[0033] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating the examples of the present application.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0035] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0036] The high-current connector in the prior art includes a first connector, a second connector, and a fuse fixed between the first connector and the second connector. Since the fuse is a consumable part, it is often necessary to replace the fuse during actual use. In the prior art, if the fuse is to be replaced, an external unlocking method is conventionally adopted, that is, unlocking and locking components are set at the relative positions of the assembled first connector and the second connector, and the two connectors are directly disassembled from the outside to achieve unlocking. However, in actual applications, if the power is forgotten to be turned off, external disassembly is likely to cause leakage. Since the end of the first connector away from the second connector is electrically connected to an external device, if the first connector and the second connector are directly disassembled outside, it is easy to cause electric shock and cause harm to the human body; in addition, in order to achieve external unlocking of the two connectors, it is necessary to design a locking member with a complicated structure on the main body components of the two connectors, and the structural design is complicated.

[0037] In order to overcome the above-mentioned problems, the present application provides an unlocking connector, which includes: the present invention provides an unlocking connector and an unlocking method thereof, which include: a first connector, the first connector includes a first main body portion, the first main body portion includes a first accommodating cavity and a first plug interface, the first plug interface is located at one end of the first main body portion and is connected to the first accommodating cavity; a first terminal, located in the first accommodating cavity; the first terminal includes a first plug portion, the first plug interface exposes the first plug portion; and also includes a first locking member fixed to the first terminal; a second connector, the second connector cooperates with the first connector, the second connector includes a second locking member cooperates with the first locking member; the first terminal drives the first locking member to rotate, so that the first locking member rotates relative to the second locking member.

[0038] The first connector and the second connector of the present invention can be inserted into the first connector by a tool to act on the first terminal, driving the first locking member fixed to the first terminal to rotate in the first body part, so as to achieve locking or unlocking between the first connector and the second connector. In addition, one end of the first connector of the present invention is connected to one end of the second connector, and the other end of the first connector away from the second connector is electrically connected to the external device. The present invention needs to unlock the first connector and the second connector, and the first connector can be unplugged from the external device first. At this time, the first connector is powered off, and only needs to use a tool to insert into the first plug interface and act on the first plug-in part of the first terminal to drive the first locking member fixed to the first terminal to rotate, so as to achieve unlocking or locking between the first connector and the second connector. The unlocking method is simple and has a high safety factor. In addition, if the first connector is not directly connected to the external device but is connected to the external device through the second connector, it is not necessary to unplug the first connector first, but an external tool can be directly inserted into the plug interface of the first connector to act on the first terminal to achieve unlocking between the first connector and the second connector, and the unlocking method is simple.

[0039] The features and exemplary embodiments of various aspects of the present invention will be described in detail below.In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0040] In order to clearly illustrate structures related to the present invention, some well-known structures are hidden or transparently drawn in the figure.

[0041] Combine the following Figure 1-Figure 8 The specific structure of the locking connector is introduced in detail as follows:

[0042] Reference video Figure 1-Figure 2 The unlocking connector comprises: a first connector 1 and a second connector 2 that cooperates with the first connector 1, and a fuse 3 fixed between the first connector 1 and the second connector 2. In order to facilitate the replacement of the fuse 3, the first connector 1 and the second connector 2 can be locked or unlocked, so that the fuse can be replaced after disassembly.

[0043] refer to Figure 3-Figure 6The structural schematic diagram of the first connector 1 shown in the figure, the first connector 1 comprises a first body part 10, the first body part 10 comprises a first accommodating cavity 100 and a first plug interface 11, the first plug interface 11 is located at one end of the first body part 10 and communicates with the first accommodating cavity 100. The first body part 10 also comprises a first mounting port 12 opposite to the first plug interface 11, and at least one limiting hole 13 is provided at one end of the first body part 10 close to the first mounting port 11, and a plurality of the limiting holes are arranged on the outer wall surface of the first body part 10 and distributed along the circumference of the first body part 10; the limiting hole 13 is communicated with the first accommodating cavity 100. The limiting hole 13 comprises a first limiting edge 130 and a second limiting edge 131 which are spaced apart and distributed along the circumference of the first body part 10, so as to stop the first locking member located in the limiting hole 13 from rotating within the range of the first limiting edge and the second limiting edge.

[0044] The first terminal 20 is located in the first accommodating cavity 100. The first terminal 20 includes a first plug-in portion 21, and the first plug interface 11 exposes the first plug-in portion 21. A unlocking portion 210 is provided on the side of the first plug-in portion 21 close to the first plug interface 11, and the unlocking portion 210 is a groove or a through hole, and the unlocking portion 210 extends from the first plug-in portion 21 to a direction away from the first plug interface 11. The first plug interface exposes the unlocking portion 210. It is convenient for an external tool to be inserted into the first plug interface 11 to interact with the unlocking portion 210. The first terminal 20 also includes a first terminal base 22 connected to the first plug-in portion 21, and the first terminal base 22 is located on the side of the first plug-in portion 21 away from the plug interface 11. The first terminal base 22 is used to be fixed to the first body portion 1.

[0045] The first locking member 30 is also included, which is fixed to the first terminal 20. The first locking member 30 is fixedly connected to the first terminal base 22. The first locking member 30 can be driven to rotate by rotating the first terminal 20, and the first locking member 30 and the first terminal 20 can achieve synchronous and unidirectional rotation, so that the first connector 1 and the second connector 2 are switched between a locked state and an unlocked state.

[0046] The first locking member 30 is fixedly connected to the first terminal base 22 .

[0047] Preferably, the first locking member 30 includes at least one locking protrusion 32, which is connected to the outer wall surface of the first terminal base 22, protrudes from the outer wall surface of the first terminal base 22, and is distributed along the circumference of the first terminal base 22. The number of the locking protrusions 32 is the same as the number of the limiting holes, both of which are two and are arranged opposite to each other.

[0048] The locking protrusion 32 in this embodiment can be an integrated structure with the outer wall surface of the first terminal base 22, and the locking protrusion is directly fixed on the outer wall surface of the first terminal base 22. Specifically, the locking protrusion 32 is a protrusion structure formed by extending from the outer wall surface of the first terminal base 22 along the radial direction of the first terminal base to the side away from the outer wall surface of the first terminal base. In this way, there is no need to set up an additional first locking member separately, and only a protrusion structure needs to be set on the outer wall surface of the first terminal base of the first terminal 20. When unlocking or locking is required, the locking or unlocking function can be achieved by rotating the first terminal, which is simple in process and convenient in unlocking and locking.

[0049] Preferably, the first locking member 30 can also be provided separately, and then fixedly connected to the first terminal base 22, such a combination can also realize the rotation of the first terminal 20 to drive the rotation of the first locking member 30. The first locking member 30 includes a base 31, and a second accommodating cavity 310 provided along the axial direction of the base 31, and the second accommodating cavity 310 is provided through the base 31. The outer diameter of the first terminal base 22 is smaller than the inner diameter of the second accommodating cavity 310, and the first terminal base 22 is fixedly located in the second accommodating cavity 310 and fixed to the inner wall surface of the base 31. The first locking member 30 also includes at least one locking protrusion 32 connected to the outer wall surface of the base 31 and convexly provided on the outer wall surface of the base 31, the number of the locking protrusion 32 corresponds to the number of the limiting holes 13 on the first body part 10, and is located in the limiting hole 13, and can rotate along the circumferential direction of the first body part.

[0050] In a preferred embodiment, in order to achieve a fixed connection between the first terminal base 22 and the first locking member 30, a fixing portion 314 is convexly provided in the second accommodating cavity 310, that is, a fixing portion 314 is provided on the inner wall surface of the base of the first locking member 30. The first terminal base 22 is provided with a limiting portion 220 that cooperates with the fixing portion 314. The fixing portion 314 is a protrusion, and the limiting portion 220 is a groove; or the fixing portion 314 is a groove, and the limiting portion 220 is a protrusion.

[0051] In a preferred embodiment, the locking protrusion 32 is elastic. Specifically, the wall connected to the locking protrusion 32 and the outer wall surface 311 of the base is a cantilever 312, and there is a gap 313 between the cantilever 312 and the outer wall surface 311 adjacent to it.

[0052] Insert the first terminal 20 fixed with the first locking member 30 into the first accommodating cavity 100 from the first mounting opening 12 of the first body portion 10. Since the wall surface connected to the locking protrusion 32 is a cantilever, the inner wall surface of the first mounting opening 12 presses the locking protrusion 32 so that the locking protrusion can move into the limiting hole. When the locking protrusion 32 is located in the limiting hole 13, the force applied to the locking protrusion 32 by the inner wall surface of the first mounting opening 12 disappears, and the locking protrusion 32 rebounds and protrudes out of the limiting hole 13, and stops in the limiting hole 13 in the axial direction of the first terminal base.

[0053] Preferably, the inner diameter of the first installation opening 12 is smaller than the maximum dimension of the first locking member 30 including the locking protrusion in a first direction, and the first direction is the radial direction of the first terminal base.

[0054] In the above embodiment, in order to better insert the locking protrusion 32 into the limiting hole 13, the locking protrusion 32 further includes a guide surface 327, the guide surface 327 is located at the end of the locking protrusion 32 away from the first installation opening, and the angle between the guide surface 327 and the cantilever of the locking protrusion 32 is an acute angle. Such a design can make the inner wall surface of the first installation opening 12 contact with the guide surface 327 first when the locking protrusion 32 is inserted into the first installation opening 12 of the first body part 10, and the guide surface 327 is gradually pressed by the guide surface forming an acute angle with the cantilever to buffer the pressing force on the locking protrusion, and prevent the damage to the locking protrusion caused by the hard interference between the two.

[0055] The locking protrusion 32 of the present application can rotate along the circumference of the first body part 10 in the limiting hole 13, and when the locking protrusion 32 rotates in the clockwise direction, it stops at the second limiting edge 131 of the first limiting hole 13; when the locking protrusion 32 rotates in the counterclockwise direction, it stops at the first limiting edge 130 of the first limiting hole 13. In this way, the locking or unlocking between the limiting protrusion and the second connector can be achieved.

[0056] refer to Figure 5 The structural schematic diagram of the first locking member of the first connector is shown in FIG.

[0057] The locking protrusion 32 protrudes from the outer wall of the cantilever 312 along the radial direction of the base 31 to a side away from the outer wall of the cantilever 312. The locking protrusion 32 includes an outer side surface 320 opposite to the cantilever 312, and a first longitudinal side surface 321, a second longitudinal side surface 322, and a third longitudinal side surface 323 respectively connected to the cantilever 312, and the first longitudinal side surface 321, the second longitudinal side surface 322, and the third longitudinal side surface 323 are respectively perpendicular to the outer wall of the cantilever 312 and the outer side surface 320.

[0058] In the following, the locking protrusion 32 is located in the limiting hole 13, and the first installation opening 12 of the first body portion is used as a reference. The first longitudinal side surface 321 is arranged close to the first installation opening 12, and the second longitudinal side surface 322 is arranged opposite to the third longitudinal side surface 323. The locking protrusion 32 also includes a first protrusion guide slope 324 connecting the first longitudinal side surface 321 and the outer side surface 320, a second protrusion guide slope 325 connecting the outer side surface 320 and the second longitudinal side surface 322, and a third protrusion guide slope 326 connecting the second longitudinal side surface 322 and the third longitudinal side surface 323. The first protrusion guide slope 324 forms an obtuse angle with the first longitudinal side surface 321 and the outer side surface 320 respectively; the second protrusion guide slope 325 forms an obtuse angle with the outer side surface 320 and the second longitudinal side surface 322 respectively; and the third protrusion guide slope 326 forms an obtuse angle with the second longitudinal side surface 322 and the third longitudinal side surface 323 respectively. The setting of the obtuse angle makes it easier for the locking protrusion 32 to be inserted into the second connector, and can more smoothly achieve locking or unlocking action with the second connector, eliminate hard interference, and reduce damage to the connector.

[0059] The guide surface 327 is located on a side of the locking protrusion 32 away from the first mounting opening 12, and the maximum height of the guide surface 327 compared to the outer wall of the cantilever 312 is smaller than the height of the outer side surface compared to the outer wall of the cantilever 312. A height difference is formed between the outer side surface 320 and the guide surface 327, which facilitates the locking of the locking protrusion and the second connector.

[0060] refer to Figure 7-Figure 8 The second connector 2 shown. The second connector 2 is matched with the first connector 1, and the second connector 2 includes a second locking member 41 matched with the first locking member 30; the first terminal 20 drives the first locking member 30 to rotate, so that the first locking member 30 rotates relative to the second locking member 41, so as to achieve unlocking or locking between the first connector 1 and the second connector 2.

[0061] The second connector 2 includes a second body portion 40 , which includes a third accommodating cavity 400 , a second plug port 402 and a second mounting port 401 . The second plug port 402 and the second mounting port 401 are respectively located at two ends of the second body portion 40 and are both connected to the third accommodating cavity 400 .

[0062] The second locking member 41 is disposed on the inner wall of the second body portion 40 and is disposed near the second mounting opening 401. When the first connector 1 and the second connector 2 are plugged into each other, they can interfere with the limiting protrusion 32 in the limiting hole disposed near the first mounting opening 12 of the first connector.

[0063] The second locking member 41 is a locking groove that cooperates with the locking protrusion 32, and includes an entrance groove 42 close to the second installation port 401, and a locking groove 43 located on the side of the entrance groove 42 away from the second installation port 401. A blocking protrusion 44 is provided between the entrance groove 42 and the locking groove 43, and the blocking protrusion 44 is located on the side of the entrance groove 42 as a first guiding inclined surface 440, and the first guiding inclined surface 440 extends obliquely from the top surface of the blocking protrusion 44 to the direction close to the second installation port 401 and is connected to the bottom of the entrance groove 42. The top surface of the blocking protrusion 44 refers to the surface of the blocking protrusion 44 close to the third accommodating cavity 400.

[0064] The locking groove 43 includes two opposite first side surfaces 430 arranged at intervals along the circumference of the second body portion 40, and two opposite second side surfaces 431 arranged at intervals along the axial direction of the second body portion 40. At least one of the first side surfaces 430 is an unlocking guide slope, one side of the unlocking guide slope is connected to the inner wall surface of the third accommodating cavity 400, and the other side of the unlocking guide slope is connected to the bottom surface of the locking groove 43, and the angle formed between the unlocking guide slope and the bottom surface of the locking groove 43 is greater than 90°, so as to facilitate the removal of the locking protrusion 32 from the locking groove 43 to achieve unlocking, or the movement of the locking protrusion 32 into the locking groove to achieve locking.

[0065] A preferred embodiment may further include an unlocking groove 45, which is located on one side of the locking groove 43 and is arranged with the locking groove 43 along the circumference of the second body portion 40. One side of the unlocking guide slope 430 is connected to the unlocking groove 45, and the other side of the unlocking guide slope 430 is connected to the locking groove 43. The depth of the unlocking groove 45 is less than the depth of the locking groove 43, so as to facilitate the locking protrusion to be moved out of the locking groove or into the locking groove.

[0066] When the first connector and the second connector need to be unlocked, the first terminal only needs to be rotated to drive the first locking member to slide from the locking groove 43 into the unlocking groove through the unlocking guide slope to achieve unlocking.

[0067] In a preferred embodiment, the inlet groove 42 further includes a guide slope 421 located on a side of the first guide slope 440 close to the second installation opening 401 .

[0068] When the first connector and the second connector are locked and connected, when the first connector 1 is inserted into the third receiving cavity 400 of the second connector, the locking protrusion 32 is located in the entrance groove 42, and when the locking protrusion 32 contacts the guide bevel 421, as the first connector moves further into the entrance groove 42, the guide bevel 421 can push the locking protrusion 32 into the first guide bevel 440, so as to introduce the locking protrusion into the locking groove 43, thereby realizing the locking function between the first connector and the second connector. When the first connector 1 is inserted into the third receiving cavity 400 of the second connector, the locking protrusion 32 is located in the entrance groove 42, facing the locking groove. As the first connector moves further into the entrance groove 42, the first guide bevel 440 is used to facilitate the introduction of the locking protrusion into the locking groove 43, thereby realizing the locking function between the first connector and the second connector.

[0069] In a preferred embodiment, the arc length of the limiting hole 13 of the first connector in the circumferential direction of the first body part 10 is greater than or equal to the maximum arc length of the entrance groove 42 in the circumferential direction of the second body part 41. Here, the maximum arc length of the entrance groove 42 in the circumferential direction of the second body part is the total arc length of the guiding slope and the first guiding slope (e.g. Figure 8 The arc length marked in the brackets shown in the figure). The arc length of this part of the limiting hole is actually the arc length that limits the rotation of the limiting protrusion 32 in the limiting hole. In this embodiment, no matter where the limiting protrusion is located in the limiting hole, it can achieve the locking function with the locking groove, or the unlocking function.

[0070] Specifically, the first connector 1 assembled with the first terminal 20 and the first locking member 30 is assembled with the second connector assembled with the second terminal 50. When the first mounting port 12 of the first connector is plugged into the second mounting port 401 of the second connector, the locking protrusion 32 protruding from the main body of the first connector can rotate along the circumference of the first main body in the limiting hole, and stop at the first limiting edge 130 or the second limiting edge 131 in the circumferential direction. When the locking protrusion is located at the first limiting edge 130, the locking protrusion is just arranged opposite to the locking groove 43 of the second connector. At this time, it only needs to apply a force to the first connector to push the locking protrusion into the locking groove 43 through the first protrusion guide inclined surface 324, so as to achieve the locking of the first connector and the second connector. If the first connector is inserted into the second connector, and the locking protrusion is located at a position other than the first limiting edge 130, the third protrusion guide bevel 326 of the locking protrusion 32 interferes with the guide bevel 421 of the entrance groove 42 of the second connector, and the reaction force of the guide bevel 421 on the locking protrusion causes the locking protrusion to rotate in the limiting hole to the position of the first limiting edge, so as to achieve locking with the second connector. In the embodiment of the present application, as long as the arc length of the limiting hole 13 of the first connector in the circumferential direction of the first body part 10 is greater than or equal to the maximum arc length of the entrance groove 42 in the circumferential direction of the second body part 41, the locking protrusion can be located at any position in the limiting hole, and the first connector and the second connector can be locked.

[0071] The fuse 3 is fixed between the first connector 1 and the second connector 2. Specifically, the second terminal 50 includes a second terminal base and a second terminal plug-in portion connected to the second terminal base. The second terminal base is a hollow circular ring structure, and the first terminal base 22 is a hollow circular ring structure. One end of the fuse 3 is fixed in the hollow circular ring of the first terminal base 22, and the other end of the fuse 3 is fixed in the hollow circular ring of the second terminal base. When the first mounting port 12 of the first connector 1 is plugged into the second mounting port 401 of the second connector, the fuse is fixed between the first connector and the second connector. If you want to replace the fuse, you need to disassemble the first connector and the second connector to take out the fuse. In actual application, one of the two connectors must be energized, so the first connector and the second connector cannot be directly disassembled by conventional external unlocking.

[0072] The invention of the present application eliminates live interference by first unplugging the live end connector from the external device. Alternatively, it is not necessary to unplug the connector from the external device, and a tool is used to unlock the connector that is not directly connected to the external device. The first connector of the present application can be directly electrically connected to the external device, and the other end of the first connector is connected to the second connector. The first connector can also be not directly electrically connected to the external device, but electrically connected to the external device through the second connector.

[0073] When the first connector is directly electrically connected to an external device, it is necessary to separate the first connector from the external device when unlocking. By inserting an external tool into the first plug interface of the first connector and acting on the unlocking part of the first terminal, the first terminal and the first locking member can be driven to rotate, thereby unlocking the first locking member and the second connector. The unlocking is simple and has a high safety factor. When the first connector is connected to an external device through the second connector, it is not necessary to separate the second connector from the external device. It is only necessary to insert an external tool into the first plug interface of the first connector and act on the first terminal to unlock the first locking member and the second connector. The unlocking is simple and has a high safety factor.

[0074] In addition, in order to completely prevent the electric shock hazard caused by the user directly rotating the first connector and the second connector from the outside, the embodiment of the present application also provides a stop structure to prevent external unlocking. Specifically, two first stop surfaces 14 are provided on the side of the outer wall surface of the first main body portion close to the first installation port, and the two first stop surfaces 14 and the limiting holes 13 are distributed along the circumference of the first main body portion and are staggered. Two second stop surfaces 46 opposite to the two first stop surfaces 14 are provided on the side of the second accommodating cavity 400 of the second main body portion 40 close to the second installation port, and the two second stop surfaces 46 are distributed along the circumference of the second main body portion and are staggered. The first main body portion of the first connector is inserted into the second accommodating cavity of the second connector, and the first stop surface 14 is opposite to the second stop surface 46 to limit the rotation of the first main body portion relative to the second main body portion.

[0075] The present application also discloses an unlocking method for unlocking a connection, including the first connection and the second connector described above; providing an external tool; inserting the external tool into the first plug interface and cooperating with the unlocking portion of the first plug portion; applying a force to the external tool to rotate the first terminal, which can drive the first locking member fixed to the first terminal to rotate relative to the second locking member, so that the first connector and the second connector can be unlocked or locked. In the present invention, the first connector and the second connector are locked or unlocked by only inserting a tool into the first plug interface and applying a force to the first plug portion of the first terminal, which can drive the first locking member fixed to the first terminal to rotate, thereby achieving unlocking or locking between the first connector and the second connector. The unlocking method is simple and has a high safety factor.

[0076] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. The present invention is limited only by the claims and their full scope and equivalents.
