Description

Technical Field

[0001] The present application relates to the technical field of wiring terminals, and in particular to an anti-dropping wiring terminal. Background Art

[0002] Terminal blocks are commonly used for circuit connection in electronic or electrical equipment. Among them, the fence-type terminal block is designed like a small fence. The wires can be fixed together through the holes or clips on the fence to form a reliable electrical connection.

[0003] After searching, the announcement number is CN218940215U, which discloses an anti-dropping terminal, including multiple fences arranged side by side, and fence bottom plates and fence top plates are provided on both sides of the multiple fences, and the fence top plates are arranged on the fence bottom plates. The anti-dropping terminal also includes a first fixing part, a second fixing part, a cover plate, a first reinforcing screw, a second reinforcing screw, and an elastic block. The first fixing part and the second fixing part are fixed to the outermost fence bottom plate and the fence top plate. The cover plate covers the tops of multiple fences and the first fixing part and the second fixing part. The first reinforcing screw is arranged in a screw hole that penetrates the cover plate and penetrates into the first fixing part, and the second reinforcing screw is arranged in a screw hole that penetrates the cover plate and penetrates into the second fixing part. There are multiple elastic blocks, and multiple elastic blocks are fixed in the fence on the inner side of the cover plate. The cover plate and the elastic block prevent the screws in the fence from loosening, thereby ensuring the stable operation of the equipment.

[0004] However, although the existing fence-type terminal blocks have an anti-falling structure design, in order to prevent the wires from falling off or being stripped from the terminal blocks, the method often adopted is to use other fasteners to re-tighten the screws on the fence-type terminal blocks to prevent the screws from loosening from the threaded holes, thereby providing better fixation for the wires. However, this method will also cause inconvenience when installing and removing the wires, and will also make the use of the fence-type terminal blocks more cumbersome, thereby affecting the equipment construction time.

[0005] Therefore, it is necessary to provide a kind of anti-falling terminal to solve the above-mentioned problem.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0035] See also Figure 1-5 , the utility model provides embodiments:

[0036] An anti-dropping terminal comprises a fence terminal block 1. The top surface of the fence terminal block 1 is threadedly connected with a screw 11 for fixing a wire. The wire inserted is tightened by the screw 11 to fix the wire on the fence terminal block 1.

[0037] One side of the fence wiring seat 1 is rotatably connected to the limiting mechanism 2, and the bottom surface of the limiting mechanism 2 is fixedly connected with a pressure column 5 for limiting the loosening of the screw 11. The limiting mechanism 2 includes a pressing plate 21, a rotating plate 22 and a rotating hole 23. The rotating plate 22 is integrally formed on one side of the pressing plate 21, and the rotating hole 23 is penetrated and opened on the side wall of the rotating plate 22. One side of the fence wiring seat 1 is fixedly connected with a shaft column 12, and the side wall of the shaft column 12 is rotatably connected to the inside of the rotating hole 23. The bottom surface of the pressure column 5 is provided with a truncated cone groove 51;

[0038] Specifically, by rotating the pressure plate 21, the rotating hole 23 on the rotating plate 22 can rotate on the shaft column 12, and the pressure plate 21 can be opened and closed, so that the conical groove 51 on the pressure column 5 can squeeze or release the squeeze state of the screw 11, and the conical groove 51 structure can better and more effectively prevent the screw 11 from loosening when fixing the wire.

[0039] The other side of the fence wiring seat 1 is fixedly connected with a locking mechanism 3, which includes a locking frame 31, a mounting groove 32, a limiting spring piece 33 and a notch 34. The locking frame 31 is fixedly connected to the side wall of the other side of the fence wiring seat 1, the mounting groove 32 is opened on the inside of the locking frame 31, the end of the limiting spring piece 33 is installed in the mounting groove 32, and the bottom side wall of the locking frame 31 is opened with a notch 34;

[0040] The limiting mechanism 2 includes a locking tongue 24 , the bottom end of which is engaged with the bottom surface of the limiting spring piece 33 .

[0041] The limiting spring piece 33 includes an inserting portion, a bending portion, a horizontal portion and an inner folding portion. The inserting portion is fixedly installed in the installation groove 32, one end of the bending portion is integrally formed with the inserting portion, and the other end of the bending portion is integrally formed with the horizontal portion. The tail end of the horizontal portion is connected to the inner folding portion. The bending portion has an inclined structure, and a barb structure is provided on one side of the bottom end of the locking tongue 24.

[0042] When in use, when the pressure plate 21 is rotated to be nearly parallel to the fence wiring seat 1, the lock tongue 24 enters the lock frame 31, and then the pressure plate 21 is continuously rotated to be parallel to the fence wiring seat, so that the hook of the lock tongue 24 slides on the surface of the bent portion, and at the same time, the limiting spring piece 33 as a whole will undergo elastic deformation until it is placed under the horizontal portion and the whole is reset. At this time, the hook structure of the lock tongue 24 is restricted by the limiting spring piece 33 and cannot move upward from below the horizontal portion, so that the pressure plate 21 can remain horizontal, and the internal pressure column 5 can be firmly pressed on the surface of the screw 11.

[0043] An unlocking mechanism 4 is arranged inside the lock frame 31, and the unlocking mechanism 4 includes a pressing plate 41, a sliding plate 42, a limiting block 43 and a limiting plate 44. The top end of the sliding plate 42 is fixedly connected to the pressing plate 41, and the bottom end of the sliding plate 42 is fixedly connected to the limiting plate 44. The limiting blocks 43 are respectively fixedly connected to the inner side walls of the lock frame 31, and the two limiting blocks 43 are slidably connected to the sliding plate 42.

[0044] When it is necessary to remove the pressure plate 21 from above the screw 11 to facilitate the loosening of the screw 11 and the installation and removal of the wire, the pressure plate 41 is pressed to make the slide plate 42 slide downward between the limit blocks 43, so that the limit plate 44 can slide on the surface of the bent portion of the limit spring 33 again, so that the horizontal portion and the barb at the bottom end of the lock tongue 24 are misaligned, so that the lock tongue 24 can move out of the lock frame 31, so that the pressure plate 21 can be opened, and the pressure column 5 can be separated from the screw 11, so that it is convenient to loosen the screw 11 and install and remove the wire.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
