Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to an adjustment device and a connecting wire assembly. Background Technology

[0002] Connecting cables are widely used in various electronic devices, and with the continuous development of electronic devices, the number of connecting cables in a single electronic device is also increasing. Currently, electronic devices are usually equipped with wire connectors for connecting the two ends of the connecting cables, and have reserved wiring grooves for accommodating the connecting cables according to the pre-designed wiring path.

[0003] The required length of the connector varies depending on the installation location of the connector and the wiring path. Manufacturing processes and other factors may cause a discrepancy between the actual and designed length of the connector. Since the length of the connector cannot be adjusted, it is necessary to redesign or remanufacture the connector, resulting in higher production costs. Summary of the Invention

[0004] The purpose of this application is to provide an adjustment device and a connecting wire assembly that can solve the technical problem that the length of the connecting wire cannot be adjusted, thus requiring the redesign or production of the connecting wire, resulting in high production costs for the connecting wire.

[0005] In a first aspect, embodiments of this application provide an adjustment device for connecting a connecting wire, the connecting wire including a first end and a second end disposed opposite to each other, the first end including a fixed portion and a movable portion, the movable portion being closer to the second end than the fixed portion, the adjustment device comprising:

[0006] The device body is fixedly connected to the fixed part, and the device body is provided with a receiving groove for receiving the movable part;

[0007] A cam, the cam being located within the receiving groove and rotatable within the receiving groove, the cam including a protruding end that abuts against the movable portion;

[0008] A drive assembly for driving the cam such that the protruding end reciprocates between a first position and a second position, wherein when the protruding end moves from the first position to the second position, the protruding end pushes the movable portion such that the movable portion extends out of the receiving groove.

[0009] Secondly, embodiments of this application provide a connecting wire assembly, including a connecting wire and an adjustment device as described in the first aspect, wherein the connecting wire includes a first end and a second end disposed opposite to each other, and at least one of the first end and the second end of the connecting wire is connected to the adjustment device.

[0010] In this embodiment, the adjusting device includes a device body, a cam, and a drive assembly. When the protruding end of the cam moves from a first position to a second position, the protruding end pushes the movable portion of the connecting wire, causing the movable portion to extend out of the receiving groove, thereby increasing the length of the connecting wire outside the receiving groove. When the protruding end moves from the second position to the first position, the movable portion can be retracted into the receiving groove, thereby reducing the length of the connecting wire outside the receiving groove. When there is a deviation between the actual length and the designed length of the connecting wire, the length of the connecting wire can be adjusted by the reciprocating movement of the protruding end between the first and second positions. This allows the connecting wire to better adapt to the installation position and routing path of the wire connector, reducing the production cost of the connecting wire. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] Please see Figure 1 , Figure 1This is one of the structural diagrams of the adjustment device provided in the embodiments of this application. The adjustment device provided in the embodiments of this application is used to connect a connecting line, the connecting line including a first end and a second end disposed opposite to each other, the first end including a fixed portion 10 and a movable portion 20, the movable portion 20 being closer to the second end than the fixed portion 10, such as... Figure 1 As shown, the adjusting device includes:

[0018] The device body 30 is fixedly connected to the fixed part 10. The device body 30 is provided with a receiving groove 301 for receiving the movable part 20.

[0019] Cam 40, which is located in the receiving groove 301 and can rotate in the receiving groove 301, includes a protruding end 401, which abuts against the movable part 20;

[0020] A drive assembly 50 is used to drive the cam 40, causing the protruding end 401 to reciprocate between a first position and a second position. When the protruding end 401 moves from the first position to the second position, the protruding end 401 pushes the movable part 20, causing the movable part 20 to extend out of the receiving groove 301.

[0021] The connecting wire used for the adjustment device provided in this embodiment can be any optional connecting wire. Exemplarily, the connecting wire is a coaxial cable or a flexible printed circuit (FPC). For ease of description, in subsequent embodiments, a coaxial cable will be used as an example. In specific implementation, at least one end of the coaxial cable can be connected to the adjustment device, and the adjustment device can be connected to the wire base, thereby fixing the coaxial cable to the wire base.

[0022] The drive assembly 50 is used to drive the cam 40 to rotate. During the rotation of the cam 40, the protruding end 401 reciprocates between a first position and a second position. Depending on the rotation angle of the cam 40, the protruding end 401 can also remain at any position between the first and second positions. It should be understood that the first and second positions are different depending on the range of rotation angles of the cam 40.

[0023] When the protruding end 401 moves from the first position to the second position, the protruding end 401 pushes the movable part 20. Since the fixed part 10 is fixedly connected to the device body 30, with the protruding end 401 as the dividing line, the curvature of the movable part 20 near the fixed part 10 decreases, and the end of the movable part 20 away from the fixed part 10 extends out of the receiving groove 301. In this case, the length of the part of the connecting line inside the receiving groove 301 becomes shorter, which is equivalent to increasing the length of the part of the connecting line outside the receiving groove 301.

[0024] It should be understood that the distance between the protruding end 401 of the cam 40 and the cam shaft is the largest, and the protruding end 401 abuts against the movable part 20. However, the distance between other positions of the cam 40 and the cam shaft is smaller than the distance between the protruding end 401 and the cam shaft. Therefore, other positions of the cam 40 may abut against the movable part 20 or may not abut against the movable part 20.

[0025] Optionally, in some embodiments, when the protruding end 401 is in the first position, the length of the movable portion 20 within the receiving groove 301 is a first length, and when the protruding end 401 is in the second position, the length of the movable portion 20 within the receiving groove 301 is a second length, wherein the first length is greater than the second length.

[0026] For ease of understanding, the following explanation uses the case where only the first end of the connecting wire is connected to the adjusting device as an example. In a specific implementation, exemplarily, the adjusting device is connected to the first end of the connecting wire, and both the adjusting device and the second end of the connecting wire are connected to a wire connector. The connecting wire between the adjusting device and the second end of the connecting wire is located within a cable tray, and the length of this portion of the connecting wire is denoted as the target length. When the protruding end 401 is in the first position, the target length reaches its minimum value; when the protruding end 401 is in the second position, the target length reaches its maximum value. Due to the adjustment device, the target length can vary between the aforementioned maximum and minimum values.

[0027] In this embodiment of the application, when the protruding end 401 is in the first position, the length of the movable part 20 in the receiving groove 301 is the first length, and when the protruding end 401 is in the second position, the length of the movable part 20 in the receiving groove 301 is the second length. The difference between the first length and the second length is the range of length variation of the connecting line.

[0028] To facilitate understanding, the following explanation will use coaxial cable as an example. Based on the first and second lengths, the range of length variation of the coaxial cable can be calculated. By setting coaxial cables of different nominal lengths, the entire length of coaxial cables within a certain range can be covered, thereby achieving standardized design and production of coaxial cables.

[0029] For example, in some embodiments, the first length corresponding to the adjusting device is 20mm and the second length is 14mm. Therefore, when the adjusting device is connected to one end of the coaxial line, the length variation range of the coaxial line is 6mm. Thus, four nominal lengths of coaxial lines—100mm, 105mm, 110mm, and 115mm—are provided. The length variation range (6mm) should be slightly larger than the nominal length span (5mm), thus achieving full coverage of coaxial line lengths within the range of 100mm to 120mm. That is, for coaxial lines within this length range, only an adjusting device with a length variation range of 6mm needs to be selected, along with a coaxial line of a specific nominal length, eliminating the need for complex or repetitive work during design and production. Of course, connecting adjusting devices to both opposite ends of the coaxial line can further expand the length variation range of the coaxial line; see the foregoing for details, which will not be elaborated upon here.

[0030] Therefore, it can be seen that the length of the coaxial cable can be adjusted by connecting an adjustment device to the end of the coaxial cable. This design avoids the need to design coaxial cables of varying lengths for each project, and eliminates the problems associated with redesigning and reproducing coaxial cables during rework. For designers, by selecting coaxial cables of the appropriate nominal length and using suitable adjustment devices, standardized selection of coaxial cables within a certain length range can be achieved, saving significant time on repetitive design and maximizing cost savings.

[0031] In this embodiment, the adjusting device includes a device body 30, a cam 40, and a drive assembly 50. When the protruding end 401 of the cam 40 moves from a first position to a second position, the protruding end 401 pushes the movable portion 20 of the connecting wire, causing the movable portion 20 to extend out of the receiving groove 301, thereby increasing the length of the connecting wire outside the receiving groove 301. When the protruding end 401 moves from the second position to the first position, the movable portion 20 can be retracted into the receiving groove 301, thereby decreasing the length of the connecting wire outside the receiving groove 301. When there is a deviation between the actual length and the designed length of the connecting wire, the length of the connecting wire can be adjusted by the reciprocating movement of the protruding end 401 between the first and second positions, thereby allowing the connecting wire to better adapt to the installation position and routing path of the wire connector, reducing the production cost of the connecting wire.

[0032] It should be understood that the specific manner in which the device body 30 and the fixing part 10 are fixedly connected is not limited here. For example, in some embodiments, the device body 30 and the fixing part 10 are bonded together, while in other embodiments, the device body 30 and the fixing part 10 are snapped together.

[0033] It should be noted that, in this embodiment, the specific shape and size of the receiving groove 301 are not limited. Optionally, as... Figure 1 As shown, in some embodiments, the receiving groove 301 includes a first receiving groove 3011, a second receiving groove 3012 and a third receiving groove 3013 connected in sequence;

[0034] The shape of the first receiving groove 3011 matches the fixed part 10, and the first receiving groove 3011 is used to receive the fixed part 10 and is fixedly connected to the fixed part 10;

[0035] The cam 40 is located within the second receiving groove 3012, and there is a gap between the cam 40 and the inner wall of the second receiving groove 3012. A portion of the movable part 20 is located within the gap.

[0036] The third receiving groove 3013 has a first opening 302 formed on the side wall of the device body 30. Another part of the movable part 20 is located in the third receiving groove 3013 and extends out of the device body 30 through the first opening 302.

[0037] In this embodiment, the first receiving groove 3011 is used to receive the fixed part 10, the second receiving groove 3012 is used to receive the cam 40 and a part of the movable part 20, and the third receiving groove 3013 is used to receive another part of the movable part 20.

[0038] The specific method by which the first receiving groove 3011 is fixedly connected to the fixing part 10 is not limited here. Exemplarily, in some embodiments, the fixing part 10 can be inserted into the first receiving groove 3011 by matching the dimensional tolerances of the first receiving groove 3011 and the fixing part 10. In other embodiments, the size of the first receiving groove 3011 is slightly larger than the size of the fixing part 10, and after the fixing part 10 is placed into the first receiving groove 3011, the fixing part 10 is then bonded and fixed to the first receiving groove 3011.

[0039] Please see Figure 2 For example, a fixed rod 304 is provided in the second receiving groove 3012, and a cam 40 is sleeved on the fixed rod 304 and rotates around the fixed rod 304. A gap is provided between the outer contour of the cam 40 and the inner wall of the second receiving groove 3012, and a part of the movable part 20 is arranged around the outer contour of the cam 40 and located in the gap.

[0040] It should be understood that the clearance size needs to ensure that the protruding end 401 can reciprocate between the first and second positions. Since the distance between the cam 40 and the cam shaft at all positions other than the protruding end 401 is smaller than the distance between the protruding end 401 and the cam shaft, the clearance size between the cam 40 and the inner wall of the second receiving groove 3012 at all positions other than the protruding end 401 should be relatively large. The movable part 20 located within this clearance is in an extended state, without bending or friction.

[0041] The movable part 20 can extend out of the receiving groove 301 or retract into the receiving groove 301 through the first opening 302. Therefore, when the movable part 20 is located in the third receiving groove 3013, there is a gap between the movable part 20 and the side wall of the third receiving groove 3013, thereby ensuring that the movable part 20 can move in the third receiving groove 3013, reducing the friction between the connecting wire and the inner wall of the third receiving groove 3013 during the movement, and reducing the impact on the performance of the connecting wire.

[0042] In this embodiment of the application, the receiving groove 301 includes a first receiving groove 3011, a second receiving groove 3012, and a third receiving groove 3013 connected in sequence. By setting the first receiving groove 3011, the second receiving groove 3012, and the third receiving groove 3013, a certain limiting effect can be played on the connecting wire, improving the connection stability between the adjusting device and the connecting wire, while keeping the first end of the connecting wire in an extended state, reducing the impact on the connecting wire.

[0043] Optionally, in some embodiments, when the protruding end 401 is in the first position, the protruding end 401 pushes the first contact segment of the movable portion 20 to abut against the inner wall of the receiving groove 301;

[0044] When the protruding end 401 is in the second position, the protruding end 401 pushes the second contact segment of the movable part 20 to abut against the inner wall of the receiving groove 301, and the second contact segment is closer to the second end of the connecting line than the first contact segment.

[0045] In this embodiment, the second contact segment is closer to the second end of the connecting wire than the first contact segment. During the movement of the protruding end 401 from the first position to the second position, the protruding end 401 does not directly pull the movable part 20, but rather adjusts the curvature of the movable part 20 within the receiving groove 301 by pushing different segments of the movable part 20 against the inner wall of the receiving groove 301, thereby adjusting the length of the movable part 20 within the receiving groove 301. Through this arrangement, the pulling force exerted by the cam 40 on the connecting wire is reduced, the impact of the cam 40 on the connecting wire is decreased, and the service life of the connecting wire is extended.

[0046] Please see Figure 3When the protruding end 401 is in the first position, the protruding end 401 pushes the connecting line, and the first contact section of the movable part 20 is clamped and fixed on the inner wall of the receiving groove 301. The connecting line between the first contact section and the fixed part 10 has a large curvature.

[0047] Please see Figure 4 When the protruding end 401 moves from the first position to the second position, the second contact section of the movable part 20 is clamped and fixed to the inner wall of the receiving groove 301, and the curvature of the connecting line between the second contact section and the fixed part 10 becomes smaller.

[0048] Optionally, in some embodiments, the outer contour of the cam 40 is provided with a first clamping portion 402, the shape of the first clamping portion 402 matching the movable portion 20;

[0049] When the protruding end 401 is in the first position, the first contact segment is at least partially located within the first clamping portion 402; when the protruding end 401 is in the second position, the second contact segment is at least partially located within the first clamping portion 402.

[0050] Please see Figure 2 For example, in some embodiments, the first clamping portion 402 is arc-shaped. Furthermore, in other embodiments, the first clamping portion 402 is semi-circular, and the size of the first clamping portion 402 matches the size of the connecting line.

[0051] During the rotation of the cam 40, the movable part 20 can move relative to the first clamping part 402 without rubbing against the inner wall of the first clamping part 402, so as to ensure that the connecting line remains stretched in the routing path in this state without bending or friction.

[0052] In this embodiment of the application, the outer contour of the cam 40 is provided with a first clamping part 402. By setting the first clamping part 402, the movable part 20 of the connecting line can play a certain limiting role, reducing the probability of the movable part 20 shifting position, improving the stability when the protruding end 401 pushes the first contact segment or the second contact segment to abut against the inner wall of the receiving groove 301, and reducing the probability of the connecting line bending and rubbing.

[0053] Optionally, in some embodiments, the driving component 50 includes:

[0054] A button lever 501 is capable of reciprocating linear motion along a target direction, wherein the target direction is the axial direction of the button lever 501.

[0055] A connecting rod 502, one end of which is connected to the cam 40, and the other end of which is connected to the button rod 501;

[0056] The button lever 501 can reciprocate linearly along its axial direction to drive the connecting rod 502 to move, and the connecting rod 502 can drive the protruding end 401 to reciprocate between the first position and the second position.

[0057] Please see Figure 1 The drive assembly 50 includes a button lever 501 and a connecting rod 502. By applying forces in different directions to the button lever 501, it can be driven to reciprocate linearly along its axial direction. During this reciprocating linear motion, the force applied to the button lever 501 can be transmitted to the cam 40 via the connecting rod 502, thereby causing the cam 40 to rotate. Exemplarily, in some embodiments, the connecting rod 502 is a crank.

[0058] For ease of understanding, the following will be used as an example. Figure 1 The driving device shown is used as an example for explanation. Figure 1 As shown, the user presses the button lever 501, causing it to move in the target direction toward the cam 40. The button lever 501 pushes the connecting rod 502, which applies a force to the cam 40 through its end connected to the cam 40, causing the cam 40 to rotate clockwise, and the protruding end 401 to rotate from the first position to the second position.

[0059] The user pulls the button lever 501, causing it to move in the target direction away from the cam 40. The button lever 501 pulls the connecting rod 502, which applies a force to the cam 40 through its end connected to the cam 40, causing the cam 40 to rotate counterclockwise, and the protruding end 401 to rotate from the second position to the first position.

[0060] It should be noted that the rotation angle range of the cam 40 varies depending on the maximum travel of the button lever 501 along the target direction. By setting and adjusting the maximum travel of the button lever 501, different first and second positions can be set, which is only to obtain the corresponding adjustment device with different length variation range.

[0061] In this embodiment of the application, the drive component 50 includes a button lever 501 and a connecting rod 502. By setting the button lever 501 and the connecting rod 502, the reciprocating linear motion of the button lever 501 can be converted into the reciprocating rotational motion of the cam 40, which improves the ease of operation of driving the cam 40 to rotate and allows the user to better control the rotation of the cam 40.

[0062] Optionally, in some embodiments, there are two drive components 50, and the button levers 501 of the two drive components 50 are coaxially arranged. When both button levers 501 of the two drive components 50 move toward the cam 40 along the target direction, the protruding end 401 rotates from the first position to the second position. When both button levers 501 of the two drive components 50 move away from the cam 40 along the target direction, the protruding end 401 rotates from the second position to the first position.

[0063] Please see Figures 2-4 There are two drive components 50, and the two drive components 50 have the same structure. The button levers 501 of the two drive components 50 are coaxial and arranged opposite each other. When both button levers 501 of the two drive components 50 move towards the cam 40, both button levers 501 apply a force to the cam 40 through their connecting rods 502, and simultaneously push the cam 40 to rotate clockwise. When both button levers 501 of the two drive components 50 move away from the cam 40, both button levers 501 apply a force to the cam 40 through their connecting rods 502, and simultaneously push the cam 40 to rotate counterclockwise.

[0064] Of course, in some embodiments, the number of drive components 50 can be multiple, and the specific number can be set according to actual needs. In other embodiments, the button levers 501 of the two drive components 50 can also be arranged at an angle.

[0065] In this embodiment, there are two drive components 50, and the button levers 501 of the two drive components 50 are coaxially arranged. This arrangement allows the cam 40 to rotate simultaneously via the two drive components 50, improving the ease of rotating the cam 40.

[0066] Optionally, in some embodiments, the driving component 50 further includes:

[0067] The first fixing block 503 is connected to the device body 30. The first fixing block 503 is provided with a first through hole 5031. One end of the button rod 501 passes through the first through hole 5031 and is connected to the other end of the connecting rod 502.

[0068] A first elastic element 504, the first end of the first elastic element 504 is connected to the first fixing block 503, and the second end of the first elastic element 504 is connected to the button rod 501.

[0069] When the protruding end 401 is in the second position, the first elastic member 504 is in a compressed state.

[0070] The specific structure of the first through hole 5031 is not limited here. Exemplarily, in some embodiments, the size of the first through hole 5031 matches the size of the button lever 501, so that the button lever 501 can only move in the target direction, avoiding positional deviation of the button lever 501 that would affect its use.

[0071] The specific structure of the first elastic element 504 can be set and adjusted according to actual needs, and is not limited here. For example, the first elastic element 504 can be a spring, leaf spring or other elastic components.

[0072] With the protruding end 401 in the second position, the first elastic element 504 is in a compressed state. Since the first elastic element 504 has a tendency to return to its natural state, it provides a force to the button lever 501 along the target direction and away from the cam 40. Without any other external force, the protruding end 401 can automatically move from the second position to the first position under the push of the first elastic element 504.

[0073] In this embodiment of the application, the drive assembly 50 further includes a first fixing block 503 and a first elastic member 504. The first fixing block 503 can improve the stability of the button lever 501 so that the button lever 501 can only move in the target direction. The first elastic member 504 can push the protruding end 401 from the second position to the first position without any other external force.

[0074] Optionally, in some embodiments, when the protruding end 401 is in the first position and the second position, the first elastic member 504 is in a compressed state.

[0075] like Figure 3 As shown, in some optional embodiments, the number of drive components 50 is two. Each of the two drive components 50 has a limiting member 5011 on the side of its button lever 501 away from the connecting rod 502. For example, when the left button lever 501 is accidentally pressed and moves towards the cam 40 in the target direction, since the right button lever 501 is not subjected to external force, the first elastic member 504 sleeved on the right button lever 501 will provide a force to the cam 40 through the button lever 501 and the connecting rod 502, counteracting the force provided by the right button lever 501 to the cam 40, thus reducing the probability of the cam 40 rotating due to accidental pressing of one button lever 501. Through the above arrangement, it is possible to avoid unnecessary loosening of the connecting wire caused by accidental pressing of either button lever 501.

[0076] Optionally, in some embodiments, the device body 30 is provided with a limiting groove 303, the limiting groove 303 includes a first end and a second end disposed opposite to each other, the first end of the limiting groove 303 communicates with the receiving groove 301, and the button rod 501 is at least partially located in the limiting groove 303.

[0077] In some embodiments, the shape and size of the limiting groove 303 match the shape and size of the button lever 501. Exemplarily, in some embodiments, the button lever 501 is cylindrical, and the limiting groove 303 is arc-shaped or semi-circular. In other embodiments, the button lever 501 is cuboid, and the limiting groove 303 is rectangular.

[0078] In some embodiments, the drive assembly 50 further includes a first elastic element 504, which is a spring and is sleeved on the button lever 501. The shape and size of the limiting groove 303 match the shape and size of the spring, and the spring is at least partially located within the limiting groove 303.

[0079] In this embodiment, the device body 30 is provided with a limiting groove 303, which includes a first end and a second end disposed opposite to each other. The first end of the limiting groove 303 communicates with the receiving groove 301, and the button rod 501 is at least partially located within the limiting groove 303. By providing the limiting groove 303, the button rod 501 can be limited to a certain extent, thereby improving the stability of the button rod 501 when it moves along the target direction.

[0080] Optionally, in some embodiments, a limiting member 5011 is provided on the side of the button lever 501 away from the connecting rod 502. The size of the limiting member 5011 is larger than the first through hole 5031. When the protruding end 401 is in the first position, the limiting member 5011 abuts against the inner wall of the second end of the limiting groove 303. The limiting member 5011 is used to limit the maximum travel of the button lever 501 along the target direction.

[0081] Please see Figure 3 When the protruding end 401 is in the first position, because the size of the limiting member 5011 is larger than the first through hole 5031, the button lever 501 has reached its maximum stroke moving towards the cam 40 in the target direction. When the protruding end 401 is in the second position, because the limiting member 5011 abuts against the inner wall of the second end of the limiting groove 303, the button lever 501 has reached its maximum stroke moving away from the cam 40 in the target direction. Therefore, the limiting member 5011 can limit the maximum stroke of the button lever 501 in the target direction, thereby limiting the rotation angle range of the cam 40 and preventing the cam 40 from over-rotating and jamming.

[0082] In some optional embodiments, the adjusting device includes a housing 70. When the device body 30 is connected to the housing 70, the device body 30 and the housing 70 together form a second through hole, which communicates with the receiving cavity. The limiting member 5011 is larger than the second through hole, and when the protruding end 401 is in the first position, the limiting member 5011 abuts against the housing 70. When the device body 30 and the housing 70 are connected, the housing 70 can be understood as the inner wall of the second end of the limiting groove 303.

[0083] Please see Figure 3 In some optional embodiments, the drive assembly 50 further includes a first fixing block 503 and a first elastic element 504. The first elastic element 504 is a spring, which is sleeved on the button lever 501, and its two ends abut against the first fixing block 503 and the limiting element 5011, respectively. When the protruding end 401 is in the first position, the spring is compressed to its maximum compression value, and the button lever 501 has reached its maximum stroke moving towards the cam 40 in the target direction. In this embodiment, by setting the maximum compression value of the spring, the maximum stroke of the button lever 501 moving towards the cam 40 in the target direction can be limited.

[0084] In this embodiment, a limiting member 5011 is provided on the side of the button lever 501 away from the connecting rod 502. The limiting member 5011 is used to limit the maximum travel of the button lever 501 along the target direction. By setting the limiting member 5011, it is possible to avoid the connecting rod 502 from moving excessively and locking up, and to avoid the cam 40 from rotating too much and getting stuck.

[0085] Optionally, in some embodiments, the adjusting device further includes a clamping assembly 60, which is located within the receiving groove 301 and movable within the receiving groove 301;

[0086] During the reciprocating rotation of the protruding end 401 between the first and second positions, the pressing component 60 is used to push the third contact section of the movable part 20 to fit against the outer contour of the cam 40.

[0087] It should be noted that as the cam 40 rotates, the third contact section, which is clamped and fixed between the pressure pulley 601 and the cam 40, is actually a different section of the movable part 20. Depending on the structure of the adjusting device, the third contact section may overlap with the first and second contact sections.

[0088] For example, in such Figure 3 In the case shown, the protruding end 401 corresponds to the pressure pulley 601, therefore the protruding end 401 pushes the movable part 20 to abut against the pressure pulley 601, and the third contact section and the first contact section are at the same position of the movable part 20. Figure 4In the case shown, the third contact segment and the second contact segment are at different positions of the active part 20.

[0089] In this embodiment, the adjusting device further includes a clamping component 60, which is used to push the third contact segment to maintain contact with the outer contour of the cam 40 during rotation, thereby increasing the degree of change in the coaxial line curvature. With the above arrangement, when the protruding end 401 is in the second position, the length of the portion of the movable part 20 extending out of the receiving groove 301 is longer, thereby increasing the range of length variation of the connecting line outside the receiving groove 301 and expanding the applicable range of the connecting line.

[0090] Optionally, in some embodiments, the clamping assembly 60 includes:

[0091] 601 pressure roller;

[0092] The second elastic element 602 is connected to the pressure pulley 601. The second elastic element 602 is in a compressed state and is used to push the pressure pulley 601 toward the cam 40 so that the third contact segment fits against the outer contour of the cam 40.

[0093] The specific structure of the second elastic element 602 can be set and adjusted according to actual needs, and is not limited here. For example, the second elastic element 602 can be a spring, leaf spring or other elastic components.

[0094] For example, in some embodiments, the receiving groove 301 further includes a fourth receiving groove 3014 communicating with the second receiving groove 3012. One end of the second elastic member 602 is connected to the inner wall of the fourth receiving groove 3014, and the other end is connected to the pressing pulley 601. The second elastic member 602 is used to push the pressing pulley 601 into the second receiving groove 3012.

[0095] During the rotation of cam 40, the vertical distance between the pressure roller 601 and cam 40 also changes. When the vertical distance between the pressure roller 601 and cam 40 decreases, the second elastic element 602 provides a force to the pressure roller 601, pushing the pressure roller 601 towards cam 40. The movable part 20 is located in the gap between cam 40 and the second receiving groove 3012. Therefore, after the pressure roller 601 extends from the fourth receiving groove 3014 into the second receiving groove 3012, it will push the movable part 20 towards cam 40 until the third contact section of the movable part 20 is clamped and fixed between the pressure roller 601 and cam 40.

[0096] As the vertical distance between the pressure roller 601 and the cam 40 increases, the cam 40 pushes the pressure roller 601 to move, and the pressure roller 601 provides a force to the second elastic element 602. At this time, the pressure roller 601 is pushed back into the fourth receiving groove 3014. During this process, since the second elastic element 602 is always in a compressed state, the pressure roller 601 and the cam 40 always clamp the third contact section.

[0097] In this embodiment, since the second elastic element 602 is in a compressed state, the deformation of the second elastic element 602 can cause the pressure pulley 601 to always push the third contact segment to fit against the outer contour of the cam 40 during the rotation of the cam 40, thereby improving the flexibility of the pressing assembly 60.

[0098] Optionally, in some embodiments, the pressure pulley 601 is provided with a second clamping portion 6011, the shape of which matches the movable portion 20, and the second clamping portion 6011 is used to accommodate at least a portion of the third contact segment.

[0099] Please see Figure 2 For example, in some embodiments, the second clamping portion 6011 is arc-shaped, and the third contact segment is located within the second clamping portion 6011. Furthermore, in other embodiments, the second clamping portion 6011 is semi-circular, and the size of the second clamping portion 6011 matches the size of the connecting wire.

[0100] During the rotation of the cam 40, the movable part 20 can move relative to the second clamping part 6011 without rubbing against the inner wall of the second clamping part 6011, so as to ensure that the connecting line remains stretched in the routing path in this state without bending or friction.

[0101] In this embodiment of the application, the pressure pulley 601 is provided with a second clamping part 6011. By setting the second clamping part 6011, the movable part 20 can be limited to a certain extent, reducing the probability of the third contact segment shifting position, ensuring that the third contact segment is always clamped between the pressure pulley 601 and the cam 40, and reducing the probability of the connecting wire bending and friction.

[0102] Optionally, in some embodiments, the adjusting device further includes a housing 70, which is connected to and encloses the side of the device body 30 where the receiving groove 301 is provided to form a receiving cavity.

[0103] Please see Figure 2The adjustment device also includes a housing 70, which is disposed on the side of the device body 30 where the receiving groove 301 is provided. The housing 70 is connected to the device body 30 to form a receiving cavity. The first end of the connecting line and the cam 40 are both located in the receiving cavity, and the drive assembly 50 is at least partially located in the receiving cavity.

[0104] In this embodiment, the adjusting device further includes a housing 70, which is connected to and encloses the side of the device body 30 with the receiving groove 301 to form a receiving cavity. The housing 70 provides protection for the first end of the connecting wire, the cam 40, and the drive assembly 50, thus extending the service life of the adjusting device.

[0105] This application embodiment also provides a connecting line assembly, including a connecting line and the above-described adjusting device, wherein the connecting line includes a first end and a second end disposed opposite to each other, and at least one of the first end and the second end of the connecting line is connected to the adjusting device.

[0106] It should be understood that, and it needs to be explained, the first and second lengths corresponding to the adjusting device determine the range of length variation of the connecting line after it is connected to the adjusting device. In embodiments where both the first and second ends of the connecting line are connected to the adjusting device, the range of length variation of the connecting line is further expanded. The range of variation corresponding to the adjusting device connected to the first and second ends of the connecting line can be the same or different.

[0107] The connecting cable assembly provided in this embodiment can be applied to different electronic devices. In a specific implementation, when an adjustment device is connected to the end of the connecting cable, the adjustment device is connected to a pre-installed socket on the electronic device; when no adjustment device is connected to the end of the connecting cable, the end of the connecting cable is connected to the socket.

[0108] In this application embodiment, the aforementioned electronic device may be a computer, mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, e-reader, navigator, digital camera, etc.

[0109] In this embodiment, the adjusting device is the same as the adjusting device in the above embodiments, and its specific structure can be referred to the description in the above embodiments, which will not be repeated here. Since the adjusting device in the above embodiments is used in this embodiment, the connecting wire assembly provided in this embodiment has all the beneficial effects of the adjusting device in the above embodiments.

[0110] Please see Figure 3 and Figure 4 The following will use a specific embodiment as an example to explain the working principle of the adjustment device provided in this application.

[0111] like Figure 3 As shown, in the static state, the first elastic element 504 remains compressed, and the limiting element 5011 of the button rod 501 abuts against the inner wall of the second end of the limiting groove 303, thereby allowing the protruding end 401 to remain in the position as shown. Figure 3 The first position is shown in the diagram. The protruding end 401 of the cam 40 pushes the first contact end to abut against the inner wall of the second receiving groove 3012. The second elastic member 602 remains compressed, pushing the wire pressing pulley 601 downward, and the wire pressing pulley 601 pushes the third contact section to abut against the outer contour of the cam 40. At this time, the circumferential length of the coaxial line in the receiving groove 301 of the adjusting device is at its maximum value. In this embodiment, the first receiving groove 3011 and the third receiving groove 3013 are designed to match the wire diameter of the coaxial line. The outer contour of the cam 40 and the side of the wire pressing pulley 601 are both designed with a first clamping part 402 and a second clamping part 6011 to match the wire diameter of the coaxial line, so as to ensure that the coaxial line remains extended in the wiring path in this state, without bending or friction.

[0112] In this static state, the coaxial cable within the receiving slot 301 has the longest encirclement length. Given a fixed total coaxial cable length, the coaxial cable outside the receiving slot 301 has the shortest length, and this length should be slightly less than the actual wiring path length of the installed coaxial cable. The coaxial cable cannot be properly assembled in this static state, and its length needs to be adjusted.

[0113] like Figure 4 As shown, manually pressing the adjustment button levers 501 on both sides causes the cam 40 to rotate clockwise via the connecting rods 502 on both sides. During the rotation, the second elastic element 602 remains in a compressed state, meaning that the pressure roller 601 always pushes the third contact section to contact the outer contour of the cam 40. Due to the change in position of the protruding end 401 of the cam 40, the coaxial axis is driven and still passes between the pressure roller 601 and the first clamping part 402 and the second clamping part 6011 of the cam 40, maintaining an extended state without bending or friction.

[0114] Compared to a static state, such as Figure 4In the state shown, the length of the coaxial cable inside the receiving groove 301 decreases. With a fixed total length of the coaxial cable, the length of the coaxial cable outside the receiving groove 301 increases. When this length increases to slightly greater than the actual wiring path length of the installed coaxial cable, the adjusting device can be engaged with the cable holder. Then, the adjusting button levers 501 on both sides are released. The adjusting button levers 501 spring back outward under the action of the first elastic element 504, and the cam 40 rotates counterclockwise until the length of the coaxial cable outside the receiving groove 301 is reduced to exactly equal to the actual wiring path length of the installed coaxial cable. At this point, the coaxial cable is tightened, thus completing the assembly of the coaxial cable. It should be noted that, depending on the actual situation, in cases such as… Figure 4 In the state shown, the protruding end 401 can be located at any position between the first position and the second position, or it can be located at the second position.

[0115] In addition, to prevent the connecting rod 502 from locking due to excessive movement, a maximum compression value is set for the first elastic element 504, ensuring that both the button lever 501 and the cam 40 have a certain limit position, thus preventing the cam 40 from rotating excessively. When the cam 40 moves to its limit position, the second elastic element 602 should still remain compressed to ensure that a third contact section is clamped and fixed between the wire pressing pulley 601 and the cam 40, thereby limiting the wire path of the coaxial cable within the receiving groove 301. Drive components 50 are provided on both sides, requiring simultaneous pressure from both sides to drive the cam 40 to rotate, preventing unnecessary loosening of the coaxial cable due to accidental activation of the adjustment button lever 501 on one side.

[0116] The aforementioned adjustment device allows for adjustable coaxial cable length, solving the problem of difficult placement of the coaxial cable during assembly. The adjustment device is simple, reliable, and easy to assemble, improving assembly efficiency, reducing assembly difficulty, and lowering the defect rate.

The specific embodiments described above are merely illustrative and not restrictive.
