Description

Technical Field

[0001] This utility model relates to the field of power plug technology, specifically to a multi-directional plug pin of a power plug. Background Technology

[0002] The two-prong plug can be rotated to engage with the socket, allowing it to be plugged into both two-prong and three-prong sockets, offering greater flexibility. In related technologies, the two-prong plug uses a screw-tightening method to connect the wire. This wiring method is suitable for copper wires, as the flexibility of copper wires does not hinder the rotation of the plug prongs. However, when the wire core is made of copper strips, the copper strips are difficult to rotate. Once connected to the plug prongs, the prongs cannot rotate, and the plug cannot be plugged into a three-prong socket. Utility Model Content

[0003] The purpose of this invention is to provide a multi-directional plug pin for a power plug to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-directional plug pin of a power plug, comprising a first splicing shell, a second splicing shell connected to the first splicing shell, and two inserts rotatably mounted between the first splicing shell and the second splicing shell.

[0005] Two electrical connectors are provided and installed inside the first splicing shell. The two electrical connectors are connected to the two plugs by a spiral line. The spiral line will not affect the rotation of the plugs. The copper strip of the wire is connected to the electrical connector. The copper strip will not affect the rotation of the plugs.

[0006] The limiter is installed on the first splicing shell, the second splicing shell, and the insert to improve the stability of the connection between the insert and the first and second splicing shells, and to prevent the insert from becoming loose.

[0007] Furthermore, the first splicing shell has two threaded tubes inside, and pressure plates are installed on the threaded tubes. The inner wall of the first splicing shell has two extrusion strips, and the extrusion strips are located below the pressure plates. The wire is placed between the extrusion strips and the pressure plates, and the pressure plates are fixed with cross screws, so that the pressure plates and extrusion strips clamp the wire, and the connection between the wire and the first and second splicing shells is stable, and the two are not easy to separate.

[0008] Furthermore, the electrical connector includes a terminal block with a clamping screw screwed onto it. The end of the spiral wire is provided with a connecting ring, which is fitted onto the clamping screw. The copper strip or wire of the wire is connected to the terminal block through the clamping screw, thereby realizing the electrical connection between the wire and the plug, making the wire connection convenient.

[0009] Furthermore, the limiter includes a limit shell and an insulating sleeve. The limiter is disposed on the first splicing shell and the second splicing shell. The insulating sleeve is sleeved on the insert and snaps into the limit shell. The insulating sleeve has a limiting ring. The first splicing shell and the second splicing shell clamp the limiting ring to ensure that the insert rotates stably and will not separate from the first splicing shell and the second splicing shell. The surfaces of the two insulating sleeves are provided with mutually meshing sector gears, and the side of the sector gears is provided with anti-rotation blocks. The synchronous rotation of the insert can be controlled by the sector gears.

[0010] Compared with the prior art, the beneficial effects of this utility model are: after loosening the fixing screws, the first and second splicing shells are opened, the wires are stripped, the clamping screws are loosened and the wires are inserted into the terminal block, and then the clamping screws are tightened to fix the wires. The wires are electrically connected to the plugs through the spiral wires. The spiral wires do not affect the rotation of the plugs, making it convenient for the plug to connect with copper strip wires and copper wires. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Example:

[0019] Please see Figure 1-5 This utility model provides a technical solution: a multi-directional plug pin of a power plug, including a first splicing shell 1, the first splicing shell 1 is connected to a second splicing shell 5, and two inserts 4 are rotatably installed between the first splicing shell 1 and the second splicing shell 5. The inserts 4 can be rotated to change the tilt angle, so as to facilitate the insertion of the inserts 4 into the two-hole and three-hole sockets. The side of the first splicing shell 1 connected to the second splicing shell 5 has anti-slip texture 2, which makes it easy to unplug the plug.

[0020] Two electrical connectors are provided and installed inside the first splicing shell 1. The two electrical connectors are connected to the two plugs 4 by a spiral 13. The spiral 13 can rotate freely and will not affect the rotation of the plugs 4, ensuring that the rotation of the plugs 4 is not affected by the wires.

[0021] The limiter is installed on the first splicing shell 1, the second splicing shell 5, and the insert 4 to ensure that the insert 4 is stably assembled, will not loosen, and rotates more stably.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, both the first splicing shell 1 and the second splicing shell 5 have grooves on their surfaces. The first splicing shell 1 and the second splicing shell 5 are fixed in the grooves by fixing screws 3 and nuts 6. Using two fixing screws 3 and nuts 6 improves the stability of the connection between the first splicing shell 1 and the second splicing shell 5, and also facilitates the disassembly of the first splicing shell 1 and the second splicing shell 5.

[0023] In this embodiment, as Figure 4 As shown, the first splicing shell 1 has two threaded tubes 18 inside, and a wire pressing plate 9 is installed on the threaded tube 18. The wire pressing plate 9 can be fixed by using a cross screw in conjunction with the threaded tube 18. The wire pressing plate 9 can press the outer sheath of the wire, thereby improving the stability of the connection between the wire and the first splicing shell 1.

[0024] In this embodiment, as Figure 4 As shown, the inner wall of the first splicing shell 1 is provided with two extrusion strips 8, and the extrusion strips 8 are located below the wire pressing piece 9. The two extrusion strips 8 can better clamp the wire. When the wire and the first splicing shell 1 are pulled, the first splicing shell 1 and the wire are not easy to separate, thus avoiding the problem of poor contact between the wire and the terminal block 11.

[0025] In this embodiment, as Figure 4 As shown, the electrical connector includes a terminal block 11, on which a clamping screw 12 is screwed. The end of the spiral wire 13 is provided with a connecting ring 14, which is fitted onto the clamping screw 12. The wire is inserted into the terminal block 11 and fixed by the clamping screw 12, making wiring convenient.

[0026] In this embodiment, as Figure 4As shown, the first splicing shell 1 has four limiting posts 10 inside, and the terminal block 11 is sleeved on the surface of the limiting posts 10, which can ensure that the two terminal blocks 11 will not contact each other and will not cause a short circuit.

[0027] In this embodiment, as Figure 4 and Figure 5 As shown, the limiter includes a limiting shell 16 and an insulating sleeve 19. The limiter is mounted on the first splicing shell 1 and the second splicing shell 5. The insulating sleeve 19 is sleeved on the insert 4 and snapped into the limiting shell 16 to realize the installation of the insert 4 and ensure the connection between the insert 4 and the first splicing shell 1 and the second splicing shell 5. The insulating sleeve 19 has a limiting ring 7. The first splicing shell 1 and the second splicing shell 5 clamp the limiting ring 7. After the insert 4 is turned to the designated position, the clamped limiting ring 7 can restrict the rotation of the insert 4 and prevent the insert 4 from rotating freely.

[0028] In this embodiment, as Figure 4 and Figure 5 As shown, the surfaces of the two insulating sleeves 19 are provided with intermeshing sector gears 15, and the side of the sector gears 15 is provided with anti-rotation blocks 17. When one insert 4 is rotated, the other insert 4 is also rotated through the two sector gears 15, which makes it convenient to control the rotation of the insert 4.

[0029] Specifically, in use, after unscrewing the fixing screw 3, separate the first splicing shell 1 and the second splicing shell 5. Then, unscrew the cross screw to remove the wire clamping piece 9, strip the wire insulation to expose the wire core, loosen the clamping screw 12, insert the wire core into the terminal block 11, and then tighten the clamping screw 12 to fix the wire to the terminal block 11. Then, place the wire into the compression strip 8, and use the wire clamping piece 9 in conjunction with the cross screw to fix the wire to the first splicing shell 1. Then, use the fixing screw 3 and nut 6 to fix the first splicing shell 1 and the second splicing shell 5 together. When the plug 4 is rotated, the plug 4 drives the insulating sleeve 19 to rotate. The insulating sleeve 19 controls the rotation of another sector gear 15, the insulating sleeve 19 and the plug 4 through the sector gear 15, so that the two plugs 4 can be smoothly plugged into the two-hole and three-hole sockets.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
