[0040] In order to avoid affecting the connection reliability between the third connector 3 and the corresponding first connector 1 when the second connector 2 is disassembled, in the technical solution adopted in the present application, the plug-in module also includes: a fixing member 4, which can be arranged on the base, and the fixing member 4 is used to realize locking and unlocking of the third connector. When the second connector 2 and the third connector 3 are respectively connected to the corresponding first connector 1, the fixing member 4 is unlocked from the third connector 3, and when the second connector 2 and the corresponding first connector 1 are disconnected, the fixing member 4 is relatively fixed to the third connector 3 to realize locking of the third connector 3 and prevent the third connector 3 from being disengaged from the corresponding first connector 3 under the drive of the second connector 2.

[0041] It should be noted that the number of the fixing members 4 can be multiple, which can specifically correspond to the number of the first connecting members 1. For example, the number of the first connecting members 1 is two, see the attached Figure 1 The number of the fixing members 4 may also be two, and the two fixing members 4 may be arranged opposite to each other and may be staggered in the plug-in direction of the second connector 2 and the third connector 3. When the second connector 2 and the third connector 3 are respectively connected to the corresponding first connector 1, the two fixing members 4 may respectively correspond to the second connector 2 and the third connector 3, and may respectively lock the other of the second connector 2 and the third connector 3 when one of the second connector 2 and the third connector 3 is removed.

[0042] The following example illustrates an implementation method: Figure 1 The base can be arranged on the board body 5, and the base can include two first connecting members 1, which can be arranged side by side on the board body 5 along the first direction. The first connecting member 1 can be a shell structure, and can form a receiving groove 101 with the board body 5 to adapt to the second connecting member 2 or the third connecting member 3. The shell can have a plug-in port 102 on one side in the second direction, and the fixing member 4 can be arranged on the top of the side of the shell away from the plug-in port 102; wherein the first direction and the second direction can be perpendicular to each other and respectively parallel to the board body 5.

[0043] For further information, see Attachment Figure 1 -Attached Figure 3 In order to realize locking and unlocking of the third connecting member 3 by the fixing member 4, in a specific implementation, the fixing member 4 has a trigger portion 41 and a first locking portion 42, the trigger portion 41 is detachably connected to the second connecting member 2, and the first locking portion 42 is detachably connected to the third connecting member 3, and the fixing member 4 is triggered when the trigger portion 41 is disconnected from the second connecting member 2, and the first locking portion 42 is connected to the third connecting member 3 after being triggered.

[0044] Specifically, in order to avoid affecting the connection reliability between the third connector 3 and the corresponding first connector 1 when the second connector 2 is disassembled, in the technical solution adopted in the present application, the plug-in module also includes: a fixing member 4, which can be arranged on a base, and the fixing member 4 can have a trigger portion 41 and a first locking portion 42; when the second connector 2 and the third connector 3 are respectively connected to the corresponding first connector 1, the position of the trigger portion 41 can correspond to the position of the second connector 2 and be detachably connected, and the position of the first locking portion 42 can correspond to the position of the third connector 3 and be detachably connected, and when the user disassembles the second connector 2 until the second connector 2 is separated from the trigger member, the trigger member can be triggered so that the first locking portion 42 of the fixing member 4 maintains a connection relationship with the third connector 3, so as to lock the position of the third connector 3 and the corresponding first connector 1, and avoid the third connector 3 being brought out when the second connector 2 is disassembled.

[0045] For further information, see Attachment Figure 1 -Attached Figure 5 In order to realize the state switching of the fixing member 4, in the specific implementation, the fixing member 4 has a first form and a second form that can be switched to each other, and the switching can be realized by position movement and / or self-deformation. When the trigger part 41 is connected to the second connecting member 2, the first locking part 42 can be disconnected from the third connecting member 3, that is, the third connecting member 3 can be in an unlocked state, and the fixing member 4 can be in the first form at this time; and when the trigger part 41 is disconnected from the second connecting member 2, the first locking part 42 can be connected to the third connecting member 3, that is, the third connecting member 3 can be in a state of being locked by the first locking part 42, and the fixing member 4 can be in the second form at this time.

[0046] In order to further realize the locking of the fixing member 4 and the third connecting member 3, refer to the attached Figure 1 -Attached Figure 5, a second locking portion 31 corresponding to the first locking portion 42 can be provided on the third connecting member 3, and when the fixing member 4 is in the first form, the first locking portion 42 of the fixing member 4 can be connected to the second locking portion 31, and correspondingly, in order to realize the connection between the first locking portion 42 and the second locking portion 31, a corresponding avoidance hole 103 can be set on the first connecting member 1; the connection mode of the first locking portion 42 and the second locking portion 31 can be plug-in, that is, a concave-convex matching connection mode, for example: the first locking portion 42 can be set to a convex structure, and the second locking portion 31 is set to a concave structure; or vice versa, that is, the first locking portion 42 is set to a concave structure, and the second locking portion 31 is set to a convex structure; below, taking the first locking portion 42 as a convex structure and the second locking portion 31 as a concave structure as an example, the first locking portion 42 can be a hook structure protruding toward the side where the first connecting member 1 is located, and the second locking portion 31 can be set to a groove corresponding to and adapted to the first locking portion 42, in order to facilitate the locking of the fixing member 4 and the third connecting member 3, refer to the attached Figure 4 and attached Figure 5 The surface of the first locking portion 42 facing the first connecting member 1 can be set as an inclined guide surface 421, and the inclination trend can be: the dimension of the first locking portion 42 in the direction perpendicular to the plate gradually increases along the direction in which the third connecting member 3 is connected to the first connecting member 1, which can help reduce the resistance of the third connecting member 3 when it is connected to the first connecting member 1 and the fixing member 4.

[0047] For further information, see Attachment Figure 1 or attached Figure 4 or attached Figure 5 In order to realize the state switching of the fixing member 4, in a specific implementation, the first end 4a of the fixing member 4 can be connected to the base, the first locking portion 42 can be located at the second end 4b of the fixing member 4, the trigger portion 41 can be located between the first end 4a and the second end 4b of the fixing member 4, and the trigger portion 41 can be rotatably connected to the first end 4a. The rotatable connection here means that the trigger portion 41 can rotate relative to the first end 4a, and is not limited to the direction of rotation. The rotation can be achieved by utilizing the connection method of the connection position of the trigger portion 41 and the first end 4a, and / or can also be achieved by the deformation of the fixing member 4 itself; when the second connecting member 2 is connected to the first connecting member 1, the second connecting member 2 can abut against the triggering portion 41 to trigger the triggering portion 41.

[0048] Among them, refer to the attached Figure 1In order to realize convenient installation or disassembly of the fixing member 4, in the technical solution adopted in the present application, the first end 4a of the fixing member 4 can be connected to the base in a detachable manner, for example, it can be connected by connecting members such as bolts or screws, and in order to improve the reliability of the fixation, two or more connecting members can be used for connection to avoid twisting or loosening of the fixing member 4.

[0049] Specifically, in order to achieve the triggering and resetting of the trigger part 41, one implementation is: the fixing member 4 can be set to a sheet structure extending along the first direction and having a certain elasticity. When the second connecting member 2 abuts against the triggering part 41, the fixing member 4 is deformed and the triggering part 41 is triggered. When the second connecting member 2 is disassembled from the first connecting member 1, that is, when the second connecting member 2 is disengaged from the triggering part 41, the fixing member 4 restores the deformation under its own elastic action and drives the first locking part 42 to connect with the third connecting member 3. The specific implementation method can be: the trigger part 41 can be set to a deformation part protruding toward one side of the first connecting member 1, and the first connecting member 1 has a through hole 104 corresponding to and adapted to the deformation part. When the fixing member 4 is not subjected to external force, the deformation part is embedded in the through hole 104. After the second connecting member 2 is connected to the first connecting member 1, the trigger part 41 is connected to the second connecting member 2. At this time, the second connecting member 2 supports the trigger part 41, the first locking part 42 is disconnected from the third connecting member 3, and the fixing member 4 is in the first form; when the user disassembles the second connecting member 2 and the second connecting member 2 is disconnected from the trigger part 41, that is, the external force applied to the fixing member 4 is cancelled, the deformation part is re-embedded in the through hole 104, and the fixing member 4 recovers the deformation to the second form under its own elastic action, and in this process drives the first locking part 42 to connect with the third connecting member 3.

[0050] In order to facilitate the connection or disconnection of the trigger part 41 and the second connecting member 2, refer to the attached Figure 4 and attached Figure 5 The cross-sectional shape of the trigger portion 41 can be set to a circle, and the trigger portion 41 can be set to a shape with a gradually decreasing cross-sectional size, which can reduce the resistance to connection or disconnection between the trigger portion 41 and the second connecting member 2 when the second connecting member 2 is connected to the first connecting member 1.

[0051] Specifically, in order to achieve the triggering and resetting of the trigger part 41, another implementation method is: the plug-in module provided in this embodiment also includes: a reset member, one end of the reset member is connected to the first locking part 42, and the other end is connected to the base, the reset member is an elastic structural member, which can be but is not limited to a spring or rubber structure; when the trigger part 41 is connected to the second connecting member 2, the reset member can be in an elastic compression state, and when the trigger part 41 is disconnected from the second connecting member 2, the reset member drives the first locking part 42 to connect with the third connecting member 3 under the action of its elastic force, for example: the reset member here can be but is not limited to driving the first locking part 42 by utilizing the elastic force of the reset member to restore the deformation after deformation; such a setting method can realize the selection of a variety of setting positions of the fixing member 4, and is not limited to being set at the top of the shell, making the design method more flexible.

[0052] The fixing member 4 can, but is not limited to, use one of the above two methods to achieve the triggering and automatic resetting of the triggering part 41, which is not specifically limited here.

[0054] Among them, when the number of the second connecting member 2 and / or the third connecting member 3 is more than one, in order to achieve that the second connecting member 2 or the third connecting member 3 can be locked or unlocked by the locking paddle 6, the locking paddle 6 is detachably and rotatably connected to the first fixing pin 21, and the locking paddle 6 can also be connected to the second fixing pin 32 in the same connection manner; two first fixing pins 21 and two second fixing pins 32 are respectively provided on the second connecting member 2 and the third connecting member 3, and the two first fixing pins 21 are symmetrically distributed on the end face of the second connecting member 2 away from the plug-in end, and the two second fixing pins 32 are symmetrically distributed on the end face of the third connecting member 3 away from the plug-in end.

When the second connector 2 and the corresponding first connector 1 are disconnected, the fixing member 4 is relatively fixed to the third connector 3 to lock the third connector 3 and prevent the third connector 3 from being disengaged from the corresponding first connector 3 driven by the second connector 2.
