Description

Technical Field

[0001] The utility model relates to an easy-to-pull out electric shock-proof socket strip. Background Art

[0002] Socket strips are a common electrical device in daily life. There are two common problems in the use of socket strips. One is that the socket strip usually needs both hands to unplug the plug, which is not convenient for disabled people to use, and is not convenient for use at a long distance or with one hand. The other is that children insert the metal wire out of curiosity and other reasons, which may cause electric shock. In order to ensure safety, in the prior art, the utility model with application number CN201020224902.0 discloses a switch socket strip, which includes a shell, a plurality of sockets, a plurality of positioning members and a plurality of conductive frames. The shell has a plurality of grooves connected to the inside of the shell formed on the upper surface, and the plurality of sockets can be slidably installed in the grooves of the shell, each socket has a plurality of conductive terminals, and each conductive terminal has a conductive block, a plurality of positioning members are inserted into the shell, and the upper end of each positioning member can be elastically upwardly accommodated in the groove of the shell, and a plurality of conductive frames are clamped in the shell, and the conductive blocks can contact or separate from the conductive frames. The socket strip is a conventional socket strip with a switch, which is used to ensure that the socket strip is disconnected when not in use to ensure safety. However, in daily life, users often ignore the switch and just unplug the plug, causing the socket strip to remain in the on state, which is dangerous. When the socket strip is in use, if children or other groups with no safety awareness touch the plug pin or the socket of the socket strip when unplugging the plug, dangerous accidents may easily occur.

[0038] Reference Figures 1 to 5 According to the embodiment of the utility model, the easy-to-pull and anti-electric shock socket includes a housing 100, a bottom housing 200, a safety mechanism 300, a pressing key 400 and a lifting block 500;

[0039] The surface of the housing 100 is provided with at least one insertion station 110, the insertion station 110 is provided with a neutral line jack 111 and a live line jack 112, the insertion station 110 is provided with a through hole 120 and a pressing hole 130, and the housing 100 has two wires built therein;

[0040] The bottom shell 200 is provided with a receiving cavity 210, and the receiving cavity 210 has at least one conducting station 220, and the conducting station 220 corresponds to the insertion station 110 one by one, and the conducting station 220 is provided with a neutral contact 221 and a live contact 222, and the neutral contact 221 and the live contact 222 correspond to the positions of the neutral jack 111 and the live jack 112 respectively;

[0041] The insurance mechanism 300 is arranged on the conductive station 220, and includes a frame 310, a movable lever 320, a reset member 330, a conductive contact 340 and a conductive contact sheet 350 with elasticity. The frame 310 is fixed in the housing 100, and the middle part of the movable lever 320 is rotatably connected to the frame 310. One end of the movable lever 320 is fixedly connected to the conductive contact 340, and the other end is located below the pressing hole 130. One end of the conductive contact sheet 350 is electrically connected to the neutral contact 221 or the live contact 222, and the other end is located above the conductive contact 340 and spaced from the conductive contact 340. The end of the movable lever 320 located below the pressing hole 130 is connected to the reset mechanism, and the reset mechanism is used to drive the end of the movable lever 320 located below the pressing hole 130 to swing upward;

[0042] The pressing key 400 is embedded in the pressing hole 130 in a liftable manner, and the lower end of the pressing key 400 abuts against the end surface of the movable lever 320;

[0043] The lifting block 500 is embedded in the through hole 120 in a liftable manner, and the lower end of the lifting block 500 overlaps the conductive contact piece 350. The lifting block 500 can be pressed down to drive the conductive contact piece to bend and abut against the conductive contact point 340.

[0044] Among them, when one wire is electrically connected to the live wire contact 222, the other wire is electrically connected to the conductive contact 340, and the neutral wire contact 221 is electrically connected to the neutral wire contact 221; when one wire is electrically connected to the neutral wire contact 221, the other wire is electrically connected to the conductive contact 340, and the live wire contact 222 is electrically connected to the neutral wire contact 221.

[0045] This embodiment has the following two working states in actual use:

[0046] Insert the plug into the socket strip: align two of the contacts of the plug with the neutral socket 111 and the live socket 112 respectively, insert the plug into the insertion station 110, and then insert the two contacts into the conductive station 220, so that the two contacts are in contact with the neutral socket 111 and the live socket 112 respectively, and are electrically connected;

[0047] At this time, in this working state, the plug will press down the lifting block 500, so that the lifting block 500 is pressed down in the through hole 120 (refer to Figure 4 ), so that the conductive contact piece 350 located under the lifting block 500 is deformed and contacts the conductive contact 340, so that the current is conducted. Specifically, the two wires can be connected to the live wire contact 222 and the neutral wire contact 221 respectively. After the entire socket strip is connected to the mains, the plug can be energized.

[0048] Plug out the socket strip: Press the push button 400 to make the push button 400 drop in the push hole 130 and drive one end of the movable lever 320 to swing down. Due to the lever principle, the other end of the movable lever 320 swings up and lifts up the conductive contact 340, thereby lifting up the end of the conductive contact sheet 350 that contacts the conductive contact 340, and lifting up the entire lifting block 500 (refer to Figure 5 ), the lifting block 500 extends out of the through hole 120, and can lift up the plug, making it convenient for the user to directly pull out the plug;

[0049] After the plug is unplugged, the push button 400 is released. Under the action of the reset mechanism, the movable lever 320 lifts the push button 400. At the same time, the end of the lever 320 also swings upward, while the end with the conductive contact 340 swings downward and returns to the bottom of the conductive contact sheet 350. At this time, the conductive contact sheet 350 without force is restored to its original position under the action of its own deformation force and is located above the conductive contact 340, and is spaced apart (refer to Figure 3 ).

[0050] In summary:

[0051] 1. The safety mechanism 300 ensures that the conductive contact 340 and the conductive contact sheet 350 are not in contact and conductive under normal conditions, so that one of the two wires cannot be directly conductive with the live wire contact 222 or the neutral wire contact 221. Even if it is directly connected to the mains, it cannot be powered on, thus avoiding the risk of electric shock under normal conditions;

[0052] 2. The movable lever 320 is used in conjunction with the pressing key 400 and the lifting block 500 to eject the plug without touching the plug, which is convenient to use.

[0053] Specifically, the conducting station 220 is provided with a mounting seat 223, and the neutral contact 221 and the live contact 222 are fixed on the mounting seat 223. The mounting seat 223 is provided with two grooves 2231, and the neutral contact 221 and the live contact 222 are embedded in the grooves 2231. This makes the structure in the accommodating cavity 210 more neat and convenient for future maintenance.

[0054] In some embodiments, reference Figure 2 The reset mechanism includes a mounting block 331 and a spring 332. The mounting block 331 can be lifted and lowered in the accommodating cavity 210. A rotating groove 3311 is provided on the surface of the mounting block 331. The end of the movable lever 320 is rotatably connected to the rotating groove 3311. The spring 332 is arranged between the mounting block 331 and the bottom surface of the bottom shell 200. The elastic force of the spring 332 is utilized to make the mounting block 331 have a tendency to always move upward, ensuring that the movable lever 320 can return to its original position, and the rotating groove 3311 is for avoiding motion interference. More specifically, the movable lever 320 can be provided with a long groove, and a rotating shaft is provided in the rotating groove 3311. The rotating shaft is inserted in the long groove and can rotate in the long groove and slide along the long groove. In addition, in order to ensure that the lifting path of the mounting block 331 is determined, the accommodating cavity 210 is provided with two guide columns 211, and the mounting block 331 is provided with two sliding holes 3312. The guide columns 211 are inserted in the sliding holes 3312 and are slidably connected to the sliding holes 3312.

[0055] Furthermore, in order to enable the conductive contact 340 to be conductive with the wire and facilitate the wire connection and installation, the end of the movable lever 320 is fixedly connected to a metal conductive sheet 341, the front end of the metal conductive sheet 341 is fixedly connected to the conductive contact 340, and the rear end of the metal conductive sheet 341 is electrically connected to the wire.

[0056] In daily use, the power strip is used to plug in multiple plugs, and accordingly, multiple conducting stations 220 and plugging stations 110 are provided.

[0057] Among them, in embodiment 1 of the present utility model, the conductive contact 350 is electrically connected to the neutral line contact 221, the live line contacts 222 of multiple conductive stations 220 are electrically connected, and multiple conductive contacts 340 are electrically connected to the same conductive wire (wherein the conductive wire has multiple branch lines, and the branch lines are electrically connected to multiple conductive contacts 340 respectively).

[0058] In the second embodiment of the present invention, the conductive contact 350 is electrically connected to the live wire contact 222, the neutral wire contacts 221 of the multiple conductive stations 220 are electrically connected, and the multiple conductive contacts 340 are electrically connected to the same conductive wire (wherein the conductive wire has multiple branch lines, and the branch lines are electrically connected to the multiple conductive contacts 340 respectively).
