Description

Protective door assembly for socket and socket

Technical Field

Embodiments of the present invention relate to a socket, and more particularly, to a protective door assembly for a socket.

Background

Sockets are widely used in everyday life and are adapted to receive plugs to take electricity from a power source. For safety and aesthetic reasons, sockets are often provided with protective doors for covering the jacks of the socket. When the plug is not inserted into the socket, the protective door covers the jack of the socket to prevent dust or decoration pollutants from entering the interior of the socket; when the plug is inserted into the socket, the protective door is removed to allow the pin to be inserted into the socket to establish electrical connection.

However, the protective door of the conventional outlet is not satisfactory. In particular, the protective door is liable to be moved by a user (e.g., a young adult who is naughty) to leak out of the terminal block to cause a safety hazard; for example, in some cases, a user may insert a wand into a receptacle to open a protective door, which is undesirable. Accordingly, it is desirable to improve the protective door of the conventional outlet.

Disclosure of Invention

In view of the above, it is an object of the embodiments of the present disclosure to provide a protective door assembly for a socket and a socket, which can solve or alleviate at least one of the problems described above.

According to one aspect of the present invention, a protective door assembly for a receptacle is provided. The protective door assembly includes: an LN pole protective door comprising an LN pole protective face adapted to cover an L pole jack and an N pole jack of the receptacle, wherein the LN pole protective door is configured to be floatingly mounted with respect to a base of the receptacle; and a bracket provided separately from the LN pole protection door and including an E pole portion including a first inclined portion adapted to be disposed at an E pole insertion hole of the socket, the first inclined portion being configured to be pushed by a pin inserted into the E pole insertion hole so that the bracket moves in a direction perpendicular to an insertion direction.

According to the protective door assembly of the embodiment of the present disclosure, the cradle and the LN pole protective door are provided independently, and the movement of the cradle and the movement of the LN protective door are independent of each other. Thereby, more effective safety protection can be provided for the socket. Furthermore, since the LN pole shutter is floatingly mounted with respect to the base of the receptacle, it is thereby possible to make the LN pole shutter abut the mounting panel to provide protection when the pin is not inserted into the jack, while providing freedom of movement when the LN pole shutter is inserted by the pin to allow the LN pole shutter to achieve the desired evasive movement.

According to one embodiment of the present disclosure, the shutter assembly may further comprise a resilient retainer adapted to cooperate with the LN pole shutter, configured to apply a force to the LN pole shutter towards the mounting panel of the receptacle, such that the LN pole shutter resiliently abuts horizontally against the mounting panel of the receptacle. Thus, the LN pole protection door can be always kept elastically horizontally abutting against the mounting panel by the elastic holder to provide protection for the outlet.

According to an embodiment of the present disclosure, the elastic holder may include one of: a needle, a finger, a sheet, or a combination thereof. According to an embodiment of the present disclosure, the LN pole protection door may comprise a guiding groove or a guiding hole adapted to mate with the resilient retainer.

According to an embodiment of the present disclosure, the shutter assembly may further include an elastic reset member configured to be compressed in response to a movement component of the LN pole shutter in a direction perpendicular to the insertion direction and to reset the LN pole shutter in response to the L and N pole pins of the plug being pulled out from the L and N pole jacks. Thus, when the LN pole protection door moves, the elastic reset piece is used for accumulating energy; when the force is removed, the elastic reset piece is used for resetting. In some embodiments, the resilient return member comprises a torsion spring. This allows a simple assembly and arrangement of the elastic return element.

According to one embodiment of the present disclosure, the elastic retainer and the elastic return member are formed as an integral component. Thus, the number of parts can be reduced, and the manufacturing cost can be reduced.

According to one embodiment of the present disclosure, the protective door assembly further comprises a positioning member that positions the resilient retainer in a predetermined orientation relative to the LN pole protective door. In some embodiments, the positioning member, the resilient retainer and the resilient return member are an integral component. According to one embodiment of the present disclosure, the positioning member may include spring coil turns formed in a polygonal shape.

According to an embodiment of the present disclosure, the LN pole protection door may include a support groove extending in a direction perpendicular to the insertion direction, adapted to cooperate with a cross beam mounted on a base of the receptacle so as to deflect around the cross beam when the LN pole protection face is pushed by an object inserted into only one of the L-pole insertion hole and the N-pole insertion hole. Thereby, even if a single object is inserted into only one of the L-pole jack and the N-pole jack, effective protection can be provided.

According to one embodiment of the present disclosure, the LN pole protective door can include an abutment adapted to abut the base when the LN pole protective face deflects about the cross beam to limit an amount of deflection of the LN pole protective door. Thus, excessive deflection of the LN pole protection door can be prevented.

According to an embodiment of the present disclosure, the LN pole protection door may include a second inclined portion adapted to be fitted on the base of the receptacle such that when the LN pole protection face is pushed by the pins inserted into the L-pole and N-pole receptacles, the second inclined portion moves along the base to provide a force component that moves the LN pole protection door in a direction perpendicular to the insertion direction.

According to an embodiment of the present disclosure, the protective door assembly may further include an E-pole protective door pivotably mounted to the bracket and may include an E-pole protective face adapted to cover an E-pole receptacle of the socket, wherein the E-pole protective door is configured to pivot toward the E-pole portion to push the first inclined portion in response to insertion of a pin of the E-pole receptacle.

According to one embodiment of the present disclosure, the E-pole protective door may include a pair of shafts extending from sides thereof, and the E-pole may include a pair of holes adapted to receive and mate with the pair of shafts.

According to one embodiment of the present disclosure, the protective door assembly may further include a resilient retainer adapted to cooperate with the E-pole protective door, configured to apply a force to the E-pole protective door toward the mounting panel of the receptacle to resiliently horizontally abut the E-pole protective door against the mounting panel.

According to an embodiment of the present disclosure, the elastic holder may include one of: a needle, a finger, a sheet, or a combination thereof.

According to an embodiment of the present disclosure, the E-pole portion may comprise a guiding groove or a guiding hole adapted to mate with the resilient holder.

According to an embodiment of the present disclosure, the protective door assembly may further include an elastic restoring member configured to be compressed in response to the movement of the bracket and to restore the bracket in response to the pin being withdrawn from the E-pole receptacle. In some embodiments, the resilient return member may comprise a torsion spring.

According to one embodiment of the present disclosure, the elastic retainer and the elastic return member are formed as an integral component.

According to one embodiment of the present disclosure, a protective door assembly may include a positioning member adapted to position the resilient retainer in a predetermined orientation relative to the E-pole protective door. In some embodiments, the positioning member, the resilient retainer and the resilient return member are an integral component. According to one embodiment of the present disclosure, the positioning member may include spring coil turns formed in a polygonal shape. According to one embodiment of the present disclosure, the positioning member may include spring coil turns formed in a polygonal shape.

According to an embodiment of the present disclosure, the bracket may further include a hollow portion providing a mounting space for the elastic restoring member.

According to an embodiment of the present disclosure, the protective door assembly may further include a movement blocking portion provided on at least one of the LN pole protective door and the bracket, and configured to: before the carriage moves, the LN pole shutter can abut against the carriage when pressed to prevent the LN pole shutter from moving.

According to an embodiment of the present disclosure, the movement blocking portion may include a boss provided on one of the LN pole protection door and the cradle, and a recess provided on the other of the LN pole protection door and the cradle to be fitted with the boss.

Detailed Description

Embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the same reference numerals may be used in the drawings for similar components or functional elements. The accompanying drawings are only intended to illustrate embodiments of the present disclosure. Those skilled in the art will recognize that alternative embodiments can be made from the following description without departing from the spirit and scope of the disclosure.

The structure of the receptacle and shutter assembly of the embodiment of the present disclosure will be described in detail with reference to fig. 1 to 5. Although embodiments of the present disclosure are described with respect to a three-jack receptacle, it should be understood that the concepts of the present disclosure may also be used in other receptacles including three-jack receptacles, such as five-jack receptacles, and the like.

As shown in fig. 1, the socket 1 may include a bezel 50, a mounting panel 30, a protective door assembly, and a base 40. The frame 50 may form a decorative surface of the socket 1. The base 40 can house therein respective pole electrical contact pieces electrically connected to power and can be fixed to a wall or the like. The mounting panel 30 may cover the base 40 after wiring is completed to provide protection for the electrical components within the base. The mounting panel 30 may include an E-pole receptacle 36 adapted to receive an E-pole pin of a plug, an L-pole receptacle 34 of an L-pole pin of a plug, and an N-pole receptacle 32 of an N-pole pin of a plug. After the pins enter the receptacles of the mounting panel 30, electrical contact may be made with the terminals within the base 40 to draw power from the power source. Since these components are well known to those skilled in the art, a detailed description thereof will be omitted.

The protective door assembly may include a LN pole protective door 10 and a bracket 20. LN pole protective door 10 can include LN pole protective face 16 (see fig. 6). In the case where the LN pole protection door 10 is attached to the installation panel 30, the LN pole protection face can cover the L pole insertion hole 34 and the N pole insertion hole 32 of the outlet. In the disclosed embodiment, LN pole protection door 10 is configured to be floatingly mounted with respect to the base of the receptacle. In some embodiments, the LN pole protection door 10 may be floatingly supported via a spring 60 provided in the receptacle, and may elastically abut horizontally against the mounting panel 30.

As shown, the bracket 20 is provided independently of the LN pole protection door 10. The bracket 20 may include an E-pole portion 25, the E-pole portion 25 including a first inclined portion 24 adapted to be disposed at an E-pole insertion hole 36 of the socket, the first inclined portion 24 being configured to be pushed by a pin inserted into the E-pole insertion hole 36 such that the bracket 20 moves in a direction perpendicular to the insertion direction. Thereby, the bracket 20 is pushed to move by the pushing of the E pole pin. In some embodiments, the bracket 20 may provide the functionality of an E-pole protective door.

In the protective door assembly according to the embodiment of the present disclosure, the cradle 20 is provided independently of the LN pole protective door 10, and the movement of the cradle 20 and the movement of the LN protective door 10 are independent of each other. Thereby, more effective safety protection can be provided for the socket. Further, since LN pole protection door 10 is floatingly mounted with respect to the base of the receptacle, it is possible to make LN pole protection door 10 abut against the mounting panel to provide protection when the pin is not inserted into the jack, while providing freedom of movement when LN pole protection door 10 is inserted by the pin to allow LN pole protection door 10 to achieve a desired escape movement.

Fig. 2 and 3 show schematic structural diagrams of LN pole protective doors according to embodiments of the present disclosure.

The LN pole protection door 10 can elastically abut against the installation panel 30. LN pole protective door 10 can be responsive to

The LN pole protection door 10 is simultaneously abutted by the L pole pin and the N pole pin and retreats to avoid the moving paths of the L pole pin and the N pole pin.

In the illustrated embodiment, LN pole protective door 10 can include a resilient retainer 62 adapted to cooperate with LN pole protective door 10. The elastic holder 62 is configured to apply a force to the LN pole protection door 10 toward the mount panel 30 of the receptacle so that the LN pole protection door 10 elastically abuts against the mount panel 30 of the receptacle.

In some embodiments, the resilient retainer 62 may comprise one of: a needle, a finger, a sheet, or a combination thereof. In the illustrated embodiment, the resilient retainer 62 is in the form of a needle. The resilient retainer 62 may provide a resilient support beam function for the LN pole protective door 10 to maintain the LN pole protective door 10 in a predetermined orientation. Forming the resilient retainer 62 in the form of a needle may reduce material usage and have the advantage of ease of processing. It should be understood that the shape of the elastic holder 62 is not limited in any way as long as the function of the elastic support beam can be provided.

In some embodiments, LN pole protective door 10 can include a guide slot or hole 12 adapted to mate with resilient retainer 62. Thereby, the movement of the elastic holder 62 can be prevented, and the LN pole protection door 10 is reliably supported.

In some embodiments, LN pole protective door 10 can include resilient return 64. The elastic reset piece 64 is configured to be compressed in response to a movement component of the LN pole protection door 10 in a direction perpendicular to the insertion direction and to reset the LN pole protection door 10 in response to the L and N pole pins of the plug being pulled out from the L pole insertion hole 34 and the N pole insertion hole 32. In particular, in the illustrated embodiment, when LN pole protective door 10 is moved by a horizontal force component (in FIG. 3), elastic return member 64 will be compressed; when the horizontal force component disappears (for example, when the LN pole pin is pulled out), the LN pole protective door 10 is reset by the elastic reset piece 64. In the illustrated embodiment, the resilient return member 64 may comprise a torsion spring. LN pole protection door 10 may include a mounting portion of a spring to which elastic return 64 may be mounted at one end; the other end of the elastic restoring member 64 may be mounted to the mounting panel 30.

In the illustrated embodiment, the resilient retainer 62 and the resilient return 64 are an integral component, i.e., part of the spring 60. This can reduce the number of parts and manufacturing costs. It should be understood that this is merely exemplary. In other embodiments, the resilient retainer 62 and the resilient return 64 may be separate components, although this may increase cost.

In the illustrated embodiment, the resilient member may further comprise a positioning member 66 adapted to bring the resilient retainer 62 into a predetermined orientation with respect to the LN pole protection door 10. In the illustrated embodiment, the positioning member 66 may include spring coil turns formed in a polygonal shape. Since the polygonal spring coil turns can provide a stable orientation for the resilient member, it can be ensured that the positioning member 66 always maintains a predetermined orientation. In some embodiments, the mounting panel 30 may include a mounting slot (not shown) adapted to mount the positioning member 66, whereby the positioning member 66 may be retained in the mounting slot in a predetermined orientation.

In the illustrated embodiment, the LN pole protection door 10 may include a second slope 14 (see fig. 6 and 9). Via the second slope 14, it is possible to provide guidance for movement of the LN pole protection door 10 and provide a horizontal movement force for the LN pole protection door 10. The second slanted portion 14 is adapted to fit on the base 40 of the receptacle so that when the LN pole protection face 16 is pushed by the pins inserted into the L-pole insertion hole 34 and the N-pole insertion hole 32, the second slanted portion 14 moves along the base 40 to provide a force component that moves the LN pole protection door 10 in a direction perpendicular to the insertion direction. It is worth mentioning that although in the illustrated embodiment the second inclined portion 14 is implemented in the form of an inclined surface, this is merely exemplary and the second inclined portion 14 may be implemented in other shapes capable of providing a horizontal force component. In addition, the position of the second inclined portion 14 is also merely exemplary and may be adjusted according to the structure of the socket. In the illustrated embodiment, the base 40 of the socket may include a portion that mates with the second angled portion 14, such as angled portion 46. The inclined portion 46 is similar to the second inclined portion 14, and its shape and position are not limited.

In the illustrated embodiment, the LN pole protection door 10 may include a support groove 15 extending in a direction perpendicular to the insertion direction. The support slot 15 may cooperate with a cross bar 44 mounted on the base 40 of the receptacle. Thus, when the LN pole protection face 16 is pushed by being inserted into only one of the L pole insertion hole 34 and the N pole insertion hole 32, the LN pole protection door 10 can be deflected around the cross member 44. Thereby, the socket can be further protected.

In the illustrated embodiment, the LN pole protection door 10 can include an abutment 18 adapted to abut the pedestal 40 to limit the amount of deflection of the LN pole protection door 10 as the LN pole protection face deflects about the cross beam 44.

In the illustrated embodiment, the protective door assembly may further include a movement stopper 22, the movement stopper 22 being provided on at least one of the LN pole protective door 10 and the cradle 20, and configured to: before the movement of the cradle 20, the LN pole protection door 10 can abut against the cradle 20 when pressed to prevent the movement of the LN pole protection door 10. In some embodiments, the movement blocking portion 22 may include a boss provided on one of the LN pole protection door 10 and the bracket 20 and a recess 19 provided on the other of the LN pole protection door 10 and the bracket 20 to be fitted with the boss.

Although in the illustrated embodiment, the movement preventing portion 22 is provided on the bracket 20 in the form of a convex portion, the LN pole protection door 10 includes a concave portion 19 that matches the convex portion. With such a structure, the thickness and/or size of the socket can be effectively reduced. It should be understood that this is merely exemplary. Any other suitable form may be used for the purpose of the LN pole protection door 10 and the bracket 20 abutting each other.

Fig. 4 and 5 show schematic structural views of the stand 20 and the base 40 according to an embodiment of the present disclosure. The bracket 20 may provide the function of an E-pole protective door. In some embodiments, the stand 20 is mounted in the base 40 with a spring 70 and may be retained via a guide wall 42 provided on the base 40. The bracket 20 may be configured to horizontally move in response to the depression of the E-pole pin inserted into the E-pole socket, thereby avoiding a moving path of the E-pole pin.

In the illustrated embodiment, the bracket 20 may be provided with an E-pole protective door 28. The E-pole protection door 28 is pivotally mounted to the bracket 20. The E-pole protective door 28 may include an E-pole protective face adapted to cover the E-pole receptacle 36 of the receptacle. By providing the E-pole protective door 28 to provide an E-pole protective surface, the aesthetics of the receptacle can be improved. It should be understood that this is merely exemplary, and in other embodiments, the bracket 20 may not be provided with the E-pole protection door 28 and may provide an E-pole protection surface by its own structure (e.g., may be provided by the first angled portion 24). In this case, the first inclined portion 24 may be sized and shaped to provide an E-pole protective surface.

In the illustrated embodiment, the E-pole protective door 28 may be configured to pivot toward the E-pole portion 25 to push the first angled portion 24 in response to insertion of a pin of the E-pole receptacle 36. Thereby, the moving bracket 20 is horizontally moved by a horizontal force component acting on the first inclined part 24, thereby avoiding the moving path of the E-pole pin.

In the illustrated embodiment, the E-pole protective door 28 can include a pair of shafts 282 extending from sides thereof, and the E-pole portion 25 can include a pair of holes 252 adapted to receive and mate with the pair of shafts 282. Thus, the E pole protection door 28 can be conveniently installed by shaft hole fitting. It should be understood that such a shaft-hole fit is merely exemplary, and that other means known in the art may be used to implement the pivotable structure of the E-pole protective door 28.

In the illustrated embodiment, where an E-pole protective door 28 is provided, a resilient retainer 72 adapted to cooperate with the E-pole protective door 28 may also be provided. The elastic holder 72 is configured to apply a force to the E-pole protection door 28 toward the mounting panel 30 of the receptacle so that the E-pole protection door 28 elastically abuts against the mounting panel 30. This can always ensure the floating arrangement of the E-pole protection gate 28.

In some embodiments, the resilient retainer 72 may include one of: a needle, a finger, a sheet, or a combination thereof. In the illustrated embodiment, the resilient retainer 72 is in the form of a needle. The resilient retainer 72 may provide a resilient support beam for the E-pole protective door 28 to maintain the E-pole protective door 28 in a predetermined orientation. Forming the resilient retainer 72 in the form of a needle may reduce material usage and have the advantage of ease of processing. It should be understood that the shape of the elastic holder 72 is not limited in any particular way as long as the function of the elastic support beam can be provided.

In some embodiments, the E-pole portion 25 may include a guide slot or hole adapted to mate with the resilient retainer 72. Thus, the movement of the elastic holder 72 can be prevented, and the E-pole protection door 28 can be reliably supported.

In some embodiments, a resilient return 74 may also be included. The resilient return member 74 is configured to be compressed in response to movement of the carrier 20 and to return the carrier 20 in response to the E-pole pin being withdrawn from the E-pole receptacle 36. In particular, in the illustrated embodiment, when the E-pole protective door 28 is pressed down by the E-pole pin to abut against the first inclined portion 24, the first inclined portion 24 is acted upon by a horizontal force component to urge the bracket 20 to move horizontally, thereby compressing the resilient return member 74; when the horizontal force component disappears (e.g., when the E-pole pin is pulled out), the cradle 20 is reset by the elastic reset member 74. In the illustrated embodiment, the resilient return member 64 may comprise a torsion spring. The E-pole section 25 may include a mounting portion of a spring to which the resilient return 74 may be mounted at one end; the other end of resilient return 74 may be mounted to base 40.

In the illustrated embodiment, the resilient retainer 72 and the resilient return 74 are formed as an integral component, i.e., part of the spring 70. This can reduce the number of parts and manufacturing costs. It should be understood that this is merely exemplary. In other embodiments, the resilient retainer 72 and the resilient return 74 may be separate components, although this may increase cost.

In the illustrated embodiment, the resilient member may further include a positioning member 76 adapted to position the resilient retainer 72 in a predetermined orientation relative to the E-pole protective door 28. In the illustrated embodiment, the positioning member 76 may include spring coil turns formed in a polygonal shape. Since the polygonal spring coil turns can provide a stable orientation for the resilient member, it can be ensured that the positioning member 76 always maintains a predetermined orientation. In some embodiments, the base 40 may include a mounting slot adapted to mount the positioning member 76, whereby the positioning member 76 may be retained in the mounting slot in a predetermined orientation.

In the illustrated embodiment, the holder 20 may further include a hollow portion 27, and the hollow portion 27 provides a mounting space for the elastic restoring member. Thereby, the component arrangement of the socket can be optimized, and the size of the socket can be reduced.

The normal operation of the receptacle and protective door assembly according to embodiments of the present disclosure is described below in conjunction with fig. 6-9. It should be understood that this is merely an exemplary description and that corresponding operational procedures may be provided for different embodiments.

Fig. 6 and 7 are schematic diagrams illustrating a first state of the process in which the E-pole pin 92 of the plug is about to be inserted into the E-pole receptacle. As shown in fig. 6 and 7, before the E-pole pin 92 is inserted into the E-pole insertion hole, the E-pole protective door 28 is held in contact with the bottom surface of the mounting panel 30 by the elastic holder 72 of the spring 70. In this state, the E-pole protective face of the E-pole protective door 28 covers the E-pole receptacle to provide protection for the receptacle. Similarly, the LN pole protection door 10 is held in abutment with the bottom surface of the mount panel 30 by the elastic holder 62 of the spring 60. In this state, the E-pole protection face 16 of the LN pole protection door 10 covers the LN pole jack to provide protection for the outlet. The inclined portion 14 of the LN pole protection door 10 and the mating portion (the inclined portion 46 in the drawing) of the base 40 do not move relatively, and are spaced apart by a predetermined distance.

Fig. 8 and 9 show schematic views of a second state in which E-pole pin 92 of the plug has been inserted into the E-pole receptacle and LN-pole pin 94 has begun to be inserted into the LN-pole receptacle. As shown in fig. 8 and 9, as the E-pole pin 92 is gradually moved downward while being continuously inserted into the E-pole insertion hole, the E-pole protective door 28 first leaves the bottom surface of the mounting panel 30 against the action of the elastic holder 72 of the spring 70 and pivots downward until the E-pole protective door 28 abuts against the first inclined surface 14 of the E-pole portion of the bracket 20. As the E-pole pin 92 continues to be depressed, the E-pole protective door 28 pushes against the first inclined surface 14 and will provide a horizontal force component to the first inclined surface 14, thereby pushing the bracket 20 to move rearward (in the leftward direction in the figure) against the action of the resilient return 74 of the spring 70. At this time, LN pole pin 94 starts to abut LN pole protection surface 16 of LN pole protection door 10. The LN pole protective face 16 is floatingly disposed relative to the base 40, and the LN pole protective face 16 will rotate downward in response to the downward pressure of the LN pole pin 94 and away from the bottom surface of the mounting panel 30 against the action of the resilient retainer 62 of the spring 60; the second inclined portion 14 of the LN pole protection door 10 is thereby caused to abut against the inclined portion 46 of the base 40, and is moved rearward (leftward in the drawing) by the action of the horizontal force component acting on the second inclined portion 14 and against the action of the elastic restoring piece 64 of the spring 60, thereby avoiding the downward movement path of the LN pole pin 94.

The following description, in conjunction with fig. 6-10, describes the operation of the outlet and shutter assembly according to an embodiment of the present disclosure during abnormal insertion, i.e., when a user inserts an object (e.g., a stick) into the outlet instead of a three-prong plug. It should be understood that this is merely an exemplary description and that corresponding operational procedures may be provided for different embodiments.

When a user inserts an object into only the E-pole jack, as described above with respect to fig. 8 and 9, the E-pole protective door 28 will move downward in response to the force of the object, thereby pushing the first inclined surface 14 of the bracket 20, and thereby pushing the bracket 20 to move backward (leftward in the drawing) against the elastic restoring member 74 of the spring 70. At this time, since no object is inserted into the LN pole jack, the LN pole protection face 16 will remain in abutment against the mounting panel 30 without moving, thereby providing protection to the LN pole of the receptacle. At this time, if the user moves the object out of the E-pole jack, the cradle 20 moves forward (rightward in the drawing) by the elastic restoring member 74 of the spring 70, thereby restoring the cradle 20; at the same time, the E-pole protection door 28 will be held against the mounting panel 30 by the resilient return 72 of the spring 70, thereby providing protection for the E-pole of the receptacle.

When a user inserts an object into only one of the L-pole jack and the N-pole jack, as shown in fig. 10, one side of the LN pole protection face 16 of the LN pole protection door 10 will move downward in response to the force of the object, and since the LN pole protection door 10 is provided floating with respect to the base and supported via the cross member 44, the LN pole protection door 10 will deflect with respect to the base, thereby preventing the LN pole of the outlet from leaking out. Further, when the contact portion 18 is provided in the LN pole protection door 10, the contact portion 18 of the LN pole protection door 10 can contact the pedestal 40, and the deflection of the LN pole protection door 10 is further restricted. Thereby, the socket can be further protected.

When a user inserts an object into two of the L-pole jack and the N-pole jack without inserting the E-pole jack, as shown in fig. 1 and 7, the LN pole protection face 16 of the LN pole protection door 10 will move downward in response to the force of the object. On the other hand, since the holder 20 is not moved, the LN pole protection door 10 can abut against the holder 20 when pressed, to prevent the LN pole protection door 10 from moving. Thus, protection can be provided for the socket.
