DETAILED DESCRIPTION

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0047] In describing the present invention, it should be noted that the terms used, such as "first" and "second," are intended solely for distinction and do not indicate or imply a distinction in importance or order. Terms such as "inner" and "outer" refer to the inside and outside of specific contours. The use of these terms is intended solely to facilitate a clear and simple description of the technical solutions of the present invention and should not be construed as limiting the present invention.

[0048] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0049] like Figures 1 to 13 As shown, the present invention provides an electrical connector 100 based on a latch unlocking structure, comprising a plug end 1, a socket end 2, and a connection assembly 3. The plug end 1 comprises a plug core 11 and a first sealing cylinder 12. The plug core 11 is inserted into the first sealing cylinder 12. The outer surface of the first sealing cylinder 12 is recessed inward to form an annular mounting groove 121.

[0050] The socket end 2 includes a socket inner core 21 and a sealing seat cylinder 22. The socket inner core 21 is inserted into the sealing seat cylinder 22 and is used to connect with the plug inner core 11. The sealing seat cylinder 22 is provided with a plurality of accommodating cavities 221 at intervals along its circumference. The accommodating cavities 221 include a snap-fit ​​cavity 2211 and a rotating cavity 2212. One end of the rotating cavity 2212 extends to the side of the sealing seat cylinder 22 close to the plug end 1 so that this end is open. The other end of the rotating cavity 2212 is connected to the snap-fit ​​cavity 2211. In the direction from the rotating cavity 2212 to the snap-fit ​​cavity 2211, the projection of the rotating cavity 2212 partially overlaps with the projection of the snap-fit ​​cavity 2211.

[0051] The connecting assembly 3 includes a mounting ring 31, an elastic member 32, and a latch block 33 corresponding to the accommodating cavity 221. The mounting ring 31 and the elastic member 32 are installed in the mounting groove 121 in abutment with each other, and the mounting ring 31 is close to the socket end 2. The elastic member 32 is configured to always apply an elastic force toward the socket end 2 to the mounting ring 31. Several latch blocks 33 are arranged at intervals along the circumference of the first sealing cylinder 12. The latch block 33 is configured to be able to rotate in the rotating cavity 2212. The latch block 33 includes a connecting portion 331 and a clamping portion 332 that are connected to each other. The connecting portion 331 is connected to the side of the mounting ring 31 away from the elastic member 32. The clamping portion 332 is configured to be able to be inserted into the clamping cavity 2211 from the connection between the clamping cavity 2211 and the rotating cavity 2212.

[0052] Through the above technical solution, first, the plug end 1 and the socket end 2 of the present invention can be reliably connected through the connecting component 3, with excellent locking effect, and are unlikely to loosen during daily use, which can effectively ensure the stability of the electrical connection.

[0053] Second, the structures of the plug end 1 and the socket end 2 of the present invention are simple, and are entirely contacts and insulating parts for achieving conduction, without any other additional components. At the same time, the structure of the connecting component 3 of the present invention is also simple. The connecting component 3 is arranged on the plug end 1, and achieves a stable and reliable connection through the limiting effect of the accommodating cavity 221 arranged in the sealing seat cylinder 22 and the elastic part 32 arranged. It can ensure that the contacts for achieving conduction and the insulating parts for ensuring safety account for the vast majority of the entire structure, which can effectively improve the energy-saving and environmental protection effects, and has good product practicality and aesthetics.

[0054] To facilitate understanding by relevant technical personnel, the connection and disconnection processes of the electrical connector 100 based on the latch unlocking structure of the present invention are described below with reference to the accompanying drawings.

[0055] First, when the plug end 1 and the socket end 2 need to be connected, the operator can hold Figure 3 The plug end 1 shown in FIG. 1 (specifically, the operator can hold the first sealing cylinder 12 of the plug end 1 with one hand), press the mounting ring 31 toward the elastic member 32 so that the elastic member 32 is compressed, and then align the latch block 33 with the plug end 1 as shown in FIG. Figure 2The locking mechanism 332 of the latch block 33 is then released, and the locking mechanism 332 of the latch block 33 is then released. Figure 9 ), at this point, the connection between the socket end 2 and the plug end 1 is completed.

[0056] In this process, it should be noted that when the socket end 2 and the plug end 1 are in the docking state (see Figure 1 ), the axial locking of the socket end 2 and the plug end 1 is achieved by the mutual limitation of the clamping part 332 and the sealing seat cylinder 22 forming the clamping cavity 2211, and the circumferential locking of the socket end 2 and the plug end 1 is achieved by the mutual friction between the clamping part 332 and the sealing seat cylinder 22 forming the clamping cavity 2211 (it can be understood that in order to further enhance the circumferential locking, the fitting form of the clamping part 332 and the clamping cavity 2211 can be set to an interference fit).

[0057] When the plug end 1 and the socket end 2 need to be disconnected, the mounting ring 31 can be rotated first so that the latch block 33 moves to the portion where the projections of the engaging cavity 2211 and the rotating cavity 2212 overlap, and then the plug end 1 and the socket end 2 can be directly disconnected from each other.

[0058] In this embodiment, it should be noted that, first, Figure 1 As shown, when the plug end 1 and the socket end 2 of the present invention are connected by the connecting assembly 3, the overall volume is small, and only part of the mounting ring 31 and the elastic part 32 are exposed in the entire appearance, which is very convenient for decoration and daily use, and has good product practicality and aesthetics.

[0059] Secondly, the plug inner core 11 and the socket inner core 21 of the present invention can themselves have a certain insulation kit to further ensure safety, and only the conductor needs to be exposed at the joint part of the two to facilitate conduction.

[0060] Third, in actual use, the rotation direction (locking direction and unlocking direction) can also be marked on the mounting ring 31 to facilitate operators to connect and disconnect more quickly and accurately. The present invention does not impose specific limitations on this.

[0061] In one embodiment of the present invention, Figures 9 and 10 As shown, the connecting assembly 3 of the present invention may further include an elastomer 34, which is arranged in the snap-fit ​​cavity 2211, and the elastomer 34 is located at the connecting portion between the snap-fit ​​cavity 2211 and the rotating cavity 2212, so that when the snap-fit ​​portion 332 is inserted into the snap-fit ​​cavity 2211, it can enter the area in the snap-fit ​​cavity 2211 that does not overlap with the projection of the rotating cavity 2212 under the action of the elastomer 34.

[0062] In this way, the elastic member 34 thus configured can, on the one hand, provide the operator with a tactile feedback (when the operator needs to press the engaging portion 332 against the elastic member 34 and engage it into the engaging cavity 2211, the operator can use this tactile feedback to determine whether the engaging portion 332 is in contact with the elastic member 34 or whether the engaging portion 332 has entered the engaging cavity 2211), making it easier for the operator to determine the position and status of the engaging portion 332 when the operator cannot visually observe it. On the other hand, the circumferential locking effect between the plug end 1 and the socket end 2 can be further enhanced. Specifically, when the engaging portion 332 is located within the engaging cavity 2211, the elastic member 32 can provide a certain amount of circumferential support for the engaging portion 332, thereby enhancing the stability of the circumferential locking between the socket end 2 and the plug end 1.

[0063] In this embodiment, on the basis of providing the elastic body 34 , the snap-fit ​​portion 332 can be configured to be interference fit with the snap-fit ​​cavity 2211 to further enhance the stability of the circumferential locking between the socket end 2 and the plug end 1 .

[0064] In one embodiment of the present invention, Figure 11 As shown, the periphery of the elastomer 34 of the present invention may include a first side 341, a second side 342, a third side 343 and a fourth side 344 connected end to end, the first side 341 and the second side 342 are respectively connected to the peripheral wall of the clamping cavity 2211, the third side 343 is formed as a flat surface and is used to abut against the clamping portion 332 when located in the clamping cavity 2211, the fourth side 344 is formed as an arc-shaped surface, and in the direction from the connection between the fourth side 344 and the first side 341 to the connection between the fourth side 344 and the third side 343, the thickness of the elastomer 34 corresponding to the fourth side 344 gradually decreases.

[0065] In this way, the fourth side surface 344 thus set can provide directional guidance for the snap-in portion 332, so that the snap-in portion 332 can be more easily guided into the snap-in cavity 2211 during the process of extruding the elastomer 34; at the same time, the third side surface 343 thus set can provide more effective support for the snap-in portion 332 to ensure the stability of the circumferential locking of the socket end 2 and the plug end 1.

[0066] In this embodiment, the portion of the engaging portion 332 that contacts the elastic body 34 when the engaging portion 332 is engaged with the engaging cavity 2211 may be configured as a rounded structure (see FIG. Figure 4 As shown), it is easier for the clamping portion 332 to enter the clamping cavity 2211 while squeezing the elastic body 34, and avoid causing structural damage to the elastic body 34.

[0067] In one embodiment of the present invention, Figure 2 、 Figure 3 、 Figures 6 to 8 As shown, the plug end 1 of the present invention may further include a second sealing tube 13 arranged between the plug core 11 and the first sealing tube 12, the second sealing tube 13 is sleeved outside the plug core 11 and passed through the first sealing tube 12, wherein in the vertical direction, the projection of the second sealing tube 13 falls within the projection of the first sealing tube 12; at the same time, the socket end 2 may further include a first convex ring 23 arranged between the socket core 21 and the sealing seat tube 22, the first convex ring 23 is sleeved outside the socket core 21 and passed through the sealing seat tube 22, the end face of the first convex ring 23 close to the plug end 1 is used to abut against the second sealing tube 13, and the first convex ring 23 is used to be sleeved outside the plug core 11 and used to be passed through the first sealing tube 12.

[0068] In this way, the second sealing tube 13 and the first convex ring 23 thus provided can not only more effectively protect the socket inner core 21 and the plug inner core 11 when docked, thereby improving the insulation performance of the electrical connection based on the latch unlocking structure of the present invention, but also form a longer seepage path, thereby further improving the safety and service life of the electrical connection based on the latch unlocking structure of the present invention.

[0069] In one embodiment of the present invention, Figure 2 、 Figure 8 、 Figure 12 and Figure 13 As shown, the plug core 11 of the present invention may include an inner core body 111 and an inner core docking body 112. The inner core docking body 112 includes a first end 1121 connected to the plug core 11 and a second end 1122 close to the socket core 21. In the direction from the first end 1121 to the second end 1122, the radial dimension of the inner core docking body 112 gradually decreases; one end of the socket core 21 close to the plug end 1 is recessed inward to form a docking cavity 211 that matches the inner core docking body 112 to accommodate the inner core docking body 112.

[0070] In this way, by configuring the inner core docking body 112 and the docking cavity 211 in this manner, the contact resistance between the plug inner core 11 and the socket inner core 21 can be significantly reduced, and the risk of overheating can be reduced. At the same time, the current carrying capacity can also be improved.

[0071] More importantly, the fully enclosed inner core body 112 and cavity 211 achieve a self-centering effect, effectively alleviating contact loosening caused by vibration or thermal expansion and contraction, maintaining a long-term stable electrical connection. Furthermore, this fully enclosed contact pressure distribution reduces wear on the conductor surface during insertion and removal, slowing plating loss and improving durability.

[0072] In one embodiment of the present invention, Figure 3 As shown, in the vertical direction, the projection of the inner core docking body 112 falls between the mounting ring 31 and the clamping portion 332 .

[0073] In this way, by setting the inner core docking body 112 in this way, it can be effectively ensured that the plug inner core 11 can be within the protection range of the pin block 33, reducing the possibility of the operator contacting the plug inner core 11 during the docking process, thereby improving the safety of the electrical connector 100 based on the pin unlocking structure of the present invention.

[0074] In one embodiment of the present invention, Figure 1 As shown, the outer diameter of the mounting ring 31 of the present invention can be the same as the outer diameter of the sealing seat tube 22 , and when the plug end 1 and the socket end 2 are docked, the mounting ring 31 and the sealing seat tube 22 abut against each other.

[0075] In this way, when the socket end 2 and the plug end 1 are docked, the mounting ring 31 set in this way can better seal the docking position of the socket end 2 and the plug end 1, preventing the protruding mounting ring 31 or the sealing seat cylinder 22 from loosening or even falling off due to axial external force, thereby improving the environmental versatility of the electrical connector 100 based on the latch unlocking structure of the present invention during use (that is, it can be applied to more complex environments, for example, in an environment with multiple other connecting lines or devices, the mounting ring 31 set in this way can make the outer diameter of the docking position tend to be consistent, reducing the possibility of interference by external forces in a complex environment), thereby ensuring its safety in use.

[0076] In one embodiment of the present invention, Figures 1 to 3 、 Figure 5 and Figure 7 As shown, the electrical connector 100 based on the latch unlocking structure of the present invention may further include a plurality of snap-in components 4, the snap-in components 4 including detachably connected snap-in strips 41 and snap-in posts 42, the snap-in strips 41 in the plurality of snap-in components 4 being respectively arranged on the sealing seat tube 22 at intervals along the circumference of the sealing seat tube 22, and the snap-in posts 42 in the plurality of snap-in components 4 being respectively arranged on the first sealing tube 12 at intervals along the circumference of the first sealing tube 12.

[0077] In this way, the buckle assembly 4 thus provided can further improve the axial connection stability of the plug end 1 and the socket end 2 in the docking state, and avoid accidental contact with the mounting ring 31 that causes the socket end 2 and the plug end 1 to fall off accidentally.

[0078] In one embodiment of the present invention, Figure 2 、 Figure 5 and Figure 7 As shown, the fastening strip 41 of the present invention can be set as a flexible strip structure, one end of the fastening strip 41 is connected to the sealing seat cylinder 22, and a fastening through hole 411 is formed on the other end of the fastening strip 41; the fastening column 42 includes a coaxially connected sleeve section 421 and a limiting section 422, and the sleeve section 421 is connected to the first sealing cylinder 12 at one end away from the limiting section 422, and the radial dimension of the limiting section 422 is larger than the radial dimension of the sleeve section 421; wherein, the radial dimension of the sleeve section 421 is adapted to the radial dimension of the fastening through hole 411.

[0079] In this way, the flexible strip structure set up in this way can facilitate the connection or disassembly of the fastening strip 41 and the fastening column 42. At the same time, the sleeve section 421 and the limiting section 422 set up in this way can effectively ensure the connection stability between the fastening strip 41 and the fastening column 42.

[0080] In one embodiment of the present invention, Figure 5 As shown, the limiting section 422 of the present invention is formed into a hemispherical structure, the plane end of the hemispherical structure is connected to the sleeve section 421 , and the radial dimension of the hemispherical structure is larger than the radial dimension of the sleeve section 421 .

[0081] In this way, the limiting section 422 set in this way can not only achieve the limiting effect on the fastening strip 41, but also facilitate the insertion of the fastening strip 41 into the socket section 421 of the fastening column 42, thereby effectively improving the docking convenience between the fastening strip 41 and the fastening column 42.

[0082] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
