The embodiment provides a socket which can be applied to a PLC-IOT product, and particularly can be matched with a plug to realize safe connection between two devices.

In other embodiments, the socket may also be used for connection between appliances such as household appliances. Of course, the socket may be a fixed socket or a mobile socket (i.e., a strip socket).

As shown in fig. 1 and 2, the receptacle includes a safety shield mechanism 100, a circuit board 200, and a housing assembly 300. The housing assembly 300 may include an upper cover 310 and a bottom cover 320 that are coupled to each other in a snap-fit manner, and an accommodating space is formed between the upper cover 310 and the bottom cover 320, and the safety mechanism 100 and the circuit board 200 may be mounted in the accommodating space of the housing assembly 300.

When the plug is connected to the socket, the pins on the plug can be inserted into the receiving space from one side of the upper cover 310 and connected to the circuit board 200 in an inserting manner, and correspondingly, the upper cover 310 can be provided with inserting holes 311 for the pins to pass through. In one embodiment, safety shield mechanism 100 is disposed on a side of circuit board 200 adjacent to cover 310. When the pin is inserted into the circuit board 200, the pin needs to pass through the safety protection mechanism 100 to ensure the safe connection between the pin and the socket.

Referring to fig. 12 and 13, in the embodiment, the circuit board 200 is provided with spring strips 210 for engaging with the pins, and the spring strips 210 are used for holding the electrical connection pins. It is understood that the spring plate 210 may be fixed to the circuit board 200 by soldering, and the spring plate 210 is electrically connected to the circuit board 200. Meanwhile, the spring plate 210 may be disposed corresponding to the insertion hole 311.

As shown in fig. 1, 3, 4, and 7, safety shield mechanism 100 includes a mount 110 and a shield plate 120. Wherein, at least two through holes 1111 are disposed on the mounting base 110. Correspondingly, the upper cover 310 may be provided with at least two insertion holes 311, at least two via holes 1111 may be disposed in one-to-one correspondence with the insertion holes 311 on the bottom case 320, and the via holes 1111 are coaxial with the corresponding insertion holes 311. Correspondingly, the circuit board 200 is provided with at least two spring pieces 210, which are arranged corresponding to the insertion holes 311 one by one.

The protection plate 120 is rotatably mounted on the mounting seat 110, and a gap is formed between the protection plate 120 and the mounting seat 110. Thus, when the guard plate 120 rotates with respect to the mount 110, the rotational resistance of the guard plate 120 may be reduced.

In some embodiments, the shield plate 120 may include a shielded state 120a and an open state 120b with respect to the mount 110. When the protection plate 120 is in the protection state 120a, the protection plate 120 may cover at least two through holes 1111 on the mounting seat 110. When the protection plate 120 is in the open state 120b, the protection plate 120 may be misaligned with the at least two through holes 1111 of the mount 110.

The protection plate 120 may be disposed on a side of the mounting base 110 adjacent to the upper cover 310. That is, when the protection plate 120 is in the protection state 120a, the protection plate 120 may be blocked between the via 1111 and the corresponding insertion hole 311, thereby preventing the pin from passing through. When the protection plate 120 is in the open state 120b, the through holes 1111 may be in one-to-one correspondence communication with the insertion holes 311, so that the insertion pins may be inserted into and connected to the circuit board 200 after passing through the through holes 1111.

In use, when the receptacle is not plugged with a plug, the protection plate 120 may be in the protection state 120a, i.e., the protection plate 120 is blocked between the through hole 1111 and the corresponding mating hole 311. When the socket is connected with the plug, after the contact pin on the plug enters the accommodating space of the shell assembly 300 through the inserting hole 311, the contact pin can extrude the protection plate 120 to order to drive the protection plate 120 to rotate until the protection plate 120 and the via hole 1111 are staggered, so that the via hole 1111 is communicated with the corresponding inserting hole 311, and the contact pin smoothly passes through the via hole 1111 and then is inserted into the circuit board 200.

In the conventional safety socket, the protection plate 120 is usually slidably connected to the mounting seat 110, and the protection plate 120 is closely attached to the mounting seat 110. When the protection plate 120 is switched from the protection state 120a to the open state 120b, on one hand, the elastic force of the spring needs to be overcome, and on the other hand, the frictional resistance applied to the protection plate 120 by the mounting seat 110 needs to be overcome, so that a large resistance exists when the plug is connected with the socket, which is not beneficial to the connection of the plug and the socket.

In the present application, the protection plate 120 is rotatably mounted on the mounting base 110, and a gap is formed between the protection plate 120 and the mounting base 110. When the protection plate 120 is switched from the protection state 120a to the open state 120b, the mount base 110 does not apply frictional resistance to the protection plate 120, so that the rotational resistance of the protection plate 120 can be significantly reduced, and the insertion resistance when the plug is connected to the socket can be reduced, thereby facilitating the connection of the plug and the socket.

In an embodiment, safety shield mechanism 100 further includes a resilient member 130. The elastic member 130 may be connected between the protection plate 120 and the mounting base 110, and the elastic member 130 is used to drive the protection plate 120 to be in the protection state 120a, that is, the protection plate 120 may be in the protection state 120a under the action of the elastic member 130, so that the protection plate 120 is blocked between the through hole 1111 and the corresponding insertion hole 311. When the plug is connected with the socket, only the elastic resistance of the elastic member 130 is overcome.

As shown in fig. 3-9, the mounting base 110 may include a base plate 111 and an enclosure plate 112. The surrounding plate 112 may be disposed around an edge of the bottom plate 111, and the surrounding plate 112 may be perpendicular to the bottom plate 111. Accordingly, the bottom plate 111 and the surrounding plate 112 may enclose a mounting cavity with one side opened, and the shielding plate 120 may be rotatably mounted in the mounting cavity.

The via 1111 may be opened on the bottom plate 111. In an embodiment, a mounting shaft 113 is convexly disposed on a side of the base plate 111 close to the protection plate 120, the protection plate 120 is rotatably mounted on a side of the mounting shaft 113 away from the base plate 111, and a gap is formed between a side of the protection plate 120 close to the base plate 111 and the base plate 111. Thus, frictional resistance applied to the shielding plate 120 by the base plate 111 can be prevented when the shielding plate 120 rotates.

Referring to fig. 10 and 11, in some embodiments, the protection plate 120 may include a connecting portion 122 and at least two shielding portions 121, wherein the connecting portion 122 is rotatably connected to the mounting shaft 113 for connecting the protection plate 120 to the mounting base 110. At least two shielding portions 121 are disposed around the connection portion 122. In an embodiment, the connecting portion 122 and the at least two shielding portions 121 may be integrally formed.

In an embodiment, the at least two shielding portions 121 may be disposed in one-to-one correspondence with the at least two via holes 1111, that is, when the protection plate 120 is in the protection state 120a, the at least two shielding portions 121 may respectively shield the corresponding via holes 1111.

In some embodiments, the upper cover 310 is provided with two insertion holes 311, correspondingly, the mounting seat 110 is provided with two through holes 1111, the protection plate 120 includes two shielding portions 121, and the circuit board 200 may be provided with two corresponding spring tabs 210.

In other embodiments, three, five, etc. insertion holes 311 may be provided in the upper cover 310. Correspondingly, the through holes 1111, the shielding parts 121 and the spring pieces 210 can be arranged in the same number as the insertion holes 311. A plurality of shielding portions 121 may be disposed at intervals around the connection portion 122.

In the embodiment, the two shielding portions 121 are disposed on two sides of the connecting portion 122, and the two shielding portions 121 are similar in structure, and the two shielding portions 121 are rotationally symmetric about the rotation axis of the protection plate 120. Accordingly, the two vias 1111 may also be rotationally symmetric about the mounting shaft 113.

In other embodiments, the two shielding portions 121 may be spaced around the rotation axis of the shielding plate 120, and the included angle between the two shielding portions 121 may be set to be less than 180 °. Of course, in other embodiments, the two shielding portions 121 may also be disposed on the same side of the connecting portion 122, that is, the two shielding portions 121 may be disposed on the same rotation radius of the protection plate 120.

In the embodiment, one of the shielding portions 121 is described in detail. As shown in fig. 3, 5 and 7, a slope 123 is disposed on a side of the shielding portion 121 away from the bottom plate 111, and when the pin presses the protection plate 120, the pin can abut against the slope 123, so as to push the protection plate 120 to rotate. In some embodiments, the guard plate 120 may rotate counterclockwise when the guard plate 120 is switched from the shielding state 120a to the open state 120 b.

In other embodiments, when the shielding plate 120 is switched from the shielding state 120a to the opening state 120b, the shielding plate 120 may also rotate clockwise.

The ramp 123 may include two ends, a first end 1231 and a second end 1232. The vertical distance between the first end 1231 and the bottom plate 111 can be denoted as a distance n, the vertical distance between the second end 1232 and the bottom plate 111 can be denoted as a distance m, and the distance n can be smaller than the distance m. Meanwhile, when the shielding plate 120 is switched from the shielding state 120a to the opening state 120b, the second end 1232 is located in front of the movement of the first end 1231, i.e., the first end 1231 moves following the second end 1232.

Referring to fig. 4 and 6, the two shielding portions 121 form an equi-armed lever structure through the mounting shaft 113, that is, when one shielding portion 121 moves toward the bottom plate 111, the other shielding portion 121 can move away from the bottom plate 111, and the mounting shaft 113 can serve as a support structure of the equi-armed lever.

Accordingly, the two shielding portions 121 may include a balanced state 121a and an unbalanced state 121 b. It can be understood that when the two shielding parts 121 are in the equilibrium state 121a, the two shielding parts 121 are at the same distance from the bottom plate 111. When the two shielding parts 121 are in the unbalanced state 121b, the distance between one of the shielding parts 121 and the bottom plate 111 is greater than the distance between the other shielding part 121 and the bottom plate 111.

Referring to fig. 11, a stop block 124 protrudes from each of the two shielding portions 121 near the bottom plate 111, and the stop block 124 and the shielding portion 121 can be integrally formed. When the two shielding portions 121 are in the balanced state 121a, a gap is formed between the end surface of the stopper 124 facing away from one end of the shielding portion 121 and the bottom plate 111, so that the protection plate 120 rotates smoothly. When the two shielding portions 121 are in the unbalanced state 121b, one of the stoppers 124 is inserted into the corresponding through hole 1111 to prevent the protection plate 120 from rotating, i.e., prevent the protection plate 120 from being switched from the protection state 120a to the open state 120 b. It can be understood that, among them, the stopper 124 on the shielding portion 121 moving toward the bottom plate 111 is inserted into the corresponding via 1111.

When only one pin is inserted in the process of connecting the plug to the socket, the shielding portion 121 on the corresponding side moves in a direction approaching the bottom plate 111, and the shielding portion 121 on the other side tilts in a direction away from the bottom plate 111. Therefore, the two shielding portions 121 can be in an unbalanced state 121b, so that the stopper 124 at the corresponding position is inserted into the corresponding through hole 1111, and the shielding portions 121 can be prevented from rotating, that is, the protection plate 120 can be prevented from rotating under the restriction of the through hole 1111. Furthermore, a single pin can be prevented from passing through the safety protection mechanism 100 and then being connected with the circuit board 200. Namely, the socket provided by the application can avoid a contact pin of the plug to be inserted into the socket to be conducted, so that the safe plugging of the plug and the socket is realized, and the protection of equipment is further realized.

It can be understood that when two pins are inserted into the socket at the same time, and can abut against the corresponding shielding portions 121 at the same time, the two shielding portions 121 can be in a balanced state 121a, so as to prevent the stopper 124 from being inserted into the through hole 1111, and further prevent the rotation of the protection plate 120 from being hindered. Meanwhile, the two pins can simultaneously press the two shielding portions 121 to drive the protection plate 120 to rotate, so that the protection plate 120 rotates from the protection state 120a to the open state 120 b.

In some embodiments, the stopper 124 may be cylindrical. Of course, the stopper 124 may be configured as a triangular prism, a quadrangular prism, a pentagonal prism, etc. The side of the stop block 124 away from the shielding portion 121 can also be an inclined surface, which can reduce material cost. Accordingly, a distance between one side of the stopper 124 and the shielding portion 121 may be greater than a distance between the other side of the stopper 124 and the shielding portion 121. When the protection plate 120 is switched from the protection state 120a to the open state 120b, the side of the blocking portion 124, which is farther from the shielding portion 121, is located in front of the blocking portion 124, so that the blocking portion 124 can be smoothly inserted and limited in the corresponding through hole 1111 when the two shielding portions 121 are in the unbalanced state 121 b.

As shown in fig. 3, 4, and 7 to 11, the connecting portion 122 may be annular and is sleeved outside the mounting shaft 113. Meanwhile, at least one stroke slot 1131 is formed at one end of the mounting shaft 113 away from the bottom plate 111. Correspondingly, at least one sliding block 1221 is convexly arranged on the inner wall of the connecting part 122, and the sliding block 1221 protrudes towards the direction close to the axis of the connecting part 122. In an embodiment, the sliders 1221 are disposed in one-to-one correspondence with the stroke grooves 1131, and the sliders 1221 are slidably inserted into the corresponding stroke grooves 1131. It will be appreciated that the blocks 1221 may slide within the corresponding travel slots 1131 as the guard plate 120 rotates relative to the mount 110. In some embodiments, two symmetrical stroke slots 1131 may be formed on the mounting shaft 113, and two symmetrical sliders 1221 may be correspondingly formed on the connecting portion 122.

In other embodiments, the mounting shaft 113 may further define one, three, four, etc. stroke slots 1131, and of course, the connecting portion 122 may define an equal number of sliders 1221.

In an embodiment, the stroke slot 1131 cooperates with the sliding block 1221 to limit the rotation stroke of the protection plate 120, so as to prevent the protection plate 120 from rotating excessively. Specifically, when the protection plate 120 rotates to the protection state 120a, the slider 1221 may abut against the end wall at one end of the stroke groove 1131, so as to prevent the through hole 1111 from being communicated with the corresponding insertion hole 311 due to excessive rotation of the protection plate 120. When the protection plate 120 rotates to the open state 120b, the sliding block 1221 can abut against the end wall at the other end of the stroke groove 1131, so as to prevent the protection plate 120 from being excessively rotated to cause pressure loss on the elastic member 130.

In some embodiments, a limit plate is further disposed on the mounting seat 110 on the rotation path of the protection plate 120, for further limiting the rotation stroke of the protection plate 120. The mount 110 may be provided with a first limit plate 1121 and a second limit plate 114. When the protection plate 120 rotates to the protection state 120a, the first position-limiting plate 1121 can abut against a sidewall of one shielding portion 121, and the second position-limiting plate 114 can abut against a sidewall of another shielding portion 121, so as to limit the protection plate 120 from over-rotation. In some embodiments, the first limiting plate 1121 may be formed by a portion of the surrounding plate 112, and the second limiting plate 114 may be protruded from a side of the bottom plate 111 close to the surrounding plate 120.

Of course, in other embodiments, the second limiting plate 114 may be formed by a portion of the enclosure 112.

In some embodiments, the enclosure 112 further includes a third limiting plate 1122, and when the protection plate 120 rotates to the open state 120b, the shielding portion 121 abutting against the first limiting plate 1121 can abut against the third limiting plate 1122, so as to further limit the rotation stroke of the protection plate 120, and avoid the protection plate 120 from rotating excessively.

As shown in fig. 7 and 8, the second limiting plate 114 and the surrounding plate 112 may define a receiving cavity 115, and the elastic element 130 may be installed in the receiving cavity 115. It is understood that a side of the receiving cavity 115 adjacent to the mounting shaft 113 may be open so that the elastic member 130 is connected to the connection portion 122 of the guard plate 120.

In some embodiments, the resilient member 130 may be a spring. The elastic member 130 may be compressed between the mount 110 and the guard plate 120. Specifically, one end of the elastic member 130 can abut against the sidewall 1151 of the receiving cavity 115 at the end away from the mounting shaft 113. The other end of the elastic member 130 may abut against the connection portion 122 of the protection plate 120.
