Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a battery device, an electrical device and a connector structure. Background Art

[0002] A connector is a structure used to connect two active devices and transmit current or signals. Its main function is to ensure that the electrical connection between electronic equipment, electrical systems, etc. is stable and reliable, and to facilitate connection and disconnection operations, which is convenient for equipment assembly, maintenance and replacement of parts.

[0003] At present, a shell is generally added to the connector structure to protect the terminals from bending when plugging and unplugging them. However, it is easy for misoperation to cause the terminals to be unlocked and unplugged, resulting in the risk of poor contact and reducing the stability of the connector structure. Utility Model Content

[0004] The embodiments of the present application provide a battery device, an electrical device and a connector structure, which can improve the stability of the connector structure.

[0005] In the first aspect, an embodiment of the present application provides a battery device, which includes a case, a battery cell and a connector structure, wherein the battery cell and the connector structure are arranged in the case, and the connector structure includes a first terminal, an outer shell and an anti-unlocking member, the first terminal includes a terminal body and a spring arranged on the first terminal, and the spring is provided with a first connecting portion for connecting to a matching second terminal; the outer shell cover is arranged on the outer periphery of the first terminal; the anti-unlocking member passes through the outer shell and the first terminal along a first direction, the anti-unlocking member is located on one side of the spring along a second direction, the anti-unlocking member is provided with an unlocking notch along the second direction, and the unlocking notch is staggered with the spring; wherein the second direction is the pull-out direction of the first terminal and intersects with the first direction.

[0006] In the above scheme, after the first terminal is successfully connected to the second terminal, the anti-unlocking member is passed through the housing and the first terminal in sequence along the first direction. Since the unlocking notch of the anti-unlocking member and the spring sheet are misaligned, the anti-unlocking member interferes with the spring sheet, making it impossible for the first terminal to be pulled out upward. When unlocking is required, the anti-unlocking member only needs to be pushed backward along the first direction so that the unlocking notch is directly opposite to the spring sheet, and there is a moving space for the unlocking notch above the spring sheet. The first terminal can be driven by the housing to detach from the second terminal and unlock. The embodiment of the present application reduces the risk of the terminal being unlocked and pulled out due to misoperation and poor contact through the anti-unlocking member, and improves the stability of the connector structure.

[0007] In some embodiments, the shell includes a first side wall and a second side wall, the first side wall has a first through hole for inserting the anti-unlocking member; the first side wall and the second side wall are arranged opposite to each other along a first direction, and the second side wall has a second through hole for passing the anti-unlocking member through.

[0008] In the above scheme, by respectively providing the first through hole and the second through hole on the first side wall and the second side wall opposite to the shell, the anti-unlocking part can pass through the entire shell. When unlocking is required, it is convenient to push the anti-unlocking part from the outside of the shell, thereby improving the unlocking efficiency.

[0009] In some embodiments, the spring sheet includes a connecting portion and a bending portion, the connecting portion is connected to the terminal body, and the first connecting portion is arranged on the connecting portion; the bending portion is bent from the connecting portion toward the second side wall, and the unlocking notch and the bending portion are staggered.

[0010] In the above scheme, by setting the bending portion, the interference area between the anti-unlocking part and the spring sheet can be increased, thereby further reducing the risk of the terminal being unlocked and pulled out due to misoperation and poor contact, and further improving the stability of the connector structure.

[0011] In some embodiments, the shell further includes a protrusion, which is arranged circumferentially along the second through hole, and a third through hole is opened at one end of the protrusion away from the second through hole, the anti-unlocking member passes through the protrusion, and the end of the anti-unlocking member is exposed in the third through hole.

[0012] In the above solution, the protrusion can guide the movement of the anti-unlocking component along the first direction, and can also increase the movement stroke of the anti-unlocking component, increase the unlocking difficulty, and further reduce the risk of unlocking due to misoperation.

[0013] In some embodiments, a first clamping portion is provided on the anti-unlocking member, a second clamping portion is provided on the inner wall of the protruding portion, and the first clamping portion and the second clamping portion are clamped with each other.

[0016] In the above solution, by abutting the abutting portion of the anti-unlocking member against the step portion of the first side wall of the housing, the abutting portion can be accommodated in the recessed step portion, thereby improving the connection stability between the anti-unlocking member and the housing.

[0017] In some embodiments, the first terminal further includes a deformation portion arranged on the terminal body, the deformation portion is located on the side of the spring sheet facing the second terminal, and the deformation portion is used to apply force to the spring sheet when the shell is squeezed so that the spring sheet leaves the second terminal.

[0018] In the above scheme, by squeezing the shell, the shell applies pressure to the deformable part, causing the deformable part to deform and contact the spring sheet, applying force to the spring sheet so that the spring sheet retreats backward and disengages from the second terminal, thereby achieving unlocking. The unlocking method is simple and easy to operate, thereby improving the unlocking efficiency.

[0020] In the above solution, by providing the first extrusion portion on the side of the shell body facing the spring sheet, it is possible to facilitate the outer shell to apply force to the deformation portion, thereby making the unlocking process smoother and further improving the unlocking efficiency.

[0021] In some embodiments, the shell also includes a second extrusion portion, the second extrusion portion includes an extrusion body and a second extrusion end, the extrusion body is arranged on the side of the shell body facing the spring sheet, there is a gap between the extrusion body and the deformation portion, the extrusion body is used to apply a force to the deformation portion when the shell is squeezed; the second extrusion end is arranged on the extrusion body, and the second extrusion end is used to apply a force to the spring sheet when the shell is squeezed.

[0022] In the above scheme, force is applied to the deformable part by squeezing the main body, and force is applied to the spring sheet by the second squeezing end, which further increases the area of ​​the spring sheet receiving external force when unlocking, increases the ease with which the first terminal is separated from the second terminal, and further improves the unlocking efficiency.

[0023] In some embodiments, the battery device further includes a second terminal and the connector structure of any of the above embodiments, the second terminal is provided with a second connecting portion, and the first connecting portion and the second connecting portion are engaged with each other.

[0024] In the above scheme, the first connection part of the first terminal is clamped with the second connection part of the second terminal, so as to facilitate the connection and unlocking of the first terminal and the second terminal. The anti-unlocking member is passed through the housing and the first terminal in sequence along the first direction. Since the unlocking notch of the anti-unlocking member and the spring sheet are misaligned, the anti-unlocking member interferes with the spring sheet, so that the first terminal cannot be disengaged upward. When unlocking is required, it is only necessary to push the anti-unlocking member backward along the first direction so that the unlocking notch is opposite to the spring sheet, and there is a moving space for the unlocking notch above the spring sheet. The first terminal can be detached from the second terminal driven by the housing to achieve unlocking.

[0059] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0060] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device 400 is provided inside the vehicle 1000, and the battery device 400 may be provided at the bottom, head or tail of the vehicle 1000. The battery device 400 may be used to power the vehicle 1000, for example, the battery device 400 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery device 400 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0061] In some embodiments of the present application, the battery device 400 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0062] Please refer to Figure 2 , Figure 2 An exploded view of a device provided for some embodiments of the present application. The battery device 400 includes a battery case and a battery cell 60. In some embodiments, the battery case may include an upper cover 40 and a case 50, the upper cover 40 and the case 50 cover each other, and the upper cover 40 and the case 50 jointly define a receiving cavity for accommodating the battery cell 60. The case 50 may be a hollow structure with one end open, the upper cover 40 may be a plate-like structure, the upper cover 40 covers the open side of the case 50, so that the upper cover 40 and the case 50 jointly define a receiving cavity; the upper cover 40 and the case 50 may also be hollow structures with one side open, and the open side of the upper cover 40 covers the open side of the case 50. Of course, the battery case formed by the upper cover 40 and the case 50 may be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0063] At present, a shell is generally added to the connector structure. When the terminal needs to be plugged in or out, the shell applies force to the terminal and pulls the terminal out together. The shell can protect the terminal from bending when plugging and unplugging. However, it is easy for the terminal to be unlocked and pulled out due to misoperation. For example, if an external factor collides with the shell, the terminal will be unlocked, there is a risk of poor contact, and the stability of the connector structure is reduced.

[0064] In order to solve the above technical problems, an embodiment of the present application provides a connector structure. When the first terminal is successfully connected to the second terminal, the anti-unlocking member is passed through the housing and the first terminal in sequence along the first direction. Since the unlocking notch of the anti-unlocking member and the spring sheet are misaligned, the anti-unlocking member interferes with the spring sheet, making it impossible for the first terminal to be disengaged upward. When unlocking is required, it is only necessary to push the anti-unlocking member backward along the first direction so that the unlocking notch is directly opposite to the spring sheet, and there is a moving space for the unlocking notch above the spring sheet. The first terminal can be driven by the housing to detach from the second terminal to achieve unlocking. The embodiment of the present application reduces the risk of the terminal being unlocked and pulled out due to misoperation and poor contact through the anti-unlocking member, thereby improving the stability of the connector structure.

[0065] Figure 3 This is a schematic diagram of the connector structure of some embodiments of the present application; Figure 4 Schematic diagram of assembly of the first terminal and the anti-unlocking member in some embodiments of the present application; Figure 5 This is a schematic structural diagram of the first terminal of some embodiments of the present application.

[0066] Please refer to Figure 3-Figure 5In a first aspect, an embodiment of the present application provides a battery device 400, which includes a box body 50, a battery cell 60 and a connector structure 100. The battery cell 60 and the connector structure 100 are arranged in the box body 50. The connector structure 100 includes a first terminal 10, a shell 20 and an anti-unlocking member 30. The first terminal 10 includes a terminal body 11 and a spring 12 arranged on the first terminal 10, and the spring 12 is provided with a first connecting portion 121 for connecting with a paired second terminal; the shell 20 is arranged on the outer periphery of the first terminal 10; the anti-unlocking member 30 passes through the shell 20 and the first terminal 10 along a first direction X, the anti-unlocking member 30 is located on one side of the spring 12 along a second direction Y, and the anti-unlocking member 30 is provided with an unlocking notch 31 along the second direction Y, and the unlocking notch 31 is staggered with the spring 12; wherein the second direction Y is the pull-out direction of the first terminal 10 and intersects with the first direction X.

[0067] One of the first terminal 10 and the second terminal is a male terminal, and the other is a female terminal. For example, the first terminal 10 is a male terminal, and the second terminal is a female terminal. They are inserted and matched to transmit signals or current.

[0068] The first terminal 10 and the second terminal can be sheet terminals, or can also be various types such as needle terminals, spring pins, etc. The sheet terminals are suitable for electronic devices with limited space and height requirements. A first connecting portion 121 can be set on the first terminal 10, and a second connecting portion can be set on the second terminal. The first connecting portion 121 and the second connecting portion are snapped together to achieve electrical connection between the first terminal 10 and the second terminal. The first connecting portion 121 can be a protrusion protruding in the direction of the housing 20, and the second connecting portion is a through hole, through which the protrusion and the through hole cooperate with each other; or the through hole is set on the first terminal 10, and the protrusion is set on the second terminal.

[0069] The connector structure 100 can be applied to battery devices, mobile phones, automobiles, automation equipment, etc. For example, the second terminal is set on the relay of the battery device, and the first terminal 10 can be set on the interface of the battery management system or the interface of the heat exchange system.

[0070] The housing 20 may be in a rectangular parallelepiped or cylindrical shape. The housing 20 may be thin and may be a deformable structure, and may be disposed on the outer periphery of the first terminal 10. The unlocking notch 31 may match the size and shape of the spring 12. When the unlocking notch 31 moves to the top of the spring 12, the unlocking notch 31 may accommodate the spring 12, so that the spring 12 may move upward in the unlocking notch 31.

[0071] In a normal state, the first terminal 10 is electrically connected to the second terminal, the unlocking notch 31 is misaligned with the spring 12, and the unlocking notch 31 is closer to the direction of the second spring 12 relative to the spring 12. At this time, since the anti-unlocking member 30 abuts above the spring 12, the spring 12 cannot move upward, so it will not be separated from the second terminal by mistake. In the unlocked state, the unlocking notch 31 is located directly above the spring 12 due to the backward push of the anti-unlocking member 30. The housing 20 is squeezed to deform the housing 20, and a force is applied to the spring 12 to cause the spring 12 to detach from the second terminal backward, and then the housing 20 and the first terminal 10 are pulled upward at the same time to achieve unlocking.

[0072] In the above scheme, after the first terminal 10 is successfully connected to the second terminal, the anti-unlocking member 30 is passed through the housing 20 and the first terminal 10 in sequence along the first direction X. Since the unlocking notch 31 of the anti-unlocking member 30 is misaligned with the spring 12, the anti-unlocking member 30 interferes with the spring 12, so that the first terminal 10 cannot be pulled out upward. When unlocking is required, the anti-unlocking member 30 only needs to be pushed backward along the first direction X so that the unlocking notch 31 is directly opposite to the spring 12, and there is a moving space for the unlocking notch 31 above the spring 12. The first terminal 10 can be driven by the housing 20 to detach from the second terminal and unlock. The embodiment of the present application reduces the risk of the terminal being unlocked and pulled out due to misoperation and poor contact through the anti-unlocking member 30, and improves the stability of the connector structure 100.

[0073] Figure 6 This is a schematic diagram of the structure of the housing of some embodiments of the present application.

[0074] like Figure 6 As shown, in some embodiments, the housing 20 includes a first side wall 21 and a second side wall 22, and the first side wall 21 is provided with a first through hole 211 for the anti-unlocking member 30 to be inserted; the first side wall 21 and the second side wall 22 are arranged opposite to each other along the first direction X, and the second side wall 22 is provided with a second through hole 221 for the anti-unlocking member 30 to pass through.

[0075] The housing 20 is a rectangular parallelepiped, and the unlocking prevention member 30 is first inserted into the first through hole 211 of the first side wall 21, then passes through the interior of the housing, and then passes out from the second side wall 22. The end of the unlocking prevention member 30 can be exposed from the second through hole 221.

[0076] The shapes and sizes of the first through hole 211 and the second through hole 221 can match the shapes and sizes of the anti-unlocking member 30. For example, if the cross section of the anti-unlocking member 30 is a rectangle, the first through hole 211 and the second through hole 221 can also be a rectangle.

[0077] In the above scheme, by respectively providing the first through hole 211 and the second through hole 221 on the first side wall 21 and the second side wall 22 opposite to the shell 20, the anti-unlocking component 30 can pass through the entire shell 20. When unlocking is required, it is convenient to push the anti-unlocking component 30 from the outside of the shell 20, thereby improving the unlocking efficiency.

[0078] Figure 7 This is a schematic structural diagram of the first terminal from another angle of some embodiments of the present application.

[0079] like Figure 7 As shown, in some embodiments, the spring piece 12 includes a connecting portion 122 and a bending portion 123, the connecting portion 122 is connected to the terminal body 11, and the first connecting portion 121 is arranged on the connecting portion 122; the bending portion 123 is bent from the connecting portion 122 toward the direction of the second side wall 22, and the unlocking notch 31 is staggered with the bending portion 123.

[0080] The lower end of the connecting portion 122 may be connected to the terminal body 11 , and the other portion is not connected to the terminal body 11 and extends upward, so that the bending portion 123 can move freely.

[0081] The unlocking notch 31 can match the size and shape of the bending portion 123 . When the unlocking notch 31 moves to just above the bending portion 123 , the unlocking notch 31 can accommodate the bending portion 123 , so that the bending portion 123 can move upward in the unlocking notch 31 .

[0082] In the above scheme, by setting the bending portion 123, the interference area between the anti-unlocking member 30 and the spring sheet 12 can be increased, thereby further reducing the risk of the terminal being unlocked and pulled out due to misoperation and poor contact, and further improving the stability of the connector structure 100.

[0083] Figure 8 A schematic structural diagram of a connector structure from another angle in some embodiments of the present application; Fig. 9 for Figure 8 Partial schematic diagram.

[0084] Please refer to Figure 8 and Fig. 9 In some embodiments, the housing 20 further includes a protrusion 23, which is arranged in a circumferential direction of the second through hole 221. A third through hole 231 is provided at one end of the protrusion 23 away from the second through hole 221. The anti-unlocking member 30 passes through the protrusion 23, and an end of the anti-unlocking member 30 is exposed in the third through hole 231.

[0085] The protrusion 23 may be in the shape of a cuboid or a cylinder, etc. The unlocking prevention member 30 is first inserted into the first through hole 211 of the first side wall 21 , then passes through the interior of the housing 20 , then enters the protrusion 23 from the second through hole 221 , and finally passes out from the third through hole 231 .

[0086] In the above solution, the protrusion 23 can guide the movement of the anti-unlocking member 30 along the first direction X, and can also increase the movement stroke of the anti-unlocking member 30, increase the unlocking difficulty, and further reduce the unlocking risk due to misoperation.

[0087] In some embodiments, a first clamping portion 32 is disposed on the unlocking prevention member 30 , and a second clamping portion 232 is disposed on the inner wall of the protruding portion 23 . The first clamping portion 32 and the second clamping portion 232 are clamped with each other.

[0088] The first clamping portion 32 may be a protruding structure provided on the outer surface of the anti-unlocking member 30, and the second clamping portion 232 may also be a protruding structure provided on the inner wall of the protruding portion 23. The rear side of the first clamping portion 32 abuts against the front side of the second clamping portion 232 to limit the movement of the anti-unlocking member 30 along the first direction X. When unlocking is required, the anti-unlocking member 30 only needs to be pushed backward with force to disengage the first clamping portion 32 from the second clamping portion 232.

[0089] Alternatively, one of the first clamping portion 32 and the second clamping portion 232 is a protruding structure, and the other is a groove. The first clamping portion 32 and the second clamping portion 232 are clamped together by the cooperation between the protruding structure and the groove.

[0090] The first clamping portions 32 may be provided on opposite sides of the unlocking prevention member 30 , and correspondingly, two second clamping portions 232 are also provided on the inner wall of the protruding portion 23 .

[0091] The first clamping portion 32 and the second clamping portion 232 may both be triangular in shape, and the horizontal side length of the first clamping portion 32 abuts against the horizontal side length of the second clamping portion 232 to increase the abutting area. The inclined plane of the first clamping portion 32 matches the inclined plane of the second clamping portion 232, so that when the anti-unlocking member 30 is inserted into the protruding portion 23, the matching inclined planes have a guiding effect.

[0092] In the above solution, the first engaging portion 32 and the second engaging portion 232 are engaged with each other, thereby further reducing the risk of unlocking due to misoperation.

[0093] Fig.10 This is a schematic diagram of the structure of the anti-unlocking component of some embodiments of the present application; Fig.11 This is a schematic structural diagram of the housing from another angle of some embodiments of the present application.

[0094] Please refer to Fig.10and Fig.11 In some embodiments, the anti-unlocking member 30 includes an anti-unlocking body 33 and an abutment portion 34, the abutment portion 34 is arranged at the end of the anti-unlocking body 33, and the edge of the abutment portion 34 is protruding relative to the edge of the anti-unlocking body 33; the first side wall 21 is provided with a step portion 212, and the step portion 212 is recessed along the circumference of the first through hole 211 toward the direction of the second side wall 22; the abutment portion 34 abuts against the step portion 212.

[0095] The step portion 212 may be disposed around the circumference of the first through hole 211 , and the abutting portion 34 may also be disposed around the circumference of the anti-unlocking body 33 . Alternatively, the abutting portion 34 may be disposed at intervals on the outer circumference of the anti-unlocking body 33 .

[0096] In the above solution, by abutting the abutting portion 34 of the anti-unlocking member 30 against the step portion 212 of the first side wall 21 of the housing 20, the abutting portion 34 can be accommodated in the recessed step portion 212, thereby improving the connection stability between the anti-unlocking member 30 and the housing 20.

[0097] Fig.12 This is a schematic structural diagram of the first terminal at another angle according to some embodiments of the present application.

[0098] like Fig.12 As shown, in some embodiments, the first terminal 10 also includes a deformation portion 13 arranged on the terminal body 11, and the deformation portion 13 is located on the side of the spring sheet 12 facing the second terminal. The deformation portion 13 is used to apply a force to the spring sheet 12 when the housing 20 is squeezed, so that the spring sheet 12 leaves the second terminal.

[0099] The deformation portion 13 can be bent into an arc shape from the terminal body 11 , so that a deformation space is provided between the deformation portion 13 and the terminal body 11 .

[0100] The free end of the deformable portion 13 is located at one side of the spring sheet 12, and there is a gap between the deformable portion 13 and the spring sheet 12. The housing 20 can be used to apply force to the deformable portion 13, so that the free end of the deformable portion 13 pushes the spring sheet 12.

[0101] In the above scheme, by squeezing the shell 20, the shell 20 applies pressure to the deformation part 13, so that the deformation part 13 is deformed and contacts the spring piece 12, and force is applied to the spring piece 12, so that the spring piece 12 retreats and disengages from the second terminal, so that unlocking can be achieved. The unlocking method is simple and easy to operate, which improves the unlocking efficiency.

[0102] Fig.13 Schematic cross-sectional view of the connector structure of some embodiments of the present application.

[0103] like Fig.13As shown, in some embodiments, the shell 20 includes a shell body 24 and a first extrusion portion 25, and the first terminal 10 is arranged inside the shell body 24; the first extrusion portion 25 is arranged on the side of the shell body 24 facing the spring 12, and a first extrusion end 251 is arranged on the first extrusion portion 25, and there is a gap between the first extrusion end 251 and the deformation portion 13, and the first extrusion end 251 is used to apply force to the deformation portion 13 when the shell 20 is extruded.

[0104] Two spaced first extrusion parts 25 may be provided on the inner wall of the shell body 24. Meanwhile, the deformation parts 13 may be provided on both sides of the spring sheet 12. The first extrusion end 251, as a force-applying end to the deformation part 13, can deform the deformation part 13, thereby transmitting the force to the spring sheet 12.

[0105] In the above solution, by providing the first extrusion portion 25 on the side of the shell body 24 facing the spring 12 , the outer shell 20 can apply force to the deformation portion 13 , thereby making the unlocking process smoother and further improving the unlocking efficiency.

[0106] Fig.14 Schematic cross-sectional views of connector structures according to other embodiments of the present application.

[0107] like Fig.14 As shown, in some embodiments, the shell 20 also includes a second extrusion portion 26, the second extrusion portion 26 includes an extrusion body 261 and a second extrusion end 262, the extrusion body 261 is arranged on the side of the shell body 24 facing the spring 12, and there is a gap between the extrusion body 261 and the deformation portion 13, the extrusion body 261 is used to apply a force to the deformation portion 13 when the shell 20 is extruded; the second extrusion end 262 is arranged on the extrusion body 261, and the second extrusion end 262 is used to apply a force to the spring 12 when the shell 20 is extruded.

[0108] That is, the extrusion body 261 is aligned with the deformation part 13, and the second extrusion end 262 is aligned with the spring piece 12. When the housing 20 is extruded, the extrusion body 261 contacts the deformation part 13, and the deformation part 13 is deformed, so that the deformation part 13 contacts the spring piece 12, and the force is transmitted to the spring piece 12. At the same time, the second extrusion end 262 contacts the spring piece 12, and the spring piece 12 is separated from the second terminal.

[0109] In the above scheme, force is applied to the deformation part 13 by extruding the main body 261, and force is applied to the spring piece 12 by the second extrusion end 262, which further increases the area of ​​the spring piece 12 receiving external force when unlocking, increases the ease of the first terminal 10 to detach from the second terminal, and further improves the unlocking efficiency.

[0110] In some embodiments, the battery device 400 further includes a second terminal and the connector structure 100 of any of the above embodiments, the second terminal is provided with a second connecting portion, and the first connecting portion 121 is engaged with the second connecting portion.

[0111] In the above scheme, the first connection part 121 of the first terminal 10 is clamped with the second connection part of the second terminal, so as to facilitate the connection and unlocking of the first terminal 10 and the second terminal. The anti-unlocking member 30 is passed through the housing 20 and the first terminal 10 in sequence along the first direction X. Since the unlocking notch 31 of the anti-unlocking member 30 is misaligned with the spring 12, the anti-unlocking member 30 interferes with the spring 12, so that the first terminal 10 cannot be disengaged upward. When unlocking is required, it is only necessary to push the anti-unlocking member 30 backward along the first direction X so that the unlocking notch 31 is directly opposite to the spring 12, and there is a moving space for the unlocking notch 31 above the spring 12. The first terminal 10 can be driven by the housing 20 to detach from the second terminal and unlock. The embodiment of the present application reduces the risk of the terminal being unlocked and pulled out due to misoperation and poor contact through the anti-unlocking member 30, and improves the stability of the connector structure 100.

[0112] Since the connector device adopts the connector structure 100 provided in the above embodiment, it has the same technical effect and will not be described in detail here.

[0113] In some embodiments, the first connection portion 121 is protruding toward the housing 20 , and the second connection portion is a through hole.

[0114] In the above solution, the first connection portion 121 can be accommodated in the second connection portion to achieve connection between the first terminal 10 and the second terminal. This structure can facilitate the separation of the first terminal 10 from the second terminal when unlocking, thereby improving the unlocking efficiency.
