Description

Technical Field

[0001] This invention relates to the field of wire harness storage technology, and in particular to a wire harness storage box. Background Technology

[0002] Electrical appliances typically need to be connected to a power source or external device via cables during use. To ensure the appliances can move freely within a large space, these cables are usually designed to be quite long. However, excessively long cables, if left unattended, can pose a tripping hazard. Therefore, cable management boxes have emerged to retract power cords or data cables. Currently, most cable management boxes on the market use a spring-loaded mechanism to automatically retract the cable. Users need to continuously pull the cable to maintain the desired length; once released, the cable automatically retracts. This not only increases the number of times the user needs to operate, but also can lead to user fatigue from prolonged pulling. Summary of the Invention

[0003] The main objective of this invention is to provide a wire harness storage box that solves the problem of needing to continuously pull the wire harness to maintain the required length during use.

[0004] To achieve the above objectives, the wire harness storage box proposed in this invention includes a box body, a first winding reel, a coil spring, and a locking mechanism. The box body has a wire outlet on its side wall. The first winding reel is rotatably connected to the box body, and a wire harness is wound on the first winding reel. The free end of the wire harness extends from the wire outlet. The coil spring is disposed within the box body and connected to the first winding reel, used to drive the first winding reel to reset. The locking mechanism includes a positioning pin and a limiting block. One of the positioning pin and the limiting block is disposed on the first winding reel, and the other is disposed on the box body. The positioning pin is a pendulum pin with a rotation center. When the limiting block and the positioning pin contact each other and rotate relative to each other, the limiting block can drive the positioning pin to swing. The positioning pin has a first state of being engaged with the limiting block and a second state of being separated from it.

[0005] In one embodiment, the locking mechanism further includes a reset member, which is disposed together with the positioning pin on the first winding reel or the housing. The reset member is connected to the positioning pin and is used to drive the positioning pin to rotate and reset so that the tip of the positioning pin is locked with the limiting block.

[0006] In one embodiment, the reset component includes a tension spring, which is mounted on the first winding reel together with the positioning pin. The limiting block is mounted on the housing. The two ends of the tension spring are respectively connected to the first winding reel and the positioning pin, for driving the positioning pin to rotate and reset; or, the two ends of the tension spring are respectively connected to the inner wall of the housing and the positioning pin, for driving the positioning pin to rotate and reset.

[0007] In one embodiment, the positioning pin is made of ferromagnetic material, and the reset member includes a magnet. The magnet and the positioning pin are jointly disposed on the first winding spool or the housing. When the positioning pin is in its natural state, the magnet and the tip of the positioning pin are positioned opposite each other.

[0008] In one embodiment, the reset member includes a first spring and a second spring, which are disposed together with the positioning pin on the first winding reel or the housing, and the first spring and the second spring are respectively disposed on both sides of the positioning pin and connected to the positioning pin.

[0009] In one embodiment, the limiting block includes a block body and a step protruding from the block body, and the step protrudes from the side of the block body facing the positioning pin; or, the limiting block has a recessed groove on the side facing the positioning pin.

[0010] In one embodiment, when the positioning pin contacts the limiting block, the distance between the rotation center of the positioning pin and the tip of the positioning pin is defined as a first distance, and the vertical distance from the rotation center of the positioning pin to the contact surface of the limiting block is defined as a second distance, wherein the first distance is greater than the second distance.

[0011] In one embodiment, there are multiple limiting blocks, which are arranged circumferentially on the first winding reel or on the inner wall of the box.

[0012] In one embodiment, the wire harness storage box further includes a plug-in module, which is fixedly disposed on the box body and used to plug into the plug interface of the power supply; the wire harness includes a first wire harness and a second wire harness, the second wire harness having a first fixed end and a second fixed end, the first fixed end being fixedly connected to the plug-in module, the second fixed end being fixedly connected to the first winding reel, one end of the first wire harness being integrally connected to the second fixed end of the second wire harness, and the other end of the first wire harness extending out from the outlet.

[0013] In one embodiment, the wire harness storage box further includes a second winding reel, which is connected to the first winding reel and can rotate synchronously with the first winding reel. The second segment of the wire harness is wound around the second winding reel. A wire-passing hole is provided on the first winding reel, and one end of the first segment of the wire harness passes through the wire-passing hole to be integrally connected with the second fixed end of the second segment of the wire harness.

[0014] In one embodiment, the diameter of the second winding spool is smaller than the diameter of the first winding spool.

[0015] In one embodiment, the number of turns of the wire bundle wound on the second winding spool is defined as N1, and the number of turns of the wire bundle wound on the first winding spool is defined as N2, where N1 / N2 = 0.5 / 1 to 2 / 1.

[0016] To avoid requiring users to continuously pull the cable harness to maintain it at the desired length, this cable harness storage box also includes a locking mechanism. This mechanism comprises a positioning pin and a limiting block. One of the positioning pin and the limiting block is located on the surface of the first winding reel, while the other is located on the inner wall of the top cover, allowing the limiting block and the positioning pin to rotate relative to each other. The positioning pin is a pendulum pin with a center of rotation. When the limiting block rotates to face the positioning pin, it contacts the tip of the positioning pin and moves relative to it. During this process, the limiting block causes the positioning pin to swing. If the external force pulling the cable harness disappears, the positioning pin will lock into place with the limiting block, thus locking the positioning pin and the limiting block and preventing the first winding reel from rotating further, achieving a fixed length for the cable harness.

[0031] Electrical appliances typically need to be connected to a power source or external device via cables during use. To ensure the appliances can move freely within a large space, these cables are usually designed to be quite long. However, excessively long cables, if left unattended, can pose a tripping hazard. Therefore, cable management boxes have emerged to retract power cords or data cables. Currently, most cable management boxes on the market use a spring-loaded mechanism to automatically retract the cable. Users need to continuously pull the cable to maintain the desired length; once released, the cable automatically retracts. This not only increases the number of times the user needs to operate, but also can lead to user fatigue from prolonged pulling.

[0032] To address the above problems, this invention proposes a wire harness storage box 100.

[0033] Please see Figures 1 to 3 The wire harness storage box 100 includes a box body 1, a first winding reel 2, a coil spring 3, and a wire locking mechanism 4. The side wall of the box body 1 has a wire outlet 111. The first winding reel 2 is rotatably connected to the box body 1, and a wire harness 6 is wound on the first winding reel 2. The free end of the wire harness 6 extends from the wire outlet 111. The coil spring 3 is disposed inside the box body 1 and connected to the first winding reel 2, used to drive the first winding reel 2 to reset. The wire locking mechanism 4 includes a positioning pin 41 and a limiting block 42. One of the positioning pin 41 and the limiting block 42 is disposed on the first winding reel 2, and the other is disposed on the box body 1. The positioning pin 41 is a pendulum pin with a rotation center. When the limiting block 42 and the positioning pin 41 come into contact and rotate relative to each other, the limiting block 42 can drive the positioning pin 41 to swing. The positioning pin 41 has a first state of being engaged with the limiting block 42 and a second state of being separated from it.

[0034] The cable harness storage box 100 includes a box body 1 with a bottom shell 11 and a top cover 12. The bottom shell 11 is used to house the first winding reel 2 and the coil spring 3. The top cover 12 is detachably disposed over the opening of the bottom shell 11. One of the positioning pin 41 and the limiting block 42 is disposed on the first winding reel 2, and the other is disposed on the side of the top cover 12 facing the first winding reel 2. The cable harness 6 is wound around the periphery of the first winding reel 2. The free end of the cable harness 6 extends from the cable outlet 111 on the side wall of the box body 1, making it convenient for the user to pull the cable harness 6. The first winding reel 2 is rotatably disposed inside the housing 1. A through hole is provided at the center of the first winding reel 2. The coil spring 3 is disposed inside the through hole, and the inner end of the coil spring 3 is fixedly connected to the housing 1, while the outer end is connected to the first winding reel 2. When the user pulls the cable, the cable harness 6 will drive the first winding reel 2 to rotate. The rotation of the first winding reel 2 will drive the coil spring 3 to retract and store force. After the external force disappears, the first winding reel 2 will automatically rotate back to its original position under the action of the coil spring 3.

[0035] To avoid requiring users to continuously pull the wire harness 6 to maintain it at the desired length, the wire harness storage box 100 is also equipped with a wire locking mechanism 4. The wire locking mechanism 4 includes a positioning pin 41 and a limiting block 42. One of the positioning pin 41 and the limiting block 42 is located on the surface of the first winding reel 2, while the other is located on the inner wall of the upper cover 12, allowing the limiting block 42 and the positioning pin 41 to rotate relative to each other. The positioning pin 41 is a pendulum pin with a center of rotation. When the limiting block 42 rotates to face the positioning pin 41, the limiting block 42 contacts the tip of the positioning pin 41 and rotates relative to it. During this process, the limiting block 42 will cause the positioning pin 41 to swing. At this time, if the wire harness 6 is released, the positioning pin 41 will lock against the limiting block 42, thereby locking the positioning pin 41 and the limiting block 42, preventing the first winding reel 2 from continuing to rotate, and achieving a fixed length for the wire harness 6.

[0036] When the positioning pin 41 contacts the limiting block 42, the distance between the rotation center of the positioning pin 41 and the tip of the positioning pin 41 is defined as the first distance, and the vertical distance from the rotation center of the positioning pin 41 to the side of the limiting block 42 facing the positioning pin 41 is defined as the second distance, where the first distance is greater than the second distance. Therefore, when the limiting block 42 rotates to contact the positioning pin 41, the positioning pin 41 can be actuated by the limiting block 42 and swing.

[0037] The locking mechanism 4 in the wire harness storage box 100 also includes a reset member 43. The reset member 43 and the positioning pin 41 are jointly disposed on the first winding disc 2 or the box body 1. The reset member 43 is connected to the positioning pin 41 and is used to drive the positioning pin 41 to rotate and reset so that the tip of the positioning pin 41 is locked with the limiting block 42.

[0038] Figure 4This is a schematic diagram illustrating the motion state of the wire locking mechanism 4 during the wire pulling process in one embodiment of the wire harness storage box 100. Figure 5 The diagram illustrates the motion state during the cable winding process. The working principle of the cable locking mechanism 4 is as follows: When the user pulls the cable, the cable harness 6 drives the first winding disc 2 to rotate, causing the limiting block 42 and the positioning pin 41 to rotate relative to each other. When the limiting block 42 rotates to contact the positioning pin 41, because the distance between the tip of the positioning pin 41 and its rotation center is greater than the vertical distance between the rotation center and the contact surface of the limiting block 42, the positioning pin 41 will be propelled by the limiting block 42 and swing into an inclined state. The tip of the positioning pin 41 will then contact the contact surface of the limiting block 42. At this time, under the action of the reset member 43, the positioning pin 41 will tend to rotate in the opposite direction, so that the tip of the positioning pin 41 abuts and locks against the contact surface of the limiting block 42, thereby preventing the limiting block 42 and the positioning pin 41 from continuing to rotate relative to each other, and thus preventing the first winding disc 2 from continuing to rotate. At this time, the user can feel the resistance to pulling the cable. If the cable harness 6 is released at this time, the length of the cable harness 6 pulled out will be locked. If the wire harness 6 is pulled further, as long as the pulling force of the wire harness 6 is greater than the resistance applied by the reset member 43, the wire harness 6 can be stretched to the required length. If the wire harness 6 is to be retracted, an external force is applied to rotate the first winding disc 2 in the opposite direction so that the positioning pin 41 and the limiting block 42 are separated from each other. The first winding disc 2 can then continue to automatically reverse under the action of the winding spring 3, thereby realizing the winding of the wire harness 6.

[0039] In one embodiment of the present invention, the reset member 43 is a tension spring, which is mounted together with the positioning pin 41 on the surface of the first winding reel 2. The limiting block 42 is mounted on the inner wall of the housing 1. The two ends of the tension spring are respectively connected to the first winding reel 2 and the positioning pin 41 to drive the positioning pin 41 to rotate and reset. When the first winding reel 2 rotates, the positioning pin 41 and the tension spring on it will rotate together with the first winding reel 2, thereby moving closer to or away from the limiting block 42. The positioning pin 41 has a first side facing the pulling direction and a second side facing the winding direction. The first side and the second side are separated by the bisector of its rotation center. Figure 4 and Figure 5 In the illustrated embodiment, the pulling direction is counterclockwise and the winding direction is clockwise. Of course, in actual applications, the pulling and winding directions can be interchanged. One end of the tension spring is connected to the first winding disc 2, and the other end of the tension spring is connected to the second side of the positioning pin 41.

[0040] Alternatively, the reset element 43 is a tension spring, which is mounted on the inner wall of the housing 1 together with the positioning pin 41. The limiting block 42 is mounted on the surface of the first winding reel 2. The two ends of the tension spring are connected to the inner wall of the housing 1 and the positioning pin 41, respectively, to drive the positioning pin 41 to rotate and reset. When the first winding reel 2 rotates, the limiting block 42 on it rotates with the first winding reel 2, thereby moving closer to or away from the limiting block 42. Similarly, the positioning pin 41 has a first side facing the pulling direction and a second side facing the winding direction, wherein one end of the tension spring is connected to the inner wall of the housing 1, and the other end of the tension spring is connected to the second side of the positioning pin 41.

[0041] Figure 4 and Figure 5 The reset element 43 is a tension spring. When the positioning pin 41 is not in contact with the limiting block 42, the tension spring is neither stretched nor compressed. When the positioning pin 41 rotates to face the limiting block 42, and the positioning pin 41 swings due to the push of the limiting block 42, the tension spring is stretched. Under the tension of the tension spring, the positioning pin 41 tends to rotate in the opposite direction. At this time, the tip of the positioning pin 41 abuts and locks against the contact surface of the limiting block 42, thereby locking the positioning pin 41 and the limiting block 42, and thus achieving the fixed length of the wire harness 6. The point of application of the tension spring and the positioning pin 41 is located on the side of the positioning pin 41 facing the wire take-up direction. When the wire harness 6 needs to be pulled out, such as... Figure 4 As shown, the rotation direction of the positioning pin 41 under the action of the tension spring is clockwise, which is opposite to the rotation direction of the first winding disc 2. At this time, releasing the wire harness 6 can make the positioning pin 41 and the limiting block 42 lock together; when the wire harness 6 needs to be retracted, as... Figure 5 As shown, the rotation direction of the positioning pin 41 under the action of the tension spring is the same as the rotation direction of the first winding disc 2. The positioning pin 41 will not exert opposite resistance on the limiting block 42. At this time, it is only necessary to slightly pull the wire harness 6 to separate the positioning pin 41 from the limiting block 42 and then release the wire harness. The first winding disc 2 can automatically and smoothly wind up the wire harness 6 under the action of the winding spring, without the need for manual rotation of the first winding disc 2 to unlock.

[0042] In another embodiment of the present invention, the positioning pin 41 is made of a ferromagnetic material such as iron, cobalt, or nickel that can be attracted by a magnet. In this case, the reset member 43 can be a magnet. The magnet and the positioning pin 41 are jointly disposed on the disc surface of the first winding reel 2 or the inner wall of the box 1. When the positioning pin 41 is in its natural state, that is, in a state where it is not swinging, the magnet and the tip of the positioning pin 41 are positioned opposite each other. When the positioning pin 41 rotates to be opposite the limiting block 42, and the positioning pin 41 swings due to the push of the limiting block 42, the tip of the positioning pin 41 moves away from the magnet. Under the magnetic attraction of the magnet, the tip of the positioning pin 41 tends to rotate in the opposite direction, thereby making the tip of the positioning pin 41 abut and lock with the contact surface of the limiting block 42, thereby locking the positioning pin 41 and the limiting block 42, and thus achieving the fixed length of the wire harness 6. At this time, when the wire harness 6 needs to be wound up, the reverse rotation of the first winding reel 2 will cause the positioning pin 41 to swing in the opposite direction. The tip of the positioning pin 41 will also abut and lock against the contact surface of the limiting block 42 under the magnetic attraction of the magnet. At this time, it is necessary to manually rotate the first winding reel to release the locking of the positioning pin 41 by the limiting block 42, so that the first winding reel 2 can continue to wind up the wire harness 6.

[0043] exist Figure 6 and Figure 7 In the illustrated embodiment, the reset member 43 includes a first spring 431 and a second spring 432. The first spring 431 and the second spring 432 are disposed together with the positioning pin 41 on the first winding reel 2 or the housing 1, and the first spring 431 and the second spring 432 are respectively disposed on both sides of the positioning pin 41 and connected to the positioning pin 41. When the positioning pin 41 is in its natural state, that is, in a state where it does not swing, the first spring 431 and the second spring 432 are both in a state where they are neither stretched nor compressed. When the wire harness 6 is pulled out, the positioning pin 41 rotates to be opposite to the limiting block 42. When the positioning pin 41 swings due to the push of the limiting block 42, the first spring 431 is in a stretched state and the second spring 432 is in a compressed state. Under the elastic force of the first spring 431 and the second spring 432, the positioning pin 41 will have a tendency to rotate in the opposite direction, thereby causing the tip of the positioning pin 41 to abut and lock against the contact surface of the limiting block 42, thereby locking the positioning pin 41 and the limiting block 42, and thus achieving the fixed length of the wire harness 6. At this time, when the wire harness 6 needs to be wound up, the reverse rotation of the first winding reel 2 will cause the positioning pin 41 to swing in the opposite direction, such as... Figure 7 As shown, at this time, the first spring 431 is in a compressed state and the second spring 432 is in a stretched state. The positioning pin 41 will also tend to rotate in the opposite direction under the elastic force of the first spring 431 and the second spring 432. At this time, it is necessary to manually rotate the first winding disc to release the locking of the limiting block 42 on the positioning pin 41, so that the first winding disc 2 can continue to wind the wire harness 6.

[0044] exist Figures 4 to 7In the illustrated embodiment, the limiting block 42 includes a block body 421 and a step 422 protruding from the block body 421, with the step 422 protruding from the side of the block body 421 facing the positioning pin 41. During the cable pulling process, when the limiting block 42 rotates to face the positioning pin 41, the step 422 will first contact the tip of the positioning pin 41 and rotate it. At the instant the step 422 separates from the tip of the positioning pin 41, the positioning pin 41 will momentarily impact the block body 421 under the action of the reset member 43. At this time, the user will hear a crisp click, thus reminding the user that the cable harness 6 can be released to achieve the fixed length of the cable harness 6. At the same time, the step 422 acts as a block for the positioning pin 41, ensuring that the positioning pin 41 remains stably locked.

[0045] In the embodiment shown in 3, the limiting block 42 has a recessed slot 423 on the side facing the positioning pin 41. When the tip of the positioning pin 41 is inserted into the slot 423 under the action of the reset member 43, the user can hear a crisp click sound, which can also remind the user to release the wire harness 6 and ensure that the positioning pin 41 is stably in the locked state.

[0046] One embodiment of the wire harness storage box 100 also includes a second winding reel 5, which is connected to the first winding reel 2 and can rotate synchronously with the first winding reel 2. The diameter of the second winding reel 5 is smaller than the diameter of the first winding reel 2. The wire harness 6 is first wound around the second winding reel 5 and then around the first winding reel 2.

[0047] The second winding reel 5 and the first winding reel 2 can be integrated or separate and then connected. The second winding reel 5 extends the length of the cable harness 6, allowing it to be pulled out to a greater maximum length. Furthermore, with the cable harness 6 having the same maximum length, using two winding reels reduces the volume of the housing 1. When the user pulls the cable, the cable harness 6 will cause the first winding reel 2 and the second winding reel 5 to rotate synchronously. When the positioning pin 41 and the limiting block 42 lock together, the first winding reel 2 and the second winding reel 5 will stop synchronously. When the positioning pin 41 and the limiting block 42 separate and release the cable harness 6, the first winding reel 2 and the second winding reel 5 can rotate in opposite directions under the action of the coiling spring 3, thus winding up the cable harness 6.

[0048] Specifically, the number of turns of the wire harness 6 wound on the second winding reel 5 is defined as N1, and the number of turns of the wire harness 6 wound on the first winding reel 2 is defined as N2, where N1 / N2 = 0.5 / 1 to 2 / 1. That is, when the wire harness 6 is not pulled out, the number of turns of the wire harness 6 on the second winding reel 5 is at least half the number of turns of the wire harness 6 on the first winding reel 2, and at most twice the number of turns of the wire harness 6 on the first winding reel 2. This allows the wire harness 6 of this wire harness storage box 100 to have different specifications, thereby meeting the usage needs of different scenarios.

[0049] In this wire harness storage box 100, there can be multiple limiting blocks 42, which are arranged circumferentially on the surface of the first winding reel 2 or on the inner wall of the box body 1. For example, when there are two limiting blocks 42, the wire harness 6 can be locked once every 180° rotation of the first winding reel 2; when there are three limiting blocks 42, the wire harness 6 can be locked once every 120° rotation of the first winding reel 2; and when there are four limiting blocks 42, the wire harness 6 can be locked once every 90° rotation of the first winding reel 2. In actual applications, the number of limiting blocks 42 can also be more than four, which is not limited here.

[0050] Matching medical devices typically include a main unit and a handle. The handle is usually equipped with a long cable harness to connect to the main unit. This cable harness storage box 100 can be used in matching medical devices to store the power cord of the handle.

[0051] At this time, the wire harness storage box 100 also includes a plug-in module, which is fixedly mounted on the box body. The plug-in module includes a spring pin for plugging into the power supply's connector. The wire harness includes a first wire harness and a second wire harness. The second wire harness has a first fixed end and a second fixed end. The first fixed end is fixedly connected to the plug-in module, and the second fixed end is fixedly connected to the first winding reel 2. One end of the first wire harness is integrally connected to the second fixed end of the second wire harness, and the other end of the first wire harness extends from the outlet 111.

[0052] It is easy to understand that the positions of various points in a single-segment wire harness will shift during the winding and coiling process, making it impossible for it to remain in the designated position and connect to the plug-in module. Therefore, this technical solution divides the wire harness 6 into a first segment and a second segment. The second segment is a wire harness with fixed ends, having a first fixed end and a second fixed end. The first fixed end is fixedly connected to the plug-in module, and the second fixed end is fixedly connected to the first winding reel 2. Subsequently, one end of the first segment is integrally connected to the second fixed end of the second segment, and the other end of the first segment extends from the outlet 111 to connect to the handle. Since both ends of the second segment are fixed, when the user picks up the handle and pulls the cable, only the first segment extends, while the second segment does not. This ensures that the first fixed end of the second segment is always fixedly connected to the plug-in module and will not pull on the plug-in module, thus ensuring that the plug-in module is always plugged into the host's connector.

[0053] This embodiment ensures that when the first winding disc rotates, the first fixed end of the second section of the wire harness remains connected to the plug-in module. At this time, the wire harness storage box 100 can serve as a transfer structure between the main unit and the handle. The plug-in module of the wire harness storage box 100 can be plugged into the plug-in interface of the main unit. At this time, the wire harness can be extended as long as the handle needs to be pulled out, avoiding the problem of wire harness scattering and tangling during operation, and improving the safety and convenience of use.

[0054] Furthermore, one embodiment of the wire harness storage box 100 also includes a second winding reel 5, which is connected to the first winding reel 2. The second winding reel 5 and the first winding reel 2 can be integrally set or separately set and then connected together, so that the second winding reel can rotate synchronously with the first winding reel 2. The second segment of the wire harness is wound around the second winding reel 5. A wire through hole is opened on the first winding reel, and one end of the first segment of the wire harness passes through the wire through hole to be integrally connected with the second fixed end of the second segment of the wire harness.

[0055] In this embodiment, the second winding reel 5 is used to wind and release the second section of wire harness, and the specific process is as follows. When the user picks up the handle and pulls the wire, the second winding reel 5 and the first winding reel 2 rotate together. The first section of wire harness will extend outward under the rotation of the first winding reel 2. Since the first fixed end of the second section of wire harness is fixedly connected to the plug-in module, and the second fixed end of the second section of wire harness is fixedly connected to the first winding reel 2, the second section of wire harness will centrifugally spread under the rotation of the second winding reel 5, that is, gradually approach the side wall of the housing 1 until it abuts against the side wall of the housing 1. When the external force pulling the wire harness disappears, the first winding reel 2 and the second winding reel 5 can rotate in opposite directions together under the action of the coiling spring 3. The first section of wire harness will be wound up under the rotation of the first winding reel 2, and the second section of wire harness will be wound inward under the rotation of the second winding reel 5, that is, gradually approach the second winding reel 5 until it is tightly wrapped around the periphery of the second winding reel 5.

[0056] In this embodiment, by setting a second winding reel 5, the second section of the wire harness can be wound in a concentric direction or unwound in a centrifugal manner, thereby avoiding the phenomenon of the second section of the wire harness generating torque or knots during the rotation of the first winding reel 2, which would cause the first winding reel and the second winding reel to jam.

[0057] The diameter of the second winding reel 5 is smaller than that of the first winding reel 2, so as to ensure that the second section of the wire harness has a certain amount of room to move between the first winding reel 2 and the housing 1.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
