Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-2, the socket comprises a mounting box 1, a mounting frame 2 and an ejection mechanism 3. The mounting box 1 is a hollow structure with a horizontal interlayer 4, the structure is designed to be a cuboid structure, and a first through hole 5 is arranged on the interlayer 4. Mounting bracket 2 is fixed on mounting box 1, is equipped with second through-hole 6, third through-hole 7 and two at least jacks 8 on the mounting bracket 2, and jack 8 sets up around second through-hole 6, makes the plug can mutually support with pop-up mechanism 3 at the plug in-process like this, and second through-hole 6 sets up with 5 coaxial with first through-hole for subsequent pop-up mechanism 3's installation. In addition, the mounting bracket 2 is also provided with electrical components arranged in the existing socket, which does not belong to the technical key point herein and is not repeated.

The ejection mechanism 3 is mounted in the mounting box 1 and specifically includes a strike post 9, a spring 10, a projection 11 and a resilient support 12, as further described below with reference to fig. 3-5.

The impact post 9 is formed by coaxially connecting a first cylinder 13 and a second cylinder 14, the first cylinder 13 located at the upper portion has a larger cross-sectional area than the second cylinder 14 located at the lower portion so that the first cylinder 13 forms a boss 15 with respect to the second cylinder 14, the impact post 9 vertically penetrates the second through-hole 6 and the first through-hole 5 in this order, the first cylinder 13 is installed in the second through-hole 6 and protrudes from the second through-hole 6, and the second cylinder 14 is installed in the first through-hole 5. The second through hole 6 and the first through hole 5 are both circular hole-shaped, and the diameters thereof are designed to be the same as the first cylinder 13 and the second cylinder 14, respectively, so that the striker 9 can vertically move in the second through hole 6 and the first through hole 5, and is not easily displaced. In order to further prevent the striking pin 9 from generating rotational deviation, some limiting devices may be added, such as a limiting block designed in the second through hole 6 or the first through hole 5, and a sliding slot designed on the side wall of the first cylinder 13 or the second cylinder 14 to cooperate with the limiting block.

The spring 10 is sleeved on the second cylinder 14, the top end of the spring 10 abuts against the boss 15, the bottom end of the spring 10 abuts against the interlayer 4, and the spring 10 can be pressed by pressing the impact column 9.

The left side of the projection 11 is fixed on the side wall of the first cylinder 13, the top surface of the projection 11 is a plane 16 which has a horizontal included angle of 0-10 degrees and inclines towards the upper right, and the plane 16 can also be designed into a horizontal plane, and the slightly inclined design is designed to be matched with the elastic support 12 more conveniently. The right side of the convex block 11 is provided with a first inclined surface 17 which is connected with the plane 16 and inclines towards the lower right, the bottom surface of the convex block 11 is provided with a second inclined surface 18 which is connected with the first inclined surface 17 and inclines towards the upper right, and the joint of the first inclined surface 17 and the second inclined surface 18 forms a tip 25 which protrudes towards the right. The overall shape of the projection 11 is like a pyramid superimposed on the slope of a triangle, wherein the slope of the first slope 17 can be designed to be larger than the second slope 18, so that the elastic support 12 can be more easily detached from the projection 11 when released, preferably, the first slope 17 can be at an angle of 60 ° to the horizontal and the second slope 18 can be at an angle of 30 ° to the horizontal.

The elastic support 12 is formed by connecting a hook 19 and a feeler lever 20 which are both arc-shaped at an included angle, the included angle is an acute angle, the hook 19 is connected with the bottom of the feeler lever 20 to form a connecting part 21, the bottom end of the connecting part 21 is provided with a notch 22 the width of which is slightly smaller than the diameter of the second cylinder 14, and the hook 19 is smaller than the curvature radius of the feeler lever 20. A limiting column 23 is transversely arranged between the hook 19 and the feeler lever 20, and two ends of the limiting column 23 are respectively fixed on the front inner wall and the rear inner wall of the mounting box 1, so that the position of the elastic support 12 is kept adjacent to the impact column 9. The top of the hook 19 is provided with a hook 24, the upper part of the hook 24 is provided with a third inclined surface 26 matched with the second inclined surface 18, and the lower part of the hook 24 is provided with a fourth inclined surface 27 matched with the plane 16, so that the hook 24 can easily hook the bump 11 in a pressing state, and the hook 24 can easily separate in a releasing state. The contact rod 20 is positioned at the right side of the hook 19, and the top of the contact rod 20 is installed in the third through hole 7 and protrudes out of the third through hole 7 to form a vertical button structure.

In the natural state shown in fig. 3, when no plug is inserted into the socket, the bottom end of the connecting portion 21 abuts against the right side of the second cylindrical body 14 under the restriction of the position-limiting post 23, the hook 19 is held under the projection 11, and the hook 24 abuts against the second inclined surface 18.

In the pressed state shown in fig. 4, when the plug is inserted into the socket, the plug vertically presses the striking pin 9, the boss 15 moves downward, the spring 10 is compressed, the protrusion 11 presses the hook 19 downward, the hook 24 moves along the second inclined surface 18 to the plane 16, and the hook 19 hooks the protrusion 11, so that the spring 10 is kept in the compressed state.

As shown in fig. 5, in a release state, that is, when the plug needs to be pulled out, the feeler lever 20 is vertically pressed, the feeler lever 20 is pressed toward the striker 9, the notch 22 of the connecting portion 21 is pushed toward the second cylinder 14, because the width of the notch 22 is slightly smaller than the diameter of the second cylinder 14, the notch 22 is not clamped on the second cylinder 14, but due to the elastic force of the notch 22, the notch 22 is expanded to a certain extent, so that the feeler lever 20 generates a rebound force in a direction away from the second cylinder 14, and meanwhile, the tip 25 presses the hook 19 toward the right, so that the hook 19 is separated from the plane 16 and releases the limitation on the bump 11, the spring 10 and the striker 9 are restored to a natural state, the striker 9 is ejected from the second through hole 6, and the plug is struck, so that the plug can be easily pulled out. As shown in fig. 6, the notch 22 is preferably V-shaped and gradually increases in width toward the bottom end of the connecting portion 21, so that when the spring force is pushed toward the second cylinder 14, the spring force in the opposite direction is more easily generated. Here, elastic means such as elastic string can be designed at the gap 22 to make the elastic support 12 bounce effectively.
