Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and particularly relates to an electrical connector based on a plug unlocking structure. Background Art

[0002] An electrical connector is an electronic component that is used to connect two or more circuits, allowing current to flow between them while enabling the circuits to be disconnected or connected at any time without being damaged. Currently, electrical connectors are widely used in various electronic devices, instruments, and systems, such as computers, mobile phones, automobiles, aircraft, etc. In the existing related technologies, for electrical connectors, there are generally connection methods such as threaded connection and plug-and-play connection.

[0003] For the plug-and-play connection method in the existing related technologies, although it has advantages such as convenient connection / disconnection operations, etc., it still has the following problems:

[0004] First, the locking effect of the existing plug-and-play connection structure is poor, and it is prone to looseness, resulting in poor connection stability.

[0005] Second, the overall volume of the existing plug-and-play connection structure is relatively large, but the contact members for conduction and the insulating members for ensuring safety only account for about half of the entire structure. In this way, it will lead to poor energy conservation and environmental protection performance of the entire product, and the practicality and aesthetics of the product are also poor. Summary of the Invention

[0006] In order to solve the technical problems in the related technologies, the present invention provides an electrical connector based on a plug unlocking structure.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] An electrical connector based on a plug unlocking structure, comprising:

[0009] A plug end, including a plug inner core and a first sealing cylinder. The plug inner core is disposed inside the first sealing cylinder, and an annular installation groove is formed by inward depression on the outer surface of the first sealing cylinder;

[0010] A socket end, including a socket inner core and a sealing seat cylinder. The socket inner core is disposed inside the sealing seat cylinder and is used to dock with the plug inner core. A plurality of accommodating cavities are arranged at intervals along the circumferential direction inside the sealing seat cylinder. The accommodating cavity includes a clamping cavity and a rotating cavity. One end of the rotating cavity extends to the side of the sealing seat cylinder close to the plug end to make this end open, and the other end of the rotating cavity is connected to the clamping cavity. In the direction from the rotating cavity to the clamping cavity, the projection of the rotating cavity coincides with a part of the projection of the clamping cavity;

[0011] The connecting component includes an installation ring, an elastic member, and pin blocks corresponding to the accommodating cavities one by one. The installation ring and the elastic member are installed in the installation groove in contact with each other, and the installation ring is close to the socket end. The elastic member is configured to always apply an elastic force towards the socket end to the installation ring. A plurality of pin blocks are arranged at intervals along the circumference of the first sealing cylinder. The pin blocks are configured to be able to rotate in the rotating cavity. The pin block includes a connecting portion and a clamping portion connected to each other. The connecting portion is connected to the side of the installation ring away from the elastic member, and the clamping portion is configured to be able to insert into the clamping cavity from the communication part between the clamping cavity and the rotating cavity.

[0012] Optionally, the connecting component further includes an elastomer. The elastomer is arranged in the clamping cavity and is located at the communication part between the clamping cavity and the rotating cavity, so that when the clamping portion inserts into the clamping cavity, it can enter the area in the clamping cavity that does not coincide with the projection of the rotating cavity under the action of the elastomer.

[0013] Optionally, the periphery of the elastomer includes a first side surface, a second side surface, a third side surface, and a fourth side surface that are connected end to end. The first side surface and the second side surface are respectively connected to the peripheral wall of the clamping cavity. The third side surface is formed as a flat surface and is used to abut against the clamping portion when it is in the clamping cavity. The fourth side surface is formed as an arc surface, and in the direction from the connection between the fourth side surface and the first side surface to the connection between the fourth side surface and the third side surface, the thickness of the elastomer corresponding to the fourth side surface gradually decreases.

[0014] Optionally, the plug end further includes a second sealing cylinder arranged between the plug inner core and the first sealing cylinder. The second sealing cylinder is sleeved outside the plug inner core and penetrates through the first sealing cylinder. Among them, in the vertical direction, the projection of the second sealing cylinder falls within the projection of the first sealing cylinder;

[0015] The socket end further includes a first convex ring arranged between the socket inner core and the sealing seat cylinder. The first convex ring is sleeved outside the socket inner core and penetrates through the sealing seat cylinder. The end surface of the first convex ring close to the plug end is used to abut against the second sealing cylinder. The first convex ring is used to be sleeved outside the plug inner core and penetrate through the first sealing cylinder.

[0016] Optionally, the plug inner core includes an inner core body and an inner core docking body. The inner core docking body includes a first end connected to the plug inner core and a second end close to the socket inner core. In the direction from the first end to the second end, the radial dimension of the inner core docking body gradually decreases;

[0017] One end of the socket inner core near the plug end is recessed inward to form a docking cavity that matches the inner core docking body for accommodating the inner core docking body.

[0018] Optionally, in the vertical direction, the projection of the inner core docking body falls between the mounting ring and the clamping portion.

[0019] Optionally, the outer diameter dimension of the mounting ring is the same as the outer diameter dimension of the sealing seat cylinder, and when the plug end is docked with the socket end, the mounting ring abuts against the sealing seat cylinder.

[0020] Optionally, the electrical connector based on the pin unlocking structure further includes a plurality of buckling components. The buckling components include a buckling strip and a buckling post that are detachably connected. The buckling strips in the plurality of buckling components are respectively arranged on the sealing seat cylinder at intervals along the circumferential direction of the sealing seat cylinder, and the buckling posts in the plurality of buckling components are respectively arranged on the first sealing cylinder at intervals along the circumferential direction of the first sealing cylinder.

[0021] Optionally, the buckling strip is arranged as a flexible strip structure. One end of the buckling strip is connected to the sealing seat cylinder, and a buckling through hole is formed at the other end of the buckling strip.

[0022] The buckling post includes a sleeved section and a limiting section that are coaxially connected. One end of the sleeved section away from the limiting section is connected to the first sealing cylinder, and the radial dimension of the limiting section is larger than the radial dimension of the sleeved section.

[0023] Wherein, the radial dimension of the sleeved section is adapted to the radial dimension of the buckling through hole.

[0024] Optionally, the limiting section is formed as a hemispherical structure. The flat end of the hemispherical structure is connected to the sleeved section, and the radial dimension of the hemispherical structure is larger than the radial dimension of the sleeved section.

[0025] Beneficial effects:

[0026] 1. Through the above technical solutions, first, the plug end and the socket end of the present invention can be reliably connected through the connection components, with excellent locking effect, and it is difficult to loosen during daily use, which can effectively ensure the stability of the electrical connection.

[0027] Second, the structures of the plug end and the socket end of the present invention are simple, and all are contact parts and insulating parts for achieving conduction, without other additional parts. At the same time, the structure of the connection assembly of the present invention is also equally simple. The connection assembly is arranged on the plug end and realizes stable and reliable connection through the limiting effect of the accommodating cavity arranged in the sealing seat cylinder and the arranged elastic parts, which can ensure that the contact parts for achieving conduction and the insulating parts for ensuring safety account for the vast majority of the whole structure, can effectively improve the energy-saving and environmental protection effects, and have good product practicability and aesthetics.

Detailed implementation manners

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here 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 claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0047] In the description of the present invention, it should be noted that the terms used, such as "first" and "second", are only for the purpose of distinguishing expressions, rather than indicating or implying any importance or sequential difference; the terms used, such as "inner" and "outer", refer to the inside and outside of the specific contour. The use of the above terms is only for the convenience of clearly and simply expressing the technical solution of the present invention and cannot be construed as a limitation of the present invention.

[0048] The following will detail the technical solution of the present invention with reference to the accompanying drawings.

[0049] As Figures 1 to 13 shown, the present invention provides an electrical connector 100 based on a plug unlocking structure, which includes a plug end 1, a socket end 2, and a connection component 3. The plug end 1 includes a plug inner core 11 and a first sealing cylinder 12. The plug inner core 11 is disposed inside the first sealing cylinder 12, and an annular installation groove 121 is formed by the inward depression of the outer surface of the first sealing cylinder 12.

[0050] The socket end 2 includes a socket inner core 21 and a sealing seat cylinder 22. The socket inner core 21 is disposed inside the sealing seat cylinder 22 and is used for docking with the plug inner core 11. A plurality of accommodating cavities 221 are arranged at intervals along the circumferential direction inside the sealing seat cylinder 22. The accommodating cavity 221 includes a clamping 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 to make this end open. The other end of the rotating cavity 2212 is communicated with the clamping cavity 2211. In the direction from the rotating cavity 2212 to the clamping cavity 2211, the projection of the rotating cavity 2212 coincides with a part of the projection of the clamping cavity 2211;

[0051] The connecting component 3 includes a mounting ring 31, an elastic member 32, and pin blocks 33 corresponding to the accommodating cavities 221 one by one. The mounting ring 31 and the elastic member 32 are mounted in the mounting groove 121 in contact 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 towards the socket end 2 to the mounting ring 31. A plurality of pin blocks 33 are arranged at intervals along the circumferential direction of the first sealing cylinder 12. The pin blocks 33 are configured to be able to rotate in the rotating cavity 2212. The pin block 33 includes a connecting portion 331 and a clamping portion 332 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 insert into the clamping cavity 2211 from the communication portion between the clamping cavity 2211 and the rotating cavity 2212.

[0052] Through the above technical solutions, first, the plug end 1 and the socket end 2 of the present invention can be reliably connected through the connecting component 3, and the locking effect is excellent. It is difficult to loosen during daily use, and the stability of the electrical connection can be effectively guaranteed.

[0053] Second, the structures of the plug end 1 and the socket end 2 of the present invention are simple, and all are contact members and insulating members for realizing conduction, without 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 realizes stable and reliable connection through the limiting effect of the accommodating cavity 221 arranged in the sealing seat cylinder 22 and the arranged elastic member 32. It can ensure that the contact members for realizing conduction and the insulating members for ensuring safety account for the vast majority of the whole structure, can effectively improve the energy-saving and environmental protection effect, and has good product practicability and aesthetics.

[0054] For the convenience of those skilled in the art to understand, the connection and disconnection processes of the electrical connector 100 based on the pin unlocking structure of the present invention will be described below with reference to the accompanying drawings.

[0055] First, when it is necessary to connect the plug end 1 and the socket end 2, the operator can hold the plug end 1 as shown in Figure 3 (specifically, the operator can hold the first sealing cylinder 12 of the plug end 1 with one hand), squeeze the mounting ring 31 towards the elastic member 32, so that the elastic member 32 is compressed, and then align the pin block 33 with the one as shown in Figure 2Insert into the accommodation cavity 221 of the socket end 2 shown (specifically, insert it into the side of the rotating cavity 2212 away from the clamping cavity 2211), and then rotate the mounting ring 31 so that the latch block 33 rotates accordingly until the clamping portion 332 of the latch block 33 aligns with the clamping cavity 2211 (that is, the latch block 33 fits on the side of the rotating cavity 2212 close to the clamping cavity 2211). Then relieve the extrusion of the elastic member 32 by the mounting ring 31 (it should be noted that at this time, the elastic member 32 still exerts an elastic force towards the socket end 2 on the mounting ring 31). The clamping portion 332 of the latch block 33 will enter the overlapping part of the clamping cavity 2211 and the projection of the rotating cavity 2212. Then slightly rotate the mounting ring 31 again so that the clamping portion 332 enters the non-overlapping part of the clamping cavity 2211 and the projection of the rotating cavity 2212 (refer to Figure 9 ). At this time, the connection between the socket end 2 and the plug end 1 is completed.

[0056] During this process, it should be noted that when the socket end 2 and the plug end 1 are in the docking state (refer to Figure 1 ), the axial locking between the socket end 2 and the plug end 1 is achieved by the mutual limitation between the clamping portion 332 and the sealing seat cylinder 22 forming the clamping cavity 2211, and the circumferential locking between the socket end 2 and the plug end 1 is achieved by the mutual frictional force between the clamping portion 332 and the sealing seat cylinder 22 forming the clamping cavity 2211 (it can be understood that to further enhance the circumferential locking, the matching form between the clamping portion 332 and the clamping cavity 2211 can be set as an interference fit).

[0057] When it is necessary to disconnect the plug end 1 and the socket end 2, the mounting ring 31 can be rotated first so that the latch block 33 moves to the overlapping part of the clamping cavity 2211 and the projection of the rotating cavity 2212, 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, as Figure 1 shown, when the plug end 1 and the socket end 2 of the present invention are under the connection of the connection component 3, the overall volume is small, and only a part of the mounting ring 31 and the elastic member 32 are exposed on the whole appearance, which is very convenient for decoration and daily use, and has good product practicability and aesthetics.

[0059] Second, 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 docking part of the two for conduction.

[0060] Third, during the actual use process, the rotation direction (locking direction and unlocking direction) can also be marked on the mounting ring 31 to facilitate the operator to perform the connection and disconnection operations more quickly and accurately. The present invention does not make specific limitations on this.

[0061] In one embodiment of the present invention, as Figures 9 to 10 shown, the connection component 3 of the present invention may further include an elastomer 34. The elastomer 34 is disposed in the clamping cavity 2211 and is located at the communicating part of the clamping cavity 2211 and the rotating cavity 2212, so that when the clamping part 332 is inserted into the clamping cavity 2211, it can enter the area in the clamping cavity 2211 where the projection does not coincide with the rotating cavity 2212 under the action of the elastomer 34.

[0062] In this way, through the elastomer 34 arranged in this way, on the one hand, it can provide a feedback touch feeling for the operator (when the operator needs to squeeze the elastomer 34 with the clamping part 332 and snap it into the clamping cavity 2211, the operator can judge whether the clamping part 332 contacts the elastomer 34 or whether the clamping part 332 enters the clamping cavity 2211 through the feedback touch feeling), which is convenient for the operator to judge its position and state when the clamping part 332 cannot be directly observed. On the other hand, it can further improve the circumferential locking effect between the plug end 1 and the socket end 2. Specifically, when the clamping part 332 is located in the clamping cavity 2211, the elastic member 32 can provide a certain support for the clamping part 332 in the circumferential direction, 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 arranging the elastomer 34, the clamping part 332 can be configured to be in interference fit with the clamping cavity 2211 to further improve the stability of the circumferential locking between the socket end 2 and the plug end 1.

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

[0065] In this way, the fourth side surface 344 arranged in this way can provide a direction guide for the clamping part 332, so that the clamping part 332 is more easily guided into the clamping cavity 2211 during the process of squeezing the elastomer 34; at the same time, by arranging the third side surface 343 in this way, it can provide more effective support for the clamping part 332 to ensure the stability of the circumferential locking between the socket end 2 and the plug end 1.

[0066] In this embodiment, for the snap - in part 332, the part that contacts the elastomer 34 when it snaps into the snap - in cavity 2211 can be set to a chamfered - corner structure (as shown in Figure 4 ), so as to more easily allow the snap - in part 332 to enter the snap - in cavity 2211 while squeezing the elastomer 34, and avoid causing structural damage to the elastomer 34.

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

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

[0069] In one embodiment of the present invention, as shown in Figure 2 , Figure 8 , Figure 12 and Figure 13 , the plug inner 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 inner core 11 and a second end 1122 close to the socket inner 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 inner 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 for accommodating the inner core docking body 112.

[0070] In this way, through the inner core docking body 112 and the docking cavity 211 arranged in this way, the contact resistance between the plug inner core 11 and the socket inner core 21 can be significantly reduced, the overheating risk can be reduced, and at the same time, the current - carrying capacity can be improved.

[0071] More importantly, the inner core docking body 112 and the docking cavity 211 arranged in this way can achieve self - centering effect through full - circumference wrapping, effectively alleviating the problem of contact loosening caused by vibration (shock) or thermal expansion and contraction, and maintaining long - term stable electrical connection. At the same time, the contact pressure distribution of full - circumference wrapping can reduce the wear on the surface of the conductor during the plug - in and unplug - out process, delay the loss of the coating, and improve the service durability.

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

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

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

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

[0076] In an embodiment of the present invention, as Figures 1 to 3 、 Figure 5 and Figure 7 shown, the electrical connector 100 based on the plug - pin unlocking structure of the present invention may further include a plurality of buckling components 4. The buckling components 4 include a buckling strip 41 and a buckling post 42 that are detachably connected. The buckling strips 41 in the plurality of buckling components 4 are respectively arranged on the sealing seat cylinder 22 at intervals along the circumferential direction of the sealing seat cylinder 22, and the buckling posts 42 in the plurality of buckling components 4 are respectively arranged on the first sealing cylinder 12 at intervals along the circumferential direction of the first sealing cylinder 12.

[0077] In this way, through the snap-fit component 4 arranged in this manner, the axial connection stability between the plug end 1 and the socket end 2 in the docked state can be further improved, and accidental detachment of the socket end 2 from the plug end 1 caused by accidental contact with the mounting ring 31 can be avoided.

[0078] In an embodiment of the present invention, as Figure 2 , Figure 5 and Figure 7 shown, the snap-fit strip 41 of the present invention can be arranged as a flexible strip structure. One end of the snap-fit strip 41 is connected to the sealing seat cylinder 22, and a snap-fit through hole 411 is formed at the other end of the snap-fit strip 41; the snap-fit post 42 includes a sleeved section 421 and a limiting section 422 connected coaxially. The end of the sleeved section 421 away from the limiting section 422 is connected to the first sealing cylinder 12, and the radial dimension of the limiting section 422 is larger than that of the sleeved section 421; wherein, the radial dimension of the sleeved section 421 is adapted to the radial dimension of the snap-fit through hole 411.

[0079] In this way, the flexible strip structure arranged in this manner can facilitate the snap-fit or disassembly between the snap-fit strip 41 and the snap-fit post 42.
