Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention as defined and defined by the appended claims, and all changes that can be made by the invention using the inventive concept are intended to be protected.
Referring to fig. 1, fig. 1 shows an exploded view of a plug 3 and a receptacle 1 when locked; as shown in fig. 1, the circular quick-lock connector comprises a plug 3 and a socket 1, wherein the plug 3 and the socket 1 are fixedly connected through a locking structure.
As shown in fig. 1, 5 and 6, the locking structure includes a connecting portion 2, a plurality of protrusions 311 provided on an outer surface of the header 3 adjacent to the socket 1, an arc-shaped groove 312 provided on an outer surface of the header 3 adjacent to the protrusions 311, and a plurality of protrusions 111 provided on an outer surface of the socket 1 adjacent to the header 3.
As shown in fig. 2 to 5, the connecting portion 2 includes a snap ring 22 and a connection ring 21 sleeved on an end portion of the plug 3; the inner surface of the snap ring 22 is provided with at least one radially extending snap groove 221; the end of the connection ring 21 adjacent to the protrusion 311 has an annular step 212, the annular step 212 is provided with a plurality of positioning posts 213 engaged with the locking slots 221, and the locking slots 221 are internally provided with springs 23 contacting the protrusion 311 and having a length greater than that of the locking slots 221.
As shown in fig. 5, after the positioning pillars 213 are disposed on the annular step 212, all the positioning pillars 213 and the inner surface of the connection ring 21 form a groove body with a plurality of openings, the annular structure portion of the snap ring 22 is installed in the groove body, the clamping groove 221 portion of the snap ring 22 is located on the annular step 212 outside the groove body, and one side of the clamping groove 221 contacts with the positioning pillars 213.
As shown in fig. 2, the inner surface of the end of the connection ring 21 away from the protrusion 311 is provided with a locking groove 211 for locking the socket 1 with the protrusion 111; the locking groove 211 comprises a channel with a side wall being a guide inclined surface 2111 and gradually reduced in width, and a limiting groove 2112 which is larger than the width of the root of the channel and extends towards the direction of the guide inclined surface 2111;
after the plug 3, the connection ring 21, the snap ring 22 and the spring 23 are assembled together, the end part of the spring 23 which is not positioned in the clamping groove 221 contacts with the projection 311 on the plug 3, and at the moment, the spring 23 is in a partial compression state (does not reach the maximum compression deformation) or in a free state; the stopper groove 2112 of the coupling ring 21 extends in the same direction as the compressive force applied to the spring 23, and the guide slope 2111 is inclined in the opposite direction to the compressive force applied to the spring 23.
The following describes the movement of the components when assembling the connector according to this embodiment:
when the plug 3 and the socket 1 are butted, the convex part 111 on the socket 1 is aligned with the locking groove 211 on the connecting ring 21, the plug 3 and the socket 1 are pushed by force, the convex part 111 on the socket 1 slides along the guide inclined surface 2111, so that the connecting ring 21 moves towards the direction opposite to the movement of the convex part 111, and meanwhile, the convex block 311 on the plug 3 utilizes the compression spring 23 to provide elasticity, so that the spring 23 is gradually compressed; when the plug 3 and the socket 1 move in place, namely the plug 3 and the socket 1 do not move relatively, the plug 3 and the socket 1 are loosened, and the spring 23 recovers deformation, the spring 23 releases elasticity to push the connection ring to rotate, so that the 2112 of the connection ring is clamped on the convex part 111 of the socket 1, and the convex part 111 on the socket 1 is stably clamped in the limiting groove 2112.
It can be seen from the above description of the assembly of the plug 3 and the socket 1 that, in this solution, when the plug 3 and the socket 1 are butted, the connection ring 21 does not need to be rotated, and the connection ring 21 on the plug 3 can be automatically rotated to lock the socket 1 by directly pushing in the plug 3, so as to achieve the quick locking function.
During assembly, the socket 1 and the plug 3 can be installed in place by using small force, the pushing force is appropriate, and the operation is convenient and labor-saving. When the quick locking is realized, the connecting ring 21 does not need to be manually rotated to lock the socket 1, and the structure solves the problems that the operation is inconvenient and even the installation cannot be carried out at a place with a smaller installation space.
As shown in fig. 8, a spring collar 24 is mounted in arcuate slot 312 extending partially to the lower surface of annular step 212 for limiting axial movement of the connector ring 21 in the connector.
Due to the elasticity of the spring collar 24, after the connection ring 21 is mounted on the plug 3, and after the spring collar 24 is restored, the spring collar 24 is located on the lower surface of the annular step 212 of the connection ring 21, i.e. the spring collar 24 extends partially to the annular step 212 and partially lies in the arc-shaped groove 312. In the axial direction of the connector, the connection ring 21 is stably fixed on the plug 3 due to the blocking action of the spring collar 24, and the socket 1 is retained by the connecting portion 2, thereby finally achieving stable connection between the plug 3 and the socket 1.
As shown in fig. 2, the slope of the guide slope 2111 may be appropriately adjusted according to the elastic force of the spring 23, and when the elastic force of the spring 23 is large, the slope of the guide slope 2111 may be set to a small point, and when the elastic force of the spring 23 is large, the slope of the guide slope 2111 may be set to a large point.
When the inclination of the guide slope 2111 is small, the locking groove 211 formed by the limiting groove 2112 and the channel is substantially L-shaped; when the slope of the guide slope 2111 is large, the locking groove 211 formed by the stopper groove 2112 and the passage is substantially R-shaped.
As shown in fig. 4, the clamping groove 221 includes an extension wall disposed on an end surface of one side of the snap ring 22 and an L-shaped side wall disposed on an end surface of the other side of the snap ring 22 and offset from the extension wall, and the extension wall and the L-shaped side wall make the clamping groove 221 arc-shaped.
Because the width and the thickness of the snap ring 22 are both limited, after the clamping groove 221 adopts the structure, the normal clamping of the spring 23 is ensured, the processing is very convenient, and the weight and the material cost of the snap ring 22 are reduced.
The spring 23 may be arc-shaped or straight; when the spring 23 is straight, the spring 23 fitted into the groove 221 of the snap ring 22 is restrained in an arc state by the protrusion 111 and the positioning post 213.
As shown in fig. 8, in an embodiment of the present invention, the plug 3 includes a plug housing 31 having a step shape, a step hole penetrating through the plug housing 31 is formed in the plug housing 31, and a pin 34 extending out of the front positioning plate 33 is fixedly installed in the step hole through a rear positioning plate 32 and a front positioning plate 33; the pins 34 are composed of positioning portions between the rear positioning plate 32 and the front positioning plate 33 and columnar extensions partially extending out of the front positioning plate 33.
As shown in fig. 7, in an embodiment of the present invention, the socket 1 includes a socket housing 11 having an annular flange at the middle, a through hole penetrating through the socket housing 11 is formed in the socket housing 11, and a convex ring is formed at the middle of the through hole; a jack 14 is fixedly arranged in the through hole through a rear positioning block 13 and a front positioning block 12; the insertion hole 14 is composed of a positioning section having a hole body for receiving the insertion pin 34 installed in the rear positioning block 13 and a cylindrical section partially extending out of the rear positioning block 13.
During the implementation, the preferred back locating plate 32 of this scheme is installed in the great side of step hole diameter, and front locating plate 33 one end is provided with the arch that clamps in the great side of step hole diameter, and the other end has the sleeve that leads jack 14, and telescopic height is greater than the length that contact pin 34 extends front locating plate 33.
As shown in fig. 9, the circular quick-lock connector further comprises a sealing assembly 4 fixedly arranged at the end of the plug 3 far away from the socket 1; the sealing assembly 4 comprises a sealing shell 41 which is clamped at the end part of the plug 3 far away from the socket 1, a sealing member 42 which is arranged at the inner surface of the contact section of the sealing shell 41 and the socket 1, and a cover 43 which is arranged in the sealing member 42 in an interference fit manner.
In conclusion, when the plug 3 and the socket 1 are locked, the characteristics of blind insertion, rapidness, convenience and reliable connection are realized, when the plug 3 is inserted into the socket 1 for locking, the plug can be locked only by forward pushing, the plug is firm and reliable, and other actions such as rotating a locking sleeve are not needed.
