Description

Car roller blinds Technical Field

[0001] This utility model relates to the field of automotive interior decoration technology, and in particular to a vehicle roller blind. Background Technology

[0002] With the development of the automotive industry, people's requirements for car interiors are also increasing, leading to many modifications to car headliners. As shown in Figure 1, a flexible circuit structure is installed inside the roller blind to meet various functions, such as creating a starry sky effect, offering a variety of colors, and enhancing the overall sense of space and texture.

[0003] However, to ensure the transmission of current and signals in the flexible circuit structure, the curtain usually does not support a rewind function. This is because the wiring harness and power supply are fixed, while the curtain that supports a rewind function is a moving part, making it difficult to transmit power and signals to the moving part through fixed components. Therefore, although the flexible circuit structure can enrich the decorative effect of the curtain, for ceilings with skylights, the inability to rewind the curtain will hinder the use of the skylight. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides a vehicle roller blind. Through the coordinated arrangement of the male and female head assemblies, it enables power supply and signal transmission to the flexible circuit structure when the curtain is not unfolded, thus balancing the curtain's rolling and unfolding functions with rich display effects.

[0005] This utility model is achieved through the following solution: a vehicle roller blind, comprising:

[0006] The frame assembly can be installed on the car roof;

[0007] A curtain assembly includes a curtain and a roller, wherein the curtain has a built-in flexible circuit structure and the roller is rotatably connected to one end of the frame assembly to wind up and unwind the curtain;

[0008] The docking assembly includes a female connector assembly and a male connector assembly. One of the female connector assembly and the male connector assembly is mounted on the frame assembly at the other end opposite to the drum and is electrically connected to the controller assembly. The other of the female connector assembly and the male connector assembly is mounted on the curtain and is electrically connected to the flexible circuit structure. When the curtain is in the unfolded state, the male connector assembly contacts the female connector assembly to achieve electrical connection, and when the curtain is in the retracted state, the electrical connection with the female connector assembly is disconnected.

[0009] A further improvement of this utility model is that: the female connector assembly includes a female connector bracket and a female connector wire harness laid on the female connector bracket; the male connector assembly includes a male connector bracket and a male connector wire harness laid on the male connector bracket; the female connector assembly is provided with a socket, and the male connector assembly is provided with a plug; when the curtain is in the unfolded state, the plug is inserted into the socket, and the first end of the female connector wire harness and the first end of the male connector wire harness are in corresponding contact to achieve electrical connection; when the curtain is in the retracted state, the plug is disengaged from the socket, and the first end of the female connector wire harness and the first end of the male connector wire harness are disconnected from the electrical connection.

[0010] A further improvement of this utility model is that the female head assembly further includes a female head body, which is movably connected to the female head bracket.

[0011] A further improvement of this utility model is that the female head body is movably connected to the female head support through a first elastic element.

[0012] A further improvement of this utility model is that: the female head assembly further includes a female head base for accommodating and fixing the female head body, the first elastic element is disposed between the female head base and the female head support, and the female head body is movably connected to the female head support through the female head base and the first elastic element.

[0013] A further improvement of this utility model is that the docking assembly further includes a magnetic sheet disposed on the female head body and / or the plug.

[0014] A further improvement of this utility model is that the magnetic sheet includes a first magnetic sheet fixed to the female head body and a second magnetic sheet fixed to the plug for magnetic attraction by the first magnetic sheet.

[0015] A further improvement of this utility model is that: the male connector assembly further includes a male connector body forming the plug, the male connector body being movably connected to the male connector bracket; the male connector harness is laid on the male connector body.

[0016] A further improvement of this utility model is that the male connector assembly further includes a male connector base for fixing the male connector body, and a second elastic member disposed between the male connector base and the male connector bracket, wherein the male connector body is movably connected to the male connector bracket through the second elastic member.

[0017] A further improvement of this utility model is that the male connector assembly further includes a guide pin disposed on the male connector base, and the female connector assembly further includes a pin hole for the guide pin to be inserted. Both the guide pin and the pin hole extend along the plug insertion direction, and the top end of the guide pin extends beyond the plug and is formed into a cone.

[0018] A further improvement of this utility model is that the second elastic element includes a spring extending along the plug insertion direction, and one end of the spring is fixedly connected to the male base and the other end is fixedly connected to the male bracket.

[0019] This invention, through the cooperative arrangement of the female and male connector assemblies, enables automatic contact and energization when the curtain is fully extended, thereby facilitating the transmission of current and signals to the flexible circuit structure built into the curtain. Conversely, when the curtain is rolled up, the two automatically separate to disconnect the transmission of current and signals. This design balances the curtain's rolling and unfolding functions with rich display effects, meeting the needs of skylight users. Furthermore, a structure is provided between the female and male connector assemblies to eliminate tolerances during connection, ensuring reliable contact. Attached Figure Description

[0048] To address the problem that existing automotive curtains with flexible circuit structures cannot be rolled up, thus hindering sunroof use, this invention provides an automotive roller blind that enables power supply and signal transmission to the flexible circuit structure when the curtain is unfolded. This achieves both the rolling up and unfolding functions of the curtain, as well as rich display effects. The following detailed description, in conjunction with the accompanying drawings, further illustrates this automotive roller blind with specific embodiments.

[0049] Referring to Figures 1-9 and 23-24, a vehicle roller blind includes a frame assembly 2, a curtain assembly 3, a drive assembly 4, and a docking assembly. The frame assembly 2 is a rectangular frame structure, including a front beam 21 at the front end, a rear beam 22 at the rear end, and two side beams 23 connecting the two ends of the front beam 21 and the rear beam 22. The frame assembly 2 is mounted on the vehicle roof 1 and corresponds to the sunroof on the vehicle roof 1. Specifically, the frame assembly 2 can be fixedly installed on the inside of the vehicle roof 1, or detachably assembled to the inside of the vehicle roof 1. In the assembled state, the front beam 21 is located at the front end in the vehicle's forward direction, and the rear beam 22 is located at the rear end in the vehicle's forward direction. The curtain assembly 3 includes a curtain 31 and a roller 32. The curtain 31 has a built-in flexible circuit structure 33 for enriching display functions. A common feature is that it can display a starry sky effect when powered on. The roller 32 is rotatably connected to one end of the frame assembly 2 (such as the rear beam 22 or the front beam 21) to roll up and unroll the curtain 31. When energized, the flexible circuit structure 33 can make the curtain 31 display visual effects such as a starry sky.

[0050] The rolling and unfolding of the curtain 31 is controlled by the drive assembly 4. In some embodiments, the drive assembly 4 is mounted on the frame assembly 2 (such as the rear beam 22 or the front beam 21), and the drive assembly 4 drives the curtain 31 to achieve the rolling and unfolding of the curtain. When the curtain 31 is in the unfolded state, it can cover the sunroof installed on the car roof 1, so that the area below the sunroof can display a starry sky or other display effects. When the curtain 31 is in the rolled-up state, the frame assembly 2 is opened, and the sunroof at the car roof 1 can be exposed.

[0051] The docking assembly includes a female connector assembly 51 mounted on the frame assembly 2 at the other end opposite the roller 32 and electrically connected to the controller assembly 7, and a male connector assembly 52 mounted on the curtain 31 and electrically connected to the flexible circuit structure 33. It should be noted that the positions of the female connector assembly 51 and the male connector assembly 52 are interchangeable; that is, the female connector assembly 51 is mounted on the curtain 31 and electrically connected to the flexible circuit structure 33, while the male connector assembly 52 is mounted on the frame assembly 2 at the other end opposite the roller 32 and electrically connected to the controller assembly 7. When the curtain 31 is in the unfolded state (as shown in Figure 9), the male connector assembly 52 contacts the female connector assembly 51 to achieve electrical connection, transmitting the received current and signals to the chip 331 of the flexible circuit structure 33 to realize the display of starry sky effects on the curtain 31. When starry sky effects are not required, the curtain 31 is rolled up. When the curtain 31 is in the rolled-up state (as shown in Figure 2), the male connector assembly 52 is electrically disconnected from the female connector assembly 51. The controller assembly 7 includes a first control module 71 for controlling the chip 331 of the flexible circuit structure 33 and a second control module 72 for controlling the drive assembly 4 (as shown in Figure 8). The first control module 71 and the second control module 72 can be integrated together and mounted on the frame assembly 2 via a fourth mounting pin 84. For ease of installation of the roller 32, the controller assembly 7 is preferably mounted at the opposite end of the roller 32. Furthermore, for ease of control of the drive assembly 4, the drive assembly 4 is also mounted at the opposite end of the roller 32. Correspondingly, for ease of driving the curtain 31, a flexible rod 41 is connected to the drive assembly 4. The flexible rod 41 is connected to the curtain 31, and by driving the flexible rod 41 to push and pull the curtain 31, the curtain can be rolled up and unrolled. Specifically, the current and signals transmitted by the controller assembly 7 can be provided by the vehicle's signal and power supply. The first control module 71 is connected to the female connector assembly 51 or the male connector assembly 52 to transmit current and signals to either assembly. The female connector assembly 51 and the male connector assembly 52, through contact with each other, transmit the received current and signals to the chip 331 of the flexible circuit structure 33 to achieve the starry sky effect display of the curtain 31. The second control module 72 is connected to the drive assembly 4 to transmit control signals provided by the vehicle to the drive assembly 4. After receiving the control signals, the drive assembly 4 drives the flexible lead screw 41 to achieve the winding and unfolding of the curtain 31. The specific principle is shown in Figure 4.

[0052] This invention, through the cooperative arrangement of the female connector assembly 51 and the male connector assembly 52, enables automatic contact and energization between the two when the curtain 31 is fully extended, thereby allowing the transmission of current and signals to the flexible circuit structure 33. Conversely, when the curtain 31 is rolled up, the two automatically separate to disconnect the transmission of current and signals. This design balances the functions of curtain roll-up and roll-up with rich display effects, meeting the usage requirements of skylights.

[0053] Regarding the winding of the curtain fabric 31, referring to Figures 5-10 and Figure 25, the curtain fabric 31 includes a fixed end fixed to the roller 32 and a moving end opposite the fixed end. The male connector assembly 52 or the female connector assembly 51 is installed on the moving end of the curtain fabric 31. Because the chip 331 cannot be wound or bent, and to facilitate the docking of the female connector assembly 51 and the male connector assembly 52, the chip 331 is also located on the moving end of the curtain fabric 31, directly opposite the male connector assembly 52 or the female connector assembly 51. It should be noted that for large-sized curtain fabric 31, the built-in flexible circuit structure 33 may be composed of two or more pieces spliced ​​together. For such splicing structures, splicing can only be carried out along the width direction of the vehicle, and each splicing piece should be laid continuously between the first and last ends, with the corresponding chip 331 all located at the moving end of the curtain fabric 31. In addition, the moving end of the curtain fabric 31 is fixedly connected to the flexible lead rod 41 for traction by the flexible lead rod 41. Regarding the installation of the roller 32, taking the rear beam 22 fixed at its tail end as an example, a fixed shaft 25 is fixed along the entire length of the rear beam 22. The roller 32 is rotatably sleeved on the fixed shaft 25. Both ends of the rear beam 22 are fixedly connected to a shaft-side bracket 24 by a third mounting nail 83. The shaft-side bracket 24 is provided with an internal insert 241. Both ends of the fixed shaft 25 pass through the roller 32 and are fixedly connected to the two internal inserts 241, as shown in Figure 10. The roller 32 is covered with a chip bracket for securing the fixed end of the curtain 31 to the roller 32. The chip bracket includes an upper chip bracket 34 with a strip-shaped opening 341 and a lower chip bracket 35 detachably connected to the upper chip bracket 34.

[0054] When installing the curtain 31, first, the roller 32 is fitted inside the chip upper bracket 34, and the fixed end of the curtain 31 is placed inside the chip upper bracket 34. Then, the rest of the curtain 31, except for the fixed end, is passed through the slot 341 and wrapped around the chip upper bracket 34. The chip lower bracket 35 is pressed onto the curtain 31 wrapped around the chip upper bracket 34 and fixed to the chip upper bracket 34 by the first mounting pin 81. At the same time, the moving end of the curtain 31 extends out through the seam between the chip upper bracket 34 and the chip lower bracket 35. Then, the entire roller 32 with the curtain 31 wrapped around it is fitted outside the fixed shaft 25 and fixed to the fixed shaft 25 by the two shaft-side brackets 24. After the curtain 31 is installed, the extended moving end is fixed to the installed flexible lead screw 41.

[0055] Regarding the driving of the curtain fabric 31 by the drive assembly 4, referring to Figures 23-27, the flexible lead screw 41 is a toothed flexible shaft. The drive assembly 4 includes a motor 42 mounted on the frame assembly 2 and a gear 43 fixedly connected to the output shaft of the motor 42. There are two flexible lead screws 41, and the first ends of the two flexible lead screws 41 are meshed parallel to each other with the teeth on opposite sides of the gear 43. The second ends of the two flexible lead screws 41 are respectively formed with flexible shaft rubber coatings 411, and are connected to both sides of the moving end of the curtain fabric 31 through the flexible shaft rubber coatings 411. Slide rails are formed on both sides of the frame assembly 2, and the two flexible shaft rubber coatings 411 are slidably engaged with the two slide rails respectively. Specifically, the two side rails are zigzag grooves, formed on the inner sides of the two side beams 23 respectively. The outer sides of the two flexible shaft rubber-coated 411 form zigzag protrusions adapted to the groove structure. Through the cooperation of the zigzag grooves and protrusions, the flexible shaft rubber-coated 411 can only slide along the extension direction of the rail, and will not deviate in the direction perpendicular to the rail. The inner sides of the two flexible shaft rubber-coated 411 are fixedly connected to both sides of the moving end of the curtain 31, so that the curtain 31 can be smoothly pulled. To facilitate the fixed connection of the two flexible shaft rubber-coated 411 to the moving end, as shown in Figure 7, a pull plate 312 is connected to the moving end. The two flexible shaft rubber-coated 411 are fixed to both ends of the pull plate 312. A steel wire 311 is sewn inside the moving end, and is fixed to the two flexible shaft rubber-coated 411 through the steel wire 311, thus achieving the fixation of the moving end to the two flexible shaft rubber-coated 411. Preferably, as shown in Figures 24 and 26, the drive assembly 4 is fixed with limiting pads 44 at positions corresponding to the opposite sides of the gear 43, for engaging the gear 43 and clamping it outside the corresponding lead screw 41 to prevent the lead screw 41 from disengaging from the gear 43. The limiting pads 44 are preferably made of wear-resistant sheets.

[0056] The driving principle of the drive assembly 4 is illustrated by an example where the drum 32 is mounted on the rear beam 22 at the rear end and the drive assembly 4 is mounted on the front beam 21 at the front end: Regarding the unfolding of the curtain 31, the motor 42 drives the gear 43 to rotate, which in turn causes the first ends of the two flexible lead screws 41 to move relative to each other. This causes the two rubber-coated flexible shafts 411 to move synchronously along the forward direction of the vehicle (i.e., the direction indicated by the arrow in Figure 23), thereby driving the moving end of the curtain 31 from the rear end to the front end, thus unfolding the curtain 31. The fully unfolded state is shown in Figure 9. Regarding the winding of the curtain 31, the motor 42 drives the gear 43 to rotate in the opposite direction, which in turn causes the first ends of the two flexible lead screws 41 to move in the opposite direction. This causes the two rubber-coated flexible shafts 411 to move synchronously along the reverse direction of the vehicle, thereby pushing the moving end of the curtain 31 from the front end to the rear end, thus winding the curtain 31. However, it should be noted that since the flexible lead screw 41 is a flexible shaft, in order to prevent the flexible shaft from bending and deforming when pushing the curtain 31, in this embodiment, referring to Figures 9 to 11, the roller blind also includes a third elastic element 6, which is installed between the frame assembly 2 and the roller 32. The third elastic element 6 applies a restoring force to the roller 32, and in the reset state, the curtain 31 returns from the unfolded state to the rolled-up state. In other words, when the drive assembly 4 drives the curtain 31 to roll up, the third elastic element 6 can provide a reverse force to the roller 32, thereby causing the curtain 31 to pull the two flexible shaft coatings 411 in the opposite direction, so that the two flexible lead screws 41 can remain in a taut state and prevent them from bending and deforming. Regarding the third elastic element 6, in this embodiment, the third elastic element 6 is a torsion spring, which is sleeved between the drum 32 and the fixed shaft 25, and one end of the third elastic element 6 is fixedly connected to the fixed shaft 25 and the other end is fixedly connected to the drum 32.

[0057] Referring to Figures 18 and 21, the female connector assembly 51 includes a female connector bracket 512 and a female connector harness 511 laid on the female connector bracket 512. The male connector assembly 52 includes a male connector bracket 522 and a male connector harness 521 laid on the male connector bracket 522. The second end of the female connector harness 511 is electrically connected to the controller assembly 7 or the flexible circuit structure 33 to achieve electrical connection between the female connector assembly 51 and the controller assembly 7 or the flexible circuit structure 33. Similarly, the second end of the male connector harness 521 is electrically connected to the flexible circuit structure 33 or the controller assembly 7 to achieve electrical connection between the male connector assembly 52 and the flexible circuit structure 33 or the controller assembly 7. The female connector assembly 51 is provided with a socket, and the male connector assembly 52 is provided with a plug. When the curtain 31 is in the unfolded state, the plug is inserted into the socket, and the first end of the female connector 511 and the first end of the male connector 521 make corresponding contact to achieve electrical connection. When the curtain 31 is in the retracted state, the plug is disengaged from the socket, and the first end of the female connector 511 and the first end of the male connector 521 are disconnected from the electrical connection. Regarding the mating of the socket and plug, and the contact and disconnection of the first ends of the female connector 511 and the male connector 521, a pin-to-pin connection can be used, or a magnetic assembly can be used where the socket or plug is magnetic and the plug or socket is metal.

[0058] In some embodiments, referring to Figures 12 and 18, the female connector assembly 51 further includes a female connector body 513, on which the female connector harness 511 is laid. The female connector body 513 is movably connected to the female connector bracket 512. Through the movable connection between the female connector body 513 and the female connector bracket 512, tolerances between the male connector assembly 52 and the female connector assembly 51 can be absorbed when the male connector assembly 52 is inserted into the female connector assembly 51. These tolerances mainly include tolerances along the insertion direction and tolerances perpendicular to the insertion direction. The movable connection between the female connector body 513 and the female connector bracket 512 can be achieved using a first elastic member 515. The elastic deformation of the first elastic member 515 can be achieved through the elasticity of the material itself or through compression deformation. The following two embodiments will illustrate this further:

[0059] In the first embodiment, referring to Figures 12 and 16-18, the male connector assembly 52 further includes a male connector body 523 forming a plug. The male connector body 523 is movably connected to the male connector bracket 522, and the male connector wire harness 521 is laid on the male connector body 523. A socket for plug insertion is formed on the female connector bracket 512. The first elastic member 515 achieves elastic deformation through compression deformation. Specifically, the first elastic member 515 includes at least one spring. In this embodiment, the first elastic member 515 includes three springs, one of which extends along the direction of plug insertion into the socket (i.e., the direction of the arrow in the figure), and the other two extend along the direction perpendicular to the plug insertion into the socket. Through the combined action of the three springs, the tolerance between the two (including the tolerance along the insertion direction and the tolerance along the direction perpendicular to the insertion direction) can be absorbed when the plug is inserted into the socket. Preferably, the inner periphery of the socket is formed as an inner slope 517 that gradually slopes inward along the insertion direction, while the outer periphery of the plug is formed as an outer slope 526 that gradually slopes inward along the insertion direction. The cooperation of the inner slope 517 and the outer slope 526 provides insertion guidance, allowing the plug to be inserted more accurately into the socket. Preferably, the inclination angle of the outer slope 526 is greater than that of the inner slope 517 to further improve the insertion guidance effect. Preferably, to further absorb the tolerance between the two when the plug is inserted into the socket, a first magnetic piece 5131 is provided on the side of the female connector body 513 facing the plug, and a second magnetic piece 5231 is provided on the side of the male connector body 523 facing the socket for the first magnetic piece 5131 to be attracted. Preferably, the first magnetic pieces 5131 are arranged in pairs and symmetrically on the outer periphery of the female connector body 513, and the number of second magnetic pieces 5231 is the same as the number of first magnetic pieces 5131, with their positions directly opposite each other. By using the first magnetic piece 541 and the second magnetic piece 542 in combination, the tolerance between them can be absorbed when the plug is inserted into the socket. It should be noted that one of the first magnetic piece 5131 and the second magnetic piece 5231 can be replaced with a metal part, and the combination of a metal part and a magnetic piece can also achieve a magnetic attraction effect.

[0060] The second embodiment, as shown in Figures 13-18, differs from the first embodiment in the structure of the female connector assembly 51 and the elastic deformation principle of the first elastic element 515. Specifically, the female connector assembly 51 further includes a female connector base 514 that accommodates and fixes the female connector body 513, and the first elastic element 515 is disposed between the female connector base 514 and the female connector support 512. The female connector body 513, female connector base 514, first elastic element 515, and female connector support 512 are all frame-shaped structures, sequentially nested from the inside out. The female connector harness 511 is laid on the female connector body 513, and the insertion port on the female connector assembly 51 is formed on the female connector base 514. The first elastic element 515 is made of elastic material, and the elasticity of the material itself enables the movable connection between the female connector body 513 and the female connector support 512. To ensure the stability of the connection between the components, the outer periphery of the first elastic member 515 is provided with a slot 5151, and the outer periphery of the female head base 514 is provided with a locking block 5141 that can be slidably disposed in the slot 5151. To prevent the locking block 5141 from dislodging from the slot 5151, that is, to prevent the female head base 514 from dislodging from the female head bracket 514 in the opposite insertion direction, the female head assembly 51 also includes a limiting member 516 disposed outside the insertion port of the female head base 514. The limiting member 516 is used to block the locking block 5141 at the edge of the insertion port of the female head base 514 to prevent the female head base 514 and the first elastic member 515 from dislodging from the female head bracket 512. The limiting member 516 can be fixedly connected to the female head bracket 512 by a sixth mounting pin 86. When the plug is inserted into the socket, it compresses the female connector body 513. The female connector body 513 then drives the female connector base 514 to compress the first elastic element 515. Under the sliding engagement of the locking block 5141 and the locking groove 5151, the first elastic element 515 is deformed under pressure. This deformation absorbs the tolerance along the plug insertion direction.

[0061] The movable connection between the male connector body 523 and the male connector bracket 522 can be described through a third embodiment, as shown in Figures 19-22. In this embodiment, the male connector assembly 52 includes, in addition to the male connector harness 521, the male connector bracket 522, and the male connector body 523, a male connector base 524 for fixing the male connector body 523 and a second elastic element 525 disposed between the male connector base 524 and the male connector bracket. The male connector body 523 is movably connected to the male connector bracket 522 through the second elastic element 525, and the plug is formed on the male connector body 523. The second elastic element 525 is similar to the first elastic element 515, and can be made of an elastic material to achieve elastic deformation through the elasticity of the material itself, or it can be a spring or other element that achieves elastic deformation through compression deformation. In this embodiment, the second elastic element 525 is a spring element. Specifically, the second elastic element 525 is a spring, one end of which is fixed to the male connector base 524 and the other end of which is fixed to the male connector bracket 522. When the plug is inserted into the socket, it pushes the male connector base 524 to compress the second elastic element 525. The second elastic element 525 absorbs the tolerance along the plug insertion direction through compression deformation under pressure.

[0062] Furthermore, a guide pin 527 is fixed on the male connector base 524. The female connector assembly 51 includes a female connector harness 511 and a female connector bracket 512 for laying the female connector harness 511. The socket is opened on the female connector bracket 512. The female connector assembly 51 also includes a pin hole 518 for inserting the guide pin 527. The guide pin 527 is fixed on the male connector base 524 and located around the male connector body 523. The pin hole 518 is opened on the female connector bracket 512 and located around the socket. Both the guide pin 527 and the pin hole 518 extend along the plug insertion direction, and the top of the guide pin 527 extends beyond the male connector body 523 and is formed into a cone. Correspondingly, the entrance of the pin hole 518 can be formed with a relatively enlarged flare to make it easier to insert the corresponding guide pin 527. The guide pin 527 and the pin hole 518 are designed to guide the plug in a direction perpendicular to the insertion direction before insertion, thus absorbing tolerances between the plug and the socket in this direction and ensuring accurate contact between the male and female wire harnesses 521 and 511 after insertion. The guide pin 527 is preferably arranged in pairs, with each pair symmetrically positioned on both sides of the plug. In this embodiment, to minimize the thickness of the mating assembly, only one pair of guide pins 527 is provided, symmetrically positioned on the left and right sides of the plug. Correspondingly, the number of pin holes 518 is the same as the number of guide pins 527, and their positions correspond one-to-one, allowing the guide pins 527 to be inserted in a corresponding manner, improving the absorption of tolerances in the direction perpendicular to the plug insertion and ensuring a smooth insertion of the socket into the plug. By setting the second elastic element 525, the guide pin 527, and the pin hole 518, the tolerance between the plug and the socket along the insertion direction and along the direction perpendicular to the insertion direction can be achieved.

[0063] Preferably, as shown in Figures 21 and 22, the male connector base 524 has a positioning hole 5241 on the side opposite to the plug (i.e., the male connector body 523). A positioning pin 5221, movably inserted into the positioning hole 5241, is fixed to the male connector bracket 522. The second elastic element 525 is a spring sleeved on the positioning pin 5221, with one end fixed to the male connector bracket 522 or the positioning pin 5221, and the other end fixed to the male connector base 524. The positioning pin 5221 guides and limits the movement of the spring. In some embodiments, the fixed end of the guide pin 527 opposite to the top is fixed through the male connector base 524, and the positioning hole 5241 is formed at the fixed end of the guide pin 527. The other end of the spring can also be fixed to the fixed end of the guide pin 527. Preferably, a ring groove 5242 is formed around the periphery of the positioning hole 5241 (i.e., on the side of the male base 524 opposite to the plug or the fixing end of the guide pin 527). The other end of the spring is secured in the ring groove 5242 to facilitate the installation and removal of the spring. When the spring is in the installed state, the ring groove 5242 can limit the spring's movement. For the paired guide pins 527, the springs can also be paired, corresponding one-to-one with each guide pin 527.
