DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] like Figure 1-Figure 3 As shown, a quick-plug type radio frequency connector proposed in one embodiment of the present application includes:

[0025] A male end 1 is provided with a plug-in block 2, which is fixed on the male end 1 and coaxially distributed therewith, the plug-in block 2 is annular in structure, and a limiting groove 3 with a V-shaped cross-sectional structure is provided on the plug-in block 2, the limiting groove 3 is annular in structure and coaxially distributed with the plug-in block 2;

[0026] The female end 4 is provided with a plug-in groove 5 and an annular groove 6, the plug-in block 2 is plugged into the plug-in groove 5, and the female end 4 is provided with a plurality of elastic limiters that act on the limiter groove 3, which are used to lock or unlock the plug-in block 2, and the plurality of elastic limiters are distributed in an annular array, and a limiter that acts on the plurality of elastic limiters is provided in the annular groove 6, which is used to lock or unlock the elastic limiter;

[0027] In the initial state, the male end 1 and the female end 4 are separated, and the multiple elastic limit members are in a natural state. The multiple elastic limit members are locked by the limit part. When connecting, the multiple elastic limit members are unlocked by the limit part, so that the plug-in block 2 corresponds and is completely inserted into the plug-in slot 5 until the male end 1 and the female end 4 are in contact and overlap. In this process, the plug-in block 2 and the multiple elastic limit members are in contact and overlap, forcing the multiple elastic limit members to move synchronously away from the axis of the female end 4. The multiple elastic limit members are in a squeezed state, and then the multiple elastic limit members are reset to the natural state and close to the axis of the female end 4. The plurality of elastic limiting members all act on the limiting groove 3, and then the plurality of elastic limiting members are locked by the limiting part, so that the plurality of elastic limiting members cannot move, and the plug-in block 2 cannot withdraw from the plug-in groove 5, that is, the male end 1 and the female end 4 cannot be separated, and the connection is completed. On the contrary, during disassembly, the plurality of elastic limiting members are unlocked by the limiting part, so that the plug-in block 2 withdraws from the plug-in groove 5. In this process, the plurality of elastic limiting members are first forced to move synchronously to the axis away from the female end 4, and then the plurality of elastic limiting members are reset to the natural state and close to the axis of the female end 4, and then the plurality of elastic limiting members are locked by the limiting part;

[0028] To sum up, the present application abandons the threaded connection method between the male end 1 and the female end 4 in the prior art, and adopts a quick-insert structure to achieve the connection between the male end 1 and the female end 4. There is no need to repeatedly tighten and loosen during loading and unloading. While facilitating operation, it also avoids the situation where loading and unloading cannot be caused by thread slippage, and is therefore more practical.

[0029] like Figure 2-Figure 3 As shown, in some embodiments, a positioning groove 7 communicating with the plug-in groove 5 is provided on the female end 4, and a positioning block 8 plugged with the positioning groove 7 is provided on the plug-in block 2, and the positioning block 8 is fixed on the outer surface of the plug-in block 2;

[0030] Referring to the above, when the plug-in block 2 corresponds to and is fully inserted into the plug-in slot 5, the positioning block 8 corresponds to and is fully inserted into the positioning slot 7, which not only enables rapid positioning during connection, but also prevents relative rotation between the male end 1 and the female end 4 after connection, thereby improving connection stability.

[0031] like Figure 2-Figure 3 As shown, in some embodiments, a seal is provided between the male end 1 and the female end 4;

[0032] Referring to the above, when the male end 1 and the female end 4 are connected, the sealing member can improve the sealing between the two to achieve a waterproof effect.

[0033] like Figure 2-Figure 3 As shown, in some embodiments, the seal includes a sealing groove 9 which is formed in an annular shape and is opened on the female end 4, the sealing groove 9 is coaxially distributed with the female end 4, and a sealing ring 10 which is plugged and matched with the sealing groove 9 is provided on the male end 1, the sealing ring 10 is fixed on the male end 1 and coaxially distributed with the male end 1, and a guiding inclined surface is constructed on the sealing ring 10;

[0034] Referring to the above, when the plug-in block 2 corresponds to and is fully inserted into the plug-in groove 5, the sealing ring 10 corresponds to and is fully inserted into the sealing groove 9. Through the cooperation of the sealing ring 10 and the sealing groove 9, the sealing performance when the male end 1 and the female end 4 are connected is improved. The design of the guiding slope facilitates the sealing ring 10 to enter the sealing groove 9.

[0035] like Figure 5As shown, in some embodiments, the elastic limiter includes a movable groove 11 provided on the female end 4, the two ends of the movable groove 11 are respectively connected to the plug-in groove 5 and the annular groove 6, and a triangular block 12, a slide rod 13 and an arc plate 14 connected in sequence are slidably arranged in the movable groove 11, the triangular block 12, the slide rod 13 and the arc plate 14 are fixedly connected in sequence and form a step-like structure, the sliding directions of the triangular block 12, the slide rod 13 and the arc plate 14 are all perpendicular to the axis of the female end 4, the triangular block 12 is plugged and matched with the limiter groove 3, and a reset spring 15 sleeved on the slide rod 13 is arranged between the triangular block 12 and the movable groove 11, the two ends of the reset spring 15 are respectively fixedly connected to the triangular block 12 and the movable groove 11, and the limiter is used to lock or unlock the arc plate 14;

[0036] Referring to the above, in the initial state, the reset spring 15 is in a natural state, the triangular block 12 is completely located in the plug-in slot 5, the arc plate 14 is completely located in the movable slot 11, and the arc plate 14 is locked by the limit portion. When connected, the arc plate 14 is unlocked by the limit portion. When the plug-in block 2 corresponds to and is completely plugged into the plug-in slot 5, the plug-in block 2 and the triangular block 12 are in contact and overlapped. Through the transition effect of the inclined surface, the triangular block 12 is forced to completely enter the movable slot 11, the reset spring 15 is squeezed, and the arc plate 14 completely withdraws from the movable slot 11 and enters the annular slot 6. Then the reset spring 15 is released. The spring 15 is reset to a natural state, the triangular block 12 completely enters the limit groove 3, the arc plate 14 re-enters the movable groove 11, and then the arc plate 14 is locked by the limit portion, so that the arc plate 14 cannot slide, that is, the triangular block 12 cannot withdraw from the limit groove 3, and the plug-in block 2 cannot withdraw from the plug-in groove 5, so as to lock the plug-in block 2. Conversely, the arc plate 14 is unlocked by the limit portion, and the plug-in block 2 can withdraw from the plug-in groove 5. In this process, the triangular block 12, the arc plate 14 and the reset spring 15 all repeat the above-mentioned movement state, and finally the arc plate 14 is locked by the limit portion.

[0037] like Figure 5-Figure 6 As shown, in some embodiments, the limiting portion includes a ring plate 16 slidably disposed in the annular groove 6, a compression spring 17 is disposed between the ring plate 16 and the annular groove 6, and both ends of the compression spring 17 are respectively fixedly connected to the ring plate 16 and the annular groove 6, and the ring plate 16 and the arc plate 14 are in contact and overlapped;

[0038] Referring to the above, in the initial state, the squeezing spring 17 is in a natural state, the ring plate 16 is in the initial position and is in contact with and overlaps the arc plate 14. Due to the obstruction of the ring plate 16, the arc plate 14 cannot slide, so as to lock the arc plate 14, drive the ring plate 16 to slide away from the initial position, and the squeezing spring 17 is squeezed. Due to the loss of the obstruction of the ring plate 16, the arc plate 14 can slide, thereby unlocking the arc plate 14. Conversely, the ring plate 16 is released, and the squeezing spring 17 is reset to the natural state. The ring plate 16 slides to the initial position due to elastic potential energy and is in contact with and overlaps the arc plate 14 again, thereby locking the arc plate 14 again.

[0039] like Figure 6 As shown, in some embodiments, a locking member is provided on the ring plate 16 and the female end 4, and the ring plate 16 is locked or unlocked by the locking member;

[0040] Referring to the above, when connecting, the ring plate 16 slides away from the initial position. During this process, the ring plate 16 is locked by the locking member, so there is no need to maintain the position of the ring plate 16, which facilitates subsequent operations. When the plug-in block 2 corresponds to and is fully inserted into the plug-in slot 5, the ring plate 16 is unlocked by the locking member, and the ring plate 16 slides to the initial position due to elastic potential energy.

[0041] like Figure 6 As shown, in some embodiments, the locking member includes a fixed column 18 arranged on the ring plate 16, the fixed column 18 is fixed on the ring plate 16 and is perpendicular to the axis thereof, an elastic rod 19 is arranged on the fixed column 18, the elastic rod 19 is fixed on the fixed column 18 and is perpendicular to the fixed column 18, a tapered block 20 is arranged at the free end of the elastic rod 19, the tapered block 20 is fixedly connected to the elastic rod 19, a door-shaped plate 21 is arranged on the female end 4, the door-shaped plate 21 is configured with a perforation, and the tapered block 20 and the door-shaped plate 21 are in contact and overlapped;

[0042] Referring to the above, in the initial state, the elastic rod 19 is in a natural state, and the conical block 20 is away from the door-shaped plate 21. When connected, the ring plate 16 slides away from the initial position, driving the fixed column 18, the elastic rod 19 and the conical block 20 to move together. In this process, the conical block 20 enters the through hole, and the inclined surface of the conical block 20 first contacts and overlaps with the door-shaped plate 21. Through the transition effect of the inclined surface, the elastic rod 19 is forced to undergo elastic deformation. Then the conical block 20 completely passes through the through hole, and the elastic rod 19 is reset to a natural state. The plane of the conical block 20 contacts and overlaps with the door-shaped plate 21, thereby locking the ring plate 16. Conversely, pressing the conical block 20 forces the elastic rod 19 to undergo elastic deformation. The ring plate 16 slides to the initial position due to elastic potential energy, driving the conical block 20 to withdraw from the through hole, and then the elastic rod 19 is reset to a natural state, thereby unlocking the ring plate 16.
