Because the sliding part 8 and the sliding fit part 9 are in concave-convex fit with each other, and the convex edges 25 on the two sides are respectively extended on the grooves 26 on the two sides, a triple concave-convex fit relation is formed between the sliding part 8 and the sliding fit part 9, so that the assembly stability between the sliding block 2 and the guide 5 is improved, the sliding block 2 cannot be easily separated from the guide 5 during sliding, and the sliding stability of the sliding block 2 is ensured.

The arc-shaped rotating positions are arranged on the sliding part 8, and/or the two side convex edges 25, and/or the sliding matching part 9, and/or the two side grooves 26; the rotation limiting positions 11 are arranged on the sliding part 8, and/or the two side flanges 25, and/or the sliding matching part 9, and/or the two side grooves 26.

The arc of this embodiment is rotated the position and is set up on sliding part 8, sliding fit portion 9 and both sides chimb 25 to it is more smooth and easy to make the normal running fit between sliding part 8 and the sliding fit portion 9, thereby avoids slider 2 to appear the card dead, and unable pivoted problem.

The rotation limiting position 11 is arranged on the grooves 26 at the two sides; the sliding part 8 rotates on the sliding fit part 9 in a limiting mode through the rotation limiting position 11, so that the problem that the sliding block 2 cannot reset due to too large rotation is avoided, the sliding block 2 is prevented from rotating at too large angle, larger gaps are formed in the side edges of the sliding block, the strip-shaped part is easily contacted with the electrode sleeve 4, and the use safety of the socket is ensured. At the same time, the front side of the sliding block 2 will lean against the front wall of the assembly cavity 13 when rotating, and the rotating position of the sliding block 2 can also be limited. Namely, the slide block 2 can realize the rotation limit of the front and back positions.

The electrode sleeve insert 4 is fixedly arranged on the base 1; the guide piece 5 is covered on the electrode sleeve 4 and positioned on the base 1. That is, the electrode cartridge 4 can be stably fitted between the guide 5 and the base 1.

The panel 12 is fixedly arranged on the base 1 and covers the sliding block 2 and the guide piece 5. I.e. the cooperation between the panel 12 and the base 1, enables a stable assembly of the protection plate 2 and the guide 5.

In order to improve the aesthetic property of the socket, the base 1 is also provided with a decorative plate 15, and the decorative plate 15 is fixedly arranged on the base 1 and covers the panel 12; the decorative plate 15 is provided with a decorative jack 16; the panel 12 is provided with a panel jack 17; the decorative jack 16, the panel jack 17, the gap 6 and the electrode sleeve 4 are arranged correspondingly; the slider 2 slides between the panel insertion hole 17 and the notch 6.

The present socket further comprises a resilient member 14; the sliding block 2 and/or the assembly cavity 13 and/or the guide piece 5 are/is provided with a sleeve joint part 20; the elastic piece 14 is elastically positioned and sleeved on the sleeving part 20; the slider 2 is always elastically slid on the fitting cavity 13 and the guide 5 in the direction of the notch 6 by the elastic member 14, and opens or closes the notch 6 when elastically slid.

The slider 2 and the fitting cavity 13 of the present embodiment are each provided with a socket 20. The elastic member 14 is a spring, and one end of the elastic member is elastically positioned and sleeved on the sleeving part 20 of the slider 2, and the other end of the elastic member is elastically positioned and sleeved on the sleeving part 20 of the assembling cavity 13, so that the elastic member 14 can well apply an elastic acting force on the slider 2. Meanwhile, the elastic piece 14 has a certain reset acting force, so that the sliding block 2 can be reset through the elastic piece 14 when sliding and rotating, the sliding block 2 can be ensured to slide and rotate on the assembly cavity 13 and the guide piece 5 in a reset mode, and the notch 6 is always closed.

Because the two driving inclined planes 3, the two sliding parts 19 and the two positioning surfaces 10 are respectively arranged left and right by taking the sliding part 8 as an axis, the left and right stable sliding of the sliding block 2 can be realized only by the elastic action of one elastic part 14 on the sliding block 2, the internal structure of the socket is simplified, meanwhile, the elastic part 14 is assembled by utilizing a positioning sleeve mode, the generated elastic acting force can be more intensively acted on the sliding block 2, and the elastic sliding of the sliding block is ensured to be more reliable.

The foregoing is a preferred embodiment of the present invention, and the basic principles, principal features and advantages of the invention are shown and described. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
