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] like Figures 1 to 3 As shown, an embodiment of the present application provides an anti-dropping plug and socket, comprising a plug assembly 2 and a socket assembly 1 that cooperate with each other. The socket assembly 1 comprises a socket front cover plate 11, a socket rear cover plate 13, and a spring contact assembly 12 fixedly connected between the socket front cover plate 11 and the socket rear cover plate 13, the spring contact assembly 12 comprises a conductive plate 121 and two contacts 122 relatively slidably connected to the conductive plate 121, a conductive slot is formed between the two contacts 122, and a spring 123 is arranged between each contact 122 and the conductive plate 121. The plug assembly 2 comprises a conductive plug 23 that can be inserted into the conductive slot. A latch structure 3 is also arranged between the plug assembly 2 and the socket assembly 1 to prevent the plug assembly 2 and the socket assembly 1 from rotating loose.
[0025] During operation, the conductive plug 23 of the plug assembly 2 is electrically connected to the target electrical device, and the spring contact assembly 12 of the socket assembly 1 is electrically connected to the power supply through wires. When the conductive plug 23 is inserted into the conductive slot, the power supply and the target electrical device are electrically connected. The two contacts 122 can clamp the conductive plug 23 under the elastic force of the spring 123, and the pin structure 3 can be connected between the plug assembly 2 and the socket assembly 1 to prevent the two from rotating loose.
[0026] In the above manner, by setting the conductive plate 121, the spring 123 and the two contacts 122, the elastic force of the spring 123 is used to clamp the two contacts 122 on the conductive plug 23, so that the plugging and unplugging of the conductive plug 23 is more labor-saving, avoiding the situation where forced plugging and unplugging causes damage to the utility model and leakage, and has better contact tightness and is not prone to loosening. At the same time, it can reduce the mechanical fatigue of the contact 122, which is beneficial to extending the service life; by setting the pin structure 3, the rotation of the plug assembly 2 relative to the socket assembly 1 can be avoided, further improving the anti-loosening ability of the utility model.
[0027] In this embodiment, Figure 3 As shown, the conductive plate 121 is an integrally formed U-shaped member with an opening 331 facing upwards, which is formed by a bottom wall 1212 and two side walls 1211.

The sliding portion 1222 can slide relative to the connecting groove. The conductive plate 121 and the contact 122 are both made of copper. During operation, when the conductive plug 23 is inserted into the extruded contact portion 1221, the sliding portion 1222 slides outwards to compress the spring 123.

Through the setting of the conductive wire 125, good electrical contact between the conductive plate 121 and the limiting portion 1223 can be ensured.
[0030] In this embodiment, the conductive slot is formed between the two contact portions 1221 and is arc-shaped. The arc-shaped conductive slot is advantageously used to expand the conductive area, so that the conductive plug 23 can contact the conductive slot at multiple positions.
[0031] In this embodiment, the front cover plate 11 of the socket is provided with an accommodating cavity for accommodating the spring contact assembly 12, and the spring contact assembly 12 is detachably installed in the accommodating groove.

The plug cover 22 is detachably connected to one end of the plug socket 21 close to the second conductive locking screw 24, and the specific connection method is: an insertion portion adapted to the inner peripheral wall of the plug cover 22 is provided on the plug socket 21, and the inner peripheral wall of the plug cover 22 is tightly matched with the outer peripheral wall of the insertion portion. By providing the plug cover 22, the wiring harness can be prevented from being exposed, which is conducive to reducing the risk of electric shock.
[0033] In this embodiment, a cylindrical cavity 211 is provided at one end of the plug socket 21 away from the plug cover 22, and the conductive plug 23 partially extends into the cylindrical cavity 211. The socket front cover 11 includes a cylindrical protrusion 111 adapted to the cylindrical cavity 211, and the cylindrical protrusion 111 can extend into the cylindrical cavity 211.

The socket front cover 11 also includes a bottom plate 112 arranged near one end of the socket rear cover 13, and the bottom plate 112 is fixedly connected to the cylindrical protrusion 111. A sliding groove 212 is arranged on the outer wall 1211 of the plug socket 21 toward the bottom plate 112, and the shifting block 32 is slidably connected to the sliding groove 212. The outer wall 1211 of the plug socket 21 is near the bottom plate 11 2 is also provided with an annular groove 213, the retaining ring 33 is engaged in the annular groove 213 to limit one end of the shift block 32, the retaining ring 33 is provided with an opening 331 for the latch block 321 to extend toward the bottom plate 112, the elastic member 34 is provided between the shift block 32 and the plug socket 21 away from one end of the retaining ring 33, the elastic member 34 is used to push the shift block 32 and the latch block 321 to slide toward the bottom plate 112, and the bottom plate 112 is provided with a latch hole 31 at a relative position of the latch block 321. The slide groove 212 is a dovetail groove, and the shift block 32 is provided with a dovetail slider that slides with the dovetail groove.
[0035] In the above method, when the plug assembly 2 and the socket assembly 1 are connected in place, the elastic member 34 pushes the latch block 321 to be inserted into the latch hole 31 to prevent the plug assembly 2 from rotating circumferentially. Through the setting of the dovetail groove and the dovetail slider, the shift block 32 will not loosen radially.
[0036] In this embodiment, the conductive plug 23 is arranged to be arc-shaped, and the arc length of the conductive plug 23 is half of the arc length of the socket 1111.

[0037] Through the above arrangement, when the plug assembly 2 and the socket assembly 1 are axially plugged into place, the plug assembly 2 is rotated so that the latch block 321 is aligned and inserted into the latch hole 31. At this time, the anti-loosening portion just abuts against the inner top wall of the socket front cover 11, thereby achieving axial limiting, so that the plug assembly 2 and the socket assembly 1 are not easy to loosen axially.
[0038] In this embodiment, the jacks 1111 are provided in a plurality, and each jack 1111 is provided with a corresponding spring contact assembly 12.
