[0030] Reference Figures 1 to 3 The embodiment of the utility model provides a connector with a stop mechanism, including a first housing 100, a second housing and a connection cap 200. The outer wall of the first housing 100 is provided with a stop block 110, the stop block 110 includes a first convex portion 120 and a second convex portion 130, a fixing groove 140 is formed between the first convex portion 120 and the second convex portion 130, the first convex portion 120 and the second convex portion 130 extend in a direction away from the center line of the first housing 100, respectively, and along the radial direction of the first housing 100, the height of the first convex portion 120 is greater than the second convex portion 130. The outer wall of the second housing is provided with a block, and the second housing is provided with a first mark, and the first mark is located on the outer peripheral wall of the second housing.

[0031] Reference Figure 4, in some embodiments of the present utility model, the connection cap 200 is sleeved on the outer wall of the first housing 100, and the connection cap 200 is rotatably connected to the first housing 100. A guide groove 210 is provided on the inner wall of the connection cap 200. The guide groove 210 is provided with an inlet 211. The guide groove 210 is spirally arranged on the inner wall of the connection cap 200. The clamping block can enter the guide groove 210 from the inlet 211, and the clamping block can move along the guide groove 210, that is, the clamping block is rotatably connected to the guide groove 210. By rotatably connecting the clamping block of the connection cap 200 to the guide groove 210, the connection cap 200 is connected to the second housing, and further the first housing 100 and the second housing are connected. A flexible block 220 is provided on the inner wall of the connection cap 200. The flexible block 220 extends along the direction close to the center line of the connection cap 200. Rotate the connection cap 200, and the flexible block 220 contacts the side of the second convex portion 130 facing away from the first convex portion 120. Continue to rotate the connection cap 200, and the flexible block 220 can be deformed under extrusion so that the flexible block 220 enters the fixing groove 140 and is buckled in the fixing groove 140.

[0032] It can be understood that the flexible block 220 is buckled in the fixing groove 140, so that the connection cap 200 is fixed to the first housing 100, and further the relative position of the connection cap 200 and the first housing 100 is fixed. When the first mark corresponds to the second mark 240, the clamping block corresponds to the inlet 211, and there is no need to rotate the connection cap 200 to align the clamping block with the inlet 211, which improves the connection efficiency and installation convenience of the first housing 100 and the second housing, and facilitates the installation of the first housing 100 and the second housing. When the clamping block corresponds to the inlet 211, rotate the connection cap 200 so that the clamping block slides along the guide groove 210, thereby connecting the first housing 100 and the second housing. Along the radial direction of the first housing 100, the height of the first convex portion 120 is greater than that of the second convex portion 130 to limit the rotation direction of the connection cap 200, which is beneficial to simplify the operation. At the same time, when the flexible block 220 is buckled in the fixing groove 140, it is prevented that the connection cap 200 continues to rotate and the flexible block 220 crosses the first convex portion 120 and disengages from the fixing groove 140.

[0033] It can be understood that the flexible block 220 can be deformed. When rotating the connection cap 200 to make the flexible block 220 enter the fixing groove 140, the flexible block 220 abuts against and moves along the side wall of the second convex portion 130 towards the direction close to the first convex portion 120, and the flexible block 220 is deformed so that the flexible block 220 enters the fixing groove 140. When rotating the connection cap 200 to make the flexible block 220 disengage from the fixing groove 140, the flexible block 220 abuts against and moves along the side wall of the second convex portion 130 towards the direction away from the first convex portion 120, and the flexible block 220 is deformed so that the flexible block 220 disengages from the fixing groove 140. The material of the flexible block 220 can be plastic, or polymer material, etc. The material of the flexible block 220 can be selected according to actual production applications, and the present application does not limit this here.

[0034] Reference Figure 3 In some embodiments of the utility model, a first arc surface 131 is provided on the outer side of the second protrusion 130, and the first arc surface 131 is located on the side of the second protrusion 130 away from the fixing groove 140. The first arc surface 131 can guide the flexible block 220 to enter the fixing groove 140 from the side of the second protrusion 130 away from the first protrusion 120, so as to facilitate the flexible block 220 to be buckled in the fixing groove 140 and reduce the friction between the flexible block 220 and the fixing groove 140.

[0035] Reference Figure 3 In some embodiments of the utility model, the second protrusion 130 is provided with a second arc surface 132, and the two ends of the second arc surface 132 are respectively connected to the wall surface of the fixing groove 140 and the first arc surface 131. When the connecting cap 200 is rotated to make the flexible block 220 disengage from the fixing groove 140, the flexible block 220 moves along the second arc surface 132. The second arc surface 132 can guide the flexible block 220 to disengage from the fixing groove 140 from the second protrusion 130, making it easier for the flexible block 220 to disengage from the fixing groove 140. When the flexible block 220 disengages from the fixing groove 140, the friction between the flexible block 220 and the second protrusion 130 is reduced.

[0036] Reference Figure 3 It can be understood that the outer wall of the flexible block 220 has a curved surface to facilitate the flexible block 220 to enter and escape from the fixing groove 140, further reducing the wear between the flexible block 220 and the second protrusion 130.

[0037] Reference Figure 2 In some embodiments of the present invention, at least three stopper blocks 110 are provided, and at least three stopper blocks 110 are arranged at intervals along the circumference of the first shell 100, at least three flexible blocks 220 are provided, and at least three flexible parts are arranged at intervals along the circumference of the connection cap 200, and at least three flexible blocks 220 are correspondingly arranged in at least three stopper blocks 110. By providing at least three stopper blocks 110 and flexible blocks 220 respectively along the circumference of the first shell 100, the connection between the connection cap 200 and the shell is more firmly secured.

[0038] Reference Figure 5 In some embodiments of the utility model, a connector with a stopping mechanism is provided with a wave spring 300, the outer wall of the first shell 100 is provided with a first mounting groove 150, the inner wall of the connecting cap 200 is provided with a second mounting groove 230, and the wave spring 300 is located in the first mounting groove 150 and the second mounting groove 230 to limit the movement of the connecting cap 200 in the axial direction of the first shell 100, so as to fix the connecting cap 200 in the axial direction relative to the first shell 100.

[0039] Reference Figure 5, in some embodiments of the present utility model, along the circumferential direction of the connection cap 200, the second mark 240 corresponds to the flexible block 220. When the connection cap 200 is connected to the first housing 100, by the second mark 240 corresponding to the flexible block 220, it is convenient to observe the position of the flexible block 220, which facilitates the connection of the connection cap 200 to the first housing 100 and improves the installation convenience of the connection cap 200.

[0040] Refer to Figure 4 , in some embodiments of the present utility model, a positioning block 160 is provided on the outer wall of the first housing 100, and a positioning groove is provided on the inner wall of the second housing. When the first housing 100 is connected to the second housing, the positioning block 160 is located in the positioning groove. By the positioning block 160 being located in the positioning groove, the installation positioning of the first housing 100 and the second housing is achieved.

[0041] Refer to Figure 4 , in some embodiments of the present utility model, when the flexible block 220 is snap-fitted into the fixing groove 140, the second mark 240 corresponds to the positioning block 160. The first mark corresponds to the positioning groove. When the first mark corresponds to the second mark 240, the fixing block corresponds to the fixing groove 140, which improves the connection efficiency and installation convenience of the first housing 100 and the second housing.

[0042] Refer to Figure 4 , in some embodiments of the present utility model, the guide grooves 210 are spirally arranged on the inner wall of the connection cap 200. There are at least three guide grooves 210, and there are at least three clamping blocks. At least three clamping blocks respectively correspond to at least three guide grooves 210. By respectively providing at least three clamping blocks and clamping grooves, the connection between the connection cap 200 and the second housing is made more stable.

[0043] Refer to Figure 4 , in some embodiments of the present utility model, the guide groove 210 communicates with a fixing section 212, and the clamping block can be snap-fitted into the fixing section 212 so that the clamping block is fixed in the guide groove 210.

[0044] It can be understood that along the axial direction of the connection cap 200, the fixing section 212 extends away from the second housing. The clamping block slides along the guide groove 210, and the connection cap 200 compresses the corrugated spring; when the clamping block moves to the fixing section 212, under the elastic force of the corrugated spring, the clamping block is snap-fitted into the fixing section 212 to prevent the clamping block from sliding out of the fixing section 212, thereby avoiding the clamping block from sliding out of the guide groove 210.
