[0038] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0039] The present application provides a plug connector 10 .

[0040] The plug connector 10 is used in conjunction with another plug connector, wherein one of the plug connector 10 and the other plug connector 10 is a male connector and the other is a female connector.

[0041] Illustratively, the connector 10 of the present application is a female connector, and the other connector that mates with it is a male connector. In other words, the connector 10 of the present application is a socket, and the other connector that mates with it is a plug.

[0042] Reference below Figures 1-10 A plug connector 10 according to an embodiment of the present application is described.

[0043] In some embodiments, as Figure 1-Figure 3 As shown, the connector 10 includes a base 11 , a latch 12 and a lock 13 .

[0044] like Figures 1-4 and Figure 10 As shown, the base body 11 forms a first slot 111 ; the ear 12 is rotatably mounted in the first slot 111 ; the lock buckle 13 is detachably mounted on the base body 11 , wherein the lock buckle 13 is used to clamp the base body 11 to lock the ear 12 .

[0045] like Figure 1-Figure 3 As shown, the base 11 also forms a second slot 112 for cooperating with another connector; the connector 10 also includes a connecting terminal 14, which is at least partially installed in the second slot 112, and the connecting terminal 14 is used to electrically connect with another connector 10; the ear 12 can switch between a first state and a second state during rotation, and the ear 12 is suitable for locking with another connector in the first state (closed state), and the ear 12 is suitable for unlocking with another connector in the second state (open state); the lock 13 is configured to clamp the base 11 when another connector 10 is inserted into the second slot 112 and connected to the connecting terminal 14, so that the ear 12 remains in the first state.

[0046] like Figure 2 and Figure 3 As shown, both ends of the base body 11 are provided with a first slot 111, that is, both ends of the base body 11 are rotatably mounted with a latch 12, and correspondingly, the two latches 12 are configured with two locks 13. Specifically, each latch 12 is locked in the first state by its adapted lock 13.

[0047] It is understandable that when two connectors are plugged into each other, the two latches of one connector are respectively locked with the two ends of the other connector, that is, the two latches will be in the insertion and removal path of the other connector, thereby preventing the other connector from easily detaching from the connector. However, in actual applications, the latches often have the problem of not being locked in place, which seriously affects the reliability and continuity of the electrical connection between the two connectors. In the related art, a common measure to address this problem is to apply glue to the latch position. Although this method improves the stability of the latch to a certain extent, it cannot effectively alleviate the abnormality of the latch not being locked in place, and there is still a high risk of unreliable connection.

[0048] In actual implementation, Figure 1-Figure 3 As shown, when the connector 10 of the present application and the matching connector 10 (not shown in the figure) are normally plugged in, the two locks 13 respectively clamp the two ends of the base body 11. When the connector 10 is subjected to external disturbances and the ear 12 shakes, even if the ear 12 has a tendency to rotate outward at this time, the outer side of the ear 12 will abut against the lock 13. Under the blocking action of the two locks 13, the two ears 12 can remain in the first state and are difficult to switch to the second state, that is, the two locks 13 make the two ears 12 continuously restricted in the position locked with the matching connector 10. In this case, the probability of the ear 12 being accidentally opened is greatly reduced. When it is necessary to remove the matching connector from the connector 10, it is only necessary to remove the two locks 13 from the base 11, that is, the two locks 13 no longer clamp the two ends of the base 11, and then rotate the two ears 12 outward to the second state. In this way, the user can freely pull out the matching connector from the second slot 112.

[0049] The connector 10 provided in the embodiment of the present application greatly reduces the risk of the ear 12 loosening under normal use through the provision of the above-mentioned lock 13, and achieves a more stable and reliable connection between the connector 10 and the matching connector, thereby maintaining the long-term stable performance of the electrical equipment. In addition, the detachable design of the clamping seat 11 by the lock 13 simplifies the overall structure of the connector 10, making it easy to manufacture and maintain, while facilitating users to quickly install or disassemble it as needed, thereby improving the flexibility and applicability of the connector 10.

[0050] In some embodiments, as Figure 4-Figure 6 As shown, the lock buckle 13 includes a main body 131 and a first connecting arm 132a and a second connecting arm 132b connected to both sides of the main body 131. The main body 131 forms a first limiting groove 13111 for limiting the outward rotation of the ear 12, and the base body 11 is suitable for being clamped between the ends of the first connecting arm 132a and the second connecting arm 132b.

[0051] The first limiting groove 13111 can be formed on the main body 131 by machining, injection molding or other molding processes, which is not limited here.

[0052] The length, width, and thickness of the first connecting arm 132 a and the second connecting arm 132 b need to be designed according to actual application requirements to have sufficient strength and rigidity to clamp the base 11 .

[0053] In this embodiment, if Figure 4-Figure 6 As shown, in the first state, at least a portion of the latch 12 is mounted within the first limiting groove 13111. When the latch 12 tends to rotate outward, the outer side of the latch 12 abuts the bottom wall of the first limiting groove 13111. The first connecting arm 132a and the second connecting arm 132b are spaced apart on either side of the main body 131 and each is cantilevered relative to the main body 131. Specifically, in the first state, the base 11 can be clamped between the free ends of the first connecting arm 132a and the second connecting arm 132b. To disassemble the latch 13, the user can apply force directly to the ends of the first connecting arm 132a and the second connecting arm 132b, or indirectly to other locations of the first connecting arm 132a and the second connecting arm 132b, in order to release the clamping force between the ends of the first connecting arm 132a and the second connecting arm 132b.

[0054] The connector 10 provided in the embodiment of the present application realizes the clamping of the base body 11 by the lock 13 and the rotation restriction of the ear 12 by the setting of the above-mentioned main body 131, the first connecting arm 132a and the second connecting arm 132b. The main body 131 cooperates with the ear 12, and the first connecting arm 132a and the second connecting arm 132b cooperate with the base body 11, so that the force of the ear 12 and the force of the base body 11 are applied to different components in the lock 13, reducing the local force of the lock 13, thereby extending the service life of the lock 13, and the clamping point is designed at the end of the first connecting arm 132a and the second connecting arm 132b, further increasing the convenience of assembly and disassembly between the lock 13 and the base body 11.

[0055] In some embodiments, as Figure 4 、 Figure 7 、 Figure 8 and Figure 10 As shown, the ends of the first connecting arm 132a and the second connecting arm 132b are both provided with a boss 1322 protruding inwardly, and the base body 11 is provided with a second limiting groove 113 for limiting cooperation with the boss 1322.

[0056] The boss 1322 can be formed at the ends of the first connecting arm 132a and the second connecting arm 132b by machining, injection molding or other molding processes. The shape of the boss 1322 can be cylindrical, prismatic or elliptical.

[0057] The second limiting groove 113 can be formed on the base 11 by machining, injection molding or other molding processes. The shape of the second limiting groove 113 can be circular, polygonal or elliptical, etc. corresponding to the boss 1322, so that the boss 1322 can be smoothly inserted into the second limiting groove 113.

[0058] It is understandable that if Figure 2 and Figure 3 As shown, during the installation of the lock buckle 13, the user can align the bosses 1322 of the first connecting arm 132a and the second connecting arm 132b with the second limiting groove 113 of the base 11, and then forcefully push the lock buckle 13 downward into place. As the bosses 1322 are gradually inserted, the second limiting groove 113 will restrain the bosses 1322. After installation is complete, the lock buckle 13 and the base 11 are locked together. The second limiting groove 113, through the bosses 1322, prevents the lock buckle 13 from easily falling off or moving from the base 11. Furthermore, during installation, once the bosses 1322 are fully engaged in the second limiting groove 113, a sound is emitted to alert the user that the lock buckle 13 is in place. This reduces the difficulty and time required to assemble the lock buckle 13 and allows for self-checking of the locking lugs 12, thereby improving user operability.

[0059] The connector 10 provided in the embodiment of the present application, through the matching design of the above-mentioned boss 1322 and the second limiting groove 113, helps to lock the lock 13 and the base body 11 with each other in the first state, plays a role in stopping the lock 13, effectively limits the movement of the lock 13, and reduces the failure rate caused by the loosening or falling off of the lock 13 during use, and can help the user to self-check the position of the ear 12, reduce the difficulty and working hours of assembling the lock 13, thereby improving the user's operability.

[0060] In some embodiments, as Figure 4 、 Figure 7 and Figure 8 As shown, the boss 1322 has a guide surface 13221 , and the guide surface 13221 is inclined inward from an end away from the first limiting groove 13111 to an end close to the first limiting groove 13111 .

[0061] The guide surface 13221 can be formed on the boss 1322 by machining, injection molding or other molding processes. Parameters such as the inclination angle, length and width of the guide surface 13221 can be adjusted and optimized according to actual application requirements to achieve optimal guiding effect and installation performance.

[0062] In actual implementation, during the installation of the lock catch 13, the guide surface 13221 first contacts the outer surface of the base 11 and gradually guides the boss 1322 into the second limiting groove 113 as the lock catch 13 is advanced. Specifically, when the boss 1322 is inserted into the second limiting groove 113, the guide surface 13221 slides along the edge of the second limiting groove 113 and gradually guides the boss 1322 to the correct installation position. This design not only makes the installation process of the lock catch 13 smoother, but also reduces damage or malfunction caused by improper installation.

[0063] The connector 10 provided in the embodiment of the present application, through the design of forming the guide surface 13221 on the boss 1322, can more easily guide the lock 13 to the correct installation position during the installation process, reduce errors or failures caused by improper installation, reduce installation difficulty and cost, and improve work efficiency.

[0064] In some embodiments, as Figure 2 、 Figure 3 、 Figure 9 and Figure 10 As shown, the main body 131 includes a first section 1311 and a second section 1312 connected to each other. The first section 1311 forms a first limiting groove 13111, and the first section 1311 is connected to the first connecting arm 132a and the second connecting arm 132b. In the first state, the first section 1311 is located above the first slot 111, and the second section 1312 is located on the side of the first slot 111 away from the connecting terminal 14.

[0065] In this embodiment, if Figure 2 、 Figure 3 、 Figure 9 and Figure 10 As shown, the first section 1311 may include a main board body and side panels bent and connected to both sides of the main board body, the first connecting arm 132a and the second connecting arm 132b can be connected to the two side panels respectively, the inner wall of the main board body forms the bottom wall of the first limiting groove 13111, the inner walls of the two side panels form the side walls of the first limiting groove 13111, at least part of the ear 12 is accommodated in the first limiting groove 13111 formed by the first section 1311, the second section 1312 is bent outward relative to the first section 1311, and the specific shape of the second section 1312 can be designed to match the end face of the seat body 11. In addition, in order to increase the structural strength of the main body 131, the outer surfaces of the first section 1311 and the second section 1312 can be reinforced, such as adding reinforcing ribs, etc., which are not limited here.

[0066] It is understood that, since the first section 1311 is located above the first slot 111 in the first state, when installing the lock catch 13, even if the user applies excessive force, the first section 1311 will press against the upper surface of the base 11, preventing the lock catch 13 from being pushed downward indefinitely by the user, thereby reducing the risk of damage to the lock catch 13. Since the second section 1312 is located on the side of the first slot 111 facing away from the connection terminal 14 in the first state, when the latch 12 tends to rotate outward, the latch 12 will push the first section 1311 outward. At this time, the second section 1312 will stop against the end surface of the base 11, thereby exerting an inward reverse force on the first section 1311. This, combined with the reverse force generated by the boss 1322 and the second limiting groove 113, jointly restricts the outward rotation of the latch 12.

[0067] In some embodiments, as Figure 4-Figure 6 As shown, the first connecting arm 132a and the second connecting arm 132b are pivotally connected to the main body 131 around their respective rotation fulcrums 133, and the rotation fulcrum 133 of the first connecting arm 132a is arranged opposite to the rotation fulcrum 133 of the second connecting arm 132b.

[0068] like Figure 4-Figure 6 As shown, the first connecting arm 132a and the second connecting arm 132b are both lever structures. Based on the principle of leverage, the first connecting arm 132a and the second connecting arm 132b each include a power arm and a resistance arm located on both sides of the rotation fulcrum 133. The power arm is used for user operation, and the resistance arm is used to clamp the base 11. Since the rotation fulcrum 133 of the first connecting arm 132a and the rotation fulcrum 133 of the second connecting arm 132b are arranged relative to each other, the first connecting arm 132a and the second connecting arm 132b are symmetrically arranged relative to the main body 131. In this case, the lock buckle 13 as a whole is similar to a clamp structure. External force (such as manual operation by the user or an automatic mechanism) can act on the power arms of the first connecting arm 132a and the second connecting arm 132b, and the resistance arms of the first connecting arm 132a and the second connecting arm 132b will expand outward, thereby releasing the base 11.

[0069] Among them, Figure 4-Figure 6 As shown, the length of the power arm can be smaller than the length of the resistance arm.

[0070] For example, the length of the resistance arm may be twice the length of the power arm.

[0071] The rotation fulcrum 133 can be realized by components such as a pin 134, a hinge or a block, which are usually installed at corresponding positions of the first connecting arm 132a, the second connecting arm 132b and the main body 131, so that the first connecting arm 132a and the second connecting arm 132b can rotate smoothly around their respective rotation fulcrums 133.

[0072] In actual implementation, when the lock 13 is in working state, the user can apply an outward or inward force to the power arm of the first connecting arm 132a and the second connecting arm 132b, so that the first connecting arm 132a and the second connecting arm 132b pivot around the fulcrum 133 and generate a larger torque to clamp or release the seat body 11.

[0073] The connector 10 provided in the embodiment of the present application adopts a lever design through the above-mentioned first connecting arm 132a and the second connecting arm 132b. The connecting arms can generate a larger torque when subjected to external force, thereby more effectively clamping the base body 11, which improves the stability and reliability of the lock 13 when assembled with the base body 11 in the first state. At the same time, the lever design also allows the user to operate the lock 13 with less force, thereby simplifying the installation and disassembly process, thereby reducing the difficulty and cost of operation and improving work efficiency.

[0074] In some embodiments, as Figure 4 and Figure 7-Figure 9 As shown, the first connecting arm 132a and the second connecting arm 132b both include an arm body 1321 and a first supporting protrusion 1331 provided on the inner wall surface of the arm body 1321, and the outer wall surfaces on both sides of the main body 131 are provided with second supporting protrusions 1332. The first supporting protrusion 1331 and the second supporting protrusion 1332 cooperate to form a rotating fulcrum 133, wherein one of the first supporting protrusion 1331 and the second supporting protrusion 1332 forms a limiting protrusion 13321, and the other forms a limiting groove 13311 for cooperating with the limiting protrusion 13321.

[0075] In this embodiment, Figure 7-Figure 9 As shown, the first supporting protrusion 1331 forms a limiting groove 13311 , and the second supporting protrusion 1332 forms a limiting protrusion 13321 .

[0076] In other embodiments, the first supporting protrusion 1331 forms a limiting protrusion 13321 , and the second supporting protrusion 1332 forms a limiting groove 13311 .

[0077] It is understood that since both the first connecting arm 132a and the second connecting arm 132b include an arm body 1321 and a first supporting protrusion 1331 provided on the inner wall of the arm body 1321, and second supporting protrusions 1332 are provided on the outer walls of both sides of the main body 131, the arm body 1321 of the first connecting arm 132a can be spaced a certain distance from the main body 131, leaving sufficient room for the first connecting arm 132a to rotate. Similarly, the arm body 1321 of the second connecting arm 132b can also be spaced a certain distance from the main body 131, leaving sufficient room for the second connecting arm 132b to rotate. The shape and size of the limiting groove 13311 match those of the limiting protrusion 13321 to achieve a good snap-fit ​​effect, while also facilitating assembly and disassembly between the first and second connecting arms 132a, 132b and the main body 131, thereby improving the maintainability of the lock buckle 13.

[0078] It should be noted that the rotating fulcrum 133 formed by the first supporting protrusion 1331 and the second supporting protrusion 1332 is the concentrated force point of the lock buckle 13 in the first state, and is very prone to fatigue damage under long-term use. In order to reduce the risk of brittle fracture of the rotating fulcrum 133, in actual design, the surfaces of the first supporting protrusion 1331 and the second supporting protrusion 1332 on both sides along the length direction of the first support arm can be designed as arc surfaces to minimize the force on the rotating fulcrum 133; the size of the first supporting protrusion 1331 and the second supporting protrusion 1332 can also be made as large as possible to improve its load-bearing capacity.

[0079] The connector 10 provided in the embodiment of the present application forms a stable and reliable rotation fulcrum 133 through the snap-fitting of the above-mentioned limiting protrusion 13321 and the limiting groove 13311, and effectively limits the rotation range of the first connecting arm 132a and the second connecting arm 132b while leaving sufficient rotation space for the first connecting arm 132a and the second connecting arm 132b, so that the first connecting arm 132a and the second connecting arm 132b operate within a predetermined angle range, reducing damage or failure caused by excessive rotation. In addition, this design makes the connection between the first connecting arm 132a and the second connecting arm 132b and the main body 131 simpler and more convenient, without the need for a complicated assembly process, thereby reducing the difficulty and time cost of installation and disassembly.

[0080] In some embodiments, as Figure 4 、 Figure 7 and Figure 8 As shown, the outer side walls of the first connecting arm 132a and the second connecting arm 132b both have an auxiliary surface 13211 , and the auxiliary surface 13211 is inclined outward from an end away from the first limiting groove 13111 to an end close to the first limiting groove 13111 .

[0081] It can be understood that, based on the auxiliary surface 13211 being inclined outward from the end away from the first limiting groove 13111 to the end close to the first limiting groove 13111, the auxiliary surface 13211 is conducive to optimizing the decomposition of the force exerted by the seat body 11 on the first connecting arm 132a and the second connecting arm 132b. In other words, the auxiliary surface 13211 helps to disperse stress and reduce the risk of deformation or damage of the first connecting arm 132a and the second connecting arm 132b when subjected to force.

[0082] The connector 10 provided in the embodiment of the present application, through the design of the above-mentioned auxiliary surface 13211, is conducive to optimizing the force distribution of the first connecting arm 132a and the second connecting arm 132b, reducing the risk of deformation or damage of the first connecting arm 132a and the second connecting arm 132b when subjected to force, and improving the holding force of the lock 13 when subjected to external disturbances.

[0083] In some embodiments, as Figure 3 and Figure 6 As shown, the lock buckle 13 is connected to the ear 12 , and the connection position between the lock buckle 13 and the ear 12 is set away from the clamping position between the lock buckle 13 and the base 11 .

[0084] It is understood that the clamping point between the lock buckle 13 and the base 11 is located at the ends of the first connecting arm 132a and the second connecting arm 132b. When the lock buckle 13 is subjected to external disturbances, in certain circumstances, the lock buckle 13 as a whole is very likely to rotate about the clamping position as the rotation axis, causing the lock buckle 13 to directly separate from the base 11 and lose its locking function on the lug 12. When the lock buckle 13 is connected to the lug 12, the lock buckle 13 and the lug 12 are integrated together. The binding force between the lock buckle 13 and the lug 12 can help stabilize the lock buckle 13 with the above-mentioned abnormal rotation tendency. Combined with the connection position of the lock buckle 13 and the lug 12 being set away from the clamping position of the lock buckle 13 and the base 11, the probability of the lock buckle 13 falling off when subjected to external disturbances is minimized.

[0085] The connector 10 provided in the embodiment of the present application has an integrated design of the lock 13 and the ear 12. When the lock 13 attempts to detach from the base 11 due to external disturbance, the connection between the lock 13 and the ear 12 serves as an additional joining point, providing additional support, effectively reducing the risk of the lock 13 directly detaching from the base 11. At the same time, the connection position away from the clamping point increases the torque to resist abnormal rotation, thereby maximizing the ability of the lock 13 to resist falling off.

[0086] In some embodiments, as Figure 3 and Figure 6 As shown, the lock buckle 13 is provided with a first sliding structure 134 , and the latch 12 is provided with a second sliding structure 121 for slidingly cooperating with the first sliding structure 134 .

[0087] The first sliding structure may include but is not limited to a pin, a slider, a pulley, a through hole or a slide groove, etc., and the second sliding structure may include but is not limited to a pin, a slider, a pulley, a through hole or a slide groove, etc. that matches the first sliding structure, and is not limited here.

[0088] For example, in some embodiments, Figure 3 and Figure 6 As shown, the first sliding structure 134 is a pin shaft, and the second sliding structure 121 is a through hole, and the pin shaft passes through the through hole.

[0089] For example, in some other embodiments, the first sliding structure 134 is a through hole, and the second sliding structure 121 is a pin shaft, and the pin shaft passes through the through hole.

[0090] The pin 134 may be cylindrical, conical or in other shapes, and the through hole 121 may be rectangular, waist-shaped or elliptical, etc., which are not limited here.

[0091] Exemplarily, the pin 134 is designed to be cylindrical, and the through hole 121 is designed to be waist-shaped.

[0092] For example, in some other embodiments, the first sliding structure 134 is a slider, the second sliding structure 121 is a slide groove, and at least a portion of the slider is accommodated in the slide groove.

[0093] For example, in some other embodiments, the first sliding structure 134 is a sliding groove, and the second sliding structure 121 is a slider, and at least a portion of the slider is accommodated in the sliding groove.

[0094] The first sliding structure 134 can be installed in the first limiting groove 13111 by snapping, plugging, threading or other methods. The first sliding structure 134 can be installed in the first limiting groove 13111 along Figure 3 The up and down directions cooperate with the second sliding structure 121, Figure 3 The unlocking direction is upward, and similarly, the locking direction is downward.

[0095] In actual implementation, when the latch 12 switches from the first state to the second state, the user can press the power arms of the first connecting arm 132a and the second connecting arm 132b inward to drive the resistance arms of the first connecting arm 132a and the second connecting arm 132b to open, the clamping force is invalid, and the lock buckle 13 is moved along the second state. Figure 3 The first sliding structure 134 can be removed from the base 11 in the unlocking direction (ie upward). Figure 3The unlocking direction (i.e. upward) in the middle slides with the second sliding structure 121. After the lock buckle 13 fails, the ear 12 can be rotated outward until the ear 12 switches to the second state. At this time, although the lock buckle 13 is separated from the base body 11, since the lock buckle 13 is integrated with the ear 12 through the first sliding structure 134 and the second sliding structure 121, the lock buckle 13 will not be completely separated from the other structures, thereby effectively avoiding the situation where the lock buckle 13 is lost after being removed from the base body 11.

[0096] The connector 10 provided in the embodiment of the present application provides a flexible and stable connection mechanism through the sliding fit design of the above-mentioned first sliding structure 134 and the second sliding structure 121, so that the lock buckle 13 can maintain a tight connection with the ear 12 even when subjected to external disturbances and is not easy to fall off. At the same time, the sliding fit design allows a certain degree of relative freedom of movement between the lock buckle 13 and the ear 12, which enables the lock buckle 13 to adapt to different installation and use conditions, and helps to improve the adaptability and reliability of the entire lock buckle 13.

[0097] The present application also provides an electrical device.

[0098] In some embodiments, the electrical device includes: a connector 10 as any one of the above.

[0099] The electrical device may be an inverter, a transformer or other electrical devices, which is not limited here.

[0100] The electrical equipment provided in the embodiment of the present application greatly reduces the risk of the ear 12 loosening under normal use through the arrangement of the above-mentioned plug-in connector 10, and achieves a more stable and reliable connection between the plug-in connector 10 and the matching plug-in connector, thereby maintaining the long-term stable performance of the electrical equipment. The detachable design of the locking latch 13 clamping the seat 11 simplifies the overall structure of the plug-in connector 10, making it easy to manufacture and maintain, while facilitating users to quickly install or disassemble it as needed, thereby improving the flexibility and applicability of the plug-in connector 10.
