At the same time, the threaded connection method requires the user to twist many turns to connect and tighten, which is not convenient and quick to use.

[0052] The overall idea of ​​the technical solution provided by the present invention is as follows:

[0053] The quick-connect high-reliability sealed connector connection structure includes: a socket 100, a receiving cavity 110 is provided inside the socket 100, and a fastener 120 is provided on the inner wall of the socket 100; a plug 300, the plug 300 is used to be inserted into the receiving cavity 110; a locking groove 310, the locking groove 310 is provided on the outer wall of the plug 300, the locking groove 310 includes a first groove body 311 arranged horizontally, the position of the first groove body 311 matches the position of the fastener 120 when the plug 300 is inserted into the receiving cavity 110, and when the plug 300 is rotated, the fastener 120 enters the first groove body 311 to limit the fastener 120; a first waterproof member 400, the first waterproof member 400 is provided with at least one, and the first waterproof member 400 is used to be arranged between the outer wall of the plug 300 and the inner wall of the socket 100 when the plug 300 is inserted into the socket 100. When in use, the plug 300 is inserted into the receiving cavity 110 of the socket 100, and then the plug 300 is rotated. 00, so that the fastener 120 on the inner wall of the socket 100 enters the locking groove 310 on the outer wall of the plug 300 and is fastened, thereby completing the connection between the plug 300 and the socket 100. Because the length of the locking groove 310 is fixed, the fastener 120 will be fastened when it enters a certain position of the locking groove 310, thereby avoiding the problem of inaccurate connection between the socket 100 and the plug 300 in the prior art. At the same time, this connection method only needs to rotate a small angle to complete the connection, and does not require many turns. It is convenient and quick to use.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0055] Please refer to Figures 1 to 19 An embodiment of the present invention provides a quick-connect high-reliability sealed connector connection structure, which includes: a socket 100, a plug 300 and a first waterproof component 400.

[0056] The socket 100 is provided with a receiving cavity 110, and the inner wall of the socket 100 is provided with a fastener 120. The socket 100 is a fixed end connector, which is generally fixed at a specified position. The socket 100 may be provided with a fixing seat and a fixing through hole for fixed connection with an external device, wherein Figure 5 As shown, the fixing seat can be rectangular or refer to Figure 14 The fixing seat is square, and a sealing rubber ring can be provided at the bottom of the fixing seat for sealing connection with external equipment.

[0057] The third waterproof component 200 is arranged at the bottom of the accommodating cavity 110, wherein the third waterproof component 200 can adopt a sealing rubber ring, such as a rubber sealing ring. The sealing rubber ring has a certain elasticity. When the plug 300 is inserted into the accommodating cavity 110, the sealing rubber ring can be deformed, so that the sealing rubber ring is tightly connected to the plug 300, thereby playing a waterproof role.

[0058] The locking groove 310 is provided on the outer wall of the plug 300. The locking groove 310 includes a first groove body 311 arranged transversely. The position of the first groove body 311 matches the position of the fastener 120 when the plug 300 is pressed against the third waterproof member 200. When the plug 300 is rotated, the fastener 120 enters the first groove body 311 so that the fastener 120 is restrained. Figure 16 The locking groove 310 may further include a guide groove 312 connected to the first groove body 311. The first groove body 311 may be arranged perpendicular to the guide groove 312. When the plug 300 is inserted into the accommodating cavity 110, the fastener 120 is inserted into the guide groove 312. When the fastener 120 moves along the guide groove 312 to the position of the first groove body 311, the fastener 120 is limited by the end of the first groove body 311. At this time, the plug 300 is rotated and the fastener 120 enters the first groove body 311. The first groove body 311 guides and limits the fastener 120. Optionally, the number of the locking grooves 310 and the fastener 120 are both four.

[0059] The first waterproof member 400 is provided with at least one Figure 16 As shown, the first waterproof member 400 may be provided with one or more Figure 20 and Figure 21As shown, the first waterproof member 400 can be provided with two or even more. The first waterproof member 400 is used to be provided between the outer wall of the plug 300 and the inner wall of the socket 100 when the plug 300 is inserted into the socket 100. More specifically, the first waterproof member 400 needs to be provided around the outer wall of the plug 300 and provided above the locking groove 310. Of course, please refer to Figure 7 The first waterproof component 400 can also be arranged around the position above the fastener 120 on the inner wall of the socket 100. The first waterproof component 400 is a sealing rubber ring. The position of the first waterproof component 400 is that when the plug 300 is inserted into the accommodating cavity 110 and fixed, it is located between the plug 300 and the socket 100 inside the accommodating cavity 110. The first waterproof component 400 is sandwiched between the plug 300 and the socket 100 and deforms, that is, the first waterproof component 400 is tightly connected to the plug 300 and the socket 100 respectively, thereby achieving a waterproof effect.

[0060] More specifically, the locking groove 310 is provided on the outer wall of the plug 300 because in this way the first waterproof component 400 can be provided above the locking groove 310, thereby completing the side waterproofing between the plug 300 and the socket 100. If the locking groove 310 is provided on the inner wall of the socket 100, and the fastener 120 is provided on the outer wall of the plug 300, there must be a guide groove 312 between the plug 300 and the socket 100 when the two are connected. In this way, only a waterproof component can be provided between the top ends of the plug 300 and the socket 100, such as the position of the third waterproof component 200, which cannot achieve the effect of side waterproofing.

[0061] See also Figures 1 to 4 、 Figure 6 and Figure 17 A quick-connect high-reliability sealed connector connection structure also includes: an outer ring 500, a first hollow portion 510 is provided in the outer ring 500, and the plug 300 is provided in the first hollow portion 510, wherein a first snap-fit ​​connection mechanism is provided between the socket 100 and the outer ring 500, and a second snap-fit ​​connection mechanism is provided between the plug 300 and the outer ring 500. Specifically, the outer ring 500 is moved downward, and the outer ring 500 and the socket 100 are matched and connected through the first snap-fit ​​connection mechanism. At the same time, the outer ring 500 0 and the plug 300 are disengaged, the outer ring 500 is locked and cannot drive the plug 300 to rotate, thereby preventing the plug 300 from being accidentally touched and rotated. When the plug 300 needs to be rotated, the outer ring 500 is pulled upward, and the outer ring 500 and the plug 300 are matched and connected through the second fastening connection mechanism. At the same time, the first fastening connection mechanism between the outer ring 500 and the socket 100 is disengaged, so that the outer ring 500 can drive the plug 300 to rotate.

[0062] In one embodiment, the first snap-fit ​​connection mechanism includes a third protrusion 520 and a first groove 130 that are matched, and the second snap-fit ​​connection mechanism includes a fourth protrusion 320 and a second groove 530 that are matched.

[0063] Among them, you can refer to Figures 5 to 16 A first groove portion 130 is provided on the top of the socket 100, and a third protrusion 520 is provided inside the outer ring member 500. The third protrusion 520 and the first groove portion 130 are matched. A fourth protrusion 320 is provided on the upper part of the plug 300, and a second groove portion 530 is provided on the inner wall of the outer ring member 500. The fourth protrusion 320 and the second groove portion 530 are matched. Specifically, in actual use, the outer ring member 500 is sleeved on the outside of the plug 300, and the outer ring member 500 can slide and rotate relative to the plug 300.

[0064] First, the fourth protrusion 320 of the plug 300 is inserted into the second groove 530 of the outer ring 500 and is stuck. At this time, the outer ring 500 rotates to drive the plug 300 to rotate, and the plug 300 is inserted into the accommodating cavity 110. The outer ring 500 rotates to drive the plug 300 to rotate, and the fastener 120 enters the locking groove 310 and is limited, so that the plug 300 is fixed in the accommodating cavity 110. The position of the third protrusion 520 of the outer ring 500 should correspond to the position of the first groove 130 at the top of the socket 100. When the outer ring 500 moves downward, the third protrusion 520 of the outer ring 500 enters the first groove 130 of the socket 100 and is restrained. At the same time, the second groove 530 of the outer ring 500 disengages from the fourth protrusion 320 of the plug 300. The outer ring 500 is locked and cannot drive the plug 300 to rotate, thereby preventing the plug 300 from being accidentally touched and rotated. At the same time, when the third protrusion 520 of the outer ring 500 is inserted into the first groove 130, the outer ring 500 covers the plug 300, thereby providing a certain degree of dust and water protection.

[0065] When the plug 300 needs to be rotated, the outer ring member 500 is pulled upward, and the second groove portion 530 of the outer ring member 500 is connected to the fourth protrusion portion 320 of the plug. At the same time, the third protrusion portion 520 of the outer ring member 500 is separated from the first groove portion 130 on the top of the socket 100, so that the outer ring member 500 can drive the plug 300 to rotate, so that the fastener 120 leaves the locking groove 310, and the plug 300 can be taken out of the accommodating cavity 110. After ensuring that the plug 300 is connected and fixed to the socket 100, it can be locked. The locking and unlocking actions are convenient and quick. At the same time, the outer ring member 500 also provides dust and water resistance, making the overall working stability of the product stronger.

[0066] It is understandable that the first groove portion 130 can be arranged in various ways, such as Figure 8 and Figure 15 As shown, the socket 100 may be provided with a sinking structure on the top, and part of the first groove portion 130 may be provided in the sinking structure. Figure 15 In the embodiment, the first groove portion 130 is completely disposed in the sink, so that the top of the socket 100 is a flat end, or as shown in FIG. Figure 9 As mentioned above, the first groove portion 130 can be set to be fully open, or as Figure 12 As shown, the first groove portion 130 may be provided at the inner side of the top of the socket 100, as shown in FIG. Figure 13 There is a certain gap between the third protrusion 520 provided on the outer ring member 500 and the inner side wall of the outer ring member 500 .

[0067] It can be understood that, based on the above, the positions of the first groove portion 130 and the third protrusion portion 520 can be interchanged, and the positions of the second groove portion 530 and the fourth protrusion portion 320 can also be interchanged. Figure 10 and Figure 11 The first groove portion 130 can be set inside the outer ring member 500 and the third protrusion portion 520 can be set on the top of the socket 100, the second groove portion 530 can be set on the upper part of the plug 300 and the fourth protrusion portion 320 can be set on the inner wall of the outer ring member 500. The technical effect achieved after the positions are interchanged is the same.

[0068] See also Figure 6 The outer wall of the outer ring 500 is provided with an anti-slip portion 540, and the anti-slip portion 540 can be made of rubber material. At the same time, the outer surface of the anti-slip portion 540 can be provided with a plurality of grooves to increase the friction when the user contacts the outer surface of the anti-slip portion 540, thereby playing an anti-slip role. By adding the anti-slip portion 540, it is more convenient for the user to rotate and move the outer ring 500.

[0069] See also Figure 3 and Figure 6The outer ring 500 has a first protrusion 550 on its inner wall, and the plug 300 has a second protrusion 330 on its outer wall. A first elastic member 900 is provided between the first protrusion 550 and the second protrusion 330. The first elastic member 900 provides elastic force between the outer ring 500 and the plug 300, so that the outer ring 500 and the plug 300 can return to their original position after relative movement. Specifically, the first elastic member 900 provides elastic force to keep the outer ring 500 and the plug 300 from moving relative to each other. When the plug 300 is fixed by the fastener 120, the third protrusion 520 of the outer ring member 500 is pressed into the first groove 130 by the elastic force of the first elastic member 900. A certain amount of force is required to overcome the elastic force of the first elastic member 900 in order to pull out the outer ring member 500, thereby preventing the third protrusion 520 of the outer ring member 500 from easily separating from the first groove 130. At the same time, the first elastic member 900 does not affect the relative rotational movement of the outer ring member 500 and the plug 300, thereby enhancing product stability.

[0070] Among them, the first protrusion 550 and the second protrusion 330 can be structures integrally formed on the outer ring member 500 and the plug 300, or they can be protruding structures such as retaining springs and screws provided on the outer ring member 500 and the plug 300, which are not limited here.

[0071] Furthermore, an anti-retraction mechanism is provided between the outer ring member 500 and the plug 300. Specifically, the anti-retraction mechanism may be a boss snap-fit ​​connection structure.

[0072] In one embodiment, see Figure 6 and Figure 16 The anti-retraction mechanism includes a first latch 560 and a second latch 340. The first latch 560 is provided on the inner wall of the outer ring 500, and the second latch 340 is provided on the outer wall of the plug 300. The first latch 560 and the second latch 340 are both provided with a guide bevel for guiding the fastening direction. The first latch 560 and the second latch 340 are both provided with a fastening surface for fastening. During actual installation, the plug 300 is inserted from the top of the outer ring 500 into the first hollow portion 510 of the outer ring 500. At this time, the guide bevels of the first latch 560 and the second latch 340 are The surfaces are relative to each other, and under the action of the guiding inclined surface, the second latch 340 moves downward through the first latch 560 and reaches below the first latch 560. At this time, the fastening surfaces of the first latch 560 and the second latch 340 are relative, and the second latch 340 can no longer retreat to the top of the first latch 560, thereby installing the plug 300 into the first hollow portion 510 to prevent the plug 300 from retreating. More specifically, the first latch 560 and / or the second latch 340 should be made of an elastic material, such as plastic, and the fastening surface can be set to a horizontal plane.

[0073] It is understandable that the anti-retraction mechanism can also be composed of a retaining spring, a metal spring and a machine screw, among which the retaining spring, the metal spring and the machine screw are all existing technologies and will not be described in detail here.

[0074] See also Figure 3 、 Figure 4 and Figure 19 A clamping piece 600 is provided at the tail of the plug 300, and a second hollow portion 610 is provided inside the clamping piece 600. The second hollow portion 610 is communicated with the accommodating cavity 110. A plurality of second elastic members 620 are provided at one end of the clamping piece 600 away from the tail of the plug 300. Nuts 700 are sleeved on the outside of the plurality of second elastic members 620. A third hollow portion 710 is provided inside the nut 700. The third hollow portion 710 is a narrow upper and wide lower structure. The nut 700 is threadedly connected to the tail of the plug 300. The clamping member 600 is mainly used to clamp the circuit inserted into the plug 300. Specifically, the nut 700 is threadedly connected to the tail of the plug 300, so that the rotating nut 700 can continuously approach and move away from the multiple second elastic members 620. When the nut 700 approaches the multiple second elastic members 620, the third hollow portion 710 of the nut 700 gradually narrows, thereby narrowing the multiple second elastic members 620, and the multiple second elastic members 620 clamp the circuit. When the nut 700 moves away from the multiple second elastic members 620, the inner third hollow portion 710 of the nut 700 changes from narrow to wide, thereby relaxing the multiple second elastic members 620, thereby loosening the circuit.

[0075] See also Figure 19 , several second elastic members 620 are arranged at intervals and form an annular structure. The cross-section of the second elastic member 620 is a quadrilateral structure that widens from narrow to wide along the center of the annular structure to the circumference. At the same time, the relative surfaces of two adjacent second elastic members 620 are parallel to each other. When tightened by the nut 700, the several second elastic members 620 are close to each other, so that the tops of the several second elastic members 620 are close to each other to form a circle, so that the tops of the several second elastic members 620 are tightly attached to the cable, further preventing water and dust from entering.

[0076] More preferably, a second waterproof member 360 is provided between the clamping member 600 and the plug 300 . The second waterproof member 360 is a waterproof rubber ring, which prevents water from entering between the clamping member 600 and the plug 300 .

[0077] Of course, if the clamping member 600 is not used, Figure 22 and Figure 23 As shown, the cable can also be fixed to the rear end of the connector by a coating process, wherein the coating method can include a coating method for the plug structure outlet or the socket structure outlet. Specifically, Figure 22 It is the rubber coating method for the outlet wires of the plug structure. Figure 23 and Figure 24It is a rubber encapsulation method for the outlet wires of the socket structure.

[0078] See also Figure 3 The outer wall of the plug 300 is provided with a stepped end surface, and a fourth waterproof component 800 is provided between the top surface of the socket 100 and the stepped end surface. The fourth waterproof component 800 can be arranged around the outer wall of the plug 300 and above the first waterproof component 400, or it can be arranged above the fastener 120 on the inner wall of the socket 100. The fourth waterproof component 800, the third waterproof component 200 and the first waterproof component 400 form multiple waterproofing, and the waterproof effect is better.

[0079] See also Figure 17 and Figure 18 A first electrode terminal 140 is provided in the socket 100, and a second electrode terminal 350 is provided in the plug 300. The first electrode terminal 140 is used to electrically connect to the second electrode terminal 350 after the fastener 120 is limited in the first slot 311. Specifically, the first electrode terminal 140 and the second electrode terminal 350 match each other after the plug 300 and the socket 100 are rotated and fixed. After the plug 300 and the socket 100 are rotated and fixed, the first electrode terminal 140 and the second electrode terminal 350 abut against each other, thereby achieving an electrical connection effect after the plug 300 and the socket 100 are rotated and connected.

[0080] In one embodiment, see Figure 16 The locking groove 310 further includes a guide groove 312 communicating with the first groove body 311. A circumferential anti-mute structure is provided between the fastener 120 and the guide groove 312, so that the terminals of the plug 300 and the socket 100 can be aligned when mated, making it more convenient to use. More specifically, there is one fastener 120; or, there are multiple fasteners 120, at least two of which have different widths. The width of the guide groove 312 corresponds to the width of the fastener 120. In other words, the horizontal position of the socket and the plug is limited, and anti-mute is performed to ensure stable contact between the plug terminals and the socket terminals. Of course, in addition to achieving the anti-mute effect through different widths, different bevel angles can also be selected to achieve this effect. For example, the side walls of at least two fasteners 120 have different inclination angles, which can also achieve the above effect.

[0081] In summary, the above one or more technical solutions in the embodiments of the present application have at least one or more of the following technical effects:

[0082] In an embodiment of the present invention, a quick-connect high-reliability sealed connector connection structure is provided. The quick-connect high-reliability sealed connector connection structure includes: a socket 100, a plug 300 and a first waterproof member 400. When in use, the plug 300 is inserted into the accommodating cavity 110 of the socket 100, and then the plug 300 is rotated so that the fastener 120 on the inner wall of the socket 100 enters the locking groove 310 on the outer wall of the plug 300 and is fastened, thereby completing the connection between the plug 300 and the socket 100. Because the length of the locking groove 310 is fixed, the fastener 120 will be fastened when it enters a certain position of the locking groove 310, thereby avoiding the connection between the socket 100 and the plug 300 in the prior art. The problem of inaccurate connection is solved. At the same time, this connection method only needs to rotate a small angle to complete the connection, and does not require many turns. It is convenient and quick to use. After the plug 300 is inserted into the accommodating cavity 110 of the socket 100, the first waterproof part 400 is arranged between the plug 300 and the side wall of the socket 100. The waterproof part arranged on the side between the socket 100 and the plug 300 is better and more stable than the waterproof part arranged between the top surface of the socket 100 and the plug 300. The whole product achieves the effect of quick connection and high-reliability sealing. Of course, in addition to being used in electrical connectors, this product can also be applied to any fluid pipeline connector to achieve the effect of sealing and quick connection.
