Description

Technical Field

[0001] This application relates to the field of wire assemblies, and more particularly to a headband wire assembly. Background Technology

[0002] A headband wiring assembly is a device used to integrate the wiring system and structure in head-mounted devices. It lays out signal lines, power lines, and other conductors in the assembly and is used to connect the two ends of the device.

[0003] Currently, most headband cable assemblies still use traditional fixed welding structures for connection and plugging. Existing technologies use magnetic quick-break connections or clips to solve this problem, but these are cumbersome to set up and require force to pull the cable to pull it out, which can easily damage the cable after long-term use. Utility Model Content

[0004] This utility model discloses a headband cable assembly, which aims to solve the technical problems of existing headband cable assemblies in terms of easy cable damage, inconvenient operation, and insufficient reliability in terms of connection and plugging.

[0005] The technical solution of this utility model is as follows: A headband cable assembly includes: a base; a sliding frame movably disposed on the base; a locking mechanism disposed on the sliding frame for engaging with the cable under the action of the sliding frame when the cable is inserted; a spring disposed between the base and the sliding frame for driving the sliding frame to reset when the sliding frame is unlocked; and a locking mechanism for locking the sliding frame when the cable pushes it to the locked position, and releasing the lock when the cable pushes the sliding frame again. This technical solution enables convenient insertion and removal of the cable, avoids directly pulling the cable body, effectively protects the cable, and extends its service life.

[0006] Furthermore, the locking mechanism includes a stop arm and a diamond-shaped block disposed on the sliding frame. The stop arm is used to cooperate with the locking structure disposed on the base when the sliding frame moves, so as to lock or unlock the sliding frame.

[0007] This technical solution provides a specific method for implementing a locking mechanism, ensuring stable locking and reliable unlocking of the sliding frame.

[0008] More specifically, in some embodiments, the base is provided with a toggle ramp and a locking groove; when the sliding frame moves to the locking position for the first time, the stop arm is driven by the toggle ramp and engages in the locking groove; when the sliding frame moves for the second time, the stop arm disengages from the locking groove.

[0009] This technical solution enables a push-type operation of the locking mechanism, that is, a cycle of locking and unlocking is achieved by pushing twice.

[0010] Preferably, the locking mechanism includes: a locking hook; a hinge arm, one end of which is rotatably connected to the sliding frame; and a rotating shaft, which rotatably connects the locking hook to the other end of the hinge arm.

[0011] This technical solution provides a specific locking mechanism structure that ensures reliable locking when cables are inserted.

[0012] Furthermore, the locking mechanism is provided with an inclined guide groove, and the locking hook slides along the inclined guide groove to the top when the sliding frame moves, so as to deflect and engage with the cable.

[0013] This technical solution enables the automatic deflection and locking of the locking hook during the movement of the sliding frame.

[0014] Preferably, the locking mechanism further includes a pad disposed on the hinge arm, the pad being used to support the locking hook.

[0015] This technical solution can enhance the stability of the locking hook.

[0016] Furthermore, the sliding frame is provided with a slider, and the base is provided with a groove that mates with the slider.

[0017] This technical solution ensures that the sliding frame slides smoothly and precisely on the base.

[0018] Preferably, it also includes a first locking post and a second locking post for guiding the spring.

[0019] This technical solution can effectively guide the spring's reset movement and prevent the spring from deflecting or jamming.

[0020] This utility model discloses a flexible electrical connection structure, which is disposed on the terminal block and is used to electrically connect with the cable when it is inserted.

[0021] This technical solution enables a reliable electrical connection when the cable is inserted, ensuring stable transmission of signals and power.

[0022] More specifically, the cable end has a groove, and the locking hook engages in the groove.

[0023] This technical solution enables a more secure connection between the locking hook and the cable, preventing accidental detachment.

[0024] The headband cable assembly disclosed in this utility model provides an innovative solution to the problems of inconvenient cable connection and plugging operations, easy cable damage, and insufficient reliability in the prior art.

[0025] Specifically, while the fixed welding structure commonly used in existing technologies provides stable connections, its non-removable nature or difficulty in disassembly severely limits cable replacement and equipment maintenance and upgrades. Magnetic or snap-on connections, while offering some convenience, often require users to pull the cable itself out, which, with prolonged and frequent use, can easily damage the internal structure, wear down the outer sheath, or even break the cable, significantly shortening its lifespan and potentially causing electrical faults such as poor contact.

[0026] This invention achieves a push-to-connect and unlock mechanism for cables by introducing a base, sliding bracket, locking mechanism, spring, and locking mechanism working together. When the cable is inserted and pushes the sliding bracket to the locked position, the locking mechanism automatically locks the sliding bracket, thus securely holding the cable within the assembly. When it is necessary to disconnect, the user only needs to push the cable again, and the locking mechanism will release the sliding bracket. Driven by the spring, the sliding bracket returns to its original position, and the locking mechanism separates from the cable, allowing for easy cable removal. Attached Figure Description

Detailed Implementation

[0039] While conventional fixed welding structures offer stable connections, their non-removable nature or difficulty in disassembly severely limits cable replacement and equipment maintenance and upgrades. Magnetic or snap-on connections, though convenient, often require users to pull the cable itself out, which, with prolonged and frequent use, can easily damage the internal structure, wear down the outer sheath, or even break, significantly shortening cable lifespan and potentially causing electrical faults such as poor contact.

[0040] This invention achieves a push-to-connect and unlock mechanism for cables by introducing the coordinated operation of a base 38, a sliding bracket 31, a locking mechanism 39, a spring 35, and a locking mechanism. When the cable is inserted and pushes the sliding bracket 31 to the locked position, the locking mechanism automatically locks the sliding bracket 31, thus securely holding the cable within the assembly. When it is necessary to disconnect, the user only needs to push the cable again, and the locking mechanism will release the lock on the sliding bracket 31. Driven by the spring 35, the sliding bracket 31 returns to its original position, and the locking mechanism 39 separates from the cable, enabling convenient cable removal.

[0041] Therefore, in order to improve the problems in the related technology, the embodiments of this application provide the following solutions:

[0042] Optionally, in some embodiments, please refer to Figures 1 to 2 This application provides a headband cable assembly, including: a base 38; a sliding frame 31, which is movably disposed on the base 38; a locking mechanism 39, which is disposed within the sliding frame 31 and is used to engage with the cable 4 when the cable 4 is inserted; a spring 35, which is disposed between the base 38 and the sliding frame 31 and is used to drive the sliding frame 31 to reset when the sliding frame 31 is unlocked; and a locking mechanism, which is used to lock the sliding frame 31 when the cable 4 pushes the sliding frame 31 to the locked position, and to release the lock on the sliding frame 31 when the cable 4 pushes the sliding frame 31 again.

[0043] It is understandable that the sliding bracket 31 is a structural component that can slide back and forth in the base 38, which is used to drive the locking mechanism 39 to achieve the locking and ejection of the cable after insertion.

[0044] It can be understood that the locking mechanism 39 is a structure installed in the sliding frame 31, including components such as the locking hook 393, which can engage with the cable end groove 41 under the movement of the sliding frame 31 to achieve mechanical fixation of the cable.

[0045] It is understandable that the user inserts the cable into the component, and the front end of the cable pushes the sliding bracket 31 to move within the base 38.

[0046] As the sliding frame 31 moves, the locking mechanism 39 moves accordingly to engage with the cable; when the sliding frame 31 moves to the locking position, the locking mechanism automatically locks it.

[0047] The user pushes the cable again, and the sliding bracket 31 continues to move, triggering the locking mechanism to unlock; then, the spring 35 releases its elastic force, driving the sliding bracket 31 back to its initial position.

[0048] In some embodiments, please refer to Figures 3 to 10 The locking mechanism includes a stop arm 37 and a diamond block 36 disposed on the sliding frame 31. The stop arm 37 is used to cooperate with the locking structure disposed on the base 38 when the sliding frame 31 moves, so as to lock or unlock the sliding frame 31.

[0049] It can be understood that the stop arm 37 refers to the structural component set on the sliding frame 31, which is used to cooperate with the locking structure on the base 38 during the movement of the sliding frame 31 to realize the mechanical locking or unlocking of the sliding frame 31.

[0050] It is understandable that the diamond block 36 refers to the auxiliary structure set on the sliding frame 31, which is usually used to guide or restrict the movement of the stop arm 37.

[0051] It can be understood that the locking structure refers to the mechanism part set on the base 38, which can be matched with the stop arm 37 in shape or structural design to restrict or release the position of the sliding frame 31.

[0052] When the sliding frame 31 moves along the base 38, the stop arm 37 moves with the sliding frame 31. When the sliding frame 31 reaches a specific position, the stop arm 37 engages with the locking structure on the base 38, thereby locking the sliding frame 31 at that position and preventing it from rebounding. When the sliding frame 31 continues to move to another preset position, the engagement between the stop arm 37 and the locking structure is released, unlocking the sliding frame 31 and allowing it to reset.

[0053] In some embodiments, please refer to Figures 3 to 10 The base 38 is provided with a toggle ramp and a locking groove; when the sliding frame 31 moves to the locking position for the first time, the stop arm 37 is driven by the toggle ramp and gets into the locking groove; when the sliding frame 31 moves for the second time, the stop arm 37 disengages from the locking groove.

[0054] It is understood that the inclined surface refers to the inclined surface structure set on the base 38. When the stop arm 37 contacts and slides over the inclined surface, its posture or position will be guided or changed to trigger the locking action.

[0055] It can be understood that the locking groove is a groove 41 structure set on the base 38, which is used to make the stop arm 37 snap into place and complete the locking after being guided by the inclined surface.

[0056] It is understandable that the first movement refers to the movement of the sliding frame 31 from the initial position to the locked position when it is first pushed by the cable.

[0057] It is understandable that the second movement refers to the sliding bracket 31 moving further inward from the locked position when it is pushed by the cable again, triggering the unlocking process.

[0058] Specifically, the sliding frame 31 is initially pushed forward; the stop arm 37, driven by the sliding frame 31, contacts the actuating inclined surface on the base 38; under the action of the actuating inclined surface, the stop arm 37 deflects or compresses, eventually locking into the locking groove, thus locking the sliding frame 31. The sliding frame 31 is then pushed again by the cable; the stop arm 37 is released or slips out under the action of the locking groove; the sliding frame 31 loses its locking constraint and becomes resettable.

[0059] In some embodiments, please refer to Figures 3 to 10 The locking mechanism 39 includes: a locking hook 393; a hinge arm, one end of which is fixed to the sliding frame 31; and a rotating shaft 391, one end of which is rotatably connected to the locking hook 393 and the other end of which is fitted into the hole at the end of the hinge arm.

[0060] It is understandable that the locking hook 393 refers to a rotatable hook-shaped component, which is the actuator that actually engages with the cable.

[0061] It can be understood that the hinge arm 392 refers to a structure where one end is fixedly connected to the sliding frame 31 and the other end has a hole, serving as a support structure for the pivot 391.

[0062] It can be understood that the pivot 391 refers to the pivot that is rotatably connected to the locking hook 393 at one end and inserted into the hole of the hinge arm at the other end, so as to realize the rotatable support and guidance of the locking hook 393.

[0063] Specifically, the hinge arm is fixed to the sliding frame 31, providing basic support for the locking mechanism 39; the locking hook 393 is connected to the hinge arm via the pivot 391, forming a rotatable linkage structure. When the sliding frame 31 moves during cable insertion, it drives the locking hook 393 to move as a whole; the locking hook 393 deflects at the pivot point of the pivot 391, achieving engagement and locking with the cable.

[0064] In some embodiments, please refer to Figures 3 to 10 The locking mechanism 39 is provided with an inclined guide groove. When the sliding frame 31 moves, the locking hook 393 slides along the inclined guide groove to the top to deflect and engage with the cable 4.

[0065] It can be understood that the inclined guide groove refers to the guide structure set on the locking mechanism 39, which is inclined at an angle and is used to guide the running path of the locking hook 393 during the movement of the sliding frame 31.

[0066] It can be understood that sliding to the top means that the locking hook 393 moves upward or along the direction of the guide groove to the preset end position under the guidance of the inclined guide groove.

[0067] Specifically, the sliding bracket 31 is pushed by the cable to move along the direction of the base 38; the locking hook 393 slides obliquely under the constraint of the oblique guide groove; during the process of sliding to the top of the guide groove, the locking hook 393 deflects. After deflection, the locking hook 393 comes into contact with or inserts into the preset groove 41 on the cable; the cable is securely locked through mechanical engagement.

[0068] In some embodiments, please refer to Figures 3 to 10 The locking mechanism 39 also includes a pad 394 disposed on the hinge arm 392, which is used to support the locking hook 393.

[0069] It is understandable that the pad 394 refers to the structural component installed on the hinge arm 392, which is used to provide support for the locking hook 393 and prevent it from sagging, swinging, or being deformed due to force, thus affecting its function.

[0070] It is understandable that the support finger provides stable support in the structure, so that the locking hook 393 maintains the preset posture and improves its stability and reliability during operation.

[0071] Specifically, the pad 394 is fixed on the hinge arm and located below or at a related position of the locking hook 393, forming the support surface of the locking hook 393. When the sliding frame 31 moves and drives the locking mechanism 39 to move, the locking hook 393 is always supported by the pad 394 during the rotation process, maintaining a stable deflection trajectory and not shaking or deforming.

[0072] In some embodiments, please refer to Figures 3 to 10 The sliding frame 31 is provided with a slider 32, and the base 38 is provided with a groove that cooperates with the slider 32.

[0073] It can be understood that slider 32 refers to a protruding structure or guide component set on sliding frame 31, which is used to cooperate with the sliding groove on base 38 during sliding to guide the sliding path.

[0074] The sliding frame 31 is inserted into the groove on the base 38 via the slider 32 thereon, forming a slidable connection. When the sliding frame 31 is pushed by an external force, the slider 32 slides along the groove, causing the entire sliding frame 31 to move along a predetermined straight line or guide trajectory, thereby driving the locking mechanism 39 to perform the insertion and removal action.

[0075] In some embodiments, please refer to Figures 3 to 10 It includes a flexible electrical connection structure 2, which is disposed within the base 38 and is used to electrically connect with the cable 4 when it is inserted.

[0076] It can be understood that the flexible electrical connection structure 2 refers to an electrical contact device with elastic function set inside the base 38, which can automatically contact the conductor and form an electrical connection when the structure contacts.

[0077] When the cable is inserted, the flexible electrical connection structure 2 automatically contacts the conductive part at the front end of the cable, and completes the electrical connection during the process of compression or elastic deformation.

[0078] In some embodiments, please refer to Figures 3 to 10 The end of the cable 4 is provided with a groove 41, and the locking hook 393 is engaged in the groove 41.

[0079] It can be understood that the groove 41 refers to the recessed structure set at the end of the cable 4, which is used to provide an engagement part with the locking hook 393 to achieve mechanical locking.

[0080] It is understandable that the locking hook 393 enters and embeds into the cable groove 41 to fix the cable in place after insertion.

[0081] When the locking hook 393 is deflected and slides into the groove 41 provided at the end of the cable under the movement of the sliding frame 31, mechanical locking is achieved to prevent the cable from loosening.
