[0002] Male and female connectors are also called male and female, which are the names people give to connectors of different shapes. This design is mainly to emphasize one-way flow. In mathematical graph theory, the power network consists of a plug (male) and a socket (female), and flows from the socket to the plug in a fixed direction. When the current of the connector product flows from one device to another, the male and female performance of the connector plays a good role, which can enhance the safety of the equipment and ensure the stable and normal operation of the equipment.

[0003] At present, in the field of new energy vehicle charging, basically all chargers use direct plug-in connection. This type of charger uses a male and female socket for hard connection, and uses force to force the connection between the pin needle and the pin hole. Although this connection method can solve certain problems to a certain extent, the plug-in life of this connection method is relatively short. The specific reason is that the direct plug-in connection cannot guarantee the verticality of the pin needle and the pin hole when plugging and unplugging, and will be inserted at different inclination angles, which is very damaging to the equipment. In the long run, it will lead to unstable electrical transmission, thereby causing the charger to be scrapped. Summary of the invention

[0004] The utility model mainly solves the technical problem that the existing electric motorcycle charger has a short plug-in life.

[0026] The avoidance member 221 includes a plug-in portion 221a plugged into the core assembly 12, a connecting portion 221b connected to the wire, and a retaining ring 221c. The limiting plate 222 is provided with a receiving hole 222a and a limiting baffle 222b for accommodating the connecting portion 221b. The retaining ring 221c is located between the limiting baffle 222b and the socket sleeve 21, and there is a gap between the upper ends of the retaining ring 221c and the limiting baffle 222b, and there is a gap between the outer periphery of the connecting portion 221b and the receiving hole 222a.

[0027] Specifically, the plug jacket 11 has two layers, the inner layer is made of TPEE material, and the outer layer is made of nylon containing 30% glass fiber. In other embodiments, the inner layer can also be made of nylon containing 30% glass fiber, and the outer layer can be made of PVC.

[0028] Specifically, a hook groove 3 is convexly provided on the outer surface of the plug housing 11, and a hook 31 is provided in the hook groove 3. The hook 31 is screwed to the hook groove 3 through a pin shaft 32 provided in the middle position thereof, and one end of the hook 31 is provided with a hook head 311 passing through the plug housing and facing inward, and the other end is provided with a snap button 312, and a spring is provided under the snap button 312, one end of the spring abuts against the snap button 312, and the other end abuts against the hook groove 3.

[0029] Specifically, the hole pitch of the accommodating holes 222a is 17-18 mm.

[0033] Working principle:

[0034] When inserting the male plug, align the pin needle with the female socket and insert it. At this time, the pin needle of the male plug must not be perpendicular to the pin hole of the female socket, that is, there is an error in the verticality. Since the plug-in part can be slightly deflected at this time, the plug-in part will be pressed to deflect the angle due to the error of the insertion angle to cater to the insertion angle of the pin needle. Since the retaining ring is located in the plug-in part, the retaining ring will deflect with the plug-in part to ensure a stable connection with the pin needle. At the same time, the hook groove will tighten the male plug and the female socket to ensure a stable connection. When charging is completed, press the hook and pull out the male plug.
