Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1-11, the present application provides a false-touch prevention device that may be used in an electrical socket that includes a first housing 10 and a shutter assembly 60 connected above the first housing 10.

Referring to fig. 5 to 6, the first housing 10 includes a first insertion groove 11 and a second insertion groove 12 having an upper opening 14 according to an embodiment of the present invention. The first slot 11 and the second slot 12 have the same structure, and the first slot 11 and the second slot 12 can be both fixedly connected with a metal electrode sheet 13, and the metal electrode sheet 13 can be respectively electrically connected with the positive electrode and the negative electrode of the commercial power, so that when the metal electrode sheets 13 in the first slot 11 and the second slot 12 are contacted with each other by a metal foreign object, conduction is realized.

According to an embodiment of the present invention, referring to fig. 5, the shutter assembly 60 includes a shutter member 30, a spring member 32 connected to the shutter member 30 and a plurality of protrusions 33 provided on an upper surface of the shutter member 30, and a second housing 20 connected above the first housing 10 and a cover member 40 that can cover the second housing 20.

According to an embodiment of the present invention, referring to fig. 5 and 6, the shutter member 30 is movably connected above the first housing 10. Specifically, the shutter member 30 can rotate and translate relative to the first housing 10 and the second housing 20, and block the upper end openings 14 of the first slot 11 and the second slot 12 when rotating relative to the first housing 10, and open the upper end openings 14 of the first slot 11 and the second slot 12 when the shutter member 30 translates relative to the first housing 10.

Specifically, in one embodiment of the present invention, the shutter member 30 is adapted to rotate only with respect to the first housing 10 under the drive of a first external force. That is, when the first external force is applied to the shutter member 30, the shutter member 30 can only rotate, and the upper end openings 14 of the first and

second insertion grooves

11 and 12 are shielded by the shutter member 30. For example, when the first external force is a force accidentally applied to one of the insertion holes 42 of the electrical socket by a metal object, the rotation of the shutter member 30 can prevent the metal object from contacting the metal electrode sheet 13 in the first insertion groove 11 or the second insertion groove 12, thereby preventing an electric shock.

In one embodiment of the invention, the shutter member 30 is also adapted to translate only relative to the first housing 10 upon actuation by a second external force. That is, when the second external force is applied to the shutter member 30, the shutter member 30 can only translate but not rotate, so that the translation of the shutter member 30 opens the upper end openings 14 of the first slot 11 and the second slot 12. For example, when the second external force is an equalizing force simultaneously acting on the plurality of insertion holes 42 of the electrical socket through two, three or four pins 51 of the plug 50, the translation of the shutter member 30 can enable the plug 50 to be easily inserted into the first insertion groove 11 and the second insertion groove 12, and further, to contact the metal electrode pieces 13 in the first insertion groove 11 and the second insertion groove 12, so as to realize the energization.

Specifically, in one embodiment of the present invention, the first external force is a force applied solely to the left or right side of the shutter member 30. The second external force is an equalizing force applied to both the left and right sides of the shutter member 30. The first external force is sufficient to be applied by any foreign object applied to only one side of the gate member 30, while the second external force is any balancing force that can be applied to both the left and right sides of the gate member 30 at the same time. And are not intended to be limiting in any way.

Specifically, according to an embodiment of the present invention, referring to fig. 7-9, the second housing 20 is provided with a receiving groove 21 for receiving the shutter member 30. In the embodiment of the present invention, the height of the shutter member 30 is preferably lower than the depth of the accommodating tank 21, and the shutter member 30 can be translated and rotated at a small angle within the accommodating tank 21.

According to an embodiment of the present invention, referring to fig. 4-6, the second housing 20 is preferably connected above the first housing 10, and the bottom of the receiving groove 21 faces the upper openings 14 of the first slot 11 and the second slot 12. In the embodiment of the present application, the bottom of the receiving groove 21 is opened with a first opening 212 communicating with the first slot 11 and a second opening 213 communicating with the second slot 12. Further, in an unstressed state, the bottom of the shutter member 30 blocks the first opening 212 and the second opening 213, while when driven by a second external force, the shutter member 30 translates so that the first opening 212 and the second opening 213 are opened.

Referring to fig. 10-11, the shutter member 30 further defines a through slot 31 according to an embodiment of the present invention. The through-groove 31 is substantially similar in shape to the shutter member 30, and the through-groove 31 is located in the middle of the shutter member 30. In the embodiment of the present application, the bottom of the receiving groove 21 extends vertically upward to form the fixing member 22 that can pass through the through groove 31, so that the translation direction of the shutter member 30 can be defined.

According to one embodiment of the present invention, and as shown in FIGS. 7-8, the spring member 32 is preferably disposed horizontally between the retainer 22 and the gate member 30 for assisting in the translation and return of the gate member 30.

Specifically, in the embodiment of the present invention, as shown in fig. 4 and 7-11, the direction of elastic expansion and contraction of the spring member 32 is the same as the translational direction of the shutter member 30, and one end of the spring member 32 is connected to the fixing member 22, and the other end is connected to a groove wall of the through groove 31; here, the two opposing groove walls of the through groove 31 are set as a first groove wall 311 and a second groove wall 312, respectively, and the first groove wall 311 and the second groove wall 312 are set as two opposing groove walls perpendicular to the translational direction of the shutter member 30. Here, one end of the spring member 32 is fixedly connected to the fixing member 22, and the other end thereof is fixed to the first groove wall 311.

In another embodiment, one end of the spring element 32 is fixedly connected to the fixing element 22, and the other end thereof is connected to the first slot wall 311 in a limiting manner; specifically, in the embodiment, a fixing post 313 is formed on the first slot wall 311 extending toward the fixing element 22, and the other end of the spring element 32 is sleeved on the fixing post 313.

Specifically, in the embodiment of the present invention, under the driving of the second external force, the first slot wall 311 moves toward the fixed member 22, compressing the spring member 32. For example, when the plug 50 is inserted into an electrical socket by an external force, the latch 51 acts on both left and right sides of the shutter member 30, so that the shutter member 30 is translated while the spring member 32 is compressed, and the latch 51 can be tightly inserted into the first slot 11 and the second slot 12 by a reverse force generated after the spring member 32 is compressed, thereby preventing the occurrence of looseness.

According to an embodiment of the present invention, referring to fig. 10-11, two outer sidewalls of the shutter member 30 perpendicular to the translational direction of the shutter member 30 are a first outer sidewall 34 and a second outer sidewall 35, respectively. The first outer sidewall 34 is adjacent to the first groove wall 311 of the through groove 31. The second outer sidewall 35 is adjacent to the second slot wall 312 of the through slot 31.

In this embodiment, the second groove wall 312 is inclined and is formed with a first inclined surface 312 a. The first inclined surface 312a has a first inclined angle that is acute, and the left half of the first inclined surface 312a is narrow at the top and wide at the bottom of the shutter member 30. Here, the left half refers to a portion where the second outer sidewall 35 is located with the position of the projection 33 as a middle line (the projection 33 is preferably provided at a middle position of the upper surface of the shutter member 30).

In the present embodiment, the first outer sidewall 34 of the shutter member 30 is also disposed obliquely, and is formed with a second inclined surface 34 a. The second inclined surface 34a also has an acute second inclination angle, and the second inclined surface 34a also makes the right half of the shutter member 30 narrow upward and wide downward. The right half here refers to the side of the first outer side wall 34 with the projection 33 as the middle line.

In the present embodiment, the first inclined surface 312a and the second inclined surface 34a have the same inclination direction and inclination angle. That is, the first inclined surface 312a is parallel to the second inclined surface 34a, and the first inclined angle and the second inclined angle have the same magnitude.

In the present embodiment, in a state where the shutter member 30 is not subjected to a force, the first inclined surface 312a is preferably disposed directly above the first opening 212 and the first slot 11, and the second inclined surface 34a is preferably disposed directly above the second opening 213 and the second slot 12.

Further, when the second external force acts on the first inclined surface 312a and the second inclined surface 34a at the same time; the shutter member 30 translates. And the first external force acts on the first inclined surface 312a or the second inclined surface 34 a; the shutter member 30 is rotated.

According to an embodiment of the present application, please refer to fig. 3-5, the protrusion 33 is disposed on the upper surface of the shutter member 30, and is preferably located at the middle position of the solid portion of the upper surface of the shutter member 30, that is, the protrusion 33 is disposed on both sides or one side of the through slot 31, and in this embodiment, it is preferable that two protrusions 33 are disposed and located on both sides of the through slot 31.

In the present embodiment, the cover member 40 is covered on the second housing 20 such that the upper end of the receiving groove 21 is closed to form a receiving cavity for receiving the shutter member 30. When the cover member 40 is placed on the second housing 20, the top of the protrusion 33 contacts the inner surface 41 of the cover member 40. Thus, when the shutter member 30 rotates, the projection 33 can serve as an upper end fulcrum of the shutter member 30 to rotate with respect to the inner side surface 41 of the cover member 40. When the shutter member 30 is translated, the first inclined surface 312a and the second inclined surface 34a symmetrical to the protrusion 33 are simultaneously stressed, and the protrusion 33 can serve as a balance point to prevent the shutter member 30 from rotating.

According to an embodiment of the present application, referring to fig. 3-5, the upper surface 331 of the protrusion 33 is preferably arc-shaped, and more specifically, circular arc-shaped, so that the protrusion 33 can be used as a fulcrum to assist the rotation of the shutter member 30, and the contact area between the protrusion 33 and the inner side surface 41 of the cover member 40 can be reduced when the shutter member 30 translates.

According to an embodiment of the present application, when a first external force is applied to the shutter member 30, in order to facilitate the rotation of the shutter member 30, the lower surface of the shutter member 30 is preferably arched outward to form an arch portion 37, and an end point 38 (highest point) of the arch portion 37 is preferably located in the middle of the lower surface of the shutter member 30. In one embodiment, the outer surface of the raised portion 37 is preferably a circular arc surface. In another embodiment, the outer surface of the arch 37 is preferably a circular arc surface in the middle and symmetrically inclined surfaces on both sides.

In this embodiment, referring to fig. 3, the highest point of the arched portion 37 of the shutter member 30 is in direct contact with the groove bottom 211 of the accommodating groove 21, and can translate on the groove bottom 211 of the accommodating groove 21 or rotate on the groove bottom 211 of the accommodating groove 21.

In the embodiment of the present invention, for example, when a metal foreign object is inserted into one of the insertion holes 42 of the electrical socket, the front end of the metal foreign object contacts the first inclined surface 312a or the second inclined surface 34a of the shutter member 30 and applies a force to the first inclined surface 312a or the second inclined surface 34a, so that the shutter member 30 rotates in the accommodation groove 21, and at this time, the protrusion 33 having the circular arc outer surface rotates in contact with the inner side surface of the cover member 40, and the raised portion 37 having the circular arc outer surface rotates in contact with the groove bottom 211 of the accommodation groove 21. Thereby preventing the metal foreign object from entering the first slot 11 or the second slot 12, and further avoiding electric shock accidents.

For example, when the plug 50 is inserted into all the insertion holes 42 of the electrical outlet, the front end 52 of the plug pin 51 of the plug 50 simultaneously contacts the first inclined surface 312a and the second inclined surface 34a of the shutter member 30 and simultaneously applies force to the first inclined surface 312a and the second inclined surface 34a so that the shutter member 30 is translated in the accommodation groove 21. Here, the first contact point of the front end of the plug 51 with the first inclined surface 312a and the second contact point with the second inclined surface 34a are symmetrical with each other with respect to the protrusion 33, thereby preventing the left half and the right half of the shutter member 30 from being unevenly stressed. Further, the projection 33 having the circular arc outer surface is in translational contact with the inner side surface of the cover member 40, and the arcuate portion 37 having the circular arc outer surface is in translational contact with the groove bottom 211 of the accommodation groove 21. Further, the plug 51 of the plug 50 is allowed to enter the first socket 11 and the second socket 12 through the first opening 212 and the second opening 213 under the shutter member 30, thereby achieving electrical connection between the plug 50 and the electrical socket.

According to an embodiment of the present application, in order to ensure that the shutter member 30 does not translate while rotating, the lower surface of the shutter member 30 is further formed with a first step 310 and a second step 320, and the bottom of the receiving groove 21 is further provided with a first boss 214 and a second boss 215 corresponding to the first step 310 and the second step 320. In the embodiment of the present invention, when the shutter member 30 rotates, the first step 310 abuts on the first boss 214 or the second step 320 abuts on the second boss 215 to prevent the shutter member 30 from translating.

Specifically, in the embodiment of the present invention, for example, when a metal foreign object is inserted into one of the insertion holes 42 of the electrical socket, the front end of the metal foreign object contacts the first inclined surface 312a of the shutter member 30 and applies a force to the first inclined surface 312a, so that the shutter member 30 rotates in the accommodation groove 21, and the first projection 214 provided at the groove bottom 211 of the accommodation groove 21 abuts on the first step 310 on the lower surface of the shutter member 30, thereby preventing the shutter member 30 from translating. At this time, the protrusion 33 having the circular arc-shaped outer surface is in rotational contact with the inner side surface of the cover member 40, and the rising portion 37 having the circular arc-shaped outer surface is in rotational contact with the groove bottom 211 of the receiving groove 21. Thereby preventing the metal foreign object from entering the first slot 11 and further avoiding electric shock accidents.

For example, when a metal foreign object is inserted into the other insertion hole 42 of the electrical socket, the front end of the metal foreign object contacts the second inclined surface 34a of the shutter member 30 and applies a force to the second inclined surface 34a, so that the shutter member 30 rotates in the accommodation groove 21, while the second projection 215 provided at the groove bottom 211 of the accommodation groove 21 abuts on the second step 320 on the lower surface of the shutter member 30, thereby preventing the shutter member 30 from translating. At this time, the protrusion 33 having the circular arc-shaped outer surface is in rotational contact with the inner side surface of the cover member 40, and the rising portion 37 having the circular arc-shaped outer surface is in rotational contact with the groove bottom 211 of the receiving groove 21. Thereby preventing the metal foreign objects from entering the second slot 12 and further avoiding electric shock accidents.

Specifically, according to an embodiment of the present application, referring to fig. 10-11, the first step 310 is located at the bottom of the solid portion between the second groove wall 312 of the receiving groove 21 and the second outer sidewall 35 of the shutter member 30. Specifically, the first step 310 is located between the second outer sidewall 35 of the shutter member 30 and the bottom wall 39 of the shutter member 30, and is formed by removing material. That is, the first step 310 has one side opening on the second outer sidewall 35 and the other side opening on the bottom wall 39 of the shutter member 30.

The second step 320 is located at the bottom of the solid portion between the first groove wall 311 and the first outer side wall 34 of the shutter member 30. Specifically, the second step 320 is located between the first groove wall 311 of the receiving groove 21 and the bottom wall 39 of the shutter member 30, and is formed by removing material. That is, one side of the second step 320 is open on the first groove wall 311, and the other side is open on the bottom wall 39 of the shutter member 30.

Further, the first step 310 and the second step 320 are of the same height and are designed to ensure that neither of the first boss 214 nor the second boss 215 is in contact with the ram member 30 as it translates. That is, the first boss 214 and the second boss 215 provided at the groove bottom 211 of the accommodation groove 21 do not block the movement of the shutter member 30 during the translation of the shutter member 30.

Referring to fig. 1-3, in an embodiment of the present invention, there is further provided a socket, in which the aforesaid mis-touch prevention device is disposed, and the first external force is a force applied only to any one of the insertion holes 42 of the socket, that is, a force applied by a metal or non-metal foreign object to insert into one or more of the insertion holes 42 during abnormal insertion.
