[0002] An adapter is an interface converter. It can be an independent hardware interface device that allows a hardware or electronic interface to be connected to other hardware or electronic interfaces, or it can be an information interface used in conjunction with other hardware. A power adapter is a relatively common type of adapter.
[0003] For an adapter with movable pins, especially a power adapter, the pins need to be manually operated by the user to make the pins in a retracted state or in an extended state for insertion into a socket.

[0070] This application discloses a pin self-locking component and an adapter, which include some or all of the technical features of the following embodiments; that is, the pin self-locking component and the adapter include some or all of the following structures. In one embodiment of this application, a pin self-locking component includes a pin, a pushing member, and a self-locking member that cooperates with the pushing member; the pushing member moves relative to the self-locking member along a moving direction, so that the pin has a retracted state parallel to the moving direction and an extended state perpendicular to the moving direction; in the extended state, the self-locking member abuts against the pushing member to lock the position of the pin. The above-mentioned pin self-locking component, through the cooperation of the pushing member, the self-locking member and the pin, forms a self-locking mechanism between the self-locking member and the pushing member when the pin is in the extended state to lock the pin, ensuring that the pin will not tip over during the process of inserting the pin into the socket. Therefore, the pin can be easily inserted into the target socket accurately without shrinking, which is convenient for users. The following combines Figures 1 to 23 , and details of the adapter will be described in detail.
[0071] In one of the embodiments, an adapter 900 is as Figure 1 and Figure 2 shown, which includes a housing assembly 200 and a pin self-locking component 500; the pin self-locking component 500 includes a pin 400, a pushing member 150, and a self-locking member 370; wherein, the self-locking member 370 cooperates with the pushing member 150, that is, the shape of the self-locking member 370 cooperates with the shape of the pushing member 150 to abut against each other at a certain position to lock the position of the pin 400.
[0072] Combined with Figure 3 and Figure 4, the pusher 150 moves relative to the self-locking member 370 along the moving direction 101, so that the pin 400 has a storage state parallel to the moving direction 101 as Figure 1 and Figure 2 shown, and can also be compared with Figure 5 and Figure 6 ; as an example, in the storage state, as Figure 2 shown, the self-locking member 370 is separated from the pusher 150 and also from the pin 400.
[0073] Moreover, the pusher 150 moves relative to the self-locking member 370 along the moving direction 101, and also makes the pin 400 have an unfolded state perpendicular to the moving direction 101 as Figure 15 and Figure 16 shown; in the unfolded state, the self-locking member 370 abuts against the pusher 150 to lock the position of the pin 400.
[0074] In one embodiment, as Figure 3 and Figure 4 shown, the pin self-locking assembly 500 further includes an elastic member 360 elastically abutting against the self-locking member 370; combined with Figure 7 , Figure 13 and Figure 16 , the self-locking member 370 is used to compress the elastic member 360 to elastically retreat when the pin 400 is adjusted from the storage state to the unfolded state, and abut against the pusher 150 to a predetermined position, and then elastically reset to lock the position of the pin 400; the self-locking member 370 is also used to elastically retreat to unlock the position of the pin 400 when the pin 400 is adjusted from the unfolded state to the storage state, and then elastically reset and separated from the pusher 150.
[0075] In one embodiment, as Figure 19 and Figure 20 shown, the pusher 150 is provided with an abutting surface, and the self-locking member 370 is provided with a protrusion 372 and a hook portion 378. In the unfolded state, the protrusion 372 abuts against the abutting surface of the pusher 150, and the hook portion 378 is clamped with the pin 400. As an example, combined with Figure 4 , Figure 7 and Figure 21, a first inclined surface 151, a first side surface 153, and a second inclined surface 152 are sequentially connected to the pusher 150; the self-locking member 370 is provided with a protrusion 372 and a hook portion 378, and a third inclined surface 373, a second side surface 375, and a fourth inclined surface 374 are sequentially connected to the protrusion 372; in a state where the pin 400 is adjusted from a received state to an unfolded state, a state where the second inclined surface 152 abuts against the third inclined surface 373, a state where the first side surface 153 abuts against the second side surface 375, and a state where the first inclined surface 151 abuts against the fourth inclined surface 374 are sequentially formed, and the hook portion 378 catches the pin 400 to lock the position of the pin 400; or, in a state where the pin 400 is adjusted from an unfolded state to a received state, the state where the first inclined surface 151 abuts against the fourth inclined surface 374, the state where the first side surface 153 abuts against the second side surface 375, and the state where the second inclined surface 152 abuts against the third inclined surface 373 are sequentially eliminated; and in a state where the state where the first inclined surface 151 abuts against the fourth inclined surface 374 is eliminated, the hook portion 378 releases the pin 400.
[0076] As Figure 1 and Figure 2 shown, the pin self-locking assembly 500 further includes a transmission assembly 100. As Figure 17 and Figure 18 shown, the transmission assembly 100 includes a sliding cover 110, a sliding plate 120, a rack plate 130, and a slideway frame 140; the pusher 150 is disposed under the sliding cover 110 or the sliding plate 120; in combination with Figure 21 , the sliding plate 120 is disposed under the sliding cover 110 and is slidably disposed in the slideway frame 140; the rack plate 130 is disposed under the sliding cover 110 or the sliding plate 120 and has a rack 131, and the rack 131 is in meshing engagement with the gear set 380. For an embodiment having a housing assembly 200, as an example, the slideway frame 140 is used to be disposed on the housing assembly 200, and the sliding plate 120 is slidably disposed in the slideway frame 140 to cooperate with the sliding cover 110 to close or open the accommodation cavity 240 of the housing assembly 200.
[0077] For the convenience of applying force, in one embodiment, as Figure 14 and Figure 15As shown, the transmission assembly 100 is provided with a force-receiving position 160 on the sliding cover 110. The force-receiving position 160 can be used as a finger placement position or a placement position for other parts to apply force. The force-receiving position 160 is used to better apply force to the transmission assembly through fingers, palms or other parts during use, so that the sliding cover 110 and the sliding plate 120 slide on the slideway frame 140, that is, to receive an external force to make the sliding cover 110 and the sliding plate 120 slide on the slideway frame 140. Exemplarily, in one embodiment, the force-receiving position 160 is a convex strip, a groove or a combination of concave and convex structures. In one embodiment, as Figure 18 and Figure 21 shown, the edge of the sliding plate 120 is provided with a bending portion 121. Combining Figure 12 , the slideway frame 140 is provided with a slideway 141 corresponding to the bending portion 121, and the bending portion 121 is slidably arranged in the slideway 141. In this embodiment, as Figure 10 and Figure 12 shown, bending portions 121 are respectively provided on both sides of the sliding plate 120, and each bending portion 121 is slidably arranged in a corresponding slideway 141.
[0078] In one embodiment, combining Figure 3 and Figure 4 , the pin self-locking assembly 500 further includes a gear group assembly 300. The gear group assembly 300 is provided with a gear group 380, the elastic member 360 and the self-locking member 370; the elastic member 360 and the self-locking member 370 are arranged adjacent to the gear group 380; the gear group 380 is used to connect the pin 400 to drive the pin 400 to rotate in a rotating state; the pushing member 150 moves relative to the self-locking member 370 along the moving direction 101, drives the gear group 380 to rotate through the transmission assembly 100, so as to drive the pin 400 to rotate to form the storage state or the deployment state. Exemplarily, the elastic member 360 is elastically abutted against the self-locking member 370. The self-locking member 370 is used to elastically retreat and abut against the pushing member 150 to a predetermined position in the state where the pin 400 is adjusted from the storage state to the deployment state, and then elastically reset to lock the position of the pin 400; the self-locking member 370 is further used to elastically retreat to unlock the position of the pin 400 in the state where the pin 400 is adjusted from the deployment state to the storage state, and then elastically reset and separated from the pushing member 150.
[0079] As an example, the pusher 150 is movably arranged to keep the gear set 380 of the gear set assembly 300 in a rotating state, and the pusher 150 approaches or moves away from the gear set 380 along the moving direction 101; the gear set 380 is used to connect the pin 400 to drive the pin 400 to rotate in the rotating state, so that the pin 400 has a receiving state parallel to the moving direction 101, and also makes the pin 400 have a deployed state perpendicular to the moving direction 101. As an example, when the gear set 380 is in one of the clockwise rotation and counterclockwise rotation states, the pusher 150 approaches the gear set 380 along the moving direction 101, and when the gear set 380 is in the other of the clockwise rotation and counterclockwise rotation states, the pusher 150 moves away from the gear set 380 along the moving direction 101.
[0080] Combined with Figure 3 , the housing assembly 200 is provided with a receiving cavity 240, and the gear set assembly 300 of the pin self-locking assembly 500 is located in the receiving cavity 240. Combined with Figure 4 , the gear set 380 of the gear set assembly 300 is rotatably arranged in the housing assembly 200, and the pin 400 is arranged on the gear set assembly 300; the pusher 150 of the pin self-locking assembly 500 is used to rotate the gear set assembly 300 to drive the pin 400 to rotate in the moving state, so that the pin 400 is in a receiving state parallel to the moving direction 101 and is completely located in the receiving cavity 240, or the pin 400 is in a deployed state perpendicular to the moving direction 101 and has a part located outside the receiving cavity 240.
[0081] As Figure 1 and Figure 2 shown in the embodiments, the pin self-locking assembly 500 further includes a transmission assembly 100. Combined with Figure 3 , the housing assembly 200 is provided with a receiving cavity 240, and the transmission assembly 100 is slidably arranged on the housing assembly 200, so that when the pin 400 is in the receiving state, the receiving cavity 240 is in a closed state as Figure 1 and Figure 3 shown, or when the pin 400 is in the adjustment state, the receiving cavity 240 is in a partially open state as Figure 5 and Figure 6 shown, or as Figure 8 and Figure 9 shown, or when the pin 400 is in the deployed state, the receiving cavity 240 is in an open state as Figure 14 and Figure 15As shown. Exemplarily, the transmission assembly 100 is respectively connected to the pushing member 150 and the pin 400, and is configured to drive the pushing member 150 to move relative to the self-locking member 370 along the moving direction 101 and drive the pin 400 to rotate in a sliding state, so that the pin 400 is in a retracted state or an extended state. When the pin 400 is in the retracted state, the transmission assembly 100 and the receiving cavity 240 together form a closed space, and the pin 400 is received in the closed space. Wherein, when the receiving cavity 240 is in a closed state, the pin 400 is in a retracted state parallel to the moving direction 101 and is completely located in the receiving cavity 240; and when the receiving cavity 240 is in an open state, the pin 400 is in an extended state perpendicular to the moving direction 101 and has a part located outside the receiving cavity 240. It should be noted that the pin self-locking assembly 500 can be the pin self-locking assembly 500 described in any embodiment.
[0082] In each embodiment, the gear set assembly 300 is located in the receiving cavity 240 and is disposed in the housing assembly 200. For the embodiment having the transmission assembly 100, the gear set assembly 300 is in meshing engagement with the transmission assembly 100; the pin 400 is disposed on the gear set assembly 300; the transmission assembly 100 is configured to rotate the gear set assembly 300 in a sliding state, that is, when the transmission assembly 100 is in a state of sliding relative to the housing assembly 200, so as to drive the pin 400 to rotate through the gear set assembly 300, so that the receiving cavity 240 is in the Figure 1 and Figure 3 shown closed state, the pin 400 is completely located in the receiving cavity 240, or the receiving cavity 240 is in the Figure 14 and Figure 15 shown open state, the pin 400 has a part located outside the receiving cavity 240 for insertion into a target socket.
[0083] In one embodiment, as Figure 10 and Figure 17As shown, the housing assembly 200 includes a front cover 210, a middle frame 220, and a bottom cover 230; the front cover 210, the middle frame 220, and the bottom cover 230 jointly enclose to form the accommodation cavity 240; the front cover 210 is disposed on the middle frame 220 by screwing or clamping, or integrally formed with the middle frame 220; the transmission assembly 100 is disposed on the middle frame 220 through a first connecting member 510; the gear set assembly 300, or its fixed bracket 340 and gear set 380, is disposed on the middle frame 220 through a second connecting member 520; the bottom cover 230 is disposed on the middle frame 220 through a third connecting member 530, or integrally formed with the middle frame 220; and, only one of the two cases exists where the front cover 210 is integrally formed with the middle frame 220 and the bottom cover 230 is integrally formed with the middle frame 220, that is, if the front cover 210 is integrally formed with the middle frame 220, the bottom cover 230 cannot be integrally formed with the middle frame 220; or if the bottom cover 230 is integrally formed with the middle frame 220, the front cover 210 cannot be integrally formed with the middle frame 220. Such a structural design is beneficial to the assembly of the transmission assembly 100, the housing assembly 200, and the gear set assembly 300.
[0084] In this embodiment, the first connecting member 510, the second connecting member 520, and the third connecting member 530 are all screws. In other embodiments, the first connecting member 510, the second connecting member 520, and the third connecting member 530 can also adopt snap connectors, etc.
[0085] In one of the embodiments, as Figure 17 and Figure 18 shown, the number of the slide racks 140 is a pair. Combining Figure 9 and Figure 10 , the slide racks 140 are disposed on the housing assembly 200 or its middle frame 220; the sliding plate 120 is disposed under the sliding cover 110 and is slidably disposed in the slide racks 140 to cooperate with the sliding cover 110 to make the accommodation cavity 240 in a closed state, a partially opened state, or an opened state. That is, in the transmission assembly 100, the slide racks 140 are fixed relative to the housing assembly 200. Therefore, in other embodiments, the slide racks 140 can also be used as a part of the housing assembly 200 and do not belong to the transmission assembly 100. In this embodiment, the sliding cover 110, the sliding plate 120, and the rack plate 130 are slidable relative to the housing assembly 200. Through the relative sliding of the sliding cover 110 and the housing assembly 200, the sliding cover 110 cooperates with the housing assembly 200 or its front cover 210 and middle frame 220 to jointly close the accommodation cavity 240 so that the pins 400 are enclosed and stored in the accommodation cavity 240, thereby realizing the protection of the pins 400 when the pins 400 are not in use.
[0086] In this embodiment, as Figure 18 and Figure 21 shown, the rack plate 130 is disposed under the sliding cover 110 or the sliding plate 120, and the rack plate 130 has a rack 131, and the rack 131 is in meshing engagement with the gear set 380 of the gear set assembly 300. As an example, the rack plate 130 is integrally formed with the sliding cover 110 or is disposed under the sliding cover 110 by screwing, bonding or welding. As an example, the sliding plate 120 is integrally formed with the sliding cover 110 or is disposed under the sliding cover 110 by screwing, bonding or welding.
[0087] After the pins of a traditional adapter are opened, there is no self-locking mechanism provided, and the pins may be reset to the folded state under force. For example, during the process of inserting the pins into a socket strip or a socket, the pins are prone to tipping. In one embodiment, as Figure 19 and Figure 20 shown, the transmission assembly 100 is provided with a pushing member 150, and the gear set assembly 300 is provided with an elastic member 360, a gear set 380 and a self-locking member 370 that cooperates with the pushing member 150; in combination with Figure 7 and Figure 11 , the pin 400 is disposed on the gear set 380, the gear set 380 is rotatably disposed in the housing assembly 200, and is in meshing engagement with the transmission assembly 100, so that when the transmission assembly 100 is in a sliding state, the gear set 380 rotates; in this embodiment, the gear set 380 is in meshing engagement with the rack 131 of the rack plate 130 of the transmission assembly 100. When the rack plate 130 is in a sliding state, the gear set 380 is driven to rotate by the rack 131, thereby driving the pin 400 to rotate.
[0088] In this embodiment, the elastic member 360 is elastically abutted against the self-locking member 370. As Figure 13 and Figure 16 shown, the self-locking member 370 is configured to elastically retreat and abut against the pushing member 150 to a predetermined position when the receiving cavity 240 changes from a partially opened state to a fully opened state, and then elastically reset to lock the position of the pin 400; as an example, the transmission assembly 100 slides on the housing assembly 200 to change the receiving cavity 240 from a partially opened state to a fully opened state. The self-locking member 370 first elastically retreats, and then when the receiving cavity 240 is in an opened state, the self-locking member 370 elastically resets and abuts against the pin 400 to lock the position of the pin 400. With such a structural design, when the receiving cavity 240 is in a fully opened state, the pin 400 is partially exposed outside the housing assembly 200 and is locked in position by the self-locking member 370, and can be inserted into a target socket, and during the insertion process, the pin 400 is not prone to tipping.
[0089] Moreover, the self-locking member 370 is further configured to elastically retreat to release the locking of the pin 400 when the receiving cavity 240 changes from the fully open state to the partially open state, and then elastically reset and be separated from the pushing member 150. Similarly, as an example, the transmission assembly 100 slides on the housing assembly 200 to change the receiving cavity 240 from the fully open state to the partially open state. The self-locking member 370 first elastically retreats, and then when the receiving cavity 240 is in the partially open state, the self-locking member 370 elastically resets, is separated from the pushing member 150, and is separated from the pin 400. Such a structural design realizes the unlocking of the pin 400 after being locked, making the adapter 900 easy to use.
[0090] In one embodiment, as Figure 4 and Figure 22 shown, the gear set assembly 300 is further provided with a fixing bracket 340. As an example, the fixing bracket 340 is fixed within the housing assembly 200; the fixing bracket 340 is provided with a gear receiving cavity 349, an elastic member receiving cavity 347, and a self-locking member receiving cavity 348; the elastic member 360 is disposed in the elastic member receiving cavity 347; the self-locking member 370 is disposed in the self-locking member receiving cavity 348; the gear set 380 is disposed in the gear receiving cavity 349; in this embodiment, the gear set assembly 300 is further provided with a spring shaft 361 and a fourth shaft 371, and the spring shaft 361 and the fourth shaft 371 respectively pass through the self-locking member 370; the elastic member 360 is a spring, and the spring is sleeved on the spring shaft 361 and elastically abuts against the self-locking member 370.
[0091] In this embodiment, the pushing member 150 is provided with a first inclined surface 151, a first side surface 153, and a second inclined surface 152 connected in sequence; the self-locking member 370 is provided with a protrusion 372 and a hook portion 378, and the protrusion 372 is provided with a third inclined surface 373, a second side surface 375, and a fourth inclined surface 374 connected in sequence; in combination with Figure 4 and Figure 7 , when the pushing member 150 approaches the gear set assembly 300 along the moving direction 101, or when the transmission assembly 100 is in a sliding state and the receiving cavity 240 changes from the partially open state to the open state, the second inclined surface 152 and the third inclined surface 373 first come into abutment, and then the pushing member 150 and the self-locking member 370 move relative to each other until the first side surface 153 and the second side surface 375 come into abutment. The pushing member 150 applies a pushing force to the self-locking member 370 to cause the self-locking member 370 to elastically retreat, and the hook portion 378 is displaced relative to the pin 400. In combination withFigure 13 and Figure 16 , then the pusher 150 and the self-locking member 370 move relative to each other until the first inclined surface 151 abuts against the fourth inclined surface 374, so that the self-locking member 370 is elastically reset, and the hook portion 378 catches the pin 400 to lock the position of the pin 400. With such a design, the locking of the pin 400 after it moves into place is achieved.
[0092] Vice versa, when the pusher 150 moves away from the gear set assembly 300 along the moving direction 101, or when the transmission assembly 100 is in a sliding state and the receiving cavity 240 changes from an open state to a partially open state, the pusher 150 and the self-locking member 370 move relative to each other until the first side surface 153 abuts against the second side surface 375, so that the self-locking member 370 elastically retreats, and the hook portion 378 avoids the pin 400 to release the locking of the position of the pin 400; the pusher 150 and the self-locking member 370 move relative to each other until the second inclined surface 152 abuts against the third inclined surface 373, and then they can continue to move so that the pusher 150 is separated from the self-locking member 370, which is similar to that described above and will not be elaborated here.

As an example, one of the gears is indirectly connected to the pusher 150 through the rack 131, and the other gear is used to connect the pin 400.

[0096] Among them, the transmission assembly 100 includes a sliding cover 110, a sliding plate 120, a rack plate 130, and a slideway frame 140. In this embodiment, a rack 131 is provided on the rack plate 130, and the rack plate 130 and the sliding cover 110 are integrally injection-molded. In other embodiments, the rack plate 130 can be fixed to the sliding cover 110 by means of screws, bonding, welding, etc.; in this embodiment, the sliding plate 120 is fixed to the sliding cover 110 by means of welding. In other embodiments, the sliding plate 120 can be fixed to the sliding cover 110 by a connecting member.

[0098] As an example, as Figure 2 and Figure 3 shown, the gear set assembly 300 includes a fixing bracket 340, a gear set 380, a bushing 350, etc., combined with Figure 22 and Figure 23, the gear set 380 includes a first gear 310, a second gear 320, a third gear 330, a first shaft 311, a second shaft 321, and a third shaft 331; the fixed bracket 340 is provided with a first hole 341, a second hole 342, a third hole 343, a fourth hole 344, a fifth hole 345, and a gear receiving cavity 349; during assembly, first place the first gear 310 into the gear receiving cavity 349, and the first shaft 311 sequentially passes through the two second holes 342 on the left side, the first gear 310, and the two second holes 342 on the right side, and the second gear 320 is fixed to the fixed bracket 340 through the interference fit between the first shaft 311 and the second hole 342; then place the second gear 320 into the gear receiving cavity 349, and the second shaft 321 sequentially passes through the fourth hole 344 on the left side, the second gear 320, and the fourth hole 344 on the right side, and the second gear 320 is fixed to the fixed bracket 340 through the interference fit between the second shaft 321 and the fourth hole 344; finally, install the third shaft 331 on the third gear 330, insert pins 400 are sleeved on both the left and right sides of the third gear 330, then place the third gear 330 into the gear receiving cavity 349, and finally pass a bushing 350 through the fifth hole 345 on the left side and sleeve it on the left end of the third shaft 331, and pass another bushing 350 through the fifth hole 345 on the right side and sleeve it on the right end of the third shaft 331, so that the third gear 330 and the insert pins 400 are fixed to the fixed bracket 340 through the interference fit between the bushing 350 and the fifth hole 345; the gear set assembly 300 further includes an elastic member 360, a self-locking member 370, a spring shaft 361, and a fourth shaft 371; during assembly, the fixed bracket 340 is provided with a first hole 341 and a third hole 343. First, place the elastic member 360 and the self-locking member 370 into the left spring receiving cavity 362 and the self-locking member receiving cavity 348 respectively, then the spring shaft 361 sequentially passes through the first hole 341 on the left side, the elastic member 360, the sixth hole 376 on the self-locking member 370, and another first hole 341, and then the fourth shaft 371 sequentially passes through the third hole 343 on the left side, the seventh hole 377 on the self-locking member 370, and then passes through another third hole 343 on the left side, so that the elastic member 360 and the self-locking member 370 are fixed to the left side of the fixed bracket 340 through the interference fit between the spring shaft 361 and the first hole 341, and the interference fit between the fourth shaft 371 and the third hole 343. The assembly of the elastic member 360 and the self-locking member 370 on the right side is the same as above and will not be elaborated.
[0099] As an example, such as Figure 10 and Figure 12As shown, a bending portion 121 is provided on the sliding plate 120 of the transmission assembly 100, and a slideway 141 is provided on the slideway frame 140; during assembly, the bending portion 121 is arranged in the slideway 141, and the bending portion 121 can slide in the slideway 141, so that the sliding plate 120 can slide in the slideway 141 of the sliding frame 140, and further the sliding cover 110 can slide left and right in the illustrated direction relative to the housing assembly 200 of the adapter 900.
[0100] As an example, when the transmission assembly 100 is in its original state, i.e., the initial state, the rack 131 engages with the first gear 310 on the gear set 380 or does not contact the first gear 310. At this time, the accommodation cavity 240 is in a closed state, and the sliding cover 110 covers the pins 400, playing a role in protecting the pins 400; combined Figure 3 、 Figure 6 、 Figure 9 and Figure 15 , when the sliding cover 110 of the transmission assembly 100 starts to slide left in the illustrated direction, after sliding a certain distance, when the rack 131 starts to engage with the first gear 310, the rack 131 drives the first gear 310 to rotate, the first gear 310 drives the second gear 320 to rotate, and the second gear 320 drives the third gear 330 to rotate, thereby driving the pins 400 on the shaft of the third gear 330 to rotate counterclockwise, thus starting to open the pins 400, that is, adjusting the pins 400 from the storage state to the unfolded state; after the sliding cover 110 continues to slide a certain distance, when the rack 131 disengages from the first gear 310, at this time the pins 400 have been fully opened, that is, the included angle with the adapter housing is 90 degrees, and at this time the pins 400 can be inserted into an appropriate socket; combined with Figure 1 、 Figure 5 、 Figure 8 and Figure 14 , when the pins 400 are to be stored, the sliding cover 110 slides right in the illustrated direction. When the rack 131 starts to engage with the first gear 310, the rack 131 drives the first gear 310 to rotate, the first gear 310 drives the second gear 320 to rotate, and the second gear 320 drives the third gear 330 to rotate, thereby driving the pins 400 on the shaft of the third gear 330 to start rotating clockwise, thus starting to store the pins 400, and at this time the sliding cover 110 completely covers the pins 400.
[0101] As an example, a pusher 150 is provided on the sliding cover 110 of the transmission assembly 100. A first inclined surface 151, a second inclined surface 152 and a first side surface 153 are provided on the pusher 150. A self-locking member 370 is provided on the gear set assembly 300. A protrusion 372 and a hook portion 378 are provided on the self-locking member 370. A third inclined surface 373, a fourth inclined surface 374 and a second side surface 375 are provided on the protrusion 372. When the transmission assembly 100 is in its original state, i.e., the initial state, the sliding cover 110 is disposed on the housing assembly 200 and the accommodating cavity 240 is in a closed state. There is a certain distance between the pusher 150 and the self-locking member 370. At this time, the sliding cover 110 covers the pin 400, playing a role in protecting the pin 400. When the sliding cover 110 of the transmission assembly 100 starts to slide, shown as sliding to the left in the figure, after the sliding cover 110 slides a certain distance, the second inclined surface 152 on the pusher 150 starts to abut against the third inclined surface 373 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110, the pusher 150 applies a certain force to the self-locking member 370, causing the pusher 150 to move away from the gear set 380 and the self-locking member 370 to compress the elastic member 360. Thus, the first side surface 153 on the pusher 150 cooperates with the second side surface 375 on the protrusion 372 of the self-locking member 370. After sliding a certain distance, the first side surface 153 on the pusher 150 separates from the second side surface 375 on the protrusion 372 of the self-locking member 370. At this time, the elastic member 360 resumes its original state, and the first inclined surface 151 on the pusher 150 abuts against the fourth inclined surface 374 on the protrusion 372 of the self-locking member 370. At this time, the hook portion 378 on the self-locking member 370 hooks the pin 400, completing the self-locking of the pin 400. When unlocking is required, when the sliding cover 110 starts to slide to the right, the first inclined surface 151 on the pusher 150 starts to abut against the fourth inclined surface 374 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110 of the transmission assembly 100, the pusher 150 applies a certain force to the self-locking member 370, causing the pusher 150 to move away from the gear set 380 and the self-locking member 370 to compress the elastic member 360. Thus, the unlocking of the pin 400 is completed. At this time, the first side surface 153 on the pusher 150 cooperates with the second side surface 375 on the protrusion 372 of the self-locking member 370. After sliding a certain distance, the first side surface 153 on the pusher 150 separates from the second side surface 375 on the protrusion 372 of the self-locking member 370. At this time, the elastic member 360 resumes its original state, and the second inclined surface on the pusher 150 abuts against the third inclined surface 373 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110 until the sliding cover 110 slides to the original state to cover the pin 400, as Figure 4 , Figure 7 , Figure 13 and Figure 5 shown.
[0102] With such a structural design, the user can open and fold the pin 400 with one hand, which is more convenient to use. The sliding cover can better protect the pin 400 and prevent foreign objects or dirt on the pin 400 from affecting its electrical performance. After the pin 400 is opened, it is self-locked through a self-locking mechanism to ensure that the pin 400 will not tip over during the process of inserting the pin 400 into a socket strip or a socket.
[0103] It should be noted that other embodiments of the present application further include a pin self-locking assembly and an adapter formed by the combination of the technical features in the above embodiments and capable of being implemented.
[0104] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0105] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
