Description

Technical Field

[0001] Embodiments of this disclosure relate to sockets, and more particularly to sockets with protective covers. Background Technology

[0002] A socket is a common electrical connection device that connects electrical / electronic devices to a power source or signal source / receiver by inserting the plug of the electrical / electronic device into its socket. The sockets on ordinary sockets are exposed, which poses a potential danger because users may accidentally insert foreign objects into the unobstructed sockets, leading to electric shock, short circuits, or other accidents. Exposed sockets also easily accumulate dust or foreign objects, causing blockages or poor conductive contact. Currently, there are sockets with protective shutters. These sockets have protective shutters in the sockets to close them when the socket is not in use, thus avoiding the aforementioned dangers. However, the traditional protective shutter structure requires multiple parts, resulting in a large number of parts and complex assembly. Furthermore, the complex protective shutter structure is prone to malfunction after repeated use.

[0003] Therefore, it is desirable to provide a socket that not only provides a protective door structure, but also has the advantages of reducing the number of parts and simplifying the socket assembly process. Summary of the Invention

[0004] Traditional sockets suffer from problems such as numerous parts in the safety shutters, complex assembly, and high cost. Embodiments of this disclosure provide an improved socket to solve, or at least partially solve, the aforementioned or other potential problems.

[0005] In a first aspect of this disclosure, a socket is provided. The socket includes: a housing including a panel having a first socket, a second socket, and a third socket disposed thereon, the first socket extending along a first direction, the second socket being spaced apart from and extending parallel to the first socket along the first direction, the third socket extending along a second direction perpendicular to the first direction, and communicating with the second socket; a first protective door slidably disposed in the panel to close or unclose the first and second sockets; and a second protective door slidably disposed in the panel to close or unclose the third socket, wherein one of the first and second protective doors includes a protrusion, and the other includes a groove for receiving the protrusion; wherein the protrusion and the groove are configured to allow relative translation between the first and second protective doors.

[0006] According to embodiments of this disclosure, the first, second, and third sockets of the socket are sealed by first and second protective doors, providing safety protection for the socket. Furthermore, the first and second protective doors can move independently relative to each other via the protrusions and slots. Moreover, the safety protection requirements of the socket are achieved using only the first and second protective doors, which reduces the number of parts and simplifies the assembly complexity of the socket.

[0007] In some embodiments, the socket further includes a first elastic member arranged along a first direction, with its two ends abutting against a second protective door and a panel, respectively. The second protective door is capable of translation along the first direction. Because the second protective door is capable of translation along the first direction, it can translate as short a distance as possible to release the closure of the third socket. This helps to reduce the size of the second protective door to obtain a compact and low-cost socket structure.

[0008] In some embodiments, the socket further includes a second elastic member arranged along a second direction, with its two ends abutting against the first protective door and the panel, respectively. The first protective door is translatable along the second direction. Because the first protective door is translatable along the second direction, it can translate as short a distance as possible to release the closure of the first and second sockets. This helps to reduce the size of the first protective door to obtain a compact and low-cost socket structure.

[0009] In some embodiments, the second protective door further includes an upper wall and a lower wall spaced apart by a slot. This results in a second protective door with a simple structure and low cost.

[0010] In some embodiments, the first protective door includes a body having a first side facing the first socket and a second side facing away from the first socket.

[0011] In some embodiments, the protrusion extends from the body onto a second side near the body. Thus, the protrusion does not affect the first protective door's ability to close the first and second sockets.

[0012] In some embodiments, the body further includes a boss protruding from the second surface in a direction opposite to the first surface; the housing also includes a base coupled to the panel, the base including a stop and a support surface for supporting the boss; wherein when only a single object is inserted into one of the first, second, and third sockets, the first and second protective doors jointly deflect relative to the base with the boss as a fulcrum, and then abut against the stop. Thus, when only a single object is inserted into one of the sockets, the first and second protective doors can deflect and abut against the stop, preventing the protective doors from translating or further deflecting. In this way, the socket remains closed by the first and second protective doors, further improving the protective performance of the protective doors for the socket.

[0013] In some embodiments, the stop includes: a first portion disposed in the base, which restricts the movement of a first protective door to keep the first protective door closed when only a single object is inserted into the first socket; a second portion disposed in the panel, which restricts the movement of the first protective door to keep the first protective door closed when only a single object is inserted into the second socket; and a third portion disposed in the base, which restricts the movement of the second protective door to keep the second protective door closed when only a single object is inserted into the third socket. Thus, when only a single object is inserted into a socket, the first, second, and third portions can reliably restrict the translation and deflection of the first and second protective doors, ensuring that the socket is reliably closed by the first and second protective doors.

[0014] In some embodiments, the panel further includes a guide wall disposed along a first direction, the guide wall being configured to guide the translation of the second protective door. This results in smoother translation of the second protective door, providing a highly stable protective door structure.

[0015] In some embodiments, the first protective door includes a first bevel and a second bevel adapted to respectively close the first and second sockets. In such embodiments, the bevels can be pressed by a plug inserted into the socket, thereby enabling the translation of the first protective door.

[0016] In some embodiments, the second protective door includes a third bevel adapted to close the third socket. In such embodiments, the bevel can be pressed by a plug inserted into the socket, thereby enabling the second protective door to translate.

[0017] In some embodiments, the socket also includes a grounding socket disposed on the panel.

[0018] It should be understood that this content is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of the invention. Other features of the invention will become readily apparent from the following description. Attached Figure Description

[0030] The present disclosure will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the technical solutions disclosed herein.

[0031] As used herein, the term "comprising" and its variations shall be interpreted as an open-ended term meaning "including but not limited to". The term "based on" shall be interpreted as "based on at least a portion". The terms "one embodiment" and "embodiment" shall be understood as "at least one embodiment". The term "another embodiment" shall be understood as "at least one other embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may be included below. Unless the context clearly indicates otherwise, the definitions of terms are consistent throughout the specification.

[0032] A socket housing typically consists of a panel and a base that can be assembled together. The panel has two-prong, three-prong, or both. The base contains conductive plates, and the pins of an electrical / electronic device's plug, after being inserted into the socket, make electrical connections with the corresponding conductive plates, thus connecting the electrical / electronic device to a power source or signal source / receiver, etc.

[0033] A protective shutter can be installed in the socket to close the socket on the panel, and when a pin is inserted, the closure of the socket is released to allow the pin to enter the socket.

[0034] Figure 1 An exploded view of a socket 1 according to an embodiment of the present disclosure is shown. Figure 1 As shown, the housing of the socket 1 includes a panel 10. The panel 10 is provided with a first socket 12, a second socket 131, and a third socket 132. In some embodiments, the panel 10 is also provided with a grounding socket 11.

[0035] The first socket 12 and the second socket 131 extend parallel to each other along a first direction Y, and the second socket 131 is spaced apart from the first socket 12. The third socket 132 extends along a second direction X perpendicular to the first direction Y, and the third socket 132 communicates with the second socket 131.

[0036] The first socket 12 and the second socket 131 (and optional ground socket 11) together are adapted to one type of plug, and the first socket 12 and the third socket 132 (and optional ground socket 11) together are adapted to another type of plug.

[0037] In some embodiments, the socket 1 further includes a base 20 that can be coupled to the panel 10, and the base 20 and the panel 10 are provided with a stop portion (for example, the stop portion includes a first portion 22 in the base 20, a second portion 15 in the panel 10, and a third portion 24 in the base 20, which will be described in detail below).

[0038] like Figure 1 As shown, the socket 1 also includes a first protective door 40 disposed in the panel 10. The first protective door 40 is translatable between a closed position and an open position. In the closed position, the first protective door 40 closes the first socket 12 and the second socket 131, and in the open position, the first protective door 40 releases the closure of the first socket 12 and the second socket 131.

[0039] One of the first protective door 40 and the second protective door 30 includes a protrusion 41, and the other includes a groove 35 for receiving the protrusion 41. The protrusion 41 and the groove 35 are configured to allow relative translation between the first protective door 40 and the second protective door 30.

[0040] In some embodiments, the first protective door 40 further includes a protrusion 41. Referring to an exemplary structure of the first protective door 40... Figures 2 to 4 The first protective door 40 may also include a body 400. The body 400 may have various annular shapes, such as a rectangular ring, a circular ring, or a polygonal ring. The body 400 may have a first surface 401 facing the first socket 12 and the second socket 131 and a second surface 402 facing away from the first surface 401.

[0041] In some embodiments, reference Figures 2 to 4 The protrusion 41 extends out of the body 400 from the second surface 402 near the body 400. In this way, the protrusion 41 does not affect the first protective door 40 from sealing the first socket 12 and the second socket 131.

[0042] like Figure 2 As shown, in some embodiments, the body 400 may also be provided with a mounting portion 43 for mounting an elastic element. The mounting portion 43 may be a cylindrical protrusion extending from the inner ring surface of the annular body 400 toward the center of the annulus.

[0043] In some embodiments, reference Figure 2 The body 400 also includes a boss 44 projecting from the second surface 402 in a direction opposite to the first surface 401. In some embodiments, the boss 44 is located in the middle of the body 400, for example, the boss 44 includes two collinear boss portions in the middle of the body 400.

[0044] The boss 44 is used to abut against the support surface 23 on the base 20. Thus, in situations of unsafe use (e.g., when only a single object is inserted into the socket), the boss 44 can serve as a deflection fulcrum for the first protective door 40 (described in detail below).

[0045] In some embodiments, reference Figure 3 The first protective door 40 may include a first inclined surface 460 and a second inclined surface 46 for respectively closing the first socket 12 and the second socket 131. The first inclined surface 460 and the second inclined surface 46 can be pressed by a plug inserted into the socket, and the horizontal component of the applied pressing force can drive the first protective door 40 to translate.

[0046] return Figure 1 The socket 1 also includes a second protective door 30. The second protective door 30 is slidably disposed in the panel 10 to close the third socket 132 in its closed position and to release the third socket 132 in its open position. In some embodiments, the second protective door 30 further includes a groove 35 for receiving a protrusion 41. The protrusion 41 and the groove 35 allow relative translation between the first protective door 40 and the second protective door 30; therefore, the first protective door 40 and the second protective door 30 are decoupled from each other in the translational direction during their respective translational movements.

[0047] Through the protrusion 41 and the groove 35, the first protective door 40 and the second protective door 30 can translate relative to each other, allowing them to move independently relative to each other. Furthermore, the safety protection requirements of the socket 1 are achieved solely through the first protective door 40 and the second protective door 30, which reduces the number of parts in the socket 1 and simplifies its assembly complexity.

[0048] Regarding the exemplary structure of the second protective door 30, refer to Figures 5 to 7 In some embodiments, the second protective door 30 further includes an upper wall 33 and a lower wall 34 spaced apart by a slot 35, the upper wall 33 and the lower wall 34 being connected to each other by a lateral wall 36. Figure 6 As shown, in some embodiments, the second protective door 30 includes a third surface 301 facing the third socket 132.

[0049] In some embodiments, such as Figure 6 As shown, the second protective door 30 may include a protrusion 32 at one end for mounting an elastic element, the protrusion 32 being, for example, cylindrical.

[0050] In some embodiments, such as Figure 6 and Figure 7 As shown, the second protective door 30 includes a third inclined surface 31 adapted to close the third socket 132. The third inclined surface 31 can be pressed by a plug inserted into the socket, and the horizontal component of the applied pressing force can drive the second protective door 30 to translate.

[0051] It should be understood that in the foregoing exemplary embodiments, the protrusion is disposed on the first protective door, and the groove is disposed on the second protective door. In other embodiments, the protrusion may be disposed on the second protective door, and the groove may be disposed on the first protective door.

[0052] Refer again Figure 1 In some embodiments, the socket 1 may further include a first elastic member 39 arranged along a first direction Y. The two ends of the first elastic member 39 abut against the second protective door 30 and the panel 10, respectively, and the first elastic member 39 provides a force that closes the third socket 132 with the second protective door. For example, one end of the first elastic member 39 abuts against the panel 10, and the other end is coupled to a protrusion 32 of the second protective door 30.

[0053] When the correct plug is used, the plug pins are inserted into the third socket 132 and the second protective door 30 is pressed. The component of the plug's pressing force along the first direction Y overcomes the force of the first elastic member 39, causing the second protective door 30 to release the seal on the third socket 132. The second protective door 30 can then translate along the first direction Y.

[0054] In some embodiments, the socket 1 further includes a second elastic member 49 arranged along a second direction X, with its two ends abutting against the first protective door 40 and the panel 10, respectively. The second elastic member 49 provides a force that causes the first protective door 40 to close the first socket 12 and the second socket 131. For example, one end of the second elastic member 49 abuts against the panel 10, and the other end is coupled to the mounting portion 43 of the first protective door 40.

[0055] When the correct plug is used, the plug pins are inserted into the socket 1, and the plug presses down on the first protective door 40. The component of the plug's pressing force along the second direction X overcomes the force of the second elastic member 49, causing the first protective door 40 to release the seal on the first socket 12 and the second socket 131. The first protective door 40 can then be moved along the second direction X.

[0056] In some embodiments, the first elastic element 39 and the second elastic element 49 may be helical springs. In other embodiments, the first elastic element 39 and the second elastic element 49 may also be of other types, and the scope of this disclosure is not strictly limited in this respect.

[0057] Figure 8 A rear view of a socket according to an embodiment of the present disclosure is shown, illustrating the positional relationship between the first and second protective doors when a first type of plug is inserted, with the base 20 omitted. When the plug pins 2 and 3 are simultaneously inserted into the first socket 12 and the third socket 132, pin 2 presses against the first protective door 40, and the component of the pressing force along the second direction X (the component force is in...) Figure 8 The force of the second elastic element 49 is overcome by the force of the first protective door 40 in the positive X direction, thereby allowing the first protective door 40 to move in the positive X direction and release the seal of the first socket 12 and the second socket 131.

[0058] At the same time, the plug pin 3 presses against the second protective door 30 and the force of the pressing force along the first direction Y (the force component is in) Figure 8 The force of the first elastic element 39 is overcome by the force of the second protective door 30 along the positive Y direction, thereby allowing the second protective door 30 to move along the positive Y direction and release the seal of the third insertion hole 132.

[0059] exist Figure 8 As can be seen, the protrusion 41 and the groove 35 allow for relative translation between the first protective door 40 and the second protective door 30.

[0060] In some embodiments, such as Figure 8 As shown, panel 10 may also include guide wall 14 disposed along the first direction Y, guide wall 14 for guiding the translation of the second protective door 30.

[0061] Figure 9A rear view of a socket according to an embodiment of the present disclosure is shown, illustrating the positional relationship between the first and second protective doors when a second type of plug is inserted, with the base 20 omitted.

[0062] As shown in the figure Figure 9 As shown, when the two pins 2 of the plug are simultaneously inserted into the first socket 12 and the second socket 131, the two pins 2 simultaneously press the first protective door 40 and the component of the pressing force along the second direction X (the component force is in...) Figure 9 The force of the second elastic element 49 is overcome by the force of the first protective door 40 in the positive X direction, thereby allowing the first protective door 40 to move in the positive X direction and release the seal of the first socket 12 and the second socket 131.

[0063] The protrusion 41 and the groove 35 allow for relative translation between the first protective door 40 and the second protective door 30. Meanwhile, as... Figure 9 As shown, since no pin is inserted into the third socket 132, the second protective door 30 does not move.

[0064] In a safe operating state, one type of plug pins will be simultaneously inserted into the first socket 12, the second socket 131, and the optional ground socket 11. Since both pins act simultaneously on the first protective door 40, with reference to the boss 44, both sides of the first protective door 40 are subjected to force; that is, the first protective door 40 will not deflect around the boss 44 as a fulcrum. Furthermore, the component of the plug pressing force will cause the first protective door 40 to translate.

[0065] In a safe operating state, another type of plug pin will be simultaneously inserted into the first socket 12, the third socket 132, and the optional ground socket 11. In this case, one pin abuts against the first protective door 40, and the other pin abuts against the second protective door 30. Since the slot 35 accommodates the protrusion 41, the force acting on the second protective door 30 in the Z direction (thickness direction of the socket 1) also acts on the first protective door 40. That is, with reference to the boss 44, the force acts on both sides of the integral structure formed by the first protective door 40 and the second protective door 30, meaning that the integral structure will not deflect with the boss 44 as a fulcrum. Furthermore, the component of the plug pressing force will cause translation of both the first protective door 40 and the second protective door 30.

[0066] In unsafe use situations, the socket 1 provided in this disclosure can prevent the object from being inserted into the socket 1 or coming into contact with the conductive sheet, because the first protective door 40 and the second protective door 30 deflect together when deflection occurs.

[0067] For example, when only one slender object is inserted into any one of the first socket 12, the second socket 131, or the third socket 132, the first protective door 40 and the second protective door 30 together deflect relative to the base 20 with the boss 44 as the fulcrum, and thus abut against the stop, preventing further movement. In this way, it can prevent objects from being inserted into the socket 1 or from contacting the conductive sheet.

[0068] Figures 10 to 11 A schematic diagram is shown when only a single elongated object 200 is inserted into the second socket 131. (See diagram below.) Figures 10 to 11 As shown, only a single object 200 presses the first protective door 40 through the second socket 131; no pin or object presses the first protective door 40 through the first socket 12. Therefore, with the boss 44 as a reference, the first protective door 40 is only subjected to force on one side, which will cause the first protective door 40 to deflect about the boss 44 as a fulcrum, as... Figures 10 to 11 As shown.

[0069] Since the groove 35 accommodates the protrusion 41, the second protective door 30 deflects together with the first protective door 40.

[0070] After the second protective door 30 deflects from the first protective door 40 by a predetermined angle, the second portion 15 of the stop portion provided within the panel 10 restricts the movement of the first protective door 40, for example, by locking the first protective door 40 to prevent translation and further deflection. Thus, the first protective door 40 remains closed to the second socket 131 (and the first socket 12), and the second protective door 30 remains closed to the third socket 132. According to embodiments of this disclosure, a single object 200 cannot be inserted into the socket 1 or contact the conductive sheet.

[0071] In some embodiments, a fourth portion 21 of a stop portion may be provided in the base 20. The fourth portion 21, together with the second portion 15, restricts further deflection of the first protective door 40 and the second protective door 30. For example, the fourth portion 21 restricts deflection by blocking the second protective door 30.

[0072] Figures 12 to 13 This diagram illustrates the situation when only a single object 200 is inserted into the first socket 12. The single object 200 is inserted into the first socket 12 and presses down on the first protective door 40, but no object presses down on the first protective door 40 / second protective door 30 via the second socket 131 / third socket 132. Therefore, with reference to the boss 44, the first protective door 40 is only subjected to force on one side, which will cause the first protective door 40 to deflect about the boss 44 as a fulcrum, as shown below. Figures 12 to 13 As shown.

[0073] Since the groove 35 accommodates the protrusion 41, the second protective door 30 deflects together with the first protective door 40.

[0074] After the second protective door 30 deflects from the first protective door 40 by a predetermined angle, the first portion 22 of the stop portion of the base 20 restricts the deflection of the first protective door 40 and the second protective door 30. For example, the first portion 22 restricts the deflection of the first protective door 40 by blocking it. At this time, the first protective door 40 remains closed to the first socket 12 (and the second socket 131) and the second protective door 30 remains closed to the third socket 132. According to the embodiments of this disclosure, a single object 200 cannot be inserted into the socket 1 or come into contact with the conductive sheet.

[0075] In some embodiments, such as Figures 12 to 13 As shown, the first portion 22 is formed as a stepped wall, comprising a first part 221 with a lower height in the Z direction and a second part 222 with a higher height in the Z direction. The surface of the first part 221 is used to limit further deflection and movement of the first protective door 40 and the second protective door 30, and the second part 222 is used to lock one end of the first protective door 40 after deflection to prevent the first protective door 40 from translating after deflection. This can further improve the safety performance of the socket 1.

[0076] Figures 14 to 15 A schematic diagram is shown with only a single object 200 inserted into the third socket 132. The single object 200 presses against the second protective door 30 via the third socket 132, but no pin or object presses against the first protective door 40 via the first socket 12. Since the slot 35 accommodates the protrusion 41, the second protective door 30 and the first protective door 40 can be viewed as a single structure. In the illustrated case, with reference to the boss 44, this single structure is only subjected to force on one side (i.e., the side with the second protective door 30), which will cause the single structure to deflect about the boss 44 as a fulcrum.

[0077] After the second protective door 30 deflects from the first protective door 40 by a predetermined angle, the second portion 15 of the stop portion provided in the panel 10 will restrict the movement of the first protective door 40, for example, by locking the first protective door 40 to prevent the first protective door from translating and continuing to deflect. At the same time, the third portion 24 of the stop portion provided in the base 20 will restrict the movement of the second protective door 30, for example, by locking the second protective door 30 to prevent the second protective door 30 from translating.

[0078] Thus, the first protective door 40 remains closed to the first socket 12 and the second socket 131, and the second protective door 30 remains closed to the third socket 132. According to embodiments of this disclosure, a single object 200 cannot be inserted into the socket 1 or come into contact with the conductive sheet.

[0079] In some embodiments, the fourth portion 21, together with the second portion 15, can limit further deflection of the first protective door 40 and the second protective door 30, for example, by blocking the second protective door 30 to limit the deflection.

[0080] It should be understood that the detailed embodiments described above are merely illustrative or explanatory of the principles of this disclosure and are not intended to limit the invention. Therefore, any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this invention. Furthermore, the appended claims are intended to cover all variations and modifications to the scope and boundaries of equivalent substitutions falling within the scope and boundaries of the claims.
