[0002] The battery of a three-wheeled / two-wheeled electric vehicle is the power source of the electric vehicle. It is a device that provides electricity to the motor of the electric vehicle and is an important factor in determining the mileage of the electric vehicle. Most of the existing lithium iron phosphate battery packs for three-wheeled / two-wheeled electric vehicles are charged at charging piles. Lithium batteries are small in size, light in weight, cost-effective, and can be used repeatedly.

[0003] When charging the lithium iron phosphate battery pack of a three-wheeled / two-wheeled electric vehicle, a special male plug needs to be connected to the socket hole of the vehicle body to provide a power signal. However, after the existing plug is plugged into the socket hole, there are the following shortcomings:

[0004] The plug generally includes two power female pins of different lengths. When the power female pins in the plug carry a large current, the two power female pins of different lengths are prone to short circuit, which can cause the male plug to catch fire, creating a major safety hazard.

[0025] See also Figures 1 to 7 In the embodiment of the utility model, a diamond-shaped power waterproof wire end male plug with the same positive and negative poles includes a non-detachable plug shell 2 and a non-detachable wire at its tail. The inside of the plug shell 2 is fixedly connected with an inner frame 3 for inserting the wire. The inner frame 3 is used to limit the wire at the tail end of the plug shell 2 to avoid the phenomenon that the plug and the wire are easily broken during use by consumers. The two side walls of the plug shell 2 are rotatably connected with a rocker pull ring 1 through the mutual cooperation of the rotating groove 12 and the rotating shaft 11. The two ends of the rocker pull ring 1 are respectively rotatably connected to the two side walls of the plug shell 2. A plug protection frame 4 is fixedly connected to the bottom side wall of the plug shell 2. An isolated first plug-in cavity 7 and a second plug-in cavity 10 are provided in the plug protection frame 4. Six signal female pins 9 are provided inside the first plug-in cavity 7, and two power female pins 8 are provided in the second plug-in cavity 10. Each signal female pin 9 and the power female pin 8 are connected to the electrical signal of the wire.

[0026] The two power female pins 8 have the same length to prevent two power female pins 8 of different lengths from being short-circuited and causing fire;

[0027] The two power female pins 8 are respectively positive and negative poles, the diameter of each power female pin 8 is 4mm, the diameter of each signal female pin 9 is 1mm, the surface of each signal female pin 9 and power female pin 8 is provided with a fire-resistant anti-oxidation coating, and the bottom end of each signal female pin 9 and power female pin 8 is chamfered. The material of the plug shell 2 is made of glass fiber reinforced PBT engineering plastic, the wire is composed of a soft cable, and the wire consists of an internal flame-retardant copper core and a polyvinyl chloride insulating sheath on the outside.

[0028] Specifically, grooves 6 are provided at the bottom of both the front and rear sides of the plug protection frame 4. The grooves 6 can make the bottom of the plug protection frame 4 easy to deform, thereby making it easier to insert into the corresponding socket hole.

[0029] Specifically, densely arranged anti-skid ridges 5 are provided on the outer side wall of the plug housing 2 , and the anti-skid ridges 5 enable the user to hold the plug housing 2 more firmly.

[0030] Specifically, a mounting groove is provided on the surface of the plug shell 2, and the ring handle of the rocker pull ring 1 is embedded in the mounting groove. A positioning structure is provided between the inner surface of the mounting groove and the circumferential outer surface of the rocker pull ring 1. When the rocker pull ring 1 is not in use, the rocker pull ring 1 can be rotated so that the ring handle at the top of the rocker pull ring 1 enters the mounting groove and is limited and fixed under the action of the positioning structure, thereby preventing the rocker pull ring 1 from shaking.

[0031] The working principle of the utility model is:

[0032] When in use, you can first grasp the plug shell 2 and insert the plug protection frame 2 into the corresponding socket hole, so that the signal female pin 9 can provide an electrical signal and the power female pin 8 can provide power. The power female pin 8 and the signal female pin 9 are respectively located in the isolated first plug-in cavity 7 and the second plug-in cavity 10, which not only avoids the interference between the power female pin 8 and the signal female pin 9, but also has high efficient waterproof performance. When it is necessary to unplug the plug, because the rocker pull ring 2 is located in the middle of the plug shell 2, it can be better vertically stressed when unplugged, and then the rocker pull ring 2 can be hooked and pulled outward to quickly and easily remove the plug.

[0033] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
