stop flange 102 facing the insertion end to prevent the column 101 from moving toward the insertion end.

[0068] In this embodiment, the first opening 203 and the locking block 301 provided on the main body 20 are in the same plane perpendicular to the center line of the insertion channel 201, so that when the stop plate 401 is inserted into the first opening 203, the stop plate 401 and the locking block 301 can simultaneously contact the side of the stop flange 102 facing the insertion end, so that the stop plate 401 and the locking block 301 can jointly prevent the stop flange 102 from moving toward the insertion end, thereby improving the connection force between the male connector 10 and the female connector.

[0069] Furthermore, an arc portion 4012 is formed at the front end of the stop plate 401 toward the insertion channel 201 . After the stop plate 401 is inserted into the first opening 203 , the center line of the arc portion 4012 is colinear with the center line of the column 101 to increase the contact area between the stop plate 401 and the stop flange 102 .

[0070] In this embodiment, a stop block 4011 is provided on the stop plate 401, and the stop block 4011 is used to abut against the side wall of the insertion channel 201 to prevent the stop block 4011 from moving outside the first opening 203. When the stop plate 401 is inserted into the insertion channel 201, the stop block 4011 abuts against the side wall of the insertion channel 201 to prevent the stop plate 401 from moving outside the insertion channel 201, thereby preventing the stop plate 401 from being separated from the stop flange 102 after installation.

[0071] The installation process of the connector device provided in this embodiment is as follows: first, the locking spring 30 is inserted into the insertion channel 201 through the second opening 206, and the locking block 301 on the first elastic rib 303 and / or the second elastic rib 304 is inserted into the slot 202 on the side wall of the insertion channel 201, and then the column 101 is inserted into the insertion channel 201 from the insertion end, and at the same time, the column 101 is inserted into the locking channel 302; when the stop flange 102 contacts the locking block 301, the first elastic rib 303 and the second elastic rib 304 are subjected to force, thereby causing the first elastic rib 303 and the second elastic rib 304 to move away from each other, and the locking block 301 moves into the slot 202 so that the stop flange 102 passes over the locking block 301. After that, under the elastic force of the first elastic rib 303 and the second elastic rib 304, the locking block 301 extends out of the slot 202, so that the locking block 301 abuts against the side of the stop flange 102 facing the insertion end to prevent the column 101 from moving to the outside of the insertion channel 201; then the stop plate 401 is inserted into the first opening 203, and at the same time, the stop plate 401 abuts against the side of the stop flange 102 facing the column 101 to further prevent the column 101 from moving to the outside of the insertion end, thereby completing the connection between the female connector and the male connector 10.

[0072] During disassembly, first pull out the stop plate 401 from the first opening 203, then press the button 305 on the lock spring 30 inward, so that the first elastic rib 303 and the second elastic rib 304 are deformed in directions away from each other, and the locking block 301 shrinks into the slot 202, thereby disengaging the locking block 301 from the stop flange 102. At this time, pull the column 101 toward the outside of the insertion channel 201, and pull the column 101 out of the insertion channel 201, thereby realizing the separation between the male connector 10 and the female connector.

[0073] In the connector device provided in this embodiment, the insertion end of the main body 20 is recessed inward to form an insertion channel 201, the locking spring 30 is arranged in the insertion channel 201, and a locking block 301 is arranged on the locking spring 30, and a first opening 203 is opened on the upper side wall of the main body 20; after the column 101 is inserted into the insertion channel 201, the locking block 301 on the locking spring 30 and the stop plate 401 on the lock buckle 40 inserted into the first opening 203 simultaneously press against the side of the stop flange 102 facing the insertion end, the locking spring 30 and the lock buckle 40 can jointly prevent the stop flange 102 from moving to the outside of the insertion channel 201, thereby improving the connection force between the male connector 10 and the female connector, and avoiding the separation of the male connector 10 and the female connector.

[0074] In this embodiment, the lock buckle 40 also includes a first leg 402 arranged at one end of the stop plate 401, and a first groove 4021 is arranged on the side wall of the first leg 402; a first slide 204 is arranged on the side wall of the main body 20, and the first leg 402 is inserted into the first slide 204, and a first protrusion 2041 is arranged at the end of the first slide 204; when the lock buckle 40 is in the initial position, part of the stop plate 401 is inserted into the insertion channel 201, and the end of the first leg 402 abuts against the first protrusion 2041 to prevent the first leg 402 from sliding toward the end of the first slide 204. Before installing the male connector 10, the first leg 402 can be inserted into the first slide 204 to put the lock 40 in the initial state, so that the lock 40 can be pre-installed. After the column 101 is inserted into the insertion channel 201, the lock 40 can be installed by simply pushing it inward, which simplifies the installation process and improves the assembly rate between the male connector 10 and the female connector. Further, in the initial position, the stop block 4011 on the stop plate 401 abuts against the side wall of the insertion channel 201, and the first leg 402 abuts against the first protrusion 2041. Under the clamping of the stop block 4011 and the first protrusion 2041, the first leg 402 is prevented from moving in the first slide 204, so as to prevent the stop plate 401 from being fully inserted into the first opening 203, thereby making it difficult to install the column 101, and at the same time, it can prevent the stop plate 401 from being separated from the body 20. It should be noted that, when in the initial position, a portion of the stop plate 401 is inserted into the insertion channel 201 , but the stop plate 401 located in the insertion channel 201 does not affect the passage of the column 101 and the stop flange 102 .

[0075] In this embodiment, a first protrusion 4022 is also provided on the first leg 402, and a first through hole penetrating into the insertion channel 201 is opened on the side wall of the first slide. When the lock buckle 40 is in the initial position, the first protrusion 4022 extends into the insertion channel 201 through the first through hole; and when the column 101 is inserted into the insertion channel 201, the stop flange 102 presses against the first protrusion 4022 to disengage the end of the first leg 402 from the first protrusion 4022. During installation, the column 101 is inserted into the insertion channel 201, and the stop flange 102 presses against the first protrusion 4022 to disengage the first protrusion 4022 from the first groove 4021, so as to prevent the first protrusion 4022 from being stuck in the first groove 4021 and thereby preventing the first leg 402 from being pushed into the first slide 204; in addition, when the first protrusion 4022 disengages from the first groove 4021, the end of the first leg 402 disengages from the first protrusion 4022.

[0076] Furthermore, when the lock buckle 40 is in the assembly position, the stop plate 401 is completely inserted into the insertion channel 201, and the first protrusion 2041 is clamped in the first groove 4021. The assembly position is the position of the lock buckle 40 when the stop plate 401 abuts against the side of the stop flange 102 facing the insertion end; the first groove 4021 cooperates with the first protrusion 2041 to prevent the first leg 402 from moving in the first slideway 204, causing the stop plate 401 in the assembly position to move toward the outside of the first opening 203, thereby preventing the stop plate 401 from separating from the stop flange 102.

[0077] Furthermore, a fitting portion 404 is provided on the first leg 402, and a stop hole is provided on the side wall of the first slideway 204; when the lock buckle 40 is in the assembly position, the fitting portion 404 extends from the stop hole into the insertion channel 201 to push against the lock block 301 in the insertion channel 201. When the lock buckle 40 is in the assembly state, the fitting portion 404 can push against the lock block 301 in the insertion channel 201 to prevent the lock block 301 from separating from the stop flange 102. Specifically, the stop hole and the first through hole can be the same hole to reduce the number of holes opened on the body 20; of course, the stop hole and the first through hole can also be different holes.

[0078] In this embodiment, the lock buckle 40 further includes a second leg 403 disposed opposite to the first leg 402, and a second groove 4031 is disposed on the side wall of the second leg 403; a second slideway 205 is disposed on the side wall of the body 20, and the second leg 403 is inserted into the second slideway 205, and a second protrusion 2051 is disposed at the end of the second slideway 205; when the lock buckle 40 is in the initial position, the end of the second leg 403 abuts against the second protrusion 2051. This can further prevent the lock buckle 40 from moving.

[0079] Furthermore, a second protrusion 4032 is also provided on the second leg 403, and a second through hole penetrating to the insertion channel 201 is opened on the side wall of the second slide groove. When the lock buckle 40 is in the initial position, the second protrusion 4032 extends into the second through hole; and when the column 101 is inserted into the insertion channel 201, the stop flange 102 presses against the second protrusion 4032 to disengage the second groove 4031 from the second protrusion 4032.

[0080] In this embodiment, when the lock buckle 40 is in the assembly position, the second protrusion 2051 is locked in the second groove 4031. The second groove 4031 cooperates with the second protrusion 2051 to further prevent the lock buckle 40 from moving, causing the stop plate 401 to move out of the first opening 203, further preventing the stop plate 401 from separating from the stop flange 102.

[0081] In a preferred implementation, the lock spring 30 includes two locking blocks 301 arranged opposite to each other, and a fitting portion 404 is also provided on the corresponding second leg 403. Two stop holes are arranged opposite to each other on the main body 20. When the lock buckle 40 is in an assembled state, the fitting portion 404 on the first leg 402 and the fitting portion 404 on the second leg 403 extend into the insertion channel 201 through different stop holes. The fitting portion 404 on the first leg 402 abuts against one locking block 301, and the fitting portion 404 on the second leg 403 abuts against the other locking block 301 to prevent the locking block 301 from separating from the stop flange 102.

[0082] In the above implementation, the installation process of the connector device is: first, insert the locking spring 30 into the insertion channel 201 through the second opening 206, and make the locking block 301 on the first elastic rib 303 and the second elastic rib 304 snap into the slot 202 on the side wall of the insertion channel 201; then insert the first leg 402 into the first slide 204, so that the end of the first leg 402 abuts against the first protrusion 2041, and at the same time, the end of the second leg 403 abuts against the second protrusion 2051, so that the lock buckle 40 is in the initial position, completing the pre-installation of the female connector. Then, the column 101 is inserted into the insertion channel 201 from the insertion end, and at the same time, the column 101 is inserted into the locking channel 302, and the stop flange 102 contacts the locking block 301, which causes the first elastic rib 303 and the second elastic rib 304 to be stressed, thereby causing the first elastic rib 303 and the second elastic rib 304 to move in directions away from each other, and the locking block 301 moves into the slot 202 so that the stop flange 102 passes over the locking block 301, and then, the first elastic rib 303 and the second elastic rib 304 are in contact with each other. 4, the locking block 301 extends out of the card slot 202, so that the locking block 301 abuts against the side of the stop flange 102 facing the insertion end to prevent the column 101 from moving to the outside of the insertion channel 201; thereafter, the column 101 continues to be pushed into the insertion channel 201, and the stop flange 102 contacts the first protrusion 4022 and the second protrusion 4032, thereby causing the end of the first leg 402 to disengage from the first protrusion 2041, and the end of the second leg 403 to disengage from the second protrusion 2051. Then, the lock buckle 40 is pushed inward to make the first groove 4021 engage with the first protrusion 2041, and the second groove 4031 engage with the second protrusion 2051, and the lock buckle 40 is in an assembled state; at the same time, the stop plate 401 presses against the side of the stop flange 102 facing the column 101 to further prevent the column 101 from moving toward the outside of the insertion end; in addition, the fitting portion 404 on the first leg 402 and the fitting portion 404 on the second leg 403 fit with different locking blocks 301 and press the locking block 301 toward the inside of the insertion channel 201. At this time, even if the button 305 on the locking spring 30 is pressed, the locking block 301 will not be separated from the stop flange 102 under the pressure of the fitting portion 404, thereby completing the connection between the female connector and the male connector 10.

[0083] During disassembly, first disengage the first groove 4021 from the first protrusion 2041, disengage the second groove 4031 from the second protrusion 2051, and then pull out the lock buckle 40 until the lock buckle 40 is in the initial position; at this time, the stop plate 401 is disengaged from the stop flange 102, and the fitting portion 404 on the first leg 402 and the second leg 403 is separated from the locking block 301; then press the button 305 on the locking spring 30 to deform the first elastic rib 303 and the second elastic rib 304 in directions away from each other, and the locking block 301 moves into the slot 202, thereby separating the locking block 301 from the stop flange 102, and at this time, pull the column 101 toward the outside of the insertion channel 201, so that the column 101 can be pulled out of the insertion channel 201, thereby realizing the separation between the male connector 10 and the female connector.
