Although the above safety socket solves the problem of preventing mis-insertion by two slides, the use of two slides leads to a relatively complex structure, more mutual interference, and easy to cause failures, and the manufacturing cost is relatively high. Due to the travel limit of its movable plate, it cannot cover more models of safety protection sockets, such as 20A safety protection sockets. Utility Model Content

The moving plate moves downward along the oblique slide groove with the sliders on both sides as fulcrums. During the translation process of the moving plate, the channel for insertion is given up to prompt the plug to continue to be inserted and achieve conductive plugging with the socket.

The two sliders are in the middle position of the movable plate. When the two plug rods of the socket are inserted, they are pressed against the movable plate at the same time. The pressed positions are located on both sides of the line connecting the two sliders. At this time, the two sides of the movable plate are evenly stressed and pressed down. During the pressing process, the slider is constrained by the oblique groove and slides downward obliquely, so that the through hole and the space on the rear side of the movable plate are aligned with the jack above. The plug is inserted into this channel to achieve conductivity. Since only one movable plate is used, the structure is relatively simple and the installation is more convenient. In addition, its movement is constrained by the cooperation of the slider and the oblique groove. Combined with the uninterrupted swing range protection limit of the upper inclined surface of the gear position and the side inclined surface of the gear position on the front side of the block, the entire moving process is more efficient and stable.

[0016] Second, in addition to being constrained by the slider and the oblique sliding groove, the movable plate is also protected by the upper inclined surface of the gear on the front side of the card block and the side inclined surfaces of the gear on both sides of the give way groove, thereby preventing the slide plate from over-flipping during the up and down translation process, which would cause inconvenience for translation, and thus making the translation after the socket is inserted smoother.

[0017] 3. A blocking piece is fixedly arranged in the bottom shell of the socket, and the plug piece in the socket forms a conductive plug end. The blocking piece extends into the mounting frame and is located above the conductive plug end at the front side socket. The blocking piece blocks a front part of the conductive plug end. When the socket plug rod is inserted, it enters the conductive plug end from the rear side of the blocking piece, thereby avoiding accidental electric shock when the needle-shaped conductive rod is inserted obliquely forward from the front side socket.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0032] The so-called "front" and "rear" in the present invention respectively refer to the right side as shown in the drawings as the front (specifically, the side where the blocking piece is provided as the front side) and the left side as the rear, wherein the right side is the direction in which the movable closing plate is translated after being pushed down by the double plugs.

[0033] Reference Figure 1-12As shown, the anti-misinsertion safety protection socket provided by Example 1 of the utility model includes a bottom shell 1 and a cover 2, the cover 2 has at least two sockets 3, the sockets 3 are for the plug rod to be inserted to realize conductive connection, the bottom shell 1 is provided with a mounting frame 5 for mounting a movable plate 4, the two side plates of the mounting frame 5 are provided with oblique sliding grooves 6 distributed obliquely, the movable plate 4 is arranged below the socket 3, the movable plate 4 is provided with at least one through hole 7 for the plug rod to pass through, the movable plate 4 is provided with an elastic reset mechanism, the elastic reset mechanism pushes the movable plate 4 to be in an initial position, the movable plate 4 shields the two sockets 3 in the initial position, the two sides of the movable plate 4 are provided with sliders 8, the sliders 8 are inserted into the oblique sliding grooves 6, and slide down in the initial position The block 8 is at the top of the oblique slide groove 6, and the movable plate 4 is provided with a blocking mechanism. When a single rod is inserted from the socket 3, the movable plate 4 is pushed, and the pushed movable plate 4 swings to prompt the blocking mechanism to realize buckling, thereby preventing the movable plate 4 from moving; when the two plug rods of the plug are inserted into the two sockets at the same time, the movable plate 4 is pushed synchronously, and the positions where the plug rods push against the movable plate 4 are located on both sides of the line connecting the two sliders 8. The movable plate 4 moves downward along the oblique slide groove 6 with the sliders 8 on both sides as fulcrums. During the translation process of the movable plate 4, a channel for insertion is given up to prompt the plug to continue to be inserted and realize conductive plugging with the socket. In this embodiment, after the movable plate 4 moves downward and forward, the through hole 7 and the rear end on the movable plate 4 respectively form channels for the insertion of the front and rear plug rods. In the above embodiment, the specific structure of the elastic reset mechanism is as follows: two sets of movable plates 4 and mounting frames 5 are arranged in the socket, and a set of jacks 3 on the surface cover 2 is correspondingly arranged above each set of movable plates 4 and mounting frames 5. The elastic reset mechanism includes a spring 9 arranged on the frame in the bottom shell 1, and the two ends of the spring 9 are tilted and respectively press against the front end plates of the movable plates 4 on both sides. The middle part of the spring 9 is in the shape of a straight strip, and the two ends are tilted toward the movable plate 4 to press against the movable plate 4.

[0034] Reference Figure 2-7As shown, in order to enable the moving plate 4 to be locked through the blocking mechanism after the single rod is inserted and the moving plate 4 is swung, and to prevent the moving plate 4 from sliding obliquely downward, the blocking mechanism of this embodiment includes a locking protrusion 41 arranged at the two corners of the upper side of the rear end of the moving plate 4 and a locking groove 42 at the lower side of the rear end, and also includes a protrusion locking groove 21 corresponding to the locking protrusion 41 on the lower side of the cover 2 and a locking block 51 matching the locking groove 42 and arranged on the mounting frame 5 corresponding to the locking groove 42, and the upper end of the locking block 51 has The locking end of the locking groove 42 can be locked. When the front jack 3 is inserted into the rod alone, the rear end of the moving plate 4 is tilted upward, prompting the locking protrusion 41 on the moving plate 4 to be locked into the protrusion locking groove 21 on the lower side of the cover 2. When the rear jack 3 is inserted into the rod alone, the rear end of the moving plate 4 swings downward, prompting the locking groove 42 on the moving plate 4 to be locked with the block 51. In both cases, the moving plate 4 can be blocked from moving downward, thereby maintaining the blocking state of the rod, and preventing the rod from being inserted into the conductive state due to the sliding of the moving plate to give way to the channel position. The above-mentioned blocking mechanism is set in various ways, and the innovation is more reflected in the structure that the locking is set both up and down, and the locking structure can be realized when swinging up and down. As for the specific locking mechanism, it can also be that a slot is set in the middle of the cover 2, and a block is set in the middle of the rear end of the moving plate 4, or a groove is set at the rear end of the mounting frame 5, and a protrusion is set on the moving plate 4.

[0035] Reference Figure 3-7 As shown, the front side of the block 51 is provided with a stopper upper inclined surface 511, which blocks the rear side end of the movable plate 4. The middle of the block 51 is provided with a notch 512 which passes straight through to the bottom, and the front side of the block 51 of the mounting frame 5 is provided with a clearance groove 513, the notch 512 in the middle of the block 51 is connected with the clearance groove 513, and a conductive plug end is provided below the clearance groove 513. The two sides of the clearance groove 513 are provided with stopper side inclined surfaces 514, which block the rear side end of the movable plate 4. In this embodiment, in addition to being constrained by the slider 8 and the oblique slide 6, the movable plate 4 is also protected by the stopper upper inclined surface 511 on the front side of the block 51 and the stopper side inclined surfaces 514 on both sides of the clearance groove 513, so as to prevent the movable plate 4 from overturning during the up and down translation process, which is not conducive to translation, thereby making the translation after the socket is inserted smoother.

[0036] Reference Figure 2-7 As shown, the slider 8 has a slider plane 81 on its upper side, and the upper end of the oblique slide groove 6 has a horizontally distributed upper plane 61. This structure enables the upper plane of the slider 8 to fit and position with the upper plane of the oblique slide groove 6 after the movable plate 4 is elastically reset and moved upward, and the movable plate 4 body is horizontally distributed laterally, and the slider 8 has an arc-shaped surface other than the plane part. The lower end of the oblique slide groove 6 has an arc-shaped bottom surface 62 of the slide groove that matches the arc-shaped surface of the slider, thereby enabling the movable plate 4 to quickly find the bottom after sliding down to the bottom.

[0037] Reference Figure 3 , Figure 4 , Figure 7 As shown, the middle of the locking groove 42 is provided with a middle stopper 43 , and when the upper end of the locking block 51 is locked into the locking groove 42 , the middle stopper 43 is embedded in the notch 512 .

[0038] Reference Figure 1 , Fig. 9 , Fig.10 As shown, in order to avoid electric shock caused by the insertion of a needle-shaped conductor, a blocking piece 10 is fixedly arranged in the bottom shell 1, and the plug piece in the socket forms a conductive plug end. The blocking piece 10 extends into the mounting frame 5 and is located above the conductive plug end at the front side plug hole. The blocking piece 10 blocks the front part of the conductive plug end. When the socket plug rod is inserted, it enters the conductive plug end from the back side of the blocking piece 10. The function of the blocking piece 10 is that when a single rod is inserted into the front side plug hole, because the movable plate has basically covered the top of the conductive plug end, it can block the rod that is usually close to or slightly smaller than the diameter of the plug rod, but there is a possibility of a very small gap between the front end of the movable plate and the mounting frame. If the single rod is an extremely small needle body, when the needle body is inserted obliquely forward into the front side plug hole 3, it is possible to pass through the gap and contact the conductive plug end, which will cause the risk of electric shock. However, when the blocking piece 10 is used to block the front part of the conductive plug end, this gap can be blocked, and the risk can be eliminated.

[0039] Reference Figure 2 , Figure 3 , Fig. 9 , Figure 10-12 As shown, the two side ends of the movable plate 4 in the utility model adopt sliders 8 to insert into the oblique slide grooves 6 of the two side plates of the movable frame 5 to achieve sliding cooperation. The two sliders 8 are in the middle position of the movable plate 4. When the two plug rods of the socket are inserted, they are pressed on the movable plate 4 at the same time, and the pressed positions are located on both sides of the line connecting the two sliders 8. At this time, the two sides of the movable plate are evenly stressed and pressed down. During the pressing process, the slider 8 is constrained by the oblique slide grooves 6 to slide obliquely downward, so that the through hole 7 and the space on the rear side of the movable plate 4 are aligned with the upper jack 3, and the plug is inserted into this channel to achieve conductivity. When a single rod is inserted from the front jack 3 alone, the rear end of the moving plate 4 tilts upward, causing the positioning protrusion 41 on the moving plate 4 to snap into the protrusion slot 21 on the lower side of the cover 2. When the rear jack 3 is inserted into the rod alone, the rear end of the moving plate 4 swings downward, causing the positioning slot 42 on the moving plate 4 to snap into the block 51. Both situations can prevent the moving plate 4 from moving downward, thereby maintaining the blocking state of the rod and preventing the conductive rod of the non-plug rod from slipping and giving way to the channel position and misleading the current. Since only one moving plate 4 is used, the structure is relatively simple and the installation is more convenient. In addition, its movement is constrained by the cooperation of the slider and the oblique slide groove, and the entire movement process is more efficient and stable.

[0040] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
