Description

Technical Field

[0001] This application relates to the field of terminal wire technology, and more particularly to a terminal wire designed to prevent detachment. Background Technology

[0002] Terminal wires are cables that connect electrical components (such as motors, sensors, switches, etc.) to power sources or other circuit types. They typically consist of a conductor, an insulation layer, and an outer sheath, and have good conductivity, corrosion resistance, and mechanical strength. Their main functions include transmitting current and signals, as well as providing a safe and reliable electrical connection.

[0003] Referring to Chinese patent application CN219959557U, an anti-detachment wire harness terminal is disclosed, comprising a terminal body and a connecting wire harness. An anti-detachment mechanism is connected to one side of the terminal body where the connecting wire harness is installed. The anti-detachment mechanism includes a lower bar and an upper bar. One side of the lower bar is fixedly connected to one side of the terminal body, and one end of the upper bar is rotatably connected to one end of the lower bar, with the other end snapped in place. Multiple slots matching the connecting wire harness are provided on adjacent sides of the upper and lower bars. This utility model achieves restriction of the connecting wire harness by fixing the anti-detachment mechanism to one side of the terminal body, and the upper and lower bars in the anti-detachment mechanism clamp the connecting wire harness, thereby preventing the connecting wire harness from detaching from the terminal body. The overall structure is simple and easy to use, and it can increase the stability of the terminal body and the connecting wire harness for power, signal, and other transmissions.

[0004] However, the existing terminal wires commonly used in the technology have relatively simple structures and functions, which makes them prone to falling off after repeated plugging and unplugging, thus affecting subsequent data transmission and causing unstable signal transmission. To address this, we have designed a terminal wire that prevents falling off. Utility Model Content

[0005] The terminal wire provided in this application embodiment can solve the technical problem that the terminal wire has a relatively simple structure and function, and therefore the terminal wire is prone to falling off after repeated plugging and unplugging, which affects the subsequent data transmission and causes unstable signal transmission.

[0006] This application provides an anti-detachment terminal wire including a terminal wire, a terminal base, and a wiring terminal. The terminal base is fixedly connected to one end of the terminal wire, and the wiring terminal is fixedly connected to the other end of the terminal wire. The wiring terminal is provided with an anti-detachment mechanism, which includes a mounting shell, a pressing plate, a limiting plate, and an anti-detachment component. The mounting shell is fixedly mounted on the wiring terminal, and a limiting groove is formed on the top front end of the mounting shell. The pressing plate is disposed above the limiting groove, and the limiting plate is disposed inside the limiting groove and abuts against the inner wall of the limiting groove. The bottom of the pressing plate is fixedly connected to the upper surface of the limiting plate, and the pressing plate and the limiting plate are slidably connected up and down in the limiting groove. The anti-detachment component is used to fix the terminal wire to be connected in an anti-detachment manner.

[0007] The technical solutions described in this application embodiment have at least the following technical effects:

[0008] 1. This application incorporates an anti-detachment mechanism, which allows the user to push the pressing plate downwards after other terminal wires are inserted into the device's terminals. This causes the compression spring at the bottom of the pressing plate to press and push the circular plate into the circular hole, thus pressing and fixing the insertion post of the terminal wire. This prevents the terminal wire from becoming severely worn and deformed after repeated insertion and removal, which could lead to the terminal wire falling off.

[0009] 2. This application sets up a movable block to slide the plug of the device in a movable groove in the terminal block. When not in use, the plug of the device can be moved into the terminal block for hidden protection, thereby preventing the plug from being damaged by impact with the ground when it accidentally falls with the terminal wire, which would affect the normal use of the terminal wire. At the same time, it can also reduce the friction on the surface of the plug, improve the stability and conductivity of its data transmission, and extend its service life.

[0010] In some embodiments, the shape and size of the limiting plate are larger than the opening size of the limiting groove.

[0011] In some embodiments, the anti-detachment component includes a plurality of compression springs and a plurality of circular pressure plates. One end of the plurality of compression springs is uniformly fixedly connected to the bottom of the limiting plate, and the plurality of circular pressure plates are respectively fixedly connected to the ends of the plurality of compression springs away from the limiting plate.

[0012] In some embodiments, a receiving block is further provided inside the mounting shell. The upper surface of the receiving block is uniformly provided with a plurality of circular holes. The front end of the mounting shell is provided with a plurality of insertion holes. The plurality of insertion holes communicate with the plurality of circular holes, and the plurality of insertion holes and the plurality of circular holes are integrally formed.

[0013] In some embodiments, the size of the plurality of circular holes corresponds to the size of the plurality of circular pressure plates.

[0014] In some embodiments, a groove is provided on the upper surface of the pressing plate, and a sliding plate is slidably connected inside the groove. A through hole is also provided on one side wall of the pressing plate, which communicates with the groove. A limiting post is slidably connected inside the through hole, and one end of the limiting post is fixedly connected to the bottom of the sliding plate.

[0015] In some embodiments, the terminal block has a movable groove inside, a movable block is slidably connected in the movable groove, and a plurality of plug pins are fixedly installed at one end of the movable block. Attached Figure Description

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] Based on this, in order to improve the relatively simple structure and function of the terminal wires in the related technologies, which makes the terminal wires prone to falling off after repeated plugging and unplugging, thus affecting the subsequent data transmission and causing unstable signal transmission, the embodiments of this application provide the following solutions.

[0025] Please see Figures 1 to 5 A terminal wire 1 designed to prevent detachment includes a terminal wire 1, a terminal base 2, a wiring terminal 3, and an anti-detachment mechanism 4. The terminal wire 1 is used for data transmission, the terminal base 2 is used for supporting and protecting the plug-in post 15, and the anti-detachment mechanism 4 is used to prevent the terminal wire 1 from easily detaching after repeated plugging and unplugging.

[0026] Please see Figures 1 to 4 The terminal block 2 is fixedly connected to one end of the terminal wire 1, and the terminal 3 is fixedly connected to the other end of the terminal wire 1. The terminal 3 is provided with an anti-detachment mechanism 4, which includes a mounting shell 41, a pressing plate 42, a limiting plate 43, and an anti-detachment component 44. The mounting shell 41 is fixedly mounted on the terminal 3. A limiting groove 5 is formed on the top front end of the mounting shell 41. The pressing plate 42 is positioned above the limiting groove 5. The limiting plate 43 is positioned inside the limiting groove 5 and abuts against the inner wall of the limiting groove 5. The bottom of the pressing plate 42 is fixedly connected to the upper surface of the limiting plate 43, and the pressing plate 42 and the limiting plate 43 are slidably connected vertically within the limiting groove 5. The shape and size of the limiting plate 43 are larger than the limiting groove 5. The anti-detachment component 44 includes multiple compression springs 441 and multiple circular pressure plates 442. One end of each compression spring 441 is uniformly fixed to the bottom of the limiting plate 43. The multiple circular pressure plates 442 are respectively fixed to the ends of the compression springs 441 away from the limiting plate 43. A receiving block 6 is also provided inside the mounting shell 41. Multiple circular holes 7 are uniformly opened on the upper surface of the receiving block 6. Multiple insertion holes 8 are opened at the front end of the mounting shell 41. The insertion holes 8 communicate with the multiple circular holes 7 and are integrally formed with the insertion holes 8 and the multiple circular holes 7. The size of the multiple circular holes 7 corresponds to the size of the multiple circular pressure plates 442.

[0027] With this setup, when data transmission is required for terminal line 1, the plug 15 is first inserted into the circular hole 7 through the plug hole 8. At this time, the user pushes the pressing plate 42 downwards, causing it to move downwards. Simultaneously, the compression spring 441 located below the pressing plate 42 drives the circular pressing plate 442 downwards, compressing and fixing the plug 15 inserted into the circular hole 7. During the compression and fixing process, the compression spring 441 will contract downwards and deform. After the plug 15 inside the circular hole 7 is compressed and fixed according to its size, the user stops pushing the pressing plate 42. At this time, the user pushes the sliding plate 10 located on the upper surface of the pressing plate 42 along the square groove 9. The bottom of the sliding plate 10 drives the limiting post 12 to move along the direction of the sliding groove 9, so that one end of the limiting post 12 passes through the through hole 11 and is located outside the through hole 11. Then, the pressing plate 42 is released, and under the reverse force given by the compression spring 441, the limiting post 12 abuts against the inner wall of the mounting shell 41, thereby completing the fixation of the circular pressing plate 442. When it is necessary to pull out the plug post 15 of the circular hole 7, the sliding plate 10 is pushed in the opposite direction, so that the limiting post 12 returns to its original position in the opposite direction. Then, under the force of the compression spring 441 to restore the original state, the pressing plate 42 carries the circular pressing plate 442 back to its original position. At the same time, under the action of the limiting plate 43, the bottom of the pressing plate 42 will not be ejected from the limiting groove 5.

[0028] The effect of this setting is that, by setting the anti-disconnection mechanism 4, after other terminal wires 1 are inserted into the wiring terminal 3 of the device, the user can push the pressing plate 42 downwards, so that the compression spring 441 at the bottom of the pressing plate 42 is squeezed and pushed into the circular hole 7, thereby squeezing and fixing the plug post 15 of the inserted terminal wire 1. This prevents the wiring terminal 3 of the device from being severely worn and deformed after repeated insertion and removal, which would make the terminal wire 1 easy to fall off.

[0029] Optionally, please refer to Figure 1 and Figure 5 The terminal block 2 has a movable groove 13 inside, and a movable block 14 is slidably connected in the movable groove 13. A plurality of plug-in pins 15 are fixedly installed at one end of the movable block 14.

[0030] With this configuration, when a plug-in post is required for connection, the user pushes the movable block 14 to slide within the movable slot 13, causing the plug-in post 15 on the movable block 14 to protrude from the terminal block 2. Simultaneously, during the insertion of the plug-in post 15, the user touches the end of the movable block 14 away from the plug-in post 15 with their hand, thereby completing the connection.

[0031] The effect of this design is that by setting the moving block 14 to slide the plug 15 of the device within the moving groove 13 in the terminal block 2, the plug 15 can be moved into the terminal block 2 for concealment and protection when not in use. This prevents the plug 15 from being damaged by impact with the ground when it accidentally falls with the terminal wire 1, thus affecting the normal use of the terminal wire 1. At the same time, it can also reduce the friction on the surface of the plug 15, improve the stability and conductivity of its data transmission, and extend its service life.

[0032] As can be seen from the above, the working principle of this application is as follows:

[0033] When data transmission is required from terminal line 1, the plug 15 is first inserted into the circular hole 7 through the plug hole 8. At this time, the user pushes the pressing plate 42 downwards, causing it to move downwards. Simultaneously, the compression spring 441 located below the pressing plate 42 drives the circular pressing plate 442 downwards, compressing and fixing the plug 15 inserted into the circular hole 7. During this compression and fixing process, the compression spring 441 contracts downwards, deforming. After the plug 15 inside the circular hole 7 is compressed and fixed according to its size, the user stops pushing the pressing plate 42. Then, the user pushes the sliding plate 10 located on the upper surface of the pressing plate 42 along the sliding groove 9, causing the sliding plate to... The bottom of the moving plate 10 drives the limiting post 12 to move along the direction of the sliding groove 9, so that one end of the limiting post 12 passes through the through hole 11 and is located outside the through hole 11. Then the pressing plate 42 is released. Under the reverse force of the compression spring 441, the limiting post 12 abuts against the inner wall of the mounting shell 41, thereby completing the fixation of the circular pressing plate 442. When it is necessary to pull out the plug post 15 of the circular hole 7, the sliding plate 10 is pushed in the opposite direction, so that the limiting post 12 returns to its original position in the opposite direction. Then, under the force of the compression spring 441 to restore the original state, the pressing plate 42 carries the circular pressing plate 442 back to its original position. At the same time, under the action of the limiting plate 43, the bottom of the pressing plate 42 will not be ejected from the limiting groove 5.

[0034] When a plug-in post is required, the user slides the movable block 14 in the movable slot 13, so that the plug post 15 on the movable block 14 is exposed in the terminal block 2. At the same time, during the plugging process, the user touches the end of the movable block 14 away from the plug post 15 with his hand to complete the plugging.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
