Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamp for fixing headphone cables. Background Technology

[0002] Headphone cable clips are typically used in headphones as flat, flexible circuit boards, primarily made of FPC (flexible printed circuit boards). They are generally flat, with a width ranging from a few millimeters to over ten millimeters and a thickness usually less than 1 millimeter. The length varies depending on the headphone's design and internal structure, generally ranging from a few centimeters to over ten centimeters. They can be bent and folded according to the internal space of the headphone, such as at the connection between the headband and earcups of over-ear headphones, and at the connection between the earphone stem and the driver unit cavity of in-ear headphones, where the cable will bend with the structure.

[0003] Common headphone cable clamps on the market can only fix the headphone cable at the point where the cable extends, flattening the cable so that it is on a flat plane. However, this fixing method causes the headphone cable to become tangled, making it inconvenient to solder, which is time-consuming and reduces production efficiency. Utility Model Content

[0004] In view of this, the present invention provides a clamp for fixing headphone cables, the main technical problem to be solved is that the headphone cables are tangled together, making it inconvenient to solder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamp for fixing headphone cables, comprising a base, the base including a bottom, a second groove and a third groove on the upper surface of the bottom, the third groove being located between the two second grooves, a fourth groove inside the second groove, a moving mechanism installed on the inner wall of the second groove, the moving mechanism including a connecting plate, the surface of the connecting plate being movably connected to the inner wall of the second groove, a first rotating shaft fixedly connected to the upper surface of the connecting plate, a moving plate movably connected to the surface of the first rotating shaft, a second rotating shaft movably connected to the inside of the connecting plate, a first pulley fixedly connected to the surface of the second rotating shaft, a rotating mechanism installed inside the moving plate, the rotating mechanism including a third rotating shaft movably connected to the inside of the moving plate, and a pressure roller fixedly connected to the surface of the third rotating shaft.

[0006] By adopting the above technical solution, after placing the end of the headphone cable to be soldered on the upper surface of the base, inserting the cable into multiple third grooves, and then pushing the moving plate, the cable can be straightened and separated and fixed, which facilitates subsequent soldering.

[0007] As a further description of the above technical solution:

[0008] The surface of the third rotating shaft is fixedly connected to the second pulley, the surface of the first pulley is provided with a belt body, the inner wall of the belt body is in contact with the surface of the second pulley, and the pressure roller is located above the third groove.

[0009] By adopting the above technical solution, the rotation of the first pulley is driven to the second pulley by the belt, and the third rotating shaft fixed to the inner wall of the second pulley drives the pressure roller to rotate.

[0010] As a further description of the above technical solution:

[0011] The surface of the movable plate has a first through hole, and the inner wall of the first through hole is movably connected to a first rotating shaft. The surface of the first rotating shaft is fixedly connected to the surface of the connecting plate.

[0012] By adopting the above technical solution, the movable plate can rotate around the first pivot, which facilitates quick and easy handling of the headphone cable and improves the working efficiency of the device.

[0013] As a further description of the above technical solution:

[0014] An adsorption mechanism is installed on the inner wall of the second groove. The adsorption mechanism includes a slider. The slider is movably connected to the inner wall of the second groove. A fifth groove is formed on the upper surface of the slider. An electromagnet is fixedly connected to the inner wall of the fifth groove.

[0015] By adopting the above technical solution, when the moving plate moves, the slider that is confined inside the second groove also slides.

[0016] As a further description of the above technical solution:

[0017] A magnetic block is fixedly connected to the lower surface of the movable plate, and the lower surface of the magnetic block is in contact with the upper surface of the electromagnet. A button is fixedly connected to the upper surface of the base, and a first groove is formed on the upper surface of the base.

[0018] By adopting the above technical solution, the electromagnet is energized under normal conditions. When the earphone cable fixed inside the device is soldered, the electromagnet can be de-energized simply by pressing the button.

[0019] As a further description of the above technical solution:

[0020] The lower surface of the base is equipped with an anti-slip mechanism, which includes a pad. The upper surface of the pad is fixedly connected to the lower surface of the base, and the lower surface of the pad has an anti-slip groove.

[0021] By adopting the above technical solution, the anti-slip groove makes the device less prone to displacement when placed on a table, and facilitates fixation.

[0022] By employing the above technical solution, the headphone cable fixing clamp of this utility model has at least the following beneficial effects:

[0023] 1. Compared with the prior art, this headphone cable fixing clamp, through a pressure roller, a movable plate, and a first pulley, allows the headphone cable to be placed inside the third groove during use. The movable plate is pushed, causing it to move from left to right. A connecting plate mounted at the bottom of the movable plate is movably connected to the first pulley, which is located in an inclined fourth groove, with the inclination direction from left to right. Therefore, when the movable plate moves from left to right, the first pulley adheres to the inner wall of the fourth groove, causing the movable plate to move downwards as it moves to the right. When the first pulley rotates, it drives the second pulley to rotate via the belt body. The inner wall of the second pulley is fixed... The third rotating shaft drives the pressure roller to rotate, straightening and separating the headphone cable inside the third groove, while fixing its position. Compared to conventional devices, which can only fix the headphone cable at the protruding part of the cable harness by flattening it to make it on a flat plane, this method can cause the headphone cable to become tangled, making soldering inconvenient, time-consuming, and reducing production efficiency. In use, this device only requires placing the end of the headphone cable to be soldered on the upper surface of the base, inserting the cable into the multiple third grooves, and then pushing the moving plate to straighten and separate the cable, facilitating subsequent soldering and improving the device's working efficiency.

[0024] 2. Compared with the prior art, this fixed headphone cable clamp uses a magnetic block, a slider, and a moving plate. In use, a magnetic block is fixed at the bottom of the moving plate, and an electromagnet is installed in the corresponding position of the slider and the magnetic block. Under normal conditions, the electromagnet is energized. When the headphone cable fixed inside the device is soldered, simply pressing a button will de-energize the electromagnet. At this time, one end of the moving plate that fixes the magnetic block can be easily lifted around the first pivot, which can quickly pick it up and improve the working efficiency of the device.

A second groove 103 and a third groove 104 are formed on the upper surface of the base 101, located between the two second grooves 103. A fourth groove 105 is formed inside the second grooves 103. A moving mechanism 2 is installed on the inner wall of the second grooves 103. The moving mechanism 2 includes a connecting plate 204, the surface of which is movably connected to the inner wall of the second grooves 103. A first rotating shaft 203 is fixedly connected to the upper surface of the connecting plate 204. A movable plate 201 is movably connected to the surface of the connecting plate 204. A second rotating shaft 205 is movably connected inside the connecting plate 204. A first pulley 206 is fixedly connected to the surface of the second rotating shaft 205. A rotating mechanism 3 is installed inside the movable plate 201. The rotating mechanism 3 includes a third rotating shaft 303, which is movably connected inside the movable plate 201. A pressure roller 304 is fixedly connected to the surface of the third rotating shaft 303. After placing the end of the headphone cable to be soldered on the upper surface of the base 101, the cable is inserted into multiple third grooves 104. Then, by pushing the movable plate 201, the cable can be straightened and separated and fixed, which facilitates subsequent soldering.

[0033] The surface of the third rotating shaft 303 is fixedly connected to the second pulley 302. The surface of the first pulley 206 is provided with a belt body 301. The inner wall of the belt body 301 is in contact with the surface of the second pulley 302. The pressure roller 304 is located above the third groove 104. The belt body 301 drives the rotation of the first pulley 206 to the second pulley 302. Then, the third rotating shaft 303, which is fixed to the inner wall of the second pulley 302, drives the pressure roller 304 to rotate. The surface of the moving plate 201 is provided with a first through hole 202. The inner wall of the first through hole 202 is movably connected to the first rotating shaft 203. The surface of the first rotating shaft 203 is fixedly connected to the surface of the connecting plate 204. The moving plate 201 can rotate around the first rotating shaft 203, which facilitates quick and easy removal of the headphone cable and improves the working efficiency of the device. The inner wall of the second groove 103 is equipped with an adsorption mechanism 4. The adsorption mechanism 4 includes a slider 401. The inner wall of the second groove 103 is movably connected to the slider 401. A fifth groove 402 is formed on the upper surface of block 401. An electromagnet 403 is fixedly connected to the inner wall of the fifth groove 402. When the moving plate 201 moves, the slider 401, which is limited inside the second groove 103, also slides. A magnetic block 404 is fixedly connected to the lower surface of the moving plate 201. The lower surface of the magnetic block 404 is in contact with the upper surface of the electromagnet 403. A button 6 is fixedly connected to the upper surface of the base 101. A first groove 102 is formed on the upper surface of the base 101. When the electromagnet 403 is in the energized state, the electromagnet 403 can be de-energized simply by pressing button 6 when the internal headphone cable is soldered. The lower surface of the base 101 is equipped with an anti-slip mechanism 5, which includes a pad 501. The upper surface of the pad 501 is fixedly connected to the lower surface of the base 101. The lower surface of the pad 501 is provided with an anti-slip groove 502. The anti-slip groove 502 makes it easy to fix the device when it is placed on a table.

[0034] Working principle: When the headphone cable is placed inside the third groove 104, the moving plate 201 is pushed, causing it to move from left to right. A first pulley 206 is movably connected to a connecting plate 204 mounted at the bottom of the moving plate 201. The first pulley 206 is located in the inclined fourth groove 105, with the inclination direction from left to right. Therefore, when the moving plate 201 moves from left to right, the first pulley 206 comes into contact with the inner wall of the fourth groove 105, causing the moving plate 201 to move downwards as it moves to the right. When the first pulley 206 rotates, it drives the second pulley 302 to rotate via the belt body 301. The third rotating shaft 303, fixed to the inner wall, drives the pressure roller 304 to rotate together, straightening and separating the headphone cable inside the third groove 104. At the same time, a magnetic block 404 is fixed at the bottom of the moving plate 201. An electromagnet 403 is installed in the corresponding position of the slider 401 and the magnetic block 404. Under normal conditions, the electromagnet 403 is energized. When the headphone cable fixed inside the device is soldered, the electromagnet 403 can be de-energized by pressing the button 6. At this time, one end of the moving plate 201 that fixes the magnetic block 404 can be easily lifted around the first rotating shaft 203 for quick removal, which improves the working efficiency of the device.
