Abstract

A protective cover for a socket, comprising: a base 300; an LN-pole cover 200 for the live and neutral poles, with protrusions 210a, 210b which extend into L-pole hole and N-pole holes of the socket; and, an E-pole cover 100 for the earth pole, pivotally mounted to the base, with a protrusion 110 which extends into an E-pole hole. The covers interact and the E-pole cover pivots relative to the base when an E-pole pin is inserted, such that the protrusion 110 leaves the E-pole hole. A socket is formed with: the protective cover; a face cover 20, which has the LN-pole and E-pole holes; and a bottom casing 30, which provides the conductive terminals. The E-pole cover may engage the LN-pole cover, so the protrusions leave their holes. The E-pole cover may be mounted via a shaft-bore fitting. An anti-rotation device may prevent the LN-pole cover from rotating.

Description

PROTECTIVE COVER ASSEMBLY FORA SOCKET
AND A SOCKET
FIELD
100011 Embodiments of the present disclosure generally relate to sockets, and more particularly to protective cover assemblies for sockets.
BACKGROUND
100021 Some sockets are provided with a protective cover which covers a socket hole of the socket. When the plug is not inserted into the socket, the protective cover covers the socket hole of the socket to prevent dust or decoration contaminants from entering the interior of the socket; when the plug is inserted into the socket, the protective cover gets open to allow the pins to be inserted into the socket to establish an electrical connection. However, a conventional socket protective cover is not satisfactory. This is mainly reflected in the following aspects. Although the protective cover is disposed, there is still a deep pit at the socket hole, and the terminals in the socket may still be seen at some socket holes (such as the E electrode). Small objects may enter the socket through the deep pit, and may cause a hidden safety hazard. In addition, dust or decoration contaminants may easily enter the deep pit, which is difficult to clean and may even block the socket hole, affecting the normal use of the socket.
100031 So far, there is no solution that may well overcome the above drawbacks of the socket. Therefore, it is desirable to improve the protective cover of a conventional socket.
SUMMARY
100041 One of the objects of the present utility model is to provide a protective cover assembly for a socket and a socket to solve or eliminate one or more of the above technical problems.
100051 According to a first aspect of the present disclosure, a protective cover assembly for a socket is provided. The protective cover assembly comprises: a base; an LN-pole protective cover mounted on the base and comprising a second protrusion and a third protrusion adapted to respectively extend into an L-pole hole and an N-pole hole of the socket; and an E-pole protective cover pivotally mounted to the base and including a first protrusion adapted to extend into an E-pole hole of the socket, the E-pole protective cover being configured to interact with the LN-pole protective cover and capable of pivoting relative to the base in response to insertion of an E-pole pin of a plug mated with the socket such that the first protrusion leaves the E-pole hole.
[0006] In some embodiments, the E-pole protective cover may engage with the LN-pole protective cover such that the E-pole protective cover presses the LN-pole protective cover during pivoting, thereby driving the second protrusion and the third protrusion to leave the L-pole hole and N-pole hole of the socket.

[0015] In some embodiments, the protective cover assembly further comprises an anti-rotation device configured to prevent the LN-pole protective cover from rotating relative to the base when the E-pole protective cover pivots.
[0016] In some embodiments, the anti-rotation device comprises: a further shaft disposed on one of the LN-pole protective cover and the base and extending toward the other of the LN-pole protective cover and the base; and a further bore disposed in the other of the LN-pole protective cover and the base and configured to receive the further shaft.
[0017] In some embodiments, the protective cover assembly further comprises: a first return spring disposed obliquely and compressively between the E-pole protective cover and the base, and adapted to apply a force to the E-pole protective cover, thereby enabling the first protrusion of the E-pole protective cover to protrude into the E-pole hole of the socket.
[0018] In some embodiments, the protective cover assembly further comprises: a second return spring configured to apply a force to the LN-pole protective cover such that when the LN-pole protective cover is at a predetermined position, the second protrusion and the third protrusion of the LN-pole protective cover can respectively extend into the L-pole hole and N-pole hole of the socket.
[0019] In some embodiments, the second return spring is disposed adjacent to an engagement portion between the E-pole protective cover and the LN-pole protective cover.
[0020] In some embodiments, the protective cover assembly further comprises a third return spring configured to be compressed by the base such that the protective cover assembly is driven to translate as a whole in a direction perpendicular to the insertion direction of the pins when the pins of the three-pin plug are drawn out of the socket.
[0021] According to a second aspect of the present disclosure, there is provided a socket. The socket comprises: a face cover provided with an E-pole hole, an L-pole-hole and an N-pole hole for receiving pins of a three-pin plug; the protective cover assembly as stated in the above aspect; and a bottom casing including conductive terminals forming conductive connection with the pins of the plug.
[0022] In some embodiments, the first protrusion, the second protrusion and the third are protrusion substantially flush with the E-pole hole, the L-pole hole and the N-pole hole.
[0023] In some embodiments, the bottom casing comprises a limiting portion for limiting a reset position of the protective cover assembly [0024] According to the protective cover assembly of the embodiment of the present disclosure, the protrusions of the protective cover assembly can protrude into the E-pole hole, L-pole hole and N-pole hole of the socket, and the appearance surface of the protective cover assembly flushes with the appearance surface of the socket panel, which can prevent dust and decoration contaminants from entering the socket holes and improve the safety and aesthetics of the socket.

DETAILED DESCRIPTION OF EMBODIMENTS
[0034] The principles of the present disclosure will now be described with reference to various exemplary embodiments illustrated in the figures. It should be appreciated that the description of the embodiments is only to enable those skilled in the art to better understand and further implement the present disclosure, and is not intended to limit the scope of the disclosure in any way. It should be noted that similar or identical reference numerals may be used in the figures, where possible, and similar or identical reference numerals may indicate similar or identical functions. Those skilled in the art will readily appreciate that alternative embodiments of the structures and methods described herein may be employed without departing from the principles of the present utility model described herein.
[0035] Structural details of a protective cover assembly for a socket according to an exemplary embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that, for convenience of description, directions such as "up", "down", "left", "right", "horizontal" and "vertical" are only exemplarily illustrated by taking examples shown in the figures as examples, and positional relationship and the movement directions between various components may be adaptively adjusted according to actual application.
[0036] As shown in FIGS. 1 and 2, schematic views of a socket 1 according to an exemplary embodiment of the present disclosure are shown. As may be seen in FIG 1, the protective cover is flat in appearance with respect to the socket cover, and the protective cover substantially flushes with the appearance surface. In this type of socket, the socket hole is completely blocked by the protective cover, thereby improving the safety of the socket and effectively preventing the entry of dust and decoration contaminants. In addition, the aesthetics of the socket are also significantly improved.
[0037] Although the protective cover is flat in appearance relative to the socket cover in the illustrated embodiment, the protective cover may not flush with the socket cover in some embodiments. For example, the socket hole may be provided with a guiding feature. In some embodiments (not shown), the protrusions of the protective cover extends partially into the socket hole, and the inner surface of the socket hole may form a guiding feature. In addition, it should be appreciated that although the present disclosure has been described by taking a three-hole socket in a two-hole-three-hole combination panel socket as an example, the inventive concept of the present disclosure may also apply to a separate three-hole socket and various sockets integrating the three-hole socket.
[0038] A schematic diagram of the main components of the socket 1 is shown in the exploded view of FIG 2. As shown, the socket 1 includes a face cover 20, a protective cover assembly 10, and a bottom casing 30. The face cover 20 includes a hole face and a face frame surrounding the hole face. The face cover 20 may be mounted to the bottom casing 30. The protective cover assembly 10 is disposed between the face cover 20 and the bottom case 30.
The bottom casing 30 includes a conductive terminal 40 that forms an electrically conductive connection with the pins of the plug. Since the components such as the face cover 20, the bottom casing 30, the conductive terminal 40, and the like are well known in the art, a detailed description thereof will be omitted, and the structure of the protective cover assembly 10 related to the present disclosure will be mainly described.
[0039] The structural details of the protective cover assembly 10 of the embodiment of the present disclosure are described in detail below with reference to FIG. 3-FIG. 6. FIG. 3 shows an overall schematic view of the protective cover assembly 10 of an embodiment of the present disclosure, and FIGS. 3-6 illustrate structural schematic diagrams of an E-pole protective cover 100, an LN-pole protective cover 200, and a base 300 of the protective cover assembly 10 of the embodiment of the present disclosure, respectively.
[0040] As shown in FIG 3, the protective cover assembly 10 may include an E-pole protective cover 100, an LN-pole protective cover 200, and a base 300. The E-pole protective cover 100 and the LN-pole protective cover 200 are mounted on the base 300.
[0041] The E-pole protective cover 100 is pivotally mounted to the base 300 and includes a first protrusion 110 that may extend into the E-pole hole of the socket. When the E-pole pin of the plug is inserted into the E-pole hole, that is, when the E-pole pin presses the first protrusion 110 of the E-pole protective cover 100, the E-pole protective cover 100 is pivoted as a whole with respect to the base 300, so that the first protrusion 110 leaves the E-pole hole.
[0042] The LN-pole protective cover 200 includes a second protrusion 210a and a third protrusion 210b that may protrude into the L-pole hole and the N-pole hole of the socket, respectively. The LN-pole protective cover 200 is configured to interact with the E-pole protective cover 100. When the E-pole protective cover 100 is pivoted as a whole with respect to the base 300, with the pivotal movement of the E-pole protective cover 100, the LN-pole protective cover 200 is driven to move downward. Details regarding the movement of the E-pole protective cover 100 and the LN-pole protective cover 200 will be further described below in connection with FIGS. 7-10.
[0043] In some embodiments, the E-pole protective cover 100 and the LN-pole protective cover 200 can engage with each other such that the E-pole protective cover 100 presses the LN-pole protective cover 200 during pivoting, thereby driving the second protrusion 210a and the third protrusion 210b to leave the L-pole hole and the N-pole hole of the socket.
[0044] In the illustrated embodiment, with particular reference to FIGS. 4 and 5, the E-pole protective cover 100 includes a projection 120, and the LN-pole protective cover 200 includes a recess 220 adapted to engage the projection. When the first protrusion 110 of the E-pole protective cover 100 is pressed down by the E-pole pin of the plug, the projection can engage with the recess. By such an engagement structure, when the E-pole protective cover 100 is pivotally moved, the LN-pole protective cover 200 will be pressed downward, thereby bringing the LN-pole protective cover 200 to move downward. It should be appreciated that this is only exemplary, and the projection 120 and the recess 220 may reversely configured. For example, the LN-pole protective cover 200 includes the projection 120, whereas the E-pole protective cover 100 is provided with the recess 220, which may also achieve the above-mentioned interaction purpose. Furthermore, the shape of the projection and the recess is not limited as long as the interaction can be formed through engagement of the two. In addition, the engagement structure of the projection and recess is also merely exemplary, and such a structure is simple to manufacture and can meet the movement requirement. It should be understood that other interaction arrangements may also be used. As an example, the E-pole protective cover 100 may include a shaft extending in a horizontal direction, the shaft may be inserted into a bore provided in the LN-pole protective cover 200, and the above-described interaction purpose may also be achieved.
[0045] In some embodiments, as shown in FIGS. 3 and 4, the E-pole protective cover 100 is pivotally mounted to the base 300 by the engagement of the shaft and the hole. The E-pole protective cover 100 includes a shaft portion 130 that extends parallel to the first protrusion 110 and that is adapted to be pivotally mounted to a bore 330 in the sidewall.
[0046] In some embodiments, the base 300 is provided with a bore adapted to receive a shaft portion. As shown in FIG. 6, the base 300 includes sidewalls 310 opposite to each other, the sidewalls each having a notch 320 formed thereon to move way for the pivotal path of the first protrusion 110. With such a structure, the structure is simple and simultaneously can ensure that the pivotal movement of the E-pole protective cover 100 is not interfered.
[0047] In some embodiments, the base 300 may include a barrier portion configured to abut against the E-pole protective cover 100 when the E-pole protective cover 100 is pivoted to a predetermined position to cause the protective cover assembly 10 to translate as a whole in a direction perpendicular an insertion direction of the pins. With the aid of the barrier portion, the force pressing down the E-pole protective cover 100 may be converted into a force that causes the cover assembly 10 to translate in the horizontal direction. In some embodiments, the barrier portion is disposed at a bottom surface of the cutout 320. With such a structure, the position of the barrier portion is easy to control and the barrier portion is easy to form. In some embodiments, the barrier portion may be disposed at a pivotal joint of the E-pole protective cover 100 and the base 300. The barrier portion may be formed into various shapes.
In some embodiments, the barrier portion 260 is formed in a stepped shape, and the E-pole protective cover 100 is provided with a corresponding step portion 360 that mates with the barrier portion. By means of the step shape, it may be ensured that the E-pole protective cover 100 and the base 300 are in surface contact when they are translated to ensure a smoother overall movement of the protective cover assembly. Details regarding the structure of the barrier portion and the movement of the E-pole protective cover 100 and the base 300 will be further described below with reference to FIGS. 7-10.
[0048] The engagement structure between the LN-pole protective cover 200 and the base 300 will be further described below. In some embodiments, as shown in FIGS. 5 and 6, the LN-pole protective cover 200 may be provided with a shaft 340 extending toward the other of the LN-pole protective cover 200 and the base 300, the other of the LN-pole protective cover 200 and the base the 300 is provided with a bore 240 for receiving the shaft 340, and the LN-pole protective cover 200 and the base 300 are mounted together via the shaft-bore fitting.
100491 One of the LN-pole protective cover 200 and the base 300 is provided with a shaft 340 extending toward the other of the LN-pole protective cover 200 and the base 300, and the other of the LN-pole protective cover 200 and the base 300 is provided with a bore 240 for receiving the shaft 340, and the LN-pole protective cover 200 and the base 300 are mounted together via the shaft-bore fitting. It should be understood that use of the mounting manner via the shaft-bore fitting is merely exemplary, and other structures may be employed as long as it may be ensured that the LN-pole protective cover 200 may move up and down relative to the base 300 and the LN-pole protective cover 200 can move horizontally with the base 300 as a whole when the LN-pole protective cover 200 is pressed. In the embodiment not shown, the base 300 may be formed with a groove in an up-down direction, and the LN-pole protective cover 200 may form a slider that engages with the groove in the up-down direction.
100501 In some embodiments, the protective cover assembly 10 may further include an anti-rotation device for preventing the LN-pole protective cover 200 from rotating relative to the base 300 when the E-pole protective cover 100 is pivoted. In the illustrated embodiment, the LN-pole protective cover 200 is provided with the further shaft 250 that extends toward the base 300. The base 300 is provided with the further bore 350 for receiving the further shaft 250. The shaft-bore structure constitutes the anti-rotation device. With two shaft-bore engagement structures, it is possible to prevent the LN-pole protective cover 200 from moving in the horizontal direction with respect to the base 300. It should be understood that such a structure is merely exemplary and other configurations may be employed. For example, the previously-described groove-slider structure may also be used as the anti-rotation device.
100511 In some embodiments, the protective cover assembly 10 includes a plurality of return springs for resetting the E-pole protective cover 100, the LN-pole protective cover 200, and the protective cover assembly 10, respectively.
100521 In the illustrated embodiment, the first return spring 400 is disposed obliquely and compressively between the E-pole protective cover 100 and the base 300, and is adapted to apply a force to the E-pole protective cover 100, thereby enabling the first protrusion 110 of the E-pole protective cover 100 to extend into the E-pole hole of the socket. When the first protrusion 110 of the E-pole protective cover 100 is pressed by the E-pole pin of the plug, the first protrusion 110 pivots against the force of the first return spring 400. When the E-pole pin of the plug is drawn out of the E-pole hole of the socket, the first return spring 400 applies a force to the E-pole protective cover 100 to reset the E-pole protective cover 100. In some embodiments, the E-pole protective cover 100 and the base 300 are provided with a hooked portion to ensure that the position of the spring is relatively stable.
[0053] In the illustrated embodiment, the second return spring 500 is configured to apply a force to the LN-pole protective cover 200 such that when the LN-pole protective cover 200 is at a predetermined position, the second protrusion 210a and third protrusion 210b of the LN-pole protective cover 200 can extend into the L-pole hole and N-pole hole of the socket, respectively. When the first protrusion 110 of the E-pole protective cover 100 pivots to drive the LN-pole protective cover 200 to move downward, the LN-pole protective cover 200 needs to be pressed against the force of the second return spring 500; when the E-pole protective cover 100 resets, the second return spring 500 applies an force to the LN-pole protective cover 200 to drive the LN-pole protective cover 200 to move upward to reset. In some embodiments, the second return spring 500 may be disposed between the EN-pole protective cover 200 and the base 300. In some embodiments, the second return spring 500 may be disposed between the LN-pole protective cover 200 and the bottom casing 30 of the socket.
There is no special requirement for the arrangement position of the second return spring 500 as long as the second return spring 500 may apply a force to the LN-pole protective cover 200 to reset the LN-pole protective cover 200. In some embodiments, the second return spring 500 is placed around the shaft between the LN-pole protective cover 200 and the base 300 to ensure that the position of the spring is relatively stable.
100541 In some embodiments, the second return spring 500 is disposed adjacent to an engagement portion between the E-pole protective cover 100 and the LN-pole protective cover 200. Such an arrangement may make even distribution of the acting force between the E-pole protective cover 100 and the LN-pole protective cover 200 more balanced.
[0055] In the illustrated embodiment, a third return spring 600 is configured to be compressed by the base 300 such that the protective cover assembly 10 is driven to translate as a whole in a direction perpendicular to the insertion direction of the pins when the pins of the three-pin plug are drawn out of the socket. In some embodiments, the third return spring 600 is horizontally disposed between the base 300 of the protective cover assembly 10 and the bottom casing 30 of the socket. In some embodiments, the base 300 and the bottom casing 30 are provided with an abutment portion or hooked portion of the spring to ensure that the position of the spring is relatively stable. When the first protrusion 110 of the E-pole protective cover 100 is pressed to the predetermined position by the E-pole pin of the plug, a downward acting force of the plug provides a force component for the horizontal movement of the E-pole protective cover 100, and under action of the horizontal force component, the protective cover assembly 10 as a whole moves horizontally against the acting force of the third return spring 600; when the E-pole pin of the plug is drawn out of the E-pole hole of the socket, the third return spring 600 applies a horizontal force to the protective cover assembly 10 to push the protective cover assembly 10 to move in an opposite direction to reset. In some embodiments, the bottom casing 30 of the socket includes a limiting portion for limiting the position of movement of the protective cover assembly. It can be used to limit the position of movement of the protective cover assembly 10 in an opposite direction.
[0056] In the illustrated embodiment, the first, second and third return springs 400, 500, 600 are each implemented in the form of a helical spring. It should be understood that this is merely exemplary and that the return spring may employ other springs such as coil spring and leaf spring.
[0057] An operation process of the protective cover assembly according to an exemplary embodiment of the present disclosure will be described below with reference to FIGS. 7-10. For the sake of clarity, some of the reference numerals have been omitted from the figures and some components have been removed.
[0058] FIG 7 is a schematic view showing a state in which pins are not inserted into the socket. In this state, the protective cover assembly 10 is at an initial position. As shown in FIG 7, particularly referring to (a), (b) and (c), at this time, the first protrusion 110 of the E-pole protective cover 100 and the second protrusion 210a and the third protrusion210b of the LN-pole protective cover 200 substantially flush with the socket holes of the socket. The E-pole pin 2 of the socket contacts the first protrusion 110, that is, presses the first protrusion 110. At the initial position, the first return spring 400 applies an oblique upward force to the E-pole protective cover 100 such that the first protrusion of the E-pole protective cover 100 remains inserted in the E-pole hole of the socket; the second return spring 500 applies a vertical upward force to the second and third protrusions 210a, 210b of the LN-pole protective cover 200 such that the second and third protrusions 210a, 210b of the LN-pole protective cover 200 remain extended into the L-pole hole and N-pole hole of the socket.
100591 FIG. 8 shows a schematic view showing a state in which the E-pole pin 2 has started to be inserted into the E-pole hole but the LN-pole pins have not yet contacted the corresponding protrusions. In this state, when the E-pole pin 2 has started to be inserted into the E-pole hole, the E-pole pin 2 presses the first protrusion 110 of the E-pole protective cover 100, and the first protrusion 110 moves downward. Since the E-pole protective cover 100 is pivotally coupled with respect to the base 300, the E-pole protective cover 100 pivots about the shaft 130 against the action of the first return spring 400. The E-pole protective cover 100 performs a rotary motion, and the surface of the E-pole protective cover 100 provided with the first protrusion 110 is inclined. When the E-pole protective cover 100 is pivoted to a predetermined position, the projection 120 of the E-pole protective cover 100 engages the recess 220 of the cover 200 of the LN-pole protective cover 200. Therefore, as the E-pole protective cover 100 pivots, the LN-pole protective cover 200 begins to move downward against the action force of the second return spring 500. In this state, as shown, particularly (c), the first protrusion, the second protrusion and the third protrusion are still located on the traveling path of the pins of the plug.
100601 FIG. 9 shows a schematic diagram showing a state in which the E-pole pin, L-pole pin and N-pole pin of the plug are further inserted into the E-pole hole. Since the E-pole protective cover 100 performs a rotational motion, the surface of the E-pole protective cover 100 provided with the first protrusion 110 will be inclined. The downward acting force from the pins of the plug will provide a horizontal force component via the inclined surface. At this position, the stepped portion 260 of the E-pole protective cover 100 is in surface contact with the stepped portion 360 of the base 300, ensuring that the E-pole protective cover 100 does not continue to rotate any more, and may ensure reliable transmission of the horizontal force component. By virtue of the action of the horizontal force component, the protective cover assembly 100 is pushed to move horizontally to the right direction against the action of the third return spring 600. As shown, in particular, in particular (c) and (d), the first protrusion, the second protrusion and the third protrusion will be offset from the initial position, thereby allowing the E-pole, L-pole, and N-pole poles to continue to be inserted.
100611 Fig. 10 shows a schematic view showing a state in which the plug is further inserted from the state of Fig. 9. As shown, in particular, as shown in (a), the E-pole pin 2 of the plug begins to contact the E-pole terminal after going by the protective cover assembly. Similarly, the L-pole pin and N-pole pin continue to be inserted and go by the protective cover assembly to begin contacting the L-pole and N-pole terminals. From this state, the plug continues to be inserted and the plug will be completely inserted into the socket.
[0062] The protective cover assembly according to an embodiment of the present disclosure is capable of providing effective protection to the socket hole without causing any hindrance to the movement of the pins of the plug.
