It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This application provides a safety socket, a power bank, and an electrical device, which are characterized by higher water resistance and safety.

[0038] Figure 1 This is a schematic diagram of the structure of a safety socket provided in an embodiment of this application. Figure 2 This is a schematic diagram of a power bank module provided in an embodiment of this application.

[0039] like Figure 1 and Figure 2 As shown, this application embodiment first provides a safety socket 100, which can be applied to a power supply, which can be a power bank 1000, a mains power supply, or a power strip. The power bank 1000 includes the safety socket 100, a battery assembly 200, and a housing 300. The battery assembly 200 is disposed within the housing 300, and the safety socket 100 is embedded in the housing 300, and is electrically connected to the battery assembly 200.

[0040] The safety socket 100 can be used in cooperation with a plug having a plurality of prongs. An electrical device can be plugged into the safety socket 100 via the prongs of the plug to draw power from the battery assembly 200. In the example of the present application, the prongs are of a three-pronged plug, and the prongs include a ground prong, a neutral prong and a hot prong. For ease of understanding, the ground prong of the socket is defined as a first prong, and the neutral prong and the hot prong of the socket are both defined as second prongs.

[0041] Figure 3 An exploded view of the safety socket provided in the example of the present application.

[0042] Please refer to Figure 3 The safety socket 100 includes a housing 10, a first conductive clip 20 and a second conductive clip 30. The housing 10 has an accommodating cavity formed inside, and the housing 10 has at least two waterproof compartments 50.

[0043] The first conductive clip 20 and the second conductive clip 30 are arranged in different waterproof compartments 50, and the first conductive clip 20 and the second conductive clip 30 are respectively used for plugging different prongs of the plug. The first conductive clip 20 and the second conductive clip 30 are both electrically connected to the battery assembly 200. In the example of the present application, the first conductive clip 20 is used for plugging the first prong, and the second conductive clip 30 is used for plugging the second prong. The plugging direction of the prongs is parallel to the Z-axis direction in the drawing.

[0044] Each waterproof compartment 50 forms a space separated from each other inside the housing 10. By arranging the first conductive clip 20 and the second conductive clip 30 in different waterproof compartments 50, water outside the waterproof compartment 50 can be prevented from entering the inside of the waterproof compartment 50 to interfere with the first conductive clip 20 or the second conductive clip 30, thereby achieving a waterproof effect.

[0045] For ease of understanding, the waterproof compartment 50 provided with the first conductive clip 20 is defined as a first waterproof compartment 51, and the waterproof compartment 50 provided with the second conductive clip 30 is defined as a second waterproof compartment 52.

[0046] Figure 4 Structural diagrams of the pusher mechanism, the conductive switch, the first conductive clip, the second conductive clip and the elastic member provided in the example of the present application.

[0047] Please refer to Figure 4For example, the first conductive clamp 20 has a clamp body 21 arranged in the first waterproof compartment 51, and a certain distance is left between the clamp body 21 and the bottom wall of the shell 10. The clamp body 21 is provided with two oppositely arranged conductive clamp pieces, and a spacing space is left between the two conductive clamp pieces. When the plug is inserted into the safety socket 100, the first pin is inserted and arranged in the clamp body 21, and the two conductive clamp pieces of the clamp body 21 cooperate to clamp the first pin to establish an electrical connection.

[0048] For example, the second conductive clamp 30 has a clamp head 31 arranged in the second waterproof compartment 52. When the plug is inserted into the safety socket 100, the second pin is inserted into the clamp head 31, and the clamp head 31 clamps the second pin to establish an electrical connection.

[0049] In some embodiments, the safety socket 100 further comprises a cover plate 40. The cover plate 40 is arranged on the shell 10 and covers the cavity opening of the accommodating cavity to cover the waterproof compartment 50. The cover plate 40 is provided with a first insertion hole 41 and a second insertion hole 42, both of which penetrate through both sides of the cover plate 40. The first insertion hole 41 is used for the first conductive clamp 20 to pass through the corresponding pin, and the second insertion hole 42 is used for the second conductive clamp 30 to pass through the corresponding pin.

[0050] In some embodiments, the safety socket 100 further comprises a waterproof pad 43, wherein the waterproof pad 43 is arranged between the cover plate 40 and the waterproof compartment 50. For example, the waterproof pad 43 is arranged on the side of the waterproof compartment 50 away from the bottom wall of the shell 10. The edge profile of the waterproof pad 43 is matched with the edge profile of the surrounding plate, and the waterproof pad 43 is provided with a plurality of through holes corresponding to the insertion holes, which can be used for the pins to pass through.

[0051] It can be understood that the waterproof pad 43 plays a waterproof role between the cover plate 40 and the waterproof compartment 50, prevents water outside the cover plate 40 from entering the waterproof compartment 50 to interfere with the work of the electronic elements, and improves the safety.

[0052] Figure 5 The structural schematic diagram of the safety socket provided by the embodiment of the present application when the conductive switch is turned off. Figure 6 The structural schematic diagram of the safety socket provided by the embodiment of the present application when the conductive switch is turned on.

[0053] Please refer to Figure 5 and Figure 6In some embodiments, the safety socket 100 further comprises a conductive switch 60 and a pushing mechanism 70. The conductive switch 60 is located outside the waterproof compartment 50 and is electrically connected with the first conductive clamp 20 or the second conductive clamp 30. The conductive switch 60 has an off state and an on state. When the conductive switch 60 is in the off state, the first conductive clamp 20 and the second conductive clamp 30 are disconnected; when the conductive switch 60 is in the on state, the first conductive clamp 20 and the second conductive clamp 30 are connected in conduction.

[0054] The pushing mechanism 70 is arranged in the waterproof compartment 50 adjacent to the conductive switch 60. The pushing mechanism 70 has a push rod 71 which is in dynamic sealing cooperation with the wall of the waterproof compartment 50. The pushing mechanism 70 is configured to drive the push rod 71 to at least partially extend out of the waterproof compartment 50 along a first direction under the pressure of the corresponding pin, so as to trigger the conductive switch 60 to be in the on state. The first direction is parallel to the Y-axis direction in the figure.

[0055] When the plug is not inserted into the safety socket 100, the pin does not press the pushing mechanism 70, the conductive switch 60 is in the off state, and the first conductive clamp 20 and the second conductive clamp 30 are disconnected. At this time, the risk of electric leakage after the socket is flooded or damp can be reduced, and the safety can be improved.

[0056] When the plug is inserted into the safety socket 100, the pin presses the pushing mechanism 70, and the pushing mechanism 70 drives the push rod 71 to move to trigger the conductive switch 60 to be in the on state, and the first conductive clamp 20 and the second conductive clamp 30 are connected in conduction. At this time, the plug and the safety socket 100 can be normally connected.

[0057] In some embodiments, the conductive switch 60 comprises a first contact piece 61 and a second contact piece 62 which are connected with the first conductive clamp 20 and the second conductive clamp 30 respectively. The first contact piece 61 and the second contact piece 62 are spaced apart along the first direction, and the push rod 71 is located on the side of the second contact piece 62 away from the first contact piece 61. The second contact piece 62 is configured to move towards the first contact piece 61 under the pressure of the push rod 71 extending out of the waterproof compartment 50.

[0058] When the push rod 71 moves towards the second contact piece 62 along the first direction, the push rod 71 presses the second contact piece 62, so that the second contact piece 62 contacts the first contact piece 61. When the push rod 71 moves away from the second contact piece 62 along the first direction, the second contact piece 62 rebounds to be separated from the first contact piece 61. In this way, the conductive switch 60 can be switched between the off state and the on state.

[0059] Specifically, when the plug is not inserted into the safety socket 100, the push rod 71 does not press the second contact piece 62, and a space is maintained between the second contact piece 62 and the first contact piece 61, so that the second contact piece 62 is disconnected from the first contact piece 61, and at this time the conductive switch 60 is in the off state.

[0060] When the plug is inserted into the safety socket 100, the push rod 71 presses the second contact piece 62 away from the side of the first contact piece 61, the second contact piece 62 moves towards the first contact piece 61 and contacts the first contact piece 61, the second contact piece 62 is in conduction with the first contact piece 61, at this time, the conductive switch 60 is in the conduction state.

[0061] In the examples of the present application, the first contact piece 61 is electrically connected with the first conductive clamp 20, and the second contact piece 62 is electrically connected with the second conductive clamp 30. In other embodiments, the first contact piece 61 can be electrically connected with the second conductive clamp 30, and the second contact piece 62 can be electrically connected with the first conductive clamp 20, and the present application does not limit this.

[0062] The first contact piece 61 and the second contact piece 62 are arranged between the outer wall of the first waterproof compartment 51 and the inner wall of the shell 10, and the projections of the first contact piece 61, the second contact piece 62 and the push rod 71 on the inner wall of the shell 10 overlap in the first direction. The first contact piece 61 is fixed to the shell 10, and the first contact piece 61 is electrically connected with the first conductive clamp 20 through a lead wire.

[0063] Figure 7 The structure diagram of the first contact piece, the second contact piece, the second conductive clamp, the push rod and the pusher provided by the embodiments of the present application.

[0064] Please refer to Figure 7 The second contact piece 62 has a connecting portion 621 and a contact portion 622, and the connecting portion 621 and the contact portion 622 are arranged in a bending manner at the connection position and have elasticity. The connecting portion 621 is connected with the second conductive clamp 30, and the contact portion 622 is distributed in the first direction with the first contact piece 61.

[0065] For example, the second contact piece 62 is integrally formed, the connecting portion 621 and the contact portion 622 are processed by a bending process, the contact portion 622 is parallel to the first contact piece 61, and the connecting portion 621 is perpendicular to the contact portion 622. One end of the connecting portion 621 is connected with the contact portion 622, and the other end of the connecting portion 621 is connected with the second conductive clamp 30.

[0066] When the plug is not inserted into the safety socket 100, a spacing is maintained between the contact portion 622 and the first contact piece 61, at this time, the conductive switch 60 is in the open state.

[0067] When the plug is inserted into the safety socket 100, the push rod 71 presses the contact portion 622 away from the side of the first contact piece 61, the contact portion 622 is deformed and bent towards the first contact piece 61, the contact portion 622 moves towards the first contact piece 61 and contacts the first contact piece 61, at this time, the conductive switch 60 is in the conduction state.

[0068] When the plug is pulled out of the safety socket 100, the contact portion 622 loses the pressure touch of the push rod 71 and restores the deformation, so as to move the contact portion 622 away from the first contact piece 61.

[0069] In this way, by using the elasticity of the second contact piece 62, the conductive switch 60 can be automatically switched to the off state after the plug is pulled out of the safety socket 100.

[0070] On the other hand, the second contact piece 62 in the embodiment is arranged to move in a way of elastic deformation, so as to realize the contact and separation with the first contact piece 61. In this way, the entire second contact piece 62 does not need to be moved, the moving distance or the pushing force required for switching the on-off state is shortened, and the switching efficiency of the on-off state is improved.

[0071] In some embodiments, the pushing mechanism 70 includes a transmission member 72 and a pushing member 73, both of which are arranged in the first waterproof compartment 51.

[0072] The transmission member 72 is located on the side of the first conductive clamp 20 facing the bottom wall of the shell 10, i.e. between the clamp body 21 and the bottom wall of the shell 10. The transmission member 72 is in sliding fit with the shell 10 along a second direction. The first direction and the second direction have an included angle, and both the first direction and the second direction have an included angle with the plug-in direction of the pin, and the second direction is parallel to the X-axis direction in the figure.

[0073] The pushing member 73 is connected to the push rod 71, and the transmission member 72 is in transmission connection with the pushing member 73. The pushing member 73 is in sliding fit with the shell 10 along the first direction.

[0074] The transmission member 72 is configured to move along the second direction under the pressure touch of the corresponding pin, and drive the pushing member 73 to move along the first direction.

[0075] When the plug is inserted into the socket 100, the first pin can move through the first conductive clamp 20 towards the transmission member 72 and press the transmission member 72, so as to push the transmission member 72 to move along the second direction to approach the second contact piece 62, and the transmission member 72 drives the pushing member 73 to move along the first direction, and the pushing member 73 drives the push rod 72 to extend out of the first waterproof compartment 51 along the first direction and press the second contact piece 62, so that the first contact piece 61 contacts with the second contact piece 62. In this way, the linkage between the socket insertion action and the on-off switching of the conductive switch 60 is realized.

[0076] Figure 8 The explosion diagram of the pushing member mechanism, the conductive switch, the first conductive clamp, the second conductive clamp and the elastic member provided in the embodiments of the present application.

[0077] Please refer to Figure 8In some embodiments, the transmission member 72 is provided with a guide surface 721 on the side facing the first conductive clamp 20, which is used for the pin to press against and drive the transmission member 72 to move in the second direction. The first direction and the second direction are both at an angle with the extension direction of the guide surface 721.

[0078] In the process of the first pin being inserted through the first conductive clamp 20, the first pin presses against the guide surface 721, and under the action of the guide surface 721, the transmission member 72 can move in the second direction following the insertion of the first pin, so as to realize the transmission between the first pin and the transmission member 72.

[0079] In some embodiments, the transmission member 72 is provided with an arc-shaped groove on the side facing the clamp body 21, and the groove bottom of the arc-shaped groove forms the guide surface 721. In this way, the stress effect of the guide surface 721 can be improved, and at the same time, the first pin can be prevented from being stuck when pressing against the guide surface 721, and the transmission efficiency can be improved.

[0080] In some embodiments, the transmission member 72 is provided with a positioning sliding block 723 which moves synchronously with the transmission member 72. For example, the positioning sliding block 723 is protruded from the side of the transmission member 72 away from the clamp body 21. The bottom wall of the shell 10 is provided with a positioning sliding groove (not shown in the figure) which extends in the second direction. The positioning sliding block 723 is slidingly arranged in the positioning sliding groove. When the transmission member 72 moves in the second direction, the positioning sliding block 723 slides in the positioning sliding groove.

[0081] In this way, the positioning sliding groove plays a limiting and positioning role on the movement of the transmission member 72 through the positioning sliding block 723, which prevents the transmission member 72 from deviating from the second direction in the movement process, and at the same time, ensures that the position of the transmission member 72 can be aligned with the first conductive clamp 20.

[0082] In some embodiments, the transmission member 72 is provided with a first transmission surface 724 on the side facing the pushing member 73. The first transmission surface 724 is used to drive the pushing member 73 to move in the first direction when the transmission member 72 moves in the second direction. The first direction and the second direction are both at an angle with the extension direction of the first transmission surface 724.

[0083] When the transmission member 72 moves in the second direction, the transmission member 72 presses against the pushing member 73 through the first transmission surface 724, and under the action of the first transmission surface 724, the pushing member 73 moves in the first direction following the movement of the transmission member 72, so as to realize the transmission between the transmission member 72 and the pushing member 73.

[0084] In some embodiments, the pushing member 73 is provided with a second transmission surface 731 on one side of the transmission member 72. The second transmission surface 731 is used for being pressed by the transmission member 72 when the transmission member 72 moves in the second direction, and drives the pushing member 73 to move in the first direction. The first direction and the second direction are both at an angle with the extension direction of the second transmission surface 731. For example, the first transmission surface 724 and the second transmission surface 731 are parallel to each other.

[0085] When the transmission member 72 moves in the second direction, the transmission member 72 presses the second transmission surface 731 of the pushing member 73, and the pushing member 73 moves in the first direction following the movement of the transmission member 72 under the action of the second transmission surface 731, so as to realize the transmission between the transmission member 72 and the pushing member 73.

[0086] For example, the pushing member 73 has two pushing members 73 respectively on both sides of the transmission member 72 in the first direction, and the transmission member 72 is provided with the second transmission surface 731 on both sides in the first direction.

[0087] It is worth noting that in the example of the present application, the transmission member 72 is provided with the first transmission surface 724, and the pushing member 73 is provided with the second transmission surface 731. In this way, during the relative movement of the transmission member 72 and the pushing member 73, the first transmission surface 724 abuts against the second transmission surface 731, that is, the transmission is realized by the cooperation of the first transmission surface 724 of the transmission member 72 and the second transmission surface 731 of the pushing member 73, which can improve the transmission efficiency and smoothness between the pushing member 73 and the transmission member 72, and at the same time, the overall volume of the pushing member 73 and the transmission member 72 can be reduced, and the overall structure can be simplified.

[0088] In other embodiments, the transmission between the pushing member 73 and the transmission member 72 can also be realized by one of the first transmission surface 724 and the second transmission surface 731, which is not limited in the present application.

[0089] In some embodiments, the pushing member 73 is provided with a limiting sliding block 732, and the limiting sliding block 732 moves synchronously with the pushing member 73. For example, the limiting sliding block 732 is protruded from the side surface of the pushing member 73. The bulkhead of the first waterproof compartment 51 is provided with a limiting sliding groove (not shown in the figure), which extends in the first direction, and the limiting sliding block 732 is slidingly arranged in the limiting sliding groove.

[0090] When the pushing member 73 moves in the first direction, the limiting sliding block 732 slides in the limiting sliding groove. In this way, the limiting sliding groove limits the movement of the pushing member 73 through the limiting sliding block 732, preventing the pushing member 73 from deviating from the first direction during the movement.

[0091] In some embodiments, the pusher 73 is provided with a limiting slider 732 at each of the opposite ends in the second direction. Correspondingly, the first waterproof compartment 51 is provided with a corresponding limiting sliding groove at each of the opposite walls in the second direction, and the limiting slider 732 is slidingly arranged in the corresponding limiting sliding groove.

[0092] In this way, the waterproof compartment 50 can slide and limit the two ends of the pusher 73 through the two sets of limiting sliding grooves, thereby reducing the risk of tilting or jamming of the pusher 73 during sliding.

[0093] In some embodiments, the pusher 73 is suspended relative to the bottom wall of the shell 10, so that a space is left between the pusher 73 and the bottom wall of the shell 10. In this way, other structures can be arranged in the space between the pusher 73 and the bottom wall of the shell 10, thereby improving the space utilization of the first waterproof compartment 51.

[0094] It can be understood that the pusher 73 is in clamped connection with the waterproof compartment 50 through the limiting sliders 732 at the two ends, which can maintain a space between the pusher 73 and the bottom wall of the shell 10, and the pusher 73 can move relatively in the first direction within the shell 10. The limiting slider 732 simultaneously plays the roles of sliding limiting and supporting, and the structure design is more ingenious.

[0095] In some embodiments, the pusher 73 is provided with a plurality of limiting sliders 732 at the two ends, respectively, and the plurality of limiting sliders 732 are spaced apart along the depth direction of the shell 10. Correspondingly, the first waterproof compartment 51 is provided with a pair of limiting sliding grooves at each of the opposite walls in the second direction.

[0096] For example, the limiting sliders 732 and the limiting sliding grooves are arranged in pairs. In this way, the two ends of the pusher 73 can be connected to the first waterproof compartment 51 through the plurality of limiting sliders 732, respectively, thereby improving the installation stability and sliding limiting effect of the pusher 73.

[0097] In some embodiments, the push rod 71 is arranged to extend in the first direction. The push rod 71 is arranged to pass through the first waterproof compartment 51 and form a dynamic sealing cooperation with the first waterproof compartment 51. One end of the push rod 71 is located in the first waterproof compartment 51 and is fixedly connected with the pusher 73. The other end of the push rod 71 extends out of the first waterproof compartment 51 and is close to the side of the second contact piece 62 away from the first contact piece 61.

[0098] For example, the first waterproof compartment 51 is provided with a sealing hole, and the push rod 71 passes through the sealing hole and is in clearance cooperation with the sealing hole to achieve dynamic sealing cooperation. In this way, the push rod 71 can move relatively in the first direction with respect to the first waterproof compartment 51, and water outside the first waterproof compartment 51 cannot enter the inside of the first waterproof compartment 51 through the connection between the push rod 71 and the first waterproof compartment 51, thereby achieving a waterproof effect.

[0099] In some embodiments, the safety socket 100 further comprises a resilient member 90, which is arranged in the waterproof compartment 50 where the pushing mechanism 70 is located.

[0100] The resilient member 90 is configured to be compressed when the pushing mechanism 70 is pressed by the pins of the plug. The resilient member 90 is further configured to recover and drive the pushing mechanism 70 to reset when the pushing mechanism 70 is not pressed by the pins of the plug.

[0101] When the plug is inserted into the safety socket 100, the pushing mechanism 70 is moved under the pressing of the pins of the plug. The pushing mechanism 70 causes the resilient member 90 to be compressed. When the plug is pulled out of the safety socket 100, the resilient member 90 recovers and drives the pushing mechanism 70 to move in the opposite direction, so that the pushing mechanism 70 is reset to the state when the plug is not inserted into the safety socket 100, so that the pins can press the pushing mechanism 70 again after being inserted into the safety socket 100.

[0102] In this way, the resilient member 90 can assist the pushing mechanism 70 to reset after the plug is pulled out of the safety socket 100, which helps the conductive switch 60 to automatically switch to the power-off state.

[0103] For example, the resilient member 90 is a compression spring, which is arranged between the side of the pushing member 73 away from the transmission member 72 and the wall of the first waterproof compartment 51.

[0104] When the plug is inserted into the safety socket 100, the transmission member 72 advances under the pressing of the pins of the plug, and drives the pushing member 73 and the push rod 71 to move towards the second contact piece 62. At this time, the push rod 71 is pressed to deform the second contact piece 62, and the pushing member 73 compresses the resilient member 90 in cooperation with the first waterproof compartment 51.

[0105] When the plug is pulled out of the safety socket 100, the resilient member 90 recovers and drives the transmission member 72 to move away from the second contact piece 62. The pushing member 73 drives the push rod 71 to move away from the second contact piece 62. The pushing member 73 drives the transmission member 72 to retreat until the transmission member 72, the pushing member 73 and the push rod 71 are respectively moved to the positions when the plug is not inserted into the safety socket 100. The second contact piece 62 rebounds and separates from the first contact piece 61, so as to realize automatic reset.

[0106] In some embodiments, the resilient member 90 is wound around the end of the push rod 71 located in the first waterproof compartment 51. The push rod 71 can support and limit the resilient member 90, so as to prevent the resilient member 90 from being bent or excessively deformed and damaged, and improve the stability of the resilient member 90.

[0107] In the example of the present application, the plug is a three-pin plug, which has one first pin and two second pins. The first pin is a ground pin. The two second pins are respectively a zero pin and a fire pin. Figure 9The layout schematic diagram of the first conductive clamp and the second conductive clamp provided by the embodiment of the present application.

[0108] Please refer to Figure 9 The first conductive clamp 20 has one, and the first conductive clamp 20 is used for inserting the ground pin. The first conductive clamp 20 can be regarded as a ground conductive clamp.

[0109] The second conductive clamp 30 and the conductive switch 60 each have two, and the two conductive switches 60 are respectively connected to the two second conductive clamps 30. The two second conductive clamps 30 are respectively a zero line conductive clamp 30A and a fire line conductive clamp 30B. The zero line conductive clamp 30A is used for inserting the zero line pin, and the fire line conductive clamp 30B is used for inserting the fire line pin.

[0110] The two conductive switches 60 are respectively a zero line conductive switch 60A and a fire line conductive switch 60B. The zero line conductive switch 60A is connected to the zero line conductive clamp 30A, and the fire line conductive switch 60B is connected to the fire line conductive clamp 30B. For example, the zero line conductive clamp 30A and the fire line conductive clamp 30B are symmetrically distributed, and the symmetry line is parallel to the second direction and passes through the center point of the transmission member 72.

[0111] The first waterproof compartment 51 has one, and the first conductive clamp 20 is arranged in the first waterproof compartment 51. The second waterproof compartment 52 has two, which are respectively a zero line waterproof compartment 52A and a fire line waterproof compartment 52B. The zero line conductive clamp 30A is arranged in the zero line waterproof compartment 52A, and the fire line conductive clamp 30B is arranged in the fire line waterproof compartment 52B.

[0112] The pushing mechanism 70 is arranged in the first waterproof compartment 51, and the pushing mechanism 70 has two push rods 71. The two push rods 71 are respectively arranged corresponding to the two conductive switches 60. The two push rods 71 are respectively a zero line push rod 71A and a fire line push rod 71B. The zero line push rod 71A is arranged corresponding to the zero line conductive switch 60A, and the fire line push rod 71B is arranged corresponding to the fire line conductive switch 60B.

[0113] The pushing mechanism 70 is configured to drive the zero line push rod 71A and the fire line push rod 71B to respectively extend out of the two second waterproof compartments 52 under the pressure of the ground pin, so as to trigger the zero line conductive switch 60A and the fire line conductive switch 60B to conduct.

[0114] Specifically, the pushing mechanism 70 includes one pushing member 73 and two pushing members 73. The two pushing members 73 are respectively transmissionally connected to the two sides of the pushing member 73, and the two push rods 71 are respectively fixed to the two pushing members 73. The two pushing members 73 are respectively a zero line pushing member 73A and a fire line pushing member 73B. The zero line pushing member 73A is connected to the zero line push rod 71A, and the fire line pushing member 73B is connected to the fire line push rod 71B.

[0115] The elastic member 90 has two, namely a zero line elastic member 90A and a fire line elastic member 90B, the zero line elastic member 90A is arranged on the zero line push rod 71A and used to push the zero line push member 73A, and the fire line elastic member 90B is arranged on the fire line push rod 71B and used to push the fire line push member 73B.

[0116] When the ground pin is not inserted into the first conductive clamp 20, the zero line conductive switch 60A and the fire line conductive switch 60B are simultaneously disconnected.

[0117] When the ground pin is inserted into the first conductive clamp 20, the first pin pressure touch transmission member 72 moves, and the transmission member 72 drives the zero line push member 73A and the fire line push member 73B to move respectively. The zero line push member 73A drives the zero line push rod 71A to extend out of the corresponding second waterproof compartment 52 to trigger the zero line conductive switch 60A to conduct, and at the same time, the fire line push member 73B drives the fire line push rod 71B to extend out of the corresponding second waterproof compartment 52 to trigger the fire line conductive switch 60B to conduct.

[0118] When the ground pin is pulled out of the first conductive clamp 20, the zero line push member 73A and the fire line push member 73B are reset under the action of the corresponding elastic member 90 respectively, the zero line push member 73A and the fire line push member 73B jointly push the transmission member 72 to reset, and the zero line push member 73A and the fire line push member 73B drive the zero line push rod 71A and the fire line push rod 71B to reset respectively.

[0119] In this way, when the plug is not inserted into the safety socket 100, the zero line conductive clamp 30A and the fire line conductive clamp 30B are simultaneously disconnected with the first conductive clamp 20, further reducing the risk of electric shock accidents and improving safety.

[0120] In addition, during the process of inserting the plug into the safety socket 100, the transmission member 72 can drive the zero line push member 73A and the fire line push member 73B to move respectively, the transmission efficiency is higher, the structure is more exquisite, the production cost and the failure rate are reduced.

[0121] It is worth noting that the above description is intended to illustrate the cooperation between the plug and the safety socket 100, and is not limited to the specific structure of the safety socket 100. In actual application, the selection or position of the first conductive clamp 20 and the second conductive clamp 30 in the safety socket 100 and other related structures can be adaptively configured according to the plug, and the present application does not limit this.

The portable power bank 1000 includes a housing 300, a battery assembly 200, and a safety socket 100 in any of the foregoing embodiments. The battery assembly 200 is disposed within the housing 300, and the safety socket 100 is embedded in the housing 300 and electrically connected to the battery assembly 200.

Furthermore, the power device can also use the safety socket 100 of the power bank 100 to power other devices, thus meeting the power needs of those other devices.
