Description

Technical Field

[0001] This disclosure pertains to the field of electronic devices, and particularly relates to a socket. Background Technology

[0002] A socket is a common electronic device used to plug in electrical equipment, thereby providing power to the equipment.

[0003] In related technologies, a socket includes a housing, a protective door, and a socket assembly. The housing has a socket opening, and both the protective door and the socket assembly are located within the housing. The protective door is movable between a first position and a second position within the housing. When the protective door is in the first position, it blocks the socket opening, preventing accidental contact with the live socket assembly. When a plug is inserted into the socket, it pushes the protective door to the second position, exposing the socket and allowing the plug to contact the live socket assembly for power. When the plug is removed from the socket, the protective door returns to the first position under the action of a spring, continuing to provide protection against electric shock.

[0004] However, because the safety door is a spring-driven, reset-type mechanical structure, when the spring fails, the safety door will remain in the second position, causing the safety door to lose its function of preventing electric shock. Summary of the Invention

[0005] This disclosure provides a socket that improves its safety. The technical solution is as follows:

[0006] This disclosure provides a socket, including:

[0007] The casing has an insertion hole on one side;

[0008] A protective door is movably located within the housing. When the protective door is in a first position, it blocks the socket; when the protective door is in a second position, the socket is exposed.

[0009] Terminal assembly, connected to the inner wall of the housing;

[0010] The terminal assembly and the socket assembly are respectively connected to the inner wall of the housing;

[0011] The protective door is configured to move from a first position to a second position under the action of an external force, so that the socket assembly contacts the terminal assembly.

[0012] In one implementation of this disclosure, either the terminal assembly or the socket assembly has a spring.

[0013] The spring clip of the terminal assembly is used to contact the socket assembly when driven by the protective door;

[0014] The spring tab of the socket assembly is used to contact the terminal assembly when driven by the protective door.

[0015] In one implementation of this disclosure, the housing includes a fixing frame and a pressure plate;

[0016] One side of the fixing frame has a receiving groove;

[0017] The pressure plate is located at the opening of the receiving groove, and the pressure plate has through holes;

[0018] The protective door is located on one side of the pressure plate, the terminal assembly and the socket assembly are located on the other side of the pressure plate, and a portion of the spring piece passes through the perforation and is opposite to the protective door, or a portion of the protective door passes through the perforation and is opposite to the spring piece.

[0019] In another implementation of this disclosure, there are two perforations, which are arranged at intervals from each other;

[0020] The socket assembly has two parts: a live wire socket assembly and a neutral wire socket assembly. The live wire socket assembly corresponds to one of the through holes, and the neutral wire socket assembly corresponds to the other through hole.

[0021] The terminal assembly has two components: a live wire terminal assembly and a neutral wire terminal assembly. The live wire terminal assembly corresponds to one of the through holes, and the neutral wire terminal assembly corresponds to the other through hole.

[0022] In another implementation of this disclosure, the protective door has pushers on both sides, and the two pushers correspond to the two through holes respectively;

[0023] One of the spring pieces passes through the corresponding perforation and is opposite to one of the pushers, while the other spring piece passes through the corresponding perforation and is opposite to the other pusher.

[0024] In another implementation of this disclosure, when the terminal assembly has the spring tab, the insert assembly abuts against the wall of the through hole;

[0025] When the socket assembly has the spring tab, the terminal assembly abuts against the wall of the through hole.

[0026] In another implementation of this disclosure, the wall of the perforation has a bayonet.

[0027] The bayonet engages with the terminal assembly or the socket assembly.

[0028] In another implementation of this disclosure, the protective door has two pushers on the side facing the pressure plate, and the two pushers correspond to the two through holes respectively;

[0029] One of the pushers passes through the corresponding perforation and is opposite to one of the spring pieces, while the other pusher passes through the corresponding perforation and is opposite to the other spring piece.

[0030] In another implementation of this disclosure, the pusher has an inclined surface that slides in contact with the spring sheet.

[0031] In another implementation of this disclosure, when the protective door is in the first position, the distance between the pusher and the spring piece is 1-3 mm in the direction of movement of the pusher; and / or,

[0032] When the protective door is in the first position, the distance between the spring and the terminal assembly or the socket assembly is not less than 3.2 mm in the direction of movement of the spring.

[0033] The beneficial effects of the technical solutions provided in this disclosure are:

[0034] Under normal conditions, the protective door is not subjected to external forces and is in the first position, effectively blocking the socket. Furthermore, the socket assembly is not in contact with the terminal assembly, meaning the socket assembly is de-energized. In this state, not only does the protective door prevent electric shock by blocking the socket, but also, because the socket assembly is de-energized, even if a finger comes into contact with the socket assembly due to a malfunction of the protective door assembly, no electric shock will occur.

[0035] When powered on, the plug of the electrical device is inserted into the socket, applying external force to the protective door. The protective door then moves from the first position to the second position, exposing the socket and allowing the plug to pass through and be inserted into the socket assembly. During the movement of the protective door from the first position to the second position, the socket assembly contacts the terminal assembly, meaning the socket assembly is energized. In this state, the plug can draw power normally.

[0036] Therefore, the socket provided in this embodiment has a dual protection against electric shock under normal conditions: one is the protective door, and the other is the spacing between the socket assembly and the terminal assembly. In this way, even if the protective door fails and a finger comes into contact with the socket assembly, no electric shock will occur. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0054] A socket is a common electronic device used to plug in electrical equipment, thereby providing power to the equipment.

[0055] In related technologies, a socket includes a housing, a protective door, and a socket assembly. The housing has a socket opening, and both the protective door and the socket assembly are located within the housing. The protective door is movable between a first position and a second position within the housing. When the protective door is in the first position, it blocks the socket opening, preventing accidental contact with the live socket assembly. When a plug is inserted into the socket, it pushes the protective door to the second position, exposing the socket and allowing the plug to contact the live socket assembly for power. When the plug is removed from the socket, the protective door returns to the first position under the action of a spring, continuing to provide protection against electric shock.

[0056] However, because the safety door is a spring-driven, reset-type mechanical structure, when the spring fails, the safety door will remain in the second position, causing the safety door to lose its function of preventing electric shock.

[0057] To address this technical problem, embodiments of this disclosure provide a socket. Figure 1 For an exploded view of this socket, please participate. Figure 1 In this embodiment, the socket includes a housing 10, a protective door 20, a terminal assembly 30, and a socket assembly 40. One side of the housing 10 has a socket 110. The protective door 20 is movably located inside the housing 10. When the protective door 20 is in a first position, the protective door 20 blocks the socket 110. When the protective door 20 is in a second position, the socket 110 is exposed. The terminal assembly 30 and the socket assembly 40 are respectively connected to the inner wall of the housing 10.

[0058] The protective door 20 is configured to move from a first position to a second position under the action of an external force, so that the socket assembly 40 contacts the terminal assembly 30.

[0059] Figure 2 This is a diagram illustrating the state switching of the socket, combined with... Figure 2 Under normal conditions, the protective door 20 is not subjected to external forces and is in the first position, capable of blocking the socket 110. Furthermore, the socket assembly 40 is not in contact with the terminal assembly 30, meaning the socket assembly 40 is de-energized. In this state, not only does the protective door 20 block the socket 110 to prevent electric shock, but also, because the socket assembly 40 is de-energized, even if a finger comes into contact with the socket assembly 40 due to a malfunction of the protective door 20, no electric shock will occur.

[0060] When powered on, the plug of the electrical device is inserted into the socket 110, applying external force to the protective door 20. The protective door 20 then moves from the first position to the second position, exposing the socket 110, allowing the plug to pass through the socket 110 and be inserted into the socket assembly 40. During the movement of the protective door 20 from the first position to the second position, the socket assembly 40 contacts the terminal assembly 30, meaning the socket assembly 40 is energized. In this state, the plug can draw power normally.

[0061] Therefore, the socket provided in this embodiment has a dual protection against electric shock under normal conditions: one is the protective door 20, and the other is the spacing between the socket assembly 40 and the terminal assembly 30. In this way, even if the protective door 20 fails and a finger comes into contact with the socket assembly 40, no electric shock will occur.

[0062] In this embodiment, either the terminal assembly 30 or the socket assembly 40 has a spring 50. The spring 50 of the terminal assembly 30 is used to contact the socket assembly 40 when actuated by the protective door 20. The spring 50 of the socket assembly 40 is used to contact the terminal assembly 30 when actuated by the protective door 20.

[0063] In the above implementation, the spring piece 50 can move under the action of the protective door 20, causing the terminal assembly 30 and the socket assembly 40 to change from being spaced apart to being in contact. After the protective door 20 is no longer in use, the spring piece 50, under its own elastic force, causes the terminal assembly 30 and the socket assembly 40 to change from being in contact to being spaced apart.

[0064] That is, in some examples, the terminal assembly 30 has a spring 50 that moves while the socket assembly 40 remains stationary. In other examples, the socket assembly 40 has a spring 50 that moves while the terminal assembly 30 remains stationary.

[0065] See you again Figure 1 In this embodiment, the housing 10 includes a fixing frame 120 and a pressure plate 130. One side of the fixing frame 120 has a receiving groove 121, the pressure plate 130 is located at the opening of the receiving groove 121, and the pressure plate 130 has a through hole 131.

[0066] The protective door 20 is located on one side of the pressure plate 130, the terminal assembly 30 and the socket assembly 40 are located on the other side of the pressure plate 130, and a portion of the spring piece 50 passes through the through hole 131 opposite to the protective door 20 (see...). Figure 3 Alternatively, a portion of the protective door 20 passes through the perforation 131 opposite the spring clip 50 (see...). Figure 4 ).

[0067] In the above implementation, both the socket assembly 40 and the terminal assembly 30 are located within the receiving groove 121, that is, inside the fixing frame 120, while the protective door 20 is located outside the fixing frame 120. This further improves the safety of the socket.

[0068] There are two ways for the protective door 20 and the spring contact 50 to engage. In the first way, the spring contact 50 passes through one side of the pressure plate 130 to the other side, thus facing the protective door 20. In the second way, the protective door 20 passes through one side of the pressure plate 130 to the other side, thus facing the spring contact 50. Both methods enable the engagement between the protective door 20 and the spring contact 50, allowing the protective door 20 to move from the first position to the second position, thereby facilitating contact between the terminal assembly 30 and the socket assembly 40.

[0069] In this embodiment, there are two through holes 131, which are arranged at intervals. There are two socket assemblies 40: a live wire socket assembly 411 and a neutral wire socket assembly 412. The live wire socket assembly 411 corresponds to one through hole 131, and the neutral wire socket assembly 412 corresponds to the other through hole 131. There are two terminal assemblies 30: a live wire terminal assembly 311 and a neutral wire terminal assembly 312. The live wire terminal assembly 311 corresponds to one through hole 131, and the neutral wire terminal assembly 312 corresponds to the other through hole 131.

[0070] In the above implementation, the live wire socket assembly 411 and the live wire terminal assembly 311 are separate designs, as are the neutral wire socket assembly 412 and the neutral wire terminal assembly 312, which effectively ensures the safety of the socket under normal conditions.

[0071] It should be noted that if the socket is a three-hole socket, then the socket assembly 40 has three parts: in addition to the live wire socket assembly 411 and the neutral wire socket assembly 412, it also has a ground wire socket assembly 413. Correspondingly, the terminal assembly 30 also has three parts: in addition to the live wire terminal assembly 311 and the neutral wire terminal assembly 312, it also has a ground wire terminal assembly 313. Since the ground wire is not energized, the ground wire socket assembly 413 and the ground wire terminal assembly 313 do not need to be designed separately; they can be directly connected.

[0072] The following sections will introduce the two ways in which the protective door 20 and the spring clip 50 are matched.

[0073] For the first type of combination, see [link / reference]. Figure 1 and Figure 3 In this embodiment, the protective door 20 has pushers 210 on both sides, and the two pushers 210 correspond to two through holes 131 respectively. One spring piece 50 passes through the corresponding through hole 131 and is opposite to one pusher 210, and the other spring piece 50 passes through the corresponding through hole 131 and is opposite to the other pusher 210.

[0074] In the above implementation, the two spring contacts 50 correspond to the two pushers 210 respectively. This ensures that the two spring contacts 50 move smoothly until the terminal assembly 30 and the socket assembly 40 contact, thereby energizing the socket assembly 40. Furthermore, since the pushers 210 are located on both sides of the protective door 20, the protective door 20 can be used to separate the two spring contacts 50, avoiding the problem of short circuit.

[0075] For example, the line connecting the two pushers 210 is parallel to the line connecting the two springs 50. This design allows both springs 50 to be driven by the pushers 210 simultaneously, effectively improving the reliability of the movement of the springs 50.

[0076] In some examples, the pusher 210 and the protective door 20 are integrated structural components, which not only improves structural strength but also increases manufacturing efficiency.

[0077] In this embodiment, when the terminal assembly 30 has a spring tab 50, the socket assembly 40 abuts against the wall of the through hole 131. When the socket assembly 40 has a spring tab 50, the terminal assembly 30 abuts against the wall of the through hole 131.

[0078] In the above implementation, when the terminal assembly 30 has the spring piece 50, that is, when the socket assembly 40 remains stationary, the socket assembly 40 abuts against the wall of the through hole 131, and the wall of the through hole 131 provides stable support for it, thereby facilitating the stable abutment of the spring piece 50. Similarly, when the socket assembly 40 has the spring piece 50, that is, when the terminal assembly 30 remains stationary, the terminal assembly 30 abuts against the wall of the through hole 131, and the wall of the through hole 131 provides stable support for it, thereby facilitating the stable abutment of the spring piece 50.

[0079] For example, the wall of the perforation 131 has a snap-fit ​​132 that engages with the terminal assembly 30 or the socket assembly 40.

[0080] In the above implementation, the bayonet 132 can be used to fix the terminal assembly 30 or the socket assembly 40, thus preventing the terminal assembly 30 or the socket assembly 40 from shaking.

[0081] In some examples, the spring 50 has silver contacts, which effectively improves conductivity during electrical contact.

[0082] The second method of combination, Figure 5 For an exploded view of the socket, see [link / reference]. Figure 5 and Figure 4In this embodiment, the protective door 20 has two pushers 210 on the side facing the pressure plate 130, and the two pushers 210 correspond to two through holes 131 respectively. One pusher 210 passes through the corresponding through hole 131 and is opposite to a spring piece 50, and the other pusher 210 passes through the corresponding through hole 131 and is opposite to another spring piece 50.

[0083] In the above implementation, the two spring pieces 50 correspond to the two pushers 210 respectively. This ensures that the two spring pieces 50 move smoothly until the socket assembly 40 and the terminal assembly 30 contact, thereby energizing the socket assembly 40. Furthermore, since the pusher 210 passes through the through hole 131 and is located within the receiving groove 121, it ensures that the two spring pieces 50 are completely located within the receiving groove 121, thus further improving electrical safety.

[0084] For example, the line connecting the two pushers 210 is parallel to the line connecting the two springs 50. This design allows both springs 50 to be driven by the pushers 210 simultaneously, effectively improving the reliability of the movement of the springs 50.

[0085] In some examples, the pusher 210 and the protective door 20 are integrated structural components, which not only improves structural strength but also increases manufacturing efficiency.

[0086] In some examples, the pusher 210 has a ramp 211 that slides in contact with the spring 50.

[0087] In the above implementation, the inclined plane 211 is used to change the moving direction of the spring 50, so that the spring 50 can contact the terminal assembly 30 or the socket assembly 40 more accurately.

[0088] In this embodiment, when the protective door 20 is in the first position, the distance between the pusher 210 and the spring piece 50 is 1 to 3 mm in the moving direction of the pusher 210.

[0089] In other words, under normal conditions, the protective door 20 is in the first position, at which point the pusher 210 and the spring 50 are spaced apart and do not directly contact each other. This ensures that the spring 50 will only move after the pusher 210 has moved 1-3mm. This prevents small objects from being inserted into the socket 110, which could cause the pusher 210 to move only a small distance and then activate the spring 50, further improving the electrical safety of the socket.

[0090] In some examples, when the protective door 20 is in the first position, the distance between the pusher 210 and the spring 50 is 2 mm in the direction of movement of the pusher 210.

[0091] In this embodiment, when the protective door 20 is in the first position, the distance between the spring 50 and the terminal assembly 30 or the socket assembly 40 in the moving direction of the spring 50 is not less than 3.2mm.

[0092] Under normal conditions, the distance between the spring 50 and the terminal assembly 30 or the socket assembly 40 is at least 3.2 mm. This distance ensures that the spring 50 will not contact the terminal assembly 30 or the socket assembly 40, thus preventing the socket assembly 40 from being accidentally energized. Of course, the distance between the spring 50 and the socket assembly 40 should not be too large, to avoid the spring 50 needing too much travel to contact the socket assembly 40, and also to avoid insufficient contact between the spring 50 and the socket assembly 40.

[0093] As mentioned above, the core principle behind the two mating methods between the protective door 20 and the spring 50 is the same: the protective door 20 directly drives the spring 50, allowing it to contact the socket assembly 40. This guides the current from the terminal assembly 30 to the socket assembly 40, enabling the plug inserted into the socket assembly 40 to draw power. Because the protective door 20 directly drives the spring 50, the spring 50 can directly receive the force applied by the protective door 20, simplifying the structure and ensuring a stable contact between the spring 50 and the terminal assembly 30 or the socket assembly 40.

[0094] The previous sections introduced two ways of cooperating between the protective door 20 and the spring 50. The following section introduces the protective door 20.

[0095] See Figure 1 In this embodiment, the housing 10 also includes a face cover 140, which is connected to the fixing frame 120 to seal the pressure plate 130 in the groove of the receiving groove 121, and the protective door 20 is sandwiched between the face cover 140 and the pressure plate 130.

[0096] In the above implementation, the protective door 20 is sandwiched between the faceplate 140 and the pressure plate 130, ensuring that the protective door 20 can move stably under the action of external force.

[0097] In this embodiment, an elastic element 220 is sandwiched between the protective door 20 and the cover 140, and the extension and retraction direction of the elastic element 220 is consistent with the movement direction of the protective door 20.

[0098] When the protective door 20 moves from the first position to the second position under the action of an external force, the elastic element 220 is compressed and accumulates elastic potential energy. When the external force is removed, the elastic potential energy of the elastic element 220 is released, driving the protective door 20 to reset from the second position to the first position and remain in the first position.

[0099] In this embodiment, the housing 10 also includes a panel 150, which is connected to the fixing frame 120 and covers the face cover 140.

[0100] It is easy to understand that, in order to ensure that the plug can pass through the socket 110 and be inserted into the socket assembly 40, the panel 150, the cover 140, and the pressure plate 130 all have sockets 110 arranged in opposite directions.
