A type of socket

Abstract

This utility model describes a socket, comprising: a housing with a through hole extending to the outside; a floating member with a socket for an external plug to be inserted, the floating member having a retracted state and a used state; a first elastic member with its two ends respectively abutting against the inner wall of the housing and the floating member; and a locking assembly with an elastic restoring force. The locking assembly is used to lock the floating member in the retracted state. Under the push of the external plug, the floating member protrudes from the housing, and the locking assembly locks the floating member in the used state. Accordingly, the floating member can be retracted inside the housing, making the socket relatively thin and light. When in use, the user only needs to insert the plug directly, and the thickness of the socket increases accordingly to allow the external plug to be fully inserted into the socket, while avoiding the safety hazard of the plug being exposed. Furthermore, the locking assembly locks the floating member in the used state, thereby preventing the floating member from retracting into the housing during use.

Description

Technical Field

The socket's thickness increases accordingly to allow the external plug to be fully inserted, while preventing the plug from being exposed and posing a safety hazard. Furthermore, the locking assembly locks the floating component in its operating state, preventing it from retracting back into the housing during use. This ensures the floating component is stable and reliable during use, preventing loosening and improving the user experience while reducing potential safety risks. Attached Figure Description

[0040] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0042] Reference Figures 1 to 4This application provides a socket comprising a housing 1, a floating member 2, a first elastic member 3, and a locking assembly 4. The housing 1 has a through hole 121 extending to the outside; the floating member 2 is at least partially located inside the housing 1, and has a socket 22 for an external pin 61 to be inserted into. The floating member 2 has a retracted state and a used state; the two ends of the first elastic member 3 abut against the inner wall of the housing 1 and the floating member 2, respectively; the locking assembly 4 is located inside the housing 1 and has an elastic restoring force; wherein, under its own elastic restoring force, the locking assembly 4 locks the floating member 2 in the retracted state, and the floating member 2 is entirely located inside the housing 1; under the push of the external pin 61, the floating member 2 switches from the retracted state to the used state, and the floating member 2 is pushed out of the through hole 121 by the elastic restoring force of the first elastic member 3, protruding from the housing 1, and the locking assembly 4 locks the floating member 2 in the used state.

[0043] According to the above structure, the socket in this application, through the setting of the locking component 4, allows the floating member 2 to be stored inside the housing 1, that is, the floating member 2 is in a stored state, making the socket relatively thin and light, saving space and making it easy to carry. When using the socket, the user only needs to insert the pin 61 directly, and the floating member 2 will automatically release from the stored state and protrude from the housing 1. The thickness of the socket increases accordingly to allow the external pin 61 to be fully inserted into the socket, while avoiding the safety hazard caused by the exposed pin 61. In addition, the locking component 4 locks the floating member 2 in the use state, thereby preventing the floating member 2 from retracting into the housing 1 during use, ensuring that the floating member 2 is stable and reliable during use and will not loosen, thereby improving the user experience and reducing potential safety risks.

[0044] In some examples, the socket can be as thin as 17mm when folded up, making it lightweight and compact, which greatly improves ease of use and space utilization.

[0045] Reference Figures 4 to 7 In some embodiments, the locking assembly 4 includes: a transmission member 41; at least one locking member 42, which is movably connected to the transmission member 41; a second elastic member 43, the two ends of which abut against the inner wall of the housing 1 and the transmission member 41, respectively; under the elastic restoring force of the second elastic member 43, the transmission member 41 drives the locking member 42 to move closer to the transmission member 41, and the locking member 42 is used for detachable connection with the floating member 2; an external pin 61 abuts against the side of the transmission member 41 away from the second elastic member 43, and drives the locking member 42 away from the transmission member 41, thus releasing the detachable connection between the locking member 42 and the floating member 2, and the locking member 42 abuts against the side of the floating member 2 facing the interior of the housing 1. Specifically, the locking member 42 can be engaged with the floating member 2.

[0046] In the storage state, refer to Figure 8 and Figure 10The elastic restoring force of the second elastic element 43 will push the transmission element 41 against the inner wall of the housing 1. (Refer to...) Figure 5 At this time, the locking element 42 moves closer to the transmission element 41, as shown in the reference. Figure 8 and Figure 11 Furthermore, the locking component 42 is engaged with the floating component 2.

[0047] During the transition from storage mode to usage mode, refer to Figures 13 to 15 When the external pin 61 abuts against the side of the transmission member 41 away from the second elastic member 43, the transmission member 41 will compress the second elastic member 43, and the transmission member 41 will gradually drive the locking member 42 to move.

[0048] In use, refer to Figure 6 The locking element 42 is located away from the transmission element 41. (Refer to...) Figure 13 and Figure 16 At this time, the locking member 42 is released from the engagement with the floating member 2, and the elastic restoring force of the first elastic member 3 pushes the floating member 2 through hole 121 out, the floating member 2 protrudes out of the housing 1, and the locking member 42 abuts against the side of the floating member 2 facing the inside of the housing 1, so as to prevent the floating member 2 from retracting into the housing 1 in the use state and causing an electrical hazard.

[0049] After use, the external pin 61 is pulled out. At this time, the elastic restoring force of the second elastic element 43 will push the transmission element 41 back against the inner wall of the housing 1, and the locking element 42 will once again close to the transmission element 41. (Refer to...) Figure 3 At this point, the floating part 2 still protrudes from the housing 1. The user needs to manually push the floating part 2 back into the housing 1 so that the locking part 42 engages with the floating part 2. At this point, the floating part 2 returns to its retracted state.

[0050] It should be noted that in this application, the description of the locking member 42 being close to or away from the transmission member 41 is a relative positional description. The locking member 42 being away from the transmission member 41 does not mean that it is completely disengaged from the transmission member 41.

[0051] Reference Figure 4 In some embodiments, the housing 1 includes an outer shell 12 and an inner shell 11, with the inner shell 11 connected inside the outer shell 12; the locking assembly 4 is installed in the inner shell 11, and the floating member 2 is located on the side of the locking assembly 4 opposite to the inner shell 11. Specifically, the two ends of the second elastic member 43 can respectively abut against the inner wall of the inner shell 11 and the transmission member 41, and the connecting copper plate 5 of the socket is installed between the inner shell 11 and the outer shell 12.

[0052] Reference Figures 5 to 7 and reference Figures 16 to 17In some embodiments, the transmission member 41 has a sliding post 411 on the side facing the through hole 121; the locking member 42 has a sliding groove 421, and the sliding post 411 is located in the sliding groove 421; under the elastic restoring force of the second elastic member 43 or the push of the external pin 61, the sliding post 411 slides relative to the sliding groove 421, and drives the locking member 42 to move closer to the transmission member 41 or away from the transmission member 41. Thus, the transmission between the locking member 42 and the transmission member 41 is achieved through the cooperation of the sliding post 411 and the sliding groove 421. The transmission structure is simple, reducing potential failure points, and also makes the internal structure of the socket more concise and compact, further reducing the thickness of the socket and making it thinner and lighter overall.

[0053] In some embodiments, under the elastic restoring force of the second elastic member 43 or the push of the external pin 61, the transmission member 41 moves in the first direction; the extending direction of the sliding groove 421 is inclined relative to the first direction. Thus, the movement direction of the locking member 42 is offset from the extending direction of the sliding groove 421. In some examples, the extending direction of the sliding groove 421 forms a 45-degree angle with the first direction.

[0054] Reference Figure 7 In some embodiments, the locking member 42 moves in a second direction, which is perpendicular to the first direction. The housing 1 contains two limiting portions 13, which are spaced apart and symmetrically arranged, extending in the second direction. The locking member 42 is slidably disposed between the two limiting portions 13. Thus, the two limiting portions 13 can guide and limit the movement of the locking member 42. Specifically, when the transmission member 41 moves in the first direction, the limiting of the two limiting portions 13 restricts the sliding of the locking member 42 in the second direction. (Refer to...) Figure 5 and Figure 6 This can be understood as the locking member 42 sliding left and right when the transmission member 41 moves back and forth, that is, the locking member 42 moves closer to or away from the transmission member 41.

[0055] Reference Figure 17 The transmission member 41 has a first guide slope 412 on the side opposite to the second elastic member 43. As a result, when the external pin 61 is inserted, it will abut against the first guide slope 412. The inclined arrangement of the first guide slope 412 allows the external pin 61 to be inserted better and pushes the transmission member 41 to move in the direction of the second elastic member 43.

[0056] Reference Figure 11 and Figure 12The locking member 42 is provided with a first latching member 422, and the floating member 2 is provided with a second latching member 21. When the floating member 2 is in the retracted state, the first latching member 422 and the second latching member 21 latch together. Thus, the floating member 2 and the locking member 42 lock the floating member 2 within the housing 1 through this latching engagement. In some examples, the first latching member 422 can be a slot, and the second latching member 21 can be a block. In other examples, the first latching member 422 can be a block, and the second latching member 21 can be a slot.

[0057] Reference Figure 18 In some embodiments, the locking member 42 has a insertion groove 423, one side of which is a protective part 424, and the insertion groove 423 is located between the protective part 424 and the sliding groove 421; see reference Figure 8 and Figure 9 In the stored state, and in the insertion direction of the external pin 61, the protective part 424 at least partially covers the socket 22; in the use state, and in the insertion direction of the external pin 61, the socket 22 communicates with the insertion slot 423. Specifically, the insertion slot 423 is used for the insertion of the external pin 61. In the stored state, the protective part 424 at least partially covers the socket 22, which can be understood as the channel for the insertion of the pin 61 being blocked by the protective part 424. Thus, in the stored state, electric shock or external debris entering the housing 1 can be avoided, ensuring safety. In the use state, the socket 22 communicates with the insertion slot 423, allowing the external pin 61 to be inserted.

[0058] Reference Figure 7 and Figure 18 In some embodiments, the protective part 424 is provided with a second guide slope in the direction facing the insertion slot 423. Specifically, in the retracted state, the protective part 424 at least partially covers the insertion hole 22, and the second guide slope allows the external pin 61 to abut against the second guide slope when inserted. During the insertion of the pin 61, the external pin 61 also pushes the locking member 42, pushing the locking member 42 away from the transmission member 41, so that the locking member 42 can be more easily exposed in the insertion slot 423.

[0059] In some embodiments, the socket 22 includes a first socket 221 and a second socket 222; in the retracted state, and in the insertion direction of the external pin 61, the side of the transmission member 41 facing away from the second elastic member 43 partially covers the first socket 221, and the protective part 424 at least partially covers the second socket 222. Thus, the socket of this application can be used to insert a two-prong plug 6.

[0060] Reference Figure 16 and Figure 18In some embodiments, the locking member 42 further includes a support portion 425; in the use state, the support portion 425 abuts against the side of the floating member 2 facing the interior of the housing 1. Thus, in the use state, the locking member 42 moves away from the transmission member 41, and the support portion 425 can abut against the side of the floating member 2 facing the interior of the housing 1, preventing the floating member 2 from retracting into the housing 1.

[0061] Reference Figure 7 In some embodiments, the socket is provided with two locking members 42, which are arranged in a mirror-symmetrical manner. Specifically, the two locking members 42 are partially stacked together, and the sliding post 411 passes through both sliding grooves 421 simultaneously. When the transmission member 41 moves back and forth in the first direction, it can drive the two locking members 42 to form an unfolding and closing motion.

[0062] Reference Figure 3 In some embodiments, the socket 22 includes a first socket 221, a second socket 222, and a third socket 223. In the retracted state, and in the insertion direction of the external pin 61, the transmission member 41 partially obstructs the first socket 221, one locking member 42 at least partially obstructs the second socket 222, and another locking member 42 at least partially obstructs the third socket 223. Thus, the socket is a three-hole socket, capable of accepting a three-prong plug 6. The first socket 221 can be connected to the neutral wire, the second socket 222 can be connected to the live wire, and the third socket 223 can be connected to the ground wire.

[0063] In summary, the socket in this application, through the locking assembly 4, allows the floating member 2 to be housed inside the housing 1, meaning the floating member 2 is in a retracted state. This makes the socket thinner and lighter, saving space and making it easier to carry. When in use, the user simply inserts the pin 61, and the floating member 2 automatically releases its retracted state and protrudes from the housing 1. The socket's thickness increases accordingly to allow the external pin 61 to be fully inserted, while preventing the pin 61 from being exposed and causing safety hazards. Furthermore, the locking assembly 4 locks the floating member 2 in the use state, preventing it from retracting back into the housing 1 during use. This ensures the floating member 2 is stable and reliable during use, preventing loosening and improving the user experience while reducing potential safety risks.
