Description

A driver board connector, a circuit board module, and a display device.

[0001] This application claims priority to Chinese Patent Application No. 202410813576.3, filed on June 21, 2024, entitled "A Driver Board Connector, Circuit Board Module and Display Device", the contents of which are to be understood as incorporated herein by reference. Technical Field

[0002] This disclosure relates to, but is not limited to, the field of display technology. More specifically, it relates to a driver board connector, a circuit board module, and a display device. Background Technology

[0003] Driver board connectors are used to enable electrical connections between rigid circuit boards (PCBs) and flexible circuit boards (FPCs) and to provide mechanical stability for electronic devices.

[0004] Based on the connection method, driver board connectors can be divided into pluggable connectors and non-locking connectors. Pluggable connectors connect rigid circuit boards (PCBs) and flexible circuit boards (FPCs) in a pluggable manner, offering advantages such as easy replacement and maintenance, but also presenting reliability issues. Non-locking connectors connect the rigid circuit board (PCB) and flexible circuit board (FPC) together through the pressure of the contact points of two terminals. Non-locking connectors utilize the friction of internal threads for locking; if the external force is too great, exceeding the friction locking limit, locking failure will occur, leading to detachment and product usage problems.

[0027] Detailed Explanation

[0028] To more clearly illustrate this application, the following description, in conjunction with embodiments and accompanying drawings, further clarifies the application. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the following description is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this application.

[0029] In related technologies, the driver board connector includes a connector A and a connector B placed in the groove of connector A. Connector B includes friction internal threads. The sidewalls of connector A and connector B are interference-fitted. The friction of the internal threads is used to lock connector A and connector B together. However, under this structural design, if the external force is too large and exceeds the friction locking limit, the locking of the driver board connector will fail, causing it to fall off and causing problems in product use.

[0030] In view of this, embodiments of this application propose a driver board connector, a circuit board module, and a display device to solve the above problems.

[0031] This application provides a driver board connector 911, as shown in FIG1. ​​The connector 911 includes a fixing member 10, a crimping member 20, and a limiting member 30, wherein...

[0032] The crimping member 20 includes:

[0033] A first docking portion 21 extending in a first direction is provided with a transmission terminal;

[0034] The extension portions 22 located at both ends of the first docking portion 21 in the first direction and extending along the first direction, each extension portion 22 located at one end includes a first sub-extension portion 221 and a second sub-extension portion 222, and the first sub-extension portion 221 and the second sub-extension portion 222 are spaced apart in a second direction that is horizontal and perpendicular to the first direction.

[0035] The fastener 10 includes:

[0036] A second docking part 11 that matches the transmission terminal of the first docking part 21; and

[0037] The receiving portion 12 located at both ends of the first docking portion 21 in the first direction includes a first cavity 121 for receiving the extension portion 22 and a second cavity 122 for receiving the limiting member 30. The second cavity 122 is farther away from the second docking portion 11 than the first cavity 121.

[0038] The limiting member 30 is movably connected to each of the extensions 22, for example, by sliding or rotating connection, and is disposed on the side of the second sub-extension 222 away from the first sub-extension 221. It is configured to move from the first cavity 121 to the second cavity 122, and the limiting member 30 is fixed in the second cavity 122 in a third direction perpendicular to the first direction and the second direction, respectively.

[0039] The driver board connector of this embodiment includes a fixing member 10, a limiting member 30, and a crimping member 20. The fixing member 10 is a base structure. The second mating part 11 of the fixing member 10 and the first mating part 21 of the crimping member 20 are matched. After the two are assembled, they can transmit signals. The crimping member 20 is disposed in the receiving part 12 of the fixing member 10. The limiting member 30 and the crimping member 20 are movably connected by the first sub-extension part 221 and the second sub-extension end of the crimping member 20. The limiting member 30 can move from the first cavity 121 of the receiving part 12 to the second cavity 122 of the receiving part 12. The limiting member 30 can lock and unlock the crimping member 20 and the fixing member 10. This arrangement can improve the limiting and locking stability of the connector in three directions and avoid the problem of frequent detachment of crimping connectors when end customers conduct whole machine drop or vibration tests in simulated consumer use.

[0040] The structure of each component of the driver board connector in the embodiments of this application will now be described by way of example.

[0041] In an optional embodiment, as shown in FIG2, the fastener 10 includes a base 13 with a groove. As shown in FIG2, the bottom surface of the base 13 is a smooth surface for easy fixing. The groove of the base 13 extends downward from the top surface of the base 13 to the bottom surface of the groove, and the depth of the groove is less than the height of the base 13.

[0042] As shown in Figure 2, the groove includes:

[0043] The groove surface 133 corresponds to the bottom surface of the groove, that is, the surface of the groove close to the bottom surface of the base 13;

[0044] The first groove wall 131, which is arranged opposite to each other and extends along the first direction; and

[0045] The second groove wall 132, which is set opposite to each other and extends along the second direction, the groove surface 133, the first groove wall 131 and the second groove wall 132 together form the groove of the base 13.

[0046] The base 13 also includes a second sidewall 134 that is disposed opposite to it and extends along the second direction, as shown in FIG2. The second sidewall 134 and the second groove wall 132 are both located on the short side of the base 13.

[0047] In this embodiment, the first cavity 121 is located at the end edge region of the groove. That is, as shown in FIG2, in the first direction, the groove region includes the first cavity 121 located on both sides and the forming region of the second docking portion 11 located in the middle. The first cavity 121 is used to place the crimping member 20 and provide the moving space for the limiting member 30. The second docking portion 11 is formed on the groove surface 133 of the groove region in the middle of the first cavities 121 on both sides, so as to perform signal transmission after being aligned with the first docking portion 21 of the crimping member 20.

[0048] In this embodiment, a hollow through-hole is provided between the second groove wall 132 and the second side wall 134 to form the second cavity 122. The second cavity 122 provides movement space for the limiting member 30, and the limiting member 30, when the second cavity 122 is limited, enables the locking and fixing of the pressing member 20 and the fixing member 10. In other words, the receiving portion 12 in this embodiment is jointly formed by the end edge region of the groove and the edge region of the base 13.

[0049] In an optional embodiment, the orthographic projection of the second cavity 122 onto the second sidewall 134 falls within the second sidewall 134. That is, the second cavity 122 extends through the surface of the second sidewall 134 as an open structure. The opening area of ​​this open structure is smaller than the area of ​​the second sidewall 134, so as to restrict the movable space of the limiting member 30 within the second cavity 122 and reduce the risk of the limiting member 30 falling off.

[0050] In an optional embodiment, as shown in FIG2,

[0051] The second docking part 11 is a protruding structure provided on the groove surface 133, which facilitates the snap-fit ​​and fixation with the first docking part 21 of the crimping member 20 to realize signal transmission.

[0052] The second docking portion 11 is projected onto the groove surface 133, and is located in the area between the two first cavities 121 at the end of the groove.

[0053] In this embodiment of the application, the second docking part 11 includes:

[0054] The second terminal sidewall 111, which is disposed opposite to each other and extends along the first direction, is provided with a plurality of second transmission terminals arranged along the first direction; and

[0055] The limiting sidewall 112, which is set opposite to each other and extends along the second direction, is configured to limit the limiting member 30. In this embodiment, the limiting sidewall 112 is one cavity boundary of the first cavity 121. That is, the second docking part 11 is divided into the setting area of ​​the transmission terminal and the moving area of ​​the limiting member 30 by the limiting sidewall 112. As shown in the schematic diagrams of Figures 1 and 2, the limiting member 30 can move in the first cavity 121. The limiting structure of the second docking part 11 limits the extreme movement position of the limiting member 30 in the first cavity.

[0056] In an optional embodiment, as shown in FIG3, the first docking portion 21 includes:

[0057] The first terminal sidewall 211, which is disposed opposite to and extends along the first direction, is provided with a first transmission terminal that matches the second transmission terminal, and

[0058] The first sidewall 212 is disposed opposite to each other and extends along the second direction, and the first sub-extension 221 and the second sub-extension 222 are respectively disposed at both ends of each first sidewall 212 in the second direction.

[0059] As shown in Figure 3, two of the four sides of the first docking part 21 are the first terminal sidewalls 211, and the first terminal sidewalls 211 are provided with first transmission terminals. The two short sides are extension parts 22. Each extension part 22 of the short side includes a first sub-extension part 221 and a second sub-extension part 222. The first sub-extension part 221 and the second sub-extension part 222 are respectively provided at both ends of each short side. There is a gap between the first sub-extension part 221 and the second sub-extension part 222 to provide the movement space required for unlocking and locking of the limiting member 30.

[0060] In this embodiment, the orthographic projections of the first sub-extension 221 and the second sub-extension 222 onto the groove surface 133 fall within the groove surface 133. That is, after the crimping member 20 and the fixing member 10 are assembled, the orthographic projection of the crimping member 20 onto the base 13 falls within the base 13. In other words, the first mating part 21 corresponds to the second mating part 11, and the extension part 22 corresponds to the first cavity 121. The entire structure of the crimping member 20 is disposed within the projection of the groove surface 133 of the fixing member 10, so as to use the first cavity 121 to protect and limit the extension parts 22 at both ends.

[0061] The method for moving the limiting member 30 of the driver board connector from the first cavity 121 to the second cavity 122 according to the embodiments of this application has different implementations. The moving method of the limiting member 30 will now be described by way of example.

[0062] In an optional embodiment, as shown in Figures 4 and 5, the limiting member 30 is configured to slide along the first direction from the first cavity 121 into the second cavity 122.

[0063] The first sub-extension 221 and the second sub-extension 222 are configured to limit the movement of the limiting member 30 in the second direction, and when the limiting member 30 moves to the end of the extension 22, the first sub-extension 221 and the second sub-extension 222 are configured to limit the sliding of the limiting member 30 in the first direction.

[0064] In an exemplary embodiment, the limiting member 30 can reciprocate along a first direction under the limiting of the first sub-extension 221 and the second sub-extension 222, while its movement distance in a second direction is limited. The limiting member 30 can slide from the first cavity 121 near the first mating portion 21 to the end of the extension 22 near the second cavity 122. When the limiting member 30 moves to the end of the extension 22, the first sub-extension 221 and the second sub-extension 222 block the movement of the limiting member 30 in the first direction, preventing the limiting member 30 from falling out of the crimping member 20.

[0065] The structure of the sliding limiting member 30 will be described below by way of example.

[0066] In an optional embodiment, as shown in Figures 4 and 5, guide rails 23 extending along the first direction are respectively provided in the sidewalls of the first sub-extension 221 and the second sub-extension 222. The length of the guide rail 23 in the first direction is less than the length of the first sub-extension 221 in the first direction. That is, the lengths in the first direction are, in order, the length of the first cavity 121 is less than the length of the guide rail 23 and less than the length of the first sub-extension 221, thereby limiting the movement distance of the limiting member 30.

[0067] The length of the guide rail 23 in the second direction is less than or equal to about 0.3 mm. The length of the guide rail 23 in the first direction is determined according to the length of the first cavity 121 of the fixing member 10 in the first direction. For example, laptop connectors and automotive connectors are relatively large in size, and the length of the guide rail 23 in the first direction can be between about 0.5 mm and 2 mm. The shape of the guide rail 23 includes, but is not limited to, rectangular grooves, circular grooves, etc., and those skilled in the art can design it according to actual applications.

[0068] In this embodiment of the application, the limiting member 30 includes:

[0069] The sliding part 31 slides on the guide rail 23, and the sliding part 31 slides on the guide rail 23 to realize the movement of the limiting member 30; and

[0070] The handheld part 32 is located on the side of the sliding part 31 away from the fixing member 10. The handheld part 32 is a protrusion extending from the fixing member 10 toward the pressing member 20. In this embodiment, the handheld part 32 is a protrusion that facilitates the user to apply external force to move and limit the movement.

[0071] In other words, the limiting member 30 in this embodiment is divided into a sliding part 31 located at the bottom and a hand-held part 32 located at the top, and the hand-held part 32 is used to drive the sliding part 31 to move.

[0072] In an optional embodiment, the maximum length of the sliding portion 31 in the second direction is greater than the interval between the first sub-extension 221 and the second sub-extension 222, and less than the distance between the guide rail 23 of the first sub-extension 221 and the guide rail 23 of the second sub-extension 222. With this arrangement, the sliding portion 31 can be confined within the guide rail 23, preventing the sliding portion 31 from dislodging from the guide rail 23.

[0073] In this embodiment of the application, the maximum length of the handheld part 32 in the second direction is less than the interval between the first sub-extension 221 and the second sub-extension 222. That is, the handheld part 32 is disposed above the sliding part 31. With the guide rail 23 in movable connection with the sliding part 31, the handheld part 32 also moves along the first direction between the interval between the first sub-extension 221 and the second sub-extension 222.

[0074] In an optional embodiment, as shown in FIG5, the limiting member 30 further includes a first limiting part 33. The first limiting part 33 is a protrusion structure disposed on the surface of the sliding part 31 or the handheld part 32 near the second cavity 122. Under the drive of the sliding part 31, the first limiting part 33 also slides along the first direction. The protrusion direction of the first limiting part 33 is the same as the protrusion direction of the first sub-extension 221. When the sliding part 31 slides to the end of the first sub-extension 221, the protrusion structure of the first limiting part 33 is inserted into the second cavity 122. With the cooperation of the first limiting part 33 and the fixing member 10, the protrusion structure inserted into the second cavity 122 is limited in both the first direction and the second direction.

[0075] In this embodiment, the thickness of the protrusion structure of the first limiting part 33 in the third direction is less than that of the second cavity 122, thereby ensuring that the protrusion structure of the first limiting part 33 can be easily inserted into the second cavity 122 of the fixing member 10, thus improving the locking efficiency.

[0076] For example, the length of the protrusion structure of the first limiting part 33 in the second direction is greater than or equal to about 0.5 mm. The orthographic projection of the first limiting part 33 on the base 13 includes, but is not limited to, shapes such as cuboids, ellipses, trapezoids or even irregular shapes that can play a limiting role. Those skilled in the art will not elaborate further here.

[0077] In an optional embodiment, as shown in Figures 4 and 5, the length of the sliding part 31 along the second direction is less than the length of the first limiting part 33 along the second direction. With this setting, the sliding part 31 can move in the guide rail 23, and ensures that when the first limiting part 33 is inserted into the second cavity 122, the sliding part 31 will not move into the second cavity 122, thus realizing the partition design of the two parts of the first limiting part 33 with different functions.

[0078] In an optional embodiment, as shown in Figures 4 and 5, the limiting member 30 further includes a second limiting portion 34 disposed on the surface of the handheld portion 32 near the second cavity 122, the length of the second limiting portion 34 being variable in the second direction.

[0079] When the sliding part 31 is located in the interval between the first sub-extension 221 and the second sub-extension 222, the length of the second limiting part 34 in the second direction is the first length.

[0080] When the sliding part 31 is located at the end position of the first sub-extension 221 and the second sub-extension 222, the length of the second limiting part 34 in the second direction is the second length, and the first length is less than the second length.

[0081] In other words, the variable length of the second limiting part 34 of the limiting member 30 in this application embodiment means that the length of the second limiting part 34 along the second direction is different at different positions, and the second limiting part 34 is used for unlocking and locking by means of this setting.

[0082] In an optional embodiment, the maximum length of the second limiting portion 34 along the second direction is greater than the maximum distance between the opposing sidewalls of the first sub-extension 221 and the second sub-extension 222, ensuring the limiting effect of the second limiting portion 34 when sliding to the end of the first sub-extension 221.

[0083] The second limiting part 34 includes a pressing part 341 and a deformable part 342. The pressing part 341 is located at both ends of the deformable part 342. When the second limiting part 34 is located in the first cavity 121 under the drive of the guide rail 23, the pressing part 341 is restricted in the interval between the first sub-extension 221 and the second sub-extension 222 under the elastic action of the deformable part 342. When the second limiting part 34 slides to the end of the first sub-extension 221, the pressing part 341 is driven to the first sub-extension 221 and the second sub-extension 222 under the elastic action of the deformable part 342, thereby realizing the limiting of the limiting member 30 in the first direction.

[0084] In this embodiment, the length of the extrusion part 341 in the first and second directions can be determined according to the redundant space of the drive board connector. The length of the extrusion part 341 in the first and second directions is approximately 0.1mm-1mm. Its shape includes, but is not limited to, a strip, a sphere, or an irregular shape that can be positioned. Those skilled in the art can design it according to the actual application.

[0085] For example, the deformable portion 342 may be a plurality of springs arranged along a third direction, the springs including but not limited to helical structures. For example, the spacing between adjacent springs is about 0.2 mm or more, the number of springs is generally between 2 and 8, and the length of each spring in the second direction ranges from about 0.2 mm to 0.8 mm. Those skilled in the art can design it according to actual applications.

[0086] In an optional embodiment, as shown in FIG5, when the sliding part 31 is located at the end position of the first sub-extension 221 and the second sub-extension 222, the second limiting part 34 is located outside the first sub-extension 221 and the second sub-extension 222. The second limiting part 34 abuts against and limits the surface of the first sub-extension 221 and the end surface of the first sub-extension 221, and abuts against and limits the surface of the second sub-extension 222 and the end surface of the second sub-extension 222. With this arrangement, when the sliding part 31 is located at the end, the second limiting part 34 forms a limit with the end of the first sub-extension and the end of the second sub-extension.

[0087] In an optional embodiment, as shown in FIG4, the crimping member 20 further includes a connecting portion 223 connecting the first sub-extension 221 and the second sub-extension 222. The end surface of the first sub-extension 221 is perpendicular to the surface of the connecting portion 223 away from the fixing member 10, and the end surface of the second sub-extension 222 is perpendicular to the surface of the connecting portion 223 away from the fixing member 10. On the one hand, the embodiment of this application uses the connecting portion 223 to connect the first sub-extension 221 and the second sub-extension 222, which can improve the overall strength of the crimping member 20. On the other hand, the connecting portion 223 extends along the second direction to limit the limiting member 30 that moves along the first direction, thus preventing it from falling off.

[0088] In this embodiment of the application, as shown in FIG4, a hollow cavity 224 is located at the interval between the first sub-extension 221 and the second sub-extension 222 to provide a moving space for the limiting member 30. The connecting part 223 includes a snap-fit ​​part 2231 located at the interval between the first sub-extension 221 and the second sub-extension 222 and fixed to the limiting member 30, and a fixed platform part 2232 connected to the first sub-extension 221 and the second sub-extension 222 respectively. The snap-fit ​​part 2231 is used to fix to the limiting member 30, and the platform part 2232 is used to form an extension platform with the first sub-extension 221 and the second sub-extension 222. The extension platform is used to form a bearing for the end of the second limiting part 34. In an optional embodiment, as shown in FIG4 and FIG5, the distance between the surface of the platform part 2232 away from the fixing member 10 and the fixing member 10 is smaller than the distance between the surface of the first sub-extension 221 away from the fixing member 10 and the fixing member 10. That is, the platform portion 2232 and the first sub-extension portion 221 form a stepped structure. When the second limiting portion 34 moves from the interval position between the first sub-extension portion 221 and the second sub-extension portion 222 to the end position of the first sub-extension portion 221 and the second sub-extension portion 222, the end of the second limiting portion 34 abuts against the first sub-extension portion 221 and the second sub-extension portion 222, and the end of the second limiting portion 34 bears the load of the platform portion 2232.

[0089] In an optional embodiment, as shown in Figures 4 and 5, limiting grooves 2231 are respectively formed on the surface of the connecting portion 223 away from the fixing member 10 at the edge positions near the end surfaces of the first sub-extension 221 and the second sub-extension 222, configured to limit the second limiting portion 34 in the second direction.

[0090] In an exemplary embodiment, as shown in Figures 4 and 5, limiting grooves 2231 are respectively disposed on the platform surface of the platform portion 2232 near the first sub-extension portion 221 and near the second sub-extension portion 222. When the second limiting portion 34 moves along the first direction to the end of the first sub-extension portion 221 and the second sub-extension portion 222, the second limiting portion 34 is fixed in the limiting groove 2231, thereby limiting the second limiting portion 34 in the first direction and the second direction.

[0091] In an exemplary embodiment, the limiting groove 2231 is configured to cooperate with the extrusion part 341, and its length dimension in the first direction and the second direction is approximately 0.1mm-1mm. The shape includes, but is not limited to, rectangular grooves, circular grooves, etc. Those skilled in the art can design according to practical applications.

[0092] In an optional embodiment, the limiting member 30 includes a shielding member (not shown in the figure) that shields the surface of the second limiting part 34 away from the fixing member 10 and the surface away from the handheld part 32. The shielding member is used to shield the second limiting part 34 to prevent dust from affecting the limiting and fixing of the second limiting part 34.

[0093] For example, the blocking component is generally about 0.2mm higher than the spring to ensure the blocking effect while avoiding interference with the second limiting part 34.

[0094] In one exemplary embodiment, the latching process of the driver board connector is as follows:

[0095] In this embodiment, the limiting member 30 and the fixing member 10 are pre-assembled. The sliding part 31 of the limiting member 30 is installed on the guide rail 23 provided in the first sub-extension 221 and the second sub-extension 222 of the fixing member 10. The first limiting part 33 faces the second cavity 122.

[0096] Before the fixing member 10 and the limiting member 30 are pressed together, the first mating part 21 of the pressing member 20 and the second mating part 11 of the fixing member 10 are aligned. The first limiting part 33 of the limiting member 30 is located in the interval between the first sub-extension 221 and the second sub-extension 222, and is at the first length. The first limiting part 33 forms an interactive frictional force with the sidewalls of the first sub-extension 221 and the second sub-extension 222 respectively, to prevent the sliding part 31 of the limiting member 30 from sliding on the guide rail 23, so as to facilitate the pressing member 20 to be embedded and pressed into the fixing member 10.

[0097] Then, the fixing member 10 and the limiting member 30 are crimped together. The transmission terminals of the first mating part 21 of the crimping member 20 and the second mating part 11 of the fixing member 10 are aligned and matched. The extension part 22 of the crimping member 20 is embedded into the first cavity 121 of the receiving part 12 of the fixing member 10. At this time, the orthographic projection of the limiting member 30 on the groove surface 133 falls completely within the orthographic projection of the first cavity 121 on the groove surface 133. That is, the limiting member 30 is entirely placed in the first cavity 121 and does not move to the second cavity 122. In other words, the end of the first limiting part 33 of the limiting member 30 near the second cavity 122 is located in the first cavity 121, so as to avoid interference between the limiting member 30 and the fixing member 10 during the crimping process of the fixing member 10 and the limiting member 30.

[0098] After the fixing member 10 and the limiting member 30 are pressed together, the fixing member 10 and the pressing member 20 are locked together by the limiting member 30. The second limiting part 34 is squeezed so that the length of the second limiting part 34 in the second direction is less than the first length. By controlling the hand-held part 32, the sliding part 31 moves along the guide rail 23 in the first direction. The first limiting part 33 is inserted from the first cavity 121 into the second cavity 122. At this time, the second cavity 122 limits the first limiting part 33 in the second direction and the third direction to prevent the fixing member 10 and the pressing member 20 from falling off along the pressing direction.

[0099] On the other hand, when the limiting member 30 moves along the first direction to the ends of the first sub-extension 221 and the second sub-extension 222, the length of the second limiting member 34 becomes the second length. Under the action of tension, the second limiting member 34 is inserted into the limiting groove 2231, thereby limiting the limiting member 30 in the first direction and the second direction. A fixation is formed between the limiting member 30, the fixing member 10 and the pressing member 20, and the locking of the fixing member 10 and the pressing member 20 is completed.

[0100] In one exemplary embodiment, the unlocking process of the driver board connector in this application is as follows:

[0101] After pressing the second limiting part 34, the second length of the second limiting part 34 will become less than or equal to the first length. Control the hand-held part 32 to drive the sliding part 31 to move in the first direction, so that the second limiting part 34 moves from the second cavity 122 to the first cavity 121. Then remove the crimping member 20 to complete the unlocking between the limiting member 30, the fixing member 10 and the crimping member 20.

[0102] As shown in Figures 6-8, in one illustrative embodiment, another movement mode of the limiting member 30 is proposed. Unlike the movement mode of the limiting member 30 shown in Figures 1-5, where the limiting member 30 slides from the first cavity 121 to the second cavity 122, in this embodiment, the limiting member 30 rotates from the first cavity 121 to the second cavity 122. This embodiment will now be described.

[0103] In an optional embodiment, the first sub-extension 221 and the second sub-extension 222 are configured to limit the movement of the limiting member 30 in the third direction. The limiting member 30 is configured to rotate from the first cavity 121 to the second cavity 122 on a horizontal plane formed by the first direction and the second direction, with an axis parallel to the third direction as the axis of rotation.

[0104] In an optional embodiment, as shown in FIG3,

[0105] The first sub-extension 221 has a third cavity (covered in Figure 3, and disposed opposite to the fourth cavity 2220). The third cavity extends from the surface of the first sub-extension 221 near the second sub-extension 222 along a second direction. For example, the third cavity is the cavity originally used to accommodate the guide rail. In this example, the first sub-extension 221 does not have a guide rail, but still has a third cavity to accommodate the driven blocking member.

[0106] The second sub-extension 222 has a fourth cavity 2220. The fourth cavity 2220 extends from the surface of the second sub-extension 222 near the second sub-extension 222 along a second direction. For example, the fourth cavity 2220 is originally used to accommodate the guide rail. In this example, the second sub-extension 222 does not have a guide rail, but it still has a fourth cavity 2220 to accommodate the driven blocking member.

[0107] In this embodiment, the orthographic projection of the third cavity onto the base 13 falls within the orthographic projection of the first cavity 121 onto the base 13, and the orthographic projection of the fourth cavity 2220 onto the base 13 falls within the orthographic projection of the first cavity 121 onto the base 13. The third cavity, the fourth cavity 2220, and the first cavity 121 all provide accommodating space for the limiting member 30, preventing interference between the limiting member 30 and the fixing member 10 and the pressing member 20 at the corresponding positions of the second cavity 122 during the pressing process of the fixing member 10 and the pressing member 20.

[0108] In an optional embodiment, FIG8 shows a schematic diagram of the limiting member from the AA viewpoint in FIG7. As shown in FIG8, the limiting member 30 includes:

[0109] A rotating member 41 is vertically arranged along a third direction. The rotating member 41 rotates about a central axis parallel to the third direction. The rotating member 41 passes through the surface of the first sub-extension 221 away from the fixing member 10 and extends to the third cavity. The rotating member 41 also passes through the surface of the second sub-extension 222 away from the fixing member 10 and extends to the fourth cavity 2220.

[0110] The active member 42 of the rotating member 41 is ringed, the active member 42 is located on the surface of the first sub-extension 221 away from the fixing member 10, and on the surface of the second sub-extension 222 away from the fixing member 10;

[0111] The driven blocking member 43 of the rotating member 41 is ring-shaped, and the driven blocking member 43 is located in the third cavity and the fourth cavity 2220 respectively.

[0112] The active member 42 uses the rotating member 41 to drive the driven blocking member 43 to rotate from the first cavity 121 to the second cavity 122.

[0113] The limiting member 30 in this embodiment is a rotating structure. Figure 6 shows a schematic diagram of the position of the limiting member 30 before the fixing member 10 and the pressing member 20 are locked. As shown in Figure 6, before the fixing member 10 and the pressing member 20 are pressed together, the driving member 42 drives the rotating member 41 to realize the rotation function of the driven blocking member 43, so that the driven blocking member 43 is respectively set in the third cavity and the fourth cavity 2220. The driven blocking member 43 extends from the third cavity or the fourth cavity 2220 to the position of the corresponding first cavity 121, so as to avoid interference between the limiting member 30 and the fixing member 10 and the pressing member 20 at the corresponding position of the second cavity 122 during the pressing process of the fixing member 10 and the pressing member 20.

[0114] Figure 7 shows a schematic diagram of the position of the limiting member 30 after the fixing member 10 and the pressing member 20 are locked together. As shown in Figure 7, after the driving member 42 rotates a certain angle, it is driven by the rotating member 41. The driven blocking member 43 is also rotated a certain angle from the first cavity 121 to the second cavity 122. After the driven blocking member 43 rotates to the second cavity 122, the fixing member 10 limits it, so that the driven blocking member 43 cannot move in the pressing direction (third direction), thereby realizing the locking of the fixing member 10 and the pressing member 20.

[0115] In an optional embodiment, the driven blocking member 43 and the second cavity 122 are interference fits, and the driven blocking member 43, the third cavity, and the fourth cavity 2220 are clearance fits. This arrangement allows the driven blocking member 43 to rotate flexibly within the first cavity 121, the third cavity, and the fourth cavity 2220 during the locking process, while making it difficult for the driven blocking member 43 to fall off the second cavity 122 after locking, thus improving the locking stability.

[0116] In an optional embodiment, the minimum distance between the end of the driven blocking member 43 and the axis of the rotating member 41 is greater than the minimum distance between the axis of the rotating member 41 and the cavity edge of the second cavity 122 near the first cavity 121, thereby reducing the risk of the driven blocking member 43 falling off after rotating into the second cavity 122.

[0117] For example, the distance between the end of the driven blocking member 43 and the axis of the rotating member 41, i.e., the length of the driven blocking member 43, is about 1mm-10mm. The distance between the end of the driving member 42 and the axis of the rotating member 41, i.e., the length of the driving member 42, is about 0.5mm-10mm. The structures of the driving member 42 and the driven blocking member 43 include, but are not limited to, long strips, cylinders, etc., and those skilled in the art do not limit them.

[0118] The driver board connector based on each of the above embodiments has stable locking performance, which can improve the problem of frequent detachment of crimp connectors when end customers conduct whole-machine drop or vibration tests simulating consumer use.
