Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

One of the core ideas of the utility model lies in that a plug is provided, include: plug insulating casing 2, at least one metal plug-in components 1 and at least one elasticity extrusion module, elasticity extrusion module includes button and scarf elastic element, scarf elastic element includes scarf piece 5, scarf piece 5 is equipped with first scarf and second plane, metal plug-in components 1 are located in plug insulating casing 2, and 1 one end of metal plug-in components and second plane fixed connection, plug insulating casing 2 is equipped with the through-hole of wearing to establish metal plug-in components 1, button one end and first scarf butt, the other end passes plug insulating casing 2, metal plug-in components 1 is perpendicular with the button. The metal plug-in 1 is stretched out and drawn back through the wedge-shaped surface, the plug is easily plugged and pulled out, the structure is simple, and the cost is low.

Referring to fig. 1, a block diagram of a plug according to the present invention is shown, which may specifically include: plug insulating casing 2, at least one metal plug-in components 1 and at least one elasticity extrusion module, elasticity extrusion module includes button and scarf elastic element, scarf elastic element includes scarf piece 5, scarf piece 5 is equipped with first scarf and second plane, metal plug-in components 1 are located in plug insulating casing 2, and 1 one end of metal plug-in components and second plane fixed connection, plug insulating casing 2 is equipped with the through-hole of wearing to establish metal plug-in components 1, button one end and first scarf butt, the other end passes plug insulating casing 2, metal plug-in components 1 is perpendicular with the button. In this embodiment, the metal plug-in 1 is used for connecting with a power-generating lead, the cross section of the metal plug-in 1 is rectangular, the working principle of the plug disclosed in this embodiment is that when the plug is inserted into a socket, a single hand applies pressure to a key, the key applies the pressure to a first wedge surface in a wedge surface elastic unit, the first wedge surface in this embodiment is set to be an inclined surface with a preset angle, the preset angle in one embodiment is 45 degrees, in other embodiments, inclined surfaces with other angles are adopted according to different requirements, after the wedge surface elastic unit is pressed by the key, the metal plug-in 1 is driven to contract back into the plug head insulating shell 2 while being compressed, the single-hand operation of plug pulling-out is realized, the expansion and contraction of the metal plug-in 1 are realized through the wedge surface, the plug is easy to plug-in and pull-out, the structure is simple, the cost is low, and the plug, the operator is not easy to contact with the socket and the metal plug-in 1, and the safety of the user is ensured.

In this embodiment, the key includes a first portion 3 and a second portion 4, the second portion 4 is a circular arc surface, one end of the first portion 3 is fixedly connected with the second portion 4, and the other end of the first portion passes through the plug insulating housing 2. Through setting up above-mentioned case into first portion 3 and second portion 4 in this embodiment, second portion 4 sets up to the arc surface, and frictional force when can reducing second portion 4 and first scarf contact reduces the loss of its device, prolongs the life of product, and the light laborsaving, the practicality is stronger simultaneously of operation.

In this embodiment, a silicone pad is sleeved on an end of the first portion 3 away from the second portion 4.
