In one embodiment of the present utility model, referring to fig. 1-6, a charging plug 100 is disclosed that can be adapted to a charging socket 200. The charging plug is a high-current power supply connecting device, but is not limited to being applied to vehicle charging, unmanned aerial vehicle charging, dust collector charging, charging by adopting a high-current electric appliance and the like.

In the present embodiment, the charging plug (as shown in fig. 3 to 6) includes a plug terminal 10, an insulating tube body 20, and a conductive tube body 30, wherein:

the socket terminal 10 is made of metal pipe and has a fixing portion 11, and a socket portion 12 and a wire-bonding portion 13 extending from both ends of the fixing portion 11, wherein the socket portion 12 is split to form a plurality of inwardly contracted (and inclined) contact arms 121, which form contacts 1211 inwardly, the contacts are arc-shaped and are located near the free ends of the contact arms, and the arc-shaped contacts enable the free ends of the contact arms to tilt outwards so as to be convenient for fitting with a central terminal 51 provided in a charging socket. In the example, the fixing portion is formed with a snap ring 111, a punched through hole 112 and a baffle plate 113, and the baffle plate 113 plugs the lumen (not labeled) of the pipe and is located between the fixing portion and the welding line portion, so that molten tin is prevented from flowing forward to the fixing portion and/or the plugging portion through the lumen during welding line, and the use effect is affected; the wire bonding portion has a wire groove 131 for facilitating welding with a cable (not shown);

the insulating tube body 20 is molded and includes a main tube portion 21, a ring groove 22 formed near a front end of the main tube portion, and a collar 23 formed near a rear end of the main tube portion at a periphery of the main tube portion, wherein: the outer diameter of the front end part (not marked) formed by the connecting ring groove 22 is larger than the outer diameter of the ring groove but smaller than the outer diameter of the main body pipe part; the outer periphery of the main body pipe part near the front of the convex ring is retracted to form a groove 211 smaller than the outer periphery diameter, the convex ring is provided with a notch 231 and extends backwards to form a cambered surface line tail 212 which is consistent with the groove diameter, and the line tail is tile-shaped and is provided with a receiving groove (not labeled) with notches opposite to the notch. In the example, the connector terminal 10 is inserted into a lumen (not labeled) of the insulating tube 20, and interferes with an inner wall of the lumen through a snap ring 111 of the fixing portion, so that the connector terminal and the insulating tube are firmly integrated, the connector portion 12 is suspended in the lumen when not receiving external force (i.e. not receiving butt joint), at this time, the wire bonding portion 13 falls into the receiving groove, and the back surface of the wire groove 131 is attached to the receiving groove;

the conductive tube 30 is sleeved on the outer periphery of the insulating tube body and comprises a metal tube body 31 and a metal pin 32 connected with the rear end of the metal tube body and adapted to the groove 211. In the example, the metal tube body 31 includes a metal tube (not shown) that covers the main tube portion 21 and a recessed portion 311 that is at the front end of the metal tube and fills the annular groove 22 in an enclosed manner, the outside diameter of the recessed portion in the annular groove being equal to the outside diameter of the front end portion of the insulating tube body, so that the front end of the charging plug (through the recessed portion and the metal tube) forms a tapered slope that facilitates insertion (without damage) of the corresponding plug. In an example, the metal pin 32 includes a snap ring 321 and a foot portion 322 extending from one side of the snap ring, the snap ring has a split (not labeled), and can be expanded by an external force to be conveniently assembled in the groove 211, and the snap ring foot portion 322 assembled in the groove 211 is located at an extrados of the wire tail portion through the convex ring notch 231 to facilitate welding of the wire cable. In an example, the outer periphery of the elastic snap ring is stamped to form an outward protrusion 3211, when the metal tube body 31 is sleeved on the outer periphery of the insulating tube body, the tail end of the metal tube body surrounds the outer periphery of the elastic snap ring, so that the metal tube body and the elastic snap ring form electrical communication, and the protrusion of the elastic snap ring abuts against the inner wall of the tail end of the metal tube body, so that the contact effect of the metal tube body and the elastic snap ring is improved.
