Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of electrical connectors, and in particular to safety sockets. [Background technology]
[0002] Electric shock damage can occur during everyday electrical use, particularly when water gets into a socket. Sockets are found in every corner of our work and living spaces, and accidentally spilling water into a socket can flood the socket's charging port, potentially increasing the risk of electric shock during use. Current safety standards require that the charging port of a socket be hidden inside the socket case when no plug is inserted, preventing direct contact with the outside world. However, sockets that do not meet current safety standards allow water to enter the socket through the socket port when water is spilled into the socket or accidentally submerged in water. Inserting a plug into a water-filled socket can result in electric shock. While using a water-filled socket does not necessarily result in electric shock, it is an undeniable fact that a water-filled socket poses a higher risk of electric shock than a dry socket. Therefore, conventional technology requires further improvement. Summary of the Invention [Problem to be solved by the invention]

[0037] Electric shock damage can occur during everyday electrical use, particularly when water gets into a socket. Sockets are found in every corner of our work and living spaces, and accidentally spilling water into a socket can flood the socket's charging port, potentially increasing the risk of electric shock during use. Current safety standards require that the charging port of a socket be hidden inside the socket case when no plug is inserted, preventing direct contact with the outside world. However, sockets that do not meet current safety standards allow water to enter the socket through the socket port when water is spilled into the socket or accidentally submerged in water. Inserting a plug into a water-filled socket can result in electric shock. While using a water-filled socket does not necessarily result in electric shock, it is an undeniable fact that a water-filled socket poses a higher risk of electric shock than a dry socket. Therefore, conventional technology requires further improvement.
[0038] In order to solve the above problem, the present patent provides a safety socket, which aims to solve the problem that water can enter the socket hole when the socket is not in use.
[0039] For ease of understanding, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0040] Referring to FIG. 1, the safety socket includes a surface case unit 100 including a first case 110 having a socket hole 111 for inserting a plug pin, a bottom case 200 provided below the first case 110, a protective door 300 provided between the first case 110 and the bottom case 200 and abutting against the inner surface of the first case 110 and closing the socket hole 111 when a plug pin is not inserted into the socket, a driving member 410 provided on the protective door 300 and / or the first case 110 for driving the protective door 300 so as to be attached to the first case 110, and a driving guide 420 provided on the surface case unit 100 and including a guide portion for guiding the movement direction of the protective door 300 when a plug pin is inserted into or removed from the socket hole 111.
[0041] In this embodiment, the first case 110 of the front case unit 100 can block most of the water from leaving the first case 110. The protective door 300 is provided between the first case 110 and the bottom case 200 to block water from entering the socket hole 111. When a plug pin is not inserted into the socket, the protective door 300 abuts against the inner surface of the first case 110 and blocks the socket hole 111, thereby effectively blocking water from entering the socket hole 111. The protective door 300 can abut against the inner surface of the first case 110 in various ways, such as entirely or partially, as long as it meets the requirement of blocking the socket hole 111.
[0042] The driving member 410 of the driving guide structure 400 drives the protective door 300 to stick to the first case 110, so that when the plug pin is not inserted, the protective door 300 sticks to the first case 110 and can block the socket hole 111, or when the plug pin is pulled out, the protective door 300 can be reset to a position that blocks the socket hole 111 when the plug pin is not inserted.
[0043] The guide portion 420 of the drive guide structure 400 can guide the movement direction of the protective door 300 when the plug pin is inserted into or removed from the socket hole 111, thereby guiding the protective door 300 to move in a direction that allows the plug pin to be inserted when the plug pin is inserted into the socket hole 111, or guiding the protective door 300 to move in a direction that blocks the socket hole 111 when the plug pin is removed.
[0044] This solves the problem of water being able to enter the socket hole 111 when the socket is not in use.
[0045] The plug pin is inserted through the socket hole 111 of the first case 110, and the terminals and other structures of the socket are located inside the bottom case 200, so that the plug pin can penetrate the protective door 300 to electrically connect the plug pin to the safety socket. The specific implementation form that meets the above needs is not limited in this embodiment, and for ease of understanding, the present application provides a preferred implementation form.
[0046] 6 and 7, the protective door 300 is provided with a through hole 310 for the plug pin to pass through. The through hole 310 is misaligned with the socket hole 111 when the plug pin is not inserted into the socket so that the protective door 300 covers the socket hole 111.
[0047] In this embodiment, the protective door 300 is provided with a through-hole 310 for the plug pin to pass through so that the plug pin can be electrically connected to the safety socket. When the plug pin is not inserted into the socket, the through-hole 310 is misaligned with the socket hole 111, thereby realizing the effect of the protective door 300 blocking the socket hole 111.
[0048] In addition, based on the above technical solution in which the driving member 410 of the driving guide structure 400 drives the protective door 300 so that it is attached to the first case 110, there is a technical problem of how the driving member 410 drives the protective door 300 so that it is attached to the first case 110. In order to solve the above problem, the following solution is further provided.
[0049] Referring to Figure 1, the driving member 410 includes a first magnet 411 provided on the protective door 300 and a second magnet 412 provided on the surface case unit 100, and the first magnet 411 and the second magnet 412 are attracted to or repel each other, thereby attaching the protective door 300 to the first case 110.
[0050] In this embodiment, the protective door 300 and the surface case unit 100 are provided with a first magnet 411 and a second magnet 412, and by utilizing the mutual attraction or repulsion effect of the first magnet 411 and the second magnet 412, the protective door 300 is attached to the first case 110, thereby achieving the technical effect of driving the driving member 410 to attach the protective door 300 to the first case 110.
[0051] The protective door 300 is attached to the first case 110 by the first magnetic body and the second magnet 412. In order to achieve the effect of attaching the protective door 300 to the first case 110 by the mutual attraction or repulsion of the first magnet 411 and the second magnet 412, it is necessary to determine the positions of the first magnet 411 and the second magnet 412. Specific embodiments that meet the above needs are not limited in this embodiment, and for ease of understanding, the present application provides preferred embodiments.
[0052] Optionally, the surface case unit 100 further includes a second case, the protective door 300 is arranged between the first case 110 and the second case, the second magnet 412 is arranged in the second case and repels the first magnet 411, and the first magnet 411 is positioned between the second magnet 412 and the socket hole 111 in the horizontal direction.
[0053] In this embodiment, the second magnet 412 is provided on the second case, and the first magnet 411 is provided horizontally between the second magnet 412 and the socket hole 111, so that the protective door 300 can be attached to the first case 110 and block the socket hole 111 under the mutual repulsive action of the first magnet 411 and the second magnet 412.
[0054] In addition, based on the above technical solution that the first magnet 411 and the second magnet 412 repel each other, there is a technical solution for how to make the first magnet 411 and the second magnet 412 attract each other to achieve the above needs, and the following solution is further provided to solve the above problem.
[0055] 1-3, the second magnet 412 is provided in the first case 110 and is attracted to the first magnet 411.
[0056] In this embodiment, a first magnet 411 is provided on the protective door 300, and a second magnet 412 is provided on the first case 110, and the first magnet 411 and the second magnet 412 attract each other, so that the protective door 300 can be attached to the first case 110 and block the socket hole 111.
[0057] In addition, based on the above technical solution of using the first magnet 411 and the second magnet 412 to drive the protective door 300 so that it is attached to the first case 110, there is a technical problem of how to fix the first magnet 411 and the second magnet 412. In order to solve the above problem, the following solution is further provided.
[0058] 2-3 and 6-7, the protective door 300 is provided with a first accommodating groove for fixing the first magnet 411, and the surface case unit 100 is provided with a second accommodating groove for fixing the second magnet 412.
[0059] In this embodiment, a first storage groove for fixing the first magnet 411 is provided in the protective door 300, and a second storage groove for fixing the second magnet 412 is provided in the surface case unit 100, so that the first magnet 411 and the second magnet 412 can fix the protective door 300 and the surface case unit 100, respectively.
[0060] Note that the first magnet 411 is fixed to the first receiving groove of the protection door 300, and the second magnet 412 is fixed to the second receiving groove of the protection door 300, and since the attractive or repulsive force between the first magnet 411 and the second magnet 412 is not large, the distance between the first magnet 411 fixed to the first receiving groove and the second magnet 412 fixed to the second receiving groove needs to be close. Specific embodiments that meet the above needs are not limited in this embodiment, and for ease of understanding, the present application provides preferred embodiments.
[0061] Optionally, the thickness of the bottom of the first receiving groove is between 0.03 mm and 2 mm.
[0062] In this embodiment, the thickness of the bottom of the first accommodating groove is between 0.03 mm and 2 mm, and the distance between the first magnet 411 fixed to the first accommodating groove and the second magnet 412 fixed to the second accommodating groove is shortened, so that the attractive or repulsive force between the first magnet 411 and the second magnet 412 can drive the protective door 300 to attach to the first case 110 and close the socket hole 111.
[0063] In addition, based on the above technical solution in which the first magnet 411 and the second magnet 412 drive the protective door 300, there are technical issues regarding how to install the first magnet 411 and the second magnet 412 and how to drive the protective door 300. In order to solve the above issues, the following solution is further provided.
[0064] 1-3 and 6-7, the protective door 300 is provided with a first magnet groove 320 in which a first magnet 411 is provided, and the first case 110 is provided with a second magnet groove 330 in which a second magnet 412 is provided, and the first magnet groove 320 and the second magnet groove 330 are aligned with each other when the protective door 300 covers the socket hole 111, and the first magnet 411 and the second magnet 412 are attracted to each other.
[0065] In this embodiment, the protective door 300 and the first case 110 are provided with a first magnet groove 320 and a second magnet groove 330, and the first magnet 411 and the second magnet 412 are respectively provided in the first magnet groove 320 and the second magnet groove 330. When the protective door 300 blocks the socket hole 111, the first magnet groove 320 and the second magnet groove 330 are aligned with each other. As a result, the protective door 300 can be attached to the first case 110 and block the socket hole 111 under the mutual attraction of the first magnet 411 and the second magnet 412.
[0066] In addition, based on the above technical solution in which the first magnet 411 and the second magnet 412 attract each other to drive the protective door 300, there is a technical problem of how to make the first magnet 411 and the second magnet 412 repel each other to drive the protective door 300. In order to solve the above problem, the following solution is further provided.
[0067] 9, the protective door 300 is provided with a first magnet groove 320 in which a first magnet 411 is installed. The front case unit 100 includes a second case with the first case 110 installed above. The second case is provided with a third magnet groove 350 in which a second magnet 412 is installed. When the plug pin is inserted into the socket, the first magnet groove 320 is located between the third magnet groove 350 and the socket hole 111, and the first magnet 411 and the second magnet 412 repel each other.
[0068] In this embodiment, the second case is provided with a third magnet groove 350, and the first and second magnets 411 and 412 are respectively provided in the first and third magnet grooves 320 and 350. When the plug pin is inserted into the socket, the first magnet groove 320 is positioned between the third magnet groove 350 and the socket hole 111. Therefore, when the plug pin is removed, the protective door 300 can be reset to a position that blocks the socket hole 111 and sticks to the first case 110 under the mutual repulsion of the first magnet 411 and the second magnet 412.
[0069] The protective door 300 is attached to the first case 110 and blocks the socket hole 111 by the first magnet 411 and the second magnet 412 fixed in the first magnet groove 320, and the first magnet groove 320 can be implemented in various ways. In an implementation that meets the above requirements, the first magnet 411 fixed in the first magnet groove 320 must enable the protective door 300 to be stably attached to the first case 110 and block the socket hole 111. The specific implementation that meets the above needs is not limited in this embodiment, and for ease of understanding, the present application provides preferred implementations.
[0070] Referring to FIG. 7, the first magnet grooves 320 are provided on both ends of the protection door 300 .
[0071] In this embodiment, first magnet grooves 320 are provided at both ends of the protective door 300, and first magnets 411 are provided in both of the first magnet grooves 320 at both ends, so that the driving action of the first magnets 411 and the second magnets 412 can be uniformly applied to the protective door 300, thereby allowing the protective door 300 to be stably attached to the first case 110 and block the socket hole 111.
[0072] In addition, based on the above technical solution in which the first magnet 411 and the second magnet 412 fixed in the first magnet groove 320 drive the protective door 300, there is a technical problem of how to attach the second magnet 412.

The first case 110 is provided with a magnet mounting boss in which the second magnet 412 is mounted, and the magnet mounting boss is close to the first magnet groove 320.
[0074] In this embodiment, the magnet mounting boss is located close to the first magnet groove 320, and the second magnet 412 is mounted on the magnet mounting boss, so that the driving action of the first magnet 411 and the second magnet 412 can act on the protective door 300. For example, the first magnet 411 and the second magnet 412 are attracted to each other, so that when the plug pin is pulled out, the protective door 300 can be reset to a position that blocks the socket hole 111.
[0075] In addition to the technical solution of using the driving member 410 as a magnet, there are various other implementation forms of the driving member 410.
