Description

Socket with improved structure

Technical Field

The present disclosure relates to the field of electrical equipment technology, and more particularly, to a socket.

Background

The socket is used for matching with the plug to realize the function of electric connection. For safety reasons, a misplug prevention function may be provided in the socket. For example, a protection component may be provided in the socket, so that when an inappropriate plug or foreign object is inserted into the socket, the protection component may block the plug or foreign object from entering the socket to avoid creating a safety hazard.

However, current anti-misplug receptacles have a number of problems. Some sockets are complicated in construction or principle to prevent erroneous insertion, resulting in poor reliability. When an improper plug or foreign object is inserted into such a socket, the protection assembly may be out of order or damaged if the force is large.

Disclosure of Invention

To at least partially address the above and other potential problems, embodiments of the present disclosure provide an improved receptacle.

According to an aspect of the present disclosure, there is provided a socket including: the device comprises a shell, a positioning part and a control part, wherein the shell is provided with a fire wire hole, a zero wire hole and a ground pole hole, and the inner side of the shell is provided with the positioning part; and a sliding door provided in the housing, the sliding door including: a body part disposed below the live wire hole and the neutral wire hole to enclose the live wire hole and the neutral wire hole, and configured to be slidable in a first direction to open the live wire hole and the neutral wire hole under an external force applied by the live wire pin and the neutral wire pin; a locking portion adapted to abut against the stopper portion to prevent the body portion from sliding in the first direction; and an unlocking part disposed below the ground pole hole and configured to be movable in a second direction intersecting the first direction by an external force applied by the ground pole pin to drive the sliding door to integrally rotate so that the locking part is disengaged from the stopper part.

In the embodiment of the present disclosure, by providing the sliding door with the lock portion and the unlock portion, it is possible to reliably lock the sliding of the sliding door and cancel the slide restriction of the sliding door in a simple integral turning manner. In addition, the sliding door of the embodiment of the disclosure is not easy to deform and damage, and the service life and reliability of the socket are increased.

In certain implementations of the present disclosure, the inside of the housing is further provided with at least one first protrusion and at least one second protrusion, and wherein the body portion is configured to be able to rotate clockwise and abut against the at least one first protrusion under an external force exerted by the live pin, or to rotate counterclockwise and abut against the at least one second protrusion under an external force exerted by the neutral pin, to limit the body portion from sliding in the first direction. By providing the first and second projections, the sliding door is prevented from sliding open the firing and neutral holes in the event that any two of the jacks (whether or not ground holes are included) are plugged with pins.

In certain implementations of the present disclosure, the housing includes a cover provided with a fire hole, a neutral hole, and a ground hole, and a base accommodating the conductive contact piece, wherein the limiting portion is provided on the cover, and the at least one first protrusion includes one first protrusion provided on the cover and another first protrusion provided on the base, and the at least one second protrusion includes one second protrusion provided on the cover and another second protrusion provided on the base. By this implementation, the stopper portion may be formed on the housing on the side of the insertion hole, which is more advantageous to the arrangement of the sliding door. In addition, the plurality of bulges are respectively formed on the cover body and the base, so that the sliding of the sliding door can be limited at a plurality of positions, and the reliability of the socket is further improved.

In certain implementations of the present disclosure, the body portion includes a first ramp and a second ramp disposed on a top side of the body portion facing the wire and neutral apertures. By this implementation, the downward force of the plug can be effectively converted into a force that urges the sliding door to slide.

In certain implementations of the present disclosure, the housing includes a sliding track, and the body portion includes a sliding slot that cooperates with the sliding track, the sliding slot being disposed in a middle of a bottom side of the body portion facing away from the live and neutral holes. In this implementation, the sliding of the sliding door can be facilitated by the sliding rail and the sliding groove, and the sliding door can rotate by taking the sliding rail and the sliding groove as a fulcrum.

In certain implementations of the present disclosure, the receptacle further comprises: a spring coupled to the housing and the sliding door, the spring configured to bias the sliding door in a direction opposite to the first direction. In this implementation, the resilient member can drive the sliding door back to the locked position after the plug is disengaged from the receptacle.

In certain implementations of the present disclosure, the resilient member is further configured to bias the sliding door in a direction opposite the second direction. In this way, it is advantageous to bias the locking portion of the sliding door in a position locked by the stopper portion, and it is also possible to ensure that the sliding door can move back and forth along a route parallel to the first direction after being unlocked.

In certain implementations of the present disclosure, the limit stop is provided with a ramp inclined with respect to the first direction. In this way, the stopper portion can be prevented from blocking the sliding door when the sliding door is reset.

In certain implementations of the present disclosure, the housing further comprises: a first blocking part disposed at a distance from the unlocking part and configured to block the unlocking part after the unlocking part moves a certain distance toward the second direction; and a second blocking portion adjacent to the body portion and configured to block the body portion in a direction opposite to the first direction.

In certain implementations of the present disclosure, wherein the sliding door further includes a bar-shaped hole and a biasing portion adjacent to the locking portion, wherein the cover is provided with a post passing through the bar-shaped hole and extending to a lower side of the sliding door, and the elastic member is coupled between a portion of the post located below the sliding door and the biasing portion.

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the disclosure, nor is it intended to be used to limit the scope of the disclosure.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Alternative embodiments will become apparent to those skilled in the art from the following description without departing from the spirit and scope of the disclosure.

The term "include" and variations thereof as used herein is meant to be inclusive in an open-ended manner, i.e., "including but not limited to". Unless specifically stated otherwise, the term "or" means "and/or". The term "based on" means "based at least in part on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". Other explicit and implicit definitions are also possible below.

Embodiments of the present disclosure provide a novel socket. In this socket, the sliding door can be locked in one direction by the locking portion and the stopper portion, and the ground pin can rotate the sliding door in the other direction to unlock the sliding door. Thereby, locking and unlocking of the sliding door can be achieved simply and reliably, ensuring proper plug insertion into the triple-hole receptacle.

Fig. 1 shows a cross-sectional view of a receptacle 100 and a plug 200 according to an embodiment of the present disclosure. According to an embodiment of the present disclosure, the socket 100 includes a housing 110, the housing 110 is provided with a live hole 111, a neutral hole 112, and a ground hole 113 (the live hole 111, the neutral hole 112 refer to fig. 5A and 5B), and an inner side of the housing 110 is provided with a stopper 114. As an example, the socket 100 is a three-hole socket, and thus a live hole 111, a neutral hole 112, and a ground hole 113 into which a three-pin plug is inserted are provided on the housing 110. As an example, the stopper portion 114 may be provided inside the case 110 and formed as a protrusion protruding toward the inner cavity of the case 110.

According to an embodiment of the present disclosure, the socket 100 includes a sliding door 120 disposed within the housing 110. Fig. 2A and 2B illustrate perspective views of the sliding door 120 according to an embodiment of the present disclosure, and fig. 2C illustrates a front view of the sliding door 120 according to an embodiment of the present disclosure. As an example, the sliding door 120 may be integrally formed in a T-like shape to extend under three insertion holes of the socket 100.

Referring to fig. 1 and 2A to 2C, the sliding door 120 includes a body part 121, the body part 121 is disposed below the live and

neutral holes

111 and 112 for closing the live and

neutral holes

111 and 112, and the body part 121 is configured to be slidable in a first direction D1 under an external force applied by the live and neutral pins to open the live and

neutral holes

111 and 112. Specifically, the body portion 121 is positioned below the live and

neutral holes

111, 112 to enclose the live and

neutral holes

111, 112 to separate the interior of the jack 100 from the exterior when the plug 200 is not yet inserted into the jack 100. When the plug 200 is inserted into the fire wire hole 111 and the neutral wire hole 112, the fire and neutral pins of the plug 200 will contact the body portion 121 and apply a force to the body portion 121. If the sliding door 120 is unlocked, such force will cause the body portion 121 to slide in the first direction D1 to another position, thereby opening the previously closed power and

neutral apertures

111, 112, causing the power and neutral pins of the plug 200 to move further inward of the socket 100 to eventually contact the conductive contacts within the socket 100, thereby electrically connecting the power and neutral.

In some embodiments of the present disclosure, body portion 121 includes a first ramp 1211 and a second ramp 1212, the first ramp 1211 and the second ramp 1212 disposed on a top side of body portion 121 facing hot and

neutral apertures

111, 112. Specifically, during insertion of the hot and neutral pins of the plug 200 into the receptacle 100, the hot pin will contact the first ramp 1211 and the neutral pin will contact the second ramp 1212. When downward pressure of the plug 200 is applied to the first and

second slopes

1211 and 1212, a pushing force pushing the sliding door 120 or the body portion 121 in the first direction D1 is generated. Thus, the ramp configuration on the body portion 121 can effectively convert the downward force of the plug 200 into a force that causes the sliding door 120 to slide.

According to an embodiment of the present disclosure, the sliding door 120 includes a locking portion 123, and the locking portion 123 is adapted to abut against the stopper portion 114 to prevent the body portion 121 from sliding in the first direction D1. As an example, the locking part 123 may be provided at the other end of the sliding door 120 with respect to the body part 121, and may be formed in a convex shape. The stopper portion 114 may face the locking portion 123 in a direction opposite to the first direction D1, thereby restricting the sliding of the sliding door 120 toward the first direction D1, thereby effectively locking the body portion 121 of the sliding door 120 at a position closing the fire wire hole 111 and the neutral wire hole 112. It will be appreciated that the locking portion 123 and the position limiting portion 114 may be other suitable structures that perform the position limiting function. For example, the locking portion 123 may be a recess, and the stopper 114 is a projection that can be fitted into the recess; or the stopper portion 114 may be a concave portion and the lock portion 123 is a convex portion that can be fitted into the concave portion.

According to an embodiment of the present disclosure, the sliding door 120 includes an unlocking part 124, and the unlocking part 124 is disposed below the ground pole hole 113 and configured to be movable in a second direction D2 intersecting the first direction D1 by an external force applied by the ground pole pin to drive the sliding door to integrally rotate such that the locking part 123 is disengaged from the stopper part 114. As an example, the unlocking part 124 may be disposed adjacent to the locking part 123 at an end of the sliding door 120, and thus below the ground pole hole 113. When the ground pin is inserted into the ground hole 113 and pushes the unlocking part 124 toward the second direction D2, the sliding door 120 as a whole rotates, so that the locking part 123 may be moved toward the second direction D2. Since the second direction D2 is a direction intersecting the first direction D1, the stopper portion 114 does not hinder the movement. Thereby, the locking part 123 will be disengaged from the stopper 114, so that the sliding door 120 enters the unlocked state. In the unlocked state, the movement of the sliding door 120 in the first direction D1 is no longer restricted. As described above, in the unlocked state, when the live and neutral pins are inserted into the live and

neutral holes

111, 112 and the body portion 121 is pushed, the sliding door 120 slides in the first direction D1, so that the plug 200 is fully inserted into the socket 100.

By providing the lock portion 123 and the unlock portion 124 on the sliding door 120, it is possible to reliably lock the sliding of the sliding door 120 and cancel the slide restriction of the sliding door in a simple rotational manner. Because the locking and unlocking modes of the embodiment of the disclosure are simple and reliable, the reliability of the socket 100 in terms of misplug prevention is increased. In addition, the sliding door 120 does not deform or wear significantly during the process, which is very advantageous for the socket, which is a device requiring frequent operations, and can effectively prolong the service life of the sliding door 120 and the socket 100.

In some embodiments of the present disclosure, the case 100 may include a first blocking portion 119, the first blocking portion 119 being disposed at a distance from the unlocking portion 124, and configured to block the unlocking portion 124 after the unlocking portion 124 moves a distance toward the second direction D2. As an example, the first blocking portion 119 may be a portion of the case 110 protruding toward the unlocking portion 124. When only the ground pin is inserted into the ground hole 113, the ground pin pushes the unlocking part 124 to move in the second direction D2, and drives the locking part 123 to disengage from the limiting part 114. However, since no pins are inserted into the fire wire hole 111 and the neutral wire hole 112, the sliding door 120 and the body portion 121 thereof do not slide in the first direction D1, and the unlocking portion 124 is blocked by the first blocking portion 119 and cannot move further in the second direction D2, thereby blocking the ground pin from being inserted further into the socket 100. In this manner, insertion of a single pin into the receptacle 100 may be prevented in the event that only the single pin is inserted into the ground pole aperture 113.

In certain embodiments of the present disclosure, the socket 100 further includes a spring 130, the spring 130 being coupled to the housing 110 and the sliding door 120, the spring 130 being configured to bias the sliding door 120 in a direction opposite to the first direction D1. Specifically, when the sliding door 120 is not subjected to an external force of the plug 200, for example, when the plug 200 is disengaged from the socket 100, the sliding door 120 may slide toward a direction opposite to the first direction D1 under the bias of the elastic member 130, thereby returning the body portion 121 of the sliding door 120 to a position where the live wire hole 111 and the neutral wire hole 112 are closed, that is, a position of the sliding door 120 shown in fig. 1. As an example, the elastic member 130 may be a coil spring. It is understood that the elastic member 130 may also be a leaf spring or an elastic body made of an elastic material such as rubber. However, coil springs are preferred over other elastomers because they are less prone to failure under repeated use and long load, and have the advantages of low cost and ease of installation and replacement.

In certain embodiments of the present disclosure, the stopper portion 114 is provided with a slope 1141 inclined with respect to the first direction D1. Specifically, after the plug 200 is disengaged from the socket 100, the sliding door 120 will return to the initial position, i.e., the position of the sliding door 120 shown in fig. 1, under the bias of the elastic member 130. In this process, the stopper portion 114 may adversely affect the return of the sliding door 120. By providing the slope 1141, the locking portion 123 of the sliding door 120 can be smoothly returned to the initial position beyond the stopper portion 114.

In certain embodiments of the present disclosure, the elastic member 130 is further configured to bias the sliding door 120 in a direction opposite to the second direction D2. In this way, it is beneficial to bias the locking portion 123 of the sliding door 120 to the position locked by the position-limiting portion 114, and it is also ensured that the sliding door 120 can move back and forth along the route parallel to the first direction D1 after being unlocked, thereby avoiding the sliding door 120 from moving to other positions in the housing 110 and failing to achieve the desired function.

In some embodiments of the present disclosure, the sliding door 120 further includes a strip-shaped hole 127 and a biasing portion 128, the biasing portion 128 is adjacent to the locking portion 123, and the housing 110 is provided with a post 118, the post 118 passes through the strip-shaped hole 127 and extends to below the sliding door 120, and an elastic member 130 is coupled between a portion of the post 118 below the sliding door 120 and the biasing portion 128. Specifically, one end of the elastic member 130 may be mounted to the biasing portion 128 adjacent to the locking portion 123, which helps to bias the locking portion 123. In addition, the post 118 may be formed on an upper portion of the housing 110, such as the cover 110-1 shown in FIG. 5B, which facilitates manufacture of the post 118 and assembly of the receptacle 100. The cylinder 118 also extends to below the sliding door 120, and the other end of the elastic body 130 is fixed to a portion of the cylinder 118 below the sliding door 120, whereby the elastic body 130 can be extended in an obliquely upward direction and biases the biasing portion 128. By this mounting, it is facilitated that the elastic body 130 biases the sliding door 120 in a direction opposite to both the first direction D1 and the second direction D2 to cause the locking portion 123 to approach the stopper portion 114, and during sliding of the sliding door 120, the sliding door 120 and the locking portion 123 thereof are caused to move substantially along a route parallel to the first direction D1. However, it is understood that the elastic body 130 may be installed at other suitable positions as long as the sliding door 120 can be biased in a desired direction.

Fig. 3A to 3D show cross-sectional views of the socket 100 and the plug 200 in various stages of insertion of the three-prong plug 200 into the socket 100.

In fig. 3A, the ground pin of the plug 200 is inserted into the ground hole 113 of the socket 100 and just contacts the unlocking part 124 of the sliding door 120. At this time, the locking part 123 is still located at the position blocked by the stopper part 114, and thus the sliding door 120 is in the locked state. In fig. 3B, the ground pin inserted into the ground hole 113 is further moved downward and pushes the unlocking portion 124 of the sliding door 120 to rotate toward the second direction D2, which disengages the locking portion 123 of the sliding door 120 from the stopper portion 114, whereby the sliding door 120 is in an unlocked state. At the same time, the hot and neutral pins of the plug 200 move downward into contact with the body portion 121. In addition, since the sliding door 120 is already in the unlocked state, the live pin and the neutral pin, which continue to move downward, slide on the first slope 1211 and the second slope 1212 of the body part 121 to push the body part 121 to move toward the first direction D1, thereby pushing the sliding door 120 to slide toward the first direction D1 as a whole. In fig. 3C, as the sliding door 120 slides in the first direction D1, the locking part 123 at the other end of the sliding door 120 goes over the stopper part 114. Further, under the bias of the elastic body 130, the locking part 123 rotates back to a position contacting the housing 110 to continue moving toward the first direction D1. In fig. 3D, the ground, live and neutral pins of the plug 200 will continue to move downwardly and the body portion 121 is moved to a position to fully open the

live holes

111 and 112. The live and neutral pins contact the contact pad 140 and are thereby electrically connected to the live and neutral wires.

As can be seen from fig. 3A to 3D, in the case where the three-pin plug 200 is simultaneously inserted into the respective insertion holes of the socket 100 in a correct manner, the sliding door 120 can be slid open, thereby completing the normal engagement of the plug with the socket. On the other hand, if a two-pin plug is inserted into the live hole 111 and the neutral hole 112 of the outlet 100, the sliding door 120 cannot slide since the locking part 123 is blocked by the stopper 114, thereby preventing the plug from further moving downward. In addition, the insertion of a single pin into any of the receptacles would obviously not allow the sliding door 120 to be moved and not fully inserted into the receptacle 100. For example, when a single pin is inserted into the ground hole 113, the unlocking part 124 of the sliding door 120 is pushed, but since the body part 121 is not moved toward the first direction D1, the sliding door 120 is not opened, and the single pin is also blocked by the unlocking part 124 and the first blocking part 119 from being inserted further downward.

Fig. 4A shows a side cross-sectional view of the socket 100 according to an embodiment of the present disclosure, and fig. 4B shows a side cross-sectional view of the socket 100 into which a plug is inserted.

In some embodiments of the present disclosure, the inner side of the housing 110 is further provided with at least one first protrusion 115 and at least one second protrusion 116, and wherein the body portion 121 is configured to be able to rotate clockwise and abut against the at least one first protrusion 115 under an external force applied by the live prong, or rotate counterclockwise and abut against the at least one second protrusion 116 under an external force applied by the neutral prong, so as to limit the body portion 121 from sliding in the first direction D1.

As an example, as shown in fig. 4A, the sliding door 120 may be rotated or deflected in a plane perpendicular to the sliding direction, in addition to being able to slide in the first direction D1 or the direction opposite to D1. As shown in fig. 4B, when the plug is inserted into both the neutral wire hole 112 and the ground wire hole 113 of the outlet 100, the neutral pin inserted into the neutral wire hole 112 is pressed to the second slope 1212 of the body 121, while the first slope 1211 of the body 121 is not pressed, so that the body 121 is rotated counterclockwise toward one side. Meanwhile, the ground pin inserted into the ground hole 113 rotates the locking part 123 to a position separated from the stopper 114, and the neutral pin pushes the body part 121 toward the first direction D1 since the neutral pin is pressed to the second slope 1212 of the body part 121. In this case, the body portion 121 will abut against the second protrusion 116 (i.e., the protrusions 116-1 and 116-2) and be blocked by the second protrusion 116 from sliding toward the first direction D1. Similarly, when a plug is inserted into both the hot hole 111 and the earth hole 113 of the receptacle 100, the hot pin inserted into the hot hole 112 presses against the first ramp 1211 of the body 121, while the second ramp 1212 of the body 121 is not pressed, so that the body 121 will rotate counterclockwise toward the other side. Meanwhile, the ground pin inserted into the ground hole 113 rotates the locking part 123 to a position separated from the stopper 114, and since the live pin is pressed to the first slope 1211 of the body part 121, the live pin pushes the body part 121 toward the first direction D1. In this case, the body portion 121 will abut against the first protrusion 115 (i.e., the protrusions 115-1 and 115-2) and be blocked by the first protrusion 115 from sliding toward the first direction D1.

By further providing the first protrusion 115 and the second protrusion 116, when two plugs are simultaneously inserted into the ground pole hole 113 and the live wire hole 111, or the ground pole hole 113 and the neutral wire hole 112, even if the unlocking part 124 of the sliding door 120 is pushed to the unlocking position by the ground pole pin, the sliding door 120 cannot be slid to the position of opening the live wire hole 111 and the neutral wire hole 112. That is, when only any two jacks (whether or not ground pole holes 113 are included) are plugged, the sliding door 120 of the socket 100 will not open the live and

neutral holes

111, 112, thereby further improving the safety of the socket 100.

Fig. 5A and 5B illustrate perspective views of the cover 110-1, and fig. 6 illustrates a perspective view of the base 110-2. In some embodiments of the present disclosure, the case 110 includes a cover body 110-1 provided with a wire hole 111, a neutral wire hole 112 and a ground pole hole 113, and a base 110-2 accommodating the conductive contact piece 140, wherein the stopper portion 114 is provided on the cover body 110-1, and the at least one first protrusion 115 includes one first protrusion 115-1 provided on the cover body 110-1 and another first protrusion 115-2 provided on the base 110-2, and the at least one second protrusion 116 includes one second protrusion 116-1 provided on the cover body 110-1 and another second protrusion 116-2 provided on the base 110-2.

Specifically, the cover 110-1 and the base 110-2 may be secured together to form the housing 110, such as by being secured with screws. A cavity is formed between the cover 110-1 and the base 110-2. The sliding door 120 may be disposed in the cavity and slide between the cover 110-1 and the base 110-2 to prevent or allow plug insertion contact with the conductive contacts 140 in the base 110-2. The stopper 114 and the cylinder 118 may be both disposed on the cover 110-1 and protrude toward the base 110-2. Further, a first protrusion 115-1 and a first protrusion 115-2 may be provided on the cover 110-1 and the base 110-2, respectively, and a second protrusion 116-1 and a second protrusion 116-2 may be provided on the cover 110-1 and the base 110-2, respectively.

Fig. 7A shows a perspective view of the body portion 121 and the cover 110-1, and fig. 7B shows a perspective view of the body portion 121 and the base 110-2. As an example, as shown in FIGS. 7A and 7B, with the ground and neutral pins inserted into the ground and neutral holes, the body portion 121 rotates and abuts against the second protrusion 116-1 on the cover 110-1, while the body portion 121 will also abut against the second protrusion 116-2 on the base 110-2. Similarly, when the ground pin and the fire pin are inserted into the ground hole and the fire hole, the body 121 rotates and abuts against the first protrusion 115-1 on the cover 110-1, and the body 121 also abuts against the first protrusion 115-2 on the base 110-2. It is understood that the protrusion may be provided only on the cover 110-1 or the base 110-2, which may also limit the sliding of the sliding door 120. However, in contrast, it is more preferable to provide the protrusions on both the cover 110-1 and the base 110-2, because forming a plurality of protrusions on the cover 110-1 and the base 110-2, respectively, can restrict the sliding of the sliding door 120 at a plurality of positions, further improving the reliability of the socket 100.

In certain embodiments of the present disclosure, the housing 110 includes a slide rail 117, and the body portion 121 includes a slide slot 1213 that mates with the slide rail 117, the slide slot 1213 being disposed in a middle portion of a bottom side of the body portion 121 facing away from the live and

neutral apertures

111, 112. By providing the sliding rail 117 and the sliding groove 1213, the resistance to sliding of the sliding door 120 is advantageously reduced. Further, since the sliding groove 1213 is provided at the bottom side middle portion of the body portion 121, the body portion 120 can rotate around the sliding groove 1213 when pressed by the single pin, i.e., the sliding rail 117 and the sliding groove 1213 can serve as a rotation fulcrum of the sliding door 120. Therefore, the sliding rail 117 and the sliding groove 1213 can contribute to both sliding and rotation of the sliding door 120.

In some embodiments of the present disclosure, the case 110 may further include a second blocking portion 1110 (see fig. 5B), the second blocking portion 1110 being adjacent to the body portion 121 and configured to block the body portion 121 in a direction opposite to the first direction D1. As an example, second blocking portion 1110 may be provided at a position of cover body 110-1 adjacent to fire wire hole 111 and neutral wire hole 112. For example, one rib may be provided near each of the live and

neutral holes

111 and 112. By providing the second blocking portion 1110, the sliding range of the sliding door 120 in the direction opposite to the first direction D1 may be limited, thereby limiting the sliding door 100 within the range under the insertion hole of the receptacle 100.

In the embodiment of the present disclosure, by providing the sliding door with the lock portion and the unlock portion, it is possible to reliably lock the sliding of the sliding door and cancel the slide restriction of the sliding door in a simple rotational manner. The locking and unlocking modes of the disclosed embodiment are simple and reliable, and the sliding door is not easy to deform and damage, so that the service life and the reliability of the socket are improved. Furthermore, certain embodiments of the present disclosure also prevent the insertion of a pin into the socket interior in the event that either two receptacles (whether or not ground holes are included) or either receptacle is inserted with a pin.

Many modifications and other embodiments of the disclosure set forth herein will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the embodiments of the disclosure are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the disclosure. Moreover, although the foregoing description and the related drawings describe example embodiments in the context of certain example combinations of components and/or functions, it should be appreciated that different combinations of components and/or functions may be provided by alternative embodiments without departing from the scope of the present disclosure. In this regard, for example, other combinations of components and/or functions than those explicitly described above are also contemplated within the scope of the present disclosure. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
