[0022] Example 1 like Figure 1 , 2As shown, this embodiment provides a connector socket 10; a threaded head 102 is provided at the socket interface 101 of the connector socket 10, and an external thread 104 is provided on the outer cylindrical surface of the threaded head 102, and the tail end of the threaded head 102 (with the plug-in end of the connector socket 10 as the front end) is axially connected with a slot section 103, and an outer wall slot 105 is provided on the outer cylindrical surface of the slot section 103 along the plug-in direction of the head seat, and an avoidance groove 106 is formed on the outer cylindrical surface of the threaded head 102, and the avoidance groove 106 is provided along the plug-in direction, and corresponds to the opening of the outer wall slot 105 and has the same number, and the function of the avoidance groove 106 is: when the quick-lock connector plug 20 is plugged and connected with the connector socket 10, the quick-lock connector plug 20 will not be hindered by the external thread 104.

[0023] The connector socket 10 of this embodiment is compatible with the connection Figure 1 The threaded connector plug 30 shown is also compatible with Figure 2 The quick-lock connector plug 20 shown in the figure. The threaded head 102 is used to achieve a mating connection with the threaded connector plug 30, and the slot section 103 is used to achieve a mating connection with the quick-lock connector plug 20. In this embodiment, the head seat can be plugged in and locked by directly pushing the tail of the quick-lock connector plug 20. One solution can be compatible with two connector plugs.

[0024] In this embodiment, the outer wall slot 105 can adopt the following structure: it includes a slide slot 1051 and a locking slot 1052 arranged at the tail of the slide slot 1051, and a sloped protrusion 1053 is arranged on one side between the slide slot 1051 and the locking slot 1052. The sloped protrusion 1053 has an insertion slope 1053-1 located in the slide slot 1051 and a stop surface 1053-2 located in the locking slot 1052. The insertion slope 1053-1 forms a certain angle with the insertion direction. The insertion slope 1053-1 is mainly used to guide the adapter block 22 when the head seat is inserted. The stop surface 1053-1 is mainly set to stop the adapter block 22 when the head seat is locked. Preferably, the stop surface 1053-2 faces the locking slot 203 and is arranged along the rotation direction of the hood 2.

[0025] Example 2 like Figure 3-11As shown, this embodiment provides a quick-lock connector plug, including a plug housing Ⅰ1 and a hood 2 arranged at the plug housing Ⅰ1 plug end 11, the hood 2 can rotate relative to the plug housing Ⅰ1, and a receiving cavity 14 for installing an elastic member 3 is arranged in the gap between the hood 2 and the plug housing Ⅰ1, one end of the elastic member 3 contacts the plug housing Ⅰ1, and the other end contacts the hood 2, the hood 2 can squeeze the elastic member 3, so that the hood 2 rotates relative to the plug housing Ⅰ1 along a first rotation direction, and at the same time, the elastic member 3 is squeezed to generate a rebound force for realizing the rotation and reset of the hood 2 along a second rotation direction (opposite to the first rotation direction), so the hood 2 can be quickly reset under the action of the rebound force of the elastic member 3. This solution realizes the quick plug-in locking or quick unlocking of the quick-lock connector plug 20 and the adapter connector socket 10 through the cooperation of the plug housing Ⅰ1, the hood 2 and the elastic member 3, improves the convenience of plug-in locking and unlocking, saves operation time, and reduces the difficulty of locking and unlocking separation during the plug-in process.

[0026] In this embodiment, an inner cavity 15 for accommodating the plug inner core 7 and the insulator 8 is formed inside the plug housing Ⅰ1, and a hole cavity for accommodating the pin of the plug inner core 7 is formed in the insulator 8 along the axial direction. A plug tail seat 6 is provided at the tail end of the plug housing Ⅰ1, and the plug tail seat 6 can be connected to the tail end of the plug housing Ⅰ1 by means of threading, snap-fitting or bonding; a groove-shaped space 13 is arranged circumferentially around the outer wall of the plug housing Ⅰ1 close to the plug-in end 11, and an opening 131 for the key 21 to be assembled and entered is formed at the head end of the groove-shaped space 13, and the opening 131 corresponds to one end of the elastic member 3, and a stop plate 132 is provided at the tail end of the groove-shaped space 13 (with the opening 131 of the groove-shaped space 13 as the front end and the stop plate 132 of the groove-shaped space 13 as the tail end), the tail end of the elastic member 3 can contact one side of the key 21, and the head end of the elastic member 3 can abut against the tail end stop plate 132 of the adjacent groove-shaped space 13, the elastic member 3 can adopt an ordinary compression spring, and in other embodiments of the present scheme, other types of elastic members can also be used, and the elastic member 3 can provide a circumferential force for the rotation of the hood 2.

[0027] In this embodiment, the function of the groove-shaped space 13 is to accommodate the key 21 in the hood 2. The key 21 can enter the groove-shaped space 13 through the opening 131 of the groove-shaped space 13 and can move in the groove-shaped space 13 along the rotation direction of the hood 2, and one end of the key 21 contacts one end of the elastic member 3. Preferably, when the elastic member 3 is stretched, the end of the elastic member 3 can enter the groove-shaped space 13 through the opening 131 and abut against one end of the key 21. The groove-shaped space 13 is surrounded by the arc-shaped protrusions 12 located on the opposite sides, the circumferential steps 16 of the outer wall of the plug housing Ⅰ1, and the stopper plate 132 located at the rear. The width of the groove-shaped space 13 gradually narrows from the opening 131 to the rear end. The purpose of such design is to ensure that the opening 131 has a large opening angle to facilitate the assembly of the key 21, while avoiding the formation of obstacles to the expansion and contraction of the elastic member 3, which is conducive to the end of the elastic member 3 smoothly entering the groove-shaped space 13 and contacting and fitting with one end of the key 21.

[0028] In the present invention, the hood 2 adopts the following structure: the hood 2 is an annular sleeve, and the hood 2 has a cavity 27, which is arranged along its axial direction. The function of the cavity 27 is to achieve the plugging and locking of the connector plug 20 and the adapter connector socket 10 therein, and a key 21 is arranged around the inner wall of the cavity 27 near the rear end of the hood 2 along the circumferential direction. The function of the key 21 is that the key 21 contacts one end of the elastic member 3, and the hood 2 is matched with the elastic member 3 through the key 21. Blocks 22 are evenly distributed on the inner wall of the cavity 27 near the front end of the hood 2.

[0029] In the present solution, in order to ensure the axial assembly effect between the connecting hood 2 and the plug housing 1, an annular groove 23 is circumferentially arranged on the inner wall of the cavity 27 of the connecting hood 2, and the annular groove 23 is used to install a retaining ring 4, and the retaining ring 4 is fixedly mounted in the annular groove 23 by its own elastic force. Preferably, the retaining ring 4 can adopt the following structure: the retaining ring 4 is a ring with a disconnection, and the two ends of the retaining ring 4 are pressed inwardly so that the retaining ring 4 can be easily inserted into the annular groove 23, and then reset and fixed in the annular groove 23 by its own elastic force. In other embodiments, the retaining ring 4 can also be mounted in the annular groove 23 by other types of assembly methods. The function of the retaining ring 4 is to effectively ensure the axial position of the hood 2 after installation. When the hood 2 is installed, its key 21 is inserted into the inside of the groove space 13 through the opening 131. At the same time, due to the elastic force of the elastic member 3, the key 21 is prevented from escaping outward from the opening 131 of the groove space 13. In addition, since the key 21 is assembled in the groove space 13, the key 21 will form an axial fit with the first side surface of the arc-shaped protrusion 12, thereby forming a limit stop for the hood 2 relative to the plug housing 1 along the first axial direction (moving toward the plugging direction). The retaining ring 4 and the second side surface of the arc-shaped protrusion 12 A fit is formed, thereby limiting the movement of the connecting cap 2 relative to the plug housing 1 along the second axial direction (towards the rear end of the plug housing 1). In this solution, the first side surface of the arc-shaped protrusion 12 is the side surface facing the rear end direction of the plug housing Ⅰ1, and the second side surface of the arc-shaped protrusion 12 is the side surface facing the plug-in end 11 of the plug housing Ⅰ1. Preferably, a gasket 5 is also provided between the retaining ring 4 and the arc-shaped protrusion 12. The gasket 5 is used to compensate for the assembly clearance margin between the retaining ring 4 and the arc-shaped protrusion 12, and at the same time reduce the wear of the contact surfaces between the retaining ring 4 and the arc-shaped protrusion 12.

[0030] In a typical embodiment of the present invention, the plug end of the connector plug 20 is provided with more than two groove-shaped spaces 13. Figure 4 , 9 , 11, the structure is introduced by taking two groove-shaped spaces 13 as an example. The two groove-shaped spaces 13 are groove-shaped space I 133 and groove-shaped space II 134 respectively. The two groove-shaped spaces 13 are evenly distributed on the plug-in end 11 of the plug housing 1, and the openings 131 of the two groove-shaped spaces 13 are arranged along the same rotation direction of the hood 2. A key 21 is arranged at the tail end of the inner wall of the cavity 27 of the hood 2. In order to cooperate with the groove-shaped space I 133 and the groove-shaped space II 134, the key 21 includes two groups of key blocks, one of which is a key I 211 arranged on the circumferential direction of the inner wall of the cavity 27 as shown in the figure. One end of the key I 211 can contact the tail end of the spring I 31, and the head end of the spring I 31 contacts the stop plate 132 at the tail end of the adjacent groove-shaped space 13. The other group of key blocks includes as shown in the figure. Fig.11The key II 212 and key III 213 shown in the figure have the same combined function as the key I 211. The difference is that a gap is formed between the key II 212 and the key III 213. The purpose of setting the gap here is to be used for demoulding of the protruding design structure of the inner wall of the hood 2, wherein the key I 211 is inserted into the opening 131 of the groove-shaped space I 133 and can be movably arranged in the groove-shaped space I 133, the key II 212 and the key III 213 are inserted into the opening 131 of the groove-shaped space II 134 and can be movably arranged in the groove-shaped space II 134, the key II 212 is located in the groove-shaped space 13 after assembly and can contact the stop plate 132, the key III 213 contacts the tail end of the spring II 32, and the head end of the spring II 32 contacts the stop plate 132 (the tail end of the groove-shaped space 13) of the adjacent groove-shaped space 13.

[0031] In the present invention, vertical anti-slip stripes 28 are arranged on the outer cylindrical surface of the hood 2 in the axial direction, in order to increase the friction with the outer surface of the hood 2 when the operator twists the hood 2. At the same time, a plug-in direction indicating arrow 25 and a twisting direction indicating arrow 26 are arranged on the outer cylindrical surface of the hood 2.

[0032] As shown in the figure, in this scheme, an installation gap for the key 21 of the hood 2 is formed between the two groove-shaped spaces 13. When the hood 2 is assembled with the plug housing Ⅰ1, the key 21 of the hood 2 will be inserted axially from the installation gap, and then the hood 2 is rotated so that the key 21 further enters the groove-shaped space 13 from the opening 131, and the elastic member 3 is installed so that one end of the elastic member 3 contacts the key 21, and the other end of the elastic member 3 contacts the tail end of the adjacent groove-shaped space 13. At this time, the key 21, the stop plate 132 of the groove-shaped space 13 and the circumferential step 16 enclose the installation gap to form a accommodating cavity 14 for installing the elastic member 3, and the elastic member 3 can shrink or stretch in the accommodating cavity 14 with the squeezing action of the key 21.

[0033] Example 3 like Figure 2As shown, the present embodiment provides a connector, comprising a connector socket 10 of embodiment 1 and a quick-lock connector plug 20 of embodiment 2, wherein the connector socket 10 and the quick-lock connector plug 20 realize quick-lock plug-in matching of a head seat, through the concave-convex matching structure formed by the inclined protrusion 1053 of the connector socket 10 and the card block 22 on the quick-lock connector plug 20, and the automatic rebound structure formed by the key 21 of the hood 2 and the elastic member 3, the hood 2 rotates and realizes automatic locking through the above-mentioned automatic rebound structure by utilizing the concave-convex matching structure, and the specific locking and unlocking process is as follows: when the head seat is plugged in, the tail of the connector plug 20 is pushed in the axial direction, and the card block 22 of the hood 2 will follow the slide groove 1051 into the outer wall card groove 13, during the sliding process, the elastic member 3 is compressed, and the elastic force of the elastic member 3 increases, and after passing over the inclined protrusion 1053, the card block 22 will automatically slide into the locking groove 1052, at which time the elastic member 3 automatically extends back to its position, and the locking process of the head seat is completed. When the head seat is unlocked, the hood 2 is manually rotated in the opposite direction, the block 22 is released from the locking groove 1052, and after passing over the inclined protrusion 1053, the quick-lock connector plug 20 is pulled out axially to achieve rapid separation of the head seat, and the head seat unlocking process is completed.

[0034] In order to achieve the coordination between the outer wall slot 105 and the block 22 in the inner cavity of the hood 2, when the head seat is plugged in, after the block 22 contacts the plug-in inclined surface 1053-1, the plug-in inclined surface 1053-1 will guide the block 22 to one side along the slide groove 1051 along the torsion direction, thereby driving the rotation of the hood 2. At this time, the key 21 at the tail end of the hood 2 also gradually squeezes the elastic member 3 synchronously. When the block 22 reaches the most protruding position of the inclined protrusion 1053, the elastic member 3 accumulates a certain reset force. As the block 22 passes over the inclined protrusion 1053, the elastic member 3 uses the accumulated reset force to push the hood 2 to rotate in the locking direction, so that the block 22 smoothly enters and is locked in the locking slot 1052. At the same time, the block 22 and the stop surface 1053-2 form a stop effect. When the head seat is unlocked, the operator twists the hood 2 in the unlocking direction, and the block 22 escapes from the lock groove 1052. At the same time, the key 21 squeezes the elastic member 3. When the block 22 passes over the inclined protrusion 1053, the quick-lock connector plug 20 can be pulled out along the axial direction in the separation direction.

[0036] In this embodiment, the threaded connector plug 30 includes a plug housing II 31 and a nut 32 arranged at the head end of the plug housing II 31. The nut 32 can rotate relative to the plug housing II 31, and a stopper structure is arranged axially between the two to prevent the two from being relatively separated in the axial direction. An internal thread that matches the external thread 104 of the thread head 102 is arranged on the inner wall of the cavity of the nut 32. When the threaded connector plug 30 is plugged into the connector socket 10, the threaded connector plug 30 and the connector socket 10 can be locked by rotating the nut 2 in the locking direction. When the head seat needs to be unlocked, the threaded connector plug 30 and the connector socket 10 can be unlocked by rotating the nut 2 in the unlocking direction.

During the sliding process, the elastic member 3 will be compressed and the elastic force will increase. When the block 22 slides into the locking groove 1052, the head seat locking process is completed. When unlocking, manually twist the hood 2 in the opposite direction. When the block 22 in the hood 2 withdraws from the outer wall groove 105 of the connector socket 10, a separation force is applied axially to pull out the quick-lock connector plug 20 axially. The block 22 withdraws from the outer wall groove 105 and comes out of the avoidance groove 106, and the unlocking process is completed.

[0040] In the present solution, the quick-lock connector plug 20 is provided with a hood 2 at the plug-in end of the plug housing Ⅰ1, and the structures of the plug housing Ⅰ1 and the hood 2 are improved. An elastic member 3 is provided in the gap between the plug housing Ⅰ1 and the hood 2. The hood 2 can compress the elastic member 3 and accumulate the reset force when the head seat is locked, and under the action of the elastic member 3, the hood 2 is pushed to achieve the head seat locking connection. When the head seat is unlocked, the elastic member 3 is compressed by the hood 2 and the quick-lock connector plug 20 is pulled out, and the elastic member 3 will further push the hood 2 to achieve rotational reset. Through the buckle structure composed of the inclined protrusion 1053 in the outer wall slot 103 of the socket interface 101, the block 22 in the hood 2, and the automatic rebound structure composed of the elastic member 3 and the key 21, the head seat can be automatically locked when it is axially inserted through the cooperation of the buckle structure and the automatic rebound structure. When unlocking, by rotating the hood 2, the block 22 can be rotated out of the outer wall slot 105 and axially pulled out, thereby completing rapid separation.
