[0002] Electrical connection devices are devices used to establish electrical connections between different electrical components, equipment or systems to ensure smooth conduction of current. Plugs and sockets are common devices in electrical connections, which are used to achieve electrical connections between power sources and equipment. Plugs are usually connected to power sources, and a cable that matches the socket is fixed at one end of the plug, while the socket is used to connect electrical equipment or appliances to provide safe and stable current transmission.

[0003] The existing plug and socket are connected by a cable. When connected, the two ends of the cable are respectively fixed to the plug or socket by bolts. When disassembling and replacing the cable, multiple bolts need to be disassembled and assembled by tools, which is troublesome and time-consuming to maintain, and there is also a risk of bolts being lost. In addition, if the rotation directions of the plug and the socket are opposite after connection, the cable itself will be twisted and torsion. The large twisting force will cause the cable to be entangled or damaged, which is not convenient for keeping the cable straight. For this reason, we propose an electrical connection device that is easy to replace the cable. Summary of the invention

[0007] Preferably, the rotating conductive component also includes an adjusting hole, a wiring hole, a conductive block and a pressing block. The wiring hole and the adjusting hole are arranged side by side on one end face of the rotating body. The conductive block is fixed on the inner side of the wiring hole and is electrically connected to the conductive plate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 The present invention provides a technical solution: an electrical connection device that is easy to replace cables, comprising: A plug 1, a conductive plug 5 is fixed on the lower surface of the plug 1, and a terminal 4 is arranged on the inner side of the plug 1 corresponding to the conductive plug 5; The mounting block 2 is fixed to one end of the inner side of the plug 1, and a rotating conductive component 8 is provided on the inner side of the mounting block 2 to electrically connect with the conductive plug 5 when rotating, so that after the rotating conductive component 8 is fixed to the cable in the later stage, both ends of the cable can rotate to avoid twisting, and a connecting wire 3 matching with the rotating conductive component 8 is provided on one side wall of the terminal 4, so that the rotating conductive component 8 and the conductive plug 5 can be electrically connected; A threaded barrel 6 is fixed to one end surface of the plug 1; The mounting ring block 9 is connected to the threaded barrel 6 through the threaded portion to facilitate the installation of the limit assembly 7; The conductive cable 11 is arranged inside the mounting ring block 9 and one end of the conductive cable 11 is electrically matched with the rotating conductive component 8. The other end of the conductive cable 11 is connected to the socket 10 through another rotating conductive component 8, so that the two ends of the conductive cable 11 can still rotate after wiring, thereby preventing the conductive cable 11 from twisting or twisting. The limiting component 7 is rotatably mounted on the inner side of the mounting ring block 9 to press the rotating conductive component 8 and the conductive cable 11 to fix them, so as to facilitate the fixing of the conductive cable 11.

[0020] Preferably, the rotating conductive component 8 includes a rotating body 801, a conductive column 802, a spring 803 and a conductive plate 804. The rotating body 801 is rotatably installed on the inner side of the mounting block 2, and a conductive plate 804 is provided on the outer surface of the rotating body 801. The conductive column 802 is slidably installed on one end of the inner side of the mounting block 2, and one end of the conductive column 802 is in contact with the conductive plate 804, so that when the rotating body 801 rotates itself, the current can still be transmitted to the conductive column 802. One end of the connecting line 3 is electrically connected to the conductive column 802, and a spring 803 is provided at one end of the conductive column 802, so that the spring 803 can be used to push the conductive column 802 to closely match the conductive plate 804 for conduction.

[0021] Preferably, the rotating conductive component 8 also includes an adjustment hole 805, a wiring hole 806, a conductive block 807 and a pressing block 808. The wiring hole 806 and the adjustment hole 805 are arranged side by side on one end face of the rotating body 801. The conductive block 807 is fixed to the inner side of the wiring hole 806 and is electrically connected to the conductive plate 804. The pressing block 808 is rotatably installed between the adjustment hole 805 and the wiring hole 806 to press the conductive cable 11 to contact the conductive block 807, so as to facilitate the later rapid compression and fixation of the conductive cable 11, or release the compression to replace the conductive cable 11.

[0022] Preferably, three wiring holes 806 are provided, and the lengths of the three wiring holes 806 extending toward the inside of the rotating body 801 are unequal, so as to respectively cooperate with the live wire, the ground wire and the neutral wire inside the conductive cable 11 .

[0023] Preferably, the cross section of the pressing block 808 is a trapezoid, so that the limiting pillar 702 can well resist the pressing block 808 to rotate and compress and fix the conductive cable 11 .

[0024] Preferably, three conductive plates 804 are provided, and the three conductive plates 804 are distributed at intervals along the circumference of the rotating body 801 .

[0025] Preferably, the limiting assembly 7 includes a ring plate 701 and a limiting column 702. The ring plate 701 is rotatably installed on the inner side of the mounting ring block 9, and the limiting column 702 is fixed to the inner side of the ring plate 701 by a support block, so that the limiting column 702 can move with the pressure block 808 after it contacts the pressure block 808.

[0026] Preferably, a plurality of limiting posts 702 are provided, and the limiting posts 702 are made of any one of ceramic, glass and plastic, which is convenient for insulation and avoids conduction of the limiting posts 702 .

[0027] Preferably, a dustproof rubber sleeve 901 is fixed to one end surface of the mounting ring block 9 to facilitate dustproof and waterproofing.

[0028] Preferably, the dustproof rubber sleeve 901 is conical to facilitate better protection, and the inner diameter of the smallest end of the dustproof rubber sleeve 901 is larger than the outer diameter of the conductive cable 11 .

[0029] The working principle and use process of the present invention are as follows: when the conductive cable 11 needs to be replaced, it is only necessary to manually twist the mounting ring block 9 so that the mounting ring block 9 drives the limiting assembly 7 to disengage from the inner side of the threaded barrel 6. At this time, the replaced conductive cable 11 is passed through the inner side of the mounting ring block 9 so that the three conductive wires inside the conductive cable 11 are respectively inserted into the inner sides of the three wiring holes 806. Then, the mounting ring block 9 is twisted to cooperate with the threaded barrel 6 through the threaded portion. At this time, the limiting assembly 7 is inserted into the inner side of the adjustment hole 805, and the limiting assembly 7 pushes one end of the pressing block 808 toward the conductive The block 807 moves so that the conductive wire contacts the conductive block 807 to be electrically connected. Similarly, the other end of the conductive cable 11 can be connected to the socket 10 to complete the installation. No special tools are required and the operation is simple. When the plug 1 and the socket 10 at both ends of the conductive cable 11 rotate in different directions, the conductive cable 11 is subjected to torsion, and the rotating body 801 rotates inside the installation block 2, which is convenient for keeping the conductive cable 11 straight, reducing the conductive cable 11 from being damaged due to large twisting or winding itself, and improving the safety of the device.

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