The plug-in slot 2212 is used for plugging in the pin terminal 33. Generally, a hole is also provided at the end of the pin terminal 33 for plugging in the plug-in slot 2212. When the pin terminal 33 is plugged into the plug-in slot 2212, the plug-in column 222 can be plugged into the hole of the pin terminal 33. The plug-in cooperation between the plug-in column 222 and the hole plays a limiting role, which can limit the pin terminal 33 from swinging in the plug-in slot 2212.

In a specific embodiment, the plug-in slot 2212 is cylindrical, and a placement slot 2211 connected to the plug-in slot 2212 is provided on the end face of the terminal column 221 facing the plug-in slot 2212, that is, the placement slot 2211 is opened on the slot wall surrounding the plug-in slot 2212, so that the placement slot 2211 is an annular groove. The cage spring 223 is arranged in a ring shape as a whole, and the outer diameter of the cage spring 223 is adapted to the radial dimension of the placement groove 2211, so that the cage spring 223 can be arranged in the placement groove 2211, and the terminal column 221 is also fixedly provided with a limiting ring 224 at the position of the placement groove 2211. When the cage spring 223 is placed in the placement groove 2211, the limiting ring 224 can be pressed into the placement groove 2211, and one end of the limiting ring 224 is tightly pressed against the cage spring 223.

When the cable is connected to the cable connector, it is first necessary to extend from the end of the screw shell 16 away from the connection end 13 into the screw shell 16, and then connect to the cable connector. In addition, a sealing sleeve 161 is also provided inside the end of the screw shell 16 away from the connection end 13. When the cable is extended into the screw shell 16, the cable can be inserted into the sealing sleeve 161, so that the outer surface of the cable is tightly attached to the inner wall of the sealing sleeve 161, thereby increasing the sealing between the cable and the screw shell 16.

In one embodiment, please refer to FIG. 1 and FIG. 8 , a groove (not shown) is provided at one end of the plug body 11, and the plug 1 further includes a plug-in terminal 12 connected to the plug body 11, a part of the plug-in terminal 12 is located in the groove of the plug body 11, and the other end is extended out of the groove. A spacing is provided between the plug-in terminal 12 located in the plug body 11 and the plug body 11, and a ring groove 14 can be formed around it. The plug-in portion 312 of the socket 3 is also provided in a ring shape, and the size of the plug-in portion 312 is adapted to the size of the ring groove 14, so that the plug-in portion 312 can be plugged and adapted in the ring groove 14.

It should be noted that when the pin terminal 33 is plugged into the socket body 31, the end of the pin terminal 33 for plugging into the plug slot 2212 is located in the middle of the space surrounded by the plug portion 312. When the plug portion 312 is plugged into the annular groove 14, the pin terminal 33 is arranged opposite to the plug slot 2212.

It should also be noted that a sealing ring 121 is protruding from the outer wall of the plug end 12. The sealing ring 121 is preferably a plastic or silicone ring. When the plug-in portion 312 is plugged into the annular groove 14, the outer wall of the sealing ring 121 can be tightly attached to the inner wall of the plug-in portion 312 to achieve the sealing of the connection between the plug-in portion 312 and the plug 1, which can achieve a waterproof effect.

It is worth mentioning that when the plug-in portion 312 is plugged into the annular groove 14, it can be clamped in the annular groove 14 through the clamping member 15 to achieve the connection between the socket 3 and the plug 1, and the clamping member 15 has different position states. By moving in different position states, the plug-in portion 312 can be installed and disassembled.

Specifically, please refer to Figures 5 to 7 together. A movable groove 112 is opened in one direction in the plug body 11 and communicates with the annular groove 14. The movable groove 112 is opened at one end of the opening direction. The clamping member 15 is elastically arranged in the movable groove 112 along the opening path of the movable groove 112. The clamping member 15 can move in the movable groove 112 along the first direction and the second direction. The first direction and the second direction are opposite. Please refer to Figure 5. The dotted arrow in the figure indicates the first direction, and the real arrow indicates the second direction.

In the free state, the clamping member 15 is stationary in the moving groove 112, and a part of the structure of the clamping member 15 can extend into the annular groove 14 through the connection between the moving groove 112 and the annular groove 14. A protrusion 311 is also protruded on the plug-in portion 312. When the plug-in portion 312 is plugged into the annular groove 14, the structure of the clamping member 15 extending into the annular groove 14 is located on the moving path of the protrusion 311. At this time, by moving the clamping member 15 along the first direction, the structure of the clamping member 15 can be misaligned with the protrusion 311, so that the plug-in portion 312 can be smoothly plugged into the annular groove 14. After the plug-in portion 312 is inserted into the predetermined position of the annular groove 14 (the predetermined position is also the final plug-in position of the plug-in portion 312 relative to the annular groove 14 when the socket 3 is connected to the plug 1), the clamping member 15 is released. Under the action of elastic force, the clamping member 15 can be restored to its original position in a reset state along a second direction opposite to the first direction. At this time, part of the structure of the clamping member 15 is again blocked on the moving path of the protrusion 311 when the plug-in portion 312 is separated from the annular groove 14, so as to clamp the protrusion 311 in the annular groove 14, thereby realizing a fixed connection between the plug 1 and the socket 3.

More specifically, the clamping member 15 is provided with a first guiding inclined surface 152 and a giving portion 154, which are sequentially arranged along the second direction, and the structure of the giving portion 154 is preferably concave, and the protrusion 311 is provided with a second guiding inclined surface 3111. The first guiding inclined surface 152 is gradually inclined toward the plug-in end 12 in the plug-in direction of the plug-in portion 312, and the second guiding inclined surface 3111 is gradually inclined away from the plug-in portion 312 in the plug-in direction of the plug-in portion 312. In the free state, the first guide bevel 152 is located on the moving path of the second guide bevel 3111 along the plugging direction of the plug-in portion 312. During the process of the plug-in portion 312 being plugged into the annular groove 14, the first guide bevel 152 can abut against the second guide bevel 3111. Due to the setting of the two guide bevels, during the process of the plug-in portion 312 being gradually plugged into the annular groove 14, the first guide bevel 152 and the second guide bevel 3111 can fit exactly or partially fit together.

As the plug-in portion 312 continues to move, the first guide slope 152 gradually tilts toward the plug-in end 12, and the second guide slope 3111 gradually tilts away from the plug-in portion 312, and the clamping member 15 moves. In this way, the second guide slope 3111 cooperates with the first guide slope 152 to drive the clamping member 15 to move in the moving groove 112 along the first direction, and when the clamping member 15 moves, the yielding portion 154 gradually approaches the protrusion 311, so that the movement of the protrusion 311 allows the clamping member 15 to move in the first direction. During the insertion of the plug-in portion 312, the protrusion 311 can move to the yielding portion 154 through the movement of the clip 15, so that the protrusion 311 can pass through the clip 15 smoothly. After the protrusion 311 completely passes through the yielding portion 154, the clip 15 returns to its original position along the second direction under the action of the elastic force. At this time, the yielding portion 154 of the clip 15 and the protrusion 311 are misaligned. When trying to pull the plug-in portion 312 out of the annular groove 14, the protrusion 311 will be blocked by the clip 15.

Preferably, a buckle 151 and an elastic member 153 are also provided on the snap connector 15, and a slot 113 connected to the movable slot 112 is also opened along the opening direction of the movable slot 112 on the plug body 11, and the buckle 151 is located in the slot 113, and the range of movement of the buckle 151 in the slot 113 can limit the range of movement of the snap connector 15 in the movable slot 112.

The elastic member 153 is disposed in the movable groove 112. The elastic member 153 is preferably a spring. One end of the elastic member 153 can be connected to the clamping member 15. Specifically, a groove structure can be provided at the end of the clamping member 15. One end of the spring is inserted into the groove structure. The other end of the elastic member 153 can abut against the groove wall of the movable groove 112 and is located on the path of the clamping member 15 moving along the first direction. When an external force is applied to the clamping member 15 to drive the clamping member 15 to move along the first direction, the elastic member 153 can be squeezed, so that the elastic member 153 has elastic force. When the clamping member 15 is released, the elastic force of the elastic member 153 drives the clamping member 15 to return to its original position in the opposite direction.

By providing the clip 15 and the elastic member 153, the clip 15 has a tendency to return to its original position after being driven by an external force to move in the first direction, and can return to its original position when the external force is removed. In addition, by providing the first guide slope 152 and the second guide slope 3111, a driving force can be provided for the movement of the clip 15 in the first direction during the process of the plug-in portion 312 being plugged into the annular groove 14, so as to drive the clip 15 to move in the first direction to make way for the protrusion 311. After the plug-in portion 312 is plugged into a predetermined position (which can also be regarded as a locked position), the clip 15 returns to its original position under the action of the elastic force to achieve locking.

When unlocking, the socket can be pulled out smoothly by simply pressing the clamping member 15 to move along the first direction so that the yielding portion 154 faces the protrusion 311 .

This snap-fit structure requires fewer structures and can more easily achieve locking and unlocking between the socket and the plug. Locking and unlocking are achieved through the cooperation of the snap-fit member 15 and the protrusion 311, and the required plugging and unplugging force is also smaller, which can increase the plugging and unplugging life.

It should be noted that the plug-in portion 312 is provided with a plurality of protrusions 311 at equal intervals around its peripheral wall, the second guide slope 3111 is provided on the end face of the protrusion 311 facing away from the plug-in portion 312, and the end face of the plug body 11 facing the plug end 12 is provided with a plurality of guide grooves 111 at equal intervals around the peripheral wall for plugging and matching with the protrusions 311, the guide grooves 111 are provided along the plugging direction of the plug-in portion 312, and one of the guide grooves 111 can be connected to the annular groove 14 and the movable groove 112 at the same time. It is worth mentioning that the plurality of protrusions 311 are completely consistent, and the plurality of guide grooves 111 are completely consistent.

By providing a plurality of protrusions 311 and a plurality of guide grooves 111 corresponding to the protrusions 311, the cooperation between the protrusions 311 and the guide grooves 111 plays a role of limiting, so that the plug-in portion 312 can be accurately plugged into the annular groove 14, and when the protrusion 311 moves along one of the guide grooves 111, it can contact the clamping member 15. In addition, through this arrangement of circumferential equal spacing, it is also convenient to plug and unplug the socket at any angle of 360° on the plug 1.

In one embodiment, referring to FIG. 1 and FIG. 9 to FIG. 11 , the socket 3 further includes a sealing gasket 32 connected to the socket body 31 and a limiting ring 321 for auxiliary limiting.

An insulating cap 331 is provided at one end of the pin terminal 33. The provision of the insulating cap 331 can prevent accidental electric shock to fingers. The other end of the pin terminal 33 is buckled into the socket body 31. Specifically, a plurality of claws 313 are provided in the inner ring of the socket body 31. The claws 313 are elastic, and a plug-in space is formed between the claws 313. A fixed bone position 333 is provided on the peripheral wall of the pin terminal 33. The radial dimension of the fixed bone position 333 is larger than the dimension of the plug-in space surrounded by the claws 313. When the pin terminal 33 is plugged into the plug-in space and continues to be plugged into the fixed bone position 333 and moves to the plug-in space along the plug-in direction, the fixed bone position 333 can force the claw 313 to undergo elastic deformation to expand the dimension of the plug-in space, so that the fixed bone position 333 passes through the plug-in space, and the claw 313 returns to its original position by elastic deformation, thereby realizing the plug-in of the pin terminal 33.

It should be noted that a planar limiting end face 332 is relatively arranged on the outer wall of the pin terminal 33, and a plane that can fit with the limiting end face 332 is arranged at a position corresponding to the limiting end face 332 in the socket body 31. When the pin terminal 33 is plugged into a predetermined position, the limiting end face 332 on the pin terminal 33 can fit on the plane inside the socket body 31 to limit the rotation of the pin terminal 33 relative to the socket body 31.
