Description

Technical Field

[0001] The utility model relates to the field of electrical appliance accessories, in particular to a quick-connect plug. Background Art

[0002] In existing plugs, the rear ends of the pins located in the plug body are often directly connected by screws to form a wiring mechanism. When connecting, it is necessary to use a screwdriver to loosen the screws, insert or wrap the wires, and then tighten the screws to complete the wiring, which has the problem of complicated wiring. At the same time, according to the way the wires are fixed, they are divided into compression type and top-tightening type. The compression type uses the nut of the screw to press the wires onto the pins, which is suitable for soft wires but not friendly to hard wires (not easy to bend). The top-tightening type uses the end of the screw to abut against the wire, which is suitable for hard wires but not friendly to soft wires (it is easy to break the soft wire conductor).

[0013] The utility model is further configured as follows: the shell is provided with a handle slot, and the handle is hinged to the handle slot through a hinge shaft; the two ends of the handle are respectively a free end and a power storage end, and when the free end flips upward from the handle slot, the lower hem of the power storage end abuts against one end of the upper support section close to the lifting part and pushes the lifting part to move downward, causing the bottom of the clamping mouth to separate from the bottom surface of the abutting part.

[0014] In the above structure, the handle is flipped up, and the power storage end swings down to push the upper support section close to one end of the lifting part, so that the bottom of the clamping mouth moves downward and separates from the bottom surface of the abutment part of the hardware contact to form a clamping area. After the wire is inserted, the handle is flipped down, and the upper support section is reset by the elastic force of the elastic side to make the bottom of the clamping mouth move upward and clamp the wire between the bottom of the clamping mouth and the bottom surface of the abutment part.
