Description

Technical Field

[0001] This utility model relates to the field of line connection technology, specifically to a pluggable terminal block for preventing cable deformation. Background Technology

[0002] Plug-in terminal blocks (also known as anti-deformation terminals) designed to prevent cable deformation are designed to ensure that cables are not subjected to excessive mechanical stress during connection, disconnection, and use, thus avoiding cable deformation, wear, or damage.

[0003] However, some terminal blocks have the following problems when used: if the connection between the terminal block and the external wiring is not firm or the contact surface is unstable, poor contact is likely to occur, resulting in poor current flow or signal loss.

[0004] Secondly, if the terminal block design does not facilitate quick plugging and unplugging, the installation process may be cumbersome, requiring more time and tools.

[0005] Finally, if the terminal block does not provide cable protection, it may cause excessive stress on the cable, resulting in bending or tensile damage, which may affect the cable's performance or cause it to break. Utility Model Content

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5A pluggable terminal block for preventing cable deformation includes a main body 1, an installation mechanism, a fixing component, and auxiliary components. The installation mechanism includes a rotating rod 2, an upper contact plate 3, a lower contact plate 4, a first spring 5, and an external plate 6. The rotating rod 2 is mounted on the main body 1 and rotatably connected to the main body 1. The upper contact plate 3 and the lower contact plate 4 are mounted inside the main body 1 and are threadedly engaged with the first rotating rod 2 and slidably connected to the main body 1, respectively. The first spring 5 is mounted inside the main body 1, and its other end is fixedly connected to the lower contact plate 4. The external plate 6 is fixedly mounted on the main body 1 and slidably connected to the upper contact plate 3 and the lower contact plate 4. The fixing component includes a second spring 7, a fixing member 8, and an external wire 9. The external wire 9 is mounted on the main body 1 and detachably connected to the main body 1. The fixing member 8 is mounted inside the main body 1 and is slidably connected to the main body 1 and engaged with the external wire 9, respectively. The second spring 7 is fixedly mounted inside the main body 1, and its other end is fixedly connected to the fixing member 8.

[0031] In this embodiment, the installation mechanism includes a rotating rod 2, an upper contact plate 3, a lower contact plate 4, a first spring 5, and an outer plate 6. In use, the external wire 9 is inserted into the main body 1. Then, the rotating rod 2 is rotated. Under the action of the bidirectional screw 15 of the rotating rod 2, the threaded holes 13 in the upper contact plate 3 and the lower contact plate 4 are matched with each other, thereby surrounding the end 20 of the external wire 9 with the surrounding piece 12 on the upper contact plate 3 and the lower contact plate 4. When the upper contact plate 3 and the lower contact plate 4 are close to each other, the connectors 16 on the upper contact plate 3 and the lower contact plate 4 slide in the connecting groove 17 of the outer plate 6, and the positioning bracket 14 on the lower contact plate 4 slides on the main body 1 to compress the first spring 5, making it easier to disassemble the external wire 9 from the main body 1. After the end 20 is fixed, the wire can be inserted into the external hole 18 on the outer plate 6, and under the action of the rubber pad 19, the main body 1 is insulated from the outside.

[0032] In this embodiment, the fixing component includes a second spring 7, a fixing member 8, and an external wiring 9. In use, the external wiring 9 is installed in the placement groove 24 of the placement plate 23 of the main body 1. When the external wiring 9 is inserted into the main body 1, the fixing member 8 can be pressed, causing the fixing member 8 installed on the main body 1 to slide inside the main body 1 and compress the second spring 7. When the end 20 contacts the main body 1, the fixing member 8 is released. Under the action of the compressed second spring 7, the locking block 22 on the fixing member 8 engages with the locking hole 21 on the external wiring 9, thereby fixing the external wiring 9. At this time, the cover plate 10 is placed on the external wiring 9, and the fixing bolt 11 is installed between the placement plate 23 and the cover plate 10, thereby fixing the position of the external wiring 9.

[0033] Example 2:

[0034] In summary, during use, the external wiring 9 is first installed in the placement slot 24 of the placement plate 23 of the main body 1. When the external wiring 9 is inserted into the main body 1, the fixing member 8 can be pressed down, causing the fixing member 8 installed on the main body 1 to slide inside the main body 1 and compress the second spring 7. When the end 20 contacts the main body 1, the fixing member 8 is released. Under the action of the compressed second spring 7, the locking block 22 on the fixing member 8 engages with the locking hole 21 on the external wiring 9, thereby fixing the external wiring 9. At this time, the cover plate 10 is placed on the external wiring 9, and the fixing bolt 11 is installed between the placement plate 23 and the cover plate 10, thereby fixing the position of the external wiring 9. After the position of the external wiring 9 is fixed, the main body 1 is electrically connected to the end 20 of the external wiring 9. Then, rotating the rotating rod 2 causes the threaded holes 13 in the upper contact plate 3 and the lower contact plate 4 to engage with each other, thereby surrounding the end 20 of the external wiring 9 with the surrounding piece 12 on the upper contact plate 3 and the lower contact plate 4. When the upper contact plate 3 and the lower contact plate 4 approach each other, the connectors 16 on the upper contact plate 3 and the lower contact plate 4 slide in the connecting grooves 17 of the outer plate 6, and the positioning bracket 14 on the lower contact plate 4 slides on the main body 1 to compress the first spring 5, making it easier to disassemble the external wiring 9 from the main body 1. After the end 20 is fixed, the wire can be inserted into the external hole 18 on the outer plate 6, and the rubber pad 19 insulates the main body 1 from the outside.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
