DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] like Figure 1-6As shown, an electrical connector with a locking function is proposed in one embodiment of the utility model. The electrical connector with a locking function designed in this scheme can realize the convenient connection and use of the electrical connector, and can meet the use effect of multiple plugging and unplugging without damage, including a first end 1 and a second end 2, the first end 1 and the second end 2 are matched and connected, the first end 1 is matched and connected with an unlocking piece 3, the first end 1 is matched and provided with a pleated sealing gasket 4, a plurality of limiting pieces 5 are slidably connected in an annular array on the second end 2, the limiting piece 5 is matched and provided with the unlocking piece 3, the second end 2 and the pleated sealing gasket 4 are matched and conflicted, the second end 2 is matched and provided with a top contact piece 6, the top contact piece 6 is matched and conflicted with the first end 1, when using the first end 1 and the second end When the head 2 is plugged in, the plug pin 102 is plugged into the plug column 202. At this time, the several limiting members 5 arranged on the second plug connector 201 will abut against the plug pin 102. By designing that the inclined surface of the limiting bevel 501 faces the side of the plug pin 102, when the tapered tube 103 abuts against the inclined surface of the limiting bevel 501, the limiting bevel 501 will be forced to shrink into the second plug connector 201, thereby squeezing the second spring 502 to keep the rebound force. When the limiting bevel 501 is at the alternating position between the tapered tube 103 and the sliding groove 104, the second spring 502 rebounds to reset the limiting bevel 501. At this time, the limiting bevel 501 can abut against one end of the tapered tube 103, so that the first end 1 and the second end The plug-in of the first end 1 and the second end 2 can be used to prevent retreat. At this time, it is difficult to pull the first end 1 and the second end 2 apart by brute force, thereby improving the connection effect. When the first end 1 and the second end 2 are plugged in, the second plug connector 201 will abut against one end of the pleated sealing gasket 4, and the pleated sealing gasket 4 can act between the connection gap between the first end 1 and the second end 2 to achieve a sealing and waterproof effect at the connection gap. When the first end 1 and the second end 2 need to be disconnected, the first end 1 and the second end 2 are pushed in opposite directions. At this time, since the plug-in pin 102 is plugged in the plug-in column 202 with a reserved pushing distance, and the top contact ring 601 abuts against one end of the plug-in pin 102, and the third spring 602 acts on one side of the top contact ring 601, it can be connected to the plug-in pin. When the first end 1 and the second end 2 are plugged in, the plugging of the plug pin 102 and the plug post 202 will not be easily pushed. When the first end 1 and the second end 2 are pushed toward each other, the top contact ring 601 will be resisted and slide in the second plug connector 201, so that the third spring 602 is squeezed and contracted. At this time, the limiting bevel 501 will resist the outer wall of the conical ring 301. At this time, by quickly pulling the first end 1 and the second end 2 toward both ends, the limiting bevel 501 will resist the conical ring 301 to make the conical ring 301 slide in the sliding groove 104. The wider side of the conical ring 301 resists the wider side of the conical tube 103. When the conical ring 301 and the conical tube 103 are fitted, the first spring 302 will be stretched to maintain the rebound force.The rebound force of the first spring 302 is smaller than the rebound force of the second springs 502. When the first end 1 and the second end 2 are pulled to disconnect, the limiting bevel 501 will slide on the combined area of ​​the conical tube 103 and the conical ring 301, and the limiting bevel 501 will slide from the conical ring 301 to the conical tube 103, so as to achieve the unlocking effect of the limiting bevel 501. At this time, the first end 1 and the second end 2 can be disconnected. After the two are disconnected, the first spring 302 rebounds to reset the conical ring 301, the third spring 602 rebounds to reset the top contact ring 601, and the second spring 502 rebounds to reset the limiting bevel 501, so that the first end 1 and the second end 2 can be conveniently connected for the next time, and the use effect of multiple plugging and unplugging without damage can be achieved, which meets the convenience of connection and use.
