Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector and connector assembly. Background Technology

[0002] There are currently some connectors such as USB connectors widely used in external interconnects. However, these types of electrical connectors do not currently have a locking function, which poses a connection reliability problem. In particular, when used for communication between various sub-modules within a device, they are prone to loosening and shaking under external forces, affecting the reliability of the link connection and consequently affecting the overall operational stability of the device.

[0003] Therefore, how to improve the reliability of connector connections while ensuring ease of assembly and disassembly is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a connector and connector assembly that can improve the reliability of connector connection while ensuring convenient disassembly and assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connector includes a main housing and a locking structure movably connected to the outside of the main housing; the connector is used for electrically connecting a mating connector, and in the electrically connected state, the locking structure can be engaged with the connector and can be disengaged from the connector by moving on the main housing.

[0007] For example, the locking structure is rotatably connected to the main housing.

[0008] For example, the locking structure includes a locking housing and a locking plate fixed to the locking housing, the locking plate being used to engage with a connector, and the locking housing being rotatably connected to the main housing.

[0009] For example, a connecting lug is fixed to the outside of the main housing, and a connecting hole is provided on the connecting lug. The locking housing is rotatably connected to the connecting hole through a connecting post.

[0010] For example, the locking housing has a mounting groove facing the main housing; a portion of the locking piece is embedded in and fixed to the mounting groove to form an inset portion.

[0011] For example, the connector is positioned with the direction of the electrical connection joint as the first direction, and in the electrical connection state, the mounting groove has a slot at one end near the joint in the first direction, a portion of the locking piece extends through the slot and forms a protrusion, the protrusion being used to engage the joint; the slot is constricted to limit the position of the embedded portion.

[0012] For example, a buckle protrudes from the locking housing, and a locking hole is provided on the locking plate, with the buckle fixed to the locking hole.

[0013] For example, the locking housing has a limiting protrusion protruding from the surface of the main housing. When the locking structure swings on the main housing to disengage from the connector, it can swing up to the point where the limiting protrusion abuts against the main housing.

[0014] For example, the locking plate is provided with a resilient leg, which provides a resilient clamping force after the locking structure is engaged with the connector by pressing against the main housing.

[0015] For example, the connector is positioned in a first direction close to the direction of the electrical connection joint; in the first direction, the locking structure is rotatably connected to the main housing at its center; the locking plate has a first end in the first direction for engaging the joint, and a second end for including the support leg.

[0016] For example, the connector is positioned in a first direction with respect to the direction of the electrical connection joint; the main housing includes a first housing and a second housing in sequence in the first direction, the first housing being used to contact the joint in the electrical connection state; the outer diameter of the second housing is smaller than the outer diameter of the first housing, the locking housing is rotatably connected to the first housing, and the legs are supported on the second housing.

[0017] For example, the connector is positioned in a direction that is close to the electrical connection joint as a first direction; the locking tab extends from the locking housing at a first end in the first direction to form an extension for engaging the joint, the extension being elastic.

[0018] For example, the two locking structures are symmetrically arranged on both sides of the main housing.

[0019] For example, at least a portion of the locking structure is elastic, and the locking structure has a hook; during the process of the connector approaching to electrically connect the joint, the mating structure on the joint overcomes the elasticity of the locking structure to push away the hook, and after the connector moves into position, the hook is reset under the elasticity of the locking structure and engages with the slot on the mating structure.

[0020] A connector assembly includes a separate connector and a connector, wherein the connector is as described above, and the outer surface of the connector is provided with a slot for engaging with the locking structure.

[0021] For example, the connector has a folded edge formed near the port edge where it is electrically connected to the connector, and the slot is formed on one side of the folded edge.

[0022] Therefore, the connector provided by this utility model is provided with a movable locking structure. By moving the locking structure relative to the main housing, the locking structure and the corresponding connector can be mechanically locked to prevent the connector and the corresponding connector from separating, thus ensuring the reliability of the electrical connection. Furthermore, by moving the locking structure relative to the main housing, the locking structure and the connector can be released from their engagement, thereby allowing the connector and the connector to be separated. This ensures convenient disassembly and assembly while improving the reliability of the connector connection. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] The core of this utility model is to provide a connector and connector assembly that can improve the reliability of connector connection while ensuring convenient disassembly and assembly.

[0052] In one specific embodiment of the connector provided by this utility model, please refer to... Figures 1 to 18 It includes a main housing 3 and a locking structure 2. The main housing 3 is provided with a connector body 1 for electrical connection with a connector 4 that is adapted to the connector.

[0053] It should be noted that, for ease of distinction, the two electrically connected parts in this application embodiment are referred to as connector and connector 4, respectively. This does not limit the type of connector 4. In essence, connector 4 can also be another connector that is compatible with the connector in this application embodiment.

[0054] The connector can be a USB connector, and the corresponding adapter 4 is a standard board-side USB connector. In other embodiments, the connector can also be a type-c connector or other electrical connectors with other functions or shapes. The adapter 4 is adapted to fit the connector.

[0055] For ease of explanation, in this embodiment, the connector and the mating connector 4 are brought closer together along the first direction X to be electrically connected, or moved away from each other to be electrically disconnected. In this case, the first direction X corresponds to... Figures 1 to 4 The up and down directions in the diagram represent the direction in which the connector and its mating connector 4 are close together for electrical connection, and the direction away from the direction in which electrical connection is disconnected. To elaborate, with... Figure 1For example, the directions for electrical connection and disconnection of the connector are opposite positive directions (i.e., downward towards the connector 4) and opposite directions (i.e., upward away from the connector 4) on the first direction X. The first direction X, the second direction Y, and the third direction Z are three directions that are perpendicular to each other. In addition, unless otherwise specified, the electrical connection in the embodiments of this application refers to the electrical connection between the connector 4 and the connector.

[0056] like Figures 1 to 4 As shown, the locking structure 2 is movably connected to the outside of the main housing 3. When the connector and the connector 4 are electrically connected, the locking structure 2 can be engaged with the connector 4 to prevent the locking structure 2 and the connector 4 from separating. Specifically, it can prevent the two from separating along the first direction X. The locking structure 2 can be moved on the main housing 3 to release the engagement with the connector 4, thereby allowing the connector to move away from the connector 4 to release the electrical connection.

[0057] This type of connector is equipped with a movable locking structure 2. By moving the locking structure 2 relative to the main housing 3, the locking structure 2 can be mechanically locked to the corresponding connector 4 to prevent the connector and the corresponding connector 4 from separating, thus ensuring the reliability of the electrical connection. Furthermore, by moving the locking structure 2 relative to the main housing 3, the locking structure 2 can also be released from the locking and connector 4, thereby allowing the connector and connector 4 to be separated. This ensures convenient assembly and disassembly while improving the reliability of the connector connection.

[0058] Regarding the connection method between the locking structure 2 and the main housing 3, such as Figures 1 to 4 As shown, the locking structure 2 is rotatably connected to the main housing 3, so that the locking structure 2 can be engaged and unlocked by reciprocating on the main housing 3. The structure is simple and easy to operate.

[0059] Specifically, in the first direction X, the middle part of the locking structure 2 is rotatably connected to the main housing 3, at which time the locking structure 2 forms a lever structure on the main housing 3. In the first direction X, one end of the locking structure 2 is used to set a snap-fit ​​structure to snap the connector 4, specifically corresponding to the end of the connector body 1 that extends out of the main housing 3 to electrically connect to the connector 4; the other end of the locking structure 2 is used as a pressing end, which the user can press to drive the locking structure 2 to swing, so that the snap-fit ​​structure of the connector is raised relative to the main housing 3 to release the snap-fit ​​from the connector 4.

[0060] The rotation center line between the locking structure 2 and the main housing 3 can be perpendicular to the first direction X, or specifically parallel to the second direction Y.

[0061] Of course, in other embodiments, the locking structure 2 can also be slidably connected to the main housing 3. Specifically, it can slide along the first direction X. After the connector and the joint 4 are electrically connected, the locking structure 2 can slide on the main housing 3, so that the snap-fit ​​end of the locking structure extends into the groove on the joint 4. The snap-fit ​​joint deforms and extends into the groove, realizing snap-fit ​​and compression engagement with the groove. When it is necessary to release the electrical connection, the user applies an external force to the locking structure 2 to slide the locking structure 2 in the opposite direction, so that the locking structure disengages from the groove on the joint 4, releases the snap-fit, and then separates the connector and the joint 4.

[0062] Regarding the structural configuration of locking structure 2, as follows: Figures 5 to 8 As shown, the locking structure 2 includes a locking housing 21 and a locking piece 22 fixed to the locking housing 21.

[0063] Among them, such as Figure 2 and Figure 3 As shown, the locking piece 22 is used to engage with the connector 4, and the locking housing 21 is rotatably connected to the main housing 3. At this time, the locking housing 21 is used to achieve separate assembly with the main housing 3 and the locking piece 22, and is also used for direct contact and pressing by the user to unlock. The locking piece 22 is used to engage with the connector 4. The locking housing 21 and the locking piece 22 can be structurally designed according to different functional requirements, which can reduce the difficulty of processing.

[0064] The locking housing 21 and the locking plate 22 are detachably connected, for example by plugging, snapping, or bolting, so that either the locking plate 22 or the locking housing 21 can be replaced separately when either structure is severely worn, thus making full use of different structures.

[0065] Of course, in other embodiments, the locking structure 2 may be a one-piece structure, such as direct one-piece injection molding.

[0066] Regarding the structural configuration of the locking housing 21, such as Figure 7 Install to Figure 11 , Figure 16 As shown, the locking housing 21 includes a main housing 213 and housing side plates 212 fixedly disposed on the main housing 213 and disposed on the edge of the main housing 213. The housing side plates 212 protrude from the side of the outer main housing facing the main housing 3. At this time, a mounting groove 211 is formed on the side of the locking housing 21 facing the main housing 3, specifically formed between the housing side plates 212. The locking piece 22 is installed on the side of the locking housing 21 facing the main housing 3. In addition to being positioned and protected by the mounting groove 211, the side of the mounting groove 211 facing the main housing 3 is open, which also facilitates the assembly of the locking piece 22.

[0067] The locking housing 21 can be made of plastic, specifically it can be integrally molded, or it can be made of metal in other embodiments.

[0068] To achieve the connection between the locking outer shell 21 and the main shell 3, such as Figure 7 and Figure 8 As shown, a connecting lug 33 is fixed to the outside of the main housing 3, and a connecting hole 331 is provided on the connecting lug 33. The locking housing 21 is rotatably connected to the connecting hole 331 through the connecting post 34. The structure is simple and easy to assemble. Specifically, in the first direction X, a housing hole 2124 is provided in the middle of the locking housing 21. The connecting post 34 passes through the connecting hole 331 and the housing hole 2124 to serve as a connecting part and a fulcrum for the locking housing 21 and the locking structure 2 relative to the main housing 3, so that the locking structure 2 acts as a lever, and the locking structure 2 swings back and forth relative to the main housing 3 by means of the lever principle.

[0069] like Figure 7 and Figure 9 As shown, the outer shell side plate 212 includes a first side plate 2121 and a second side plate 2122. The two second side plates 2122 are disposed at both ends of the outer shell main plate 213 in the second direction Y. The first side plate 2121 is disposed at one end of the outer shell main plate 213 in the first direction X, specifically the end away from the connector 4 in the electrical connection state. The other end in the first direction X forms a slot 2111, and the slot 2111 is located between the two second side plates 2122.

[0070] like Figure 7 and Figure 8 As shown, in the outer shell side plate 212, two second side plates 2122 are provided with outer shell holes 2124. During the assembly of the locking structure 2 and the main shell 3, the two second side plates 2122 are fastened to the corresponding connecting lugs 33 on both sides in the second direction Y. The connecting post 34 passes through the connecting hole 331 and the outer shell hole 2124 in the second direction Y, and clamps the second side plate 2122 and the connecting lug 33 through the ends 341 at both ends of the connecting post 34, thereby achieving a limit in the second direction Y to prevent the connecting post 34 from disengaging from the locking structure 2 and the connecting lug 33. Specifically, the connecting post 34 may include a bolt and nut assembly, in which case one end 341 is the head of a bolt and the other end 341 is a nut.

[0071] like Figure 9 As shown, a portion of the locking piece 22 can be embedded and fixed in the mounting groove 211 to form an embedded portion 222, mainly used to fix the locking piece 22 on the locking housing 21, and the locking housing 21 can protect the embedded portion 222 of the locking piece 22; another portion of the locking piece 22 extends out through the slot 2111 of the mounting groove 211 in the first direction X to form an extension portion 224, mainly used to achieve snap-fit ​​with the connector 4. Of course, in other embodiments, the locking piece 22 can also be completely built into the mounting groove 211.

[0072] like Figure 9 and Figure 16 As shown, in the mounting groove 211 between the outer casing side plate 212 and the outer casing main plate 213, the inner portion 222 of the locking piece 22 is embedded in the mounting groove 211 and is adapted to the shape of the mounting groove 211 to further improve the reliability of the connection between the locking piece 22 and the locking outer casing 21. For example, the edge of the inner portion 222 can fit with at least a part of the surface of the outer casing side plate 212. In addition, the surface of the inner portion 222 facing away from the main casing 3 fits with the outer casing main plate 213.

[0073] like Figure 9 and Figure 16 As shown, the groove 2111 of the mounting groove 211, which is far from the first side plate 2121 in the first direction X, is tapered to limit the inner part 222, prevent the locking piece 22 from coming out of the groove 2111 along the first direction X, and improve the reliability of positioning.

[0074] like Figure 9 and Figure 11 As shown, a buckle 2113 protrudes from the mounting groove 211, specifically positioned on the surface of the main housing 213 facing the main housing 3. A locking hole 223 is provided on the locking plate 22, and the buckle 2113 is fixed to the locking hole 223 to achieve a fixed connection between the locking housing 21 and the locking plate 22. Specifically, in the first direction X, multiple buckles 2113 are sequentially arranged, for example, two, to respectively engage with different locking holes 223 on the locking plate 22, ensuring engagement stability. Alternatively, the buckle 2113 can be a bolt. During assembly, the locking plate 22 can be first installed on the locking housing 21, specifically by assembling the embedded part 222 into place in the mounting groove 211, and then the corresponding bolts are used to fix the locking plate 22 to the main housing 213.

[0075] like Figure 11 As shown, a limiting protrusion 2123 protrudes from the surface of the locking housing 21 facing the main housing 3. Specifically, the limiting protrusion 2123 is disposed on the first side plate 2121. Figure 4 As shown, when the locking structure 2 swings on the main housing 3 to disengage from the connector 4, it can swing up to the point where the limiting protrusion 2123 abuts against the main housing 3. At this time, by separately adding the limiting protrusion 2123 to limit the extreme position of the swing of the locking structure 2 during the unlocking process, the swing of the locking structure 2 can be controlled as needed.

[0076] Regarding the structural design of the locking piece 22, as follows: Figures 7 to 15 As shown, the locking piece 22 includes an embedded portion 222, an extended portion 224, and an elastic support leg 221.

[0077] The locking plate 22 can be made of sheet metal with a certain thickness, forming a one-piece structure. During processing, the sheet metal is selected and cut and bent to form the support leg 221, the embedded part 222, and the protruding part 224, as well as the hook 2241 on the protruding part 224 that engages with the connector 4. In addition, the hook 2241 can also be stamped at the end of the protruding part 224 to increase the mechanical strength of the hook 2241 and prevent deformation under stress. At this time, the locking requirements and the locking state are achieved by utilizing the elastic deformation characteristics and metal strength characteristics of the sheet metal. The locking plate 22 as a whole is elastic, realizing the purpose of automatic locking and convenient unlocking.

[0078] When assembling with the locking housing 21, a plastic mold can be used to form the locking housing 21. After the locking piece 22 is processed, the inner part 222 is embedded in the mounting groove 211. The locking piece 22 is fastened to the locking housing 21 by the buckle 2113 on the mounting groove 211, thus completing the assembly.

[0079] In this embodiment, the locking plate 22 is elastic as a whole. In other embodiments, it may only be elastic in the support leg 221. Alternatively, in other embodiments, the locking plate 22 may not have an elastic portion. In this case, a damping element is provided at the pivot between the locking structure 2 and the main housing 3. By applying an external force, the locking structure 2 is driven to swing back and forth relative to the main housing 3 to achieve engagement and disengagement with the connector 4. The damping element also positions the angular relationship between the locking structure 2 and the main housing 3. Alternatively, the locking plate 22 may not be elastic as a whole, but the locking structure 2 may additionally include an elastic element, such as a torsion spring connected to the connecting post 34, to replace the support leg 221 in this application and achieve the same application of elasticity.

[0080] like Figure 3 and Figure 8 As shown, the outrigger 221 is elastic. By pressing against the main housing 3, the outrigger 221 provides an elastic clamping force to ensure reliable engagement after the locking structure 2 is engaged with the connector 4.

[0081] like Figure 4As shown, the limiting protrusions 2123 on the locking housing 21 can be adapted to the structure of the support leg 221. When the locking structure 2 is in a free state without external force, the support leg 221 can also be in a free state without deformation, and there is a gap between the limiting protrusions 2123 and the main housing 3 to ensure that the locking structure 2 can be pressed towards the main housing 3 to unlock. Specifically, when the connector 4 and connector are engaged, the support leg 221 is supported on the main housing 3. At this time, the gap between the limiting protrusions 2123 and the main housing 3 is set according to the degree of deformation required for the support leg 221 to unlock, ensuring that when the limiting protrusions 2123 contact the main housing 3, the hook 2241 is just completely disengaged from the slot 41 or disengaged from the slot 41 by a set distance. This ensures that unlocking is possible while preventing excessive deformation of the support leg 221, thus preventing permanent deformation and loss of elasticity.

[0082] like Figure 9 As shown, the first end of the locking piece 22 in the first direction X is used to engage the connector 4. Specifically, a hook 2241 formed by flipping towards the main housing 3 can be provided to achieve engagement. The second end of the locking piece 22 in the first direction X includes a support leg 221 and a partial embedded portion 222 to ensure the reliability of the connection and to make full use of the space of the locking piece 22 in the first direction X.

[0083] like Figure 9 and Figure 11 As shown, two support legs 221 are provided in the second direction Y to provide stable elasticity. Additionally, a portion of the embedded part 222 is located between the two support legs 221 in the second direction Y, forming a first connecting part 2222 to ensure the reliability of the connection between the locking piece 22 and the support leg 221. Simultaneously, two support platforms 2112 protrude from the surface of the mounting groove 211 facing the main housing 3, respectively corresponding to one side of the two support legs 221 in the third direction Z, to limit the deformation of the support legs 221 towards the locking housing 21, preventing excessive deformation of the support legs 221. A limiting groove 2114 can be formed between the two support platforms 2112 to limit the first connecting part 2222, which is embedded within the limiting groove 2114.

[0084] like Figure 2 and Figure 13 As shown, the support leg 221 extends obliquely relative to the first direction X. One end of the support leg is away from the main housing 3 and abuts against the embedded portion 222, specifically against the arc-shaped portion 2221. The other end abuts against the main housing 3, and can always maintain abutment against the main housing 3. When the degree of deformation changes, the abutment position of the support leg 221 on the main housing 3 can slide on the main housing 3, and correspondingly, the degree of inclination of the support leg 221 relative to the first direction X changes adaptively.

[0085] like Figure 9As shown, the locking housing 21 covers the outer side of the inner part 222 and the support leg 221, specifically covering one side in the third direction X, to simultaneously protect the inner part 222 and the support leg 221. The inner part 222 also includes an arc-shaped portion 2221, which wraps around the side of the connecting post 34 away from the main housing 3, thereby improving the stability of the locking structure 2's rotation while reducing the assembly difficulty between the connecting post 34 and the locking structure 2.

[0086] Regarding the structural design of the main housing 3, such as Figure 4 , Figure 6 , Figure 7 and Figure 17 As shown, the main housing 3 includes a first housing 31 and a second housing 32 in the first direction X. The first housing 31 is used to contact the connector 4 in the electrical connection state. The connector body 1 extends out from the end of the first housing 31 away from the first housing 32.

[0087] Among them, such as Figure 4 As shown, the outer diameter of the second housing 32 is smaller than the outer diameter of the first housing 31. Specifically, the outer diameter refers to the dimension along the arrangement direction of the main housing 3 and the locking structure 2. For example, if the main housing 3 and the locking structure 2 are arranged sequentially along the third direction Z, the outer diameter refers to the dimension along the third direction Z. The locking outer shell 21 is rotatably connected to the first housing 31, and the support leg 221 is supported on the second housing 32. At this time, the support leg 221 and the second housing 32 can ensure the stability of the connection between the locking structure 2 and the second housing 32, and can ensure sufficient space between the locking structure 2 and the second housing 32 for the locking structure 2 to swing towards the second housing 32 when unlocking.

[0088] In addition, the main shell 3 can be manufactured using a one-piece plastic molding process, for example, by molding with plastic material in one piece, without the need for assembly.

[0089] During the engagement process between locking structure 2 and connector 4, such as Figure 5 and Figure 6 As shown, the protrusion 224 extends out of the locking housing 21 in the first direction X. The hook 2241 at the end of the protrusion 224 has a certain distance from the locking housing 21 in the first direction X, which can provide space for the protrusion 224 to elastically deform. This can ensure that even if the swing amplitude is insufficient during the process of the locking structure 2 engaging the connector 4, the protrusion 224 can pass over the periphery of the docking structure by changing the degree of deformation, and then be engaged with the slot 41 of the docking structure by elastic reset.

[0090] Furthermore, as the connector approaches the electrically connected joint 4, the mating structure on the joint 4 overcomes the elastic force of the locking structure 2 and pushes open the hook 2241. After the connector moves into position, the hook 2241 engages with the slot 41 on the mating structure under the elastic force of the locking structure 2. In other words, during the electrical connection process, there is no need for the user to provide external force to the locking structure 2. The connector 4 can move directly by overcoming the elastic force on the locking structure 2 through the mating structure. At the same time as the electrical connection, the joint 4 also engages with the locking structure 2, which improves the engagement efficiency and facilitates the engagement process.

[0091] To improve the reliability of the engagement between the connector 4 and the connector, two locking structures 2 are symmetrically arranged on both sides of the main housing 3. When unlocking, the locking shells 21 of the two locking structures 2 can be directly pinched at the same time to complete the unlocking operation, which can be easily achieved.

[0092] The working principle of the connector in this embodiment, which is used for assembling and disassembling with the connector 4, includes:

[0093] 1. Automatic locking: such as Figure 1 and Figure 2 As shown, the connector approaches the joint 4 along the first direction X, which corresponds to... Figure 1 As the connector moves downwards, when the protrusion 224 of the locking structure 2 contacts the mating structure on the connector 4, the mating structure 42 applies a locking hook to the protrusion 224 as the connector continues to move. Figure 1 An external force F1 causes the locking structure 2 to swing automatically. The left locking structure 2 swings clockwise or the protrusion 224 deforms continuously along this direction, while the right locking structure swings counterclockwise or the protrusion 224 deforms continuously along this direction. When the connector moves into position along the first direction X, as... Figure 2 As shown, the hook 2241 on the protrusion 224 passes over the docking structure 42 on the connector 4. The locking structure 2 resets and swings in the opposite direction under its elastic force, so that the hook 2241 is engaged in the corresponding slot 41 on the docking structure 42, thereby achieving automatic locking.

[0094] II. Maintain the locked state: such as Figure 2 As shown, the locking piece 33 has an elastic restoring force, and its support leg 221 maintains elastic support with the main housing 3, keeping the connector continuously locked to the joint 4.

[0095] III. Unlocked Status: e.g. Figure 4As shown, an external force F2 is applied to the end of the locking structure 2 away from the hook 2241, causing the support leg 221 to deform continuously under the pressure. The locking structure 2 uses the lever principle to drive the hook 2241 to lift up, and the hook 2241 moves away from and disengages from the slot 41, thereby achieving the purpose of easy unlocking. Then, by maintaining the state of pressing the locking structure 2, the connector moves away from the joint 4, and the joint 4 and the connector can be separated.

[0096] The connector provided by this utility model has the advantages of both reliable connection and convenient operation: by setting a locking structure on the connector, automatic locking can be achieved simultaneously during the electrical connection process, so that when the connector is normally inserted into the connector 4, the two can be automatically locked, which can effectively prevent the connector from loosening or falling off relative to the connector 4 due to force; during the unlocking process, the locking structure 2 can be pressed directly without any operating tools to easily unlock, achieving the purpose of simple and quick operation.

[0097] In addition to the connectors mentioned above, this utility model also provides a connector assembly, which includes a connector, specifically the connector provided in any of the above embodiments. The beneficial effects can be referred to the above embodiments accordingly.

[0098] like Figures 1 to 4 , Figure 18 As shown, the connector assembly also includes a connector 4, which is adapted to the connector for electrical connection. A slot 41 is provided on the outer surface of the connector 4 for engaging with the locking structure 2.

[0099] Specifically, such as Figure 18 As shown, the connector 4 is folded in the first direction X near the port edge of the electrically connected connector to form a folded edge 421. This folded edge 421 is a mating structure 42, and a groove 41 is formed on one side of the folded edge 421 to achieve a snap-fit ​​engagement with the locking structure 2, which facilitates processing. Specifically, the groove 41 is formed on the side of the folded edge 421 away from the connector in the first direction X.

[0100] In addition, to ensure the reliability of the snap-fit ​​locking, such as Figure 2 As shown, the port edge can be rotated 90°, specifically, after being rotated, it can be perpendicular to the first direction X, ensuring that the folded edge 421 can limit the hook 2241 in the first direction X. At this time, during the unlocking process, the hook 2241 can also be smoothly disengaged from the slot 41 by the reverse swing of the locking structure 2, so that the connector can move away from the connector 4 in the first direction X.

[0101] Specifically, the connector 4 may include a sheet metal structure, and the port near the connector in the first direction X is a sheet metal structure, which is formed by flipping to form a folded edge 421 with a slot 41.

[0102] In addition, the port edges of the connector 4 are flipped to ensure that the structure of the connector 4 is flush with the connection end of the connector. Some of the edges are flipped to form a folded edge 421 with a slot 41.

[0103] Furthermore, to ensure that the locking structure 2 can smoothly and automatically engage with the connector 4 during electrical connection, in the first direction X, the end faces of the locking structure 2 and / or the mating structure 42 that are close to each other can be arc surfaces with guiding functions, such as... Figure 1 As shown, this allows the docking structure 42 to smoothly push open the locking structure 2 after contacting it, thus achieving automatic locking.
