Abstract
Description
Technical Field
[0001] This utility model relates to the field of telescopic terminal wire technology, and in particular to a terminal wire with a length telescopic structure. Background Technology
[0002] With the continuous development of industrial automation and electronic equipment, the performance requirements for terminal wires are becoming increasingly stringent. Terminal wires with telescopic length structures not only provide flexible length adjustment but also reduce damage to the connecting wires from external impacts through buffer mechanisms, further improving their reliability in complex environments.
[0003] A typical terminal wire with a telescopic structure consists of a connector, a connecting wire, and a locking rod. During use, the connector is securely connected to the external device through its conductive contacts and locking mechanism, ensuring stable transmission of electrical energy or signals. The connecting wire is length-adjustable through a telescopic mechanism to adapt to different usage scenarios. The locking rod secures the connector to the external device through threads or other locking mechanisms to prevent loosening of the connection due to vibration or external force.
[0004] However, in some existing devices, the relative positions of the equipment may change, causing the connecting wires to be excessively stretched, thereby reducing their service life or even causing the connection to break. When the equipment vibrates or is subjected to external impact, the connecting wires cannot be effectively protected and are easily damaged due to excessive stretching. Therefore, a terminal wire with a length telescopic structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a terminal wire with a length telescopic structure, which aims to improve the problem that some existing devices cannot buffer the extended wire, resulting in excessive pulling and damage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A terminal wire with a length telescopic structure includes a mating block, a buffer mechanism on the top of the mating block, a connecting wire fixedly connected to the outer side of the mating block, and a telescopic mechanism on the outside of the connecting wire.
[0008] The telescopic mechanism includes a placement box, which is located outside the connecting line. A rotating disk is rotatably connected to the inner bottom wall of the placement box. A rotating column is fixedly connected to the top of the rotating disk. Support columns are fixedly connected to both sides of the top of the rotating disk. Guide columns are fixedly connected inside the two support columns. A buffer spring is sleeved on the outside of the guide column. A pressure plate is fixedly connected to the outside of the buffer spring. A limit component is fixedly connected to the outside of the rotating column.
[0009] As a further description of the above technical solution:
[0010] The limiting component includes two fixing blocks, which are externally fixedly connected to the outer sides of the rotating column, and cams are rotatably connected to adjacent outer sides of the two fixing blocks.
[0011] As a further description of the above technical solution:
[0012] The buffer mechanism includes two support blocks, which are externally fixedly connected to the top side of the docking block, and internally connected to a movable column.
[0013] As a further description of the above technical solution:
[0014] The two movable columns are fixedly connected to the outside of a connecting rod, and a guide rod is fixedly connected to the adjacent side of the two connecting rods.
[0015] As a further description of the above technical solution:
[0016] The two guide rods are slidably connected to a sliding rod on their outer sides, and the outer side of the sliding rod is located on the outer side close to the connecting line;
[0017] As a further description of the above technical solution:
[0018] A fixing rod is fixedly connected to the outer adjacent side of the two guide rods, and the outer side of the fixing rod is located at the bottom of the sliding rod;
[0019] As a further description of the above technical solution:
[0020] When the rotating column rotates, it can drive the rotating disk to rotate, causing the two supporting columns to rotate accordingly.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the extension and retraction of the connecting wire is achieved by rotating the rotating column to drive the rotating disk. The buffer spring protects the connecting wire from excessive pulling damage during the winding process. The extension length of the connecting wire is precisely controlled by the limiting component to ensure its stability and reliability in different usage scenarios, while enhancing the versatility and applicability of the terminal wire.
[0023] 2. In this utility model, the rotation of the movable column drives the connecting rod and the guide rod to move, so that the sliding rod slides along the guide rod, thereby absorbing and dispersing vibration and impact force, effectively protecting the internal structure of the terminal wire. The fixed rod provides stable support for the connecting wire, preventing the connecting wire from falling off the mating block due to vibration, and enhancing the reliability of the terminal wire in complex environments. This design not only extends the service life of the terminal wire, but also improves its adaptability and stability in various harsh environments. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 2 and Figure 4An embodiment of this utility model is provided: a terminal wire with a length telescopic structure, including a docking block 1, which is designed to dock well with the device. A buffer mechanism 4 is provided on the top of the docking block 1. A connecting wire 2 for transmitting electrical energy signals is fixedly connected to the outer side of the docking block 1. A telescopic mechanism 3 is provided on the outside of the connecting wire 2.
[0032] The telescopic mechanism 3 includes a placement box 31, designed to provide ample placement space. The placement box 31 is positioned outside the connecting line 2. A rotating disk 32 is rotatably connected to the inner bottom wall of the placement box 31, providing good rotational capability and support for the connecting line 2. A rotating column 33 is fixedly connected to the top of the rotating disk 32, also providing good rotational capability. Support columns 34 are fixedly connected to both sides of the top of the rotating disk 32, providing dual support. During use, the connecting line 2 forms an "S" shape, winding around the outside of the two support columns 34. This allows the door to retract and extend the connecting line 2 when the rotating disk 32 is rotated by the rotating column 33. Guide columns 35 are fixedly connected inside the two support columns 34, providing good guiding capability. A buffer spring 36 is sleeved on the outside of the guide column 35, providing good buffering capability and compressing upon application of force. After the applied force is released, it can rebound. The buffer spring 36 is externally fixedly connected to the pressure plate 37, which is designed to provide good support, allowing the connecting wire 2 to be wound around the outside of the pressure plate 37. At the same time, under the action of the buffer spring 36, the connecting wire 2 can be well buffered during winding, preventing excessive damage to the connecting wire 2. The rotating column 33 is externally fixedly connected to the limit component, which includes two fixing blocks 38. The limit component is designed to provide good support. The two fixing blocks 38 are externally fixedly connected to the two sides of the rotating column 33. The two adjacent sides of the two fixing blocks 38 are rotatably connected to the cam 39, which is designed to rotate smoothly. At the same time, the rotation of the cam 39 is non-central rotation, so that the convex surface of the cam 39 can fix the top of the placement box 31, which can provide good limit control for the extension of the connecting wire 2. When the rotating column 33 rotates, it can drive the rotating disk 32 to rotate, so that the two support columns 34 rotate accordingly.
[0033] Reference Figure 1 and Figure 3The buffer mechanism 4 includes two support blocks 41, designed to provide good support capacity. The two support blocks 41 are externally fixedly connected to the top side of the docking block 1. Movable columns 42 are rotatably connected internally to the two support blocks 41, allowing the movable columns 42 to rotate smoothly thanks to the support of the support blocks 41. Connecting rods 43 are externally fixedly connected to the two movable columns 42, designed to provide good connection and support capacity. Guide rods 44 are fixedly connected to adjacent external sides of the two connecting rods 43, designed to provide good sliding guidance capability. The external sliding connection is a sliding rod 45, which can slide smoothly through the guide rod 44. The outer side of the sliding rod 45 is located close to the outer side of the connecting line 2. The outer adjacent sides of the two guide rods 44 are fixedly connected to a fixed rod 46, which provides good support so that the connecting line 2 is placed between the sliding rod 45 and the fixed rod 46. When vibrating, the movable column 42 will rotate, which will drive the connecting rod 43 to rotate, preventing the connecting line 2 from falling off the docking block 1. The outer side of the fixed rod 46 is located at the bottom of the sliding rod 45.
[0034] Working Principle: When using the terminal wire, if the connecting wire 2 needs to be extended or retracted, rotating the rotating column 33 will cause the rotating disk 32 to rotate. Since the connecting wire 2 is wrapped around the outside of the two support columns 34 in an "S" shape, the connecting wire 2 will be wound or extended accordingly as the rotating disk 32 rotates. During the winding process, the connecting wire 2 will be wound around the outside of the pressure plate 37. At this time, the buffer spring 36 will play its buffering role to prevent the connecting wire 2 from being damaged by excessive tension during the winding process. When the connecting wire 2 is extended to the required length, the extension of the connecting wire 2 is limited by operating the limiting component. Specifically, by rotating the cam 39, since the rotation of the cam 39 is non-central, its convex surface can contact the top of the placement box 31 and generate pressure, thereby fixing the placement box 31, thus controlling the extension length of the connecting wire 2 and keeping it at the required length position.
[0035] When the equipment vibrates or is impacted by external forces, the buffer mechanism 4 activates. At this time, the movable column 42 rotates under the support of the support block 41. Since the movable column 42 is fixedly connected to the connecting rod 43, the connecting rod 43 rotates accordingly. The rotation of the connecting rod 43 drives the guide rod 44 to move, and the guide rod 44 is slidably connected to the sliding rod 45. Therefore, the sliding rod 45 slides under the guidance of the guide rod 44. This sliding motion absorbs and disperses vibration or impact forces, thus providing a buffering effect. Simultaneously, the connecting wire 2 is placed between the sliding rod 45 and the fixed rod 46. The fixed rod 46 provides stable support for the connecting wire 2, preventing it from detaching from the mating block 1 due to vibration. Through the coordinated operation of this buffer mechanism 4, the stability and reliability of the terminal wires under vibration or impact environments can be effectively protected.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
